CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q (“Quarterly Report”) contains “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that involve substantial risk and uncertainties.
All statements, other than statements of historical fact, contained or incorporated by reference in this Quarterly Report, including statements regarding the strategy, future operations, future financial position, projected costs, prospects, plans and objectives of management, are forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on current expectations and beliefs of our management, as well as assumptions made by, and information currently available to, our management, and are subject to risks and uncertainties. There can be no assurance that future developments affecting us will be those that we have anticipated. Forward-looking statements include, but are not limited to, statements concerning the following:
We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have included important factors in this Quarterly Report under the heading “Risk Factors” in Part II, Item 1A. “Risk Factors” that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Moreover, we operate in a competitive and rapidly changing environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties, nor can management assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. You should read this Quarterly Report with the understanding that our actual future results may be materially different from what we expect. The forward-looking statements contained in this Quarterly Report are made as of the date of this Quarterly Report, and we do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.

In this Quarterly Report, unless otherwise stated or the context otherwise requires, references to the “Company,” “Kalaris,” “we,” “us,” and “our” refer to Kalaris Therapeutics, Inc. (formerly AlloVir, Inc.) and its consolidated subsidiaries.
References to “Legacy Kalaris” refer to Kalaris Tx, Inc. (formerly Kalaris Therapeutics, Inc.) and references to “AlloVir” refer to AlloVir, Inc. prior to completion of the Merger.

Notes to the Unaudited Condensed Consolidated Financial Statements
1. Nature of the Business
Description of the Business
Kalaris Therapeutics, Inc. (“Kalaris” or “the Company”) is a clinical stage biopharmaceutical company dedicated to the development and commercialization of treatments for prevalent retinal diseases with major unmet medical needs. The Company is developing TH103, a novel, clinical stage anti-vascular endothelial growth factor (“VEGF”) drug, specifically engineered to achieve extended intraocular retention with enhanced VEGF inhibition in patients with exudative and/or neovascular retinal diseases.
On March 18, 2025 (the “Closing Date”), AlloVir, Inc., a Delaware corporation (“AlloVir”), consummated the previously announced merger (the “Merger”) pursuant to the terms of the Agreement and Plan of Merger, dated as of November 7, 2024 (the “Merger Agreement”), by and among AlloVir, Aurora Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of AlloVir (“Merger Sub”) and Kalaris Tx, Inc. (formerly Kalaris Therapeutics, Inc.), a Delaware corporation (“Legacy Kalaris”). At the effective time of the Merger (the “Effective Time”), Merger Sub merged with and into Legacy Kalaris, with Legacy Kalaris continuing as a wholly-owned subsidiary of AlloVir and the surviving corporation of the Merger and, after giving effect to the Merger, Legacy Kalaris became a wholly-owned subsidiary of AlloVir. Immediately following the Effective Time, AlloVir changed its name to “Kalaris Therapeutics, Inc.” At the Effective Time, the Company’s business became primarily the business conducted by Legacy Kalaris.

The Company will need to raise additional financing to continue its product's development for the foreseeable future until it becomes profitable. The Company plans to monitor expenses and raise additional capital through a combination of equity and debt financings, strategic alliances, and licensing arrangements. The Company’s ability to access capital when needed is not assured and, if capital is not available to the Company when, and in the amounts needed, the Company may be required to significantly curtail, delay or discontinue one or more of its research or development programs or the commercialization of any product candidate, or be unable to expand its operations or otherwise capitalize on the Company’s business opportunities, as desired, which could materially harm the Company’s business, financial condition and results of operations.

2. Summary of Significant Accounting Policies
Basis of Presentation
The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). AlloVir and its subsidiaries’ operating results are included in the Company’s condensed consolidated financial statements from the Closing Date of the Merger. All other accompanying financial data as of December 31, 2025, and for the three months ended March 31, 2025, include only the accounts and disclosures of Legacy Kalaris. All intercompany transactions and balances have been eliminated upon consolidation.
These unaudited condensed consolidated financial statements and the notes accompanying them should be read in conjunction with Legacy Kalaris' audited financial statements as of and for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2026.
All historical common share data and per-share amounts prior to the Merger were retrospectively recast to reflect the effect of the exchange ratio of
Unaudited Condensed Financial Statements
The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited annual financial statements and reflect, in the opinion of management, all adjustments of a normal and recurring nature that are necessary for the fair statement of the Company’s financial position as of March 31, 2026 and its results of operations and its cash flows for the three months ended March 31, 2026 and 2025. The results of operations for the three months ended March 31, 2026 and 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2026, or for any other future annual or interim period. The consolidated balance sheet as of December 31, 2025 included herein was derived from the audited financial statements as of that date. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted from these unaudited condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted
ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40)
In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The amendments in this ASU do not change or remove current expense disclosure requirements; however, the amendments affect where such information appears in the notes to the financial statements because entities are required to include certain current disclosures in the same tabular format as the other disaggregation requirements in the amendments. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods

3. Merger with AlloVir
On
Subject to the terms and conditions of the Merger Agreement, at the Effective Time, all issued and outstanding shares of the Legacy Kalaris’ common stock (including common stock issued upon conversion of Legacy Kalaris’ redeemable convertible preferred stock and outstanding convertible promissory notes, other than the AlloVir Note (as defined below)) converted into the right to receive

The Merger was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, Legacy Kalaris was deemed to be the accounting acquirer for financial reporting purposes. This determination was primarily based on the fact that, immediately following the Merger: (1) Legacy Kalaris’ stockholders owned a substantial majority of the voting rights of the Company, inclusive of Samsara; (2) Legacy Kalaris designated a majority of the initial members of the board of directors of the Company; and (3) other than with respect to the Company’s chief financial officer, for which the Company had commenced a search for a qualified candidate, the Company's senior management (which are determined by the board of directors of the Company) held all key positions in senior management of the Company. For accounting purposes, the Merger is treated as the equivalent of Legacy Kalaris issuing stock to acquire the net assets of AlloVir. The reported operating results prior to the Merger are those of Legacy Kalaris. The net assets of AlloVir were recorded at their carrying value in the condensed consolidated financial statements of the Company. Historical common stock share, restricted share awards, common stock options and exercise prices data of Legacy Kalaris have been retroactively recast based on the Exchange Ratio.
AlloVir’s net assets acquired included the following: $

The Company classifies its money market funds and U.S. government treasury securities as Level 1 assets under the fair value hierarchy as these assets have been valued using quoted market prices in active markets without any valuation adjustment. The Company classifies its derivative liabilities and tranche liability as Level 3 liabilities under the fair value hierarchy as these liabilities have been valued using pricing models with unobservable inputs supported by little or no market activity that are significant to the fair value of the liabilities. The carrying amounts of prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate their fair value due to their short-term maturities. During the periods presented, the Company has not changed the manner in which it values liabilities that are measured at estimated fair value using Level 3 inputs. There were no transfers within the hierarchy for any period presented.
The Company issued the following financial instruments to be accounted for at fair value on a recurring basis: derivative liabilities embedded in convertible promissory notes, and the tranche liability related to the convertible note financing (Note 8).
The Company estimated the fair value of the derivative liabilities embedded in the convertible promissory notes using a with-and-without scenario analysis. The Company estimated that the embedded change of control feature fair values were minimal based on the low probability of the change of control events during the three months ended March 31, 2026.
The following assumptions were used to determine the estimated fair value of the derivative liabilities related to the redemption features as of the issuance dates:
|
|
At Issuance Date |
Expected term (in years) |
|
|
Probability of achievement |
|
|

The following assumptions were used to determine the estimated fair value of the derivative liabilities related to the redemption features as of the issuance date and as of December 31, 2024:

|

|
|
||

|
|
As all outstanding convertible promissory notes, other than the AlloVir Note, were converted on March 18, 2025, in connection with the closing of the Merger, the derivative liabilities expired and their fair values were immaterial at the time of conversion.
The fair value of the tranche liability related to the convertible promissory notes issued in October and November 2024 was estimated using the probability weighted model with the following Level 3 input assumptions: the timing of issuing convertible notes and notes conversion, probabilities of conversion scenarios, the estimated fair value of the Company’s shares into which the note was convertible and a discount rate.

Unless earlier converted or repaid in connection with the 2024 Note Qualified Financing or a change in control on or prior to the maturity date, or at any time at Samsara’s option, Samsara could have elected to convert the 2024 Note and any unpaid accrued interest into the Company’s common stock at a conversion price equal to the Series B-2 Stock conversion price then in effect.
The 2024 Note was issued to Samsara at the estimated fair value of $
The 2024 Note contained embedded features that provided Samsara the right to receive cash or a variable number of shares upon a change in control or the completion of a capital raising transaction by the Company. These embedded features were required to be bifurcated and accounted for separately as a compound derivative instrument.

The Company's commitments under its operating leases are described in Note 9.
Research and Development Agreements
The Company enters into various agreements in the ordinary course of business, such as those with suppliers, contract development and manufacturing organizations, clinical research organizations, and other research and development vendors.

Legal Contingencies
The Company, from time to time, may be a party to litigation arising in the ordinary course of business. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount is reasonably estimable, the Company will accrue a liability for the estimated loss.
Litigation Related to the Merger
Two complaints have been filed by purported AlloVir stockholders as individual actions against AlloVir and the members of its board of directors in the Supreme Court of the State of New York, New York County, captioned Keller v. AlloVir, Inc. et al., No. 650989/2025 (N.Y. Sup. Ct. Feb. 20, 2025), and Morgan v. AlloVir, Inc. et al., No. 650965/2025 (N.Y. Sup. Ct. Feb. 19, 2025) (the “Complaints”). The Complaints allege that the proxy statement/prospectus describing the transaction between Legacy Kalaris and AlloVir misrepresented and/or omitted certain purportedly material information, and assert claims for negligent misrepresentation and concealment and negligence under New York common law. The Complaints seek various remedies including, among other things, an order enjoining the consummation of the merger, requiring the defendants to file an amended proxy statement/prospectus, rescinding the merger or granting rescissory damages, and awarding costs, including plaintiff’s attorneys’ fees and experts’ fees, and other relief the court may deem just and proper. AlloVir and Legacy Kalaris deny the allegations in the Complaints and deny that any further disclosure beyond that already contained in the proxy statement/prospectus was required under applicable law. The Company has not recorded any liabilities in connection with the Complaints.
Litigation Related to Legacy Operations of AlloVir
On January 19, 2024, a purported stockholder of AlloVir filed a lawsuit, captioned Zerbato v. AlloVir, Inc. et al., No. 1:24-cv-10152 (D. Mass.) (the “Securities Class Action”), in the U.S. District Court for the District of Massachusetts (the “Court”) against AlloVir and two of its officers purportedly on behalf of a putative class of stockholders. On April 16, 2024, the Court appointed stockholders Harry Levin and Julio Maurice Bueno as lead plaintiffs and their counsel as lead counsel in the action. On June 17, 2024, lead plaintiffs filed their amended complaint. In the amended complaint, lead plaintiffs asserted claims purportedly on behalf of a putative class of stockholders consisting of persons who purchased or otherwise acquired AlloVir securities between January 11, 2023 and December 21, 2023, inclusive. The amended complaint asserted claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and the related regulations, alleging that the defendants made false and misleading statements and omissions to investors relating to AlloVir’s three Phase 3 studies of posoleucel. The complaint sought, among other things, damages,
24
prejudgment and post-judgment interest, and attorneys’ fees, expert fees and other costs. On
On October 21, 2024, a purported AlloVir stockholder filed a derivative lawsuit, captioned Lister v. Brainard et al., No. 1:24-cv-12658 (D. Mass.), in the U.S. District Court for the District of Massachusetts against certain of AlloVir’s officers and directors and naming AlloVir as a nominal defendant. The derivative complaint alleged, purportedly on behalf of AlloVir, violations of Section 14(a) of the Securities Exchange Act of 1934, breach of fiduciary duties, unjust enrichment, waste of corporate assets, gross mismanagement, and abuse of control against the individual defendants and contribution under Sections 10(b) and 21D of the Securities Exchange Act of 1934 against Dr. Brainard and Mr. Sinha. These claims were based on substantially identical allegations as the complaint in the above-listed Securities Class Action. The lawsuit sought, among other things, an award of damages and restitution in favor of AlloVir, certain changes to AlloVir’s corporate governance, and attorneys’ fees and costs. On August 1, 2025, the plaintiff filed a notice voluntarily dismissing the derivative lawsuit without prejudice.

Equity Plans
At the closing of the Merger, the Company assumed the 2019 Plan.
In connection with the Merger, AlloVir’s stockholders approved an amendment to AlloVir's 2020 Stock Option and Grant Plan (as amended, the “2020 Plan” and together with the 2019 Plan, the “Equity Plans”) to increase the number of shares reserved for future issuance under the 2020 Plan, which is subject to an annual increase on January 1 of each year from 2026 and thereafter, such that the number of shares of common stock reserved and available for issuance under the 2020 Plan is cumulatively increased by

Under the Equity Plans, the Company may grant ISOs, nonqualified stock options (“NSO”), restricted stock awards (“RSAs”), restricted stock unit awards and other stock awards to the Company’s employees, officers, non-employee directors, consultants, and advisors. Options to purchase common stock may be granted at a price not less than the fair market value as established by the board of directors in the case of both NSOs and ISOs. Stock option grants under the Equity Plans generally vest over four years. All options expire no later than ten years from the date of grant.

Stock Options
The Company has granted stock options with service-based vesting conditions. Stock options typically vest over four years and have a maximum term of ten years. The Company typically grants stock options to employees and non-employees at exercise prices deemed to be equal to the fair value of the common stock at the time of grant.
The Black-Scholes option pricing model, used to estimate the fair value of stock-based awards, requires the use of the following assumptions:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes thereto appearing elsewhere in this Quarterly Report. This Quarterly Report contains forward-looking statements that involve risks and uncertainties, such as our plans, objectives, expectations, intentions, and beliefs. There are a number of important risks and uncertainties that could cause our actual results to differ materially from those discussed in these forward-looking statements. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section titled “Risk Factors” under Part II, Item 1A of this Quarterly Report and those discussed in our other disclosures and filings. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments that we may make. All historical common share data and per-share amounts prior to the Merger (as defined below) have been retrospectively adjusted to reflect the exchange ratio of 0.2016 per one share, which was determined in accordance with the Merger Agreement (as defined below).
Overview
We are a clinical stage biopharmaceutical company dedicated to the development and commercialization of treatments for prevalent retinal diseases with major unmet medical needs.
We are developing TH103, a novel, clinical stage anti-vascular endothelial growth factor (“VEGF”) drug, specifically engineered to achieve extended intraocular retention with enhanced VEGF inhibition in patients with exudative and/or neovascular retinal diseases. TH103 is a fully humanized recombinant fusion protein, functioning as a “decoy receptor” (a VEGF trap), leveraging salient molecular properties of the human body’s native, highest affinity VEGF receptor 1. In head-to-head preclinical studies, TH103 showed more anti-VEGF activity and longer duration of activity compared to aflibercept, the current global market-leading anti-VEGF agent, which also functions as a decoy receptor VEGF trap but differs from TH103 in key molecular elements. Initial data from our Phase 1a single ascending dose (“SAD”) trial of TH103 in treatment-naïve neovascular Age-related Macular Degeneration (“nAMD”) patients showed that TH103 was generally well tolerated and exhibited improvements on functional and anatomical outcomes at 1-month post-dosing. Preliminary single dose pharmacokinetic data and retreatment results provide evidence that TH103 may offer extended treatment durability after a standard four-dose loading regimen.
We are investigating TH103 as a treatment for patients with nAMD, a leading cause of blindness in the United States and Europe that affect an estimated 1.6 million adults in the United States. We are currently conducting a Phase 1b/2 multiple ascending dose clinical trial of TH103 in patients with nAMD, which is intended to build upon our ongoing Phase 1a single ascending dose clinical trial. The Phase 1b/2 dose-finding trial is designed to evaluate multiple dose levels of TH103 in approximately 60 to 80 nAMD patients. In the trial, patients are expected to receive four initial monthly intravitreal injections of TH103 and assessments are expected to include safety and preliminary efficacy with a primary time point for analysis at one month following the last injection. Patients will then be followed in an extension phase of the study. Following the implementation of additional manufacturing process refinements, new batches of clinical trial material were manufactured and scheduled to be delivered to trial sites in mid-May 2026 for our ongoing Phase 1b/2 multiple ascending dose study, and we are actively screening patients in anticipation of receiving the new batches and resuming dosing. Enrolled patients will receive four monthly loading doses of TH103 at a dose of 1.0 mg followed by dose escalation in subsequent cohorts per protocol. We expect to report preliminary data from the Phase 1b/2 clinical trial in the first half of 2027. Assuming successful completion of the ongoing Phase 1b/2 clinical trial of TH103, and subject to the favorable results from such trial and discussions with regulators, we intend to initiate Phase 3 clinical trials of TH103 for nAMD by year-end 2027. We also plan to expand the development of TH103 beyond nAMD into other prevalent VEGF-mediated retinal diseases, such as Diabetic Macular Edema (“DME”), diabetic retinopathy (“DR”), and Retinal Vein Occlusion (“RVO”).
Since our inception in September 2019, we have devoted substantially all of our resources to organizing and staffing, business planning, raising capital, acquiring technology, establishing our intellectual property portfolio and performing research and development of our product candidate. We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have incurred significant losses and negative cash flows from operations since our inception. Our net losses were $10.9 million and $10.2 million for the three months ended March 31, 2026 and 2025, respectively. Our negative cash flows from operations were $11.6 million and $7.4 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had an accumulated deficit of $170.9 million. To date, we have funded our operations primarily from sales of our redeemable convertible preferred stock, issuances of convertible promissory notes and a simple agreement for future equity (“SAFE”), from cash and cash equivalents of AlloVir, Inc. (“AlloVir”) received in the Merger (as defined below), and from proceeds from the 2025 Private Placement (as defined below).
32
From inception through March 31, 2026, we have received gross proceeds of $67.5 million from sales of redeemable convertible preferred stock, issuances of convertible promissory notes and a SAFE, we received cash and cash equivalents of AlloVir of approximately $102.1 million in the Merger, and we received aggregate gross proceeds of $50.0 million from the 2025 Private Placement.
As of March 31, 2026, we had $104.9 million in cash, cash equivalents and marketable securities. Based on our current operating plans, our management expects that our cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2027. However, management has based these estimates on assumptions that may prove to be wrong, and our operating plans may change as a result of many factors currently unknown to us. In addition, changing circumstances could cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more than currently expected because of circumstances beyond our control. As a result, we could deplete our capital resources sooner than we currently expect.
We expect to continue to incur substantial losses for the foreseeable future, including costs associated with operating as a public company. We do not expect to generate any revenue from commercial product sales unless and until we successfully complete development and obtain regulatory approval for our product candidate. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of our product candidate, which may never occur. We may never achieve or maintain profitability. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations.
We anticipate that our expenses will increase substantially if and as we:
We do not currently own or operate any drug development or manufacturing facilities. We rely on Contract Development and Manufacturing Organizations (“CDMOs”) to help develop and produce TH103 in accordance with the U.S. Food and Drug Administration’s (“FDA”) current Good Manufacturing Practices regulations for use in our clinical trials. We use external contract research organizations (“CROs”) to conduct our preclinical studies and clinical trials.
Given our stage of development, we do not yet have a marketing or sales organization or commercial infrastructure. Accordingly, if we obtain regulatory approval for our product candidate, we also expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution.
33
Because of the numerous risks and uncertainties associated with product development, our management is unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability, if at all. Even if we are able to generate revenue from the sale of our product candidate, we may not achieve or maintain profitability. If we fail to become profitable or are unable to sustain profitability on a continuing basis, we may be unable to continue our operations at planned levels and may be forced to reduce our operations.
Macroeconomic Trends
The disruption and volatility in the global and domestic capital markets resulting from heightened inflation, current and potential tariffs and other trade restrictions, interest rate and currency rate fluctuations, disruptions at government agencies under the U.S. administration (such as workforce reductions or funding cuts), any potential economic slowdown or recession, including trade wars or civil or political unrest (such as the ongoing war between Ukraine and Russia, conflicts in the Middle East, and tension between China and Taiwan) may increase the cost of capital and limit our ability to access capital. These and similar adverse market conditions may negatively impact our business, financial position and results of operations.
Additionally, in the spring of 2025, the U.S. government initiated a series of tariff-related actions against U.S. trading partners. Although several countries have threatened or imposed retaliatory measures in response, the U.S. reached agreements with a number of trading partners. The reciprocal tariffs and the fentanyl tariffs were imposed pursuant to the International Emergency Economic Powers Act, or the IEEPA. These tariffs were found to be unconstitutional by multiple federal courts in the spring and summer of 2025. However, the Trump Administration imposed a new 10% global tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026. Tariff-related actions are likely to remain a prominent part of U.S. economic policy for the foreseeable future, which may introduce uncertainty in international trade, including impacts to the costs of materials and production processes, supply chain stability, and other factors. While we have not experienced, and do not currently expect to experience, any direct impact from these tariffs and retaliatory measures, the full extent of the future impact of these and other threatened measures remains uncertain. We continue to monitor these tariffs and retaliatory measures and their possible effects on our business.
Legacy Kalaris Financing
In October 2024, Kalaris Tx, Inc. (formerly, Kalaris Therapeutics, Inc.), a Delaware corporation (“Legacy Kalaris”) entered into a convertible note purchase agreement with Samsara BioCapital L.P. (“Samsara”) to issue to Samsara and other investors who subsequently joined the agreement up to $25.0 million of convertible promissory notes with a maturity date of May 31, 2025 (the “Convertible Note Financing”). In October and November 2024, Legacy Kalaris received $10.0 million from the initial closings of the Convertible Note Financing. Under the Merger Agreement (as defined below), Legacy Kalaris was permitted to issue additional convertible promissory notes pursuant to the Convertible Note Financing or otherwise to fund its operations prior to the closing of the Merger (as defined below) in an amount not to exceed $15.0 million in the aggregate on a to be converted post-money basis, with up to $7.5 million to be provided by AlloVir and up to $7.5 million to be provided by existing Legacy Kalaris stockholders (the “Additional Permitted Bridge Financing”). In January 2025, as part of the first tranche of the Additional Permitted Bridge Financing, Legacy Kalaris issued a convertible promissory note in an aggregate principal amount of up to $7.5 million to AlloVir (the “AlloVir Note”) under which AlloVir funded a principal amount of $3.75 million, and Legacy Kalaris issued convertible promissory notes in an aggregate principal amount of $3.75 million to existing Legacy Kalaris stockholders. No additional tranches of the convertible notes financing closed prior to the closing of the Merger. Immediately prior to the closing of the Merger, Legacy Kalaris’ outstanding convertible promissory notes held by its existing stockholders were converted into shares of Legacy Kalaris’ common stock or shares of Legacy Kalaris’ Series B-2 redeemable convertible preferred stock (“Series B-2 Preferred Stock”) that were then converted into shares of Legacy Kalaris’ common stock, which, at the effective time of the Merger, were converted into the right to receive shares of AlloVir’s common stock calculated in accordance with the Exchange Ratio (as defined below). Immediately prior to the closing of the Merger, Legacy Kalaris’ outstanding convertible promissory note issued to AlloVir was cancelled.
Merger with AlloVir
On March 18, 2025 (the “Closing Date”), AlloVir consummated the previously announced merger (the “Merger”) pursuant to the terms of the Agreement and Plan of Merger, dated as of November 7, 2024 (the “Merger Agreement”), by and among AlloVir, Aurora Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of AlloVir (“Merger Sub”) and Legacy Kalaris.
In connection with the Merger, at the effective time of the Merger (the “Effective Time”), Merger Sub merged with and into Legacy Kalaris, with Legacy Kalaris continuing as a wholly-owned subsidiary of AlloVir and the surviving corporation of the Merger and, after giving effect to the Merger, Legacy Kalaris became a wholly-owned subsidiary of AlloVir, and immediately following the Effective Time, AlloVir changed its name to “Kalaris Therapeutics, Inc.” At the Effective Time, our business became primarily the business conducted by Legacy Kalaris.
34
Subject to the terms and conditions of the Merger Agreement, at the Effective Time, all issued and outstanding shares of Legacy Kalaris’ common stock (including common stock issued upon conversion of Legacy Kalaris’ preferred stock and outstanding convertible promissory notes) converted into the right to receive 0.2016 shares of AlloVir’s common stock calculated in accordance with an exchange ratio equal to 1:0.2016 (the “Exchange Ratio”). Each award of restricted shares of Legacy Kalaris’ common stock that was unvested and outstanding was converted into and exchanged for the right to receive a number of restricted shares of AlloVir common stock based on the Exchange Ratio. Each outstanding option to purchase shares of Legacy Kalaris’ common stock under Legacy Kalaris’ 2019 Equity Incentive Plan, whether or not vested, was converted into an option to acquire a number of shares of AlloVir’s common stock based on the Exchange Ratio. Exercise prices of assumed options were determined as the product of the exercise price immediately prior to the Effective Time multiplied by the reciprocal of the Exchange Ratio, and rounding up to the nearest whole cent. There were no changes to any other terms of such options or restricted share awards. Immediately following the Merger, stockholders of Legacy Kalaris owned approximately 74.47% of the outstanding common stock of the combined company on a fully diluted basis. The Merger was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States (“GAAP”). Under this method of accounting, Legacy Kalaris was deemed to be the accounting acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Merger was treated as the equivalent of Legacy Kalaris issuing stock to acquire the net assets of AlloVir. As a result of the Merger, the net assets of AlloVir were recorded at their carrying value and our financial statements are consolidated after the Effective Time.
2025 Private Placement
On December 17, 2025, we entered into a securities purchase agreement (the “2025 Securities Purchase Agreement”) with certain institutional investors named therein, pursuant to which, we issued and sold in a private placement (the “2025 Private Placement”), an aggregate of (i) 4,200,000 shares of our common stock at a purchase price of $10.00 per share, and (ii) pre-funded warrants (“Pre-Funded Warrants”) to purchase up to an aggregate of 800,000 shares of our common stock at a purchase price of $9.9999 per Pre-Funded Warrant, which represents the per share purchase price of our common stock less the $0.0001 per share exercise price for each Pre-Funded Warrant. The Pre-Funded Warrants were exercisable at any time after the date of issuance and all of the Pre-Funded Warrants were exercised in full on April 13, 2026. In connection with the closing of the 2025 Private Placement, we received aggregate gross proceeds from the 2025 Private Placement of $50.0 million, before deducting placement agent fees and offering expenses.
At-the-Market Offering
On April 3, 2026, we filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission (the “SEC”), which was declared effective on April 13, 2026 (the “Shelf Registration Statement”). Under the Shelf Registration Statement, we may offer and sell up to $350.0 million of a variety of securities including common stock, preferred stock, debt securities, subscription rights, warrants or units during the three-year period that commenced upon the Shelf Registration Statement becoming effective. In connection with the filing of the Shelf Registration, we entered into a Common Stock Sales Agreement (the “Sales Agreement”) with TD Securities (USA) LLC (“TD Cowen”), pursuant to which we may issue and sell, from time to time, up to an aggregate of $100.0 million of our common stock in an at-the-market equity offering through TD Cowen, as sales agent (the “At-the-Market Offering”). TD Cowen is entitled to receive compensation equal to up to 3.0% of the gross sales price of the shares of common stock sold pursuant to the Sales Agreement. As of March 31, 2026, we had not sold any shares of common stock pursuant to the At-the-Market Offering.
License Agreement with the University of California, San Diego
In April 2021, we entered into a license agreement with UCSD (as amended, the “UCSD Agreement”) pursuant to which we obtained (i) an exclusive license under the patent rights to make, use, sell, offer for sale, and import licensed products and (ii) a non-exclusive license to use the technology with a right to sublicense, each (i) and (ii) related to new anti-VEGF agents and novel long-acting VEGF inhibitors for intraocular neovascularization for the treatment of patients with retinal pathologies. As partial consideration for the license, we agreed to pay UCSD $0.2 million and were obligated to issue shares of our common stock to UCSD equal to 5% of our fully diluted issued and outstanding securities until such time as an aggregate of $5.0 million in gross proceeds from the sale of equity securities had been raised by us. In June 2022, after the closing of the Series A financing, we issued 137,234 shares of our common stock to UCSD. We were also obligated to pay $0.1 million of patent costs incurred prior to the effective date and are required to reimburse future patent expenses incurred by UCSD during the term of the UCSD Agreement. Under the UCSD Agreement, we are required to make annual license maintenance payments of $10,000 during the first four anniversaries and $15,000 on the fifth and every subsequent anniversary of the effective date. We are obligated to pay an aggregate of up to $4.6 million upon the achievement of various development and regulatory milestones and low single-digit royalties on net sales of licensed products. The royalty is payable, on a licensed product-by-licensed product and country-by country basis, until expiration of the last-to-expire issued patent of the applicable licensed product in the country of sale or the manufacture. If we enter into a sublicensing agreement, we are required to pay UCSD a sublicense fee as a percentage of the fair market value of any sublicense fee received that is not earned royalties for each sublicense granted. The sublicense fee percentage ranges from 50% if the applicable sublicense agreement is entered
35
into within one year from the UCSD Agreement effective date and decreases to 10% if the applicable sublicense agreement is entered into after the first dosing of a patient for a phase 2 clinical trial.
In case of a closing of a merger, or sale of at least 50% of our voting stock or the sale by us of all or substantially all of our assets (collectively referred to as “Liquidity Event”), we are obligated to make a one-time cash milestone payment to UCSD ranging from $0.1 million to $1.0 million based on the valuation of our outstanding shares at the Liquidity Event closing date. The Merger did not meet the definition of the Liquidity Event.
The UCSD Agreement is effective until the expiration date of the longest-lived patent rights or last to be abandoned patent or future patent of the licensed products, whichever is later. We can terminate the agreement upon 60 days written notice. UCSD can terminate the agreement in the event of an uncured material breach, such as a failure to make payments due, or to perform or a violation of any other material term of the UCSD Agreement, is not cured by us within 60 days after a breach written notice provided by UCSD.
The acquisition of the license under the UCSD Agreement, including patent rights and know-how, was accounted for as an asset acquisition. As the acquired technology did not have an alternative future use, we recognized the $0.2 million initial cash consideration, $0.1 million patent reimbursement costs incurred prior to the effective date and $0.2 million related to the obligation to issue shares of our common stock as research and development expenses. The obligation to issue shares of common stock included two components, the initial shares obligation and the additional shares obligation. The fair value of the initial shares obligation was estimated as $0.1 million based on the fair value of 55,440 shares of common stock, which represented 5% of the outstanding fully diluted equity at the effective date. As the initial share obligation was indexed to our own stock, it was recorded as additional paid-in capital. The additional shares obligation was accounted for when the next round of financing closed in March 2022. We estimated the fair value of an additional 81,794 shares of common stock as $0.2 million and recognized it as research and development expenses and additional paid-in capital in March 2022.
We recognized $0.03 million and $0.1 million in patent reimbursement costs for the three months ended March 31, 2026 and 2025, respectively. We made a payment of $0.1 million in connection with our achievement of the first development milestone related to the dosing of the first patient in our Phase 1a clinical trial in August 2024. No other milestones were achieved or probable through March 31, 2026 and, therefore, for the three months ended March 31, 2026, no milestone expense was recognized.
Royalty Agreement with Samsara – Related Party
In July 2024, we entered into a royalty agreement (the “Royalty Agreement”) with Samsara. Under the Royalty Agreement, we redeemed 10,080 shares of our common stock issued to Samsara under a founder’s restricted stock purchase agreement in exchange for our agreement to pay Samsara a low single digit percentage tiered royalty on net sales, if any, of our products developed using the technology licensed under the UCSD Agreement. Such royalties are payable on a product-by-product and country-by-country basis until the later of (i) ten years after the first commercial sale of such product in such country and (ii) the expiration of the last-to-expire issued claim of our patents for such product in such country.
We identified two elements in the Royalty Agreement: repurchased shares, and future royalty payments to Samsara. The repurchase of shares was accounted at an estimated fair value of $32,000 as a reduction of common stock and additional paid-in-capital in the consolidated balance sheet and the consolidated statement of redeemable convertible preferred stock and shareholders’ deficit. We recorded $32.1 million as a long-term liability related to the obligation to make royalty payments to Samsara. The fair value of the royalty obligation was estimated using a risk-adjusted net present value model, based on the contractual royalty rates applied to the future net sales forecast, adjusted by the probability of success of product development and discounted to the effective date of the Royalty Agreement. The excess of the royalty liability over the fair value of the redeemed shares of $32.0 million was recorded as a research and development expense.
Once royalty payments to Samsara are deemed probable and estimable, and if such amounts exceed the initially recorded royalty obligation balance, we will impute interest to accrete the liability on a prospective basis based on such estimates. If and when we make royalty payments under the Royalty Agreement, the royalty obligation balance will be reduced. As of March 31, 2026, royalty payments were not probable and estimable and, therefore, for the three months ended March 31, 2026, no interest expense was recognized for the royalty liability.
Financial Operations Overview
Operating Expenses
Our operating expenses consist of research and development expenses and general and administrative expenses.
36
Research and Development Expenses
The largest component of our total operating expenses since inception has been research and development activities, including preclinical development of our product candidate. Research and development costs are expensed as incurred.
37
External research and development costs include:
Internal research and development costs include:
Costs for certain development activities are recognized based on our management’s evaluation of the progress to completion of specific tasks using information and data provided by our vendors and third-party service providers. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such amounts are recognized as an expense when the goods have been delivered or the services have been performed, or when it is no longer expected that the goods will be delivered or the services rendered. Upfront payments under license agreements are expensed upon receipt of the license, and annual maintenance fees under license agreements are expensed in the period in which they are incurred. Milestone payments under license agreements are accrued, with a corresponding expense being recognized, in the period in which the milestone is determined to be probable of achievement and the related amount is reasonably estimable. Research and development expenses incurred from inception relate to the development of our lead product candidate, TH103.
We expect our research and development expenses to increase substantially for the foreseeable future as we advance our product candidate through clinical trials, pursue regulatory approval of our product candidate and expand the indications for our product candidate. The process of conducting the necessary preclinical and clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidate may be affected by a variety of factors, including the timing and progress of clinical development activities, our ability to successfully complete clinical trials with safety, potency and purity profiles that are satisfactory to the FDA or any comparable foreign regulatory authority, our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize, our product candidate; our ability to establish and maintain agreements with third-party manufacturers for clinical supply for our clinical trials and commercial manufacturing, if our product candidate is approved; the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder; our ability to obtain and maintain patent, trade secret and other intellectual property protection and our ability to commercialize products, if and when approved, whether alone or in collaboration with others. We may never receive regulatory approval for our product candidate. As a result of the uncertainties discussed above, our management is unable to determine the duration and completion costs of our research and development activities or if, when and to what extent we will generate revenue from the commercialization and sale of our product candidate, if approved.
General and Administrative Expenses
General and administrative expenses consist of payroll and personnel-related expenses, including salaries, bonuses, employee benefit costs and stock-based compensation expense. General and administrative expenses also include rent expense, insurance, professional fees for legal, consulting, accounting and tax services, as well as allocated overheads, including information technology costs, and other general operating expenses not otherwise classified as research and development expenses.
We anticipate that our general and administrative expenses will increase as a result of increased personnel costs, including salaries, benefits and stock-based compensation expense. We also expect to continue to incur significant expenses associated with being a public company, including personnel costs, expanded infrastructure and higher consulting, legal and accounting services, investor relations costs and director and officer insurance premiums.
38
Change in fair value of tranche liability
Change in fair value of tranche liability represents gains or losses from the remeasurement of tranche liability related to the investors’ rights to receive additional convertible promissory notes in subsequent tranches of the Convertible Note Financing with a predetermined conversion price. The tranche liability was remeasured at fair value at the end of each reporting period until the tranche liability was cancelled in March 2025.
Change in fair value of derivative liabilities
Change in fair value of derivative liabilities represents gains or losses from the remeasurement of the derivative liabilities embedded in the convertible promissory notes issued to Samsara and other investors at the end of each reporting period until settlement or extinguishment. The derivative liabilities expired in connection with the closing of the Merger on the Closing Date.
Interest expense
Interest expense represents non-cash interest expense accrued on issued and previously outstanding convertible promissory notes and amortization of a debt discount on the advances under the convertible promissory note issued to Samsara in March 2024.
Loss on extinguishment and on issuance of convertible promissory notes
Loss on issuance of convertible promissory notes represents the excess fair value of the convertible promissory over the cash proceeds received on the date of issuance. Loss on extinguishment of convertible promissory notes represents the excess fair value of redeemable convertible preferred stock issued over the net carrying value of the convertible promissory notes at the extinguishment date. All outstanding convertible promissory notes, other than the AlloVir Note, were converted into shares of redeemable convertible preferred stock or common stock of Legacy Kalaris immediately prior to the closing of the Merger on March 18, 2025.
Other income, net
Other income, net includes interest income received from money market marketable securities, U.S. government treasury securities, and bank deposits, the amortization of premiums and accretion of discounts on U.S. government treasury securities, and realized and unrealized foreign currency gains (losses).

Research and development expenses increased by $1.5 million, from $6.0 million for the three months ended March 31, 2025, to $7.6 million for the three months ended March 31, 2026.
CDMO, CRO and other third-party preclinical studies, clinical trials and consulting costs increased by $1.4 million as we initiated our Phase 1a clinical trial in TH103 in June 2024 and our Phase 1b/2 clinical trial in the third quarter of 2025. This was primarily driven by an increase of $1.8 million in CRO and other clinical expenses as we opened additional investigational sites and enrolled patients in our clinical program.
Personnel related costs (including stock-based compensation) increased by $0.2 million due to hiring in our research and development organization to support our clinical trials and manufacturing.
General and Administrative Expenses
General and administrative expenses was $4.3 million for each of the three months ended March 31, 2026 and 2025. The immaterial decrease in general and administrative expenses was primarily attributable to a decrease of $1.3 million in directors’ and officers’ insurance due to a $1.5 million charge for directors' and officers' insurance for AlloVir, Inc. (“AlloVir”) following the closing of the Merger, offset by an increase of $0.8 million in personnel related expenses (including stock-based compensation) to support operating as a public company.
Change in fair value of tranche liability
For the three months ended March 31, 2025, we recognized a $0.4 million gain related to the changes in the fair value of tranche liability. The convertible promissory notes issued in the Convertible Note Financing in October and November 2024 and amended in November 2024 included three subsequent tranches for the issuance of convertible promissory notes at the predetermined conversion price that were concluded to be liabilities and are accounted for at fair value until the tranches’ expiration or settlement. In January 2025, as part of the first tranche of the Additional Permitted Bridge Financing, we issued additional convertible promissory notes for $3.75 million and one of three tranches was settled. In March 2025, we and other noteholders entered into an acknowledgment of conversion and termination agreement to cancel all unfunded tranches and the tranche liability expired unexercised.
Change in fair value of derivative liabilities
For the three months ended March 31, 2025, we recognized a $1.2 million gain related to the changes in the fair value of derivative liabilities embedded into convertible promissory notes issued to Samsara and other investors. All outstanding convertible promissory notes, other than the AlloVir Note, were converted into either shares of redeemable convertible preferred stock or common stock and the derivative liability expired in connection with the closing of the Merger on March 18, 2025.
Interest expense
For the three months ended March 31, 2025, we recognized $1.4 million of interest expense, which included the accrued interest and amortization of debt discount related to issued and outstanding convertible promissory notes issued to Samsara and other investors. All outstanding convertible promissory notes, other than the AlloVir Note, were converted into either shares of redeemable convertible preferred stock or common stock and the derivative liability expired in connection with the closing of the Merger on March 18, 2025.
40
Loss on extinguishment and on issuance of convertible promissory notes
For the three months ended March 31, 2025, we recognized $0.2 million of loss on extinguishment and on issuance of convertible promissory notes to Samsara and other investors. All outstanding convertible promissory notes, other than the AlloVir Note, were converted into either shares of redeemable convertible preferred stock or common stock and the derivative liability expired in connection with the closing of the Merger on March 18, 2025.
Other income, net
Other income, net increased by $0.8 million from $0.2 million for the three months ended March 31, 2025 to $1.0 million for the three months ended March 31, 2026. This increase was primarily attributable to interest income received from money market marketable securities and U.S. government treasury securities as a result of our increased cash position following the Merger and the 2025 Private Placement.
Liquidity and Capital Resources
Sources of Liquidity
Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. From inception, we have primarily funded our operations from sales of redeemable convertible preferred stock, issuances of convertible promissory notes and a SAFE, from cash and cash equivalents of AlloVir received in the Merger, and from proceeds from the 2025 Private Placement.
From inception through March 31, 2026, we have received gross proceeds of $67.5 million from sales of redeemable convertible preferred stock, issuances of convertible promissory notes and a SAFE, we received cash and cash equivalents of AlloVir of approximately $102.1 million in the Merger, and we received aggregate gross proceeds of $50.0 million from the 2025 Private Placement. As of March 31, 2026, we had $104.9 million in cash, cash equivalents and marketable securities.
On April 3, 2026, we filed the Shelf Registration Statement with the SEC, which was declared effective on April 13, 2026. Under the Shelf Registration Statement, we may offer and sell up to $350.0 million of a variety of securities including common stock, preferred stock, debt securities, subscription rights, warrants or units during the three-year period that commenced upon the Shelf Registration Statement becoming effective. Pursuant to the Sales Agreement with TD Cowen which we may issue and sell, from time to time, up to an aggregate of $100.0 million of our common stock in the At-the-Market Offering through TD Cowen, as sales agent. As of March 31, 2026, we had capitalized $0.4 million of deferred transaction costs related to the At-the-Market Offering. We have not sold any shares of our common stock pursuant to the At-the-Market Offering.
Funding Requirements
Our primary uses of cash are to fund our operations, which consist primarily of research and development expenditures related to the development of our lead product candidate, TH103, and, to a lesser extent, general and administrative expenditures. We expect to continue to incur significant and increasing expenses for the foreseeable future as we continue to advance TH103, expand our corporate infrastructure, further our research and development initiatives and incur costs associated with the potential commercialization activities. Conducting preclinical testing and clinical trials is a time consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, TH103, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of a product that we do not expect to be commercially available for several years, if ever. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives.
We have incurred significant losses and negative cash flows from operations since our inception. As of March 31, 2026, we had an accumulated deficit of $170.9 million. Based on our current operating plans, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2027. However, we have based these estimates on assumptions that may prove to be wrong, and our operating plans may change as a result of many factors currently unknown to us. In addition, changing circumstances could cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more than currently expected because of circumstances beyond our control. As a result, we could deplete our capital resources sooner than we currently expect.
This forecast of cash resources and planned operations involves risks and uncertainties, and the actual amount of expenses could vary materially as a result of a number of factors. Because of the numerous risks and uncertainties associated with product development, and because the extent to which we may enter into collaborations with third parties for the development of TH103 is unknown, we may incorrectly estimate the timing and amounts of increased capital outlays and operating expenses associated with
41
completing the research and development of TH103. Our future funding requirements will depend on many factors, including, but not limited to, the following:
Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings or debt financings, or potentially other capital sources, such as collaboration or licensing arrangements with third parties or other strategic transactions. There are no assurances that we will be successful in obtaining an adequate level of financing to support our business plans when needed on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration or licensing arrangements with third parties or other strategic transactions, we may have to relinquish rights to our intellectual property, future revenue streams, research programs, or product candidates, or we may have to grant licenses on terms that may not be favorable to us. If we are unable to raise capital as and when needed or on attractive terms, or
42
at all, we may have to significantly delay, reduce or discontinue the development or future commercialization of TH103 or any future product candidate.

Operating Activities
Net cash used in operating activities was $11.6 million and $7.4 million for the three months ended March 31, 2026 and 2025, respectively.
Cash used in operating activities for the three months ended March 31, 2026, was primarily due to a net loss of $10.9 million, offset by non-cash charges of $0.4 million and further offset by net changes in net operating assets and liabilities of $1.1 million. Non-cash charges primarily consist of $0.6 million in stock-based compensation expense and $0.2 million in accretion of discounts on marketable securities. The unfavorable net change in net operating assets and liabilities was primarily due to an increase in other non-current assets of $0.8 million and a decrease in accounts payable of $0.4 million.
Cash used in operating activities for the three months ended March 31, 2025, was primarily due to a net loss of $10.2 million, reduced by non-cash charges of $0.4 million and further reduced by net changes of $2.3 million in the net operating assets and liabilities. Non-cash changes primarily consist of a $0.4 million stock-based compensation expense, a gain of $1.2 million related to the change in fair value of derivative liabilities, a gain of $0.4 million related to the change in fair value of tranche liability, non-cash interest expense of $1.4 million and loss on issuance of convertible promissory notes of $0.2 million. The change in net operating assets and liabilities was primarily due to a decrease in prepaid expenses and other current assets of $1.4 million, an increase in accounts payable of $0.9 million, an increase in accrued research and development expenses of $1.2 million due to the timing of receipt of invoices from vendors, an increase in accrued expenses and other current liabilities of $0.2 million, partially offset by a decrease of $1.4 million in accrued compensation.
Investing Activities
Net cash used in investing activities for the three months ended March 31, 2026 was $50.4 million, which primarily consisted of $70.4 million in purchases of marketable securities offset by $20.0 million in proceeds from maturities of marketable securities. There was no cash used in investing activities for the three months ended March 31, 2025.
Financing Activities
Net cash used in financing activities for the three months ended March 31, 2026 was $1.7 million, which consisted of $1.8 million in payments of issuance costs related to the 2025 Private Placement and deferred transaction costs related to the At-the-Market Offering, offset by $0.1 million in proceeds from the exercise of stock options.
Net cash provided by financing activities for the three months ended March 31, 2025 was $107.3 million, which consisted of $102.1 million of cash and cash equivalents of AlloVir received in the Merger, proceeds from the issuance of a convertible promissory note of $7.5 million, partially offset by payments of transaction costs related to the Merger of $2.3 million.
Contractual and Other Obligations
We enter into contracts in the normal course of business with CDMOs for clinical supply manufacturing, with CROs for clinical trials and with other vendors for preclinical studies, supplies and other products and services for operating purposes. These agreements generally provide for termination at the request of either party generally with less than one-year notice and, therefore, our management believes that non-cancellable obligations under these agreements are not material. We do not currently expect any of these agreements to be terminated and did not have any non-cancellable obligations under these agreements as of March 31, 2026 and December 31, 2025.
We are required to pay certain milestone payments contingent upon the achievement of specific development and regulatory events in accordance with the UCSD Agreement. Refer to Note 7, Significant Agreements, in our condensed consolidated financial statements included elsewhere in this Quarterly Report for additional details. As of March 31, 2026 and December 31, 2025, we recognized $0.1 million and $0.03 million related to the UCSD Agreement in accrued expenses and other current liabilities in the condensed consolidated balance sheets, respectively. Over the life of the agreement through March 31, 2026, development milestones totaling $0.1 million have been achieved and incurred as research and development expenses. We did not achieve any development milestones and did not incur any related milestone expense during the three months ended March 31, 2026. We are required to pay royalties on sales of products developed under the UCSD Agreement. Our product candidate was in development as of March 31, 2026 and December 31, 2025, and no such royalties were due.
We are obligated to pay royalties to Samsara under the Royalty Agreement. Refer to Note 7, Significant Agreements, in our condensed consolidated financial statements included elsewhere in this Quarterly Report for additional details. We recognized an initial royalty liability in the amount of $32.1 million, which was based on its estimated fair value at the effective date of the Royalty
44
Agreement. Once royalty payments to Samsara are deemed probable and estimable, and if such amounts exceed the royalty liability balance, we will impute interest to accrete the royalty liability on a prospective basis based on such estimates. As of March 31, 2026 these royalties were not probable and estimable.
In February 2025, we entered into an operating lease agreement for office space in Berkeley Heights, New Jersey. The lease commenced in September 2025 and is expected to terminate in December 2031. We can extend the lease term twice for an additional three years and can terminate the lease after four years and four months after the lease commencement date with a termination penalty of $0.3 million. Total remaining undiscounted payments under this lease are approximately $2.0 million. In addition to the base rent, we will pay our share of operating expenses and taxes. The lessor provided a tenant improvement allowance of up to $0.4 million, which we fully utilized in 2025.
Recently Issued Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact the financial position, results of operations or cash flows is disclosed in Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report.
Critical Accounting Estimates
Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. On an ongoing basis, management evaluates these estimates and judgments, including, but not limited to, those related to the accrual of research and development expenses, the fair value of royalty obligation, the fair value of convertible promissory notes, the fair value of tranche liability, the fair value of derivative liabilities, the fair value of common stock and preferred stock, and stock-based compensation. These estimates and assumptions are monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates and assumptions could occur in the future. Our management's estimates are based on our historical experience and on various other factors that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from these estimates under different assumptions or conditions.
There have been no material changes to our critical accounting estimates from those described in “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the SEC on March 17, 2026.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
As a smaller reporting company, we are not required to provide the information required by this item.
Item 4. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer (“CEO”), and Chief Accounting Officer (“CAO”) (our principal executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
Based on their evaluation, the CEO and the CAO have concluded that our disclosure controls and procedures were not effective as of March 31, 2026, because of the material weaknesses in our internal control over financial reporting described below.
45
We have identified material weaknesses in our internal control over financial reporting as of December 31, 2025. These material weaknesses have not been fully remediated as of March 31, 2026. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements would not be prevented or detected on a timely basis.
We did not fully maintain components of the Committee of Sponsoring Organizations of the Treadway Commission framework, including elements of the control environment, risk assessment, monitoring activities, information and communication, and control activities components, relating to: (i) our commitment to attract, develop, and retain competent individuals; (ii) identifying, assessing, and communicating appropriate internal control objectives, (iii) identifying and analyzing risks to achieve these objectives; (iv) selecting, developing, and performing ongoing evaluations to ascertain whether the components of internal controls are present and functioning; (v) communicating accurate information internally and externally, including providing information pursuant to objectives, responsibilities, and functions of internal control; (vi) selecting and developing control activities that contribute to the mitigation of risks and support achievement of objectives and (vii) deploying control activities through policies that establish what is expected and procedures that put policies into action.
These material weaknesses could result in a misstatement of substantially all of our accounts or disclosures that would result in a material misstatement of our annual or interim financial statements that would not be prevented or detected.
Remediation Efforts and Plans
Management has taken actions to remediate the deficiencies in our internal controls over financial reporting, including implementing additional processes and controls designed to address the underlying causes of the above-mentioned material weaknesses.
Management’s internal control remediation efforts include the following:
To the extent that we are not able to hire and retain key individuals or are unable to successfully design and implement required controls, the material weaknesses identified may not be remediated and we may be required to record additional adjustments to our financial statements in the future or otherwise not be able to produce timely or accurate financial statements. The material weaknesses will not be considered remediated until management completes the design and implementation of the measures described above, the controls operate for a sufficient period of time, and management has concluded, through testing, that these controls are effective. These remediation measures will be time-consuming and require financial and operational resources. Our failure to implement and maintain effective internal control over financial reporting could result in errors in our financial statements that may lead to a restatement of our financial statements or cause us to fail to meet our reporting obligations.
46
Changes in Internal Control Over Financial Reporting
Except as discussed above under “Remediation Efforts and Plans”, there were no changes in our internal control over financial reporting during the three months ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
Litigation Related to the Merger
Two complaints have been filed by purported AlloVir stockholders as individual actions against AlloVir and the members of its board of directors in the Supreme Court of the State of New York, New York County, captioned Keller v. AlloVir, Inc. et al., No. 650989/2025 (N.Y. Sup. Ct. Feb. 20, 2025), and Morgan v. AlloVir, Inc. et al., No. 650965/2025 (N.Y. Sup. Ct. Feb. 19, 2025) (the “Complaints”). The Complaints allege that the proxy statement/prospectus describing the transaction between Legacy Kalaris and AlloVir misrepresented and/or omitted certain purportedly material information, and assert claims for negligent misrepresentation and concealment and negligence under New York common law. The Complaints seek various remedies including, among other things, an order enjoining the consummation of the merger, requiring the defendants to file an amended proxy statement/prospectus, rescinding the merger or granting rescissory damages, and awarding costs, including plaintiff’s attorneys’ fees and experts’ fees, and other relief the court may deem just and proper. AlloVir and Legacy Kalaris deny the allegations in the Complaints and deny that any further disclosure beyond that already contained in the proxy statement/prospectus was required under applicable law.
Item 1A. Risk Factors.
Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below together with all of the other information contained in this Quarterly Report, including our financial statements and the related notes included in this Quarterly Report, before deciding to invest in our common stock. These risks, some of which have occurred and any of which may occur in the future, can have a material adverse effect on our business, prospects, operating results and financial condition. In such event, the trading price of our common stock could decline and you might lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business, prospects, operating results and financial condition. In addition, references to past events are provided by way of example only and are not intended to be a complete listing or a representation as to whether or not such factors have occurred in the past or their likelihood of occurring in the future.
Risks Related to Our Financial Position and Need for Additional Capital
We have incurred significant losses since our inception. We expect to continue to incur significant expenses and operating losses for the foreseeable future, and may never achieve or maintain profitability.
Since inception, we have incurred significant operating losses. Our net losses were $10.9 million and $10.2 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, we had cash, cash equivalents and marketable securities of $104.9 million and an accumulated deficit of $170.9 million.
We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. To date, we have funded our operations primarily from sales of redeemable convertible preferred stock, issuances of convertible promissory notes and a SAFE, cash and cash equivalents of AlloVir received in the Merger and proceeds from sales of our common stock and pre-funded warrants in a private placement for aggregate gross proceeds of approximately $50.0 million in December 2025 (the “2025 Private Placement”). We have devoted substantially all of our resources to organizing and staffing, business planning, raising capital, acquiring our technology, establishing our intellectual property portfolio and performing research and development of our product candidate. We are in the early stages of development of our lead product candidate, TH103. We received investigational new drug (“IND”) clearance for TH103 for the treatment of patients with neovascular, or wet, age-related macular degeneration (“nAMD”), in June 2024 and, in August 2024, we treated the first patient in our Phase 1a open-label clinical trial to investigate the safety, tolerability, dose range and pharmacokinetic profile or intravitreal injection of TH103 in patients with nAMD. We announced positive initial data from our Phase 1a SAD trial of TH103 in December 2025. We are also conducting a Phase 1b/2 multiple ascending dose, dose-finding study intended to assess safety and efficacy in patients with nAMD receiving four initial monthly loading doses of TH103, which is intended to build upon our ongoing Phase 1a clinical trial and to inform the optimal dose and regimen for potential Phase 3 development. The Phase 1b/2 dose-finding trial is designed to evaluate multiple dose levels of TH103 in approximately 60 to 80 nAMD patients.
We expect to continue to incur significant expenses and operating losses for the foreseeable future, including costs associated with operating as a public company. We anticipate that our expenses will increase substantially if and as we:
48
Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability.
Our expenses could increase beyond our expectations, if, among other things:
Even if we obtain marketing approval for and are successful in commercializing one or more product candidates, we expect to incur substantial additional product development and other expenditures to develop and market additional product candidates or to expand the approved indications of any marketed product. We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue.
We have never generated revenue from product sales and may never achieve or maintain profitability.
We initiated clinical development of our lead product candidate, TH103, in June 2024, and expect that it will be many years, if ever, before we have a product candidate ready for commercialization. To become and remain profitable, we must succeed in completing development of, obtaining marketing approval for and eventually commercializing, one or more products that generate significant revenue. The ability to achieve this success will require us to be effective in a range of challenging activities, including:
We may never succeed in these activities and, even if we do, we may never generate revenues that are significant enough to achieve profitability. Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual
49
basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our product development efforts, diversify our pipeline or even continue our operations.
We are heavily dependent on the success of our lead product candidate, TH103, which will require significant clinical testing before we can seek marketing approval and potentially generate commercial sales. If TH103 does not receive marketing approval or is not successfully commercialized, or if there is significant delay in doing so, our business will be harmed.
We only recently initiated our first clinical trial, have no products that are approved for commercial sale and may never be able to develop marketable products. We expect that a substantial portion of our efforts and expenditures for the foreseeable future will be devoted to TH103. Our business currently depends heavily on the successful development, marketing approval and commercialization of TH103. We cannot be certain that TH103 will achieve success in ongoing or future clinical trials, receive marketing approval or be successfully commercialized.
If we were required to discontinue development of TH103, or if TH103 does not receive marketing approval for one or more of the indications we pursue, fails to achieve significant market acceptance, or fails to receive adequate reimbursement, we may be delayed by many years in our ability to achieve profitability, if ever, and may not be able to generate sufficient revenue to continue our business.
We will need substantial additional funding for our continuing operations. If we are unable to raise capital when needed or on acceptable terms, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.
We expect to devote substantial financial resources to our ongoing and planned activities, particularly as we conduct our ongoing clinical trials of TH103; prepare for future preclinical studies and clinical trials of TH103; prepare for, initiate and conduct preclinical studies and clinical trials of other product candidates we may develop; and potentially seek marketing approval for any of the product candidates we may develop. We expect our expenses to increase substantially over time in connection with our ongoing and planned activities, particularly as we advance our preclinical activities and our ongoing and planned clinical trials. In addition, if we obtain marketing approval for TH103 or any other product candidate we may develop, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise additional capital or obtain adequate funds when needed or on acceptable terms, we may be required to delay, limit, reduce or terminate our product development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. In addition, attempting to secure additional financing may divert the time and attention of our management from day-to-day activities and distract from our product development efforts.
Our future capital requirements will depend on many factors, including:
50
As of March 31, 2026, we had cash, cash equivalents and marketable securities of $104.9 million. Based on our current operating plans, our management expects that our cash, cash equivalents and marketable securities as of March 31, 2026 will be sufficient to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2027. However, we have based these estimates on assumptions that may prove to be wrong, and our operating plans may change as a result of many factors currently unknown to us. In addition, changing circumstances could cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more than currently expected because of circumstances beyond our control. As a result, we could deplete our capital resources sooner than we currently expect. In addition, because the successful development of TH103 or other product candidates that we may pursue is highly uncertain, at this time we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the development of any product candidate. Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. We will not generate commercial revenues unless and until we can achieve sales of products, which we do not anticipate for a number of years, if at all. Accordingly, we will need to obtain substantial additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all, and we may be impacted by the economic climate and market conditions. For example, market volatility resulting from general United States or global economic or market conditions, including related to any health epidemics, pandemics or other contagious outbreaks could also adversely impact our ability to access capital as and when needed. Alternatively, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans.
Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.
Until such time, if ever, as we can generate significant revenues from product sales, we expect to finance our operations through a combination of public or private equity offerings or debt financings, or potentially other capital sources, such as collaboration or licensing arrangements with third parties or other strategic transactions. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our stockholders’. Any debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, selling or licensing our assets, making capital expenditures, declaring dividends or encumbering our assets to secure future indebtedness.
If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed or on terms acceptable to us, we would be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
Legacy Kalaris was incorporated and commenced operations in 2019. We are a clinical stage company with a limited operating history. Our operations to date have been limited to organizing and staffing, business planning, raising capital, acquiring our technology, establishing our intellectual property portfolio and performing research and development of our product candidate. Our prospects must be considered in light of the uncertainties, risks, expenses and difficulties frequently encountered by companies in their early-stages of operations. We have not yet demonstrated our ability to successfully develop any product candidate, obtain marketing approvals, manufacture a commercial scale product or arrange for a third party to do so on our behalf, or conduct sales, marketing and
51
distribution activities necessary for successful product commercialization. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing, obtaining marketing approval for and commercializing products.
In addition, as our business grows, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown obstacles. We will need to transition at some point from a company with a research and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition. As we continue to build our business, we expect our financial condition and operating results to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating performance.
We have identified material weaknesses in our internal control over financial reporting and we may identify additional material weaknesses in the future or fail to maintain an effective system of internal control over financial reporting, which may result in material misstatements of our financial statements.
We have identified material weaknesses in our internal control over financial reporting as of December 31, 2025 which remain unremediated as of March 31, 2026. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements would not be prevented or detected on a timely basis.
We did not fully maintain components of the Committee of Sponsoring Organizations of the Treadway Commission framework, including elements of the control environment, risk assessment, monitoring activities, information and communication, and control activities components, relating to: (i) our commitment to attract, develop, and retain competent individuals; (ii) identifying, assessing, and communicating appropriate objectives, (iii) identifying and analyzing risks to achieve these objectives; (iv) selecting, developing, and performing ongoing evaluations to ascertain whether the components of internal controls are present and functioning; (v) communicating accurate information internally and externally, including providing information pursuant to objectives, responsibilities, and functions of internal control; (vi) selecting and developing control activities that contribute to the mitigation of risks and support achievement of objectives and (vii) deploying control activities through policies that establish what is expected and procedures that put policies into action.
These material weaknesses could result in a misstatement of substantially all of our accounts or disclosures that would result in a material misstatement of our annual or interim financial statements that would not be prevented or detected. We have begun taking measures, and plan to continue to take measures, to remediate these material weaknesses. We actively recruited additional accounting personnel with appropriate experience, certification, education and training. For example, following the closing of the Merger, AlloVir’s Chief Accounting Officer serves as our Chief Accounting Officer, and AlloVir’s Controller serves as our Controller. In addition, in April 2025, we appointed a new member to our board of directors, who was also appointed as chair of the audit committee of the board of directors and was deemed to be an audit committee financial expert by our board of directors. We are in the process of implementing additional measures and risk assessment procedures designed to improve our disclosure controls and procedures and internal control over financial reporting to address the underlying causes of these material weaknesses, including the implementation of appropriate segregation of duties, formalization of accounting policies and controls, and implementation of accounting systems to automate manual processes. We have engaged financial consultants to assist with the implementation of internal controls over financial reporting. To the extent that we are not able to hire and retain such individuals or are unable to successfully design and implement such controls, the material weaknesses identified may not be remediated and management may be required to record additional adjustments to our financial statements in the future or otherwise not be able to produce timely or accurate financial statements. The material weaknesses will not be considered remediated until management completes the design and implementation of the measures described above, the controls operate for a sufficient period of time, and management has concluded, through testing, that these controls are effective. These remediation measures will be time-consuming and require financial and operational resources. If our management concludes that our internal control over financial reporting is not effective, such a determination could adversely affect investor confidence in us and the valuation of our common stock.
While we are implementing measures to remediate the material weaknesses, we cannot predict the success of such measures or the outcome of our assessment of these measures at this time. We can give no assurance that these measures will remediate the deficiencies in internal control over financial reporting or that additional material weaknesses or significant deficiencies in our internal control over financial reporting will not be identified in the future. Our failure to implement and maintain effective internal control over financial reporting could result in errors in our financial statements that may lead to a restatement of our financial statements or cause us to fail to meet our reporting obligations.
52
Our ability to use our net operating loss carryforwards (“NOLs”) and research and development tax credit carryforwards to offset future taxable income may be subject to certain limitations.
We have a history of cumulative losses and we anticipate that we will continue to incur significant losses in the foreseeable future. As a result, we do not know whether or when we will generate taxable income necessary to utilize our NOLs or research and development tax credit carryforwards. As of December 31, 2025, Kalaris had federal and state NOLs of $103.3 million and $46.8 million, respectively, and federal and state research and development tax credit carryforwards totaling $1.7 million and $0.9 million, respectively.
In general, under Section 382 of the Internal Revenue Code of 1986, as amended and corresponding provisions of state law, a corporation that undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a three-year period, is subject to limitations on its ability to utilize its pre-change NOLs and research and development tax credit carryforwards to offset future taxable income. Legacy Kalaris experienced an ownership change in March 2022 related to a redeemable convertible preferred stock financing. Net operating loss of $3.6 million generated prior to the 2022 change in ownership will be permanently limited for California tax purposes. Net federal operating losses are not limited as they can be carried forward indefinitely. We may experience ownership changes in the future (which may be outside our control). As a result, if and to the extent we earn net taxable income, our ability to use our pre-change NOLs and research and development tax credit carryforwards to offset such taxable income may be subject to limitations.
Risks Related to Research and Development of Our Product Candidates
We are early in our development efforts. If we are unable to commercialize TH103 or any product candidate we may develop or experience significant delays in doing so, our business will be materially harmed.
We are early in our development efforts. We received IND clearance for TH103 for the treatment of patients with nAMD in June 2024 and, in August 2024, we treated the first patient in our Phase 1a clinical trial of TH103 for patients with nAMD. In December 2025, we announced positive initial data from our Phase 1a SAD trial of TH103. Our ability to generate revenues from product sales, which we do not expect will occur for many years, if ever, will depend heavily on the successful development, marketing approval and eventual commercialization of TH103 or one or more other product candidates, which may never occur. The success of TH103 and any other product candidate we may develop will depend on many factors, including the following:
53
If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully develop and commercialize TH103 and any other product candidate we may develop, which would materially harm our business. As a company, we have limited experience in clinical development. Any predictions about the future success or viability of TH103 or any product candidates we may develop in the future may not be as accurate as they could be if we had a history of conducting clinical trials.
Drug development involves a lengthy and expensive process, with an uncertain outcome. The results of preclinical studies and early clinical trials may not be predictive of future results. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of TH103 or any other product candidate we may develop.
The risk of failure for TH103 and any other product candidate we may develop is high. It is impossible to predict when or if TH103 or any other product candidate we may develop will prove effective or safe in humans or will receive marketing approval. Before obtaining marketing approval from regulatory authorities for the sale of a product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of such product candidate in humans. Clinical trials may fail to demonstrate that TH103 or any of our other product candidates are safe for humans and effective for indicated uses. Even if the clinical trials are successful, changes in marketing approval policies during the development period, changes in or the enactment or promulgation of additional statutes, regulations or guidance or changes in regulatory review for each submitted product application may cause delays in the approval or rejection of an application for marketing approval.
Before we can commence clinical trials for any product candidate we may develop other than TH103, we must complete extensive preclinical testing and studies, manufacturing process development studies, and analytical development studies that support our planned INDs and other applications to regulatory authorities in the United States or similar applications in other jurisdictions. We cannot be certain of the timely completion or outcome of our preclinical testing and studies and cannot predict if the outcome of our preclinical testing and studies will ultimately support the further development of our current or future product candidates or whether regulatory authorities will accept our proposed clinical programs. In addition, before we can commence clinical trials of TH103 for Diabetic Macular Edema, diabetic retinopathy, and Retinal Vein Occlusion, or any other intraocular indication, we must submit and clear INDs for the applicable indications in the United States or similar applications in other jurisdictions. As a result, we may not be able to submit applications to initiate clinical development of product candidates on the timelines we expect, if at all, and the submission of these applications may not result in regulatory authorities allowing clinical trials to begin. Furthermore, product candidates are subject to continued preclinical safety studies, which may be conducted concurrently with our clinical testing. The outcomes of these safety studies may delay the launch of or enrollment in future clinical trials and could impact our ability to continue to conduct our clinical trials.
Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to the outcome. We cannot guarantee that any of our clinical trials will be conducted as planned or completed on schedule, or at all. A failure of one or more clinical trials can occur at any stage of testing, which may result from a multitude of factors, including, among other things, flaws in study design, dose selection issues, placebo effects, patient enrollment criteria and failure to demonstrate favorable safety or efficacy traits.
Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. Furthermore, the failure of TH103 or any other product candidate we may develop to demonstrate safety and efficacy in any clinical trial could negatively impact the perception of our other product candidates or cause regulatory authorities to require additional testing before approving any of our product candidates.
We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize any product candidates, including:
54
If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive, if there are safety concerns or if we determine that the observed safety or efficacy profile would not be competitive in the marketplace, we may:
Our product development costs will also increase if we experience delays in preclinical studies or clinical trials or in obtaining marketing or other regulatory approvals. We do not know whether any of our preclinical studies or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. We may also determine to change the design or protocol of one or more of our clinical trials, including to add additional patients or arms, which could result in increased costs and expenses or delays. Significant preclinical study or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.
55
We may conduct clinical trials at sites outside the United States. The Food and Drug Administration (the “FDA”) may not accept data from trials conducted in such locations, and the conduct of trials outside the United States could subject us to additional delays and expense.
We may conduct one or more clinical trials at trial sites that are located outside the United States. The acceptance by the FDA or other regulatory authorities of study data from clinical trials conducted outside their jurisdiction may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the sole basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (1) the data are applicable to the United States population and United States medical practice; (2) the trials were performed by clinical investigators of recognized competence and pursuant to Good Clinical Practices (“GCP”) regulations; and (3) the data may be considered valid without the need for an on-site inspection by the FDA, or if the FDA considers such inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means.
In addition, even where the foreign study data are not intended to serve as the sole basis for approval, the FDA will not accept the data as support for an application for marketing approval unless the study is well-designed and well-conducted in accordance with GCP requirements and the FDA is able to validate the data from the study through an onsite inspection if deemed necessary. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time-consuming, and which may result in TH103 or any other product candidate we may develop not receiving approval for commercialization in the applicable jurisdiction.
Conducting clinical trials outside the United States also exposes us to additional risks, including risks associated with:
The results of early-stage clinical trials and preclinical studies may not be predictive of future results. Initial success in clinical trials may not be indicative of results obtained when these trials are completed or in later stage trials.
The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and preliminary or interim results of a clinical trial do not necessarily predict final results. In addition, initial success in clinical trials may not be indicative of results obtained when such trials are completed. In particular, the small number of patients in our ongoing or future early clinical trials may make the results of these trials less predictive of the outcome of later clinical trials. For example, even if successful, the results of our Phase 1b/2 clinical trial of TH103 may not be predictive of the results of further clinical trials of TH103 or any other product candidate we may develop. Our product candidates may also fail to show the desired safety and efficacy in clinical development despite positive results in preclinical studies or having successfully advanced through initial clinical trials.
Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. Our current or future clinical trials may not ultimately be successful or support further clinical development of any of our product candidates and we cannot assure you that any clinical trials that we may conduct will demonstrate consistent or adequate efficacy and safety to support marketing approval. There is a high failure rate for product candidates proceeding through clinical trials. Many companies in the biopharmaceutical industry have suffered significant setbacks in late-stage clinical trials even after achieving promising results in preclinical testing and earlier-stage clinical trials, and we cannot be certain that we will not face similar setbacks. Any such setbacks in our clinical development could materially harm our business and results of operations.
56
Interim and preliminary results from our clinical trials that we announce or publish from time to time may change as more participant data becomes available and are subject to audit and verification procedures, which could result in material changes in the final data.
From time to time, we may announce or publish interim or preliminary results from our clinical trials. Interim results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as participant enrollment continues and more participant data become available. We also make assumptions, estimations, calculations, and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully evaluate all data. Preliminary or interim results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could be material and could significantly harm our reputation and business prospects.
If we experience delays or difficulties in the enrollment of patients in our clinical trials for TH103 or any other product candidate we develop, our receipt of necessary marketing approvals could be delayed or prevented.
Identifying and qualifying patients to participate in our Phase 1a and Phase 1b/2 clinical trials for TH103 and any other product candidate we may develop is critical to our success. Successful and timely completion of clinical trials will require that we enroll a sufficient number of patients who remain in the trial until its conclusion. We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside of the United States. In addition, some of our competitors have ongoing clinical trials for product candidates that treat the same indications as TH103, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates. We cannot predict how successful we will be at enrolling subjects in future clinical trials. Patient enrollment is affected by a variety of other factors, including:
Our inability to locate and enroll a sufficient number of patients for our clinical trials would result in significant delays, could require us to abandon one or more clinical trials altogether and could delay or prevent our receipt of necessary marketing approvals. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, which could cause the value of our business to decline and limit our ability to obtain additional financing.
57
If dose limiting toxicities, serious adverse events, undesirable side effects or unexpected characteristics are identified during the development of TH103 or any other product candidate we may develop, we may need to abandon or limit our further clinical development of those product candidates.
If TH103 or any other product candidate we may develop is associated with dose limiting toxicities, serious adverse events or undesirable side effects in clinical trials or have characteristics that are unexpected in clinical trials or preclinical testing, we may need to abandon development of such product candidate or limit development to more narrow uses or subpopulations in which the dose limiting toxicities, serious adverse events, undesirable side effects or unexpected characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. We have observed cases of intraocular inflammation (“IOI”) in our Phase 1a and Phase 1b/2 clinical trials of TH103. While these cases were generally mild-to-moderate, were not considered dose-limiting, resolved or were resolving following the administration of topical and/or oral steroids, and were believed to be related to retained impurities that are a byproduct of our biologic manufacturing process, if we are unable to refine our manufacturing process or otherwise reduce the cases of IOI experienced by patients who receive TH103, the clinical development and commercial potential of TH103 may be adversely impacted. In pharmaceutical development, many compounds that initially showed promise in early-stage or clinical testing are later found to cause side effects that delay or prevent further development of the compound or decrease the size of the patient population for whom the compound could ultimately be prescribed.
Additionally, if the results of our clinical trials reveal undesirable side effects, we, regulatory authorities or the IRBs at the institutions in which our trials are conducted could suspend or terminate our clinical trials, regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications or we could be forced to materially modify the design of our clinical trials. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete any of our clinical trials or result in potential liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. If we elect or are forced to suspend or terminate any clinical trial of our product candidates, the commercial prospects of such product candidate will be harmed, and our ability to generate revenues from sales of such product candidate will be delayed or eliminated. Any of these occurrences could materially harm our business.
If TH103 or any other product candidate we may develop receives marketing approval and we, or others, later discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, our ability to market the drug could be compromised.
We are currently conducting a Phase 1b/2 clinical trials of TH103 for nAMD. Clinical trials will be conducted in carefully defined subsets of patients who have agreed to enter into clinical trials. Consequently, it is possible that our clinical trials may indicate an apparent positive effect of TH103 that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If TH103 or any other product candidate we may develop receives marketing approval, and we, or others, later discover that they are less effective than previously believed, or cause undesirable side effects, a number of potentially significant negative consequences could result, including:
In particular, we are developing TH103 to be a best-in-class anti-vascular endothelial growth factor (“VEGF”) therapeutic for common retinal neovascular and exudative diseases. Even if TH103 were to receive marketing approval for any such indication, it may fail to demonstrate longer acting and increased VEGF activity that results in improved real-world outcomes for patients. Any of
58
these events could prevent us from achieving or maintaining market acceptance of a particular product candidate, if approved, and could significantly harm our business, financial condition, and results of operations.
We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.
Because we have limited financial and managerial resources, we focus on product candidates that we identify for specific indications. As a result, we may forego or delay the pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. We may curtail, pause, delay or cease development of product candidates at any stage of preclinical or clinical development based on a variety of factors, including our judgments regarding costs or timing of further development, probability of success of clinical development, regulatory requirements, commercial potential, relative benefits and costs and our overall corporate strategy. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on product development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. Failure to allocate resources or capitalize on strategies in a successful manner will have an adverse impact on our business.
Risks Related to the Commercialization of Our Product Candidates
Even if TH103 or any other product candidate we may develop receives marketing approval, we may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success, and the market opportunity for any of our product candidates, if approved, may be smaller than we estimate.
Even if TH103 or any other product candidate we may develop receives marketing approval, we may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. There is already a large and well-established market for anti-VEGF therapies for retinal diseases, and patients may continue to rely on existing FDA approved or off-label therapies. Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may not be successful. If our product candidates do not achieve an adequate level of acceptance, we may not generate significant revenues from product sales and we may not become profitable. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:
59
Our assessment of the potential market opportunity for our product candidates is based on industry and market data it obtained from industry publications, research, surveys and studies conducted by third parties and our analysis of these data, research, surveys and studies. Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information. While we believe these industry publications and third-party research, surveys and studies are reliable, we have not independently verified such data. Our estimates of the potential market opportunities for our product candidates include a number of key assumptions based on our industry knowledge, industry publications and third-party research, surveys and studies, which may be based on a small sample size and fail to accurately reflect market opportunities. While we believe that our internal assumptions are reasonable, no independent source has verified such assumptions. If any of our assumptions or estimates, or these publications, research, surveys or studies prove to be inaccurate, then the actual market for any of our product candidates may be smaller than we expect, and as a result our revenues from product sales may be limited and it may be more difficult for us to achieve or maintain profitability.
If we are unable to establish sales, marketing and distribution capabilities or enter into sales, marketing and distribution agreements with third parties, we may not be successful in commercializing our product candidates if and when they are approved.
We do not have a sales or marketing infrastructure and have no experience as a company in the sale, marketing or distribution of biopharmaceutical products. To achieve commercial success for any product for which we may obtain marketing approval, we will need to establish a sales, marketing and distribution organization, either ourselves or through collaborations or other arrangements with third parties.
We intend to commercialize TH103, if approved, with our own specialty salesforce. There are risks involved with us establishing our own sales, marketing and distribution capabilities. For example, recruiting and training a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. These efforts may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel. In general, the cost of establishing and maintaining a sales and marketing organization may exceed the cost-effectiveness of doing so.
Factors that may inhibit our efforts to commercialize our products on our own include:
If we are unable to establish our own sales, marketing and distribution capabilities and we enter into arrangements with third parties to perform these services, our revenues from product sales and our profitability, if any, are likely to be lower than if we were to market, sell and distribute any products that we develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell, market and distribute our product candidates or may be unable to do so on terms that are acceptable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish sales, marketing and distribution capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates.
60
We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than we do, thus rendering our products non-competitive, obsolete or reducing the size of the market for our products.
The biopharmaceutical industry, and in particular the market for products treating retinal diseases, is characterized by intense investment and competition aimed at rapidly advancing new technologies. Our product candidates are expected to face substantial competition from multiple sources, including large and specialty pharmaceutical and biotechnology companies, academic research institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may emerge in the future within the field of ophthalmology and, furthermore, within the treatment of retinal disease.
We are aware of a number of companies generally pursuing products to treat retinal diseases, including large pharmaceutical companies that have commercialized or are developing treatments for nAMD, such as F. Hoffman La Roche AG (“Roche”), Novartis AG (“Novartis”), Regeneron Pharmaceuticals, Inc. (“Regeneron”), AbbVie Inc. (“AbbVie”) and Eli Lilly and Company (“Lilly”). Roche has received FDA approval for faricimab, ranibizumab and bevacizumab, though bevacizumab is not approved specifically for nAMD; Novartis has received FDA approval for brolucizumab; and Regeneron has received FDA approval for aflibercept and aflibercept HD. AbbVie is currently collaborating with RegenexBio Inc. (“RegenexBio”) to develop ABBV-RGX-314 as a potential gene therapy treatment for nAMD. Merck & Co. is developing MK-3000, a tri-specific antibody, and MK-8748, a bispecific antibody, for DME and nAMD. In December 2025, Lilly completed the acquisition of Adverum Biotechnologies, Inc. (“Adverum”), including its portfolio of investigational gene therapy products such as ixoberogene soroparvovec (ixo-vec), for which Adverum had previously reported results from a Phase 2 clinical trial.
Several companies have received FDA approval for biosimilars to treat nAMD, including: Samsung Bioepis Co., Ltd. and Biogen Inc., which received approval for Byooviz (ranibizumab-nuna), a ranibizumab biosimilar, in September 2021 and Opuviz (aflibercept-yszy) in May 2024; Coherus BioSciences, Inc., which obtained approval for Cimerli (ranibizumab-eqrn), a ranibizumab biosimilar, in August 2022; Formycon AG, which received approval for Ahzantive (aflibercept-mrbb) in June 2024; Sandoz Group AG, which received approval for Enzeevu (aflibercept-abzv) in August 2024; Mylan Laboratories Inc. and Biocon Biologics Limited, which received approval for Yesafili (afliberceptjbvf), an aflibercept biosimilar, in May 2024; and Amgen Inc. (“Amgen”), which received approval for Pavblu (aflibercept-ayyh) in August 2024. Amgen launched and began commercial distribution of Pavblu for retinal diseases in the fourth quarter of 2024, and Outlook Therapeutics, Inc. is developing bevacizumab-vikg, an investigational ophthalmic formulation of bevacizumab as a potential treatment for nAMD. Additional aflibercept biosimilars are expected to enter the market, which may provide new, cost-effective options for the treatment of nAMD, as well as other retinal conditions mediated by VEGF.
Emerging biopharmaceutical companies advancing therapeutic candidates through clinical trials to treat nAMD include 4D Molecular Therapeutics, Inc. (“4D Molecular Therapeutics”), RegenexBio, Eyepoint Pharmaceuticals, Inc. (“Eyepoint Pharmaceuticals”), Ocular Therapeutix, Inc. (“Ocular Therapeutix”), Kodiak Sciences, Inc. (“Kodiak”), and Ollin Biosciences, Inc. (“Ollin”), among others. 4D Molecular Therapeutics and RegenexBio are each advancing anti-VEGF gene therapy candidates to treat nAMD. 4D Molecular Therapeutics’ drug candidate is in an ongoing Phase 3 trial for nAMD and a Phase 1 trial for DME and RegenexBio’s drug candidate is in a pivotal clinical trial for nAMD and a Phase 2 trial for a potential DR treatment. Eyepoint Pharmaceuticals is developing a sustained release, small molecule tyrosine kinase inhibitor, which is currently under evaluation in two ongoing Phase 3 trials for nAMD and two ongoing Phase 3 trials for DME. Ocular Therapeutix is currently conducting two Phase 3 trials of axitinib intravitreal implant, a small molecule tyrosine kinase inhibitor to treat nAMD, which is also being evaluated in a Phase 3 trial for DR. Kodiak is investigating multiple therapeutics in retinal diseases, including tarcocimab, an investigational anti-VEGF therapy, and KSI-501, a bi-specific anti-IL-6/VEGF trap, both of which are being evaluated in a Phase 3 trial in nAMD. Ollin is investigating OLN324, a VEGF/Ang2 bispecific antibody, in DME and nAMD and plans to advance OLN324 into global Phase 3 trials later in 2026. Several other companies are also developing therapies for nAMD, DME, and other retinal diseases in various earlier stages of clinical development.
Many of the companies against which we are competing or against which we may compete in the future, either alone or in combination with their respective strategic partners, have significantly greater financial, technical and human resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, the regulatory approval process, and marketing than we do. These same competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our development programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other marketing approval for their products more rapidly than we may obtain approval for our products, which could result in our competitors establishing a strong market position before we are able to enter the market. In addition, our ability to compete may be affected in
61
many cases by insurers or other third-party payors seeking to encourage the use of generic and/or biosimilar products. There are biosimilar products currently on the market for certain of the indications that we are pursuing, and additional products are expected to become available on a generic basis over the coming years. If our product candidates are approved, we expect that they will be priced at a significant premium over competitive generic products.
Technology in the biopharmaceutical industry has undergone rapid and significant change, and we expect that it will continue to do so. Any products or processes that we develop may become obsolete or uneconomical before we recover any expenses incurred in connection with their development.
Mergers and acquisition activity in the pharmaceutical, biopharmaceutical and biotechnology sector is likely to result in greater resource concentration among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through sizeable collaborative arrangements with established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our business.
We have pursued and may in the future pursue the in-license or acquisition of rights to complementary technologies and product candidates on an opportunistic basis. However, we may be unable to in-license or acquire any additional technologies or product candidates from third parties. The acquisition and licensing of technologies and product candidates is a competitive area, and a number of more established companies also have similar strategies to in-license or acquire technologies and product candidates that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to it. We also may be unable to in-license or acquire the relevant technology or product candidate on terms that would allow us to make an appropriate return on our investment.
Clinical trial and product liability lawsuits against us could divert our resources and could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.
We face an inherent risk of clinical trial and product liability exposure related to the testing of our product candidates in human clinical trials and will face an even greater risk if we commercially sell any products that we may develop. While we currently have no products that have been approved for commercial sale, the ongoing, planned and future use of product candidates by us in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients that use the product, healthcare providers, pharmaceutical companies or others selling such products. On occasion, large judgments have been awarded in class action lawsuits based on products that had unanticipated adverse effects. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:
We may need to increase our insurance coverage as we expands our clinical trials or if we commence commercialization of our product candidates. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. If a successful clinical trial or product liability claim or series of
62
claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired.
Risks Related to Our Dependence on Third Parties
We rely, and expect to continue to rely, on third parties to conduct our clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such trials, which may prevent or delay our ability to seek or obtain marketing approval for or commercialize our product candidates or otherwise harm our business. If we are not able to maintain these third-party relationships or if these arrangements are terminated, we may have to alter our development and commercialization plans and our business could be adversely affected.
We rely, and expect to continue to rely, on third-party clinical research organizations, in addition to other third parties such as research collaboratives, clinical data management organizations, medical institutions and clinical investigators, to conduct our Phase 1a and Phase 1b/2 clinical trials of TH103 and any other clinical trials we conduct. We currently have no plans to independently conduct clinical trials of TH103 or any other product candidate that we may develop. These contract research organizations (“CROs”) and other third parties play a significant role in the conduct and timing of these trials and subsequent collection and analysis of data. These third-party arrangements might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, our product development activities might be delayed.
Our reliance on these third parties for product development activities reduces our control over these activities but does not relieve us of our responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with good clinical practices (“GCPs”) for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities in Europe and other jurisdictions have similar requirements. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs or trial sites fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable, and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We are also required to register ongoing clinical trials and post the results of completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.
If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully develop and commercialize our product candidates. Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned, and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of any marketing application we submit to the FDA. Any such delay or rejection could prevent us from commercializing our product candidates.
If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative third parties or do so on commercially reasonable terms. Switching or adding more CROs, investigators and other third parties involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays can occur, which could materially impact our ability to meet our desired clinical development timelines. Although we plan to carefully manage our relationships with our CROs, investigators and other third parties, we may nonetheless encounter challenges or delays in the future, which could have a material and adverse impact on our business, financial condition and prospects.
Manufacturing biologics is complex, and we may experience manufacturing problems that result in delays in our development or future commercialization programs.
The manufacturing of biologics is complex and difficult and we may experience production issues or interruptions for TH103 or any other product candidate it may develop, including raw material or starting material variability in terms of quality, cell line viability, productivity or stability issues, shortages of any kind, shipping, distribution, storage and supply chain failures, growth media contamination, equipment malfunctions, operator errors, facility contamination, labor problems, natural disasters, disruption in utility services, terrorist activities, or acts of god that are beyond our control or the control of our contract development and manufacturing organizations (“CDMOs”).
63
Given the nature of biologics manufacturing, there is a risk of contamination during manufacturing. Any contamination could materially harm our or our CDMOs’ ability to produce TH103 or any other product candidate it may develop on schedule and could harm our results of operations and cause reputational damage. Some of the raw materials that we require in our manufacturing process are derived from biologic sources. Such raw materials may be difficult to procure and may be subject to contamination or recall.
Problems with the manufacturing process, even minor deviations from the normal process, could result in product defects or manufacturing failures that result in lot failures, product recalls, product liability claims, insufficient inventory or potentially delay progression of our clinical development of TH103 and any other product candidate it may develop. For example, we have observed cases of IOI in our Phase 1a and Phase 1b/2 clinical trials of TH103 that are believed to be related to retained host cell protein impurities that are a byproduct of our biologic manufacturing process. Although we believe we have made progress in reducing the level of host cell protein in our manufactured drug product and were already at levels acceptable to the FDA for an investigational product, we may never succeed in our goal of reducing host cell protein to below levels of detection or in reducing host cell protein to a level that does not result in cases of IOI at clinically relevant dose levels. Moreover, our efforts to improve our manufacturing process to remove host cell proteins has in the past, and may in the future, cause delays in our clinical development program. We have also experienced performance failures at our third-party manufacturers that have resulted in lower drug product production yields than expected, as well as delays.
If we successfully develop TH103 and any other product candidate, we may encounter problems achieving adequate quantities and quality that meet FDA, EMA or other comparable applicable foreign standards or specifications with consistent and acceptable production yields and costs. The ability to scale our manufacturing and maintain the manufacturing process at the same levels of quality and efficiency is yet to be tested. If we or our third-party CDMOs are unable to scale our manufacturing at the same levels of quality and efficiency, we may not be able to supply the required number of doses for clinical trials or commercial supply. A material shortage, contamination or manufacturing failure in the manufacture of TH103 and any other product candidate we may develop or other adverse impact or disruption in the commercial manufacturing or the production of clinical material could materially harm our development timelines and our business, financial condition, results of operations and prospects.
We rely on third-party CDMOs for the manufacture of both drug substance and finished drug product of our product candidates for preclinical and clinical testing and expect to continue to do so for commercialization. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.
We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely, and expect to continue to rely, on third-party CDMOs for both drug substance and finished drug product, as well as for commercial manufacture of any of our product candidates receive marketing approval. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts. We may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:
We or our third-party manufacturers may encounter shortages in the manufacturing of supplies, raw materials or active pharmaceutical ingredients necessary to produce our product candidates in the quantities needed for our clinical trials or, if our product candidates are approved, in sufficient quantities for commercialization or to meet an increase in demand, as a result of capacity constraints or delays or disruptions in the market for the raw materials or active pharmaceutical ingredients, including shortages caused by the purchase of such raw materials or active pharmaceutical ingredients by our competitors or others. We and our third-party manufacturers’ failure to obtain the raw materials or active pharmaceutical ingredients necessary to manufacture sufficient quantities of our product candidates may have a material adverse effect on our business.
Our third-party manufacturers are subject to inspection and approval by regulatory authorities before we can commence the manufacture and sale of any of our product candidates, and thereafter subject to ongoing inspection from time to time. Third-party
64
manufacturers may not be able to comply with current good manufacturing practices (“cGMP”) regulations or similar regulatory requirements outside of the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products.
Our product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. As a result, we may not obtain access to these facilities on a priority basis or at all. There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. If any of our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. Although we believe that there are several potential alternative manufacturers who could manufacture our product candidates, we may incur added costs and delays in identifying and qualifying any such replacement or be unable to reach agreement with an alternative manufacturer.
Our current and anticipated future dependence upon others for the manufacture of our product candidates or products may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.
We currently rely, and may in the future rely, on single-source suppliers for certain materials and components used in the manufacturing of our product candidates.
We currently rely, and may in the future rely, on single-source suppliers for certain materials and components used in the manufacturing of our product candidates. There are, for certain of these materials and components, few, if any, alternative sources of supply and there is limited need for multiple suppliers at this stage of our business. We cannot ensure that these suppliers will remain in business, have sufficient capacity or supply to meet our needs, be able to supply materials to us at costs that are acceptable to us, or that they will not be purchased by one of our competitors or another company that is not interested in continuing to work with us. Our use of single-source suppliers of certain materials and components exposes it to several risks, including disruptions in supply, price increases or late deliveries. Our suppliers may be unable or unwilling to meet our future demands for our clinical trials. Establishing additional or replacement suppliers for these materials and components could take a substantial amount of time and it may be difficult to establish replacement suppliers who meet regulatory requirements. Any disruption in supply from these single-source suppliers could lead to supply delays or interruptions which would materially adversely affect our business, financial condition and results of operations.
We may enter into collaborations with third parties for the research, development and commercialization of certain of our product candidates. If our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates and our business could be adversely affected.
We may enter into third-party collaborators for the research, development and commercialization of certain of our product candidates. Our likely collaborators include large and mid-size pharmaceutical companies and biotechnology companies. Any such arrangements with third parties will likely limit our control over the amount and timing of resources that our collaborators dedicate to the development or commercialization of our product candidates we may seek to develop with them. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities and efforts to successfully perform the functions assigned to them in these arrangements. We cannot predict the success of any collaboration that we enter into.
Collaborations involving our product candidates we may develop pose the following risks to us:
65
If any collaborations that we enter into do not result in the successful development and commercialization of products or if one of our collaborators terminates its agreement with us, we may not receive any future research funding or milestone or royalty payments under the collaboration. If we do not receive the funding we expect under these agreements, or do not receive it in the timeframe in which we expect to receive it, the development of our product candidates could be delayed, and we may need additional resources to develop our product candidates. All of the risks relating to product development, marketing approval and commercialization described herein also apply to the activities of our collaborators.
We may in the future decide to collaborate with biopharmaceutical companies for the development and potential commercialization of any product candidates we may develop. These relationships, or those like them, may require us to incur non-recurring and other charges, increase our near- and long-term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business. In addition, we could face significant competition in seeking appropriate collaborators, and the negotiation process is time-consuming and complex. Our ability to reach a definitive collaboration agreement will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration, and the proposed collaborator’s evaluation of several factors. If we license rights to any product candidates we or our collaborators may develop, we may not be able to realize the benefit of such transactions if it is unable to successfully integrate them with our existing operations and company culture.
66
We may seek to establish additional collaborations. If we are not able to establish or maintain additional collaborations, on commercially reasonable terms, we may have to alter our development and commercialization plans and our business could be adversely affected.
We plan to selectively pursue collaborations with leading biopharmaceutical companies with particular experience, including development and commercial expertise and capabilities. We face significant competition in attracting appropriate collaborators, and a number of more established companies may also be pursuing strategies to license or acquire third-party intellectual property rights that we consider attractive. These established companies may have a competitive advantage over us due to their size, financial resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA or other regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, the terms of any existing collaboration agreements, and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under future license agreements from entering into agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to negotiate, document and execute. In addition, there have been a significant number of recent business combinations among large biopharmaceutical companies that have resulted in a reduced number of potential future collaborators. Any collaboration we may enter into may limit our ability to enter into future agreements on particular terms or covering similar target indications with other potential collaborators.
If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms or at all, we may have to curtail the development of a product candidate, reduce or delay our development program or one or more of our other development programs, delay our potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we expect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market and generate revenue from product sales, which could have an adverse effect on our business, prospects, financial condition and results of operations.
Any acquisitions or in-license transactions that we complete could disrupt our business, cause dilution to our stockholders or reduce our financial resources.
We may enter into transactions to in-license or acquire other businesses, intellectual property, technologies, product candidates or products. If we determine to pursue a particular transaction, we may not be able to complete the transaction on favorable terms, or at all. Any in-licenses or acquisitions we complete may not strengthen our competitive position, and these transactions may be viewed negatively by investors. We may decide to incur debt in connection with an in-license or acquisition or issue our common stock or other equity securities to the stockholders of the target company, which would reduce the percentage ownership of our existing stockholders. We could incur losses resulting from undiscovered liabilities that are not covered by the indemnification it may obtain from the seller. In addition, we may not be able to successfully integrate the acquired personnel, technologies and operations into our existing business in an effective, timely and nondisruptive manner. In-license and acquisition transactions may also divert management attention from day-to-day responsibilities, increase our expenses and reduce our cash available for operations and other uses. We cannot predict the number, timing or size of additional future in-licenses or acquisitions or the effect that any such transactions might have on our operating results.
67
Risks Related to Our Intellectual Property
If we are unable to obtain and maintain sufficient intellectual property protection for our technology, our product candidates, and product candidates we may develop, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors or other third parties could develop and commercialize products similar or identical to ours, and our ability to successfully develop and, if approved, commercialize our product candidates may be adversely affected.
We rely upon a combination of patents, trademarks, trade secret protection, and confidentiality agreements to protect the intellectual property related to our development programs and product candidates. Our success depends in part on our ability to obtain and maintain patent protection in the United States and other countries with respect to TH103 or our other current or future product candidates. If we are unable to obtain or maintain patent protection with respect to TH103 or our other current or future product candidates, and their uses, our business, financial condition, resultant operations and prospects could be materially harmed.
We generally seek to protect our proprietary position by filing patent applications in the United States and abroad related to our development programs, product candidates and novel discoveries that are important to our business, as appropriate. Our pending and future patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents issue from such applications, and then only to the extent the issued claims cover the technology. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technology, nor can there be any assurance that the patents issued will not be infringed, designed around or invalidated by third parties, including generics. The patent prosecution process is expensive and time-consuming, and we may not be able to file, prosecute, enforce or license all necessary or desirable patent applications at a reasonable cost or in a timely manner.
Our patents and patent applications may fail to result in issued patents with claims that adequately protect TH103 and our other current or future product candidates in the United States or in other foreign countries. There is no assurance that all of the potentially relevant prior art relating to our patents and patent applications has been found, which can prevent a patent from issuing from a pending patent application, or be used to invalidate a patent. Even if patents do successfully issue and even if such patents cover TH103 or our other current or future product candidates, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed, invalidated or held unenforceable. Any successful opposition to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any product candidates that we may develop. Further, the scope and coverage of such patents may be so narrow that a third party could successfully design around our patents without materially impacting the therapeutic effectiveness of the resulting drug product. Further, if we encounter delays in regulatory approvals, the period of time during which we could market a product candidate under patent protection could be reduced.
The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our potential future collaborators will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following:
68
The patent prosecution process is also expensive and time-consuming, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patent applications or maintain and/or enforce patents that may issue based on our patent applications, at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. Additionally, recent reforms and changes at government agencies of the United States and those of non-U.S. jurisdictions could increase the uncertainties and costs surrounding the prosecution or maintenance of our patent applications, and the maintenance, enforcement, or defense of our issued patents. For example, the ability of the USPTO and other applicable patent authorities to properly administer their functions is highly dependent on the levels of funding available to the agency and their ability to retain key personnel and fill key leadership appointments, among various factors. Termination of employees or delays in replacing or hiring for key positions could significantly impact the ability of the USPTO and other applicable patent authorities to fulfill their functions and could greatly impact our ability to timely and adequately prosecute or maintain our patent applications, and our ability to timely and adequately maintain, enforce, or defend our issued patents. We may not be able to obtain or maintain patent applications and patents due to the subject matter claimed in such patent applications and patents being in disclosures in the public domain. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, for patent rights that we have or will in license from third parties, we may not have the right to control the preparation, filing, and prosecution of such patent applications, or to maintain the patents, directed to technology that we license from those third parties. We may also require the cooperation of our licensor(s) in order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, any licensed patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by any of our current or future licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property that we in-license, and as a result, our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to prevent competitors from making, using and selling competing products.
If the patent applications we hold or in-license (or will hold or in-license) with respect to our development programs and product candidates fail to issue, if their breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity for TH103 or our other current or future product candidates, it could dissuade other companies from collaborating with us to develop product candidates, and threaten our ability to commercialize TH103 and our other current or future product candidates. Any such outcome could have a materially adverse effect on our business.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been and will continue to be the subject of litigation and new legislation, resulting in court decisions, including Supreme Court decisions, which have increased uncertainties as to the ability to enforce patent rights in the future. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. For example, many countries restrict the patentability of methods of treatment of the human body. Publications in scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot know with certainty whether we were the first to make the inventions claimed in our own patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result of these and other factors, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products.
Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. For example, the Leahy-Smith America Invents Act created new administrative post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings that allow third parties to challenge the validity of issued patents. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the United States Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.
69
Moreover, we may be subject to a third-party pre-issuance submission of prior art to the USPTO or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. The costs of defending patents or enforcing proprietary rights in post-issuance administrative proceedings and litigation can be substantial and the outcome can be uncertain. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.
The issuance of a patent is not conclusive as to inventorship, scope, validity, or enforceability, and our owned and licensed patents and patent applications may be challenged in the courts or patent offices in the United States and abroad. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. An adverse decision in any such challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products. Generally, issued patents are granted a term of 20 years from the earliest claimed non-provisional filing date. In certain instances, patent term can be adjusted to recapture a portion of delay incurred by the USPTO in examining the patent application (patent term adjustment). The scope of patent protection may also be limited.
If we are unable to secure adequate patent protection for our current or future product candidates, we may be open to competition from generic versions of such products. Given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
We cannot be certain that the claims in patents or our pending patent applications directed to TH103 and our other current or future product candidates will be considered patentable by the USPTO, by patent offices in foreign countries, by the courts, or by other relevant authority. One aspect of the determination of patentability of our inventions depends on the scope and content of the “prior art,” information that was or is deemed available to a person of skill in the relevant art prior to the priority date of the claimed invention. There may be prior art of which we are not aware that may affect the patentability of our patent claims or, if issued, affect the validity or enforceability of a patent claim relevant to our business. There is no assurance that there is not prior art of which we are aware, but which we do not believe is relevant to our business, which may, nonetheless, ultimately be found to limit our ability to make, use, sell, offer for sale or import our products that may be approved in the future, or impair our competitive position. Even if the patents do issue based on the patent applications we solely own, co-own, or exclusively license, third parties may challenge the validity, enforceability or scope thereof, which may result in such patents being narrowed, invalidated or held unenforceable. Furthermore, even if they are unchallenged, patents in our portfolio may not adequately exclude third parties from practicing relevant technology or prevent others from designing around our claims. If the breadth or strength of our intellectual property position with respect to our product candidates is threatened, it could dissuade companies from collaborating with us to develop, and threaten our ability to commercialize, our product candidates. In the event of litigation or administrative proceedings, we cannot be certain that the claims in any of our issued patents will be considered valid by courts in the United States or foreign countries.
Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.
We rely on patent, trademark, trade secret and other intellectual property protection in the development, manufacturing and sale of TH103 and our other current and any future product candidates. In particular, patent protection is important in the development and eventual commercialization of TH103 and our other current or any future product candidates. Patents covering TH103 and our other current or any future product candidates normally provide market exclusivity, which is important in order for TH103 and our other current or any future product candidates to become profitable.
Patent rights are of limited duration. In the United States, if all maintenance fees are paid timely, the natural expiration of a patent is generally 20 years after the filing date of the first non-provisional patent application in the patent family. Various extensions may be available, but the life of a patent, and the protection it affords is limited. Given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such product candidates are commercialized. Even if patents covering our product candidates are obtained, once the patent life has expired for a product, we may be open to competition from generic products. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing product candidates similar or identical to ours. Upon issuance in the United States, the term of a patent can be increased by patent term adjustment, which is based on certain delays caused by the
70
USPTO, but this increase can be reduced or eliminated based on certain delays caused by the patent applicant during patent prosecution. The term of a U.S. patent may also be shortened if the patent is terminally disclaimed over an earlier-filed patent.
Depending upon the timing, duration and specifics of FDA marketing approval of TH103 and our other current and future product candidates, one or more of our U.S. patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years beyond the normal expiration of the patent as compensation for patent term lost during drug development and the FDA regulatory review process, which is limited to the approved indication (or any additional indications approved during the period of extension). This extension is based on the first approved use of a product and is limited to only one patent that covers the approved product, the approved use of the product, or a method of manufacturing the product. Such patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval. However, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. We may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time-period or the scope of patent protection afforded could be less than we project or request. If we are unable to extend the expiration date of our existing patents or obtain new patents with longer expiry dates, our competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical data to obtain approval of competing products following our patent expiration and launch their product earlier than might otherwise be the case.
Laws governing analogous patent term extension (“PTE”) in foreign jurisdictions vary widely, as do laws governing the ability to obtain multiple patents from a single patent family. Additionally, we may not receive an extension if we fail to exercise due diligence during the testing phase or regulatory review process, fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. If we are unable to obtain PTE or restoration, or the term of any such extension is less than we project or request, the period during which we will have the right to exclusively market our product will be shortened and our competitors may obtain approval of competing products following our patent expiration and may take advantage of our investment in development and clinical trials by referencing our clinical and preclinical data to launch their product earlier than might otherwise be the case, and our revenue could be reduced, possibly materially.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.
Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or patent applications will be due to be paid to the USPTO and other foreign patent agencies in several stages over the lifetime of our patents and patent applications. The USPTO and various foreign national or international patent agencies require compliance with a number of procedural, documentary, fee payment, and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment or lapse of patent rights include, but are not limited to, failure to timely file national and regional stage patent applications based on our international patent application, failure to respond to official actions within prescribed time limits, non-payment of fees, and failure to properly legalize and submit formal documents. We employ reputable law firms and other professionals to help us comply with these provisions. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If such an event were to occur, it could have a material adverse effect on our business. If we or any of our licensors fail to maintain the patents and patent applications covering TH103 and our other current or any future product candidates, our competitors may be able to enter the market, which would have an adverse effect on our business, financial conditions, results of operations and growth prospects. We do not have granted patents in certain markets and cannot guarantee that we will obtain patent coverage in such markets that cover TH103 and our other current or any future product candidates.
We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might adversely affect our ability to develop and market our products.
TH103 and our other current or any future product candidates may be subject to claims of infringement of the patent rights of third parties. There can be no assurance that our operations do not, or will not in the future, infringe, misappropriate or otherwise violate existing or future third-party patents or other intellectual property rights. Identification of third-party patent rights that may be relevant to our operations is difficult because patent searching is imperfect due to differences in terminology among patents,
71
incomplete databases and the difficulty in assessing the meaning of patent claims. We cannot provide any assurances that third-party patents do not exist which might be enforced against our existing products or current technology, including our research programs, TH103 and our other current or future product candidates, their respective methods of use, and manufacture thereof, and could result in either an injunction prohibiting our manufacture or future sales, or, with respect to our future sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties, which could be significant. We cannot guarantee that any of our patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent and pending application in the United States and abroad that is relevant to or necessary for the commercialization of our current and future product candidates in any jurisdiction.
Numerous U.S. and foreign patents and pending patent applications exist in our market that are owned by third parties. Our competitors in both the United States and abroad, many of which have substantially greater resources and have made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make, use and sell our product candidates. We do not always conduct independent reviews of pending patent applications and patents issued to third parties. Patent applications in the United States and elsewhere are typically published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Certain U.S. applications that will not be filed outside the United States can remain confidential until patents issue. In addition, patent applications in the United States and elsewhere can be pending for many years before issuance, or unintentionally abandoned patents or applications can be revived. Furthermore, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our product candidates or the use of our product candidates. As such, there may be applications of others now pending or recently revived patents of which we are unaware. These patent applications may later result in issued patents, or the revival of previously abandoned patents, that may be infringed by the manufacture, use or sale of our product candidates or will prevent, limit or otherwise interfere with our ability to make, use or sell our product candidates.
The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect, which may negatively impact our ability to market our products. For example, we may incorrectly determine that our product candidates are not covered by a third-party patent or may incorrectly predict whether a third party’s pending application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, and our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our products.
We may become involved in third-party claims of intellectual property infringement, which may delay or prevent the development and commercialization of our current and any future product candidates.
Our commercial success depends in part on our ability to develop, manufacture, market and sell TH103 and our other current and any future product candidates, while avoiding infringement and other violations of the patents and proprietary rights of third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, derivation, and administrative law proceedings, inter partes review, and post-grant review before the USPTO, as well as oppositions and similar processes in foreign jurisdictions. We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights who allege that our product candidates, uses and/or other proprietary technologies infringe their intellectual property rights. Numerous United States and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we and our collaborators are developing product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, and as we gain greater visibility and market exposure as a public company, the risk increases that our product candidates or other business activities may be subject to claims of infringement of the patent and other proprietary rights of third parties. Third parties may assert that we are infringing their patents or employing their proprietary technology without authorization.
Litigation or other legal proceedings relating to intellectual property claims, with or without merit, is unpredictable and generally expensive and time consuming and, even if resolved in our favor, is likely to divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.
72
Also, there may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our current and future product candidates. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our current or future product candidates may infringe.
In addition, third parties may obtain patent rights in the future and claim that use of our technologies infringes upon their rights. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our product candidates, any products formed during the manufacturing process, methods of treating certain diseases or conditions that we are pursuing with our product candidates, our formulations including combination therapies, or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtained a license under the applicable patents, or until such patents expire. Such a license may not be available on commercially reasonable terms or at all. In addition, we may be subject to claims that it is infringing other intellectual property rights, such as trademarks or copyrights, or misappropriating the trade secrets of others, and to the extent that our employees, consultants or contractors use intellectual property or proprietary information owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.
Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize one or more of our current and future product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful infringement or other intellectual property claim against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our affected products, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly. We cannot provide any assurances that third-party patents do not exist which might be enforced against our product candidates, resulting in either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties or other forms of compensation to third parties.
During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing products, programs or intellectual property could be diminished. Accordingly, the market price of shares of our common stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.
We may become involved in lawsuits to protect or enforce our patents or other intellectual property rights, or the patents or other intellectual property rights of any licensors, which could be expensive, time consuming, and unsuccessful, and could result in a court or administrative body finding our patents to be invalid or unenforceable.
Competitors may challenge, infringe, or otherwise violate our patents, the patents of our licensors, or our other intellectual property rights. To counter challenges, infringement, or unauthorized use or misappropriations, we or any licensors may be required to file or defend legal claims, which can be expensive and time-consuming. In addition, in such a proceeding, a court may decide that one or more patents of ours or any of our current or future licensors is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. The initiation of a claim against a third party may also cause the third party to bring counter claims against us such as claims asserting that our patents are invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness (inventive step), non-enablement, insufficient written description, or failure to claim patent-eligible subject matter. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant material information from the USPTO, or made a materially misleading statement, during prosecution. Third parties may also raise similar validity claims before the USPTO in post-grant proceedings such as ex parte reexaminations, inter partes review, or post-grant review, or oppositions or similar proceedings outside the United States, in parallel with litigation or even outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. Additionally, we may be subject to claims of patent infringement during those proceedings, and delays caused by the federal agencies may increase the time period that we are subject to such claims. For example, administrative changes, including reduced staff and budgets experienced by the Patent and Trial Appeal Board, could further delay our ability to timely challenge any such patents. In any patent infringement proceeding, there is a risk that a
73
court will decide that a patent of ours (or of our licensor(s)) is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our (or any licensors’) patent claims do not cover the invention, or decide that the other party’s use of ours (or any licensors’) patented technology falls under the safe harbor to patent infringement under 35 U.S.C. §271(e)(1). An adverse outcome in a litigation or proceeding involving our or any licensors’ patents could limit our ability to assert our own or any licensors’ patents against those parties or other competitors and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. Any of these occurrences could adversely affect our competitive position, and our business, financial condition, results of operations, and prospects. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.
We cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. For any patents and patent applications that we may license from third parties in the future, we may have limited or no right to participate in the defense of such licensed patents against challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our current or future product candidates. Such a loss of patent protection could harm our business.
We may not be able to prevent misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Our business could be harmed if in litigation the prevailing party does not offer us a license on commercially reasonable terms. Any litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.
Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have an adverse effect on the price of our common stock. Moreover, we cannot assure you that it will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.
Because of the expense and uncertainty of litigation, we may not be in a position to enforce our intellectual property rights against third parties.
Because of the expense and uncertainty of litigation, we may conclude that even if a third party is infringing our patents, any patents that may be issued as a result of our future patent applications, or other intellectual property rights, the risk-adjusted cost of bringing and enforcing such a claim or action may be too high or not in the best interest of our company or our stockholders. In such cases, we may decide that the more prudent course of action is to simply monitor the situation or initiate or seek some other non-litigious action or solution.
Changes in United States patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.
As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents relating to TH103 and our other current and any future product candidates. Obtaining, defending, maintaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity and is therefore costly, time consuming and inherently uncertain. Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents, and may diminish our ability to protect our inventions, obtain, maintain, enforce and protect our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of our future owned and licensed patents. The United States has enacted and implemented wide-ranging patent reform legislation. The United States Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on actions by Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have licensed or that we might obtain in the future. Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies that enforce them or changes in
74
how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we have licensed or that we may obtain in the future. For example, the complexity and uncertainty of European patent laws have also increased in recent years. In Europe, a new unitary patent system took effect June 1, 2023, which significantly impacts European patents, including those granted before the introduction of such a system. Under the unitary patent system, European applications have the option, upon grant of a patent, of becoming a Unitary Patent subject to the jurisdiction of the Unitary Patent Court (“UPC”). As the UPC is a relatively new court system, there is limited precedent for the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC have the option of opting out of the jurisdiction of the UPC over the first seven years of the court’s existence and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC will be potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the UPC. We cannot predict with certainty the long-term effects of any potential changes. We may decide to opt out our future European patents from the UPC, but doing so may preclude us from realizing the benefits of the UPC. Moreover, if we do not meet all of the formalities and requirements for opt-out under the UPC, our future European patents could remain under the jurisdiction of the UPC. The UPC provides our competitors with a new forum to centrally revoke our European patents and allow for the possibility of a competitor to obtain a pan-European injunction. Such a loss of patent protection could have a material adverse impact on our business and our ability to commercialize our technology and product candidates due to increased competition and, resultantly, on our business, financial condition, prospects and results of operations.
We may not be able to protect our intellectual property rights throughout the world, which could impair our business.
Patents are of national or regional effect, and filing, prosecuting, and defending patents covering TH103 and our other current and any future product candidates throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States, even in jurisdictions where we do pursue patent protection. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, even in jurisdictions where we do pursue patent protection, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we may have or obtain patent protection, but where patent enforcement is not as strong as that in the United States. These competitors’ products may compete with our products in such jurisdictions and take away our market share where we do not have any issued or licensed patents, and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our intellectual property and proprietary rights generally. In addition, certain jurisdictions do not protect to the same extent (or at all) inventions that constitute new methods of treatment. Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. Furthermore, while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market its product candidates. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate, which may have an adverse effect on our ability to successfully commercialize TH103 and our other current or future product candidates in all of our expected significant foreign markets.
Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. As a result, the patent owner may have limited remedies in certain circumstances, which could materially diminish the value of such patent. If we or any of our licensor(s) are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected. Accordingly, our efforts to protect or enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. Furthermore, while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market its product candidates.
75
Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate, which may have an adverse effect on our ability to successfully commercialize TH103 and our other current or future product candidates in all of our expected significant foreign markets.
Further, the standards applied by the USPTO and foreign patent offices in granting patents are not always applied uniformly or predictably. As such, we do not know the degree of future protection that we will have on our technologies, products and product candidates. While we will endeavor to try to protect our technologies, products and product candidates with intellectual property rights such as patents, as appropriate, the process of obtaining patents is time-consuming, expensive and unpredictable.
Further, geo-political actions in the United States and in foreign countries (such as the Russia and Ukraine conflict) could increase the uncertainties and costs surrounding the prosecution or maintenance of our patent applications or those of any current or future licensors and the maintenance, enforcement or defense of its issued patents or those of any current or future licensors. Accordingly, our competitive position may be impaired, and our business, financial condition, results of operations and prospects may be adversely affected.
Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws within the United States. We may need to share our trade secrets and proprietary know-how with current or future partners, collaborators, contractors and others located in countries at heightened risk of theft of trade secrets, including through direct intrusion by private parties or foreign actors, and those affiliated with or controlled by state actors. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. In addition, some courts inside and outside the United States are sometimes less willing or unwilling to protect trade secrets. If we choose to go to court to stop a third party from using any of our trade secrets, we may incur substantial costs. Even if we are successful, these types of lawsuits may consume our time and other resources. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
In addition to the protection afforded by patents, we may seek to rely on trade secret protection to protect proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our product development processes that involve proprietary know-how, information, or technology that is not covered by our patents. We may not be able to meaningfully protect our trade secrets. Although we require all of our employees to assign their inventions to us, and require all of our employees, consultants, advisors and any third parties who have access our its proprietary know-how, information, or technology to enter into confidentiality agreements, we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed to our competitors or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws within the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, we will not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, operating results, and financial condition.
Because we expect to rely on third parties to manufacture TH103 and our other current and any future product candidates, and we expect to collaborate with third parties on the continuing development of TH103 and our other current and any future product candidates, we must, at times, share trade secrets with them. We also expect to conduct research and development programs that may require us to share trade secrets under the terms of our partnerships or agreements with CROs. We seek to protect our proprietary technology in part by entering into agreements containing confidentiality and use restrictions and obligations, including material transfer agreements, consulting agreements, manufacturing and supply agreements, confidentiality agreements or other similar agreements with our advisors, employees, contractors, CDMOs, CROs, other service providers and consultants prior to disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our trade secrets.
Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by its competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements.
Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have an adverse effect on our business and results of operations.
76
In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors CDMOs, CROs, other service providers and consultants to publish data potentially relating to our trade secrets, although such agreements may contain certain limited publication rights. Despite our efforts to protect our trade secrets, our competitors may discover such trade secrets, either through breach of our agreements with third parties, independent development, or publication of information by any of our third-party collaborators. A competitor’s discovery of our trade secrets would impair our competitive position and have an adverse impact on our business.
Monitoring unauthorized disclosure and detection of unauthorized disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive and time-consuming, and the outcome would be unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. If we choose to go to court to stop a third party from using any of its trade secrets, we may incur substantial costs. These lawsuits may consume our time and other resources even if we are successful. For example, significant elements of our products, including confidential aspects of sample preparation, methods of manufacturing, and related processes and software, are based on unpatented trade secrets. Although we take steps to protect our proprietary information and trade secrets, including through contractual means with our employees and consultants, third parties may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose our technology.
We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of their former employers or other third parties or claims asserting ownership of what we regard as our own intellectual property.
We employ individuals who were previously employed at other biotechnology or pharmaceutical companies, or at research institutions, including our competitors or potential competitors. Although we try to ensure that our employees, consultants, and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals have or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Further, although we seek to protect our ownership of intellectual property rights by ensuring that our agreements with our employees, collaborators, and other third parties with whom we do business include provisions requiring such parties to assign rights in inventions to us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed confidential information of its employees’ former employers or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. An inability to incorporate such technologies or features would harm our business and may prevent us from successfully commercializing our technologies or product candidates. In addition, we may lose personnel as a result of such claims and any such litigation, or the threat thereof, may adversely affect our ability to hire employees or contract with independent contractors. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our technologies or product candidates, which could adversely affect our business, financial condition, results of operations and prospects. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.
In addition, we may also be subject to claims that former employers, consultants or other third parties have an ownership interest in our patents or patent applications as an inventor or co-inventor. The failure to name the proper inventors on a patent application can result in the patents issuing thereon being unenforceable. Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent, conflicting obligations of third parties involved in developing our product candidates or as a result of questions regarding co-ownership of potential joint inventions. Litigation may be necessary to resolve these and other claims challenging inventorship and/or ownership. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. There is no guarantee of success in defending these claims, and if we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such challenges may also result in our inability to develop, manufacture, or commercialize our technologies and product candidates without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future technologies and product candidates. Even if we are successful, litigation could result in substantial cost and be a distraction to our management and other employees. Any of the foregoing could adversely affect our business, financial condition, results of operations, and prospects.
77
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.
We intend to use registered or unregistered trademarks or trade names to brand and market ourselves and our products. Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. During trademark registration proceedings, we may receive rejections of our applications by the USPTO or in other foreign jurisdictions. Although we are given an opportunity to respond to such rejections, we may be unable to overcome them. In addition, in the USPTO and in comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, which may not survive such proceedings.
We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential partners or customers in its markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and trade names by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names. Our efforts to enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely affect our financial condition or results of operations.
In addition, any proprietary name we propose to use with our current or future product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product names, we may be required to expend significant additional resources in an effort to identify a suitable proprietary product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties, and be acceptable to the FDA. Furthermore, in many countries, owning and maintaining a trademark registration may not provide an adequate defense against a subsequent infringement claim asserted by the owner of a senior trademark.
Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:
78
If we fail to comply with our obligations under any license, collaboration or other agreements, such agreements may be terminated, we may be required to pay damages and could lose intellectual property rights that are necessary for developing and protecting our product candidates.
We license rights to current and future product candidates or data from third parties, and may enter into additional licensing agreements in the future. For example, we are party to a purchase and research use agreement relating to the license of a cell line for use in the production of TH103, and we are party to a license agreement pursuant to which we have licensed the intellectual property rights to develop and commercialize TH103. If any licensors fail to prosecute, maintain, enforce, and defend such patents, or lose rights to those patents, the rights we have licensed may be reduced or eliminated, and our right to develop and commercialize future product candidates that may be subject of such licensed rights could be adversely affected. In spite of our efforts, any licensors might conclude that we are in material breach of obligations under our license agreements. If we breach any material obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture, and sell products that are covered by the licensed technology or enable a competitor to gain access to the licensed technology. If such in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, our competitors will have the freedom to seek regulatory approval of, and to market, products identical to our product candidates and the licensors to such in-licenses could prevent us from developing or commercializing product candidates that rely upon the patents or other intellectual property rights which were the subject matter of such terminated agreements. Any of these events could adversely affect our business, financial condition, results of operations, and prospects.
Disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including:
79
If disputes over intellectual property that we license prevent or impair our ability to maintain its licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business.
In addition, certain of our current or future agreements with third parties may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities.
Further, we or our licensor(s) may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of its patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, ownership, claim scope, or requests for patent term adjustments. If such defects are identified in a granted patent, we may reissue the granted patent, which would require us to relinquish the patent, and subject the patent to subsequent reissue patent examination. During reissue examination, there is no guarantee that a similar scope of claim would again be granted or that any claim would be granted at all. In addition, if defects in ownership or assignment of rights are identified, there is no guarantee that we would be able to perfect such ownership or assignment of rights. If our licensor(s) are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on its business.
In addition, even where we have the right to control patent prosecution of patents and patent applications under a license from third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.
Our acquired technologies and current or future licensed technology may be subject to retained rights. Our predecessors or licensors may retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or future licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.
If we are limited in our ability to utilize acquired technologies or current or future licensed technologies, or if we lose our rights to critical acquired or in-licensed technology, we may be unable to successfully develop, out-license, market and sell our products, which could prevent or delay new product introductions. Our business strategy depends on the successful development of acquired technologies, and current or future licensed technology, into commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell our product candidate.
We may not be able to license or acquire new or necessary intellectual property rights or technology from third parties.
Because our development programs may require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire, in-license, or use these third-party proprietary rights. Further, other parties, including our competitors, may have patents and have filed (or will file) patent applications potentially relevant to its business. In order to avoid infringing these patents, we may find it necessary or prudent to obtain licenses to such patents from such parties. The licensing or acquisition of intellectual property rights is a competitive area, and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources, and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third party intellectual property rights on terms that would allow us to make an appropriate return on its investment or at all. No assurance can be given that we will be successful in licensing any additional rights or technologies from third parties. Our inability to license the rights and technologies that we have identified, or that we may in the future identify, could have a material adverse impact on our ability to complete the development of our product candidates or to develop additional product candidates. Even if we were able to obtain a license, it could be non-exclusive, thereby giving its competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. Failure to obtain any necessary rights or licenses may detrimentally affect our planned development of our current or future product candidates could be impacted and costs could increase, extending timelines associated with the development of such other product candidates if we fail to acquire necessary rights or licenses. We may even have to abandon the development of the relevant program or product candidate. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
80
We may enter into license agreements in the future with others to advance our existing or future research or allow commercialization of our existing or future product candidates. These licenses may not provide exclusive rights to use such intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop or commercialize our technology and product candidates in the future. In that event, we may be required to expend significant time and resources to redesign our product candidates, or the methods for manufacturing them, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could harm our business, financial condition, results of operations, and prospects significantly. We cannot provide any assurances that third-party patents do not exist which might be enforced against our current manufacturing methods, product candidates, or future methods or product candidates resulting in either an injunction prohibiting their manufacture or future sales, or, with respect to their future sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties, which could be significant.
Risks Related to Regulatory and Legal Compliance Matters
Even if we complete the necessary preclinical studies and clinical trials for our product candidates, the regulatory approval process is expensive, time-consuming and uncertain and we may not receive approvals for the commercialization of some or all of our product candidates in a timely manner, or at all.
Our long-term success and ability to sustain and grow revenue depends on our ability to continue to successfully develop our product candidates and obtain regulatory approval to market our products both in and outside of the United States. In order to market and sell our products in the European Union and many other jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The FDA and comparable foreign regulatory authorities, whose laws and regulations may differ from country to country, impose substantial requirements on the development of product candidates to become eligible for marketing approval, have substantial discretion in the process, and may refuse to accept any application or may decide that the data are insufficient for approval and require additional preclinical studies, clinical trials or other studies and testing. The time required to obtain approval outside of the United States may differ substantially from that required to obtain FDA approval. For example, in many countries outside of the United States, it is required that the product also be approved for reimbursement before the product can be sold in that country. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside of the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. However, a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries.
The process of obtaining marketing approvals, both in the United States and abroad, is lengthy, expensive and uncertain. It may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information, including manufacturing information, to regulatory authorities for each indication to establish the product candidate’s safety and efficacy.
In addition, changes in or the enactment of additional statutes, promulgation of regulations or issuance of guidance during preclinical or clinical development, or comparable changes in the regulatory review process for each submitted product application, may cause delays in the approval or rejection of an application. For example, in December 2022, with the passage of the Food and Drug Omnibus Reform Act of 2022 (“FDORA”), Congress required sponsors to develop and submit a developmentally appropriate practice (“DAP”) for each Phase 3 clinical trial or any other “pivotal study” of a biological product. These plans are meant to encourage the enrollment of more diverse patient populations in late-stage clinical trials of FDA regulated products. In June 2024, as mandated by FDORA, the FDA issued draft guidance outlining the general requirements for DAPs. Unlike most guidance documents issued by the FDA, the DAP guidance when finalized will have the force of law because FDORA specifically dictates that the form and manner for submission of DAPs are specified in FDA guidance.
On January 27, 2025, in response to an Executive Order issued by President Trump on January 21, 2025, on Diversity, Equity and Inclusion programs, the FDA removed the draft DAP guidance from its website. That action, along with similar actions by the Trump Administration to remove many other healthcare webpages, is currently the subject of ongoing litigation. On July 3, 2025, the U.S. District Court for the District of Columbia ruled that the administration’s actions to remove these webpages, including the draft DAP guidance, is unlawful under the Administrative Procedure Act (the “APA”). The court ordered the restoration of many of these webpages. In late July 2025, the FDA restored the draft DAP guidance to its website with a statement that "information on this page may be modified and/or removed in the future subject to the terms of the court's order and implemented consistent with applicable law." Accordingly, in light of these ongoing actions, there is considerable uncertainty surrounding the draft DAP guidance and how the FDA will consider diversity action plans in connection with its review of marketing applications.

Further, on January 31, 2022, the Clinical Trials Regulation (EU) No 536/2014 became applicable in the European Union and replaced the prior Clinical Trials Directive 2001/20/EC. The new regulation aims at simplifying and streamlining the authorization, conduct and transparency of clinical trials in the European Union. Under the new coordinated procedure for the approval of clinical trials, the sponsor of a clinical trial to be conducted in more than one European Union Member State will only be required to submit a single application for approval. The submission will be made through the Clinical Trials Information System, a new clinical trials portal overseen by the EMA, and available to clinical trial sponsors, competent authorities of the European Union Member States and the public. We have not previously secured authorization to conduct clinical studies in the European Union pursuant to this new regulation and, accordingly, there is a risk that we may be delayed in commencing such studies.
The FDA reviews an application to determine whether there is “substantial evidence” to support a finding of effectiveness for the proposed product for its intended use(s). The FDA has interpreted this evidentiary standard to generally require two adequate and well-controlled clinical trials to establish effectiveness of a new product. In February 2026, the Commissioner of the FDA and the Director of Center for Biologics Evaluation and Research published an editorial in the New England Journal of Medicine in which they declared that, in most cases, the new default requirement for FDA approval of a new product will be one adequate and well-controlled pivotal clinical trial plus confirmatory evidence, rather than two pivotal clinical trials. In determining whether to rely on one trial, the FDA will focus on the single trial’s quality, including magnitude of effect, appropriateness of control arms, endpoint selection, statistical power, blinding, handling of missing data, biological plausibility and alignment with intermediate biomarkers. The FDA has long had authority to approve new products on the basis of one trial plus confirmatory evidence and, in recent years, the FDA has exercised that authority with respect to certain types of products. The FDA now takes the position that this will be the new official default standard for most product candidates. At this point, it is unclear how this new policy will be implemented by the FDA and how, if at all, it will affect our clinical development program.
Moreover, principal investigators for our future clinical trials may serve as scientific advisors or consultants to us and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or a comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable foreign regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates.
The FDA or other regulatory authorities may determine that (1) our product candidates are not safe and effective, are only moderately effective or have undesirable or unintended side effects, toxicities or other characteristics that preclude us obtaining marketing approval or prevent or limit commercial use; (2) the dose used in a clinical trial has not been optimized and require us to conduct additional dose optimization studies; or (3) the comparator arm in a trial is no longer the appropriate comparator due to the evolution of the competitive landscape or subsequent data of the comparator product, even if the FDA or other regulatory authority had previously approved the trial design, and we may be required to amend the trial or we may not receive approval of the indication.
Under the Pediatric Research Equity Act, a Biologics License Application (“BLA”) or supplement to a BLA for certain biological products must contain data to assess the safety and effectiveness of the biological product in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective, unless the sponsor receives a deferral or waiver from the FDA. A deferral may be granted for several reasons, including a finding that the product or therapeutic candidate is ready for approval for use in adults before pediatric trials are complete or that additional safety or effectiveness data needs to be collected before the pediatric trials begin. The applicable legislation in the European Union also requires sponsors to either conduct clinical trials in a pediatric population in accordance with a Pediatric Investigation Plan approved by the Pediatric Committee of the EMA, or to obtain a waiver or deferral from the conduct of these studies by this Committee. For any of our product candidates for which we are seeking regulatory approval in the United States or the European Union, we cannot guarantee that we will be able to obtain a waiver or alternatively complete any required studies and other requirements in a timely manner, or at all, which could result in associated reputational harm and subject us to enforcement action.
In addition, we could be adversely affected by several significant administrative law cases decided by the United States Supreme Court in 2024. In Loper Bright Enterprises v. Raimondo, for example, the court overruled Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., which for 40 years required federal courts to defer to permissible agency interpretations of statutes that are silent or ambiguous on a particular topic. The United States Supreme Court stripped federal agencies of this presumptive deference and held that courts must exercise their independent judgment when deciding whether an agency such as the FDA acted within its statutory authority under the APA. Additionally, in Corner Post, Inc. v. Board of Governors of the Federal Reserve System, the court held that actions to challenge a federal regulation under the APA can be initiated within six years of the date of injury to the plaintiff, rather than the date the rule is finalized. The decision appears to give prospective plaintiffs a personal statute of limitations to challenge longstanding agency regulations. Another decision, Securities and Exchange Commission v. Jarkesy, overturned regulatory
82
agencies’ ability to impose civil penalties in administrative proceedings. These decisions could introduce additional uncertainty into the regulatory process and may result in additional legal challenges to actions taken by federal regulatory agencies, including the FDA and the Centers for Medicare & Medicaid Services (“CMS”) that we rely on. In addition to potential changes to regulations as a result of legal challenges, these decisions may result in increased regulatory uncertainty and delays and other impacts, any of which could adversely impact our business and operations.
Finally, our ability to develop and market new products may be impacted if litigation challenging the FDA’s approval of mifepristone continues. In April 2023, the U.S. District Court for the Northern District of Texas invalidated the approval by the FDA of mifepristone, a drug product which was originally approved in 2000 and whose distribution is governed by various measures adopted under a Risk Evaluation and Mitigation Strategy (“REMS”). The Court of Appeals for the Fifth Circuit declined to order the removal of mifepristone from the market but did hold that plaintiffs were likely to prevail in their claim that changes allowing for expanded access of mifepristone, which the FDA authorized in 2016 and 2021, were arbitrary and capricious. In June 2024, the Supreme Court reversed that decision after unanimously finding that the plaintiffs (anti-abortion doctors and organizations) did not have standing to bring this legal action against the FDA. On October 11, 2024, the Attorneys General of three states filed an amended complaint in the district court in Texas challenging the FDA’s actions. On January 16, 2025, the District Court agreed to allow these states to file an amended complaint and continue to pursue this challenge. Thereafter, on September 30, 2025, the District Court declined to dismiss the case and, instead, transferred it to the federal district court in the Eastern District of Missouri. Depending on the outcome of this litigation, our ability to develop new drug product candidates and to maintain approval of existing drug products could be delayed, undermined or subject to protracted litigation.
The approval of our product candidates for commercial sale could also be delayed, limited or denied or we may be required to conduct additional studies for a number of reasons, including, but not limited to, the following:
Accordingly, we may not be able to submit applications for marketing approvals/authorizations and may not receive necessary approvals to commercialize our products in any market. Any failure, delay or setback in obtaining regulatory approval for our product candidates could materially adversely affect our ability to generate revenue from a particular product candidate, which could result in significant harm to our financial position.
83
Failure to obtain marketing approval in foreign jurisdictions would prevent our medicines from being marketed in such jurisdictions and any of its medicines that are approved for marketing in such jurisdiction will be subject to risk associated with foreign operations.
In order to market and sell our medicines in the European Union and many other foreign jurisdictions, we or our collaborators must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, a product must be approved for reimbursement before the product can be approved for sale in that country. We or our collaborators may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Moreover, approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA.
84
Additionally, we could face heightened risks with respect to obtaining marketing authorization in the United Kingdom as a result of the withdrawal of the United Kingdom from the European Union, commonly referred to as Brexit. The United Kingdom is no longer part of the European Single Market and EU Customs Union. As of January 1, 2025, the Medicines and Healthcare Products Regulatory Agency (the “MHRA”), is responsible for approving all medicinal products destined for the United Kingdom market (i.e., Great Britain and Northern Ireland). On April 28, 2025, the United Kingdom Parliament adopted amendments to improve and strengthen the United Kingdom’s clinical trials regulatory regime; they will take effect on April 28, 2026. These changes were needed since the current United Kingdom requirements are based upon the now-repealed EU Clinical Trials Directive (2001/20/EC), which has been replaced by the European Clinical Trials Regulation (Regulation EU No 536/2014). In anticipation of these new requirements, on October 1, 2025, the MHRA updated its guidance for clinical trials to address, among other things, research transparency requirements for clinical trials, the approvals process, the Research Ethics Committee review of clinical trials, simplified arrangements for consent in clinical trials and pharmacovigilance. Since the United Kingdom left the European Union prior to the date on which the EU Clinical Trials Regulation took effect, the United Kingdom’s legal framework did not benefit from the same revisions as occurred at European Union level.
At the same time, a new international recognition procedure (“IRP”) will apply, which intends to facilitate approval of pharmaceutical products in the United Kingdom. The IRP is open to applicants that have already received an authorization for the same product from one of the MHRA’s specified Reference Regulators (“RRs”). The RRs notably include EMA and regulators in the EU/European Economic Area (“EEA”) member states for approvals in the European Union centralized procedure and mutual recognition procedure as well as the FDA (for product approvals granted in the United States). However, the concrete functioning of the IRP is currently unclear. Any delay in obtaining, or an inability to obtain, any marketing approvals may force us or our collaborators to restrict or delay efforts to seek regulatory approval in the UK for our product candidates, which could significantly and materially harm our business.
In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted. For instance, the European Union pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical Strategy for Europe initiative, launched by the European Commission in November 2020. The European Commission’s proposal for revision of several legislative instruments related to medicinal products (potentially reducing the duration of regulatory data protection, revising the eligibility for expedited pathways, etc.) was published on April 26, 2023. On December 11, 2025, the European Parliament and European Council reached a provisional political agreement on the legislation which is expected to be adopted by mid-2026. Key changes include updating regulatory exclusivity to a new system with eight years of data exclusivity and a reduced market exclusivity period to one year, which can be extended if specific conditions are fulfilled up to a maximum of 11 years. This measure, and others, are expected to be adopted by mid-2026 and, following a transition period of 24 months, will likely take effect in mid-2028.
We expect that we will be subject to additional risks in commercializing any of our product candidates that receive marketing approval outside the United States, including tariffs, trade barriers and regulatory requirements; economic weakness, including inflation, or political instability in particular foreign economies and markets; compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country; and workforce uncertainty in countries where labor unrest is more common than in the United States. In addition, we do not have experience commercializing products outside of the United States and such efforts may depend on our ability to find a suitable collaborator.
Any of our product candidates for which we obtain marketing approval in the future may be subject to post-marketing regulatory requirements and could be subject to post-marketing restrictions or withdrawal from the market, and we may be subject to substantial penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our products following approval.
Once marketing approval has been granted, an approved product and its manufacturer and marketer are subject to ongoing review and extensive regulation. Any of our product candidates for which we obtain marketing clearance or approval in the future, as well as the manufacturing processes, post-approval studies and measures, labeling, advertising and promotional activities for such products, among other things, will be subject to continual requirements of and review by the FDA and other United States and foreign regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, and related compliance requirements such as price reporting, transparency reporting and requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing authorization is granted, it may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including in the case of biological products, the requirement to implement a REMS, which could include requirements for a restricted distribution system.
85
The FDA and comparable foreign regulatory authorities may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a biological product. There are similar potential requirements for medical devices. In addition, manufacturers of approved products and those manufacturers’ facilities are required to comply with extensive requirements by the FDA and comparable foreign regulatory authorities, including ensuring that quality control and manufacturing procedures conform to cGMP regulations, which include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We and our contract manufacturers could be subject to periodic unannounced inspections by the FDA or foreign regulatory authorities to monitor and ensure compliance with cGMPs (and similar foreign requirements) or other regulations.
If the FDA or another regulatory authority discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, such regulatory authorities may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we fail to comply with applicable regulatory requirements, a regulatory authority or enforcement authority may, among other things:
Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may adversely affect our ability to commercialize and generate revenue from its products. If regulatory sanctions are applied or if regulatory approval is withdrawn, our business will be seriously harmed.
Assuming we receive marketing approval for one or more of our product candidates, we and our contract manufacturers will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control. If we are not able to comply with post-approval regulatory requirements, our ability to market any future products could be limited, which could adversely affect our ability to sustain profitability. Further, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.
The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. If we are found or alleged to have improperly promoted off-label uses, it may become subject to significant liability.
The FDA and other United States or foreign agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of biological products to ensure that they are manufactured, marketed and distributed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use, and if we communicate about any of our product candidates for which we receive marketing approval in a way that regulators assert goes beyond their approved indications, we may be subject to warnings or enforcement action for off-label marketing. Alleged violations of the Federal Food, Drug and Cosmetic Act or other statutes, including the False Claims Act (the “FCA”), relating to the promotion and advertising of prescription products may lead to investigations or allegations of violations of federal and state health care fraud and abuse laws and state consumer protection laws.
86
For example, on September 9, 2025, President Trump issued a Memorandum directing the United States Department of Health and Human Services (“HHS”) to “ensure transparency and accuracy in direct-to-consumer prescription drug advertising, including by increasing the amount of information regarding any risks associated with the use of any such prescription drug required to be provided in prescription drug advertisements.” The same day, the FDA declared that it will no longer tolerate what it characterized as “deceptive practices” in prescription drug advertising and that the FDA would “aggressively deploy” its available enforcement tools, with “heightened scrutiny” of fair balance and disclosures in social media promotions. The FDA issued a generic “notice letter” to a substantial number of companies directing such companies to “remove any noncompliant advertising and bring all promotional communications into compliance.” When and if our product candidates are approved, we will need to maintain a robust compliance program and processes designed to ensure that all such advertising activities are performed in a legal and compliant manner and anticipate rule changes at the FDA and possibly other agencies.
In September 2021, the FDA published final regulations which describe the types of evidence that the agency will consider in determining the intended use of a biologic. If we are found to have promoted such off-label uses, we may become subject to significant liability. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The government has also required companies to enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully manage the promotion of our products and any product candidates, if approved, we could become subject to significant liability, which would materially adversely affect our business and financial condition.
Notwithstanding the regulatory restrictions on off-label promotion, the FDA and other regulatory authorities allow companies to engage in truthful, non-misleading, and non-promotional scientific communications concerning their products in certain circumstances. For example, in January 2025, the FDA published final guidance outlining its policies governing the distribution of scientific information to healthcare providers about unapproved uses of approved products. The final guidance calls for such communications to be truthful, non-misleading and scientifically sound and to include all information necessary for healthcare providers to interpret the strengths and weaknesses and validity and utility of the information about the unapproved use of the approved product. If a company engages in such communications consistent with the guidance’s recommendations, the FDA indicated that it will not treat such communications as evidence of unlawful promotion of a new intended use for the approved product.
In addition, under some relatively recent guidance from the FDA and the Pre-Approval Information Exchange Act (“PIE Act”), signed into law as part of the Consolidated Appropriations Act of 2023, companies may also promote information that is consistent with the prescribing information and proactively speak to formulary committee members of payors regarding data for an unapproved drug or unapproved uses of an approved drug. We may engage in these discussions and communicate with healthcare providers, payors and other constituencies in compliance with all applicable laws, regulatory guidance and industry best practices. We will need to carefully navigate the FDA’s various regulations, guidance and policies, along with recently enacted legislation, to ensure compliance with restrictions governing promotion of our products.
If approved, our product candidates that are licensed and regulated as biologics may face competition from biosimilars approved through an abbreviated regulatory pathway.
The Biologics Price Competition and Innovation Act of 2009 (the “BPCIA”) was enacted as part of the Patient Protection and the Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act Health Information Technology for Economic and Clinical Health Act (the “ACA”), to establish an abbreviated pathway for the approval of biosimilar and interchangeable biological products. The regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an approved biologic.
Under the BPCIA, a reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product. In addition, the licensure of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still develop and receive licensure of a competing biologic, so long as its BLA does not rely on the reference product, sponsor’s data or submit the application as a biosimilar application.
We believe that any of the product candidates it develops as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for biosimilar competition sooner than anticipated. Further, the FDA may revise the standards governing approval of biosimilars so as to bring such products to the market more quickly. For example, in October 2025, the FDA issued draft guidance which proposes to eliminate the need for sponsors of biosimilar products to conduct comparative human clinical efficacy studies, allowing them to rely
87
instead on analytical testing to demonstrate product differences from a reference product. In March 2026, the FDA issued another draft guidance with additional recommendations that soften the requirements for licensure of biosimilars.
Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of the reference products in a way that is similar to traditional generic substitution for non-biological products will depend on a number of marketplace and regulatory factors that are still developing. Nonetheless, the approval of a biosimilar to our product candidates would have a material adverse impact on our business due to increased competition and pricing pressure.
Our relationships with healthcare providers, physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse, and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
Healthcare professionals, including but not limited to physicians, nurses, medical directors, hospitals, pharmacies, pharmacy benefit managers, group purchasing organizations, wholesalers, insurers, and all individuals employed by such entities, which we refer to collectively as HCPs, may influence the recommendation and prescription of our approved products. Our arrangements with HCPs and others who have the ability to improperly influence the recommendation and prescription of its products may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our approved products. Restrictions under applicable federal, state and foreign healthcare laws and regulations include the following:
Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the laws described above or any other government regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, imprisonment and the curtailment or restructuring of its operations, any of which could adversely affect our business, financial condition, results of operations and prospects.
88
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Liabilities they incur pursuant to these laws could result in significant costs or an interruption in operations, which could have a material adverse effect on our business, financial condition, results of operations and prospects.
Disruptions at the FDA and other government agencies from funding cuts, personnel losses, regulatory reform, government shutdowns and other developments could hinder our ability to obtain guidance from the FDA regarding our clinical development program and develop and secure approval of our product candidates in a timely manner, which would negatively impact our business.
The FDA and comparable regulatory agencies in foreign jurisdictions, such as the EMA and the Committee for Medicinal Products for Human Use (“CHMP”), play a vital role in the development of our product candidates by providing guidance on our clinical development programs and reviewing and approving our regulatory submissions, including INDs, requests for special designations and marketing applications. If these oversight and review activities are disrupted or delayed, then correspondingly our ability to develop and secure timely approval of our product candidates could be impacted in a negative manner.
For example, the loss and retirement of FDA leadership and personnel could lead to disruptions and delays in FDA guidance, review and approval of our product candidate. Pursuant to President Trump's E.O. 14210, “Implementing the President’s ‘Department of Government Efficiency’ Workforce Optimization Initiative,” the Secretary of HHS announced on March 27, 2025, a reorganization and reduction in force across the Department of approximately 20,000 employees (82,000 to 62,000), with FDA’s workforce of approximately 20,000 to decrease by 3,500 full-time employees. Subsequently, the FDA indicated that roughly a quarter of those employees who received RIF notices had been reinstated. On July 14, 2025, following litigation reaching the U.S. Supreme Court, the administration began to carry out these layoffs across HHS, including the FDA. In November 2025, a Congressional Continuing Resolution ended the government shutdown, providing full-year funding of the FDA through the 2026 federal fiscal year at approximately $7 billion with a slight increase in user fees for drug and device companies.
While the FDA’s review of marketing applications and other activities for new drugs and biologics is largely funded through the user fee program established under the Prescription Drug User Fee Act (“PDUFA”), it remains unclear how the administration’s FDA reduction in force and budget cuts will impact this program and the ability of the FDA to provide guidance and review our product candidate in a timely manner. For example, while the FDA reduction in force did not reportedly specifically target FDA reviewers, many operations, administrative and policy staff that help support such reviews were affected and those losses could lead to delays in PDUFA reviews and related activities. There have been several reports in which the FDA failed to meet a PDUFA goal date for approval of an NDA or BLA due to heavy workload and limited resources. In addition, while currently unclear, there is a risk that the FDA reduction in force and budget cutbacks could threaten the integrity of the PDUFA program itself. That is because, for the FDA to obligate user fees collected under PDUFA in the first place, a certain amount of non-user fee appropriations must be spent on the process for the review of applications plus certain other costs during the same fiscal year.
There is also substantial uncertainty as to how regulatory reform measures being implemented by the Trump Administration across the government will impact the FDA and other federal agencies with jurisdiction over our activities. For example, since taking office, the President has issued a number of executive orders that could have a significant impact on the manner in which the FDA conducts its operations and engages in regulatory and oversight activities. These include E.O. 14192, “Unleashing Prosperity Through Deregulation,” January 31, 2025; E.O. 14212, “Establishing the President’s Make America Healthy Again Commission,” February 13, 2025; and E.O. 14219, Ensuring Lawful Governance and Implementing the President’s ‘Department of Government Efficiency” Deregulatory Initiative,” February 21, 2025. If these or other orders or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.
Similarly, actions by the U.S. government have significantly disrupted the operations of U.S. government agencies such as the National Institutes of Health, National Science Foundation, Centers for Disease Control and Prevention, and FDA, which have traditionally provided funding for basic research, research and development, and clinical testing. These U.S. government actions have included, among other things, suspending, terminating and withholding of disbursements of funds owed under ongoing contracts, grants, and other financial assistance agreements; declining to continue multi-year research projects for additional annual budget periods; canceling or delaying solicitations for new contract, grant and other financial assistance awards; canceling or delaying proposal evaluation processes and issuance of such new awards; substantially reducing federal agency staff responsible for managing
89
contract and financial assistance programs; eliminating agency information and resources for facilitating research activity; delaying or terminating federal agency procedures for authorizing international transactions; initiating aggressive enforcement actions that may disrupt the operations of major research universities that are significant contributors to life sciences research in the U.S., and threatening access to federal agency contracts and other funding awards based on companies’ otherwise lawful corporate policies and choice of counsel. These U.S. government actions could, directly or indirectly, significantly disrupt, delay, prevent, or increase the costs of our research and product commercialization programs, including our ability to develop new product candidates, conduct clinical trials, implement research collaborations with other companies or institutions, and obtain approvals to market and sell new products.
In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. During the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions and could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
For example, the federal government shut down on October 1, 2025, and reopened on November 13, 2025. At the outset of that shutdown, the FDA issued a public notice stating that FDA operations would continue to the extent permitted by law, such as activities necessary to address imminent threats to the safety of human life and activities funded by carryover user fee funds. The FDA declared that, during the shutdown period, it does not have legal authority to accept user fees assessed for fiscal year 2026 until a fiscal year 2026 appropriation or Continuing Resolution for the FDA is enacted. As a result, during the government shutdown, the FDA did not accept any regulatory submissions for fiscal year 2026 that require a fee payment. In addition, the FDA indicated that some of its regulatory science research, crucial for advancing product innovation, safety, and quality, would be curtailed during the lapse period.
At the same time, disruptions at the FDA and other government agencies may result from public health events similar to the COVID-19 pandemic. For example, during the pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. In the event of a similar public health emergency in the future, the FDA may not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the United States facing similar circumstances may adopt similar restrictions or other policy measures in response to a similar public health emergency and may also experience delays in their regulatory activities.
Accordingly, if any of the foregoing developments and others impact the ability of the FDA to provide us with guidance regarding our clinical development programs or delay the agency’s review and processing of our regulatory submissions, including INDs, New Drug Applications and BLAs, our business would be negatively impacted. Further, any future government shutdown could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
Recently enacted and future legislation may increase the difficulty and cost for us to commercialize our product candidates, if approved, and affect the prices we may obtain.
In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, restrict or regulate post-approval activities and affect our ability to profitably sell or commercialize any product candidate for which we obtain marketing approval. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we, or any collaborators, may receive for any approved products. If reimbursement of our products is unavailable or limited in scope, our business could be materially harmed.
In March 2010, the ACA was enacted. The ACA established an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents; extended manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; expanded eligibility criteria for Medicaid programs; expanded the entities eligible for discounts under the 340B pricing program; increased the statutory minimum rebates a manufacturer must pay under the Medicaid Rebate Program; established a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare & Medicaid Innovation at the CMS, an agency within HHS, to test innovative payment and service delivery models to lower Medicare and Medicaid spending.
90
Since its enactment, there have been executive, judicial, and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the United States Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results. During the first Trump Administration, the Congress and administration sought to overturn the ACA and related measures. Shortly after taking office in January 2025, President Trump revoked numerous executive orders issued by President Biden, including at least two executive orders (e.g., EO 14009, Strengthening Medicaid and the Affordable Care Act, and EO 14070, Continuing to Strengthen Americans’ Access to Affordable, Quality Health Coverage) where were designed to further implement the ACA. We anticipate similar efforts to undermine the ACA, and the accompanying uncertainty, for the foreseeable future.
In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least US$1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes included aggregate reductions to Medicare payments to providers, which went into effect in April 2013 and will remain in effect through 2032. The American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Further, with the passage of the Inflation Reduction Act (the “IRA”) in August 2022, Congress extended the expansion of ACA premium tax credits through 2025.
These and other laws may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our products or product candidates for which we may obtain regulatory approval or the frequency with which any such product is prescribed or used. For example, on March 11, 2021, the American Rescue Plan Act of 2021 was signed into law, which eliminates the statutory cap on the Medicaid drug rebate, beginning January 1, 2024. The rebate was previously capped at 100% of a product’s average manufacturer price.
In the European Union, on December 13, 2021, Regulation No 2021/2282 on Health Technology Assessment (“HTA”), amending Directive 2011/24/EU, was adopted. While the Regulation entered into force in January 2022, it will only begin to apply from January 2025 onwards, with preparatory and implementation-related steps to take place in the interim. Once applicable, it will have a phased implementation depending on the concerned products. The Regulation intends to boost cooperation among European Union Member States in assessing health technologies, including new medicinal products as well as certain high-risk medical devices, and provide the basis for cooperation at the European Union level for joint clinical assessments in these areas. It will permit European Union member states to use common HTA tools, methodologies, and procedures across the European Union, working together in four main areas, including joint clinical assessment of the innovative health technologies with the highest potential impact for patients, joint scientific consultations whereby developers can seek advice from HTA authorities, identification of emerging health technologies to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual European Union Member States will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technology, and making decisions on pricing and reimbursement.
We expect that these healthcare reforms, as well as other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria and new payment methodologies that govern any approved product and/or the level of reimbursement physicians receive for administering any approved product we might bring to market. Reductions in reimbursement levels may negatively impact the prices we receive or the frequency with which our products are prescribed or administered. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. Accordingly, such reforms, if enacted, could have an adverse effect on anticipated revenue from product candidates for which we may obtain marketing approval and may affect our overall financial condition and ability to develop or commercialize product candidates.
The insurance coverage and reimbursement status of newly approved products is uncertain. Product candidates, if approved, may become subject to unfavorable pricing regulations, third-party coverage and reimbursement practices, or healthcare reform initiatives, which would harm our business. Failure to obtain or maintain coverage and adequate reimbursement for any product candidates for which we obtain approval could limit our ability to market those products and decrease our ability to generate revenue.
The regulations that govern marketing approvals, pricing, coverage, and reimbursement for new drugs and other medical products vary widely from country to country. In the United States, healthcare reform legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, pricing remains subject to continuing governmental control even
91
after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenue we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more products or product candidates, even if any product candidates we may develop obtain marketing approval.
Our ability to successfully commercialize our products and product candidates also will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers, and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. The availability of coverage and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford treatments such as gene therapy products. Sales of these or other product candidates that we may identify will depend substantially, both domestically and abroad, on the extent to which the costs of our products and product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors. If coverage and adequate reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize our products or product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment. A primary trend in the United States healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. In general, the prices of medicines under such systems are substantially lower than in the United States. Other countries allow companies to fix their own prices for medicines, but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our products and product candidates. Accordingly, in markets outside the United States, the reimbursement for products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenues and profits.
There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the principal decisions about reimbursement for new medicines are typically made by CMS. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree. No uniform policy of coverage and reimbursement for products exists among third-party payors and coverage and reimbursement levels for products can differ significantly from payer to payer. As a result, the coverage determination process is often a time consuming and costly process that may require us to provide scientific and clinical support for the use of our products to each payer separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. It is difficult to predict what CMS will decide with respect to reimbursement for fundamentally novel products such as ours, as there is no body of established practices and precedents for these new products.
Reimbursement agencies in Europe may be more conservative than CMS. For example, a number of cancer products have been approved for reimbursement in the United States and have not been approved for reimbursement in certain European countries. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale, and distribution. Interim reimbursement levels for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the product and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost products and may be incorporated into existing payments for other services. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved products we may develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize product candidates, and our overall financial condition.
Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices than in the United States. Our inability to promptly obtain coverage and profitable reimbursement rates from third-party payors for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.
Increasingly, third-party payors are requiring that pharmaceutical companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of reimbursement. Reimbursement may impact the demand for, or the price of, any product or product candidate for which we obtain marketing approval. In order to obtain reimbursement, physicians may need to show that patients have superior treatment outcomes with our products compared to
92
standard-of-care products, including lower-priced generic versions of standard-of-care products. We expect to experience pricing pressures in connection with the sale of any of our product candidates, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription products and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.
The prices of prescription pharmaceuticals in the United States and foreign jurisdictions are subject to considerable legislative and executive actions and could impact the prices we obtain for our products, if and when approved.
The prices of prescription pharmaceuticals have also been the subject of considerable discussion in the United States. There have been congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency to pharmaceutical pricing, review the relationship between pricing and manufacturer patient programs, and reduce the costs of pharmaceuticals under Medicare and Medicaid.
In addition, in October 2020, HHS and the FDA published a final rule allowing states and other entities to develop a Section 804 Importation Program (“SIP”) to import certain prescription products from Canada into the United States. That regulation was challenged in a lawsuit by the Pharmaceutical Research and Manufacturers of America (“PhRMA”) but the case was dismissed by a federal district court in February 2023 after the court found that PhRMA did not have standing to sue HHS. A number of states have submitted SIP proposals to the FDA with the goal of obtaining authority to import drugs from Canada, subject to conditions. On January 5, 2024, the FDA approved Florida’s plan for Canadian importation. That state now has authority to import certain products from Canada for a period of two years once certain conditions are met. Florida will first need to submit a pre-import request for each product selected for importation, which must be approved by the FDA. The state will also need to relabel the products and perform quality testing of the products to meet FDA standards. On May 21, 2025, the FDA announced that it would offer individual states the opportunity to submit a draft proposal for pre-review and meet with the agency to obtain initial feedback from FDA prior to formally submitting their SIP proposal. The intent of these meetings is to assist states in developing their proposals by further clarifying requirements, enhancing the quality of proposals submitted to the agency and ultimately shortening the review timeline.
Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The final rule would also eliminate the current safe harbor for Medicare rebates and create new safe harbors for beneficiary point-of-sale discounts and pharmacy benefit manager service fees. It was originally set to go into effect on January 1, 2022, but with passage of the IRA, has been delayed by Congress to January 1, 2032.
On August 16, 2022, the IRA was enacted. The new legislation has implications for Medicare Part D, which is a program available to individuals who are entitled to Medicare Part A or enrolled in Medicare Part B to give them the option of paying a monthly premium for outpatient prescription product coverage. The IRA also, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. Further, the IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and through a newly established manufacturer discount program. It is unclear how any additional challenges or future healthcare reform measures will impact the ACA.
Among other things, the IRA requires manufacturers of certain products to engage in price negotiations with Medicare (beginning in 2026), with prices that can be negotiated subject to a cap and it replaces the Part D coverage gap discount program with a new discounting program (beginning in 2025). In addition, the IRA established inflation rebate programs under Medicare Part B and Part D. These programs require manufacturers to pay rebates to Medicare if they raise their prices for certain Part B and Part D drugs faster than the rate of inflation. On December 9, 2024, with issuance of its 2025 Physician Fee Schedule final regulation, CMS finalized its rules governing the IRA inflation rebate programs. The IRA permits the Secretary of HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years.
Specifically, with respect to price negotiations, Congress authorized Medicare to negotiate lower prices for certain costly single-source drug and biologic products that do not have competing generics or biosimilars and are reimbursed under Medicare Part B and Part D. CMS may negotiate prices for ten high-cost products paid for by Medicare Part D starting in 2026, followed by 15 Part D drugs in 2027, 15 Part B or Part D drugs in 2028, and 20 Part B or Part D drugs in 2029 and beyond. This provision applies to drug products that have been approved for at least nine years and biologics that have been licensed for 13 years. With passage of the One Big Beautiful Bill Act (“OBBBA”) in July 2025, Congress expanded the exemption from this provision to drugs and biologics with multiple orphan drug designations. Since CMS may establish a maximum price for these products in price negotiations, we would be fully at risk of government action if our products are the subject of Medicare price negotiations. Moreover, given the risk that could be the case, these provisions of the IRA may also further heighten the risk that we would not be able to achieve the expected return on our drug products or full value of our patents protecting our products if prices are set after such products have been on the market for nine years.
93
The first cycle of negotiations for the Medicare Drug Price Negotiation Program commenced in the summer of 2023 with the negotiated prices for ten selected drug products becoming effective on January 1, 2026. The second cycle of negotiations with participating drug companies occurred during 2025, and the negotiated prices for this second set of 15 drugs will be effective on January 1, 2027. On January 27, 2026, CMS published the list of 15 drugs selected for the third cycle of negotiations. These negotiated prices will become effective on January 1, 2028.
Further, the legislation subjects drug manufacturers to civil monetary penalties and a potential excise tax for failing to comply with the legislation by offering a price that is not equal to or less than the negotiated “maximum fair price” under the law or for taking price increases that exceed inflation. The legislation also requires manufacturers to pay rebates for drugs in Medicare Part D whose price increases exceed inflation. The new law also caps Medicare out-of-pocket drug costs at an estimated US$4,000 a year in 2024 and, thereafter beginning in 2025, at US$2,000 a year.
On June 6, 2023, Merck & Co. filed a lawsuit against HHS and CMS asserting that, among other things, the IRA’s Drug Price Negotiation Program for Medicare constitutes an uncompensated taking in violation of the Fifth Amendment of the Constitution. Subsequently, a number of other parties also filed lawsuits in various courts with similar constitutional claims. Every court that has thus far considered substantive challenges to the Medicare drug price negotiation program has ruled against the pharmaceutical industry, dismissing both constitutional and statutory arguments. For example, on May 8, 2025, the U.S. Court of Appeals for the Third Circuit rejected AstraZeneca L.P.’s challenge to the Medicare price negotiation program, finding that the program did not violate the company’s due process rights under the constitution since there is no protected property interest in selling goods to Medicare beneficiaries at a price higher than what the government is willing to pay in reimbursement. We expect that litigation involving these and other provisions of the IRA will continue, with unpredictable and uncertain results.
Since adoption of the IRA, the Trump Administration has taken a number of actions to reduce the costs of pharmaceutical products. On April 15, 2025, President Trump issued an Executive Order which directs HHS to take steps to reduce the prices of pharmaceutical products. Further, on May 12, 2025, President Trump issued an additional Executive Order calling on pharmaceutical manufacturers to voluntarily reduce the prices of medicines in the United States. The Executive Order directs the Secretary of HHS to communicate MFN price targets to pharmaceutical manufacturers to bring prices in line with comparably developed nations. The Executive Order further provides that if such actions do not lower the costs of pharmaceuticals, the Secretary of HHS would pursue other actions, including proposing a rulemaking that imposes MFN pricing in the United States.
Thereafter, on July 31, 2025, President Trump issued letters to 17 pharmaceutical companies reiterating the requirements of the May 12, 2025, Executive Order and demanding that such companies extend MFN pricing to Medicaid patients. Virtually all of these pharmaceutical companies entered into agreements with the Trump Administration to provide for lower prices on certain pharmaceuticals. On February 5, 2026, President Trump launched TrumpRx.gov, a website that directs individuals to pharmaceutical manufacturer websites that are offering price discounts based on the administration’s pricing agreements with pharmaceutical manufacturers.
Separately, on December 23, 2025, CMS, through its Center for Medicare and Medicaid Innovation, proposed two five-year pilot programs to implement a “reference pricing” regime for drugs paid for under Medicare for 25% of covered beneficiaries. The programs are referred to as the Global Benchmark for Efficient Drug Pricing (GLOBE) Model for Medicare Part B drugs, and the Guarding U.S. Medicare Against Rising Drug Costs for Medicare Part D drugs. Under the proposed pilot programs, a manufacturer would owe rebates to Medicare if prices for their drugs exceeded the prices paid by other economically comparable reference countries, defined in the proposed regulations as OECD countries with a GDP of $400 billion and a per capita GDP that is at least 60% of the U.S. per capita GDP (an initial list of 19 reference countries is included in the proposed rule). These pilot programs are proposed to go into effect beginning October 1, 2026.
At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. This is increasingly true with respect to products approved pursuant to the accelerated approval pathway. State Medicaid programs and other payers are developing strategies and implementing significant coverage barriers, or refusing to cover these products outright, arguing that accelerated approval drugs have insufficient or limited evidence despite meeting the FDA’s standards for accelerated approval. In addition, regional healthcare organizations and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription product and other healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. This may be especially true with respect to products approved pursuant to the accelerated approval pathway. State Medicaid programs and other payers are
94
developing strategies and implementing significant coverage barriers, or refusing to cover these products outright, arguing that accelerated approval drugs have insufficient or limited evidence despite meeting the FDA’s standards for accelerated approval.
Finally, outside of the United States, in some countries, including those of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control and access. In these countries, official list price country pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies.
These measures, as well as others adopted in the future, may result in additional downward pressure on the price that we receive for any approved product it or its collaborators might bring to market. Accordingly, such reforms, if enacted, could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain marketing approval and may affect our overall financial condition and ability to develop or commercialize product candidates.
We are subject to stringent privacy laws, information security laws, regulations, policies and contractual obligations related to data privacy and security and changes in such laws, regulations, policies, contractual obligations and failure to comply with such requirements could subject us to significant fines and penalties, which may have a material adverse effect on our business, financial condition or results of operations.
We are subject to data privacy and protection laws and regulations that apply to the collection, transmission, storage and use of personally-identifying information, which among other things, impose certain requirements relating to the privacy, security and transmission of personal information, including comprehensive regulatory systems in the United States, European Union, United Kingdom and other countries in which we may conduct business. The legislative and regulatory landscape for privacy and data protection continues to evolve in jurisdictions worldwide, and there has been an increasing focus on privacy and data protection issues with the potential to affect our business. Failure to comply with any of these laws and regulations could result in enforcement action against us, including fines, imprisonment of company officials and public censure, claims for damages by affected individuals, damage to its reputation and loss of goodwill, any of which could have a material adverse effect on our business, financial condition, results of operations or prospects.
There are numerous United States federal and state laws and regulations related to the privacy and security of personal information. In particular, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act establish privacy and security standards that limit the use and disclosure of individually identifiable health information, or protected health information, and require the implementation of administrative, physical and technological safeguards to protect the privacy of protected health information and ensure the confidentiality, integrity and availability of electronic protected health information. Determining whether protected health information has been handled in compliance with applicable privacy standards and our contractual obligations can be complex and may be subject to changing interpretation. These obligations may be applicable to some or all of our business activities now or in the future.
If we are unable to properly protect the privacy and security of protected health information, we could be found to have breached its contracts. Further, if we fail to comply with applicable privacy laws, including applicable HIPAA privacy and security standards, we could face civil and criminal penalties. HHS enforcement activity can result in financial liability and reputational harm, and responses to such enforcement activity can consume significant internal resources. In addition, state attorneys general are authorized to bring civil actions seeking either injunctions or damages in response to violations that threaten the privacy of state residents. We cannot be sure how these regulations will be interpreted, enforced or applied to its operations in the future. In addition to the risks associated with enforcement activities and potential contractual liabilities, our ongoing efforts to comply with evolving laws and regulations at the federal and state level may be costly and require ongoing modifications to our policies, procedures and systems.
In 2018, California passed into law the California Consumer Privacy Act (“CCPA”), which took effect on January 1, 2020 and imposed many requirements on businesses that process the personal information of California residents. Many of the CCPA’s requirements are similar to those found in the General Data Protection Regulation 2016/679 (“EU GDPR”) (regarding individuals in the EEA) and, the UK General Data Protection Regulation (“UK GDPR”) (regarding individuals in the United Kingdom (“UK”)), as well as applicable data protection laws in effect in the Member States of the EEA and in the UK (including the UK Data Protection Act 2018), including requiring businesses to provide notice to data subjects regarding the information collected about them and how such information is used and shared, and providing data subjects the right to request access to such personal information and, in certain cases, request the erasure of such personal information. The EU and UK data protection regimes are independent of each other but remain largely aligned. In this Current Report on Form 8-K, “GDPR” refers to both the EU GDPR and the UK GDPR, unless specified otherwise, and applies to any company established in the EEA/UK and to companies established outside the EEA/UK that process personal data in connection with the offering of goods or services to data subjects in the EEA/UK or the monitoring of the
95
behavior of data subjects in the EEA/UK. The CCPA also affords California residents the right to opt-out of the “sale” of their personal information. The CCPA contains significant penalties for companies that violate its requirements. In November 2020, California voters passed a ballot initiative for the California Privacy Rights Act (the “CPRA”), which went into effect on January 1, 2023 and significantly expanded the CCPA to incorporate additional GDPR-like provisions including requiring that the use, retention, and sharing of personal information of California residents be reasonably necessary and proportionate to the purposes of collection or processing, granting additional protections for sensitive personal information, and requiring greater disclosures related to notice to residents regarding retention of information. The CPRA also created a new enforcement agency - the California Privacy Protection Agency - whose sole responsibility is to enforce the CPRA and other California privacy laws, which will further increase compliance risk. The provisions in the CPRA may apply to some of our business activities.
In addition to California, a number of other states have passed comprehensive privacy laws similar to the CCPA and CPRA. These laws are either in effect or will go into effect sometime before the end of 2026. Like the CCPA and CPRA, these laws create obligations related to the processing of personal information, as well as special obligations for the processing of “sensitive” data, which includes health data in some cases. Some of the provisions of these laws may apply to our business activities. There are also states that are strongly considering or have already passed comprehensive privacy laws that will go into effect in 2025 and beyond. Congress has also been debating passing a federal privacy law. These laws may impact our business activities, including our identification of research subjects, relationships with business partners and ultimately the marketing and distribution of our products.
Similar to the laws in the United States, there are significant privacy and data security laws that apply in Europe and other countries. The collection, use, disclosure, transfer, or other processing of personal data, including personal health data, regarding individuals who are located in the European Economic Area (“EEA”), and the processing of personal data that takes place in the EEA, is regulated by the GDPR, which went into effect in May 2018 and which imposes obligations on companies that operate in our industry with respect to the processing of personal data and the cross-border transfer of such data. The GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and policies. If we or our partners’ or service providers’ privacy or data security measures fail to comply with the GDPR requirements, we may be subject to litigation, regulatory investigations, enforcement notices requiring it to change the way we use personal data and/or fines of up to 20 million Euros or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher, as well as compensation claims by affected individuals, negative publicity, reputational harm and a potential loss of business and goodwill.
The GDPR places restrictions on the cross-border transfer of personal data from the European Union to countries that have not been found by the European Commission to offer adequate data protection legislation, such as the United States. There are ongoing concerns about the ability of companies to transfer personal data from the European Union to other countries. In July 2020, the Court of Justice of the European Union (the “CJEU”) invalidated the EU-U.S. Privacy Shield, one of the mechanisms used to legitimize the transfer of personal data from the EEA to the United States. The CJEU decision also drew into question the long-term viability of an alternative means of data transfer, the standard contractual clauses, for transfers of personal data from the EEA to the United States. This CJEU decision may lead to increased scrutiny on data transfers from the EEA to the United States generally and increase our costs of compliance with data privacy legislation as well as its costs of negotiating appropriate privacy and security agreements with its vendors and business partners.
Following the July 2020 Court of Justice of the European Union judgement invalidating the so-called EU-U.S. Privacy Shield, the European Commission adopted an adequacy decision for the EU-U.S. Data Privacy Framework in July 2023. This adequacy decision permits U.S. companies who self-certify under the EU-U.S. Data Privacy Framework to rely on it as a valid data transfer mechanism for data transfers from the European Union to the United States. However, some privacy advocacy groups have already suggested that they will be challenging the EU-U.S. Data Privacy Framework, and there is currently one pending litigation against the EU-U.S. Data Privacy Framework before the Court of Justice of the European Union (CJEU), C-703/25 P – Latombe v Commission. If these challenges are successful, they may not only impact the EU-U.S. Data Privacy Framework, but also further limit the viability of the so-called standard contractual clauses and other data transfer mechanisms.
Additionally, in October 2022, President Biden signed an executive order to implement the EU-U.S. Data Privacy Framework, which serves as a replacement to the EU-U.S. Privacy Shield. The European Union initiated the process to adopt an adequacy decision for the EU-U.S. Data Privacy Framework in December 2022, and the European Commission adopted the adequacy decision on July 10, 2023. The adequacy decision permits United States companies who self-certify to the EU-U.S. Data Privacy Framework to rely on it as a valid data transfer mechanism for data transfers from the European Union to the United States. However, some privacy advocacy groups have already suggested that they will be challenging the EU-U.S. Data Privacy Framework. If these challenges are successful, they may not only impact the EU-U.S. Data Privacy Framework, but also further limit the viability of the standard contractual clauses and other data transfer mechanisms. The uncertainty around this issue has the potential to impact our business. Following the withdrawal of the United Kingdom from the European Union, the United Kingdom Data Protection Act 2018 applies to the processing of personal data that takes place in the United Kingdom and includes parallel obligations to those set forth by GDPR. In relation to data transfers, both the United Kingdom and the European Union have determined, through separate “adequacy” decisions, that data transfers between the two jurisdictions are in compliance with the U.K. Data Protection Act and the GDPR, respectively. The United Kingdom and the United States have also agreed to a U.S.-U.K. “Data Bridge,” which functions similarly to the EU-U.S. Data
96
Privacy Framework and provides an additional legal mechanism for companies to transfer data from the United Kingdom to the United States. In addition to the United Kingdom, Switzerland is also in the process of approving an adequacy decision in relation to the Swiss-U.S. Data Privacy Framework (which would function similarly to the EU-U.S. Data Privacy Framework and the U.S.-U.K. Data Bridge in relation to data transfers from Switzerland to the United States). Any changes or updates to these developments have the potential to impact our business.
Beyond GDPR, there are privacy and data security laws in a growing number of countries around the world. While many loosely follow GDPR as a model, other laws contain different or conflicting provisions. These laws will impact our ability to conduct its business activities, including both our clinical trials and the sale and distribution of commercial products, through increased compliance costs, costs associated with contracting and potential enforcement actions.
While we continue to address the implications of the recent changes to data privacy regulations, data privacy remains an evolving landscape at both the domestic and international level, with new regulations coming into effect and continued legal challenges, and our efforts to comply with the evolving data protection rules may be unsuccessful. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. We must devote significant resources to understanding and complying with this changing landscape. Failure to comply with laws regarding data protection would expose us to risk of enforcement actions taken by data protection authorities in the EEA and elsewhere and carries with it the potential for significant penalties if we are found to be non-compliant. Similarly, failure to comply with federal and state laws in the United States regarding privacy and security of personal information could expose us to penalties under such laws. Any such failure to comply with data protection and privacy laws could result in government-imposed fines or orders requiring that we change our practices, claims for damages or other liabilities, regulatory investigations and enforcement action, litigation and significant costs for remediation, any of which could adversely affect our business. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our business, financial condition, results of operations or prospects.
Changes in and uncertainty surrounding U.S. and internal trade policy could have a material adverse impact on our business, financial condition and results of operations.
In the spring of 2025, the Trump Administration initiated a series of tariff-related actions against U.S. trading partners. On April 2, 2025, President Trump issued an Executive Order announcing a “baseline” reciprocal tariff of 10% on all U.S. trading partners effective April 5, 2025, and higher individualized reciprocal tariffs on 57 countries (with certain product exemptions for pharmaceutical-related products, among others). Previously, the administration had imposed a 25% tariff on Canada and Mexico for goods not covered by the United States-Mexico-Canada Agreement (“USMCA”), and tariffs equaling 20% on imports from China. In response, several countries threatened retaliatory measures, including Canada and China, which then imposed retaliatory tariffs. Prior to when the country-specific reciprocal tariffs were scheduled to take effect, the administration delayed the effective date of such tariffs for all countries except China to August 1, 2025. Later, the United States and China reached a framework agreement that ultimately resulted in the suspension of the higher reciprocal tariffs on China until November 10, 2025. Shortly before that expiration date, the United States and China reached a one-year agreement with an expiration of November 10, 2026, that includes the continued suspension of the heightened reciprocal tariffs on China and delayed enforcement of new U.S. export rules targeting affiliates of blacklisted firms.
Since the April 2025 reciprocal tariffs announcement, several countries have reached framework agreements to reduce tariff rates and other measures with the United States, including the United Kingdom, Vietnam and Indonesia, Japan, the Philippines, the EU, South Korea, Thailand, Malaysia, Cambodia, China, El Salvador, Argentina, Ecuador, Guatemala, Switzerland and Liechtenstein, and Taiwan. On July 31, 2025, the United States administration issued an executive order detailing new reciprocal tariff rates for individual countries that took effect on August 7, 2025. The deals with the European Union, Japan, South Korea, Switzerland (and Liechtenstein), the United Kingdom and others cap pharmaceutical tariffs at 15%. In addition, an agreement with Malaysia provides a zero percent tariff exemption for pharmaceutical products that are not patented in the U.S. and are used in pharmaceutical applications and an agreement with Switzerland and Lichenstein caps tariffs on pharmaceuticals imported from those two countries at 15%. Finally, an agreement with Taiwan concluded on January 15, 2026 eliminates tariffs on generic pharmaceuticals and their active ingredients imported from Taiwan.
The reciprocal tariffs were imposed pursuant to the International Emergency Economic Powers Act (the “IEEPA”). These tariffs were found to be unconstitutional by multiple federal courts in the spring and summer of 2025. On February 20, 2026, the U.S. Supreme Court held that IEEPA does not authorize the President to impose tariffs, invalidating the reciprocal tariffs. Shortly thereafter, President Trump issued a new Executive Order revoking the IEEPA tariffs and Customs and Border Protection ceased collecting the tariffs as of 12:01 am on February 24, 2026. At the same time, however, the Trump Administration imposed a new 10% global tariff under Section 122 of the Trade Act of 1974, or the Trade Act, effective February 24, 2026. Pursuant to the statute, absent an extension by Congress, these tariffs will expire in 150 days on July 24, 2026. For those countries that have concluded trade deals with the United States, the tariff rates agreed to, including with regard to pharmaceuticals and pharmaceutical ingredients, have now reverted to 10% until July 24, 2026.
97
Like the IEEPA tariffs, pharmaceuticals and pharmaceutical ingredients are exempt from the tariffs under Section 122 of the Trade Act along with a list of other products. The Trump Administration has announced that it also plans to initiate new investigations on “most major trading partners” under Section 301 of the Trade Act, which will likely lead to additional tariffs. Neither the U.S. Supreme Court’s decision nor the Executive Order revoking the IEEPA tariffs addressed refunds, leaving the issue to renewed proceedings before the U.S. Court of International Trade, where importers may need to pursue administrative remedies and/or litigation amid continued uncertainty.
Sustained uncertainty about, or the further escalation of, trade and political tensions between the United States and China could result in a disadvantageous research and manufacturing environment in China, particularly for U.S. based companies, including retaliatory restrictions that hinder or potentially inhibit our ability to rely on CDMOs and other service providers that operate in China.
Separately, in April 2025, the Department of Commerce initiated an investigation under Section 232 of the Trade Expansion Act of 1962 into the impact on U.S. national security of the imports of pharmaceuticals and pharmaceutical ingredients, including finished drug products, medical countermeasures, critical inputs such as active pharmaceutical ingredients, and key starting materials, and derivative products of those items. On September 25, 2025, via a post on Truth Social, President Trump announced that, beginning October 1, 2025, all branded or patented drugs imported in the United States would face a 100% tariff. At the same time, President Trump indicated that these tariffs could be avoided by building pharmaceutical manufacturing facilities in the United States. Thereafter, President Trump delayed the October 1, 2025 effective date of the tariffs on branded or patented pharmaceutical products announcing that the Trump Administration had now “begun preparing” tariffs on manufacturers that do not build in the United States or enter into a most-favored-nation drug pricing agreement with the Trump Administration.
On April 2, 2026, President Trump issued a Proclamation invoking Section 232 of the Trade Expansion Act of 1962 to impose tariffs on imports of patented pharmaceuticals, biologics, and associated ingredients into the United States. The action affects pharmaceutical manufacturers, importers, and supply chain participants. Specifically, beginning July 31, 2026, a 100% tariff will apply to pharmaceutical articles that are subject to a valid, unexpired U.S. patent and are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations or are listed in the FDA’s Lists of Licensed Biological Products . The 100% tariff also applies to active pharmaceutical ingredients and key starting materials for such articles. Certain categories of products are exempt from these tariffs, including generic pharmaceuticals and biosimilars; U.S.-origin pharmaceutical products, active pharmaceutical ingredients and key starting materials; products classified in certain 10-digit tariff codes, listed in Annex IV of the Proclamation; drugs and associated ingredients for all approved indications that are designated as orphan pursuant to the Orphan Drug Act; drugs for certain specific uses, including nuclear medicines; plasma-derived therapies; fertility treatments; cell and gene therapies; antibody drug conjugates; medical countermeasures related to chemical, biological, radiological, and nuclear threats; animal health; and other specialty pharmaceutical products to be later identified by the Secretary of Commerce; and goods that qualify as “prototypes to be used exclusively for development, testing, product evaluation, or quality control purposes,” may be excluded from the additional tariffs.
As a result of changes in tariffs that have been announced and/or implemented, and the underlying uncertainty currently surrounding international trade, we could experience a negative impact to our costs of materials and production processes, and supply chain disruptions and delays as a result of any new tariff policies or trade restrictions. If we are unable to obtain necessary raw materials or product components in sufficient quantity and in a timely manner due to disruptions in the global supply chain caused by macroeconomic events and conditions, the development, testing and clinical trials of our product candidates may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business. We cannot yet predict the effect of the recently imposed U.S. tariffs on imports, or the extent to which other countries will impose quotas, duties, tariffs, taxes or other similar restrictions upon imports or exports in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business.
Risks Related to Employee Matters and Managing Growth
Our future success depends on our ability to retain key executives and experienced scientists and to attract, retain and motivate qualified personnel.
We are highly dependent on the research and development, clinical, financial, operational and other business expertise of our executive officers, as well as the other principal members of our management, scientific and clinical teams. Although we entered into employment agreements with certain of our executive officers, each of them may terminate their employment with us at any time. We do not maintain “key person” insurance for any of its executives or other employees. Recruiting and retaining qualified scientific, clinical, manufacturing, accounting, legal and sales and marketing personnel is also critical to our success.
In addition, the loss of the services of our executive officers or other key employees, including temporary loss due to illness, could impede the achievement of our development and commercialization objectives and seriously harm our ability to successfully
98
implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain marketing approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous biopharmaceutical companies for similar personnel.
We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. Failure to succeed in clinical trials may make it even more challenging to recruit and retain qualified scientific personnel. Our success as a public company also depends on implementing and maintaining internal controls and the accuracy and timeliness of its financial reporting. If we are unable to continue to attract and retain high quality personnel, our ability to pursue its growth strategy will be limited.
We expect to expand our development and regulatory capabilities and potentially implement sales, marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.
We expect to experience significant growth in the number of our employees and the scope of our operations, particularly as we function as a public company and in the areas of product development, clinical, regulatory affairs, manufacturing and quality control and, if any of our product candidates receives marketing approval, sales, marketing, and distribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Future growth will impose significant added responsibilities on members of our management, including:
Our future financial performance and our ability to advance development of and, if approved, commercialize TH103 and any other product candidate we are developing or may develop in the future will depend, in part, on our ability to effectively manage any future growth. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. If we do not effectively manage the expansion of our operations, we could experience weaknesses in our infrastructure, operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. The expansion of our operations could also lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.
Many of the biopharmaceutical companies that we compete against for qualified personnel and consultants have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel and consultants, the rate and success at which we can develop product candidates and operate our business will be limited.
Our internal computer systems, or those of our collaborators, vendors, suppliers, contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our product development programs.
Our internal computer systems and those of any of our collaborators, vendors, suppliers, contractors or consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such systems are also vulnerable to service interruptions or to security breaches from inadvertent or intentional actions by our employees, third-party vendors and/or business partners, or from cyber-attacks by malicious third parties. Cyber-attacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect. Cyber-attacks could include the deployment of harmful malware, ransomware, denial-of-service attacks, unauthorized access to or deletion of files, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information. Cyber-attacks also could include phishing attempts or email fraud to cause payments or information to be transmitted to an unintended recipient.
99
If we experience any material system failure, accident, cyber-attack or security that causes interruptions in our operations, it could result in a material disruption of our development programs and our business operations, whether due to a loss of its trade secrets or other proprietary information or other similar disruptions. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability, our competitive position could be harmed, and the further development and commercialization of our product candidates could be delayed.
Our employees, independent contractors, including principal investigators, consultants and vendors and any third parties we may engage in connection with research, development, regulatory, manufacturing, quality assurance and other pharmaceutical functions and commercialization may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, which could cause significant liability for us and harm our reputation.
We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, including principal investigators, consultants and vendors and any other third parties we engage. Misconduct by these parties could include intentional, reckless or negligent conduct or unauthorized activities that include failures to comply with FDA regulations or similar regulations of comparable foreign regulatory authorities, provide complete and accurate information to the FDA or comparable foreign regulatory authorities, comply with manufacturing standards, comply with federal and state data privacy, security, fraud and other healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable foreign regulatory authorities, report complete financial information or data accurately or disclose unauthorized activities to us. Misconduct by employees and other third parties could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. This could include violations of HIPAA, other United States federal and state law, and requirements of non-United States jurisdictions, including the European Union Data Protection Directive. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws, standards, regulations, guidance or codes of conduct. Additionally, we are subject to the risk that a person could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, Medicaid, other United States federal healthcare programs or healthcare programs in other jurisdictions, integrity oversight and reporting obligations to resolve allegations of non-compliance, individual imprisonment, other sanctions, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations.
Risks Related to the Ownership of Our Common Stock
The market price of our common stock has been and is expected to continue to be volatile.
The trading price of our common stock has been and is expected to continue to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. In addition to the factors discussed in this “Risk Factors” section, these factors include:
100
Moreover, the stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations may also adversely affect the trading price of our common stock. In addition, a recession, depression or other sustained adverse market event could materially and adversely affect our business and the value of our common stock. In the past, following periods of volatility in the market price of a company’s securities, stockholders have often instituted class action securities litigation against such companies. Furthermore, market volatility may lead to increased shareholder activism if we experience a market valuation that activists believe is not reflective of its intrinsic value. Activist campaigns that contest or conflict with our strategic direction or seek changes in the composition of our board of directors could have an adverse effect on our operating results and financial condition.
We incur additional costs and increased demands upon management as a result of complying with the laws and regulations affecting public companies.
As a public company, we incur significant legal, accounting and other expenses as a public company that we did not incur as a private company. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which requires, among other things, that we file with the SEC annual, quarterly, and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of The Nasdaq Global Market and other applicable securities rules and regulations impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. Stockholder activism, the current political environment, and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate.
Our executive officers and other personnel need to devote substantial time to gaining expertise related to public company reporting requirements and compliance with applicable laws and regulations to ensure that we comply with all of these requirements. Any changes we make to comply with these obligations may not be sufficient to allow us to satisfy our obligations as a public company on a timely basis, or at all. These reporting requirements, rules and regulations, coupled with the increase in potential litigation exposure associated with being a public company, could also make it more difficult for us to attract and retain qualified persons to serve on the board of directors or on board committees or to serve as executive officers, or to obtain certain types of insurance, including directors’ and officers’ insurance, on acceptable terms.
We are a “smaller reporting company,” and the reduced disclosure requirements applicable to smaller reporting companies may make our common stock less attractive to investors.
We are a “smaller reporting company” as defined in Rule 12b-2 under the Exchange Act. We would cease to be a smaller reporting company if we have a public float in excess of $250 million or have annual revenues in excess of $100 million and a public float in excess of $700 million, determined on an annual basis.
101
As a smaller reporting company, we are permitted to and intend to rely on exemptions from disclosure requirements that are applicable to other public companies that are not smaller reporting companies, including:
102
We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.
Anti-takeover provisions under our charter documents and Delaware law could delay or prevent a change of control, which could limit the market price of our common stock and may prevent or frustrate attempts by our stockholders to replace or remove our current management.
Our restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change of control of us or changes in our board of directors that our stockholders might consider favorable. Some of these provisions include:
In addition, because we are incorporated in Delaware, we will be governed by the provisions of Section 203 of the Delaware General Corporate Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These antitakeover provisions and other provisions in our restated certificate of incorporation and amended and restated bylaws could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors and could also delay or impede a merger, tender offer, or proxy contest involving us. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing or cause us to take other corporate actions they desire. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.
Our amended and restated bylaws designates certain courts as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.
Our amended and restated bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any state law claim for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers, and employees to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our restated certificate of incorporation or our amended and restated bylaws or (iv) any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein (the “Delaware Forum Provision”). The Delaware Forum Provision will not apply to any causes of action arising under the Securities Act or the Exchange Act. Our amended and restated bylaws further provide that, unless we consent in writing to the selection of an alternative forum, the United States District Court for the District of Massachusetts shall be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”). In addition, our amended and restated bylaws will provide that any person or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed to have notice of and consented to the foregoing provisions; provided, however, that stockholders cannot and will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.
103
The Delaware Forum Provision and the Federal Forum Provision that are in our amended and restated bylaws may impose additional litigation costs on stockholders in pursuing any such claims, particularly if the stockholders do not reside in or near the State of Delaware or the Commonwealth of Massachusetts. Additionally, the forum selection clauses in our amended and restated bylaws may limit our stockholders’ ability to bring a claim in a forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage such lawsuits against us and our directors, officers and employees even though an action, if successful, might benefit our stockholders. In addition, while the Delaware Supreme Court and other state courts have upheld the validity of forum selection provisions purporting to require claims under the Securities Act be brought in federal court, there is uncertainty as to whether other courts will enforce our Federal Forum Provision. If the Federal Forum Provision is found to be unenforceable, we may incur additional costs associated with resolving such matters. The Federal Forum Provision may also impose additional litigation costs on stockholders who assert that the provision is not enforceable or invalid. The Court of Chancery of the State of Delaware and the United States District Court for the District of Massachusetts may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us and our stockholders.
We do not anticipate paying any cash dividends in the foreseeable future.
We currently anticipate that we will retain our future earnings, if any, to fund the growth of our business as opposed to paying dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain, if any, for the foreseeable future.
We do not know whether an active, liquid and orderly trading market will develop for our common stock or what the market price of our common stock will be and, as a result, it may be difficult for our stockholders to sell shares of our common stock.
AlloVir’s IPO closed on August 3, 2020. Prior to AlloVir’s IPO, there was no public market for shares of its common stock. Prior to the Merger, there had been no public market for shares of Legacy Kalaris capital stock. Although AlloVir completed its IPO and the Merger has closed, and shares of our common stock are listed and trading on The Nasdaq Global Market, an active trading market for our shares may never develop or be sustained. Our stockholders may not be able to sell shares quickly or at the market price if trading in shares of our common stock is not active. Further, an inactive market may also impair our ability to raise capital by selling shares of our common stock and may impair our ability to enter into strategic partnerships or acquire companies or products by using our shares of common stock as consideration.
Transfers of our securities utilizing Rule 144 of the Securities Act may be limited.
A significant portion of our securities are restricted from immediate resale. Holders should be aware that transfers of our securities pursuant to Rule 144 may be limited as Rule 144 is not available, subject to certain exceptions, for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. Our possible disposal of certain of AlloVir’s historical assets and operations in connection with the Merger made AlloVir subject to the SEC requirements applicable to reporting shell company business combinations. Following the consummation of the Merger, we are no longer a shell company. As a result, we anticipate that holders will not be able to sell their restricted securities of ours pursuant to Rule 144 without registration until one year after March 18, 2025, the date that we filed the Current Report on Form 8-K following the closing of the Merger that includes the required Form 10 information which reflects that we are no longer a shell company.
Our possible disposal of certain of AlloVir’s historical assets and operations, the discontinuation of AlloVir’s product development programs and the Merger made AlloVir subject to the SEC requirements applicable to reporting shell company business combinations. As a result, we are subject to more stringent reporting requirements, offering limitations and resale restrictions.
According to SEC guidance, the requirements applicable to reporting shell company business combinations apply to any company that sells or otherwise disposes of its historical assets or operations in connection with or as part of a plan to combine with a non-shell private company in order to convert the private company into a public one. AlloVir discontinued the development of its product candidates and we may seek to dispose of certain of AlloVir’s historical assets and operations. As such, the Merger was subject to the SEC requirements applicable to reporting shell company business combinations, which are as follows:
104
The foregoing SEC requirements will increase our time and cost of raising capital, offering stock under equity plans, and compliance with securities laws. Further, such requirements will add burdensome restrictions on the resale of our shares by affiliates of Legacy Kalaris and any holders of “restricted” or “control” securities.
Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to the 2020 Plan or the 2019 Plan, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.
We expect that significant additional capital may be needed in the future to continue our planned operations, including conducting clinical trials, expanded research and development activities, and costs associated with operating as a public company. To raise capital, we may sell common stock, convertible securities, or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities, or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our existing stockholders, and new investors could gain rights, preferences, and privileges senior to the holders of our common stock.
Pursuant to the 2020 Plan and the 2019 Plan, our management is authorized to grant stock options to our employees, directors, and consultants.
The number of shares of common stock reserved for issuance under the 2020 Plan increased on January 1, 2026 and shall be cumulatively increased each January 1 thereafter by 5% of the total number of shares of our common stock outstanding on December 31 of the preceding calendar year or a lesser number of shares determined by our board of directors. Unless our board of directors elects not to increase the number of shares available for future grant each year, our stockholders may experience additional dilution, which could cause our stock price to fall.
Additionally, at a special meeting of our stockholders held on March 12, 2025, our stockholders approved an amendment to the 2020 Plan which increased the number of shares of our common stock reserved and available for future issuance under the 2020 Plan by a number of shares of common stock equal to five percent of the total number of shares of common stock that were issued and outstanding immediately following the closing of the Merger.
Sales of a substantial number of shares of our common stock by our existing stockholders in the public market could cause our stock price to fall.
If our stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the trading price of our common stock could decline.
Shares of our common stock may be freely sold in the public market at any time to the extent permitted by Rules 144 and 701 under the Securities Act, or to the extent such shares have already been registered under the Securities Act and are held by non-affiliates of ours. If our stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the trading price of our common stock could decline. In addition, we have filed or intend to file registration statements registering all shares of common stock that we may issue under our equity compensation plans or pursuant to equity awards made to newly hired employees outside of equity compensation plans. These shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.
105
Moreover, in December 2025, we sold to certain institutional investors shares of our common stock and pre-funded warrants in our 2025 Private Placement. We have filed a registration statement on Form S-3 covering the resale of the common stock held by such investors in the 2025 Private Placement and the shares of common stock issuable upon the exercise of the pre-funded warrants issued in the 2025 Private Placement, and we have agreed to keep such registration statement effective until the date the shares covered by it have been sold or can be resold without restriction under Rule 144 of the Securities Act. The sale or resale of these shares in the public market, or the market’s expectation of such sales, may result in an immediate and substantial decline in our stock price. Such a decline will adversely affect our investors and also might make it difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.
Our executive officers, directors and principal stockholder, Samsara LP, have the ability to control or significantly influence all matters submitted to our stockholders for approval.
Our executive officers, directors and principal stockholder, Samsara LP, in the aggregate, beneficially owned approximately 68.0% of our outstanding shares of common stock as of March 31, 2026. As a result, if these stockholders were to choose to act together (or, in the case of Samsara LP, alone), they would be able to control or significantly influence all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these persons, if they choose to act together (or, in the case of Samsara LP, alone), they would be able to control or significantly influence the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of voting power could delay or prevent an acquisition of us on terms that other stockholders may desire. In addition, as a result of this concentration of ownership, there may be a limited number of shares of our common stock that are not held by officers, directors and the principal stockholder, thereby adversely impacting the liquidity of our common stock and potentially depressing the price at which stockholders may be able to sell shares of common stock.
Samsara LP, our principal stockholder, beneficially owns greater than 50% of our outstanding shares of capital stock, which has caused us to be deemed a “controlled company” under the rules of Nasdaq.
Samsara LP controlled approximately 56.3% of the voting power of our capital stock as of March 31, 2026. As a result, Samsara LP owns more than 50% of our outstanding capital stock, and as such, we are a “controlled company” under the rules of Nasdaq. Under these rules, a company of which more than 50% of the voting power is held by an individual, a group or another company is a “controlled company” and, as such, can elect to be exempt from certain corporate governance requirements, including requirements that:
We rely on certain of these exemptions. As a result, our stockholders will not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements.
If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock price and trading volume could decline.
The trading market for our common stock will be influenced by the research and reports that equity research analysts publish about us and our business. Equity research analysts may elect not to provide research coverage of our common stock, and such lack of research coverage may adversely affect the market price of our common stock. In the event we do have equity research analyst coverage, we will not have any control over the analysts or the content and opinions included in their reports. The price of our common stock could decline if one or more equity research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of us or fails to publish reports on us regularly, demand for our common stock could decrease, which in turn could cause our stock price or trading volume to decline.

We have broad discretion in the use of our cash and cash equivalents and may invest or spend the proceeds in ways with which you do not agree and in ways that may not increase the value of your investment.
We have broad discretion over the use of our cash and cash equivalents. You may not agree with our decisions, and our use of our cash and cash equivalents may not yield any return on your investment. Our failure to apply these resources effectively could compromise our ability to pursue our growth strategy and we might not be able to yield a significant return, if any, on our investment of our cash and cash equivalents. You will not have the opportunity to influence our decisions on how to use our cash resources.
General Risk Factors
Changes in tax laws or in their implementation or interpretation could adversely affect our business and financial condition.
Income, sales, use or other tax laws, statutes, rules, or regulations could be enacted or amended at any time, which could affect our business or financial condition, including causing potentially adverse impacts to our effective tax rate, tax liabilities, and cash tax obligations. For example, the IRA was signed into law in August 2022, and the OBBBA was signed into law in July 2025. The IRA introduced new tax provisions, including a one percent excise tax imposed on certain stock repurchases by publicly traded companies. The one percent excise tax generally applies to any acquisition of stock by the publicly traded company (or certain of its affiliates) from a stockholder of the company in exchange for money or other property (other than stock of the company itself), subject to a de minimis exception. Thus, the excise tax could apply to certain transactions that are not traditional stock repurchases. The OBBBA contains numerous tax provisions that we are currently in the process of evaluating, and which may significantly affect our business or financial condition. The recent changes under the OBBBA include tax rate extensions and changes to the business interest deduction limitation, the expensing of domestic research and development expenditures (in contrast to the continued capitalization and amortization of foreign research and development expenditures), the bonus depreciation deduction rules, and the international tax framework. Regulatory guidance under the IRA, the OBBBA, and other tax-related legislation is and continues to be forthcoming, and such guidance could ultimately increase or lessen the impact of these laws on our business and financial condition. In addition, it is uncertain if and to what extent various states will conform to changes to federal tax legislation.
