ORUKA THERAPEUTICS, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Nature of the Business and Basis of Presentation
Background and Basis of Presentation
Oruka Therapeutics, Inc., together with its subsidiary (collectively, the “Company”), is a clinical-stage biopharmaceutical company. The Company is headquartered in Menlo Park, California. The Company is focused on developing novel monoclonal antibody therapeutics for psoriasis (“PsO”) and other inflammatory and immunology (“I&I”) indications.
The condensed consolidated financial statements and accompanying notes reflect the operations of the Company and its wholly-owned subsidiary. Intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements and accompanying notes have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial reporting and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and therefore do not include all information and disclosures normally included in the annual consolidated financial statements. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited financial statements and the related notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 12, 2026 (the “Annual Report”). The information as of December 31, 2025, included in the condensed consolidated balance sheets was derived from the Company’s audited financial statements. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements, and in the opinion of the Company’s management, reflect all adjustments, which include only normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial statements.
The results for the three months ended March 31, 2026 are not necessarily indicative of results that may be expected for the year ending December 31, 2026 or for any other interim period or for any other future year.
Liquidity
As of March 31, 2026, the Company had cash, cash equivalents, and marketable
securities of $
The Company expects that its research and development and general and administrative costs will continue to increase significantly, including in connection with conducting future preclinical activities and clinical trials and manufacturing for its existing product candidates and any future product candidates to support commercialization and providing general and administrative support for its operations, including the costs associated with operating as a public company. 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
There have been no significant changes from the significant accounting policies and estimates disclosed in the Note titled “2. Summary of Significant Accounting Policies” of the Company’s Annual Report. The Company uses the same accounting policies in preparing its quarterly and annual financial statements.
Use of Estimates
The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, assumptions, and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting periods. Significant estimates and assumptions reflected within these condensed consolidated financial statements include but are not limited to research and development expenses and related prepaid or accrued costs and the valuation of stock-based compensation awards and related expenses. The Company bases its estimates on known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates, as there are changes in circumstances, facts, and experience. Actual results could differ materially from those estimates or assumptions.
Recently Adopted Accounting Pronouncements
There have been no recent accounting pronouncements or changes in accounting pronouncements adopted during the three months ended March 31, 2026 that are of significance or potential significance to the Company.
Recently Issued Accounting Pronouncements
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. This ASU requires more detailed disclosures, on an annual and interim basis, about specified categories of expenses (including employee compensation, depreciation, and amortization) included in certain expense captions presented on the face of the income statement. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. This ASU may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the adoption of this ASU on its condensed consolidated financial statements.
3. ATM Offering
On October 3, 2025, the Company entered into a Sales Agreement with
TD Securities (USA) LLC (the “Sales Agreement”), as its sales agent, pursuant to which the Company may issue and sell, from
time to time, shares of common stock for aggregate gross proceeds of up to $

The Company evaluated its securities for credit losses and considered the decline in market value to be primarily attributable to current economic and market conditions and not to a credit loss or other factors. Additionally, the Company does not intend to sell the securities in an unrealized loss position and it is not more likely than not that the Company will be required to sell the securities before recovery of the unamortized cost basis, which may be at maturity. There were no material realized gains or realized losses on marketable securities for the periods presented. Given the Company’s intent and ability to hold such securities until recovery, and the lack of significant change in credit risk of these investments, the Company does not consider these marketable securities to be impaired as of March 31, 2026 and December 31, 2025. As of March 31, 2026 and December 31, 2025, the Company did not record an allowance for credit losses.

Stock-based compensation expense associated with RSUs are based on the fair value of the Company’s common stock on the grant date, which equals the closing market price of the Company’s common stock on the grant date. For RSUs, the Company recognizes compensation expense over the vesting period of the awards that are ultimately expected to vest.

Option Agreements and Paruka Warrant Obligation
As part of the Option Agreements
(defined in Note 10 below), the Company granted warrants to purchase a number of shares equal to
The grant dates for the issuance of warrants were expected to be December 31, 2024 and December 31, 2025 as all terms of the award, including number of shares and exercise price, will be known by all parties. The Company determined that the 2024 and 2025 grants are two separate grants, as there would be no obligation for the 2025 grant had the Company exercised or terminated all of the options under the Option Agreements prior to December 31, 2024. The service inception period for the grant precedes the grant date, with the full award being vested as of the grant date with no post-grant date service requirement. Accordingly, a liability related to the Paruka Warrant Obligation was recorded during the 2024 and 2025 interim periods. The liability is adjusted to fair value at the end of each interim reporting period, with changes in fair value recorded in the consolidated statements of operations as stock-based compensation expenses under research and development expenses.

Overview
We are a clinical-stage biopharmaceutical company focused on developing novel monoclonal antibody therapeutics for psoriasis (“PsO”) and other inflammatory and immunology (“I&I”) indications. Our name is derived from or, for “skin,” and arukah, for “restoration,” and reflects our mission to deliver therapies for chronic skin diseases that provide patients the most possible freedom from their condition. Our strategy is to apply antibody engineering and format innovations to validated modes of action, which we believe will enable us to improve meaningfully upon the efficacy and dosing regimens of standard-of-care medicines while significantly reducing technical and biological risk. Our programs aim to treat and potentially modify disease by targeting mechanisms with proven efficacy and safety involved in disease pathology and the activity of pathogenic tissue-resident memory T cells (“TRMs”).
Our lead program, ORKA-001, is designed to target the p19 subunit of interleukin-23 (“IL-23p19”) for the treatment of PsO. Our co-lead program, ORKA-002, is designed to target interleukin-17A and interleukin-17F (“IL-17A/F”) for the treatment of PsO, hidradenitis suppurativa (“HS”), psoriatic arthritis (“PsA”), and other conditions. These programs each bind their respective targets at high affinity and incorporate half-life extension technology with the aim to increase exposure and decrease dosing frequency. We believe that our focused strategy, differentiated portfolio, and deep expertise position us to set a new treatment standard in large I&I markets with continued unmet need.
Since our inception in February 2024, we have devoted substantially all of our resources to raising capital, organizing and staffing our company, business and scientific planning, conducting discovery and research activities, establishing and protecting our intellectual property portfolio, establishing arrangements with third parties for the manufacture of our programs and component materials, developing and progressing our pipeline, and providing general and administrative support for these operations. We do not have any products approved for sale and have not generated any revenue from product sales. To date, we have funded our operations primarily with proceeds from the issuance of convertible preferred stock, common stock, a convertible note, and pre-funded warrants.
Since our inception, we have incurred significant losses and negative cash flows from our operations. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of any programs we may develop. As of March 31, 2026, we had an accumulated deficit of $221.0 million. For the three months ended March 31, 2026, we had net losses of $31.8 million, and we used net cash of $23.6 million for our operating activities.
We had cash, cash equivalents, and marketable securities of $496.0 million as of March 31, 2026. In addition, in April 2026, we sold 9,660,000 shares of our common stock in an underwritten public offering for gross proceeds of $700.4 million before any underwriting discounts and commissions and related issuance expenses. We expect that our existing cash, cash equivalents, and marketable securities will be sufficient to fund our operating plans for at least twelve months from the date of filing of this Quarterly Report. We expect to continue to incur substantial losses for the foreseeable future, and our transition to profitability will depend upon successful development, approval and commercialization of our product candidates and upon achievement of sufficient revenues to support our cost structure.

Our Portfolio and Development Plans
ORKA-001
ORKA-001 is a high affinity, extended half-life monoclonal antibody (“mAb”) designed to target IL-23p19. IL-23 is a pro-inflammatory cytokine that plays a critical role in the proliferation and development of T helper 17 (“Th17”) cells, which are the primary drivers of several autoimmune and inflammatory disorders, including PsO. IL-23 is composed of two subunits: a p40 subunit that is shared with IL-12 and a p19 subunit that is specific to IL-23. First-generation IL-23 antibodies bound p40 and inhibited both IL-12 and IL-23 signaling, while more recent IL-23 antibodies targeting the p19 subunit have shown improved efficacy and safety. Based on clinical evidence, we believe that ORKA-001 could achieve higher response rates than established therapies in PsO while requiring less frequent dosing and maintaining the favorable safety profile of therapies targeting IL-23p19.
ORKA-001 is engineered with YTE half-life extension technology, a specific three amino acid change in the fragment crystallizable (“Fc”) domain to modify the pH-dependent binding to the neonatal Fc receptor (“FcRn”). As a result, it has a pharmacokinetic profile designed to support a subcutaneous (“SQ”) injection as infrequently as once or twice per year. In addition, emerging evidence suggests that IL-23 blockade can modify the disease biology of PsO, possibly leading to durable remissions and preventing the development of PsA. We believe that the expected characteristics of ORKA-001 increase its potential to deliver these disease-modifying benefits.
We initiated a Phase 1 trial of ORKA-001 in the fourth quarter of 2024. In September 2025, we announced interim results and updated those results in April 2026. The data showed that ORKA-001 has a human half-life of approximately 100 days and was well tolerated at all dose levels, with a favorable safety profile consistent with the anti-IL-23 class. The Phase 1 trial data support that a single 600mg dose maintained ORKA-001 concentrations well above effective trough levels through Week 52, the last timepoint evaluated with sustained inhibition of IL-23 pathway signaling observed throughout that time period.
In the third quarter of 2025, we commenced dosing in a Phase 2a clinical trial of ORKA-001 in patients with moderate-to-severe PsO (also known as “EVERLAST-A”). EVERLAST-A enrolled 84 patients randomized 3:1 to receive 600 mg of ORKA-001 at Weeks 0 and 4 or matching placebo. At Week 28, patients who have achieved PASI 100 will be randomized 2:1 to an arm where either (1) they do not receive another dose until disease recurrence (to evaluate the possibility of both yearly dosing and extended off-treatment remissions) or (2) they receive 300 mg ORKA-001 every six months. We announced Week 16 data for all patients in April 2026. 40 of 63 participants (63.5%) treated with ORKA-001 achieved the primary endpoint of PASI 100, a 100% reduction from baseline in the Psoriasis Area and Severity Index (“PASI”), at Week 16 and identical results were observed for Investigator’s Global Assessment (“IGA”) 0. Other key secondary endpoints included PASI 90 at Week 16, achieved by 83% of participants, and IGA 0/1 at Week 16, achieved by 84% of participants. ORKA-001 was well tolerated with a safety profile consistent with prior IL-23p19 inhibitors. There were no serious treatment-emergent adverse events (“TEAEs”) and only one severe TEAE, which occurred in the placebo group. Additionally, there were no injection site reactions. We plan to share longer-term data, including Week 28 for all patients and 52-week follow-up for a portion of the cohort, in the second half of 2026.
Additionally, the first patients were dosed in EVERLAST-B in December 2025. EVERLAST-B is designed to enroll approximately 160 patients into a dose-ranging Phase 2b trial of ORKA-001 in patients with moderate-to-severe PsO and will evaluate three dose levels of ORKA-001: 37.5 mg at Week 0, 300 mg at Weeks 0 and 4, and 600 mg at Weeks 0 and 4, versus placebo. The primary endpoint is PASI 100 at Week 16. At Week 28, patients who have achieved PASI 100 will be re-randomized 1:1 to either a 600 mg dose once-yearly or placebo. Patients who have not achieved PASI 100 at Week 28 will receive a 300 mg dose every six months. Building on EVERLAST-A, this design will further test the potential for ORKA-001 to achieve yearly dosing, higher efficacy and extended off-treatment remissions. We expect to announce data from EVERLAST-B in 2027.
Based on recent precedent in PsO, we anticipate that the overall development program, from first-in-human studies through biologics license application (“BLA”) submission, could take as little as six to seven years, based on averages observed for recently approved medicines. However, we have no control over the duration of the United States Food and Drug Administration (“FDA”) review process, and the actual timeline may vary.
ORKA-002
ORKA-002 is a high affinity, extended half-life mAb designed to target IL-17A and IL-17F (“IL-17A/F”). IL-17 inhibition has become central to the treatment of psoriatic diseases, including PsO and PsA, and has also shown efficacy in other I&I indications, such as HS and axial spondyloarthritis (“axSpA”). More recently, the importance of inhibiting the IL-17F isoform along with IL-17A has become appreciated, and dual blockade with the recently approved therapy Bimzelx (bimekizumab) has led to higher response rates in patients than blockade of IL-17A alone. ORKA-002 is designed to bind IL-17A/F at similar epitopes, or binding sites, and affinity ranges as bimekizumab, but incorporates half-life extension technology that could enable more convenient dosing intervals.
24
In January 2026, we announced interim findings from the Phase 1 trial of ORKA-002 in healthy volunteers. The results showed that ORKA-002 has a half-life of approximately 75-80 days, which supports the potential for twice-yearly maintenance dosing in PsO and quarterly maintenance dosing in HS. Single doses of ORKA-002 demonstrated potent and sustained inhibition of IL-17 signaling in an ex vivo assay through 24 weeks. ORKA-002 was well tolerated at all dose levels, with a favorable safety profile consistent with the anti-IL-17 class. The trial remains blinded, and as of January 6, 2026, which was the data cutoff date, all subjects remained on trial.
Based on these Phase 1 results, we initiated ORCA-SURGE, a Phase 2 trial of ORKA-002 in patients with moderate-to-severe PsO, in February 2026. ORCA-SURGE is designed to enroll approximately 160 patients randomized 1:1:1:1 to receive 40 mg, 160 mg or 320 mg of ORKA-002 at Weeks 0 and 4, or matching placebo. The primary endpoint is PASI 100 at Week 16. Maintenance dosing will evaluate the potential for twice-yearly dosing with ORKA-002. We expect to announce data from ORCA-SURGE in 2027. Moreover, we also expect to initiate ORCA-SPLASH, a Phase 2 trial of ORKA-002 in patients with HS in the second half of 2026.
Additional Pipeline Program
We have a third program, ORKA-003, designed to target an undisclosed pathway. Our strategy as a company is to remain highly focused on I&I diseases, and specifically on inflammatory dermatology conditions. Our third program provides the potential for indication expansion beyond PsO and may create combination opportunities with our more advanced programs.
Option Agreements and License Agreements – Paragon Therapeutics
In March 2024, we entered into two Antibody Discovery and Option Agreements with Paragon and Paruka Holding, LLC (“Paruka”) (each, an “Option Agreement”), pursuant to which we initiated certain research programs with Paragon focusing on discovering, generating, identifying and/or characterizing antibodies directed to a particular target, including for IL-23 and IL-17A/F for ORKA-001 and ORKA-002, respectively. In September 2024, we exercised our exclusive option to acquire certain rights to ORKA-001, and in December 2024, we entered into a corresponding license agreement with Paragon pursuant to which Paragon granted us a royalty-bearing, world-wide, exclusive license to develop, manufacture, commercialize or otherwise exploit certain antibodies and products targeting IL-23 in all fields other than the field of inflammatory bowel disease. In December 2024, we exercised our exclusive option to acquire certain rights to ORKA-002, and in February 2025, we entered into the corresponding license agreement with Paragon pursuant to which Paragon granted us a royalty-bearing, world-wide, exclusive license to develop, manufacture, commercialize or otherwise exploit certain antibodies and products targeting IL-17A/F in all fields (collectively, the “License Agreements”).
Pursuant to each of the License Agreements, Paragon has agreed not to conduct any new campaigns that generate anti-IL-23 monospecific antibodies or anti-IL-17A/F monospecific antibodies in the respective agreed-upon fields. Each of the ORKA-001 and ORKA-002 License Agreements may be terminated on 60 days’ notice to Paragon, on material breach without cure, and on a party’s insolvency or bankruptcy to the extent permitted by law.
Pursuant to the terms of each of the License Agreements, we are obligated to pay Paragon non-refundable milestone payments of up to $12.0 million under each respective agreement upon the achievement of certain clinical development milestones and up to $10.0 million under each respective agreement upon the achievement of certain regulatory milestones. In addition, we are obligated to pay Paragon a low single-digit percentage royalty for antibody products for each of ORKA-001 and ORKA-002. For each of the License Agreements, the royalty term ends on the later of (i) the last-to-expire licensed patent or our patent directed to the manufacture, use or sale of a licensed antibody in the country at issue or (ii) 12 years from the date of first sale of our product. There is also a royalty step-down if there is no Paragon patent in effect during the royalty term for each program.
In December 2025, we entered into an additional option agreement for an antibody with Paragon and Paruka to enter into a license agreement, which we exercised in December 2025. Per the terms of this option agreement, once we enter into the corresponding license agreement, we will be required to make non-refundable milestone payments to Paragon of up to $12.0 million under the agreement upon the achievement of certain clinical development milestones, up to $10.0 million under the agreement upon the achievement of a certain regulatory milestone, as well as a low single-digit percentage royalty for antibody products beginning on the first commercial sale. As of March 31, 2026, we have not entered into a license agreement with Paragon and Paruka related to this additional option agreement.
During the quarter ended March 31, 2026, we incurred and expensed a milestone of $3.0 million related to the dosing of the first patient in a Phase 2 trial for the ORKA-002 License Agreement. Pursuant to the License Agreements, as of March 31, 2026, we have incurred and expensed milestone payments of $7.0 million for each of ORKA-001 and ORKA-002.

Components of Results of Operations
Revenue
To date, we have not generated revenue from any sources, including product sales, and do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts for our product candidates are successful and result in regulatory approval, we may generate revenue in the future from product sales or payments from future collaboration or license agreements that we may enter into with third parties, or any combination thereof. We cannot predict if, when, or to what extent we will generate revenue from the commercialization and sale of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.
Operating Expenses
Research and Development
Research and development expenses consist primarily of costs incurred in connection with the development and research of our programs. These expenses include:
| ● | costs of funding research performed by third parties that conduct research and development activities on our behalf; |
| ● | costs incurred, and milestone payments under license and option agreements; |
| ● | expenses incurred in connection with continuing our current research programs and discovery-phase development of any programs we may identify, including under future agreements with third parties, such as consultants and contractors; |
| ● | expenses incurred under agreements with contract research organizations (“CROs”), contract manufacturing organizations (“CMOs”), and with clinical trial sites that conduct research and development activities on our behalf; |
| ● | the cost of development and validating our manufacturing process for use in our preclinical studies and current and future clinical trials; |
| ● | personnel-related expenses, including salaries, bonuses, employee benefits, travel, and stock-based compensation expense; and |
| ● | allocated human resource costs, information technology costs, and facility-related costs, including rent, maintenance, utilities, and depreciation for our leased office space. |
We expense research and development costs as incurred. Non-refundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed, or when it is no longer expected that the goods will be delivered or the services rendered. Our primary focus since inception has been the identification and development of our pipeline programs. Our research and development expenses primarily consist of external costs. See Note 10 to the condensed consolidated financial statements included in Part I - Item 1 of this Quarterly Report for further details on the Option Agreements.
26
We expect our research and development expenses will increase substantially for the foreseeable future as we continue to invest in research and development activities related to the continued development of our programs, developing any future programs, including investments in manufacturing, as we advance any program we may identify and continue to conduct clinical trials. The success of programs we may identify and develop will depend on many factors, including the following:
| ● | timely and successful completion of preclinical studies and clinical trials; |
| ● | effective investigational new drug (“IND”) or comparable foreign applications that allow commencement of our planned clinical trials or future clinical trials for any programs we may develop; |
| ● | successful enrollment and completion of clinical trials; |
| ● | positive results from our clinical trials that support a finding of safety and effectiveness, acceptable pharmacokinetics profile, and an acceptable risk-benefit profile in the intended populations; |
| ● | receipt of marketing approvals from applicable regulatory authorities; |
| ● | establishment of arrangements through our own facilities or with third-party manufacturers for clinical supply and, where applicable, commercial manufacturing capabilities; and |
| ● | maintenance of a continued acceptable safety, tolerability, and efficacy profile of any programs we may develop following approval. |
Any changes in the outcome of any of these variables with respect to the development of programs that we may identify could mean a significant change in the costs and possible delays in timing associated with the development of such programs. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a program, or if we experience significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time on the completion of clinical development. We may never obtain regulatory approval for any of our programs.
General and Administrative
General and administrative expenses consist primarily of personnel-related expenses, including salaries, bonuses, employee benefits, travel, and stock-based compensation, for our executive and other administrative personnel. Other significant general and administrative expenses include legal services, including intellectual property and corporate matters; professional fees for accounting, auditing, tax, insurance, and allocated human resource costs, information technology costs, and facility-related costs, including rent, utilities, maintenance, and depreciation for our leased office space.
We expect our general and administrative expenses will increase substantially for the foreseeable future as we anticipate an increase in our personnel headcount to support the expansion of research and development activities, as well as to support our operations generally. We also expect to continue to incur significant expenses associated with being a public company, including costs related to accounting, audit, legal, regulatory, and tax-related services associated with maintaining compliance with applicable Nasdaq and SEC requirements; director and officer insurance costs; and investor and public relations costs. We also expect to incur additional intellectual property-related expenses as we file patent applications to protect innovations arising from our research and development activities.

Other Income (Expense), Net
Total other income (expense), net, consists of interest earned on our cash, cash equivalents, and marketable securities, and foreign currency transactions gains and losses.

Research and development expenses increased by $9.2 million, from $19.9 million for the three months ended March 31, 2025 to $29.1 million for the three months ended March 31, 2026.
External research and development expenses, including CROs, CMOs and other third-party preclinical studies and clinical trials expenses increased by $4.7 million, from $13.6 million for the three months ended March 31, 2025 to $18.3 million for the three months ended March 31, 2026. The increase is primarily related to increased CMO product development and manufacturing expenses, an increase in our CRO expenses related to our ongoing clinical trials, and $3.0 million milestone pursuant to ORKA-002 License Agreement with Paragon related to the dosing of the first patient in a Phase 2 trial during the three months ended March 31, 2026.
Personnel-related expenses, excluding stock-based compensation, increased by $3.6 million, from $2.5 million for the three months ended March 31, 2025 to $6.1 million for the three months ended March 31, 2026, as we continue hiring employees in our research and development organization. Stock-based compensation expense increased by $0.6 million, from $3.0 million for the three months ended March 31, 2025 to $3.6 million for the three months ended March 31, 2026. The increase in stock-based compensation expense is primarily related to a $2.0 million increase related to employee awards due to an increase in research and development headcount, partially offset by a $1.4 million decrease in Paruka warrant liability under the Option Agreements.
Other research and development expenses increased by $0.3 million, from $0.8 million for the three months ended March 31, 2025 to $1.2 million for the three months ended March 31, 2026, primarily due to increases to facilities and allocated overhead expenses as we commenced using our leased Waltham office from April 2025, as well as an increase in our research and development employee count.

General and administrative expenses increased by $2.1 million, from $5.2 million for the three months ended March 31, 2025 to $7.3 million for the three months ended March 31, 2026.
Personnel-related expenses increased by $1.9 million, from $3.6 million for the three months ended March 31, 2025 to $5.5 million for the three months ended March 31, 2026, as a result of continued hiring of executives and administrative employees. Stock-based compensation expense increased by $1.5 million, from $1.9 million for the three months ended March 31, 2025 to $3.4 million for the three months ended March 31, 2026 due to additional general and administrative headcount.
Expenses related to professional and consulting services increased by $0.2 million, from $1.4 million for the three months ended March 31, 2025 to $1.6 million for the three months ended March 31, 2026, due to higher spending on legal and other professional services.
Other general and administrative expenses remained relatively consistent year over year.
Total Other Income (Expense), Net
Interest income from cash equivalents and marketable securities was $4.6 million and $4.1 million for the three months ended March 31, 2026 and 2025, respectively. The increase was primarily due to interest earned on higher cash and marketable securities balances.
Liquidity and Capital Resources
As of March 31, 2026, we had $496.0 million of cash, cash equivalents, and marketable securities.
Since our inception, we have incurred significant operating losses and negative cash flow from operations. We expect to incur significant expenses and operating losses for the foreseeable future as we continue the preclinical and clinical development of our programs and our early-stage research activities. We have not yet commercialized any products, and we do not expect to generate revenue from sales of products for several years, if at all. Through March 31, 2026, we had funded our operations primarily with proceeds from issuances of convertible preferred stock, common stock, a convertible note, and pre-funded warrants.
In October 2025, we entered into a Sales Agreement with TD Securities (USA) LLC (the “Sales Agreement”), as our sales agent, pursuant to which we may issue and sell, from time to time, shares of common stock for aggregate gross proceeds of up to $200.0 million under an at-the-market (“ATM”) equity offering program. We are not obligated to make any sales of shares under the Sales Agreement. During the three months ended March 31, 2026, we issued and sold an aggregate of 1,167,895 shares of the Company’s common stock pursuant to the ATM offering program for total net proceeds of $38.9 million after deducting sales agents’ commissions. In addition, in April 2026, we sold 9,660,000 shares of our common stock in an underwritten public offering for gross proceeds of $700.4 million before any underwriting discounts and commissions and related issuance expenses.
Our primary use of cash is to fund the development of our product candidates and advance our pipeline. This includes both the research and development costs and the general and administrative expenses required to support those operations. Since we are a clinical stage biopharmaceutical company, we have incurred significant operating losses since our inception and we anticipate such losses, in absolute dollar terms, to increase as we continue to pursue clinical development of our product candidates, prepare for the potential commercialization of our product candidates, and expand our development efforts in our pipeline of nonclinical candidates. We expect that our existing cash, cash equivalents, and marketable securities will be sufficient to fund our operating plans for at least twelve months from the date of filing of this Quarterly Report. We will need to secure additional financing in the future to fund additional research and development, and before a commercial drug can be produced, marketed, and sold. If we are unable to obtain additional financing or generate license or product revenue, the lack of liquidity could have a material adverse effect on our company.

| Net cash provided by financing activities | 40,600 | — | ||||||
| Net increase in cash and cash equivalents | $ | 2,585 | $ | 21,997 | ||||
Operating Activities
For the three months ended March 31, 2026, net cash used in operating activities was $23.6 million, which was primarily attributable to a net loss of $31.8 million, partially offset by net non-cash charges of $6.7 million and net cash used by changes in our operating assets and liabilities of $1.5 million. Net cash used by changes in our operating assets and liabilities were primarily comprised of an increase of $3.0 million in related party accounts payable and other current liabilities and an increase of $0.5 million in prepaid expenses and other current assets, partially offset by a decrease of $1.3 million in accrued expenses and other liabilities and a decrease of $0.5 million in accounts payable. Net non-cash charges primarily comprised of $7.0 million in stock-based compensation expense, partially offset by $0.4 million in net accretion of premiums and discounts on marketable securities.
For the three months ended March 31, 2025, net cash used in operating activities was $20.9 million, which was primarily attributable to a net loss of $21.0 million and net changes in our operating assets and liabilities of $3.0 million, partially offset by net non-cash charges of $3.1 million. Net changes in our operating assets and liabilities were primarily comprised of a decrease of $5.2 million in related party accounts payable and other current liabilities and an increase of $2.3 million in accrued expenses and other current liabilities. Net non-cash charges primarily comprised of $4.9 million in stock-based compensation expense, partially offset by $1.8 million in net accretion of premiums and discounts on marketable securities.
Investing Activities
For the three months ended March 31, 2026, net cash used in investing activities was $14.4 million, which included $90.8 million in purchases of marketable securities, $0.1 million in purchases of property and equipment, partially offset by $76.5 million in proceeds from maturities of marketable securities.
For the three months ended March 31, 2025, net cash provided by investing activities was $42.9 million, which included $87.2 million in proceeds from maturities of marketable securities, partially offset by $44.3 million in purchases of marketable securities.
Financing Activities
For the three months ended March 31, 2026, net cash provided by financing activities was $40.6 million due to $38.9 million of net proceeds from the ATM offering program and $1.7 million of proceeds from the issuance of shares of common stock in connection with exercises of stock options and employee warrants.
For the three months ended March 31, 2025, no cash was used in or provided by financing activities.
31
Contractual Obligations and Commitments
We enter into contracts in the normal course of business with CROs, CMOs and with other vendors for preclinical research studies, clinical trials, manufacturing, and other services and products for operating purposes. These contracts generally provide for termination on notice or may have a potential termination fee if the contract is cancelled within a specified time, and therefore, are cancelable contracts. We do not expect any such contract terminations and did not have any non-cancellable obligations under these agreements as of March 31, 2026. See Notes 10 and 11 to the condensed consolidated financial statements included in Part I - Item 1 of this Quarterly Report for further information on our contractual lease obligations for our headquarters in Menlo Park, California, and our office in Waltham, Massachusetts, and other commitments, including the commitments under the Option and License Agreements.
Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us 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 revenues recognized and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe 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. Actual results may differ from these estimates under different assumptions or conditions.
Our significant accounting policies are described in more detail in Note 2 to our condensed consolidated financial statements included in Part I - Item 1 of this Quarterly Report. During the three months ended March 31, 2026, there were no changes to our critical accounting policies and significant judgments and estimates as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025.
Off-Balance Sheet Arrangements
As of March 31, 2026, we did not have any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are a smaller reporting company, as defined by Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and in Item 10(f)(1) of Regulation S-K, and are not required to provide the information under this item.
32
Item 4. Controls and Procedures
Management’s Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
As required by Rule 13a-15(b) or Rule 15d-15(b) promulgated by the SEC under the Exchange Act, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on the foregoing, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Our management, including our principal executive officer and principal financial officer, believes that our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
33
Part II - Other Information
Item 1. Legal Proceedings
From time to time, we may become involved in legal proceedings relating to claims arising from the ordinary course of business. Our management believes that there are currently no claims or actions pending against us, the ultimate disposition of which could reasonably be expected to have a material adverse effect on our results of operations, financial condition or cash flows.
Item 1A. Risk Factors
Risk Factors Summary
We are subject to a number of risks that could harm our business, financial condition, results of operations and/or growth prospects or cause our actual results to differ materially from those contained in forward-looking statements we have made in this Quarterly Report and those we may make from time to time. The success of our product candidates will depend on a variety of factors. We do not have complete control over many of these factors, including certain aspects of clinical development and the regulatory submission process, potential threats to our intellectual property rights and the manufacturing, marketing, distribution and sales efforts of any current or future collaborator. In addition, some of the factors, events and contingencies discussed below may have occurred in the past, but the disclosures below are not representations as to whether or not the factors, events or contingencies have occurred in the past and instead reflect our beliefs and opinions as to the factors, events, or contingencies that could materially and adversely affect us in the future.
The summary below is not exhaustive and is qualified by reference to the full set of risk factors set forth in Item 1A “Risk Factors” of this Quarterly Report. Please carefully consider all the information in this Quarterly Report, including the full set of risks set forth in the “Risk Factors” section, and in our other filings with the U.S. Securities and Exchange Commission (the “SEC”) before making an investment decision regarding the Company.
Risks Related to Our Financial Condition and Capital Requirements
| ● | We are a clinical stage biopharmaceutical company with a limited operating history on which to assess our business. Our clinical trials remain ongoing and we have no products approved for commercial sale. | |
| ● | We have historically incurred losses and we anticipate that we will continue to incur losses for the foreseeable future. | |
| ● | We have never generated revenue from product sales and may never be profitable. | |
| ● | We may not be able to raise the capital that we need to support our business 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. |
Risks Related to Clinical Development, Regulatory Approval and Commercialization
| ● | Drug development and obtaining and maintaining regulatory approval for drug products is costly, time-consuming, and highly uncertain. | |
| ● | We are substantially dependent on the success of our two most advanced programs, ORKA-001 and ORKA-002. We may not achieve our projected development goals in the time frames we announce and expect, or at all. | |
| ● | We face competition from entities that have developed or may develop programs for the diseases addressed by our product candidates. |
34
Risks Related to Government Regulations
| ● | We may not be able to meet requirements for the chemistry, manufacturing and control of our programs. |
| ● | The U.S. Food and Drug Administration (“FDA”) and comparable foreign regulatory approval processes are lengthy and time consuming and we may not be able to obtain or may be delayed in obtaining regulatory approvals for our product candidates. Moreover, even if we obtain regulatory approval, we will be subject to ongoing regulatory obligations. |
Risks Related to Our Intellectual Property
| ● | Our ability to obtain and protect our patents and other proprietary rights is uncertain and we may fail in obtaining or maintaining necessary rights to our programs. | |
| ● | We may become subject to claims challenging the inventorship or ownership of our intellectual property and may be subject to patent infringement claims or may need to file such claims. | |
| ● | Our technology licensed from third parties may be subject to retained rights. |
Risks Related to Our Reliance on Third Parties
| ● | We currently rely on agreements with third parties to develop our product candidates. Our business could be negatively impacted if we are unable to maintain these arrangements or if these arrangements are not successful, for example, if such third parties fail to carry out their contractual duties. | |
| ● | Our third-party manufacturing partners and manufacturing sites may fail to perform adequately in their efforts to support the manufacture of our product candidates and we may need to switch or create third-party manufacturer redundancies. |
Risks Related to Employee Matters, Managing Growth, Other Risks Related to Our Business, and Risks Related to Owning Our Common Stock
| ● | Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business may not grow at similar rates, or at all. | |
| ● | Our business is dependent on key personnel, and we may be harmed if we cannot recruit and retain highly qualified personnel to successfully implement our business strategies. | |
| ● | Our business could be adversely affected by macroeconomic or geopolitical conditions. | |
| ● | Future sales and issuances of equity and debt could result in additional dilution to our stockholders and could cause our stock price to decline. | |
| ● | Future sales of shares, or the anticipation of such sales, by existing stockholders could cause our stock price to decline. |

Risk Factors
Risks Related to Our Financial Condition and Capital Requirements
We are a clinical stage biopharmaceutical company with a limited operating history on which to assess our business; our clinical trials are ongoing, we have no products approved for commercial sale, we have historically incurred losses, and we anticipate that we will continue to incur significant losses for the foreseeable future. Moreover, we have never generated revenue from product sales and may never be profitable.
We are a clinical stage biopharmaceutical company with a limited operating history. We will need to raise substantial additional capital to continue to fund our operations in the future. We have based our estimates on assumptions that may prove to be wrong and we could exhaust our available financial resources sooner than we currently anticipate. We have devoted substantially all of our financial resources to identifying, acquiring, and developing our product candidates, organizing and staffing our company, and providing general and administrative support for our operations.
Additional capital may not be available in sufficient amounts or on reasonable terms, if at all. The current market environment for small and midcap biotechnology companies and broader macroeconomic factors may preclude us from successfully raising additional capital on the timeline we require. For example, escalating geopolitical tensions, elevated interest rates, and economic and regulatory uncertainty have caused market volatility. Such volatility can have an adverse effect on the ability to raise capital, particularly in the biotechnology and biopharmaceutical industries. In addition, it may be difficult for us to raise additional capital if we experience any issues that delay or prevent the regulatory approval or our ability to commercialize any of our product candidates.
Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We expect our losses to increase as our product candidates enter advanced clinical trials. It may be several years, if ever, before we complete pivotal clinical trials or have a product candidate approved for commercialization. We expect to invest significant funds into the research and development of our programs to determine the potential to advance product candidates to regulatory approval. If we obtain regulatory approval to market a product candidate, our future revenue will depend upon the size of approved markets, and our ability to achieve sufficient market acceptance, pricing, coverage and adequate reimbursement from third-party payors, and adequate market share for our products. However, even if we obtain adequate market share for our products, we may never become profitable despite obtaining such market share and acceptance of our products.
We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future and our expenses will increase substantially if and as we:
| ● | continue the clinical development of our product candidates, including advancing our product candidates into larger, more expensive trials; | |
| ● | progress our chemistry, manufacturing and control development, registration, and validation, including the manufacture of our product candidates by third parties, including increasing volumes manufactured by third parties; | |
| ● | continue efforts to discover and develop new product candidates, including initiating preclinical studies or clinical trials; | |
| ● | seek regulatory and marketing approvals and reimbursement for our product candidates; | |
| ● | establish a sales, marketing, and distribution infrastructure to commercialize any products for which we may obtain marketing approval and market for ourselves; | |
| ● | make milestone, royalty, or other payments under third-party license agreements; | |
| ● | seek to maintain, protect, and expand our intellectual property portfolio; and | |
| ● | experience any delays or encounter issues with the development and potential regulatory approval of our product candidates such as safety issues, manufacturing delays, clinical trial delays, longer follow-up for planned studies or trials, additional major studies or trials, or supportive trials necessary to support marketing approval. |

If we are unable to raise additional capital when required or on acceptable terms, we may be required to curtail our product development activities and other activities commensurate with the magnitude of the shortfall and our product development activities may cease altogether, which could materially harm our business, financial condition, and results of operations. To the extent that the costs of our activities exceed our current estimates and we are unable to raise sufficient additional capital to cover such costs, we will need to reduce operating expenses, sell assets, enter into strategic transactions, or effect a combination of the above. No assurance can be given that we will be able to enter into any of such transactions on acceptable terms, if at all. Any of the following events could have a material adverse effect on our business, operating results, and prospects:
| ● | a delay, scaling back, or discontinuation of the development or commercialization of our product candidates; |
| ● | seeking strategic partnerships, or amending existing partnerships, for research and development programs at an earlier stage than otherwise would be desirable or that we otherwise would have sought to develop independently, or on terms that are less favorable than might otherwise be available in the future; |
| ● | disposal of technology assets, or the relinquishing or licensing of assets on unfavorable terms, of our rights to technologies or any of our product candidates that we otherwise would seek to develop or commercialize ourselves; |
| ● | pursuing the sale of the company to a third party at a price that may result in a loss on investment for our stockholders; or |
| ● | filing for bankruptcy or ceasing operations altogether. |
Even if we are successful in raising additional capital, the amount of capital we raise may be limited or restricted due to investor demand, market conditions, or other factors.
Raising additional capital may cause dilution to our stockholders, restrict our operations, or require us to relinquish rights.
To the extent that we raise additional capital through the sale of equity securities or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of holders of our common stock. 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, making capital expenditures, or declaring dividends. For example, most recently, in April 2026, we entered into an underwriting agreement, pursuant to which we issued and sold 9,660,000 shares of common stock for a gross proceeds of $700.4 million before any underwriting discounts and commissions and related issuance expenses. We have granted the underwriters a 30-day option to purchase 1,449,000 additional shares at a price of $72.50 per share, less underwriting discounts and commissions. In addition, in October 2025, we entered into a sales agreement with TD Securities (USA) LLC acting as our sales agent pursuant to which we may issue and sell shares of our common stock from time to time through an at-the-market equity offering program, for aggregate gross proceeds of up to $200.0 million, under which we have sold shares of our common stock resulting in net proceeds of $38.9 million as of March 31, 2026. Previously, in September 2025, we entered into a Securities Purchase Agreement whereby the investors purchased shares of our common stock and pre-funded warrants for aggregate net proceeds of approximately $169.6 million.
Moreover, if we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our research programs or product candidates or grant licenses on terms that may not be favorable to us.
Risks Related to Clinical Development, Regulatory Approval and Commercialization
We face competition from entities that have developed or may develop programs for the diseases addressed by our product candidates.
The development and commercialization of drugs is highly competitive. If approved, our product candidates will face significant competition and our failure to effectively compete may prevent us from achieving significant market penetration. Many of the companies with which we are currently competing or will compete against in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, clinical trials, regulatory approvals, and marketing than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industry may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in establishing clinical trial sites, recruiting participants for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our product candidates.
37
Our competitors have developed, are developing, or may develop programs and processes that compete with ours. Our success will depend partially on our ability to develop and commercialize products that have a competitive safety, efficacy, dosing and/or presentation profile. Our commercial opportunity and success may be reduced or eliminated if competing products are safer, more effective, have a more attractive dosing profile or presentation, or are less expensive than our products, or if biosimilars enter the market and achieve broader or more rapid market acceptance than our products.
Our product candidates may fail in development or suffer delays. We depend on the successful initiation and completion of clinical trials for our product candidates to advance our product development plans.
We expect it will be many years before we can obtain regulatory approval for and commercialize any product candidate, if ever. Clinical testing is expensive, difficult to design and implement, and can take years to complete and is uncertain as to outcome. A failure of one or more of our clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. 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 for their products.
We may experience a number of events affecting our product development timeline, including the following:
| ● | Our clinical trials may fail to show safety or efficacy, show meaningful improvement in efficacy or convenience compared to competitors, produce negative or inconclusive results, or our product candidates may have undesirable side effects or unexpected characteristics. We may decide, or regulators may require additional preclinical studies or clinical trials or we may decide to abandon a product development program altogether. |
| ● | The supply or quality of our clinical trial materials or other materials necessary to conduct clinical trials of our product candidates may be insufficient, unsafe or inadequate. |
| ● | Regulators, Institutional Review Boards (“IRBs”), the FDA, or ethics committees may not authorize us or our investigators to commence or conduct a clinical trial at one or more prospective trial sites; or may require that we or our investigators materially modify, suspend or terminate clinical research or trials for various reasons, including noncompliance with regulatory requirements or a finding that the participants in our trials are being exposed to unacceptable health risks. |
| ● | We may fail to establish an appropriate safety profile for a product candidate based on clinical or preclinical data as well as data emerging from other therapies in the same class as our product candidates. |
| ● | The number of subjects required for clinical trials of any product candidates may be larger than we anticipate, especially if regulatory bodies require completion of non-inferiority or superiority trials. |
| ● | Enrollment in our clinical trials may be slower than we anticipate or subjects may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate. |
| ● | Trial conduct or data analysis errors may occur, including, but not limited to, failure by investigators or participants to adhere to the study protocol or data entry and/or labeling errors. |
| ● | We may experience delays in reaching, or fail to reach, agreement on acceptable terms with prospective trial sites and/or contract research organizations. |
38
| ● | Our third-party contractors or clinical trial sites may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial, which may require that we add new clinical trial sites or investigators and could potentially complicate the analysis of data or affect our product development timeline. |
| ● | The cost of clinical trials of any of our programs may be greater than we anticipate. |
| ● | Reports from clinical testing of other therapies may raise safety or efficacy concerns about our programs. |
| ● | The FDA or other regulatory authorities may require us to submit additional data or impose other requirements and our product development timeline may be adversely affected. | |
| ● | Even if we or an existing or future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. |
If our clinical trials do not produce favorable results, our ability to obtain regulatory approval for our product candidates will be adversely impacted. Moreover, the combined data from our trials may be inconclusive or may not be sufficient to ultimately gain marketing approval from the FDA or other regulatory authorities. There are equivalent processes and risks applicable to clinical trial applications in other countries outside of the United States, including the European Union (“EU”).
In addition, in part due to the competitive landscape for immunology and inflammation (commonly referred to as “I&I”) indications, we may also face increased competition for clinical trial enrollment. Clinical trial enrollment will depend on many factors, including if potential clinical trial participants choose to undergo treatment with approved products or enroll in competitors’ clinical trials for programs that are under development for the same indications as our programs. An increase in the number of approved products for the indications we are targeting with our programs may further exacerbate this competition. Our inability to enroll a sufficient number of participants could, among other things, delay our development timeline, which may further harm our competitive position and have an adverse effect on our business and operations.
We are substantially dependent on the success of our two most advanced programs, ORKA-001 and ORKA-002, and our clinical trials of such programs may not be successful.
Our future success is substantially dependent on our ability to develop and timely obtain marketing approval for, and then successfully commercialize, our two most advanced programs, ORKA-001 and ORKA-002. We are investing the majority of our efforts and financial resources into the research and development of these programs. Our Phase 1 clinical trial of ORKA-001 in healthy volunteers is fully enrolled and is ongoing for purposes of continued patient follow-up and data collection, and remains blinded. Our Phase 2a clinical trial of ORKA-001 in patients with moderate-to-severe psoriasis (“PsO”) remains ongoing and we commenced dosing in a dose-ranging Phase 2b trial of ORKA-001 in moderate-to-severe PsO in the fourth quarter of 2025.
Our Phase 1 clinical trial of ORKA-002 in healthy volunteers is fully enrolled and remains ongoing for purposes of continued patient follow-up and data collection, and remains blinded. In addition, we commenced a Phase 2 clinical trial of ORKA-002 in patients with moderate-to-severe PsO in February 2026 and plan to initiate a Phase 2 clinical trial of ORKA-002 in hidradenitis suppurativa (“HS”) in the second half of 2026.
Currently, we believe that the success of our programs is dependent on our product candidates demonstrating a longer half-life in humans than monoclonal antibodies currently marketed and in development as we believe this longer half-life has the potential to result in a more favorable dosing schedule for our product candidates, assuming they successfully complete clinical development and obtain marketing approval. To the extent we do not observe this extended half-life, it would significantly and adversely affect the clinical and commercial potential of our product candidates.
If we do not achieve our projected development goals in the time frames we announce or expect, the development and potential commercialization of our product candidates may be delayed and our expenses may increase and, as a result, our business may be materially harmed and our stock price may decline.
From time to time, we announce the timing of the anticipated accomplishment of various scientific, clinical, regulatory, or other product development goals, which we sometimes refer to as milestones. These milestones may include the commencement or completion of scientific studies and clinical trials, such as the expected timing of our clinical trials in our target indications, anticipated data analysis, and the data results from our clinical trials, as well as the submission of regulatory filings. All of these milestones are and will be based on numerous assumptions. The actual timing of these milestones can vary dramatically compared to our estimates, in some cases for reasons beyond our control. If we do not meet these milestones or the timing of the milestones as publicly announced, the development and potential commercialization of our product candidates may be delayed or never achieved and, as a result, our business may be materially harmed and our stock price may decline. Additionally, delays relative to our projected timelines are likely to cause overall expenses to increase, which may require us to raise additional capital sooner than expected and on terms less than desirable, and prior to achieving targeted development milestones.
39
Any drug delivery device that we may use to deliver our product candidates may have its own regulatory, development, supply and other risks.
We are delivering and expect to continue to deliver, our product candidates via a drug delivery device, such as pre-filled syringe, an injector, or other delivery system. We currently expect to utilize drug delivery devices authorized for marketing under clearances of approvals held by third parties. Where approval of a drug product and device is sought under a single application, the increased complexity of the review process may delay approval. Our product candidates may not be approved or may be substantially delayed in receiving approval if the devices that we choose to develop do not gain and/or maintain their own regulatory approvals or clearances. In addition, some drug delivery devices are provided by single-source third-party companies. We may be dependent on the sustained cooperation and effort of those third-party companies both to supply the devices and, in some cases, to conduct the studies required for approval or other regulatory clearance of the devices. Even if approval is obtained for our products, we may also be dependent on those third-party companies continuing to maintain such approvals or clearances, if required, for their drug delivery devices once they have been received. Moreover, there may be unforeseen technical complications related to the development activities required to bring such a product to market, including primary container compatibility and/or dose volume requirements. Failure of third-party companies to supply the devices on time and in accordance with the agreed-upon specifications, to successfully complete studies on the devices in a timely manner, or to obtain or maintain required approvals or clearances of the devices could result in increased development costs, delays in or failure to obtain regulatory approval and delays in product candidates reaching patients.
Our approach to the discovery and development of our lead programs is unproven, and we may not be successful in our efforts to build a pipeline of programs with commercial value.
We have worked with Paragon to leverage clinically validated mechanisms of action and incorporate advanced antibody engineering to optimize half-life and other properties designed to overcome limitations of existing therapies. We have entered into antibody discovery and option agreements (the “Option Agreements”) with Paragon Therapeutics, Inc. (“Paragon”) and Paruka Holding LLC to facilitate the discovery and development of certain research programs with respect to which we have signed a license agreement with Paragon. Our two most advanced programs, ORKA-001 and ORKA-002, are licensed from Paragon and are purposefully designed to improve upon existing product candidates and products while maintaining the same, well-established mechanisms of action. However, the scientific research that forms the basis of our efforts to develop programs using half-life extension technologies is ongoing and may not result in viable programs. There is limited clinical data available on product candidates utilizing half-life extension technologies, especially in I&I indications, demonstrating whether they are safe or effective for long-term treatment in humans. The long-term safety and efficacy of these technologies and the extended half-lives and exposure profiles of our programs compared to currently approved products are unknown.
We may ultimately discover that utilizing half-life extension technologies for our specific targets and indications and any programs resulting therefrom does not possess certain properties required for therapeutic effectiveness. In addition, programs using half-life extension technologies may demonstrate different chemical and pharmacological properties in human participants than they do in laboratory studies or preclinical studies, including the inability to demonstrate the same chemical and pharmacological properties in humans or the potential interaction with human biological systems in unforeseen, ineffective, or harmful ways.
If the products resulting from the research programs with respect to which we have signed license agreements with Paragon prove to be ineffective, unsafe or commercially unviable, such programs would have little, if any, value, which would have a material and adverse effect on our business, financial condition, results of operations, and prospects.
In addition, we may in the future seek to discover and develop programs that are based on novel targets and in the technologies that are unproven. If our discovery activities fail to identify novel targets or technologies for drug discovery, or such targets prove to be unsuitable for treating human disease, we may not be able to develop viable additional programs.
40
Preclinical and clinical development involves a lengthy and expensive process that is subject to delays and uncertain outcomes and results of earlier studies and trials may not be predictive of future clinical trial results. Further, if our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our product candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such product candidate.
We do not know whether any clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market any of our product candidates. Clinical testing can take many years to complete, and its outcome is inherently uncertain. Our clinical trials may not be conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials and results in one indication may not be predictive of results to be expected for the same product candidate in another indication. We plan to use the data from our current trials of our ORKA-001 and ORKA-002 programs to support further trials in PsO, HS, and potentially other I&I indications. However, differences between early-stage clinical trials and later-stage clinical trials, including differences in trial design, among other things, make it difficult to extrapolate the results of earlier clinical trials to later clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unfavorable safety profiles, notwithstanding promising results in earlier trials. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of such product candidates. In addition, we rely on clinical trial site staff to measure psoriasis area severity index scores (PASI scores) and participants to provide feedback on measures such as measures of quality of life, which may involve subjective interpretation and variability, although training and standardized measurements will be provided to individuals in order to minimize subjectivity. Moreover, these measures can be influenced by factors outside of our control, and can vary widely within a clinical trial.
We cannot be sure that the FDA, or comparable foreign regulatory authority, as applicable, will agree with our clinical development plan. We cannot assure that the submission of an Investigational New Drug (IND) application, clinical trial application, or similar application will result in the FDA or comparable foreign regulatory authorities, as applicable, allowing clinical trials to begin in a timely manner, if at all. If the FDA and/or comparable foreign regulatory authority requires us to materially modify our proposed trial designs, conduct additional trials or enroll additional participants, our development timelines may be delayed. Moreover, even if these trials begin, issues may arise that could suspend or terminate such clinical trials, including but not limited to delays or difficulties recruiting trial patients, delays or difficulties obtaining required IRB or ethics committee approval at each clinical trial site, failure by third parties or us to adhere to clinical trial protocols or failure to perform in accordance with current Good Clinical Practice or applicable regulatory requirements, or delays in reaching a consensus with regulatory authorities on trial design or implementation of a clinical trial, or our third party vendors not satisfying their obligations to us.
We could also encounter delays if a clinical trial is required to be materially modified or suspended or terminated by us, the IRBs, by a Data Safety Monitoring Board, if any, or by the FDA or comparable foreign regulatory authorities. Such authorities may suspend, put on clinical hold, or terminate a clinical trial due to a number of factors, including not aligning with or supporting our clinical trial designs or our failure to conduct the clinical trial in accordance with regulatory requirements or our clinical trial protocols, inspection of the clinical trial operations or trial site by the FDA or comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. 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, if the results of these trials are not positive or are only moderately positive, or if there are safety concerns, our business and results of operations may be adversely affected and we may need to adjust or abandon our business plans and we may incur significant additional costs.
Our clinical development activities could be delayed or otherwise adversely affected if we encounter difficulties enrolling and maintaining participants in our current and future clinical trials. We depend on the successful completion of clinical trials for our product candidates.
Our inability to enroll and maintain a sufficient number of participants who remain in a trial until conclusion would result in significant delays in completing clinical trials and increased development costs or may require us to abandon one or more clinical trials altogether. The enrollment of participants in current or future trials for any of our programs will depend on many factors, including if participants choose to enroll in our clinical trials, rather than using approved products, or if our competitors have ongoing clinical trials for programs that are under development for the same indications as our programs and participants instead enroll in such clinical trials. Even if we are able to enroll a sufficient number of participants for our clinical trials, we may have difficulty maintaining participants in such clinical trials.
41
Preliminary, “topline”, or interim data from our clinical trials may change and are subject to audit and verification procedures, and should be viewed with caution until the final data are available. Our interpretation of such data is based on assumptions that may evolve as additional data become available, which could result in changes to conclusions regarding the safety, efficacy, timing, or likelihood of success of our clinical development programs.
From time to time, we may publicly disclose preliminary or topline data from our preclinical studies and clinical trials that are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data. We may also make assumptions, estimations, calculations, and conclusions as part of our analyses of these data without the opportunity to fully and carefully evaluate complete data. As a result, the preliminary or topline results that we report may differ from future results of the same studies and our conclusions may change or be qualified as additional data are received, fully evaluated, and subjected to audit and verification procedures.
We may also publicly disclose interim data from our preclinical studies and clinical trials. Such interim data are inherently preliminary and subject to the risk that one or more of the clinical outcomes may change as participant enrollment continues, additional data become available, as participants from our clinical trials pursue other treatments, or further analyses are conducted. In addition, third parties, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions, or analyses or may interpret or weigh the importance of data differently, which could impact the perceived value of the particular product candidate, the approvability or commercialization of the particular product candidate, and our company and our business in general. In addition, others may not agree with what we determine is material or otherwise appropriate information to include in our public disclosure of a particular preclinical study or clinical trial.
If the preliminary, topline, or interim data that we report differ from actual results, or if final data or data from later stage clinical trials do not produce favorable results, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.
Our clinical trials may reveal significant adverse events, undesirable side effects, or patient intolerance not seen in our preclinical studies or earlier clinical trials, and may result in a safety profile that could halt clinical development, inhibit regulatory approval, or limit commercial potential or market acceptance of any of our product candidates. We do not know whether any clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market any of our product candidates.
Results of our clinical trials could reveal an unacceptable severity and prevalence of side effects or patient intolerance, adverse events, or unexpected characteristics, and any of these occurrences could harm our business, financial condition, results of operations and prospects significantly. If significant adverse events or other side effects are observed in any of our clinical trials, we may have difficulty recruiting participants to such trials, participants may drop out of the trials, or we may have to suspend, materially modify or abandon the trials or our development efforts of one or more programs altogether. We, the FDA or other applicable regulatory authorities, or an IRB, may suspend or require the material modification of any clinical trials of any program or require that we repeat or conduct additional clinical trials at any time for various reasons, including safety and health risks or exposure to adverse side effects.
Even if side effects do not preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance of the approved product due to their tolerability versus other therapies. Potential side effects associated with our product candidates may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from our product candidates may not be normally encountered in the general patient population and by medical personnel. In addition, an extended half-life could prolong the duration of undesirable side effects, which could also affect our clinical trials or inhibit market acceptance.
In addition, even if we successfully advance our product candidates through clinical trials, such trials will only include a limited number of participants and limited duration of exposure to our product candidates. As a result, we cannot be assured that adverse effects of our product candidates will not be uncovered when a significantly larger number of participants are exposed to the product candidate after approval and potentially over an extended period of use. Further, any clinical trials may not be sufficient to determine the effect and safety consequences of using our product candidates over a multi-year period or longer.
If any of the foregoing events occur or if one or more of our product candidates prove to be unsafe, our pipeline could be affected, which would have a material adverse effect on our business, financial condition, results of operations, and prospects.
42
We may expend our limited resources to pursue a particular program and fail to capitalize on programs that may be more profitable or for which there is a greater likelihood of success.
We are initially focused on our most advanced programs, ORKA-001 and ORKA-002, and as a result, we may forgo or delay pursuit of opportunities with other programs that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may be in a position where we may have to relinquish valuable rights to that product candidate through collaboration, licensing or other arrangements in cases in which we would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. We may never receive approval to market and commercialize any product candidate.
Any approved products resulting from our programs may not achieve adequate market acceptance among clinicians, patients, healthcare third-party payors and others in the medical community necessary for commercial success and we may not generate any future revenue from the sale or licensing of such products.
Even if regulatory approval is obtained for a product candidate resulting from one of our current or future programs, it may not gain market acceptance among physicians, patients, third-party payors or others in the medical community. Market acceptance of our product candidates will depend on many factors, including factors that are not within our control. Market participants with influence over acceptance of new treatments, such as clinicians and third-party payors, may not adopt a biologic that incorporates half-life extension for our targeted indications, and we may not be able to convince the medical community and third-party payors to accept and use, or to provide favorable reimbursement for, any programs developed by us or our existing or future collaborators. Moreover, an extended half-life may make it more difficult for patients to change treatments and there may be a perception that half-life extension could exacerbate side effects, each of which may adversely affect our ability to gain market acceptance. Further, we may not generate or derive sufficient revenue from a product candidate and may not become or remain profitable if such product candidate is approved, but does not achieve an adequate level of acceptance.
Certain of our programs may compete with our other programs, which could negatively impact our business and reduce our future revenue.
We are developing product candidates for PsO, HS, and may in the future develop our programs for other I&I indications. Each such program targets a different mechanism of action. However, developing multiple programs for a single indication may negatively impact our business if the programs compete with each other. For example, concurrent clinical trials across multiple programs may compete for the enrollment of participants. In addition, the approval of multiple product candidates for the same indication could intensify market competition and limit our future revenues.
We are conducting, and may conduct in the future, clinical trials for programs at sites outside the United States, subjecting us to additional risks that may delay or adversely affect our product development timelines.
We are currently conducting clinical trials outside the United States and may continue to do so in the future. Conducting clinical trials outside the United States may expose us to additional operational and regulatory risks, including differing regulatory standards and review timelines and increased complexity in ensuring compliance with applicable laws and data protection requirements. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of this data is subject to conditions imposed by the FDA. If the FDA does not accept the data from any trial that we conduct outside the United States, it would likely result in the need for additional trials, which would be costly and time-consuming and would delay or permanently halt our development of the applicable product candidates. Even if the FDA accepted such data, it could impose additional conditions, such as requiring us to modify our planned clinical trials to receive clearance to initiate such trials in the United States or to continue such trials once initiated.
Further, conducting clinical trials outside of the United States presents additional risks that may delay completion of our clinical trials. These risks include requirements for local ethics approvals, challenges in monitoring trial conduct and data integrity across jurisdictions, including the potential failure of investigators or enrolled participants in foreign countries to adhere to clinical protocol that could restrict or limit our ability to conduct our clinical trials, the administrative burdens of conducting clinical trials under multiple sets of foreign regulations, potential restrictions, such as local privacy restrictions, on data generated from the clinical trial, and diminished protection of intellectual property in some countries. Operations in foreign jurisdictions are subject to additional risks, including dependence on third party manufacturers or suppliers outside of the United States, as well as political and economic risks relevant to foreign countries.
43
Risks Related to Government and Regulatory Matters
The regulatory approval processes of the FDA and other comparable foreign regulatory authorities are lengthy, time-consuming and unpredictable. We may not be able to commercialize, or may be delayed in commercializing, our product candidates, and our ability to generate revenue may be materially impaired if we are not able to obtain, or if there are delays in obtaining, required regulatory approvals for our product candidates.
The lengthy regulatory approval process as well as the unpredictability of clinical trial results may result in our failing to obtain or be delayed in obtaining approval to market our product candidates, which would significantly harm our business, results of operations and prospects. Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical studies and clinical trials that our product candidates are both safe and effective for each targeted indication. In addition, securing regulatory approval also requires the submission of information about the drug manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Of the large number of drugs in development, only a small percentage successfully complete the FDA or foreign regulatory approval processes and are commercialized. Approval may never be obtained and the approval process can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. While there are several approved products and product candidates in later stages of development for the treatment of PsO and for the treatment of HS, our programs incorporate advanced antibody engineering to optimize the half-life and formulation of antibodies, and to date, no such antibody has been approved by the FDA for the treatment of PsO or for HS.
The FDA and comparable foreign regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical, or other data. Our product candidates could be delayed in receiving, or fail to receive, regulatory approval for many reasons, including: the failure to demonstrate that a product candidate’s benefits outweigh safety risks; regulatory authorities may disagree with our interpretation of clinical data or the data collected may not be acceptable or sufficient to support submission; or the results may not meet the level of statistical significance required for approval by the relevant regulatory authorities or otherwise considered insufficient by the FDA or comparable foreign regulatory authorities. Regulatory authorities may require the addition of labeling statements, such as a black box warning or other warnings or contraindications that could diminish the usage of the product or otherwise limit the commercial success of the affected product.
Moreover, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, including failing to approve the most commercially promising indications, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals for our product candidates, we will not be able to commercialize, or will be delayed in commercializing, our product candidates and our ability to generate revenue may be materially impaired.
We may not be able to meet requirements for the chemistry, manufacturing, and control of our programs.
In order to receive approval of our products by the FDA and comparable foreign regulatory authorities, we must show that we and our CMO partners are able to characterize, control and manufacture our drug products safely and in accordance with regulatory requirements. This includes, among other things, manufacturing the active ingredient, developing an acceptable formulation, manufacturing the drug product, performing tests to adequately characterize the formulated product, documenting a repeatable manufacturing process in larger quantities as we move forward in our development programs, and demonstrating that our drug products meet stability requirements. As noted above, we may deliver our product candidates via a drug delivery device, which also requires us to meet certain chemistry, manufacturing and control requirements set forth by the FDA and other foreign regulatory authorities. Meeting these chemistry, manufacturing and control requirements is a complex task that requires specialized expertise. If we are not able to meet the chemistry, manufacturing, and control requirements, we may not be successful in our clinical trials or getting our product candidates approved by regulatory authorities.
Our product candidates for which we intend to seek approval as biologics may face competition sooner than anticipated.
The Patient Protection and Affordable Care Act, as amended by the Healthcare and Education Reconciliation Act (the “ACA”), includes a subtitle called the Biologics Price Competition and Innovation Act (the “BPCIA”), which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a highly similar or “biosimilar” product may not be submitted to the FDA until four years following the date that the reference product was first approved by the FDA. In addition, the approval 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 approved. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity, and potency of their product.
44
We believe that any of our product candidates approved as biologics 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 competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once approved, will be substituted for any reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.
Even if our product candidates receive regulatory approval, we will remain subject to extensive ongoing regulatory obligations and continued regulatory review, which could result in restrictions on the use of the products, significant additional expenses, and penalties if we fail to comply with regulatory requirements or experience unanticipated issues with our product candidates.
If any of our product candidates receive regulatory approval, we will remain subject to ongoing regulatory requirements imposed by the FDA and comparable foreign authorities. These requirements may include post-approval safety and pharmacovigilance reporting, product labeling restrictions or warnings, risk management requirements such as a Risk Evaluation and Mitigation Strategy (“REMS”), post-marketing commitments or additional studies to further assess safety, efficacy, or real-world use, as well as compliance with applicable manufacturing and quality system regulations.
Regulatory authorities may also conduct periodic inspections of our manufacturing facilities or those of our third-party manufacturers and may take enforcement action if we or such third parties fail to comply with applicable regulatory requirements or if safety, quality, or manufacturing issues arise. Such actions could include labeling changes, restrictions on use or distribution, clinical holds, recalls or withdrawal of products, warning or untitled letters, fines, penalties, or other enforcement measures. Failure to comply with these ongoing obligations, or the emergence of unexpected safety or quality issues after commercialization, could result in significant additional costs, limit our ability to commercialize, and may materially harm our business.
Disruptions or changes at the FDA, the SEC and other government agencies and regulatory authorities could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.
The ability of the FDA to review regulatory filings and our ability to commence clinical trials can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, statutory, regulatory and policy changes, disruptions caused by government shutdowns and public health crises. There have been mass layoffs of federal government employees since the start of the Trump administration in January 2025, the full impact of which is unclear at this time. Average review times at the agency have fluctuated in recent years as a result. 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. Furthermore, the Trump administration has made and is expected to continue to make changes in the leadership of various U.S. federal regulatory agencies and changes to U.S. federal government policy that have led to, in some cases, legal challenges and uncertainty around the funding, functioning and policy priorities of the U.S. federal regulatory agencies, including the FDA.
Disruptions at the FDA and other agencies or comparable foreign regulatory authorities, may also slow the time necessary for the review and approval of applications for clinical trial or marketing authorization, which would adversely affect our business. For example, in recent years, the U.S. government has experienced shut downs and funding lapses, during which time certain regulatory agencies, such as the FDA and the SEC, furloughed critical employees and stopped critical activities. Additionally, action by the Trump administration to limit federal agency budgets or personnel may result in reductions to the FDA’s budget, employees, and operations, which may lead to slower response times and longer review periods, potentially affecting our ability to progress development of our product candidates or obtain regulatory approval for our product candidates. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
45
We are unable to predict the extent to which the Trump administration may impose or seek to impose leadership or policy changes at the FDA or changes to rules and policies impacting our business and operations. It is unclear how these executive actions or other potential actions by the federal government will impact the FDA or other regulatory authorities that oversee our business. Government proposals to reduce or eliminate budgetary deficits may include reduced allocations to the FDA and other related government agencies. These budgetary pressures may reduce the FDA’s ability to perform its responsibilities, which could result in delays in our clinical trial timelines. If a significant reduction in the FDA’s workforce occurs, the FDA’s budget is significantly reduced or a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions or take other actions critical to the development or manufacturing of our product candidates, which could have a material adverse effect on our business.
If a prolonged government shutdown occurs, or if global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
We may face difficulties from legislative or regulatory reform measures.
We may be faced with additional or changing regulatory and governmental regulations that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. For example, the Trump administration has discussed several changes to the reach and oversight of the FDA, which could affect its relationship with the pharmaceutical industry, transparency in decision making and ultimately the cost and availability of prescription drugs. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.
The price of pharmaceuticals has been a topic of considerable public discussion that could lead to price controls or other price-limiting strategies by third-party payors that have the effect of lowering payment and reimbursement rates for drugs or otherwise making the commercialization of pharmaceuticals less profitable. Many federal and state legislatures have considered, and adopted, healthcare policies intended to curb rising healthcare costs, such as the Inflation Reduction Act (“IRA”). These cost-containment measures may include, among other measures: requirements for pharmaceutical companies to negotiate prescription drug prices with government healthcare programs; controls on government-funded reimbursement for drugs; new or increased requirements to pay prescription drug rebates to government healthcare programs, including if drug prices increase at a higher rate than inflation; controls on healthcare providers; challenges to or limits on the pricing of drugs, including pricing controls or limits or prohibitions on reimbursement for specific products through other means; requirements to try less expensive products or generics before a more expensive branded product; and public funding for cost effectiveness research, which may be used by government and private third-party payors to make coverage and payment decisions. Political, economic and regulatory developments may further complicate developments in healthcare systems and pharmaceutical drug pricing. These developments could, for example, impact our potential licensing agreements as commercial and collaborative partners may also consider the impact of these pressures on their licensing strategies.
Any new laws or regulations that have the effect of imposing additional costs or regulatory burden on pharmaceutical manufacturers, or otherwise negatively affect the industry, could adversely affect our ability to successfully commercialize our product candidates. The implementation of any price controls, caps on prescription drugs or price transparency requirements could adversely affect our business, operating results and financial condition.
Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations and customers will be subject to applicable healthcare regulatory laws, including conflicts of interest rules, which could expose us to penalties.
Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations and customers may expose us to broadly applicable healthcare laws and regulations, including conflict of interest laws. These laws may constrain the business or financial arrangements and relationships through which we conduct our operations.
Principal investigators for our clinical trials may serve as scientific advisors or consultants to us or may be affiliated with our other service providers, including CROs or site management organizations, and from time to time may receive cash compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site or in the applicable trial may be questioned or jeopardized.
Ensuring that our internal operations and future business arrangements with third parties comply with applicable healthcare laws and regulations will involve costs and management attention. If our operations are found to be in violation of any of these laws or any other governmental laws and regulations that may apply to it, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from government-funded healthcare programs, integrity oversight, and reporting obligations to resolve allegations of non-compliance, disgorgement, individual imprisonment, contractual damages, reputational harm, diminished profits, and the curtailment or restructuring of our operations. Further, defending against any such actions can be costly and time-consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired.
46
Even if we are able to commercialize any product candidates, we may be subject to unfavorable pricing regulations and/or third-party coverage and reimbursement policies, and we may not be able to offer such product candidates at competitive prices, which could seriously harm our business.
We intend to seek approval to market our product candidates in the United States and in selected foreign jurisdictions, and we will be subject to rules and regulations in those jurisdictions where we obtain approval. Our ability to successfully commercialize any product candidates that we may develop will depend in part on the extent to which reimbursement for these product candidates and related treatments will be available from government health administration authorities, private health insurers, and other organizations. In some jurisdictions, government authorities and other third-party payors decide which medications they will pay for and establish reimbursement levels, and have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. These entities may create preferential access policies for a competitor’s product, including a branded or generic/biosimilar product, over our products in an attempt to reduce their costs, which may reduce our commercial opportunity. Additionally, if any of our product candidates are approved and we are found to have improperly promoted off-label uses of those product candidates, we may become subject to significant liability, which could materially adversely affect our business and financial condition.
We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and regulations. We can face criminal liability and other serious consequences for violations, which can harm our business.
We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the U.S. Physician Payments Sunshine Act, and other state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, contractors, and other collaborators from authorizing, promising, offering, or providing, directly or indirectly, improper payments or anything else of value to or from recipients in the public or private sector. We may engage third parties to sell our products outside the United States, to conduct clinical trials, and/or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors, and other collaborators, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences.
Governments outside the United States tend to impose strict price controls, which may adversely affect our revenue, if any.
In some countries, particularly member states of the EU (“EU Member States”), the pricing of prescription drugs is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after receipt of marketing approval for a therapeutic. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic, and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various EU Member States and parallel distribution, or arbitrage between low-priced and high-priced EU Member States, can further reduce prices. To obtain coverage and reimbursement or pricing approvals in some countries, we or current or future collaborators may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of our product candidates to other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If reimbursement of any product candidate approved for marketing is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business, financial condition, results of operations, or prospects could be materially and adversely affected. If the UK or EU Member States were to significantly alter their regulations affecting the pricing of prescription pharmaceuticals, we could face significant new costs.

Risks Related to Our Intellectual Property
Our ability to obtain, maintain, and protect our patents and other proprietary rights is uncertain, exposing us to the possible loss of competitive advantage.
We rely upon a combination of patents, trademarks, trade secret protection, confidentiality agreements, and the Option and License Agreements with Paragon to protect the intellectual property related to our programs and technologies and to prevent third parties from competing unfairly with it. Our success depends in large part on our ability to obtain and maintain patent protection for our programs and our product candidates and their uses, as well as our ability to operate without infringing on or violating the proprietary rights of others. We and Paragon have filed, and may continue to file, provisional and non-provisional patent applications directed to antibodies that target IL-23, including applications covering composition of matter, pharmaceutical formulations, and methods of use, including ORKA-001. In addition, we and Paragon have filed, and may continue to file, provisional and non-provisional patent applications directed to antibodies that target IL-17, including applications covering composition of matter, pharmaceutical formulations, and methods of use, including ORKA-002. However, we may not be able to protect our intellectual property rights throughout the world and the legal systems in certain countries may not favor enforcement or protection of patents, trade secrets, and other intellectual property. Filing, prosecuting and defending patents on programs worldwide is expensive and our intellectual property rights in some foreign jurisdictions can be less extensive than those in the United States; the reverse may also occur. As such, we may not have patents in all countries or all major markets and may not be able to obtain patents in all jurisdictions even if we apply for them. Our competitors may operate in countries where we do not have patent protection and can freely use our technologies and discoveries in such countries to the extent such technologies and discoveries are publicly known or disclosed in countries where we do have patent protection or pending patent applications.
Our pending and future patent applications may not result in patents being issued. Any issued patents may not afford sufficient protection of our programs or their intended uses against competitors, nor can there be any assurance that the patents issued will not be infringed, designed around, or invalidated by third parties, or will effectively prevent others from commercializing competitive technologies, products, or programs. Even if these patents are granted, they may be difficult to enforce. Further, any issued patents that we may license or own covering our programs could be narrowed or found invalid or unenforceable if challenged in court or before administrative bodies in the United States or abroad, including the United States Patent and Trademark Office (“USPTO”). Further, if we encounter delays in our clinical trials or delays in obtaining regulatory approval, the period of time during which we could market our product candidates under patent protection would be reduced. Thus, the patents that we may own and license may not afford us any meaningful competitive advantage.
In addition to seeking patents for some of our technology and programs, we may also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. Any disclosure, either intentional or unintentional, by our employees, the personnel of third parties with whom we share our facilities, or third-party consultants and vendors that we engage to perform research, clinical trials or manufacturing activities, or misappropriation by third parties (such as through a cybersecurity breach) of our trade secrets or proprietary information could enable competitors to duplicate or surpass our technological achievements, thus eroding our competitive position in our market. In order to protect our proprietary technology and processes, we rely in part on agreements, such as confidentiality agreements, with our vendors, collaborators, employees, consultants, outside scientific collaborators and sponsored researchers and other advisors. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. We may need to share our proprietary information, including trade secrets, with future business partners, collaborators, contractors and others located in countries at heightened risk of theft of trade secrets, including through direct intrusion by private parties or state actors and those affiliated with or controlled by state actors. In addition, while we undertake efforts to protect our trade secrets and other confidential information from disclosure, others may independently discover trade secrets and proprietary information, and in such cases, we may not be able to assert any trade secret rights against such party. Enforcing a claim that a party illegally obtained and is using our trade secrets is challenging and the outcome is unpredictable. In addition, courts outside of the U.S. may be less willing to protect trade secrets. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.
Lastly, if our trademarks and trade names are not registered or adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.
48
We may not be successful in obtaining or maintaining necessary rights to our programs through acquisitions and in-licenses.
Because our development programs currently do and may in the future 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. It is possible that we may be unable to obtain licenses at a reasonable cost or on reasonable terms, if at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We may be unable to acquire or in-license any compositions, methods of use, processes or other intellectual property rights from third parties that we identify as necessary for our programs. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of 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 our investment or at all. If we are unable to successfully obtain rights to required third-party intellectual property or maintain the existing intellectual property rights we do obtain, we may have to abandon the development of the relevant program, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.
While we plan to obtain the right to control patent prosecution, maintenance, and enforcement of the patents relating to our programs, there may be times when the filing and prosecution activities for patents and patent applications relating to our programs are controlled by our current and future licensors or collaboration partners. If any of our current and future licensors or collaboration partners fail to prosecute, maintain, and enforce such patents and patent applications in a manner consistent with the best interests of our business, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using, and selling competing products. In addition, even where we have the right to control prosecution of patents and patent applications we have licensed to and from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensees, our future licensors, and our counsel that took place prior to the date upon which we assumed control over patent prosecution. Moreover, if other third parties have ownership rights to our future in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technology.
Failure to obtain licenses at a reasonable cost or on reasonable terms may require us to expend significant time and resources to redesign our technology, programs, or the methods for manufacturing them or to develop or license replacement technology, 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. This could have a material adverse effect on our competitive position, business, financial condition, results of operations, and prospects.
Disputes may arise between us and our future licensors regarding intellectual property subject to a license agreement, including without limitation: the scope of rights granted under the license agreement and other interpretation-related issues; whether and the extent to which our technology and processes may infringe on intellectual property of the licensor that is not subject to the licensing agreement; our right to sublicense patents and other rights to third parties; our right to transfer or assign the license; the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our future licensors and us and our partners; and the priority of invention of patented technology.
We may be subject to patent infringement claims or may need to file claims to protect our intellectual property, which could result in substantial costs and liability and prevent us from commercializing our potential products.
Because the intellectual property landscape in the biopharmaceutical industry is rapidly evolving and interdisciplinary, it is difficult to conclusively assess our freedom to operate and guarantee that we can operate without infringing on or violating third-party rights. Third-party patent rights, if found to be valid and enforceable, could be alleged to render one or more of our product candidates infringing. If a third party successfully brings a claim against us, we may be required to pay substantial damages, be forced to abandon or delay the development of any affected product candidate, and/or seek a license from the patent holder. Any intellectual property claims brought against us, whether or not successful, may cause us to incur significant legal expenses and divert the attention of our management and key personnel from other business concerns. We cannot be certain that patents owned or licensed by us will not be challenged by others in litigation. Some of our competitors may be able to sustain the costs of complex intellectual property litigation more effectively than we can because they may have substantially greater resources. In addition, any litigation could have a material adverse effect on our business and operations, including our ability to raise funds.
49
Competitors may infringe or otherwise violate our patents, trademarks, copyrights, or other intellectual property. To counter infringement or other violations, we may be required to file claims, which can be expensive and time-consuming, and any such claims could provoke these parties to assert counterclaims against us. In addition, in a patent infringement proceeding, a court or administrative body may decide that one or more of the patents we assert is invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to prevent the other party from using the technology at issue on the grounds that our patents do not cover the technology. Similarly, if we assert trademark (“marks”) infringement claims, a court or administrative body 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 such a case, we could ultimately be forced to cease use of such marks. In any intellectual property litigation, even if we are successful, any award of monetary damages or other remedy we receive may not be commercially valuable.
Further, we may be required to protect our patents through procedures created to attack the validity of a patent at the USPTO. An adverse determination in any such submission or proceeding could reduce the scope of, affect the enforceability of, or invalidate, our patent rights, which could adversely affect our competitive position. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. 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, if our programs are found to infringe the intellectual property rights of third parties, these third parties may assert infringement claims against our future licensees and other parties with whom we have business relationships and we may be required to indemnify those parties for any damages they suffer as a result of these claims, which may require us to initiate or defend protracted and costly litigation on behalf of licensees and other parties regardless of the merits of such claims. If any of these claims succeed, we may be forced to pay damages on behalf of those parties or may be required to obtain licenses for the products they use.
Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other legal proceedings relating to our intellectual property rights, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings.
Changes to patent laws in the U.S. and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.
Changes in either the patent laws or interpretation of patent laws in the U.S. and foreign jurisdictions could increase the uncertainties and costs surrounding the prosecution of our owned and in-licensed patent applications and the maintenance, enforcement or defense of our owned and in-licensed issued patents. Additionally, there have been proposals for additional changes to the patent laws of the U.S. and other countries that, if adopted, could impact our ability to enforce our proprietary technology. This combination of events has created uncertainty with respect to the validity and enforceability of patents once obtained. Depending on future actions by the U.S. Congress, the federal courts, the USPTO, and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our patent rights and our ability to protect, defend, and enforce our patent rights in the future. In addition, geopolitical instability could increase the uncertainties and costs surrounding the prosecution or maintenance of patent applications and the maintenance, enforcement, or defense of issued patents.
The patent positions of companies in the development and commercialization of biologics and pharmaceuticals are particularly uncertain. U.S. Supreme Court and U.S. Court of Appeals for the Federal Circuit rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations, including in the antibody arts. For example, the U.S. Supreme Court in Amgen, Inc. v. Sanofi (Amgen) stated that if patent claims are directed to an entire class of compositions of matter, then the patent specification must enable a person skilled in the art to make and use the entire class of compositions. This decision makes it unlikely that we will be granted U.S. patents with composition of matter claims directed to antibodies functionally defined by their ability to bind a particular antigen. Even if we are granted claims directed to functionally defined antibodies, it is possible that a third party may challenge our patents, when issued, relying on the reasoning in Amgen or other recent precedential court decisions.
50
In addition, a European Unified Patent Court (“UPC”) entered into force on June 1, 2023. The UPC is a common patent court that hears patent infringement and revocation proceedings effective for EU Member States. This could enable third parties to seek revocation of a European patent in a single proceeding at the UPC rather than through multiple proceedings in each of the jurisdictions in which the European patent is validated.
Although we do not currently own any European patents or applications, if we obtain such patents and applications in the future, any such revocation and loss of patent protection could have a material adverse impact on our business and our ability to commercialize or license our technology and products. Moreover, the controlling laws and regulations of the UPC will develop over time, and may adversely affect our ability to enforce or defend the validity of any European patents we may obtain. We may decide to opt out from the UPC any future European patent applications that we may file and any patents we may obtain. If certain formalities and requirements are not met, however, such European patents and patent applications could be challenged for non-compliance and brought under the jurisdiction of the UPC. We cannot be certain that future European patents and patent applications will avoid falling under the jurisdiction of the UPC, if we decide to opt out of the UPC.
Obtaining and maintaining patent protection depends on compliance with various procedural, document submissions, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
Periodic maintenance fees, renewal fees, annuities fees, and various other governmental fees on patents and/or patent applications are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent and/or patent application. The USPTO and various foreign governmental patent agencies also 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. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees, and failure to properly legalize and submit formal documents. If we fail to maintain the patents and patent applications covering our programs, our competitive position would be adversely affected.
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.
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 U.S. and abroad that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction. 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. For example, we may incorrectly determine that our products 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 U.S. or abroad that we consider relevant may be incorrect. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our products.
In addition, because some patent applications in the U.S. may be maintained in secrecy until the patents are issued, and because patent applications in the U.S. and many foreign jurisdictions are typically not published until 18 months after filing, and publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications, or that we were the first to invent the technology. Our competitors may have filed, and may in the future file, patent applications covering products or technology similar to ours. Any such patent application may have priority over our patent applications or patents, which could require us to obtain rights to issued patents covering such technologies.
51
We may become subject to claims challenging the inventorship or ownership of our patents and other intellectual property.
We may be subject to claims that former employees, collaborators, or other third parties have an interest in our patents or other intellectual property as an inventor or co-inventor. The failure to name the proper inventors on a patent application can impact the validity of the patents issuing thereon. 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 programs, 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. 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 an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.
Patent terms may be inadequate to protect the competitive position of our product candidates for an adequate amount of time.
Patents have a limited lifespan. In the U.S., if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is time limited. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products, including generics or biosimilars. Given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.
Our technology licensed from various third parties may be subject to retained rights.
Our future licensors may retain certain rights under the relevant 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 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.
In addition, our future licensors may rely on third-party consultants or collaborators or on funds from third parties, such as the U.S. government, such that our licensors would not be the sole and exclusive owners of any patents we in-license. If other third parties have ownership rights or other rights to our in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technology. This could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.
Risks Related to Our Reliance on Third Parties
We currently rely on licensing arrangements for a substantial portion of our product portfolio, including with Paragon for ORKA-001 and ORKA-002. If we are unable to maintain collaborations or licensing arrangements, or if our collaborations or licensing arrangements are not successful, our business could be negatively impacted.
Collaborations or licensing arrangements that we enter into may not be successful, and any success will depend heavily on the efforts and activities of such collaborators or licensors. If any of our current or future collaborators or licensors experience delays in performance of, or fails to perform, their obligations under their agreement with us, disagrees with our interpretation of the terms of such agreement or terminates their agreement with us, our development timeline could be adversely affected. We currently rely on our licensing agreements with Paragon for a substantial portion of our product portfolio, including for ORKA-001 and ORKA-002. If we fail to comply with any of the obligations under our collaborations or license agreements, including payment terms and diligence terms, our collaborators or licensors may have the right to terminate such agreements, in which event we may lose intellectual property rights and may not be able to develop, manufacture, market, or sell the products covered by our agreements or may face other penalties under our agreements. Our collaborators and licensors may also fail to properly maintain or defend the intellectual property we have licensed from them, if required by our agreement with them, or even infringe upon, our intellectual property rights, leading to the potential invalidation of our intellectual property or subjecting us to litigation or arbitration, any of which would be time-consuming and expensive and could harm our ability to commercialize our product candidates. In addition, collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our programs and products if the collaborators believe that the competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours.
52
As part of our strategy, we plan to evaluate additional opportunities to enhance our capabilities and expand our development pipeline or provide development or commercialization capabilities that complement ours. We may not realize the benefits of such collaborations, partnerships, or licensing arrangements. Any of these relationships 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.
We may face significant competition in attracting appropriate collaborators, and more established companies may also be pursuing strategies to license or acquire third-party intellectual property rights that we consider attractive. These 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 upon, among other things, 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. Collaborations are complex and time-consuming to negotiate, document, and execute. In addition, consolidation among large pharmaceutical and biotechnology companies has reduced the number of potential future collaborators. We may not be able to negotiate collaborations on a timely basis, 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.
We currently rely, and plan to rely in the future, on third parties to conduct and support our preclinical studies and clinical trials. If these third parties do not properly and successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval of or commercialize our product candidates.
We have utilized and plan to continue to utilize and depend upon independent investigators and collaborators, such as institutions, CROs, contract testing labs, CMOs and strategic partners, to supply, conduct, and support our preclinical studies and clinical trials pursuant to agreements with us. We will rely heavily on these third parties over the course of our preclinical studies and clinical trials, and we control only certain aspects of their activities. As a result, we will have less direct control over the conduct, timing, and completion of these preclinical studies and clinical trials and the management of data developed through preclinical studies and clinical trials than would be the case if we were relying entirely upon our own staff. Nevertheless, we are responsible for ensuring that each of our studies and trials is conducted in accordance with the applicable protocol, legal, regulatory, and scientific standards, and our reliance on these third parties does not relieve us of our regulatory responsibilities. We and our third-party contractors and CROs are required to comply with GCP regulations, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for all of our programs in clinical development. If we or any of these third parties fail to comply with applicable GCP regulations, 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 or refuse to approve our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP regulations. Moreover, our business may be implicated if any of these third parties violate federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.
Although we have remedies available to us under our agreements, any third parties conducting our preclinical studies or clinical trials will not be our employees and we cannot control whether they devote sufficient time and resources to our programs. These third parties may have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other product development activities, which could negatively affect their performance on our behalf and the timing thereof and could lead to products that compete directly or indirectly with our product candidates. If these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to complete development of, obtain regulatory approval of or successfully commercialize our product candidates.
53
We rely on the use of manufacturing suites in third-party facilities or on third parties to manufacture our product candidates, and we may rely on third parties to produce and process our products, if approved. Our business could be adversely affected if we are unable to use third-party manufacturing suites or if the third-party manufacturers encounter difficulties in production.
We do not currently own any facility that may be used as our clinical or commercial manufacturing and processing facility and must currently rely on CMOs to manufacture our product candidates. We have not yet caused any product candidates to be manufactured on a commercial scale and may not be able to do so for any of our product candidates, if approved. We currently have a sole source relationship for our supply of the ORKA-001 and ORKA-002 programs. If there should be any disruption in such supply arrangement, including any adverse events affecting our sole supplier, it could have a negative effect on the clinical development of our programs and other operations while we work to identify and qualify an alternate supply source. We do not control the manufacturing process of, and are completely dependent on, our contract manufacturing partners for compliance with cGMP requirements and any other regulatory requirements of the FDA or comparable foreign regulatory authorities for the manufacture of our product candidates. Beyond periodic audits, we have limited control over the ability of our CMOs to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any approval in the future, we may need to find alternative manufacturing facilities, which would require the incurrence of significant additional costs, delays, and materially adversely affect our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Similarly, our failure, or the failure of our CMOs, to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates or drugs and harm our business and results of operations.
Moreover, our CMOs may experience manufacturing difficulties due to resource constraints, supply chain issues, proposed or actual legislative changes or requirements, or as a result of labor disputes or unstable political environments. If any CMOs on which we will rely fail to manufacture quantities of our product candidates at quality levels necessary to meet regulatory requirements and at a scale sufficient to meet anticipated demand at a cost that allows us to achieve profitability, our business, financial condition, and prospects could be materially and adversely affected. In addition, our CMOs are responsible for transporting temperature-controlled materials that can be inadvertently degraded during transport due to several factors, rendering certain batches unsuitable for trial use for failure to meet, among others, our integrity and purity specifications. We and any of our CMOs may also face product seizure or detention or refusal to permit the import or export of products. Our business could be materially adversely affected by business disruptions to our third-party providers that could materially adversely affect our anticipated timelines, potential future revenue and financial condition, and increase our costs and expenses. Each of these risks could delay or prevent the completion of our preclinical studies and clinical trials or the approval of any of our product candidates by the FDA, result in higher costs, or adversely impact commercialization of our product candidates.
Foreign CMOs may be subject to U.S. legislation, including the BIOSECURE Act, trade restrictions, and other foreign regulatory requirements, which could increase costs, reduce the availability of materials, delay procurement or supply, or otherwise adversely affect our operations. We currently rely on foreign CROs and CMOs, including WuXi Biologics (Hong Kong) Limited and its affiliates (“WuXi Biologics”), and we expect to continue to rely on foreign CROs and CMOs in the future.
The BIOSECURE Act was enacted into U.S. law in December 2025 and restricts U.S. federal agencies, as well as recipients of certain federal funding, from procuring, using, or contracting for biotechnology equipment or services from entities designated as “biotechnology companies of concern”. The law contemplates a designation process to identify such biotechnology companies of concern, and the timing, scope, and implementation of the Act, including the criteria for designation and the application of any transition or grandfathering provisions, remain subject to ongoing rulemaking and agency interpretation.
WuXi Biologics has been identified in prior legislative proposals and public discourse as a potential biotechnology company of concern; however, it has not been automatically designated as such under the enacted statute. If WuXi Biologics or other third-party providers we rely on were to be designated as biotechnology companies of concern in the future, or if the BIOSECURE Act were otherwise interpreted or implemented in a manner that restricts our ability to use their services, we could be required to transition to alternative providers, experience supply disruptions or increased costs, or be limited in our ability to access U.S. federal government contracts, grants, or other funding opportunities, which could materially adversely affect our business, financial condition, or results of operations.
Furthermore, our operations and financial condition may be negatively impacted as a result of any delays or increased costs arising from the trade restrictions and other foreign regulatory requirements affecting such collaborators. In addition, while we have established relationships with CROs and CMOs outside of China, moving to those suppliers in the event of geopolitical instability affecting our collaborators in China could introduce delays into the development program. For example, in April 2025, the United States government imposed significant tariffs on imports from China and other countries and may impose more restrictions on goods, including biologically derived substances, manufactured in or imported from China or other countries, or impose other restrictions on companies’ ability to work with Chinese or other foreign counterparties. To the extent these or future tariffs are applicable to the material we import from China and other countries or if we are not able to secure supply of our product candidates as a result of applicable legislation, our business and financial condition could be adversely affected.
54
Risks Related to Employee Matters, Managing Growth and Other Risks Related to Our Business
In order to successfully implement our plans and strategies, we will need to grow the size of our organization and we may experience difficulties in managing this growth.
We expect to grow the size of our organization, including an increase in the number of our employees and the scope of our operations, particularly in the areas of preclinical and clinical drug development, technical operations, clinical operations, regulatory affairs and, potentially, sales and marketing. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial personnel and systems, expand our facilities, and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team working together 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.
We are highly dependent on our key personnel and anticipate hiring new key personnel. If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.
Our ability to pursue our growth strategy will be limited if we are unable to continue to attract and retain high quality personnel. We have been and will continue to be highly dependent on the research and development, clinical, and business development expertise of our executive officers, as well as the other principal members of our management, scientific, and clinical team. Any of our management team members may terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees.
Attracting and retaining qualified personnel will also be critical to our success, including with respect to any strategic transaction that we may pursue. The loss of our executive officers or other key employees could impede the achievement of our research, development, and commercialization objectives and seriously harm our ability to successfully 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, facilitate regulatory approval of, and commercialize product candidates. 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 pharmaceutical and biotechnology companies for similar personnel, as well as from universities and research institutions.
In addition, we rely on consultants and advisors to assist us in formulating our discovery and nonclinical and clinical 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.
We may be subject to claims that we have wrongfully hired an employee from a competitor or that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.
As is common in the biopharmaceutical industry, in addition to our employees, we engage the services of consultants and independent contractors to assist us in the development of our programs. Many of these consultants, independent contractors, and our employees, may have been previously employed at, or may have previously provided or may be currently providing consulting services to, other biotechnology or pharmaceutical companies including our competitors or potential competitors. Although we try to ensure that our employees, consultants, and independent contractors do not use the intellectual property, proprietary information, know-how, or trade secrets of others in their work for us, we may become subject to claims that we caused an individual to breach the terms of his or her non-competition or non-solicitation agreement, or that we or these individuals have, inadvertently or otherwise, used or disclosed the alleged trade secrets or other proprietary information of a former employer or competitor.
While we may litigate to defend ourselves against these claims, even if we are successful, litigation could result in substantial costs and could be a distraction to management. If our defenses to these claims fail, in addition to requiring us to pay monetary damages, a court could prohibit us from using technologies or features that are essential to our programs, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. Moreover, any such litigation or the threat thereof may adversely affect our reputation or our ability to form strategic alliances or sublicense our rights to collaborators, engage with scientific advisors or hire employees, consultants or independent contractors, each of which would have an adverse effect on our business, results of operations, and financial condition.
Our future growth may depend, in part, on our ability to operate in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.
Our future growth may depend, in part, on our ability to develop and commercialize our product candidates in foreign markets for which we may rely on collaboration with third parties. If we fail to comply with the regulatory requirements in foreign markets and receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed and our business will be adversely affected. Moreover, even if we obtain approval of our product candidates and ultimately commercialize our product candidates in foreign markets, we would be subject to the risks and uncertainties, including the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements, and reduced protection of intellectual property rights in some foreign countries.
55
Our employees, independent contractors, consultants, advisors, commercial collaborators, principal investigators, CROs, CMOs, suppliers, and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.
We are exposed to the risk that our employees, independent contractors, consultants, advisors, commercial collaborators, principal investigators, CROs, CMOs, suppliers, and vendors acting for or on our behalf may engage in misconduct or other improper activities. We have adopted a code of conduct and ethics, but it is not always possible to identify and deter misconduct by these 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 comply with these laws or regulations.
Our internal information technology systems, or those of any of our third-party service providers, or potential future collaborators, may fail or suffer security or data privacy breaches or other unauthorized or improper access to, use of, or destruction of our proprietary or confidential data, employee data or personal data, which could result in additional costs, loss of revenue, significant liabilities, harm to our brand and material disruption of our operations.
In the ordinary course of our business, we and the third parties upon which we rely collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, process) proprietary, confidential, and sensitive data, including personal data, intellectual property, trade secrets, and other sensitive data (collectively, sensitive information). If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences. While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. Further, cybersecurity breaches or other cybersecurity incidents may allow hackers access to our preclinical compounds, strategies, discoveries, trade secrets, and/or other confidential information. Additionally, sensitive data could be leaked, disclosed, or revealed as a result of or in connection with our employees’, personnel’s, vendors’ or partners’ use of generative AI technologies. Our ability to monitor third parties’ information security practices is limited, and these third parties may not have adequate security measures in place. We may be unable in the future to detect vulnerabilities in our information technology systems because such threats and techniques change frequently, are often sophisticated in nature, and may not be detected until after a security incident has occurred. Further, we may experience delays in developing and deploying remedial measures designed to address any such identified vulnerabilities. Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences. Moreover, while we may be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient or we may be unable to recover such award. Security incidents and attendant consequences may negatively impact our ability to grow and operate our business. The risk of a cybersecurity incident or other information technology disruption, particularly through cyber-attacks, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased.
To the extent that any disruption or security breach were to result in loss, destruction, unavailability, alteration or dissemination of, or damage to, our data (including clinical trial data) or applications, or for it to be believed or reported that any of these occurred, we could incur liability, including under laws and regulations governing the protection of protected health information and other personal data, and reputational damage and the development and commercialization of our product candidates could be delayed. Further, our insurance policies may not be adequate to compensate us for the potential losses arising from any such disruption in, or failure or security breach of, our systems or third-party systems where information important to our business operations or commercial development is stored.
Despite the implementation of security measures in an effort to protect systems that store our information, given their size and complexity and the increasing amounts of information maintained on our internal information technology systems and those of our third-party CROs, contractors, sites performing our clinical trials, third-party service providers and supply chain companies, and consultants, these systems are potentially vulnerable to breakdown or other damage or interruption from service interruptions, system malfunction, natural disasters, terrorism, war and telecommunication and electrical failures, as well as security breaches from inadvertent or intentional actions or from cyber-attacks by malicious third parties, or ransomware attacks, which, in each case, may compromise our system infrastructure or lead to the loss, destruction, alteration or dissemination of, or damage to, our data.
Our hybrid-remote workforce may create additional risks for our information technology systems and data because our employees work remotely and utilize network connections, computers, and devices working at home, while in transit and in public locations.
56
Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.
We are subject to stringent and changing laws, regulations and standards, and contractual obligations relating to privacy, data protection, and data security. The actual or perceived failure to comply with such obligations could lead to government enforcement actions (which could include civil or criminal penalties), fines and sanctions, private litigation and/or adverse publicity and could negatively affect our operating results and business.
We and third parties who we work with are or may become subject to numerous domestic and foreign laws, regulations, and standards relating to privacy, data protection, data transfer, and data security, the scope of which is changing, subject to differing applications and interpretations, and may be inconsistent among countries, or conflict with other rules. We are or may become subject to the terms of contractual obligations related to privacy, data protection and data security. Our obligations may also change or expand as our business grows. The actual or perceived failure by us or third parties related to us to comply with such laws, regulations and obligations could increase our compliance and operational costs, expose us to regulatory scrutiny, actions, fines and penalties, result in reputational harm, lead to a loss of customers, result in litigation and liability, and otherwise cause a material adverse effect on our business, financial condition, and results of operations.
If we fail to comply with environmental, health, and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
We are subject to numerous environmental, health, and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment, and disposal of hazardous materials and wastes. Our operations may involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. In addition, we may incur substantial costs in order to comply with current or future environmental, health, and safety laws and regulations. These current or future laws and regulations may impair our research, development, or commercialization efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties, or other sanctions.
We may be subject to adverse U.S. legislative or regulatory tax changes that could negatively impact our financial condition.
The rules dealing with U.S. federal, state, and local income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service and the U.S. Treasury Department. Changes to tax laws (which may have retroactive application) could adversely affect our stockholders or us. We continue to assess the impact of various tax reform proposals and modifications to existing tax treaties in all jurisdictions where we have operations or employees to determine the potential effect on our business and any assumptions we make about our future taxable income. We cannot predict whether any specific proposals will be enacted, the terms of any such proposals or what effect, if any, such proposals would have on our business if they were to be enacted. For example, the United States enacted the IRA, which implements, among other changes, a 1% excise tax on certain stock buybacks. In addition, beginning in 2022, the Tax Cuts and Jobs Act eliminated the previously available option to deduct research and development expenditures and requires taxpayers to amortize them generally over five years for research activities conducted in the United States and over 15 years for research activities conducted outside the United States. Such changes, among others, may adversely affect our effective tax rate, results of operation and general business condition.
We may acquire businesses or products, or form strategic alliances, in the future, and may not realize the benefits of such acquisitions.
We may acquire additional businesses or products, form strategic alliances, or create joint ventures with third parties that we believe will complement or augment our existing business. If we acquire businesses with promising markets or technologies, we may not be able to realize the benefit of acquiring such businesses if we are unable to successfully integrate them with our existing operations and company culture. We may encounter numerous difficulties in developing, manufacturing, and marketing any new product candidates or products resulting from a strategic alliance or acquisition that delay or prevent us from realizing their expected benefits or enhancing our business. There is no assurance that, following any such acquisition, we will achieve the synergies expected in order to justify the transaction, which could result in a material adverse effect on our business and prospects.
57
We maintain our cash at financial institutions, often in balances that exceed federally-insured limits. The failure of financial institutions could adversely affect our ability to pay our operational expenses or make other payments.
Our cash held in non-interest-bearing and interest-bearing accounts exceeds the Federal Deposit Insurance Corporation insurance limits. If such banking institutions were to fail, we could lose all or a portion of those amounts held in excess of such insurance limitations. In addition, even if account holders are ultimately made whole with respect to a future bank failure, account holders’ access to their accounts and assets held in their accounts may be substantially delayed. Any material loss that we may experience in the future or inability for a material time period to access our cash and cash equivalents could have an adverse effect on our ability to pay our operational expenses or make other payments, which could adversely affect our business.
General Risk Factors
Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business may not grow at similar rates, or at all.
Our market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Even if the markets in which we compete meet our size estimates and growth forecasts, our business may not grow at similar rates, or at all. Our growth is subject to many factors, including our success in implementing our business strategy, which is subject to many risks and uncertainties.
Our revenue will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval, the accepted price for the product, the ability to obtain coverage and reimbursement, and whether we own the commercial rights for that territory. If the number of our addressable patients is not as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect or the treatment population is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products, even if approved.
We may become exposed to costly and damaging product liability claims and our insurance may not cover all damages from such claims.
We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing, and use of pharmaceutical products. The use of a product candidate in clinical trials and the sale of any approved products in the future may expose us to liability claims. An individual or group of individuals may bring a liability claim against us if one of our product candidates causes, or merely appears to have caused, an injury, either at the clinical or commercial stage. Any claims against us, regardless of their merit, could be difficult and costly to defend and could materially and adversely affect our business. While we carry product liability insurance for our clinical trials, it is possible that any liabilities could exceed our insurance coverage or that in the future we may not be able to maintain insurance coverage at a reasonable cost or obtain insurance coverage that will be adequate to satisfy any liability that may arise. On occasion, large judgments have been awarded in class action or individual lawsuits. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could decrease our cash and our business operations could be impaired.
Litigation costs and the outcome of litigation could have a material adverse effect on our business.
From time to time, we may be subject to litigation claims through the ordinary course of our business operations regarding, but not limited to, employment matters, security of patient and employee personal information, contractual relations with collaborators, and intellectual property rights. Litigation to defend ourselves against claims by third parties, or to enforce any rights that we may have against third parties, may continue to be necessary, which could result in substantial costs and diversion of our resources, causing a material adverse effect on our business, financial condition, results of operations, or cash flows.
58
Our business could be adversely affected by economic downturns, inflation, fluctuation in interest rates, natural disasters, public health crises, political crises, geopolitical events or other macroeconomic conditions, which could have a material and adverse effect on our results of operations and financial condition.
The global economy, including credit and financial markets, has experienced and may experience in the future extreme volatility and disruptions, including, among other things, diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, supply chain shortages, new or increased tariffs, and other barriers to trade, especially in light of recent executive orders made by the Trump administration, trade and other international disputes, increases in inflation rates, fluctuation in interest rates, slower growth or recession, tighter credit, volatility in financial markets, high unemployment, labor availability constraints, public health crises, significant natural disasters, changes to fiscal and monetary policy, or government budget dynamics (particularly in the pharmaceutical and biotechnology areas), political and military conflict, and uncertainty about economic stability. Recently, the U.S. has announced tariffs on imports from most countries, including significant tariffs on imports from China. Historically, tariffs have led to increased trade and political tensions. In response to tariffs, other countries have implemented retaliatory tariffs on U.S. goods. Political tensions as a result of trade policies could reduce trade volume, investment, technological exchange, and other economic activities between major international economies, resulting in a material adverse effect on global economic conditions and the stability of global financial markets. There is substantial uncertainty about the duration of existing tariffs and whether additional tariffs may be imposed, modified or suspended. Fluctuation in interest rates, coupled with reduced government spending and volatility in financial markets, may increase economic uncertainty and affect consumer spending. Similarly, the ongoing military conflict between Russia and Ukraine and in the Middle East and rising tensions with China have created extreme volatility in the global capital markets and may have further global economic consequences, including disruptions of the global supply chain. Any such volatility and disruptions may adversely affect our business or the third parties on whom we rely. If the equity and credit markets deteriorate, including as a result of economic or political uncertainty, political unrest or war, it may make any necessary debt or equity financing more costly, more dilutive, or more difficult to obtain in a timely manner or on favorable terms, if at all. Increased inflation rates can adversely affect us by increasing our costs, including materials, operational, labor and employee benefit costs.
We may in the future experience disruptions as a result of such macroeconomic conditions, including delays or difficulties in initiating or expanding clinical trials and manufacturing sufficient quantities of materials. Any one or a combination of these events could have a material and adverse effect on our results of operations and financial condition.
Geopolitical events and global economic conditions may also affect the ability of the FDA and other regulatory authorities to perform routine functions. If such concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.
Risks Related to Owning Our Stock
The market price of our common stock has been, and may continue to be, volatile.
The market price of our common stock has been and is likely to be highly volatile and is subject to significant fluctuations. 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. For example, escalating trade tensions, elevated interest rates, and regulatory uncertainty have caused significant market volatility recently, and particularly in the biotechnology and biopharmaceutical industries. 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.
59
Furthermore, market volatility may lead to securities litigation or increased stockholder activism if we experience a market valuation that activists believe is not reflective of our 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, financial condition and cash flows. Class action securities litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability and reputation.
Some of the factors that may cause the market price of our common stock to fluctuate include:
| ● | Timing and results of clinical trials and preclinical studies of our product candidates, or those of our competitors or our existing or future collaborators; |
| ● | Failure to meet or exceed financial and development projections that we may provide to the public; |
| ● | Announcements of significant or potential equity or debt sales by us; |
| ● | Actions taken by regulatory agencies with respect to our product candidates, clinical studies, manufacturing process, or sales and marketing terms; |

Our certificate of incorporation and bylaws, as well as provisions under Delaware law, could make an acquisition of the company more difficult and may prevent attempts by our stockholders to replace or remove management.
Provisions in our certificate of incorporation and bylaws may discourage, delay, or prevent a merger, acquisition or other change in control of the company that stockholders may consider favorable, including transactions in which our common stockholders might otherwise receive a premium price for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions:
| ● | Establish a classified board of directors such that all members of the board are not elected at one time; |
| ● | Allow the authorized number of our directors to be changed only by resolution of our board of directors; |
| ● | Limit the manner in which stockholders can remove directors from the board; |
| ● | Establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on at stockholder meetings; |
| ● | Require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written consent; |
| ● | Limit who may call a special meeting of stockholders; |
| ● | Authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors; and |
| ● | Require the approval of the holders of at least 66 2/3% of the votes that all stockholders would be entitled to cast to amend or repeal certain provisions of our charter or bylaws. |
Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law (“DGCL”), which prohibits stockholders owning more than 15% of our outstanding voting stock from merging or combining with us. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirors to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders.
Our governing documents provide that, unless we consent in writing to the selection of an alternative forum, certain designated courts will be the sole and exclusive forum for certain legal actions between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.
Our governing documents provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware is the sole and exclusive forum for state law claims for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of or based on a breach of a fiduciary duty owed by any of our current or former directors, officers, or other employees or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, the certificate of incorporation or the bylaws, (iv) any action to interpret, apply, enforce or determine the validity of the certificate of incorporation or bylaws, or (v) 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, which for purposes of this risk factor refers to herein as the “Delaware Forum Provision”. Our governing documents further provide that, unless we consent in writing to an alternative forum, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, which for purposes of this risk factor refers to herein as the “Federal Forum Provision”. Neither the Delaware Forum Provision nor the Federal Forum Provision will apply to any causes of action arising under the Exchange Act. In addition, any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to the foregoing Delaware Forum Provision and Federal Forum Provision; provided, however, that stockholders cannot and will not be deemed to have waived our compliance with the U.S. federal securities laws and the rules and regulations thereunder.
61
The Delaware Forum Provision and the Federal Forum Provision may impose additional litigation costs on our stockholders in pursuing any such claims, particularly if such stockholders do not reside in or near the State of Delaware. Additionally, these forum selection clauses may limit our stockholders’ ability to bring a claim in a judicial 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.
Future sales of shares by existing stockholders, or the anticipation of such events, could cause our stock price to decline.
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 October 2025 we filed a registration statement on Form S-3 covering the resale of 39,425,806 shares of our common stock (including shares of common stock issuable upon the conversion of outstanding Series B Preferred Stock, or issuable upon the exercise of outstanding pre-funded warrants to purchase shares of common stock). The sale of these shares in the public market or the perception that holders of a large number of the securities intend to sell their securities could significantly reduce the price of our common stock. We cannot predict if and when the selling stockholders listed in the registration statement may sell such shares in the public markets. In addition, shares of our common stock that are subject to our outstanding options will become eligible for sale in the public market to the extent permitted by the provisions of various vesting agreements and Rules 144 and 701 under the Securities Act. Furthermore, in the future, we may issue additional shares of common stock or other equity or debt securities convertible into shares of common stock.
We do not anticipate that we will pay any cash dividends in the foreseeable future.
We do not anticipate that we will pay any cash dividends in the foreseeable future. The current expectation is that we will retain our future earnings, if any, to fund the development and growth of our business. As a result, capital appreciation, if any, of our common stock will be your sole source of gain, if any, for the foreseeable future.
Our executive officers, directors, and principal stockholders have the ability to control or significantly influence all matters submitted to our stockholders for approval.
Our executive officers, directors, and principal stockholders beneficially own a significant percentage of our outstanding common stock. As a result, if these stockholders were to choose to act together, 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 stockholders, if they choose to act together, would 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 our acquisition on terms that other stockholders may desire.
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 to not provide research coverage of our common stock, and such lack of research coverage may adversely affect the market price of our common stock. If 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.
