Notes to Unaudited Condensed Consolidated Financial Statements
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Organization
Inhibrx Biosciences, Inc., or the Company, or Inhibrx, is a clinical-stage biopharmaceutical company focused on developing a broad pipeline of novel biologic therapeutic candidates. The Company combines target biology with protein engineering, technologies, and research and development to design therapeutic candidates. The Company’s current pipeline is focused on oncology.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC, related to an interim report on Form 10-Q. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All intercompany accounts and transactions have been eliminated in consolidation.
The unaudited interim condensed consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results for the periods presented. All such adjustments are of a normal and recurring nature. The operating results presented in these unaudited interim condensed consolidated financial statements are not necessarily indicative of the results that may be expected for any future periods.
Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the related notes thereto for the fiscal year ended December 31, 2025, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on March 19, 2026.
Liquidity
As of June 30, 2026, the Company had an accumulated deficit of $316.3 million and cash and cash equivalents of $133.3 million. From its inception and through June 30, 2026, the Company has devoted substantially all of its efforts to therapeutic drug discovery and development, conducting preclinical studies and clinical trials, enabling manufacturing activities in support of its therapeutic candidates, pre-commercialization activities, organizing and staffing the Company, establishing its intellectual property portfolio and raising capital to support and expand these activities.
The Company believes that its existing cash and cash equivalents will be sufficient to fund the Company’s operations for at least 12 months from the date these consolidated financial statements are issued. The Company plans to finance its future cash needs through equity offerings, debt financings or other capital sources, including potential collaborations, licenses, strategic transactions and other similar arrangements.
If the Company does raise additional capital through public or private equity or convertible debt offerings, the ownership interests of its existing stockholders will be diluted, and the terms of those securities may include liquidation or other preferences that adversely affect its stockholders’ rights. If the Company raises capital through additional debt financings, it may be subject to covenants limiting or restricting its ability to take specific actions, such as incurring additional debt or making certain capital expenditures. To the extent that the Company raises additional capital through strategic licensing, collaboration or other similar agreements, it may have to relinquish valuable rights to its therapeutic candidates, future revenue streams or research programs at an earlier stage of development or on less favorable terms than it would otherwise choose, or to grant licenses on terms that may not be favorable to the Company. There can be no assurance as to the availability or terms upon which such financing and capital might be available in the future. If the Company is unable to secure adequate additional funding, it will need to reevaluate its operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, delay, scale back or eliminate some or all of its development programs, or
8
relinquish rights to its technology on less favorable terms than it would otherwise choose. These actions could materially impact its business, financial condition, results of operations and prospects.
The rules and regulations of the SEC or any other regulatory agencies may restrict the Company’s ability to conduct certain types of financing activities, or may affect the timing of and amounts it can raise by undertaking such activities.
Use of Estimates
The preparation of these unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expense and the disclosure of contingent assets and liabilities in the Company’s financial statements and accompanying notes. The Company’s most significant estimates relate to accounting for development work and preclinical studies and clinical trials, determining the assumptions used in measuring stock-based compensation, the fair value of warrants, and the incremental borrowing rate estimated in relation to the Company’s operating lease. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. The Company’s actual results may differ from these estimates under different assumptions or conditions.
Cash and Cash Equivalents
Cash and cash equivalents are comprised of cash held in financial institutions including readily available checking, overnight sweep, and money market accounts.
Concentrations of Credit Risk
Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits by the Federal Deposit Insurance Corporation, or the FDIC, of up to $250,000. The Company’s cash management and investment policy limits investment instruments to investment-grade securities with the objective to preserve capital and to maintain liquidity until the funds can be used in operations. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash balances due to the financial condition of the depository institutions in which those deposits are held.
Fair Value Measurements
The Company determines the fair value measurements of applicable assets and liabilities based on a three-tier fair value hierarchy established by accounting guidance and prioritizes the inputs used in measuring fair value. These tiers include:
•Level 1 - Quoted prices in active markets for identical assets or liabilities.
•Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
9
Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type are presented in the following table (in thousands):
| Level 1 | Level 2 | Level 3 | Total | ||||||||||||||||||||
| June 30, 2026 | |||||||||||||||||||||||

| December 31, 2025 | |||||||||||||||||||||||
| Money market funds | $ | $ | $ | $ | |||||||||||||||||||
| Total assets measured at fair value | $ | $ | $ | $ | |||||||||||||||||||
The Company’s long-term outstanding debt is not measured at fair value on a reoccurring basis. As of June 30, 2026 and December 31, 2025, the Company’s long-term outstanding debt approximates fair value using Level 2 inputs.
Accrued Research and Development and Clinical Trial Costs
Income Taxes
Net Loss Per Share
Basic net loss per share is computed by dividing net loss by the weighted average number of common stock outstanding during the same period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common and common stock equivalents outstanding during the same period. The Company excludes common stock equivalents from the calculation of diluted net loss per share when the effect is anti-dilutive.
The weighted average number of shares of common stock used in the basic and diluted net income (loss) per common stock calculations includes the weighted-average pre-funded warrants outstanding during the period as they are exercisable at any time for nominal cash consideration.
In periods in which the Company has a net loss, basic loss per share and diluted loss per share are identical since the effect of potentially dilutive common shares is anti-dilutive and therefore excluded. Accordingly, for the three and six months ended June 30, 2026 and June 30, 2025, there is no difference in the number of shares used to calculate basic and diluted shares outstanding.

Segment Information
Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker, or CODM, in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one
The CODM assesses performance for the biologic therapeutic segment and decides how to allocate resources based on the consolidated net income (loss) as reported on its consolidated statement of operations. The accounting policies of the reportable segment are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on the consolidated balance sheet as total consolidated assets. The segment depreciation expense, interest expense, interest income, and segment asset additions are consistent with consolidated amounts reported within the consolidated statement of cash flows given the Company's operations are aggregated within a single reportable segment.
The Company has incurred operating losses since its inception and expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances its therapeutic candidates through all stages of development and clinical trials and, ultimately, seeks regulatory approval.
The CODM uses net loss and the components of operating expense to assess the Company’s operating results and performance and make operating decisions regarding the allocation of resources to best support the long-term growth of the Company’s overall business.
11
The table below summarizes the significant segment expenses which are regularly provided to the CODM for the purposes of making decisions regarding the allocation of resources and are reconciled to consolidated net loss for the three and six months ended June 30, 2026 and June 30, 2025 (in thousands):

Recent Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, or other standard setting bodies. The Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its condensed consolidated financial condition or results of operations upon adoption.
Recently Issued but Not Yet Adopted 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, which requires additional disclosure about specific expense categories in the notes to financial statements. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of this accounting standard update on the Company’s consolidated financial statements and related disclosures.

On January 13, 2025, the Company entered into a Loan and Security Agreement, or the 2025 Loan Agreement, with Oxford Finance LLC, or Oxford, pursuant to which it received $100.0 million in gross proceeds. The 2025 Loan Agreement provided for an additional tranche of $50.0 million to be funded upon the Company's request and at Oxford’s sole discretion. On March 18, 2026, the Company entered into the First Amendment to Loan and Security Agreement with Oxford, or the March 2026 Amendment, or collectively with the 2025 Loan Agreement, the Amended 2025 Loan Agreement. The March 2026 Amendment provided for an additional tranche, or the Term B Loans, in an aggregate principal amount of $75.0 million, upsized from $50.0 million originally available under the 2025 Loan Agreement. Upon closing of the March 2026 Amendment, the Term B Loans were funded and the Company received gross proceeds of $75.0 million.
The Company determined the March 2026 Amendment should be treated as a modification of the original 2025 Loan Agreement since the terms and resulting cash flows were not substantially changed upon the amendment.
The outstanding term loans will mature on January 1, 2030, or the Maturity Date, and bear interest at (1) 5.61 % plus (2) the greater of (i) the 1-Month Term Secured Overnight Financing Rate as published by the CME Group or (ii) 4.34 %. The repayment schedule provides for interest-only payments through February 1, 2028, with principal payments beginning on March 1, 2028. The interest-only period is followed by 23 months of equal payments of principal plus interest. Upon the earliest to occur of (i) the Maturity Date, (ii) the acceleration of any term loan under the Term Loan Facility, or (iii) prepayment of any term loan under the Term Loan Facility, the Company will be required to make a final payment of 9.0 % of the total principal amount. This final payment of $15.75 million will be accreted over the life of the Amended 2025 Loan Agreement using the effective interest method. The Company has the option to prepay the outstanding balance of the term loan in full prior to the Maturity Date, subject to a prepayment fee ranging from 2.0 % to 5.0 %, depending on the timing of the prepayment.

All obligations under the Amended 2025 Loan Agreement and the other loan documents are secured by a first priority perfected lien on, and security interest in, substantially all present and future assets of the Company, subject to certain exceptions. The Amended 2025 Loan Agreement includes customary events of default, including instances of a material adverse change in the Company’s operations, that may require prepayment of the outstanding term loans. The March 2026 Amendment updated the minimum liquidity threshold covenant, tested at all times, to $40.0 million, not subject to future increases. All other terms of the 2025 Loan Agreement remain outstanding following the March 2026 Amendment. As of June 30, 2026, the Company is in compliance with all covenants under the 2025 Loan Agreement and has not received any notification or indication from Oxford of an intent to declare the loan due prior to maturity.
Concurrently with the debt issuance in January 2025, the Company issued to Oxford warrants to purchase 140,741 shares of common stock at an exercise price of $14.21 per share. Concurrently with the March 2026 Amendment, the Company issued to Oxford warrants to purchase 21,518 shares of common stock at an exercise price of $69.71 per share. Both the 2025 Oxford Warrants and 2026 Oxford Warrants are immediately exercisable, and the exercise period will expire 10 1.7 million and $1.3 million, respectively, as additional paid-in-capital and as a debt discount which will be accreted over the life of the Amended 2025 Loan Agreement using the effective interest method.
See Note 4 for further discussion of these warrants.
Interest Expense
Interest expense on the Amended 2025 Loan is calculated using the effective interest method and is inclusive of non-cash amortization of the debt discount and accretion of the final payment at an effective interest rate of 17.5 %. During the three months ended June 30, 2026, interest expense was $5.7 million, $1.3 million of which related to non-cash amortization of the debt discount and accretion of the final payment. During the six months ended June 30, 2026, interest expense was $9.2 million, $2.0 million of which related to non-cash amortization of the debt discount and accretion of the final payment. During the three months ended June 30, 2025, interest expense was $3.1 million,

License and Collaboration Agreements
Scithera License Agreement
On March 31, 2025, the Company entered into a License and Assignment Agreement, or the Scithera License Agreement, with Scithera, Inc., or Scithera, a biotechnology company that focuses on antibody-based molecules.
Pursuant to the Scithera License Agreement, the Company licensed to Scithera the right to use certain assets in the Company’s antibody library to research, develop, and commercialize antibody-based molecules to certain targets. Additionally, the Company assigned to Scithera its agreement with NorthStar Medical Technologies, LLC for the development of radiopharmaceuticals for the treatment of cancer. The Company also agreed to make available to Scithera certain research materials useful for identifying, generating, and developing antibodies from antibody libraries to enable Scithera’s use of the assets licensed under the Scithera License Agreement.
Contingent upon Scithera’s achievement of specified funding events, Scithera was required to pay the Company $1.3 million as a non-refundable payment. In addition, Scithera may make additional future milestone payments of up to an aggregate of $41.25 million per target upon the achievement of certain milestone events, and potential royalty payments on net sales in the low- to mid-single digits.
As of the effective date of the agreement, the Company identified one performance obligation, which was the transfer of licenses to Scithera for the specified assets and all related materials and know-how. During the second quarter of 2025, Scithera achieved the specified funding event and made a non-refundable payment of $1.3 million to the Company. Upon notice of the achievement of such funding event, the Company re-assessed the transaction price to be $1.3 million, which was allocated to the single performance obligation. All remaining consideration under the agreement is variable consideration associated with the achievement of specified development milestones, and as a result, has been fully constrained (excluded) from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be reassessed at each reporting period.
During the three and six months ended June 30, 2025, the Company completed its single performance obligation and recognized $1.3 No

Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report contains forward-looking statements that involve risk and uncertainties, including those described in the section titled “Special Note Regarding Forward-Looking Statements.” As a result of many factors, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
We are a clinical-stage biopharmaceutical company with a pipeline of novel biologic therapeutic candidates, developed using our proprietary modular protein engineering platforms. We leverage our innovative protein engineering technologies and deep understanding of target biology to create therapeutic candidates with attributes and mechanisms we believe to be superior to current approaches and applicable to a range of challenging, validated targets with high potential.
Current Clinical Pipeline
Our current clinical pipeline of therapeutic candidates includes ozekibart and INBRX-106, both of which utilize our multivalent formats where the precise valency can be optimized in a target-centric way to mediate what we believe to be the most appropriate agonist function:

ozekibart (INBRX-109)
Ozekibart is a precisely engineered tetravalent death receptor 5, or DR5, agonist currently being evaluated in patients diagnosed with colorectal cancer, Ewing sarcoma, chondrosarcoma, and certain other solid tumor types.
Colorectal adenocarcinoma
In April 2026, we announced interim data from the Phase 1/2 study evaluating ozekibart in combination with FOLFIRI in patients with locally advanced or metastatic, unresectable colorectal cancer, or CRC. Efficacy was assessed in 45 evaluable patients as of April 10, 2026, the cutoff date, and resulted in an ORR of 20% per RECIST v1.1 criteria. Historically, the current standard of care has yielded limited response rates (ORR of 1-6% per RECIST v1.1 criteria). Nearly half of responses were durable with a duration of response exceeding 6 months. Responses were observed irrespective of RAS/RAF mutation status. The median progression-free survival, or PFS, for the evaluable population was 5.5 months. Notably, 42% of patients remained progression-free at the 6-month landmark, with 9 patients remaining on therapy, suggesting that a significant portion of patients achieve durable disease control that extends well beyond the median PFS. The overall disease control rate (partial responses and stable disease as best response) remained robust at 87%, further supporting the potential of ozekibart to control tumor growth in a heavily pre-treated population. Ozekibart in combination with FOLFIRI continues to maintain a manageable safety profile. The most common treatment-related adverse events were diarrhea, fatigue, and nausea, which were largely Grade 1 or 2 and consistent with the known side effects of FOLFIRI. Despite the majority of the patients (68%) presenting with liver metastases at baseline, no significant liver toxicity was observed.
During the second quarter of 2026, we initiated two additional Phase 1 cohorts in CRC: (1) a second line study investigating ozekibart in combination with Folfiri and Avastin, and (2) a third/fourth line study investigating ozekibart in combination with Lonsurf and Avastin. We expect to announce interim results from these cohorts during the first quarter of 2027. We plan to meet with the FDA in the fourth quarter of 2026 to discuss our plans to initiate a first-line registrational trial in CRC, as well as the potential for an accelerated regulatory pathway for ozekibart in fourth-line CRC.
Ewing sarcoma
In November 2023, we announced interim efficacy and safety data from the cohort of the Phase 1/2 trial evaluating ozekibart in combination with Irinotecan, or IRI, and Temozolomide, or TMZ, for the treatment of advanced or metastatic, unresectable Ewing sarcoma. Overall, ozekibart in combination with IRI/TMZ was well tolerated from a safety perspective.
Based on this preliminary data, the ongoing Phase 1/2 trial in the Ewing sarcoma cohort was expanded to enroll up to an additional 50 patients. In March 2026, we provided an update at the European Society for Medical Oncology (ESMO) Sarcoma and Rare Cancers Congress. Of the 31 patients evaluable based on a cutoff date of January 15, 2026, we observed a 64.5% ORR and a disease control rate of 87.1%. At the time of the presentation, responses were ongoing in eight patients, one of which had been on treatment and progression free for more than two years.
We expect to complete enrollment in the Phase 1/2 trial of ozekibart in combination with IRI/TMZ for advanced or metastatic, unresectable, relapsed, or refractory Ewing sarcoma in 2027. We are evaluating the submission of clinical data to the National Comprehensive Cancer Network® (NCCN®) to consider ozekibart for potential inclusion in the NCCN Guidelines® as a treatment option for Ewing sarcoma.
Chondrosarcoma
In June 2021, we initiated a randomized, blinded, placebo-controlled, registrational trial in patients with metastatic, unresectable conventional chondrosarcoma, which enrolled over 200 patients in total at 68 different sites worldwide and for which the United States Food and Drug Administration, or FDA, and the European Medicines Agency, or EMA, granted orphan drug designation for the treatment of chondrosarcoma in November 2021 and August 2022, respectively. The primary endpoint for this trial was PFS.
In October 2025, we announced this trial met its primary endpoint of a statistically significant and clinically meaningful median PFS for patients with advanced or metastatic chondrosarcoma treated with ozekibart compared to placebo. Ozekibart achieved a 52% reduction in the risk of disease progression or death compared to placebo
21
(stratified Hazard Ratio 0.479; 95% CI: 0.33, 0.68); P<0.0001), more than doubling median PFS to 5.52 months versus 2.66 months for placebo. Importantly, ozekibart is the first investigational therapy to demonstrate a significant PFS benefit in a randomized trial for chondrosarcoma, a disease with no approved systemic options.
In June 2026, the FDA accepted for filing our biologics license application for the potential approval of ozekibart in conventional chondrosarcoma.
INBRX-106
INBRX-106 is a hexavalent OX40 agonist currently being investigated as a single agent and in combination with KEYTRUDA® (pembrolizumab), a PD-1 blocking checkpoint inhibitor, in patients with locally advanced or metastatic solid tumors. KEYTRUDA® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA. INBRX-106 is currently being investigated in combination with KEYTRUDA® in patients with non-small cell lung cancer, or NSCLC, head and neck squamous cell carcinoma, or HNSCC, among others.
In May 2026, we announced positive interim results from the randomized, first-line Phase 2 portion of the HexAgon study. The trial evaluated the safety and efficacy of INBRX-106 in combination with pembrolizumab (the combination arm) versus pembrolizumab monotherapy (the control arm) in first-line patients with treatment-naïve, PD-L1 positive (CPS ≥ 20) metastatic or unresectable recurrent HNSCC. The Phase 2 portion of the HexAgon study enrolled 68 patients: 33 randomized to the combination arm and 35 to the control arm. In the evaluable population, 11 out of 25 patients (44.0%) in the INBRX-106 combination arm achieved a confirmed objective response, compared with 6 out of 28 patients (21.4%) in the control arm. This represented a 22.6% absolute increase in confirmed responses. Three complete responses were observed in the INBRX-106 combination arm, reflecting tumor clearance, while no complete responses were observed with pembrolizumab alone. Complete responses in first-line HNSCC remain uncommon and are generally associated with more durable outcomes. The combination of INBRX-106 and pembrolizumab was generally manageable, with a safety profile consistent with the addition of an active immunostimulatory agent to checkpoint blockade. The most common treatment-related adverse events were rash, diarrhea, fatigue, and infusion-related reactions, which were predominantly low-grade. No treatment-related deaths were reported in either arm.
The progression-free survival data from the Phase 2 portion of the HexAgon study are expected to become available in the third quarter of 2026. We plan to begin the Phase 3 portion of the HexAgon study during the third quarter of 2026.
Based on these promising early results, we aim to evaluate INBRX-106 across broader indications to potentially improve the efficacy of checkpoint inhibitors. This strategy includes initiating a study in the perioperative setting in NSCLC. We believe OX40 agonism has the greatest potential to drive cure in earlier-stage disease settings, where patients typically retain a more active and responsive immune system. Outside of combination with checkpoint inhibitors, we plan to explore combinations with agents that could benefit from T-cell costimulation, such as vaccines, T-cell engagers, and CAR-Ts.
Components of Results of Operations
Revenue
As of the date of this Quarterly Report, all of our revenue has been derived from licenses with collaboration partners and grant awards. We have not generated any revenue from the commercial sale of approved therapeutic products to date.
Operating Expenses
Research and Development
As of the date of this Quarterly Report, our research and development expenses have related primarily to research activities, including our discovery efforts, and preclinical and clinical development and the manufacturing of our therapeutic candidates. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.
22
In accordance with the applicable accounting and regulatory requirements, we track all research and development expenses in the aggregate and do not manage or track either external or internal expenses on a program-by-program basis. External research and development expenses are instead managed and tracked by the nature of the activity, and primarily consist of contract manufacturing and clinical trial expenses. Internal research and development expenses primarily relate to personnel, early research and consumable costs, which are deployed across multiple projects under development. We manage and prioritize our research and development expenses based on scientific data, probability of successful technical development and regulatory approval, market potential and unmet medical need, among other considerations. We regularly review our research and development activities and, as necessary, reallocate resources that we believe will best support the long-term growth of our overall business. We review expenses incurred by vendor and by contract as benchmarked against the progression of our clinical and other milestones.
External research and development expenses consist of:
•expenses incurred in connection with the preclinical development of our programs;
•clinical trials of our therapeutic candidates, including under agreements with third parties, such as consultants and contract research organizations, or CROs;
•expenses associated with the manufacturing of our therapeutic candidates under agreements with contract development and manufacturing organizations, or CDMOs;
•expenses associated with regulatory requirements, including fees and other expenses related to our Scientific Advisory Board; and
•other external expenses, such as laboratory services related to our discovery and development programs and other shared services.
Internal research and development expenses consist of:
•salaries, benefits and other related costs, including non-cash stock-based compensation under the 2024 Omnibus Incentive Plan, or the 2024 Plan, for personnel engaged in research and development functions;
•facilities, depreciation and other expenses, which include direct and allocated expenses for depreciation and amortization, rent and maintenance of facilities; and
•other internal expenses, such as laboratory supplies and other shared research and development costs.
We expect that research and development expense will continue to increase over the next several years as we continue development of our therapeutic candidates currently in clinical stage development and support our preclinical programs. In particular, clinical development of our therapeutic candidates, as opposed to preclinical development, generally has higher development costs, primarily due to the increased size and duration of later-stage clinical trials. Moreover, the costs associated with our CDMOs to manufacture our therapeutic candidates and future commercial products is also much more costly as compared to early-stage preclinical development. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future preclinical studies and clinical trials of our therapeutic candidates due to the inherently unpredictable nature of preclinical and clinical development. Preclinical and clinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which therapeutic candidates to pursue and how much funding to direct to each therapeutic candidate on an ongoing basis in response to the results of ongoing and future preclinical studies and clinical trials, regulatory developments, and our ongoing assessments as to each therapeutic candidate’s commercial potential. We will need substantial additional capital in the future to support these efforts. In addition, we cannot forecast which therapeutic candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.
Our clinical development costs may vary significantly based on factors such as:
•the per patient trial costs;
•the number of trials required for approval;
•the number of sites included in the trials;
23
•the countries in which the trials are conducted;
•the length of time required to enroll eligible patients;
•the number of patients that participate in the trials;
•the ability to identify patients eligible for our clinical trials;
•the number of doses that patients receive;
•the drop-out or discontinuation rates of patients;
•the potential additional safety monitoring requested by regulatory agencies;
•the duration of patient participation in the trials and follow-up;
•the cost, timing, and successful manufacturing of our therapeutic candidates;
•the phase and development of our therapeutic candidates;
•the efficacy and safety profile of our therapeutic candidates;
•the timing, receipt, and terms of any approvals from applicable regulatory authorities including the FDA and non-U.S. regulators;
•maintaining a continued acceptable safety profile of our therapeutic candidates following approval, if any;
•significant and changing government regulation and regulatory guidance;
•the ability to attract and retain personnel;
•the impact of any business interruptions to our operations or to those of the third parties with whom we work;
•the uncertainties related to potential economic downturn, inflation, interest rates, geopolitical events and widespread health events on capital and financial markets, the supply chain and our expenses; and
•the extent to which we establish additional strategic collaborations or other arrangements.
General and Administrative
General and administrative, or G&A, expenses consist primarily of:
•salaries, benefits and other related costs, including non-cash stock-based compensation under the 2024 Plan, for personnel engaged in G&A functions;
•expenses incurred in connection with accounting, audit, and tax services, legal services, including costs associated with obtaining and maintaining our patent portfolio, investor relations and consulting expenses under agreements with third parties, such as consultants and contractors;
•expenses incurred in connection with commercialization and business development activity; and
•facilities, depreciation and other expenses, which include direct and allocated expenses for depreciation and amortization, rent and maintenance of facilities, insurance and supplies.
We expect certain of our G&A expenses will continue to increase in the future to support our continued research and development activities, including costs related to pre-commercialization and business development activities. Additionally, we will continue to incur other professional service fees, including but not limited to, legal costs associated with the filing, prosecution, and maintenance of our patents for our therapeutic candidates, and other legal matters, as well as costs associated with services for compliance, accounting, legal, regulatory, tax, investor and public relations.
Other Income (Expense)
Interest expense. Interest expense consists of interest on our 2025 Loan Agreement, as amended, with Oxford Finance LLC and other lenders, or collectively, Oxford.
Interest income. Interest income consists of interest earned on cash and cash equivalents.

Research and development expenses increased by $1.6 million from $22.3 million during the three months ended June 30, 2025 to $23.9 million during the three months ended June 30, 2026. The overall increase was primarily due to the following factors:
•contract manufacturing expense increased by $1.6 million due to the timing of certain manufacturing activities required to support our clinical trials for ozekibart (INBRX-109) and INBRX-106, including the initiation of certain activities associated with our filing of the BLA for potential approval of ozekibart (INBRX-109) in conventional chondrosarcoma;
•clinical trial expense increased by $1.2 million due to the progression of our clinical trials for ozekibart (INBRX-109) and INBRX-106 and the timing of the completion of enrollment in our trial for ozekibart (INBRX-109) for the treatment of unresectable or metastatic conventional chondrosarcoma;
•personnel-related expense decreased by $0.6 million, which was primarily related to a decrease in headcount; and
•other research and development expenses decreased by $0.5 million, primarily due to a decrease in clinical consulting services.
G&A Expense
General and administrative expenses increased by $1.8 million from $6.4 million during the three months ended June 30, 2025 to $8.2 million during the three months ended June 30, 2026. The overall increase was primarily due to the following factors:
•pre-commercialization expenses increased by $1.6 million, which was primarily related to the progression of our potential commercialization strategy surrounding market access and launch and the development of communication materials for ozekibart (INBRX-109) in conventional chondrosarcoma; and
•personnel-related expense increased by $0.4 million, which was primarily related to an increase in stock options outstanding during the period.
Other income (expense)
Interest expense. Interest expense was $5.7 million and $3.1 million during the three months ended June 30, 2026 and June 30, 2025, respectively, all of which related to interest incurred and the amortization of debt discounts related to the 2025 Loan Agreement, as amended. We incurred increased interest expense on the $175.0 million in principal outstanding during the three months ended June 30, 2026 following the March 2026 Amendment, upon which we received an additional $75.0 million in gross proceeds, as compared to the $100.0 million in principal outstanding during the three months ended June 30, 2025.
Interest income. During the three months ended June 30, 2026 and June 30, 2025, we earned $1.3 million and $2.1 million, respectively, of interest income related to interest earned on our sweep and money market account balances. The decrease in interest income is due to lower average cash balances and decreased interest rates.

Research and development expenses decreased by $10.0 million from $59.1 million during the six months ended June 30, 2025 to $49.1 million during the six months ended June 30, 2026. The overall decrease was primarily due to the following factors:
•clinical trial expense decreased by $2.9 million, primarily due to a decrease in expense associated with the ozekibart (INBRX-109) trial for the treatment of unresectable or metastatic conventional chondrosarcoma as the trial approached completion of enrollment;
•contract manufacturing expense decreased by $4.9 million primarily due to the timing and completion of certain manufacturing activities required to support our clinical trials for ozekibart (INBRX-109) and INBRX-106, offset in part by the initiation of certain activities associated with our filing of the BLA for potential approval of ozekibart (INBRX-109) in conventional chondrosarcoma;
•personnel-related expense decreased by $1.4 million, which was primarily related to a decrease in headcount; and
•other research and development expense decreased by $0.7 million, which was primarily attributable to a decrease in preclinical studies and the associated lab supplies and materials for research efforts.
G&A Expense
G&A expenses increased by $1.5 million from $12.5 million during the six months ended June 30, 2025 to $14.0 million during the six months ended June 30, 2026. The overall increase during the six months ended June 30, 2026, was primarily due to the following factors:
•pre-commercialization expenses increased by $1.6 million, which was primarily related to the progression of our potential commercialization strategy surrounding market access and launch and the development of communication materials for ozekibart (INBRX-109) in conventional chondrosarcoma;
•personnel-related expenses increased by $0.3 million, which was primarily related to an increase in stock options outstanding during the period; and
•professional service fees decreased by $0.2 million, primarily due to a decrease in legal, accounting, and other consulting services.
Other Expense
Interest expense. Interest expense was $9.2 million and $5.8 million during the six months ended June 30, 2026 and June 30, 2025, respectively, all of which related to interest incurred and the amortization of debt discounts related to the 2025 Loan Agreement, as amended. We incurred increased interest expense on the $175.0 million in principal outstanding during the six months ended June 30, 2026 following the March 2026 Amendment, upon which we received an additional $75.0 million in gross proceeds, as compared to the $100.0 million in principal outstanding during the six months ended June 30, 2025.
Interest income. During the six months ended June 30, 2026 and June 30, 2025, we earned $2.3 million and $4.5 million, respectively, of interest income related to interest earned on our sweep and money market account balances. The decrease in interest income is due to lower average cash balances and decreased interest rates.
Liquidity, Capital Resources and Financial Condition
Sources of Liquidity
As of the date of this Quarterly Report, sources of capital raised to fund our operations have been comprised of the sale of equity securities, borrowings under our prior loan and security agreements, payments received from commercial partners for licensing rights to our therapeutic candidates under development, grants, and proceeds from the sale and issuance of convertible promissory notes.
In January 2025, we entered into the 2025 Loan Agreement with Oxford Finance LLC, or Oxford, upon which we received gross proceeds of $100.0 million, or the Term A Loan. On March 18, 2026, we entered into the First Amendment to Loan and Security Agreement with Oxford, or the March 2026 Amendment. The March 2026 Amendment provided for an additional tranche, or the Term B Loan, in an aggregate principal amount of $75.0 million, upsized from $50.0 million originally available under the 2025 Loan Agreement. Upon closing of the March 2026 Amendment, the Term B Loan was funded and we received gross proceeds of $75.0 million. On July 15, 2026, we entered into the Second Amendment to Loan and Security Agreement with Oxford, or the July 2026 Amendment, or collectively with the 2025 Loan Agreement and the March 2026 Amendment, the Amended 2025
28
Loan Agreement. The July 2026 Amendment provides for the funding of up to an additional $325.0 million in gross proceeds, $100.0 million of which we received upon execution of the amendment, or the Term C Loan, with up to an additional $225.0 million to be funded in increments of $50.0 million or more upon the Company’s request and at the Lenders’ sole discretion, or the Term D Loan.
Future Funding Requirements
Since our inception, we have devoted substantially all of our efforts to therapeutic drug discovery and development, conducting preclinical studies and clinical trials, enabling manufacturing activities in support of our therapeutic candidates, pre-commercialization activities, organizing and staffing the Company, establishing our intellectual property portfolio, and raising capital to support and expand these activities. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses. Our net income or losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenditures on other research and development activities, as well as the timing of other corporate transactions. During the six months ended June 30, 2026 our net loss was $70.1 million. As of June 30, 2026, we had an accumulated deficit of $316.3 million and cash and cash equivalents of $133.3 million.
Based upon our current operating plans, we believe that our existing cash and cash equivalents will be sufficient to fund our operations for at least the next 12 months from the date of filing of this Quarterly Report. Our forecast of the period through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we expect.
The process of conducting preclinical studies and testing therapeutic candidates in clinical trials is costly, and the timing of progress and expenses in these studies and trials is uncertain. We expect to continue to incur net losses for the foreseeable future until, if ever, we have an approved product and can successfully commercialize it. We expect our research and development expenses to increase as we continue our development of, and seek marketing approvals for, our therapeutic candidates (especially as we move more candidates into later stages of clinical development), and begin to commercialize any approved products, if ever. At this time, we are preparing to proceed with the commercialization of certain of our therapeutic candidates, if ever approved. As a result, we will incur significant pre-commercialization expenses in preparation for launch, the outcome of which is uncertain. Additionally, if approved, we will incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution.
Until such time we, if ever, can generate substantial product revenue, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, including strategic licensing and collaborations, strategic transactions, or other similar arrangements and transactions, and from time to time, we engage in discussions with potential acquirers regarding the disposition of one or more of our therapeutic candidates. If the Company does raise additional capital through public or private equity or convertible debt offerings, the ownership interests of its existing stockholders will be diluted, and the terms of those securities may include liquidation or other preferences that adversely affect its stockholders’ rights. If the Company raises capital through additional debt financings, it may be subject to covenants limiting or restricting its ability to take specific actions, such as incurring additional debt or making certain capital expenditures. To the extent that the Company raises additional capital through strategic licensing, collaboration or other similar agreements, it may have to relinquish valuable rights to its therapeutic candidates, future revenue streams or research programs at an earlier stage of development or on less favorable terms than it would otherwise choose, or to grant licenses on terms that may not be favorable to the Company. However, there can be no assurance as to the availability or terms upon which such finances or capital might be available in the future. If we are unable to secure adequate additional funding, we will need to reevaluate our operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, delay, scale back or eliminate some or all of our development programs, or relinquish rights to our intellectual property on less favorable terms than we would otherwise choose. These actions could materially impact our business, results of operations, financial condition, and prospects.
Our future liquidity and capital funding requirements will depend on numerous factors, including:
29
•the outcome, costs and timing of preclinical studies and clinical trials for our current or future therapeutic candidates;
•whether and when we are able to obtain marketing approval to market any of our therapeutic candidates and the outcome of meetings with applicable regulatory agencies, including the FDA;
•our ability to successfully commercialize, including the costs and timing of manufacturing, any therapeutic candidates that receive marketing approval;
•the emergence and effect of competing or complementary therapeutics or therapeutic candidates;
•our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;
•our ability to retain our current employees and the need and ability to hire additional management and scientific and medical personnel;
•the costs and timing of establishing or securing sales and marketing capabilities if any current or future therapeutic candidate is approved;
•the terms and timing of any strategic licensing, collaboration or other similar agreement that we have established or may establish;
•our ability to achieve market acceptance, coverage and adequate reimbursement from third-party payors and adequate market share and revenue for any approved therapeutics;
•our ability to repay, refinance or restructure when payment is due any indebtedness we might incur, including in the event such indebtedness is accelerated;
•the valuation of our capital stock; and
•the continuing or future effects of a potential economic downturn, inflation, interest rates, geopolitical events, and widespread health events on capital and financial markets, the supply chain and our expenses.
We do not own or operate manufacturing and testing facilities for the production of any of our therapeutic candidates, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We currently rely on a limited number of third-party contract manufacturers for all of our required raw materials, antibodies and other biologics for our preclinical research, clinical trials, and if and when applicable, commercial product, and employ internal resources to manage our manufacturing relationships with these third parties.
Commitments
Our material cash requirements from known contractual and other obligations primarily relate to our lease obligations, debt, and services provided by our third party CROs and CDMOs.
Our lease for our laboratory and office space expires in 2028, with an option to extend for an additional three years. As of June 30, 2026, we had future minimum rental payments under these leases of $5.9 million, of which $2.9 million and $3.0 million are current and non-current, respectively. For more information regarding these lease agreements, refer to Note 7 to the unaudited condensed consolidated financial statements.
Under the 2025 Loan Agreement, as amended, we are required to make interest only payments through February 2028, with all principal payments and final fee payments beginning in March 2028 and continuing through the maturity date of January 2030. As of June 30, 2026, we have a minimum obligation of $237.9 million of long-term debt, including minimum interest and final fee payments, of which $17.7 million and $220.2 million are current and non-current, respectively. For more information regarding the Amended 2025 Loan Agreement, refer to Note 3 to the condensed consolidated financial statements.
30
We enter into contracts in the normal course of business with CROs related to our ongoing preclinical studies and clinical trials and with CDMOs for clinical supplies and manufacturing scale-up activities. These contracts are generally cancellable, with notice, at our option. We have recorded accrued expenses of approximately $6.6 million in our condensed consolidated balance sheets for expenditures incurred by CROs and CDMOs as of June 30, 2026.
While these contracts are generally cancellable, some may contain specific activities that involve one or more noncancellable commitments. Depending on the timing and reasoning of the exit, certain termination penalties may apply and can range from the cost of work performed to date up to twelve months of future committed manufacturing costs. As of June 30, 2026, the noncancellable portion of these contracts totaled in aggregate, excluding amounts recorded in accounts payable and accrued expenses as of this date, approximately $15.9 million. The noncancellable purchase commitments relate to future contract manufacturing of drug supply for one of our therapeutic candidates.

Operating Activities
Net cash used in operating activities was $67.9 million during the six months ended June 30, 2026 and consisted primarily of a net loss of $70.1 million, adjusted for non-cash items, including accretion on our debt discount and the non-cash portion of interest expense related to our debt of $2.0 million, stock-based compensation expense of $5.8 million, depreciation and amortization of $1.1 million and non-cash lease expense of $1.0 million. Changes in operating assets and liabilities also contributed to the cash used in operating activities, including the decrease in operating lease liability of $1.1 million as a result of lease payments made throughout the period, and an increase in prepaid expenses and other current assets of $0.7 million and a decrease in accrued expenses of $9.8 million due to the timing of payments to our CRO and CDMO partners during the period. These uses of cash were offset in part by an increase in accounts payable of $3.8 million during the period.
Net cash used in operating activities was $65.8 million during the six months ended June 30, 2025 and consisted primarily of a net loss of $72.0 million, adjusted for non-cash items, including accretion on our debt discount and the non-cash portion of interest expense related to our debt of $1.2 million, stock-based compensation expense of $5.2 million, depreciation and amortization of $1.3 million and non-cash lease expense of $0.9 million. Changes in operating assets and liabilities also contributed to the cash used in operating activities, including the decrease in operating lease liability of $0.5 million as a result of lease payments made throughout the period, an increase in accounts receivables and other receivables of $0.6 million, and decreases in accounts payable of $1.0 million and accrued expenses of $1.4 million due to the timing of payments to our CRO and CDMO partners during the period. These uses of cash were offset in part by a decrease in prepaid expenses and other current assets of $1.0 million.
Investing Activities
Net cash used in investing activities was approximately $21,000 during the six months ended June 30, 2025, and was related to capital purchases of laboratory equipment. We did not use any cash in investing activities during the six months ended June 30, 2026.
Financing Activities
Net cash provided by financing activities was $77.1 million during the six months ended June 30, 2026, which consisted of $75.0 million in net proceeds from the March 2026 Amendment and $2.1 million in proceeds from the exercise of stock options. Net cash provided by financing activities was $99.8 million during the six months ended June 30, 2025, which consisted of net proceeds from the 2025 Loan Agreement which we entered into in January 2025.
Critical Accounting Estimates and Policies
Our consolidated financial statements and accompanying notes are prepared in accordance with United States generally accepted accounting principles, or GAAP, which requires management to make estimates and assumptions that affect the amounts reported. Management bases its estimates on historical experience, market and other conditions, and various other assumptions it believes to be reasonable. Although these estimates are based on management’s best knowledge of current events and actions that may impact us in the future, the estimation process is, by its nature, uncertain given that estimates depend on events over which we may not have control. If market and other conditions change from those that we anticipate, our consolidated financial statements may be materially affected. In addition, if our assumptions change, we may need to revise our estimates, or take other corrective
32
actions, either of which may also have a material effect in our consolidated financial statements. We review our estimates, judgments, and assumptions used in our accounting practices periodically and reflect the effects of revisions in the period in which they are deemed to be necessary. We believe that these estimates are reasonable; however, our actual results may differ from these estimates.
There have been no material changes to our critical accounting policies and estimates from those disclosed in our financial statements and the related notes and other financial information included in the 2025 Annual Report.
Emerging Growth Company
We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act, or the JOBS Act, enacted in 2012. As such, we are eligible for exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including, but not limited to, presenting only two years of audited financial statements, not being required to comply with the auditor attestation requirements of Section 404, reduced disclosure obligations regarding executive compensation, and an exemption from the requirements to obtain a non-binding advisory vote on executive compensation or golden parachute arrangements.
In addition, an emerging growth company can take advantage of an extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. We have irrevocably elected not to avail ourselves of this exemption and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.
In light of the market value of our common stock held by non-affiliates as of June 30, 2026, we expect that we will no longer be an emerging growth company effective on December 31, 2026.
Smaller Reporting Company Status
Additionally, we are a “smaller reporting company,” as defined in Rule 12b-2 under the Exchange Act. As such, we are eligible for exemptions from various reporting requirements applicable to other public companies that are not smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation.
We will remain a smaller reporting company as long as either: (i) the market value of the shares of our common stock held by non-affiliates is less than $250.0 million as of the last business day of our most recently completed second fiscal quarter; or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of the shares of our common stock held by non-affiliates is less than $700.0 million as of the last business day of our most recently completed second fiscal quarter.
In light of our annual revenue during 2025 and the market value of the shares of our common stock held by non-affiliates as of June 30, 2026, we expect that we will no longer be a smaller reporting company beginning with our Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2027. Based on recent SEC guidance, we will, however, continue to be a non-accelerated filer through at least our fiscal year ending December 31, 2027.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure.
Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures were designed and operating effectively at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 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 Chief Executive Officer and our Chief Financial Officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. In addition, the design of any system of controls 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 deterioration in the degree of compliance with policies or procedures.

Part II — Other Information
Item 1. Legal Proceedings.
We are not currently a party to any material legal proceedings. From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. Regardless of outcome, litigation can have an adverse impact on us due to defense and settlement costs, diversion of management resources, negative publicity, reputational harm and other factors, and there can be no assurances that favorable outcomes will be obtained.
Item 1A. Risk Factors.
Except for the risk factor set forth below, there have been no material changes to the risk factors set forth in Part I, Item 1A of our 2025 Annual Report and in Part II, Item 1A of our Quarterly Report for the three months ended March 31, 2026.
We depend heavily on the success of our therapeutic candidates, which are currently in various stages of development and may fail or suffer delays that materially and adversely affect their commercial viability. If we are unable to advance our therapeutic candidates through clinical development, obtain marketing approval and ultimately commercialize our therapeutic candidates, or experience significant delays in doing so, our business will be materially harmed. Even if our therapeutic candidates receive regulatory approval and are commercialized, there is no assurance that our commercialization efforts will be successful.
We currently have no products on the market and our ability to achieve and sustain profitability depends on obtaining marketing approvals for and successfully commercializing our therapeutic candidates. We have two therapeutic candidates, ozekibart (INBRX-109) and INBRX-106, currently in active clinical trials. While our BLA for ozekibart in patients with metastatic or unresectable conventional chondrosarcoma has been filed and is under review by FDA, there is no assurance that we will be successful in our efforts to gain U.S. regulatory approval on the timeline we expect or at all. The FDA may not agree that the clinical and preclinical data we have generated to date are sufficient to gain regulatory approval to commercialize ozekibart in the United States. The FDA may, despite prior advice, determine that additional trials or data are necessary in order to obtain approval. Regulatory authorities may find fault with the data generated at our clinical sites or with the activities of our trial monitor or may disagree with our analyses of the results of our trials. Regulatory authorities may also identify deficiencies or other issues with our manufacturing or quality systems or processes. Any such findings or issues could require additional data or analyses or the need for changes to our systems or processes that could delay or prevent us from gaining approval of ozekibart. For example, during FDA clinical inspections in connection with review of the BLA, Form 483 observations have been issued to us and to some ChonDRAgon clinical investigators. While corrective and preventive actions have been implemented in conjunction with those inspectional observations by us and our investigators, there can be no assurance those observations do not contribute to delay of BLA review or issuance of a complete response letter.
Clinical and preclinical development is expensive and can take many years to complete, and its outcome is inherently uncertain. We cannot guarantee that any clinical trials or preclinical studies will be conducted as planned, including whether we will be able to meet expected timeframes for data readouts, or completed on schedule, if at all, and failure can occur at any time during the trial or study process. Despite promising preclinical or clinical results, any therapeutic candidate can unexpectedly fail at any stage of clinical or preclinical development. The historical failure rate for therapeutic candidates in our industry is high, particularly in the earlier stages of development. Before obtaining marketing approval for the commercial distribution of our therapeutic candidates, we must conduct extensive preclinical tests and clinical trials to demonstrate sufficient safety and efficacy of our therapeutic candidates in patients.
Before we can initiate clinical trials for any therapeutic candidates, we must submit the results of preclinical studies to the FDA or comparable foreign regulatory authorities along with other information, including information about the candidate’s chemistry, manufacturing and controls and our proposed clinical trial protocol, as part of an Investigational New Drug Application, or IND, or similar regulatory submission. The FDA or comparable foreign regulatory authorities may require us to conduct additional preclinical studies for any therapeutic candidate before it
35
allows us to initiate clinical trials under any IND or similar regulatory submission, which may lead to delays and increase the costs of our development programs.
Moreover, failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful. If we experience additional delays or fail to develop or terminate development of a therapeutic candidate in our pipeline, we may not have the financial resources to continue development of, or to modify existing or to enter into new license or collaboration for, a therapeutic candidate. Other issues that may again delay or potentially prevent us from completing our ongoing and planned clinical trials, include:
•inability to generate sufficient preclinical toxicology, or other in vivo or in vitro data to support the initiation or continuation of clinical trials;
•obtaining allowance or approval from regulatory authorities to commence a trial or reaching a consensus with regulatory authorities on trial design;
•the FDA or comparable foreign regulatory authorities disagreeing as to the design or implementation of our clinical trials;
•any failure or delay in reaching an agreement with contract research organizations, or CROs, and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
•delays in identifying, recruiting and training suitable clinical investigators;
•obtaining approval from one or more institutional review boards, or IRBs, or ethics committees at clinical trial sites;
•IRBs suspending or terminating the trial at an investigational site, precluding enrollment of additional subjects, or withdrawing their approval of the trial;
•changes or amendments to the clinical trial protocol;
•clinical sites deviating from the trial protocol or dropping out of a trial;
•failure by our CROs to perform in accordance with Good Clinical Practice, or GCP, requirements or applicable regulatory rules and guidelines in other countries;
•manufacturing sufficient quantities of our therapeutic candidates, or in obtaining sufficient quantities of combination therapies for use in clinical trials;
•subjects failing to enroll or remain in our trials at the rate we expect, or failing to return for post-treatment follow-up, including subjects failing to remain in our trials;
•lack of adequate funding to continue a clinical trial, or costs being greater than we anticipate;
•subjects experiencing severe or serious unexpected drug-related adverse effects;
•occurrence of serious adverse events in trials of the same class of agents conducted by other companies that could be considered similar to our therapeutic candidates;
•selection of clinical endpoints that require prolonged periods of clinical observation or extended analysis of the resulting data;
•delays or failure by our contract manufacturers or us to make any necessary changes to such manufacturing process, or failure of our contract manufacturers to produce clinical trial materials in accordance with cGMPs, regulations or other applicable requirements; and
•third parties being unwilling or unable to satisfy their contractual obligations to us in a timely manner.
The therapeutic candidates we pursue may not demonstrate the necessary safety or efficacy requirements for marketing approval.
A clinical trial may be suspended, partially suspended or terminated by us, the IRBs overseeing such trials, the Data Safety Monitoring Board for such trial or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold or partial clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug or therapeutic biologic, changes in governmental regulations, administrative actions or lack of adequate funding to continue the clinical trial. Clinical holds may be placed prior to a clinical trial even beginning, in order to address potential safety and risk concerns of regulatory authorities, and partial or complete clinical holds can be imposed at any time during a trial. For example, in early 2023, the ChonDRAgon trial of ozekibart was placed on partial clinical hold by the FDA, and the Former Parent paused patient enrollment in the
36
trial, following the occurrence of a fatal serious adverse event (grade 5) of hepatotoxicity (or hepatic failure) triggering the predefined stopping rules built into the protocol. The FDA lifted the hold in April 2023 after the Former Parent amended the trial protocol to include additional screening criteria and to make other changes to address patients who may be at risk of significant hepatotoxicity. Furthermore, while we perform certain similar functions internally, we expect to rely on contract research organizations, or CROs, and clinical trial sites to ensure proper and timely conduct of our clinical trials and while we expect to enter into and have entered into agreements governing those CROs’ committed activities, we have limited influence over their actual performance.
If we experience delays in the completion of, or termination of, any clinical trial of our therapeutic candidates, the commercial prospects of our therapeutic candidates may be harmed, and our ability to generate product revenue or receive royalties from any of these therapeutic candidates may be delayed. Any delays in completing our clinical trials may increase our costs, slow down our product development and approval process and jeopardize our ability to commence product sales and generate revenue. If we were to cancel the development of any of our therapeutic candidates, we may still be required to pay certain non-cancellable commitments to our CROs under the terms of our various CRO contracts. Any of these occurrences may materially and adversely affect our business, financial condition, results of operations and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing approval of our therapeutic candidates.
Even if we obtain approval of ozekibart, we may never be able to successfully commercialize the product or to meet our expectations with respect to revenues or profits. We have never marketed, sold or distributed for commercial use any pharmaceutical product. We are in the process of building the teams, infrastructure, systems, processes, policies, relationships and materials necessary for launch of ozekibart in the United States in chondrosarcoma. If we receive regulatory approval to market or sell ozekibart or any of our other therapeutic candidates, if successfully developed and approved, but are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, or if we are unable to do so on commercially reasonable terms, our business, results of operations, financial condition and prospects will be materially adversely affected. There is no guarantee that we will be successful in our launch or commercialization efforts with respect to ozekibart or with respect to any other therapeutic candidate that may be approved in the future. We may encounter issues, delays or unexpected challenges in launching or commercializing ozekibart or any of our other therapeutic candidates, if approved. For example, our results may be negatively impacted if we have not adequately sized our field teams or our physician segmentation and targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes. We may encounter unexpected limitations in the scope, breadth, availability or amount of reimbursement covering ozekibart or our other therapeutic candidates, if approved, or other limitations or issues related to the price. We may face issues related to market acceptance and use of any of our therapeutic candidates, if approved. Any of these issues could impair our ability to successfully commercialize the product or to generate substantial revenues or profits or to meet our expectations with respect to revenues or profits.
