• Biologics License Application for cosibelimab under review by U.S. FDA
• PDUFA goal date of December 28, 2024

WALTHAM, Mass., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Checkpoint Therapeutics, Inc. (“Checkpoint”) (Nasdaq: CKPT), a clinical-stage immunotherapy and targeted oncology company, today announced financial results for the third quarter ended September 30, 2024, and recent corporate updates.

“With the Prescription Drug User Fee Act (“PDUFA”) goal date set for next month, we await the decision by the U.S. Food and Drug Administration (“FDA”) on our Biologics License Application (“BLA”) resubmission for cosibelimab, our anti-programmed death ligand-1 (“PD-L1”) antibody,” said James Oliviero, President and Chief Executive Officer of Checkpoint. “The $9.2 million in cash proceeds received this month from the exercise of existing warrants has strengthened our balance sheet to extend beyond our PDUFA date and into 2025. We are now fully focused on preparing for the potential approval of cosibelimab and look forward to potentially offering oncologists a new, differentiated treatment option for patients with advanced cutaneous squamous cell carcinoma (“cSCC”).”

Recent Corporate Updates:

• In July 2024, Checkpoint announced that the FDA accepted for review the resubmission of its BLA for cosibelimab as a complete response to the complete response letter (“CRL”) issued in December 2023 and set a PDUFA goal date of December 28, 2024.
• Also in July 2024, Checkpoint announced a collaboration to explore the combined therapeutic potential of cosibelimab, its anti-PD-L1 antibody with dual mechanism of action, with GC Cell’s Immuncell-LC, an innovative autologous Cytokine Induced Killer T cell therapy composed of cytotoxic T lymphocytes and natural killer T cells.
• Also in July 2024, Checkpoint completed a registered direct offering priced At-the-Market under Nasdaq rules and a concurrent private placement of warrants to purchase Checkpoint common stock, for total gross proceeds of approximately $12.0 million.
• In September 2024, Checkpoint presented longer-term data from its pivotal trial of cosibelimab in locally advanced and metastatic cSCC during the European Society for Medical Oncology (“ESMO”) Congress 2024. Longer-term results for cosibelimab presented at the ESMO Congress demonstrate a deepening of response over time, with higher objective response and complete response rates than initially observed at the primary analyses. A copy of the ESMO poster can be found on the Publications page of Checkpoint’s website.
• In November 2024, Checkpoint received $9.2 million in cash proceeds through the exercise of existing warrants.

Forward‐Looking Statements

This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended, that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements regarding our resubmission of our BLA for cosibelimab and review thereof, our belief that the BLA resubmission potentially addresses all the issues in the CRL, our belief about the comprehensive nature of our BLA resubmission and reaching alignment with the FDA on our cosibelimab BLA resubmission strategy, our ability to work with our third-party contract manufacturing organization (“CMO”) and the FDA to adequately address the issues raised in the CRL and execute on a pathway forward for the potential marketing approval of cosibelimab, the adequacy of the responses to the inspection issues submitted to FDA by our third-party CMO, our projections of regulatory review timelines, the commercial potential of cosibelimab, if approved, and the potential differentiation of cosibelimab, including a potentially favorable safety profile as compared to the currently available anti-programmed death receptor-1 therapies and the dual mechanism of action of cosibelimab translating into potential enhanced efficacy. Factors that could cause our actual results to differ materially include the following: the risks and uncertainties associated with the regulatory review process; uncertainties regarding the timeline of FDA review of the resubmitted BLA; any inability to successfully work with the FDA to find a satisfactory solution to address any concerns in a timely manner or at all during the review process for the BLA, including any inability to provide the FDA with data, analysis or other information sufficient to support an approval of the BLA; our, and our third party CMO’s, ability to adequately address the issues raised in the CRL; issues associated with any facility inspection or re-inspection of our third party CMO or otherwise during the review process for the BLA; the risk that our third-party CMO will not meet deadlines, and/or comply with applicable regulations; whether the FDA accepts the data and results as included in the BLA resubmission at levels consistent with the published results, or at all; our ability to execute a partnering or other relationship to enable the commercialization of cosibelimab, if approved, on acceptable terms, if at all; the risk that topline and interim data remains subject to audit and verification procedures that may result in the final data being materially different from the topline or interim data we previously published; the risk that safety issues or trends will be observed in the clinical trial when the full safety dataset is available and analyzed; the risk that a positive primary endpoint does not translate to all, or any, secondary endpoints being met; risks that regulatory authorities will not accept an application for approval of cosibelimab based on data from the Phase 1 clinical trial; the risk that the clinical results from the Phase 1 clinical trial will not support regulatory approval of cosibelimab to treat cSCC or, if approved, that cosibelimab will not be commercially successful; risks related to our chemistry, manufacturing and controls and contract manufacturing relationships; risks related to our ability to obtain, perform under and maintain financing and strategic agreements and relationships; risks related to our need for substantial additional funds; other uncertainties inherent in research and development; our dependence on third-party suppliers; government regulation; patent and intellectual property matters; competition; unfavorable market or other economic conditions; and our ability to achieve the milestones we project, including the risk that the evolving and unpredictable Russia/Ukraine conflict and COVID-19 pandemic delay achievement of those milestones. Further discussion about these and other risks and uncertainties can be found in our Quarterly Report on Form 10-Q for the period ended June 30, 2024, and in our subsequent other filings with the U.S. Securities and Exchange Commission.
