Checkpoint Therapeutics Reports First Quarter 2024 Financial Results and Recent Corporate Updates

WALTHAM, Mass., May 10, 2024 (GLOBE NEWSWIRE) — Checkpoint Therapeutics, Inc. (“Checkpoint”) (Nasdaq: CKPT), a clinical-stage immunotherapy and targeted oncology company, today announced financial results for the first quarter ended March 31, 2024, and recent corporate updates.

James F. Oliviero, President and Chief Executive Officer of Checkpoint, said, “Over the past few months, we have worked closely with our third-party contract manufacturing organization (“CMO”) for cosibelimab to resolve their inspection deficiencies noted in the complete response letter (“CRL”) we received from the U.S. Food and Drug Administration (“FDA”) last December. Recently, our CMO submitted to FDA their response to the inspection deficiencies, which we believe could allow for the resubmission of our biologics license application (“BLA”). We plan to meet with the FDA shortly, at which time we will seek to reach alignment for a potential mid-year BLA resubmission.”

Recent Corporate Updates:

• Checkpoint submitted a BLA to the FDA in January 2023 seeking approval of cosibelimab as a potential new treatment for patients with metastatic or locally advanced cutaneous squamous cell carcinoma (“cSCC”) who are not candidates for curative surgery or curative radiation, and the FDA accepted the BLA for filing in March 2023. In December 2023, the FDA issued a CRL for the cosibelimab BLA. The CRL only cited findings that arose during a multi-sponsor inspection of Checkpoint’s third-party CMO as approvability issues to address in a BLA resubmission. The CRL did not state any concerns about the clinical data package, safety, or labeling for the approvability of cosibelimab. Checkpoint intends to seek to address the feedback in a potential BLA resubmission, which is currently targeted for mid-year.
• In January 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 $14.0 million.
• In March 2024, Checkpoint announced the appointment of life sciences executive, Amit Sharma, M.D., FACP, FASN, FNKF, currently Vice President of Clinical Development and Therapeutic Head for Nephrology and Hematology at Alexion, AstraZeneca Rare Disease, as a non-executive director to Checkpoint’s Board of Directors.

Financial Results:

• Cash Position: As of March 31, 2024, Checkpoint’s cash and cash equivalents totaled $11.2 million, compared to $4.9 million at December 31, 2023, an increase of $6.3 million.
• R&D Expenses: Research and development expenses for the first quarter of 2024 were $8.5 million, compared to $15.8 million for the first quarter of 2023, a decrease of $7.3 million. Research and development expenses for the first quarter of 2024 included $0.5 million of non-cash stock expenses, compared to $0.4 million for the first quarter of 2023.
• G&A Expenses: General and administrative expenses for the first quarter of 2024 were $2.5 million, compared to $2.3 million for the first quarter of 2023, an increase of $0.2 million. General and administrative expenses for the first quarter of 2024 included $0.6 million of non-cash stock expenses, compared to $0.7 million for the first quarter of 2023.
• Net Loss: Net loss attributable to common stockholders for the first quarter of 2024 was $10.9 million, or $0.33 per share, compared to a net loss of $10.5 million, or $0.89 per share, in the first quarter of 2023. Net loss for the first quarter of 2024 and 2023 both included $1.1 million of non-cash stock expenses.

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 ability to work with our third-party CMO and the U.S. FDA to adequately address the issues raised in the CRL and execute on a pathway forward for the potential approval of cosibelimab for the treatment of patients with metastatic or locally advanced cSCC who are not candidates for curative surgery or radiation, the adequacy of the responses to the inspection issues submitted to FDA by our CMO to allow a BLA resubmission, and our projections of resubmission and regulatory review timelines, statements related to our ability to shorten our launch timeline in anticipation of a potential approval, and statements relating to the potential differentiation of cosibelimab, including a potentially favorable safety profile as compared to the currently available anti-PD-1 therapies and the two-fold mechanism of action of cosibelimab translating into potential enhanced efficacy. Factors that could cause our actual results to differ materially include the following: 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 Annual Report on Form 10-K, and in our other filings with the U.S. Securities and Exchange Commission.
