Checkpoint Therapeutics Reports First Quarter 2022 Financial Results and Recent Corporate Highlights

WALTHAM, Mass., May 12, 2022 (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, 2022 and recent corporate highlights.

James F. Oliviero, President and Chief Executive Officer of Checkpoint, said, “The positive topline results generated in the first quarter from our ongoing registrational trial of cosibelimab in metastatic cutaneous squamous cell carcinoma (“cSCC”) laid the foundation for a potentially transformational year for our lead immunotherapy product candidate and for our company as a whole. We remain on track to submit our U.S. Biologics License Application (“BLA”) for cosibelimab later this year and continue to evaluate partnership opportunities for the potential commercialization of cosibelimab in Europe and other key territories worldwide.” Mr. Oliviero continued, “Our focus remains on advancing our pipeline of potentially life-saving novel oncology therapies with the goal of expanding patient access globally through a disruptive pricing strategy, beginning with the $30 billion and growing PD-(L)1 market.”

Recent Corporate Highlights:

• In January 2022, Checkpoint announced positive topline results from the ongoing registration-enabling clinical trial evaluating the safety and efficacy of its anti-PD-L1 antibody, cosibelimab, administered as a fixed dose of 800 mg every two weeks in patients with metastatic cSCC. The study met its primary endpoint, with cosibelimab demonstrating a confirmed objective response rate of 47.4% (95% CI: 36.0, 59.1) based on independent central review of 78 patients enrolled in the metastatic cSCC cohort using Response Evaluation Criteria in Solid Tumors version 1.1 criteria. Checkpoint intends to submit a BLA for cosibelimab in late 2022, followed by a Marketing Authorization Application submission in Europe and other territories worldwide. With a potentially favorable safety profile versus anti-PD-1 therapy and a plan to commercialize at a substantially lower price, Checkpoint believes cosibelimab has the potential to be a market disruptive product in the $30 billion and growing PD-(L)1 class.
• In April 2022, Checkpoint announced that the results of its pivotal trial of cosibelimab in cSCC were selected for poster presentation at the 2022 American Society of Clinical Oncology Annual Meeting, to be held at McCormick Place, in Chicago, June 3-7, 2022.

Financial Results:

• Cash Position: As of March 31, 2022, Checkpoint’s cash and cash equivalents totaled $41.5 million, compared to $54.7 million at December 31, 2021, a decrease of $13.2 million.
• R&D Expenses: Research and development expenses for the first quarter of 2022 were $14.7 million, compared to $4.2 million for the first quarter of 2021, an increase of $10.5 million. Research and development expenses for the first quarters of 2022 and 2021 each included $0.2 million of non-cash stock expenses.
• G&A Expenses: General and administrative expenses for the first quarter of 2022 were $2.2 million, compared to $2.4 million for the first quarter of 2021, a decrease of $0.2 million.

Net loss for the first quarter of 2022 included $0.9 million of non-cash stock expenses, compared to $1.4 million for the first quarter of 2021.

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 relating to the potential differentiation of cosibelimab, including a potentially favorable safety profile as compared to the currently available anti-PD-1 therapies, the two-fold mechanism of action of cosibelimab translating into potential enhanced efficacy, and projections of publication and regulatory submission timelines. Factors that could cause our actual results to differ materially include the following: our ability to successfully deliver the complete dataset from the clinical trial and complete a BLA submission on schedule as planned; the risk that topline data remains subject to audit and verification procedures that may result in the final data being materially different from the topline 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 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; 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 for the fiscal year ended December 31, 2021 and in our other filings with the U.S. Securities and Exchange Commission.
