Checkpoint Therapeutics Announces Cosibelimab Longer-Term Results Demonstrating Substantial Increases in Complete Response Rates in Advanced Cutaneous Squamous Cell Carcinoma
WALTHAM, Mass., July 27, 2023 (GLOBE NEWSWIRE) -- Checkpoint Therapeutics, Inc. (“Checkpoint”) (Nasdaq: CKPT), a clinical-stage immunotherapy and targeted oncology company, today announced new, longer-term data for cosibelimab from its pivotal studies in locally advanced and metastatic cutaneous squamous cell carcinoma (“cSCC”). These results demonstrate a deepening of response over time, resulting in substantially higher complete response rates than previously reported. Furthermore, responses continue to remain durable over time with the median duration of response not yet reached in either group. Results determined by independent central review by treatment group were as follows:
- “We are excited to see the substantial increases in the rate of patients experiencing a complete response of their cSCC tumors with further cosibelimab treatment in both our locally advanced and metastatic pivotal trials,” said James Oliviero, President and Chief Executive Officer of Checkpoint.
- Mr. Oliviero continued, “Unlike PD-1 inhibitors, cosibelimab does not interrupt the body’s PD-1/PD-L2 pathway, which we believe results in cosibelimab’s low rates of autoimmunity.
- The application is filed and under review with a Prescription Drug User Fee Act (“PDUFA”) goal date of January 3, 2024.
- Checkpoint plans to present these updated results at an upcoming medical conference.
