Checkpoint Resubmits Cosibelimab BLA
Checkpoint Therapeutics says it has completed the resubmission of its BLA to FDA for cosibelimab, an anti-programmed death ligand-1 antibody as a potential new treatment for patients with metastatic or locally advanced cutaneous squamous cell carcinoma who are not candidates for curative surgery or radiation. A company statement says the resubmission follows an agreement reached with FDA on a strategy to potentially address all approvability deficiencies outlined in a 12/2023 complete response letter. The company says the letter only cited findings that arose during a multi-sponsor inspection of Checkpoint’s third-party contract manufacturing organization and did not state any concerns about the clinical data package, safety, or labeling for the approvability of cosibelimab.
