COGT’s NDA for Bezuclastinib Based on SUMMIT Study

The above-mentioned NDA for bezuclastinib was based on data from the pivotal SUMMIT study.

The SUMMIT study achieved the primary and all key secondary endpoints, demonstrating clinically meaningful and highly statistically significant improvements following treatment with bezuclastinib in non-advanced SM patients.

Data from the SUMMIT study showed steadily deepening symptom improvement, suggesting lasting benefits following longer treatment with bezuclastinib. Patients who were treated with bezuclastinib did not just improve early on, but their symptoms kept getting better over time.

Treatment with bezuclastinib showed a favorable safety and tolerability profile, supporting its potential for chronic use in NonAdvSM, across the SUMMIT study.

COGT’s Other Development Activities With Bezuclastinib

The company is also evaluating bezuclastinib for another SM indication in a separate phase III study.

SM is a rare hematological disease impacting the immune system with debilitating symptoms that take a serious toll on the physical and psychological quality of life of patients.

The pivotal phase III APEX study is evaluating bezuclastinib for treating patients with advanced SM. The NDA for bezuclastinib in advanced SM is expected to be submitted in the first half of 2026.

Besides the SM indication, Cogent Biosciences is also developing bezuclastinib in combination with sunitinib for treating patients with gastrointestinal stromal tumors (“GIST”) who have received prior treatment with imatinib in the phase III PEAK study.

The NDA filing for the bezuclastinib combo for treating patients with second-line GIST is expected to be completed in April next month.

A potential approval for bezuclastinib is likely to give Cogent Biosciences the first commercial product and help it generate meaningful revenues.
