Cogent Biosciences Inc. is eyeing an NDA submission to the U.S. FDA by the end of this year in the wake of positive top-line results from the registration-directed second part of the Summit phase II trial testing bezuclastinib in non-advanced systemic mastocytosis (SM). The data show clinically meaningful and highly statistically significant improvements in SM across the primary and all key secondary endpoints, including patient-reported symptoms and objective measures of mast cell burden.
