Who We Are:
Cogent Biosciences is a publicly traded biotechnology company focused on developing novel precision therapies to treat a broad range of patients with unmet medical needs. Cogent’s lead program, bezuclastinib, is designed to selectively and potently inhibit exon 17 mutations found within the KIT receptor tyrosine kinase, including KIT D816V.
