“The receipt of Fast Track designation for ONCT-534 supports our belief that patients with mCRPC who relapse after treatment with ARPIs such as enzalutamide or abiraterone, represent an important unmet medical need,” said James Breitmeyer, M.D., Ph.D., Oncternal’s President and CEO. “We believe that due to ONCT-534’s novel mechanism of action, it may address important androgen receptor (AR) escape mechanisms that result in resistance to currently approved ARPIs. We look forward to working with FDA, investigators, and industry collaborators to bring ONCT-534 to patients as quickly as possible.”
