A Study of Talazoparib in Men With DNA Repair Defects and Metastatic Castration-Resistant Prostate Cancer

Summary

The purpose of this international, phase 2, open-label, response rate study of talazoparib is to assess the efficacy and safety of talazoparib in men with DNA repair defects metastatic castration-resistant prostate cancer (CRPC) who previously received taxane-based chemotherapy and progressed on at least 1 novel hormonal agent (enzalutamide and/or abiraterone acetate/prednisone).
