About this study

This is a phase 3, randomized, open-label study of opevesostat compared to alternative abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer (mCRPC) with respect to overall survival (OS) in participants with mCRPC previously treated with next-generation hormonal agent (NHA) and taxane-based chemotherapy. It is hypothesized that opevesostat is superior with respect to OS in androgen receptor ligand binding domain (AR LBD) mutation-negative and -positive participants.
