What This Trial Is Studying

The purpose of this study is to assess the efficacy and safety of opevesostat plus hormone replacement therapy (HRT) compared to alternative abiraterone acetate or enzalutamide in participants with Metastatic Castration-resistant Prostate Cancer (mCRPC) previously treated with one next-generation hormonal agent (NHA). The primary study hypothesis is that opevesostat is superior to alternative abiraterone acetate or enzalutamide with respect to radiographic progression free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1), as assessed by Blinded Independent Central Review (BICR), in androgen…

Eligibility Snapshot
  • : The main inclusion criteria include but are not limited to the following: * Have histologically or cytologically confirmed adenocarcinoma of the prostate without small cell histology * Has prostate cancer progression while receiving androgen deprivation therapy (ADT) (or post bilateral orchiectomy) within 6 months before screening * Has current evidence of distant metastatic disease (M1 disease) documented by either bone lesions on bone scan and/or soft tissue disease shown by computed tomography (CT)/magnetic resonance imaging (MRI) * Has disease that progressed during or after treatment with one next-generation hormonal agent (NHA) for hormone sensitive prostate cancer (HSPC) (metastatic hormone-sensitive prostate cancer [mHSPC] or non-metastatic hormone-sensitive prostate cancer [nmHSPC]), or castration-resistant prostate cancer (CRPC) (metastatic castration-resistant prostate cancer [mCRPC] or non-metastatic castration-resistant prostate cancer [nmCRPC]), for at least 8 weeks of NHA treatment (at least 14 weeks of NHA treatment for participants with bone progression). Note: Participants may have received abiraterone acetate and docetaxel or darolutamide and docetaxel for HSPC. However, participants must have received no more than 6 cycles of docetaxel and had no radiographic disease progression while receiving docetaxel * Has had prior treatment with poly (ADP-ribose) polymerase inhibitor (PARPi) or were deemed ineligible to receive treatment…
