A Phase 3 Randomized, Open-label Study of MK-5684 Versus Alternative Abiraterone Acetate or Enzalutamide in Participants With Metastatic Castration-resistant Prostate Cancer (mCRPC) Previously Treated With Next-generation Hormonal Agent (NHA) and Taxane-based Chemotherapy
This trial is testing MK-5684 in men with metastatic castration-resistant prostate cancer (mCRPC) previously treated with next-generation Hormonal Agent (NHA) and Taxane-based chemotherapy. This trial will compare MK-5684 to abiraterone acetate and enzalutamide. Abiraterone acetate and enzalutamide are standard treatments for mCRPC. The purpose of this trial is to test the safety of the trial drug, MK-5684, see how well the drug works, and see how the body handles the drug. We also want to see if participants who get MK-5684 live longer compared to those who get abiraterone acetate or enzalutamide.
