Researchers are evaluating the effectiveness and safety of the drug BMS-986365 compared to the investigator's choice of therapy in men with metastatic castration-resistant prostate cancer. This Phase 3 study aims to measure the length of time participants live without radiographic disease progression, using established criteria for bone and soft tissue cancer progression. The study focuses on patients who have already been treated with androgen receptor pathway inhibitors and have metastatic prostate cancer confirmed by imaging. Participants will be randomly assigned to receive either one of two dose levels of BMS-986365 or the investigator's choice of treatment, which may include Docetaxel plus Prednisone/Prednisolone, Abiraterone plus Prednisone/Prednisolone, or Enzalutamide. The study has two parts: initially, participants are assigned to one of three groups including two BMS-986365 doses or comparator therapy, followed by a second part where they are randomized to either the selected BMS-986365 dose or the comparator treatment. During the study, participants will be monitored for disease progression through scans and evaluations using Response Evaluation Criteria in Solid Tumors and Prostate Cancer Clinical Trials Working Group criteria, with follow-up lasting up to four years. Safety and treatment effects will be assessed regularly, and participants' symptoms and quality of life will be closely observed. This long-term follow-up helps researchers understand the treatment's impact on cancer progression and patient well-being.
