Sponsor: Bristol-Myers Squibb

Phase: Phase 3

Eligibility:

• Age: minimum 18 Years maximum N/A
• Gender: Male

Inclusion Criteria:

• Histologic confirmation of adenocarcinoma of the prostate without small cell features
• Current evidence of metastatic disease documented by either bone lesions on radionuclide bone scan and/or soft tissue lesions on computerized tomography/magnetic resonance imaging (CT/MRI)
• Eastern Cooperative Oncology Group (ECOG) performance status 0-1
• Ongoing androgen deprivation therapy (ADT) with a gonadotropin-releasing hormone (GnRH) analogue or bilateral orchiectomy
• Documented prostate cancer progression per Prostate Cancer Working Group (PCWG3) criteria within 6 months prior to screening
• Chemotherapy-naïve for metastatic castration-resistant prostate cancer (mCRPC), with 1 to 2 prior second generation hormonal therapies in the recurrent non-metastatic setting and/or metastatic setting, and no more than 1 second generation hormonal therapy in the mCRPC setting. Must have progressed during or after second generation hormonal therapy or have documented intolerance to second generation hormonal therapy
• Participants must meet one of the following criteria regarding tissue submission: Sufficient tumor samples from a newly obtained ("fresh") biopsy (obtained during screening); or archival tumor tissue in the form of formalin-fixed paraffin-embedded (FFPE) block or unstained tumor tissue slides. For participants with bone-only disease or inaccessible soft tissue lesions or if the biopsy procedure would pose an unacceptable clinical risk for the participant, submission of tumor tissue obtained from a fresh biopsy is not required.

• Prior treatment with docetaxel or other chemotherapy for mCRPC. Prior docetaxel for metastatic castration-sensitive prostate cancer is permitted if at least 12 months have elapsed from last dose of docetaxel Other protocol-defined inclusion/
