About this trial
The purpose of this study is to compare the efficacy and safety of BMS-986365 versus the investigator's choice of therapy in participants with Metastatic Castration-resistant Prostate Cancer.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participants must have histologic or cytologic confirmation of adenocarcinoma of the prostate without small cell or neuro-endocrine features.
Participants must have current evidence of metastatic disease documented by either bone lesions on radionuclide bone scan and/or soft tissue lesions on computed tomography/magnetic resonance imaging (CT/MRI).
Participants must be asymptomatic or mildly symptomatic from prostate cancer with score on Brief Pain Inventory - Short Form (BPI-SF) that must be < 4.
Participants must have had previous treatment with an androgen receptor pathway inhibitor (abiraterone, enzalutamide, apalutamide, or darolutamide).
Disqualifiers
Participants must not have impaired cardiac function or clinically significant cardiac disease.
Participants must not have any brain metastasis.
Participants must not have any liver metastasis.
Participants with superscan on technetium-99m (Tc-99m) radionuclide bone scans.
