Primary Endpoints (CT.gov)

Time to Prostate Specific Antigen (PSA) Progression (TTPP) Based on Prostate Cancer Working Group 2 (PCWG2) Criteria

Time frame: From randomization until first documented PSA progression (up to 3 years 3 months)

Secondary Endpoints

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)

Number of Participants With Grade 3 or Higher Abnormalities in Laboratory Values

Percentage of Participants Who Achieved Prostate Specific Antigen (PSA) Response (>=50% PSA Reduction)

Eligibility Criteria

Inclusion Criteria: * Histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features, with high risk for development of metastases, defined as prostate-specific antigen doubling time (PSADT) less than or equals to (\<=) 10 months. PSADT is calculated using at least 3 prostate-specific antigen (PSA) values obtained during continuous androgen deprivation therapy (ADT) * Castration-resistant prostate cancer (PC) demonstrated during continuous ADT, defined as 3 PSA rises at least 1 week apart, with the last PSA greater than (\>) 2 nanogram per milliliter (ng/mL) * Surgically or medically castrated, with testosterone levels of less than (\<) 50 nanogram per deciliter (ng/dL). If the participant is medically castrated, continuous dosing with gonadotropin releasing hormone analog (GnRHa) must have been initiated at least 4 weeks prior to randomization and must be continued throughout the study to maintain castrate levels
