You may be eligible if
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 of testosterone
Participants who received a first-generation anti-androgen (example: bicalutamide, flutamide, nilutamide) must have at least a 4-week washout prior to randomization and must show continuing disease progression (an increase in PSA) after washout
At least 4 weeks must have elapsed from major surgery or radiation therapy prior to randomization
You may not be if
Presence of distant metastases, including central nervous system (CNS) and vertebral or meningeal involvement, or history of distant metastases. Exception: Pelvic lymph nodes \<2 centimeter in short axis (N1) located below the iliac bifurcation are allowed
Symptomatic loco-regional disease requiring medical intervention, such as moderate or severe urinary obstruction or hydronephrosis, due to primary tumor (example, tumor obstruction of bladder trigone)
Prior treatment with cytochrome P450 17 alpha-hydroxylase/17,20-lyase (CYP17) inhibitors (example: abiraterone acetate, orteronel, galerterone, ketoconazole, aminoglutethimide) for PC
Prior chemotherapy for PC, except if administered in the adjuvant/neoadjuvant setting
Prior treatment with second generation anti-androgens (example, enzalutamide)
History of seizure or condition that may pre-dispose to seizure (example: prior stroke within 1 year prior to randomization, brain arteriovenous malformation, schwannoma, meningioma, or other benign CNS or meningeal disease which may require treatment with surgery or radiation therapy)
