Eligibility Criteria

Inclusion Criteria: * Adenocarcinoma of the prostate * Metastatic disease as documented by technetium-99m (99mTc) bone scan or metastatic lesions by computed tomography (CT) or magnetic resonance imaging (MRI) scans (visceral or lymph node disease). If lymph node metastasis is the only evidence of metastasis, it must be greater than or equal to (\>=) 2 centimeter (cm) in the longest diameter * Castration-resistant prostate cancer demonstrated during continuous androgen deprivation therapy (ADT), defined as 3 rises of PSA, at least 1 week apart with the last androgen deprivation therapy (PSA) \>= 2 nanogram per milliliters (ng/mL) * Participants who received a first generation anti-androgen (eg, bicalutamide, flutamide, nilutamide) must have at least a 6-week washout prior to randomization and must show continuing disease (PSA) progression (an increase in PSA) after the washout period * Prostate cancer progression documented by prostate-specific antigen (PSA) according to the Prostate
