Primary	Phase 2: Percentage of Participants With Prostate-specific Antigen (PSA) Response of 30 Percent (%), 50%, and 90%	PSA response rates (PSA-30, PSA-50, and PSA-90) were defined as greater than or equal to (>=) 30%, 50%, and 90% reductions, respectively, from baseline in PSA concentration.

Secondary	Phase 2: Time to PSA Progression	Time to PSA progression was defined as (date of PSA progression) - (date of first dose of drug) + 1, where PSA progression was defined as: For participants whose PSA concentrations never declined before the end of Cycle 4 of treatment: a) >=25% increase over the baseline level and an increase in absolute PSA concentration >=2 ng/mL; For participants who initially experienced a PSA decline: a) >=25% increase in PSA above the nadir concentration and an increase in absolute PSA concentration >=2 ng/mL.

A CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have had reduction in short axis to less than (<)10 millimeter (mm). A PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of longest diameters of non-lymph node lesions and of the short diameter(s) or short axis of lymph nodes.	Baseline until disease progression or death, whichever occurred first (up to approximately 25.4 months)
Secondary	Phase 2: Change From Baseline in Circulating Tumor Cells (CTCs)	Baseline is defined as the last scheduled observed measurement prior to the first dose of drug.
