Primary Outcome Measures :
  1. Overall Survival [ Time Frame: Baseline until death (approximately up to 4.5 years) ]
    Overall survival was calculated from the date of participant randomization to the date of participant death due to any cause. Participants without documentation of death at time of the analysis were censored as of the date the participant was last known to be alive, or the data cutoff date, whichever was earlier.

    Time to PSA progression was defined as time from randomization to a PSA increase of 25% and PSA rise of at least 2 nanogram per milliliter (ng/mL) above the lowest value observed post baseline or, if no PSA decline occurred post baseline, above the baseline PSA.

  16. Number of Participants With Shifts From Baseline Between Favorable and Unfavorable Categories in Circulating Tumor Cell Count (CTC) [ Time Frame: Baseline and EOT (Cycle 59 Day 58) ]
    A favorable CTC count was defined as less than (<) 5 counts per (/) 7.5 mililiter (mL) in whole blood. An unfavorable CTC count was defined as >=5 counts/7.5 mL in whole blood.

    Percentage of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST 1.1. The overall objective response was defined as a complete response (CR) or partial response (PR). A complete response (CR) was defined as the disappearance of all target lesions determined by computerized tomography (CT) or MRI. Any pathological lymph nodes (whether target or non-target) must have had reduction in short axis to <10 millimetre (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.

  19. Time to Pain Response [ Time Frame: Baseline until disease progression or death, whichever occurred first (approximately up to 4.5 years) ]
    Time to pain response was defined as the time from randomization until first pain response. Pain response was defined as the occurrence of 1 of the following and confirmed by an additional assessment, at least 3 weeks but not more than 5 weeks later: A >= 2 point reduction from baseline in BPI-SF worst pain score without an increase in analgesic use, or a 25% or more reduction in analgesic use from baseline without an increase in worst pain score from baseline. The analysis was performed by Kaplan-Meier method.

  20. Number of Participants With Best Pain Response [ Time Frame: Baseline until disease progression or death, whichever occurred first (approximately up to 4.5 years) ]
    Best pain response was evaluated in participants who had a pain response across the entire study were summarized by treatment group. The pain response was defined as a >=2-point reduction from baseline in BPI-SF worst pain score without an increase in analgesic use, or a 25% or more reduction in analgesic use from baseline without an increase in worst pain score from baseline.

  21. Percentage of Participants With Health-related Quality of Life (HRQOL) Response at Week 12 [ Time Frame: Week 12 ]
    The global health status or quality of life (QOL) was measured as the HRQOL response rate at 12 weeks using the 2-item global health status index of the european organization for research and treatment of cancer-quality of life questionnaire-C30 (EORTC QLQ-C30) instrument. HRQOL response was defined as a 17-point increase from the baseline assessment on the QOL index, after the score had been linearly transformed to a 0 to 100 scale. EORTC QLQ-C30: included 5 functional scales (physical, role, cognitive, emotional, and social), 1 global health status, 3 symptom scales (fatigue, pain, nausea/vomiting) and 6 single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea and financial difficulties). Most questions used 4 point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score representing better level of functioning or greater degree of symptoms.
