Time frame: From randomization until radiographic progression at any time, or death within 112 days of treatment discontinuation, whichever occurred first (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
MFS:time from randomization to first date of radiographic progression (RP) (by Blinded independent central radiology review [BICR]) at any time or death within 112 days of treatment discontinuation without evidence of RP.RP for bone disease:appearance of 1 or more metastatic lesions on bone scan.RP for soft tissue disease:per Response Evaluation Criteria in Solid Tumors,[RECIST 1.1])-at least a 20 percent (%) increase in the sum of diameters of target lesions,taking as reference the smallest sum on study (includes the baseline sum if smallest on study).Participants who did not have MFS event at the time of analysis data cut-off (28 June 2017) were censored at date of last assessment showing no objective evidence of RP prior to skeletal-related event or two or more consecutive missed tumor assessments. Participants who were randomized but later confirmed to have metastatic disease before randomization were censored on date of randomization. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization until first PSA progression (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
Time to PSA progression was defined as the time from randomization to the date of first PSA value demonstrating progression, which was subsequently confirmed. For participants with PSA decline at Week 17, PSA progression was defined according to Prostate Cancer Working Group 2 (PCWG2) guidelines as the date that a 25% or greater increase and an absolute increase of 2 nanograms per milliliter (ng/mL) above the nadir (or baseline for participants with no PSA decline by Week 17) was documented, which was confirmed by a second consecutive value obtained at least 3 weeks or later. Participants without confirmed PSA progression at the time of analysis were right censored at the date of last PSA assessment before the analysis data cut-off date for the purposes of analysis. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization until first use of new antineoplastic therapy(until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
Time to first use of new antineoplastic therapy was defined as the time from randomization to first use of new antineoplastic for prostate cancer. Participants not starting treatment with a new antineoplastic therapy at the time of analysis were right censored at the date of last assessment before the analysis data cutoff date for the purposes of analysis. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization until death (up to a maximum of 68.8 months)
Overall survival (OS) was defined as the time (in months) from randomization to death from any cause. For participants who were alive at the time of the analysis data cutoff, OS time was censored at the last date the participant was known to be alive or analysis data cutoff date, whichever was earlier. Participants with no post baseline survival information were censored on the date of randomization. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization until onset of pain progression (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
Pain was assessed using the score from the Brief Pain Inventory-Short Form (BPI-SF) question 3: "Please rate your pain by marking the box beside the number that best describes your pain at its worst in the last 24 hours." Time to this event was defined as the time from randomization to onset of pain progression, where pain progression was defined as a 2-point or more increase from baseline in the question 3 score. Participants without observed pain progression at the time of analysis were right censored at the date of last pain assessment for the purposes of analysis. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization up to the first use of cytotoxic chemotherapy (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
Time to first use of cytotoxic chemotherapy was defined as the time from randomization to the first use of cytotoxic chemotherapy for prostate cancer. Participants not starting treatment with a cytotoxic chemotherapy for prostate cancer at the time of analysis were right censored at the date of last assessment before the analysis data cutoff date for the purposes of analysis. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization up to first use of cytotoxic chemotherapy for prostate cancer or death due to prostate cancer (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
Chemotherapy-free disease-specific survival was defined as the time from randomization to first use of cytotoxic chemotherapy for prostate cancer or death due to prostate cancer as assessed by the investigator. Participants not starting treatment with a cytotoxic chemotherapy or not known to have died due to prostate cancer at the time of analysis were right censored at the date of last assessment before the analysis data cutoff date for the purposes of analysis. Analysis was based on Kaplan-Meier estimates.
Time frame: From randomization up to first use of cytotoxic chemotherapy for prostate cancer or death due to any cause (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)

Time frame: From randomization until first PSA progression (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
PSA response was calculated at each visit as a decline from baseline in PSA (ng/mL) to the maximal PSA response with thresholds at 50% and 90%. Additionally, PSA response was assessed as a decline to undetectable levels, where undetectable level was defined as below the limit of quantification of the centrally assessed PSA results (the lower limit of quantification was 0.02 ng/mL). PSA response was confirmed by a second consecutive value at least 3 weeks later.

Time frame: From first dose of study drug to the last dose + 30 days (or the day before initiation of a new antineoplastic treatment, whichever occurred first) (until the data cut-off date of 28 June 2017, maximum duration of treatment: 42.8 months)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. A treatment-emergent AE (TEAE) was defined as an AE that occurred from the date and time of the first dose of study drug through the date of last dose +30 days (or the day before initiation of a new antineoplastic treatment, whichever occurred first). AEs included both non-serious adverse events (AEs) and SAEs.
