Arm 1: Ipilimumab 3 mg/kgIpilimumabIpilimumab 3 mg/kg injection intravenously every 3 weeks for 4 doses in Induction phase. Subjects that are eligible to receive Ipilimumab in the Maintenance phase will be dosed every 12 weeks for a maximum of 3 years since the first induction dose
Arm 2: Ipilimumab 10 mg/kgIpilimumabIpilimumab 10 mg/kg injection intravenously every 3 weeks for 4 doses in Induction phase. Subjects that are eligible to receive Ipilimumab in the Maintenance phase will be dosed every 12 weeks for a maximum of 3 years since the first induction dose
Primary Outcome Measures
NameTimeMethod
Radiographic Progression-free Survival (rPFS)From date of randomization until disease progression or death (assessed up to December 2016, approximately 24 months)

rPFS was defined as the time from the date of randomization until the date of disease progression based on radiographic evidence and/or death from any cause, whichever occurs first. Radiographic disease progression is defined as: Confirmed bone disease progression according to criteria adapted from the Prostate Cancer Clinical Trials Working Group 2 (PCWG2), OR Non-bone disease progression according to the modified Response Evaluation Criteria In Solid Tumors (RECIST) 1.1. After termination of the study, collection of tumor assessments and other data to support the efficacy analyses was no longer required in patients who discontinued study treatment. As a result, the presented efficacy results are based on limited data. The number of participants with reported radiographic progression is shown.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)From randomization to death from any cause (assessed up to December 2016, approximately 24 months)

OS was defined as the time from the date of randomization until the date of death. For those participants who have not died, OS was censored at the last date the participant was known to be alive. After termination of the study, collection of tumor assessments and other data to support the efficacy analyses was no longer required in patients who discontinued study treatment. As a result, the presented efficacy results are based on limited data. The total number of reported deaths is shown.

Prostate Specific Antigen Progression-free Survival (PSA PFS)From randomization to the earliest date of PSA progression or death, whichever comes earlier (assessed up to December 2016, approximately 24 months)

Prostate specific antigen progression-free survival (PSA PFS) was defined as the time from randomization to the earliest date of PSA progression or death, whichever occurs earlier. Participants who did not progress or die were censored at the last PSA assessment date. After termination of the study, collection of tumor assessments and other data to support the efficacy analyses was no longer required in patients who discontinued study treatment. As a result, the presented efficacy results are based on limited data. The number of participants with reported PSA progression is shown.

Number of Participants Who Experienced Immune-related Adverse Events (irAEs)From first dose of ipilimumab to last dose plus 90 days

The total number of participants with immune-related adverse events of any grade is reported for each arm.

Time to Pain ProgressionFrom randomization until pain progression (assessed up to December 2016, approximately 24 months)

Pain progression was defined as an increase in BPI-SF pain Item #3 score of \>= 2 point from baseline maintained over 2 consecutive periods. After termination of the study, collection of tumor assessments and other data to support the efficacy analyses was no longer required in patients who discontinued study treatment, and presented efficacy results are based on limited data. The number of participants with reported pain progression is shown.

Prostate Specific Antigen Response RateFrom baseline to PSA response (assessed up to December 2016, approximately 48 months)

PSA response rate was defined as the proportion of participants with a 50% or greater decrease from baseline to the lowest post-baseline PSA result (confirmed 3 weeks later) for each randomized arm. After termination of the study, collection of tumor assessments and other data to support the efficacy analyses was no longer required in patients who discontinued study treatment. As a result, the presented efficacy results are based on limited data. The number of participants showing PSA response is shown.
