Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryRadiographic Progression-Free Survival (PFS)Up to 44 months
Radiographic PFS was defined as the time (in months) interval from randomization to the first date of radiographic progression or death. Radiographic progression included progression by bone scan (according to modified Prostate Cancer Working Group 2 \[PCWG2\] criteria), defined as at least 2 new lesions on bone scan and progression of soft tissue lesions by computed tomography (CT) or magnetic resonance imaging (MRI) (according to Response Evaluation Criteria in Solid Tumors \[RECIST\] 1.1 criteria). As per the RECIST 1.1 guideline, progression requires a 20 percent (%) increase in the sum of diameters of all target lesions and a minimum absolute increase of 5 millimeter (mm) in the sum as compared to nadir sum of diameter.
PrimaryOverall Survival (OS)Up to 66 monthsOverall survival was defined as the time from randomization to date of death from any cause.
SecondaryTime to Initiation of ChemotherapyUp to 66 monthsTime to initiation of chemotherapy was defined as the time (in months) interval from the date of randomization to the date of initiation of cytotoxic chemotherapy for prostate cancer.
SecondaryTime to Subsequent Therapy for Prostate CancerUp to 66 monthsTime to subsequent therapy was defined as the time (in months) interval from the date of randomization to the date of initiation of subsequent therapy for prostate cancer.
SecondaryTime to Pain ProgressionUp to 66 months
Time to pain progression was defined as the time (in months) interval from randomization to the first date a participant experienced a greater than or equal to (\>=) 30 percent (%) increase in Brief Pain Inventory-Short Form (BPI-SF) from baseline in the BPI-SF worst pain intensity (Item 3) observed at 2 consecutive evaluations (\>=4) weeks apart. BPI-SF was an 11-item questionnaire, designed to assess severity and impact of pain on daily functions. Total score ranged from 0 to 10 with 0 representing "no pain" and 10 representing" pain as bad as you can imagine.
SecondaryTime to Skeletal-Related EventUp to 66 monthsTime to skeletal-related event was defined as the earliest of the following: clinical or pathological fracture, spinal cord compression, palliative radiation to bone, or surgery to bone.
SecondaryTime to Prostate-Specific Antigen (PSA) ProgressionUp to 66 months
Time to PSA progression was defined as the time (in months) interval from the date of randomization to the date of PSA progression, according to PCWG2 criteria. PCWG2 defines PSA progression as the date that a 25 percent (%) or greater increase and an absolute increase of 2 nanogram per milliliter (ng/mL) or more from the nadir is documented, which is confirmed by a second value obtained 3 or more weeks later.
