  Baseline Characteristics


  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Overall Survival: Time From Randomization to Date of Death   [ Time Frame: From randomization to death or date of last contact (maximum reached: 45 months) ]

2.  Secondary:   Percentage of Participants With an Objective Tumor Response by Modified Response Evaluation Criteria in Solid Tumors (RECIST)   [ Time Frame: At baseline and every 12 weeks thereafter to end of treatment, at end of treatment, and at follow-up (within 42 days of end of dosing) ]

3.  Secondary:   Time to First Skeletal-related Event (SRE)   [ Time Frame: From day of randomization to date of first SRE or to last SRE assessment, if subsequent cancer therapy begun or no SRE (maximum reached: 42 months) ]

4.  Secondary:   Percentage of Participants With A Reduction in Urinary N-telopeptide (uNTx) Level From Baseline   [ Time Frame: At baseline, prior to each docetaxel infusion (every 3 weeks) to end of treatment, at end of treatment, and at follow-up (within 14 days of end of dosing) ]

5.  Secondary:   Progression-free Survival (PFS)   [ Time Frame: From day of randomization to disease progression or death (or to last clinical assessment, if subsequent cancer therapy started or no progression or death) (maximum reached: approximately 43 months) ]

6.  Secondary:   Time to Prostate Specific Antigen (PSA) Progression   [ Time Frame: From randomization to date of first PSA measurement leading to confirmed PSA progression (or to last bone scan assessment, if no progression or if cancer therapy started) (maximum reached: 30 months) ]

7.  Secondary:   Percentage of Participants With a Reduction in Pain Intensity From Baseline   [ Time Frame: At baseline, prior to each docetaxel infusion (every 3 weeks), at end of treatment, and at follow-up (within 14 days of end of dosing) ]

8.  Other Pre-specified:   Number of Participants With Serious Adverse Event (SAEs), Drug-related SAEs, Drug-related AEs, Drug-related AEs Leading to Discontinuation, and All Deaths   [ Time Frame: Continuously throughout study to <=30 days after last dose of study drug; included AEs with an onset date >= day 1 and <= last dose date + 30 days ]

9.  Other Pre-specified:   Number of Participants With Drug-Related Adverse Events (AEs) of Special Interest   [ Time Frame: Continuously throughout study to <=30 days after last dose of study drug; included AEs with an onset date >= day 1 and <= last dose date + 30 days ]

10.  Other Pre-specified:   Number of Participants With Abnormalities in Results of Clinical Laboratory Tests in Hematology   [ Time Frame: At baseline, within 3 days prior to each infusion of docetaxel (each cycle) and at end of treatment. If docetaxel is discontinued, every other cycle. ]

11.  Other Pre-specified:   Number of Participants With Abnormalities in Results of Clinical Laboratory Tests Assessing Liver Function, Renal Function, and Electrolytes   [ Time Frame: At baseline, within 3 days prior to each infusion of docetaxel (each cycle), to end of treatment. If docetaxel is discontinued, every other cycle. ]

12.  Other Pre-specified:   Number of Participants With Abnormal Results in Urinalysis   [ Time Frame: At baseline, within 3 days prior to each infusion of docetaxel (each cycle), to end of treatment. If docetaxel is discontinued, every other cycle. ]

13.  Other Pre-specified:   Number of Participants by Maximal On-study Fridericia-corrected QTc Interval   [ Time Frame: At baseline, approximately 12 weeks after starting treatment, and then whenever clinically indicated up to within 30 days of end of dosing ]

14.  Other Pre-specified:   Number of Participants With Changes From Baseline in Fridericia-corrected QTc Interval   [ Time Frame: At baseline, approximately 12 weeks after starting treatment, and then whenever clinically indicated up to within 30 days of end of dosing ]

15.  Other Pre-specified:   Number of Participants With and Without Pericardial Effusion at Baseline and On-study and With Left Ventricular Ejection Fraction (LVEF) <40% and >=40% On-study   [ Time Frame: At baseline, approximately 12 weeks after start of treatment, and thereafter whenever clinically indicated ]
