What was measured

Time 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.

Analysis population: ITT analysis set included all subjects randomized into the study and who were classified according to their assigned treatment group, regardless of the actual treatment received.

Groups in this outcome

Abiraterone Acetate+Prednisone+ADT

Participants received abiraterone acetate tablet at a total dose of 1000 milligram (mg) plus 5 mg capsule of prednisone orally once daily until disease progression, withdrawal of consent or unacceptable toxicity. Stable regimen of androgen deprivation therapy (ADT) was administered.

Placebo + ADT

Participants received placebo matched to abiraterone acetate plus prednisone orally once daily until disease progression, withdrawal of consent or unacceptable toxicity. Stable regimen of ADT was administered.
