What was measured

OS was defined as the time from date of randomization to date of death from any cause.

Analysis population: ITT population included all randomized participants classified according to their assigned treatment group, regardless of the actual treatment received.

Groups in this outcome

Placebo + Androgen Deprivation Therapy (ADT)

Participants received matching placebo (4 tablets) orally once daily (qd) along with ADT (gonadotropin releasing hormone analog \[GnRHa\] or surgical castration) as standard of care therapy in each 28-day treatment cycle. The choice of the GnRHa (agonist or antagonist) was at discretion of the investigator. In the event of a positive result at interim or final analysis participants in treatment phase had opportunity to receive Apalutamide +ADT. Participants received treatment until radiographic progression or unequivocal clinical progression, unacceptable toxicity, or death.

Apalutamide + ADT

Participants received JNJ-56021927 (apalutamide) 240 milligrams (mg) (4\*60 mg tablets) orally qd along with ADT (gonadotropin releasing hormone analog \[GnRHa\] or surgical castration) as standard of care therapy in each 28-day treatment cycle. The choice of the GnRHa (agonist or antagonist) was at discretion of the investigator. Participants received treatment until radiographic progression or unequivocal clinical progression, unacceptable toxicity, or death.
