What was measured

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Outcome of an AE was response to a question answered by the investigator: 'Is the AE leading to study discontinuation or death?' as 'yes'.

Analysis population: Safety population included all participants who received any amount of study drug.

Groups in this outcome

Enzalutamide 160 mg

Participants who only received enzalutamide 160 mg as four 40 mg capsules, orally once daily in the study.

Enzalutamide Crossing Over to Abiraterone + Prednisone

Participants who received (after switching from enzalutamide), abiraterone 1000 mg as four 250 mg tablets, orally once daily and prednisone 10 mg administered as two 5 mg tablets, orally twice daily in the study.

Enzalutamide 160mg+Abiraterone 1000mg+ Prednisone 10mg

Participants who received enzalutamide 160 mg as four 40 mg capsules, orally once daily along with abiraterone 1000 mg as four 250-mg tablets, orally once daily and prednisone 5 mg tablet, orally twice daily in the study.

Placebo+Abiraterone 1000mg+ Prednisone 10mg

Participants who received placebo matched to enzalutamide as four 40 mg capsules, orally once daily along with abiraterone 1000 mg as four 250-mg tablets, orally once daily and prednisone 5 mg tablet, orally twice daily in the study.
