An Efficacy and Safety Study of Apalutamide (JNJ-56021927) in Combination With Abiraterone Acetate and Prednisone Versus Abiraterone Acetate and Prednisone in Participants With Chemotherapy-naive Metastatic Castration-resistant Prostate Cancer (mCRPC)
Summary
The purpose of this study is to compare the radiographic progression-free survival (rPFS) of apalutamide in combination with abiraterone acetate (AA) plus prednisone or prednisolone (AAP) and AAP in participants with chemotherapy-naive (participants who did not receive any chemotherapy \[treatment of cancer using drugs\]) metastatic castration-resistant prostate cancer (mCRPC) (cancer of prostate gland \[gland that makes fluid that aids movement of sperm\]).
