A Study of Abiraterone Acetate Plus Low-Dose Prednisone Plus Androgen Deprivation Therapy (ADT) Versus ADT Alone in Newly Diagnosed Participants With High-Risk, Metastatic Hormone-Naive Prostate Cancer (mHNPC)
Summary
The purpose of this study is to determine if newly diagnosed (within previous 3 months) participants with metastatic (spread of cancer cells from one part of the body to another ) hormone-naive prostate cancer (mHNPC) who have high-risk prognostic factors will benefit from the addition of abiraterone acetate plus low-dose prednisone to androgen deprivation therapy (ADT; lutenizing hormone releasing hormone \[LHRH\] agonists or surgical castration).
