A Canadian Observational Study in Metastatic Cancer of the Prostate: A Study of ZYTIGA Use in the Community Urology Setting

Participants will not receive any intervention in this study. The chemotherapy-naive metastatic castrate-resistant prostate cancer (mCRPC) participants who, on failing conventional androgen deprivation therapy (ADT), are prescribed to initiate Abiraterone Acetate (ZYTIGA) therapy as part of their physician's treatment approach for their asymptomatic or mildly symptomatic disease, will be observed in this study. Participants will receive standard of care therapy.
