Summary
Brief summary (as posted)
The purpose of this study is to determine the effect of abiraterone acetate plus prednisone on the conduction of electric charges within the heart and to determine the blood levels of abiraterone acetate following administration in patients with metastatic castration-resistant prostate cancer.
