Must not have received ketoconazole, aminoglutethimide, or abiraterone acetate. Must not have received any prior cytotoxic chemotherapy for metastatic prostate cancer. At least 2 yrs since last cytotoxic chemotherapy in the neoadjuvant and/or adjuvant setting. Prior surgery, and current/planned bone targeting agents are allowed. Pts must not have plans to receive experimental therapy or LHRH antagonists. Pts must have had no more than 30 days since prior castration (medical or surgical). Pts must have a PSA>/=2 ng/mL. Pts must have a DEXA bone scan within the past 2yrs. Pts must not have Grade III/IV heart failure at time of screening. Pts must not have any thromboembolic event, unstable angina pectoris, MI, or serious uncontrolled cardiac arrhythmia w/in 6 mo prior to registration.
