Most prostate cancer-related deaths occur in patients with castration-resistant prostate cancer (CRPC). Until recently, only therapy with docetaxel and prednisone has been shown to prolong survival in men with metastatic CRPC. With the United States Food and Drug Administration (US FDA) approvals of sipuleucel-T, cabazitaxel, and abiraterone acetate, all based on improvement in overall survival, the landscape for management of men with metastatic CRPC has dramatically changed. In this review we will discuss the pivotal clinical trial data leading to these approvals, with particular focus on the unique indication for sipuleucel-T and the implications for optimal management and sequencing of treatment in this patient population.
