Current landscape of treatment of castration-resistant prostate cancer (CRPC) has recently changed. Cabazitaxel, a new taxane with potential antineoplastic activity, has been approved by Food and Drug Administration (FDA) after docetaxel failure. In a phase III trial, cabazitaxel showed increased overall survival (OS) compared with mitoxantrone (15.1 vs. 12.7 mo, HR 0.70, 95% CI 0.59-0.83, p <0.0001). Furthermore, chemotherapy is not the only strategy available: several studies have shown as CRPC remains dependent on androgen receptor function for growth. Abiraterone acetate, an irreversible inhibitor of CYP17, has also been approved by FDA after docetaxel failure. In a phase III trial comparing abiraterone acetate to placebo, abiraterone showed improvement in OS (14.8 vs. 10.4 mo, HR 0.65, 95% CI 0.54-0.77; p <0.0001). This review will discuss current options and the ongoing trials for second-line treatment of CRPC including chemotherapy, hormonal therapies, antiangiogenetic and immune strategies.
