Cabazitaxel is a microtubule inhibitor approved for the treatment of patients with CRPC (Castrate-Resistant Prostate Cancer) who have progressed on Docetaxel. This agent in a randomized phase III trial (TROPIC) demonstrated a significant improvement in Overall Survival (OS) compared with Mitoxantrone, with a 30% reduction in the risk of death. We now have another option for the treatment of CRPC which until not too long back was considered as a disease for which chemotherapy was not effective.
