Phase IV clinical trial - Prostate

Primary Objective:;To compare the radiographic progression-free survival (rPFS) of chemotherapy (cabazitaxel plus prednisone, Arm A) versus AR-targeted therapy (enzalutamide or abiraterone acetate plus prednisone, Arm B) in mCRPC patients who have been treated with docetaxel and who had disease progression while receiving AR-targeted therapy within 12 months of AR treatment initiation (=12 months, either before or after docetaxel).;The duration of the study per patient will be approximately 2 years. Each patient will be treated until radiographic disease progression, unacceptable toxicity, or patient's refusal of further study treatment, and each patient will be followed after completion of study treatment until death, study cutoff date, or withdrawal of patient consent.
