This trial will determine whether any benefit is gained by adding chemotherapy before hormonal therapy to hormonal therapy alone in the population of subjects with metastatic or high risk disease. Two therapeutic approaches will be compared in this two-arm randomized clinical trial. The control Arm A provides hormonal therapy alone. The experimental Arm B involves treatment with hormone therapy + Cabazitaxel 25 mg / m² / day on day 1 every 3 weeks continued if the patient has stable or responding disease up to 10 cycles. For the schematic representation of study design please see Section 7.3.1.
