Cabazitaxel Versus the Switch to Alternative AR Targeted Therapy Enzalutamide or Abiraterone in Metastatic Castration-Resistant Prostate Cancer (mCRPC) Primary Resistant Patients to Abiraterone or Enzalutamide (PRIMCAB)
Phase II, Randomized, Open-label, Multicenter Study in Chemotherapy-naïve Metastatic Castration-Resistant Prostate Cancer (mCRPC) Patients Who Have PRIMary Resistance to Abiraterone Acetate or Enzalutamide Treatment Comparing the Anti-tumor Effect of CABazitaxel to Alternative Androgen Receptors (AR) Targeted Therapy
Primary Objective:
To demonstrate the superiority in term of radiographic Progression-Free Survival (rPFS) of cabazitaxel at at 25 milligram per meter square (mg/m^2) plus prednisone (Arm A) versus either enzalutamide at 160 milligram (mg) once daily or abiraterone acetate at 1000 mg once daily plus prednisone (Arm B) in chemotherapy-naïve participants with metastatic Castration-Resistant Prostate Cancer (mCRPC) who have disease progression while receiving androgen receptor (AR) targeted therapy (abiraterone plus prednisone or enzalutamide) within 12 months of treatment initiation (≤12 months).
Secondary Objective:
- To compare efficacy for:
- Prostate-specific antigen (PSA) response rate and Time to PSA progression (TTPP).
- Progression Free Survival (PFS).
- Overall Survival (OS).
- Tumor response rate in participants with measurable disease (RECIST 1.1)
- Pain response and time to pain progression.
- Symptomatic skeletal events (SSE) rate and time to occurrence of any SSE.
- To analyze messenger ribonucleic acids (mRNAs) including androgen-receptor splice variant 7 messenger RNA (AR-V7) as a biomarker in Circulating Tumor Cells (CTCs).
- To evaluate safety in the 2 treatment arms.
