Trial Title: Cabazitaxel Versus the Switch to Alternative AR-targeted Agent (Enzalutamide or Abiraterone) in Metastatic Castration-resistant Prostate Cancer (mCRPC) Patients Previously Treated With Docetaxel and Who Rapidly Failed a Prior AR-targeted Agent

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion criteria :~Histologically confirmed prostate adenocarcinoma.~* Metastatic disease.~* Effective castration with serum testosterone levels less than (\<)0.5 ng/mL. If the participant has been treated with Luteinizing hormone-releasing hormone agonist (LHRH) agonists or antagonist (i.e., without orchiectomy), then this therapy should be continued.~* Progressive disease defined by at least one of the following:~* Progression in measurable disease (RECIST 1.1 criteria).~* Appearance of 2 or more new bone lesions (PCWG2).~* Rising Prostate Specific Antigen (PSA) (PCWG2).~* Having received prior docetaxel for at least 3 cycles (before or after an AR-targeted therapy). Docetaxel administration in combination with androgen deprivation therapy (ADT) in metastatic hormone-sensitive disease was considered a prior exposure. Docetaxel rechallenge was allowed.~* Having progressive disease (PD) while receiving AR-targeted therapy with abiraterone acetate or enzalutamide within 12 months of AR treatment initiation (\<=12 months), even if treatment duration was longer than 12 months. Participants treated with Abiraterone Acetate + ADT in metastatic hormone-sensitive setting were eligible in the study if they have progressed within 12 months with the AR-targeted agent. Participants having PSA progression only (as per PCWG2) within 12 months were eligible.~* A PSA value of at least 2 ng/mL was required at study entry.~* Prior AR-targeted therapy (abiraterone acetate or enzalutamide) must be stopped at least 2 weeks before study treatment.~* Signed informed consent.~Exclusion criteria:~* Prior chemotherapy other than docetaxel for prostate cancer, except estramustine and except adjuvant/neoadjuvant treatment completed \>3 years ago.~* Less than 28 days elapsed from prior treatment with chemotherapy, immunotherapy, radiotherapy, or surgery to the time of randomization.~* Adverse events (excluding alopecia and those listed in the specific exclusion criteria) from any prior anticancer therapy of Grade \>1 (National Cancer Institute Common Terminology Criteria \[NCI CTCAE\] v4.0) at the time of randomization.~* Eastern Cooperative Oncology Group performance status (ECOG PS) \>2 (ECOG 2 must be related to prostate cancer, not to other comorbidities).~* Prior malignancy. Adequately treated basal cell or squamous cell skin or superficial (pTis, pTa, and pT1) bladder cancer were allowed, as well as any other cancer for which treatment has been completed \>=5 years ago and from which the participant has been disease-free for \>=5 years.~* Participation in another clinical trial and any concurrent treatment with any investigational drug within 30 days prior to randomization.~* Acquired immunodeficiency syndrome (AIDS-related illnesses) or known human immunodeficiency virus (HIV) disease requiring antiretroviral treatment.~* Participants with reproductive potential who do not agree, in conjunction with their partner, to use accepted and effective method of contraception during the study treatment period and up to 6 months after the last administered dose. The definition of effective method of contraception described hereafter: oral contraceptives, combined hormonal intravaginal, transdermal, intra uterine device or condoms was based on respective study treatment labelling and country-specific regulatory requirements, and were documented in the Informed Consent Form.~* Known allergies, hypersensitivity or intolerance to prednisone or excipients of abiraterone acetate, enzalutamide, docetaxel, or polysorbate 80.~* Known history of mineralocorticoid excess or deficiency.~* History of seizure, underlying brain injury with loss of consciousness, transient ischemic attack within the past 12 months, cerebral vascular accident, brain arteriovenous malformation, brain metastases, or the use of concomitant medications that may lower the seizure threshold.~* Unable to swallow a whole tablet or capsule.~* Inadequate organ and bone marrow function as evidenced by:~* Hemoglobin \<10.0 g/dL;~* Absolute neutrophil count \<1.5 \* 10\^9/L;~* Platelet count \<100 \* 10\^9/L;~* Aspartate aminotransferase/serum glutamic oxaloacetic transaminase and/or alanine aminotransferase/serum glutamic pyruvic transaminase \>1.5 \* the upper limit of normal (ULN);~* Total bilirubin \>1.0 \* ULN;~* Potassium \<3.5 mmol/L;~* Child-Pugh Class C.~* Contraindications to the use of corticosteroid treatment.~* Symptomatic peripheral neuropathy Grade \>=2 (NCI CTCAE v4.0).~* Uncontrolled severe illness or medical condition including uncontrolled diabetes mellitus, history of cardiovascular disease (uncontrolled hypertension, arterial thrombotic events in the past 6 months, congestive heart failure, severe or unstable angina pectoris, recent myocardial infarction within the last 6 months, or uncontrolled cardiac arrhythmia).~* Concomitant vaccination with yellow fever vaccine.~The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Study Arms:
- Cabazitaxel (Type: EXPERIMENTAL): Participants received Cabazitaxel 25 mg/m\^2 intravenous (IV) infusion for over 1 hour on Day 1 of each 3 week treatment cycle in combination with Prednisone 10 mg orally once daily and primary prophylactic granulocyte-colony stimulating factor (G-CSF) as per investigator decision, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 22 weeks).
- Abiraterone acetate or enzalutamide (Type: EXPERIMENTAL): Participants received either abiraterone acetate 1000 mg orally once daily from Day 1 to Day 21 of each 3 week treatment cycle in combination with prednisone 5 mg orally twice daily; or enzalutamide 160 mg orally once daily continuously from Day 1 to Day 21 of each 3 week treatment cycle, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 12.5 weeks).

Based on this trial design, predict the completion outcome and termination type (if applicable).
