Summary
The purpose of this study is to evaluate the safety and efficacy of abiraterone acetate when co-administered with prednisone in Asian patients with metastatic castration-resistant prostate cancer (mCRPC) who have failed docetaxel-based chemotherapy.

- Known brain metastasis
- Prior therapy with abiraterone acetate or other CYP17 inhibitor(s), or investigational agent(s) targeting the androgen receptor for metastatic prostate cancer
- Prior therapy with ketoconazole for prostate cancer
- Surgery or local prostatic intervention within 30 days of the first dose
- Radiotherapy, chemotherapy, or immunotherapy within 30 days, or single fraction of palliative radiotherapy within 14 days of administration of Cycle 1 Day 1
- Any acute toxicities due to prior chemotherapy and/or radiotherapy that have not resolved to a National Cancer Institute-Common Terminology Criteria for Adverse Events grade of <=1 (chemotherapy induced alopecia and grade 2 peripheral neuropathy is allowed)
- Current enrollment in an investigational drug or device study or participation in such a study within 30 days of Cycle 1 Day 1
- Anti-androgen treatment must not be given within 4 weeks (flutamide) or 6 weeks (bicalutamide or nilutamide) prior to Cycle 1 Day 1
- Prior systemic treatment with an azole drug (eg, fluconazole, itraconazole) within 4 weeks prior to Cycle 1 Day 1
- Has known allergies, hypersensitivity, or intolerance to abiraterone acetate or its excipients
- Has contraindications to the use of prednisone per local prescribing information
- Has any condition that, in the opinion of the investigator, would make participation not be in the best interest (eg, compromise the well-being) of the patient or that could prevent, limit, or confound the protocol-specified assessments
