Brief Summary:
The purpose of this study is to evaluate the serum testosterone levels in patients with Metastatic Castration-Resistant Prostate Cancer on SoluMatrix™ Abiraterone Acetate as Compared to Abiraterone Acetate

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: Zytiga® (Abiraterone Acetate) Drug: SoluMatrix™ (Abiraterone Acetate) Phase 2

Detailed Description:
This is 12-week, open-label study of abiraterone acetate in at least 50 patients with metastatic castration-resistant prostate cancer. The primary endpoint is total testosterone at pharmacokinetic steady-state. Additional secondary endpoints include safety assessments, PSA and pharmacokinetic measurements
