Primary Outcome Measures:
  • Prostate specific antigen (PSA) response rate [ Time Frame: Day 1 of treatment Cycles until the date of first documented PSA progression, lost to follow Up or withdrawn consent, as assessed up to 9 months after the last patient is enrolled ] [ Designated as safety issue: No ]
    PSA response rate is defined as the number of patients achieving a PSA decline of at least 50% according to the Prostate-Specific Antigen Working Group (PSAWG) criteria.

Secondary Outcome Measures:
  • Overall survival [ Time Frame: up to 5 years ] [ Designated as safety issue: No ]
    Overall survival is defined as the time interval from the date of the first dose to the date of death.

  • Time to PSA progression [ Time Frame: up to 15 months ] [ Designated as safety issue: No ]
    Time to PSA progression will be measured as the time interval from the date of the first dose to the date of PSA progression as defined in the protocol-specific PSAWG criteria.

  • Objective radiographic response rate (RAD-ORR) [ Time Frame: up to 15 months ] [ Designated as safety issue: No ]
    The objective radiographic response rate (RAD-ORR) is defined as the proportion of patients with measurable lesions with a complete response (CR) or partial response (PR) based on modified response evaluation criteria in solid tumors (RECIST) criteria.

  • Serum testosterone and dehydroepiandrosterone (DHEA) sulfate [ Time Frame: up to 15 months ] [ Designated as safety issue: No ]
  • Number of patients with adverse events [ Time Frame: up to 30 days after the last study medication administration. ] [ Designated as safety issue: Yes ]

Enrollment: 82
Study Start Date: August 2011
Estimated Study Completion Date: September 2016
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Abiraterone actetate and Prednisolone Drug: abiraterone acetate
Type=exact number, unit=mg, number=250, form=tablet, route=oral. Patients will receive 4 tablets of abiraterone acetate at least 1 hour before a meal or 2 hours after a meal any time up to 10 pm every day.
Other Name: JNJ-212082
Drug: prednisolone
Type=exact number, unit=mg, number=5, form=tablet, route=oral. Patients will receive 1 tablet of prednisolone twice daily.

Detailed Description:
This is an open-label (all people know the identity of the intervention), multicenter, single arm (only one treatment group) study to evaluate the efficacy and safety of abiraterone acetate in patients with mCRPC. The study will be divided into screening phase (up to 28 days before enrollment), treatment phase including treatment cycles (each cycle of treatment will be 28 days), and follow-up phase. Approximately 80 patients will be enrolled into this study. Safety evaluations for adverse events, clinical laboratory tests, electrocardiogram and vital signs as well as pharmacokinetic (what the body does to drug) assessments will be conducted in this study. Patients will continue to receive abiraterone acetate plus prednisolone until disease progression or occurrence of unacceptable toxicity.
