  Purpose

This is a pilot study of abiraterone acetate in African American/Black patients with castration-resistant prostate cancer. The primary objective is to determine the correlation between germline polymorphisms and antitumor activity (as defined by a decline in PSA of ≥ 30%) in African American patients with castration-resistant prostate cancer treated with abiraterone acetate. Patients will receive abiraterone acetate until the time of disease progression, in the absence of prohibitive toxicities. Patients will be followed for disease progression and survival.

Primary Outcome Measures:
  • The percent change in PSA [ Time Frame: baseline and 12 weeks ] [ Designated as safety issue: No ]
    The primary objective of this study is to determine a correlation between inherited genetic polymorphisms and antitumor activity (as defined by a decline in PSA of ≥ 30%) in AA patients with castration-resistant prostate cancer treated with Abiraterone. The primary endpoint is the percent change in PSA from baseline to 12 weeks. A decline of ≥ 30% will be correlated with germline SNPs.


Secondary Outcome Measures:
  • Time to progression [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]
    • To determine the time to progression (as per PCWG2 guidelines)
    • Post-treatment changes in measurable disease (as per PCWG2 guidelines)

  • RECIST [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]
    To determine post-treatment changes in measurable disease by RECIST

  • bone scan [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]
    To determine post-treatment changes in bone scans (as per PCWG2 guidelines) ("no new lesions" versus "new lesions.")

  • safety of abiraterone [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]
    To determine the safety of abiraterone Adverse events as defined by CTCAE v4

  • Testosterone [ Time Frame: up to 12 weeks ] [ Designated as safety issue: Yes ]
    Post-treatment changes in testosterone

Exclusion Criteria:

  • Active infection or other medical condition that would make prednisone/prednisolone (corticosteroid) use contraindicated
  • Known brain metastasis
  • Uncontrolled hypertension (systolic BP ≥ 160 mmHg or diastolic BP ≥ 95 mmHg) Patients with a history of hypertension are allowed provided blood pressure is controlled by anti-hypertensive treatment

  • Have poorly controlled diabetes
  • Have a history of gastrointestinal disorders (medical disorders or extensive surgery) that may interfere with the absorption of the study agents
  • Have a pre-existing condition that warrants long-term corticosteroid use in excess of study dose
  • Have known allergies, hypersensitivity, or intolerance to abiraterone acetate or prednisone or their excipients
