General Information

This website is designed for healthcare professionals to learn more about an expanded access program (EAP) to provide subjects with the opportunity for treatment with an investigational drug, abiraterone acetate, before Marketing Authorization. Abiraterone acetate is an investigational drug and is not currently approved by the Food and Drug Administration (FDA). The safety and efficacy of abiraterone acetate has not been fully established or thoroughly evaluated by regulatory agencies. In accordance with local regulations, the EAP is either run as a clinical trial or on a named patient basis in a particular country.

Subjects with metastatic, castration-resistant prostate cancer (mCRPC) who have progressed after treatment with taxane-based chemotherapy may be eligible to receive investigational drug based on certain criteria.

This EAP is available to subjects who (not all criteria are listed):

  • Are males age 18 or older
  • Have histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell histology
  • Received at least one, but not more than two cytotoxic chemotherapy regimens for mCRPC. At least one regimen must have contained a taxane such as docetaxel
  • Have had progressive disease according to Prostate Cancer Working Group 2 (PCWG2) Criteria

This EAP is not available to subjects who (not all criteria are listed):

  • Do not have metastatic disease which has become resistant to conventional hormone therapy
  • Have serious or uncontrolled co-existent non-malignant disease, including active and uncontrolled infection
  • Have active or symptomatic viral hepatitis, chronic liver disease, or moderate to severe hepatic function abnormality
  • Have a history of pituitary or adrenal dysfunction
  • Have poorly controlled or uncontrolled hypertension
  • Have uncorrected hypokalemia (low serum levels of potassium)

Subjects will receive an investigational treatment, abiraterone acetate 1,000 mg orally/once daily (administered as four 250 mg tablets) and prednisone or prednisolone 5 mg orally/ twice a day. Subjects will be treated until disease progression.
