acetate (INN, USAN, BAN, JAN) (brand names Zytiga, Abiratas, Abretone,
Abirapro) is a steroidal antiandrogen, specifically an androgen synthesis
inhibitor, used in combination with prednisone in metastatic
castration-resistant prostate cancer (previously called hormone-resistant or
hormone-refractory prostate cancer) – i.e., prostate cancer not responding to androgen deprivation or
treatment with androgen receptor antagonists. It is a prodrug to the active
agent abiraterone, and is marketed by Janssen Biotech under the trade name
Zytiga. In addition, Intas Pharmaceuticals markets the drug under the trade
name Abiratas, Cadila Pharmaceuticals markets the drug as Abretone, and
Glenmark Pharmaceuticals as Abirapro.
Abiraterone acetate was approved by the United
States Food and Drug Administration on April 28, 2011. The FDA press release
made reference to a phase III clinical trial in which abiraterone use was
associated with a median survival of 14.8 months versus 10.9 months with placebo;
the study was stopped early because of the successful outcome.
