In conjunction with The Royal Marsden NHS Foundation Trust, the ICR tested a promising new prostate cancer drug called abiraterone, which it discovered and developed. A randomised placebo-controlled Phase III trial reported in October 2010 that abiraterone could extend survival in some men with late stage prostate cancer. The trial, funded by Janssen Pharmaceutical Companies, included 1,195 patients from 13 countries whose advanced prostate cancer had stopped responding to standard therapies. Abiraterone extended the average overall survival of patients from 10.9 months to 14.8 months compared to a placebo, without many of the unpleasant side-effects associated with conventional chemotherapy. The FDA in April 2011 approved the drug for sale in the US under the trade name Zytiga.
