Published: Oct 01, 2012
SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Exelixis, Inc. (NASDAQ:EXEL) today announced interim data from 51 patients with metastatic castration-resistant prostate cancer (CRPC) and bone metastases receiving a 40 mg daily dose of cabozantinib in an ongoing non-randomized expansion (NRE) cohort of a phase 2 randomized discontinuation trial. The data suggest that the 40 mg daily dose has similar clinical activity to the 100 mg daily dose previously reported from this trial for key parameters, including reduction of metastatic bone and soft tissue disease, and reduction of bone-related pain and narcotic use, with apparent improvement in adverse event rates and tolerability. Johann de Bono, M.D., Ph.D., leader of the prostate cancer targeted therapy team at The Institute of Cancer Research, London, and honorary consultant at The Royal Marsden NHS Foundation Trust, and an investigator on the trial, presented the data today in an oral presentation session on prostate cancer at the European Society for Medical Oncology (ESMO) 2012 Annual Meeting (Abstract #897O) in Vienna, Austria.
