CAMBRIDGE, Ma., July 14, 2008 (PRIME NEWSWIRE) -- Infinity Pharmaceuticals, Inc. (Nasdaq:INFI) today announced that it has decided to discontinue further enrollment in its Phase 2 single agent, signal-finding study of IPI-504 (retaspimycin hydrochloride) in advanced hormone-refractory prostate cancer. Infinity has not observed evidence of biologic activity in the trial and has, therefore, concluded that the overall risk-benefit ratio does not justify continuing a signal-finding study as a single agent in this indication. Biologic activity was not observed in either the fully enrolled group of patients having previously been treated with a docetaxel-based chemotherapy (n=15) or in the group of patients who had not been previously treated with a docetaxel-based chemotherapy (n=4). Patients currently enrolled in this trial may continue receiving IPI-504 after consultation with their physician.
