CARLSBAD, Calif., Dec. 3 /PRNewswire-FirstCall/ -- Isis Pharmaceuticals, Inc. (Nasdaq: ISIS) announced today that OncoGenex Pharmaceuticals, Inc. provided positive survival results from a randomized Phase 2 clinical trial of OGX-011 in combination with docetaxel and prednisone ("the OGX-011 arm") compared to docetaxel and prednisone alone ("the control arm") for first-line treatment of metastatic castrate resistant prostate cancer. The current 10.6 month median overall survival advantage observed in the OGX-011 arm represents an increase over the median survival observed in the control arm. OGX-011 was jointly discovered by Isis and the initial development was conducted by Isis and OncoGenex. OGX-011 is now being developed by OncoGenex.

"The progress our partners are making with antisense drugs discovered using Isis' antisense technology demonstrates the value of our technology to create drugs that are first-in-class and may provide new treatment options in a broad range of diseases, including cancer," said Stanley Crooke, Chairman and Chief Executive Officer of Isis. "We are encouraged by the latest results from OGX-011 and look forward to OncoGenex announcing the full results of the study next year."

According to OncoGenex' announcement, the Phase 2 randomized study in 82 patients with metastatic or locally recurring prostate cancer refractory to hormone therapy showed a median survival of 27.5 months for the patients in the OGX-011 arm and 16.9 months for patients in the control arm. Results currently indicate that patients in the OGX-011 arm have a death rate approximately 40% lower than patients in the control arm. The current results were based on study data with a median follow-up of approximately 30 months for both arms. OncoGenex indicates that additional survival updates will be needed before mature me
