ORLANDO, Fla. and CARLSBAD, Calif., June 1 /PRNewswire-FirstCall/ -- Isis Pharmaceuticals, Inc. (Nasdaq: ISIS) announced today that Isis' collaborators presented new clinical data on drugs in Isis' partnered oncology franchise at this year's American Society of Clinical Oncology (ASCO) Annual Meeting in Orlando, Florida. In total, four presentations were featured on three drugs in Isis' oncology pipeline, including results from a Phase 2 study of OGX-011 in patients with advanced metastatic prostate cancer and Phase 1 study of OGX-427 in patients with a variety of cancers. OGX-011 and OGX-427 are antisense drugs co-discovered by Isis and OncoGenex (Nasdaq: OGXI) and Isis licensed its rights to OGX-011 to OncoGenex Pharmaceuticals, Inc. In addition, new results from a Phase 1 trial evaluating LY2181308, an antisense drug discovered by Isis and licensed to Eli Lilly and Company, in patients with cancer were also presented. Both Lilly and OncoGenex are also developing additional anti-cancer drugs in Isis' oncology franchise.
"Oncology is one of the many different therapeutic applications of our technology. Our drug discovery platform offers us virtually unlimited opportunities to expand the scope of diseases we can treat with antisense drugs," said Brett Monia, Ph.D., Vice President of Drug Discovery and Corporate Development at Isis Pharmaceuticals. "We are encouraged by the progress our partners are making with the four anti-cancer drugs in our pipeline. The positive data our partners have reported plus the exciting work from our research efforts on new anti-cancer targets have compelled us to reinvigorate our internal cancer program. We expect to have exciting new cancer drugs to enter development in the next 12 to 18 months."
On Saturday, May 30, Dr. Kim Nguyen Chi, principle investigator and a medical oncologist at BC Cancer Agency - Vancouver Centre, presented the final results of a randomized Phase 2 trial of OGX-011 in patients with advanced metastatic prostate cancer. In this trial, OncoGenex reported that a median overall survival was observed in patients treated with OGX-011 plus docetaxel of 23.8 months compared to 16.9 months for patients treated with docetaxel alone, the current standard of care for patients with advanced metastatic prostate cancer. In addition, OncoGenex reported that the unadjusted hazard ratio, a measure used to determine the difference in survival between treatment groups was 0.61, representing a 39% reduction in the rate of death for patients treated with OGX-011. OGX-011 continues to be well tolerated in combination with docetaxel. Based on clinical results to date, OncoGenex has said that it intends to conduct Phase 3 registration trials with OGX-011 in metastatic castrate resistant prostate cancer, subject to securing a development partner or the receipt of additional funding.
Dr. Sebastien Hotte, principle investigator and medical oncologist at Juravinski Cancer Centre, Hamilton, Ontario, presented new data on Saturday May 30 from a Phase 1 study on OGX-427 in patients with a variety of cancers. In this study, Dr. Hotte reported declines in circulating tumor cells at all doses evaluated as well as evidence of reduction in tumor markers defined as declines of PSA levels in prostate cancer or CA-125 levels in ovarian cancer. For further details on both the OGX-011 and OGX-427 study results, please see OncoGenex' releases that were issued on Saturday May 30, 2009.
Also on Saturday May 30, Dr. Denis Talbot, clinical investigator and medical oncologist in the Medical Oncology Unit at The Churchill Hospital, Oxford Radcliffe Hospitals NHS Trust, presented new data from a Phase 1 study of LY2181308 in patients with cancer. The new data confirmed that LY2181308 penetrates tumor tissue and reduces survivin mRNA and protein levels in tumor cells. In addition, Dr. Azeem Saleem, CRUK Senior Clinical Research Fellow, University of Manchester, presented results of a pharmacokinetic study of LY2181308 in patients with cancer. Using state-of-the-art imaging techniques to assess radiolabeled LY2181308 distribution in humans, Dr. Saleem reported that LY2181308 effectively penetrated tumor tissues. LY2181308 is currently being evaluated in two separate Phase 2 studies in patients with relapsed or refractory acute myeloid leukemia, and as a combination therapy in patients with hormone refractory prostate cancer.
