SOUTH SAN FRANCISCO, Calif., Feb. 14, 2011 (GLOBE NEWSWIRE) -- OXiGENE, Inc. (Nasdaq:OXGN), a clinical-stage, biopharmaceutical company developing novel therapeutics to treat cancer and eye diseases, announced today that it has entered into a Cooperative Research and Development Agreement with the National Cancer Institute’s (NCI) Cancer Therapy Evaluation Program (CTEP) to collaborate on the conduct of a randomized Phase 2 trial of ZYBRESTAT in combination with bevacizumab in patients with relapsed ovarian cancer. Under the terms of the agreement, OXiGENE will provide ZYBRESTAT to NCI for an NCI-sponsored study conducted by the Gynecologic Oncology Group (GOG), an organization dedicated to clinical research in the field of gynecologic cancer. The aim of the trial will be to determine if the combination of ZYBRESTAT and bevacizumab will enhance anti-tumor effects and further delay tumor progression when compared to bevacizumab alone. OXiGENE anticipates that investigators will initiate enrollment in this Phase 2 study in the first quarter of 2011. The primary endpoint of the study will be progression-free survival, with results expected to become available in early 2013.
