REDWOOD CITY, Calif., Oct. 20, 2018 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals, Inc. (NASDAQ:OMED), a clinical-stage biopharmaceutical company focused on discovering and developing novel anti-cancer therapeutics, today announced interim results from its ongoing Phase 1b trial investigating navicixizumab, OncoMed's anti-DLL4/VEGF bispecific antibody, in combination with paclitaxel in patients with platinum-resistant ovarian cancer.
The interim results were presented at the European Society for Medical Oncology in Munich. The patients had received a median of four prior therapies, all of whom had received prior paclitaxel and 69% had received prior bevacizumab. Twentytwo of the 26 patients (85%) treated with the novel regimen experienced clinical benefit. Notably 11 of the 26 patients (42%) achieved a partial response and the median progression-free survival was 5.4 months (95% CI: 3.5-8.0 months). Historical response rates for patients with heavily pretreated platinum-resistant ovarian cancer treated with chemotherapy are typically 15% or less.
