OncoMed Announces Upcoming Presentation of Navicixizumab Interim Phase 1b Data at the European Society of Clinical Oncology Meeting

REDWOOD CITY, Calif., Oct. 09, 2018 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals, Inc. (NASDAQ:OMED), a clinical-stage biopharmaceutical company focused on discovering and developing novel anti-cancer therapeutics, today announced that interim results of its ongoing Phase 1b study of navicixizumab in combination with paclitaxel in patients with platinum-resistant ovarian cancer will be presented in a poster presentation on October 20, 2018 at the European Society for Medical Oncology meeting to be held in Munich, Germany.

About Navicixizumab
OncoMed's anti-DLL4/VEGF bispecific antibody, navicixizumab, is designed to inhibit the function of both DLL4 and VEGF and thereby induce potent anti-tumor responses while mitigating certain angiogenic-related toxicities. Navicixizumab was developed utilizing OncoMed's BiMAb^™ bispecific platform technology, which enables the design of bispecific antibodies comparable to traditional monoclonal antibodies but possessing dual target-binding specificity. In preclinical studies, navicixizumab demonstrated robust in vivo anti-tumor efficacy across a range of solid tumor xenografts, including colon, ovarian, lung and pancreatic cancers, among others. Further, in preclinical studies dual inhibition of DLL4 and VEGF appeared to exhibit synergistic anti-tumor activity at doses where blockade of either target alone elicited sub-optimal activity. In a Phase 1a study with single-agent navicixizumab published in Investigational New Drugs, 19 of 66 patients with various types of refractory solid tumors had tumor shrinkage following treatment with navicixizumab. Notably, 3 of the 12 (25%) ovarian cancer patients treated in the trial achieved a partial response with single-agent navicixizumab therapy.
