REDWOOD CITY, Calif., Jan. 04, 2017 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals, Inc. (NASDAQ:OMED), a clinical-stage company focused on discovering and developing novel anti-cancer stem cell and immuno-oncology therapeutics, today announced dosing of the first patient in a Phase 1b clinical trial of anti-DLL4/VEGF bispecific antibody (OMP-305B83) plus chemotherapy in patients with second-line metastatic colorectal cancer.
The anti-DLL4/VEGF is the first antibody developed utilizing OncoMed's BiMAb™ bispecific platform technology and is designed to have anti-cancer stem cell, immunomodulatory and anti-angiogenic activity. Thirty patients with metastatic colorectal cancer who have failed first-line treatment, typically bevicizumab plus FOLFOX (folinic acid, fluorouracil, oxaliplatin) chemotherapy, will receive second-line treatment in the Phase 1b multicenter, open-label dose escalation and expansion study of the anti-DLL4/VEGF bispecific antibody in combination with FOLFIRI (folinic acid, fluorouracil and irinotecan) chemotherapy. This trial is designed to determine the safety, preliminary efficacy, immunogenicity, pharmacokinetics and biomarker effects of the anti-DLL4/VEGF bispecific antibody plus FOLFIRI. A second Phase 1b study in patients with platinum resistant ovarian cancer is expected to begin enrolling patients soon.
