OncoMed to Present Data on Multiple Anti-Cancer Stem Cell Candidates at the American Association of Cancer Research Meeting

REDWOOD CITY, Calif., March 19, 2015 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals Inc. (Nasdaq:OMED) will present new data related to its clinical and preclinical anti-cancer stem cell and immuno-oncology candidates in a total of seven presentations at the upcoming American Association of Cancer Research (AACR) Meeting to be held April 18-22, 2015 in Philadelphia, PA.

Among the presentations will be data looking at synergies between anti-DLL4 and anti-PD1 antibodies, as well as between Wnt-pathway inhibitors and taxanes; biomarker research for tarextumab (anti-Notch2/3), brontictuzumab (anti-Notch1) and anti-RSPO3; and research related to the Hippo anti-cancer stem cell pathway. The following abstracts have been selected for presentation by OncoMed scientists:

About OncoMed Pharmaceuticals

OncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel therapeutics targeting cancer stem cells (CSCs). OncoMed has six anti-cancer product candidates in clinical development, the most advanced of which are in randomized Phase 2 clinical trials. Demcizumab (anti-DLL4, OMP-21M18), tarextumab (anti-Notch2/3, OMP-59R5), brontictuzumab (anti-Notch1, OMP-52M51), anti-DLL4/VEGF bispecific antibody (OMP-305B83), vantictumab (anti-FZD7, OMP-18R5), and ipafricept (FZD8-Fc, OMP-54F28) each target key cancer stem cell signaling pathways including Notch and Wnt. OncoMed plans to file an Investigational New Drug application in early 2015 for anti-RSPO3 (OMP-131R10), an antibody targeting a third key cancer stem cell signaling pathway called R-spondin-LGR. OncoMed is also pursuing discovery of additional novel anti-CSC and cancer immune-oncology product candidates. OncoMed has formed strategic alliances with Celgene Corporation, Bayer Pharma AG and GlaxoSmithKline (GSK). Additional information can be found at the company's website:
