About Anti-RSPO3OncoMed is currently enrolling patients in an ongoing Phase 1a/b clinical trial of anti-RSPO3 that was started in July 2015. The Phase 1a/b trial initially enrolled patients with advanced refractory solid tumors and includes an expansion arm for biomarker-selected patients to receive single-agent therapy. The Phase 1b portion, which began enrollment in January 2016, is testing anti-RSPO3 with FOLFIRI in patients with second-line metastatic colorectal cancer. Anti-RSPO3 is believed to be the first drug candidate in its class to target the R-spondin-LGR pathway, an important cancer stem cell pathway identified by OncoMed researchers. About Anti-DLL4/VEGFOncoMed initiated a single-agent study of its anti-DLL4/VEGF bispecific in January 2015 in patients with advanced refractory solid tumors. Dose escalation is completed in the Phase 1a trial and enrollment in an expansion cohort is ongoing. The anti-DLL4/VEGF bispecific antibody is designed to combine the anti-cancer stem cell, dysangiogenic and immunotherapy mechanisms of anti-DLL4 with the anti-angiogenic activity of an anti-VEGF agent. The bispecific antibody was discovered using OncoMed's proprietary MAbTrap™ antibody display technology, which enables the rapid identification of monoclonal antibodies that bind targets with high affinity and specificity. The antibody is the first program based on OncoMed's BiMAb™ bispecific platform technology to enter clinical testing. About OncoMed PharmaceuticalsOncoMed Pharmaceuticals is a clinical-stage company focused on discovering and developing novel anti-cancer stem cell and immuno-oncology therapeutics. OncoMed has seven anti-cancer therapeutic candidates in clinical development, including 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), ipafricept (FZD8-Fc, OMP-54F28), and anti-RSPO3 (OMP-131R10), which each target key cancer stem cell signaling pathways including Notch, Wnt and R-spondin LGR. OncoMed is advancing its wholly owned GITRL-Fc candidate and an undisclosed immuno-oncology candidate (IO#2) toward clinical trials in the 2016-2017 timeframe. OncoMed has formed strategic alliances with Celgene Corporation, Bayer Pharma AG and GlaxoSmithKline (GSK). Additional information can be found at the company's website: www.oncomed.com.
