Expanded Phase of Trial will Assess anti-TIGIT in Combination with anti-PD1
REDWOOD CITY, Calif., June 12, 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 the first patient has been dosed in the company's Phase 1b portion of the Phase 1a/1b clinical trial of anti-TIGIT (OMP-313M32) in combination with anti-PD1 (nivolumab). TIGIT (T-cell immunoreceptor with Ig and ITIM domains) is a next generation checkpoint receptor, and upon activation by the PVR ligand, a protein broadly expressed on tumor cells, it blocks T-cell activation. OncoMed's anti-TIGIT candidate is an IgG1 monoclonal antibody checkpoint inhibitor which binds to the human TIGIT receptor on T-cells with a goal of improving the activation and effectiveness of T-cell and NK cell tumor-killing activity.
"The dosing of the first patient in the Phase 1b portion of the anti-TIGIT trial marks an important milestone in the advancement of this therapeutic candidate through the clinic, where we will be evaluating the potential synergy of our anti-TIGIT monoclonal antibody with anti-PD1," said John Lewicki, Ph.D., president and chief executive officer of OncoMed. "We look forward to continuing our exploration of the potential anti-tumor activity of anti-TIGIT and its ability to combine safely with anti-PD1 in key clinical oncology settings. Simultaneously, dose escalation in the Phase 1a portion of the trial is nearing completion and dose expansion in select tumor types is planned."
