OncoMed Begins Dosing In Cancer Trial

By Drug Discovery Trends Editor | January 13, 2011

OncoMed Pharmaceuticals, Inc., a company developing novel therapeutics that target cancer stem cells, announced that patient dosing has commenced in a Phase 1 clinical trial of OMP-59R5 in patients with advanced solid tumor cancers. 

OMP-59R5 is a monoclonal antibody that binds selected Notch receptors and is the first antibody to specifically block these targets to enter human studies. The Phase 1 clinical trial of OMP-59R5 is a single-agent study designed to evaluate the safety of escalating doses of OMP-59R5 in patients who have received prior treatment with standard chemotherapeutics. The study will also assess pharmacokinetics, biomarkers and initial indications of efficacy. The Phase 1 trial is being conducted at leading U.S. cancer treatment centers. Preclinical studies have demonstrated that OMP-59R5 decreases the frequency of tumor-initiating cells across a variety of tumor types.

“The advancement of our second antibody into the clinic represents an important milestone for OncoMed, demonstrating our robust and productive drug discovery capabilities and steady execution on our objectives for our programs,” said Paul Hastings, President and Chief Executive Officer of OncoMed Pharmaceuticals. “In just a few short years, we have established a rich pipeline of first-in-class anti-cancer stem cell therapeutics with the potential to dramatically transform cancer treatment by directly targeting tumor-initiating cells.”

OMP-59R5 is part of OncoMed’s collaboration with GlaxoSmithKline (GSK) and its advancement to the clinic triggers a milestone payment from GSK for the company. In December 2007, OncoMed and GSK entered into a strategic alliance valued at up to $1.4 billion to develop cancer stem cell antibody therapeutics targeting the Notch signaling pathway.  OncoMed is currently conducting Phase 1 single agent and Phase 1b combination studies of its first Notch-pathway candidate, OMP-21M18, in patients with a variety of advanced solid tumors. Preliminary results from OncoMed’s Phase 1 dose-escalating single-agent study of OMP-21M18 demonstrate positive indications of disease control and tumor responses as measured by RECIST criteria. In addition, biomarker measurements show that OMP-21M18 is a potent inhibitor of Notch signaling. Initial data from this ongoing study were presented at the 22nd EORTC-NCI-AACR symposium.
