Onartuzumab is a monovalent antibody that targets the Met receptor. Hepatocyte growth factor (HGF) and its receptor Met can stimulate growth, invasion, and survival in tumor cells. Inhibiting Met receptor and HGF may impact tumor cell proliferation, motility, invasion, and survival and promote tumor regression.
