name:
Monovalent antibody design and mechanism of action of onartuzumab, a MET antagonist with anti-tumor activity as a therapeutic agent.
description:
The epitope-specific antibody onartuzumab inhibits HGF binding to the HGF receptor (MET) more potently than the parent murine/human chimeric antibody chOA5D5. Onartuzumab blocks HGF-alpha, but not HGF-ß, binding to HGF receptor MET. Onartuzumab inhibits HGF-dependent MET phosphorylation and downstream signalling in A549 cells and inhibits HGF-dependent cell proliferation in Ba/F3-huMET cells and other cancer cell lines.
