A fully human IgG2 monoclonal antibody directed against the human hepatocyte growth factor (HGF) with potential antineoplastic activity. Anti-HGF monoclonal antibody AMG 102 binds to and neutralizes HGF, preventing the binding of HGF to its receptor c-Met and so c-Met activation; inhibition of c-Met-mediated signal transduction may result in the induction of apoptosis in cells expressing c-Met.c-Met (HGF receptor or HGFR), a receptor tyrosine kinase overexpressed or mutated in a variety of epithelial cancer cell types, plays a key role in cancer cell growth, survival, angiogenesis, invasion, and metastasis.
