Definition

A humanized monoclonal antibody directed against human vascular endothelial growth factor receptor 2 (VEGFR-2; VEGFR2) with potential anti-angiogenesis and antineoplastic activities. Upon administration, anti-VEGFR2 monoclonal antibody MSB0254 specifically binds to and inhibits VEGFR2, which may inhibit tumor angiogenesis and tumor cell proliferation. VEGFR2, a tyrosine-protein kinase that plays an essential role in angiogenesis and the proliferation, survival, migration and differentiation of endothelial cells, is overexpressed in certain tumor types.
