NCIt definition : A fully human monoclonal antibody targeting the vascular endothelial growth factor
receptor 2 (VEGFR2), with potential antiangiogenic activity. Upon administration,
olinvacimab specifically binds to VEGFR2, thereby preventing the binding of its ligand
VEGF. This may result in the inhibition of tumor angiogenesis and a decrease in tumor
nutrient supply. VEGFR2 is a pro-angiogenic growth factor receptor tyrosine kinase
expressed by endothelial cells, while VEGF is overexpressed in many tumors and is
correlated to tumor progression.;
