NCIt definition : A synthetic, orally available inhibitor of vascular endothelial growth factor receptor
2 (VEGFR2, also known as KDR/FLK-1) tyrosine kinase with potential antineoplastic
activity. Lenvatinib blocks VEGFR2 activation by VEGF, resulting in inhibition of
the VEGF receptor signal transduction pathway, decreased vascular endothelial cell
migration and proliferation, and vascular endothelial cell apoptosis.;
