Vandetanib (Caprelsa)

General information

Class/mechanism: from the NCI Drug Dictionary: "An orally bioavailable 4-anilinoquinazoline. Vandetanib selectively inhibits the tyrosine kinase activity of vascular endothelial growth factor receptor 2 (VEGFR2), thereby blocking VEGF-stimulated endothelial cell proliferation and migration and reducing tumor vessel permeability. This agent also blocks the tyrosine kinase activity of epidermal growth factor receptor (EGFR), a receptor tyrosine kinase that mediates tumor cell proliferation and migration and angiogenesis." Also a tyrosine kinase inhibitor of RET (rearranged during transfection), BRK (breast tumor kinase/protein tyrosine kinase 6), TIE2, EPH, Src. Inhibits angiogenesis, endothelial cell migration, and tumor growth.
Route: PO
Extravasation: n/a
