Antineoplastics, VEGF Inhibitor
Inhibits the kinase activities of various subtypes of vascular endothelial growth factor (VEGF) receptors.
Lenvatinib is a receptor tyrosine kinase (RTK) inhibitor that inhibits the kinase activities of VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). It also inhibits other RTKs that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1, 2, 3, and 4; the platelet-derived growth factor receptor alpha (PDGFR-α); KIT; and RET. It is indicated for first-line treatment of unresectable HCC.
Vascular endothelial growth factor receptor 2 (VEGFR2) antagonist that specifically binds VEGF receptor 2 and blocks binding of VEGFR ligands, VEGF-A, VEGF-C, and VEGF-D. As a result, ramucirumab inhibits ligand-stimulated activation of VEGF2, thereby inhibiting ligand-induced proliferation, and migration of human endothelial cells. It is indicated as monotherapy for hepatocellular carcinoma (HCC) in patients with alpha fetoprotein (AFP) of 400 ng/mL or higher who have been previously treated with sorafenib.
Bevacizumab (Avastin, Bevacizumab-awwb, Mvasi)
Recombinant humanized monoclonal antibody to VEGF. It blocks the angiogenic molecule VEGF thereby inhibiting tumor angiogenesis, starving tumor of blood and nutrients. It is indicated, in combination with atezolizumab, for unresectable or metastatic HCC who have not received prior systemic therapy.
