藥理
Antineoplastic Agent, Vascular Endothelial Growth Factor (VEGF) Inhibitor
Ramucirumab has a high affinity for VEGFR2, binding to it and blocking binding of VEGFR ligands, VEGF-A, VEGF-C, and VEGF-D to inhibit activation of VEGFR2, thereby inhibiting ligand-induced proliferation and migration of endothelial cells. VEGFR2 inhibition results in reduced tumor vascularity and growth.
