Ramucirumab is an antineoplastic agent and direct VEGFR2 (vascular endothelial growth factor receptor 2) antagonist that blocks the binding of natural VEGF ligands, which are secreted by solid tumors to promote angiogenesis and enhance tumor blood supply.

Ramucirumab is a human monoclonal antibody (IgG1) against vascular endothelial growth factor receptor 2 (VEGFR2), a type II trans-membrane tyrosine kinase receptor expressed on endothelial cells. By binding to VEGFR2, ramucirumab prevents binding of its ligands (VEGF-A, VEGF-C, and VEGF-D), thereby preventing VEGF-stimulated receptor phosphorylation and downstream ligand-induced proliferation, permeability, and migration of human endothelial cells.
Ramucirumab is indicated for the treatment of advanced or metastatic gastric or gastro-esophageal junction adenocarcinoma as a single agent or in combination with paclitaxel for patients who progress after prior fluoropyrimidine- or platinum-containing chemotherapy. It is indicated, in combination with erlotinib, for the first-line treatment of metastatic non-small cell lung cancer with epidermal growth factor exon 19 deletions or exon 21 (L858R) point mutations. It is also indicated in combination with docetaxel for the treatment of metastatic non-small cell lung cancer in patients who have progressed following prior platinum-based chemotherapy. Patients who have EGFR or ALK genomic aberrations should also have disease progression following FDA-approved therapy for these aberrations. Ramucirumab, in combination with FOLFIRI (folinic acid, fluorouracil, and irinotecan), is indicated for the treatment of metastatic colorectal cancer in patients who have progressed following therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine. Lastly, ramucirumab is indicated for the treatment of hepatocellular carcinoma in patients with an alpha-fetoprotein level ≥400 ng/mL and have previously been treated with sorafenib.
