Pharmacology

Bevacizumab is a VEGF inhibitor that binds VEGF and prevents its interaction with receptors Flt-1 and KDR on endothelial cells, inhibiting endothelial cell proliferation and new blood vessel formation, thereby reducing tumor microvascular growth and metastatic disease progression.

EGFR antagonist; cetuximab is a recombinant human/mouse chimeric IgG1 monoclonal antibody that binds specifically to the extracellular domain of EGFR, competitively inhibiting EGF and other ligand binding, blocking receptor-associated kinase phosphorylation, inhibiting cell growth, inducing apoptosis, decreasing matrix metalloproteinase and VEGF production, and mediating antibody-dependent cellular cytotoxicity (ADCC) against certain human tumor types.
