Cetuximab
nci_thesaurus_definition
A recombinant, chimeric monoclonal antibody directed against the epidermal growth factor (EGFR) with antineoplastic activity. Cetuximab binds to the extracellular domain of the EGFR, thereby preventing the activation and subsequent dimerization of the receptor; the decrease in receptor activation and dimerization may result in an inhibition in signal transduction and anti-proliferative effects. This agent may inhibit EGFR-dependent primary tumor growth and metastasis. EGFR is overexpressed on the cell surfaces of various solid tumors.

drug_mechanism_of_action
Chimeric IgG1 monoclonal antibody against EGFR that binds the receptor’s extracellular domain, blocking ligand binding and dimerization to inhibit downstream RAS–RAF–MEK–ERK and PI3K–AKT signaling, suppressing tumor cell proliferation and survival; Fc region may mediate ADCC.
