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
Cetuximab is an IgG1 monoclonal antibody that binds the extracellular domain of EGFR, blocking ligand binding, receptor activation and dimerization, thereby inhibiting downstream signaling (e.g., RAS/RAF/MEK/ERK and PI3K/AKT) and tumor cell proliferation; its Fc domain can also engage Fcγ receptors to mediate antibody-dependent cellular cytotoxicity (ADCC) against EGFR-expressing tumor cells.
