drug_description
EGFR/HER1 monoclonal antibody given IV; binds EGFR to prevent ligand binding and dimerization, promotes receptor downregulation and ADCC, reducing signaling through RAS/RAF/MEK/ERK and PI3K/AKT pathways.

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 targeting EGFR (HER1). Binds the extracellular domain to block ligand binding and receptor dimerization, promotes receptor internalization/downregulation, suppresses RAS/RAF/MEK/ERK and PI3K/AKT signaling, and can induce Fc-mediated ADCC against EGFR-expressing tumor cells.
