NCIt definition : A glycoengineered monoclonal antibody directed against the epidermal growth factor
receptor (EGFR) with potential antineoplastic activity. Imgatuzumab binds to the extracellular
domain of EGFR, preventing the activation and subsequent dimerization of the receptor;
the decrease in receptor activation and dimerization may result in an inhibition of
downstream ERK and JNK signaling pathways and so inhibition of EGFR-dependent tumor
cell proliferation and metastasis. EGFR, a member of the epidermal growth factor family
of extracellular protein ligands, may be overexpressed on the cell surfaces of various
solid tumor cell types.;
