A recombinant, human-mouse chimeric monoclonal antibody directed against the epidermal growth factor receptor (EGFR) with potential antineoplastic activity. Upon intravenous administration, anti-EGFR monoclonal antibody CPGJ 602 targets and binds to EGFR, which prevents receptor dimerization and activation. This leads to an inhibition of EGFR-dependent downstream pathways and EGFR-dependent tumor cell proliferation and metastasis. EGFR, a receptor tyrosine kinase, may be overexpressed on the surfaces of various tumor cell types.
