Anti-EGFR Monoclonal Antibody Mixture MM-151
An oligoclonal therapeutic composed of three fully human monoclonal antibodies targeting epidermal growth factor receptor (EGFR or ErbB1), with potential antineoplastic activity. Upon administration of MM-151, the three antibodies bind to distinct, non-overlapping epitopes of EGFR, thereby preventing the binding of a full range of both high and low affinity EGFR ligands and inhibiting EGFR-ERK-mediated signaling. This eventually inhibits tumor cell proliferation in EGFR-overexpressing tumor cells. Furthermore, multi antibody-antigen bindings cause crosslinking of EGFR and downregulate receptor signalings that are mediated via heterodimerization of EGFR with other members of the EGFR family. EGFR, a receptor tyrosine kinase overexpressed in a variety of cancer cell types, is a key regulator of cancer cell proliferation, apoptosis, invasion, and metastasis. (NCI Thesaurus)
