HUMAN ANTI CETUXIMAB

Human Anti-Cetuximab Antibody, clone AbD19376_hIgG1, is a non-inhibitory anti-idiotypic antibody that binds to cetuximab. This antibody recognizes an epitope outside the cetuximab binding site and so does not inhibit the binding of the drug to its target, epidermal growth factor receptor (EGFR). This epitope is shared with other chimeric antibodies that are highly homologous to cetuximab including infliximab but excluding rituximab. The antibody is suitable for the development of bioanalytical assays for cetuximab and biosimilars.Clone AbD19376_hIgG1 is a fully human recombinant monoclonal with IgG1 isotype and is suitable as a surrogate positive control or calibrator in an anti-drug antibody (ADA) assay. In addition, it is suitable as a detection antibody in pharmacokinetic (PK) bridging ELISA, with Anti-Cetuximab Antibody HCA220 as the capture antibody. This combination enables measurement of free and partially bound cetuximab, which is equivalent to total drug when trough serum levels are above 4 μg/ml.Cetuximab (brand name Erbitux) is a chimeric monoclonal antibody drug (IgG1/kappa) approved for treatment of KRAS wild-type metastatic colorectal cancers and squamous cell carcinoma of the head and neck. This therapeutic antibody is directed against EGFR and inhibits tumor cell proliferation by blocking the interaction of epidermal growth factor (EGF) with its receptor.View a summary of all anti cetuximab antibodies.
