Matuzumab is a humanized monoclonal antibody used in cancer treatment. It has a high affinity for EGFR (epithelial growth factor receptor), frequently associated with the growth of blood vessels in malignancy, facilitating tumor growth and survival.Matuzumab binds the epidermal growth factor receptor (EGFR) with high affinity, competitively blocking natural ligand binding and blocking receptor-mediated downstream signalling, resulting in impaired tumor cell proliferation. Matuzumab (EMD-72000) is a humanized IgG1 MAb that not only binds with high specificity and affinity to EGFR, but also modulates antibody-dependent cellular cytotoxicity (ADCC).
