Coprelotamab (GB221) is a humanized IgG1 monoclonal antibody targeting human epidermal growth factor receptor 2 (HER2/ERBB2), which effectively blocks receptor dimerization and downstream proliferative signaling by specifically binding to the HER2 extracellular domain IV. This antibody not only disrupts the malignant cell cycle but also possesses potent antibody-dependent cellular cytotoxicity (ADCC), enabling the precise elimination of HER2-overexpressing tumor lesions by recruiting immune effector cells.
