Trastuzumab
nci_thesaurus_definition
A recombinant humanized monoclonal antibody directed against the human epidermal growth factor receptor 2 (HER2). After binding to HER2 on the tumor cell surface, trastuzumab induces an antibody-dependent cell-mediated cytotoxicity against tumor cells that overexpress HER2. HER2 is overexpressed by many adenocarcinomas, particularly breast adenocarcinomas. (NCI04)

drug_mechanism_of_action
Humanized IgG1 monoclonal antibody that binds the HER2 extracellular domain, blocking HER2 signaling and receptor dimerization, promoting receptor downregulation, and engaging Fcγ receptors to trigger antibody-dependent cellular cytotoxicity (ADCC), thereby suppressing PI3K/AKT and MAPK pathways in HER2-overexpressing tumor cells.
