Trastuzumab binds to the extracellular domain of HER2/erbB2 (human epidermal growth factor receptor 2), which is overexpressed in certain malignancies. Trastuzumab helps to mediate antibody-dependent cellular cytotoxicity (ADCC) preferentially against cells that overexpress HER2.
Route: IV
Extravasation: neutral
