Herceptin (trastuzumab)
Herceptin, the brand name for trastuzumab, is a monoclonal antibody used as a targeted therapy for certain types of breast and stomach cancers. It specifically targets the human epidermal growth factor receptor 2 (HER2), a protein that can promote the growth of cancer cells. Trastuzumab works by binding to the HER2 protein, inhibiting the proliferation of cancer cells that overexpress this receptor.
