HERCLON Trastuzumab is one of a group of cancer drugs called monoclonal antibodies. Monoclonal antibodies are sometimes called targeted therapies because they work by ‘targeting’ specific proteins (receptors) on the surface of cells. Some cancers have too much of a protein called human epidermal growth factor receptor 2 (HER2) on the surface of their cells. These are called HER2-positive cancers. The extra HER2 receptors stimulate the cancer cells to divide and grow. Trastuzumab locks on to the HER2 protein and blocks the receptor. This stops the cells from dividing and growing.
