Mechanism of action

Trastuzumab is a monoclonal antibody that binds to the HER2/neu receptor on cancer cells, which can help slow or stop the growth of these cells. Hyaluronidase is an enzyme that breaks down hyaluronic acid, a substance that can make it difficult for the drug to spread evenly throughout the body. By breaking down this substance, hyaluronidase helps the drug reach the cancer cells more effectively.
