Enhertu

A drug used to treat adults with HER2-positive breast cancer that cannot be removed by surgery or has spread to other parts of the body. It is used in patients who have already received at least two anti-HER2 treatments for metastatic disease. It is also being studied in the treatment of other types of cancer. Enhertu contains a monoclonal antibody called trastuzumab that binds to a protein called HER2, which is found on some breast cancer cells. It also contains an anticancer drug called deruxtecan, which may help kill cancer cells. Enhertu is a type of antibody-drug conjugate. Also called fam-trastuzumab deruxtecan.
