The U.S. Food and Drug Administration today approved Perjeta (pertuzumab), a new anti-HER2 therapy, to treat patients with HER2-positive late-stage (metastatic) breast cancer.
Intended for patients who have not received prior treatment for metastatic breast cancer with an anti-HER2 therapy or chemotherapy, Perjeta is combined with trastuzumab, another anti-HER2 therapy, and docetaxel, a type of chemotherapy.
HER2 is a protein involved in normal cell growth. It is found in increased amounts on some types of cancer cells (HER2-positive), including some breast cancers. In these HER2-positive breast cancers, the increased amount of the HER2 protein contributes to cancer cell growth and survival.
Perjeta is a humanized monoclonal antibody, manufactured through biotechnology methods. It is administered intravenously and is believed to work by targeting a different part of the HER-protein than trastuzumab, resulting in further reduction in growth and survival of HER2-positive breast cancer cells.
