Phesgo is a combination prescription drug approved by the U.S. Food and Drug Administration (FDA) for use with chemotherapy to treat adults with early-stage HER-2 positive breast cancer. Phesgo is also approved for use with docetaxel to treat people with HER-2 positive metastatic breast cancer who haven’t received previous chemotherapy or anti-HER2 therapy. Phesgo is also referred to by the drug names of its components: pertuzumab, trastuzumab, and hyaluronidase-zzxf.

Phesgo is used as a targeted therapy for breast cancer. Phesgo is a combination of drugs belonging to the class of drugs called HER2/neu receptor antagonists. Phesgo is believed to work by binding to cancer cells, stopping cell growth, and causing cell death.
