Overview
Margenza is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat adults with metastatic HER2-positive breast cancer who have received two or more prior therapies. Margenza may also be referred to by its drug name, margetuximab-cmkb.

Margenza is a HER2/neu receptor antagonist. Margenza is believed to fight breast cancer by blocking cancer cells from receiving signals that would tell them to grow.

Margenza comes in the form of an injectable suspension.
