Mechanism of action

EU-Perjeta (pertuzumab) is a HER2-directed monoclonal antibody that prevents HER2 from binding to its ligands and forming active dimers with other HER receptors, thereby disrupting downstream signaling pathways that drive cancer cell proliferation. It is often used in combination with trastuzumab (Herceptin) and chemotherapy to enhance anti-tumor activity in HER2-positive breast cancers.
