FDA Approves MacroGenics’ Margenza
FDA has approved MacroGenic’s Margenza (margetuximab-cmkb), in combination with chemotherapy, to treat adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease.
A company statement says Margenza is the first HER2-targeted therapy to have improved progression-free survival versus Genentech’s Herceptin (trastuzumab), both combined with chemotherapy, in a head-to-head Phase 3 trial.
MicroGenics says the approval was based on safety and efficacy results from the Phase 3 SOPHIA trial and that Margenza will be available in 3/2021.
