What is Margenza?

Margenza is an FDA (U.S. Food and Drug Administration) approved monoclonal antibody manufactured by MacroGenics, Inc. Approval was based on safety and efficacy results from the pivotal Phase 3 Sophia trial. The study showed a significant 24% reduction in the risk of disease progression or death with Margenza with chemotherapy (capecitabine, eribulin, gemcitabine, or vinorelbine) compared to trastuzumab with chemotherapy.

MARGENZA is a HER2/neu receptor antagonist indicated, in combination with chemotherapy, for the treatment of 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.

What doses of Margenza are available?

Margenza is available in injection form, in the following doses: 250 mg/10 mL (25 mg/mL) in a single-dose vial.

Before starting therapy, you should have an echocardiogram or a MUGA (multigated blood-pool imaging) scan to check how well your heart is functioning.

Administer Margenza as an intravenous infusion at 15 mg/kg over 120 minutes for the initial dose, then over a minimum of 30 minutes every 3 weeks for all subsequent doses. Margenza may be administered immediately after chemotherapy completion on days when both Margenza and chemotherapy are to be administered.

Please see the full prescribing information for the complete boxed warning and always speak with a healthcare professional for medical advice about any changes to your dose so they can monitor and evaluate your condition.
