Margetuximab, sold under the brand name Margenza, is a chimeric IgG monoclonal antibody medication against HER2 used for the treatment of cancer.[3][4]

The most common adverse drug reactions in combination with chemotherapy are fatigue/asthenia, nausea, diarrhea, vomiting, constipation, headache, pyrexia, alopecia, abdominal pain, peripheral neuropathy, arthralgia/myalgia, cough, decreased appetite, dyspnea, infusion-related reactions, palmar-plantar erythrodysesthesia, and extremity pain.[2]

This drug was created by Raven biotechnologies, which was later acquired by MacroGenics. It was engineered to increase affinity for CD16A polymorphisms and decrease affinity for FcγRIIB (CD32B), an inhibitory receptor.[4]

It binds to the same target (epitope) as trastuzumab,[5] on the HER2 receptor.
