Gemtuzumab ozogamicin, sold under the brand name Mylotarg, is an antibody-drug conjugate (a drug-linked monoclonal antibody) that is used to treat acute myeloid leukemia (AML).
The most common side effects include infection, febrile neutropenia, decreased appetite, hyperglycemia, mucositis, hypoxia, hemorrhage, increased transaminase, diarrhea, nausea, and hypotension. However, the addition of gemtuzumab ozogamicin to standard chemotherapy regimens does not increase infection rates.
