Gemtuzumab ozogamicin (marketed by Wyeth as Mylotarg) is a monoclonal antibody used to treat acute myelogenous leukemia.

It is a monoclonal antibody to CD33 linked to a cytotoxic agent, calicheamicin. CD33 is expressed in most leukemic blast cells but also in normal hematopoietic cells the intensity diminishing with maturation.stem cells. When given to patients in first relapse, 15% of patients achieve a complete remission. In the United States, it was approved by the FDA for use in patients over the age of 60 with relapsed AML who are not considered candidates for standard chemotherapy.[1]

A notable complication of therapy with gemtuzumab is the increased risk of veno-occlusive disease in the absence of bone marrow transplantation.[2] The onset of VOD can also be delayed and can occur at increased frequency following bone marrow transplantation.[3]


Common side effects of administration include shivering, nausea, and fever. Serious side effects include severe myelosuppression (found in 98% of patients), disorder of the respiratory system, tumor lysis syndrome, and Immune hypersensitivity syndrome.
