The U.S. Food and Drug Administration today approved Mylotarg (gemtuzumab ozogamicin) for the treatment of adults with newly diagnosed acute myeloid leukemia whose tumors express the CD33 antigen (CD33-positive AML). The FDA also approved Mylotarg for the treatment of patients aged 2 years and older with CD33-positive AML who have experienced a relapse or who have not responded to initial treatment (refractory).
Mylotarg originally received accelerated approval in May 2000 as a stand-alone treatment for older patients with CD33-positive AML who had experienced a relapse. Mylotarg was voluntarily withdrawn from the market after subsequent confirmatory trials failed to verify clinical benefit and demonstrated safety concerns, including a high number of early deaths. Today’s approval includes a lower recommended dose, a different schedule in combination with chemotherapy or on its own, and a new patient population.
Common side effects of Mylotarg include fever (pyrexia), nausea, infection, vomiting, bleeding, low levels of platelets in the blood (thrombocytopenia), swelling and sores in the mouth (stomatitis), constipation, rash, headache, elevated liver function tests, and low levels of certain white blood cells (neutropenia). Severe side effects of Mylotarg include low blood counts, infections, liver damage, blockage of the veins in the liver (hepatic veno-occlusive disease), infusion-related reactions, and severe bleeding (hemorrhage). Women who are pregnant or breastfeeding should not take Mylotarg, because it may cause harm to a developing fetus or a newborn baby. Patients with hypersensitivity to Mylotarg or any component of its formulation should not use Mylotarg.
The prescribing information for Mylotarg includes a boxed warning that severe or fatal liver damage (hepatotoxicity), including blockage of veins in the liver (veno-occlusive disease or sinusoidal obstruction syndrome), occurred in some patients who took Mylotarg.
