FDA: Pfizer Voluntarily Withdraws Cancer Treatment Mylotarg from U.S. Market

Pfizer Inc. today announced the voluntary withdrawal from the U.S. market of the drug Mylotarg (gemtuzumab ozogamicin) for patients with acute myeloid leukemia (AML), a bone marrow cancer. The company took the action at the request of the U.S. Food and Drug Administration after results from a recent clinical trial raised new concerns about the product’s safety and the drug failed to demonstrate clinical benefit to patients enrolled in trials.
