Adcetris (brentuximab vedotin): Drug Safety Communication - Progressive Multifocal Leukoencephalopathy and Pulmonary Toxicity
Jan 13, 2012
Audience: Oncology, Hematology, and Neurology
ISSUE: FDA notified healthcare professionals that two additional cases of progressive multifocal leukoencephalopathy (PML), a rare but serious brain infection that can result in death, have been reported with the lymphoma drug Adcetris (brentuximab vedotin). Due to the serious nature of PML, a new Boxed Warning highlighting this risk has been added to the drug label.
In addition, a new Contraindication warning was added against use of Adcetris with the cancer drug bleomycin due to increased risk of pulmonary (lung) toxicity.
The signs and symptoms of PML may develop over the course of several weeks or months. They may include changes in mood or usual behavior, confusion, thinking problems, loss of memory, changes in vision, speech, or walking, and decreased strength or weakness on one side of the body.
BACKGROUND: Adcetris (brentuximab vedotin) is used to treat Hodgkin lymphoma and a rare lymphoma known as systemic anaplastic large cell lymphoma. At the time of Adcetris' approval in August 2011, one case of PML was described in the Warnings and Precautions section of the label.
RECOMMENDATION: Patients who develop any signs and symptoms of PML should notify their healthcare professional immediately. Healthcare professionals should hold Adcetris dosing if PML is suspected and discontinue Adcetris if a diagnosis of PML is confirmed. See the Data Summary in the Drug Safety Communication for additional information.
