FDA Adds Boxed Warning to Two Cancer Drugs

By the Editors

The labels of the immune-suppressing, anti-cancer drugs ofatumumab (Arzerra) and rituximab (Rituxan) will be updated with a boxed warning noting an increased risk for reactivation of hepatitis B virus infection. Rituximab is used to treat non-Hodgkin lymphoma, and both drugs are used for chronic lymphocytic leukemia.

In its MedWatch safety alert, the FDA offers guidance for clinicians to help decrease the risk for HBV reactivation with these agents.
