Tafasitamab, sold under the brand name Monjuvi, is an anti-cancer medication used in combination with lenalidomide for the treatment of adults with diffuse large B-cell lymphoma; or, when used in combination with lenalidomide and rituximab, for the treatment of follicular lymphoma. Tafasitamab is a humanized Fc-modified cytolytic CD19 antibody.

Tafasitamab may cause serious side effects including infusion related reactions, bone marrow suppression, infections, and harm to an unborn baby. The most common side effects of tafasitamab are low blood cell counts, fatigue, diarrhea, cough, fever, limb swelling, upper respiratory infection, and decreased appetite.

Tafasitamab was approved for medical use in the United States in July 2020, and in the European Union in August 2021. The US Food and Drug Administration (FDA) considers it to be a first-in-class medication.
