Tafasitamab may cause serious side effects including infusion related reactions, bone marrow suppression, infections, and harm to an unborn baby.[2] The most common side effects of tafasitamab are low blood cell counts, fatigue, diarrhea, cough, fever, limb swelling, upper respiratory infection, and decreased appetite.[2]

Tafasitamab is a humanized Fc-modified cytolytic CD19 antibody.[1][3]

Tafasitamab was approved for medical use in the United States in July 2020.[2][3][4] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[5]

Medical uses

Tafasitamab, in combination with lenalidomide, is indicated for the treatment of adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).[1]

History

The FDA approved tafasitamab based primarily on evidence from one clinical trial (NCT02399085) of 81 participants 42 to 86 years old.[2] Participants in the trial had lymphoma that came back or did not improved after prior treatments.[2] The trial was conducted at 35 sites in the United States and Europe.[2] At first, participants received tafasitamab in combination with lenalidomide and later tafasitamab alone following a specific schedule during each 28-day treatment cycle.[2] Treatment continued until disease progression or unacceptable side effects.[2] Both participants and health care providers knew which treatment had been given.[2] The benefit of tafasitamab was evaluated by measuring how many participants had a complete or partial tumor shrinkage and how long that response lasted (called best overall response rate).[2]
