Tafasitamab is a CD19-directed cytolytic monoclonal antibody used in the treatment of B-cell malignancies.
The CD19 surface antigen is a protein expressed on the surface of pre-B and mature B-lymphocytes that appears to play a role in enhancing B-cell receptor signaling and is considered integral to their survival. These surface proteins are also highly expressed on several B-cell malignancies, such as chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and diffuse large B-cell lymphoma (DLBCL). Tafasitamab is a CD19-directed cytolytic monoclonal antibody that, upon binding and blocking the activity of CD19, causes lysis of B-cells. This process is mediated through both direct apoptosis and immune-mediated effector mechanisms, such as antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).
Tafasitamab is indicated, in combination with lenalidomide, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified whom are ineligible for autologous stem cell transplant (ASCT).
