Monoclonal antibody (biologic drug)
drug_description
Fc‑engineered humanized anti‑CD19 monoclonal antibody that targets CD19 on B cells and induces tumor cell death via ADCC, ADCP, and direct pro‑apoptotic effects; used here with lenalidomide for induction followed by tafasitamab monotherapy.

Tafasitamab
nci_thesaurus_definition
An Fc engineered, humanized anti-CD19 monoclonal antibody directed against the B-cell-specific membrane protein CD19 with potential immunostimulating and antineoplastic activities.Tafasitamab targets and binds to CD19, thereby depleting and eliminating CD19-expressing B-cells. The modified Fc region of XmAb5574 increases binding affinity to Fc-gamma receptors of effector cells and thereby enhances antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cell-mediated phagocytosis (ADCP). CD19 is widely expressed during B-cell development, from pro-B-cell to early plasma cell stages.
