Bintrafusp alfa (M 7824) is a first-in-class bifunctional fusion protein composed of the extracellular domain of TGF-βRII fused to a human IgG1 mAb blocking programmed cell death ligand. Bintrafusp alfa can be used for the research of cancer.
Bintrafusp alfa can confer long-term protective immunity, decrease regulatory T-cell function, substantially increase CD8+ T cell and natural killer cell infiltration, and decrease myeloid-derived suppressor cell infiltration within tumors[1].
