Overview
Tagraxofusp is a CD123-directed cytotoxin and recombinant fusion protein composed of human interleukin-3 (IL-3) genetically fused to the catalytic and translocation domains of truncated diphtheria toxin. It is used for the treatment of blastic plasmacytoid dendritic cell neoplasm (BPDCN), a rare hematologic malignancy. Tagraxofusp binds with high affinity to the IL-3 receptor alpha chain (CD123) on target cells, is internalized via receptor-mediated endocytosis, and releases its diphtheria toxin component into the cytosol. The toxin irreversibly inhibits protein synthesis by inactivating elongation factor 2, leading to apoptosis of malignant cells. Tagraxofusp was first approved by the FDA in December 2018 as the first treatment for BPDCN and later received approval in Europe[2][4][5][7][8].
