Abstract

Tagraxofusp (tagraxofusp-erzs) [Elzonris™] is an intravenously administered CD123-directed cytotoxin (composed of human interleukin-3 and a truncated diphtheria toxin payload) that was developed by Stemline Therapeutics, Inc. for the treatment of blastic plasmacytoid dendritic cell neoplasm (BPDCN). In December 2018, tagraxofusp received its first global approval in the USA for the treatment of BPDCN in adults and in paediatric patients aged 2 years and older. A centralized registration application for the use of tagraxofusp in patients with BPDCN is under review in the EU. This article summarizes the milestones in the development of tagraxofusp leading to its first global approval for the treatment of BPDCN.
