Naveen Pemmaraju, MD, University of Texas MD Anderson Cancer Center, Houston, TX, talks on the use of tagraxofusp in blastic plasmacytoid dendritic cell neoplasm (BPDCN) and other myeloid malignancies such as acute myeloid leukemia (AML), chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF). Tagraxofusp is a CD123-targeted agent originally approved for patients with BPDCN. Early-stage trials have recently shown that this agent appears to be safe and effective in both MF (NCT02268253) and CMML (NCT02268253) in the relapsed/refractory (R/R) setting and suggest that it should be further evaluated in clinical trials as a single agent or in different combinations. This interview took place at the 63rd ASH Annual Meeting and Exposition congress in Atlanta, GA.
