In this interview, Daniel DeAngelo, MD, PhD, of Dana-Farber Cancer Institute, Boston, MA, discusses a novel therapeutic that is antagonistic towards E-selectin, GMI-1271. Dr DeAngelo discusses the rationale behind the mechanism of action of this drug and the results of the trial investigating this agent (NCT02306291), which he presented at the American Society of Hematology (ASH) 2017 Annual Meeting and Exposition in Atlanta, GA.
