Sara Olalla Saad, PhD, University of Campinas & Hemocentro – Unicamp, Campinas, Brazil, discusses a novel chemical compound inhibitor of hematopoietic cell kinase (HCK). She explains how this was found to have antiproliferative activity in leukemic cells without altering the cell death and survival rate of normal cells, having a synergistic effect with azacitidine or cytarabine, for acute myeloid leukemia (AML), and discusses how they are moving testing of this agent forwards. This interview took place at the American Society of Hematology (ASH) 2019 Annual Meeting and Exposition in Orlando, FL.
