KDM1A and acute myeloid leukemia: The LSD1 inhibitors GSK2879552 and IMG-7289, alone or in combination with all-trans retinoic acid therapy (ATRA), showed promising activity against AML in vitro (Smitheman et al., 2019), leading to two ongoing phase I trials for patients with relapsed/refractory AML (NCT0217782, NCT02842827) and to a phase I/II trial for MDS patients (NCT02929498).
