Summary
Brief summary
This is an open label study of the dose and duration of an orally administered lysine-specific demethylase 1 (LSD1) inhibitor, bomedemstat, in patients with high-risk acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS). Some participants may also receive all-trans retinoic acid (ATRA; also known as tretinoin and Vesanoid®) in combination with bomedemstat. This study investigates the following:

* The safety and tolerability of bomedemstat with and without ATRA
* The pharmacodynamic effect of different doses of bomedemstat and treatment durations, as well as bomedemstat administered in combination with ATRA
* The pharmacokinetics of bomedemstat with and without ATRA
