A Study of BTX-A51 in People With Relapsed or Refractory Acute Myeloid Leukemia or High-Risk Myelodysplastic Syndrome
This is an open-label, dose escalation study to evaluate the safety, toxicity, and pharmacokinetics (PK) as well as preliminary efficacy of BTX-A51 capsules in participants with relapsed or refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS).
The study will be done in three parts. Part 1a (Monotherapy Dose Escalation) of this study is designed to determine the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of orally administered BTX-A51 in up to 35 participants who are evaluable for toxicity. Once the MTD is determined, it is planned that an a
