A Phase 1 Study With LYT-200 in Patients With Relapsed/Refractory Acute Myeloid Leukemia (AML), or With Relapsed/Refractory, High-risk Myelodysplastic Syndrome (MDS)

This is an open-label, non-randomized, multi-center, Phase 1, dose escalation study in patients with AML relapsed/refractory to at least one line of prior therapy, with or without an allogeneic stem cell transplant, or in patients with a documented diagnosis of relapsed/refractory, high-risk myelodysplastic syndrome (MDS) post at least one line of treatment and for whom no standard therapy that may provide clinical benefit is available. The 4+2 algorithm-based dose-escalation design will be used to help identify the recommended Phase 2 dose (RP2D). Single agent LYT-200 and in combination with venetoclax and/or hypomethylating agents (HMA) safety and tolerability evaluation is the primary study endpoint, Pharmacokinetics (PK), and Anti-tumor Activity of LYT- 200 single agent and in combination with venetoclax and/or HMAs are key secondary study endpoints.
