Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with relapsed or refractory acute myelogenous leukemia or higher-risk myelodysplastic syndrome.

Probably not a fit

Patients with acute promyelocytic leukemia or chronic myeloid leukemia with blast crisis may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the safety and effectiveness of BH-30236, a CLK inhibitor, in adults with relapsed or refractory acute myelogenous leukemia (R/R AML) or higher-risk myelodysplastic syndrome (HR-MDS). The study is divided into two phases: Phase 1 focuses on dose escalation to determine the maximum tolerated dose and preliminary efficacy, while Phase 1b involves dose expansion to further assess safety and anti-leukemic activity at the recommended doses. Approximately 74 participants will be enrolled across both phases, with careful monitoring of pharmacokinetics and pharmacodynamics.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat forms of leukemia.

How similar studies have gone: While this approach is novel, similar studies targeting other forms of leukemia have shown promising results.

* Prior treatment history must include 1-5 prior lines of therapy.
* ECOG performance status ≤2.
* Adequate organ function evidenced by the following laboratory values:
* Hepatic: Transaminase levels aspartate aminotransferase \[AST\]/ alanine transaminase \[ALT\] ≤ 2.5 × upper limit of normal (ULN). In cases of liver involvement by AML or MDS, AST and ALT \< 5.0 × ULN is acceptable. Total bilirubin ≤ 1.5 × ULN in the absence of documented Gilbert's disease.
