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.

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.

Inclusion criteria: * ≥18 years. * Diagnosis of relapsed/refractory acute myelogenous leukemia (R/R) AML or higher-risk myelodysplastic syndrome (HR-MDS) with ≥5% bone marrow blast at time of inclusion. * 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. * Renal: Measured or calculated creatinine clearance ≥ 60 mL/min (Cockcroft-Gault formula) The above are a summary, other inclusion criteria details may apply. Exclusion Criteria: * Diagnosis of acute promyelocytic leukemia or chronic myeloid leukemia with blast crisis. * Prior allogeneic HSCT within 3 months or donor lymphocyte infusion within 30 days of start of therapy; * Active and uncontrolled infections. * Unresolved AEs greater than Grade from prior therapies. * History of other active malignancy (with certain exceptions) * Prior treatment with a CLK inhibitor. * Any acute or chronic graft versus host disease requiring systemic therapy within 4 weeks prior to study drug administration with the exception of topical steroids or the equivalent of 20 mg of prednisone or less. The above is a summary, other exclusion criteria details may apply.
