Description

Summary

Study BH-30236-01 is a first-in-human (FIH), Phase 1/1b, open-label, dose escalation and expansion study in participants with relapsed/refractory acute myelogenous leukemia (R/R AML) or higher-risk myelodysplastic syndrome (HR-MDS).

Phase 1, Part 1 Dose Escalation - Monotherapy will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of BH-30236 administered orally. Approximately 50 participants may be enrolled in Phase 1, Part 1 Dose Escalation - Monotherapy.

Phase 1, Part 2 Dose Escalation - Combination with Venetoclax will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of BH-30236 administered as a combination therapy with venetoclax. Approximately 48 participants may be enrolled in Phase 1, Part 2 Dose Escalation - Combination with Venetoclax.

Phase 1b (Dose Expansion) will follow Phase 1 to further understand the relationships among dose, exposure, toxicity, tolerability, and clinical activity. Up to 72 participants may be enrolled in Phase 1b of the study as a monotherapy or in combination with venetoclax.

Official Title

A Phase 1/1b Open-Label, Dose Escalation, First-in- Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Anti-leukemic Activity of the Orally Available CDC-Like Kinase (CLK) Inhibitor, BH-30236, in Adults With Relapsed or Refractory Acute Myelogenous Leukemia (R/R AML) or Higher-Risk Myelodysplastic Syndrome (HR-MDS)

Details

This is a Phase 1/1b, multi-center, open-label, dose escalation, first-in-human study to evaluate the safety, tolerability, PK, PD, and preliminary anti-leukemic activity of the CLK inhibitor, BH-30236 as a monotherapy or in combination with venetoclax, in adult participants with R/R AML or HR-MDS.

The study consists of three parts: Phase 1, Part 1 Dose Escalation - Monotherapy, Phase 1, Part 2 Dose Escalation - Combination with Venetoclax, and Phase 1b Dose Expansion.

Phase 1, Part 1 Dose Escalation - Monotherapy is anticipated to enroll approximately 50 participants to evaluate the safety, tolerability, PK, PD, and preliminary anti-leukemic activity of BH-30236, as well as determine the MTD and/or the preliminary recommended dose(s) for expansion (RDEs).

Phase 1, Part 2 Dose Escalation - Combination with Venetoclax is anticipated to enroll approximately 48 participants to evaluate the safety, tolerability, PK, PD, and preliminary anti-leukemic activity of BH-30236, as well as determine the MTD and/or the preliminary recommended dose(s) for expansion (RDEs).

Phase 1 will follow a Bayesian optimal interval (BOIN) design dose escalation, where participants will receive ascending doses of BH-30236 to determine the recommended RDEs.

Phase 1b Dose Expansion will enroll approximately 72 participants to evaluate the safety, tolerability, and preliminary anti-leukemic activity of BH-30236 as a monotherapy or in combination with venetoclax at selected RDEs determined in Phase 1 Dose Escalation.

Eligibility

You can join if…

Open to people ages 18 years and up

  • ≥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.

You CAN'T join if...

  • 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.
