About this trial

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.
