A Study of BH-30236 in Relapsed/ Refractory Acute Myelogenous Leukemia and Higher Risk Myelodysplastic Syndrome
brief 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.
detailed description
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.
