Researchers are studying bleximenib, an investigational drug taken orally, to find the best dose for treating acute leukemia and to evaluate its safety and effectiveness. In Phase 1, they aim to identify the recommended Phase 2 dose (RP2D) through a dose escalation and expansion process. Phase 2 will focus on assessing how well bleximenib works at the recommended dose in participants with relapsed or refractory acute leukemia, particularly those with specific genetic alterations in KMT2A, NPM1, or NUP98/NUP214. The study involves administering bleximenib orally and includes different participant groups based on age and disease status. Phase 1 includes pediatric participants aged 2 to less than 18 years and adults 18 years and older with relapsed or refractory acute leukemia who have limited treatment options. Phase 2 focuses on adults over 18 with relapsed or refractory acute myeloid leukemia harboring KMT2A or NPM1 mutations. The trial monitors participants for dose-limiting toxicities, adverse events, and treatment tolerability over periods lasting up to nearly five years. Participants will undergo evaluations of safety, including the number and severity of adverse events and dose-limiting toxicities during the first cycle. The effectiveness measure in Phase 2 is the rate of complete remission or remission with partial blood count recovery. Throughout the study, participants will be assessed using laboratory tests, performance status scales, and pregnancy tests as applicable. Safety monitoring and long-term follow-up will continue for up to 4 years and 9 months to fully evaluate treatment effects and tolerability.

Researchers are evaluating the combination of bleximenib, venetoclax (VEN), and azacitidine (AZA) compared to placebo with venetoclax and azacitidine alone in treating adults newly diagnosed with acute myeloid leukemia (AML) who have specific gene mutations (NPM1 or KMT2A) and are not eligible for intensive chemotherapy. This is a phase 3 randomized, double-blind, placebo-controlled study focusing on participants with AML harboring these genetic abnormalities. The study aims to assess treatment effectiveness by measuring complete remission rates and overall survival. Bleximenib and venetoclax are given orally, while azacitidine is administered either intravenously or under the skin. Participants will receive either the combination of bleximenib, venetoclax, and azacitidine or placebo with venetoclax and azacitidine, following a rigorous treatment schedule. The study includes an initial treatment period where the effects of these drugs are compared to determine their impact on AML with the given mutations. Participants will be closely monitored through regular assessments, including evaluations of remission status and survival over a period of up to 4 years and 1 month. Safety and treatment responses will be tracked throughout the study. Participants must consent to follow the study procedures and agree to contraception requirements during and after treatment. The trial involves continuous observation to gather comprehensive data on treatment outcomes and participant health.
