New drug cocktail aims to stop leukemia return after transplant

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Participants must meet all of the following criteria to be eligible for enrollment in this study: 1. Diagnosed with acute myeloid leukemia (AML), excluding acute promyelocytic leukemia, according to the WHO 2022 classification, and without FLT3-ITD or FLT3-TKD mutations. 2. Presence of at least one of the following high-risk features: 1\) Adverse-risk AML according to the ELN 2022 risk classification; 2) Refractory AML; 3) Relapsed AML; 4) Persistent measurable residual disease positivity prior to transplantation; 5) Secondary AML transformed from myelodysplastic syndrome or myeloproliferative neoplasm. 3\. Undergoing first allogeneic hematopoietic stem cell transplantation (allo-HSCT). 4\. Stable hematologic recovery, defined as: Absolute neutrophil count ≥ 1.0 × 10⁹/L without G-CSF support; and Platelet count ≥ 50 × 10⁹/L without platelet transfusion within 7 days prior to randomization. 5\. Age ≥18 years and ≤75 years. 6. Eastern Cooperative Oncology Group performance status of 0-2. 7. Ability to provide written informed consent before initiation of any study procedures. 8\. Written informed consent may be provided by the participant or an authorized immediate family member in accordance with local regulations. Exclusion Criteria: Participants meeting any of the following criteria will be excluded from the study: 1. Evidence of disease relapse or impending relapse prior to randomization after transplantation, as determined by morphologic assessment or flow cytometry. 2. Active or uncontrolled acute graft-versus-host disease (aGVHD) requiring systemic immunosuppressive therapy. 3. Uncontrolled active infection requiring systemic antibacterial, antifungal, or antiviral therapy within 7 days prior to enrollment. 4. Moderate or severe hepatic impairment, as defined by the Child-Pugh classification. 5. Severe renal impairment, defined as creatinine clearance \<30 mL/min (calculated using the Cockcroft-Gault formula) or requirement for dialysis. 6. Pregnancy, or unwillingness/inability to use adequate contraception during the study treatment period. 7. Psychiatric disorders or other medical conditions that, in the investigator's judgment, would interfere with compliance with study treatment, monitoring, or study procedures.
