SHR2554/AZA + Overlapped TBF for High-risk/Relapsed Leukemia/MDS

China160 participantsStarted 2026-06

Plain-language summary

This study was designed as a prospective, multicenter, open-label, randomized controlled trial. Eligible participants were patients aged 15-60 years with high-risk or relapsed/refractory acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic neoplasms (MDS), diagnosed based on bone marrow morphology, immunophenotyping, genetic testing, and treatment response assessment. The experimental group received SHR2554 combined with azacitidine as an overlapped sequential combination with the TBF conditioning regimen, whereas the control group received the mBuCy conditioning regimen, both followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). The primary endpoint was the 2-year cumulative incidence of relapse (CIR) after allo-HSCT. Secondary endpoints included 2-year overall survival (OS), 2-year disease-free survival (DFS), transplant-related mortality (TRM), the incidence of acute and chronic graft-versus-host disease (GVHD), and safety profiles.

Inclusion criteria

✓. Age 15-60 years, of either sex.
✓. Diagnosis of AML or ALL according to the WHO 2022 criteria, with an indication for allogeneic hematopoietic stem cell transplantation: AML with high-risk genetics at diagnosis (risk stratification per ELN 2022) or relapsed/refractory AML (meeting any of the following: refractory-failure to achieve complete remission (CR) after two cycles of induction chemotherapy; relapse-reappearance of blasts in peripheral blood or bone marrow (≥5%) after first CR, or extramedullary relapse (EMR)). High-risk B-ALL at diagnosis (risk stratification per ELN 2022) or pre-transplant MRD-positive B-ALL. Confirmed T-ALL. History of central nervous system leukemia (CNSL) or pathologically confirmed extramedullary disease (EMD) during AML or ALL. Myelodysplastic neoplasms (MDS): IPSS score intermediate-2 or high; IPSS-R score high or very high; IPSS-M score high or very high.
✓. Availability of an appropriate HLA-matched donor.
✓. ECOG performance status 0-2.
✓. Adequate major organ function, defined as: Left ventricular ejection fraction ≥50%. Pulmonary function: DLCO ≥50% of predicted value. Liver function: ALT/AST ≤3×ULN, total bilirubin ≤2×ULN. Renal function: estimated creatinine clearance (CrCl) ≥60 mL/min.
✓. Ability to understand the study and voluntary signed informed consent.
