About this trial
Allogeneic hematopoietic cell transplantation (allo-HCT) is the only treatment that offers a possible cure for relapsed/refractory AML. Currently, the optimal preallo-HCT bridging regimen for relapsed/refractory AML patients is unclear. Venetoclax-based regimens, including Venetoclax + demethylating agents (HMA) , Venetoclax + HMA + other drugs and Venetoclax-based multidrug combinations as a bridging regimen improves response rate and post-transplant survival in relapsed/refractory AML patients. Therefore, the investigators conduct a prospective single-centre clinical study to evaluate the efficacy and safety of VAH as a transplant bridging regimen for relapsed/refractory AML.
Eligibility criteria
Qualifiers
Aged 14 to 70 years (inclusive), regardless of gender;
The diagnosis of AML was confirmed on the basis of bone marrow cytomorphology, immunophenotyping and chromosomal and molecular biology tests;
Relapsed AML: After achieving complete remission (CR), the reappearance of leukemic cells in peripheral blood, or ≥5% blasts in bone marrow (excluding other causes such as bone marrow regeneration after consolidation chemotherapy), or extramedullary infiltration by leukemic cells.
With RUNX1::RUNX1T1 AML: Positive measurable residual disease (MRD) on bone marrow flow evaluation after the second consolidation therapy and/or less than a 3-log decrease in the RUNX1::RUNX1T1 fusion gene and diagnostic baseline values;
Disqualifiers
Allergies or contraindications to any of the drugs in the protocol;
