What the trial is, and whether it could suit you
This is a prospective, multicenter, randomized controlled trial designed to evaluate the efficacy and safety of venetoclax-enhanced BUCY (Ven-BUCY) conditioning compared to the standard BUCY regimen in patients with high-risk acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Eligible participants aged 12 to 60 years will be randomized 1:1 to receive either Ven-BUCY or standard BUCY conditioning. The primary endpoint is relapse-free survival (RFS) at two years post-transplant. Secondary outcomes include overall survival, relapse rate, non-relapse mortality, measurable residual disease (MRD), and treatment-related adverse events. The study aims to improve post-transplant outcomes by deepening disease remission through the addition of venetoclax, a BCL-2 inhibitor known to target leukemia stem cells and
