Blinatumomab, a CD19\u002FCD3 bispecific T-cell engager, has shown promising efficacy in eradicating MRD and prolonging survival in B-ALL patients. In this study, eligible participants will be randomly assigned to receive either short-term blinatumomab consolidation prior to allo-HSCT or proceed directly to allo-HSCT. The primary endpoint is relapse-free survival (RFS). This study aims to optimize treatment strategies and improve long-term outcomes for patients with high-risk BCR::ABL1-negative B-ALL.",[27],"Acute Lymphoblastic Leukemia, B-precursor",[29,30,31,32],"allogeneic hematopoietic stem cell transplantation","measurable residual disease","Blinatumomab","high-risk BCR::ABL1-negative","RECRUITING","2026-08-31",{"date":36,"type":37},"2026-09-02","ACTUAL",{"date":39,"type":37},"2025-02-05",{"date":41,"type":21},"2028-02-05",{"name":43,"class":44},"First Affiliated Hospital of Zhejiang University","OTHER"]
