About this trial
The goal of this single-arm, prospective study is to test in low-burden B-cell lymphoblastic leukemia (B-ALL) patients undergoing allogeneic hemopoietic stem-cell transplantation (allo-HSCT). The main question it aims to answer is:
• The efficacy and safety of short-term blinatumomab as a bridging therapy to allo-HSCT in patients with low-burden B-ALL. Participants will take intravenous blinatumomab prior to allo-HSCT with an initial dosage of 8 μg/day. The dosage gradually escalated to 28 μg/day and continued for 5 to 10 days. Dexamethasone 20mg was administered 1 hour before the onset of blinatumomab infusion.
Eligibility criteria
Qualifiers
