Summary

To explore the efficacy and safety ofblinatumomab± TKI in B-ALL patients aged ≥ 14 years with NGS-MRD relapse (sensitivity: 10-6) after auto/allo HSCT, and to observe the disease-free survival (DFS), recurrence rate and toxicity after transplantation.

Detailed description

To explore the efficacy and safety ofblinatumomab± TKI in B-ALL patients aged ≥ 14 years with NGS-MRD relapse (sensitivity: 10-6) after auto/allo HSCT, and to observe the disease-free survival (DFS), recurrence rate and toxicity after transplantation. Primary endpoint: disease-free survival (DFS), recurrence rate Secondary endpoints: NGS-MRD response rate, overall survival (OS), incidence of acute and chronic GVHD, and summary and evaluation of physical examination, vital signs, adverse events, concomitant treatments, and laboratory abnormalities. * Ph-negative B-ALL: bephedolumab (≥ 45 kg: 9 mcg/d D1-2, 28 mcg/d D3-14 or 28 mcg/d D1-14; \< 45 kg: 5 mg/m2/d D1-2, 15 mg/m2/d D3-14) in 28-day cycles for 3 cycles. * Ph-positive B-ALL: treatment with bephytoin + TKIs, bephytoin (≥ 45 kg: 9 mcg/d D1-2, 28 mcg/d D3-14 or 28 mcg/d D1-14; \< 45 kg: 5 mg/m2/d D1-2, 15 mg/m2/d D3-14) in 28-day cycles for 3 cycles. * Premedication with dexamethasone: 3)For adults, premedication with dexamethasone 20 mg was administered 1 hour prior to the first dose of each cycle ofblinatumomab, prior to dose escalation (eg, Cycle 1 Day 8), and when the infusion was restarted 4 hours or more after treatment interruption. 4)Pediatric patients were pre-treated with dexamethasone 5 mg/m2 up to a maximum of 20 mg prior to the first dose ofblinatumomabduring Cycle 1, prior to dose escalation (eg, Cycle 1 Day 8), and when the infusion was resumed 4 hours or more after interruption of therapy during Cycle 1.
