Brief Summary

Allogeneic hematopoietic cell transplantation (Allo-HSCT) is an effective therapy for acute leukemia, but relapse is the most common problem affecting long-term survivors of allo-HSCT. Therapy options for relapse include stopping immune suppression, re-induction of chemotherapy, donor lymphocyte infusion (DLI) or combination therapy. In this prospective randomized controlled study, the safety and efficacy of hypomethylating agents (HMA) + DLI and DLI preemptive therapy based on minimal residual disease in acute leukemia undergoing allo-HSCT are evaluated.

    Relapse was defined by reappearance of blasts in the peripheral blood, recurrence of BM blasts \>5%, or development of extramedullary disease infiltrates at any site

    2 years

Secondary Outcomes (5)

  • Disease-free survival (DFS)

    2 years

  • Overall survival (OS)

    2 years

  • Transplant-related mortality (TRM)

    2 years

  • Incidence of acute GVHD

    100 days

  • Incidence of chronic GVHD

    2 years

Study Arms (2)

HMA+DLI

EXPERIMENTAL

For AL patients who achieved CR at pre-transplantation undergoing allo-HSCT, DLI was not given and immunosuppressant were withdrawn if patients were MRD persistently negative. MRD status were monitored every 30 days. If patients were MRD negative by Day+30 post-transplantation, MRD status would be continued to be monitored by Day+60. If patients were MRD positive by Day+30 post-transplantation, immunosuppressant were withdrawn. If MRD were persistently positive until Day+60 or MRD changed from negative by Day+30 to positive by Day +60 post-transplantation, HMA and DLI were given. DLI was given 48 hours after administration of HMA. DLI was given monthly until GVHD occurred or MRD became negative or a total of four times. If MRD changed from positive by Day+30 to negative by Day+60 post-transplantation, MRD status would be continued to be monitored by Day+90 post-transplantation. If patients were MRD positive by Day+90 post-transplantation, HMA and DLI were given as shown above.

Combination Product: HMA+DLI

DLI

MRD status were monitored every 30 days. If patients were MRD negative by Day+30 post-transplantation, MRD status would be continued to be monitored by Day+60 post-transplantation. If patients were MRD positive by Day+30 post-transplantation, immunosuppressant were withdrawn. If MRD were persistently positive until Day+60 or MRD changed from negative by Day+30 to positive by Day+60 post-transplantation, DLI was given.

If MRD changed from positive by Day+30 to negative by Day+60 post-transplantation, MRD status would be continued to be monitored by Day+90 post-transplantation. If patients were MRD positive by Day+90 post-transplantation, DLI was given as shown above.
