Clinical Trial Summary

To investigate the efficacy of interferon-α prophylaxis in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) with TP53 mutation who were negative for minimal residual disease (MRD) by flow cytometry within 2 months after allogeneic hematopoietic stem cell transplantation. To explore the efficacy of interferon-α in reducing the relapse rate of AML/MDS patients with TP53 mutation after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Intervention

Drug:
• IFN-?
Leukemia-associated immunophenotyping (LAIPs) was performed by flow cytometry at +1 month and +2 month after HSCT. If MRD was negative on two consecutive flow cytometry assays, interferon-a prophylaxis was initiated on day +75 after transplantation, and cyclosporine was tapered on day +100 after transplantation. The dose of interferon-a was 3 million units/time, subcutaneously injected twice a week. Cycles were given every 4 weeks until hematologic relapse or up to 6 cycles.
