About this trial

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).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Myelodysplastic syndrome (MDS) diagnosed according to the 2022 International Consensus Classification of Myeloid Neoplasms and Acute Leukemia (2022ICC) criteria, acute myeloid leukemia (AML) with TP53 mutation (unrestricted remission status), minimal residual disease (MRD) monitored by flow cytometry within 2 months after receiving the first allogeneic hematopoietic stem cell transplantation Negative patients

Male or female, aged 12-65 years

Karnofsky score >60, estimated survival time >3 months

Absolute neutrophil count (ANC) greater than 0.5×109/L

Disqualifiers

severe cardiac, renal, or liver dysfunction

combined with other malignant tumors requiring treatment

inability to understand or adhere to the study protocol due to clinical symptoms of brain dysfunction or severe mental illness

patients who are unable to complete the necessary treatment plan and follow-up observation

Trial design

Design model

Single group

Treatments tested in this trial

  • IFN-Α

    Drug

    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-α prophylaxis was initiated on day +75 after transplantation, and cyclosporine was tapered on day +100 after transplantation. The dose of interferon-α was 3 million units/time, subcutaneously injected twice a week. Cycles were given every 4 weeks until hematologic relapse or up to 6 cycles.

Trial outcomes

Primary outcomes

1

The incidence of relapse

Disease relapse was defined as blasts ≥ 5% post transplantation.

Time frame
1 year post HSCT

Secondary outcomes

1

The incidence of positive minimal residual disease post allo-HSCT

Positive MRD was defined as leukemia-associated immunophenotyping (LAIPs) by flow cytometry.

Time frame
1 year post HSCT
2

The incidence of acute and chronic graft versus host disease (GvHD)

The severity of acute GvHD (aGvHD) and chronic GvHD (cGvHD) was evaluated according to standard criteria.

Time frame
aGvHD within 100 days and cCvHD within 1 year
3

The incidence of non-relapse mortality

The incidence of non-relapse mortality

Time frame
1 year post HSCT.
4

The probability of progression free survival

Survival without disease progression

Time frame
1 year post HSCT.
