Interferon-α Maintenance in Favorable-Risk AML
Interferon-α as Maintenance Therapy for Favorable-Risk Acute Myeloid Leukemia: A Prospective, Single-Arm Study
Acute myeloid leukemia (AML) is a blood cancer with a substantial risk of relapse after initial treatment. Although patients with favorable-risk AML generally have better outcomes, relapse remains a major concern. Interferon-alpha (IFN-α) may help prevent relapse, but its effectiveness as maintenance therapy has not been confirmed in prospective studies.
This prospective, single-arm study aims to evaluate the efficacy and safety of IFN-α as maintenance therapy in patients with favorable-risk AML. Participants will receive IFN-α maintenance treatment and will be followed for disease relapse, survival, and treatment-related adverse events.

Experimental: Peginterferon Alfa-2b Maintenance Therapy
Eligible patients with favorable-risk acute myeloid leukemia (AML) in first complete remission (CR1) after consolidation chemotherapy will receive peginterferon alfa-2b injection at a dose of 135 μg once weekly by subcutaneous injection for 6 months. Participants will be monitored for disease relapse, measurable residual disease (MRD), survival, and treatment-related adverse events, with follow-up for 2 years after enrollment. |

Measure Description |
Time Frame |
|---|---|---|
|
2-Year Cumulative Incidence of Relapse
Time Frame: 2 years after enrollment
|
The proportion of patients who experience disease relapse within 2 years after enrollment. Relapse is defined as bone marrow blasts ≥5%, detection of leukemic cells in peripheral blood, or extramedullary leukemia. |
2 years after enrollment
|

|
2-Year Event-Free Survival (EFS)
Time Frame: 2 years after enrollment
|
Event-free survival is defined as the time from enrollment to the first occurrence of molecular progression, hematologic relapse, or death from any cause. |
2 years after enrollment
|
|
2-Year Overall Survival (OS)
Time Frame: 2 years after enrollment
|
Overall survival is defined as the time from enrollment to death from any cause. Participants who are alive at the last follow-up will be censored. |
2 years after enrollment
|
|
MRD Conversion Rate Among Patients With MRD-Positive Disease at Enrollment
Time Frame: Up to 2 years after enrollment
|
The proportion of patients with measurable residual disease (MRD)-positive status at enrollment who achieve MRD-negative status during follow-up, assessed by multiparameter flow cytometry and/or quantitative PCR. |
Up to 2 years after enrollment
|
|
Number of Participants With Grade 3 or Higher Adverse Events
Time Frame: During the 6-month maintenance treatment period
|
The number of participants experiencing grade 3 or higher adverse events during peginterferon alfa-2b maintenance therapy, including hematologic and hepatic toxicities. Adverse events will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. |
During the 6-month maintenance treatment period
