NAC for Hematopoietic Recovery in Low/Intermediate-Risk AML After CR: A Randomized Controlled Study

Sponsor: Peking University People's Hospital

Summary

This prospective, single-center, randomized controlled clinical trial aims to evaluate whether N-acetyl-L-cysteine (NAC) can promote hematopoietic recovery after chemotherapy in patients with acute myeloid leukemia (AML), and to explore its effects on disease remission and bone marrow microenvironment. Eligible participants are newly diagnosed low- or intermediate-risk AML patients aged 18-65 years, with no severe organ dysfunction or active infection. After completing induction chemotherapy with the HAA regimen, subjects will be randomly assigned in a 1:1 ratio to receive either NAC (400 mg orally three times daily for 28 days) plus standard care (intervention group) or standard care alone (control group). A total of 180 patients will be enrolled, with 90 patients in each group. The primary endpoint is the time to platelet recovery, defined as the number of days from the first day of chemotherapy until the first day that platelet count reaches ≥20×10⁹/L and remains stable for 7 consecutive days without transfusion support. Secondary endpoints include time to neutrophil recovery, total dose of G-CSF administered, total volume of red blood cell and platelet transfusions, complete remission rate, relapse-free survival, overall survival, and adverse events. The primary efficacy analysis will be performed in the intention-to-treat (ITT) population. Continuous variables will be compared between groups using the Mann-Whitney U test or paired t-test as appropriate. Safety will be assessed by the incidence and severity of adverse events. All statistical analyses will be conducted using SPSS 22.0, R software, and GraphPad Prism 8. The study is planned to last 3 years to evaluate treatment response and long-term outcomes of patients.
