Post-transplant azacitidine plus chidamide to prevent relapse in high-risk acute myeloid leukemia

Official title: To Evaluate Safety and Efficiency of AZA Combined With Chidamide as Maintenance Therapy in High-risk Acute Myeloid Leukemia Patients After Allogeneic Hematopoietic Stem Cell Transplantation:A Multicenter, Single-arm Study

Run by Zhujiang Hospital · NCT05270200 · Data updated 2026-11-12

This tests whether giving azacitidine together with chidamide after an allogeneic stem-cell transplant can help prevent relapse in adults (18–60) with high‑risk acute myeloid leukemia.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–60 with non‑M3 AML who are high‑risk (poor genetics, primary refractory, relapsed, or secondary) after an allogeneic stem-cell transplant, with adequate organ function and blood counts, are the intended participants.

Probably not a fit

Patients with M3 AML, ongoing severe transplant complications or non-hematologic toxicity above Grade 2, persistent severe cytopenias, or those who cannot meet the blood‑count or organ‑function thresholds are unlikely to benefit or may be ineligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-arm Phase 1/2 trial giving six 28-day courses of subcutaneous azacitidine (days 1–3 each cycle) combined with daily oral chidamide starting about 30 days after allogeneic stem-cell transplant, continuing chidamide for up to two years. Participants must have recovered blood counts to specified thresholds before starting and will stop treatment for severe cytopenias or grade 3–4 non-hematologic adverse events. Monthly visits include routine blood and urine tests, with bone marrow aspirates at months 1,2,3,4,5,6,9 and 12 and ECGs every three months. The study is designed to collect safety data and signals of relapse prevention in high‑risk AML post-transplant.

Why it matters

Potential benefit: If successful, this regimen could reduce post-transplant relapse and extend relapse-free survival for high‑risk AML patients.

How similar studies have gone: Maintenance azacitidine after allo-HSCT has shown mixed but sometimes promising results in reducing relapse, while combining azacitidine with the HDAC inhibitor chidamide is a newer approach with limited prior clinical data.
