Allogeneic Hematopoietic Cell Transplantation (HCT)

The study population consisted of FLT3-ITD-mutated AML patients who were FLT3-ITD-positive before allogeneic hematopoietic stem cell transplantation. This open-label, randomized, controlled trial enrolled participants and randomly assigned them in a 1:1 ratio to either the experimental group or the control group. The experimental group received maintenance therapy with gilteritinib, while the control group received maintenance therapy with sorafenib, with 297 cases in each group, totaling 594 enrolled subjects. All patients' minimal residual disease (MRD) testing was sent to the designated central laboratory and uniformly performed using the PCR-NGS method to ensure consistency and comparability of the test results. Study Visits: This study includes a screening period (within 30 days prior to HCT) and a 2-year treatment phase, with efficacy and safety follow-up until death, withdrawal of informed consent, or 2 years after the first administration of treatment, whichever occurs first.

This study is a Phase II clinical trial designed to evaluate the efficacy and safety of Chidamide as maintenance therapy in high-risk acute myeloid leukemia (AML) patients following stem cell transplantation. Trial Design: The trial is a single-arm, open-label study. The experimental group plans to enroll 67 patients, while the control group (observation only) also plans to enroll approximately 67 patients, with randomization. All patients must have received induction chemotherapy prior to enrollment and may or may not have received consolidation therapy. The chemotherapy regimen was determined by the treating physician. Patients had received induction and/or consolidation therapy, achieved remission, and underwent stem cell transplantation. Study Objectives: The study aims to assess the impact of Chidamide maintenance therapy on recurrence-free survival (RFS), overall survival (OS), and the duration of complete remission. The study will also evaluate the tolerability and toxicity profile of this regimen, as well as the effect of maintenance therapy on the dynamics of minimal residual disease (MRD).
