Brief Summary

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.

Study Arms (2)

Arm A

EXPERIMENTAL

Randomization should be performed between days 60 and 90 after the day of allogeneic hematopoietic stem cell infusion (day 0 post-HCT). Participants allocated in this arm must take Gilteritinib 3 tablets (40 mg per tablet) daily in the morning, with continuous daily administration

Drug: Gilteritinib

Arm B

ACTIVE COMPARATOR

Randomization should be performed between days 60 and 90 after the day of allogeneic hematopoietic stem cell infusion (day 0 post-HCT). Participants allocated in this arm must take sorafenib 400 mg orally, twice daily (BID), with continuous administration

Drug: Sorafenib

Interventions

Gilteritinib DRUG

Randomization should be performed between days 60 and 90 after the day of allogeneic hematopoietic stem cell infusion (day 0 post-HCT). Participants allocated in this arm must take Gilteritinib 3 tablets (40 mg per tablet) daily in the morning, with continuous daily administration.

Arm A

Sorafenib DRUG

Randomization should be performed between days 60 and 90 after the day of allogeneic hematopoietic stem cell infusion (day 0 post-HCT). Participants allocated in this arm must take sorafenib 400 mg orally, twice daily (BID), with continuous administration

Arm B
