This prospective trial investigates the effect of sorafenib maintenance therapy in FLT3-ITD AML patients after allo-HSCT in terms of gut microbiome.
Hematopoietic stem cell transplantation (HSCT) is used as a potentially curative therapy for patients with hematopoietic malignancies. Sorafenib, an inhibitor of multiple kinases including FLT3, has shown promising activity in FLT3-ITD-positive AML. Our previous studies demonstrated that sorafenib maintenance post-transplantation could improve the outcomes of FLT3-ITD-positive AML patients, which is associated with sorafenib enhancing the graft-versus-leukemia (GVL) effect. Recent studies show that gut microbiome is associated with graft-versus-host-disease (GVHD) and GVL. However, the exact mechanism of sorafenib enhancing the GVL effect and the influence of gut microbiome on sorafenib maintenance after allo-HSCT remain unknown.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| sorafenib group | FLT3-ITD+ AML patients who receive sorafenib maintenance therapy after Allo-HSCT. Sorafenib will be used from day 30 to 180 post-transplantation. The initial dose of sorafenib is 400 mg orally twice daily and is adjusted in case of suspected toxicity or resistance (dose range, 200-800 mg daily). |
| |
| non-sorafenib group | FLT3-ITD+ AML patients who do not receive sorafenib maintenance therapy after Allo-HSCT. |
| Name | Type | Description | Arm Group Labels | Other Names |

Stool, bone marrow and/or peripheral blood samples will be collected on the first day of regimen therapy for allo-HSCT, then subsequently every 28 days until discharging from the hospital, whichever occurs sooner. After discharging from the hospital, specimens will continuously be collected on the day before sorafenib maintenance therapy, then subsequently every 28 days until 3 months after receiving sorafenib maintenance therapy. The samples were tagged and stored at -80°C until retrieval for DNA extraction and cytokine detection.
