Influence of Co-existing Mutations on Sorafenib Maintenance Therapy After Allogeneic Hematopoietic Stem Cell Transplantation for Patients With FLT3-ITD Positive Acute Myeloid Leukemia

The purpose of this study is to reveal the influence of co-existing mutations on the efficacy of sorafenib maintenance after allogeneic hematopoietic stem cell transplantation for patients with FLT3-ITD AML.

Detailed Description

Internal tandem duplication of FMS-like tyrosine kinase 3 (FLT3-ITD) mutations have been reported in 20%-30% of patients with acute myeloid leukemia (AML). FLT3-ITD-positive AML patients have an inferior survival, primarily due to lower complete remission (CR) rate and higher relapse rate. Our previous studies demonstrated that post-transplantation sorafenib maintenance could improve the outcomes of FLT3-ITD-positive AML patients. However, whether other co-existing mutations influence the efficacy of post-allo-HSCT sorafenib maintenance remains unknown.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Sorafenib group
Patients assigned to this group received sorafenib post-transplantation.
Drug: Sorafenib
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).
Other Names:
  • BAY 43-9006
  • Nexavar
  • BAY-673472
  • BAY 545-9085
Control group
Patients assigned to this group did not receive sorafenib or any other FLT3 inhibitor post-transplantation until reaching the primary outcome.
