Insights

FMS-like tyrosine kinase 3 (FLT3) mutations are common in acute myeloid leukemia (AML). This review details FLT3 inhibitors, including midostaurin and gilteritinib, for managing FLT3-mutated AML.

Area of Science:

  • Hematology
  • Oncology
  • Molecular Biology

Background:

  • FMS-like tyrosine kinase 3 (FLT3) mutations are prevalent genetic alterations in acute myeloid leukemia (AML), found in about 30% of newly diagnosed cases.
  • These mutations are particularly common in AML patients with normal karyotypes.

Purpose of the Study:

  • To review clinically available FMS-like tyrosine kinase 3 (FLT3) inhibitors for treating acute myeloid leukemia (AML) with FLT3 mutations.
  • To summarize current and emerging treatment strategies for FLT3-mutated AML.

Main Methods:

  • Literature review of clinical trials and practice guidelines.
  • Analysis of data on FLT3 inhibitors in AML management.

Main Results:

  • Midostaurin is part of the standard induction chemotherapy (7+3) for newly diagnosed FLT3-mutated AML.
  • Gilteritinib demonstrates superior efficacy compared to salvage chemotherapy in relapsed or refractory FLT3-mutated AML.

Conclusions:

  • FLT3 inhibitors represent a significant advancement in the treatment of FLT3-mutated AML.
  • Ongoing research is expanding therapeutic options for patients with FLT3-mutated AML, considering disease status and patient factors.
