FLT3-ITD is a constitutively activated variant of the FLT3 tyrosine kinase receptor. Its expression in acute myeloid leukemia (AML) is associated with a poor prognosis. Due to this, the development of tyrosine kinase inhibitors (TKI) blocking FLT3-ITD became a rational therapeutic concept. This review describes key milestones in the clinical development of different FLT3-specific TKI with a particular focus on FLT3-TKI maintenance therapy in remission after allogeneic hematopoietic stem cell transplantation (HCT). Recent evidence from randomized trials using sorafenib in FLT3-ITD mutated AML provided a proof of concept that targeted post-HCT maintenance therapy could become a new treatment paradigm in AML.
FLT3-ITD 是 FLT3 酪氨酸激酶受体的组成性激活变体。其在急性髓系白血病(AML)中的表达与预后不良相关。因此,开发阻断 FLT3-ITD 的酪氨酸激酶抑制剂(TKI)成为一种合理的治疗概念。本综述描述了不同 FLT3 特异性 TKI 临床开发的关键里程碑,特别关注异基因造血干细胞移植(HCT)后缓解期的 FLT3-TKI 维持治疗。最近使用索拉非尼治疗 FLT3-ITD 突变 AML 的随机试验提供了证据,证明针对移植后维持治疗可能成为 AML 的一种新治疗模式。
