Clinical Pearls

- 25-30% of patients with AML with normal karyotype will have activating mutations in FLT3.
- Sorafenib has shown activity in FLT3/ITD-positive AML.
- Quizartinib has shown high response rates as monotherapy, though data have shown responses tend to be mostly complete remissions with incomplete blood count recovery.
- Quizartinib may be an important agent to bridge patients to an allogeneic stem cell transplant, which would be the only curative option for patients with relapsed FLT3/ITD-positive AML.
- Patients who respond to quizartinib can develop a D835 mutation, but an agent is being developed that is active against both FLT/ITD and D835 mutations.
