New pill combo aims to improve AML treatment in Non-FLT3 patients
NCT ID NCT04107727
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tested whether adding the targeted drug quizartinib to standard chemotherapy helps adults with newly diagnosed acute myeloid leukemia (AML) that does not have a FLT3 mutation. 273 patients were randomly assigned to receive either quizartinib or a placebo alongside their chemo. The study looked at how long patients stayed free of leukemia-related events and how well they tolerated the treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Quizartinib (a targeted cancer drug taken as a pill)
- What this could lead to
- If successful, this could provide a new treatment option for people with a common type of AML that lacks the FLT3 mutation.
- What could go wrong
- This is a phase 2 trial, so results are still early. The drug may not improve outcomes or could cause side effects. It is also tested only in a specific genetic subgroup.
