What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
