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 This study
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
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Doctors often wait days for genetic tests to classify acute myeloid leukaemia (AML) and guide treatment. This trial tests whether breath analysis can detect metabolic products from leukaemia and classify the disease faster. Participants give breath samples and extra blood tests during their first two treatment cycles, coordinated with routine hospital visits. Researchers also collect health information from medical records and questionnaires.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
breath analysis for volatile organic compounds
What this could lead to
If breath analysis works, doctors could classify AML subtypes within hours instead of days, helping them choose the right treatment sooner.
What could go wrong
The trial is small and early, so breath signatures may not reliably distinguish AML subtypes or predict treatment response. Breath tests also depend on patients being able to use the mouthpiece, which some cannot.
