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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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

This trial tests a treatment strategy for adults with acute myeloid leukemia (AML) that did not respond to standard induction chemotherapy. Participants receive clofarabine and intermediate-dose Ara-C chemotherapy, followed by a reduced-intensity allogeneic stem cell transplant using donor cells. The goal is to see whether this sequential approach improves survival at two years after transplant. The trial enrolls adults aged 18 to 55 who have a suitable matched donor.

What this could mean

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

Active substance
clofarabine combined with intermediate-dose cytarabine (Ara-C) chemotherapy, followed by a reduced-intensity allogeneic stem cell transplant
What this could lead to
If it works, this approach could offer a path to long-term remission for adults whose AML did not respond to standard induction chemotherapy, a group with few good options.
What could go wrong
The trial is small and early-stage, so results may not hold up in larger studies. The treatment combines intensive chemotherapy with a donor stem cell transplant, which carries serious risks including infections, graft-versus-host disease, and organ damage.
