What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2 trial tests a stem cell transplant using a milder chemo and radiation regimen for people with blood cancers like AML and MDS. The goal is to see if this approach improves survival at 100 days after transplant. Participants receive donor stem cells along with drugs to prevent graft-versus-host disease. The study is currently recruiting 132 patients aged 2 to 75.

What this could mean

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

Active substance
Treosulfan, Fludarabine, total body irradiation, tacrolimus, and cyclophosphamide
What this could lead to
If successful, this could offer a safer stem cell transplant option for people with blood cancers, reducing side effects and improving survival.
What could go wrong
This is a mid-stage trial with only 132 participants, so results may not apply to everyone. There are risks of infection, graft-versus-host disease, and organ damage.
