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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 whether giving anti-thymocyte globulin (ATG) at a dose tailored to each patient's body can improve outcomes after a half-matched stem cell transplant. ATG is used to prevent graft-versus-host disease, a serious complication where donor cells attack the patient's body. Researchers will compare the standard dosing approach with a personalized one based on a pharmacokinetic formula. The main goal is to see if the tailored approach improves survival without severe graft-versus-host disease or relapse within the first year.

What this could mean

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

Active substance
Anti-thymocyte globulin (ATG), a drug that suppresses the immune system to prevent graft-versus-host disease, given at a dose tailored to each patient using a pharmacokinetic formula.
What this could lead to
If this works, it could reduce severe complications like graft-versus-host disease and relapse after stem cell transplants, improving survival and quality of life for patients with blood cancers.
What could go wrong
This is a Phase 2 trial with 63 participants, so results are preliminary. The personalized dosing may not improve outcomes, and ATG can increase infection risk, including viral reactivation.
