NCT ID NCT04635397

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed study looked at how immune cells recover in 61 adults who received a stem cell transplant for blood cancers. Researchers measured the function of T and NK cells by testing their cytokine profiles after stimulation. The goal was to see if these measurements could help predict and manage complications like infections, relapse, and graft-versus-host disease (GvHD).

What this could mean

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

What this could lead to
If successful, this could help doctors personalize post-transplant care by adjusting immune-suppressing drugs or anti-infection treatments based on a patient's immune recovery.
What could go wrong
This is an observational study, not a treatment trial. It aims to gather information, not test a new therapy, so it won't directly improve outcomes for participants.
