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

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 Results may not be published yet.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

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.

Summary

This study tested a personalized treatment for a young adult with a severe EBV-related lymphoma that occurred after a stem cell transplant. The patient received up to four infusions of specially grown immune cells from their original stem cell donor. The goal was to see if these cells could safely control the lymphoma and improve the body's ability to fight the virus.

What this could mean

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

Active substance
EBV-specific T cells (donor-derived immune cells)
What this could lead to
If successful, this approach could offer a way to control EBV-related lymphoma after a stem cell transplant without causing severe graft-versus-host disease.
What could go wrong
This was a single-patient study, so results may not apply to others. The treatment carries risks like graft-versus-host disease or infection.
