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 This study
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 Results may not be published yet.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

Summary

This trial investigates whether giving two low doses of rituximab shortly after a stem cell transplant can prevent serious Epstein-Barr virus (EBV) infections. Participants are adults aged 16-65 who have received a donor stem cell transplant and are at medium-to-high risk for EBV reactivation. Half receive standard care plus rituximab infusions on days 21 and 28 after transplant, while the other half receive standard care alone. The study tracks EBV levels, complications, and survival for up to one year.

What this could mean

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

Active substance
a low-dose infusion of rituximab, a drug that targets certain immune cells, given preventively after transplant
What this could lead to
If successful, this approach could reduce the risk of serious EBV-related complications after stem cell transplants, potentially improving survival and quality of life.
What could go wrong
This is a single-center trial with a moderate number of participants, so results may not apply broadly. Rituximab can cause infusion reactions and increase infection risk.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: \- Aged between 16 and 65 years old. Recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Clinically stable condition allowing administration of study intervention at post-transplant Day +21. EBV-DNA quantitative test completed within 48 hours prior to randomization. Written informed consent signed by the participant or legal authorized representative. Exclusion Criteria: \- Presence of clinically significant EBV infection or meeting criteria for EBV preemptive therapy before randomization. Prior rituximab administration during conditioning regimen. Confirmed or highly suspected post-transplant lymphoproliferative disorder (PTLD). Severe anaphylactic history to rituximab or any excipients of the preparation. Active uncontrolled severe systemic infection.
