Could a simple drug infusion stop a dangerous virus after stem cell transplants?
NCT ID NCT07703657
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
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. Active hepatitis B virus (HBV) infection without standardized antiviral prophylaxis or treatment. Pregnant or breastfeeding female subjects. Subjects judged ineligible for participation by the investigator for any other reason.
