New immune cell therapy takes on virus after transplant
NCT ID NCT07368634
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tests a new treatment for Epstein-Barr virus (EBV) that can occur after a stem cell transplant. The treatment uses specially engineered immune cells (EBV-TCR-T cells) to find and destroy virus-infected cells. Up to 18 adult patients who have persistent EBV despite standard care will receive up to three infusions. The main goal is to check safety, but researchers will also see if the virus clears from the blood.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- EBV-TCR-T cells (engineered immune cells designed to target and kill Epstein-Barr virus-infected cells)
- What this could lead to
- If successful, this could offer a new treatment option for controlling Epstein-Barr virus after stem cell transplants, potentially preventing serious complications like lymphoproliferative disorders.
- What could go wrong
- This is a very early, small trial (18 participants) testing safety first. The treatment may not work, and there are risks like cytokine release syndrome or other infusion reactions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥ 18 years at the time of enrollment. * History of allogeneic hematopoietic stem cell transplantation. * Presence of Epstein-Barr virus (EBV) DNAemia confirmed by quantitative polymerase chain reaction (qPCR) in peripheral blood. * EBV DNAemia persisting or increasing despite standard management, as determined by the investigator. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Adequate organ function as defined by the study protocol. * Ability to understand and willingness to sign written informed consent. Exclusion Criteria: * Diagnosis of EBV-associated lymphoproliferative disorder requiring immediate cytotoxic chemotherapy. * Active, uncontrolled infection other than EBV. * History of severe autoimmune disease requiring systemic immunosuppressive therapy. * Uncontrolled graft-versus-host disease requiring high-dose systemic corticosteroids or other immunosuppressive treatment. * Prior treatment with EBV-specific adoptive T cell therapy within a defined washout period. * Known active malignancy other than EBV-related disease that may interfere with study participation. * Pregnant or breastfeeding women. * Any medical, psychological, or social condition that, in the opinion of the investigator, would interfere with safe participation in the study.
