Donor immune cells aim to fight virus in vulnerable patients
NCT ID NCT03425526
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This early-stage trial tests whether specially grown donor T cells can safely treat adenovirus infections in people with weakened immune systems, such as cancer patients. The cells are designed to target and kill the virus. The study will check for side effects and see if the infection improves.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- donor T cells (adenovirus-specific cytotoxic T lymphocytes)
- What this could lead to
- If it works, this could offer a treatment option for dangerous adenovirus infections in people with weakened immune systems.
- What could go wrong
- This is a very early phase 1 trial with only 16 participants, so it may not work or could cause side effects. The cells are from donors, which carries risks like rejection.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Immunocompromised patients. * English and non-English speaking patients. * Written informed consent and/or signed assent from patient, parent or guardian. * Negative pregnancy test in female patients of childbearing potential, defined as not post-menopausal for 12 months or no previous surgical sterilization. Women of child bearing potential must be willing to use an effective contraceptive measure while on study. * Patients age 1 year or older with asymptomatic adenovirus viremia defined as no symptoms of adenovirus disease and EITHER two positive and quantifiable qPCR tests taken one week apart or one single measurement with \>/= 1000 copies. * Patients age 1 year or older with criteria of probable or definitive adenoviral diseases as defined in Appendix A. * Willingness to comply with the study protocol requirements. Exclusion Criteria: * Patients receiving prednisone \> 0.1 mg/kg/day or equivalent at time of enrollment, or who have received anti-thymocyte globulin (ATG) within 14 days or have received donor lymphocyte infusion (DLI) or Campath within 28 days of enrollment. * Patients with other uncontrolled infections: For bacterial infections, patients must be receiving therapy and have no signs of progressing infection for 72 hours prior to enrollment. For fungal infections patients must be receiving anti-fungal therapy and have no signs of progressing infection for 1 week prior to enrollment. Progressing infection is defined as hemodynamic instability attributable to sepsis or new symptoms, worsening physical signs or radiographic findings attributable to infection. Persisting fever without other signs or symptoms will not be interpreted as progressing infection. * Active acute graft versus host disease (GVHD) grade \>= 2.
