Viral Specific T-Lymphocytes to Treat Infection With Adenovirus, Cytomegalovirus or Epstein-Barr Virus in Patients With Compromised Immunity
United States25 participantsStarted 2025-04-30
Plain-language summary
The primary purpose of this phase I/II study is to evaluate whether partially matched, ≥2/6 HLA-matched, viral specific T cells have efficacy against adenovirus, CMV, and EBV, in subjects who have previously received any type of allogeneic HCT or solid organ transplant (SOT), or have compromised immunity. Reconstitution of anti-viral immunity by donor-derived cytotoxic T lymphocytes has shown promise in preventing and treating infections with adenovirus, CMV, and EBV. However, the weeks taken to prepare patient-specific products, and cost associated with products that may not be used limits their value. In this trial, we will evaluate viral specific T cells generated by gamma capture technology. Eligible patients will include HCT and/or SOT recipients, and/or patients with compromised immunity who have adenovirus, CMV, or EBV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.

Inclusion criteria
. Patient, parent, or legal guardian must have given written informed consent, according to FDA guidelines. For patients ≥ 7 years of age who are developmentally able, assent or affirmation will be obtained, if feasible.
. Male or female, 1 month through 65 years old, inclusive, at the time of informed consent.
. Prior allogeneic hematopoietic stem cell transplant, AND/OR prior solid organ transplant (liver, kidney, lung and/or heart, intestinal, pancreatic, and/or multivisceral), AND/OR diagnosis of primary immunodeficiency AND/OR current/recent administration of immunosuppressive therapy for cancer or autoimmune disease.
. If receiving steroids, must be able to taper dose to less than 1 mg/kg/day prednisone (or equivalent) prior to cellular infusion.
. Negative pregnancy test for females ≥10 years old or who have reached menarche, unless surgically sterilized or post-menopausal.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Grade III-IV Acute Graft versus host disease
Timeframe: Day 0 through 90 days after last cellular infusion
2
CTCAE Grade 4/5 Adverse Events
Timeframe: Day 0 through 30 days from last cellular infusion
. Diagnosis of Adenovirus, CMV, or EBV infection, persistent despite standard therapy.
. Active adenovirus infection: (i.e. gastroenteritis, pneumonia, hemorrhagic cystitis, hepatitis, pancreatitis, meningitis) defined as the demonstration of adenovirus by biopsy specimen from affected site(s) (by culture or histology), or the detection of adenovirus by culture, PCR or direct fluorescent antibody stain in fluid in the presence of worsening or persistent clinical or imaging findings despite at least 14 days of appropriate antiviral therapy (i.e. cidofovir, brincidofovir, or other available pharmacological agents)
. Refractory adenoviremia: defined as DNAemia ≥1000 copies/mL or \<1 log decrease after at least 2 weeks of appropriate antiviral therapy (i.e. cidofovir, brincidofovir, or other available pharmacological agents)
Exclusion criteria
. Received ATG or Alemtuzumab within 21 days of viral-specific T cell infusion and a lack of evidence of T cell survival, defined by \<10 CD3+ T cells/uL (in unique situations, plasmapheresis may be considered).
. Active acute GVHD grades II-IV.
. Active severe chronic GVHD.
. Received donor lymphocyte infusion, with the exception of a fraction of an umbilical cord blood, within 21 days of planned viral-specific T cell infusion. Subjects receiving a fraction of an umbilical cord blood within 21 days of the viral-specific T cell infusion will not be excluded.
. Active and uncontrolled relapse of malignancy (other than EBV+ post-transplant lymphoproliferative disorder or lymphoma).
. Anticipated initiation of new lymphotoxic therapy within 4 weeks of viral-specific T cell infusion.
. Patients who are pregnant or lactating.
. Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, or concomitant medications, which, in the opinion of the investigator, may pose additional risks to participation in the study, may interfere with the participant's ability to comply with study requirements, or that may impact the quality or interpretation of the data obtained from the study.
