Antigen Specific Adoptive T Cell Therapy for Adenovirus Infection After Hematopoietic Stem Cell Transplantation
What this study is about
The purpose of this study is to determine if it is possible to treat an infection with a cell-based immunotherapy (therapy that uses the patient's own immune system to treat the infection). This treatment is called adoptive T cell therapy. Another purpose is to learn about the side effects and toxicities of adoptive T cell therapy.
View original scientific description
The purpose of this study is to determine if it is possible to treat an infection with a cell-based immunotherapy (therapy that uses the patient's own immune system to treat the infection). This treatment is called adoptive T cell therapy. Another purpose is to learn about the side effects and toxicities of adoptive T cell therapy. Adoptive T cell therapy is an investigational (experimental) therapy that works by using the blood of a donor that has immunity against the virus. The donor cells are collected and then the cells, called T cells, that are capable of defending against the virus are selected out. These selected T cells are then infused back into the patient, to try to give the immune system the ability to fight the infection. Adoptive T cell therapy is experimental because it is not approved by the Food and Drug Administration (FDA).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients must have received allogeneic HSCT and be greater than 30 days post-HSCT at the time of registration.
- Patients must have evidence of documented HAdV infection/reactivation. Patients may be:
- Symptomatic with any detectable viral load OR
- Asymptomatic with viral load that is: \>1000 copies/ml in peripheral blood OR qualitative detection in stool, urine and/or other specimens
- Patients must have poor response and/or contraindication to therapy:
- Absence of an improvement of viral load (decrease by at least 1 log, i.e. 10-fold) after ≥ 14 days of antiviral therapy with ganciclovir, valganciclovir and/or foscarnet. OR
- New, persistent and/or worsening HAdV-related symptoms, signs and/or markers of end organ compromise while on antiviral therapy with ganciclovir, valganciclovir or foscarnet. OR
- Have contraindications or experience adverse effects of antiviral therapy with ganciclovir, valganciclovir, cidofovir or foscarnet.
- Performance Score: Eastern Cooperative Oncology Group (ECOG) Performance Score ≤ 3. Karnofsky (≥ 16 years) or Lansky (\<16 years) performance score ≥ 50
- The effects of virus-specific, antigen-selected T cells on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (double barrier method of birth control or abstinence) 4 weeks prior to study entry, for the duration of study participation and for 3 months after completing treatment.
- Subjects who are 14 years and older must have the ability to understand and the willingness to sign a written informed consent document, or assent document.
Exclusion criteria
- Pregnant or breastfeeding women are excluded from this study. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with the agents described above, breastfeeding should be discontinued if the mother participates in this trial.
- Patients with opportunistic viral infections other than HAdV.
- Patients with active, grade II-IV, acute graft versus host disease (GVHD), chronic GVHD or any condition requiring high doses of glucocorticosteroid (\>0.5 mg/kg/day prednisone or its equivalent) as treatment.
- Treatment with antithymocyte globulin within 28 days of planned infusion of virus - specific, antigen selected T cells.
- Treatment with virus - specific T cells within 6 weeks (42 days) of planned infusion.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
