About this trial
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).
Eligibility criteria
Qualifiers
Patients must have received allogeneic HSCT and be greater than 30 days post-HSCT at the time of registration.
Symptomatic with any detectable viral load OR
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
Disqualifiers
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.
