About this trial
The purpose of this study is to determine if a specific type of cell-based immunotherapy, using T-cells from a donor that are specific against cytomegalovirus (CMV) is feasible to treat infections by CMV.
Adoptive T-cell therapy is an investigational (experimental) therapy that works by using the blood of a donor and selecting the T-cells that can respond against a specific infectious entity. These selected T-cells are then infused to 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 hematopoietic stem cell transplant and be greater than 30 days post-transplant at the time of registration
Patients must have documented opportunistic CMV infection, or reactivation; the criteria include (both of the following criteria must be met)
Patients may have asymptomatic viremia (>1000 copies/ml) OR presence of symptoms secondary to CMV infection, AND
Absence of an improvement of viral load after ≥ 14 days of antiviral therapy with ganciclovir, valganciclovir or foscarnet (decrease by at least 1 log, i.e. 10-fold) or
Disqualifiers
Pregnant or breastfeeding women are excluded from this study.
Patients with opportunistic viral infections other than CMV.
Patients with active, grade 2-4, acute graft vs. 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.
