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 or 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 DNA viruses. 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 or CMV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.
If a subject shows a partial response, defined as a decrease in viral load of at least 50% from baseline or 50% improvement of clinical signs and symptoms, or no response, they are eligible to receive up to 4 additional cellular infusions from the same donor, at a minimum of 14-day intervals. If the same donor is no longer available, eligible, or appropriate, another donor may be considered for a maximum of 4 total cellular infusions at the discretion of the study PI and treating physician. A subject will not exceed a maximum of 5 total infusions from 2 donors.
Subjects are followed for 1 year post initial viral-specific T cell infusion. If subjects receive additional infusion(s), GvHD and adverse events will be followed for an additional 90 days from last infusion. Data may be abstracted from subjects' medical charts for an additional 1 year after most recent viral-specific T cell infusion.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Viral Specific T-Lymphocytes | Experimental | Peripheral blood mononuclear cells will be collected from the donor and loaded onto our Miltenyi Biotec CliniMACS Prodigy® or CliniMACS® Plus where they will be stimulated in vitro with viral-specific antigen(s). The cells are then immunomagnetically labeled with interferon gamma via the cytokine capture system. By this method, viral specific, gamma-secreting T cells, are captured in a closed, sterile system. |

Participants were enrolled at UPMC (University of Pittsburgh Medical Center).
Participants were able to receive up to 5 infusions. If a subject showed a partial response, defined as a decrease in viral load of at least 50% from baseline or 50% improvement of clinical signs and symptoms, or no response, they were eligible to receive up to 4 additional cellular infusions from the same donor, at a minimum of 14-day intervals.
