This phase I/II trial studies the side effects of viral specific T cells and tests how well they work in treating adenovirus, cytomegalovirus (CMV), or Epstein-Barr virus (EBV) infection in patients who have undergone a stem cell or solid organ transplant or who have compromised immunity. Recent transplant or compromised immunity can lead to patients having very few, if any, T cells (a cell of the immune system to fight viruses) to be able to fight adenovirus, CMV, or EBV infection. Viral specific T cells are a form of antiviral adoptive immunotherapy, which encourages a virus-specific (either adenovirus, CMV, or EBV) T cell response in the patient after infusion. Viral specific T cells are created by collecting healthy T cells from a donor. The collected healthy T cells are stimulated and exposed to protein from the virus (either adenovirus, CMV, or EBV). The cells are then labeled with interferon gamma (a substance that can improve the body's natural response to infection and disease) and captured in a closed, sterile system. The captured cells are then infused into the patient to help with the virus-specific T cell response in the patient. Viral specific T cells may be safe, tolerable, and/or effective in treating adenovirus, CMV, or EBV infection in patients who have undergone a stem cell or solid organ transplant or who have compromised immunity.

PRIMARY OBJECTIVE:
I. To determine the safety and efficacy of administering partially matched allogeneic virus-specific T-lymphocytes (viral specific T cells) to mediate antiviral activity in hematopoietic cell transplantation (HCT) and solid organ transplantation (SOT) recipients and/or patients with compromised immunity with viral reactivation or infection.
SECONDARY OBJECTIVE:
I. To monitor the durability and kinetics of viral load following viral specific T cell infusion.
OUTLINE:
Donors undergo leukapheresis for T cell processing on study. Within 4 hours after cell processing, patients then receive viral specific T cells intravenously (IV). If at day 14 post-infusion or later, patients do not achieve a complete response, donors may undergo additional leukapheresis and patients may receive up to four additional viral specific T cell IV infusions, spaced at least 14 days apart, in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection throughout the study and, if clinically indicated, may undergo nasal swab or wash, bronchoalveolar lavage, urine, and/or other fluid or tissue sample collection throughout the study. Donors may optionally undergo blood sample collection throughout the study.
After completion of study treatment, patients are followed up at days 7, 14, 21, 28, 90, and 180.
