Brief summary

The purpose of this study is to demonstrate that viral specific T-cells (a type of white blood cell) can be generated from an unrelated donor and given safely to patients with viral infections.

Detailed description

Viral reactivation and infection is a major cause of morbidity in immunocompromised patients (including HSCT recipients). In this study we will draw blood from unrelated (third party) donors and use the blood to generate viral specific T-cells (VSTs) with specificity for Epstein-Barr virus (EBV), cytomegalovirus (CMV), adenovirus (ADV), BK virus (BKV), and JC Virus. The VSTs will be infused into immunocompromised children with specific viral infections (EBV, CMV, ADV, BKV , or JC virus). Cells will be selected for infusion based on the recipient's HLA type and the viral specificity of the cells.

Interventions

VSTs will be infused into immunocompromised patients with evidence of viral infection or reactivation defined as any of the following: * Blood adenovirus PCR ≥ 1,000 * Blood CMV PCR ≥ 500 * Blood EBV PCR ≥ 9,000 * Plasma BKV PCR \>1,000 * Plasma JC Virus PCR \> 1,000 * Evidence of invasive adenovirus infection or disease, defined as the presence of adenoviral positivity by PCR or culture in one or more sites * Evidence of invasive CMV infection, eg pneumonitis, retinitis, colitis * Evidence of invasive EBV disease/infection, EBV-associated lymphoproliferation (EBV-LPD) defined as proven EBV-LPD by biopsy or probable EBV-LPD defined as an elevated EBV DNA level in the blood associated with clinical symptoms (adenopathy or fever or masses on imaging) but without biopsy confirmation, or EBV-associated malignancies * Evidence of symptomatic BK virus infection, which may include symptomatic hemorrhagic cystitis, or BK nephropathy * Evidence of PML or other CNS infection due to JC virus

Design outcomes

Primary

MeasureTime frameDescription
Successful production of viral specific T-cellsWithin 30 days post culture initiationOf the patients who had a VST culture initiated, successful production of VST cells is defined as meeting the protocol-defined release criteria.
Percentage of patients who do not have infusional toxicityThrough 30 minutes post infusionPatients will be monitored for infusional toxicity
Incidence of GVHD associated with VST infusionThrough 30 days after infusionPatients will be monitored for the development of VST associated GVHD

Secondary

MeasureTime frameDescription
Presence of viral-specific T-cellsAt 30 days after infusionPresence of viral-specific T-cells in the participant's blood will be assessed by Elispot assay
Viral burdenAt 30 days after infusionThe viral burden will be assessed using the protocol-defined efficacy assessment.
