This Phase I-II dose-finding trial to determine the optimal dose of intravenous (IV) injection dose of donor-derived cytotoxic T lymphocytes (CTLs) specific for CMV, EBV, BKV and Adenovirus. A maximum of 36 patients will be treated in up to 18 cohorts each of size 2, with the first cohort treated at the lowest dose level 1, all successive doses chosen by the EffTox method, and no untried dose level skipped when escalating.
The scientific goal of the trial is to determine an optimal IV-CTL cell dose level among the three doses 1.0x107cells/m2, 2 x107cells/m2 and 5x107cells/m2., hereafter dose levels 1, 2, 3. Dose-finding will be done using the sequentially adaptive EffTox trade-off-based design of Thall et al.

Experimental: CMV/AdV /EBV/BKV specific T cells
CMV/AdV /EBV/BKV specific T cells will be thawed and transferred to a syringe given by slow intravenous injection over 1-2 minutes. Three dose levels will be explored. The lowest dose level will be 1x107cells/m2 and the highest will be 5x107/m2.
Biological: CMV/AdV /EBV/BKV specific T cells
Each cohort of 2 patients will be treated and observed for 45 days for toxicity, dose escalation, and GvHD. The algorithm of sequentially adaptive EffTox trade-off-based design of Thall et al will be used to determine the dose for each cohort. If 1x107CTL/m2 results in unacceptable toxicity or efficacy, the study will be closed to accrual.
- Number of participants with investigational product-related adverse events as assessed by CTCAE v4.03 [ Time Frame: 45 days for toxicity ]The study will determine the optimal dose of intravenous injection of donor-derived cytotoxic T lymphocytes (CTLs) specific for CMV, EBV, Adenovirus and BK virus( BKV) given to patients with or at risk for CMV, EBV, BK virus and adenovirus infection after cord blood transplant. The safety will be assessed by investigational product-related adverse events as per CTCAE v4.03.
- Impact of CMV/AdV /EBV/BKV specific T cells will be measured by existence of cells in the system. [ Time Frame: 12 months ]To evaluate the impact of CTLs on CMV/AdV /EBV/BKV -specific T-lymphocyte immune reconstitution. The impact will be evaluated by the number of months/years of cell survival.
