Brief Summary:

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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 36 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Adoptive Cord Blood ImmunotHerapy Using Expanded Cord Blood T Cells for EBV, CMV, BKV and Adenovirus Reactivation/Infection or ProphylaxiS
Actual Study Start Date : January 24, 2018
Estimated Primary Completion Date : July 2021
Estimated Study Completion Date : November 2022

Arm Intervention/treatment
Experimental: CMV/AdV /EBV/BKV specific T cells
CMV/AdV /EBV/BKV specific T cells will be thawed or thawed and diluted into a total volume of 10 mL of Plasmalyte A and 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
At each dose level, two to six patients will be treated and observed for 45 days for toxicity, dose escalation and for GvHD. If one of the initial cohort of two patients experience Dose Limiting Toxicity (DLT), then four additional patients will be treated at this dose level. If two or more of the six patients experience DLT, then this dose level will be considered unacceptable toxicity and the number of infused CTL will be de-escalated unless we are at the initial dosing levels. If 1x107CTL/m2 results in unacceptable toxicity, the study will be closed to accrual.

Primary Outcome Measures :
  1. 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 safety, toxicity and maximum tolerated dose (MTD) after administering 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.

Secondary Outcome Measures :
  1. 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.

Layout table for eligibility information
Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Inclusion Criteria at the Time of Procurement

  • Pediatric and adult patients (there are no lower and upper age limits for patients) with malignant or nonmalignant diseases who are candidates for transplant.
  • Patients must have a CB unit (or units) matched with the patient at 4, 5, or 6/6 HLA class I (serological) and II (molecular) antigens. The unit selected for CTL expansion must be either:

    1. be cryopreserved in two fractions, with a minimum of 2.5x107 total nucleated cells (TNC) per kg pre-thaw in the fraction which will be used for the primary transplant. The remaining fraction will be used to generate the CTLs to give at day 30 or beyond as described below. OR
    2. be cryopreserved with a cell dose that totals > 3x10e7 TNC per kg pre thaw. On thaw, 20% of the total volume will be used for CTL manufacture to give at day 30 or beyond and the remaining 80% will be used for the primary transplant.
    3. For recipients of double CBT, if possible both CB units should be cryopreserved in two fractions and T-cells will be made from both units if possible.

Inclusion Criteria at the Time of CTL Infusion

  • Recipients of at least one unmanipulated cord blood unit as described above (i.e. from a HLA matched or mismatched unrelated donor) transplant at risk for or with CMV/Adenoviral/BKV and/or EBV infection or reactivation.
  • Lansky/Karnofsky scores ≥60
  • Absolute neutrophil count (ANC) greater than 500/u
  • No evidence of GVHD > Grade II at time of enrollment
  • Life expectancy > 30 days
  • Absence of severe renal disease (Creatinine < 3x normal for age)
  • Absence of severe hepatic disease. Direct bilirubin must be < 3 mg/dl and AST < 5x upper limit of normal
  • Patient must be at least 30 days post transplant to be eligible to receive CTL
  • Written informed consent and/or signed assent line from patient, parent or guardian
  • Patient not on Fi02 of >60%

Exclusion Criteria:

Exclusion Criteria at the Time of Procurement

  • Pregnant or lactating
  • Patients with active central nervous system disease
  • Patients with Karnofsky performance status <70%
  • Patients with grade 3 or 4 or primary myelofibrosis
  • Patients with suitable related donors Exclusion Criteria at the Time of CTL Infusion
  • Pregnant or lactating
  • Unable to wean steroids to ≤0.5 mg/kg/day prednisone or equivalent
  • Patients with Grade 3 hyperbilirubinemia
  • Patients with other uncontrolled infections (except CMV and/or adenovirus and/or EBVemia and/or BK viruria/viremia). For bacterial infections, patients must be receiving definitive therapy and have no signs of progressing infection for 72 hours prior to enrollment. For fungal infections patients must be receiving definitive systemic anti-fungal therapy and have no signs of progressing infection for 1 week prior to enrollment. Progressing infection is defined as hemodynamic instability attributable to sepsis or new symptoms, worsening physical signs or radiographic findings attributable to infection. Persisting fever without other signs or symptoms will not be interpreted as progressing infection.
  • Patients with less than 50% donor chimerism in either peripheral blood or bone marrow or patients with relapse of original disease
  • Patients who have received investigational (IND) product within 28 days of screening for CTL infusion under this study
