Summary

The study will test the hypothesis that CMV TCR-transduced T cells, at a specific T-cell dose/kg, can generate a functional CMV immune response post-transplant, where CMV-specific donor T cells cannot be isolated by conventional means. This will be tested in the context of adult HLA-matched sibling allogeneic HSCT.

In the proposed trial, an HLA-A\*0201-restricted CMV pp65-specific T cell receptor (TCR) will be introduced into donor T cells via ex vivo GMP retroviral transduction. Donor T cells will be isolated from peripheral blood following a simple venesection procedure. The CMV TCR-transduced T cells will be tested for TCR expression, CMV-specific cytokine secretion and microbiological contamination before being frozen and stored at -80C. CMV seropositive transplant recipients will be tested weekly for CMV reactivation by quantitative PCR on peripheral blood. On first detection of CMV DNA \> 200 copies/ml, 104 (cohort 1) or 105 (cohort 2) bulk CMV TCR-transduced T cells/kg recipient weight will be infused into the patient.

Blood will be taken regularly to determine persistence and expansion of the CMV TCR-transduced T cells. Weekly CMV PCR will be continued. Patients will be examined at appropriate intervals (daily if inpatients, twice weekly in BMT clinic if outpatients) for the development of graft versus host disease (GVHD) or other potential side effects.
