The aim of this trial is to collect evidence of the safety of administering autologous CD4+CD25+FoxP3+ natural regulatory T cells (nTregs) to living-donor renal transplant recipients. In addition, the study will determine whether post-transplant nTregs infusion allows a tapering of conventional maintenance immunosuppression within 60 weeks after transplantation.
The ONE Study aims to explore the feasibility, safety and efficacy of regulatory cell therapies as adjunct immunosuppressive treatments in the context of living-donor renal transplantation.The clinical trial presented here (ONEnTreg13) will test autologous, polyclonally expanded CD4+CD25+FoxP3+ nTregs as a somatic cell-based medicinal product.
The objective of this study is to determine whether administration of nTregs to recipients of living-donor kidney transplants is safe and able to polarize the immunological response of the recipient away from graft rejection and towards graft acceptance, allowing a reduction in the doses of pharmacological maintenance immunosuppression.

|---|---|---|---|---|
| autologous CD4+CD25+FoxP3+ natural regulat. T cells (nTregs) | Biological | autologous CD4+CD25+FoxP3+ natural regulatory T cells (nTregs). nTregs will be infused at escalating doses of 0.5 x 10^6, 1 x 10^6, and 2.5-3 x 10^6 cells/kg body weight in cohorts of three patients each. |
| Measure | Description | Time Frame |

| Incidence of infectious complications associated with cell administration. | 60 weeks | |
| Incidence of embolic pulmonary complications and other embolic events. | 60 weeks | |
| Incidence of immune responses resulting in anaphylactic reactions, cardiovascular compromise or other acute organ failure. | 60 weeks | |
| Biochemical disturbances associated with the cell infusion. | 60 weeks | |
| Over-suppression of the immune system assessed by the incidence of opportunistic infections, especially, CMV, EBV and polyoma virus. | 60 weeks | |
| Over-suppression of the immune system assessed by the incidence of neoplasia. | 60 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Prevention of acute rejection will be secondarily assessed by measuring | i) time to first acute rejection episode ii) severity of acute rejection episodes based on response to treatment and histological scoring iii) the level of total immunosuppression drugs at the final trial visit. | 60 weeks |
| Incidence of patients treated for subclinical acute rejection on the basis of histopathological findings |

| Prevention of chronic graft dysfunction (chronic rejection or IF/TA) will be assessed by clinical (impairment of GFR) and histopathological (Banff staging) measures. | 60 weeks |
| Incidence of post-transplant dialysis, inclusion on the transplant waiting list or retransplantation following graft loss through rejection (acute or chronic). | 60 weeks |
| Avoidance of drug-related complications by immunosuppressant reduction will be assessed by the incidence of reported adverse drug reactions. | 60 weeks |
