Brief summary
To compare renal allograft rejection rates during the first year among high-immunological risk recipients between patients who received either ATG or the anti-IL2R mAb daclizumab.
Detailed description
The objective of this randomized, multi-center trial is to directly compare the ATG, Thymoglobulin, with the anti-CD25 mAb, daclizumab, in a high-risk, HLA-sensitized renal transplant population, in order to elucidate whether there is any significant difference in the incidence of acute rejection after one year. Eligible patients were randomized (1:1) to receive either ATG (1.25 mg/kg/d from day 0 to day 7) or daclizumab (1 mg/kg at days 0, 14, 28, 42 and 56). Maintenance immunosuppression comprised tacrolimus, MMF and prednisone. The study's primary endpoint was the incidence of biopsy-proven acute rejection at one year.
Interventions
Thymoglobulin: 1.25 mg/kg per day from day 0 to day 7 post transplantation
Daclizumab: 1mg/kg at day 0, 14, 28, 42 and 56 post transplantation

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence of biopsy-proven acute allograft rejection during the first post-transplant year | acute rejection proved by graft biopsy |
Secondary
| Measure | Time frame |
|---|---|
| Proportion of patients who experienced more than one episode of acute allograft rejection | graft dysfunction, biopsies |
| Proportion of patients who experienced an acute rejection episode that required therapy by anti-lymphocyte antibodies (ATG or OKT3) | number of anti-lymphocyte treatment required for acute rejection episodes |
| Number of acute rejection episodes per therapeutic arms and mean number of acute rejection episode per patient in each arm | graft dysfunction and biopsies |
| Banff grade of the first rejection episode | graft biopsy |
| Proportion of patients who experienced an acute rejection episode, whether confirmed by biopsy or not at 1 year. | graft dysfunction |
| Incidence of delayed graft function | number of patient who required hemodialysis during the first week post transplantation |
| Graft function at 1 year | serum creatinine and estimated glomerular filtration rate |
| Graft and patient survival at 1 year | number of graft failures and/or deaths |
| Incidence of adverse events in the two treatment arms at 1 year | number of adverse events reported by the investigators |
