Primary Outcome Measures:
  • Incidence of biopsy-proven acute allograft rejection during the first post-transplant year [ Time Frame: acute rejection proved by graft biopsy ]

Secondary Outcome Measures:
  • Proportion of patients who experienced an acute rejection episode, whether confirmed by biopsy or not at 1 year. [ Time Frame: graft dysfunction ]
  • Proportion of patients who experienced more than one episode of acute allograft rejection [ Time Frame: graft dysfunction, biopsies ]
  • Proportion of patients who experienced an acute rejection episode that required therapy by anti-lymphocyte antibodies (ATG or OKT3) [ Time Frame: 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 [ Time Frame: graft dysfunction and biopsies ]
  • Banff grade of the first rejection episode [ Time Frame: graft biopsy ]
  • Incidence of adverse events in the two treatment arms at 1 year [ Time Frame: number of adverse events reported by the investigators ]
  • Incidence of delayed graft function [ Time Frame: number of patient who required hemodialysis during the first week post transplantation ]
  • Graft function at 1 year [ Time Frame: serum creatinine and estimated glomerular filtration rate ]
  • Graft and patient survival at 1 year [ Time Frame: number of graft failures and/or deaths ]

Primary Completion Date: November 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1, ATG
Thymoglobulin induction during 8 days (1.25 mg/kg per day) associated with tacrolimus, mycophenolate mofetil and steroids
Drug: Thymoglobulin (ATG)
Thymoglobulin: 1.25 mg/kg per day from day 0 to day 7 post transplantation
Other Name: Thymoglobulin, Genzyme
Active Comparator: 2, Daclizumab
Dacluzamb induction (five infusions, 1 mg/kg per infusion) associated with tacrolimus, mycophenolate mofetil and steroids
Drug: Daclizumab
Daclizumab: 1mg/kg at day 0, 14, 28, 42 and 56 post transplantation
Other Name: Zenapax, Roche

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.
