Maintenance Neoral Monotherapy Compared to Bitherapy in Renal Transplantation

We have previously defined factors that predict the long term success of maintenance CsA monotherapy (CsAm) after kidney transplantation : donor age < 40 years, serum creatinine level at the initiation of CsAm £ 125 µmol/L, no rejection episode before CsAm initiation. We have also shown that the 8-year graft survival in 329 selected patients enrolled in maintenance CsA-m was 84 % (Hurault de Ligny et al, Transplantation, 2000 ; 69 : 1327-1332). These results were obtained with an old formulation of cyclosporin, azathioprine, steroid withdrawal over the first year and induction antibody. This prospective randomized multicentre study was designed to clarify whether maintenance Neoral + MMF or Neoral + AZA is better than a CsAm and wether Neoral + MMF is better than Neoral + AZA in low immunological risk cadaveric kidney transplant recipients.

About this study

Between july 1998 and january 2004 selected patients were randomly assigned equally within each centre to receive CsAm or bitherapy with equally CsA + MMF or CsA + AZA.

Cyclosporin A: C0: 75-125ng/ml-dose adapted in the 3 groups

Drug

Group A: CsA + Azathioprine(1 to 2 mg/kg/day)

Drug

Group B: CsA + CellCept(500 mg x 2/day)

Drug

Group C: CsAm

Drug

Primary outcomes

  1. to compare maintenance CsAm with dual therapy groups and within dual therapy MMF with AZA for :

  2. The incidence and the delay of occurrence of graft dysfunction episode defined as ³ 20 % increase in serum creatinine level (mean of three results obtained in the same laboratory) and requiring a graft biopsy.

  3. Causes of graft dysfunction episodes diagnosed by graft biopsy.

  4. The incidence of serious infections (HVZ, EBV, HPV genital infection, febrile UTI, pneumonitis...)

Secondary outcomes

  1. To compare the three treatment groups for the following parameters :

  2. Incidence of therapeutic failure defined by biopsy proven acute rejection episode or CsA renal toxicity

  3. Graft function evaluated by serum creatinine level and calculated creatinine clearance (CG formula)

  4. Adverse events

  5. Patient and graft survival
