  Purpose

This study introduces a new optimization immunosuppressive regimen associating tacrolimus at a reduced dose and enteric-coated mycophenolate sodium at an increased dose in order to slow down renal function worsening and to prevent the progression of chronic allograft nephropathy, while maintaining the same efficacy, in maintenance renal transplant recipients.

Primary Outcome Measures:
  • Renal Function Assessed by Change in Estimated Glomerular Filtration Rate(eGFR) [ Time Frame: Baseline and Month 6 ] [ Designated as safety issue: No ]
    Change in estimated glomerular filtration rate from baseline to Month 6 calculated by using abbreviated Modification of Diet in Renal Disease (MDRD) formula. Modification of Diet in Renal Disease (MDRD) formula is: GFR [mL/min/1.73m^2] = 186.3*(C^-1.154)*(A^-0.203)*G*R where -C is the serum concentration of creatinine [mg/dL], -A is patient age at sample collection date [years], -G=0.742 when gender is female, otherwise G=1, -R=1.21 when race is black, otherwise R=1.


Secondary Outcome Measures:
  • Renal Function at 3 Months Assessed by Change in Estimated Glomerular Filtration Rate (eGFR) [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
    Change in estimated glomerular filtration rate from baseline to Month 3 calculated by using abbreviated MDRD formula. Modification of Diet in Renal Disease (MDRD) formula is: GFR [mL/min/1.73m^2] = 186.3*(C^-1.154)*(A^-0.203)*G*R where -C is the serum concentration of creatinine [mg/dL], -A is patient age at sample collection date [years], -G=0.742 when gender is female, otherwise G=1, -R=1.21 when race is black, otherwise R=1.

  • Number of Participants With Treatment Failure Parameters (Biopsy-Proven Acute Rejection (BPAR), Graft Loss, Death, or Loss to Follow-up) at 6 Months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    A biopsy-proven acute rejection (BPAR) is defined as a biopsy graded IA, IB, IIA, IIB, or III based on the Banff 1997 classification.The allograft was presumed lost on the day the patient started dialysis and was not able to subsequently be removed from dialysis. If the patient went through a graft nephrectomy, then the day of nephrectomy was the day of graft loss.

  • Number of Participants With Graft and Patient Survivals at 6 Months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Graft survival was defined as the number of patients with no graft loss. The allograft was presumed lost on the day the patient started dialysis and was not able to subsequently be removed from dialysis. If the patient went through a graft nephrectomy, then the day of nephrectomy was the day of graft loss. Patient survival was defined as the number of patients alive with or without a functioning graft.

Arms Assigned Interventions
Active Comparator: Standard dose EC-MPS
Patients received 720 mg/day (360 mg twice a day (bid) orally) Enteric-coated mycophenolate sodium (EC-MPS) and tacrolimus dose (twice a day orally) adjusted to maintain the trough blood level (C0) contained between 5.5 and 10 ng/mL. The randomization was stratified on 1 factor: treatment with or without steroids. Prednisone (or oral equivalent) was administrated to patients as before entering the study and as per center's standard practice, but at a dose of at least 5 mg/day.
Drug: Enteric-coated mycophenolate sodium (EC-MPS)
Other Name: Myfortic
Drug: Tacrolimus
Other Name: Prograf
Drug: Corticosteroids
At a dose of at least 5 mg/day.
Other Name: Prednisone
Experimental: High EC-MPS
Patients received 1440 mg/day (720 mg twice a day (bid) orally) Enteric-coated mycophenolate sodium (EC-MPS) and tacrolimus dose (twice a day orally) tapered to reach a trough blood level target contained between 2 and 4.5 ng/mL within 15 days after randomization at the most. The randomization was stratified on 1 factor: treatment with or without steroids. Prednisone (or oral equivalent) was administrated to patients as before entering the study and as per center's standard practice, but at a dose of at least 5 mg/day.
