Enteric-coated Mycophenolate Sodium (EC-MPS) With Reduced-dose Tacrolimus Versus EC-MPS With Standard-dose Tacrolimus in Stable Kidney Transplant Recipients (OLYMPE)

March 31, 2011 updated by: Novartis

A Multicenter, National, Open-label, Prospective, Randomized Study to Evaluate Efficacy and Tolerability of Enteric-coated Mycophenolate Sodium 1440 mg/Day With Tacrolimus Reduced Dose Versus Enteric-coated Mycophenolate Sodium 720 mg/Day With Tacrolimus Standard Dose, in Maintenance, Stable, Adult, Kidney Transplant Recipients

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.

Description

Inclusion Criteria:

  • Primary or secondary kidney transplant
  • Treatment with mycophenolic acid (MMF 1 g/d or EC-MPS 720 mg/d) and tacrolimus (trough concentration [C0] ≥ 5.5 ng/mL)
  • Creatinine clearance ≥ 30 mL/min and < 60 mL/min and stable renal function

Exclusion Criteria:

  • Multi-organ recipients or previous transplant with any other organ different from kidney
  • Biopsy proven acute rejection or treated acute rejection within the last 3 months.
  • Prescription of mycophenolate mofetil 1 g/d or mycophenolate sodium 720 mg/d due to adverse event occurrence when higher doses were administered

Other protocol-defined inclusion/exclusion criteria may apply.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.
Other Names:
  • Prograf
Other Names:
  • Myfortic
At a dose of at least 5 mg/day.
Other Names:
  • 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.
Other Names:
  • Prograf
Other Names:
  • Myfortic
At a dose of at least 5 mg/day.
Other Names:
  • Prednisone

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Renal Function Assessed by Change in Estimated Glomerular Filtration Rate(eGFR)
Time Frame: Baseline and Month 6
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.
Baseline and Month 6

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Renal Function at 3 Months Assessed by Change in Estimated Glomerular Filtration Rate (eGFR)
Time Frame: Baseline and 3 months
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.
Baseline and 3 months
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
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.
6 months
Number of Participants With Graft and Patient Survivals at 6 Months
Time Frame: 6 months
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.
