Brief Summary:

Cyclosporine (CNI), a potent immunosuppressive drug used in transplant recipients to prevent graft rejection, can cause renal impairment in some patients. The aims of this study are

  • To determine the influence of CNI discontinuation on the drug exposure and key pharmacokinetic parameters of everolimus and enteric-coated mycophenolate sodium (EC-MPS)
  • To determine the adequate dosing of everolimus and EC-MPS in a CNI-free regimen
  • To investigate the CNI-free regimen with EC-MPS and everolimus with respect to safety (e.g. rejection rates) and tolerability
  • To investigate renal function after CsA withdrawal

Condition or disease Intervention/treatment Phase
Renal Transplantation Drug: enteric-coated mycophenolate sodium Drug: everolimus Phase 4

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Pharmacokinetics of Everolimus and Enteric-Coated Mycophenolatesodium Before and After Withdrawal of Cyclosporine in Stable Renal Transplant Patients
Study Start Date : January 2004
Actual Study Completion Date : March 2006

Intervention Details:
    Drug: enteric-coated mycophenolate sodium
    Other Name: Myfortic
    Drug: everolimus
    Other Name: Certican

Primary Outcome Measures :
  1. Kinetic Profiles (MPA, everolimus, and optional IMPDH) will be measured at day 0, 7 and 7 days after complete removal of CsA and last dose adjustment of everolimus due to trough level outside target range [ Time Frame: 7 days ]
  2. Everolimus trough level will be measured at day 7, 14, 21, 28 and month 2, 4, 6, 9, 12 [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Safety and tolerability of the treatment regimen consisting over a one year period [ Time Frame: 1 year ]
  2. Renal function during the course of the trial, especially after CNI withdrawal. [ Time Frame: 1 year ]
  3. Routine laboratory parameters during the course of the trial. [ Time Frame: 1 year ]

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients having a kidney transplant since at least 6 months but for no longer than 5 years.
  • Patients in a stable condition in terms of graft function
  • Patients currently receiving EC-MPS and CsA with or without corticosteroids as part of their immunosuppressive regimen for at least 1 month prior to Baseline
  • Females of childbearing potential must have a negative serum pregnancy test prior to study inclusion. If positive, the patient will not be enrolled. Effective contraception must be used during the trial.

Exclusion Criteria:

  • Patients with any known hypersensitivity to EC-MPS or everolimus or other components of the formulation (e.g., lactose)
  • Patients with a history of severe rejection (according to BANFF criteria) within 3 months of enrollment in this trial.
  • Changes to the immunosuppressive regimen during the last 3 months due to immunologic reasons.
  • Patients with thrombocytopenia (platelets <100,000/mm3), with an absolute neutrophil count of <1,500/mm3 and/or leukocytopenia (leukocytes <4,500/mm3), and/or hemoglobin <9.0 g/dL at baseline.
  • Patients with proteinuria at baseline (> 1g/d)

Other protocol-defined inclusion/exclusion criteria may apply
