Brief Summary:
Renal transplant recipients need life long immunosuppression and one of the new drugs is everolimus. Everolimus is a potent immunosuppressive drug and one of the main side-effects are increased blood cholesterol levels. Many renal transplant recipients are treated with a cholesterol lowering agent, mainly fluvastatin. Rosuvastatin is a new cholesterol lowering drug on the market with a potential higher cholesterol lowering potency. In the present study the investigators will examine the hypothesis that rosuvastatin reduce cholesterol levels more than fluvastatin in renal transplant patients.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The RITA-study -- An Open Study to Evaluate the Blood Lipid Lowering Effect of Rosuvastatin Versus Fluvastatin and the Bilateral Interaction Between Everolimus and Rosuvastatin in Renal Transplant Recipients
Study Start Date : February 2012
Actual Primary Completion Date : October 2012
Actual Study Completion Date : October 2012

Arm Intervention/treatment
Experimental: Rosuvastatin
Rosuvastatin treatment for 4 weeks
Drug: Rosuvastatin
20 mg rosuvastatin for 4 weeks
Other Name: Crestor

Primary Outcome Measures :
  1. compare the treatment efficacy (blood lipid lowering effect) of rosuvastatin versus fluvastatin [ Time Frame: 4 weeks ]
    Compare the blood lipid levels before and after switch from fluvastatin to rosuvastatin

  2. Area Under Curve (AUC) of rosuvastatin in renal transplant recipients treated with everolimus. Time frame: predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24 hours post dose. [ Time Frame: 4 weeks ]
    Compare 24-h pharmacokinetics of renal transplant recipients with historic controls

Secondary Outcome Measures :
  1. 1. Area Under Curve (AUC) of everolimus during rosuvastatin versus fluvastatin therapy, including intracellular everolimus concentrations within T-lymphocytes. Time frame: predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours post-dose. [ Time Frame: 4 weeks ]
  2. 2. Investigate P-gp activity in whole blood in everolimus treated patients [ Time Frame: 4 weeks ]
  3. 3. Study inter individual variation in rosuvastatin and everolimus pharmacokinetics in renal transplant recipients due to polymorphism in the genes encoding P-gp, OATP1B1 and CYP3A5 [ Time Frame: 4 weeks ]
  4. 4. Compare effect of rosuvastatin versus fluvastatin therapy on the renal function (eGFR) [ Time Frame: 4 weeks ]
