  Purpose

Hypothesis : In renal transplantation recipient who received immunosuppressive drug "certican" and have hypercholesterolemia will get lipid lower drug-HMG Co-A reductase inhibitors. Because atorvastatin and everolimus have metabolism via Cytochrome P450 subfamily 3A4 both, so investigator made the hypothesis that when patients received everolimus with atorvastatin will change area under the time concentration curve of everolimus.

Primary Outcome Measures:
  • 12-hour area under the time concentration curve of everolimus [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    compare when taking only everolimus to coadministered with atorvastatin


Secondary Outcome Measures:
  • Renal function [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    Renal function : serum creatinine, 24 hour creatinine clearance 24 hour urine protein, Urinalysis Sample take at month 0,1,2,3

  • Liver function test [ Time Frame: 3 month ] [ Designated as safety issue: Yes ]
    Total protein, Albumin, total bilirubin, direct bilirubin, AST, ALT, Alkaline phosphatase at month 0,1,2,3

  • Lipid profile [ Time Frame: 3 month ] [ Designated as safety issue: Yes ]
    Total cholesterol, Triglyceride, HDL, LDL at month 0,1,2,3

  • Rhabdomyolysis [ Time Frame: 3 month ] [ Designated as safety issue: Yes ]
    Adverse drug reaction from atorvastatin by measured CPK at month 0,1,2,3


Other Outcome Measures:
  • Correlation of 12-hour AUC and point of everolimus level [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    To correlate between 12-hour AUC and point of everolimus level

Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: everolimus
Everolimus administration with adjusted dose to target C trough (C0) level between 3-12 ng/mL
Drug: Atorvastatin 20 mg
Add atorvastatin 20 mg and compare 12-hour AUC of everolimus between Arm everolimus and everolimus with atorvastatin 20 mg
Other Name: Lipitor 20 mg
Experimental: everolimus with atorvastatin 20 mg

Co-administration of everolimus and atorvastatin. Everolimus administration with adjusted dose to target C trough (C0)level between 3-12 ng/mL.

Atorvastatin 20 mg/day (fixed dose)

Drug: Everolimus
Administration only everolimus, no atorvastatin. Everolimus administration with adjusted dose to target C trough (C0)level between 3-12 ng/mL.
Other Name: Everolimus alone

Detailed Description:

Population : Thai postrenal transplantation recipient who received everolimus and have hypercholesterolemia in posttransplantation clinic at Faculty of Medicine, Chulalongkorn University.

Study Design : Experimental study, Two-sample crossover study Sample size calculation :N = 18 Primary outcome : 12-hour area under the time concentration curve of everolimus Secondary outcome : renal function (serum creatinine, creatinine clearance)

Method :

  1. Patients will random to everolimus or everolimus with atorvastatin 20 mg arm for 1 month.
  2. Take blood sample for everolimus concentration at time 0,0.5, 1, 1.5, 2, 2.5, 4, 6, 8, 12 hour
  3. After first blood sample, patients will received everolimus only for 1 month (wash out period)
  4. Patients will switch to another arm eg.patient who had received everolimus will switch to everolimus with atorvastatin 20 mg for 1 month
  5. Take blood sample for everolimus concentration at time 0,0.5, 1, 1.5, 2, 2.5, 4, 6, 8, 12 hour
  6. Everolimus level will analyse for 12-hour AUC of everolimus.
