Primary Outcome Measures:
  • Compare the effects of simvastatin + ezetimibe with those of simvastatin alone, on thrombogenic mechanisms, in patients with diabetes mellitus type 2. [ Time Frame: 6 weeks, 14-18 weeks, 22-24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Compare effects of simvastatin alone with those of placebo on thrombogenic mechanisms. Compare the effects of simvast. + ezetim. with those of simvast. alone on inflammatory variables. Assess how the treatment effect relate to renal function. [ Time Frame: 6 weeks, 14-18 weeks, 22-24 weeks ] [ Designated as safety issue: No ]

Enrollment: 39
Study Start Date: January 2006
Study Completion Date: June 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: simvastatin + ezetimibe
Cross-over study with placebo only run-in period. All patients participate in this arm with simvastatin + ezetimibe either as first treatment period (8-10 weeks)or second treatment period (8-10 weeks). The primary comparison is ezetimibe vs. placebo on top of simvastatin. A secondary comparison will be simvastatin vs. placebo run-in.
Drug: Ezetimibe
After a placebo only run-in period patients (two groups) are treated with simvastatin + ezetimibe and simvastatin + placebo in a cross-over trial. Ezetimibe effects on top of simvastatin will be evaluated as the primary aim; simvastatin effects compared to run-in on placebo will be evaluated as a secondary aim.
Other Names:
  • Simvastatin

  Eligibility

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diabetes mellitus type 1 or type 2
  • With or without established microalbuminuria (albumin-to-creatinine ratio (ACR)2,5-25 mg/mmol for men, and 3,5-25 mg/mmol for women, according to ISH and ESC recommended criteria)
  • Glomerular filtration rate (GFR) between 15-60 ml/min/1.73m2 (measured the last 6 months) or GFR >75ml/min/1.73m2. The abbreviated Modification of Diet in Renal Disease (MDRD) equation will be used to calculate GFR.
  • Age 18-80 years

Exclusion Criteria:

  • Definite history of myocardial infarction, coronary revascularisation procedure or stroke. (i.e, a strong clinical indication for statin treatment)
  • Functioning renal transplant, or living donor-related transplant planned.
  • Patients on dialysis.
  • Poor metabolic control, i.e HbA1c > 9%
  • Definite history of chronic liver disease, or abnormal liver function (i.e ALT >1,5 x ULN or, if ALT not available, AST > 1,5 x ULN).
  • Evidence of active inflammatory muscle disease (e.g dermatomyositis, polymyositis), or CK>3 x ULN;
  • Definite previous adverse reaction to a statin or to ezetimibe
  • Definite previous adverse reaction to acetylsalicylic acid.
  • Definite previous adverse reaction to an ACE-inhibitor.
  • Need for concomitant treatment with a strong inhibitor of CYP3A4, such as itrokonazole, ketokonazole, erythromycin, clarithromycin, HIV-protease inhibitors or nefazodone (i.e. agents that may markedly elevate simvastatin levels).
