Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is compare the effects of simvastatin+ezetimibe with those of simvastatin alone on platelet activity, platelet-leukocyte interactions and inflammatory variables in diabetic patients with or without impaired renal function.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Ezetimibe

Intervention Type DRUG

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.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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).
