History of Changes
  Purpose

Probands with MCI are at high risk to develop Alzheimer´s dementia (AD). Simvastatin may lower the production of Amyloid, a hallmark of AD in the brain. The primary hypothesis of the study is that Simvastatin significantly reduces the risk of conversion to Alzheimer's disease in individuals with MCI as compared to MCI receiving placebo.

Estimated Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo Drug: Placebo
one tablet once daily
Experimental: Simvastatin
Simvastatin 60 mg once daily
 Drug: Simvastatin
60 mg once daily

Detailed Description:

This is a national multicenter, double-blind, randomized placebo-controlled trial allowing for a minimum follow-up time of 24 months in conversion-free patients. Subjects will be randomly assigned to one of 2 treatment arms: (1) Simvastatin (60 mg) one tablet/day (2) Placebo one tablet/day.

  Eligibility

Ages Eligible for Study:   55 Years to 85 Years
Genders Eligible for Study:   Both

Criteria

Inclusion Criteria:

  1. Self and informant report of gradually increasing memory impairment for at least six months.
  2. Objective memory impairment
  3. Intact basic activities of daily living
  4. Preserved general cognitive function, not demented
  5. Absence of a detectable cause of memory disorder
  6. Age 55 to 85.
  7. Females without childbearing potential
  8. A total cholesterol ≥90 mg/dl
  9. LDL-cholesterol ≥ 160 mg/dl and ≤ 3 risk factors or ≥ 190 mg/dl and ≤ 2 risk factors including age
  10. Informed consent (according AMG §40 (1) 3b)
  11. No participation in other clinical trials 2 months before and after participation in this study
  12. Probands should only recruited for the clinical trial, when they are able to perform the informed consent; due to worsening of "memory function" in the course of the clinical trial, probands should not longer participate the clinical trial, when they is evidence, that participants were not longer able to give full informed consent.

Exclusion Criteria:

  5. Chronic use of anti-inflammatory drugs
  6. History of stroke or myocardial infarction
  7. LDL-cholesterol 130-160 mg/dl and > 3 risk factors or 160-190 mg/dl and > 2 risk factors including age.
  8. LDL-cholesterol >190 mg/dl
  9. Comedication with Diltiazem, Verapamil, Amiodarone, Itraconazole, Ketoconazole, Erythromycin, Clarithromycin, Telithromycin, Ciclosporin, Gemfibrozil, Nefazodone, HIV-protease inhibitors, Benzodiazepines, Tricyclic antipsychotics or other anticholinergic drugs
