Trial of Simvastatin in Amnestic Mild Cognitive Impairment (MCI) Patients - Full Text View

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 60 mg Simvastatin significantly reduces the Clinical Dementia Rating -Sum of boxes (CDR-SOB) in individuals with MCI as compared to MCI receiving placebo or 20 mg Simvastatin

Primary Outcome Measures:

Change in CDR-SOB at 24 months of treatment [ Time Frame: 24 month ]
Clinical dementia rating - sum of boxes

Secondary Outcome Measures:

Change in Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog) score [ Time Frame: 24 month ]
Change in Free and Cued Selective Reminding Test (FCSRT) score [ Time Frame: 24 month ]
Length of conversion-free interval, starting at the time of randomization, with conversion being defined as an increase of the CDR score beyond 0.5 [ Time Frame: 24 months ]


Estimated Enrollment:	520
Study Start Date:	December 2008
Estimated Study Completion Date:	March 2019
Estimated Primary Completion Date:	October 2018 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Placebo Comparator: Placebo Placebo or 20 mg Simvastatin (stratified by prior use of statins)	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. Randomization will be stratified by prior use of statins.

The two strata are:

"no-statins": patients without treatment with a statins and no indication for treatment (according to the guidelines of the German Society of Cardiology for the primary prevention of cardiovascular disease); patients will be randomly assigned to one of 2 treatment (1) Simvastatin (60 mg) one tablet/day (2) Placebo one tablet/day.
"low-statins": patients treated with low doses of Statins; patients will be randomly assigned to one of 2 treatment (1) Simvastatin (60 mg) one tablet/day (2) 20 mg Simvastatin one tablet/day.

Eligibility


Ages Eligible for Study:	55 Years to 90 Years (Adult, Senior)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Self and informant report of gradually increasing memory impairment for at least six months.
Objective memory impairment
Intact basic activities of daily living
Preserved general cognitive function, not demented
Absence of a detectable cause of memory disorder

Informed consent (according german medicinal products act, AMG §40 (1) 3b)
No participation in other clinical trials 2 months before and after participation in this study
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:

History of stroke or myocardial infarction
LDL-cholesterol 130-160 mg/dl and > 3 risk factors or 160-190 mg/dl and > 2 risk factors including age.
LDL-cholesterol >190 mg/dl
Comedication with Diltiazem, Verapamil, Amiodarone, Itraconazole, Ketoconazole, Erythromycin, Clarithromycin, Telithromycin, Ciclosporin, Gemfibrozil, Nefazodone, HIV-protease inhibitors, Benzodiazepines, Tricyclic antipsychotics or other anticholinergic drugs
Comedication of other statins in high doses; low doses equivalent to 20 mg Simvastatin are allowed if taken for max. 2 years before randomization
