NCT00000174

Brief Summary

This phase IIIb trial is a prospective, randomized, double-blind, placebo-controlled, 36-month study comparing the length of time of progression from mild cognitive impairment (MCI) to a clinical diagnosis of Alzheimer's disease (AD) in subjects taking Exelon vs. placebo. Exelon is currently under review with the U.S. Food and Drug Administration as a treatment for Alzheimer's disease. The drug has been cleared for marketing in more than 40 countries for Alzheimer's disease to date, including all 15 member states of the European Union, New Zealand, Argentina, Brazil and Mexico. Each subject with MCI will be randomly assigned to treatment with either Exelon or placebo. Subjects assigned to Exelon will receive 1.5 to 6.0 mg bid (twice daily) (3.0 to 12 mg/day) for the majority of the study. At every regular visit scheduled every three months, patients will be given basic efficacy and safety assessments. These assessments will include evaluation of adverse events, vital signs, activities of daily living, and clinical staging scales to determine if the subject may have converted to dementia.

Eligibility Criteria

Age55 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Are aged 55-85 years, inclusive. Subjects older than 85 years may be eligible to participate, with approval of the designated study medical monitor.
  • Are male or female without child-bearing potential (i.e., surgically sterilized \[via bilateral tubal ligation,bilateral oophorectomy, or hysterectomy\], at least one year postmenopausal, or using adequate birth control).
  • Are cooperative, able to ingest oral medication, and willing to complete all aspects of the study.
  • Will provide written informed consent prior to their participation in the study.
  • Show evidence of mild cognitive impairment (MCI) by meeting all of the following criteria: Global CDR score = 0.5, NYU Delayed Paragraph Recall less than 9, 17-item HAM-D score less than 13, and HAM-D Item 1 (depressed mood) score =1.
  • Have a friend or family member who is willing to participate in the study as an informant. The informant must see the subject at least once a week for several hours and be available to accompany the subject to the screening and baseline visits, and at a minimum, be accessible by telephone for other scheduled visits.

You may not qualify if:

  • Advanced, severe, and unstable disease of any type that may interfere with primary and secondary variable evaluations including any medical condition that could be expected to progress, recur, or change to such an extent that it may bias the assessment of the clinical or mental status of the subject to a significant degree or put the subject at special risk.
  • Cognitive impairment sufficient to warrant a diagnosis of dementia.
  • Met the DSM-IV and NINCDS-ADRDA criteria for AD.
  • A clinical diagnosis of AD.
  • A DSM-IV Axis 1 diagnosis. However, subjects with current depression are eligible after appropriate treatment of the depressive episode. A minimum of four weeks washout of antidepressant medication should occur prior to screening. Subjects with a prior history of depression (but not currently depressed) are allowed in the study.
  • Fewer than four years of formal education.
  • A documented history of transient ischemic attacks.
  • Baseline MRI findings or CT-scan findings within a year of screening that are consistent with a process other than AD, e.g., stroke, tumor, brain trauma or hydrocephalus, that may contribute to the subject's MCI. Lacunae infarcts present in areas affecting cognition (entorhinal cortex, hippocampus, medial temporal lobe) will also exclude the subject from the study.
  • A score of greater than 4 on the Modified Hachinski Ischemic Scale.
  • A current diagnosis of any primary neurodegenerative disorder, e.g., Parkinson's disease.
  • A current diagnosis of uncontrolled seizure disorder.
  • A current diagnosis of active peptic ulceration.
  • A current diagnosis of severe and unstable cardiovascular disease.
  • A current diagnosis of sick-sinus syndrome or conduction deficits (sino-atrial block, second or third degree atrio-ventricular block).
  • A current diagnosis of acute, severe, or unstable asthmatic conditions.
  • +9 more criteria
