Primary Outcome Measures:
  • Change from baseline to end of double-blind treatment in ADAS-cog/11 (Alzheimer's Disease Assessment Scale: sum of 11 cognitive items) and CIBIC-plus (Clinician's Interview Based Impression of Change - Plus Caregiver Input) scores

Secondary Outcome Measures:
  • Change from baseline to the end of double-blind treatment in ADAS-cog/13, NPI, and DAD scores; Change in ADAS scores from baseline to end of open-label treatment; Incidence of adverse events; Changes in laboratory tests, ECGs and physical examinations

Enrollment: 593

Study Completion Date: December 2000
Detailed Description:

This multicenter, double-blind, placebo-controlled study will evaluate the safety and effectiveness of galantamine in patients with dementia related to cerebrovascular disease or related to Alzheimer's disease with cerebrovascular disease ("mixed" dementia). All patients will initially receive placebo for a 1-month period and then will receive galantamine (starting at a low dose and gradually increasing over 5 weeks to 12 mg twice daily) or placebo for 6 months. The primary measures of effectiveness include the change from baseline to the end of treatment in the ADAS-cog/11 score (Alzheimer's Disease Assessment Scale: sum of 11 cognitive items) and the CIBIC-plus score (Clinician's Interview Based Impression of Change - Plus Caregiver Input). Additional measures of effectiveness include the change from baseline to the end of the treatment in the ADAS-cog/13 score (Alzheimer's Disease Assessment Scale: sum of 13 cognitive items), the Disability Assessment for Dementia (DAD) score, and the Neuropsychiatric Inventory (NPI)) score. Safety evaluations (incidence of adverse events, electrocardiograms (ECGs), physical examinations, laboratory tests) will be performed throughout the study. Patients who complete the double-blind portion of the study will have the opportunity to participate in a 6-month open-label extension study in which they will receive galantamine for an additional 6 months. Effectiveness will be assessed after 6 weeks, 3 months and 6 months of open-label treatment. Safety evaluations (incidence of adverse events, ECGs, physical examinations, laboratory tests) will be performed throughout the open-label portion of the study. The study hypothesis is that galantamine will be effective in the treatment of patients with vascular or mixed dementia and will be well tolerated. Double-blind: Galantamine 12 mg or placebo by mouth twice daily for 6 months, starting at a low dose and gradually increasing over 5 weeks to the final dose; Open-label: galantamine 12 mg by mouth twice daily, starting at a low dose and gradually increasing over 6 weeks to the final dose.
