Brief Title  ICMJE A Study of the Safety and Effectiveness of Two Doses of Galantamine Versus Placebo in the Treatment of Patients With Alzheimer's Disease
Official Title  ICMJE Efficacy, Tolerability and Safety of Galantamine in the Treatment of Alzheimer's Disease
Brief Summary The purpose of this study is to evaluate the safety and effectiveness of two doses of galantamine (a drug for treating dementia) versus placebo in the treatment of patients with Alzheimer's disease.
Detailed Description Dementia is a chronic, progressive brain disease that may involve a number of symptoms, including memory loss and changes in personality, behavior, judgment, attention span, language and thought. The most common type of dementia is Alzheimer's disease. Over time, patients with Alzheimer's disease may lose ability to perform daily tasks related to personal care (for example, bathing, dressing, and eating) and may be unable to handle money or travel to familiar places. Several small clinical trials have shown galantamine to be safe and effective in treating the symptoms associated with Alzheimer's disease. Doses studied have ranged from 15 - 60 mg/day, with galantamine administered two or three times daily. Additional information is needed to determine the optimal dose regimen for galantamine in the treatment of Alzheimer's disease. This multicenter, double-blind, placebo-controlled study evaluates the safety and effectiveness of two doses of galantamine, each given twice daily, in the treatment of patients with Alzheimer's disease. All patients initially receive placebo for a 1-month period and then receive one of two doses of galantamine (beginning with 4 mg twice daily and gradually increasing to 12 or 16 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 (Clinician's Interview Based Impression of Change - Plus Caregiver Input) score. Additional measures of effectiveness assessed at the end of the treatment include the ADAS-cog/13 score (Alzheimer's Disease Assessment Scale: sum of 13 cognitive items) and the Disability Assessment for Dementia (DAD) score. Safety evaluations (incidence of adverse events, electrocardiograms (ECGs), physical examinations, laboratory tests) are performed throughout the study. Caregiver quality of life (Psychological General Well Being Index, (PGWB)) and health/social care resource utilization (physician and other health care professional visits, use of social services, etc.) is also assessed throughout the study by questionnaires answered by the caregivers. Blood samples are taken throughout the study to determine the concentration of drug in the blood. Patients may participate in an optional portion of the study in which their genetic material is analyzed to see if contains something that would affect the way galantamine is used by their bodies. The study hypothesis is that galantamine administered in either dose is effective in the treatment of Alzheimer's disease as compared with placebo, and is well tolerated. This study will be conducted in the United States. A companion study of exact design will be conducted internationally. Galantamine, 12 or 16 mg tablets (or placebo), by mouth twice daily for 6 months, beginning with 4 mg twice daily and gradually increasing to 12 or 16 mg twice daily.
