A Study of the Safety and Effectiveness of Galantamine Hydrobromide in Patients With Alzheimer's Disease
The purpose of this study is to evaluate the safety and effectiveness of galantamine hydrobromide in patients with Alzheimer's disease who have not received or have not responded to treatment with medication similar to galantamine hydrobromide.
|Study Design:||Time Perspective: Prospective|
|Official Title:||Open Observational Study of Galantamine Hydrobromide Administration for the Treatment of Patients With Mild to Moderate Dementia of the Alzheimer Type|
- Changes from baseline in Mini-Mental State Examination (MMSE) scale scores [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]The MMSE is a brief 30-point questionnaire test that is used to screen for cognitive impairment. A score greater than or equal to 25 points is effectively normal (intact). Below this, scores can indicate severe (≤9 points), moderate (10-20 points) or mild (21-24 points) cognitive impairment.
- Changes from baseline in Disability Assessment for Dementia (DAD) scale scores [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]The 40-item DAD scale assesses functional abilities in activities of daily living in patients with dementia and other cognitive impairments. Higher scores indicate less disability while lower scores denote more difficulties.
- Changes from baseline in Neuropsychiatric Inventory (NPI) scale scores [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]The NPI assesses psychopathology in dementia patients. It evaluates 12 neuropsychiatric disturbances common in dementia: delusions, hallucinations, agitation, dysphoria, anxiety, apathy, irritability, euphoria, disinhibition, aberrant motor behavior, night-time behavior disturbances, and appetite and eating abnormalities. Both the frequency (from rarely to very often) and the severity (from mild to severe) of each behavior are determined.
- Changes from baseline in Clinical Global Impression (CGI) scale scores [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a patient. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill patients".
- Changes from baseline in Cornell Scale [ Time Frame: Baseline to 6 months ] [ Designated as safety issue: No ]The Cornell Scale assesses signs and symptoms of major depression in patients with dementia. Each item is rated for severity on a scale of 0-2 (0=absent, 1=mild or intermittent, 2=severe). The item scores are added. Scores above 10 indicate a probable major depression. Scores above 18 indicate a definite major depression. Scores below 6 as a rule are associated with absence of significant depressive symptoms.
- Number of patients with Adverse Events as Measure of Safety and Tolerability [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Number of patients whose vital signs fell outside the normal ranges [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Number of patients whose laboratory test results fell outside the normal ranges [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Drug: Galantamine hydrobromide
247 patients with diagnosed mild to moderate Alzheimer disease.
Galantamine hydrobromide is a medication that is approved for the treatment of symptoms of Alzheimer's disease. In accordance with international guidelines, studies are conducted after a drug is marketed to continue to evaluate and expand the knowledge regarding its safety. This is a multi-center, open-label (all people involved know the identity of the intervention), observational study (individuals are observed or certain outcomes are measured - no attempt is made to affect the outcome) to collect information regarding the safety and effectiveness of galantamine hydrobromide in patients with Alzheimer's disease. Patients who have been prescribed galantamine hydrobromide as initial treatment with this type of medication for their Alzheimer's disease or who have failed previous treatment with similar medication of this type for their Alzheimer's disease will receive galantamine hydrobromide for 6 months. The individual physicians responsible for the treatment of Alzheimer's disease will administer galantamine hydrobromide at doses appropriate for each patient and will continue to oversee their care. No medication will be supplied by the sponsor of this study. Safety evaluations (incidence of adverse events, physical exams, vital signs and laboratory tests) will be performed throughout the study. Effectiveness will be determined using standard tests and rating scales to assess mental status, functioning, thinking, behavior, judgment and language (Neuropsychiatric Inventory, [NPI], Mini Mental Status Exam [MMSE] and Clinical Global Impression-Caregiver [CGI-Caregiver]). Assessments will be conducted monthly for the first 3 months and at the end of 6 months of treatment. Galantamine hydrobromide treatment should be discontinued if there is no further indication of effectiveness. At the end of the study, the treating physician may continue treatment with galantamine hydrobromide in responding patients as appropriate. The study hypothesis is that galantamine hydrobromide will be effective in treating the symptoms associated with Alzheimer's disease and is safe and well-tolerated. Observational study -No investigational drug administered
