About this study
Official title: A European Multi-Center Study to Determine the Safety and Efficacy of Galanthamine Hydrobromide 40mg/Day (32 mg /Day GAL Base, Tid Dose Regimen) in Patients Diagnosed With Alzheimer-Type Dementia
The purpose of this study was to determine the safety and effectiveness of a relatively high dose of galantamine, 32 mg /day in a three-times daily dosage, compared with placebo in treating patients with Alzheimer's disease.
Read the detailed description
Alzheimer's disease is a progressive degenerative brain disorder that affects memory, as well as the ability to concentrate, reason, and think in abstract form. This study was designed to examine the effectiveness and safety of galantamine (galant.) hydrobromide at a relatively high dose, compared with treatment with placebo, in men and women with Alzheimer's disease. Approximately 600 patients were screened. This was a double-blind study, i.e., neither patients nor investigators knew what treatment was given. Before the start of the double-blind phase, each patient was randomly assigned to receive either galantamine hydrobromide or placebo (i.e., no active drug). The dose was increased weekly, at a higher rate than currently recommended in the label, until the stable daily dose of 32 mg galantamine was reached. All patients took their treatment (galantamine or placebo) 3 times a day. All patients who completed the blinded phase of the study were permitted to enter an open-label phase, in which the treatment was made known to both investigators and patients. During this additional 24-week phase, all patients received treatment with galantamine hydrobromide. The effectiveness of study treatment (galantamine hydrobromide or placebo) was assessed using several measures and included the Mini Mental State Examination (MMSE) score. The MMSE consists of 12 questions and tasks designed to assess severity of Alzheimer's disease. Additional measures included the European Alzheimer Disease Assessment Scale cognitive score (EURO-ADAS-cog), a Clinician's Interview Based Impression of Change (CIBIC) plus, and the Nurses' Observation Scale for Geriatric Patients (NOSGER). Safety and tolerability were assessed using physical (full and brief) examination, adverse events reports, clinical and laboratory measures, and 12-lead ECG results. Galant. was taken orally as a tablet 3 times a day with meals. Patients started their treatment with a total 8 mg of galantamine. The dose was increased weekly to a daily cumulative dose of 32 mg (the same as 40 mg Gal HBr).This dose was higher and the titration schedule was 4 times more rapid that the 16 mg and 24 mg maintenance doses and 4-weekly titration steps specified in the US label. Each phase had a 5-week titration period. After 5 weeks, patients continued to receive 40 mg.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary outcomes included evaluations by EURO-ADAS cognitive score, CIBIC Plus, and NOSGER at 6 months.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2010.
