About this study
Official title: Placebo-Controlled, Double-Blind Study of Galantamine (R113675) in the Treatment of Alzheimer's Disease.
The purpose of this study is to evaluate the efficacy and safety of two fixed doses (16mg/day and 24mg/day) of galantamine (a drug for treating dementia) versus placebo for the treatment of patients with Alzheimer's disease, and to investigate the dose-response.
Read the detailed description
This is a randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of two fixed doses of galantamine (16 and 24 milligrams per day [mg/day]) in patients with Alzheimer's disease, and to investigate the dose-response. The study consists of a 4-week screening period during which all patients will receive placebo, and a 22-week double-blind treatment period during which patients will receive placebo, galantamine 16 mg/day, or galantamine 24 mg/day. For patients receiving galantamine treatment, the starting dose is 8 mg/day and increases at 4-week intervals in increments of 8 mg/day. The primary measures of effectiveness are the change from baseline to the end of the study (week 22) in the Alzheimer's Disease Assessment Scale - Japan cognitive subscale (ADAS-J cog) and the Clinician's Interview-Based Impression of Change plus - Japan (CIBIC plus-J). Safety assessments include the incidence of adverse events, clinical laboratory tests, vital signs, electrocardiograms (ECGs), and physical examination findings. The study hypothesis is that galantamine will be more effective in the treatment of Alzheimer's disease than placebo. Study drug taken orally twice a day. 4-week screening period: All patients receive placebo. 22-week treatment period: Patients receive placebo, galantamine 16 mg/day, or 24 mg/day. For galantamine treatment, the starting dose is 8 mg/day and increases at 4-week intervals in increments of 8 mg/day.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing galantamine in people with Alzheimer Disease, run by Janssen Pharmaceutical K.K..
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 4 inclusion and 5 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 17 May 2011. 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?
Change from baseline to the end of the study in the Alzheimer's Disease Assessment Scale - Japan cognitive subscale (ADAS-J cog) and the Clinician's Interview-Based Impression of Change plus - Japan (CIBIC plus-J). 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 17 May 2011.
