About this study
Official title: A Randomized, Double Blind, Active Control, Flexible Dose, Multicenter Study to Evaluate Galantamine HBr in the Treatment of Alzheimer's Disease:Safety and Effectiveness of an Immediate-release Table Formulation.
The purpose of this randomized, double-blind, active-controlled, flexible dosage, multicenter study is to evaluate the effectiveness and safety of galantamine tablet (16-24mg/day) for 16 weeks in the treatment of mild to moderate Alzheimer's Disease (AD) comparing with Donepezil.
Read the detailed description
This is a randomized, double-blind, active-controlled, flexible dosage, multicenter study to evaluate the effectiveness and safety of galantamine tablet in the treatment of mild to moderate AD. The comparator is Donepezil tablet. At least 206 patients were to be randomized in the study. The study consisted of 3 phases: a screening phase, a single-blind run-in phase and a double-blind treatment phase. Screening phase is less than 2 week for eligible assessment; If the patient was taking any anti-dementia drug at screening, he/she had to stop these drugs and enter into the single-blind run-in phase. The patient who did not take any anti-dementia drug can enter into baseline directly. During the single-blind run-in phase, all eligible patients will take placebo twice daily for 4 weeks. Double-blind treatment phase is 16 weeks. At baseline, all patients who are still eligible for inclusion/exclusion criteria will be randomized to either galantamine group or donepezil group at 1:1 ratio, drugs will be taken twice daily by a flexible dose for 16 weeks. Dose will be titrated during the first 9-12 weeks. Dose will be fixed to 16mg/day or 24mg/day based on tolerability of the patient judged by the investigator. The primary effectiveness endpoint is changes in ADAS-cog/11 at week 16 from baseline, secondary endpoint is responder rate in term of ADAS-cog/11. Safety evaluation included adverse events, physical examination, ECG, and safety laboratory tests. Study drug are taken orally twice a day. The treatment duration was 16 weeks. Initial galantamine dose is 8 mg/day, dose was increased to 16mg/day at week 5 and to 24 mg/day at week 9. At week 12, dose was fixed to either 16mg/day or 24mg/day at the discretion of investigators. Initial donepezil dose is 5mg/day, dose was then increased to 10mg/day at week 9. At week 12, dose was fixed to either 5mg/day or 10mg/day at the discretion of investigators.

What is being measured
The primary outcome is the main question the study is designed to answer.
Primary endpoint (ADAS-cog/11) decreased 5.4 ± 6.4 and 4 .0 ± 7.3 in galantamine and Donepezil group respectively after 16-week treatment from baseline of 22.5 ± 9.3 and 23.3 ± 9.7 respectively, showing the non-inferiority in term of efficacy.
Secondary outcomes (1)
Secondary endpoint is responder rate. It showed 78% responder rate in galantamine group and 58% responder rate in Donepezil group after 16 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Galantamine HBr in people with Alzheimer Disease, run by Xian-Janssen Pharmaceutical Ltd..
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 3 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 19 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?
Primary endpoint (ADAS-cog/11) decreased 5.4 ± 6.4 and 4 .0 ± 7.3 in galantamine and Donepezil group respectively after 16-week treatment from baseline of 22.5 ± 9.3 and 23.3 ± 9.7 respectively, showing the non-inferiority in term of efficacy.. 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 19 May 2011.
