May 18, 2011 updated by: Xian-Janssen Pharmaceutical Ltd.

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
215

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Secondary endpoint is responder rate. It showed 78% responder rate in galantamine group and 58% responder rate in Donepezil group after 16 weeks.
