Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
This study investigated the benefits and risks of long-term galantamine use in participants with Alzheimer's Disease. The study was conducted from 19 May 2008 to 20 May 2012 at 127 clinical centers in 13 countries. A total of 2051 participants were randomized to study treatment, of these 2045 received at least 1 dose of treatment.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The Data Safety Monitoring Board (DSMB) recommended that the study be terminated early because of an imbalance of deaths between the treatment groups.

Reporting Groups
  Description
Placebo During the titration and long-term maintenance periods, placebo was supplied as oral capsules matching galantamine capsules in size and appearance. The study drug was administered using the same titration and maintenance regimens as was used for participants in the galantamine treatment group.
Galantamine During the titration period (Days 1 to 84), participants received galantamine controlled-release oral capsules 8 mg/day for the first 4 weeks, followed by 16 mg/day for the next 4 weeks, then 24 mg/day for the next 4 weeks (based on tolerability). During the long-term maintenance period (Months 4 to 24), participants received galantamine at the dosage achieved at Day 84 of the titration period and continued until the completion of the Month 24 visit. A one-time dose titration to 16 or 24 mg/day was allowed, based on the investigator’s judgment and participant tolerability.
