Efficacy and Safety of Rivastigmine Transdermal Patch in Patients With Mild to Moderate Alzheimer's Disease

Alzheimer's Disease Clinical Trial

Official title: A 24-week, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group, Dose-finding Evaluation of the Efficacy, Safety, and Tolerability of the Once-daily Rivastigmine Transdermal Patch in Patients With Probable Alzheimer's Disease (MMSE 10-20)

Status Completed

Clinical Trial Summary

The purpose of this study was to investigate the 5cm^2 and 10cm^2 doses of rivastigmine transdermal patch in terms of efficacy and safety in patients with probable Alzheimer's Disease (MMSE [Mini Mental State Examination] 10-20). A 52-week extension phase evaluated the safety and tolerability of long-term treatment by rivastigmine transdermal patch in patients with probable Alzheimer's Disease (AD).

Clinical Trial Description

Patients were randomly assigned in a double-blind manner to one of the 3 treatment arms (placebo, rivastigmine 5 cm^2 and rivastigmine 10 cm^2) in a ratio of 1:1:1. During the Double-blind treatment phase, patients entered a 16-week Titration Period followed by an 8-week Maintenance Period. During the open-label extension phase, all patients started treatment with a 2.5 cm^2 patch and the dose was increased to 10 cm^2 over a 16-week titration period, followed by a maintenance period of 36 weeks. ;
