Study of the Effect of SR57667B in Patients With Alzheimer's Disease

Phase 2
Completed
Conditions
Alzheimer Disease
Registration Number
NCT00285025
Lead Sponsor
Sanofi
Brief Summary

The primary objective is to demonstrate that SR57667B at the dose of 4 mg/day, in comparison to placebo, decreases the decline in cognitive performance and the global clinical decline over 1 year in patients with mild to moderate AD.

Secondary objectives are to assess the effect of SR57667B on functional decline and its safety/tolerability in patients with mild to moderate AD, and to document plasma concentrations of SR57667 in patients with mild to moderate AD.

Detailed Description

Multinational, multicenter, randomized, parallel-group, double-blind, phase II study
