Brief Summary:
The purpose of this trial is to assess the efficacy and safety of S47445 versus placebo in patients with Alzheimer's disease at mild to moderate stages with depressive symptoms. An optional 28-week extension period will be performed to evaluate safety/tolerance and efficacy of S47445 in co-administration with donepezil.
