Memantine is a therapeutic agent that represents a unique class of Alzheimer's disease (AD) treatment options. A once daily (QD) dosing regimen in an AD population would simplify administration for the caregiver. The purpose of this study is to evaluate the safety and efficacy of modified release memantine taken once daily in outpatients with moderate-to-severe AD on a concurrent AChEI.
The objective of this study is to evaluate the safety, tolerability, and efficacy of memantine compared to placebo in outpatients diagnosed with moderate-to-severe dementia of the Alzheimer's type on a concurrent acetylcholinesterase inhibitor (AChEI).
