Efficacy, Safety, & Tolerability of AZD3480 Patients With Mild to Moderate Dementia of the Alzheimer's Type (AD)

• Status: Completed
• Trial end date: 2014-05-01
• Target enrollment: 0
• Participant gender: All

Summary

Alzheimer's disease is the most common form of dementia and is the fourth leading cause of death among people 65 years of age and older. The global prevalence of the disease will increase significantly as the population ages, unless preventative treatments can be identified and marketed. The present study seeks to evaluate AZD3480 (TC-1734) compared to an approved medication (donepezil) shown to improve cognition and function in patients with Alzheimer's disease.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Targacept Inc.
• Treatments: Donepezil
