Safety and Tolerability of Etanercept in Alzheimer's Disease
A Phase 2, Double-blind, Placebo-controlled Study of the Safety and Tolerability of Etanercept in Patients With Alzheimer's Disease

The primary aim of the study is to determine the safety and tolerability of etanercept in subjects with Alzheimer's Disease. The effects of etanercept on cognitive, behavioural, functional and immunological outcomes will be examined as secondary aims.
