A4 Study

Study Type

Cognitive Impairment & Alzheimer's Disease

Study Purpose

The A4 research study will test whether an investigational medication (Solanezumab) can slow down memory loss and prevent the development of Alzheimer’s disease.

About the Study

Scientists believe a buildup of protein in the brain (called “amyloid plaque deposits”) may play a key role in the memory loss related to Alzheimer’s disease. The A4 study will observe whether decreasing amyloid plaque deposits, through the use of an investigational medication, can help slow memory loss and prevent the development of Alzheimer’s disease.
