A Double-Blind, Placebo-Controlled, Dose Ranging Study of Xanamem® in Healthy Elderly Volunteers

XanaMIA-DR a Double-Blind, Placebo-Controlled, Dose Ranging Study to Assess the Efficacy, Pharmacodynamics and Safety of Xanamem® in Healthy Elderly Volunteers

Xanamem® is being developed as a potential drug for Mild Cognitive Impairment in Alzheimer's disease. This study drug has been designed to change the cortisol levels in the brain. Cortisol is a naturally occurring hormone in the body. It is believed that reducing the level of cortisol will be a benefit in the treatment of Mild Cognitive Impairment in Alzheimer's disease.

The purpose of this study in older volunteers is to investigate the smallest dose of Xanamem® (5 mg or 10 mg) which works and to investigate which dose in this study will be used in the upcoming clinical trials in patients.
