Study Description

Brief Summary:

This is a safety and tolerability study investigating the effect of HPP854 in subjects with mild cognitive impairment or a diagnosis of mild Alzheimer's disease. The study will assess the pharmacokinetic and pharmacodynamic relationships of HPP854 in plasma, pharmacodynamic relationship in cerebral spinal fluid and plasma concentration profiles for Amyloid-Beta.
