Brief summary

Evaluation of central nervous system penetration of orally administered Rapamune (RAPA) in older adults with Mild Cognitive Impairment (MCI) or early Alzheimer's disease (AD) and investigate associated safety, tolerability, target engagement, cognition, and functional status as initial proof-of-concept study

Detailed description

This study is an open-label pilot study of orally administered RAPA to measure its target engagement in Cerebrospinal Fluid (CSF) and blood, and to establish the feasibility and safety of RAPA treatment in older adults with MCI and early stage AD as initial proof-of-concept for a larger Phase 2 clinical trial.
