Could a common drug protect the brain from Alzheimer's?

NCT ID NCT05386914

First seen Mar 17, 2026

Summary

This early study tests whether sirolimus, an FDA-approved drug, can improve blood flow to the brain in healthy adults with a genetic risk for Alzheimer's disease. Researchers will use MRI scans to measure changes after 4 weeks of daily low-dose sirolimus. The study also explores how lung function relates to brain blood flow. It involves 205 cognitively normal adults aged 45-65.

Active substance

sirolimus

What this could lead to

If it works, this could point toward a way to improve brain blood flow in people at risk for Alzheimer's disease.

What could go wrong

This is a very early Phase 1 study with only 4 weeks of treatment. It is not designed to test whether sirolimus prevents or treats Alzheimer's, only whether it changes blood flow.
