Fat-Derived stem cells injected into Alzheimer's patients in new safety trial
NCT ID NCT07367815
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial is testing whether stem cells taken from donated fat tissue are safe when given through an IV to people with mild to moderate Alzheimer's disease. Nine participants will receive increasing doses of the cells and be monitored for side effects over six months. The study also looks at whether the treatment affects inflammation in the body and brain.
