Stem Cell Infusion for Alzheimer's Disease

Start: August 2016
End: September 2021
Enrollment: 30

What Is This Study About?

This Phase I trial will test the safety and efficacy of an infusion of Longeveron Mesenchymal Stem Cells (LMSCs) to treat people with Alzheimer's disease. Mesenchymal stem cells have been found to counteract the neuroinflammation that contributes to the progression of Alzheimers disease.
