Benfotiamine for early Alzheimer's disease in a Phase II trial
Official title: Phase II randomized controlled trial of benfotiamine in early Alzheimer's Disease
Funded at Weill Medical Coll of Cornell Univ · NIH-11595743 · Data updated 2026-11-12
A first-in-class blood-brain barrier form of vitamin B1 (benfotiamine) is being tested in people with early Alzheimer’s disease to see if it can help memory and thinking.

Who could benefit from this research
✓Could help
Adults with early Alzheimer's disease who meet study criteria and can participate in an 18-month randomized trial.
✕Less likely to help
People with advanced dementia or conditions that exclude trial participation may not benefit from this study.
What this research studies
This study continues an 18-month, randomized, placebo-controlled trial of benfotiamine for individuals in the early stages of Alzheimer’s disease. Researchers believe that boosting thiamine levels in the brain may improve metabolism, reduce brain inflammation, and lessen plaque and tangle pathology, potentially translating to better daily thinking and memory. The study builds on prior pilot data showing good tolerance and hints of cognitive benefit and aims to confirm these signals with more participants across a longer duration. Participants will receive either benfotiamine or placebo, with regular assessments of cognition, brain imaging, and biomarkers. If successful, this approach could become a new, safe oral treatment to slow progression in early Alzheimer’s disease.
Why it matters
Potential benefit: If successful, benfotiamine could slow cognitive decline and improve quality of life for people with early Alzheimer’s disease.
How similar studies have gone: Prior early-phase data suggested tolerability and potential cognitive benefits, supporting a larger Phase II/IIb trial.
