What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Summary

This pilot study is testing whether metformin, a common diabetes drug, can safely protect the nervous system in people aged 55 to 75 with multiple sclerosis (MS). Thirty participants will receive either metformin or a placebo for 9 months, and researchers will use brain scans to measure nerve health. The goal is to see if metformin can slow age- and MS-related brain damage.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
metformin
What this could lead to
If it works, this could point toward a new way to protect the brain from age- and MS-related damage in older patients.
What could go wrong
This is a small, early pilot study with only 30 participants, so results may not apply to everyone. Metformin may also cause side effects like stomach upset.
