Could a common antibiotic help fight MS by changing gut bacteria?
NCT ID NCT05539729
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study is testing whether the antibiotic vancomycin can change the gut bacteria and immune system of people with newly diagnosed multiple sclerosis (MS). The researchers will give vancomycin or a placebo to 12 people and measure changes in gut bacteria, blood markers, and brain scans. The goal is to understand how gut bacteria might affect MS, not to find a treatment yet.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
vancomycin
What this could lead to
If it works, this could point toward a way to treat MS by targeting gut bacteria.
What could go wrong
This is a very small, early-phase study with only 12 people. It is designed to test a theory, not to prove a treatment works.
