NCT ID NCT06256614
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study is testing whether transplanting gut bacteria from healthy donors into people with type 1 diabetes can help control blood sugar and reduce insulin needs. Fifty participants will receive three doses of washed microbiota through the gastrointestinal tract. Researchers will track daily insulin use and time spent in target blood sugar range to see if the treatment is safe and effective.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
washed microbiota from healthy donors
What this could lead to
If it works, this could offer a new way to help manage type 1 diabetes by improving blood sugar control and reducing the amount of insulin needed.
What could go wrong
This is a small, early real-world study with only 50 participants, so results may not apply to everyone. The treatment involves infusing donor bacteria into the gut, which carries unknown risks and may not provide lasting benefits.
