Poop pills or tubes: could fecal transplants tame deadly transplant complication?
NCT ID NCT07602751
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether giving fecal microbiota (from a healthy donor) via a tube or scope into the gut can safely help children and young adults with severe intestinal graft-versus-host disease that hasn't improved with steroids. About 20 participants aged 3 months to 25 years will receive 1 to 3 treatments. The main goal is to check safety, but researchers will also see if it helps control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- fecal microbiota transplantation
- What this could lead to
- If successful, this could offer a new treatment option for severe gut graft-versus-host disease that doesn't respond to steroids.
- What could go wrong
- This is an early-phase pilot study with only 20 participants, so results may not apply broadly. Risks include infection or complications from the procedure.
