Stem cells injected into gut to fight Crohn's – but trial stops early

NCT ID NCT04548583

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase study tested whether injecting donor stem cells directly into the colon could help people with severe Crohn's colitis that didn't respond to standard treatments. Only 7 people took part before the study was stopped early. The main goal was to check safety, but because it was so small and unfinished, we can't draw firm conclusions about how well it works.

What this could mean

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

Active substance

Remestemcel-L (stem cells from a donor's bone marrow)

What this could lead to

If it works, this could point toward a new way to treat severe Crohn's colitis without surgery.

What could go wrong

This was a very small, early-phase trial that was terminated early, so we don't know if it's safe or effective. Stem cell treatments can have unknown long-term risks.
