Can stem cell vesicles heal Crohn's fistulas?

NCT ID NCT05836883

First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time

Summary

This early-phase trial tests whether ExoFlo, a product made from extracellular vesicles derived from donor bone marrow stem cells, can safely treat perianal fistulas in people with Crohn's disease. The study enrolls adults aged 18-75 who have had Crohn's for at least six months and have failed at least one prior medical therapy. Participants receive a local injection of ExoFlo or a placebo, and the main goal is to assess safety and feasibility.

What this could mean

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

Active substance
ExoFlo, an injection of extracellular vesicles derived from donor bone marrow stem cells
What this could lead to
If safe and effective, ExoFlo could offer a new way to heal perianal fistulas in Crohn's disease, potentially reducing the need for surgery or long-term immune-suppressing drugs.
What could go wrong
This is a very early, small trial (only 5 participants) focused on safety and feasibility, so it may not show clear benefit. Risks include injection-site reactions or lack of effectiveness.
