Can donated umbilical cord stem cells calm multiple sclerosis?
NCT ID NCT05003388
First seen Oct 20, 2026 · Last updated Oct 21, 2026 · Updated 1 time
Summary
Researchers are testing whether an intravenous infusion of mesenchymal stem cells, taken from donated umbilical cord or placental tissue and grown in the lab, is safe for people with multiple sclerosis. The trial enrolls about 15 adults with a confirmed diagnosis. Participants receive the cell infusion and doctors track them for side effects, while also measuring disability with a standard neurological scale to see whether the approach shows any early signs of helping.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mesenchymal stem cells from donated umbilical cord or placental tissue
- What this could lead to
- If it works, this could point toward a new cell therapy that calms the immune attack in multiple sclerosis and helps preserve nerve function.
- What could go wrong
- This is a very small, early-stage safety trial, so most questions about benefit will remain open. Stem cell infusions can trigger immune reactions or infections, and the trial excludes people with active infections or cancer.
