Umbilical cord stem cells tested as lung disease therapy
NCT ID NCT05147688
First seen Oct 16, 2026 · Last updated Oct 16, 2026
Summary
Researchers test whether intravenous infusions of donated umbilical cord or placental stem cells are safe for people with pulmonary diseases such as asthma and COPD. The trial enrolls 20 adults with a diagnosed lung condition. Participants receive the stem cell infusions, and doctors monitor for side effects and measure changes in lung function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cultured allogeneic adult umbilical cord or placental derived mesenchymal stem cells
- What this could lead to
- If it works, this could point toward a new cell-based treatment for chronic lung diseases like asthma and COPD.
- What could go wrong
- This is a small, early-stage safety trial, so it may not show any benefit. Stem cell infusions can cause immune reactions or other complications.
