Can stem cell mist heal lungs damaged by cancer immunotherapy?
NCT ID NCT07599111
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tests whether inhaling tiny particles from stem cells (exosomes) can help heal lung inflammation caused by immunotherapy drugs. The study involves 40 adults with cancer who have persistent lung problems despite standard steroid treatment. Participants will inhale either the exosome mist or a placebo twice daily for a week, and researchers will track lung healing and safety for 24 weeks.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- nebulized human umbilical cord mesenchymal stem cell-derived exosomes
- What this could lead to
- If it works, this could offer a new way to treat lung inflammation caused by immunotherapy, potentially reducing the need for steroids.
- What could go wrong
- This is a very early, small study (40 people) focused on safety. The treatment is experimental, and it may not improve lung lesions or could cause side effects.
