NCT ID NCT07312656
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests an oral spray made from stem cell exosomes to prevent severe mouth sores in head and neck cancer patients undergoing radiation. 200 participants will use the spray three times daily, starting a week before radiation and continuing for two weeks after. The goal is to see if it reduces the number of patients who develop painful, high-grade mouth ulcers.
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 cell-derived exosomes
What this could lead to
If it works, this could provide a new way to prevent painful mouth sores caused by radiation therapy, improving quality of life for head and neck cancer patients.
What could go wrong
This is a Phase 2 trial, so it is still early. The treatment may not reduce severe mouth sores more than standard care, and side effects from the exosome spray are not yet fully known.
