UV light zaps mouth sores in transplant patients?
NCT ID NCT00374257
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether shining a special UV light inside the mouth could help people with painful mouth sores caused by graft-versus-host disease after a stem cell transplant. Only 11 people took part, and the study was stopped early. The goal was to see if the light treatment was practical and eased symptoms.

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Narrow-band UVB phototherapy
- What this could lead to
- If effective, this light treatment could offer a non-drug option to manage painful mouth sores from graft-versus-host disease.
- What could go wrong
- The trial was terminated early and very small (11 people). It is unclear if the light treatment works better than no treatment or has lasting benefits.
