First seen Feb 06, 2026 · Last updated Apr 28, 2026 · Updated 11 times

Summary

This study tests whether shining a special light (photobiomodulation) inside the mouth can safely ease painful sores from chronic graft-versus-host disease, a common complication after a stem cell transplant. About 44 people aged 4 and older who have mouth sores that didn't improve with standard treatments will receive either the light therapy or a fake treatment. The main goal is to see if the sores get better after 28 days.
