NCT ID NCT05690971
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study tests a mobile app called Horizons designed to help people with chronic graft-versus-host disease (GVHD) after a stem cell transplant. The app aims to improve quality of life, reduce symptoms, and support coping. About 120 adults with moderate to severe chronic GVHD will use the app or receive usual care, and their well-being will be compared after 8 weeks.
