App aims to boost breast cancer treatment adherence in real-world study
NCT ID NCT06905301
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether using a mobile app helps people with HR+ HER2- stage II or III breast cancer stick to their prescribed ribociclib and aromatase inhibitor therapy for a full year. The app provides reminders and information about side effects and relapse risks. About 240 participants will be split into two groups—one using the app and one not—to compare how many stay on treatment.
