Adjuvant Endocrine Therapy Adherence Intervention Pilot in Rwanda

This is a randomized study evaluating a light-touch, multi-modal medication adherence support package designed to improve adherence to adjuvant endocrine therapy in adults with confirmed ER-positive breast cancer undergoing curative intent treatment. Eligible participants will be within 6-36 months of adjuvant endocrine therapy initiation and will be randomized to receive either standard care or the medication adherence support package, which includes a one-time educational video, a symptom monitoring card, and weekly one-way text message reminders. The research study procedures include: screening for eligibility, questionnaires/surveys, interviews, educational video, symptom monitoring card, and weekly text message reminders (as applicable). No additional in-person or telephone contact with research staff is planned beyond delivery of these materials. It is expected that about 224 adults will take part in this study across all sites. Participation in this research study is expected to last about 6 months.
