The primary endpoint focuses on the within-patient change in physical activity between Week 1 and Week 5, with comparison between treatment groups to assess potential differences attributable to the intervention.\n\nSecondary objectives include the exploratory assessment of patient satisfaction with the reminder app, its impact on the use and perception of digital health technology.\n\nA total of 28 evaluable patients in the Full Analysis Set (approximately 14 per treatment arm) are required to detect a clinically relevant difference corresponding to a probability of superiority of approximately 0.65 with 80% power at a two-sided significance level of 0.05.
