Fighting sedentary time in young cancer patients: a digital intervention put to the test
NCT ID NCT07742891
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This trial tests whether a 10-week mobile health program, called ReSeT2, can reduce the time adolescents and young adults with acute lymphoblastic leukemia (ALL) spend sitting during maintenance therapy. Participants aged 13-22 will be randomly assigned to either the intervention—which includes a Fitbit with inactivity prompts, home activity equipment, coaching, and peer support—or usual care. The study measures changes in sedentary time and explores effects on cardiometabolic health and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 10-week mobile health intervention combining a Fitbit with inactivity prompts, home activity equipment, goal-based incentives, coaching, and peer support
- What this could lead to
- If effective, this approach could offer a practical way to reduce sedentary time and improve cardiometabolic health in young leukemia patients during maintenance therapy.
- What could go wrong
- This is a small pilot study, so results may not be conclusive. The intervention's success depends on participant engagement, and it may not lead to lasting changes or generalizable outcomes.
