What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
