What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

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

Completed
The trial has finished. Results may not be published yet.
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)

Summary

This study is recruiting 90 people aged 8-25 who are survivors of childhood leukemia, chronic lung disease of prematurity, or heart transplant, plus healthy controls. Researchers will use non-invasive exercise tests to measure heart and lung function during physical activity. The goal is to better understand why these individuals often have trouble exercising, which could guide future fitness recommendations.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand why some people with chronic childhood diseases struggle with exercise, potentially leading to better fitness programs.
What could go wrong
This is an observational study, not a treatment trial. It will not directly improve health, and results may not apply to everyone with these conditions.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The case participants are the ALL survivors, CLD due to prematurity patients, and post-HT recipients. The control participants can be medical students, UMN staff's children, UMN/Fairview staff, medical residents and undergraduate or graduate students. The remaining controls will be from other UMMCH clinics with conditions unlikely to impact exercise capacity such as dermatology, orthopedics or sports medicine and the University Children's Clinic. Approval will be granted from the treating physician before approaching the control participants

Ages

8 to 25 years

Sex

Anyone
