Study Number


Brief Title

COG ALTE1631 – COG ALL Stars

Official Title

A Randomized Web-based Physical Activity Intervention among Children and Adolescents with Acute Lymphoblastic Leukemia

Trial Opening Date

Opened August 14, 2017

General Patient Eligibility

  • Patients diagnosed with acute lymphoblastic leukemia (ALL) and completed treatment within the last 3 months
  • Patients must be between the ages of 8 and 15 years old
  • Patients must have access to a computer or smart phone with Android 4.3 or later or iOS 7.1 or later to use the website
  • At time of consent, patient or parent/guardian report less than 420 minutes (7 hours) of moderate to vigorous physical activity over the last week

General Background and Study Goal

Children and adolescents that have received treatment for ALL are at risk for gaining weight and having lower activity levels, feeling tired, and having problems with their bones, muscles, and overall health. Researchers are investigating whether an interactive website encouraging more physical activity can improve fitness, quality of life, and physical health in children and adolescents who have completed therapy for ALL.

Summary of the Treatment

Patients that decide to participate in this study will:

  • Be given a physical activity monitor called a Sqord, access to a website ( where they can see their own activity and earn rewards
  • Be asked to wear the Sqord device for 6 months and attend 4 clinic visits over 18 months. At each clinic visit, the patient’s weight, height, and waist will be measured. Blood pressure will be checked and the patient will be asked to complete a walking test. Blood will be collected to run special tests.


Risks and Side Effects

All risks and side effects will be explained by your study team during the consent process. They can answer any questions that you may have about giving permission to be in the study. The study consent form has more details about possible risks and side effects of this study.
