- Registration Number
- NCT06967389
- Lead Sponsor
- University of Kentucky
- Brief Summary
The goal of this clinical trial is to learn if the drug semaglutide changes markers of disease risk as it relates to weight in children ages 12-15 years old who are obese (class 2 or 3). The main questions it aims to answer are:
* How do the rate of weight loss, body mass index (BMI), body composition, heart structure and function, and exercise ability interact with one another in the study population at enrollment?
* How do risk markers of disease change over the study in the study participants who are given semaglutides to help with weight loss?
* Are there differences in the above factors between males and females and are there key factors to help improve the outcomes?
Participants will be given semaglutide for this study. During the course of the study, participants will:
* have two cardiac MRI scans OR two cardiac echocardiograms (one before starting semaglutide and one around 12 months after taking the drug)
* have body composition and fitness levels assessed twice (before semaglutide and around 12 months after taking it) and have urine specific gravity (USG) measured
* have extra blood drawn when labs their doctor orders are already being drawn (once at the beginning of the study, once around 6 months after enrollment, and once at the end of the study)
* have follow up visits with the study doctor
* be asked to take a pregnancy test if they are female and have started menstruation
- Detailed Description
This is an observational study in which all participants will be given semaglutide. There will be no randomization and no placebo.
Participants will be in the study for 12 months (+/- 2 months) depending on when they reach the maintenance dose of semaglutide.
Blood and urine will be maintained by the principal investigator indefinitely. Identifiers will be removed from the samples.
Approximately 50 patients will be enrolled.
The study drug, Ozempic, is FDA approved.

- Secondary Outcome Measures
Name Time Method Change in Dietary habits Enrollment, 6 months post enrollment, 12 months +/- 2 months post enrollment It assesses the frequency and quality of dietary habits, such as the consumption of fruits, vegetables, whole grains, and unhealthy foods like sugary snacks and fast food.
The scoring is typically based on a scale representing frequency:
0 = Never or less than once per week, 1 = 1-2 times per week, 2 = 3-4 times per week, 3 = 5-6 times per week, 4 = Daily or more.
Higher scores on the healthy scale = better dietary habitsChange in exercise habits Enrollment, 6 months post enrollment, 12 months +/- 2 months post enrollment Assessed with the BMI Clinic dietary and exercise habit survey in which participants record the frequency of activities.
It assesses the frequency, duration, and/or intensity of physical activity (e.g., walking, moderate activity, vigorous activity, including aerobic and strength training).
For interpretation:
High Score: Indicates sufficient physical activity Low Score: Suggests insufficient physical activityPatient Health Questionnaire-9 (PHQ-9) Enrollment, 6 months post enrollment, 12 months +/- 2 months post enrollment The PHQ-9 is a 9-item self-report questionnaire that is widely used to assess depression symptom severity. A PHQ-9 score ≥10 has a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. Higher scores indicating greater depression severity.
Generalized Anxiety Disorder-7 questionnaire (GAD-7) Enrollment, 6 months post enrollment, 12 months +/- 2 months post enrollment A 7 item self-complete questionnaire with very good sensitivity (89%) and specificity (82%) for Generalised Anxiety Disorder (GAD). Response scores for each item ranging from 0 (not at all) to 3 (every day). The range for the total score is 0 to 21, with higher scores representing greater symptoms of anxiety
