Study 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
Read the 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.

Study population

Participants will be recruited from the University of Kentucky's High BMI and/or Pediatric Nephrology Clinics.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient seen at University of Kentucky Pediatric High Clinic
  • Diagnosis of Obesity Class 2 or 3
  • Meeting the clinical criteria for the medical intervention with semaglutide for weight loss

Exclusion criteria

Exclusion Criteria:

  • Any current prescribed anti-obesity medications (AOM) such as Orlistat, Phentermine, Qsymia (Phentermine/Topiramate), Liraglutide, Semaglutide, and Setmelanotide
  • Any current prescribed anti-hypertensive medications
  • Any specific end-organ acute concerns (kidney disease, liver disease, congenital disease).
  • Any active infections at enrollment.
  • Any systemic use longer than 3 month use or within the last month before enrollment (not including inhaled, ophthalmic, intranasal, and topical).
  • Any limitations that would make exercise testing not possible.
  • Any congenital abnormality or genetic syndrome known to be associated with obesity
  • Pregnancy
  • Inability to receive an MRI
  • Personal or family history of medullary thyroid carcinoma (per product insert)
  • Patients with Multiple Endocrine Neoplasia syndrome type 2 (per product insert)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Secondary outcomes

  1. Change in Dietary habits

    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 habits

    Time frame: Enrollment, 6 months post enrollment, 12 months +/- 2 months post enrollment

  2. Change in exercise habits

    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 activity

  3. Patient Health Questionnaire-9 (PHQ-9)

    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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2025 (actual). Primary completion is estimated for Jul 2027, 25 months after the start.

Of 791 non-industry observational studies under Obesity, half reached primary completion within 40 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 106. This study's planned 25 months is below that.

Counting every sponsor, half of 836 studies reached it within 39 months; a quarter within 17 and three quarters within 96.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
