Early Re-Initiation of Semaglutide Post Sleeve Gastrectomy in Youth

Starting soon · Phase 3

Conditions studied: Pediatric Obesity, Metabolic and Bariatric Surgery, Semaglutide

In brief

This is a Phase 3a, randomized, parallel-controlled trial designed to compare the early re-initiation of semaglutide, starting two weeks after sleeve gastrectomy, to standard care (no pharmacotherapy following surgery). The trial will involve 150 youth with severe obesity who have been on semaglutide 2.4 mg weekly for at least 3 months prior to surgery. Participants will be randomized to either (1) semaglutide 2.4 mg weekly or (2) standard care for 24 months. Primary, secondary, and tertiary outcomes will be assessed at multiple time points: 1-month, day of surgery, and 1-, 3-, 6-, 9-, 12-, 18-, and 24-months postoperatively. We hypothesize that early re-initiation of semaglutide will be safe, well-tolerated, and lead to greater improvements in obesity, cardiometabolic risk, and eating behaviors.

Who can join

Age: 12 and older, up to 18. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• ages 12 to 18 years
• Tanner stage 3 or higher
• severe obesity (defined as a BMI greater than 35 kg/m2 or BMI ≥140% of the 95th percentile)
• currently undergoing primary surgical weight loss through the pediatric bariatric surgery pathway at Children's Hospital Los Angeles
• be willing to have blood collected before and after surgical procedure at defined points
• be willing to have clinical data entered into a prospective database; 8) presence of a consenting caregiver
• be taking semaglutide 2.4 mg weekly as part of their routine medical care prior to surgery as part of their obesity treatment program, apart from any planned surgical procedure.

You may not qualify if…

• have a previous diagnosis of type 1 diabetes
• taking any medications known to influence body composition or prevent weight loss or promote weight gain (e.g. prednisone)
• have been diagnosed with syndromes or diseases that may influence the postoperative course (e.g., Cushing syndrome, Down syndrome, Prader Willi Syndrome)
• have significant comorbid medical conditions necessitating frequent hospitalization that may require interruption of medications and/or that would make early re-initiation of semaglutide unsafe due to the other medical comorbidities
• refuse to comply with eligibility criteria.
