Effects of Semaglutide on Obese Youth with Prediabetes and Liver Disease

Semaglutide, 2.4mg, Once Weekly: Effects on Beta-cell Preservation and Reduction of Intrahepatic Triglyceride Content in Obese Youth With Prediabetes (IGT)/Early Type 2 Diabetes (T2D) and Non-Alcoholic Fatty Liver Disease (NAFLD)

Phase 2 Interventional Yale University · NCT05067621

This study is testing if Semaglutide can help overweight young people aged 10 to 21 with prediabetes and liver disease by improving their blood sugar levels and reducing fat in their liver.

What this trial studies

This clinical trial investigates the effects of Semaglutide, a GLP-1 analog, on obese youth aged 10 to 21 years who have prediabetes, new onset Type 2 Diabetes, and Non-Alcoholic Fatty Liver Disease (NAFLD). The study is designed as a randomized, double-blind, placebo-controlled trial, where participants will receive Semaglutide or a placebo for six months, followed by a three-month wash-out period. The goal is to understand how Semaglutide can help preserve beta-cell function and reduce liver fat in this population, addressing a critical need for effective treatments in youth-onset diabetes.

Who should consider this trial

Good fit: Ideal candidates are obese youth aged 10 to 21 years with prediabetes or new onset Type 2 Diabetes and NAFLD.

Not a fit: Patients with severe comorbidities or those not meeting the eligibility criteria, such as those outside the specified age range or with uncontrolled health issues, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve metabolic health and prevent complications in obese youth with prediabetes and Type 2 Diabetes.

How similar studies have performed: Previous studies have shown promising results with GLP-1 analogs in managing Type 2 Diabetes, suggesting potential success for this approach in youth.
