Semaglutide Effects in Obese Youth With Prediabetes/New Onset Type 2 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease

April 10, 2026 updated by: Sonia Caprio, Yale University

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 Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

The purpose of this study is to understand the role of GLP-1 in the pathogenesis of T2D in youth and explore their potential salutary effects and ability to delay the progressive loss of ß-cell function and reduce hepatic steatosis in youth with prediabetes/new onset T2D and NAFLD.

Study Overview

Detailed Description

In a recent publication by the TODAY Group Study, it was reported that "diabetes-related complications appear early in youth-onset T2D and accumulate rapidly at a mean age of 26.4 years," and 60.1% of participants developed at least one microvascular complication. The same has been reported in RISE Studies and was suggested that the rapid decline in β-cell function and its insensitivity to two of the most frequently used treatments for T2D in pediatrics is further aggravated by the rising prevalence in NAFLD. These alarming results indicate a pressing need for effective and innovative approaches at preserving β-cell function and reducing hepatic steatosis in obese youth in order to prevent disease progression and associated complications.

This study will provide mechanistic insights in support of a GLP-1 analog, Semaglutide, 2.4 mg weekly, therapy for prediabetes, new onset T2D and NAFLD in youth. The study design is a randomized, double-blind, placebo-controlled, clinical trial (RCT) using Semaglutie (Wegovy up to 2.4mg) for 6 months followed by a wash-out period of 3 months.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Oral Disposition Index (oDI)
Time Frame: Baseline and 6 months
The oDI value is the product of total responsivity index and insulin sensitivity. The change in oDI from baseline to 6M on treatment is calculated as the difference between 6M oDI value and baseline oDI value. The oDI measures the ability of beta-cell to respond to a glucose stimulus.
Baseline and 6 months
Change in Protein Density Fat Fraction (PDFF)
Time Frame: Baseline and 6 months
The change in PDFF from baseline to 6M on treatment is calculated as the difference between 6M PDFF value and Baseline PDFF. It provides an accurate, non-invasive, reproducible, quantitative, and precise estimation of liver fat content. The expected changes in MRI-PDFF from baseline to 6M is ≥ 5.8% reduction compared to the placebo group.
