Study Overview

Metabolic dysfunction-associated steatotic liver disease (MASLD) (previously NAFLD) affects approximately 25-30% of the global population and is projected to become the leading cause of liver transplantation in the United States by 2030. Development of efficient screening strategies for the identification and treatment of individuals who are at greatest risk for advanced disease in this population is an urgent and unmet medical need.

Type 2 diabetes mellitus (T2DM) and obesity are critical risk factors for advanced MASLD. In a prospective cross-sectional study of patients with type 2 diabetes, we screened 524 participants (50-80 years old) with type 2 diabetes mellitus for the presence of MASLD and observed relative prevalences of 70% for steatosis and 15% for advanced fibrosis. The presence of obesity in this population further increased the odds of advanced fibrosis. These findings suggest that screening populations of individuals with obesity or T2DM may be an effective strategy for identifying high-risk patients with MASLD.

Semaglutide is a glucagon-like peptide 1 receptor agonist (GLP-1 RA) that is FDA-approved for the treatment of obesity (as Wegovy) or T2DM (as Ozempic), conditions that are considered major risk factors for advanced fibrosis in the MASLD population. It is unclear, however, whether semaglutide is effective for treatment of fibrosis due to MASLD in these populations. Here, we propose to conduct a community intervention study that will:

  1. Validate a screening approach to identify patients at risk for advanced MASLD in the obese or T2DM population and,
  2. Test whether semaglutide treatment is effective for the management of significant fibrosis due to MASLD in high-risk patients.
