A study testing whether a GLP-1 medicine from National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), semaglutide, can improve fatty liver disease.

Who can join
Adults 18 to 100, have fatty liver disease (also called MASH or NASH), BMI 25+.
What you take
semaglutide, given as part of the study at no cost to you. Some participants may receive a placebo (an inactive version) instead, decided at random.
How long it lasts
The full study runs about 7.3 years; your own time in it is usually shorter.
What you get
The study medication and study-related care at no cost. Compensation varies by study site; many cover travel and provide the study medication at no cost. The trial coordinator will explain what that site offers before you join.

Key inclusion criteria

  • Male or female Aged >= 18 years of age.
  • Histological evidence of hepatic steatosis on a liver biopsy within 12 months OR evidence of fatty liver disease, as documented by imaging (ultrasound, CT, MRI, MRI-PDFF, MR spectroscopy, or Fibroscan CAP >= 285 db/M25) within 12 months.
  • Estimated average alcohol consumption < 30 g/d for men or < 20 g/d for women in the 6 months prior to enrollment and no binge-drinking behavior.
  • Ability of subject to understand and the willingness to sign a written informed consent document.

Key exclusion criteria

  • Pregnant or breast-feeding
  • Chronic infection with hepatitis C virus (HCV) or hepatitis B virus (HBV). Patients who were treated successfully for HCV and achieved sustained virological response can be eligible for enrollment > 18 months after treatment cessation. Patients receiving antiviral therapy are ineligible.
  • HIV infection.
  • Concomitant liver disease such as autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, Wilson s disease, alpha-1 antitrypsin deficiency, hereditary hemochromatosis.
