Fibrosis Lessens After Metabolic Surgery

What this study is testing ClinicalTrials.gov NCT06374875 ↗

Description as written by the study sponsor.

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.

Treatments tested

• Metabolic surgery also known as Bariatric surgery, Roux-en-Y Gastric Bypass (RYGB), Sleeve Gastrectomy (SG) Procedure

  Patients receive either RYGB or SG. The surgical risk, differential impact of each procedure on body weight and other obesity-related diseases, presence of other medical and mental problems, patient's behavioral factors (e.g., postoperative compliance, active smoking), medications, and goals will be considered when the patient and local medical team make a shared decision about the most appropriate surgical procedure

• Incretin-Based Therapy also known as Glucagon-like Peptide-1 Receptor Agonist Drug

  Three incretin-based medications that have been approved for treatment of obesity including liraglutide, semaglutide, or tirzepatide will be used in the nonsurgical group. Any of these 3 medications (in the injection or oral from) based on availability in each country, access, and clinical indications can be used. If possible, patients will be placed on high-dose tirzepatide (Mounjaro or Zepbound 15 mg once weekly injection) or high-dose semaglutide (Wegovy 2.4 mg once weekly injection or Ozempic 2 mg once weekly injection). Other acceptable, less preferrable, options: liraglutide (Saxenda or Victoza), semaglutide tablet (Rybelsus), or lower dose of tirzepatide and semaglutide injections.
