Pemvidutide for noncirrhotic MASH: a phase 3 study
Official title: A Phase 3, Multinational, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy, Safety, and Clinical Outcomes of Pemvidutide in Subjects With Noncirrhotic Metabolic Dysfunction-Associated Steatohepatitis (MASH)
Run by Altimmune, Inc. · NCT07795164 · Data updated 2026-11-12
This phase 3 study tests pemvidutide versus placebo in adults with noncirrhotic MASH to see if it improves liver health and safety.

Is this trial a fit for you?
✓Likely a good fit
Adults with BMI ≥25 kg/m2 (≥23 for Asian), diabetes or metabolic syndrome components, and histologic F2/F3 MASH or noninvasive F2/F3 MASH per cohort criteria.
✕Probably not a fit
Patients with cirrhosis (F4), uncontrolled diabetes, significant liver disease other than MASH, or abnormal liver tests may not benefit.

What this trial studies
This is a multicenter, multinational, randomized, double-blind, placebo-controlled phase 3 trial in adults with noncirrhotic MASH (F2/F3). Participants are assigned to Cohort 1 based on histology or Cohort 2 based on noninvasive tests, and will receive pemvidutide or placebo for a specified period. The study focuses on efficacy, safety, and clinical outcomes, with inclusion requirements including BMI ≥25 and diabetes or metabolic syndrome components. Key exclusions include cirrhosis, portal hypertension, active liver disease other than MASH, and uncontrolled diabetes. Liver biopsy may be required for Cohort 1 per protocol.
Why it matters
Potential benefit: If successful, pemvidutide could improve liver health and metabolic outcomes for people with noncirrhotic MASH.
How similar studies have gone: Previous trials in related metabolic and liver disease areas have shown signal with similar therapies, but this exact approach in noncirrhotic MASH is being evaluated.
