Can a weekly shot reverse liver damage from fatty liver disease?
NCT ID NCT07795164
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This Phase 3 trial tests whether pemvidutide, an injected drug, can improve liver health in people with MASH, a condition where fat builds up in the liver and causes inflammation and scarring. The study enrolls about 1,800 adults with moderate liver scarring who do not have cirrhosis. Researchers measure whether the drug leads to resolution of MASH, improves fibrosis, and delays serious liver events like cirrhosis or liver failure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pemvidutide, an investigational drug given by injection
- What this could lead to
- If it works, pemvidutide could become a treatment that reverses liver scarring and lowers the risk of cirrhosis, liver failure, or liver cancer in people with MASH.
- What could go wrong
- This is a large, late-stage trial, but success is not guaranteed. The drug may not outperform placebo, and side effects from the injection could limit its use.
