Experimental drug aims to reverse liver scarring in MASH cirrhosis
NCT ID NCT07704892
First seen Jul 15, 2026 · Last updated Aug 06, 2026 · Updated 3 times
Summary
This Phase 3 trial tests whether efimosfermin alfa can improve liver fibrosis in adults with compensated cirrhosis caused by MASH (a fatty liver disease). Participants receive either the drug or a placebo via injection. The main goal is to see if liver scarring improves by at least one stage without worsening MASH.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an experimental drug called efimosfermin alfa, given as a subcutaneous injection
- What this could lead to
- If successful, this could provide a treatment to improve liver fibrosis and prevent progression to liver failure in people with MASH-related cirrhosis.
- What could go wrong
- This is an early-stage Phase 3 trial with a moderate number of participants; the drug may not show significant benefit over placebo, and side effects are possible.
