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.
