Summary

This phase 2b trial tests whether efruxifermin, an experimental drug, can improve liver fibrosis (scarring) without worsening inflammation in people with compensated cirrhosis due to NASH. Participants receive either efruxifermin or a placebo for up to 96 weeks. The main goal is to see if more people on the drug achieve at least a one-stage reduction in fibrosis compared to placebo.

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 efruxifermin
What this could lead to
If successful, this could point toward a treatment that reverses liver scarring in people with advanced NASH cirrhosis, potentially preventing the need for a liver transplant.
What could go wrong
This is an early-phase trial with a modest number of participants, so results may not confirm benefit. The drug may cause side effects or fail to improve fibrosis in a larger population.
