Efruxifermin in Compensated Liver Cirrhosis Caused by MASH

In phase 2 trials involving patients with stage 2 or 3 fibrosis caused by metabolic dysfunction-associated steatohepatitis (MASH), efruxifermin, a bivalent fibroblast growth factor 21 (FGF21) analogue, reduced fibrosis and resolved MASH. Data are needed on the efficacy and safety of efruxifermin in patients with compensated cirrhosis (stage 4 fibrosis) caused by MASH.

In this phase 2b, randomized, placebo-controlled, double-blind trial, we assigned patients with MASH who had biopsy-confirmed compensated cirrhosis (stage 4 fibrosis) to receive subcutaneous efruxifermin (at a dose of 28 mg or 50 mg once weekly) or placebo. The primary outcome was a reduction of at least one stage of fibrosis without worsening of MASH at week 36. Secondary outcomes included the same criterion at week 96.
