Efruxifermin is an Fc-FGF21 fusion protein (human IgG1 Fc domain linked to a modified human FGF21). Efruxifermin has prolonged half-life and enhanced receptor affinity compared with native human FGF21. Efruxifermin can be used for the research of non-alcoholic steatohepatitis.
Efruxifermin (0-100 mg/kg, SC, Once weekly, for 4 or 26 weeks) reduces body weight gain of Sprague Dawley rats in a dose-dependent manner[1].
