Resmetirom, a THR-β agonist, improves histologic features of MASLD, including resolution of steatohepatitis without worsening fibrosis and improvement in fibrosis stage, in patients with F1-F3 fibrosis.

Resmetirom is the first FDA-approved drug for MASH. In clinical trials, doses of 80mg or 100mg taken daily for 52 weeks significantly improved liver inflammation and fibrosis compared to placebo. It is an option for those with F1-F3 fibrosis.

StrongSupportsHIGH confidence
resmetirom demonstrated superiority at 52 weeks in the primary endpoints of resolution of MASH without worsening of fibrosis (26% and 30% for resmetirom versus 10% in placebo group) and improvement in fibrosis of at least one stage without NAS worsening (24% and 26% for resmetirom versus 14% for placebo).
