At the interim analysis, semaglutide achieved both primary endpoints. Resolution of steatohepatitis without fibrosis worsening occurred in 62.9% of patients receiving semaglutide compared with 34.3% in the placebo group (difference, 28.7%; 95% CI, 21.1–36.2; P <.001). Reduction in fibrosis without worsening steatohepatitis was observed in 36.8% of the semaglutide group versus 22.4% with placebo (difference, 14.4%; 95% CI, 7.5–21.3; P <.001).
Secondary outcomes showed combined resolution of steatohepatitis and fibrosis reduction in 32.7% of semaglutide-treated patients versus 16.1% with placebo (difference, 16.5 percentage points; P <.001). Patients on semaglutide also experienced a mean body weight reduction of 10.5% versus 2.0% in the placebo group (difference: −8.5%; P <.001).
While semaglutide was linked to a slight improvement in bodily pain scores on the SF-36, the result did not reach prespecified statistical significance. Adverse events occurred in 86.3% of the semaglutide group and 79.7% of the placebo group, primarily gastrointestinal. Rates of serious adverse events were similar at 13.4% in both groups.
Resmetirom (Rezdiffra) is the only US Food and Drug Administration (FDA)-approved treatment for noncirrhotic MASH. These findings position semaglutide as a potential future option, pending results from the full ESSENCE trial and regulatory review.
