Editor's note
A large, well-controlled phase 2 RCT in which semaglutide is a core study arm, not an incidental mention. The combination with zalfermin failed to beat placebo on the fibrosis endpoint, but semaglutide 2.4 mg alone was associated with a nominally significant improvement, prompting the authors to flag it for further study in the F4c cirrhosis population. Gastrointestinal adverse events were common, consistent with the known profile.
Plain-language abstract
In this phase 2 randomised trial in people with steatohepatitis and significant liver fibrosis, adding zalfermin to semaglutide did not improve fibrosis over placebo, while semaglutide alone showed a nominally significant improvement.
