Do GLP-1s help fatty liver disease?

FDA has approved Wegovy for this, in the words of each label below. ESSENCE (Semaglutide): A planned interim result at 72 weeks from the first 800 of 1,197 people, in a trial still running. Steatohepatitis resolved without worse fibrosis in 62.9% on semaglutide against 34.3% on placebo. Fibrosis improved without worse steatohepatitis in 36.8% against 22.4%.

What each label says on fatty liver disease

The approved use, word for word from each current label.

  • Wegovy: for the treatment of noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (NASH), with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis) in adults. This indication is approved under accelerated approval based on improvement of MASH and fibrosis. Continued approval for this indication may be contingent upon the verification and description of clinical benefit in a confirmatory trial.

The registry

Trials on fatty liver disease, by medicine

A trial counts when the registry's conditions or title name this, and some study a related question, such as insulin sensitivity in people with the condition. A registered trial shows a question being asked, not that the answer is yes.

Questions

GLP-1s and fatty liver disease: common questions

What did the largest trial on fatty liver disease find?

ESSENCE (Semaglutide, 800 people): A planned interim result at 72 weeks from the first 800 of 1,197 people, in a trial still running. Steatohepatitis resolved without worse fibrosis in 62.9% on semaglutide against 34.3% on placebo. Fibrosis improved without worse steatohepatitis in 36.8% against 22.4%.

Is any GLP-1 FDA approved for fatty liver disease?

Yes: Wegovy. Wegovy's label: for the treatment of noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (NASH), with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis) in adults. This indication is approved under accelerated approval based on improvement of MASH and fibrosis. Continued approval for this indication may be contingent upon the verification and description of clinical benefit in a confirmatory trial.

Does insurance cover a GLP-1 for fatty liver disease?

Plans decide, and they usually tie coverage to a medicine's approved uses, so Wegovy is the place to start. Ask your plan whether it covers the medicine for this diagnosis and whether it needs prior authorization.

Which GLP-1 has been studied most for fatty liver disease?

Semaglutide, with 33 registered trials on it, then Liraglutide with 11. More trials do not mean better results: read what each posted.

Can I join a trial of a GLP-1 for fatty liver disease?

9 trials are recruiting on ClinicalTrials.gov now, listed below with their registry pages, which name each site and who can enroll.
