Official title: Comparative effectiveness of pharmacotherapies and bariatric surgery for metabolic dysfunction associated steateohepatitis

Funded at Seattle Inst for Biomedical/clinical Res · NIH-11448529 · Data updated 2026-11-12

This program looks at how two drugs and bariatric surgery work for adults with metabolic dysfunction–associated steatohepatitis (MASH) and liver fibrosis.

Who could benefit from this research

Could help

Adults with MASH and stage 2-3 fibrosis who might be candidates for GLP-1/GIP therapies or bariatric surgery.

Less likely to help

If you do not have MASH or have no fibrosis progression risk, the study findings may be less relevant to you.

What this research studies

If you have MASH, this project plans to use high-quality observational data from national health records to compare how semaglutide, tirzepatide, and bariatric surgery affect liver-related outcomes. The team will emulate randomized trial design in real-world data to estimate which approach most reduces serious liver events. The goal is to provide clear evidence on treatments that could lower risk of cirrhosis, liver failure, and liver cancer for patients like you.

Why it matters

Potential benefit: If successful, this work could guide doctors on which treatment approach best lowers serious liver outcomes for adults with MASH.

How similar studies have gone: Previous trials showed fibrosis reduction with some drugs, but high-quality evidence on major liver outcomes is still needed, making this study novel in its real-world approach.
