New shot shows promise against fatty liver disease
NCT ID NCT05989711
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a weekly injection called pemvidutide in 212 adults with NASH, a serious liver condition linked to fat buildup. The goal was to see if the drug could reduce liver fat and scarring without worsening the disease. Participants received either the drug or a placebo for 24 weeks, and researchers measured changes in liver health through biopsies and scans.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pemvidutide (a weekly injection)
- What this could lead to
- If successful, this could provide a new treatment to reduce liver fat and scarring in people with NASH, potentially preventing progression to cirrhosis.
- What could go wrong
- This is an early Phase 2 trial with only 212 participants. The drug may not work better than placebo, and side effects are possible. Results need confirmation in larger studies.
