New drug DD01 shows promise for fatty liver in early trial
NCT ID NCT06410924
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 2 trial tested a drug called DD01 in 67 overweight or obese adults with a type of fatty liver disease (MASLD/MASH). The goal was to see if DD01 could safely reduce liver fat by at least 30% over 48 weeks compared to a placebo. The study is completed, and results will show whether DD01 is a potential treatment for this common liver condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DD01 (a dual GLP-1 and glucagon receptor agonist)
- What this could lead to
- If successful, DD01 could offer a new treatment option to reduce liver fat and improve liver health in people with MASLD/MASH.
- What could go wrong
- This is a small Phase 2 trial with only 67 participants, so results may not apply to everyone. The drug may cause side effects or fail to show clear benefit over placebo.
