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.
