DT-109 Reverses Severe MASH in Animals by Repairing Gut Barrier, Targeting Disease Affecting 7%

Summary
Animal studies showed DT-109 reversed severe MASH by restoring the intestinal barrier and cutting the flow of harmful microbial products to the liver.
Researchers traced the effect to lower Clostridium perfringens levels and reduced gut ammonia, which otherwise damages the gut lining and triggers liver inflammation, including excess CD8+ T-cell activity.
Mice and nonhuman primates both improved, with the primate results standing out because their liver biology and gut microbiota more closely resemble humans.
About 7% of people worldwide have MASH, a fatty liver disease that can progress to cirrhosis, liver cancer and liver failure, while effective treatments remain limited.
The University of Michigan team said more testing is needed before clinical trials; DT-109 is patented and licensed to Diapin Therapeutics, which is continuing development.
A new liver drug repairs the gut. Could it also treat heart disease and digestive disorders?
As weight-loss drugs enter the MASH market, can this new gut-focused pill offer a more direct cure?
DT-109 Shows Preclinical Success in Reversing MASH by Targeting Gut Microbiome: Human Trials on the Horizon
Overview
Metabolic Dysfunction-Associated Steatohepatitis (MASH) is a major health challenge, and as of July 2026, effective treatments are still needed. Recent preclinical research highlights DT-109, an experimental drug that shows strong potential in reversing MASH in animal models. DT-109 works by protecting the gut epithelial barrier, which helps reduce the entry of harmful microbial products into the body—factors known to drive MASH progression. This gut-focused approach not only benefits the gastrointestinal system but also represents a promising step forward in the search for therapies that can truly reverse MASH.
