Could a Drug Help Treat Fatty Liver Disease in Animal Models?

The study, completed in partnership with an international team including the Laboratory Animal Center at Xi’an Jiaotong University Health Science Center and the Institute of Cardiovascular Sciences at Peking University Health Science Center, is published in

“For years, scientists have been trying to develop a medication that treats NASH, but many attempts have failed to show an improvement or have raised safety concerns in clinical trials,” said Eugene Chen, M.D., Ph.D., senior author of the study and Frederick G. L. Huetwell Professor of Cardiovascular Medicine at University of Michigan Medical School. “NASH is rising at a staggering rate, and successful treatment of non-human primates with our drug candidate, DT-109, brings us closer than ever to treating the millions of people suffering from this condition.”

Potential Drug Treats Fatty Liver Disease in Animal Models: A Closer Look

NASH is the second stage of nonalcoholic fatty liver disease, which is estimated to affect 32% of people worldwide. While fatty liver disease can be treated with exercise and nutritional intervention, the liver damage from NASH is more permanent. It has become the primary cause of chronic liver disease, and NASH-related cirrhosis is now one of the most common reasons for liver transplantation.

While hundreds of compounds have successfully treated NASH in mice, including DT-109, Chen says mouse NASH models are limited because not all aspects of the human disease are accurately mimicked and, therefore, are not easily translatable to the clinic. The research team’s non-human primate model for NASH, confirmed using multiomics profiling studies, is among the first to accomplish the feat.

In both non-human primates and mice, investigators in the international collaboration found that treatment with DT-109 reverses fat buildup and prevents fibrosis progression by stimulating fatty acid degradation and antioxidant formation. The drug also inhibited the production of lithocholic acid, a toxic secondary bile acid closely linked to nonalcoholic fatty liver disease.

“With this significant breakthrough in preclinical models, we can now consider evaluating DT-109 as a potential drug candidate for the treatment of NASH in future clinical trials,” said Jifeng Zhang, Ph.D., co-corresponding author and research associate professor of cardiovascular medicine at Michigan Medicine. “With millions of people suffering from NASH, the need for an effective treatment is more pressing than ever.”
