MASH and the race for liver antifibrotics
1Ochre Bio, Oxford, United Kingdom.
New metabolic therapies offer hope for treating liver fibrosis in metabolic dysfunction-associated steatohepatitis (MASH). Emerging treatments target liver fat and fibrosis, potentially improving outcomes for patients with chronic liver disease.
Area of Science:
- Hepatology
- Metabolic Diseases
- Fibrosis Research
Background:
- Metabolic dysfunction-associated steatohepatitis (MASH) and chronic liver diseases cause progressive fibrosis and cirrhosis, a leading cause of death.
- Past antifibrotic drug development has faced challenges, but recent metabolic therapy advances provide new therapeutic avenues.
Purpose of the Study:
- To summarize emerging antifibrotic therapies for MASH and other chronic liver diseases.
- To discuss the potential of metabolic therapies, including direct and indirect-acting agents.
- To explore future therapeutic combinations, patient stratification, and the ultimate goal of fibrosis reversal.
Main Methods:
- Review of current literature on antifibrotic agents, focusing on metabolic therapies.
- Analysis of emerging drug classes, including GLP-1 analogues, THRβ activators, and FGF21 analogues.
- Discussion of non-metabolic antifibrotics and future research directions.
Main Results:
- Metabolic therapies, such as GLP-1 analogues, THRβ activators, and FGF21 analogues, show promise in reducing liver fat and potentially fibrosis.
- Indirect-acting agents promote weight loss to decrease liver fat, while direct-acting agents target specific pathways in the liver.
- Development of non-metabolic antifibrotics is progressing more slowly than metabolic therapies.
Conclusions:
- Emerging metabolic therapies represent a significant advancement in the treatment of liver fibrosis associated with MASH.
- Future strategies may involve combining metabolic and non-metabolic agents, alongside patient stratification, to optimize treatment outcomes.
- The primary therapeutic goal may need to expand beyond just fibrosis reversal to encompass broader patient benefits.
