Prospects of Late-Stage Development Agents in the Treatment of Metabolic Dysfunction-Associated Steatohepatitis (MASH)

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a spectrum of pathology involving fatty liver disease that may progress to fibrosis, cirrhosis, hepatocellular carcinoma, and liver failure. The prevalence of MASLD and metabolic dysfunction-associated steatohepatitis (MASH) continues to increase, mirroring the rise in global prevalence of related comorbidities such as obesity and type 2 diabetes mellitus. Due to the alarming rise of these comorbidities, a greater proportion of the population is at risk for developing MASLD and MASH. As such, there has been a significant effort to develop effective therapies for MASLD and MASH. Recently, the U.S. Food and Drug Administration approved resmetirom, a selective thyroid hormone receptor-beta agonist, as the first treatment for patients with MASH. In India, the Drug Controller General of India approved saroglitazar, a dual peroxisome proliferator-activated receptor (PPAR) α/γ agonist, for the treatment of MASLD. Currently, we have various drug classes, including liver-specific therapies, in Phase 3 development with even more agents earlier in the pipeline. This review will discuss prospective therapies in later stages of development such as thyroid hormone receptor-beta agonists, PPAR agonists, glucagon-like peptide-1 receptor agonists, fibroblast growth factor 21 agonists, and fatty acid synthase inhibitors.
