The metabolic dysfunction-associated steatohepatitis market has been comprehensively analyzed in IMARC's new report titled "Metabolic Dysfunction-Associated Steatohepatitis Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2026-2036". MASH is a liver condition in which fat levels start accumulating inside the liver, this causes inflammation leading to liver damage. It is caused due to metabolic disorders associated with elevated blood sugar, obesity, and high blood cholesterol. It is a form of fatty liver disease, but it doesn't require extensive alcohol consumption. There may be no immediate signs of MASH at presentation, and then it may be two weeks or longer for the symptoms to start showing up throughout the remaining duration of the illness. Moderate MASH is associated with pain in the right upper quadrant; fatigue; weakness; anorexia; weight loss occurring for no apparent reason. Symptoms can worsen considerably in advanced cases, including easy bruising or bleeding, jaundice due to liver failure, swollen lymph nodes, continuing itching, an enlargement of the liver or spleen, mental confusion, drowsiness, and slurred speech. Diagnosing MASH involves clinical assessments, family history, blood tests, and liver stiffness measurements. Imaging techniques like abdominal ultrasounds and CT scans are used by doctors to confirm the presence of fat in the liver.

The rising rate of metabolic syndrome, a condition characterized by obesity, hypertension, and high cholesterol that leads to fat deposition in the liver, inflammation, and scarring is driving the market for metabolic dysfunction-associated steatohepatitis. The other support factor for the market growth is the action of THR-beta agonists, such as resmetirom, that can reverse the course of the disease by regulating lipid metabolism in the liver. The increasing use of dietary supplements such as vitamin E, omega-3 fatty acids, and silymarin, said to help ameliorate disease symptoms and improve liver health, further drives market growth. Moreover, the increased acceptance of bypass surgery for the severely obese is another key driver. It has a profound effect on gut hormones, such as glucagon-like peptide-1, that improve insulin sensitivity and inhibit liver inflammation. Also, increasing awareness of stem cell therapy is going to give momentum to the entire metabolic dysfunction-associated steatohepatitis market in the forecast period, together with a probability of regenerating liver tissue, lessening fibrosis, and improving liver function.

Recent Developments:

• In September 2025, Roche announced the acquisition of 89bio in a deal valued at up to US$ 3.5 Billion, aiming to strengthen its presence in metabolic dysfunction-associated steatohepatitis (MASH) through 89bio’s late-stage candidate Pegozafermin, which is expected to deliver best-in-disease efficacy and compete in the rapidly growing MASH treatment landscape.
• In August 2025, Novo Nordisk received accelerated approval from the U.S. Food and Drug Administration for Wegovy to treat patients with metabolic dysfunction-associated steatohepatitis (MASH) and moderate-to-advanced liver fibrosis, based on Phase III data demonstrating improvements in liver scarring and disease resolution.
• In January 2025, Akero Therapeutics, Inc. publicly disclosed the topline early results week 96 of SYMMETRY, a Phase 2b clinical trial evaluating the safety and effectiveness of efruxifermin (EFX), its lead product candidate, in patients diagnosed with Child-Pugh Class A, or compensated cirrhosis (F4), which is attributed to metabolic dysfunction-associated steatohepatitis (MASH). Among patients with baseline and week 96 biopsies (n=134), 39% of those treated with 50mg EFX (n=46) (p=0.009) showed cirrhosis reversal with no worsening of MASH, compared to 15% who received placebo (n=47).

Drugs:

Rezdiffra is administered to the patient with metabolic dysfunction-associated steatohepatitis and with moderate to severe liver fibrosis, in conjunction with diet and exercise. Rezdiffra works as a partial agonist of the thyroid hormone receptor beta, which is predominantly expressed by the cells in the liver, and regulates the genes that function in lipid metabolism. This therefore results in decreasing intrahepatic triglycerides and enhances liver health due to the reduced liver fat.

Pegozafermin, developed by 89bio, acts by mimicking the naturally occurring protein fibroblast growth factor 21 (FGF21) which predominantly targets the liver. The medicine has anti-inflammatory and anti-fibrotic properties that reduce liver fat accumulation, enhance insulin sensitivity, and lower triglyceride levels, assisting in the treatment of metabolic dysfunction-associated steatohepatitis by targeting key drivers of hepatic fibrosis and inflammation. Its mechanism includes processes such as enhanced adiponectin synthesis and enhanced free fatty acid management in the liver.

Efruxifermin, developed by Akero Therapeutics, mimics the natural activity of the metabolic hormone fibroblast growth factor 21 (FGF21), binding to its receptors in the cells of the liver and adipose tissue to alter metabolic pathways, thus reducing hepatic fat accumulation, inflammation, and fibrosis, all of which are hallmarks of MASH. Essentially, it functions as an FGF21 agonist, increasing insulin sensitivity and lipid profiles while addressing many elements of MASH disease progression via a whole-body approach.

Miricorilant is a drug developed by Corcept Therapeutics, which acts as a selective glucocorticoid receptor modulator (SGRM) and mineralocorticoid receptor antagonist. It mainly works through interaction with these receptors in the liver, thereby reducing the buildup of hepatic fat and probably improving metabolic indicators, thus becoming a potential therapy for metabolic dysfunction-associated steatohepatitis.

ALG-055009 is the best-in-class thyroid hormone receptor beta agonist intended for use in the management of metabolic dysfunction-associated steatohepatitis. It achieves its effect through the inhibition of APOC3, the protein that influences lipid metabolism. The inhibition of APOC3 by ALG-055009 restores the normal lipid metabolism and reduces liver fat accumulation to enhance insulin sensitivity, thereby minimizing inflammation and fibrosis.
