The trial achieved both its primary endpoints, with semaglutide 2.4 mg demonstrating statistically significant and superior improvements in liver fibrosis with no worsening of steatohepatitis, as well as resolution of steatohepatitis with no worsening of liver fibrosis in people with MASH compared to placebo.¹
Supportive secondary endpoints showed improvements in liver enzymes, including alanine transaminase (ALT), aspartate transaminase (AST), and gamma-glutamyl transferase (GGT), as well as the Enhanced Liver Fibrosis (ELF)^TM test.¹
One in 20 adults in the US are living with metabolic dysfunction-associated steatohepatitis (MASH)², with MASH progressing to cirrhosis in 20% of all cases.³

PLAINSBORO, N.J., Nov. 19, 2024 /PRNewswire/ -- Novo Nordisk today announced results from part 1 of the ongoing Phase 3 ESSENCE trial. Part 1 evaluated the effect of once-weekly subcutaneous semaglutide 2.4 mg on liver tissue (histology) compared with placebo in people with metabolic dysfunction-associated steatohepatitis (MASH) and moderate to advanced liver fibrosis (stage 2 or 3).⁴ Results were presented at the 75^th American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting^®.

At Week 72, primary endpoints showed 62.9% of people treated with semaglutide 2.4 mg achieved resolution of steatohepatitis with no worsening of liver fibrosis compared to 34.1% on placebo. 37.0% of people treated with semaglutide 2.4 mg achieved improvements in liver fibrosis with no worsening of steatohepatitis compared to 22.5% on placebo. Overall, secondary endpoints showed 32.8% of patients treated with semaglutide 2.4 mg achieved both resolution of steatohepatitis with improvements in liver fibrosis (as compared to 16.2% of patients on placebo).¹

“These initial data shared at The Liver Meeting^® demonstrated that semaglutide 2.4 mg slowed MASH progression and reversed existing liver damage,” said Arun Sanyal, MD, principal investigator of the study, and Director, Stravitz-Sanyal Institute for Liver Disease and Metabolic Health, Virginia Commonwealth University. “The ESSENCE data may represent key findings for patients in the treatment of MASH, which is estimated to affect about one in 20 adults in the US.”

In addition to meeting both primary endpoints, secondary endpoints showed histological benefits were reflected in improvements of pre-specified non-invasive tests (NITs) in people treated with semaglutide 2.4 mg vs placebo. The additional data showed improvements in liver enzymes (including ALT, AST, and GGT), as well as the Enhanced Liver Fibrosis (ELF)™ test. In the trial, semaglutide 2.4 mg appeared to have a safety profile similar to previous semaglutide 2.4 mg trials in other therapeutic area patient populations.¹

“We are pleased by the ESSENCE data presented at AASLD, which supports the growing clinical evidence of semaglutide 2.4 mg for people living with chronic conditions like MASH,” said Anna Windle, PhD, senior vice president of Clinical Development, Medical & Regulatory Affairs at Novo Nordisk. “These data are a cornerstone in our research and build on our understanding of how MASH and cardiometabolic conditions like type 2 diabetes, obesity, dyslipidemia, and high blood pressure are interrelated.”

Semaglutide 2.4 mg is not approved in the US to treat MASH. Novo Nordisk expects to file for regulatory approvals in the US in the first half of 2025.

About ESSENCE (semaglutide 2.4 mg)
ESSENCE is a Phase 3 trial evaluating the effect of once-weekly subcutaneous semaglutide 2.4 mg in adults with metabolic dysfunction-associated steatohepatitis with moderate to advanced liver fibrosis (stage 2 or 3). It is a two-part trial where 1,200 planned participants were randomized 2:1 to receive semaglutide 2.4 mg or placebo, on top of standard of care for 240 weeks. In part 1, the objective was to demonstrate that treatment with semaglutide 2.4 mg improves liver histology at 72 weeks based on biopsy sampling from the first 800 randomized patients. In part 2, the objective is to demonstrate that treatment with semaglutide 2.4 mg lowers the risk of liver-related clinical events compared to placebo in adults with MASH and moderate to advanced liver fibrosis at 240 weeks.⁴ About metabolic dysfunction-associated steatohepatitis (MASH)
MASH is a chronic, progressive, metabolic disease affecting the liver, which can be potentially life-threatening if not properly managed.^5,6 Among people who are overweight or obese, more than one in three also have MASH.⁷Excess fat can build up in the liver, which over time, can lead to inflammation and severe scarring of the liver.⁸ People living with MASH often experience few or no specific symptoms in the early stages of the disease, which often results in delayed diagnosis.⁹ One in 20 adults in the United States are living with MASH.² The disease progresses to cirrhosis in approximately 20% of cases.³ MASH is a leading cause of cirrhosis in adults in the US, and MASH-related cirrhosis is the second indication for liver transplants in the country.¹⁰
