Madrigal to Present Late-Breaking Resmetirom Data in Patients with Compensated MASH Cirrhosis at the EASL Congress

Rhea-AI Summary

Madrigal Pharmaceuticals announced six presentations at the upcoming EASL Congress in Amsterdam (May 7-10, 2025), featuring crucial data about their drug resmetirom for MASH treatment. The highlight is a late-breaking presentation on two-year data from patients with compensated MASH cirrhosis.

Resmetirom, the first FDA-approved medication for MASH in the US, is a daily oral liver-directed THR-β agonist. The drug showed promising results in the Phase 3 MAESTRO-NASH trial, with 91% of patients on 100mg dosage experiencing liver stiffness improvement or stabilization.

Currently under review by European regulators, Madrigal expects a CHMP opinion and EU decision by mid-2025, with potential launches starting in Germany in late 2025. The company will host an investor webcast on May 13, 2025, to review detailed two-year data from the compensated MASH cirrhosis study.

CONSHOHOCKEN, Pa., April 29, 2025 (GLOBE NEWSWIRE) -- Madrigal Pharmaceuticals, Inc. (NASDAQ: MDGL), a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), today announced six presentations at the upcoming European Association for the Study of the Liver (EASL) Congress, taking place from May 7-10, 2025, in Amsterdam, the Netherlands. Madrigal will share detailed two-year data from the open-label compensated MASH cirrhosis (F4c) arm of the Phase 3 MAESTRO-NAFLD-1 trial in a late-breaking oral presentation titled, “Treatment with resmetirom for up to two years led to improvement in liver stiffness, fibrosis biomarkers, fibrosis scores and portal hypertension risk in 122 patients with compensated MASH cirrhosis.”

“Patients with compensated MASH cirrhosis who develop clinically significant portal hypertension are at greatly elevated risk of experiencing life-threatening complications of late-stage liver disease so there is an urgent need to advance new treatment strategies for this vulnerable population,” said Bill Sibold, Chief Executive Officer of Madrigal. “The late-breaking data we will be presenting at EASL suggest that resmetirom may help halt or reverse disease progression in patients with compensated MASH cirrhosis, and we look forward to sharing important new findings examining the medication’s impact on portal hypertension risk. These data reinforce our conviction in resmetirom’s potential to become the foundational therapy across F2 to F4c MASH.”

“This EASL Congress comes at an ideal time for our growing team in Europe,” added Neil Archer, Executive Vice President and Head of International for Madrigal. “As we prepare for a European Commission decision on our marketing authorization application for resmetirom, EASL will provide a valuable opportunity to listen, learn and engage with healthcare providers, patient advocates and other stakeholders who are working to improve care for this serious disease.”

Resmetirom is a once-daily, oral, liver-directed thyroid hormone receptor (THR)-β agonist designed to target key underlying causes of MASH. It is the first approved medication for the treatment of MASH in the U.S. In the pivotal Phase 3 MAESTRO-NASH biopsy trial, resmetirom achieved both fibrosis improvement and MASH resolution primary endpoints, and 91% of patients treated with resmetirom 100 mg experienced improvement or stabilization of liver stiffness. In the U.S., resmetirom is indicated in conjunction with diet and exercise for the treatment of adults with noncirrhotic MASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Continued approval for this indication may be contingent upon verification and description of clinical benefit in ongoing confirmatory trials.

Resmetirom is not approved in Europe for the treatment of patients with MASH with moderate to advanced liver fibrosis and not approved in any geography for the treatment of patients with cirrhosis. A marketing authorization application (MAA) for resmetirom is under evaluation with the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP). The CHMP opinion and subsequent European Union (EU) decision are expected in mid-2025. Madrigal expects to launch resmetirom in Europe on a country-by-country basis commencing with Germany in the second half of 2025, pending European Commission approval.

About MASH
Metabolic dysfunction-associated steatohepatitis (MASH), formerly known as nonalcoholic steatohepatitis (NASH), is a serious liver disease that can progress to cirrhosis, liver failure, liver cancer, need for liver transplantation, and premature mortality. MASH is expected to become the leading cause of liver transplantation in the U.S. and is already the leading cause of liver transplantation among women.

Once patients progress to MASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis), the risk of adverse liver outcomes increases dramatically: these patients have a 10-17 times higher risk of liver-related mortality as compared to patients without fibrosis. Those who progress to cirrhosis face a 42 times higher risk of liver-related mortality, underscoring the need to treat MASH before complications of cirrhosis develop. MASH is also an independent driver of cardiovascular disease, the leading cause of mortality for patients.

An estimated 1.5 million patients have been diagnosed with MASH in the U.S., and Madrigal is focused on reaching approximately 315,000 patients with moderate to advanced fibrosis who are under the care of liver specialists. As MASH disease awareness improves and disease prevalence increases, the number of diagnosed patients with MASH with moderate to advanced fibrosis is expected to grow.

About Rezdiffra
What is Rezdiffra?
Rezdiffra is a prescribed medicine used along with diet and exercise to treat adults with nonalcoholic steatohepatitis (NASH) with moderate to advanced liver scarring (fibrosis), but not with cirrhosis of the liver.

It is not known if Rezdiffra is safe and effective in children (under 18 years old).
This indication is approved based on improvement of NASH and liver scarring (fibrosis). There are ongoing studies to confirm the clinical benefit of Rezdiffra.

Before you take Rezdiffra, tell your healthcare provider about all of your medical conditions, including if you:

• have any liver problems other than NASH.
• have gallbladder problems or have been told you have gallbladder problems, including gallstones.
• are pregnant or plan to become pregnant. It is not known if Rezdiffra will harm your unborn baby.
• are breastfeeding or plan to breastfeed. It is not known if Rezdiffra passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take Rezdiffra.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

• Rezdiffra and other medicines may affect each other, causing side effects. Rezdiffra may affect the way other medicines work, and other medicines may affect how Rezdiffra works.
• Especially tell your healthcare provider if you take medicines that contain gemfibrozil to help lower your triglycerides, or cyclosporine to suppress your immune system, because Rezdiffra is not recommended in patients taking these medicines.
• Tell your healthcare provider if you are taking medicines such as clopidogrel to thin your blood or statin medicines to help lower your cholesterol.
• Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.
