- Secondary analysis from the Phase 3 MAESTRO-NASH and MAESTRO-NAFLD-1 trials examines improvements in lipid profiles for Lp(a), LDL-C and ApoB with Rezdiffra® (resmetirom)
- Analysis of two-year data in patients with compensated MASH cirrhosis (F4c) examines improvement in ANTICIPATE-NASH risk scores, a marker for clinically significant portal hypertension
- Additional abstracts focus on early real-world evidence with Rezdiffra and the ability of noninvasive biomarkers to predict fibrosis improvement in patients treated with Rezdiffra
CONSHOHOCKEN, Pa., May 20, 2026 (GLOBE NEWSWIRE) -- Madrigal Pharmaceuticals, Inc. (NASDAQ: MDGL), a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), today announced that multiple abstracts from its Rezdiffra development and real-world evidence programs will be presented at the European Association for the Study of the Liver (EASL) Congress 2026, taking place May 27–30 in Barcelona, Spain.
The presentations highlight the breadth of evidence supporting Rezdiffra, including a secondary analysis on cardiometabolic risk in patients with MASH, non-invasive risk stratification in patients with compensated cirrhosis and early real-world evidence from routine clinical practice.
“The body of data presented at EASL 2026 reinforces Madrigal’s leadership in MASH and clearly supports the continued integration of Rezdiffra into clinical practice as a foundational therapy,” said David Soergel, M.D., Chief Medical Officer of Madrigal. “These analyses extend beyond liver-focused assessments to explore Rezdiffra’s effects on markers of cardiovascular risk and provide important new insights about noninvasive measures of treatment response in patients with moderate to advanced fibrosis (F2-F3) and well-compensated MASH cirrhosis (F4c).”
Madrigal Poster Presentations at the EASL Congress 2026:
| Title | Presenter |
| Reducing CV risk in patients with MASH independent of baseline based on Lp(a) and LDL lowering by resmetirom | Meena Bansal |
| Baseline ANTICIPATE score and response predicts liver outcome events in a 180 patient MASH cirrhosis cohort treated with resmetirom | Naim Alkhouri |

| Early and Week 52 biomarker (MRI-PDFF, ALT, MRE and PRO-C3) responses to resmetirom predict improvements in MASH and liver fibrosis | Rohit Loomba |
| Machine learning models of non-invasive tests to predict MASH and fibrosis stage based on MAESTRO-NAFLD-1 and MAESTRO-NASH liver biopsies | Rohit Loomba |
Rezdiffra (resmetirom) is a once-daily, oral, liver-directed thyroid hormone receptor (THR)-β agonist designed to address key underlying causes of MASH. It was the first medication approved for the treatment of MASH in the U.S. and Europe. In the pivotal Phase 3 MAESTRO-NASH biopsy trial, Rezdiffra achieved both fibrosis improvement and MASH resolution primary endpoints. Rezdiffra also reduced liver stiffness, liver fat, liver enzymes and atherogenic lipids in the MAESTRO-NASH trial and improved health-related quality of life. At one year, 91% of patients treated with Rezdiffra 100mg achieved improvement or stabilization of liver stiffness as measured by vibrational-controlled transient elastography (VCTE), a test that is frequently used to monitor treatment response in clinical practice.
Rezdiffra 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. Rezdiffra is not approved in any geography for the treatment of patients with cirrhosis.
About MASH
Metabolic dysfunction-associated steatohepatitis (MASH) is a serious liver disease that can progress to cirrhosis, liver failure, liver cancer, the need for liver transplantation and premature mortality. MASH is the leading cause of liver transplantation in women and the second leading cause of all liver transplantation in the U.S., and the fastest-growing indication for liver transplantation in Europe.
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 to 17 times higher risk of liver-related mortality as compared to patients without fibrosis.
Patients with MASH 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.
As disease awareness improves and disease prevalence increases, the number of diagnosed patients F2 to F4c MASH is growing.
About Rezdiffra
What is Rezdiffra?
Rezdiffra is a prescribed medicine used along with diet and exercise to treat adults with metabolic dysfunction-associated steatohepatitis (MASH) with moderate to advanced liver scarring (fibrosis), but not with cirrhosis of the liver.
This indication is approved based on improvement of MASH 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 MASH.
- 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.
- A pregnancy safety study for women who take Rezdiffra during pregnancy collects information about the health of you and your baby. You or your healthcare provider can report your pregnancy by visiting https://pregnancyregistry.madrigalpharma.com/ or calling 1-800-905-0324.
- 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, 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.
What are the possible side effects of Rezdiffra?
Rezdiffra may cause serious side effects, including:
- liver injury (hepatotoxicity). Stop taking Rezdiffra and call your healthcare provider right away if you develop the following signs or symptoms of hepatotoxicity: tiredness, nausea, vomiting, fever, rash, your skin or the white part of your eyes turns yellow (jaundice) or stomach pain/tenderness.
- gallbladder problems. Gallbladder problems such as gallstones, or inflammation of the gallbladder, or inflammation of the pancreas from gallstones can occur with MASH and may occur if you take Rezdiffra. Call your healthcare provider right away if you develop any signs or symptoms of these conditions including nausea, vomiting, fever, or pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen to your back and the pain may happen with or without vomiting.
- The most common side effects of Rezdiffra include: diarrhea, nausea, itching, stomach pain, vomiting, dizziness and constipation.
These are not all the possible side effects of Rezdiffra. For more information, ask your healthcare provider or pharmacist.
