CONSHOHOCKEN, Pa., May 06, 2026 (GLOBE NEWSWIRE) -- Madrigal Pharmaceuticals, Inc. (Nasdaq: MDGL), a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), today reports first-quarter 2026 financial results and provides corporate updates.

Bill Sibold, Chief Executive Officer of Madrigal, stated: “2026 is off to a terrific start. Rezdiffra has achieved blockbuster status on a trailing-12-month net sales basis, reflecting broad physician adoption and high patient demand. The market dynamics continue to be very favorable for 2026 and for long-term growth due to a high unmet need in a rapidly growing market that has expanded nearly 50 percent to approximately 460,000 patients in the span of only two years. We’re continuing to steadily add patients, reinforcing our confidence in our robust growth expectations for Rezdiffra in 2026.”

Sibold continued: “We also strengthened our pipeline with a clinical stage siRNA asset targeting a mutation in the PNPLA3 gene that predisposes a significant portion of people with MASH to advanced liver fibrosis, including progression to cirrhosis. This new asset advances our strategy to develop next-generation combination therapies across the spectrum of disease. With our strong cash position and intellectual property protection for Rezdiffra expected into 2045, we are well-positioned to maintain our leadership in MASH, supported by the differentiated clinical profile of Rezdiffra as the only approved liver-directed therapy for this disease, our growing commercial success and an expanding, industry-leading MASH pipeline.”

First Quarter 2026 and Recent Corporate Updates

• Madrigal adds clinical-stage siRNA asset targeting PNPLA3 mutation
  • On May 5, Madrigal announced a licensing agreement with Arrowhead Pharmaceuticals, Inc. for global rights to ARO-PNPLA3, a clinical stage GalNAc-conjugated small interfering RNA (siRNA) asset designed to reduce expression of PNPLA3, a genetically validated driver of MASH.
  • ARO-PNPLA3 targets MASH patients who are homozygous for a mutation in the PNPLA3 gene, which is highly prevalent among Hispanic patients and represents approximately 30% of patients with moderate to advanced fibrosis (consistent with stages F2 and F3).
  • Data from a Phase 1 trial of ARO-PNPLA3 demonstrated up to a 46% reduction in liver fat (as measured by MRI-PDFF) at 12 weeks following a single dose at the highest dose level tested in PNPLA3 I148M homozygous patients.
• Expanded pipeline with global rights to six pre-clinical siRNA programs
  • In February 2026, Madrigal expanded its MASH pipeline with six innovative siRNA programs, providing the potential for a genetically targeted approach, combined with the broad efficacy of Rezdiffra, to create the next generation of MASH therapies.
  • Preclinical development is underway.
• Strong scientific presence at the upcoming EASL Congress
  • Madrigal will present 8 abstracts at the European Association for the Study of Liver (EASL) Congress, taking place May 27-30, 2026, in Barcelona, Spain.
  • Accepted abstracts include a poster featuring a secondary analysis from Madrigal’s MAESTRO-NASH/NAFLD1 trials showing that Rezdiffra reduced Lp(a) and LDL-C in patients with MASH, supporting its potential to reduce cardiovascular risk independent of baseline statin use, as well as two posters sharing real-world efficacy data for patients on Rezdiffra for up to one year.

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. It is 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 with F2 to F4c MASH is growing.

About Madrigal
Madrigal Pharmaceuticals, Inc. (Nasdaq: MDGL) is a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), a liver disease with high unmet medical need. Madrigal’s medication, Rezdiffra (resmetirom), is a once-daily, oral, liver-directed THR-β agonist designed to target key underlying causes of MASH. Rezdiffra was the first medication approved by both the FDA and European Commission for the treatment of MASH with moderate to advanced fibrosis (F2 to F3). An ongoing Phase 3 outcomes trial is evaluating Rezdiffra for the treatment of compensated MASH cirrhosis (F4c). For more information, visit www.madrigalpharma.com.
