Madrigal Announces New Clinical Data Demonstrating Rezdiffra™ (resmetirom) Significantly Improved Multiple Noninvasive Tests and Portal Hypertension Risk in Patients with Compensated MASH Cirrhosis

Madrigal Announces New Clinical Data on Rezdiffra™ (resmetirom) for Compensated MASH Cirrhosis

On May 10, 2025, Madrigal Pharmaceuticals, Inc. announced positive two-year results from the open-label compensated Metabolic Dysfunction-Associated Steatohepatitis (MASH) cirrhosis (F4c) arm of the Phase 3 MAESTRO-NAFLD-1 trial for Rezdiffra™ (resmetirom), presented at the European Association for the Study of the Liver (EASL) Congress in Amsterdam (GlobeNewswire, BioSpace). The data demonstrated significant improvements in multiple noninvasive tests (NITs) and reduced risk of clinically significant portal hypertension (CSPH) in patients with compensated MASH cirrhosis, a condition with high unmet medical need due to its progression to liver failure, cancer, or transplantation (Madrigal Investor Relations). This development connects to your prior queries on systemic interventions (e.g., Borno’s fuel ban, Sahara Reporters; Saudi Arabia’s India-Pakistan mediation, NDTV), reflecting themes of addressing critical challenges through targeted measures.

Key Findings from the MAESTRO-NAFLD-1 Trial

  • Study Details:
  • Trial Arm: Open-label, active treatment arm of the Phase 3 MAESTRO-NAFLD-1 trial, involving 122 patients with compensated MASH cirrhosis (F4c) (GlobeNewswire).
  • Duration: Two years of treatment with Rezdiffra, a once-daily, oral, liver-directed thyroid hormone receptor-beta (THR-β) agonist (Madrigal Investor Relations).
  • Presentation: 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,” by Naim Alkhouri, M.D. on May 10, 2025, at 13:15 CEST (BioSpace).
  • Clinical Outcomes:
  • Liver Stiffness: Patients achieved a mean 6.7 kPa reduction in liver stiffness (from a baseline of 25 kPa) measured by vibration-controlled transient elastography (VCTE), the largest reported in an F4c MASH cohort. This was statistically significant compared to baseline, with 51% of patients achieving a ≥25% reduction, associated with reduced progression to end-stage liver disease (Madrigal Investor Relations, GlobeNewswire).
  • Other NITs: Significant improvements in:
    • Liver fat content, measured by imaging (GlobeNewswire).
    • Fibrosis biomarkers, indicating reduced scarring (BioSpace).
    • Liver volume, suggesting decreased inflammation (GlobeNewswire).
    • Fibrosis scores, showing stabilization or reversal of disease progression (BioSpace).
  • Portal Hypertension Risk: 65% of patients with CSPH or probable CSPH at baseline shifted to lower-risk categories, reducing the likelihood of life-threatening complications like liver decompensation (GlobeNewswire).
  • Expert Commentary:
  • Naim Alkhouri, M.D.: “Rezdiffra demonstrated broad, sustained efficacy across multiple noninvasive parameters at two years. A high, statistically significant percentage of patients with CSPH or probable CSPH at baseline shifted to lower risk categories” (GlobeNewswire).
  • David Soergel, M.D., Madrigal’s Chief Medical Officer: “Lower THR-β activity in the liver is predictive of hepatic decompensation in patients with MASH, so there is a strong mechanistic rationale supporting the potential of Rezdiffra… These two-year open-label data… add important clinical evidence” (GlobeNewswire).
  • Bill Sibold, CEO: “Patients with compensated MASH cirrhosis who develop clinically significant portal hypertension are at greatly elevated risk of experiencing life-threatening complications… so there is an urgent need to advance new treatment strategies” (BioSpace).
  • Ongoing Trials:
  • The MAESTRO-NASH OUTCOMES trial, fully enrolled with 845 patients as of October 2024, evaluates Rezdiffra’s impact on liver decompensation events in compensated MASH cirrhosis. Positive results could support an additional FDA indication for F4c MASH and full approval for noncirrhotic MASH (F2–F3) (Madrigal Investor Relations, BioSpace).

Context and Significance

  • About MASH:
  • MASH (formerly nonalcoholic steatohepatitis, NASH) is a severe liver disease driven by fat accumulation, inflammation, and fibrosis, often linked to comorbidities like obesity, type 2 diabetes, or hypertension (Madrigal Investor Relations).
  • Compensated Cirrhosis (F4c): An advanced stage with significant scarring but no decompensation (e.g., ascites, variceal bleeding). It carries a 42-fold higher risk of liver-related mortality and is a leading cause of liver transplantation, especially among women (Madrigal Investor Relations).
  • Prevalence: Approximately 1.5 million U.S. patients are diagnosed with MASH, with 525,000 having moderate to advanced fibrosis (F2–F3). The F4c population is smaller but critically underserved (Madrigal Investor Relations).
  • Rezdiffra’s Current Status:
  • FDA Approval: In March 2024, Rezdiffra became the first and only FDA-approved therapy for noncirrhotic MASH with moderate to advanced fibrosis (F2–F3), based on the MAESTRO-NASH trial showing 25.9–29.9% NASH resolution and fibrosis improvement (BioSpace, NEJM).
  • Noncirrhotic Focus: Rezdiffra is not yet approved for MASH cirrhosis (F4c), but the MAESTRO-NAFLD-1 and OUTCOMES trials aim to expand its indication (GlobeNewswire).
  • Global Efforts: A marketing authorization application is under review by the European Medicines Agency (EMA), with a decision expected by mid-2025 (Madrigal Investor Relations).
  • Market and Sentiment:
  • X Posts: Reflect optimism about Rezdiffra’s potential:
    • @WallStSai (May 5, 2025): Noted Rezdiffra’s efficacy exceeding expectations, with physicians and patients reporting improvements in liver stiffness, fat, and enzymes (@WallStSai).
    • @MadrigalPharma (May 9, 2025): Highlighted the EASL presentation as advancing MASH care (@MadrigalPharma).
    • @WallStSai (May 5, 2025): Suggested Rezdiffra may “halt or reverse disease progression” in F4c MASH (@WallStSai).
  • Commercial Progress: By December 2024, 11,800 patients were on Rezdiffra, with 70% of 6,000 top MASH prescribers having prescribed it, though only 5% of the 315,000 target population (F2–F3) is reached, indicating growth potential (@WallStSai).

Critical Analysis

  • Strengths:
  • First-in-Class: Rezdiffra’s FDA approval for F2–F3 MASH and promising F4c data position it as a leader in a field with no approved cirrhosis therapies (BioSpace).
  • Noninvasive Testing: The trial’s use of NITs (e.g., VCTE, biomarkers) aligns with industry shifts away from invasive biopsies, improving patient access and monitoring (BioSpace).
  • Mechanistic Rationale: As a THR-β agonist, Rezdiffra targets lipid metabolism and fibrosis, addressing MASH’s root causes, supported by prior MAESTRO-NASH success (NEJM).
  • Public Health Impact: Reducing CSPH risk could lower liver transplantation needs, a pressing issue as MASH is the leading transplant cause in women (Madrigal Investor Relations).
  • Weaknesses and Risks:
  • Open-Label Limitation: The MAESTRO-NAFLD-1 F4c arm lacks a placebo control, reducing certainty about Rezdiffra’s effect size versus natural progression (GlobeNewswire).
  • Regulatory Hurdles: Rezdiffra is not yet approved for F4c MASH, and the OUTCOMES trial’s event-driven design introduces uncertainty in timing and outcomes (Madrigal Investor Relations).
  • Competitive Landscape: GLP-1 agonists (e.g., Wegovy, Zepbound) show MASH benefits via weight loss, potentially challenging Rezdiffra’s market share, though their efficacy in F4c is less studied (BioSpace).
  • Disinformation Risk: X posts (@WallStSai) may overstate Rezdiffra’s impact (e.g., “halt or reverse” claims), similar to your UNC rumor query’s narrative concerns (SI.com). Unverified enthusiasm could mislead investors or patients (@WallStSai).
  • Disinformation Dynamics:
  • Like your India-Pakistan query (NDTV), where competing narratives complicated mediation, MASH treatment discussions on X (@WallStSai, @MadrigalPharma) risk oversimplification. Claims of “exceeding expectations” lack granular data (@WallStSai).
