• Fourth-quarter and full-year 2024 Rezdiffra net sales of $103.3 million and $180.1 million, respectively
• As of year-end 2024, more than 11,800 patients on Rezdiffra
• Reports cash, cash equivalents, restricted cash and marketable securities of $931.3 million at December 31, 2024
• Announces new two-year data for the active-treatment open-label compensated MASH cirrhosis (F4c) arm of the Phase 3 MAESTRO-NAFLD-1 trial
• Company to host conference call today, February 26, 2025, at 8 a.m. EST

CONSHOHOCKEN, Pa., Feb. 26, 2025 (GLOBE NEWSWIRE) — Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL), a biopharmaceutical company focused on delivering novel therapeutics for metabolic dysfunction-associated steatohepatitis (MASH), today reports fourth-quarter and year-end 2024 financial results and reviews business highlights.

Bill Sibold, Chief Executive Officer of Madrigal, stated, “Looking back on 2024, I’m incredibly proud of what we accomplished. We secured FDA approval for Rezdiffra, the first medicine approved for MASH, in March; executed a first-in-disease launch with remarkable results; and are well positioned for strong performance again in 2025 and beyond.”

Sibold continued, “The U.S. launch of Rezdiffra has energized the MASH community, and we’re positioned to extend our leadership. Today, we’re sharing new two-year analyses from an active-treatment open-label extension arm of our Phase 3 MAESTRO-NAFLD-1 trial that demonstrate Rezdiffra continues to improve key markers of MASH fibrosis out to two years in patients with compensated MASH cirrhosis (F4c). These results add to the growing body of evidence supporting Rezdiffra’s potential benefit in this high-risk patient population, for which there is no approved therapy. A positive read out in our fully enrolled Phase 3 MAESTRO-NASH OUTCOMES trial could make Rezdiffra the first and only treatment for F2 to F4c MASH, and the only therapy with outcomes data this decade.”

New Two-Year Data from the Active-Treatment Open-Label Compensated MASH Cirrhosis Arm of the Rezdiffra Phase 3 MAESTRO-NAFLD-1 Trial

• MAESTRO-NAFLD-1 was a double-blind placebo-controlled, randomized Phase 3 safety trial conducted to support regulatory approval of Rezdiffra. The trial includes an active-treatment open-label extension arm in patients with compensated MASH cirrhosis. Madrigal previously reported one-year results for this active treatment arm.
• Today, the Company is announcing, two-year results (n=101):
  • The patient cohort achieved a mean 6.7 kPa reduction in liver stiffness as measured by vibration-controlled transient elastography (VCTE); this represents the largest VCTE reduction reported in an F4c MASH patient population to date. This reduction was statistically significant as compared to baseline.
  • 51% of patients achieved a ≥ 25% reduction in liver stiffness as measured by VCTE. A reduction of this magnitude has been associated with reduced progression to end-stage liver disease.
  • Rezdiffra’s safety and tolerability profile was consistent with other Rezdiffra clinical trials with a low discontinuation rate due to adverse events.
• Madrigal plans to present these data and additional findings from the active-treatment open-label cirrhosis arm of the MAESTRO-NAFLD-1 trial at a future medical meeting.
• The results further support the potential benefit of Rezdiffra in patients with compensated MASH cirrhosis and the potential success of the ongoing MAESTRO-NASH OUTCOMES trial, a double blind, placebo-controlled, event-driven trial in F4c, for which data are anticipated in 2027.

2024 Highlights

• Landmark FDA approval of Rezdiffra
  • In February 2024, Rezdiffra Phase 3 MAESTRO-NASH trial 52-week results were published in The New England Journal of Medicine; the paper was subsequently chosen as one of the journal’s 14 notable scientific research articles of 2024.
  • In March 2024, Madrigal announced FDA approval of Rezdiffra for the treatment of adults with noncirrhotic MASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).
  • In April 2024, Rezdiffra became commercially available as the first and only approved therapy for MASH.
• Expert guidelines recommend Rezdiffra as first-line therapy for MASH
  • In June 2024, the European Association for the Study of the Liver (EASL) Congress updated their practice guidelines to recommend Rezdiffra as a first-line therapy for MASH, subject to regulatory approval in Europe.
  • In October 2024, the American Association for the Study of Liver Diseases (AASLD), a leading organization of scientists and health care professionals committed to preventing and curing liver disease, updated their practice guidelines to recommend Rezdiffra as a first-line therapy for MASH and implemented recommendations regarding its use for clinicians.
• Driving future growth through European expansion
  • In March 2024, Madrigal announced that the marketing authorization application (MAA) for resmetirom for the treatment of MASH with liver fibrosis was validated and 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 is expected in mid-2025.
  • Madrigal expects to launch Rezdiffra in Europe on a country-by-country basis commencing with Germany in the second half of 2025, pending EMA approval, which would make it the first approved therapy for patients with MASH liver fibrosis in Europe.
• Driving future growth through indication expansion
  • In October 2024, Madrigal announced completion of enrollment in the MAESTRO-NASH OUTCOMES trial, an event-driven trial evaluating Rezdiffra in patients with F4c, an advanced and underserved patient population. Positive results could position Rezdiffra to become the only treatment for F2 to F4c MASH and the only therapy with outcomes data in MASH this decade.
• Strong presence at key liver meetings
  • In June 2024, Madrigal presented 10 abstracts at the EASL congress, including noninvasive test (NIT) data that demonstrated 91% of patients achieved improvement or stabilization of liver stiffness out to three years.
  • In November 2024, Madrigal had a significant presence at the AASLD Liver Meeting. Eleven Madrigal abstracts were presented at the meeting, including two oral presentations of new analyses from the Phase 3 MAESTRO-NASH trial of Rezdiffra.

Fourth-Quarter and Full-Year 2024 Financial Results

• Total revenues: The Company generated fourth-quarter and full-year 2024 net revenues of $103.3 million and $180.1 million, respectively. No product sales were recognized during the comparable prior year period.
• Operating Expenses: Fourth-quarter and full-year 2024 operating expenses were $170.3 million and $678.0 million, respectively, compared to $117.2 million and $380.5 million in the comparable prior year periods.
  • Cost of sales: Fourth-quarter and full-year 2024 cost of sales were $3.4 million and $6.2 million, respectively. Cost of sales were not recognized during the comparable prior year periods given that no product sales were recorded.
  • R&D Expense: Fourth-quarter and full-year 2024 R&D expense was $25.6 million and $236.7 million, respectively, compared to $70.6 million and $272.4 million in the comparable prior year periods. Research and development expenses decreased by $35.6 million in 2024 due primarily to a reduction in clinical trial accruals and the change in accounting for inventory costs following FDA approval of Rezdiffra in March 2024, partially offset by increases in headcount.
  • SG&A Expense: Fourth-quarter and full-year 2024 SG&A expense was $141.2 million and $435.1 million, respectively, compared to $46.5 million and $108.1 million in the comparable prior year periods. Selling, general and administrative expenses increased by $326.9 million in 2024 due primarily to increases for commercial launch activities for Rezdiffra, including a corresponding increase in headcount, and an increase in stock compensation expense.
• Interest Income: Fourth-quarter and full-year 2024 interest income was $11.1 million and $46.7 million, respectively, compared to $9.0 million and $19.6 million in the comparable prior year periods. The increase in interest income was due primarily to higher principal balances and interest rates in 2024.
• Interest Expense: Fourth-quarter and full-year 2024 interest expense was $3.5 million and $14.7 million, respectively, compared to $4.0 million and $12.7 million in the comparable prior year periods. The increase in interest expense in 2024 was primarily the result of a higher average outstanding principal balance during the period under the Madrigal’s loan facility.
• Cash, Cash Equivalents, Restricted Cash and Marketable Securities: As of December 31, 2024, Madrigal had cash, cash equivalents, restricted cash and marketable securities of $931.3 million, compared to $634.1 million at December 31, 2023. This increase was primarily attributable to the $659.9 million of net proceeds we received from our underwritten public offering in March 2024.

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.
