Madrigal Pharmaceuticals Provides Corporate Update and Reports 2021 Third Quarter Financial Results

Several abstracts with data from the open-label arm of the Phase 3 MAESTRO-NAFLD-1 study accepted for presentation at AASLD’s upcoming The Liver Meeting® 2021

CONSHOHOCKEN, Pa., Nov. 04, 2021 (GLOBE NEWSWIRE) -- Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL) today provides a summary of corporate accomplishments and reports its third quarter 2021 financial results.

Paul Friedman, M.D., Chief Executive Officer of Madrigal, stated, “Throughout the third quarter, the Madrigal team continued to progress MAESTRO-NASH, the pivotal serial liver biopsy study and a key component of the Phase 3 program for resmetirom for patients with non-alcoholic steatohepatitis, NASH. We remain on track to complete the double-blind portion of our Phase 3 non-invasive imaging and biomarker study, MAESTRO-NAFLD-1, and report topline data by year-end, with additional topline data rollout in early 2022. We will also be presenting additional data from the open-label portion of this study at the American Association for the Study of Liver Diseases (AASLD) The Liver Meeting® on November 12-15^th.”

Becky Taub, M.D., Chief Medical Officer and President of Research & Development at Madrigal stated, “Data from the recently completed 52 week open-label arm of the MAESTRO-NAFLD-1 study will be presented at AASLD and provides our most informed insights to date regarding the effects of resmetirom in presumed NASH patients, using a variety of non-invasive tests relevant to clinical practice. The double-blinded MAESTRO-NAFLD-1 and MAESTRO NASH studies readouts over the forthcoming months will further inform our understanding of how to identify and monitor NASH patients with significant fibrosis.”

Dr. Taub added, “In October, in recognition of Liver Awareness Month, we announced our alliance with the Fatty Liver Foundation, a leading patient advocacy organization focused on the diagnosis, treatment and support of individuals with non-alcoholic fatty liver disease or NAFLD and NASH. Our alliance with the Foundation is in support of their NAFLD Screening Fund and aligns with our commitment to advance the use of non-invasive techniques to improve the diagnosis and staging of NAFLD and NASH and identify people at risk of NASH earlier in the course of their disease.”

Several abstracts summarizing data from the open-label arms of the MAESTRO-NAFLD-1 study have been accepted for presentation at AASLD’s The Liver Meeting® 2021. Madrigal will host a webcast and conference call on Tuesday, November 16^th at 8.00 AM ET to summarize and discuss the data that are being presented.

Financial Results

As of September 30, 2021, Madrigal had cash, cash equivalents and marketable securities of $299.1 million, compared to $284.1 million at December 31, 2020. The increase in cash and marketable securities was due to net proceeds of $151.2 million from sales of common stock via our at-the-market (ATM) program, partially offset by cash used to support operations of $135.9 million.

Operating expenses were $63.2 million and $177.9 million for the three and nine month periods ended September 30, 2021, compared to $58.8 million and $147.1 million in the comparable prior year periods.

Research and development expenses for the three and nine month periods ended September 30, 2021 were $54.9 million and $152.3 million, compared to $53.3 million and $131.4 million in the comparable prior year periods. The increase is attributable primarily to additional activities related to the Phase 3 clinical trials, and an increase in head count.

General and administrative expenses for the three and nine month periods ended September 30, 2021 were $8.3 million and $25.6 million, compared to $5.5 million and $15.8 million in the comparable prior year periods. The increase is attributable primarily to increases in commercial preparation activities, including an increase in headcount and an increase in non-cash stock compensation.

Interest income for the three and nine month periods ended September 30, 2021 was $0.1 million and $0.3 million, compared to $0.8 million and $3.9 million in the comparable prior year periods. The decrease in interest income was due primarily to decreased interest rates.

About Resmetirom
Thyroid hormone, through activation of its β-receptor in hepatocytes, plays a central role in liver function impacting a range of health parameters from levels of serum cholesterol and triglycerides to the pathological buildup of fat in the liver. Thyroid hormone receptor (THR)-β action in the liver is key to proper function of the liver, including regulation of mitochondrial activity such as breakdown of liver fat and control of the level of normal, healthy mitochondria. Patients with NASH have reduced levels of thyroid hormone activity in the liver with resultant impaired hepatic function, in part due to the inflamed state of the liver that causes degradation of thyroid hormone.

To exploit the thyroid hormone receptor (THR)-β pathway for therapeutic purposes in liver and cardio-metabolic diseases, it is important to avoid activity at the THR-α receptor, the predominant systemic receptor for thyroid hormone that is responsible for activity outside the liver including in heart and bone. The lack of selectivity of older thyromimetic compounds, chemically-related toxicities and undesirable distribution in the body led to safety concerns. Madrigal recognized that greater selectivity for thyroid hormone receptor (THR)-β and liver targeting might overcome these challenges and deliver the full therapeutic potential of THR-β agonism. Resmetirom has been shown to be highly selective based on 1) THR-β receptor functional selectivity based on both in vitro and in vivo assays and 2) specific uptake into the liver, its site of action, virtually avoiding any uptake into tissues outside the liver. In short- and long- term human and animal studies, resmetirom has been confirmed to be safe and devoid of activity at the THR-α receptor and without impact on bone or cardiac parameters. Resmetirom does not impact the thyroid axis hormones, including the central thyroid axis. Madrigal believes that resmetirom is the first orally administered, small-molecule, liver-directed, truly β-selective THR agonist.

About the Phase 3 Registration Program for the Treatment of NASH (Non-alcoholic steatohepatitis)
Madrigal is currently conducting two Phase 3 Clinical trials, MAESTRO-NASH and MAESTRO-NAFLD-1, to demonstrate the safety and efficacy of resmetirom for the treatment of NASH.

MAESTRO-NASH is a Phase 3 multi-center, double-blind, randomized, placebo-controlled study of resmetirom in patients with liver biopsy confirmed NASH and was initiated in March 2019. The study targets enrollment of 900 patients with biopsy-proven NASH (fibrosis stage 2 or 3, at least 450 fibrosis stage 3), randomized 1:1:1 to receive resmetirom 80 mg once a day, 100 mg once a day, or placebo. After 52 weeks of treatment a second biopsy is performed. The primary surrogate endpoint on biopsy will be NASH resolution, with at least a 2-point reduction in NAS (NASH Activity Score), and with no worsening of fibrosis. Two key secondary endpoints are liver fibrosis reduction of at least one stage, with no worsening of NASH on liver biopsy, and lowering of LDL-cholesterol [ClinicalTrials.gov/NCT03900429]. Madrigal announced achievement of the planned target enrollment on June 30, 2021.

The first 900 patients in the MAESTRO-NASH study will continue on therapy after the initial 52-week treatment period; and up to another 1,100 patients are to be added using the same randomization plan and the study is expected to continue for up to 54 months to accrue and measure hepatic clinical outcome events including progression to cirrhosis on biopsy (52 weeks and 54 months) and hepatic decompensation events.

MAESTRO-NAFLD-1 is a 52-week Phase 3 multi-center, double-blind, randomized, placebo-controlled study of resmetirom, and was initiated in December 2019 in patients with non-alcoholic fatty liver disease (NAFLD), presumed NASH. The primary endpoint for this study is to evaluate the safety and tolerability of resmetirom. Completion of enrollment of over 1,200 patients into the study was announced in November 2020. Top-line data from the study is targeted by end of year 2021.

Patients in MAESTRO-NAFLD-1 are randomized 1:1:1 to receive resmetirom 80 mg once a day, 100 mg once a day, or placebo. MAESTRO-NAFLD-1 also includes a 100 mg resmetirom open label arm. 52 week data were presented from the open label arm at The International Liver Congress™ 2021 in June and demonstrated that resmetirom is safe and well-tolerated at 100mg per day [view press release here]. MAESTRO-NAFLD-1 (unlike MAESTRO-NASH), does not include a liver biopsy and represents a “real-life” NASH study. NASH or presumed NASH is documented using historical liver biopsy or non-invasive techniques including FibroScan and magnetic resonance imaging, proton density fat fraction (MRI-PDFF) respectively. Using non-invasive measures, MAESTRO-NAFLD-1 is designed to provide incremental safety information to support the NASH indication as well as provide additional data regarding clinically relevant key secondary efficacy endpoints to better characterize the potential clinical benefits of resmetirom on cardiovascular and liver related endpoints. These key secondary endpoints include LDL-cholesterol, apolipoprotein B and triglyceride (TG) lowering; reduction of liver fat as determined by MRI-PDFF; and reduction of PRO-C3, a NASH fibrosis biomarker. [ClinicalTrials.gov/NCT04197479]. Additional secondary and exploratory endpoints will be assessed including reduction in liver enzymes, FibroScan scores and other fibrosis and inflammatory biomarkers.

Data from the 52 week portion of MAESTRO-NASH, together with data from MAESTRO-NAFLD-1 and other data, including safety parameters, will form the basis for a potential subpart H submission to FDA for accelerated approval for the treatment of NASH.
