-- Study expected to provide proof-of-concept data in NASH for the first liver-directed, thyroid hormone receptor (THR) ß-selective agonist –
-- Primary endpoint is the reduction of liver fat, assessed by MRI-PDFF, at 12 weeks, with confirmation of NASH resolution by biopsy at 36 weeks --
CONSHOHOCKEN, Pa., Oct. 20, 2016 (GLOBE NEWSWIRE) -- Madrigal Pharmaceuticals, Inc. (Nasdaq:MDGL) today announced that the first patient has been dosed in its Phase 2 study of MGL-3196 for the treatment of non-alcoholic steatohepatitis (NASH). MGL-3196 is a first-in-class, oral, once-daily, liver-directed, thyroid hormone receptor (THR) ß-selective agonist medication.
“Thyroid hormone, through activation of its ß receptor, plays a central role in controlling lipid metabolism, impacting many health parameters from levels of serum cholesterol and triglycerides to the pathological buildup of fat in the liver,” said Paul A. Friedman, M.D., Chairman and CEO of Madrigal. “The lack of selectivity of older compounds limited their clinical utility, so we designed this study to provide clinical proof-of-concept for the role of highly-specific THR ß activation in regulating lipid metabolism in the liver to treat the cause of NASH. It will also allow us to confirm the value of assessing the early reduction of liver fat with imaging as a meaningful and predictive treatment endpoint.”
“NASH is the leading liver disease in the United States with a growing prevalence for which no FDA approved treatment is yet available,” said Dr. Stephen Harrison, Principal Investigator of the study as well as Medical Director for Pinnacle Clinical Research, San Antonio, Texas, and Visiting Professor of Hepatology, Oxford University. “We are hopeful that this novel approach, by targeting an underlying pathophysiologic mechanism of NASH, will eventually address a significant unmet need in this patient population.”
Becky Taub, M.D., CMO and Executive VP, Research & Development of Madrigal added, “Madrigal’s 36-week NASH study has a unique design based on the mechanism of action of MGL-3196 that allows us to determine the primary endpoint after 12 weeks of treatment, the percent change in hepatic fat fraction from baseline as measured by MRI-PDFF (magnetic resonance imaging-estimated proton density fat fraction), an imaging-based biomarker.”
The randomized, double-blind, placebo-controlled, multi-center Phase 2 study will enroll 117 patients 18 years of age and older with biopsy-confirmed NASH. Patients are randomized to receive either placebo or MGL-3196, twice as many receiving MGL-3196 as placebo. Efficacy will be confirmed at the end of the trial (36 weeks) by repeat MRI-PDFF and conventional liver biopsy to examine histological evidence for the resolution of NASH. Recent published data show a high correlation of reduction of liver fat measured by MRI-PDFF to NASH scoring on liver biopsy. Other secondary endpoints include changes in clinically relevant biomarkers at 12 and 36 weeks, improvement in fibrosis by at least one stage with no worsening of steatohepatitis, and safety and tolerability. Additional information about the study [NCT02912260] can be obtained at www.ClinicalTrials.gov.
NASH (non-alcoholic steatohepatitis) is a common liver disease in the United States and world-wide, unrelated to alcohol use, characterized by a build-up of fat in the liver, inflammation, and increasing fibrosis. Although people with NASH may feel well and often do not know they have the disease, NASH can lead to permanent damage, including cirrhosis, and impaired liver function. According to the National Institutes of Health (NIH), NASH affects approximately 2-5% of American adults,1 or more than 15 million people. It is the fastest growing reason for liver transplants and is also associated with an increasing incidence of liver cancer. There are currently no treatments approved by the U.S. Food and Drug Administration (FDA) for NASH.
About Madrigal Pharmaceuticals
Madrigal Pharmaceuticals, Inc. (Nasdaq:MGDL) is a clinical-stage biopharmaceutical company pursuing novel therapeutics that target a specific thyroid hormone receptor pathway in the liver, which is a key regulatory mechanism common to a spectrum of cardio-metabolic and fatty liver diseases with high unmet medical need.
