Advancing MGL-3196 as

Madrigal Pharmaceuticals, Inc. (Nasdaq: MDGL) 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. The Company has advanced its lead candidate, MGL-3196, a first-in-class, orally administered, small-molecule, liver-directed, thyroid hormone receptor (THR) β-selective agonist, through Phase 2 clinical trials in non-alcoholic steatohepatitis (NASH) and heterozygous familial hypercholesterolemia (HeFH). Primary and key secondary endpoints were achieved including reduction of liver fat on a sensitive non-invasive imaging test, lowering of multiple atherogenic lipids including LDL-cholesterol and triglycerides, and resolution of NASH on liver biopsy. Based on evidence of broad activity and a favorable safety profile, Madrigal plans to initiate a Phase 3 clinical program in NASH, and a second Phase 3 clinical program in a broader segment of patients with dyslipidemia, including potentially patients with earlier stages of fatty liver disease who, like the later stage NASH patients, are at high risk of cardiovascular disease.
