  • Known history of alpha-1-antitrypsin deficiency
  • Use of an experimental treatment for NASH within the past 6 months
  • Use of immunosuppressant (eg, corticosteroids) for more than 2 weeks in duration within 1 year prior to Screening and during the course of the study
  • Use of experimental or unapproved drugs within a year of Screening
  • Any other condition(s) (including cardiovascular diseases) that would compromise the safety of the subject or compromise the quality of the clinical study, as judged by the Principal Investigator (PI)

  • Clinical suspicion of advanced liver disease or cirrhosis
  • Coexisting liver or biliary diseases, such as primary sclerosing cholangitis (PSC), choledocholithiasis, acute or chronic hepatitis, autoimmune hepatitis, alcoholic liver disease, acute infection of bile duct system or gall bladder, history of gastrointestinal bleeding (secondary to portal hypertension), cirrhosis

  • Subject has received an investigational agent or vaccine within 30 days, or a biological product within 3 months or 5 elimination half-lives (whichever is longer) prior to the planned intake of study drug. NOTE: Flu vaccine will be allowed upon Medical Monitor's approval
  • Use of a new statin regimen from Screening and throughout study duration. NOTE: Subjects on a stable dose of statins for at least three months prior to Screening are allowed. No dose modification during the study will be allowed.
  • Current use of fibrates. Note: Subjects who discontinued fibrates for at least 3 months before Screening can participate
