    1. History of heavy alcohol abuse use: >40 g/day in females and >60 g/day in males for most days in a minimum period of 6 months
    2. Consumed alcohol within 6 weeks of entry into the study
    3. Biochemical parameters of severe disease as evidenced by MELD score >20 but <35, or MELD score 35-40 if the SOFA score is <10
  4. Willingness to utilize 2 reliable forms of contraception (for both males and females of childbearing potential) from screening to 1 month after the completion of study treatment
  5. Patients with established contraindications to steroid use including but not limited to the following:

    1. GI bleed
    2. Active infection, including spontaneous bacterial peritonitis, based on positive blood culture, urine culture, or chest x-ray (if positive, must have been on antibiotics for at least 24 hours prior to study entry)
    3. Acute pancreatitis (increased lipase > 3x ULN or radiologic evidence)
    4. Positivity for hepatitis B (HBsAg+) or C virus (HCV+), and
    5. Renal failure

Exclusion Criteria:

  1. Other or concomitant cause of liver disease as a result of:

    1. Autoimmune liver disease (positive anti-mitochondrial antibody and smooth muscle antibody, positive reading on anti-nuclear antibody titer >1:160)
    2. Metabolic liver disease (abnormal ceruloplasmin levels)
    3. Vascular liver disease
    4. Drug induced liver disease Note: Concurrent viral hepatitis is not excluded.
  2. Co-infection with human immunodeficiency virus (HIV)

  10. History or presence of clinically concerning cardiac arrhythmias, or prolongation of screening (pre-treatment) QT or QTc interval of >480 milliseconds (msec)
  11. Significant systemic or major illness other than liver disease, including coronary artery disease, cerebrovascular disease, pulmonary disease, renal failure, serious psychiatric disease, that, in the opinion of the Investigator would preclude the patient from participating in and completing the study
  12. Patients requiring the use of vasopressors or inotropic support
  13. Liver biopsy, if carried out, showing findings not compatible with alcoholic hepatitis
  14. Any patient that has received any investigational drug or device within 30 days of dosing or who is scheduled to receive another investigational drug or device in the course of the study Note: Investigational drug includes any drug that is used off-label.
  15. If female, known pregnancy, or has a positive urine or serum pregnancy test, or lactating/breastfeeding
  16. If male, if partner is known to be pregnant at time of entry into study or becomes pregnant while patient is on study drug or up to 1 month after completion of study drug
  17. Appropriate candidate for corticosteroid therapy
  18. Treatment for alcohol hepatitis within 1 month of study entry with use of corticosteroids for >1 week or corticosteroid use at the time of entry into the study.
