Study of IDN-6556 in Patients With Severe Alcoholic Hepatitis and Contraindications to Steroid Therapy

Phase 2

Terminated

• Conditions: Alcoholic Hepatitis
• Interventions: Drug: IDN-6556; Drug: Placebo

• Registration Number: NCT01912404
• Lead Sponsor: Conatus Pharmaceuticals Inc.

Brief Summary

The main purpose of the study is to test if taking a study drug called emricasan (also known as IDN-6556 and PF-03491390) will affect overall patient survival after one month of treatment.

Detailed Description

The study will also see if overall patient survival is affected at 6 months, and if the study drug improves liver function.

   2. Metabolic liver disease (abnormal ceruloplasmin levels)
   3. Vascular liver disease
   4. Drug induced liver disease Note: Concurrent viral hepatitis is not excluded.
