Alcohol Consumption
Conditions
Brief summary
The main purpose of this study is to see whether heavy drinking will interfere with a specific pathway, called FXR signaling in the liver. The abnormality of this pathway may lead to liver injury in some patients who drink heavily.
Interventions
1 tablet of placebo, taken orally daily with water, approximately 30 minutes prior to breakfast for 4 weeks.
10 mg Obeticholic Acid (OCA) Study medication will be administered orally, once daily, approximately 30 minutes prior to breakfast for 4 weeks.

Eligibility
Inclusion criteria
* Individuals ≥ 21 to 65 years old * Able to provide informed consent & negative urine pregnancy test where appropriate * Healthy controls must have not consumed any alcohol within 3 months prior to the screening visit * Heavy alcohol drinking is defined as \> 40 grams per day on average in women and \> 60 grams per day on average in men for a minimum of 6 months * Women of child bearing potential should be willing to practice contraception throughout the treatment period
Exclusion criteria
* Active infection as evidenced by positive urine culture, blood culture, or pneumonia * Serum creatinine \> 1.5 mg/dL * Known co-existing infection with hepatitis C, hepatitis B, or HIV * Significant systemic or major illness including COPD, CHF and renal failure that in the opinion of the Investigator would preclude the patient from participating in and completing the study. * Participation in another investigational drug, biologic, or medical device trial within 30 days prior to Screening * Previous history of jaundice or signs of liver diseases such as spider angiomata, ascites, or history of esophageal varices or hepatic encephalopathy * Total bilirubin \> 2 mg/dl and INR \> 1.5 Page 20 of 37 * Women who are pregnant or nursing * Presence of any other disease or condition that is interfering with the absorption, distribution, metabolism, or excretion of drugs including bile salt metabolism in the intestine.
