Phase 3 Study of Obeticholic Acid in Patients With Primary Biliary Cirrhosis
A Phase 3, Double Blind, Placebo Controlled Trial and Long Term Safety Extension of Obeticholic Acid in Patients With Primary Biliary Cirrhosis
The investigational drug, Obeticholic Acid (OCA) is a modified bile acid and FXR agonist. FXR is a key regulator of bile acid synthesis and transport. Bile acids are used by the body to help with digestion. It is hypothesized that regular treatment with OCA will improve liver function in persons with Primary Biliary Cirrhosis (PBC).

    • Liver biopsy consistent with PBC
  2. At least 1 of the following qualifying biochemistry values:

    • ALP ≥ 1.67x upper limit of normal (ULN)
    • Total bilirubin > ULN but < 2x ULN

  12. Anticipated changes to current concomitant medications during the course of the trial
  13. History of alcohol abuse, defined as consumption of more than 210 mL of alcohol per week (i.e., the equivalent of 14 4-ounce (125 mL) glasses of wine or 14 12 ounce cans/bottles of beer), or other substance abuse within 1 year prior to Day 0
