A Phase 4, Double-Blind, Randomized, Placebo-Controlled Study Evaluating the Pharmacokinetics and Safety of Obeticholic Acid in Patients With Primary Biliary Cholangitis and Moderate to Severe Hepatic Impairment

This Phase 4, randomized, double-blind, placebo-controlled study will evaluate the pharmacokinetics (PK) and safety of OCA treatment in participants with PBC and moderate to severe hepatic impairment over a 48-week treatment period. Participants who have completed their 48-week double blind treatment period will continue double-blind treatment until all randomized participants have completed their 48-week treatment period and the database for that period is locked. An open-label extension study in which all participants receive OCA will be considered following review of blinded safety and PK data.
