Phase 3 Study of Obeticholic Acid in Patients With Primary Biliary Cirrhosis

The study included 2 phases: a 12-month randomized, double-blind (DB), placebo-controlled, parallel group phase, followed by a long-term safety extension (LTSE) phase up to 5 years. Participants from the 12-month DB phase, including those who received placebo, were eligible to participate in the open-label LTSE phase. The Month 12 visit from the DB phase served as the Day 1 visit of the LTSE phase. After completion of the 12-month DB phase all participants were offered the opportunity to enter an open-label LTSE for up to 5 years beginning at 5 mg OCA. Data for the LTSE phase is reported by the randomized dose group assigned in the DB phase.
