Description
Key Inclusion Criteria:
Definite or probable PBC diagnosis as demonstrated by the presence of ≥ 2 of the following 3 diagnostic factors:
- History of elevated alkaline phosphatase levels for at least 6 months
- A positive anti-microbial antibody (AMA) titer or, if AMA negative or in low titer (<1:80), PBC-specific antibodies
- Liver biopsy consistent with PBC
- Taking UDCA for at least 12 months (stable dose for ≥ 3 months) prior to Day 0 or unable to tolerate UDCA (no UDCA for ≥ 3 months prior to Day 0).
- Contraception: Female participants must have been postmenopausal, surgically sterile, or if premenopausal, were prepared to use ≥ 1 effective (≤ 1% failure rate) method of contraception during the trial and until at least 30 days after the last dose of Investigational Product.
- Must have provided written informed consent and agreed to comply with the trial protocol.
Key Exclusion Criteria:
- Participants with decompensated PBC (as determined by the Investigator).
- Severe pruritus or systemic treatment for pruritus (for example, treatment with bile acid sequestrants or rifampicin) within 2 months of Day 0.
History or presence of other significant liver diseases including:
- Active or chronic Hepatitis B or C virus infection
- Primary sclerosing cholangitis
- Alcoholic liver disease
- Definite autoimmune liver disease or overlap hepatitis
- Nonalcoholic steatohepatitis
Note: Participants with Gilbert's disease or those with a history of hepatitis B who were currently antigen negative and seroconverted were not considered exclusionary.
- Uncontrolled diabetes or other uncontrolled or unstable medical condition that may have interfered with trial results.
Administration of any of the following medications as specified below:
- Prohibited 28 days prior to Day 0: bile acid sequestrants including cholestyramine, colesevelam, colestipol or omega-3 fatty acid containing dietary supplements
- Prohibited 3 months prior to Day 0 and throughout trial participation: serum-lipid modifying agents including 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, fenofibrate or other fibrates, nicotinic acid and derivatives, ezetimibe, Vitamin E (other than as standard dietary supplement)
- Prohibited 6 months prior to Day 0 and throughout the trial participation: azathioprine, colchicine, cyclosporine, methotrexate, mycophenolate mofetil, pentoxifylline; budesonide and other systemic corticosteroids; potentially hepatotoxic drugs (including α-methyl-dopa, sodium valproic acid, isoniazide, or nitrofurantoin)
- Prohibited 12 months prior to Day 0 and throughout the trial participation: antibodies or immunotherapy directed against interleukins or other cytokines or chemokines
- Planned change in diet or exercise habits during participation in the trial.
- Presence or history of clinically significant cardiac arrhythmias that may have prohibited the participant from participating in the trial.
- If female: known pregnancy, or had a positive urine pregnancy test (confirmed by a positive serum pregnancy test), or lactating.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: OCA: 10 mg
Obeticholic acid, oral administration, 10 milligrams (mg), 8 weeks
|
All participants were treated with OCA (oral administration, 10 mg, once daily [QD]) for 8 weeks and continued their prestudy dose of ursodeoxycholic acid (UDCA).
After completion of the 8-week Primary Treatment Phase of the study and the 4-week follow-up period, during which time participants did not take OCA, all eligible participants were offered the opportunity to enter an open-label, long-term safety extension phase, during which they could receive 10 mg OCA QD for up to 2 years.

Median Change From Baseline In Enhanced Liver Fibrosis (ELF) Score
Time Frame: Baseline, Month 12, Month 24/EOT
|
Change in ELF was calculated as ELF score at the end of the study minus ELF score prior to the intervention (at baseline). A decrease in the ELF score was considered good as it reflected a decrease in liver fibrosis, and an increase in ELF score was considered bad as it reflected an increase in liver fibrosis. Change in ELF scores ranged from -0.56 (good) to + 0.68 (bad). |
