Summary
The primary hypothesis was that obeticholic acid (OCA) will cause a reduction in alkaline phosphatase levels in PBC participants, over a 12-week treatment period, as compared to placebo.
Eligibility Criteria
Inclusion Criteria
- Female participants must be postmenopausal, surgically sterile, or if premenopausal, be prepared to use 1 effective method of contraception with all sexual partners during the study and for 14 days after the end of dosing.
- Male participants must be prepared to use 1 effective method of contraception with all sexual partners during the study during the study unless they had a prior vasectomy.
- Proven or likely PBC, as demonstrated by the participant presenting with at least 2 of the following 3 diagnostic factors:
- History of increased alkaline phosphatase (ALP) levels for at least 6 months;
- Positive antimitochondrial antibody titer (>1: 40 titer on immunofluorescence or M2 positive by enzyme-linked immunosorbent assay) or PBC-specific antinuclear antibodies (antinuclear dot and nuclear rim positive);
- Liver biopsy consistent with PBC
- Screening ALP level between 1.5 and 10 × upper limit of normal (ULN).
Exclusion Criteria
- Administration of the following drugs at any time during the 3 months prior to screening for the study: ursodeoxycholic acid, colchicine, methotrexate, azathioprine, or systemic corticosteroids.
- Screening conjugated (direct) bilirubin >2 × ULN.
- Screening alanine aminotransferase or aspartate aminotransferase >5 × ULN.
- Screening serum creatinine >133 micromoles/liter (1.5 mg/deciliter).
History or presence of hepatic decompensation (for example, variceal bleeds, encephalopathy, or poorly controlled ascites).
- History or presence of other concomitant liver diseases including hepatitis due to hepatitis B or C virus infection, primary sclerosing cholangitis, alcoholic liver disease, definite autoimmune liver disease or biopsy proven nonalcoholic steatohepatitis.
- Pregnancy.
