Inclusion Criteria
  • Participant has a PBC diagnosis as demonstrated by the presence of ≥2 of the following three diagnostic criteria (Lindor et al, 2019; Hirschfield et al, 2017):

    1. History of ALP above ULN for at least 6 months
    2. History of positive antimitochondrial antibody (AMA) titer or positive PBC-specific antinuclear antibody (ANA) titers
    3. Historical liver biopsy consistent with PBC
  • Has PBC with cirrhosis Child-Pugh grade A (well-compensated disease; score 5 to 6) at Screening. Group 2 (PBC w/ CIRR CP-A) only

  • Male or female participant is ≥18 years of age at consent.

  • Able to understand and comply with study requirements and procedures and provide written informed consent.

  • Meet all other inclusion criteria outlined in the clinical study protocol.

Exclusion Criteria
  • Female subject of childbearing potential who is known to be pregnant, has a positive pregnancy test (serum test, or urine test that is confirmed by a positive serum pregnancy test), or is lactating and breastfeeding, or planning to become pregnant or breastfeed during the study.
  • Subject has had ongoing conditions that may affect drug absorption such as gastroparesis, intestinal obstruction, severe gastritis, severe gastric reflux syndrome, conditions causing frequent vomiting and/or diarrhea.
  • Subject who has participated in another investigational drug, biologic, or medical device study within five half-lives of the agent (or within 8 weeks when half-life is unknown) prior to the first dose of study drug, or prior participation in an investigational antibody drug study within 6 months prior to the first dose of study drug. Participation in noninterventional studies (eg, observational studies, registries) is allowed.
  • Meet any other exclusion criteria outlined in the clinical study protocol.
