Inclusion criteria

Male or female Age between 18 and 75 years of age inclusive at the time of signing the informed consent
Established diagnosis of PBC according to the EASL criteria (European Association for the Study of the Liver 2009): A diagnosis of PBC can be made with confidence in adult patients with otherwise unexplained elevation of ALP and presence of anti-mitochondrial antibody (AMA≥1:40), and/or AMA type M2. A liver biopsy is not essential for the diagnosis of PBC in these patients, but allows activity and stage of the disease to be assessed.
Having a screening ALP serum level between 1.67 and 5x ULN inclusive.
Be on a stable dose of ursodeoxycholic acid (UDCA) 12-20 mg/kg/day for at least 3 months prior to Screening or intolerant of UDCA in the opinion of the investigator (no UDCA for at least 8 weeks prior to Screening).
Are not pregnant or breast feeding and do not plan to become pregnant or father a child during the study. Female subjects (of childbearing potential) must be willing to use two medically accepted forms of contraception throughout the study and must be willing to submit to pregnancy test(s). Male subjects must agree to use medically accepted contraception methods with their partners throughout the study as described above, unless they have had a prior vasectomy.
Has the ability to communicate adequately with the study staff and to comply with the requirements of the entire study, with the help of a caregiver, if applicable.
