Subject must be willing and able to adhere to the assessments, visit schedule, prohibitions and restrictions, as described in this protocol

Exclusion Criteria:

Laboratory Screening Results:

AST >5 x ULN
ALT >5 x ULN
Patients with Gilbert's syndrome will not be allowed due to interpretability of bilirubin levels

Suspected to have relevant nonalcoholic fatty liver disease (NAFLD) as based on the judgment of the Investigator at Screening
Use of immunosuppressants known to have an effect on the liver of patients with PBC (eg, colchicine, methotrexate, azathioprine, or systemic steroids) in the three months preceding screening
Current use of fibrates, including fenofibrates. Note: Subjects who discontinued fibrates for at least 3 months before Screening can participate
Use of an experimental treatment for PBC within the past 6 months

Use of a new statin regimen from Screening and throughout study duration. NOTE: Subjects on a stable dose of statins for at least 3 months prior to Screening are allowed. No dose modification during the study will be allowed.
Use of immunosuppressants (eg, systemic corticosteroids) for more than 2 consecutive weeks in duration within 1 year prior to Screening.
