- Histologically confirmed chronic non-suppurative destructive cholangitis (CNSDC) with laboratory findings compatible with PBC
- Positivity for antimitochondrial antibodies (AMAs) with histological findings compatible with PBC but in the absence of characteristic histological findings of CNSDC
- No histological findings available, but positivity for AMAs as well as clinical findings and a course indicative of typical cholestatic PBC
2. Taking stable dose of ursodeoxycholic acid for at least 6 months (>= 600mg/day ) prior to Screening
3. Screening and Week 0 ALP values between 1.67 and 10 times upper limit normal
