•- Signed informed consent
•- Male or female patients =18 years of age
•- Ursodeoxycholic acid = 10 mg/kg body weight/d treatment for at least 6 months prior to inclusion and responsive (Normalisation of AP or reduction of AP=40 % after onset of UDCA)
•- At least 2 out of the following 3 criteria:
•Histologically proven non-cirrhotic liver disease compatible with early-stage PBC (stage I +II)

•- Negative pregnancy test at baseline visit in female patients of childbearing potential
•- Women of child-bearing potential have to apply appropriate contraceptive methods, e.g. hormonal contraception, intrauterine device (IUD), double-barrier method of contraception (e.g. use of condom and spermicide), sexual abstinence, partner has undergone vasectomy and subject is in a monogamous relationship.
