E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To compare the efficacy and tolerability of a combination therapy with ursodeoxycholic acid (12-16 mg/kg body weight/d) plus budesonide (9 mg/d) vs. ursodeoxycholic acid (12-16 mg/kg body weight/d) plus placebo in the treatment of PBC.
- To study safety and tolerability in the form of adverse events and laboratory parameters.
- To assess patients’ Quality of Life.
