E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of three doses of norUDCA vs. placebo for the treatment of PSC;
To identify efficacious norUDCA dose(s) for the treatment of PSC for further evaluation in phase III |
|
E.2.2 | Secondary objectives of the trial |
To study safety and tolerability (adverse events, laboratory parameters) of norUDCA;
To assess quality of life |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Signed informed consent,
2. Male or female patients ≥ 18 and < 80 years,
4. Alkaline Phosphatase ≥ 1.5 x ULN at baseline,
6. Women of child-bearing potential have to apply during the entire duration of the study a highly effective method of birth control, which is defined as one which results in a low failure rate (i.e., less than 1% per year) when used constantly and correctly such as implants, injectables, combined oral contraceptive method, or some IUDs. Women of non-childbearing potential may be included if surgically sterile or post-menopausal for at least 2 years. The investigator is responsible for determining whether the subject has this adequate birth control for study participation.

Note: Patients who present with anti-HBc+ only, may be included if they are HBV-DNA negative)
• Primary Biliary Cirrhosis, (AMA-positive)
• Wilson’s Disease
• Haemochromatosis
• Autoimmune Hepatitis
• Chronic alcoholic consumption (daily consumption >30g/d)
• Biopsy proven NASH
• Cholangiocarcinoma,
2. Treatment with any of the following drugs within the last 3 months prior to baseline: any glucocorticosteroids (including budesonide), azathioprine or other immunosuppressive drugs (e.g. cyclophosphamide, cyclosporine, methotrexate, tacrolimus, 6-mercaptopurine), chlorambucil, pentoxyfylline, penicillamine, pirfenidone, fibrates, biologics (e.g., anti-tumor necrosis factor-alpha therapy), or rifampicin,
5. Child B/C liver cirrhosis,
12. Total bilirubin > 3.0 mg/dl (>51,3 µmol/L), at screening or baseline,
13. Both total bilirubin levels > ULN within the last 6 months prior to baseline and a rise of this level by more than 50% within the last 6 months prior to baseline,
14. Albumin < 36 g/L, at screening or baseline,
16. Any relevant systemic disease (e.g., AIDS),
17. Abnormal renal function (Cystatin C > 1.15xULN) at screening and/or at baseline visit,
18. TSH > ULN at screening,
20. Any active malignant disease,
21. Known intolerance/hypersensitivity to study drug, or drugs of similar chemical structure or pharmacological profile
