Primary Outcomes
Outcome Description
Progression of liver fibrosis was defined as having a ≥ 1-stage increase from baseline in fibrosis according to the Ludwig classification at Blinded Phase Week 96. The stages of fibrosis was assessed according to Ludwig classification. Ludwig classification fibrosis stages range from 0 to 4, with higher scores indicating greater fibrosis (0=no fibrosis, 4=cirrhosis).
Outcome Measure
Percentage of Participants With Progression of Liver Fibrosis at Blinded Phase Week 96

Secondary Outcomes
Outcome Description
An AE was any untoward medical occurrence in a clinical study participant administered a study drug that does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a study drug, whether or not the AE is considered related to the study drug. For Blinded Study Phase and OLE Phase, TEAEs were defined as 1 or both of the following: Any AEs with an onset date on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug and/or any AEs leading to premature discontinuation of study drug.
Outcome Time Frame
First dose date in the Blinded Phase up to 100.3 weeks plus 30 days
Outcome Measure
Percentage of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs) in The Blinded Phase

Outcome Description
The PSC-PRO addressed the severity of common everyday symptoms of PSC (eg, pruritus, fatigue, and right upper quadrant abdominal discomfort); and their functional impact (eg, on physical function, activities of daily living, and work productivity, etc). PSC-PRO module 1 - PSC symptoms contains a total of 12 questions asking about the severity of specific PSC symptoms on a scale of 0 (no symptoms) to 10 (symptoms as bad as you could imagine) with a 24-hour recall period. The total score, which is computed as 12 times the average of nonmissing scores of the 12 questions, can potentially range between 0 and 120, with higher scores indicating more severe symptoms. A positive change from baseline indicates worsening of symptoms.
Outcome Time Frame
Baseline, Blinded Phase Week 96
Outcome Measure
Change From Baseline in Primary Sclerosing Cholangitis (PSC) Symptoms - Module 1 Based on Disease-specific Patient Reported Outcome (PSC-PRO) at Blinded Phase Week 96
Outcome Description
The Enhanced Liver Fibrosis (ELF™) test is a composite of three serum biomarkers of hepatobiliary fibrosis: hyaluronic acid, procollagen III amino-terminal peptide, and tissue inhibitor of metalloproteinase. A typical range for ELF™ test scores in PSC is between 6 and 14. Higher ELF™ test scores are associated with more severe liver disease. A positive change from baseline indicated worsening of fibrosis.
Outcome Time Frame
Baseline, Blinded Phase Week 96
Outcome Measure
Change From Baseline in Enhanced Liver Fibrosis (ELF™ ) Test Score at Blinded Phase Week 96
Outcome Description
Change in liver stiffness was measured by FibroScan® scores. FibroScan measures liver scarring by measuring the stiffness of the liver. It's normally between 2 and 6 kPa. Many people with liver disease(s) have a result that's higher than the normal range. Higher scores indicate increased scarring of the liver. A positive change from baseline indicates severe liver disease(s).
