Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects with diagnosis of large duct PSC of more than 24 weeks' duration
• Subjects that have no significant clinical concern for cholangiocarcinoma based on clinical, laboratory or imaging findings
• Subjects with serum Alkaline phosphatase (ALP) greater than 1.5 × Upper limit of normal (ULN) in Screening blood tests.
• Subjects receiving Ursodeoxycholic acid (UDCA) must receive a stable dose for ≥12 weeks prior to Screening
• Subjects with concomitant inflammatory bowel disease (IBD) is allowed but not required, and must meet the following stability criteria.
• Subjects with ulcerative colitis: Must be either in remission or have mild disease. Must have recent colonoscopy with biopsy confirming no dysplasia or colorectal cancer or history of colectomy.
• Subjects with Crohn's Disease must be in remission as defined by a Crohn's Disease Activity Index (CDAI) \< 150.
• Subjects receiving concomitant medication for IBD, dose must be stable ≥12 weeks prior to screening and dose should remain stable during DB portion of the study
• Subjects receiving concomitant medication for their PSC must be on stable therapy ≥12 weeks prior to randomization and plan to remain on that stable dose during the DB portion of the study
• Female subjects of childbearing potential, must have a negative serum pregnancy test prior to starting study treatment and must have agree to highly effective method of contraception from the Screening Visit throughout the study period including 18 weeks post last dose
• Male subjects, if not vasectomized, must agree to use barrier contraception from screening through to study completion and for 90 days from the last dose of study drug

You may not qualify if:

• Subjects with presence of documented secondary sclerosing cholangitis on prior clinical investigations
• Subjects with presence of competing etiology of liver disease.
• Subjects with possible overlap syndrome with autoimmune hepatitis are excluded if the Investigator considers autoimmune hepatitis as the predominant liver injury
• Subjects with small duct PSC in the absence of large duct disease
• Subjects with percutaneous biliary drain or bile duct stent or subjects who had required biliary drainage within 12 weeks of Screening
• Subjects that have undergone prior biliary surgery other than those who at the time of screening are more than 6 weeks after cholecystectomy without surgical complications
• Subjects with evidence of liver cirrhosis, as determined by local transient elastography values of ≥ 14.4 kPa obtained during the Screening period. In case of a fibrosis staging discrepancy between a recent (≤ 12 months) liver biopsy staging and the transient elastography results, eligibility will be based on the liver biopsy staging.
• History of cirrhosis and/or hepatic impairment (Child-Pugh classes A, B and C), and/or hepatic decompensation including ascites, encephalopathy, or variceal bleeding
• Subjects who have undergone or are planned for liver transplantation or with current model of end stage liver disease
• Subjects with Aspartate aminotransferase (AST) or Alanine aminotransferase (ALT) values \> 5 × ULN as determined at Screening
• Subjects who show 'clinically significant' lab changes at Screening
• Subjects with serum total bilirubin values \> 3 × ULN at Screening
• Subjects with known Gilbert's syndrome or a history of elevations in unconjugated (indirect) bilirubin \>ULN
• Subjects with international normalized ratio (INR) \>1.5 which does not correct on vitamin K replacement, in the absence of anticoagulants
• Subjects with serum creatinine \> 1.4 mg/dL (123 μmol/L) and/or a platelet count \< 100 × 109 /L
