4. Patients receiving azathioprine for intestinal bowel disease are eligible to participate in the study provided that they have had no IBD exacerbations for at least 6 months.
5. Females of childbearing potential must have a negative serum pregnancy test [β human chorionic gonadotropin (β-hCG)] during screening and negative urine pregnancy test at the baseline/Day 0 visit.
6. Sexually active females must be postmenopausal, surgically sterile, or if premenopausal, be prepared to use an effective method (≤ 1% failure rate) of contraception during the trial.

11. Access to phone for scheduled calls from study site.
12. Must agree to comply with the study protocol procedures and provide written informed consent.

Exclusion Criteria:

1. Small duct PSC (clinical biochemical and histological features compatible with PSC, but having a normal cholangiogram).
2. Presence of a dominant stricture unless brushings and/or biopsies of the stricture are negative for dysplasia or malignancy within 6 months of screening.
3. Surgical or endoscopic biliary tree interventions for treatment of clinically significant strictures within 6 months of screening.
4. IBD flare (Mayo UC disease activity score > 5 including endoscopic evaluation) within 3 months prior to screening.
5. Secondary cause of sclerosing cholangitis (e.g., choledocholithiasis, post-surgical biliary stricture, intra-arterial chemotherapy, recurrent pancreatitis, IgG4 associated cholangiopathy, AIDS cholangiopathy).
6. AST or ALT ≥ 5 x ULN at screening.
7. History or presence of any other concomitant significant liver disease as assessed by the Investigator.
8. Medical conditions that may cause nonhepatic increases in ALP (e.g., Paget's disease).
9. Known history of human immunodeficiency virus (HIV) infection.
10. The anticipated need for a surgical procedure within 20 weeks from randomization.
11. Any female who is pregnant or lactating or who is planning to become pregnant within 20 weeks of randomization.

17. Any other conditions or abnormalities which, in the opinion of the Investigator or Medical Monitor, may compromise the safety of the subject, or interfere with the subject participating in or completing the study.
