Brief summary: The purpose of this study is to evaluate the efficacy and safety of vedolizumab intravenous (IV) in non-end-stage primary sclerosing cholangitis (PSC) participants with underlying inflammatory bowel disease (IBD).

Detailed description: The drug being tested in this study is called vedolizumab. Vedolizumab is being tested to treat people who have non-end-stage primary sclerosing cholangitis (PSC) with underlying inflammatory bowel disease (IBD). This study will look at changes in fibrosis staging in people who take vedolizumab.

The study will enroll approximately 258 patients. Participants will be randomly assigned (by chance, like flipping a coin) to one of the three treatment groups in ratio 1:1:1-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):

* Vedolizumab 300 mg once every 4 weeks (Q4W)
* Vedolizumab 300 mg once every 8 weeks (Q8W)
* Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient

All participants will be administered vedolizumab or placebo via intravenous infusion

This multi-center trial will be conducted worldwide. The overall time to participate in this study is up to 124 weeks. Participants will make multiple visits to the clinic and will be contacted by telephone 6 months after last dose of study drug for a follow-up assessment.

Eligibility criteria: Inclusion Criteria:

1. Has chronic cholestatic liver disease, of at least 6 months duration, with a subsequent diagnosis of primary sclerosing cholangitis (PSC), based on cholangiographic findings of intrahepatic and/or extrahepatic bile duct irregularities consistent with PSC.
2. Has a diagnosis of inflammatory bowel disease (IBD) (either ulcerative colitis \[UC\], Crohn's disease \[CD\], or IBD unclassified \[IBDU\]), established at least 3 months prior to enrollment by clinical and endoscopic evidence and corroborated by a histopathology report.
3. Has a liver stiffness transient elastography (TE) score of ≤14.3 kPa, as assessed by FibroScan.
4. Has had a colorectal cancer screen within 12 months of the Screening Visit with no signs of malignancy, dysplasia, or neoplasia.

Exclusion Criteria:

Hepatic and Gastrointestinal Exclusion Criteria

1. Has received any fibrates within 8 weeks of Screening.
2. Has high suspicion of cholangiocarcinoma, as indicated by an elevated Ca 19-9 value (\>129 U/mL) at screening.
3. Has evidence of overlap syndrome with autoimmune hepatitis or primary or secondary biliary cirrhosis or autoimmune cholangitis, as judged by the investigator.
4. Has evidence of alcoholic liver disease including history of alcoholic hepatitis.
5. Has a diagnosis of small duct PSC.
6. Has a Model for End-Stage Liver Disease (MELD) score \>12 at screening.
7. Has a Child-Pugh score \>7 (following adjustment for PSC diagnosis) at screening.
8. Has received a liver transplant.
9. Has evidence of autoimmune immunoglobin (Ig) IgG4-associated cholangitis, as defined by elevated serum IgG4 at least 2 x ULN (at screening), or IgG4/IgG1 ratio above 0.24.
10. Has undergone prior biliary surgery (laparoscopic or open surgery). Participants who have undergone cholecystectomy without surgical complications will be allowed provided the surgery was not done within 6 weeks prior to screening.
11. Has had 2 or more interventional treatments for dominant stricture (including stent placement/replacement) within 12 months prior to the Screening Visit.
12. Has evidence of cholangitis, requiring antibiotics, within 3 months prior to the Screening Visit \[short courses of antibiotics for no more than 5 days are allowed for stent placement or endoscopic retrograde cholangiopancreatography (ERCP) prophylaxis\].

    Infectious Disease Exclusion Criteria
13. Has chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.
14. Has positive hepatitis B core antibody (anti-HBc) at screening.
15. Has evidence of an active infection during the Screening Period.
16. Has any identified congenital or acquired immunodeficiency (eg, common variable immunodeficiency, human immunodeficiency virus \[HIV\] infection, organ transplantation).
17. Has active or latent tuberculosis (TB), regardless of treatment history, as evidenced by any of the following:

    1. History of TB.
    2. A positive diagnostic TB test within 30 days of enrollment defined as: 1. A positive QuantiFERON test or 2 successive indeterminate QuantiFERON tests (or, a positive T-SPOT TB test \[Japan only\]), OR
    3. Chest X-ray within 3 months of enrollment in which active or latent pulmonary TB cannot be excluded

    General Exclusion Criteria
18. Has had previous exposure to natalizumab, efalizumab, rituximab, or any other integrin antagonist.
19. Has received any of the following for the treatment of underlying disease within 30 days of screening:

    * Nonbiologic therapies (eg, cyclosporine, tacrolimus, thalidomide) other than those specifically listed in the protocol for the treatment of IBD.
    * An approved nonbiologic therapy in an investigational protocol.
20. Has, in the judgment of the investigator, clinically significant abnormal hematological parameters of hemoglobin, hematocrit, or erythrocytes at the Screening Visit.
21. Has any history of malignancy, except for the following: (a) adequately treated nonmetastatic basal cell skin cancer; (b) squamous cell skin cancer that has been adequately treated and that has not recurred for at least 1 year prior to randomization; and (c) history of cervical carcinoma in situ that has been adequately treated and that has not recurred for at least 3 years prior to randomization. Participant with remote history of malignancy (eg, \>10 years since completion of curative therapy without recurrence) will be considered based on the nature of the malignancy and the therapy received and must be discussed with the sponsor on a case-by-case basis prior to randomization.
