A Randomized, Double-Blind, Placebo-Controlled Phase 4 Study to Evaluate the Efficacy and Safety of Entyvio (Vedolizumab IV) in the Treatment of Chronic Pouchitis (EARNEST)

The purpose of this study is to assess the efficacy and safety of vedolizumab intravenous
(IV) in participants with a proctocolectomy and ileal pouch anal anastomosis for ulcerative
colitis (UC) who have developed chronic or recurrent pouchitis, or require continuous
antibiotic treatment.

Vedolizumab is being tested to treat people who have chronic pouchitis. This study will look
at the healing of inflammation of ileal pouch in people who take vedolizumab as compared to
those receiving a matching placebo. The study will enroll approximately 110 patients.
Participants will be randomly assigned to one of the two treatment groups—which will remain
undisclosed to the patient and study doctor during the study (unless there is an urgent
medical need):

- Vedolizumab 300 mg IV

- Placebo

All participants will receive an intravenous infusion at Weeks 0, 2, 6, 14, 22, and 30 along
with concomitant antibiotic treatment with ciprofloxacin 500 mg twice daily through Week 4.

This multicenter trial will be conducted in North America and Europe. The overall time to
participate in treatment and efficacy assessment of this study is 34 weeks. Participants will
make multiple visits to the clinic, plus a final visit 18 weeks after the last dose of study
drug for a safety follow-up assessment (up to Week 48). Participants will also participate in
a long-term follow-up, by phone after the last dose of study drug up to Week 56.

Inclusion Criteria:

1. In the opinion of the investigator, the participant is capable of understanding and
complying with protocol requirements.

2. The participant or, when applicable, the participant's legally acceptable
representative signs and dates a written, informed consent form and any required
privacy authorization prior to the initiation of any study procedures.

3. Has a history of ileal pouch anal anastomosis (IPAA) for ulcerative colitis (UC)
completed at least 1 year prior to the Day 1 (Randomization) Visit.

4. Has pouchitis that is chronic or recurrent, defined by an modified pouchitis disease
activity index (mPDAI) score ≥5 assessed as average from 3 days immediately prior to
the Baseline endoscopy and a minimum endoscopic subscore of 2 (outside the staple or
suture line) with either (a) ≥3 recurrent episodes within 1 year prior to the
Screening Period treated with ≥ 2 weeks of antibiotic or other prescription therapy,
or (b) requiring maintenance antibiotic therapy taken continuously for ≥4 weeks
immediately prior to the Baseline Endoscopy Visit.

5. Agrees to take ciprofloxacin (500 mg twice daily) on Day 1 and through Week 4,
regardless of the previous treatment and to stop any previous antibiotic therapy on
Day 1 of the study (additional courses of antibiotics will be allowed, as needed, for
flares after Week 14.)

6. A male participant who is nonsterilized and sexually active with a female partner of
childbearing potential agrees to use a barrier method of contraception (e.g., condom
with spermicide) from signing of informed consent throughout the duration of the study
and for 18 weeks after last dose. The female partner of a male subject should also be
advised to use a highly effective method of contraception

7. A female participant of childbearing potential who is sexually active with a
nonsterilized male partner agrees to use a highly effective method of contraception
from signing of informed consent throughout the duration of the study and for 18 weeks
after last dose.

Exclusion Criteria:

Gastrointestinal Exclusion Criteria

1. Has Crohn's disease (CD), or CD of the pouch.

2. Has irritable pouch syndrome (IPS).

3. Has isolated or predominant cuffitis.

4. Has mechanical complications of the pouch (eg, pouch stricture or pouch fistula).

5. Currently requires or has a planned surgical intervention for UC during the study.

6. Has diverting stoma

Infectious Disease Exclusion Criteria 1. Has evidence of an active infection (eg, sepsis,
cytomegalovirus, or listeriosis) during Screening.

2. Has active or latent tuberculosis (TB), regardless of treatment history, as evidenced by
any of the following:

1. A diagnostic TB test performed within 30 days of Screening or during the Screening
Period that is positive, as defined by:

1. A positive QuantiFERON test or 2 successive indeterminate QuantiFERON tests OR

2. A tuberculin skin test reaction ≥10 mm (≥5 mm in participants receiving the
equivalent of >15 mg/day prednisone).

OR

2. Chest X-ray within 3 months prior to Day 1 that is suspicious for pulmonary TB, and a
positive or 2 successive indeterminate QuantiFERON test within 30 days prior to
Screening or during the Screening Period.

3. Has chronic hepatitis B virus (HBV) infection* or chronic hepatitis C virus (HCV)
infection** or a known history of human immunodeficiency virus (HIV) infection (or is
found to be seropositive at Screening) or subject is immunodeficient (eg, due to organ
transplantation, history of common variable immunodeficiency, etc).

* Participants who are positive for hepatitis B virus surface antigen (HBsAg) will be
excluded. For participants who are negative for HBsAg but are positive for either
surface antibodies and/or core antibodies, HBV DNA polymerase chain reaction will be
performed and if any test result meets or exceeds detection sensitivity, the
participant will be excluded.

- If participant is HCV antibody positive, then a viral load test will be
performed. If the viral load test is positive then the participant will be
excluded.

4. Has evidence of active infection with C difficile during Screening (to be
confirmed by laboratory test)
