Name of Sponsor(s):
Takeda Development Center Americas, Inc.

Takeda Development Center Asia, Pte. Ltd.
Takeda Pharmaceutical Company, Ltd.
Compound:
Vedolizumab SC
Title of Protocol: A Phase 3, Randomized, Double-Blind, 
Placebo-Controlled Study, With a Vedolizumab IV Reference Arm, to 
Evaluate the Efficacy and Safety of Vedolizumab Subcutaneous as 
Maintenance Therapy in Subjects With Moderately to Severely Active 
Ulcerative Colitis Who Achieved Clinical Response Following Open-Label 
Vedolizumab Intravenous Therapy
IND No.:
118980
EudraCT No.:
2015-000480-14
Study Number: MLN0002SC-3027
Phase: 3
Study Design:
This is a pivotal, phase 3, multicenter, multinational, randomized, double-blind, double-dummy, placebo-controlled 
trial, including a vedolizumab intravenous (vedolizumab IV) reference arm, designed to evaluate the efficacy and 
safety of maintenance treatment with vedolizumab subcutaneous (vedolizumab SC) in adult subjects with moderately 
to severely active ulcerative colitis (UC) who achieved a clinical response at Week 6 following open-label therapy 
with 300 mg vedolizumab IV administered at Weeks 0 and 2. The study includes a vedolizumab IV reference arm to 
allow for within study descriptive comparisons on efficacy, safety, and immunogenicity between the two vedolizumab 
presentations.
Moderately to severely active UC is defined as a complete Mayo score of 6 to 12 points with endoscopic subscore of 
≥2. Subjects that are tumor necrosis factor-alpha (TNF-α) antagonist naïve or with TNF-α antagonist failure will be 
included, ensuring that approximately 50% of subjects with TNF-α antagonist failure are enrolled. Subjects with 
previous use of TNF-α antagonist but not failed will NOT be enrolled.
Primary Objectives:

To assess the effect of vedolizumab SC maintenance treatment on clinical remission at Week 52 in subjects with 
moderately to severely active UC who achieved clinical response at Week 6 following administration of 
vedolizumab IV at Weeks 0 and 2.
Secondary Objectives:

To determine the effect of vedolizumab SC maintenance treatment on mucosal healing at Week 52 in subjects 
who achieved clinical response at Week 6 following administration of vedolizumab IV at Weeks 0 and 2.

To determine the effect of vedolizumab SC maintenance treatment on durable clinical response at Week 52 in 
subjects who achieved clinical response at Week 6 following administration of vedolizumab IV at Weeks 0 and 2.

To determine the effect of vedolizumab SC maintenance treatment on durable clinical remission at Week 52 in 
subjects who achieved clinical response at Week 6 following administration of vedolizumab IV at Weeks 0 and 2.

To determine the effect of vedolizumab SC maintenance treatment on corticosteroid free remission at Week 52 in 
subjects who achieved clinical response at Week 6 following administration of vedolizumab IV at Weeks 0 and 2.
Subject Population: Adult subjects with UC, aged 18-80 years inclusive.
Number of Subjects: 
Approximately 400 subjects enrolled to enable approximately 188 subjects 
to be randomized for maintenance treatment.
Number of Sites: 
Approximately 250 sites globally.

Dose Level(s):
Vedolizumab SC, 108 mg
Vedolizumab IV, 300 mg
Route of Administration:
Subcutaneous
Intravenous
Duration of Treatment:
52-week treatment period
Period of Evaluation:
The study includes a 4-week (28-day) 
Screening Period, a 6-week open-label 
vedolizumab IV Induction Phase, a 
46-week randomized, double-blind, 
double-dummy, placebo-controlled 
Maintenance Phase with vedolizumab 
SC or vedolizumab IV with a final visit 
at Week 52.
Subjects who do not participate in the 
open-label extension (OLE) study will 
be required to participate in a Final 
Safety Visit 18-weeks after the last 
study drug dose (Week 50 or early 
termination [ET]) and a long-term 
follow-up (LTFU) safety survey by 
telephone, 6 months after the last dose 
of study drug.
Main Criteria for Inclusion:
The subject has a diagnosis of UC established at least 6 months prior to screening, by clinical and endoscopic evidence 
and corroborated by a histopathology report.
The subject has moderately to severely active UC as determined by a complete Mayo score of 6-12 with an endoscopic 
subscore ≥2 within 10 days prior to the first dose of study drug.
The subject has evidence of UC extending proximal to the rectum (≥15 cm of involved colon).
The subject has demonstrated an inadequate response to, loss of response to, or intolerance of at least 1 of the 
following agents: immunomodulators, corticosteroids, or TNF-α antagonists.
Main Criteria for Exclusion:
The subject has had extensive colonic resection, subtotal or total colectomy.
The subject has any evidence of an active infection during screening. 
The subject has a positive progressive multifocal leukoencephalopathy (PML) subjective checklist at Screening (or at 
Week 0 before the administration of study drug). 
The subject has received any investigational or approved biologic or biosimilar within 60 days or 5 half-lives of 
screening, whichever is longer.
The subject has had prior exposure to vedolizumab.
The subject has had prior exposure to natalizumab, efalizumab, or rituximab.
Main Criteria for Evaluation and Analyses: 
The primary endpoint for this study is the proportion of subjects with clinical remission, defined as a complete Mayo 
score of ≤2 points and no individual subcore >1 point, at Week 52.
Secondary endpoints for this study are:

Proportion of subjects with mucosal healing (defined as Mayo endoscopic subscore of ≤1 point) at Week 52.

Proportion of subjects with durable clinical response (defined as clinical response at Weeks 6 and 52, where 

Vedolizumab SC
Study No. MLN0002SC-3027
Page 14 of 109
Protocol Incorporating Amendment No. 05

clinical response is defined as a reduction in complete Mayo score of ≥3 points and ≥30% from Baseline (Week 0) 
with an accompanying decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 
point).

Proportion of subjects with durable clinical remission (defined as clinical remission at Weeks 6 and 52).

Proportion of subjects with corticosteroid-free remission (defined as subjects using oral corticosteroids at 
Baseline (Week 0) who have discontinued oral corticosteroids and are in clinical remission at Week 52). 
Statistical Considerations:
All statistical testing will be performed at 2-sided 0.05 level of significance. To control the overall Type I error rate for 
the comparison between vedolizumab SC and placebo groups for the primary and secondary endpoints, the statistical 
inference for the first secondary endpoint will only be performed if the primary endpoint is statistically significant and 
so on for each subsequent secondary endpoint. 
All dichotomous efficacy endpoints will be analyzed using Cochran-Mantel-Haenszel tests for risk differences, 
stratified by randomization stratum. All subjects with missing data for determination of endpoint status will be 
considered as a nonresponder in the analysis.
Sample Size Justification: 
Assuming a clinical remission rate of 42% for vedolizumab and 16% for placebo at Week 52, a sample size of 
94 subjects in the vedolizumab SC group, 47 subjects in the placebo group will provide 90% power at 2-sided 0.05 
level of significance. To ensure a randomized sample size of 188 subjects, assuming 47% of the subjects entering 
induction will achieve clinical response at Week 6, approximately 400 subjects will need to be enrolled into the study.

INTRODUCTION
4.1
Background
4.1.1
Diseases and Current Treatments 
Inflammatory bowel disease (IBD) is a chronic, relapsing, inflammatory disorder of the 
gastrointestinal (GI) tract that includes 2 entities, namely ulcerative colitis (UC) and Crohn’s 
disease (CD). 
UC is characterized by diffuse, superficial inflammation of the colonic mucosa that begins in the 
rectum and extends proximally to involve any contiguous length of colon. The prevalence of UC is 
approximately 200/100,000 of the United States population and approximately 150/100,000 of the 
population in Western Europe [1-3] and 63.6/100,000 of the population in Japan [4]. A genetic 
contribution to the disease is indicated by the increased incidence of UC (of 30 to 100 times that of 
the general population) among first-degree relatives of patients with UC. The characteristic 
pathology is one of chronic inflammation characterized by large numbers of lymphocytes and 
histiocytes in the diseased mucosa and submucosa with an acute inflammatory infiltrate composed 
of neutrophils variably present.
Clinical manifestations of UC include diarrhea, typically bloody, as well as abdominal pain, fecal 
urgency, and incontinence. Systemic features such as fever, weight loss, malaise, and fatigue are 
indicators of more extensive disease. Extra-intestinal manifestations such as uveitis, arthritis, 
ankylosis spondylitis, or primary sclerosing cholangitis may also be seen in conjunction with IBD. 
The diagnosis of UC is usually made by the clinical presentation and key features of the history, 
physical examination, in combination with laboratory and imaging studies.
Current treatments have been effective for many patients with UC but have numerous limitations 
for patients with moderately to severely active disease. 5-aminosalicylates (5-ASAs) are the 
mainstay of UC pharmacotherapy for induction and maintenance of remission for patients with 
mild to moderate disease, but are less effective in moderate to severe disease. [5,6]. 
Corticosteroids are often required for the 1/3 of patients who fail to respond to 5-ASAs [7,8]. 
While highly effective for induction of remission, corticosteroids are not recommended for 
maintenance of remission and carry significant undesirable side effects, including osteoporosis, 
glucose intolerance, and increased risk of infection. 
Immunomodulatory agents, including 6-mercaptopurine and azathioprine, have a role in 
maintenance of remission in moderately to severely active UC. Their relatively slow onset of 
action precludes their use during flares of disease, and the use of these agents has been reported to 
potentially increase the risk of lymphoma in patients with IBD [9]. Other severe adverse events 
(AEs) associated with use of immunomodulators include cytopenias, hepatitis, and infection.
Intravenous (IV) cyclosporine has a role in the management of severely active UC; however, it is 
impractical in non-hospitalized patients, requires intense monitoring, and may cause irreversible 
nephrotoxicity, all of which limit its use.

Monoclonal antibodies (mAbs) directed against tumor necrosis factor-alpha (TNF-α) have been 
approved for the treatment of UC in many countries world-wide, including infliximab (Remicade), 
which is administered by IV infusion, and adalimumab (Humira) and golimumab (Simponi), 
which are administered by subcutaneous (SC) injection [10-12]. These agents have substantially 
improved the care of patients with UC by inducing and maintaining remission and decreasing the 
need for hospitalizations and surgeries, and other complications. Although TNF-α antagonists 
represent an important addition to the UC pharmacologic armamentarium, they are effective in 
only a subset of patients, with roughly 2/3 of patients in controlled trials not in remission at the end 
of the first year of therapy [13,14]. Induction of remission with infliximab occurs in only 31% to 
39% of patients with UC [15] and durable clinical remission (ie, defined as clinical remission at 
Weeks 8, 30, and 54) occurs in only 26% of patients with UC. In addition, controlled studies have 
demonstrated that, after failure of 1 TNF-α antagonist, a patient’s response to a second TNF-α 
antagonist is substantially lower [16]. The TNF-α antagonists are also associated with a number of 
serious safety concerns based on their suppression of systemic immunity, including reactivation of 
tuberculosis (TB); various bacterial, viral, fungal, and opportunistic infections; and malignancies, 
such as hepatosplenic T cell lymphoma [10,11].
Failure of pharmacological therapy leads to colectomy in 9% to 35% of patients with UC within 
5 years. Colectomy is considered to be an important adjunct treatment for refractory UC; however, 
colectomy with ileal pouch anal anastomosis (the standard surgical therapy) has many limitations 
and is associated with its own set of complications, including high stool frequency [17], female 
infertility [18], and a cumulative incidence of pouchitis of 50% at 10 years [19]. The limitations of 
current therapies for UC indicate that there is a significant need for safer and more effective 
therapies.
4.1.2
Vedolizumab
Vedolizumab (also known as MLN0002) is a novel recombinant humanized mAb composed of 
2 light chains of the subclass and 2 immunoglobulin (Ig) G1 heavy chains. Vedolizumab binds 
specifically to the human lymphocyte integrin 47. The α4β7integrin mediates lymphocyte 
trafficking to GI mucosa and gut-associated lymphoid tissue (GALT) through adhesive interaction 
with mucosal addressin cell adhesion molecule-1 (MAdCAM-1), which is expressed on the 
endothelium of mesenteric lymph nodes and GI mucosa [20-23]. As a result, vedolizumab impairs 
the migration of gut-homing leukocytes into GI mucosa [24] and acts as a gut-selective 
immunomodulator.
Vedolizumab IV (also known as ENTYVIO; KYNTELES; Vedolizumab for Injection, for 
Intravenous Use; Vedolizumab Powder for Concentrate for Solution for Infusion; or MLN0002 
IV) has been granted marketing approval in several regions, including the United States (US) and 
European Union (EU). Vedolizumab IV is approved for the treatment of adult patients with 
moderately to severely active UC and CD, who have failed conventional treatment, such as 
immunomodulators, corticosteroids, or TNF-α antagonists. The approved dosing and 
administration regimen is 300 mg vedolizumab IV infused intravenously at Weeks 0 and 2, then 
once every 8 weeks (Q8W) thereafter, beginning at Week 6.

Vedolizumab SC (also known as Vedolizumab Injection, for Subcutaneous Use; Vedolizumab 
Solution for Injection in Pre-filled Syringe; or MLN0002 SC) is a new liquid presentation that has 
been developed for SC administration. 
 
 
 
 
 
Therefore, the nonclinical and clinical information from studies with vedolizumab 
IV are considered relevant.
As of 19 May 2015 (data lock point), more than 3600 subjects have received at least 1 dose of 
vedolizumab across all studies in the clinical development program. Phase 3 placebo-controlled 
studies enrolled 2427 subjects with UC or CD, of whom 1434 subjects were administered 300 mg 
of vedolizumab IV for induction followed by once every 4 weeks (Q4W) or Q8W for up to a total 
of 52 weeks and 488 subjects were administered 300 mg vedolizumab for induction only [25-27]. 
As of 19 May 2015, vedolizumab exposure has extended for ≥12 months in 1667 subjects, 
≥24 months in 1306 subjects, ≥36 months in 935 subjects, ≥48 months in 676 subjects, 
≥60 months in 267 subjects, and ≥72 months in 26 subjects. Based on the most recent drug 
shipment data (19 November 2015), the cumulative patient exposure to vedolizumab since its 
marketing approval in May 2014 is estimated to be approximately 25,831 patient-years.
Previously conducted clinical studies have characterized the efficacy, safety, tolerability, 
pharmacokinetic (PK), pharmacodynamic (PD), and immunogenicity of vedolizumab in healthy 
subjects and subjects with UC or CD. Please refer to the current edition of the Investigator’s 
Brochure (IB) for the most recent data for vedolizumab.
4.1.2.1
Nonclinical
Nonclinical in vitro and in vivo studies have been conducted with vedolizumab and its murine 
homologue, Act-1. Act-1 has demonstrated clinical and histomorphologic evidence of efficacy in 
an animal model of IBD (cotton-top tamarins). Extensive nonclinical evaluations of the 
cardiovascular, acute, local, subchronic, chronic, immunologic, and reproductive toxicity of 
vedolizumab in pharmacologically responsive species (New Zealand white rabbits and 
cynomolgus monkeys) have been conducted and support its clinical development. Nonclinical 
studies also show that vedolizumab does not antagonize #4∃1 integrin [24].
A single-dose local tolerance study was conducted to determine the local irritancy potential of 
vedolizumab SC when administered by SC injection to rabbits. Macroscopic and histological 
examinations of the injection sites indicated no findings of concern with the vehicle or formulated 
vedolizumab SC. 
4.1.2.2
Clinical Experience With Vedolizumab IV
Single- and multiple-dose PK of vedolizumab have been studied in healthy subjects and in subjects 
with moderately to severely active UC or CD and similar PK was observed. Vedolizumab exhibits 
CCI

target-mediated drug disposition; hence, its elimination is characterized by linear and nonlinear 
processes. Following IV infusion, vedolizumab serum concentrations generally fell in a 
biexponential fashion until approximately 1 to 10 µg/mL, with a linear total body clearance of 
approximately 0.157 L/day and a serum half-life of around 25 days. Thereafter, the serum 
concentrations fell in a nonlinear fashion. The volume of distribution for vedolizumab is 
approximately 5 L.
In subjects with moderately to severely active UC (C13006), vedolizumab IV 300 mg 
administered as an IV infusion at Weeks 0 and 2 (induction) followed by either Q4W or Q8W 
administration from Week 6 through Week 52 (maintenance) induced a statistically-significant 
increase in rates of clinical response at Week 6 and clinical remission at Week 52 (primary 
endpoint for the Induction Phase and Maintenance Phase, respectively) compared with placebo. 
The study also met important secondary endpoints, including durable clinical response, durable 
clinical remission, and mucosal healing at Weeks 6 and 52, and corticosteroid-free clinical 
remission at Week 52 (Table 4.a and Table 4.b). Given the significant morbidity associated with 
chronic corticosteroid treatment, the corticosteroid-sparing effects of vedolizumab provide an 
important benefit to patients with UC.

(a) This group includes those subjects who received vedolizumab at Weeks 0 and 2, and were randomized to receive 
placebo from Week 6 through Week 52.
(b) Corticosteroid-free remission was analyzed in subjects on oral corticosteroids at Baseline.
Vedolizumab has shown an acceptable safety profile based on an analysis of safety data from both 
completed and ongoing studies (see current edition of IB). In phase 1 and 2 clinical trials 
(7 completed phase 1 studies in healthy subjects and 8 completed phase 1b/2 studies in UC or CD 
subjects), there was no consistent evidence of any dose-toxicity relationships, and vedolizumab 
was well-tolerated. The majority of the safety data is from 3 well-controlled, phase 3 clinical 
studies that evaluated the safety of vedolizumab IV for up to 12 months in subjects with UC 
(Study C13006 [52 weeks]) or CD (Studies C13007 [52 weeks] and C13011 [10 weeks]). In 
addition, an interim safety assessment is available for an ongoing long-term open-label extension 
(OLE) study (C13008), in which subjects are administered vedolizumab IV Q4W.
In the pivotal phase 3 studies (C13006 and C13007), the most common (≥5% and at a higher 
incidence than placebo) adverse reactions in subjects administered vedolizumab IV were nausea, 
nasopharyngitis, upper respiratory tract infection, arthralgia, pyrexia, fatigue, headache, and 
cough. Most serious adverse events (SAEs) have been related to exacerbations or complications of 
the underlying UC or CD. For those infections that were reported more frequently in 
vedolizumab-treated subjects, the sites of these infections correlated with the known tissue 
distribution of MAdCAM-1 binding sites. Anal abscess, abdominal abscess, and gastroenteritis 
were the most frequently reported serious infections. Extraintestinal infections (bronchitis, 
pneumonia, urinary tract infection, sepsis) occurred at low frequency (<1%). A total of 4% of 
vedolizumab-treated subjects and 3% of placebo-treated subjects experienced an infusion-related 
reaction. In Studies C13006 and C13007, 10% of subjects were positive for anti-vedolizumab

antibodies (AVA) 16 weeks following the last dose of vedolizumab. Results from the clinical 
program to date do not suggest an increased risk for malignancy with vedolizumab treatment. 
Overall, the safety profile following long-term treatment with vedolizumab IV in Study C13008 is 
consistent with safety in the completed studies.
Concomitant use of corticosteroids and/or conventional immunomodulators did not appear to be 
associated with any increased rate of infections based on the comparative rates of infections in the 
phase 3 trials among subjects who had and had not received these medications. 
One death occurred in a vedolizumab-treated subject during Study C13006 and 5 deaths occurred 
during Study C13007, including 1 death in a placebo-treated subject. As of 19 May 2015, a total of 
26 deaths from multiple causes were reported in the vedolizumab clinical development program, 
including the ongoing long-term Study C13008. Twenty-five of the 26 subjects were randomized 
to the vedolizumab treatment group. Of these deaths, 14 occurred within 18 weeks of the last dose 
of study drug in phase 3 clinical studies and 11 occurred more than 18 weeks after the last dose of 
vedolizumab was administered. The causes of death varied and detailed information can be found 
in the current edition of the IB. 
Overall, vedolizumab was well tolerated in clinical studies.
4.1.2.3
Clinical Experience With Vedolizumab SC
The feasibility of administering the vedolizumab IV formulation by alternative dosing routes SC 
or intramuscular (IM) injection was explored in an open-label, single dose, parallel-group 
bioavailability study (C13010) in healthy male subjects. In this study, 42 subjects were enrolled 
and 14 subjects each received a single dose of 180 mg vedolizumab IV as IV infusion (over 
30 minutes), SC injections (2 × 1.5 mL × 60 mg/mL), or IM injections (2 × 1.5 mL × 60 mg/mL). 
Following SC administration, absorption of vedolizumab was gradual, achieving maximum 
concentration at 7 days post-injection (time to reach maximum serum concentration [tmax]). The 
maximum observed serum concentration (Cmax) following SC injection was approximately 1/3 of 
the Cmax following 30 minute IV infusion. There was no difference in the terminal elimination 
profile of the SC cohort compared to the IV cohort, indicating that the elimination of vedolizumab 
is not absorption rate-limited. The absolute bioavailability of vedolizumab was approximately 
75% for SC administration. Vedolizumab was well tolerated when administered at a dose of 
180 mg by SC injection. Five of the 14 subjects (36%) in the IV infusion cohort and 3 of the 
14 subjects (21%) in the SC cohort experienced a drug-related AE (assessed by the investigator). 
Most AEs were mild or moderate in severity. Three of the 14 subjects (21%) in the IV infusion 
cohort and 2 of the 14 subjects (14%) in the SC cohort in this study were AVA positive using the 
originally developed AVA assay that was used in the phase 3 studies with vedolizumab IV. While 
all 3 AVA positive subjects in the IV infusion cohort had neutralizing AVA, no neutralizing AVA 
was observed in the SC cohort.
The bioavailability and PK of vedolizumab following a single SC injection of vedolizumab SC at 
3 dose levels (54, 108, and 160 mg) relative to a single IV infusion of vedolizumab IV 300 mg was 
examined in a phase 1, open-label study (MLN0002SC-101). Forty-eight (24 Japanese and

24 non-Japanese) healthy, adult male and female subjects were randomized, A total of 12 subjects 
received a single dose of vedolizumab IV 300 mg and 36 subjects received a single dose of 
vedolizumab SC at 54, 108, or 160 mg (12 subjects per dose group).
The bioavailability following a single SC injection of vedolizumab SC was 75.1%, independent of 
the vedolizumab SC dose evaluated (54, 108, or 160 mg). Vedolizumab reached maximum serum 
concentrations around 1 week after a single SC injection. Vedolizumab was eliminated by both 
linear and nonlinear pathways following SC injection, with more rapid elimination with 
decreasing dose/concentration. Compared with non-Japanese subjects, Japanese subjects generally 
showed similar or slightly higher exposure; however, ethnicity did not have an impact on clearance 
or central volume of distribution based on the population PK analysis, likely due to the fact that 
weight was included as a covariate for various population PK parameters. Simulations further 
confirmed that vedolizumab SC at 108 mg every 2 weeks (Q2W) is expected to provide lower 
trough concentrations at steady state than vedolizumab IV 300 mg Q4W and similar steady-state 
exposures (average serum concentration at steady state [Cav,ss]) to that from the approved 
vedolizumab IV 300 mg Q8W maintenance regimen.
An electrochemiluminescence (ECL) assay has been developed to determine serum titers of AVA. 
This assay has improved drug tolerance as compared to the prior enzyme-linked immunosorbent 
assay (ELISA) method used in the vedolizumab clinical development program and, as a result, is 
more sensitive. Both assays were used in Study MLN0002SC-101; the ECL assay data were used 
in the analysis of PK and safety.
Overall, 75.0% (36/48) of subjects had treatment-emergent adverse events (TEAEs), and the 
percentage of subjects with a TEAE was identical in subjects who received vedolizumab SC 
compared with subjects who received vedolizumab IV. All TEAEs were considered by the 
investigator to be mild or moderate in intensity; no TEAEs of severe intensity were reported. The 
percentage of subjects with mild or moderate TEAEs was similar between subjects who received 
vedolizumab SC and vedolizumab IV; the percentages were also similar across the dose groups. 
No subjects had clinical laboratory test results, vital signs, or electrocardiogram (ECG) results that 
were reported as AEs. Two subjects had elevated bilirubin levels that met the predefined markedly 
abnormal value criteria; however, no subject had abnormal liver function test (LFT) results 
involving aspartate aminotransferase (AST) or alaninine aminotransferase (ALT).
Two AEs of special interest were reported: 1 subject in the vedolizumab SC 108 mg group 
experienced erythema at the injection site on the left thigh, and 1 subject in the vedolizumab SC

160 mg group experienced an injection site reaction. Both events occurred on Day 1, and were 
observed at the 30 minute postdose observation time point (a protocol-defined time point). In each 
case, the event resolved at the 1.5 hour postdose observation time point and was considered by the 
investigator to be mild in intensity and related to study drug. Both subjects recovered without any 
sequelae.
No SAEs, severe AEs, or deaths were reported in Study MLN00002SC-101. The observed AEs are 
consistent with the overall safety profile of vedolizumab.
4.2
Rationale for the Proposed Study
As IV infusion may not be convenient as long-term therapy for some patients, vedolizumab SC has 
been developed to enable injection by patients or their caregivers. 
This phase 3 study is designed to evaluate the efficacy, safety, PK, and immunogenicity of 
multiple injections of the new presentation, vedolizumab SC, as maintenance therapy in subjects 
with UC.
 
 
 Therefore, all nonclinical and 
clinical information from studies with vedolizumab IV is considered relevant. 
The vedolizumab exposure-efficacy relationship has been demonstrated in UC subjects in the 
phase 3 vedolizumab IV study (C13006), where higher serum vedolizumab concentrations were 
associated with higher efficacy (Source: Population PK Efficacy Report 2013). The proposed 
vedolizumab SC maintenance dosing regimen (108 mg Q2W) was selected to provide lower 
steady-state trough concentrations than the vedolizumab IV Q4W dosing regimen and similar 
Cavg steady-state exposures to that from the approved vedolizumab IV Q8W dosing regimen, and 
the safety and efficacy of the vedolizumab SC presentation are expected to be similar to those of 
vedolizumab IV, outside of expected local administration site events, such as injection-site 
reactions.
4.3
Benefit-Risk Assessment
The proposed study (MLN0002SC-3027) is designed to evaluate the efficacy and safety of 
vedolizumab SC as maintenance therapy in subjects with moderately to severely active UC who 
achieved clinical response following open-label vedolizumab IV therapy. Because IV infusion 
may not be convenient as long-term therapy, vedolizumab SC has been developed to ultimately 
enable injection by patients or their caregivers.

Therefore, the 
nonclinical and clinical information from studies with vedolizumab IV are considered relevant.
The study population in Study MLN0002SC-3027 is consistent with the approved vedolizumab IV 
label. The proposed vedolizumab SC maintenance dosing regimen (108 mg Q2W) was selected to 
provide similar steady-state exposure to that from the approved vedolizumab IV dosing regimen 
(300 mg Q8W). It is expected that similar steady-state exposure to vedolizumab will result in 
similar maintenance efficacy, independent of the dosing route or presentation. In addition, safety 
of the vedolizumab SC presentation is expected to be similar to that of vedolizumab IV due to 
similar exposure, outside of expected local administration site events, such as injection-site 
reactions. Results from a phase 1 study suggest that administration of vedolizumab SC (rather than 
IV) may result in higher immunogenicity; however, the clinical significance of these results is 
unclear, since this was a single-dose study in healthy subjects. The observed AEs with 
vedolizumab SC are consistent with the vedolizumab IV safety profile. 
Overall, vedolizumab has been well tolerated in clinical studies, including a phase 1 study of 
vedolizumab SC, and has a positive benefit-risk profile in the treatment of UC.

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is a pivotal, phase 3, multicenter, multinational, randomized, double-blind, double-dummy, 
placebo-controlled trial, including a vedolizumab IV reference arm, designed to evaluate the 
efficacy and safety of maintenance treatment with vedolizumab SC in adult subjects with 
moderately to severely active UC who achieved a clinical response at Week 6 with open-label 
therapy with 300 mg vedolizumab IV at Weeks 0 and 2. The study includes a vedolizumab IV 
reference arm to allow for within study descriptive comparisons on efficacy, safety, and 
immunogenicity between the two vedolizumab presentations.
Moderately to severely active UC is defined as a complete Mayo score of 6 to 12 points with 
endoscopic subscore of ≥2. Subjects that are either TNF-α antagonist naïve or with TNF-α 
antagonist failure will be included, ensuring that approximately 50% of subjects with TNF-α 
antagonist failure are enrolled. Subjects with previous use of TNF-α antagonist but not failed will 
NOT be enrolled.
The study includes a 4-week (28-day) Screening Period, a 6-week open-label vedolizumab IV 
Induction Phase, and a 46-week randomized, double-blind, double-dummy, placebo-controlled 
Maintenance Phase with vedolizumab SC or vedolizumab IV with a final visit at Week 52. All 
endoscopic assessments (ie, for disease severity at baseline and for clinical endpoints at the end of 
the Induction and Maintenance Phases) will be performed via central reading.
Eligible subjects, will be enrolled into the Induction Phase at Week 0, will receive open-label 
infusions of vedolizumab IV 300 mg at Weeks 0 and 2, and will be assessed for clinical response 
by full Mayo score (endoscopy score determined by central reading) at Week 6, as follows:

Subjects who achieve a clinical response at Week 6 will be randomized into the Maintenance 
Phase. Upon completion of the Week 52 assessment or upon early discontinuation due to 
treatment failure (ie, disease worsening or need for rescue medications) these subjects will be 
eligible to enter the OLE study. 

Subjects who do not achieve a clinical response at Week 6 will not be randomized in to the 
Maintenance Phase, and instead will receive a third infusion of vedolizumab IV 300 mg at 
Week 6. Subjects who achieve a clinical response at Week 14 (by partial Mayo score) will be 
eligible to enroll in the OLE study, while subjects who do not achieve clinical response will be 
discontinued. 
Subjects with clinical response at Week 6 will be randomized at a 2:1:1 ratio in the double-blind, 
double-dummy Maintenance Phase, where each treatment arm will receive both SC injections 
Q2W and IV infusions Q8W, beginning at Week 6 through Week 50, as follows:

Injections of vedolizumab SC 108 mg Q2W and placebo IV infusions every 8 weeks (Q8W) 
(N=94).

Infusions of vedolizumab IV 300 mg Q8W and placebo SC injections Q2W (N=47).


Placebo SC injections Q2W and placebo IV infusions Q8W (N=47).
Randomization will be stratified by:

Concomitant use of oral corticosteroids.

Clinical remission status at Week 6.

Previous TNF-α antagonists failure or concomitant immunomodulator (azathioprine or 
6-mercaptopurine) use.
At Week 6, subjects receiving oral corticosteroids who achieved a clinical response and are 
randomized into the Maintenance Phase will begin a corticosteroid tapering regimen.
After receiving training from the health care provider (HCP; investigator or designee) on the 
proper SC injection technique and how to manage hypersensitivity reactions potentially associated 
with the injection, subjects or their caregivers will inject vedolizumab SC/placebo SC under the 
supervision of the HCP during at least the Week 6 and 8 clinic visits, to ensure proper injection 
technique prior to home dosing and to allow for direct observation by the HCP of any potential 
hypersensitivity or injection-site reactions associated with SC injection. Subjects and caregivers 
may attend the clinic at Weeks 10 and 12 if further training is required. Subjects or their caregivers 
will also administer SC injections during the scheduled clinic visits at Weeks 14, 22, 30, 38, 46, 
and 50 under the supervision of the HCP to allow continued observation of injection technique and 
AEs; while all other scheduled SC injections should occur outside of the clinic. All IV infusions 
will be administered by a HCP during clinic visits at Weeks 6, 14, 22, 30, 38, and 46. HCPs will 
have appropriate monitoring and treatment for hypersensitivity reactions available for use 
following administration of study drug. Subjects who experience a severe hypersensitivity 
reaction associated with study drug administration will be discontinued from the study (see 
Section 7.4). 
Subjects and their caregivers will be instructed to inject SC doses into the thigh, abdomen, or upper 
arm, and to rotate the injection sites. Subjects and their caregivers will be instructed that the upper 
arm is to be used only when the caregiver administers the SC injection. Details on the training 
protocol and injection technique will be included in the appropriate Study Manual. For all SC 
dosing occurring outside of the clinic, subjects will receive a phone call from their HCP within 
24 hours prior to every injection to administer the PML subjective checklist and enquire about 
general health status and experience with prior injections. In accordance with the Risk Assessment 
and Management Plan for PML (RAMP), any positive PML subjective finding must be evaluated 
via the physician administered PML objective checklist prior to the subject receiving the 
respective dose (refer to RAMP Site Staff Brochure). Subjects will also receive a phone call from 
their HCP within 12 hours after the home injection at Weeks 10 and 12 to enquire about health
status and experience with injection unless they attended the clinic on these days. AEs reported by 
the subject will be handled in accordance with Section 10.0 of the protocol.
Subjects who do not participate in the OLE trial or are discontinued, will complete the 
End-of-Study Visits or Early Termination visit and then complete the Final Safety Visit 18 weeks

(ie, 5 vedolizumab half-lives) after the last dose of study drug. For subjects that are not in response 
at Week 14, early termination procedures will be performed at the Week 14 visit.
Additionally, subjects who do not participate in the OLE trial will be required to participate in a 
long-term follow-up (LTFU) safety-survey by telephone, 6 months after the last dose of study 
drug.

6.2
Justification for Study Design, Dose, and Endpoints
This phase 3 study is designed to evaluate the efficacy, safety, PK, and immunogenicity of 
multiple injections of the new presentation, vedolizumab SC, as maintenance therapy in subjects 
with UC. The proposed vedolizumab SC maintenance dosing regimen (108 mg Q2W) was 
selected to provide similar steady-state exposures to that from the approved vedolizumab IV 
dosing regimen (300 mg Q8W), and the safety and efficacy of the vedolizumab SC presentation is 
expected to be similar to that of vedolizumab IV, outside of expected local administration site 
events, such as injection-site reactions. 
The study design allows for independent assessments of vedolizumab SC efficacy as maintenance 
therapy in subjects who responded to vedolizumab IV by comparing the active vedolizumab SC 
therapy group to the placebo group during the Maintenance Phase. It also permits double-blind, 
placebo-controlled comparisons of safety parameters during the Maintenance Phase. Additional 
measures will be taken to collect safety parameters beyond the 52-week duration of the trial, where 
subjects who do not enroll in OLE will have a Final Safety Visit conducted 18 weeks after the 
subject’s last dose of study drug, and additional safety information will be collected by telephone 
using a LTFU survey at 6 months after the last study dose (for both SC and IV dosing).
Consistent with the currently approved vedolizumab IV label, subjects who do not achieve a 
clinical response at Week 6 and are not randomized into the Maintenance Phase will receive an 
additional vedolizumab IV infusion at Week 6 and will be eligible to participate in the OLE study 
if clinical response is achieved at Week 14.
The entry criteria ensure that subjects who are appropriate for treatment with biologic agents, as 
assessed by severity of disease and failure of one or more standard therapies (ie, corticosteroids, 
immunomodulators, or TNF-α antagonists), will be enrolled into the study. Entry criteria will also 
exclude subjects who might not benefit from drug or who might be at risk for treatment toxicities. 
Additional measures to ensure the safety of enrolled subjects include protocol-mandated criteria 
for withdrawal from the study of subjects who experience worsening of disease or require rescue 
medication (ie, any new medication or any increase in dose of a baseline medication required to 
treat new or unresolved UC symptoms, other than antidiarrheals for control of chronic diarrhea). 
Thus, subjects who may be treated with placebo (inactive treatment) between Weeks 6 and 52 will 
be withdrawn from the study if they experience treatment failure (ie, disease worsening, need for 
rescue medications), but may be eligible to enroll in the OLE study.
At Week 6, subjects receiving oral corticosteroids who achieve clinical response must begin a 
corticosteroid tapering regimen as described in Section 7.3.1.1. Subjects are allowed to continue 
background therapy such as 5-ASAs or immunomodulators, as indicated in the Permitted 
Medications and Treatments in Section 7.3.1.

The primary efficacy endpoint of this study is clinical remission at Week 52 in subjects who 
receive vedolizumab SC maintenance therapy compared to placebo SC therapy. This primary 
efficacy endpoint is generally accepted as the standard indicator of disease activity in UC subjects. 
Exposure-efficacy analyses were conducted using either observed or population model predicted 
vedolizumab concentrations from the phase 3 vedolizumab IV studies. There was an apparent 
exposure-efficacy relationship in subjects with UC for both the Induction and Maintenance 
Phases, where higher vedolizumab concentrations were associated with higher efficacy. Based on 
the exposure-efficacy relationship for vedolizumab IV, the vedolizumab SC dosing regimen was 
selected to provide lower trough concentrations than vedolizumab IV Q4W and similar exposure 
to that from the approved vedolizumab IV Q8W regimen during the Maintenance Phase. It is 
expected that similar exposure to vedolizumab will result in similar efficacy and safety during 
maintenance, independent of the dosing route or formulation.
In addition to efficacy and safety evaluations, the multiple dose PK and immunogenicity of 
vedolizumab SC in subjects during the Maintenance Phase will be evaluated in this study. Given 
the long half-life of vedolizumab (approximately 25 days), blood samples will be collected up to 
18 weeks (>5 half-lives) after the last dose of study drug to assess the PK of vedolizumab.
During the Maintenance Phase of this study, vedolizumab SC or placebo SC injections will be 
administered by the subjects or their caregivers both at clinic visits (Weeks 6, 8, 14, 22, 30, 38, 46 
and 50 under HCP supervision) and outside of the clinic, while vedolizumab IV and placebo IV 
infusions will be administered by HCP only during clinic visits (Weeks 6, 14, 22, 30, 38, and 46). 
HCPs will train the subjects (and their caregivers) on the adequate technique to prepare and inject 
study drug during at least at the Week 6 and 8 office visits, and will also provide instructions on 
adequate storage of vedolizumab SC, disposal of used prefilled syringe, hypersensitivity reaction 
management, and contact information for any questions on vedolizumab SC use. Details on the 
training protocol and injection technique will be included in the appropriate Study Manual. 
Pharmacogenomic analysis may be conducted to evaluate the contribution of genetic variance on 
drug response, eg, its efficacy and safety. Participation of study subjects in pharmacogenomic 
sample collection is optional (Section 9.1.16). As pharmacogenomics is an evolving science, 
currently many genes and their function are not yet fully understood. Future data may suggest a 
role of some of these genes in drug response and disease, which may lead to additional 
hypothesis-generating exploratory research on stored samples.
If future analysis is required, the sponsor will create a research protocol for pharmacogenomics 
investigations and the research protocol will require prior approval by an institutional review 
board (IRB) prior to implementation (Japan only).

Excluded Medications and Treatments
The following medications are excluded from use during the study: 

Any treatment for UC other than those listed in Section 7.3.1 (either approved or 
investigational).

All live vaccines from 30 days prior to screening to at least 6 months after the last dose of study 
drug. 

Either approved or investigational biological agents for the treatment of non-IBD conditions, 
other than localized injections (eg, intraocular injections for wet macular degeneration). 

Chronic nonsteroidal anti-inflammatory drug (NSAID) use. (Note: occasional use of NSAIDs 
and acetaminophen for headache, arthritis, myalgias, menstrual cramps, etc. and daily use of 
baby or low-dose [81-162.5 mg] aspirin for cardiovascular prophylaxis are permitted.) 

Leukocytapheresis (LCAP; white blood apheresis) or granulocytapheresis (GCAP) (Japan 
only).

Subjects must be instructed not to take any medications, including over-the-counter products, 
without first consulting with the investigator.
7.3.1
Permitted Medications and Treatments 

The subject may be receiving a therapeutic dose of the following drugs: 
–
Oral 5-ASAs compounds provided that the dose has been stable for the 2 weeks 
immediately prior to first dose of study drug. The dose for these medications should remain 
stable throughout the study.
–
Oral corticosteroid therapy (prednisone at a stable dose ≤30 mg/day, budesonide at a stable 
dose ≤9 mg/day, or equivalent steroid) provided that the dose has been stable for the 
4 weeks immediately prior to first dose of study drug if corticosteroids have just been 
initiated, or for the 2 weeks immediately prior to first dose of study drug if corticosteroids 
are being tapered. Corticosteroid doses should remain stable until the subject meets the 
criteria for initiating a corticosteroid tapering regimen (see Section 7.3.1.1).
–
Probiotics (eg, Culturelle, Saccharomyces boulardii) provided that the dose has been stable 
for the 2 weeks immediately prior to first dose of study drug. The dose for these 
medications should remain stable throughout the study.

Vedolizumab SC
Study No. MLN0002SC-3027
Page 45 of 109
Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
–
Antidiarrheals (eg, loperamide, diphenoxylate with atropine) for control of chronic 
diarrhea; stable doses are encouraged.
–
Azathioprine or 6-mercaptopurine, provided that the dose has been stable for the 8 weeks 
immediately prior to first dose of study drug. Dose(s) should remain stable, unless the 
medication is discontinued due to a toxicity related to the medication. Even if the toxicity 
resolves, azathioprine or 6-mercaptopurine will not be re-started.

For immunosuppressives, oral 5-ASAs, probiotics and antibiotics for UC, dose reduction or 
discontinuation per label will be allowed only due to adverse reactions. For oral corticosteroid, 
as per the tapering schedule (see Section 7.3.1.1).

Need for Rescue Medications: In this study, any new medication or any increase in dose of a 
baseline medication required to treat new or unresolved UC symptoms (other than 
antidiarrheals for control of chronic diarrhea) is considered a rescue medication. An increase in 
corticosteroid dose back to baseline for subjects undergoing corticosteroid tapering within the 
guidelines presented in Section 7.3.1.1 is not considered rescue medication. Administration of 
rescue medications, approved or investigational, constitutes treatment failure. Rescue 
medications should not be withheld if, in the opinion of the investigator, failure to prescribe 
them would compromise subject safety.
7.3.1.1
Oral Corticosteroid Dosing and Tapering 

At Week 6, subjects receiving oral corticosteroids who achieved clinical response will begin a
corticosteroid tapering regimen. The tapering schedule is as follows: 
–
For prednisone at doses >10 mg/day (or equivalent), the dose should be reduced at a rate of 
5 mg/week until a 10 mg/day dose is reached. 
–
For prednisone at doses ≤10 mg/day (or equivalent) or once a 10 mg/day dose (or 
equivalent) is achieved by tapering, the dose should be reduced at a rate of 2.5 mg/week 
until discontinuation.
For subjects who cannot tolerate the corticosteroid taper without recurrence of clinical symptoms, 
corticosteroids may be increased up to the original dose at the start of induction therapy (should 
not exceed baseline dose). In such cases, the tapering regimen above must be reinitiated within 
2 weeks. Subjects who consistently cannot be tapered should be withdrawn from the study 
according to Section 7.4.
Currently, there is no evidence to support the routine prophylactic administration of premedication 
(eg, antihistamines, corticosteroids) to subjects receiving vedolizumab; hence, such premedication 
is unlikely to be necessary or beneficial. At the discretion of the investigator, however, subjects 
may be administered premedication prior to any study drug administration. Corticosteroids, if 
given as a premedication, should be limited to the day of administration.

7.4
Criteria for Discontinuation or Withdrawal of a Subject
The primary reason for discontinuation or withdrawal of the subject from the study or study 
medication should be recorded in the electronic case report form (eCRF) using the following 
categories. For screen failure subjects, refer to Section 9.1.22.
1. Pretreatment event (PTE) or AE. The subject has experienced a PTE or AE that requires early 
termination because continued participation imposes an unacceptable risk to the subject’s 
health or the subject is unwilling to continue because of the PTE or AE.

LFT Abnormalities.
Study medication should be discontinued immediately with appropriate clinical follow-up 
(including repeat laboratory tests, until a subject’s laboratory profile has returned to 
normal/baseline status, see Section 9.1.9), if the following circumstances occur at any time 
during study medication treatment:
–
ALT or AST >8 × ULN, or
–
ALT or AST >5 × ULN and persists for more than 2 weeks, or
–
ALT or AST >3 × ULN in conjunction with elevated total bilirubin >2 × ULN or 
international normalized ratio (INR) >1.5, or
–
ALT or AST >3 × ULN with appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash and/or eosinophilia (>5%).
2. Significant protocol deviation. The discovery after the first dose of study medication that the 
subject failed to meet protocol entry criteria or did not adhere to protocol requirements, and 
continued participation poses an unacceptable risk to the subject’s health.
3. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. Three attempts to contact the subject must be documented (ie, 2 attempts 
by phone and 1 attempt by registered letter).
4. Voluntary withdrawal. The subject (or subject’s legally acceptable representative) wishes to 
withdraw from the study. The reason for withdrawal, if provided, should be recorded in the 
eCRF.
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (ie, withdrawal due to an 
AE or lack of efficacy should not be recorded in the “voluntary withdrawal” category). 
5. Study termination. The sponsor, IRB, IEC, or regulatory agency terminates the study.
6. Pregnancy. The subject is found to be pregnant. 
Note: If the subject is found to be pregnant, the subject must be withdrawn immediately. The 
procedure is described in Section 9.1.11.

7. Lack of efficacy. The subject should be discontinued from the study if the following criteria 
apply:

Week 14 discontinuation in subjects not randomized to the Maintenance Phase, due to not 
achieving a clinical response at Week 6 who also did not achieve a clinical response at 
Week 14 after having received a third vedolizumab IV infusions at Week 6.

Treatment failure during the Maintenance Phase, defined as disease worsening (as defined 
in Section 3.5), need for rescue medications (as defined in Section 7.3.1), or need for 
surgical intervention for treatment of UC.

Leukopenia or Lymphopenia: WBC and lymphocyte counts will be monitored for all subjects. 
Azathioprine, or 6-mercaptopurine, if applicable, should be discontinued and the dose of study 
drug held for an absolute lymphocyte count <0.5 × 109/L at any point in the study. The absolute 
lymphocyte count must be repeated at appropriate intervals as determined by the investigator. 
The next dose of study drug can be administered only if the absolute lymphocyte count is ≥0.5 
× 109/L. If the absolute lymphocyte count remains <0.5 × 109/L, study drug should be 
discontinued and the subject withdrawn from the study.
8. Other: 
Note: The specific reasons should be recorded in the “specify” field of the eCRF.
Subjects who discontinue due to lack of efficacy are permitted to enroll in the OLE study 
(MLN0002SC-3030) according to the criteria in Table 7.a.

Procedures for Discontinuation or Withdrawal of a Subject
The investigator may discontinue a subject’s study participation at any time during the study when 
the subject meets the study termination criteria described in Section 7.4. In addition, a subject may 
discontinue his or her participation without giving a reason at any time during the study. Should a
subject’s participation be discontinued, the primary criterion for termination must be recorded by 
the investigator. In addition, efforts should be made to perform all procedures scheduled for the ET 
Visit, Final Safety Visit, and the LTFU survey. Discontinued or withdrawn subjects will not be 
replaced.

Overdose
An overdose is defined as a known deliberate or accidental administration of investigational drug, 
to or by a study subject, at a dose above that which is assigned to the individual subject according 
to the study protocol.
All cases of overdose (with or without associated AEs) will be documented on an Overdose page 
of the eCRF, in order to capture this important safety information consistently in the database. 
Cases of overdose without manifested signs or symptoms are not considered AEs. AEs associated 
with an overdose will be documented on AE eCRF(s) according to Section 10.0, Pretreatment 
Events, Adverse Events, and Product Complaints.
SAEs associated with overdose should be reported according to the procedure outlined in 
Section 10.2.2, Collection and Reporting of SAEs.
In the event of drug overdose, the subject should be treated symptomatically. 
8.2
Investigational Drug Assignment and Dispensing Procedures
Subjects will be assigned to receive treatment according to the schedule allocated to each study 
site.
The investigator or investigator’s designee will access the interactive web response system 
(IWRS) at Screening to register a subject and obtain a subject identification number to identify the 
subject throughout the study. The investigator or the investigator’s designee will utilize the IWRS 
to enroll the subject into the study. The medication identification (ID) number of the 
investigational drug to be dispensed will then be provided by the IWRS as well as at subsequent 
visits. If sponsor-supplied drug is lost or damaged, the site can request a replacement from IWRS. 
Refer to the appropriate study manual provided separately for additional information. 
For IV infusion, subjects will receive a 300 mg dose of vedolizumab IV infusion over 
approximately 30 minutes. Longer infusion times of up to 60 minutes may be used based on study 
observations. Vedolizumab IV should be administered by a HCP prepared to manage 

Vedolizumab SC

hypersensitivity reactions including anaphylaxis, if they occur. Appropriate monitoring and 
medical support measures should be available for immediate use. Subjects should be observed for 
2 hours following the first 2 infusions, at a minimum, and one hour after each subsequent infusion
in a room where appropriate treatment for infusion-related reactions is available. The subject 
should be considered clinically stable by the investigator or designee prior to discharge.
For SC injection, the recommended sites are the abdomen (except for the 2-inch area around the 
navel), the outer area of the upper arms, or the front of the thighs. The upper arm injection site 
should be used only by caregivers administering the injection. The injection site should be changed 
for consecutive injections. Each new injection should be given at least 1 inch from a site used 
before.
During clinic visits, SC injections should be administered by the subject (or caregiver) under the 
supervision of a HCP prepared to manage hypersensitivity reactions including anaphylaxis, if they 
occur. Appropriate monitoring and medical support measures should be available for immediate 
use. Subjects should be observed during the SC administration and for one hour following 
completion of the administration.
Study medication storage, disposal and directions for use for the subject self-injections will be 
described in information provided to the subject.
For further investigational drug and dispensing information, please refer to the pharmacy and/or 
the appropriate study manual.
8.3
Randomization Code Creation and Storage
After receiving open-label infusions of vedolizumab IV 300 mg at Weeks 0 and 2, subjects will be 
assessed for clinical response (as determined by a central reader) at Week 6. 
Subjects with clinical response at Week 6 will be randomized at a 2:1:1 ratio to receive the 
following, beginning at Week 6 through Week 50:

Injections of active vedolizumab SC 108 mg Q2W and placebo IV infusions Q8W (N=94).

Infusions of active vedolizumab IV 300 mg Q8W and placebo SC injections Q2W (N=47).

Placebo SC injections Q2W and placebo IV infusions Q8W (N=47).
Randomization will be stratified by:

Concomitant use of oral corticosteroids.

Clinical remission status at Week 6.

Previous TNF-α antagonists failure or concomitant immunomodulator (azathioprine, 
6-mercaptopurine) use.
Randomization personnel of the sponsor or designee will generate the randomization schedule 
prior to the start of the study. An IWRS system will be used for subject randomization. All 

Vedolizumab SC

randomization information will be stored in a secured area, accessible only by authorized 
personnel.
8.4
Investigational Drug Blind Maintenance and Unblinding
The investigational drug blind will be maintained using the IWRS. In addition, in order to maintain 
the blind, all study site personnel except the investigational pharmacist or pharmacy designee will 
be blinded to the treatment assignments for the duration of the study.
The investigational drug blind may be broken by the investigator if information concerning the 
investigational drug is essential for the medical treatment of the subject. The medical monitor must 
be informed of the unblinding at the earliest possible opportunity. In nonurgent cases, the medical 
monitor must be contacted before the subject is unblinded.
For unblinding a subject, the investigational drug blind can be obtained by the investigator, by 
accessing the IWRS. The sponsor must be notified as soon as possible if the investigational drug 
blind is broken. The date, time, and reason the blind is broken must be recorded in the source 
documents and eCRF as appropriate.
8.5
Accountability and Destruction of Sponsor-Supplied Drugs
Drug supplies will be counted and reconciled at the site before being returned to the sponsor or 
designee.
The blinded investigator or blinded designee and delegated unblinded pharmacy staff, must ensure 
that the sponsor-supplied drug is used in accordance with the protocol and is dispensed only to 
subjects enrolled in the study. To document appropriate use of sponsor-supplied drug, 
[vedolizumab IV vials and vedolizumab SC/placebo SC pre-filled syringes], the appropriate 
blinded or unblinded person must maintain respective records of all sponsor-supplied drug 
delivery to the site, site inventory, dispensation, and use, by each subject, and return to the sponsor 
or designee.
Records of the subject number, the date study drug was dispensed, and the study drug/cohort 
assignment will be maintained by the unblinded pharmacist.
Upon receipt of sponsor-supplied drug, the appropriate unblinded pharmacist must verify the 
contents of the shipments against the packing list. The verifier should ensure that the quantity is 
correct, and the medication is in good condition. If quantity and conditions are acceptable, they 
should acknowledge the receipt of the shipment (by signing the bottom half of the packing list and 
faxing per instructions provided on the form/ or by recording in IWRS). If there are any 
discrepancies between the packing list and the actual product received, Takeda must be contacted 
to resolve the issue. The packing list should be filed in the investigator’s essential document file 
(unblinded pharmacy file).

The unblinded pharmacist must maintain 100% accountability for all sponsor-supplied drugs 
received and dispensed. Proper drug accountability includes, but is not limited to:

Continuously monitoring expiration dates if expiry date is provided to the investigator or 
designee.

Frequently verifying that actual inventory matches documented inventory.

Verifying that the log is completed for the (drug lot/medication ID/job number) used to prepare 
each dose.

Verifying that all containers used/assigned are documented accurately on the log.

Verifying that required fields are completed accurately and legibly.
If any dispensing errors or discrepancies are discovered, the sponsor must be notified immediately.
The IWRS will include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.
The unblinded pharmacist must record the current inventory of all sponsor-supplied drugs on a 
sponsor-approved drug accountability log. The following information will be recorded at a 
minimum: protocol number and title, name of investigator, site identifier and number, description 
of sponsor-supplied drugs, date and amount dispensed including initials, date and amount returned 
to the site by the subject, and the initials, seal, or signature of the person dispensing the drug. The 
log should include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.
All study drug that was not returned to the site by a subject must be investigated by the site and 
appropriately documented in the subject’s medical records and on the drug accountability log.
Prior to site closure or at appropriate intervals, an unblinded representative from the sponsor or its 
designee will perform sponsor-supplied drug accountability and reconciliation before 
sponsor-supplied drugs are returned to the sponsor or its designee for destruction. The designated 
unblinded pharmacist will retain a copy of the documentation regarding sponsor-supplied drug 
accountability, return, and/or destruction, and originals will be sent to the sponsor or designee.

STUDY PLAN
9.1
Study Procedures
The following sections describe the study procedures and data to be collected. For each procedure, 
subjects are to be assessed by the same investigator or site personnel whenever possible. The 
Schedule of Study Procedures is located in Appendix A.
9.1.1
Informed Consent Procedure
The requirements of the informed consent are described in Section 15.2.
Informed consent must be obtained prior to the subject entering into the study, and before any 
protocol-directed procedures are performed.
A unique subject identification number (subject number) will be assigned by IWRS to each subject 
at the time of screening; this subject number will be used throughout the study.
9.1.1.1
Pharmacogenomic Informed Consent Procedure
A separate informed consent form pertaining to the storage of samples must be obtained prior to 
collecting blood samples and tissue samples for pharmacogenomic research for this study. The 
provision of consent to collect and analyze the pharmacogenomic samples is optional and 
independent of consent to the other aspects of the study.
9.1.2
Demographics, Medical History, and Medication History Procedure
Demographic information to be obtained will include age or date of birth (depending on local 
regulations), sex, Hispanic ethnicity (as applicable, US only), race as described by the subject and 
smoking status of the subject at screening. 
Medical history to be obtained will include determining whether the subject has any significant 
conditions or diseases relevant to the disease under study that stopped at or prior to signing of 
informed consent. Ongoing conditions are considered concurrent medical conditions (see 
Section 9.1.8).
Medication history information to be obtained includes any medication relevant to eligibility 
criteria stopped at or within 30 days prior to signing of informed consent.
9.1.3
Physical Examination Procedure
A baseline physical examination (defined as the assessment prior to first dose of investigational 
drug) will consist of the following body systems: (1) eyes; (2) ears, nose, throat; (3) cardiovascular 
system; (4) respiratory system; (5) gastrointestinal system; (6) dermatologic system; 
(7) extremities; (8) musculoskeletal system; (9) nervous system; (10) lymph nodes; (11) other. All 
subsequent physical examinations should assess clinically significant changes from the assessment 
prior to first dose examination.

9.1.4
Weight and Height 
A subject should have weight and height measured while wearing indoor clothing and with shoes 
off. The Takeda standard for collecting height is centimeters without decimal places and for 
weight it is kilograms (kg) with 1 decimal place. 
9.1.5
Vital Sign Procedure
Vital signs will include body temperature, respiratory rate, blood pressure (sitting), and pulse 
(bpm).
When vital signs are scheduled at the same time as blood draws, the blood draw will take priority 
and vital signs will be obtained within 0.5 hour before the scheduled blood draw. 
On dosing days, vital signs are taken predose. 
9.1.6
Primary Efficacy Measurement 
Primary and secondary efficacy assessments during the Maintenance Phase will be based on Mayo 
scores. A complete Mayo score will be obtained within 10 days prior to enrollment, using subject 
diary entries within the 10 days prior to enrollment and flexible sigmoidoscopy results obtained 
during the Screening Period; this assessment will be the baseline complete Mayo score for disease 
activity assessment. Sigmoidoscopy will be done at Week 6 and Week 52 (or ET Visit), and a 
complete Mayo score will be calculated for these visits for endpoints assessment. All endoscopies 
(Week 0, 6, and 52) will be centrally read. Additional information regarding the sigmoidoscopy 
requirements and central reader assessments can be found in the appropriate Study Manual.
The baseline complete Mayo score will be used for the comparison with the Week 6 complete 
Mayo score to determine response and remission at Week 6 and with the Week 52 complete Mayo 
score to determine response and remission at Week 52.
The Week 0, 6, and 52 complete Mayo score will be calculated by the investigator or designee and 
recorded in the subject’s source documents, with the endoscopic component subscore being 
provided by the central reader. The Week 6 assessment will determine whether the subject 
achieved clinical response at Week 6, and therefore, determine eligibility for randomization in to 
the Maintenance Phase. 
A partial Mayo score will be derived at the visits at which endoscopy will not performed. 
Refer to Appendix F for information on the Mayo scoring system.
9.1.6.1
Diary Completion and Review
Diary entries will be made daily by subjects from screening to end of study, and will be used for 
Mayo score calculation. At screening, subjects will be instructed on how to appropriately complete 
the daily diary. The symptoms of UC must be recorded throughout the study, including the 
Screening Period. Diary entries will be made daily by the subject through a validated electronic

CONFIDENTIAL
system. In addition to the subject reported Mayo subscore components, subjects will use the 
validated electronic system to enter daily absolute stool frequency.
Because the flexible sigmoidoscopy preparation can interfere with the assessment of other clinical
parameters, diary entries used to calculate the complete Mayo score should not be taken from the 
day before (the preparation day), the day of, and the day after the flexible sigmoidoscopy is 
performed.
Entries should be reviewed and monitored by the study staff (see the appropriate Study Manual). 
9.1.7
Documentation of Concomitant Medications
Concomitant medication is any drug given in addition to the study medication. These may be 
prescribed by a physician or obtained by the subject over the counter. Concomitant medication is 
not provided by Takeda. At each study visit, subjects will be asked whether they have taken any 
medication other than the study medication (used from signing of informed consent through the 
end of the study), and all medication including vitamin supplements, over-the-counter 
medications, and oral herbal preparations, must be recorded in the eCRF. Medications used 
specifically for premedication purposes will be collected separately in the eCRF.
9.1.8
Documentation of Concurrent Medical Conditions
Concurrent medical conditions are those significant ongoing conditions or diseases that are present 
at signing of informed consent. This includes clinically significant laboratory, ECG, or physical 
examination abnormalities noted at screening or baseline examination. The condition (ie, 
diagnosis) should be described.
9.1.9
Procedures for Clinical Laboratory Samples
All samples will be collected in accordance with acceptable laboratory procedures at the time 
points specified in the schedule of events. The maximum volume of blood at any single visit is 
approximately 22 mL, and the approximate total volume of blood for the study is 230 mL. Details 
of these procedures and required safety monitoring will be given in the laboratory manual.
Clinical laboratory tests to be performed in this study are summarized in Table 9.a. Refer to the 
Schedule of Events in Appendix A for timing of all assessments. See Laboratory Manual for 
testing regimen.

If the ALT or AST remains elevated >3 ×ULN on these 2 consecutive occasions the investigator 
must contact the Medical Monitor for consideration of additional testing, close monitoring, 
possible discontinuation of study medication, discussion of the relevant subject details and 
possible alternative etiologies. The abnormality should be recorded as an AE (please refer to 
Section 10.2.3 Reporting of Abnormal Liver Function Tests for reporting requirements).
9.1.10 Contraception and Pregnancy Avoidance Procedure
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study medication, nonsterilized** male subjects who are sexually active with a female 
partner of childbearing potential* must use barrier contraception (eg, condom with spermicidal 
cream or jelly). In addition, they must be advised not to donate sperm during this period.
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study medication, female subjects of childbearing potential* who are sexually active with a 
nonsterilized male partner** must use adequate contraception. In addition they must be advised 
not to donate ova during this period.
*Females NOT of childbearing potential are defined as those who have been surgically sterilized 
(hysterectomy, bilateral oophorectomy or tubal ligation) or who are postmenopausal (eg, defined 
as at least 1 year since last regular menses with an FSH >40 IU/L or at least 5 years since last 
regular menses, confirmed before any study medication is implemented).
**Sterilized males should be at least 1 year postvasectomy and have confirmed that they have 
obtained documentation of the absence of sperm in the ejaculate.
An acceptable method of contraception is defined as one that has no higher than a 1% failure rate. 
In this study, where medications and devices containing hormones are included, the only 
acceptable methods of contraception will be:
Barrier methods (each time the 
subject has intercourse):
Intrauterine devices 
(IUDs):
Hormonal contraceptives:

Male condom PLUS spermicide.

Cap (plus spermicidal cream or 
jelly) PLUS male condom and 
spermicide.

Diaphragm (plus spermicidal 
cream or jelly) PLUS male 
condom and spermicide.

Copper T PLUS condom 
or spermicide.

Progesterone T PLUS 
condom or spermicide.

Implants.

Hormone shot/injection.

Combined pill.

Minipill.

Patch.

Vaginal ring PLUS male 
condom and spermicide.
Subjects will be provided with information on acceptable methods of contraception as part of the 
subject informed consent process and will be asked to sign a consent form stating that they

understand the requirements for avoidance of pregnancy, donation of ova, and sperm donation 
during the course of the study.
During the course of the study, subjects will receive continued guidance with respect to the 
avoidance of pregnancy as part of the study procedures (Appendix A). 
All female subjects of child bearing potential will have a serum pregnancy test during screening 
and at Week 52 (or ET Visit) and Week 68 (or Final Safety Visit). A urine pregnancy test will be 
completed for all females of child bearing potential on a monthly basis prior to administration of 
study drug.
9.1.11 Pregnancy
If any subject is found to be pregnant during the study she should be withdrawn and any 
sponsor-supplied drug should be immediately discontinued and returned to the study site. In 
addition, any pregnancies in the partner of a male subject during the study or for 18 weeks after the 
last dose, should also be recorded following authorization from the subject’s partner.
If the pregnancy occurs during administration of active study medication or within 18 weeks of the 
last dose of active study medication, the pregnancy should be reported immediately, using a 
pregnancy notification form, to the contact listed in Section 1.0.
Should the pregnancy occur during or after administration of blinded drug, the investigator must 
inform the subject of their right to receive treatment information. If the subject chooses to receive 
unblinded treatment information, the individual blind should be broken by the investigator.
Subjects randomized to placebo need not be followed.
If the female subject, or female partner of a male subject, agrees to the primary care physician 
being informed, the investigator should notify the primary care physician that the subject was 
participating in a clinical study at the time the subject/female partner of the subject became 
pregnant and provide details of treatment the subject received.
All pregnancies from subjects on active study drug will be followed up to final outcome, using the 
pregnancy form. The outcome, including any premature termination, must be reported to the 
sponsor. An evaluation after the birth of the child will also be conducted.
9.1.12 ECG Procedure 
A standard 12-lead ECG will be recorded. The investigator (or a qualified observer at the 
investigational site) will interpret the ECG using 1 of the following categories: within normal 
limits, abnormal but not clinically significant, or abnormal and clinically significant.
Any findings from ECGs collected after study drug administration at Week 0 will be captured as 
AEs if, in the opinion of the investigator, there has been a clinically significant change from 
baseline.

Subjects will be supine and will have rested for 5 or more minutes before any ECG is recorded. 
Tracings will include subject number and initials and the date and time of recording and all other 
subject identifiers will be removed or obscured.
9.1.13
Histological Sample Collection
At each endoscopy (Week 0, 6, and 52/ET) tissue biopsies will be performed and tissue specimens 
be harvested and stored for future histological analyses.
All tissue specimens will be reviewed by independent central review. Additional information 
regarding the central reader assessments and collection and preparation of tissue samples can be 
found in the appropriate Study Manual.
9.1.14
Immunogenicity Sample Collection 
Blood specimens for the assessment of AVA will be collected as shown in the schedule of events 
(Appendix A). A sample will be assessed for neutralizing AVA if AVA is detected. 
Serum titers of AVA will be determined using a validated assay. Neutralizing AVA will be 
determined using a validated assay. 
Please refer to the appropriate Study Manual for information on sample collection and preparation.
9.1.15
Pharmacokinetic Sample Collection
Blood specimens for the determination of the serum concentration of vedolizumab will be 
collected predose (within 30 minutes of dosing) and/or as shown in the schedule of events. Serum 
concentrations of vedolizumab will be determined using a validated sandwich ELISA. All samples 
will be analyzed regardless of the treatment groups.
9.1.16
Pharmacogenomic Sample Collection
When sampling of whole blood or mucosal tissue for pharmacogenomic analysis occurs, every 
subject must sign an additional informed consent/be consented in order to participate in the study.
Two whole blood samples (3 mL per sample) for deoxyribonucleic acid (DNA) isolation will be 
collected before dosing on Day 1 from each subject in the study. If DNA samples are not obtained 
on Day 1, they may be collected at any point in the study.
Two whole blood ribonucleic acid (RNA) samples (2.5 mL per sample) will be collected into 
PAXgeneTM tubes before dosing on Day 1.
If separately consented to by the subject, a small piece of tissue from the colonic tissue sample 
harvested for histological analysis (during the Screening, and Week 6, and 52 endoscopy) will be 
saved and stored for possible exploratory investigation to look for changes in mRNA expression 
patterns associated with disease or response to therapy.

Information regarding the collection and preparation of tissue samples for pharmacogenomic 
analysis can be found in the appropriate Study Manual. DNA forms the basis for the genes that

make the body produce proteins such as enzymes, drug transporters or drug targets. RNA has 
multiple vital roles in the coding, decoding, regulation, expression of genes, and sensing and
communicating responses to cellular signals. Both DNA and RNA samples may be evaluated 
for the genetic and expressional contribution how the drug is broken down, or how the drug 
affects the body. This is called a “Pharmacogenomics research study.” 
Specific purposes of this study include:

Identifying genetic reasons why certain people respond differently to vedolizumab.

Finding out more information about how vedolizumab works.

Generating information needed for research, development, and regulatory approval of tests to 
predict response to vedolizumab.

Identifying variations in genes related to the biological target of vedolizumab.
This information may be used, for example, to develop a better understanding of the safety and 
efficacy of vedolizumab and other study medications, and for improving the efficiency, design and 
study methods of future research studies.
If necessary and feasible, a second aliquot of blood may be taken if isolation of DNA from the first 
sample was not successful or possible. Please refer to the appropriate Study Manual for 
information on sample collection and preparation.
The samples will be stored for no longer than 15 years after completion of the study. No samples 
will be stored for longer than permitted by the applicable law and samples will be destroyed upon 
notification from Takeda. “Stored samples” are defined as samples that are key-coded (the 
samples are stripped of all personal identifying information but a key links the samples to the 
clinical data collected from the sample donor) and are used in the analysis of investigational drug 
or related drugs.
Future analysis of the stored pharmacogenomics (PGx) samples may be conducted as appropriate. 
Detailed instructions for the handling and shipping of samples are provided in the appropriate
Study Manual.
9.1.17 Tuberculosis Screening 
All subjects will complete TB screening to determine eligibility. Subjects will be excluded from 
the study if they have active or latent TB, regardless of treatment history, as defined in 
Section 7.2.2. 
9.1.18 Fecal Calprotectin Sample Collection
A stool sample will be collected for the analysis of fecal calprotectin, a biomarker of intestinal 
inflammatory activity, as shown in the Schedule of Events (Appendix A).

9.1.19 Stool Sample
A stool sample will be obtained for culture, ova and parasite evaluation, and C. difficile assay. A 
sample will be collected and cultured during screening and at any point in the study when a subject 
becomes symptomatic, including worsening or return of disease activity.
9.1.20 PML Checklist 
9.1.21 Patient-Reported Outcomes Instruments 
Subjects will complete the IBDQ and EQ-5D health related quality of life (HRQOL) 
questionnaires at the time points specified in the schedule of events. Subjects will also complete 
the WPAI-UC to assess the impact on loss of work productivity and activity impairment.
9.1.21.1 Inflammatory Bowel Disease Questionnaire
The IBDQ is a valid and reliable [30] instrument used to assess health-related quality of life 
(HRQOL) in adult subjects with IBD. It includes 32 questions on 4 domains of HRQOL: Bowel 
Systems (10 items), Emotional Function (12 items), Social Function (5 items), and Systemic 
Function (5 items). Subjects are asked to recall symptoms and quality of life from the last 2 weeks 
and rate each item on a 7-point Likert scale (higher scores equate to higher quality of life). A total 
IBDQ score is calculated by summing the scores from each domain; the total IBDQ score ranges 
from 32 to 224.
9.1.21.2 EQ-5D Questionnaire
The EQ-5D questionnaire, developed by the ‘EuroQol Research Foundation’ is a simple, valid, 
and reliable [31] instrument used to measure general HRQOL in subjects and includes five domain 
items - mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Subjects 
choose the level of health problems they currently have on each item as “None”, “Moderate”, or 
“Extreme” and are scored a 1, 2, or 3, respectively. A composite EQ-5D score can be calculated 
from the individual scores to assess overall HRQOL. The EQ-5D visual analog score (VAS) score 
is a self-assigned rating of overall health using a 20 cm visual, vertical scale, with a score of 0 as 
the worst and 100 as best possible health. The EQ-5D total score and EQ-5D VAS score have been

shown in many studies to be valid and reliable instruments for measuring HRQOL in patients with 
GI diseases.
9.1.21.3 Work Productivity and Activity Impairment-UC
The WPAI questionnaire is a valid and reliable [32] 6-item instrument that consists of four metrics: 
absenteeism (the percentage of work time missed because of one’s health in the past seven days), 
presenteeism (the percentage of impairment experienced while at work in the past seven days 
because of one’s health), overall work productivity loss (an overall impairment estimate that is a 
combination of absenteeism and presenteeism), and activity impairment (the percentage of 
impairment in daily activities because of one’s health in the past seven days). The sum of specific 
health problem impairment and impairment due to other health reasons is equal to impairment due 
to all health reasons. WPAI outcomes are expressed as impairment percentages, with higher 
numbers indicating greater impairment and less productivity, ie, worse outcomes. WPAI-UC is the 
specific disease version of the questionnaire.
9.1.22 Documentation of Screen Failure
Investigators must account for all subjects who sign informed consent.
If the subject is found to be not eligible during screening, the investigator should contact the IWRS 
as a notification of screen failure and complete the Screen Failure eCRF. 
The primary reason for screen failure is recorded in the eCRF using the following categories:

PTE/AE.

Did not meet inclusion criteria or did meet exclusion criteria. 

Significant protocol deviation.

Lost to follow-up.

Voluntary withdrawal <specify reason>.

Study termination.

Other <specify reason>.
Subject numbers assigned to subjects who fail screening should not be reused. Re-screening of 
subjects will be assessed by the Medical Monitor on a case by case basis.
9.1.23 Documentation of Study Entrance
Only subjects who meet all of the inclusion criteria and none of the exclusion criteria at Week 0 are 
eligible for enrolment into the Induction Phase.
At Week 6 subjects will be assessed for eligibility for randomization into the Maintenance Phase. 
If the subject is found to be not eligible for the study, the Investigator should record the primary 
reason for failure on the applicable eCRF.

Monitoring Subject Treatment Compliance
If a subject is persistently noncompliant with the study medication, it may be appropriate to 
withdraw the subject from the study. All subjects should be reinstructed about the dosing 
requirement during study contacts. The authorized study personnel conducting the re-education 
must document the process in the subject source records.
9.3
Schedule of Observations and Procedures
The schedule for all study-related procedures for all evaluations is shown in Appendix A. 
Assessments should be completed at the designated visit/time point(s).
9.3.1
Screening 
Subjects will be screened within 28 days prior to enrollment. Subjects will be screened in 
accordance with predefined inclusion and exclusion criteria as described in Section 7.0. See 
Section 9.1.22 for procedures for documenting screening failures.
Procedures to be completed at screening can be found in the schedule of events (Appendix A). 
9.3.2
Enrollment/Randomization 
Enrollment will take place at Week 0. If the subject has satisfied all of the inclusion criteria and 
none of the exclusion criteria, the subject should be enrolled using the IWRS. Subjects will be 
instructed on when the first dose of investigational drug will be given as described in Section 6.1. 
The procedure for documenting screening failures is provided in Section 9.1.22.
Eligible subjects will receive open-label infusions of vedolizumab IV 300 mg at Weeks 0 and 2, 
and will be assessed for clinical response (endoscopy score determined by a central reader) at 
Week 6. Subjects with clinical response at Week 6 will be randomized at a 2:1:1 ratio to receive 
beginning at Week 6 through Week 50:

Injections of active vedolizumab SC 108 mg Q2W and placebo IV infusions Q8W (N=94).

Infusions of active vedolizumab IV 300 mg Q8W and placebo SC injections Q2W (N=47).

Placebo SC injections Q2W and placebo IV infusions Q8W (N=47).
Randomization will be stratified by:

Concomitant use of oral corticosteroids.

Remission status at Week 6.

Previous TNF-α antagonists failure or concomitant immunomodulator (azathioprine, 
6-mercaptopurine) use.

The Final Visit will be performed on Week 52 or at ET for all subjects.
For all subjects receiving study medication, the investigator must complete the End of Study eCRF 
page.
Subjects who complete the study will be offered entry into the OLE study after completion of the 
Week 52 assessment.
Subjects who are withdrawn from the study due to disease worsening (Section 3.5) will be offered 
entry into the OLE study. 
From Week 14 onwards, subjects who are withdrawn from the study due to need for rescue 
medications, despite not meeting the criteria for disease worsening, will be offered entry into the 
OLE study. Need for rescue medications are defined in Section 7.3.1.
Subjects who are discontinued from the study due to study drug related AEs or to requiring 
surgical intervention for their UC will not be eligible to enroll into the OLE study. 
9.3.4
Final Safety Follow-up Visit
For those subjects not entering the OLE study or are discontinued, a Final Safety Follow-up Visit 
will be performed 18 weeks after the last dose of study drug. Assessments will be completed per 
the schedule of events Week 68 Visit. For subjects that are not in response at Week 14, ET 
procedures will be performed at the Week 14 visit.
9.3.5
Post Study 6-Month Long-Term Follow-Up Survey
Upon completion of or early termination from the study, all subjects not entering the OLE study 
will be required to participate by telephone in a 6 month LTFU safety questionnaire (from the last 
dose received).
9.3.6
Unscheduled Visits Due to Disease Exacerbation 
Subjects who are seen by the investigator or site staff at a time point not required by the protocol 
(ie, unscheduled visit) due to disease exacerbation will undergo the following: 

Physical examination. 

Vital signs assessment. 

Diary review.


Collection of concomitant medications and procedures.

Collection of AEs and SAEs.

Clinical chemistry and hematology, as indicated.

Partial or complete Mayo score.

Flexible sigmoidoscopy, if indicated.

PK sample collection.

AVA sample collection.

C. difficile, if indicated.
There is no minimum time for repeat evaluation by unscheduled visit in order to determine if a 
subject meets the criteria for disease worsening. In general, however, enough time should be 
provided for clinically meaningful change to occur. 
9.4
Biological Sample Retention and Destruction
In this study, whole blood and mucosal tissue specimens for pharmacology and histology analysis 
will be collected as described. The samples will be sent to a central laboratory that processes the 
samples and serves as a secure storage facility. The sponsor and researchers working with the 
sponsor will have access to the samples collected and any test results. All samples collected during 
the study will be stored securely with limited access and the sponsor will require anyone who 
works with the samples to agree to hold the research information and any results in confidence.
Samples will be stored for no longer than 15 years after completion of the study. No samples will 
be stored for longer than permitted by the applicable law and samples will be destroyed upon 
notification from Takeda. 
The sample will be labeled with a unique sample identifier similar to labeling in the main study but 
using a code that is different from the code attached to the health information and other clinical test 
results collected in the study. The sample and data are linked to personal health information with 
code numbers. This link means that the subject may be identified but only indirectly. The code 
numbers will be kept secure by or on behalf of the sponsor.
Subjects who consented and provided pharmacogenomic samples can withdraw their consent and 
request disposal of a stored sample (blood and/or tissue) at any time. The sponsor will be notified 
of consent withdrawal.

PRETREATMENT EVENTS (PTE), ADVERSE EVENTS (AE) AND PRODUCT 
COMPLAINTS (PC)
10.1
Definitions
10.1.1 PTEs
A Pre-Treatment Event (PTE) is defined as any untoward medical occurrence in a clinical 
investigation subject who has signed informed consent to participate in a study but prior to 
administration of any study medication; it does not necessarily have to have a causal relationship 
with study participation.
10.1.2 AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a drug whether or 
not it is considered related to the drug.
In addition, drug-device AEs related to quality or malfunction will be collected.
10.1.3 Additional Points to Consider for PTEs and AEs
An untoward finding generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition. (Intermittent 
events for pre existing conditions underlying disease should not be considered PTEs or AEs.)

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study medication or a concomitant medication.

Be considered unfavorable by the investigator for any reason.

PTEs/AEs caused by a study procedure (eg, a bruise after blood draw) should be recorded as a 
PTE/AE.
Diagnoses vs signs and symptoms:

Each event should be recorded to represent a single diagnosis. Accompanying signs (including 
abnormal laboratory values or ECG findings) or symptoms should NOT be recorded as 
additional AEs. If a diagnosis is unknown, sign(s) or symptom(s) should be recorded 
appropriately as a PTE(s) or as an AE(s).

Vedolizumab SC
Study No. MLN0002SC-3027
Page 68 of 109
Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
Laboratory values and ECG findings:

Changes in laboratory values or ECG parameters are only considered to be PTEs or AEs if they 
are judged to be clinically significant (ie, if some action or intervention is required or if the 
investigator judges the change to be beyond the range of normal physiologic fluctuation). A 
laboratory re-test and/or continued monitoring of an abnormal value are not considered an 
intervention. In addition, repeated or additional noninvasive testing for verification, evaluation 
or monitoring of an abnormality is not considered an intervention.

If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (eg, increased creatinine in renal failure), the diagnosis only should be 
reported appropriately as a PTE or as an AE.
Pre-existing conditions:

Pre-existing conditions (present at the time of signing of informed consent) are considered 
concurrent medical conditions and should NOT be recorded as PTEs or AEs. Baseline 
evaluations (eg, laboratory tests, ECG, X-rays etc.) should NOT be recorded as PTEs unless 
related to study procedures. However, if the subject experiences a worsening or complication 
of such a concurrent condition, the worsening or complication should be recorded 
appropriately as a PTE (worsening or complication occurs before start of study medication) or 
an AE (worsening or complication occurs after start of study medication). Investigators should 
ensure that the event term recorded captures the change in the condition (eg, “worsening 
of…”).

If a subject has a pre-existing episodic condition (eg, asthma, epilepsy) any occurrence of an 
episode should only be captured as a PTE/AE if the episodes become more frequent, serious or 
severe in nature, that is, investigators should ensure that the AE term recorded captures the 
change in the condition from Baseline (eg, “worsening of…”).

If a subject has a degenerative concurrent condition (eg, cataracts, rheumatoid arthritis), 
worsening of the condition should only be captured as a PTE/AE if occurring to a greater 
extent to that which would be expected. Again, investigators should ensure that the AE term 
recorded captures the change in the condition (eg, “worsening of…”).
Worsening of PTEs or AEs:

If the subject experiences a worsening or complication of a PTE after starting administration of 
the study medication, the worsening or complication should be recorded appropriately as an 
AE. Investigators should ensure that the AE term recorded captures the change in the condition 
(eg, “worsening of…”).

If the subject experiences a worsening or complication of an AE after any change in study 
medication, the worsening or complication should be recorded as a new AE. Investigators 
should ensure that the AE term recorded captures the change in the condition (eg, “worsening 
of…”).

Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
Changes in severity of AEs /Serious PTEs:

If the subject experiences changes in severity of an AE/serious PTE, the event should be 
captured once with the maximum severity recorded.
Preplanned surgeries or procedures:

Preplanned procedures (surgeries or therapies) that were scheduled prior to signing of 
informed consent are not considered PTEs or AEs. However, if a preplanned procedure is 
performed early (eg, as an emergency) due to a worsening of the pre-existing condition, the 
worsening of the condition should be captured appropriately as a PTE or an AE. Complications 
resulting from any planned surgery should be reported as AEs.
Elective surgeries or procedures:

Elective procedures performed where there is no change in the subject’s medical condition 
should not be recorded as PTEs or AEs, but should be documented in the subject’s source 
documents. Complications resulting from an elective surgery should be reported as AEs.
Insufficient clinical response (lack of efficacy):

Insufficient clinical response, efficacy, or pharmacologic action, should NOT be recorded as 
an AE. The investigator must make the distinction between exacerbation of pre-existing illness 
and lack of therapeutic efficacy.
Overdose:

Cases of overdose with any medication without manifested side effects are NOT considered 
PTEs or AEs, but instead will be documented on an Overdose page of the eCRF. Any 
manifested side effects will be considered PTEs or AEs and will be recorded on the AE page of 
the eCRF.
10.1.4 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
if it were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. Is a CONGENITAL ANOMALY/BIRTH DEFECT.

6. Is an IMPORTANT MEDICAL EVENT that satisfies any of the following:

May require intervention to prevent items 1 through 5 above.

May expose the subject to danger, even though the event is not immediately life 
threatening or fatal or does not result in hospitalization.

Includes any event or synonym described in the Takeda Medically Significant AE List 
(Table 10.a).
Table 10.a

Spontaneous abortion / stillbirth and fetal death
PTEs that fulfill 1 or more of the serious criteria above are also to be considered SAEs and should 
be reported and followed up in the same manner (see Sections 10.2.2 and 10.3).
10.1.5 Special Interest AEs
A Special Interest Adverse Event (serious or nonserious) is one of scientific and medical concern 
specific to the compound or program, for which ongoing monitoring and rapid communication by 
the investigator to Takeda may be appropriate. Such events may require further investigation in 
order to characterize and understand them and would be described in protocols and instructions 
provided for investigators as to how and when they should be reported to Takeda. Refer to 
Section 10.2.1.4 for information for special interest AE reporting. 
10.1.6 Severity of PTEs and AEs
The different categories of intensity (severity) are characterized as follows:
Mild:
The event is transient and easily tolerated by the subject.
Moderate:
The event causes the subject discomfort and interrupts the subject’s usual activities.
Severe:
The event causes considerable interference with the subject’s usual activities.

CONFIDENTIAL
10.1.7 Causality of AEs
The relationship of each AE to study medication(s) will be assessed using the following 
categories:
Related:
An AE that follows a reasonable temporal sequence from administration of a drug (including the 
course after withdrawal of the drug), or for which possible involvement of the drug cannot be 
ruled out, although factors other than the drug, such as underlying diseases, complications, 
concomitant drugs and concurrent treatments, may also be responsible.
Not Related:
An AE that does not follow a reasonable temporal sequence from administration of a drug and/or 
that can reasonably be explained by other factors, such as underlying diseases, complications, 
concomitant drugs and concurrent treatments.
10.1.8 Relationship to Study Procedures
Relationship (causality) to study procedures should be determined for all PTEs and AEs.
The relationship should be assessed as Related if the investigator considers that there is reasonable 
possibility that an event is due to a study procedure. Otherwise, the relationship should be assessed 
as Not Related. 
10.1.9 Start Date
The start date of the AE/PTE is the date that the first signs/symptoms were noted by the subject 
and/or physician.
10.1.10
Stop Date 
The stop date of the AE/PTE is the date at which the subject recovered, the event resolved but with 
sequelae or the subject died.
10.1.11
Frequency 
Episodic AEs/PTE (eg, vomiting) or those which occur repeatedly over a period of consecutive 
days are intermittent. All other events are continuous.
10.1.12
Action Concerning Study Medication 

Drug withdrawn – a study medication is stopped due to the particular AE.

Dose not changed – the particular AE did not require stopping a study medication.

Unknown – only to be used if it has not been possible to determine what action has been taken.

Not Applicable – a study medication was stopped for a reason other than the particular AE eg, 
the study has been terminated, the subject died, dosing with study medication was already 
stopped before the onset of the AE.

Dose Interrupted – the dose was interrupted due to the particular AE.

10.1.13
Outcome

Recovered/Resolved – Subject returned to first assessment status with respect to the AE/PTE.

Recovering/Resolving – the intensity is lowered by one or more stages: the diagnosis or 
signs/symptoms has almost disappeared; the abnormal laboratory value improved, but has not 
returned to the normal range or to baseline; the subject died from a cause other than the 
particular AE/PTE with the condition remaining “recovering/resolving”.

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/ symptoms or laboratory value on the last day of the observed 
study period has got worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE/PTE state remaining “Not 
recovered/not resolved”.

Resolved with sequelae – the subject recovered from an acute AE/PTE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis.

Fatal – the AEs/PTEs which are considered as the cause of death. 

Unknown – the course of the AE/PTE cannot be followed up due to hospital change or 
residence change at the end of the subject’s participation in the study.
10.1.14
Product Complaints
A product complaint (PC) is a verbal, written, or electronic expression that implies dissatisfaction 
regarding the identity, strength, purity, quality, or stability of a drug product and/or device 
(eg, prefilled syringe).
An investigator who is made aware of or identifies a potential PC should immediately report the 
event to Takeda in accordance with the contact list provided to the site. Whenever possible, the 
associated product should be maintained in accordance with the instructions pending further 
guidance from a Takeda representative. Refer to the appropriate study manual provided separately 
for additional information (depending on local regulations).
10.2
Procedures
10.2.1 Collection and Reporting of AEs
10.2.1.1 PTE and AE Collection Period

Start of AE collection: AEs must be collected from start of study medication administration. 

End of AE collection: AEs must be collected for 18 weeks following the last dose of study 
medication. 

Collection of PTEs will commence from the time the subject signs the informed consent to 
participate in the study and continue until the subject is first administered study medication or

until screen failure. For subjects who discontinue prior to study medication administration, 
PTEs are collected until the subject discontinues study participation.

Collection of AEs will commence from the time that the subject is first administered study 
medication (enrollment). Routine collection of AEs will continue until 18 weeks after last 
dose.
10.2.1.2 PTE and AE Reporting
At each study visit, the investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. Subjects experiencing a 
serious PTE must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or there is a satisfactory explanation for the change. 
Non-serious PTEs, related or unrelated to the study procedure, need not to be followed-up for the 
purposes of the protocol.
All subjects experiencing AEs, whether considered associated with the use of the study medication 
or not, must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or until there is a satisfactory explanation for the 
changes observed. All PTEs and AEs will be documented in the PTE/AE page of the eCRF, 
whether or not the investigator concludes that the event is related to the drug treatment. The 
following information will be documented for each event:
1. Event term.
2. Start and stop date (and time, if deemed directly related to the study drug administration).
3. Severity.
4. Investigator’s opinion of the causal relationship between the event and administration of study 
medication(s) (related or not related) (not completed for PTEs).
5. Investigator’s opinion of the causal relationship to study procedure(s), including the details of 
the suspected procedure.
6. Action concerning study medication (not applicable for PTEs).
7. Outcome of event.
8. Seriousness.
Several patient-reported outcomes measures will be used in this study (eg, IBDQ, EQ5D, 
WPAI-UC). They will not be used as a primary means to collect AEs. However, should the 
investigator become aware of a potential AE through the information collected with this 
instrument, proper follow-up with the subject for medical evaluation should be undertaken. 
Through this follow-up, if it is determined that an AE not previously reported has been identified, 
normal reporting requirements should be applied.

10.2.1.3 Adverse Event Collection Involving Medically Anticipated Clinical Events 
UC is associated with certain characteristic signs and symptoms, including diarrhea and rectal 
bleeding, that may be present at baseline and persist or fluctuate based on the individual subject’s 
disease history during the course of the study. These signs and symptoms will not be collected as 
AEs. These characteristics of disease activity will be regularly captured in the Mayo score. 
Exacerbations of disease activity (eg, increase in the daily amount of rectal bleeding beyond the 
subject’s normal fluctuation, new signs and symptoms of UC) will be collected as AEs and 
reported according to regulatory reporting requirements. 
Extra-intestinal manifestations of the subject’s disease (eg, arthralgia, arthritis, uveitis) that 
develop or worsen during the study are considered AEs. 
10.2.1.4 Special Interest AE Reporting
If this special interest AE, which occurs during the treatment period or the follow-up period, is 
considered to be clinically significant based on the criteria below, it should be recorded in a special 
interest AE eCRF or SAE Form. The applicable form should be completed and reported to the 
SAE reporting contact in Section 1.1 within 24 hours.
Hypersensitivity Reactions (Including Injection Site Reactions)
Currently, there is no evidence to support the routine prophylactic administration of premedication 
(eg, antihistamines, corticosteroids) to subjects receiving vedolizumab; hence such 
premedications are unlikely to be necessary or beneficial. At the discretion of the investigator, 
however, subjects may be administered premedication prior to any study drug administration. 
Corticosteroids, if given as a premedication, should be limited to the day of administration. 
Vedolizumab IV should be administered by a HCP prepared to manage hypersensitivity reactions 
including anaphylaxis, if they occur. Appropriate monitoring and medical support measure should 
be available for immediate use. Subjects should be observed for 2 hours following the first 
2 infusions, at a minimum, and one hour after each subsequent infusion.
During clinic visits, subjects should be observed during the SC administration and for one hour 
following completion of the administration. Vedolizumab SC should be administered by the 
subject or caregiver in the presence of a HCP prepared to manage hypersensitivity reactions 
including anaphylaxis, if they occur. Appropriate monitoring and medical support measures 
should be available for immediate use. 
Subjects and caregivers will be instructed to report the development of rash, hives, pruritus, 
flushing, urticaria, injections site pain, redness and/or swelling, etc. that may represent an 
administration-related reaction (ie, injection-site reaction or infusion-related reaction) to study 
medication. Subjects will be asked to report administration-related AEs to the sites immediately as 
they are experienced or after having received appropriate medical care. Appropriate treatment and 
follow-up will be determined by the investigator. If signs or symptoms of an 
administration-related reaction are observed during the administration of study medication, it 
should be immediately discontinued and the subject treated as medically appropriate. In the case of 

Vedolizumab SC
Study No. MLN0002SC-3027

Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
a mild reaction, study drug administration may be reinitiated (with appropriate premedication and 
investigator supervision) at the discretion of the investigator. Subjects with a severe or serious 
administration-related reaction (eg, shortness of breath, wheezing, stridor, angioedema, 
life-threatening change in vital signs, severe injection site reactions) must be withdrawn from the 
study (see appropriate Study Manual). 
In all cases of administration-related reaction, the medical monitor must be informed as soon as 
practical. The disposition of subjects with less severe administration-related reactions should be 
discussed with the medical monitor. 
Serious Infections 
Subjects will be monitored for signs and symptoms of infection and for lymphopenia during the 
study. Subjects with signs and symptoms suggestive of infections, including GI infections, will be 
treated as clinically indicated. Interventions may include antibiotic treatment, if appropriate and/or 
discontinuation of concomitant immunomodulators. Blood, sputum, urine, and/or stool cultures 
should be obtained as appropriate for the detection and diagnosis of infection. Withholding or 
terminating study drug administration may be considered as described in Section 7.4.
Malignancy 
All cases of malignancies that are detected during the study will be reported as AEs. Local medical 
practices for the management of malignances will apply. Subjects with history of malignancy 
(except for specific cancers) or at high risk for malignancy will be excluded from the study per the 
exclusion criteria. 
Other 
Other special interest AEs include liver injury and PML, which are discussed in Sections 10.2.3
and 11.2.1 respectively.
10.2.2 Collection and Reporting of SAEs
When an SAE occurs through the AE collection period it should be reported according to the 
following procedure:
A Takeda SAE eCRF or Form must be completed, in English, and signed by the investigator 
immediately or within 24 hours of first onset or notification of the event. The information should 
be completed as fully as possible but contain, at a minimum:

A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study medication(s).

Causality assessment.

Study No. MLN0002SC-3027
Page 76 of 109
Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
The SAE eCRF should be completed within 24 hours of first onset or notification of the event. 
However, as a back-up, if required, the SAE Form should be completed and reported to Takeda 
Pharmacovigilance or designee within 24 hours to the attention of the contact listed in Section 1.1.
Any SAE spontaneously reported to the investigator following the AE collection period should be 
reported to the sponsor if considered related to study participation.
Reporting of Serious PTEs will follow the procedure described for SAEs.
*Note: For Japanese sites, the investigator should report the detailed paper SAE report provided by 
sponsor or by the institution without delay after notification of initial information. Additional 
detailed follow-up data surrounding the serious adverse event that becomes available following 
the initial report should be communicated through the same channels as outlined above.
10.2.3 Reporting of Abnormal Liver Function Tests 
If a subject is noted to have ALT or AST elevated >3 ×ULN on 2 consecutive occasions, the 
abnormality should be recorded as an AE. In addition, an LFT Increases eCRF must be completed 
providing additional information on relevant recent history, risk factors, clinical signs and 
symptoms and results of any additional diagnostic tests performed.
If a subject is noted to have ALT or AST >3 ×ULN and total bilirubin >2 ×ULN for which an 
alternative etiology has not been identified, the event should be recorded as an SAE and reported 
as per Section 10.2.2. The investigator must contact the medical monitor for discussion of the 
relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or B or 
other acute liver disease or medical history/concurrent medical conditions. Follow-up laboratory 
tests as described in Section 9.1.9 must also be performed. In addition, an LFT Increases eCRF 
must be completed and transmitted with the Takeda SAE Form (as per Section 10.2.2).
10.3
Follow-up of SAEs
If information not available at the time of the first report becomes available at a later date, the 
investigator should complete a follow-up SAE form or provide other written documentation and 
fax it immediately within 24 hours of receipt. Copies of any relevant data from the hospital notes 
(eg, ECGs, laboratory tests, discharge summary, postmortem results) should be sent to the 
addressee, if requested.
All SAEs should be followed up until resolution or permanent outcome of the event. The timelines 
and procedure for follow-up reports are the same as those for the initial report.
10.3.1 Safety Reporting to Investigators, IRBs or IECs, and Regulatory Authorities
The sponsor will be responsible for reporting all suspected unexpected serious adverse reactions 
(SUSARs) and any other applicable SAEs to regulatory authorities, including the European 
Medicines Agency (EMA), investigators and IRBs or IECs, as applicable, in accordance with 
national regulations in the countries where the study is conducted. Relative to the first awareness 
of the event by/or further provision to the sponsor or sponsor’s designee, SUSARs will be

submitted to the regulatory authorities as expedited report within 7 days for fatal and 
life-threatening events and 15 days for other serious events, unless otherwise required by national 
regulations. The sponsor will also prepare an expedited report for other safety issues where these 
might materially alter the current benefit-risk assessment of an investigational medicinal product 
or that would be sufficient to consider changes in the investigational medicinal products 
administration or in the overall conduct of the trial. The investigational site also will forward a 
copy of all expedited reports to his or her IRB or IEC in accordance with national regulations.

DATA HANDLING AND RECORD KEEPING
The full details of procedures for data handling will be documented in the Data Management Plan. 
AEs, PTEs, medical history, and concurrent conditions will be coded using the Medical Dictionary 
for Regulatory Activities (MedDRA). Drugs will be coded using the World Health Organization 
(WHO) Drug Dictionary.
12.1
Electronic CRFs
Completed eCRFs are required for each subject who signs an informed consent.
The sponsor or its designee will supply investigative sites with access to eCRFs. The sponsor will 
make arrangements to train appropriate site staff in the use of the eCRFs. These forms are used to 
transmit the information collected in the performance of this study to the sponsor and regulatory 
authorities. eCRFs must be completed in English. Data are transcribed directly onto eCRFs.
After completion of the entry process, computer logic checks will be run to identify items, such as 
inconsistent dates, missing data, and questionable values. Queries may be issued by Takeda 
personnel (or designees) and will be answered by the site. 
Corrections are recorded in an audit trail that captures the old information, the new information, 
identification of the person making the correction, the date the correction was made, and the reason 
for change.
The principal investigator must review the eCRFs for completeness and accuracy and must sign 
and date the appropriate eCRFs as indicated. Furthermore, the investigator must retain full 
responsibility for the accuracy and authenticity of all data entered on the eCRFs.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by study monitors. The sponsor or its designee will be permitted to review the subject’s medical 
and hospital records pertinent to the study to ensure accuracy of the eCRFs. The completed eCRFs 
are the sole property of the sponsor and should not be made available in any form to third parties, 
except for authorized representatives of appropriate governmental health or regulatory authorities, 
without written permission of the sponsor.
12.2
Record Retention
1. The following procedure is applied for the countries except for Japan.
The investigator agrees to keep the records stipulated in Section 12.1 and those documents that 
include (but are not limited to) the study-specific documents, the identification log of all 
participating subjects, medical records, temporary media such as thermal sensitive paper, source 
worksheets, all original signed and dated informed consent forms, subject authorization forms 
regarding the use of personal health information (if separate from the informed consent forms), 
electronic copy of eCRFs, including the audit trail, and detailed records of drug disposition to

STATISTICAL METHODS
13.1
Statistical and Analytical Plans
A statistical analysis plan (SAP) will be prepared and finalized prior to database lock and 
unblinding of subjects’ treatment assignments. This document will provide further details 
regarding the definition of analysis variables and analysis methodology to address all study 
objectives.
A blinded data review meeting will be conducted prior to unblinding of subjects’ treatment 
assignment and database lock. This review will assess the accuracy and completeness of the study 
database, subject evaluability, and appropriateness of the planned statistical methods.
13.1.1 Analysis Sets
The Full Analysis Set (FAS) will include all randomized subjects who receive at least 1 dose of 
study drug. Subjects in this set will be analyzed according to the treatment they were randomized 
to receive.
The per-protocol (PP) population is a subset of the intent-to-treat population. The PP population 
consists of all subjects who do not violate the terms of the protocol in a way that would impact the 
study output significantly. All decisions to exclude subjects for the per-protocol population dataset 
will be made prior to the unblinding of the study. Analyses using the per-protocol population may 
be provided as a sensitivity analysis.
The Safety Analysis Set will include all subjects who receive at least 1 dose of study drug. Subjects 
in this set will be analyzed according to the treatment they actually received.
The PK evaluable population is defined as all subjects who receive at least 1 dose of study drug 
and have sufficient blood sampling to allow for PK evaluation.
13.1.2 Analysis of Demographics and Other Baseline Characteristics
Baseline and demographic information will be listed and summarized by treatment group and 
overall. For continuous variables, the summary will consist of descriptive statistics (number of 
subjects, mean, standard deviation, minimum, median, and maximum). For categorical variables, 
the summary will consist of number and percentage of subjects in each category.
Medical history and concurrent medical conditions will be summarized by system organ class and 
preferred term. Medication history and concomitant medications will be summarized by preferred 
term.
13.1.3 Efficacy Analysis
All statistical testing will be performed at 2-sided 0.05 level of significance. To control the overall 
Type I error rate for the comparison between vedolizumab SC and placebo groups for the primary 
and secondary endpoints, a hierarchical approach will be applied to the statistical testing of the 
secondary endpoints. The statistical inference for the first secondary endpoint of mucosal healing

will only be performed if the primary endpoint, proportion of subjects with clinical remission at 
Week 52, is statistically significant. The second secondary endpoint of durable clinical response 
will only be tested if the first secondary endpoint is statistically significant. Similarly, the third 
secondary endpoint of durable clinical remission will only be tested if the second secondary 
endpoint is statistically significant, and the fourth secondary endpoint of corticosteroids-free 
clinical remission will only be tested if the third secondary endpoint is statistically significant. 
Multiplicity will not be adjusted across additional endpoints.
The descriptive statistics of treatment effects and corresponding 95% CIs for the IV arm versus 
placebo for the primary and secondary efficacy endpoints will be presented.
The comparison between vedolizumab IV and placebo groups will be considered exploratory and 
hence will not be included in the multiplicity control procedure described above. All dichotomous 
efficacy endpoints will be analyzed using Cochran-Mantel-Haenszel tests for risk differences, 
stratified by randomization stratum. The descriptive statistics of treatment effects and 
corresponding 95% CIs for the IV arm versus placebo for the primary and secondary efficacy 
endpoints will be presented. All subjects with missing data for determination of endpoint status 
will be considered as a non-responder in the analysis. 
13.1.4 Resource Utilization and Patient Reported Outcomes (PRO)
All statistical testing will be performed at 2-sided 0.05 level of significance. To control the overall 
Type I error rate for the comparison between vedolizumab SC and placebo groups, a hierarchy 
approach will be applied to the PRO endpoints if the primary endpoint is significant. 
The order of testing of PRO endpoints in Section 5.2.3 will be finalized in SAP before database 
lock. 
Changes from Baseline to Week 52 in IBDQ, EQ-5D scores and WPAI-UC components will be 
analyzed in an Analysis of Covariance model with treatment as a factor and baseline score as a 
covariate. Changes from Week 6 to Week 52 will be analyzed in a similar fashion.
13.1.5 Pharmacokinetic Analysis
Concentrations of vedolizumab in serum will be summarized by scheduled time points using 
descriptive statistics. Individual serum concentration data versus time will be presented in a data 
listing.
A separate Data Analysis Plan will be created to describe the population PK analysis approach for 
this study. The results of all PK parameters derived from population PK analysis will be described 
in more detail in a separate Population Pharmacokinetic Analysis Report. Other analyses or 
methods may be used, if appropriate.
13.1.6 Other Analysis
The proportion of subjects with positive AVA (transient and persistent) and proportion of subjects 
with positive neutralizing AVA during the study will be summarized at each visit. 

Vedolizumab SC
Study No. MLN0002SC-3027
Page 84 of 109
Protocol Incorporating Amendment No. 05
28 September 2016
CONFIDENTIAL
A positive AVA subject is defined as a subject who has at least 1 positive AVA result in any 
post-baseline sample, and is further categorized as:

Transiently positive: defined as subjects with confirmed positive AVA in 1 sample at a 
post-dose visit.

Persistently positive: defined as subjects with confirmed positive AVA in 2 or more 
consecutive positive AVA samples at post-dose visits.
The serum titers of AVA are defined as low (<250), moderate (250-2500) and high (>6250). 
Note: these are subject to change depending on the dilution factor that is used at the time of testing.
The ECL assay has better drug tolerance than the ELISA assay used in previous clinical trials 
(including the phase 3 registration studies with vedolizumab IV), therefore allowing more samples 
that have higher drug levels or samples that have lower AVA titers to be detected. 
The impact of immunogenicity on PK, efficacy and safety (including injection site reactions and 
infusion related reactions) will be explored.
Time to UC-related hospitalizations, colectomies, and UC-related hospitalizations procedures will 
be analyzed using a Wei-Lin-Weissfeld Cox-regression model with treatment group, baseline 
complete Mayo score, randomization stratum, and geographic region as independent variables. For 
each of the components, the treatment groups will be compared by log-rank tests, with 
Kaplan-Meier estimates of Week 24 and Week 48 event rates presented.
13.1.7 Safety Analysis
Safety analysis will be performed using the Safety Analysis Set. No statistical inference will be 
made for safety analyses.
The number and percentage of subjects with TEAEs (defined as any AEs, regardless of 
relationship to study drug), AESIs (ie, serious infections including opportunistic infection such as 
PML, malignancies, liver injury, infusion reactions, injection site reactions), and SAEs which 
occur on or after the first dose date and up to 18 weeks after the last dose date of the study drug in 
subjects who do not enroll in open-label extension study or up to the first dose of the open-label 
extension study in those who do, will be summarized by Medical Dictionary for Regulatory 
Activities (MedDRA) System Organ Class, High Level Term, and Preferred Term overall, by 
severity, and by relationship to study drug for each treatment group. Separate summaries will also 
be generated for treatment-related adverse events overall and by severity. In addition to incident 
rates, exposure adjusted AE rates will be summarized as well.
Change from baseline in clinical laboratory tests and vital signs will be summarized by treatment 
group. Subjects with markedly abnormal values for laboratory tests and vital signs will be 
tabulated.
Additional summaries of TEAEs will be provided that only include TEAEs that occur in the 
Maintenance Phase between the Week 6 dose and 18 weeks after the last dose date of the study 
drug, or up to the first dose of the open-label extension study, whichever comes first.

Data from the LTFU survey will be summarized descriptively.
The shift in ECG interpretation from Baseline will be summarized by treatment group. Physical 
examination findings and PML checklist data will be presented in data listings.
13.2
Interim Analysis and Criteria for Early Termination
No interim analysis is planned.
13.3
Determination of Sample Size
Assuming a clinical remission rate of 42% for vedolizumab and 16% for placebo at Week 52, a 
sample size of 94 subjects in the vedolizumab SC group and 47 subjects in the placebo group will 
provide 90% power at a 2-sided 0.05 level of significance. To ensure a randomized sample size of 
188 subjects, assuming 47% of the subjects entering induction will achieve clinical response at 
Week 6, approximately 400 subjects will need to be enrolled into the study.
Assuming a mucosal healing rate of 52% for vedolizumab and 20% for placebo at Week 52, with a 
sample size of 94 subjects in the vedolizumab group and 47 subjects in the placebo group the first 
secondary endpoint of mucosal healing at Week 52 will be powered to at least 97% at a 2-sided 
0.05 level of significance.

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator and institution guarantee access to source documents by the sponsor or its 
designee (contract research organization) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee 
(as long as blinding is not jeopardized), including but not limited to the Investigator’s Binder, 
study medication, subject medical records, informed consent documentation, documentation of 
subject authorization to use personal health information (if separate from the informed consent 
forms), and review of eCRFs and associated source documents. It is important that the investigator 
and other study personnel are available during the monitoring visits and that sufficient time is 
devoted to the process.
14.2
Protocol Deviations
The investigator should not deviate from the protocol, except where necessary to eliminate an 
immediate hazard to study subjects. Should other unexpected circumstances arise that will require 
deviation from protocol-specified procedures, the investigator should consult with the sponsor or 
designee (and IRB or IEC, as required) to determine the appropriate course of action. There will be 
no exemptions (a prospectively approved deviation) from the inclusion or exclusion criteria.
The site should document all protocol deviations in the subject’s source documents. In the event of 
a significant deviation, the site should notify the sponsor or its designee (and IRB or EC, as 
required). Significant deviations include, but are not limited to, those that involve fraud or 
misconduct, increase the health risk to the subject, or confound interpretation of primary study 
assessment. 
Significant protocol deviations will be entered into the eCRF, which is reviewed by the study 
sponsor or designee.
The procedure below applies to Japanese sites only.
The investigator can deviate and change from the protocol for any medically unavoidable reason, 
for example, to eliminate an immediate hazard to study subjects, without a prior written agreement 
with the sponsor or a prior approval from IRB. In the event of a deviation or change, the 
investigator should notify the sponsor and the head of the study site of the deviation or change as 
well as its reason in a written form, and then retain a copy of the written form. When necessary, the 
investigator may consult and agree with the sponsor on a protocol amendment. If the protocol 
amendment is appropriate, the amendment proposal should be submitted to the head of the study 
site as soon as possible and an approval from IRB should be obtained. The investigator should 
document all protocol deviations.

Quality Assurance Audits and Regulatory Agency Inspections
The study site also may be subject to quality assurance audits by the sponsor or designees. In this 
circumstance, the sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the medication is stored and prepared, and any other facility used during the study. In 
addition, there is the possibility that this study may be inspected by regulatory agencies, including 
those of foreign governments (eg, the Food and Drug Administration (FDA), the United Kingdom 
Medicines and Healthcare products Regulatory Agency, the Pharmaceuticals and Medical Devices 
Agency of Japan). If the study site is contacted for an inspection by a regulatory body, the sponsor 
should be notified immediately. The investigator and institution guarantee access for quality 
assurance auditors to all study documents as described in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This study will be conducted with the highest respect for the individual participants (ie, subjects) 
according to the protocol, the ethical principles that have their origin in the Declaration of 
Helsinki, and the ICH Harmonised Tripartite Guideline for GCP. Each investigator will conduct 
the study according to applicable local or regional regulatory requirements and align his or her 
conduct in accordance with the “Responsibilities of the Investigator” that are listed in Appendix B. 
The principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
15.1
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable state and federal/local requirements 
of each participating region. The sponsor or designee will require documentation noting all names 
and titles of members who make up the respective IRB or IEC. If any member of the IRB or IEC 
has direct participation in this study, written notification regarding his or her abstinence from 
voting must also be obtained. Those Americas sites unwilling to provide names and titles of all 
members due to privacy and conflict of interest concerns should instead provide a Federal Wide 
Assurance Number or comparable number assigned by the Department of Health and Human 
Services.
The sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure, a copy of 
the informed consent form, and, if applicable, subject recruitment materials and/or advertisements 
and other documents required by all applicable laws and regulations, must be submitted to a 
central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the protocol and 
subject informed consent must be obtained and submitted to the sponsor or designee before 
commencement of the study (ie, before shipment of the sponsor-supplied drug or study specific 
screening activity). The IRB or IEC approval must refer to the study by exact protocol title, 
number, and version date; identify versions of other documents (eg, informed consent form) 
reviewed; and state the approval date. The sponsor will ship drug and notify site once the sponsor 
has confirmed the adequacy of site regulatory documentation and, when applicable, the sponsor 
has received permission from competent authority to begin the trial. Until the site receives 
notification no protocol activities, including screening may occur.
Sites must adhere to all requirements stipulated by their respective IRB or IEC. This may include 
notification to the IRB or IEC regarding protocol amendments, updates to the informed consent 
form, recruitment materials intended for viewing by subjects, local safety reporting requirements, 
reports and updates regarding the ongoing review of the study at intervals specified by the 
respective IRB or IEC, and submission of the investigator’s final status report to IRB or IEC. All 
IRB and IEC approvals and relevant documentation for these items must be provided to the 
sponsor or its designee.
Subject incentives should not exert undue influence for participation. Payments to subjects must 
be approved by the IRB or IEC and sponsor.

Regarding any future pharmacogenomic investigation using collected and stored specimens for 
Japan; the sponsor will create a research protocol for pharmacogenomics investigations and the 
research protocol will require prior approval of the respective IRB in Japan prior to use.
15.2
Subject Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in the 
Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance with all 
applicable laws and regulations. The informed consent form, subject authorization form (if 
applicable), and subject information sheet (if applicable) describe the planned and permitted uses,
transfers, and disclosures of the subject’s personal and personal health information for purposes of 
conducting the study. The informed consent form and the subject information sheet (if applicable) 
further explain the nature of the study, its objectives, and potential risks and benefits, as well as the 
date informed consent is given. The informed consent form will detail the requirements of the 
participant and the fact that he or she is free to withdraw at any time without giving a reason and 
without prejudice to his or her further medical care.
The investigator is responsible for the preparation, content, and IRB or IEC approval of the 
informed consent form and if applicable, the subject authorization form. The informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) must 
be approved by both the IRB or IEC and the sponsor prior to use.
The informed consent form, subject authorization form (if applicable), and subject information 
sheet (if applicable) must be written in a language fully comprehensible to the prospective subject. 
It is the responsibility of the investigator to explain the detailed elements of the informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) to the 
subject. Information should be given in both oral and written form whenever possible and in the 
manner deemed appropriate by the IRB or IEC. In the event the subject is not capable of rendering 
adequate written informed consent, then the subject’s legally acceptable representative may 
provide such consent for the subject in accordance with applicable laws and regulations.
The subject, or the subject’s legally acceptable representative, must be given ample opportunity to: 
(1) inquire about details of the study and (2) decide whether or not to participate in the study. If the 
subject, or the subject’s legally acceptable representative, determines he or she will participate in 
the study, then the informed consent form and subject authorization form (if applicable) must be 
signed and dated by the subject, or the subject’s legally acceptable representative, at the time of 
consent and prior to the subject entering into the study. The subject or the subject’s legally 
acceptable representative should be instructed to sign using their legal names, not nicknames, 
using blue or black ballpoint ink. The investigator must also sign and date the informed consent 
form and subject authorization (if applicable) at the time of consent and prior to subject entering 
into the study; however, the sponsor may allow a designee of the investigator to sign to the extent 
permitted by applicable law.
Once signed, the original informed consent form, subject authorization form (if applicable), and 
subject information sheet (if applicable) will be stored in the investigator’s site file. The 

Vedolizumab SC
Study No. MLN0002SC-3027

investigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed informed consent form, the signed subject authorization form 
(if applicable), and subject information sheet (if applicable) shall be given to the subject.
All revised informed consent forms must be reviewed and signed by relevant subjects or the 
relevant subject’s legally acceptable representative in the same manner as the original informed 
consent. The date the revised consent was obtained should be recorded in the subject’s medical 
record, and the subject should receive a copy of the revised informed consent form.
15.3
Subject Confidentiality
The sponsor and designees affirm and uphold the principle of the subject’s right to protection 
against invasion of privacy. Throughout this study, a subject’s source data will only be linked to 
the sponsor’s clinical study database or documentation via a unique identification number. As 
permitted by all applicable laws and regulations, limited subject attributes, such as sex, age, or date 
of birth, and subject initials may be used to verify the subject and accuracy of the subject’s unique 
identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit its monitor or designee’s monitor, representatives from any 
regulatory authority (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs and IECs to review the subject’s original medical records (source data or 
documents), including, but not limited to, laboratory test result reports, ECG reports, admission 
and discharge summaries for hospital admissions occurring during a subject’s study participation, 
and autopsy reports. Access to a subject’s original medical records requires the specific 
authorization of the subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and/or advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and

review of the document. All publications and presentations must be prepared in accordance with 
this section and the Clinical Study Site Agreement. In the event of any discrepancy between the 
protocol and the Clinical Study Site Agreement, the Clinical Study Site Agreement will prevail.
15.4.2 Clinical Trial Registration
In order to ensure that information on clinical trials reaches the public in a timely manner and to 
comply with applicable laws, regulations and guidance, Takeda will, at a minimum register 
interventional clinical trials it sponsors anywhere in the world on ClinicalTrials.gov or other 
publicly accessible websites before start of study, as defined in Takeda Policy/Standard. Takeda 
contact information, along with investigator’s city, state (for Americas investigators), country, and 
recruiting status will be registered and available for public viewing. 
For some registries, Takeda will assist callers in locating trial sites closest to their homes by 
providing the investigator name, address, and phone number to the callers requesting trial 
information. Once subjects receive investigator contact information, they may call the site 
requesting enrollment into the trial. The investigative sites are encouraged to handle the trial 
inquiries according to their established subject screening process. If the caller asks additional 
questions beyond the topic of trial enrollment, they should be referred to the sponsor. 
Any investigator who objects to Takeda providing this information to callers must provide Takeda 
with a written notice requesting that their information not be listed on the registry site. 
15.4.3 Clinical Trial Results Disclosure
Takeda will post the results of clinical trials on ClinicalTrials.gov or other publicly accessible 
websites, as required by Takeda Policy/Standard, applicable laws and/or regulations.
15.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the Clinical Study Site Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this policy, he or 
she should contact the sponsor or sponsor’s designee.

Footnotes:
Day=day after the first dose. AVA=anti-vedolizumab antibodies, HBV=hepatitis B virus, HCV=hepatitis C virus, PK=pharmacokinetics, PML=progressive multifocal 
leukoencephalopathy. 
Week 6A: Subjects will receive the clinical and endoscopical evaluation for Complete Mayo score determination at Week 6 (-5 days), as close as possible to the beginning of this 
evaluation period. Endoscopy subscore will be determined by central reading prior to Visit Week 6 (+3days).
Week 6B: Subjects who achieved clinical response (by Complete Mayo Score) will be randomized to receive vedolizumab blinded SC/IV/Placebo. Except for Non-Responders (NR 
by Complete Mayo Score) at Week 6 who will received a 3rd dose of open-label vedolizumab IV and be assessed at Week 14 for response (by partial Mayo Score).
(a) All Baseline (Week 0) assessments will be done pre-vedolizumab IV.
(b) Week 6a visit should be performed between Day 38 and 43 (inclusive) and Week 6b visit should be performed between Day 43 and 46 (inclusive). The Week 6a and 6b visits 
should not be performed on the same day.
(c) Physical examination: Clinically significant findings will be recorded as concurrent conditions if start prior to signing the informed consent, or as PTEs if start after signing of the 
informed consent and as AEs if starts after the first dose of study drug.
(d) Vital signs: Height (cm) and weight (kg; without shoes) will be measured during Screening. Weight and vital signs will also be measured on clinic dosing days prior to dosing.
(e) 
 
(f) Diary review: will be administered prior to each dosing event either in person at dosing occurring in the clinic during scheduled visits or over the phone when the subject is 
injecting outside of the clinic.
(g) Concomitant medications and procedures: Monitoring will begin at signing of the informed consent.
(h) The components of the Complete Mayo score to determine eligibility at Week 0 must be completed within 10 days prior to receiving the first dose of study drug. The components 
of the partial Mayo score are stool frequency, rectal bleeding, and physician rating of disease activity.
(i) Indicates Complete Mayo score calculation.
(j) Flexi-sigmoidoscopy: The endoscopy will be performed prior to Week 0 to assess eligibility for Enrollment and at Week 6a to assess eligibility for Randomization at Week 6b. 
Then at Wk52 or ET.
(k) Colonic tissue samples will be collected during each colonoscopy for histological analysis. The tissue samples taken for each collection timepoint for histology will be sub-divided 
prior to fixing for PGx tissue analysis if consented to by the subject.
(l) Week 0 and 2 dosing will be done with vedolizumab IV; from Week 6 randomization, dosing will be done with vedolizumab blinded SC/IV/Placebo. Non-Responders (NR by 
Complete Mayo Score) at Week 6 will received a 3rd dose of open-label vedolizumab IV and be assessed at Week 14 for response (by partial Mayo Score). Responders at Week 14 
will be assessed for eligible for the Open-Label Extension (OLE) study. Non-Responders at Week 14 will be discontinued and returned to routine medical care.
(m) PTEs will be captured immediately following the signing of the informed consent at Screening, up until the first dose of study drug. Collection of AEs, to include concomitant 
medications, will begin following first dose of study drug and will continue through Week 68/Final Safety Visit. To be performed in person at dosing occurring in the clinic during 
scheduled visits. 
(n) Collection of all SAEs will begin once the informed consent is signed and will continue through Week 68/ Final Safety Visit. To be performed in person at dosing occurring in the 
clinic during scheduled visits. 
(o) All females of child bearing potential must have a serum pregnancy test at Screening and WK52/ET and Final Safety Visit. A urine pregnancy test will be completed for all 
females of child bearing potential prior to each dose of study drug injected during clinic visits. 
(p) Follicle-stimulating hormone (FSH) level will be obtained for female subjects at Screening if they are postmenopausal by history (ie, last regular menstrual cycle >1 years) and not 
surgically sterile. The FSH result must be >40 IU/L for the subject to be permitted not to use adequate contraception.
(q) All PK and AVA samples will be obtained at predose (within 30 minutes prior to dosing). 
(r) Fecal calprotectin stool sample should be the first bowel movement on the day of collection.
(s) A stool sample for culture, ova and parasite evaluation, and C. difficile assay will be obtained (if indicated) at Screening and at any time point during the study when a subject 
becomes symptomatic, including worsening or return of disease activity.

Appendix E
Collection, Shipment, and Storage of Pharmacogenomic Samples 
Sample Collection
Collect two whole blood samples (3 mL per sample) for deoxyribonucleic acid (DNA) isolation 
will be collected before dosing on Day 1 from each subject in the study, into plastic K2 
ethylenediamine-tetraacetic acid (EDTA) spray-coated tubes.
If necessary and feasible, a second aliquot of blood may be taken if isolation of DNA from the first 
sample was not successful or possible. Collect two whole blood samples (2.5 mL per sample) will 
be collected at each time point at predose on Day 1 for RNA pharmacogenomic analysis from each 
subject in the study, into a PaxGeneTM tube.
For detailed instructions on sample collection and storage follow the laboratory manual provided 
by the central laboratory.
Sample Shipment
Ship samples only on Monday, Tuesday, or Wednesday, and at least 2 days prior to a national 
holiday, to minimize the possibility of samples in transit over a weekend or holiday. The 
laboratory must confirm arrival of the shipped samples.
For instructions on shipping and packing follow the laboratory manual and shipping instructions 
provided by the central laboratory.
Before shipping, ensure the sample tubes are tightly sealed.
Sample Storage
The DNA and RNA samples will be stored in a secure storage space with adequate measures to 
protect confidentiality. The samples will be retained while research on vedolizumab continues for 
up to but not longer than 15 years or as required by applicable law.
For Japan, please refer to the appropriate study manual provided separately for additional

Mayo Scoring System for the Assessment of Ulcerative Colitis Activity
Category (a)
Stool frequency (b)
0 = Normal no. of stools for this patient
1 = 1 to 2 stools more than normal
2 = 3 to 4 stools more than normal
3 = 5 or more stools more than normal
Sub score, 0 to 3
Rectal bleeding (c)
0 = No blood seen 
1 = Streaks of blood with stool less than half the time 
2 = Obvious blood with stool most of the time 
3 = Blood alone passes 
Sub score, 0 to 3
Findings on endoscopy 
0 = Normal or inactive disease 
1 = Mild disease (erythema, decreased vascular pattern, mild friability)
2 = Moderate disease (marked erythema, lack of vascular pattern, friability, erosions)
3 = Severe disease (spontaneous bleeding, ulceration)
Sub score, 0 to 3; 0 = Normal or inactive disease
Physician’s global assessment (d)
0 = Normal
1 = Mild disease
2 = Moderate disease
3 = Severe disease
Sub score, 0 to 3
(a) The Mayo score ranges from 012, with higher scores indicating more severe disease. Partial Mayo score excludes 
endoscopy and ranges from 09.
(b) Each patient serves as his or her own control to establish the degree of abnormality of the stool frequency.
(c) The daily bleeding score represents the most severe bleeding of the day.
(d) The physician’s global assessment acknowledges the 3 other criteria, the patient’s daily recollection of abdominal 
discomfort and general sense of well-being, and other observations, such as physical findings and the patient’s 
performance status.
