Primary Objective:

To compare the PK of single dose of vedolizumab SC 108 mg administered as PFS vs PFS+AI.
Subject Population: Healthy men and women (nonpregnant and nonlactating). 
Number of Subjects:
Per dose group: 12
Estimated Total: 24 randomized
Number of Sites: 
Estimated total: 1 site in the United States
Dose Level(s):
Single dose of vedolizumab SC 108 mg 
Route of Administration:
SC injection
Duration of Treatment:
Subject will receive on Day 1 a single dose of vedolizumab 
SC 108 mg
Period of Evaluation:
196 days including Screening Period 
Main Criteria for Inclusion:
Healthy male and female (nonpregnant, nonlactating) subjects aged 18 to 65 years inclusive, with a body mass index 
from 18 to 28 kg/m² or a body weight >50 kg and <90 kg.
Main Criteria for Exclusion:

The subject has received any investigational or approved biologic or biosimilar within 30 days or 5 half-lives, of 
Screening, whichever is longer. 

The subject has had prior exposure to vedolizumab, or has hypersensitivity to vedolizumab or any of its 
components.

The subject has had previous exposure to approved or investigational anti-integrins (eg, natalizumab, efalizumab, 
etrolizumab, AMG 181) or anti-mucosal addressin cell adhesion molecule-1 (MAdCAM-1) antibodies or 
rituximab. 

Subjects with ≥1 positive responses on the PML subjective symptom checklist at Screening or before dosing on 
Day 1.

Subjects with active or latent tuberculosis, regardless of treatment history.
Main Criteria for Evaluation and Analyses:
PK:
Blood samples (5 mL) will be collected for the determination of serum vedolizumab concentrations at the following 
times: predose (within 30 minutes before the start of SC dosing), 2, 8, 24, 72, 120, and 168 hours after Day 1 dosing, 
and on Days 10, 15, 29, 43, 64, 85, 106, and Final Visit Day 127/Early Termination.
The following serum PK parameters for vedolizumab SC will be analyzed as primary PK endpoints for each 
presentation: maximum observed serum concentration (Cmax), area under the serum concentration-time curve from 
time 0 to time of the last quantifiable concentration (AUClast), area under the serum concentration-time curve from 
time 0 to infinity (AUC∞). Additional PK endpoints include area under the serum concentration-time curve from time 
0 to Week 2 (AUCWeek 2), time of first occurrence of Cmax, and terminal disposition phase half-life. 
Safety:
The following safety variables will be used to characterize the safety and tolerability of vedolizumab SC: physical 
examination findings, treatment-emergent adverse events, clinical laboratory test results (clinical chemistry, 
hematology, urinalysis), vital sign measurements, and 12-lead electrocardiogram. Percentage of subjects who are 
positive for antivedolizumab antibodies (AVA) and/or neutralizing AVA. 
Statistical Considerations:
PK:
For summary statistics and median plots by sampling time, the nominal PK sampling time will be used; for individual 
subject plots by time, the actual PK sampling time will be used.
The PK parameters will be summarized descriptively by treatment within each treatment. For AUCWeek 2, AUClast, 

Vedolizumab SC
Study No. VedolizumabSC-1021

Protocol 
11 December 2017
CONFIDENTIAL
AUC∞, and Cmax, individual subject parameters will be plotted by treatment. 
Natural log transformed AUCWeek 2, AUC∞(if data permit), AUClast, and Cmax will be analyzed using an analysis of 
covariance model with treatment as a fixed effect and weight as a continuous covariate. Estimates of the adjusted mean 
differences (Test-Reference) and corresponding 90% CIs will be obtained from the model. The adjusted mean 
differences and 90% CIs for the differences will be exponentiated to provide estimates of the ratio of adjusted 
geometric means (Test/Reference) and 90% CIs for the ratios. Single doses of 108 mg of vedolizumab administered as 
PFS (reference treatment) will be compared vs PFS+AI (Test Treatment). 
Sample Size Justification: 
The sample size of 12 subjects per group is considered to be sufficient for exploratory purposes. The study is not 
powered for statistical hypothesis testing.

INTRODUCTION
4.1
Background
Vedolizumab (also known as MLN0002, ENTYVIO, or KYNTELES) is a recombinant
humanized monoclonal antibody (mAb) composed of 2 light chains of the subclass and 
2 immunoglobulin G1 heavy chains that binds specifically to the human lymphocyte integrin 47. 
The 47 integrin is a pivotal mediator of gut immunity and inflammation because of its unique 
role in mediating the migration of lymphocytes into gut-associated lymphoid tissue and lamina 
propria, via binding to mucosal addressin cell adhesion molecule-1 (MAdCAM-1). Thus, 
vedolizumab acts as a gut-selective immunomodulator. 
Vedolizumab intravenous (IV) has been developed as a treatment for ulcerative colitis (UC) and 
Crohn’s disease (CD), which are characterized by inflammation of the gastrointestinal tract. 
Marketing approval has been granted in the United States, European Union, and multiple other 
countries for the treatment of adult patients with moderately to severely active UC or CD who have 
failed conventional therapy (ie, corticosteroids or immunomodulators) or tumor necrosis factor 
alpha antagonists. 
Two presentations of vedolizumab have been developed: a lyophilized powder for IV infusion and 
a liquid for subcutaneous (SC) injection. Vedolizumab SC (also known as Vedolizumab Injection, 
for Subcutaneous Use; Vedolizumab Solution for Injection in Prefilled Syringe; or MLN0002 SC) 
is a liquid presentation that has been developed for SC administration. To develop vedolizumab 
SC, the vedolizumab IV presentation was modified to ensure the long-term stability needed for a 
liquid product. However, the vedolizumab SC drug product presentation is similar to that of the 
vedolizumab IV presentation after reconstitution. No changes were made that would impact the 
primary structure of the protein, and comparable biochemical properties and in vitro functional 
activity have been demonstrated. Therefore, the nonclinical and clinical information from studies 
with vedolizumab IV are considered relevant.
The bioavailability, pharmacokinetics (PK), and safety 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 estimate from vedolizumab SC was 75.1%. The SC bioavailability was 
independent of the SC doses evaluated (54, 108, and 160 mg vedolizumab SC). All other PK 
parameters estimates were very similar to the values derived from phase 3 data with vedolizumab 
IV, and there were no PK differences by race (Japanese vs non-Japanese). In study 
MLN0002SC_101, 75.0% of subjects (36 of 48 subjects) had treatment-emergent adverse events 
(TEAEs). The percentage of subjects with a TEAE was the same when comparing subjects who 
received vedolizumab SC and 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. Four subjects had persistently moderate to high antivedolizumab antibodies (AVA) titers

for ≥14 weeks with an impact on PK; these subjects were excluded from population PK analysis 
and were not included in the noncompartmental PK summaries. Overall, vedolizumab SC and 
vedolizumab IV were well tolerated in this study. The observed TEAEs were consistent with the 
overall safety profile of vedolizumab.
Previously conducted clinical studies have characterized the efficacy, safety, tolerability, PK, 
pharmacodynamics, and immunogenicity of vedolizumab IV, a lyophilized formulation. As of 
19 November 2016, vedolizumab exposure has extended for ≥12 months in 1832 subjects, 
≥24 months in 1379 subjects, ≥36 months in 1169 subjects, ≥48 months in 862 subjects, 
≥60 months in 645 subjects, ≥72 months in 308 subjects, ≥84 months in 32 subjects, and 
≥96 months in 22 subjects. Based on the most recent drug shipment data (19 November 2016), the 
cumulative patient exposure to vedolizumab IV since its marketing approval in May 2014 is 
estimated to be approximately 77,382 patient-years.
4.2
Rationale for the Proposed Study
IV infusion may not be convenient as long-term therapy, vedolizumab SC has been developed to 
ultimately enable injection of vedolizumab by patients or their caregivers. The safety and efficacy 
of this formulation is currently being investigated in ongoing phase 3 studies in adults with 
moderately to severely active UC or CD who achieved clinical response following open-label 
vedolizumab IV therapy (MLN0002SC-3027 and MLN0002SC-3031). The current presentation 
of the SC formulation is in a prefilled syringe. 
The purpose of this phase 1 clinical study is to assess the PK, and variability of a vedolizumab SC 
108 mg dose in a prefilled syringe (PFS) vs prefilled syringe in autoinjector (PFS+AI). The 
PFS+AI presentation is planned to be the commercially available device after approval.
The information collected in this study will be used to calculate the sample size in study 
VedolizumabSC-1022. 
4.3
Benefit/Risk Profile 
The proposed study (VedolizumabSC-1021) is designed to evaluate the PK and variability of a 
vedolizumab SC 108 mg dose in a PFS vs PFS+AI. No changes were made to the vedolizumab SC 
drug product composition that would impact the primary structure of the protein, and comparable 
biochemical properties and in vitro functional activity have been demonstrated. Therefore, the 
nonclinical and clinical information from studies with vedolizumab IV are considered relevant.
The safety of the vedolizumab SC presentation is expected to be similar to that of vedolizumab IV 
because of similar exposure, outside of expected local administration site events, such as 
injection-site reactions. The observed adverse events (AEs) with vedolizumab SC are consistent 
with the vedolizumab IV safety profile in ongoing phase 3 clinical studies.
A phase 1 single dose study with the SC formulation in health volunteers was conducted and 
identified no safety concerns. This study is comparing different devices and the safety is expected 
to be similar among these devices.

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is an open-label, randomized, parallel-group study to compare the PK of a single dose of 
vedolizumab SC 108 mg for injection administered in 2 different device delivery presentations in 
healthy subjects. A minimum of 24 subjects (12 per group) will be randomized to 1 of 2 device 
presentations (Group A or B).
A summary of the treatment groups is presented in Table 6.a.

Single dose of vedolizumab SC 108 mg delivered by PFS+AI (test).
(a) Subjects randomized to each device will also be randomized for the site of administration (abdomen, thigh, or arm). 
Thus, within each treatment group, there are 3 sites of administration (abdomen, thigh, or arm) randomly assigned, for 
a total of 6 treatment combinations.
Subjects will be screened up to 28 days to determine eligibility before randomization. Eligible 
subjects will return to the clinic at Check-in (Day -1). On Day 1, all doses will be administered by
a health care professional. A schematic of the study design is included as Figure 6.a. A schedule of 
assessments is listed in Appendix A.

(b) Subjects will be followed poststudy by telephone to administer a questionnaire, which will include progressive 
multifocal leukoencephalopathy (PML) questions at Day 168 (±3 days). 
Subjects for all treatments groups will be kept in the study unit from Day -1 Check-in until at least 
24 hours after dosing (Day 2) for safety and PK assessment before discharge. The minimum 
confinement will be 2 nights (Days -1 to 2, inclusive). Subjects can stay longer at the discretion of 
the investigator. Subjects will return to the study units periodically according to the schedule for 
PK sampling and safety assessments. Subjects will be required to participate in a long-term 
follow-up (LTFU) safety survey by telephone on Day 168. 
At least 40% of each sex group will be enrolled.

6.2
Justification for Study Design, Dose, and Endpoints
This study is designed in accordance with Food and Drug Administration (FDA) Guidance 
documents [1,2]. The primary PK endpoints Cmax and area under the serum concentration-time 
curve are standard parameters to compare the rate and extent of absorption.
This study will be performed in healthy subjects, rather than the target subject population (ie, 
patients with UC or CD) because of the potential for immunogenicity in subjects after single dose 
administration. Similar PK has been observed in healthy subjects and patients with UC or CD 
following administration of vedolizumab IV.
The study design is open-label, since the primary objective is to assess objective variables, that is, 
vedolizumab PK using multiple device presentations. Because this is an objective measurement, 
there is consequently no risk of potential bias of the study results; hence, neither study blinding nor 
inclusion of a placebo group is required. 
Vedolizumab is a mAb with a long half-life that precludes a crossover design. Therefore, a parallel 
design will be used.
Vedolizumab SC dose of 108 mg was selected for this study as it is the dose being tested in phase 3 
vedolizumab SC studies.
AEs, vital signs, weight, ECG findings, and laboratory test results are commonly used safety 
endpoints.

precedence followed by the blood draw and then the meal. 
7.5
Criteria for Discontinuation or Withdrawal of a Subject
The primary reason for discontinuation or withdrawal of the subject from the study or study drug 
should be recorded in the case report form (CRF) using the following categories. For screen failure 
subjects, refer to Section 9.1.15.
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.


Liver Function Test (LFT) Abnormalities
Study drug 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 9.1.8), if the following circumstances occur at any time 
during study drug 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 drug 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. Attempts to contact the subject must be documented in the subject’s source 
documentation.
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 
CRF.
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 because of 
an AE 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 9.1.10.
7. Other.
Note: The specific reasons should be recorded in the “specify” field of the CRF.
7.6
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 7.5. 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

6 treatment combinations total.
Detailed instructions for SC administration of vedolizumab with the PFS and PFS+AI will be 
provided to the study site(s) in a separate Instructions for Use and Medication Guide.
8.1.4
Overdose
An overdose is defined as a known deliberate or accidental administration of study drug, to or by a 
study subject, at a dose above that which is assigned to that individual subject according to the 
study protocol.
Cases of overdose without manifested signs or symptoms are not considered AEs. AEs associated 
with an overdose will be documented on AE CRF(s) according to Section 10.0.
Serious adverse events (SAEs) associated with overdose should be reported according to the 
procedure outlined in Section 10.2.2.
In the event of drug overdose, the subject should be treated symptomatically.
8.2
Study Drug Assignment and Dispensing Procedures
Subjects will be assigned, in the order in which they are randomized into the study, to receive their 
treatment according to the randomization schedule allocated to the site. The randomization 
sequence number will be entered onto the CRF.
Subjects will be assigned to receive a 4-digit randomization sequence number on Day 1. The 
number will be assigned by the clinic site personnel in sequential order. There will be equal 
assignment of the subjects to 1 of the 6 possible combinations of 2 treatments and 3 administration 
sites. Male subjects will be assigned a randomization sequence number in ascending order; female 
subjects will be assigned a randomization sequence number in descending order. 
This 4-digit number will be used by the clinical site to facilitate the prelabeling of PK samples, and

Randomization Code Creation and Storage 
The final randomization list will be created, reviewed, and approved by Celerion Randomization 
and Unblinding Administrators who are not members of the study team. After the final 
randomization lists have been approved, the randomization lists will be transferred to the Celerion
Pharmacy and kept in a restricted area to which only the Celerion Pharmacy staff has access.
8.4
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 investigator or designee 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, the investigator or designee must maintain 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.
Upon receipt of sponsor-supplied drug, the investigator or designee 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, investigator or designee 
should acknowledge the receipt of the shipment by signing bottom half of the packing list and 
faxing per instructions provided on the form. If there are any discrepancies between the packing 
list versus 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.
The investigator or designee must maintain 100% accountability for all sponsor-supplied drugs 
received and dispensed during his or her entire participation in the study. 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 lot/medication identification/job number used to 
prepare each dose.

Verifying that all containers used 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 investigator or designee 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 

Vedolizumab SC

of sponsor-supplied drugs, expiry and/or retest date, date and amount dispensed, including initials, 
seal, or signature of the person dispensing the drug, and the date and amount returned to the site by 
the subject, including the initials, seal, or signature of the person receiving the sponsor-supplied 
drug. The log should include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.
All used devices must be returned intact (not destroyed) to Takeda or designee.
Before site closure or at appropriate intervals, a 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 investigator or designee will retain a 
copy of the documentation regarding sponsor-supplied drug accountability, return, and originals 
will be sent to the sponsor or designee.
The investigator will be notified of any expiry date or retest date extension of sponsor-supplied 
drug during the study conduct. On expiry date notification from the sponsor or designee, the site 
must complete all instructions outlined in the notification, including segregation of expired 
sponsor-supplied drug for return to the sponsor or its designee for destruction.
In the event of expiry date extension of supplies already at the study site, sponsor-supplied drugs 
may be relabeled with the new expiry date at that site. In such cases, Takeda or its designee will 
prepare additional labels, certificates of analyses, and all necessary documentation for completion 
of the procedure at the sites.
The on-site pharmacist (the site designee) will immediately return unused study drugs to the 
sponsor after the study is closed at the study site.

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 before the subject entering into the study, and before any 
protocol-directed procedures are performed, including requesting that a subject fast for laboratory 
evaluations.
A unique subject identification number (subject number – site + subject number) will be assigned 
to each subject at the time that informed consent is obtained; this subject number will be used 
throughout the study.
9.1.2
Demographics, Medical History, and Medication History Procedure
Demographic information to be obtained will include date of birth, sex, Hispanic ethnicity, race as 
described by the subject, alcohol use, 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 resolved at or before signing of 
informed consent. Ongoing conditions are considered concurrent medical conditions (see 
Section 9.1.7).
Medication history information to be obtained includes any medication relevant to eligibility 
criteria stopped at or within 14 days before signing of informed consent.
9.1.3
Physical Examination Procedure
A baseline physical examination (defined as the assessment before first dose of study 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; and (11) other.
Any abnormal finding on a pretreatment physical examination assessment must be assessed as not 
clinically significant or clinically significant by the investigator and recorded in the source 
document and CRF. All clinically significant findings/changes will be recorded as a PTE or 
concurrent medical condition in the source document and on the appropriate CRF described in 
Section 10.0 or Section 9.1.7.
On subsequent examinations, any abnormal change from the pretreatment physical examination 
assessment occurring immediately before the start of the study drug must be assessed as not 
clinically significant or clinically significant by the investigator and recorded in the source 

Vedolizumab SC

document and CRF. Any clinically significant change or new diagnosis as a result of a clinically 
significant change, as determined by the investigator, will be recorded as an AE in source 
documentation and on the PTE/AE CRF described in Section 10.0. 
9.1.4
Weight, Height, and BMI
Body weight and height will be obtained with the subject’s shoes off and jacket or coat removed. 
BMI equals a person’s weight in kilograms divided by height in meters squared (BMI=kg/m2). 
BMI will be rounded to the nearest whole number according to the standard convention of 0.1 to 
0.4 rounded down and 0.5 to 0.9 rounded up.
9.1.5
Vital Sign Procedure
Vital signs will include body temperature (oral measurement), respiratory rate, sitting/standing
blood pressure (systolic and diastolic, resting more than 5 minutes), and pulse (beats per minute).
Vital signs (oral temperature, respiration, pulse, and blood pressure) will be obtained at Screening, 
Check-in (Day -1), Day 1 (predose, postdose), Days 8, 106±3, and Final Visit Day 127±3/Early 
Termination. For Day 1, heart rate and blood pressure will be measured after 5 minutes in the 
supine position and at 1 and 3 minutes after standing. For Days 8, 106±3, and 127±3/Early 
Termination, heart rate and blood pressure will be measured after 5 minutes supine only. 
All measurements will be recorded on the source documents and in the CRF. 
Vital signs should be measured at the same time of the day across visits if possible. Beginning on 
Day 1, when vital signs are scheduled at the same time as blood draws, vital signs will take priority 
and will be obtained approximately 5 minutes before the scheduled blood draw. 
9.1.6
Documentation of Concomitant Medications
Concomitant medication is any drug given in addition to the study drug. These may be prescribed 
by a physician or obtained by the subject over the counter. Concomitant medication is not provided 
by the sponsor. At each study visit, subjects will be asked whether they have taken any medication 
other than the study drug (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 CRF. Documentation will include generic medication name, 
dose, unit, frequency, route of administration, start and end dates, and reason for use. 
9.1.7
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 examination, according to the judgment of the 
investigator. The condition (ie, diagnosis) should be described.

The local laboratory will perform laboratory tests for hematology, serum chemistries, and 
urinalysis. The results of laboratory tests will be returned to the investigator, who is responsible for 
reviewing and filing these results.
If subjects experience ALT or AST >3×ULN, follow-up laboratory tests (at a minimum, serum 
alkaline phosphatase, ALT, AST, total bilirubin, GGT, and INR) should be performed within a 
maximum of 7 days and preferably within 48 to 72 hours after the abnormality was noted. (Refer to 
Section 7.5 and Section 10.2.3 for the appropriate guidance on reporting abnormal liver function 
tests.)
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 drug, 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
for reporting requirements).
All laboratory safety data will be transferred electronically to Takeda or designee in the format 
requested by Takeda. If the laboratory is unable to electronically transfer data, the investigator or 
designee is responsible for transcribing or attaching laboratory results to the CRF. The investigator 
will maintain a copy of the laboratory accreditation and the reference ranges for the laboratory 
used.
Laboratory reports must be signed and dated by the principal investigator or designee indicating 
that the report has been reviewed and any abnormalities have been assessed for clinical 
significance. Any abnormalities identified before the first dose will require clear and complete
documentation in the source documents as to the investigator’s assessment of not clinically 
significant before proceeding with enrollment/randomization.
All clinically significant laboratory abnormalities must be recorded as a PTE/AE in the subject’s 
source documents and on the appropriate CRF. A clinically significant laboratory abnormality that 
has been verified by retesting will be followed until the abnormality returns to an acceptable level 
or a satisfactory explanation has been obtained.

Contraception and Pregnancy Avoidance Procedure
9.1.9.1
Male Subjects and Their Female Partners
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study drug, 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. 
9.1.9.2
Female Subjects and Their Male Partners
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study drug, female subjects of childbearing potential* who are sexually active with a

nonsterilized male partner** must use a highly effective method of contraception (from the list 
below).
In addition they must be advised not to donate ova during this period.
9.1.9.3
Definitions and Procedures for Contraception and Pregnancy Avoidance
The following definitions apply for contraception and pregnancy avoidance procedures.
* A woman is considered a woman of childbearing potential, that is, fertile, following menarche 
and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods 
include hysterectomy, and bilateral oophorectomy. A postmenopausal state is defined as no 
menses for 12 months without an alternative medical cause. A high FSH level in the 
postmenopausal range (FSH >40 IU/L) may be used to confirm a postmenopausal state in younger 
women (eg, those <45 years old) or women who are not using hormonal contraception or hormonal 
replacement therapy. However, in the absence of 12 months of amenorrhea, a single FSH 
measurement is insufficient.
** Sterilized men should be at least 1 year post–bilateral vasectomy and have confirmed that they 
have obtained documentation of the absence of sperm in the ejaculate or have had bilateral 
orchidectomy.
The following procedures apply for contraception and pregnancy avoidance.
1. Highly effective methods of contraception are defined as “those, alone or in combination, that 
result in a low failure rate (ie, less than 1% failure rate per year when used consistently and 
correctly). In this study, where medications and devices containing hormones are included, the 
acceptable methods of contraception are: 

Nonhormonal Methods: 
–
Intrauterine device. 
–
Bilateral tubal occlusion. 
–
Vasectomized partner (provided that partner is the sole sexual partner of the study
participant and that the vasectomized partner has received medical assessment of the 
surgical success. 
–
True sexual abstinence, only if this is in line with the preferred and usual lifestyle of the 
subject. True abstinence is defined as refraining from heterosexual intercourse during 
the entire period of the study, from 1 month before the first dose until 18 weeks after
last dose.

Hormonal Methods: Hormonal contraception may be susceptible to interaction with the 
investigative compound, comparator, concomitant medications, which may reduce the 
efficacy of the contraception method.
–
Combined (estrogen and progestogen) hormonal contraception associated with 
inhibition of ovulation initiated at least 3 months before the first dose of study drug OR 

Vedolizumab SC
Study No. VedolizumabSC-1021
Page 38 of 74
Protocol 
11 December 2017
CONFIDENTIAL
combined with a barrier method (male condom, female condom or diaphragm) if for 
shorter duration until she has been on contraceptive for 3 months:

Oral. 

Intravaginal (eg, ring).

Transdermal. 
–
Progestogen-only hormonal contraception associated with inhibition of ovulation 
initiated at least 3 months before the first dose of study drug OR combined with a 
barrier method (male condom, female condom or diaphragm) if shorter till she has been 
on contraceptive for 3 months:

Oral. 

Injectable.

Implantable.
2. Subjects will be provided with information on highly effective 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.
3. During the course of the study, regular serum hCG pregnancy tests will be performed only for 
women of childbearing potential and all subjects (male and female) will receive continued 
guidance with respect to the avoidance of pregnancy and sperm donation as part of the study 
procedures. Such guidance should include a reminder of the following:
a) Contraceptive requirements of the study.
b) Reasons for use of barrier methods (ie, condom) in males with pregnant partners.
c) Assessment of subject compliance through questions such as
i. Have you used the contraception consistently and correctly since the last visit?
ii. Have you forgotten to use contraception since the last visit?
iii. Are your menses late (even in women with irregular or infrequent menstrual cycles a 
pregnancy test must be performed if the answer is “yes”)
iv. Is there a chance you could be pregnant?
4. In addition to a negative serum hCG pregnancy test at Screening, female subjects of 
childbearing potential must also have confirmed menses in the month before first dosing (no 
delayed menses), a negative serum hCG pregnancy test as close as possible and before first 
dose of study medication, preferably on the same day.

9.1.10
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. 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 drug, for example, after Day 1 or 
within 18 weeks of the last dose of active study drug, the pregnancy should be reported 
immediately, using a pregnancy notification form, to the contact listed in Section 1.0.
If the female subject and/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 female 
subject/female partner of the subject was participating in a clinical study at the time she became 
pregnant and provide details of the study drug the subject received (blinded or unblinded, as 
applicable).
All reported pregnancies, including female partners of male subjects, 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.
9.1.11
ECG Procedure
Standard 12-lead ECGs will be recorded at Screening, Check-in (Day -1), Day 1 (predose [within 
0.5 hours before dosing the SC injection]), Day 8, and Final Visit Day 127/Early Termination. 
When an ECG recording is scheduled for the same day as blood draws (eg, PK or AVA sampling), 
the ECG recording will be collected 5 minutes before the nominal time of the blood sample.
Additional unscheduled ECGs may be recorded where clinically necessary for subject safety.
ECGs will be read automatically and also, the investigator or subinvestigator will manually 
interpret the ECG using 1 of the following categories: within normal limits, abnormal but not 
clinically significant, or abnormal and clinically significant. All 12-lead ECGs will be stored for 
manual measurement of intervals, if necessary. Twelve-lead ECGs will be recorded using an ECG 
machine that automatically calculates the heart rate and measures PR interval, RR interval, QRS 
interval, QT interval, QT interval with Fridericia correction method, and QT interval with Bazett 
correction method intervals. Paper ECG traces will be recorded for 10 seconds at a standard paper 
speed of 25 mm/sec and gain of 10 m/mV or digital recordings will be used.
One copy of the 12-lead ECG with the physician’s signature and date of assessment will be filed 
with the source documents and captured in the appropriate CRF. If the original ECG is printed on 
thermal paper, the ECG report must be photocopied and certified. The photocopy will be filed with 
the original ECG in source.
9.1.12
Immunogenicity Sample Collection 
Blood specimens for the assessment of AVA will be collected as shown in the Schedule of Study 
Procedures (Appendix A). A sample will be assessed for neutralizing AVA if AVA is detected. If

All subjects will complete TB screening to determine eligibility. All subjects must complete a 
diagnostic during Screening. Subjects will be excluded from the study if they have active or latent 
TB, regardless of treatment history, as defined in Section 7.2.
9.1.16 PML Checklist, Wallet Card, and Follow-up Phone call
Clinic staff will administer the subject PML checklist during Screening to exclude subjects with 
positive responses from enrolling into the study. The PML subjective checklist will be 
administered at Screening Visit, on Day 1 before dose, Day 127 (±3)/Early Termination Visit, and 
at any unscheduled visits.
A wallet card that denotes key study information, including signs and symptoms of PML, will be 
distributed to all subjects during Screening.
Upon completion or early termination from the study, all subjects will be required to participate by 
telephone in a LTFU safety survey on Day 168. A questionnaire will be administered and will 
include PML and neurological symptom question. Any subjects reporting signs and/or symptoms 
of PML will undergo objective testing and may be referred to a neurologist for a full evaluation, as 
described in the Risk Assessment and Minimization for PML (RAMP) algorithm. The PML 
checklists and the RAMP algorithm and tools are included in a separate manual. All confirmed 
cases of PML will be recorded as SAEs.
9.1.17 Pain Scale Assessment
The Visual Numeric Scale (VNS) [3] for self-reported pain assessment at the injection site will be 
completed by each subject. The VNS will be completed on Day 1 immediately following the SC 
injection and a second assessment will be performed between 15 and 30 minutes following the 
injection. Subjects will be presented with the pain scale and instructed to assess their pain on a 
scale of 0 to 10, with 0=no pain and 10=severe pain.

Documentation of Screen Failure
Investigators must account for all subjects who sign informed consent. If a subject is withdrawn at 
the screening visit, the investigator should complete the CRF screen failure form.
The primary reason for screen failure is recorded in the CRF using the following categories:

PTE/AE.

Screen failure (did not meet entrance criteria).

Protocol deviation.

Lost to follow-up.

Withdrawal by subject.

Study terminated by sponsor.

Death.
Subject identification numbers assigned to subjects who fail screening should not be reused. If a 
subject fails screening, but is later successfully rescreened, the data for the subject will be entered 
as if these were 2 separate subjects. Therefore the data should be entered as follows:
1. The screen failure data should be entered as a screen failure subject.
2. Rescreened subjects should be assigned a new subject number and treated as a stand-alone 
subject.
9.1.19
Documentation of Randomization
Only subjects who meet all of the inclusion criteria and none of the exclusion criteria are eligible 
for randomization into the treatment phase.
If the subject is found to be not eligible for randomization, the investigator should record the 
primary reason for failure on the applicable CRF.
9.2
Monitoring Subject Treatment Compliance
Study medication will be administered by a health care professional while subjects are under 
observation in the clinical research unit. The date and time of each dose will be recorded in the 
source documents and on the CRFs. An inventory of the study drug supplies dispensed will be 
performed by the site pharmacist or authorized study designee and recorded onto the Drug 
Accountability Log in the subject’s source document records or equivalent. The exact dose time of 
consecutive subjects may be staggered to facilitate logistics at the site.
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).

documenting Screening failures is provided in Section 9.1.18.
9.3.3
Final Visit or Early Termination
A Final Visit will be scheduled 127 (±3) days after the dose of study drug or at the Early 
Termination Visit. For all subjects receiving study drug, the investigator must complete the End of 
Study CRF page.
The reason for discontinuation must be documented in the source document and CRF. For all 
subjects receiving study medication, the investigator must complete the End of Study CRF page.

PRETREATMENT EVENTS AND ADVERSE EVENTS
10.1
Definitions
10.1.1
PTEs
A PTE is defined as any untoward medical occurrence in a clinical investigation subject who has 
signed informed consent to participate in a study but before administration of any study drug; 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 value), symptom, or disease temporally associated with the use of a drug whether or not 
it is considered related to the drug.
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 or 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 drug 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).
Laboratory values and ECG findings:

Changes in laboratory values or ECG findings 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 or ECG re-test and/or continued monitoring of an abnormal value or finding is not 

Vedolizumab SC
Study No. VedolizumabSC-1021
Page 46 of 74
Protocol 
11 December 2017
CONFIDENTIAL
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) should NOT be recorded as PTEs unless related 
to study procedures. However, if the subject experiences a worsening or complication of such a 
concurrent medical condition, the worsening or complication should be recorded appropriately 
as a PTE(worsening or complication occurs before start of study drug) or an AE (worsening or 
complication occurs after start of study drug). 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 concurrent medical condition (eg, asthma, epilepsy) any 
occurrence of an episode should only be captured as a PTE/AE if the condition becomes more 
frequent, serious or severe in nature. Investigators should ensure that the AE term recorded 
captures the change in the condition from Baseline (eg “worsening of…”).

If a subject has a pre-existing degenerative concurrent medical condition (eg, cataracts, 
rheumatoid arthritis), worsening of the condition should only be recorded as a PTE/AE if 
occurring to a greater extent to that which would be expected. 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 the start of study drug, 
the worsening or complication should be recorded 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 
drug, 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…”).
Changes in intensity of AEs/serious PTEs:

If the subject experiences changes in intensity of an AE/serious PTE, the event should be 
captured once with the maximum intensity recorded.
Preplanned surgeries or procedures:

Preplanned procedures (surgeries or therapies) that were scheduled before signing of informed 
consent are not considered PTEs or AEs. However, if a preplanned procedure is performed 
early (eg, as an emergency) because of a worsening of the pre-existing condition, the 

Vedolizumab SC
Study No. VedolizumabSC-1021
Page 47 of 74
Protocol 
11 December 2017
CONFIDENTIAL
worsening of the condition should be recorded 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.
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 CRF. Any 
manifested side effects will be considered PTEs or AEs and will be recorded on the AE page of 
the CRF.
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. Leads to 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).

Note: Terms identified on the Medically Significant AE List represent the broad medical concepts to be considered as 
“Important Medical Events” satisfying SAE reporting requirements.
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
AEs of Special Interest
An AE of Special Interest (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.
10.1.6
Intensity 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
Relationship of AEs to Study Drug(s)
The relationship (causality) of each AE to study drug(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 medications 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 medications 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 investigator.
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 Drug 

Drug withdrawn – a study drug is stopped because of the particular AE.

Dose not changed – the particular AE did not require stopping a study drug.

Unknown – only to be used if it has not been possible to determine what action has been taken.

Not applicable – a study drug was stopped for a reason other than the particular AE, eg, the 
study has been terminated, the subject died, dosing with study drug was already stopped before 
the onset of the AE.

Dose interrupted – the dose was interrupted because of the particular AE.

CONFIDENTIAL
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 1 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 because of hospital change or 
residence change at the end of the subject’s participation in the study.
10.2
Procedures
10.2.1
Collection and Reporting of AEs
10.2.1.1
PTE and AE Collection Period
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 drug (Day 1) or 
until screen failure. For subjects who discontinue before study drug 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 drug 
(Day 1). Routine collection of AEs will continue until the Final Visit (Day 127±3 days).
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. 
Nonserious PTEs, related or unrelated to the study procedure, need not to be followed-up for the 
purposes of the protocol.

11 December 2017
CONFIDENTIAL
All subjects experiencing AEs, whether considered associated with the use of the study drug 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 CRF, 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.
3. Frequency.
4. Intensity.
5. Investigator’s opinion of the causal relationship between the event and administration of study 
drug(s) (related or not related) (not completed for PTEs).
6. Investigator’s opinion of the causal relationship to study procedure(s), including the details of 
the suspected procedure.
7. Action concerning study drug (not applicable for PTEs).
8. Outcome of event.
9. Seriousness.
10.2.1.3
AEs of Special Interest
If these special interest AEs, which occur during the treatment period or the follow-up period, are 
considered to be clinically significant based on the criteria below, they should be recorded in a 
special interest AE CRF or an SAE form. The SAE form should be completed and reported to the 
SAE reporting contact in Section 1.0 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. 
Vedolizumab SC will be administered by a healthcare professional, who should be 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 during 
the SC administration and for 2 hours following completion of the administration. 
Subjects will be instructed to report the development of rash, hives, pruritus, flushing, urticaria, 
injection site pain, redness and/or swelling, etc, that may represent an administration-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. 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 Study Manual). 
Any injection site reaction will be collected and graded as follows:
Grade 1: Tenderness with or without associated symptoms (eg warmth, erythema, itching).
Grade 2: Pain, lipodystrophy, edema, phlebitis.
Grade 3: Ulceration or necrosis, severe tissue damage, operative intervention indicated.
Grade 4: Life threatening consequences; urgent intervention indicated.
Other 
Other special interest AEs include liver injury and PML, which are discussed in Sections 10.2.3
and 11.1.1, respectively.
The special interest AEs have to be recorded as AEs in the CRF. An evaluation form along with all 
other required documentation must be submitted to the sponsor.
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 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 drug(s).

Causality assessment.
The SAE form should be transmitted within 24 hours to the attention of the contact listed in 
Section 1.0. 
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.

10.2.3
Reporting of Abnormal LFTs
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 CRF 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 9.1.8 must also be performed. In addition, an LFT Increases CRF must 
be completed and transmitted with the Takeda SAE form (as per Section 10.2.1).
10.3
Follow-up of SAEs
If information is 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, 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 the 
study drug/sponsor supplied drug or that would be sufficient to consider changes in the study 
drug/sponsor supplied drug administration or in the overall conduct of the study. The study site 
also will forward a copy of all expedited reports to his or her IRB or IEC in accordance with local
regulations.

Adjudication Committee
A PML Independent Adjudication Committee (IAC) will be implemented for this study. The PML 
IAC will consist of a panel of leading PML experts, including a neurologist, neuroradiologist, and 
a virologist. 
11.1.1 Risk Assessment and Minimization for PML
To address the hypothetical risk of the development of PML in patients treated with vedolizumab, 
the sponsor, with input from renowned PML experts, has developed the RAMP program. The 
complete description of the RAMP program, including materials and instructions for its 
implementation and monitoring, is included in a separate manual. The RAMP is focused on early 
clinical detection and management of PML, including the discontinuation of study drug, if 
applicable. Subjects are assessed for signs and symptoms of PML before the administration of 
study drug using a PML subjective symptom checklist. Subjects with a positive PML subjective 
symptom checklist at any time after enrollment in a vedolizumab clinical study will be evaluated 
according to a prespecified algorithm (the PML Case Evaluation Algorithm). An IAC has been 
established as part of the RAMP program to review new neurological signs and symptoms 
potentially consistent with PML, and will provide input regarding patient evaluation and 
management as defined in the IAC charter.
To ensure the success of the RAMP program, site personnel will be trained to recognize the 
features of PML, and subjects will be trained to report specific neurological signs and symptoms 
without delay. Educational materials for teaching site personnel and patients about PML and the 
RAMP procedures will be distributed to the site. Formal teaching and training will be performed 
for site personnel before the start of the study. Subjects will receive training and educational 
materials before receiving treatment. The informed consent form will contain specific information 
on the hypothetical risk of PML. The PML IAC will be informed of all new neurological signs and 
symptoms potentially consistent with PML per the PML Case Evaluation Algorithm and will 
review the individual subject data. The algorithm and tools are included in the Study Manual. All 
documented cases of PML will be reported as SAEs, regardless of whether hospitalization occurs.

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 medical conditions will be coded using the Medical

Organization Drug Dictionary.
12.1
CRFs (Electronic and Paper)
Completed CRFs are required for each subject who signs an informed consent.
The sponsor or its designee will supply study sites with access to CRFs. The sponsor will make 
arrangements to train appropriate site staff in the use of the CRF. These forms are used to transmit 
the information collected in the performance of this study to the sponsor and regulatory authorities. 
CRFs must be completed in English. Data are transcribed directly onto CRFs.
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. Reasons for significant corrections should additionally be included.
The principal investigator must review the CRFs for completeness and accuracy and must e-sign 
the appropriate CRFs as indicated. Furthermore, the investigator must retain full responsibility for 
the accuracy and authenticity of all data entered on the CRFs.
CRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by the sponsor or its designee. 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 CRFs. The completed 
CRFs 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
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 CRFs, including the audit trail, and detailed records of drug disposition to 
enable evaluations or audits from regulatory authorities, the sponsor or its designees. Any source 
documentation printed on degradable thermal sensitive paper should be photocopied by the site 
and filed with the original in the subject’s chart to ensure long-term legibility. Furthermore, 
International Conference on Harmonisation (ICH) E6 Section 4.9.5 requires the investigator to 
retain essential documents specified in ICH E6 (Section 8) until at least 2 years after the last

13.1.1
Analysis Sets
Safety Set:
The safety analysis set will consist of all subjects who are enrolled and received 1 dose of study 
drug. Subjects in this analysis set will be used for demographic, baseline characteristics and safety 
summaries.
PK Set:
The PK set will consist of all subjects who receive study drug and have at least 1 measurable serum 
concentration.

Analysis of Demographics and Other Baseline Characteristics
Demographic and baseline characteristics will be summarized by treatment group. Summary 
statistics (number of subjects, mean, SD, median, minimum and maximum) will be generated for 
continuous variables (eg, age and weight) and the number and percentage of subjects within each 
category will be presented for categorical variables (eg, sex, ethnicity, and race). 
13.1.3
PK Analysis
Concentrations will be listed and summarized descriptively by PK sampling time. Summary will 
be done by treatment. Individual subject and median profiles of the concentration-time data will be 
plotted by treatment. For summary statistics and median plots by sampling time, the nominal PK 
sampling time will be used, for individual subject plots by time, the actual PK sampling time will 
be used.
PK parameters will be summarized descriptively by treatment. For AUCWeek 2, AUC∞, AUClast and 
Cmax, individual subject parameters will be plotted by treatment. 
Natural log transformed AUCWeek 2, AUC∞(if data permit), AUClast and Cmax will be analyzed 
using an analysis of covariance model with treatment as a fixed effect and weight as a continuous 
covariate. Estimates of the adjusted mean differences (Test-Reference) and corresponding 90% 
CIs will be obtained from the model. The adjusted mean differences and 90% CIs for the 
differences will be exponentiated to provide estimates of the ratio of adjusted geometric means

(Test/Reference) and 90% CIs for the ratios. Single doses of 108 mg of vedolizumab administered 
as PFS (reference treatment) will be compared vs PFS+AI (test treatment). 
Additional statistical analyses may be performed if deemed appropriate.
A more detailed description of the planned analyses will be presented in the SAP.
13.1.4
Safety Analysis
For all safety summary tables stated under this section, the tables will be summarized by treatment, 
for all subjects. AEs will be summarized using the safety analysis set. 
All AEs will be coded using MedDRA. Data will be summarized using preferred term and primary 
system organ class.
The number and percentage of subjects with TEAEs, defined as any AEs, regardless of 
relationship to study drug, AESIs for vedolizumab (ie, PML, liver injury, injection site reactions), 
and SAEs, which occur on or after dosing in subjects, will be summarized by MedDRA system 
organ class, and preferred term, by severity, and by relationship to study drug. Separate summaries 
will also be generated for AEs by treatment-related and severity. Data listings will be provided for 
all AEs (including PTEs for enrolled subjects), AEs leading to study drug discontinuation, AEs 
leading to study visit discontinuation, SAEs, and AEs resulting in death.
Baseline, postbaseline, and change from Baseline in clinical laboratory tests, vital signs, and ECG 
results will be summarized. Subjects with markedly abnormal values for laboratory tests, vital 
signs and ECG results will be tabulated. The mapping of the subjects who meet the markedly 
abnormal value criteria will be listed as a table. Individual results for clinical laboratory tests, vital 
signs and ECG measures will be listed.
Data from the LTFU survey will be summarized descriptively.
VNS pain scale assessment data will be summarized.
The proportion of subjects with positive AVA and proportion of subjects with positive neutralizing 
AVA during the study will be summarized at each visit. 
13.2
Interim Analysis and Criteria for Early Termination
No interim analysis is planned.
13.3
Determination of Sample Size
The sample size of 12 subjects per group is considered to be sufficient for exploratory purposes. 
The study is not powered for statistical hypothesis testing.

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 CRFs. Source documents are defined as original documents, data, and records. 
The investigator and study site 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 the 
sponsor’s designee (as long as blinding is not jeopardized), including but not limited to the 
Investigator’s Binder, study drug, 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 CRFs 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. A Protocol Deviation Form should be completed by the site and signed by the sponsor 
or designee for any significant deviation from the protocol. 
However, blood samples not collected within the interval specified for the scheduled sample time 
should be reported to Takeda using the Protocol Deviation Form.
Protocol Deviation Forms are to be completed for PK samples collected outside 10% of nominal 
time without date and time of sampling collection.
14.3
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 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 study site 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 because of 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 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 study. Until the site receives notification no 
protocol activities, including screening may occur. 
Study 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.

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 before 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 before 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 before 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 
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.

Vedolizumab SC
Study No. VedolizumabSC-1021
Page 63 of 74
Protocol 
11 December 2017
CONFIDENTIAL
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 trial database or documentation via a subject 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 the monitor or the sponsor’s designee, 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 CRF).
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 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 study site agreement. In the event of any discrepancy between the protocol and 
the study site agreement, the study site agreement will prevail.

Protocol 
11 December 2017
CONFIDENTIAL
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 all 
interventional clinical trials it sponsors anywhere in the world on ClinicalTrials.gov and/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 study 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 the sponsor providing this information to callers must provide the 
sponsor 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 study subjects. Refer to 
the 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.

(a) Days 10 and 15 have a ±1-day window. Days 29 and 43 have a ±2-day window. Days 64, 85, 106, 127/ET, and 168 have a ±3 day window.
(b) Informed consent must be signed before any study-specific procedures are performed.
(c) All subjects must have a negative QuantiFERON test at Screening. Initial indeterminate results will be repeated; a subject with 2 indeterminate results will be excluded. 
(d) The PML checklist is administered at Screening, on Day 1 before the administration of study drug, and 127±3/ET, and at any unscheduled visits. A wallet card that denotes key 
study information, including signs and symptoms of PML, will be distributed to all subjects at Screening.
(e) A physical examination will be performed at Screening, on Days -1, 1, 8, 29, and at the Final Visit Day 127/ET. All physical examinations will be performed by the investigator or 
subinvestigator. Clinically significant findings on the physical examination that occur after dosing with study drug will be recorded as AEs.
(f) Vital signs (oral temperature, respiration, pulse, and blood pressure) will be obtained at Screening, Check-in (Day -1), Day 1 (predose, postdose), and Final Visit Day 127±3/ET. 
For Day 1, heart rate and blood pressure will be measured after 5 minutes in the supine position and at 1 and 3 minutes after standing. For Day 127±3/ET, heart rate and blood pressure 
will be measured after 5 minutes supine only. 
(g) Height and weight will be measured and BMI will be calculated at Screening. Weight will also be measured at Check-in Day -1 and Day 106±3.
(h) All ongoing medications from Screening through Final Visit Day 127/ET will be recorded.
(i) Standard 12-lead ECGs will be recorded at Screening, Check-in (Day -1), Day 1 (predose [within 0.5 hours before dosing the SC injection]), Day 8, and Final Visit Day 127/ET. 
When an ECG recording is scheduled for the same day as blood draws (eg, PK or AVA sampling), the ECG recording will be collected 5 minutes before the nominal time of the blood 
sample. 
(j) With the exception of the Screening Visit, clinical laboratory tests (hematology, serum chemistry, and urinalysis) require a minimum 10-hour overnight fast. 
(k) A serum pregnancy test is required for women of childbearing potential only. Pregnancy avoidance counseling will also be performed. 
(l) An FSH level will be obtained on women who are postmenopausal (ie, 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).
(m) Subjects will be confined to the clinic for 2 nights (Day -1 to Day 2, inclusive). 
(n) The pain scale will be administered immediately following the SC injection, and a second assessment will be performed between 15 and 30 minutes following the injection.
(o) Blood samples for determination of AVA will be collected at predose on Day 1 (within 0.5 hours before dosing), Days 29, 64, 85, 106, and 127/ET postdose. AVA positive 
samples will be further analyzed for neutralizing AVA. If a subject experiences an SAE, a blood sample for AVA assessment should be obtained at the unscheduled visit.
(p) Blood samples for PK analyses of vedolizumab will be collected beginning predose on Day 1 (within 0.5 hours before the SC injection) and then at 2, 8, 24, 72, 120, and 168 hours 
after Day 1 dosing, and on Days 10, 15, 29, 43, 64, 85, 106, and Final Visit Day 127/ET. If a subject experiences an SAE, a blood sample for PK analysis should also be obtained at 
the unscheduled visit. PK samples will be collected at ET at the discretion of the investigator.
(q) PTEs will be captured following the signing of the informed consent at Screening. Routine collection of AEs will occur from the administration of study drug until Final Visit Day 
127/ET and the unscheduled visit. Any new AEs will be recorded in the CRFs and site source document. If any SAE is reported spontaneously to the investigator following the AE 
collection period, the event will be reported to the sponsor if it is considered to be related to study participation.

Appendix B
Responsibilities of the Investigator
Clinical research studies sponsored by the sponsor are subject to ICH GCP and all the applicable 
local laws and regulations. The responsibilities imposed on investigators by the FDA are 
summarized in the “Statement of Investigator” (Form FDA 1572), which must be completed and 
signed before the investigator may participate in this study.
The investigator agrees to assume the following responsibilities by signing a Form FDA 1572:
1. Conduct the study in accordance with the protocol.
2. Personally conduct or supervise the staff who will assist in the protocol.
3. If the investigator/institution retains the services of any individual or party to perform study 
related duties and functions, the investigator/institution should ensure that this individual or 
party is qualified to perform those study related duties and functions, and should implement 
procedures to ensure the integrity of the study related duties and functions performed and any 
data generated.
4. Ensure that study related procedures; including study specific (nonroutine/nonstandard panel) 
screening assessments are NOT performed on potential subjects, before the receipt of written 
approval from relevant governing bodies/authorities.
5. Ensure that all colleagues and employees assisting in the conduct of the study are informed of 
these obligations.
6. Secure prior approval of the study and any changes by an appropriate IRB/IEC that conform to 
21 Code of Federal Regulations (CFR) Part 56, ICH, and local regulatory requirements.
7. Ensure that the IRB/IEC will be responsible for initial review, continuing review, and approval 
of the protocol. Promptly report to the IRB/IEC all changes in research activity and all 
anticipated risks to subjects. Make at least yearly reports on the progress of the study to the 
IRB/IEC, and issue a final report within 3 months of study completion.

Collection, Storage, and Shipment of Bioanalytical Samples 
Instructions for Processing of Serum Samples for PK Analysis of Vedolizumab
1. Collect 5 mL of venous blood into a Becton-Dickinson Vacutainer. For all vedolizumab 
samples, blood samples should be collected into red stopper vacutainers. Direct venipuncture 
is the only method of blood collection.
2. Allow the red top Vacutainer to sit at room temperature for approximately 30 to 60 minutes 
(refer to product information for correct time) to ensure proper clot formation.
3. To separate the serum samples, centrifuge the Vacutainers for 10 minutes at approximately 
1100 to 1300 relative centrifugal force at room temperature in a centrifuge. Note: if using a 
collection device other than Becton-Dickinson, refer to manufacturer’s instruction for proper 
centrifugation force and time.
4. To ensure a more homogeneous sample, all serum should first be transferred into 1 aliquot. 
From there, split the serum evenly between the 2 aliquots into polypropylene tubes. A 
minimum of 1.0 mL needs to be obtained for each sample. Labeling may include protocol 
number (VedolizumabSC-1021), matrix (ie, serum), analyte (vedolizumab), randomization 
sequence number, nominal day and time, and either “SET 1” (for original sample) or “SET 2” 
(for duplicate sample).
5. Cap the labeled storage tubes and freeze the serum samples immediately at approximately 
-70°C. No more than 1 hour and 45 minutes must be allowed to elapse between collecting 
blood and freezing the serum sample.
6. Keep samples frozen at approximately -70°C or lower until shipment to Quest Pharmaceutical 
Services (QPS), Newark, DE before shipment to QPS. “SET 1” samples will be shipped first 
on dry ice, followed by shipment of duplicate “SET 2” samples after “SET 1” samples have 
been received.
