IND No.: 
Not Applicable
EudraCT No.:
Not Applicable
Study Number: Vedolizumab-1014
Phase: 1
Study Design:
This is an open-label, single-center, phase 1 study to determine the pharmacokinetics (PK) of single intravenous dose 
of vedolizumab 300 mg in healthy adult Chinese subjects. 
Subjects will be kept in the study unit for at least 3 days after the start of infusion on Day 1 for safety and PK 
assessments before discharge. The confinement period will be a minimum of 3 days to a maximum of 7 days.
Subjects will return to the study unit periodically according to the predetermined PK sampling scheduled until 
Day 127 or Early Termination (ET). Additionally, subjects will be required to participate in a long-term follow-up 
(LTFU) safety survey by telephone, 6 months after the dose of study drug. 
The total duration on study for each subject will be approximately 7.0 months, including Screening.

Main Criteria for Inclusion:
Healthy male or non-pregnant, non-lactating female Chinese subjects aged 18-45 years inclusive, who are willing and 
able to comply with the study schedule and assessments. The subject weighs at least 50 kg and has a body mass index 
(BMI) of between 19.0 and 26.0 kg/m2, inclusive at Screening.
Main Criteria for Exclusion:
The subject has received any investigational compound within 30 days prior to dosing of study medication or history 
of treatment with another monoclonal antibody within 6 months to dosing of study medication.
The subject has received vedolizumab in a previous clinical study or as a therapeutic agent.
The subject has uncontrolled, clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, 
gastrointestinal, urologic, immunologic, endocrine disease, or psychiatric disease, or other abnormality, which may 
impact the ability of the subject to participate or potentially confound the study results. 
The subject has a known hypersensitivity to any component of the formulation of vedolizumab IV.
The subject is unable to attend all study days or comply with protocol requirements.
In addition, subject may not use any excluded medication or supplement to be outlined in the protocol.
Main Criteria for Evaluation and Analyses:
The primary endpoints for this study are:

Maximum observed serum concentration (Cmax).

Area under the serum concentration-time curve from time 0 to time of the last measureable concentration 
(AUClast).

Area under the serum concentration-time curve from time 0 to infinity (AUC∞).
The secondary endpoints for this study are:

Proportion of subjects with positive anti-vedolizumab antibody (AVA) during the study.

Proportion of subjects with positive neutralizing AVA during the study.

Safety assessment: Percentage of subjects with adverse events (AEs), percentage of subjects with adverse events 
of special interest (AESIs, including serious infections, including opportunistic infection such as progressive 
multifocal leukoencephalopathy (PML), liver injury, malignancies and infusion related reactions and 
hypersensitivity), percentage of subjects with serious adverse events (SAEs), number of subjects with markedly 
abnormal vital signs, number of subjects with markedly abnormal laboratory tests (clinical chemistry, 
hematology, coagulation, urinalysis), and number of subjects with markedly abnormal 12-lead 
electrocardiograms (ECGs).
Statistical Considerations:
Descriptive statistics will be used to summarize serum concentrations of vedolizumab over each scheduled sampling 
time. Individual serum concentration-time data will be presented as listings. 
Descriptive statistics will be used to summarize serum PK parameters of vedolizumab. Individual serum PK 
parameters will be presented in a data listing.
All AEs will be presented in listings: AEs and AESIs will be summarized. Individual results of laboratory tests 
(hematology, chemistry, and urinalysis), vital signs, and ECGs will be listed, and observed values will be summarized 
for every collection time point. Physical examination findings will be presented in the data listings.
The proportion of subjects with positive AVA will be summarized by the scheduled sampling time. The proportion of 
subjects with neutralizing AVA by the end of the study will be summarized. Titers of AVA and neutralizing AVA will 
be listed.
Additional analyses may be performed as needed.

monoclonal antibody directed against the human lymphocyte integrin α4β7. The α4β7integrin 
mediates lymphocyte trafficking to the gastrointestinal (GI) mucosa and gut-associated lymphoid 
tissue through adhesive interaction with mucosal addressin cell adhesion molecule-1 
(MAdCAM-1), which is expressed on the endothelium of mesenteric lymph nodes and GI mucosa
[1-4]. Vedolizumab binds the α4β7 integrin, antagonizing its adherence to MAdCAM-1 and as 
such, impairs the migration of gut homing leukocytes into GI mucosa. Due to its gut selective 
immunomodulatory properties [5], vedolizumab has been developed as a treatment for ulcerative 
colitis (UC) and Crohn’s disease (CD).
The effectiveness and safety of vedolizumab intended for intravenous (IV) use (vedolizumab IV, 
vedolizumab for injection, for intravenous use) for UC and CD have been established in pivotal 
clinical trials in subjects who had not responded adequately to corticosteroids, 
immunomodulators, or tumor necrosis factor-alpha (TNF-α) antagonists [6-8]. 
As of 19 November 2016 (the cut-off date of the most recent Periodic Benefit-Risk Evaluation 
Report), more than 4200 subjects have received at least 1 dose of vedolizumab across all studies in 
the clinical development program. 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.
Single- and multiple-dose pharmacokinetics (PK) of vedolizumab have been studied in healthy 
subjects and in patients with moderately to severely active UC or CD. Similar PK was observed in 
healthy subjects, UC patients, and CD patients. Vedolizumab exhibits target-mediated drug 
disposition; hence, its elimination is characterized by linear and nonlinear processes. Following IV 
infusion, the serum concentrations of vedolizumab generally fell in a biexponential fashion until 
approximately 1 to 10 µg/mL, with a linear total body clearance of approximately 0.157 L/day and 
a serum half-life of around 25 days. Thereafter, the serum concentrations fell in a nonlinear 
fashion. The volume of distribution for vedolizumab is approximately 5 L. Vedolizumab was not 
detected in the cerebrospinal fluid at 5 weeks after a single IV administration in healthy subjects. 
Different intrinsic and extrinsic factors, including age, body weight, serum albumin, severity of 
disease state, prior treatment with TNF-α antagonist, coadministration with immunomodulators 
(including azathioprine, 6-mercaptopurine, methotrexate) or aminosalicylates, did not impact the 
PK of vedolizumab in subjects with UC or CD based on population PK analysis, as such, no dose 
adjustment is recommended for any of the above-mentioned covariates. PK of vedolizumab was 
similar between Japanese and Western subjects.
As of July 2014, vedolizumab IV has been granted marketing approval in the United States and 
additional countries for the treatment of adult patients with moderately to severely active UC or

CD, who have failed conventional treatment, including immunomodulators, corticosteroids, or 
TNF-α antagonists. The recommended dosage for UC and CD is 300 mg vedolizumab IV infused 
over approximately 30 minutes at Weeks 0, 2, and 6, then once every 8 weeks (Q8W) thereafter. 
4.2
Rationale for the Proposed Study
This phase 1 study is designed to meet the requirements of the China Food and Drug 
Administration (CFDA) for registration of vedolizumab IV in China. The effectiveness and safety 
of vedolizumab for UC and CD have been established in global clinical trials in support of 
marketing approval in the United States and additional countries. The main objective of this 
open-label, single-dose study is to assess the PK of vedolizumab in Chinese subjects and to allow 
comparison with the clinical data previously acquired in other regions, including North America, 
Europe, and Japan, etc. The results from this phase 1 study and the proposed phase 3 efficacy and 
safety studies in Chinese subjects with moderately to severely active UC or CD, along with 
available clinical data in other regions, will be used to support the registration of vedolizumab IV 
in China.

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is an open-label, single-center, phase 1 study to determine the PK of single dose of 
vedolizumab IV 300 mg in healthy adult Chinese subjects. The number of subjects to be dosed in 
the study is 16. Since vedolizumab is intended to be used by both male and female subjects with 
UC or CD, effort will be made to enroll an equal number of male and female subjects in this study. 
Subjects will be kept in the study unit for at least 3 days after the start of infusion on Day 1 for 
safety and PK assessments before discharge. The confinement period will be a minimum of 3 days 
and a maximum of 7 days.
Subjects will return to the study units periodically according to the predetermined PK sampling 
scheduled until Day 127 or Early Termination (ET). Additionally, subjects will be required to 
participate in a long-term follow-up (LTFU) safety survey by telephone, 6 months after the dose of 
study drug. The total duration on study for each subject will be approximately 7.0 months, 
including screening. 
A schematic of the study design is included as Figure 6.a. A schedule of assessments is listed in

6.2
Justification for Study Design, Dose, and Endpoints
This is a single-center, open-label, single-dose study using vedolizumab IV 300 mg infused IV 
over 30 minutes. The objective of the study is to evaluate the PK of vedolizumab following a 
single IV infusion of 300 mg vedolizumab IV in healthy adult Chinese subjects. Vedolizumab IV 
300 mg dosing at Weeks 0, 2, and 6, and Q8W thereafter is the recommended regimen for subjects 
with moderately to severely active UC or CD in the United States, European Union, and Australia, 
as well as the dose regimen being used in the ongoing phase 3 studies in UC and CD subjects in 
Japan and the planned dose regimen in the phase 3 studies in China.

Given the long half-life of vedolizumab (approximately 25 days), blood samples will be collected 
up to 18 weeks (>5 half-lives) to sufficiently assess vedolizumab PK after IV infusion. Since 
vedolizumab is intended to be administered Q8W during the maintenance phase in the phase 3 
studies in China, the accumulation after repeated dosing is expected to be minimal. This is 
supported by the fact that the trough serum concentration of vedolizumab was maintained at 
similar levels after reaching steady state in the completed phase 3 studies. Based on the population 
PK analyses conducted for the completed clinical studies, vedolizumab PK is similar in healthy 
subjects, as well as in subjects with UC or CD. Therefore, a single-dose PK study in healthy 
subjects is considered sufficient to provide the estimates of the steady-state exposure of 
vedolizumab following multiple Q8W maintenance doses in UC or CD patients, and a 
multiple-dose design is not necessary.
The impact of race (Westerns vs Japanese) was assessed through cross-study comparison using 
noncompartmental PK parameters. The dose- and weight-normalized PK parameters observed in 
Japanese subjects with UC (Study CPH-001) were similar to those observed in Western subjects 
with UC (Study C13002), suggesting that there is no effect of race on the PK of vedolizumab. The 
preliminary results from a recently completed single dose bioavailability study in healthy Japanese 
and non-Japanese subjects (MLN0002SC-101) further confirmed the lack of race effect on 
vedolizumab PK. 
The sample size of 16 subjects is considered sufficient to evaluate the PK profiles after single dose 
of vedolizumab IV in adult healthy Chinese subjects. This sample size is not based on statistical 
considerations.

followed by the study procedure and then the meal.
Subjects will be advised to refrain from strenuous exercise from 72 hours before Check-in and 
throughout the confinement period of the study.
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 
medication should be recorded in the electronic case report form (eCRF) using the following 
categories. For screen failure subjects, refer to Section 9.1.17.
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 medication should be discontinued immediately with appropriate clinical follow-up 
(including repeat laboratory tests, until a subject’s laboratory profile has returned to 
normal/baseline status, see Section 9.1.8), if the following circumstances occur at any time 
during study medication treatment:
–
ALT or AST >8 × ULN, or
–
ALT or AST >5 × ULN and persists for more than 2 weeks, or

Vedolizumab IV

–
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 dosing of study medication that the 
subject failed to meet protocol entry criteria or did not adhere to protocol requirements, and 
continued participation poses an unacceptable risk to the subject’s health.
3. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. Attempts to contact the subject must be documented.
4. Voluntary withdrawal. The subject (or subject’s legally acceptable representative) wishes to 
withdraw from the study. The reason for withdrawal, if provided, should be recorded in the 
eCRF.
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (ie, withdrawal due to an 
AE).
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 eCRF.
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 ET 
Visit. Discontinued or withdrawn subjects will not be replaced but additional subjects may be 
enrolled as needed.

assigned by clinic site personnel in sequential order and which is used for all other procedures to 
identify the subjects throughout the study, as well as to facilitate the prelabeling of PK samples, 
contained on the PK transport vials shipped to the bioanalytical laboratory, and will be used by the 
laboratory to report the subject data results.
8.3
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 (vedolizumab IV 300 mg), 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. 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:

Frequently verifying that actual inventory matches documented inventory.


The investigator or designee must record the current inventory of all sponsor-supplied drugs
(vedolizumab IV 300 mg) on a sponsor-approved drug accountability log. The following 
information will be recorded at a minimum: protocol number and title, name of investigator, site 
identifier and number, description of sponsor-supplied drugs, expiry and/or retest date, date and 
amount dispensed, including initials, seal, or signature of the person dispensing the drug. The log 
should include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.
Prior to 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/or 
destruction, 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.

STUDY PLAN
9.1
Study Procedures
The following sections describe the study procedures and data to be collected. For each procedure, 
subjects are to be assessed by the same investigator or site personnel whenever possible. The 
Schedule of Study Procedures is located in Appendix A.
9.1.1
Informed Consent Procedure
The requirements of the informed consent are described in Section 15.2.
Informed consent must be obtained prior to the subject entering into the study, and before any 
protocol-directed procedures are performed, including requesting that a subject fast for laboratory 
evaluations.
A unique subject identification (ID) number (Subject ID = Site number + 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, 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 stopped at or prior to 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 28 days prior to signing of informed consent.
9.1.3
Physical Examination Procedure
A physical examination will consist of the following body systems: (1) eyes; (2) ears, nose, throat; 
(3) cardiovascular system; (4) respiratory system; (5) GI system; (6) dermatologic system; 
(7) extremities; (8) musculoskeletal system; (9) nervous system; (10) lymph nodes; (11) other.
Any abnormal finding on a pretreatment physical examination assessment must be assessed as Not 
Clinically Significant (NCS) or Clinically Significant (CS) by the investigator and recorded in the 
source document and eCRF. All CS findings/changes will be recorded as a PTE or concurrent 
medical condition in the source document and on the appropriate eCRF described in Section 10.0
or Section 9.1.7. 
On subsequent examinations, any abnormal change from the pretreatment physical examination 
assessment occurring immediately prior to the start of the investigational drug (Day 1) must be 
assessed as NCS or CS by the investigator and recorded in the source document and eCRF. Any 

Vedolizumab IV

CONFIDENTIAL
CS change or new diagnosis as a result of a CS change, as determined by the investigator, will be 
recorded as an AE in source documentation and on the PTE/AE eCRF described in Section 10.0.
9.1.4
Weight, Height and BMI
A subject should have weight and height measured while wearing indoor clothing and with shoes 
off. The BMI is calculated using metric units with the formula provided below. The Takeda 
standard for collecting height is centimeters without decimal places and for weight it is kg with 
1 decimal place. BMI should be derived as:
Metric:
BMI = weight (kg)/[height (m)]2
Note that although height is reported in centimeters, the formula uses meters for height; meters can 
be determined from centimeters by dividing by 100. Thus, for example, if height=176 cm 
(1.76 meters) and weight=79.2 kg, then BMI=79.2/1.762=25.5 kg/m2 
9.1.5
Vital Sign Procedure
Vital signs (temperature, respiration, pulse, and blood pressure) will be obtained at Screening, 
Check-in (Day -1), Day 1 (predose, and within ±5 minutes of 1 hour postdose and within 
±30 minutes of 8 hours postdose), Days 2, 8, 10(±1), 15 (±1), 29 (±2), 43(±2), 64 (±3), 85 (±3), 
106 (±3), and Final Visit Day 127(±3)/ET. For Days 1 and 2, heart rate and blood pressure will be 
measured after 5 minutes supine and again at 1 and 3 minutes after standing. For Days 8, 10(±1), 
15 (±1), 29 (±2), 43(±2), 64 (±3), 85 (±3), 106 (±3) and Final Visit Day 127(±3)/ET, heart rate and 
blood pressure will be measured after 5 minutes supine only. 
9.1.6
Documentation of Concomitant Medications
Concomitant medication is any drug given in addition to the study medication. These may be 
prescribed by a physician or obtained by the subject over the counter. Concomitant medication is 
not provided by Takeda. At each study visit, subjects will be asked whether they have taken any 
medication other than the study medication (used from signing of informed consent through the 
end of the study), and all medication including vitamin supplements, over-the-counter 
medications, and oral herbal preparations, must be recorded in the eCRF. 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. 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 48-72 hours after the abnormality was noted.
(Please refer to Section 7.5 for discontinuation criteria, and Section 10.2.3 for the appropriate 
guidance on Reporting of Abnormal Liver Function Tests in relation to ALT or AST >3 ×ULN in 
conjunction with total bilirubin >2 ×ULN.)
If the ALT or AST remains elevated >3 ×ULN on these 2 consecutive occasions, the investigator 
must contact the Medical Monitor for consideration of additional testing, close monitoring, 
possible discontinuation of study medication, discussion of the relevant subject details and 
possible alternative etiologies. The abnormality should be recorded as an AE (please refer to 
Section 10.2.3 Reporting of Abnormal Liver Function Tests for reporting requirements).
9.1.9
Contraception and Pregnancy Avoidance Procedure
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study medication, nonsterilized** male subjects who are sexually active with a female 
partner of childbearing potential* must use barrier contraception (eg, condom with spermicidal 
cream or jelly). In addition, they must be advised not to donate sperm during this period.
From signing of informed consent, throughout the duration of the study, and for 18 weeks after last 
dose of study medication, female subjects of childbearing potential* who are sexually active with a 
nonsterilized male partner** must use adequate contraception. In addition they must be advised 
not to donate ova during this period.
*Females NOT of childbearing potential are defined as those who have been surgically sterilized 
(hysterectomy, bilateral oophorectomy or tubal ligation) or who are postmenopausal (defined as at 
least 1 year since last regular menses with an FSH >40 IU/L or at least 5 years since last regular 
menses, confirmed before any study medication is implemented).
**Sterilized males should be at least 1 year postvasectomy and have confirmed that they have 
obtained documentation of the absence of sperm in the ejaculate.
An acceptable method of contraception is defined as one that has no higher than a 1% failure rate. 
In this study, where medications and devices containing hormones are included, the only 
acceptable methods of contraception are:

CONFIDENTIAL
Barrier methods (each time the 
subject has intercourse):
Intrauterine devices 
(IUDs):
#Hormonal contraceptives:
Male condom PLUS spermicide.
Cap (plus spermicidal cream or 
jelly) PLUS male condom and 
spermicide.
Diaphragm (plus spermicidal 
cream or jelly) PLUS male 
condom and spermicide.
Copper T PLUS condom 
or spermicide.
#Progesterone T PLUS 
condom or spermicide.
Implants.
Hormone shot/injection.
Combined pill.
Minipill.
Patch.
Vaginal ring PLUS male 
condom and spermicide.
Subjects will be provided with information on acceptable methods of contraception as part of the 
subject informed consent process and will be asked to sign a consent form stating that they 
understand the requirements for avoidance of pregnancy, donation of ova and sperm donation 
during the course of the study. During the course of the study, regular serum hCG pregnancy tests 
will be performed only for women of childbearing potential and subjects will receive continued 
guidance with respect to the avoidance of pregnancy and sperm/ova donation as part of the study 
procedure (Appendix A). In addition to a negative serum hCG pregnancy test at Screening, 
subjects also must have a negative serum hCG pregnancy test at Check-in (Day -1).
In addition, male subjects must be advised not to donate sperm from signing of informed consent 
to 18 weeks after the last dose of study medication.
9.1.10 Pregnancy
If any subject is found to be pregnant during the study she should be withdrawn and any 
sponsor-supplied drug (vedolizumab IV) 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 medication, eg, after Day 1or within 
18 weeks of the last dose of active study medication, the pregnancy should be reported 
immediately, using a pregnancy notification form, to the contact listed in Section 1.0.
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 subject/female 
partner of the subject was participating in a clinical study at the time she became pregnant and 
provide details of treatment the subject received (blinded or unblinded, as applicable).
All reported pregnancies 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
A standard 12-lead ECG will be recorded at Screening Visit, Check-in (Day -1), Day 1 (predose 
[within 0.5 hours prior to dosing] and at 8 hours after the start of infusion, Day 8 and Final Visit 
Day 127 (±3)/ET. When ECG recording is scheduled for the same visit day as blood draws (eg, PK 
or AVA sampling), the ECG recording should be collected before the blood sample. Single ECGs 
will be taken for all applicable visits. Additional unscheduled ECGs may be recorded where 
clinically necessary for subject safety.
ECGs will be read automatically and also, the investigator or sub-investigator 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, QTcF and QT interval with Bazett correction method (QTcB) 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 eCRF. 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 determination of AVA will be collected at day 1 predose (within 0.5 hours 
prior to dosing), Days 10 (±1), 29 (±2), 43 (±2), 64 (±3), 85 (±3), 106 (±3) and 127(±3)/ET 
postdose. A sample will be assessed for neutralizing AVA if AVA is detected.
Serum titers of AVA will be determined using a validated assay. Neutralizing AVA will be 
determined using a validated assay.
Please refer to the Study Manual for information on sample collection and preparation.
A blood sample for AVA assessment will also be obtained at the unscheduled visit for subjects 
experience an SAE.
9.1.13 Pharmacokinetic Sample Collection
9.1.13.1 Collection of Serum for Pharmacokinetic Sampling
Blood samples (one 5-mL sample per scheduled time) for PK analysis of vedolizumab will be 
collected into red-top Vacutainers for serum according to the schedule in Appendix A. Instructions 
for sample processing and shipment are provided in Appendix E.
Note: On Day 1, PK samples should not be collected from the arm where the vedolizumab IV 
infusion is performed. All PK samples should be collected as specified in Table 9.b even if the 
vedolizumab IV infusion is discontinued before the complete dose is administered to the subject.

9.1.13.2 Bioanalytical Methods
Serum concentrations of vedolizumab will be measured using a validated assay.
9.1.14 Pharmacokinetic Parameters
The PK parameters of vedolizumab will be determined from the concentration-time profiles for all 
evaluable subjects using a non-compartmental analysis method. The PK parameters, including 
tmax, Cmax, AUClast, AUC, and t1/2z, will be determined from serum concentration-time data for all 
evaluable subjects. Actual sampling times, rather than scheduled sampling times, will be used in 
all computations involving sampling times.

9.1.16 PML Checklist
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 prior to dose, Day 127(±3)/ET Visit, and at any unscheduled visits.
Any subjects reporting signs 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 Program for PML (RAMP). The symptoms from a positive PML checklist will be 
recorded as an AE. Additional information and tools for the RAMP can be found in the Study 
Manual.
9.1.17 Documentation of Screen Failure
Investigators must account for all subjects who sign informed consent. If the subject is found to be 
not eligible at this visit, the investigator should complete the eCRF screen failure form.
The primary reason for screen failure is recorded in the eCRF using the following categories:

PTE/AE.

Did not meet inclusion criteria or did meet exclusion criteria. 

Significant protocol deviation.

Lost to follow-up.

Voluntary withdrawal 

Study termination.

Other 
Subject 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.
9.1.18 Documentation of Study Entrance
Only subjects who meet all of the inclusion criteria and none of the exclusion criteria are eligible 
for entrance into the treatment phase.
If the subject is found to be not eligible for entrance, the investigator should record the primary 
reason for failure on the applicable eCRF.

Monitoring Subject Treatment Compliance
Study medication will be administered 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 eCRFs. 
An inventory of the study medication 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).
9.3.1
Screening 
Subjects will be screened within 28 days prior to the dosing of study medication. Subjects will be 
screened in accordance with predefined inclusion and exclusion criteria as described in 
Section 7.0. See Section 9.1.15 for procedures for documenting screening failures.
9.3.2
Study Entrance
Study entrance into the treatment phase will take place on Day 1.
If the subject has satisfied all of the inclusion criteria and none of the exclusion criteria for study 
entrance, the subject should be assigned to treatment as described in Section 8.2. Subjects will be 
administered a dose of study medication in the unit under the supervision of the investigator or 
designee, as described in Section 8.2. The procedure for documenting Screening failures is 
provided in Section 9.1.15.
9.3.3
Final Visit
The Final Visit will be performed on Day 127 (±3 days). 
For all subjects receiving study medication, the investigator must complete the End of Study eCRF 
page.
9.3.4
Early Termination
The reason for discontinuation must be documented in the source document and eCRF. 
For all subjects receiving study medication, the investigator must complete the End of Study eCRF 
page.
9.3.5
Follow-up
Additionally, upon completion of or early termination from the study, all subjects will participate 
in a LTFU safety questionnaire on Day 168 (±3 days). The questionnaire will be administered by 
telephone at 6 months from the last dose of study drug.

Biological Sample Retention and Destruction
The sponsor has put into place a system to protect the subjects’ personal information to ensure 
optimal confidentiality and defined standard processes for sample and data collection, storage, 
analysis, and destruction.
The samples will be sent to a central laboratory that processes the blood sample and serves as a 
secure storage facility. The sponsor and researchers working with the sponsor will have access to 
the samples collected and any test results. All samples collected during the study will be stored 
securely with limited access and the sponsor will require anyone who works with the samples to 
agree to hold the research information and any results in confidence.
The sample will be labeled with a unique sample identifier similar to labeling in the main study but 
using a code that is different from the code attached to the health information and other clinical test 
results collected in the study. The sample and data are linked to personal health information with 
code numbers. This link means that the subject may be identified but only indirectly. The code 
numbers will be kept secure by or on behalf of the sponsor.

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 prior to administration of any study 
medication; it does not necessarily have to have a causal relationship with study participation.
10.1.2 AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a drug whether or 
not it is considered related to the drug.
10.1.3 Additional Points to Consider for PTEs and AEs
An untoward finding generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition. (Intermittent 
events for pre-existing conditions underlying disease should not be considered PTEs or AEs.)

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study medication or a concomitant medication.

Be considered unfavorable by the investigator for any reason. 

PTEs/AEs caused by a study procedure (eg, a bruise after blood draw) should be recorded as a 
PTE/AE.
Diagnoses vs signs and symptoms:

Each event should be recorded to represent a single diagnosis. Accompanying signs (including 
abnormal laboratory values or ECG findings) or symptoms should NOT be recorded as 
additional AEs. If a diagnosis is unknown, sign(s) or symptom(s) should be recorded 
appropriately as a PTE(s) or as an AE(s).
Laboratory values and ECG findings:

Changes in laboratory values or ECG parameters are only considered to be PTEs or AEs if they 
are judged to be clinically significant (ie, if some action or intervention is required or if the 
investigator judges the change to be beyond the range of normal physiologic fluctuation). A 
laboratory re-test and/or continued monitoring of an abnormal value are not considered an 

Vedolizumab IV

Protocol Incorporating Amendment No. 02
10 May 2018
CONFIDENTIAL
intervention. In addition, repeated or additional noninvasive testing for verification, evaluation 
or monitoring of an abnormality is not considered an intervention.

If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (eg, increased creatinine in renal failure), the diagnosis only should be 
reported appropriately as a PTE or as an AE.
Pre-existing conditions:

Pre-existing conditions (present at the time of signing of informed consent) are considered 
concurrent medical conditions and should NOT be recorded as PTEs or AEs. Baseline 
evaluations (eg, laboratory tests, ECG, X-rays etc.) should NOT be recorded as PTEs unless 
related to study procedures. However, if the subject experiences a worsening or complication 
of such a concurrent condition, the worsening or complication should be recorded 
appropriately as a PTE (worsening or complication occurs before start of study medication) or 
an AE (worsening or complication occurs after start of study medication). Investigators should 
ensure that the event term recorded captures the change in the condition (eg, “worsening 
of…”).

If a subject has a pre-existing episodic condition (eg, asthma, epilepsy) any occurrence of an 
episode should only be captured as a PTE/AE if the episodes become more frequent, serious or 
severe in nature, that is, investigators should ensure that the AE term recorded captures the 
change in the condition from Baseline (eg “worsening of…”).

If a subject has a degenerative concurrent condition (eg, cataracts, rheumatoid arthritis), 
worsening of the condition should only be captured as a PTE/AE if occurring to a greater 
extent to that which would be expected. Again, investigators should ensure that the AE term 
recorded captures the change in the condition (eg, “worsening of…”).
Worsening of PTEs or AEs:

If the subject experiences a worsening or complication of a PTE after starting administration of 
the study medication, the worsening or complication should be recorded appropriately as an 
AE. Investigators should ensure that the AE term recorded captures the change in the condition 
(eg, “worsening of…”).

If the subject experiences a worsening or complication of an AE after any change in study 
medication, the worsening or complication should be recorded as a new AE. Investigators 
should ensure that the AE term recorded captures the change in the condition (eg, “worsening 
of…”).
Changes in severity of AEs /Serious PTEs:

If the subject experiences changes in severity of an AE/serious PTE, the event should be 
captured once with the maximum severity recorded.

Preplanned surgeries or procedures:

Preplanned procedures (surgeries or therapies) that were scheduled prior to signing of 
informed consent are not considered PTEs or AEs. However, if a preplanned procedure is 
performed early (eg, as an emergency) due to a worsening of the pre-existing condition, the 
worsening of the condition should be captured appropriately as a PTE or an AE. Complications 
resulting from any planned surgery should be reported as AEs.
Elective surgeries or procedures:

Elective procedures performed where there is no change in the subject’s medical condition 
should not be recorded as PTEs or AEs, but should be documented in the subject’s source 
documents. Complications resulting from an elective surgery should be reported as AEs.
Overdose:

Cases of overdose with any medication without manifested side effects are NOT considered 
PTEs or AEs, but instead will be documented on an Overdose page of the eCRF. Any 
manifested side effects will be considered PTEs or AEs and will be recorded on the AE page of 
the eCRF.
10.1.4 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
if it were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. 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).

PTEs that fulfill 1 or more of the serious criteria above are also to be considered SAEs and should 
be reported and followed up in the same manner (see Sections 10.2.2 and 10.3).
10.1.5 Special Interest AEs
A Special Interest Adverse Event (serious or non-serious) is one of scientific and medical concern 
specific to the compound or program, for which ongoing monitoring and rapid communication by 
the investigator to Takeda may be appropriate. Such events may require further investigation in 
order to characterize and understand them and would be described in protocols and instructions 
provided for investigators as to how and when they should be reported to Takeda. Refer to 
Section 10.2.1.3 for information for special interest AE reporting.
10.1.6 Severity of PTEs and AEs
The different categories of intensity (severity) are characterized as follows:
Mild:
The event is transient and easily tolerated by the subject.
Moderate:
The event causes the subject discomfort and interrupts the subject’s usual activities.
Severe:
The event causes considerable interference with the subject’s usual activities.

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

10.1.13
Outcome

Recovered/Resolved – Subject returned to first assessment status with respect to the AE/PTE.

Recovering/Resolving – the intensity is lowered by one or more stages: the diagnosis or 
signs/symptoms has almost disappeared; the abnormal laboratory value improved, but has not 
returned to the normal range or to baseline; the subject died from a cause other than the 
particular AE/PTE with the condition remaining “recovering/resolving”.

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/ symptoms or laboratory value on the last day of the observed 
study period has got worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE/PTE state remaining “Not 
recovered/not resolved”.

Resolved with sequelae – the subject recovered from an acute AE/PTE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis.

Fatal – the AEs/PTEs which are considered as the cause of death.

Unknown – the course of the AE/PTE cannot be followed up due to hospital change or 
residence change at the end of the subject’s participation in the study.
10.2
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 medication
(Day 1) or until screen failure. For subjects who discontinue prior to study medication 
administration, PTEs are collected until the subject discontinues study participation.
Collection of AEs will commence from the time that the subject is first administered study 
medication (Day 1). Routine collection of AEs will continue until the Final Visit (Day 127±3).
10.2.1.2 PTE and AE Reporting
At each study visit, the investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. Subjects experiencing a 
serious PTE must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or there is a satisfactory explanation for the change. 
Non-serious PTEs, related or unrelated to the study procedure, need not to be followed-up for the 
purposes of the protocol.

All subjects experiencing AEs, whether considered associated with the use of the study medication 
or not, must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or until there is a satisfactory explanation for the 
changes observed. All PTEs and AEs will be documented in the PTE/AE page of the eCRF, 
whether or not the investigator concludes that the event is related to the drug treatment. The 
following information will be documented for each event:
1. Event term.
2. Start and stop date and time.
3. Frequency.
4. Severity.
5. Investigator’s opinion of the causal relationship between the event and administration of study 
medication(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 medication (not applicable for PTEs).
8. Outcome of event.
9. Seriousness.
10.2.1.3 Special Interest AE Reporting
If this special interest AE, which occurs during the treatment period or the follow-up period, is 
considered to be clinically significant based on the criteria below, it should be recorded in an 
special interest AE eCRF or an SAE Form. The Form should be completed and reported to the 
SAE reporting contact in Section 1.0 within 24 hours.
Hypersensitivity Reactions (Including Infusion-Related Reactions). 
Currently, there is no evidence to support the routine prophylactic administration of premedication 
(eg, antihistamines, corticosteroids) to subjects receiving vedolizumab; hence such 
premedications are unlikely to be necessary or beneficial. At the discretion of the investigator, 
however, subjects may be administered premedication prior to any study drug administration. 
Corticosteroids, if given as a premedication, should be limited to the day of administration. 
Vedolizumab IV should be administered by a health care professional prepared to manage 
hypersensitivity reactions including anaphylaxis, if they occur. Appropriate monitoring and 
medical support measure should be available for immediate use.
Subjects should be observed for 2 hours following the infusion at a minimum.
If signs or symptoms of an infusion-related reaction are observed during the administration of 
study medication, it should be immediately discontinued and the subject treated as medically 
appropriate. In the case of a mild reaction, study drug administration may be reinitiated (with 
appropriate premedication) at the discretion of the investigator. Subjects with a severe or serious 

Vedolizumab IV

CONFIDENTIAL
administration-related reaction (eg, shortness of breath, wheezing, stridor, angioedema, life 
change in vital signs) must be withdrawn from the study (see Study Manual).
In all cases of infusion-related reaction, the medical monitor must be informed as soon as practical. 
The disposition of subjects with less severe infusion-related reactions should be discussed with the 
medical monitor.
Serious Infection 
Subjects will be monitored for signs and symptoms of infection and for lymphopenia during the 
study. Subjects with signs and symptoms suggestive of infections, including GI infections, will be 
treated as clinically indicated. Interventions may include antibiotic treatment, if appropriate and/or 
discontinuation of concomitant immunomodulators. Blood, sputum, urine, and/or stool cultures 
should be obtained as appropriate for the detection and diagnosis of infection. Withholding or 
terminating study drug administration may be considered as described in Section 7.5.
Malignancy
All cases of malignancies that are detected during the study will be reported as AEs. Local medical 
practices for the management of malignances will apply. Subjects with history of malignancy 
(except for specific cancers) or at high risk for malignancy will be excluded from the study per the 
exclusion criteria. 
Other 
Other special interest AEs include liver injury and PML, which are discussed in Sections 10.2.3
and 11.1.1, respectively.
The special interest AEs have to be recorded as AEs in the eCRF. 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, 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 ID number.

Investigator’s name.

Name of the study medication(s)

Causality assessment.
The SAE form should be transmitted within 24 hours to the attention of the contact listed in 
Section 1.0.

CONFIDENTIAL
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 Liver Function Tests 
If a subject is noted to have ALT or AST elevated >3 ×ULN on 2 consecutive occasions, the 
abnormality should be recorded as an AE. In addition, an <LFT Increases eCRF> must be 
completed providing additional information on relevant recent history, risk factors, clinical signs 
and symptoms and results of any additional diagnostic tests performed.
If a subject is noted to have ALT or AST >3 ×ULN and total bilirubin >2 ×ULN for which an 
alternative etiology has not been identified, the event should be recorded as an SAE and reported 
as per Section 10.2.2. The investigator must contact the Medical Monitor for discussion of the 
relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or B or 
other acute liver disease or medical history/concurrent medical conditions. Follow-up laboratory 
tests as described in Section 9.1.8 must also be performed. In addition, an <LFT Increases eCRF> 
must be completed and transmitted with the Takeda SAE form (as per Section 10.2.2).
10.3
Follow-up of SAEs
If information 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 an 
investigational medicinal product or that would be sufficient to consider changes in the 
investigational medicinal products administration or in the overall conduct of the trial. The 
investigational site also will forward a copy of all expedited reports to his or her IRB or IEC in 
accordance with national regulations.

STUDY-SPECIFIC COMMITTEES
No steering committee, data safety monitoring committee, or clinical endpoint committee will be 
used in this study. 
11.1
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 Minimization Action Program for PML (RAMP Program)
Natalizumab (TYSABRI), another integrin receptor antagonist, has been associated with PML, a 
rare and often fatal opportunistic infection of the central nervous system. PML is caused by the 
John Cunningham virus (JCV) and typically only occurs in patients who are immunocompromised 
[9,10]. Natalizumab is a pan-α4 integrin antagonist that binds to both the α4β1 and α4β7 integrins 
and inhibits cellular adhesion to vascular cell adhesion molecule-1 (VCAM-1) and MAdCAM-1 
[11,12]. In contrast, vedolizumab binds to the α4β7 integrin only [5] and inhibits adhesion to 
MAdCAM-1, but not VCAM-1. Although no cases of PML have been reported in clinical trials 
with vedolizumab to date, a risk of PML cannot be ruled out.
To address the theoretical risk of the development of PML in subjects treated with vedolizumab, 
the sponsor, with input from renowned PML experts, has developed a Risk Minimization Action 
Program for PML, the RAMP. The complete description of the RAMP program, including 
materials and instructions for its implementation and monitoring, is included in the Study Manual. 
The RAMP is focused on early clinical detection and management of that specific safety risk, 
including the discontinuation of study drug, if applicable. Subjects are assessed for signs and 
symptoms of PML prior to 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). The next dose of study drug will be held until the evaluation is 
complete and results are available. Subsequent doses of study will be administered only if the 
possibility of PML is definitively excluded, as described in the RAMP algorithm. An IAC has 
been stabled as part of the RAMP program to review new neurological signs and symptoms 
potentially consistent with PML, and will provide input regarding subject evaluation and 
management as defined in the IAC charter. 
To ensure 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 subjects about PML and the RAMP 
procedures will be distributed to all sites and are included in the Study Manual. Formal teaching 
and training will be performed for site personnel prior to the start of the study. Subjects will 
receive training and educational materials prior to receiving treatment. The informed consent form 
will contain specific information on the hypothetical risk of PML. Any documented case of PML 
will be reported as an SAE, regardless of whether hospitalization occurs.

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

Vedolizumab IV

approval of a marketing application for a specified drug indication being investigated or, if an 
application is not approved, until at least 2 years after the investigation is discontinued and 
regulatory authorities are notified. In addition, ICH E6 Section 4.9.5 states that the study records 
should be retained until an amount of time specified by applicable regulatory requirements or for a 
time specified in the Clinical Study Site Agreement between the investigator and sponsor.
Refer to the Phase 1 Site Specifications document for the sponsor’s requirements on record 
retention. The investigator should contact and receive written approval from the sponsor before 
disposing of any such documents.

(eg, age and weight) and the number and percentage of subjects within each category will be 
presented for categorical variables (eg, gender, ethnicity, and race).
Demographic variables of screen failure subjects and reasons for screen failures will be 
summarized for subjects who are screened, but not enrolled in the study. Individual demographic 
characteristics, date of informed consent, and reason for screen failure will be listed.
13.1.3 Pharmacokinetic Analysis
Descriptive statistics will be used to summarize serum concentrations of vedolizumab over each 
scheduled sampling time. Individual serum concentration-time data will be presented as listings. 
Descriptive statistics will be used to summarize serum PK parameters of vedolizumab. Individual 
serum PK parameters will be presented in a data listing.

Additional analyses may be performed as needed.
13.1.5 Safety Analysis
The number and percentage of subjects with treatment-emergent adverse events (TEAEs) defined 
as any AEs, regardless of relationship to study drug), AESIs for vedolizumab (ie, serious 
infections including opportunistic infection such as PML, liver injury, malignancies, 
infusion-related or systemic reactions and hypersensitivity and SAEs, which occur on or after 
dosing in patients, will be summarized by MedDRA system organ class, and preferred term 
overall, by severity, and by relationship to study drug. Separate summaries will also be generated 
for treatment-related AEs overall and by 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.

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator and institution guarantee access to source documents by the sponsor or its 
designee (CRO) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee, 
including but not limited to the Investigator’s Binder, study medication, subject medical records, 
informed consent documentation, documentation of subject authorization to use personal health 
information (if separate from the informed consent forms), and review of eCRFs and associated 
source documents. It is important that the investigator and other study personnel are available 
during the monitoring visits and that sufficient time is devoted to the process.
14.2
Protocol Deviations
The investigator should not deviate from the protocol, except where necessary to eliminate an 
immediate hazard to study subjects. Should other unexpected circumstances arise that will require 
deviation from protocol-specified procedures, the investigator should consult with the sponsor or 
designee (and IRB or IEC, as required) to determine the appropriate course of action. There will be 
no exemptions (a prospectively approved deviation) from the inclusion or exclusion criteria.
The site should document all protocol deviations in the subject’s source documents. In the event of 
a significant deviation, the site should notify the sponsor or its designee (and IRB or EC, as 
required). Significant deviations include, but are not limited to, those that involve fraud or 
misconduct, increase the health risk to the subject, or confound interpretation of primary study 
assessment. Significant protocol deviations will be entered into the eCRF, which is reviewed by 
the study sponsor or designee.
Every attempt will be made to collect each PK blood sample at the designated time point, and the 
actual time of each blood sample will be recorded on the source document and eCRF. Table 14.a
defines the windows allowed for sample collections. 
The Significant Protocol Deviation eCRF is to be completed for deviations that are identified the 
sponsor prior to the study. Protocol Deviation Forms are to be completed for PK samples collected 
outside of the following intervals:

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

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

Vedolizumab IV
Study No. Vedolizumab-1014
Page 58 of 81
Protocol Incorporating Amendment No. 02

CONFIDENTIAL
transfers, and disclosures of the subject’s personal and personal health information for purposes of 
conducting the study. The informed consent form and the subject information sheet (if applicable) 
further explain the nature of the study, its objectives, and potential risks and benefits, as well as the 
date informed consent is given. The informed consent form will detail the requirements of the 
participant and the fact that he or she is free to withdraw at any time without giving a reason and 
without prejudice to his or her further medical care.
The investigator is responsible for the preparation, content, and IRB or IEC approval of the 
informed consent form and if applicable, the subject authorization form. The informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) must 
be approved by both the IRB or IEC and the sponsor prior to use.
The informed consent form, subject authorization form (if applicable), and subject information 
sheet (if applicable) must be written in a language fully comprehensible to the prospective subject. 
It is the responsibility of the investigator to explain the detailed elements of the informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) to the 
subject. Information should be given in both oral and written form whenever possible and in the 
manner deemed appropriate by the IRB or IEC. In the event the subject is not capable of rendering 
adequate written informed consent, then the subject’s legally acceptable representative may 
provide such consent for the subject in accordance with applicable laws and regulations.
The subject, or the subject’s legally acceptable representative, must be given ample opportunity to: 
(1) inquire about details of the study and (2) decide whether or not to participate in the study. If the 
subject, or the subject’s legally acceptable representative, determines he or she will participate in 
the study, then the informed consent form and subject authorization form (if applicable) must be 
signed and dated by the subject, or the subject’s legally acceptable representative, at the time of 
consent and prior to the subject entering into the study. The subject or the subject’s legally 
acceptable representative should be instructed to sign using their legal names, not nicknames, 
using blue or black ballpoint ink. The investigator must also sign and date the informed consent 
form and subject authorization (if applicable) at the time of consent and prior to subject entering 
into the study; however, the sponsor may allow a designee of the investigator to sign to the extent 
permitted by applicable law.
Once signed, the original informed consent form, subject authorization form (if applicable), and 
subject information sheet (if applicable) will be stored in the investigator’s site file. The 
investigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed informed consent form, the signed subject authorization form 
(if applicable), and subject information sheet (if applicable) shall be given to the subject.
All revised informed consent forms must be reviewed and signed by relevant subjects or the 
relevant subject’s legally acceptable representative in the same manner as the original informed 
consent. The date the revised consent was obtained should be recorded in the subject’s medical 
record, and the subject should receive a copy of the revised informed consent form.

15.3
Subject Confidentiality
The sponsor and designees affirm and uphold the principle of the subject’s right to protection 
against invasion of privacy. Throughout this study, a subject’s source data will only be linked to 
the sponsor’s clinical study database or documentation via a unique ID 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 ID number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit its monitor or designee’s monitor, representatives from any 
regulatory authority (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs and IECs to review the subject’s original medical records (source data or 
documents), including, but not limited to, laboratory test result reports, ECG reports, admission 
and discharge summaries for hospital admissions occurring during a subject’s study participation, 
and autopsy reports. Access to a subject’s original medical records requires the specific 
authorization of the subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and/or advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with 
this section and the Clinical Study Site Agreement. In the event of any discrepancy between the 
protocol and the Clinical Study Site Agreement, the Clinical Study Site Agreement will prevail.
15.4.2 Clinical Trial Registration 
In order to ensure that information on clinical trials reaches the public in a timely manner and to 
comply with applicable laws, regulations, and guidance, Takeda will, at a minimum register 
interventional clinical trials it sponsors anywhere in the world on ClinicalTrials.gov or other 
publicly accessible websites before start of study, as defined in Takeda Policy/Standard. Takeda 
contact information, along with investigator’s city, state (for Americas investigators), country, and 

Vedolizumab IV
Study No. Vedolizumab-1014
Page 60 of 81
Protocol Incorporating Amendment No. 02

recruiting status will be registered and available for public viewing. For some registries, Takeda 
will assist callers in locating trial sites closest to their homes by providing the investigator name, 
address, and phone number to the callers requesting trial information. Once subjects receive 
investigator contact information, they may call the site requesting enrollment into the trial. The 
investigative sites are encouraged to handle the trial inquiries according to their established subject 
screening process. If the caller asks additional questions beyond the topic of trial enrollment, they 
should be referred to the sponsor. Any investigator who objects to Takeda providing this 
information to callers must provide Takeda with a written notice requesting that their information 
not be listed on the registry site.
15.4.3 Clinical Trial Results Disclosure 
Takeda will post the results of clinical trials on ClinicalTrials.gov or other publicly accessible 
websites, as required by Takeda Policy/Standard, applicable laws and/or regulations.
15.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the Clinical Study Site Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this policy, he or 
she should contact the sponsor or sponsor’s designee.

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 investigator agrees to assume the following responsibilities:
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, prior to 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 
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.
8. Ensure that requirements for informed consent, as outlined in ICH and local regulations, are 
met.
9. Obtain valid informed consent from each subject who participates in the study, and document 
the date of consent in the subject’s medical chart. Valid informed consent is the most current 
version approved by the IRB/IEC. Each informed consent form should contain a subject 
authorization section that describes the uses and disclosures of a subject’s personal 
information (including personal health information) that will take place in connection with the 
study. If an informed consent form does not include such a subject authorization, then the 
investigator must obtain a separate subject authorization form from each subject or the 
subject’s legally acceptable representative.
10. Prepare and maintain adequate case histories of all persons entered into the study, including 
eCRFs, hospital records, laboratory results, etc, and maintain these data for a minimum of 
2 years following notification by the sponsor that all investigations have been discontinued or 
that the regulatory authority has approved the marketing application. The investigator should 
contact and receive written approval from the sponsor before disposing of any such 
documents.

Collection, Storage, and Shipment of Bioanalytical Samples 
Instructions for Processing of Serum Samples for PK Vedolizumab Analysis 
1. Collect 5 mL of venous blood into a Becton-Dickinson Vacutainer or equivalent manufacturer. 
For all Vedolizumab samples, blood samples should be collected into red-stopper Vacutainers 
which contain no anticoagulant. Direct venipuncture is the preferred 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 (RCF) in a room temperature 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 (Vedolizumab-1014), matrix (ie, serum), PK assay, analyte (Vedolizumab), 
randomization 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 or lower. 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 the selected laboratory 
in China. “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 by the analytical laboratory.
Instructions for Processing of Serum Vedolizumab Samples Immunogenicity Testing
1. Collect 8.5 mL of venous blood into a Becton-Dickinson Vacutainer (Serum Separator Tube, 
red/gray top SST, catalog# 367988 or equivalent). Direct venipuncture is the preferred method 
of blood collection.
2. Invert sample 5 times immediately after the blood collection and allow the Vacutainer to sit at 
room temperature for approximately 30 minutes to ensure proper clot formation.
3. Centrifuge the sample at 1000 to 1300 x g for 10 to 15 minutes at room temperature to isolate 
serum.
a) For swing bucket rotors centrifuge samples for 10 minutes. 
b) For fixed-angle rotors centrifuge samples for 15 minutes. 
c) Refer to the centrifuge manual for proper operation of the centrifuge.

d) If using blood collection tubes other than BD Vacutainer Serum Separator Tube, follow the 
manufacturer’s recommended procedures
4. Remove serum using a transfer pipette and transfer:
a) 1.0 mL into the first 2 mL polypropylene cryovial. (Vial# 1)
b) 1.0 mL into the second 2 mL polypropylene cryovial. (Vial# 2)
c) 1.0 mL into the third 2 mL polypropylene cryovial. (Vial# 3)
d) Transfer any remaining serum into the fourth 2 mL polypropylene cryovial. (Vial# 4) 
5. Vial# 1 and vial #2 are the primary samples. Vial #3 and vial #4 are back up samples.
6. Cap the labeled cryovials and freeze the serum samples immediately at approximately -70°C or 
lower. No more than 1 hour and 45 minutes must be allowed to elapse between collecting 
blood and freezing the serum sample. 
7. If a -70°C freezer is not available, the samples may be stored at approximately -20°C in a 
commercial grade freezer with no auto-defrost until shipment to selected laboratory in China.
Shipping off Serum Samples for PK Analysis and Immunogenicity Testing for Vedolizumab

Appendix F
Detailed Description of Amendments to Text
The primary sections of the protocol affected by the changes in Amendment No. 02 are indicated. 
The corresponding text has been revised throughout the protocol. 
Change 1: Clarification for confirmation of entry criteria, including test results.
The primary change occurs in Section 7.0 SELECTION AND 
DISCONTINUATION/WITHDRAWAL OF SUBJECTS
Initial 
wording:
All entry criteria, including test results, need to be confirmed prior to first dose of 
study drug on Day 1.
Amended 
or new 
wording:
All entry criteria, including test results, need to be confirmed prior to first dose dosing
of study drug on Day 1.
Rationale for Change:
There is no change to the meaning of the sentence, just to avoid confusion since we only have one 
dose in the study.
Change 2: Clarification of the in-clinic diet.
The primary change occurs in Section 7.4 Diet, Fluid, Activity Control
Initial 
wording:
In the clinic, subjects will be provided 3 standard meals and 2 snacks per day, each 
meal containing approximately 30% fat (relative to the total calories).
Amended 
or new
wording:
In the clinic, subjects will be provided 3 standard meals and 2 snacks per day each 
meal containing approximately 30% fat (relative to the total calories). The menu of 
the standardized meals from the clinical research site needs to be approved by
Takeda before the implementation.
Rationale for Change:
This was revised based on the Site’s request per their standard practice for all studies in China
Change 3: Change in definition of timing for significant protocol deviation.
The primary change occurs in 7.5 Section Criteria for Discontinuation or Withdrawal of a Subject
Initial 
wording:
2. Significant protocol deviation. The discovery after the first dose of study 
medication that the subject failed to meet protocol entry criteria or did not adhere to 
protocol requirements, and continued participation poses an unacceptable risk to the 
subject’s health.

Amended 
or new 
wording:
2. Significant protocol deviation. The discovery after the first dose dosing of study 
medication that the subject failed to meet protocol entry criteria or did not adhere to 
protocol requirements, and continued participation poses an unacceptable risk to the 
subject’s health. 
Rationale for Change:
There is no change to the meaning of the sentence, just to avoid confusion since we only have one 
dose in the study.
Change 4: Revised Section 8.2 (Investigational Drug Assignment and Dispensing Procedures), to 
specify that the 3-digit Subject ID number will be used instead of 4-digit enrollment number.
The primary change occurs in Section 8.2 Investigational Drug Assignment and Dispensing 
Procedures
Initial 
wording:
Subjects will be assigned to receive a 4-digit enrollment number. The number will be 
assigned by the clinic site personnel in sequential order beginning with 1001. This 
4-digit number will be used by the clinical site to facilitate the prelabeling of PK 
samples, and will be the only subject identifier used on all PK sample collections. It 
should also be contained on the PK transport vials shipped to the bioanalytical 
laboratory, and will be used by the laboratory to report the subject data results. This 
4-digit number should only be used for the purposes described in this section. It does 
not replace the 3-digit subject number which is assigned at the time the informed 
consent is obtained and which is used for all other procedures to identify the subjects 
throughout the study.
Amended 
or new 
wording:
The 3-digit subject number which is assigned at the time the informed consent is 
obtained, will be assigned by clinic site personnel in sequential order and which 
is used for all other procedures to identify the subjects throughout the study, as 
well as to facilitate the prelabeling of PK samples, contained on the PK transport 
vials shipped to the bioanalytical laboratory, and will be used by the laboratory 
to report the subject data results.
Rationale for Change:
To specify that the 3-digit Subject ID number will be used to identify subjects, PK samples, and 
bioanalytical samples throughout study.

of blood urea nitrogen and carbon dioxide can be tested as an alternative to bicarbonate.
Change 6: Clarify timing of vital signs.
The primary change occurs in Section 9.1.5 Vital Sign Procedure
Initial 
wording:
Vital signs (temperature, respiration, pulse, and blood pressure) will be obtained at 
Screening, Check-in (Day -1), Day 1 (predose, and at 1 and 8 hours postdose), Days 2, 
8, 10(±1), 15 (±1), 29 (±2), 43(±2), 64 (±3), 85 (±3), 106 (±3), and Final Visit Day 
127(±3)/ET. For Days 1 and 2, heart rate and blood pressure will be measured after 5 
minutes supine and again at 1 and 3 minutes after standing. For Days 8, 10(±1), 15 
(±1), 29 (±2), 43(±2), 64 (±3), 85 (±3), 106 (±3) and Final Visit Day 127(±3)/ET, heart 
rate and blood pressure will be measured after 5 minutes supine only.
Amended 
or new 
wording:
Vital signs (temperature, respiration, pulse, and blood pressure) will be obtained at 
Screening, Check-in (Day -1), Day 1 (predose, and within ±5 minutes of 1 hour 
postdose and within ±30 minutes of 8 hours postdose), Days 2, 8, 10(±1), 15 (±1), 29 
(±2), 43(±2), 64 (±3), 85 (±3), 106 (±3), and Final Visit Day 127(±3)/ET. For Days 1 
and 2, heart rate and blood pressure will be measured after 5 minutes supine and again 
at 1 and 3 minutes after standing. For Days 8, 10(±1), 15 (±1), 29 (±2), 43(±2), 64
(±3), 85 (±3), 106 (±3) and Final Visit Day 127(±3)/ET, heart rate and blood pressure

will be measured after 5 minutes supine only.
Rationale for Change:
Several procedures need to be done at specific time points, like vital signs, PK blood sample 
collection, and ECG at 8h postdose. PK blood sample collection should be the first priority as this 
is a PK study, so we added a time window for vital signs procedures.
Change 7: Clarification of dosing.
The primary change occurs in Section 9.3.2 Study Entrance
Initial 
wording:
If the subject has satisfied all of the inclusion criteria and none of the exclusion criteria 
for study entrance, the subject should be assigned to treatment as described in 
Section 8.2. Subjects will be administered the first dose of study medication in the unit 
under the supervision of the investigator or designee, as described in Section 8.2.
Amended 
or new 
wording:
If the subject has satisfied all of the inclusion criteria and none of the exclusion criteria 
for study entrance, the subject should be assigned to treatment as described in 
Section 8.2. Subjects will be administered the first a dose of study medication in the 
unit under the supervision of the investigator or designee, as described in Section 8.2.
Rationale for Change:
There is no change to the meaning of the sentence, just to avoid confusion since we only have one 
dose in the study.
Change 8: Deletion of collection and storage of specimens for genome/gene analysis.
The primary change occurs in 9.4 Biological Sample Retention and Destruction
Initial 
wording:
In this study, specimens for genome/gene analysis will be collected as described. The 
genetic material will be preserved and retained for up to but not longer than 15 years 
or as required by applicable law. The sponsor has put into place a system to protect the 
subjects’ personal information to ensure optimal confidentiality and defined standard 
processes for sample and data collection, storage, analysis, and destruction.
Amended 
or new 
wording:
In this study, specimens for genome/gene analysis will be collected as described. The 
genetic material will be preserved and retained for up to but not longer than 15 years 
or as required by applicable law. The sponsor has put into place a system to protect the 
subjects’ personal information to ensure optimal confidentiality and defined standard 
processes for sample and data collection, storage, analysis, and destruction.

accurately described as approximately 38.5 mL and approximately 276 mL, respectively.
Change 10: Clarification of timing for when subjects are assessed for signs and symptoms of 
PML.
The primary change occurs in Section 11.1.1 Risk Minimization Action Program for PML (RAMP 
Program)
Initial 
wording:
The RAMP is focused on early clinical detection and management of that specific 
safety risk, including the discontinuation of study drug, if applicable. Subjects are 
assessed for signs and symptoms of PML prior to the administration of each dose of 
study drug using a PML subjective symptom checklist.
Amended 
or new 
wording:
The RAMP is focused on early clinical detection and management of that specific 
safety risk, including the discontinuation of study drug, if applicable. Subjects are 
assessed for signs and symptoms of PML prior to the administration of each dose of

Rationale for Change:
PML is the major AESI we are monitoring. After receiving the final dose of vedolizumab, all subjects should continue to check for 
symptoms of PML and inform the doctor if they have any symptoms of PML. The study doctor or nurse will call subjects 6 months after 
the dose of vedolizumab to ask a few questions about their health. The LTFU PML Wallet Card will not only help the subjects recognize 
the symptoms of PML but also help regular doctors become familiar with PML reporting process which is part of RAMP.
“X” should also be marked for Day 8 in order to be consistent with the footnote (c) specified under Table 9.2 of the protocol, which states 
“(c) Serum hCG pregnancy test will be done on all female subjects of childbearing potential at Screening, Check-in (Day -1), Day 8 and 
at Final Visit Day 127/ET.”
