STUDY SUMMARY 
Name of Sponsor(s):
Takeda Development Center Americas, Inc.
Compound:
Vedolizumab for injection, for intravenous use
Title of Protocol: An Open-Label, Multicenter and Open 
Enrollment Model, Postmarketing, Milk-Only Lactation 
Study to Assess Concentration of Vedolizumab in Breast 
Milk of Lactating Women With Active Ulcerative Colitis or 
Crohn’s Disease Who are Receiving Vedolizumab 
Therapeutically
IND No.: 009125
EudraCT No.: N/A
Study Number: Vedolizumab-4001
Phase: 4
Study Design:
This is an open-label, multicenter and open enrollment model, milk-only postmarketing study to assess concentrations 
of vedolizumab in breast milk of lactating women with active ulcerative colitis (UC) or Crohn’s disease (CD) who are 
receiving vedolizumab therapeutically. Up to 12 (minimum of 10) lactating women with active UC or CD at least 18 
years old will be enrolled in this study. This is a milk-only lactation study with maternal milk sampling throughout the 
dosing interval, which allows detection of the presence of vedolizumab in milk of lactating women. No samples will 
be collected from the breast-fed infants in this study. Mothers must be exclusively breast-feeding their infants (or not 
providing more than 1 supplemental bottle of formula/day) when enrolled in this study.

At the approximately scheduled dosing time based on an established vedolizumab maintenance regimen, subjects will 
report to the clinic, study site, or other healthcare provider (HCP) office at Check-in (Day 1) and receive a 30-minute 
IV infusion. Subjects will remain at the clinic, study site, or other HCP office until after the Day 1 pharmacokinetic 
(PK) and safety assessments are completed. It is anticipated that visits on Days 4, 8, 15, or 29 may be completed in the 
subject’s home setting in the presence of a qualified nurse. To facilitate these visits, the subject should have access to 
a telephone. In most cases, home nurses performing a visit to a subject may complete study data forms that can be 
entered into the database by the contract research organization or site staff. In other cases, subjects may visit a clinic, 
study site, or other HCP office for assessments or to provide milk samples. The Study Exit/Follow-up safety 
assessment will occur on Day 57. The total duration on study for each subject will be approximately 3 months, 
including screening.

Number of Subjects:
Up to 12 (minimum of 10) lactating women with active UC or 
CD
Number of Sites: Approximately 7 to 10 sites
Dose Level(s):
300 mg vedolizumab IV (commercial drug)
Route of Administration:
IV infusion over 30 minutes
Duration of Treatment:
4 to 8 weeks (subject is on established vedolizumab 
maintenance therapy and received at least 1 dose of 300 mg of 
vedolizumab IV postpartum or has completed vedolizumab 
induction therapy [300 mg of vedolizumab IV at Week 0, Week 
2, and Week 6])
Period of Evaluation:
The total duration on study for each subject will be 
approximately 3 months, including Screening 
Main Criteria for Inclusion:
Subject is on established vedolizumab maintenance therapy and received at least 1 dose of 300 mg of vedolizumab IV 
postpartum or has completed vedolizumab induction therapy (300 mg of vedolizumab IV at Week 0, Week 2, and 
Week 6), which has been commenced by the subject’s treating physician for the treatment of active UC or CD prior to 
enrolling in this study. The subject has delivered a single, normal term infant (at least 37 weeks’ gestation) and 
lactation is well established in the subject. Mothers must be exclusively breast-feeding their infant (or not providing 
more than 1 supplemental bottle of formula/day) when enrolled in the study.
A complete list of inclusion criteria is provided in Section 7.1.
Main Criteria for Exclusion:
The subject has history of breast implants, breast augmentation, or breast reduction surgery.
A complete list of exclusion criteria is provided in Section 7.2. 
In addition, subjects may not use any excluded medications, supplements, or food products outlined in the protocol. 
Standard concomitant medications to be excluded are listed in Table 7.a.
Main Criteria for Evaluation and Analyses:
Pharmacokinetics:
Milk from each breast will be completely emptied using an electric milk pump at the specified time points (see table 
below) for the determination of vedolizumab concentrations in the milk. Milk collected from each breast at each time 
point will be pooled, and the total volume of milk collected and the starting and finishing time of each collection will 
be recorded. Two 5-mL aliquots of milk will be stored at -70°C until analysis of vedolizumab concentration by 
enzyme-linked immunosorbent assay (ELISA). Subjects with mastitis should not have milk samples collected until the 
infection is completely resolved. For milk sample collection on Days 4 through 57 (Days 4 through 29 for once every 
4 weeks [Q4W] vedolizumab therapy), sites are encouraged to schedule the visit at approximately the same time as the 
Day 1 postdose sampling time to reduce the effect of diurnal variation.

Safety: 
Safety parameters will include adverse events (AEs), physical examination findings, and vital signs. AEs will be 
recorded following administration of the vedolizumab and throughout the entire study thereafter. Vital signs will be 
recorded at Screening, Day 1 (predose, and at least 1 hour after the end of infusion), Days 4 (1), 8 (2), 15 (3), 
29 (3), and Study Exit/Follow-up (Day 57 [3]) or Early Termination. Vital signs will include oral body temperature 
measurement, blood pressure, respiration rate and pulse (beats per minute), measured after 5 minutes supine. 
A complete list of safety assessments is provided in Section 9.1.
Laboratory Tests: 
A urine pregnancy test will be performed during screening, Day 1and Study Exit/Follow-up Visit.
Statistical Considerations:
Pharmacokinetic Measures:
Concentrations of vedolizumab in milk will be summarized by scheduled time points using descriptive statistics. 
Individual milk concentration versus time data will be presented in a data listing. Milk PK parameters of vedolizumab, 
estimated daily infant dosage and percentage of maternal vedolizumab dose in breast milk will be summarized using 
descriptive statistics. Additional statistical analysis may be conducted, as appropriate.
Safety:
The number and percentage of subjects with treatment-emergent AEs (defined as any AEs, regardless of relationship 
to vedolizumab), AEs of special interest, and serious adverse events (SAEs), which occur on or after dosing in 
subjects, will be summarized by Medical Dictionary for Regulatory Activities system organ class, and preferred term 
overall, by severity, and by relationship to vedolizumab. Separate summaries will also be generated for 
treatment-related AEs overall and by severity. Baseline, postbaseline, and change from Baseline in vital signs will be 
summarized. Subjects with markedly abnormal values vital signs will be tabulated.
Sample Size Justification:
The sample size of 12 (minimum of 10) subjects is considered to be sufficient for this milk-only lactation study in 
women with active UC or CD who are being treated with vedolizumab. The sample size was not based on statistical 
power considerations.

INTRODUCTION
4.1
Background
Vedolizumab (also referred to as MLN0002 or Entyvio) is a humanized immunoglobulin G1 
monoclonal antibody (mAb) 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. Thus, vedolizumab 
acts as a gut-selective immunomodulator.
The effectiveness and safety of vedolizumab intended for intravenous (IV) use (vedolizumab IV, 
vedolizumab for injection, for intravenous use) for ulcerative colitis (UC) and Crohn’s disease 
(CD) have been established in pivotal phase 3 clinical studies in subjects who had not responded 
adequately to corticosteroids, immunomodulators, or tumor necrosis factor-alpha (TNF-α) 
antagonists. As of 19 November 2016, a total of 8 phase 1 studies in healthy subjects, 
8 phase 1b/phase 2 studies in subjects with UC or CD, and 3 phase 3 studies in subjects with UC or 
CD have been completed. Fourteen clinical studies are currently ongoing in the vedolizumab 
development program. 
As of 19 November 2016, approximately 4200 subjects (309 healthy subjects, 1811 subjects with 
UC, 2138 subjects with CD, 3 subjects undergoing allogenic hematopoietic stem cell 
transplantation (allo-HSCT), 1 subject with pouchitis, and 2 subjects with melanoma) have 
received at least 1 dose of vedolizumab across completed and ongoing company-sponsored 
interventional clinical studies. Vedolizumab exposure in interventional clinical studies 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. Approximately 450 subjects with UC or 
CD have received at least 1 dose of vedolizumab across ongoing company-sponsored 
noninterventional clinical studies. Based on drug shipment data as of 19 November 2016, the 
cumulative postmarketing patient exposure to vedolizumab IV globally is estimated to be 
approximately 77,382 patient-years.
Vedolizumab exhibits target-mediated drug disposition as characterized by linear and nonlinear 
processes of elimination after single-dose administration. Following IV dosing, vedolizumab 
concentrations fell in a biexponential fashion until concentrations reached approximately 1 to 
10 g/mL with a serum terminal elimination half-life (t1/2z) of approximately 25 days. Thereafter, 
vedolizumab concentrations fell in a nonlinear fashion.
Similar pharmacokinetics (PK) was observed in healthy subjects and in subjects with UC or CD. 
Results from population PK analyses suggest that while body weight and serum albumin are 
predictors of clearance, their effects are not considered clinically relevant. The PK of vedolizumab 
was similar in Japanese and Western subjects with UC. Vedolizumab PK was not affected by the 
coadministration of other immunosuppressive agents, including 6-mercaptopurine,

aminosalicylates, methotrexate, or azathioprine. As a mAb, the potential of vedolizumab to 
directly affect or be affected by cytochrome P-450 enzymes or transporters has not been tested.
Marketing approval has been granted in the United States, European Union, and multiple other 
countries for the treatment of adult patients with moderately to severely active UC or CD who have 
failed conventional therapy (ie, corticosteroids or immunomodulators) or 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
UC and CD are chronic, idiopathic, inflammatory conditions of the GI tract that peak in incidence 
during the reproductive years [5]. Therefore, the safety of medications to treat UC and CD during 
pregnancy and lactation is of significant interest to women patients of childbearing potential, as 
these medications may be transferred in utero or through breast milk from nursing inflammatory 
bowel disease (IBD) patients to their newborns [5]. Based on literature, mAbs, including selected 
TNF-α antagonists, are excreted in human milk; however, these antibodies in breast milk do not 
enter the neonatal and infant circulation in substantial amounts [6-10]. Low levels 
 of 
vedolizumab were detected on postpartum 
 in the milk 
 
treated with 
 of vedolizumab (
) 
dosed every  weeks; however, vedolizumab was not detected in the milk of any monkeys (n=7) 
treated with 
 It is unknown whether vedolizumab is present in 
human milk. 
The purpose of this postmarketing clinical study is to assess concentrations of vedolizumab in 
breast milk of lactating women with active UC or CD who have been on established vedolizumab 
IV maintenance treatment during the study period. This study is intended to fulfill the sponsor’s 
postmarketing commitment to conduct a milk-only lactation study as specified in the vedolizumab 
approvable letter from the Food and Drug Administration (FDA).

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is an open-label, multicenter and open enrollment model, postmarketing milk-only study to 
assess concentrations of vedolizumab in breast milk of lactating women with active UC or CD
who are receiving vedolizumab therapeutically. Up to 12 (minimum of 10) lactating women with 
active UC or CD who are at least 18 years old will be enrolled in this study. This study combines a 
traditional site-based approach and an open enrollment model to maximize enrollment and 
maintain efficiency and to meet local regulations. Where approved by the institutional review 
board (IRB), the open enrollment model may be implemented in addition to the traditional 
site-based approach.
Principal investigators (PIs) may be given the option to enroll and manage only subjects treated at 
their site (ie, traditional site) and/or to serve as a central PI (ie, provide oversight of subjects 
enrolled through the open enrollment model). The PIs are appropriately trained physicians who are 
responsible for providing oversight of the study, ensuring protocol adherence, and assessing safety 
of subjects and their infants enrolled in the study. Traditional sites are responsible for identifying 
eligible subjects from their institution, consenting/enrolling subjects, performing study 
procedures, coordinating home healthcare visits, assessing subjects’ safety, and collecting and 
entering data into the electronic case report form (eCRF).
In addition to the traditional site-based approach, having an open enrollment approach provides 
the opportunity for other eligible subjects to self-enroll if they reside outside of the geographic 
location of the traditional sites. Enrollment is facilitated by 
 Research Coordination Center 
(RCC) in the US. The RCC staff (who are formally trained in the appropriate methods for handling 
study procedures) coordinate enrollment and facilitate study management between: 
!
A subject enrolled using the open enrollment service.
!
The subject’s designated central site/investigator.
!
The subject’s healthcare providers (HCPs). 
!
The subject’s home healthcare nurses.
In the open enrollment model, eligible subjects are identified through awareness activities directed 
at the subject and her HCPs. The subject contacts 
 RCC for information about the study and, 
if interested in proceeding, answers prescreening questions. Interested eligible subjects provide 
written informed consent and medical release. The RCC assigns the subject to a central site/PI. The 
central PI, with the assistance of the RCC, will work with the subject and her HCP to assess 
eligibility. Screening activities are coordinated by the RCC through the subject’s local HCP, and 
the findings are shared with the central PI. The central PI will be responsible for directing the 
activities of the homecare nurse and will ensure that all adverse events (AEs) are properly assessed 
and reported and will provide oversight for the study. The central PI may also be serving as a 
traditional site PI.

Upon confirmation of eligibility at initial screening by the central PI, the RCC facilitates delivery 
of study-related materials (ie, electronic breast pump) to the subject. The RCC facilitates home 
visits with the designated local home healthcare agency. A breast pump and supplies for collecting 
the milk samples will be provided to the subject. Additional data collection and AE reporting in 
accordance with collection and reporting procedures described in Section 10.2 are facilitated by 
the RCC. The RCC provides ongoing assistance to the central site/investigator throughout the 
study.
This is a milk-only lactation study with maternal milk sampling throughout the dosing interval, 
which allows detection of the presence of vedolizumab in milk of lactating women. No samples 
will be collected from the breast-fed infants in this study. Mothers must be exclusively 
breast-feeding their infants (or not providing more than 1 supplemental bottle of formula/day) 
when enrolled in this study.
Subjects with an established vedolizumab maintenance regimen and have received at least 1 dose 
of 300 mg of vedolizumab IV postpartum or have completed vedolizumab induction therapy 
(300 mg of vedolizumab IV at Week 0, Week 2, and Week 6) will report to the clinic, study site, or 
other HCP office at Check-in (Day 1) and receive a 30-minute IV infusion of 300 mg vedolizumab 
at their approximately scheduled dosing time. Subjects will remain at the clinic, study site, or other 
HCP office until after the Day 1 PK and safety assessments are completed. It is anticipated that 
visits on Days 4 (±1), 8 (±2), 15 (±3), or 29 (±3) may be completed in the subject’s home setting in 
the presence of a qualified nurse. To facilitate these visits, the subject should have access to a 
telephone. In most cases, home nurses performing a visit to a subject may complete study data 
forms that can be entered into the database by the RCC or site staff. In other cases, subjects may 
visit a clinic, study site, or other HCP office for assessments or to provide milk samples. The Study 
Exit/Follow-up safety assessment will occur on Day 57 (±3). The total duration on study for each 
subject will be approximately 3 months, including Screening.

(not part of this study).
6.2
Justification for Study Design, Dose, and Endpoints
This study will assess concentrations of vedolizumab in breast milk of lactating women with active 
UC or CD who have been on established vedolizumab maintenance treatment and received at least 
1 dose of 300 mg of vedolizumab IV postpartum or have completed vedolizumab induction 
therapy (300 mg of vedolizumab IV at Week 0, Week 2, and Week 6) before enrolling in this
study. The dose selected in this study is the label recommended dose for treatment of patients with 
actively moderately or severely active UC or CD. Serial milk samples will be collected over the 
dosing interval (4 to 8 weeks) following the vedolizumab treatment to determine the PK 
parameters of vedolizumab in breast milk and to estimate the infant dosage on each sampling day, 
mean daily infant dosage over the dosing interval through breast milk, and percentage of maternal 
dose consumed in breast milk by the infants. During each sample collection time point, milk will 
be completely expressed from each breast and pooled before sampling to ensure the observed drug 
concentration in milk mimics the mean drug level during each feeding. The results of this study 
may be used to appropriately inform the Nursing Mother’s subsection of the labeling.

7.7
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 eCRF using the following categories. For screen failure 
subjects, refer to Section 9.1.14.
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.
2. Significant protocol deviation. The discovery after the first dose of study medication that the 
subject failed to meet protocol entry criteria or did not adhere to protocol requirements, and 
continued participation poses an unacceptable risk to the subject’s health.
3. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. 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 9.1.11.
7. Other.
Note: The specific reasons should be recorded in the “specify” field of the eCRF.
7.8
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 7.7. In addition, a subject may 
discontinue 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 
Early Termination Visit. Subjects discontinued or withdrawn from the study prior to Day 15 may 
be replaced if the sponsor decides it is necessary.

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, site personnel, or other HCP 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.
In the open enrollment model, 
 RCC will provide interested eligible subjects with the 
informed consent form (ICF) and medical release form. The central PI will contact the subject via 
phone to discuss the ICF and answer any questions the subject may have regarding the study. The 
RCC will send the subject a copy of the fully signed ICF once available. 
A unique subject identification 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 or age, sex, Hispanic ethnicity,
race as described by the subject, height, weight, alcohol use, reproductive status (including last 
menstrual period, lactation history, and failure to thrive of prior breast-fed infants) and smoking 
status of the subject at Screening. 
Medical history to be obtained will include determining whether the subject has any significant 
conditions or diseases relevant to the disease under study that stopped at or prior to signing of 
informed consent. Ongoing conditions are considered concurrent medical conditions (see 
Section 9.1.8).
Medication history information to be obtained includes any medication relevant to eligibility 
criteria stopped at or within 60 days prior to signing of informed consent.
9.1.3
Physical Examination Procedure
A physical examination will be performed at Screening, Day 1(baseline; defined as the assessment 
prior to first dose of vedolizumab), and Day 57/Early Termination/Follow-up (∀3). For subjects 
participating through open enrollment, the physical examination may be performed by the 
subject’s local HCP, and a record of that examination provided to the investigator as 
documentation. The physical examination will consist of the following body systems: (1) eyes; 
(2) ears, nose, throat; (3) cardiovascular system; (4) respiratory system; (5) gastrointestinal 
system; (6) dermatologic system; (7) extremities; (8) musculoskeletal system; (9) nervous system;

(10) lymph nodes; (11) other. All subsequent physical examinations should assess clinically 
significant changes from the assessment prior to first dose examination.
Any abnormal change from the baseline physical examination (Day 1 predose) must be assessed as 
not clinically significant or clinically significant by the investigator and recorded in the source 
document and eCRF.
On subsequent examinations, any abnormal change from the pretreatment physical examination 
assessment must be assessed as not clinically significant or clinically significant by the 
investigator and recorded in the source document and eCRF. Any clinically significant change or 
new diagnosis as a result of a clinically significant change, as determined by the investigator, will 
be recorded as an AE in source documentation and on the PTE/AE eCRF described in 
Section 10.0.
9.1.4
Weight and Height
A subject should have weight and height measured at Screening (weight only at Day 1) measured 
while wearing indoor clothing and with shoes off.
9.1.5
Vital Sign Procedure
Vital signs (oral temperature, respiration, pulse, and blood pressure) will be obtained at Screening, 
Day 1 (predose, and at least 1 hour after the end of the infusion), Days 4, 8, 15 and 29, and Study 
Exit/Follow-up (Day 57) or Early Termination and will be measured after 5 minutes supine.
Vital signs should be measured at the same time of the day across visits if possible. When vital 
signs are scheduled at the same time as milk collections, the milk collections will take priority.
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
Need for Rescue Medications
In this study, any new medication or any increase in dose of a baseline medication required to treat 
new or unresolved UC and CD symptoms (other than antidiarrheals for control of chronic 
diarrhea) is considered a rescue medication and must be recorded. Rescue medications should not 
be withheld if, in the opinion of the investigator, failure to prescribe them would compromise 
subject safety.

9.1.8
Documentation of Concurrent Medical Conditions
Concurrent medical conditions are those significant ongoing conditions or diseases that are present
at signing of informed consent. This includes clinically significant laboratory or physical 
examination abnormalities noted at screening examination. The condition (ie, diagnosis) should be 
described.
9.1.9
Procedures for Clinical Laboratory Samples
A urine pregnancy test (human chorionic gonadotropin [hCG]) will be performed at Screening, on 
Day 1 prior to dosing, and on Day 57 prior to the next scheduled dose.
9.1.10 Contraception and Pregnancy Avoidance Procedure
From signing of informed consent, throughout the duration of the study, (57 days after last dose of 
study medication), female subjects who are sexually active with a nonsterilized male partner** 
must use adequate contraception. In addition they must be advised not to donate ova or breast milk 
during this period.
*Females NOT of childbearing potential are defined as those who have been surgically sterilized 
(hysterectomy, bilateral oophorectomy or tubal ligation) or who are postmenopausal (eg, defined 
as at least 1 year since last regular menses with an FSH>40 IU/L or at least 5 years since last 
regular menses, confirmed before any study medication is implemented).
**Sterilized males should be at least 1 year postvasectomy and have confirmed that they have 
obtained documentation of the absence of sperm in the ejaculate.
An acceptable method of contraception is defined as one that has no higher than a 1% failure rate. 
In this study, where medications and devices containing hormones are excluded, the only 
acceptable methods of contraception are: 
Barrier methods (each time the 
subject has intercourse):
Intrauterine devices 
(IUDs):
Hormonal contraceptives 
(only Non-estrogen 
containing products 
allowed:

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.


understand the requirements for avoidance of pregnancy, donation of ova, during the course of the 
study.
During the course of the study, regular urine hCG pregnancy tests will be performed for women of 
childbearing potential and subjects will receive continued guidance with respect to the avoidance 
of pregnancy as part of the study procedures (Appendix A). In addition to a negative urine hCG 
pregnancy test at Screening, subjects also must have a negative urine hCG pregnancy test prior to 
receiving any dose of study medication. A urine hCG test will also occur at the Study Exit 
(Day 57)/Early Termination Visit.
9.1.11 Pregnancy
If any subject is found to be pregnant during the study, she will be withdrawn immediately and 
offered to enroll in the ongoing pregnancy registry.
All pregnancies will be followed up to final outcome, using the pregnancy form. The outcome, 
including any premature termination, should be reported to the sponsor. An evaluation after the 
birth of the child will also be conducted.
9.1.12 PML Checklist
Clinic staff, or other HCP, will administer the subjective PML checklist at the Screening Visit, 
prior to dosing on Day 1, and at the Study Exit/Follow-up (Day 57) or Early Termination Visit. 
Subjects will be provided a PML wallet card at Screening and at Study Exit/Follow-up or the Early 
Termination visit.
9.1.13 PK Sample/Milk Collection
9.1.13.1 Collection of Breast Milk for PK Sampling
Milk from each breast will be completely emptied using an electric milk pump at the specified time 
points according to Table 9.a for the determination of vedolizumab concentrations in the milk. 
Milk collected from each breast at each time point will be pooled, and the total volume of milk 
collected and the starting and finishing time of each collection will be recorded on the source 
document and eCRF. Two 5-mL aliquots of milk will be stored at -70°C until analysis of 
vedolizumab concentration by enzyme-linked immunosorbent assay (ELISA). Subjects with 
mastitis should not have milk samples collected until the infection is completely resolved. If 
mastitis is not resolved within the allowed window for sample collection, the sample should be 
collected at an unscheduled visit as close to scheduled time point as possible. If the unscheduled 
collection overlaps with the next scheduled time point, the missed sample collection should be 
skipped. For milk sample collection on Days 4 through 57 (Days 4 through Day 29, prior to next 
scheduled dose, for subjects on once every 4 weeks [Q4W] vedolizumab therapy), sites are 
encouraged to schedule the visit at approximately the same time as the Day 1 postdose sampling 
time to reduce the effect of diurnal variation. It is anticipated that visits on Study Days 4 (1), 
8 (2), 15 (3), or 29 (3) may be completed in the subject’s home setting in the presence of a 
qualified nurse. To facilitate these visits for milk sample collection, the subject should have access

to a telephone. In most cases, nurses performing a visit to a subject may complete study data forms 
that can be obtained and entered into the database by the RCC or site staff. In other cases, subjects 
may visit a qualified clinic, study site, or other HCP office to provide milk samples. Instructions 
for sample processing and shipping are provided in Appendix E. Additional instructions for 
homecare nurses will be provided in a separate manual.

(Day 57 [3] for Q8W regimen only) (prior to next scheduled dose).
9.1.13.2 Bioanalytical Methods
Milk concentrations of vedolizumab will be measured by a validated ELISA to measure 
vedolizumab concentrations. 
9.1.13.3 PK Parameters 
Milk PK parameters of vedolizumab will be derived using non-compartmental analysis methods. 
The PK parameters of vedolizumab will be determined from the concentration-time data for all 
evaluable subjects. Actual mid-point sampling times, rather than scheduled sampling times, will 
be used in all computations involving sampling times. The following PK parameters will be 
determined from concentrations of vedolizumab in milk: Cmax, AUCt, AUCτ, and tmax. The 
estimated daily infant dosage through breast milk on each sampling day, the mean daily infant 
dosage over the dosing interval and the percentage of weight-adjusted maternal dose consumed in 
breast milk may be calculated using the corresponding breast milk concentration(s) on the 
sampling day or AUCτ values and the standardized breast-fed infant milk consumption of 
150 mL/kg/day per FDA guidance on clinical lactation studies [11], as appropriate. Additional PK 
parameters may be calculated.

9.1.15 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.
9.2
Monitoring Subject Treatment Compliance
Study medication will be administered while subjects are under observation in the clinical research 
unit or other HCP office. 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

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 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).
Pre-existing conditions:

Pre-existing conditions (present at the time of signing of informed consent) are considered 
concurrent medical conditions and should NOT be recorded as PTEs or AEs. Baseline 
evaluations (eg, laboratory tests, ECG, x-rays) should NOT be recorded as PTEs unless related 
to study procedures. However, if the subject experiences a worsening or complication of such a 
concurrent 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

Vedolizumab IV

Protocol Incorporating Amendment No. 02
25 July 2017
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).

10.1.5 Special Interest AEs 
An adverse event of special interest (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 10.2.1.4 for information for special interest AE reporting. 
Special interest AEs for vedolizumab below should be reported to Takeda within 24 hours.
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

Start of AE collection: AEs must be collected from start of study medication administration. 
Property of Takeda: For non-commercial use only and subject to the applicable Terms of Use


Vedolizumab IV
Study No. Vedolizumab-4001
Page 43 of 77
Protocol Incorporating Amendment No. 02
25 July 2017

End of AE collection: AEs must be collected for 57 Days following the last dose of 
vedolizumab. 
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 Study Exit Visit (Day 57 
3 days after their dose of vedolizumab).
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.
AEs relating to the infant that are spontaneously reported should be collected and entered into the 
specific AE eCRF.
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. Severity.
4. Frequency.
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 AE Collection Involving Medically Anticipated Clinical Events 
CD and UC are associated with certain characteristic signs and symptoms including diarrhea, 
rectal bleeding, and abdominal pain that may be present at baseline and persist or fluctuate based 
on the individual subject’s disease history during the course of the study. These signs and 
symptoms will be collected as AEs. 
Exacerbations of disease activity (eg, increase in the daily amount of rectal bleeding or abdominal 
pain beyond the subject’s normal fluctuation, new signs and symptoms of CD and UC) will be 
collected as AEs and reported according to regulatory reporting requirements. 
Extra-intestinal manifestations of the subject’s disease (eg, arthralgia, arthritis, uveitis) that 
develop or worsen during the study are considered AEs. 
10.2.1.4 Special Interest AE Reporting
If this special interest AE, which occurs during the treatment period or the follow-up period, is 
considered to be clinically significant based on the criteria below, it should be recorded in the 
special interest AE eCRF or SAE Form. The Form should be completed and reported to the SAE 
reporting contact in Section 1.1 within 24 hours.
Hypersensitivity 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 vedolizumab administration. 
Corticosteroids, if given as a premedication, should be limited to the day of administration. 
Vedolizumab 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 
during the infusion and until the infusion is complete.
Subjects should be instructed to report the development of rash, hives, pruritus, flushing, urticaria, 
etc. that may represent an infusion-related reaction to study medication. If signs or symptoms of 
infusion-related reaction are observed during the administration of study, it should be immediately 
discontinued and the subject treated as medically appropriate. In the case of a mild reaction, 
vedolizumab administration may be reinitiated (with appropriate premedication) at the discretion 
of the investigator. Subjects with severe or serious infusion-related reactions (eg, stridor, 
angioedema, life-threatening change in vital signs) must be withdrawn from the study. 
In all cases of administration-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 vedolizumab administration may be considered as described in Section 10.1.12.
Malignancies
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 hepatotoxicity and PML, which are discussed in Sections 10.3
and 11.1.1, respectively. 
10.2.2 Collection and Reporting of SAEs
When an SAE occurs through the AE collection period it should be reported according to the 
following procedure:
A Takeda SAE eCRF or paper SAE Form must be completed, in English and signed by the 
investigator immediately or within 24 hours of first onset or notification of the event. The 
information should be completed as fully as possible but contain, at a minimum:

A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study medication(s).

Causality assessment.
The SAE eCRF should be completed within 24 hours of first onset or notification of the event. 
However as a back-up, if required the SAE Form should be completed and reported to Takeda 
Pharmacovigilance or designee within 24 hours to the attention of the contact listed in Section 1.1.
Any SAE spontaneously reported to the investigator following the AE collection period should be 
reported to the sponsor if considered related to study participation.
Reporting of Serious PTEs will follow the procedure described for SAEs.
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 applicable unexpected serious adverse drug 
reactions (SADRs) to regulatory authorities, including the European Medicines Agency, 
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, unexpected SADRs will be submitted to the 
regulatory authorities as expedited report within 15 days, 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 study. The investigator 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 data safety monitoring committee will be used in this study. 
11.1
Adjudication Committee 
A PML Independent Adjudication Committee (IAC) will be instituted for this study. The PML 
IAC will consist of a panel of leading PML experts, including a neurologist, neuroradiologist, and 
a virologist. 
11.1.1 Risk Assessment and Minimization for PML (RAMP Program)
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 Assessment and 
Minimization for PML, the RAMP program. The complete description of the RAMP program, 
including materials and instructions for its implementation and monitoring, is included in the 
Study Manual. The RAMP program is focused on early clinical detection and management of that 
specific safety risk, including the discontinuation of vedolizumab, if applicable. Subjects are 
assessed for signs and symptoms of PML prior to administration of vedolizumab using a PML 
subjective symptom checklist. Subjects with a positive PML subjective symptom checklist at any 
time after enrollment in a vedolizumab clinical study will be evaluated according to a prespecified 
algorithm (the PML Case Evaluation Algorithm). An IAC has been established as part of the 
RAMP program to review new neurological signs and symptoms potentially consistent with PML, 
and will provide input regarding 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.
12.1
CRFs (Electronic and Paper)
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.
Data collected by the subject’s HCP or homecare nurse will be recorded by the HCP or home nurse 
on the applicable study forms, home care worksheets, and source documents. The subject’s HCP 
or home nurse will send the original, completed documents to 
 RCC or the investigator/site 
via courier. If the original, completed documents are sent to 
 RCC, the RCC will send the 
documents to the investigator/site via courier. Site staff or 
 RCC will transcribe the data 
directly onto the 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.
After the lock of the clinical study database, any change of, modification of or addition to the data 
on the eCRFs should be made by the investigator with use of change and modification records of 
the eCRFs (Data Clarification Form) provided by the sponsor. The PI must review the data change 
for completeness and accuracy, and must sign, and date. 
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.

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 
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 Clinical Study Site Agreement for the sponsor’s requirements on record retention. The 
investigator should contact and receive written approval from the sponsor before disposing of any

accuracy and completeness of the study database, subject evaluability, and appropriateness of the 
planned statistical methods.
13.1.1 Analysis Sets
The safety analysis set will consist of all subjects who are enrolled and received 1 dose of 
vedolizumab. Subjects in this analysis set will be used for demographic, baseline characteristics 
and safety summaries.
The PK set will consist of all subjects who are enrolled and received 1 dose of vedolizumab and 
have at least 1 measurable milk concentration.
13.1.2 Analysis of Demographics and Other Baseline Characteristics
Demographic and baseline characteristics will be summarized for all subjects by treatment group. 
Summary statistics (number of subjects, mean, SD, median, minimum and maximum) will be 
generated for continuous variables (eg, age and weight) and the number and percentage of subjects 
within each category will be presented for categorical variables (eg, ethnicity, and race).
Demographic variables of screen failure subjects and reasons for screen failures will be 
summarized overall 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 PK Analysis
Concentrations of vedolizumab in milk will be summarized by scheduled time points using 
descriptive statistics. Individual milk concentration versus time data will be presented in a data 
listing. Milk PK parameters of vedolizumab, estimated daily infant dosage and percentage of 
maternal vedolizumab dose in breast milk will be summarized using descriptive statistics. 
Additional statistical analysis may be conducted, as appropriate.
13.1.4 Safety Analysis
All AEs will be coded by system organ class (SOC) and preferred term (PT) using MedDRA. A 
TEAE is defined as an AE with onset occurring within 57 days after vedolizumab administration. 
TEAEs will be listed and summarized. AEs with onset dates before the start of study medication or 
57 days after last dose of study medication will be listed, but they will not be included in the 
summary table.

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator and institution guarantee access to source documents by the sponsor or its 
designee (contract research organization) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee, 
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. A Protocol Deviation Form should be completed by the site and signed by the sponsor 
or designee for any significant deviation from the protocol.
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 FDA, the United Kingdom Medicines and Healthcare
products Regulatory Agency, the Pharmaceuticals and Medical Devices Agency of Japan). If the 
study site is contacted for an inspection by a regulatory body, the sponsor should be notified 
immediately. The investigator and institution guarantee access for quality assurance auditors to all 
study documents as described in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This study will be conducted with the highest respect for the individual participants (ie, subjects) 
according to the protocol, the ethical principles that have their origin in the Declaration of 
Helsinki, and the ICH Harmonised Tripartite Guideline for GCP. Each investigator will conduct 
the study according to applicable local or regional regulatory requirements and align his or her 
conduct in accordance with the “Responsibilities of the Investigator” that are listed in Appendix B. 
The principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
15.1
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable state and federal/local requirements 
of each participating region. The sponsor or designee will require documentation noting all names 
and titles of members who make up the respective IRB or IEC. If any member of the IRB or IEC 
has direct participation in this study, written notification regarding his or her abstinence from 
voting must also be obtained. Those Americas sites unwilling to provide names and titles of all 
members due to privacy and conflict of interest concerns should instead provide a Federal Wide 
Assurance Number or comparable number assigned by the Department of Health and Human 
Services.
The sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure, a copy of 
the informed consent form, and, if applicable, subject recruitment materials and/or advertisements 
and other documents required by all applicable laws and regulations, must be submitted to a 
central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the protocol and 
subject informed consent must be obtained and submitted to the sponsor or designee before 
commencement of the study (ie, before shipment of the sponsor-supplied drug or study specific 
screening activity). The IRB or IEC approval must refer to the study by exact protocol title, 
number, and version date; identify versions of other documents (eg, informed consent form) 
reviewed; and state the approval date. The sponsor will 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, 
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 identification number. As 
permitted by all applicable laws and regulations, limited subject attributes, such as sex, age, or date 
of birth, and subject initials may be used to verify the subject and accuracy of the subject’s unique 
identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit its monitor or designee’s monitor, representatives from any 
regulatory authority (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs and IECs to review the subject’s original medical records (source data or 
documents), including, but not limited to, laboratory test result reports, ECG reports, admission 
and discharge summaries for hospital admissions occurring during a subject’s study participation, 
and autopsy reports. Access to a subject’s original medical records requires the specific 
authorization of the subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and/or advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with 
this section and the Clinical Study Site Agreement. In the event of any discrepancy between the 
protocol and the Clinical Study Site Agreement, the Clinical Study Site Agreement will prevail.

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

(a) Conduct procedures for subjects discontinued early per Protocol Section 7.8. The PK sample should be collected at 
the Early Termination Visit, if possible. Study Exit/Follow-up visit should occur prior to subject receiving the 
subsequent, scheduled vedolizumab maintenance dose (not part of this study).
(b) Informed consent must be signed before any study-specific procedures are performed.
(c) All physical examinations are to be performed by the PI or subinvestigator at Screening, Day 1 (predose), and Day 
57 (±3)/Study Exit/Follow-up. Clinically significant findings on the physical examination that occur postdose of 
vedolizumab will be recorded as AEs. For subjects participating in open enrollment, the physical examination may be 
performed by the subject’s local HCP, and a record of that examination provided to the investigator as documentation.
(d) The PML checklist will be administered at screening, prior to dosing on Day 1 and Study Exit/Early Termination 
(ET)/Follow-up on Day 57.
(e) Vital signs (oral temperature, respiration, pulse, and blood pressure) will be obtained at Screening, on Day 1 
(predose and at 1 hours after the end of infusion), Days 4, 8, 15, and 29, and Study Exit/Follow-up (Day 57) or Early 
Termination) will be measured after 5 minutes supine.
(f) Height will only be collected at Screening.
(g) Record all ongoing medications from Screening and throughout the study.
(h) Urine pregnancy test will be performed at Screening, on Day 1 prior to dosing and on Day 57 prior to the next 
scheduled dose.
(i) Milk samples for PK analyses will be collected at predose (within 60 minutes prior to the start of infusion) and 
approximately 1 hour after the end of infusion on Day 1, and on Days 4, 8, 15, 29, and 57 (for Q8W regimen only), 
prior to the next scheduled dose). Subjects with mastitis should not have milk samples collected until the infection is 
completely resolved. Subjects unable to return to the clinic for Days 4, 8, 15, or 29 may have their milk samples 
collected at home by a qualified and trained homecare nurse.
(j) PTEs will be captured immediately following the signing of the informed consent at Screening. The routine 
collection of AEs will be captured from first dose of study drug and will continue until Study Exit/Early 
Termination/Follow-up. Any spontaneously reported AEs/SAEs will continue to be reported until Study Exit/Early 
Termination/Follow-up.

Appendix B
Responsibilities of the Investigator
Clinical research studies sponsored by the sponsor are subject to ICH GCP and all the applicable 
local laws and regulations. The responsibilities imposed on investigators by the FDA are 
summarized in the “Statement of Investigator” (Form FDA 1572), which must be completed and 
signed before the investigator may participate in this study.
The investigator agrees to assume the following responsibilities by signing a Form FDA 1572:
1. Conduct the study in accordance with the protocol.
2. Personally conduct or supervise the staff who will assist in the protocol.
3. Ensure that study related procedures, including study specific (non routine/non standard panel) 
screening assessments are NOT performed on potential subjects, prior to the receipt of written 
approval from relevant governing bodies/authorities.
4. Ensure that all colleagues and employees assisting in the conduct of the study are informed of 
these obligations.
5. Secure prior approval of the study and any changes by an appropriate IRB/IEC that conform to 
21 Code of Federal Regulations (CFR) Part 56, ICH, and local regulatory requirements.
6. 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.
7. Ensure that requirements for informed consent, as outlined in 21 CFR Part 50, ICH and local 
regulations, are met.
8. 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.
9. 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.
10. Allow possible inspection and copying by the regulatory authority of GCP-specified essential 
documents.

Collection, Storage, and Shipment of Bioanalytical Samples 
Instructions for Processing of Milk Samples for PK Analysis of Vedolizumab
1. Milk from each breast will be completely emptied using an electric milk pump at the specified 
time points for the determination of vedolizumab concentrations in the milk. Milk collected 
from each breast at each time point will be pooled, and the total volume of milk collected and 
the starting and finishing time of each collection will be recorded on the source document and 
eCRF. 
2. The pooled milk sample should be gently mixed and two aliquots of approximately 5.0 mL 
should be removed and placed into 2 appropriately labeled cryotubes.
3. Cryotube labeling may include protocol number (Vedolizumab-4001), sample matrix (ie, 
milk) subject ID, profile day and time, and either “SET 1” (for original sample) or “SET 2” (for 
duplicate sample).
4. Cap the labeled storage tubes and freeze the milk samples immediately at approximately -70°C 
or lower until shipment to
 On visit days 
when milk PK samples are collected by the subject’s HCP, or at the subject’s home by the 
homecare nurse, the HCP and homecare nurse will follow the instructions in the protocol 
and/or the homecare manual (or equivalent document) regarding sample collection, storage, 
and shipment.
Shipping of Milk Samples
The following instructions are recommended unless they differ from the site’s standard operating 
procedures for labeling, packaging, or shipping of pharmacokinetic samples.
1. Biological samples (ie, milk) should be shipped on dry ice to prevent thawing during transit. 
Samples should be shipped only on Monday, Tuesday, or Wednesday, and at least 2 days prior 
to a national holiday, in order to minimize the possibility of samples in transit over a weekend 
or holiday. If duplicate samples are to be shipped, send SET 1 samples and await confirmation 
of arrival before shipping the duplicate SET 2 samples.
a) SET 1 samples should be shipped directly to
, for analysis per protocol 
shipping instructions. 
b) When collected by the homecare nurse or HCP, duplicate samples (SET 2) are to be 
shipped to the study site for storage and shipment to 
per shipping 
instructions.
2. Before shipping, make sure the sample tubes are tightly sealed. Separate each subject’s 
samples as follows:
3. Separate the duplicate SET 2 samples from the SET 1 samples.
4. Place SET 1 samples for each subject into self-sealing bag (eg, Ziploc) containing additional 
absorbent material.

5. Using a permanent marker, write the subject ID, sample matrix (ie, breast milk), number of 
samples, and “SET 1” on each self-sealing bag.
6. Place the bags of individual subject’s samples into a larger plastic bag so that samples are 
double bagged. Duplicate SET 2 samples should be returned to the freezer for storage. Repeat 
steps 3 through 6 above when preparing duplicate samples for shipment, except self-sealing 
bags should be marked “SET 2.”
7. An inventory of individual samples should accompany each shipment and should include the 
Sponsor’s name (Takeda), study medication (Vedolizumab), protocol number 
(Vedolizumab-4001), investigator’s name, sample type (ie, milk), subject ID, nominal 
collection day and time, and intended sample storage conditions. When duplicate SET 2 
samples are being shipped, make a copy of the original SET 1 sample inventory and mark as 
“SET 2.” Place the inventory paperwork into a large self-sealing bag. 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. 
8. For sample packing, utilize dry ice generously (eg, 20-25 pounds per day of transit) to 
safeguard against longer than expected shipping times and delays. Use newspaper or other 
material to insulate the double-bagged samples from direct contact with the dry ice. Place the 
sample bundles into a Styrofoam container (or other suitable container) and fill the excess 
space with dry ice slabs or ice pellets (preferably the latter). Make a note of the estimated 
weight of the dry ice used per shipping container.
9. Place the inventory paperwork (in a large self-sealing bag) on top of the dry ice in the 
Styrofoam container. Place the lid on the Styrofoam container and seal completely with 
strapping tape. Place the Styrofoam container in a cardboard shipping carton and seal securely 
with strapping tape.
10. Mark the outside of shipping carton(s) with a tally number (eg, 1 of 5, 2 of 5).
11. The investigative site will ship samples to 
 using the lab carton (kit) provided.
12. When shipping samples to
affix an address label to each shipping carton. 
Complete the address label with the following information:

9.1.13 ECG Procedure
Standard 12-lead ECGs will be recorded at Screening and at Study Exit/Follow-up 
(Day 57 [3]) or Early Termination. Single ECGs will be taken at Screening and Day 
57 (3)/Early Termination visits. Additional unscheduled ECGs may be recorded 
where clinically necessary for subject safety.
When an ECG is scheduled at the same time as milk collection or vital signs then the 
milk collection and vital signs will take priority and the ECG will be obtained before 
or after the scheduled milk collection/vital sign assessment. If an ECG coincides with 
a meal, ECG will take precedence followed by the meal.
All stationary 12-lead ECG machines will be supplied by the site. Subjects should be 
in a supine position following an approximate 10-minute rest period for ECG 
recordings. Should technical difficulties occur during recording of the ECG, a 
reasonable attempt should be made to repeat the ECG shortly after the failed attempt. 
ECGs will be read automatically and also, the investigator or subinvestigator will 
manually interpret the ECG using 1 of the following categories: within normal limits, 
abnormal but not clinically significant, or abnormal and clinically significant. All 
12-lead ECGs will be stored for manual measurement of intervals, if necessary. 
Twelve-lead ECGs will be recorded using an ECG machine that automatically 
calculates the heart rate and measures PR interval, RR interval, QRS interval, QT

interval, QT interval with Fridericia correction method, and QT interval with Bazett 
correction method. 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 the source.
Rationale for Change:
There is no therapeutic intervention for this study, and subjects are on an established vedolizumab 
regimen. Enhanced monitoring by ECG is not required in the approved vedolizumab labeling.

requested by Takeda. The investigator will maintain a copy of the laboratory 
accreditation and the reference ranges for the laboratory used.
Laboratory reports must be signed and dated by the PI or subinvestigator indicating 
that the report has been reviewed and any abnormalities have been assessed for 
clinical significance.
All clinically significant laboratory abnormalities must be recorded as a PTE/AE in 
the subject’s source documents and on the appropriate eCRF. A clinically significant 
laboratory abnormality that has been verified by retesting will be followed until the 
abnormality returns to an acceptable level or a satisfactory explanation has been 
obtained.
If subjects experience ALT or AST >3×ULN, follow-up laboratory tests (at a 
minimum, serum alkaline phosphatase, ALT, AST, total bilirubin, -glutamyl 
transferase, and INR) should be performed within a maximum of 7 days and 
preferably within 48 to 72 hours after the abnormality was found.
Please refer to Section 7.7 for discontinuation criteria, and Section 10.3 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 
subject should return to their treating physician for management and additional testing 
and close monitoring. The abnormality should be recorded as an AE and follow-up 
information provided (please refer to Section 10.3 Reporting of Abnormal Liver 
Function Tests for reporting requirements).
