STUDY SUMMARY
Name of Sponsor(s):
Millennium Pharmaceuticals, Inc.
Compound:
Vedolizumab IV
Title of Protocol:
An Open-Label, Dose-Finding Study of Vedolizumab IV 
Plus Standard of Care for Graft-Versus-Host Disease 
(GvHD) Prophylaxis in Patients Undergoing Allogeneic 
Hematopoietic Stem Cell Transplantation (HSCT)
IND No.:
127,634
EudraCT No.:
Not Applicable
Study Number: Vedolizumab-1015
Phase: 1b
Study Design:
This is a phase 1b, open-label, dose-finding study designed to evaluate the safety, tolerability, and clinical activity of 
adding vedolizumab to standard graft-versus-host disease (GvHD) prophylaxis (tacrolimus plus short-term 
methotrexate) in adult patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). 
Vedolizumab dose finding will be cohort based and follow a rule-based dose-finding study design with 
pharmacokinetic (PK) guidance. After a tolerated dose with acceptable PK has been identified, the cohort at that dose 
level may be expanded to further assess the tolerability and effectiveness of vedolizumab.
Eligibility will be determined during the Screening period, which may last for up to 28 days before Day –1
(designation of the day of the first IV infusion of vedolizumab). Patients who meet all eligibility criteria and provide 
written informed consent will be enrolled in this study. Study drug will be administered initially on Day –1 before 
allo-HSCT and then on Days +13 and +42 after allo-HSCT.
Approximately 36 evaluable patients will be enrolled in this study. For PK endpoints, an evaluable patient is one who 
receives vedolizumab and has at least 1 PK sample collected.
Patients who remain in remission will be followed for safety and development of acute and chronic GvHD for 1 year 
after allo-HSCT or until the patient’s death or withdrawal of consent or termination of the study by the sponsor. All 
patients will be followed for overall survival (OS) until death, withdrawal of consent, termination of the study by the 
sponsor, or for a maximum of 1 year after the last patient is enrolled in the study. Patients will attend a Day +100 visit 
(±7 days) at which time they will enter posttreatment follow-up.
Dose escalation will start with a low-dose cohort receiving vedolizumab at 75 mg IV on Day –1 and on Days +13 and 
+42 after allo-HSCT. HSC infusion should occur on Day 0 (no sooner than 12 hours after completion of IV infusion of 
vedolizumab on Day –1). The first patient in each dosing cohort will then be monitored for dose-limiting toxicities 
(DLTs) from the start of the first IV infusion of vedolizumab on Day –1 to Day +28 after allo-HSCT (the DLT 
observation period) including assessment for neutrophil recovery by Day +28. If the first patient in the first cohort 
tolerates vedolizumab IV at 75 mg and engraftment occurs, then 2 more patients will be enrolled in the first cohort. If 
none of the first 3 patients experience DLTs, the next cohort will receive vedolizumab 300 mg IV on Day –1 and on 
Days +13 and +42 after allo-HSCT. If the first patient in this cohort tolerates vedolizumab IV at 300 mg and 
engraftment occurs, then 2 more patients will be enrolled in the second cohort. If the first 3 patients at 300 mg tolerate 
the treatment without experiencing DLTs, then the decision on whether to increase the vedolizumab IV dose in the 
next cohort will be guided by the PK results. If 1 of the first 3 patients in the cohort experiences a DLT, then 3 
additional patients will be enrolled at the same dose level and monitored for DLTs from Day –1 until Day +28. If none 
of the additional patients experiences a DLT, then the decision on whether to increase the vedolizumab IV dose in the 
next cohort will be guided by the PK results. If 2 or more patients in a cohort of either 3 or 6 patients experience a 
DLT, then the dose of vedolizumab IV for the next cohort of 3 patients will be reduced. These patients will be 
monitored for DLTs in the same manner that patients in the previous cohort were monitored. 
After a tolerated dose level with acceptable PK has been identified in patients who are undergoing unrelated-donor 
myeloablative transplant for the treatment of hematologic malignancies, the cohort at that dose level may be expanded 
to include approximately 18 additional patients undergoing myeloablative conditioning or reduced-intensity 
conditioning (RIC) and are receiving either related or unrelated allo-HSCT for the treatment of hematologic 
malignancies or myeloproliferative neoplasms. This group of patients will allow the further assessment of the

tolerability and clinical activity of vedolizumab IV.
Vital signs, physical and neurological examinations, adverse event (AE) assessments, and laboratory values 
(chemistry, hematology, and urinalysis) will be obtained to evaluate the safety and tolerability of vedolizumab IV. To 
exclude patients with progressive multifocal leukoencephalopathy (PML), a Risk Assessment and Minimization for 
PML (RAMP) questionnaire will be administered at Screening and before vedolizumab IV administration on Days -1 
before allo-HSCT, and on Days +13 and +42 after allo-HSCT.
Serial blood samples for the evaluation of PK of vedolizumab will be obtained at prespecified time points. PK of 
vedolizumab will be analyzed for each of the first 3 patients at each dose level. It is expected that the 
concentration-time profile of vedolizumab will be influenced by the level of α4β7 target saturation. If α4β7 is saturated, 
then vedolizumab clearance would be linear; if α4β7is not saturated, then clearance would be nonlinear indicating rapid 
elimination. If the clearance of vedolizumab is nonlinear at the 300 mg dose, then subsequent dosing for all patients 
will be increased in approximately 150 mg increments (up to a maximum of 600 mg) until linear PK clearance is 
achieved.
Toxicity will be evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events 
(NCI CTCAE), Version 4.03, effective date 14 June 2010.
Primary Objective:
!
To describe the initial tolerability and safety and identify a recommended phase 2 dose of vedolizumab IV 
administered for GvHD prophylaxis along with standard GvHD prophylaxis therapy (tacrolimus plus short-term 
methotrexate) in patients undergoing allo-HSCT.
Secondary Objectives:
!
To characterize the PK of vedolizumab in patients on Days -1, +13, and +42 after allo-HSCT.
!
To determine the cumulative incidence and severity of acute GvHD at 100 days after allo-HSCT.
!
To determine the distribution of maximum severity of acute GvHD throughout the 100-day period after 
allo-HSCT.

Subject Population: Adult patients undergoing allo-HSCT for the treatment of hematologic malignancies or 
myeloproliferative neoplasms.
Number of Subjects:
Approximately 36 evaluable patients
Number of Sites: 
Approximately 3 to 4 in the United States
Dose Level(s):
Vedolizumab: initially 75 mg on Day –1 before allo-HSCT 
and on Days +13 and +42 after myeloablative allo-HSCT
Route of Administration:
Vedolizumab: intravenous (IV)
Duration of Treatment:
Patients will receive up to 3 doses of vedolizumab IV within 
the first 100 days after allo-HSCT.
Period of Evaluation:
Patients who remain in remission will be followed for 
safety and development of acute and chronic GvHD for 
1 year after allo-HSCT or until the patient’s death or 
withdrawal of consent or termination of the study by 
the sponsor. All patients will be followed for OS until 
death, withdrawal of consent, termination of the study 
by the sponsor, or for a maximum of 1 year after the 
last patient enrolled is enrolled in the study.
Additionally, subjects will be required to participate in 
a long-term follow-up (LTFU) safety survey 6 months 
after the last dose of study drug.
It is anticipated that this study will last for 
approximately 2 to 3 years.
Main Criteria for Inclusion:
In the initial cohort for dose finding, patients who are undergoing unrelated-donor myeloablative transplant for the 
treatment of hematologic malignancies and who are ≤60 years of age will be enrolled. After a recommended phase 2 
dose has been identified, the cohort at that dose level may be expanded to include additional patients receiving 
myeloablative conditioning or RIC (≤75 years of age) who are undergoing either related or unrelated allogeneic HSCT 
for the treatment of hematologic malignancies or myeloproliferative neoplasms.
Main Criteria for Exclusion:
Patients will be excluded from the study who have received prior allogeneic transplants or who are planned to undergo 
umbilical cord blood transplant, receive ex vivo T-cell-depleted hematopoietic stem cells (HSCs), receive any in vivo 
T-cell depleting antibodies, or RIC (in the dose-finding potion only). Patients with active cerebral/meningeal disease, 
active cytomegalovirus (CMV) colitis, or signs and symptoms of progressive multifocal leukoencephalopathy (PML) 
or any history of PML will also be excluded. In addition, patients with nonmalignant hematological disorders (eg, 
aplastic anemia, sickle cell anemia, thalassemias, Fanconi anemia) will be excluded in the both portions of the study.
Main Criteria for Evaluation and Analyses:
The primary endpoint of this study is to determine the recommended phase 2 dose of vedolizumab IV administered for 
GvHD prophylaxis along with standard GvHD prophylaxis therapy as assessed by the frequency of DLTs and the 
number and percentage of patients who experience treatment-emergent adverse events (TEAEs) or serious adverse 
events (SAEs) from administration of the first dose of vedolizumab IV through 18 weeks after administration of the 
last dose of vedolizumab IV. In addition, mean serum concentrations of vedolizumab will help inform the likelihood 
of α4β7 target saturation throughout the first 100 days following allo-HSCT.
Statistical Considerations:
Statistical analyses will be primarily descriptive and graphical in nature. No formal statistical hypothesis testing will 
be performed. A formal statistical analysis plan will be developed and finalized before database lock.

Sample Size Justification:
Approximately 18 evaluable patients will be enrolled to identify a tolerable vedolizumab dose level with acceptable 
PK. After the dose level has been identified, the cohort at that dose level may be expanded to include approximately 18 
additional patients receiving myeloablative conditioning or RIC who are undergoing either related or unrelated 
allo-HSCT for the treatment of hematologic malignancies or myeloproliferative neoplasms. This group of patients will 
allow the further assessment of the tolerability and clinical activity of vedolizumab IV. The sample size estimates are 
based on the primary objective of determining a recommended phase 2 dose and to describe the initial tolerability and 
safety of vedolizumab IV administered along with standard GvHD prophylaxis.

INTRODUCTION
4.1
Background
4.1.1
Disease Under Treatment
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an important therapy that is 
used to treat hematological malignant disorders and hematological genetic diseases, but its use is 
limited by the major complication of graft-versus-host disease (GvHD) [1]. The common 
complication of GvHD following an allo-HSCT is a major cause of morbidity and mortality. The 
risk of GvHD is variable and depends on patient factors, donor factors, the degree of 
histocompatibility between donor and recipient, the conditioning regimen, and the GvHD 
prophylaxis strategy employed [2-4]. In patients receiving hematopoietic stem cells from an 
unrelated donor source after myeloablative conditioning, the risk of Grade 2 to 4 acute GvHD is 
approximately 40% to 50% [2,3]. The reduction of GvHD without causing significant systemic 
immunosuppression may improve overall outcomes following allo-HSCT [2,5]. 
GvHD results from an activation of alloreactive donor lymphocytes by histocompatibility antigens 
on host antigen-presenting cells (APCs) [6,7]. It has been postulated that intestinal microflora and 
endotoxin exert a crucial step in APC activation, and that this process occurs in the gut-associated 
lymphoid tissues (GALT). Clinically, GvHD can be reduced through the use of T-cell depletion 
strategies and gut decontamination, highlighting the respective roles of both T cells and 
gastrointestinal (GI) microflora on the development of GvHD. In clinical HSCT, the human 
lymphocyte integrin α4β7 has been shown to be significantly increased on naïve and memory T 
cells in patients who subsequently developed intestinal acute GvHD compared with patients who 
developed skin acute GvHD or no GvHD [8]. Studies in murine models of acute GvHD suggest 
that prevention of T-cell trafficking to GALT via interruption of the interaction between α4β7 and 
mucosal addressin cell adhesion molecule-1 (MAdCAM-1) may prevent GvHD [9-11]. 
4.1.2
Vedolizumab IV
Vedolizumab (also called MLN0002) is a humanized immunoglobulin (Ig) G1 mAb directed 
against the human lymphocyte integrin 47. The 47 integrin mediates lymphocyte trafficking 
to GI mucosa and GALT through adhesive interaction with MAdCAM-1, which is expressed on 
the endothelium of mesenteric lymph nodes and GI mucosa [12-15]. Vedolizumab binds the 47 
integrin, antagonizing its adherence to MAdCAM-1 and as such, impairs the migration of gut 
homing leukocytes into GI mucosa. As a result, vedolizumab acts as a gut-selective 
immunomodulator [16]. Vedolizumab has been developed as a treatment for ulcerative colitis 
(UC) and Crohn’s disease (CD), which are characterized by inflammation of the GI tract.
Vedolizumab IV (Entyvio™) is a lyophilized solid which after appropriate reconstitution and 
dilution is intended for intravenous (IV) infusion that has been granted marketing approval in 
several regions, including the United States (US) and European Union (EU). Vedolizumab IV is 
approved for the treatment of adult patients with moderately to severely active UC or CD who 
have had an inadequate response with, lost response to, or were intolerant to a tumor necrosis 
factor-alpha (TNF-α) blocker or immunomodulator; or had an inadequate response with, were

intolerant to, or demonstrated dependence on corticosteroids. The approved dosing and 
administration regimen consists of 300 mg vedolizumab infused intravenously over approximately 
30 minutes at Weeks 0, 2, and 6, then once every 8 weeks (Q8W) thereafter. Previously conducted 
clinical studies in healthy subjects and patients with UC and CD have characterized the efficacy, 
safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and immunogenicity of 
vedolizumab.
4.1.2.1
Nonclinical
Several key nonclinical studies have been published that support the use of vedolizumab for the 
prevention of GvHD (see Section 4.1.1). Extensive nonclinical evaluations of the cardiovascular, 
acute, local tolerance, subchronic, chronic, immunologic, and reproductive toxicity of 
vedolizumab in pharmacologically responsive species (New Zealand white rabbits and 
cynomolgus monkeys) have been conducted and support its clinical development. Nonclinical 
studies also show that vedolizumab does not antagonize 4β1 integrin [16].
4.1.2.2
Human Experience
To date, more than 3400 subjects have received at least 1 dose of vedolizumab across all studies in 
the clinical development program (see current version of Investigator’s Brochure [IB]). Phase 3 
placebo-controlled studies enrolled 2427 subjects with UC or CD, of whom 1434 subjects were 
administered 300 mg of vedolizumab for induction followed by once every 4 weeks (Q4W) or 
Q8W for up to a total of 52 weeks and 488 subjects were administered 300 mg vedolizumab for 
induction only [17-19]. As of May 2015, 1786 subjects in clinical studies have been exposed to 
vedolizumab for ≥12 months, 1379 subjects for ≥24 months, 977 subjects for ≥36 months, 
724 subjects for ≥48 months, and 344 subjects for ≥60 months. Since approval in May 2014, the 
patient exposure of vedolizumab in the postmarketing setting as of May 2015 is estimated to be 
approximately 11,943 patient-years on the basis of drug shipment data.
In subjects with moderately to severely active CD (Study C13007), including subjects who had
failed treatment with 1 or more therapies including TNF-α antagonists, vedolizumab 300 mg 
infusion at Week 0 and Week 2 (induction) followed by either Q4W or Q8W from Week 6 through 
Week 52 (maintenance) demonstrated statistically significant differences in efficacy compared to 
placebo for both the induction phase and maintenance phase. The study met its primary endpoint 
for the induction phase, clinical remission at Week 6 but did not meet the second primary endpoint 
of enhanced clinical response (CDAI-100) at Week 6 in the overall population although the 
treatment difference favored vedolizumab. The study did meet its primary endpoint for the 
maintenance phase, clinical remission at Week 52, as well as important secondary endpoints, 
including enhanced clinical response at Week 52 and corticosteroid-free clinical remission at 
Week 52 [18].
In Study C13011, vedolizumab (300 mg infusion at Weeks 0, 2, and 6) was administered to 
subjects with moderately or severely active CD who had failed conventional therapies, including 
TNF-α antagonists. The primary endpoint of clinical remission at Week 6 in the TNF-α antagonist 
failure intent-to-treat population was not met; however, a treatment difference was observed at 

Vedolizumab IV
Study No. Vedolizumab-1015

CONFIDENTIAL
Week 10 in this population. Similar treatment differences favoring vedolizumab were also 
demonstrated for the overall population and in the subgroup of subjects who were TNF-α 
antagonist naïve [19].
Vedolizumab has shown an acceptable safety profile based on an analysis of safety data from both 
completed and ongoing studies (see current version of the IB). In phase 1 and 2 clinical trials 
(7 completed phase 1 studies in healthy subjects and 8 completed phase 1b/2 studies in UC or CD 
patients), there was no consistent evidence of any dose-toxicity relationships, and vedolizumab 
was well-tolerated. The majority of the safety data is from 3 well-controlled, phase 3 clinical 
studies that evaluated the safety of vedolizumab for up to 12 months in subjects with UC (Study 
C13006 [52 weeks]) or CD (Studies C13007 [52 weeks] and C13011 [10 weeks]). In addition, an 
interim assessment of safety was performed for the ongoing, uncontrolled extension study 
(Study C13008).
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 μg/mL with a serum terminal elimination half-life (t1/2z) of approximately 25 days. Thereafter, 
vedolizumab concentrations fell in a nonlinear fashion. Similar PK was observed in healthy 
subjects and in subjects with UC or CD.
Vedolizumab has shown an acceptable and consistent safety profile in clinical trials. In the pivotal 
phase 3 studies (Studies C13006 and C13007), the most common (≥5% and at a higher incidence 
than placebo) adverse reactions in subjects administered vedolizumab were nausea, 
nasopharyngitis, upper respiratory tract infection, arthralgia, pyrexia, fatigue, headache, and 
cough. Most serious adverse events have been related to exacerbations or complications of the 
underlying UC or CD. For those infections that were reported more frequently in 
vedolizumab-treated subjects, the sites of these infections correlated with the known tissue 
distribution of MAdCAM-1 binding sites. Anal abscess, abdominal abscess, and gastroenteritis 
were the most frequently reported serious infections. Extraintestinal infections (bronchitis, 
pneumonia, urinary tract infection, sepsis) occurred at a low frequency (∃1%). A total of 4% of 
vedolizumab-treated subjects and 3% of placebo-treated subjects experienced an infusion-related 
reaction. In Studies C13006 and C13007, 10% of subjects were positive for anti-vedolizumab 
antibodies 16 weeks following the last dose of vedolizumab. Results from the clinical program to 
date do not suggest an increased risk for malignancy with vedolizumab treatment. Overall, the 
safety profile following long-term treatment with vedolizumab in Study C13008 is consistent with 
safety in the completed studies. 
Concomitant use of corticosteroids and/or conventional immunomodulators did not appear to be 
associated with any increased rate of infections based on the comparative rates of infections in the 
phase 3 trials among subjects who had and had not received these medications.

Overall, vedolizumab was well tolerated in clinical studies.
4.2
Rationale for the Proposed Study
On the basis of the safety profile of vedolizumab that has been established in patients with 
inflammatory bowel disease (IBD), it is expected that vedolizumab will have acceptable 
tolerability in patients undergoing allo-HSCT because of the specific mechanism of action of 
vedolizumab. Prophylactic administration of vedolizumab to patients undergoing allo-HSCT may 
prevent trafficking of alloreactive T-cells to GALT and GI mucosa, thereby preventing the 
development of acute GvHD. 
Dose and Schedule
The starting dose and schedule of vedolizumab IV administration is 75 mg on Day –1 before 
allo-HSCT and on Days +13 and +42 after allo-HSCT. The first dose will be on Day –1 and the 
allo-HSCT will occur on Day 0, no sooner than 12 hours after completion of the IV infusion of 
vedolizumab to ensure distribution of vedolizumab and to minimize the likelihood of occurrence 
of infusion-related reactions at the time of HSC infusion. If none of the patients receiving 
vedolizumab IV at 75 mg experience dose-limiting toxicities (DLTs), dose escalation will 
continue to 300 mg on Day –1 before allo-HSCT and on Days +13 and +42 after allo-HSCT. A 
dose of 300 mg on Day –1 before allo-HSCT and on Days +13 and +42 is identical to the induction 
dose and schedule of vedolizumab approved for the treatment of UC or CD. 
The no-observed-adverse-effect level (NOAEL) in both pharmacologically responsive species 
(monkeys and rabbits) was 100 mg/kg vedolizumab IV. Collectively, nonclinical studies show that 
doses up to 100 mg/kg vedolizumab IV were well tolerated. This dose was associated with an 
exposure 26 times (rabbits) and 18 times (cynomolgus monkeys) higher than the geometric mean 
clinical area under the serum concentration-time curve [AUC] after a single dose of 300 mg 
vedolizumab IV by 30-minute infusion.
In addition, extensive clinical data exists in healthy volunteers and patients with IBD. 
Vedolizumab IV has been administered as both weight-adjusted doses (0.15-10.0 mg/kg) and 
fixed doses (180-750 mg). The PK of vedolizumab in healthy subjects and patients with UC or CD 
is described by a 2-compartment model with parallel linear and nonlinear elimination. Elimination 
of vedolizumab is linear at serum concentrations higher than 1 to 10 µg/mL, but nonlinear at lower 
serum concentrations [20,21]. The linear elimination kinetics suggest that the α4β7 target is 
saturated at serum concentrations greater than 10 µg/mL, but not saturated at lower serum 
concentrations in healthy subjects and patients with either UC or CD. In addition, serum 
concentrations of vedolizumab needed to provide efficacy in both UC and CD are greater than 
serum concentrations for full receptor occupancy [21]. Based on the 300 mg dose of vedolizumab 
IV administered once every 8 weeks in patients with UC or CD, the serum concentration of 
vedolizumab is expected to maintain >90% α4β7 receptor saturation over the dosing interval in 
>90% of subjects.
Unlike healthy subjects and subjects with UC or CD, subjects undergoing a myeloablative 
conditioning regimen [22] followed by allo-HSCT are expected to have markedly changing T-cell

populations with variable 47 integrin expression during the posttransplant period. The 
rule-based dose-finding strategy with PK guidance will ensure that the dose and schedule of 
vedolizumab selected for this patient population are well tolerated and effectively saturate the α4β7
target.
The mechanistic hypothesis for the prevention of GvHD requires sustained α4ß7-blockade at the 
time of hematopoietic stem cell infusion. Given the safety profile for the range of exposure for 
vedolizumab as noted previously, a dose of 300 mg would achieve sustained receptor saturation. 
The kinetics of vedolizumab established in patients with IBD suggest that the intended dosing 
schedule of vedolizumab will result in target saturation throughout the first 100 days following 
HSCT, which is the time period where the vast majority of acute GvHD occurs.

STUDY DESIGN
7.1
Overview of Study Design
This is a phase 1b, open-label, dose-finding study designed to evaluate the safety, tolerability, and 
clinical activity of adding vedolizumab to standard GvHD prophylaxis (tacrolimus plus short-term 
methotrexate) in adult patients undergoing allo-HSCT. Vedolizumab dose finding will be cohort
based and follow a rule-based dose-finding study design with PK guidance. After a tolerated dose 
with acceptable PK has been identified, the cohort at that dose level may be expanded to further 
assess the tolerability and effectiveness of vedolizumab.
Eligibility will be determined during the Screening period, which may last for up to 28 days before 
Day –1 (designation of the day of the first IV infusion of vedolizumab). Patients who meet all 
eligibility criteria and provide written informed consent will be enrolled in this study. Study drug 
will be administered initially on Day –1 before allo-HSCT and then on Day +13 and Day +42 after 
allo-HSCT.
Approximately 36 evaluable patients will be enrolled in this study. For PK endpoints, an evaluable 
patient is one who receives vedolizumab IV and has at least 1 PK sample collected.
Patients who remain in remission will be followed for safety and development of acute and chronic 
GvHD for 1 year after allo-HSCT or until the patient’s death or withdrawal of consent or 
termination of the study by the sponsor. Remission will be defined by conventional World Health 
Organization (WHO) criteria: <5% blast cells, count recovery (although complete remission with 
incomplete platelet recovery [CRp] would be allowed), and no evidence of extramedullary 
disease. All patients will be followed for OS until death, withdrawal of consent, termination of the 
study by the sponsor, or for a maximum of 1 year after the last patient is enrolled in the study. 
Patients will attend a Day +100 visit (±7 days) at which time they will enter posttreatment 
follow-up. Additionally, patients will be required to participate in a long-term follow-up (LTFU) 
safety survey 6 months after the last dose of study drug.
Dose escalation will start with a low-dose cohort receiving vedolizumab at 75 mg IV on Day –1 
before allo-HSCT and on Days +13 and +42 after allo-HSCT. HSC infusion should occur on 
Day 0 no sooner than 12 hours after completion of IV infusion of vedolizumab on Day –1. The 
first patient in each dosing cohort will then be monitored for DLTs from the start of the first IV 
infusion of vedolizumab on Day –1 until Day +28 (the DLT observation period) including 
assessment for neutrophil recovery by Day +28. If the first patient in the first cohort tolerates 
vedolizumab IV at 75 mg and engraftment occurs, then 2 more patients will be enrolled in the first 
cohort. If none of the first 3 patients experience DLTs, the next cohort will receive vedolizumab 
300 mg IV on Day –1 before allo-HSCT and on Days +13 and +42 after allo-HSCT. If the first 
patient in this cohort tolerates vedolizumab IV at 300 mg and engraftment occurs, then 2 more 
patients will be enrolled in the second cohort. If the first 3 patients at 300 mg tolerate the treatment 
without experiencing DLTs, then the decision on whether to increase the vedolizumab IV dose in 
the next cohort will be guided by the PK results. If 1 of the first 3 patients in the cohort experiences 
a DLT, then 3 additional patients will be enrolled at the same dose level and monitored for DLTs 
from Day –1 until Day +28. If none of the additional patients experiences a DLT, then the decision 

Vedolizumab IV
Study No. Vedolizumab-1015
Page 28 of 84
Protocol Incorporating Amendment No. 01

CONFIDENTIAL
on whether to increase the vedolizumab IV dose in the next cohort will be guided by the PK 
results. If 2 or more patients in a cohort of either 3 or 6 patients experience a DLT, then the dose of 
vedolizumab IV for the next cohort of 3 patients will be reduced. These patients will be monitored 
for DLTs in the same manner that patients in the previous cohort were monitored. 
After a tolerated dose level with acceptable PK has been identified in patients who are undergoing 
unrelated-donor myeloablative transplant for the treatment of hematologic malignancies, the 
cohort at that dose level may be expanded to include approximately 18 additional patients 
undergoing myeloablative conditioning or reduced-intensity conditioning (RIC) [22] and are 
receiving either related or unrelated allo-HSCT for the treatment of hematologic malignancies or 
myeloproliferative neoplasms. This group of patients will allow the further assessment of the 
tolerability and clinical activity of vedolizumab IV.
Vital signs, physical and neurological examinations, adverse event (AE) assessments, and 
laboratory values (chemistry, hematology, and urinalysis as specified in Section 10.3.13) will be 
obtained to evaluate the safety and tolerability of vedolizumab IV, as described in the Schedule of 
Events. To exclude patients with progressive multifocal leukoencephalopathy (PML), a Risk 
Assessment and Minimization for PML (RAMP) questionnaire will be administered at Screening
and before vedolizumab IV administration on Days -1 before allo-HSCT and on Days +13 and +42 
after allo-HSCT.
Serial blood samples for the evaluation of PK of vedolizumab will be obtained at prespecified time 
points as described in the Schedule of Events. PK of vedolizumab will be analyzed for each of the 
first 3 patients at each dose level. It is expected that the concentration-time profile of vedolizumab 
will be influenced by the level of α4β7 target saturation. If α4β7 is saturated, then vedolizumab 
clearance would be linear; if α4β7is not saturated, then clearance would be nonlinear indicating 
rapid elimination. If the clearance of vedolizumab is nonlinear at the 300 mg dose, then subsequent 
dosing for all patients will be increased in approximately 150 mg increments (up to a maximum of 
600 mg) until linear PK clearance is achieved.
Toxicity will be evaluated according to National Cancer Institute Common Terminology Criteria 
for Adverse Events (NCI CTCAE), Version 4.03, effective date 14 June 2010 [24]. DLTs are 
defined in Section 9.2.
See Figure 7.a for an overview of the study design from Days -1 to +50.

Patients in the dose-finding cohort who are withdrawn from treatment for reasons other than DLT 
during the DLT observation period will be replaced.
7.3
Duration of Study
Patients who remain in remission will be followed for safety and development of acute and chronic 
GvHD for 1 year after allo-HSCT or until the patient’s death or withdrawal of consent or 
termination of the study by the sponsor. All patients will be followed for OS until death, 
withdrawal of consent, termination of the study by the sponsor, or for a maximum of 1 year after 
the last patient is enrolled in the study.
It is anticipated that this study will last for approximately 2 to 3 years.

STUDY DRUG
9.1
Study Drug Administration
All protocol-specific criteria for administration of study drug must be met and documented prior to 
drug administration. Study drug will be administered only to eligible patients under the 
supervision of the investigator or identified subinvestigator(s).
The study sites will be supplied by the sponsor with the following medication in an open-label 
manner: vedolizumab IV 300 mg/vial, for single use, in 20-mL vials. The study medication will be 
provided in a glass vial as a lyophilized solid formulation for reconstitution using sterile water for 
injection. Each vial will be packaged in an appropriately labeled single vial carton. 
Each carton will have a single-panel booklet label that will contain, but will not be limited to the 
following: sponsor’s name and address, protocol number, packaging job/lot number, name and 
strength of the product, medication identification number, patient information, caution statement, 
directions for use, and storage conditions.
Additional reference information and administration instructions can be found in the Pharmacy 
Manual.
9.2
Definitions of Dose-Limiting Toxicity
Toxicity will be evaluated according to the NCI CTCAE, Version 4.03, effective 14 June 2010
[24]. These criteria are provided in the Study Manual. 
The DLT observation period in the proposed phase 1b study is defined as the start of the first IV 
infusion of vedolizumab on Day –1 to Day +28 after allo-HSCT.
A DLT will be any Grade 3 or higher toxicity assessed by the investigator as related to 
vedolizumab treatment. Hypersensitivity reactions and other infusion-related reactions will not be 
considered a DLT. Any patient who discontinues the study due to an infusion-related reaction will 
be replaced in the study.
Grade 4 or higher regimen-related organ toxicities (see Appendix H) will be considered as 
potential DLTs and reviewed as described in Section 12.0 before moving to the next dose level.
Grade 4 laboratory abnormalities that are not considered clinically significant by the investigator 
will not be considered DLTs. 
Engraftment will be defined as ANC >500/mm3 for 3 consecutive days or >2000/mm3 for 1 day. 
Failure to engraft by Day +28 will be considered a DLT. In the event of engraftment failure, the 
third dose of vedolizumab should be withheld. 
9.3
Dose Escalation Rules
The starting dose and schedule of vedolizumab IV administration is 75 mg on Day –1 before 
allo-HSCT and on Days +13 and +42 after allo-HSCT. If none of the patients receiving 
vedolizumab IV at 75 mg experience DLTs, dose escalation will continue to 300 mg on Day –1 
before allo-HSCT and on Days +13 and +42 after allo-HSCT. A dose of 300 mg on Day –1 before 

Vedolizumab IV
Study No. Vedolizumab-1015
Page 37 of 84
Protocol Incorporating Amendment No. 01
13 January 2016 
CONFIDENTIAL
allo-HSCT and on Days +13 and +42 is identical to the induction dose and schedule of 
vedolizumab approved for the treatment of UC or CD.
The first patient enrolled will be monitored for engraftment before the second patient is enrolled. 
The dose escalation will start with sentinel dosing for the first cohort, whereby the first patient will 
receive 75 mg vedolizumab IV administration along with standard-of-care tacrolimus and 
short-term methotrexate prophylaxis. The patient will then be monitored for DLTs from the start of 
the first IV infusion of vedolizumab on Day –1 to Day +28 after allo-HSCT (the DLT observation 
period) including assessment for engraftment by Day +28. If the first patient in the first cohort 
tolerates vedolizumab IV at 75 mg and engraftment occurs, then 2 more patients will be enrolled in 
the first cohort. If at any time during the study it appears that vedolizumab might lead to 
unacceptable engraftment delay or failure, then the study design might be revised so that 
vedolizumab prophylaxis is initiated approximately 1 week after hematopoietic stem cell infusion.
If none of the first 3 patients experience DLTs, the next cohort will receive vedolizumab 300 mg 
IV on Day –1 before allo-HSCT and on Days +13 and +42 after allo-HSCT. If the first patient in 
this cohort tolerates vedolizumab IV at 300 mg and engraftment occurs, then 2 more patients will 
be enrolled in the second cohort. If the first 3 patients at 300 mg tolerate the treatment without 
experiencing DLTs, then the decision on whether to increase the vedolizumab IV dose in the next 
cohort will be guided by the PK results. If 1 of the first 3 patients in the cohort experiences a DLT, 
then 3 additional patients will be enrolled at the same dose level and monitored for DLTs from Day 
–1 until Day +28. If none of the additional patients experiences a DLT, then the decision on 
whether to increase the vedolizumab IV dose in the next cohort will be guided by the PK results. 
Serial blood samples for the evaluation of PK of vedolizumab will be obtained at prespecified time 
points as described in the Schedule of Events. PK of vedolizumab will be analyzed for each of the 
first 3 patients at each dose level. It is expected that the concentration-time profile of vedolizumab 
will be influenced by the level of α4β7 target saturation in depots outside of the peripheral blood 
compartment. If α4β7 is saturated, then vedolizumab clearance will be linear; if α4β7is not 
saturated, then clearance will be nonlinear, indicating rapid elimination. If the clearance of 
vedolizumab is nonlinear at the 300 mg dose, then subsequent dosing for all patients will be 
increased in approximately 150 mg increments (up to a maximum of 600 mg) until linear PK 
clearance is achieved. Any dose escalation of vedolizumab IV will be cohort based. Intrapatient 
dose escalation of vedolizumab IV will not be permitted.
If 2 or more patients in a cohort of either 3 or 6 patients experience a DLT, then the dose of 
vedolizumab for the next cohort of 3 patients will be reduced to the dose level in the previous 
cohort or to an interim dose level. These patients will be monitored for DLTs in the same manner 
that patients in the first cohort were monitored. 
After a tolerated dose with acceptable PK has been identified, the cohort at that dose level may be 
expanded to include approximately 18 additional patients undergoing myeloablative conditioning 
or RIC and are receiving either related or unrelated allo-HSCT for the treatment of hematologic 
malignancies or myeloproliferative neoplasms. This group of patients will allow the further 
assessment of the tolerability and clinical activity of vedolizumab.

Excluded Concomitant Medications and Procedures
All prescription and over-the-counter medications, including influenza vaccines, taken by a patient 
as of the first study drug administration through 18 weeks from the last dose will be recorded on 
the designated case report form (CRF). Patients must be instructed not to take any medications, 
including over-the-counter medications and herbal supplements, without first consulting with the 
investigator.
The following medications and procedures are prohibited during the study:

Any investigational agent other than vedolizumab.

All live vaccines during study treatment and for at least 6 months after the last dose of study 
drug.

Either approved or investigational biological agents for the treatment of other conditions (eg, 
rheumatoid arthritis), other than localized injections (eg, intra-ocular injections for wet 
macular degeneration) or agents required for treatment of GvHD (and after consultation with 
the medical monitor).
9.5
Permitted Concomitant Medications and Procedures
Other medications considered necessary for the safety and wellbeing of the patient may be 
administered at the discretion of the investigator. Any concomitant medications added or 
discontinued during the study should be recorded on the electronic case report form (eCRF).
9.6
Precautions and Restrictions
9.6.1
HSC Source
A back-up plan for the event of primary graft failure must be identified for all patients in the study 
(ie, an alternate stem cell source) before performing the allo-HSCT.
9.6.2
Criteria for Dosing on Days +13 and +42 After Allo-HSCT
After a patient has received the first dose of vedolizumab IV on Day –1 before allo-HSCT, patients 
may not receive the second and/or third dose on Days +13 and +42 after allo-HSCT if they meet 
any of the following criteria:
1. The patient has a positive PML subjective checklist before the administration of study drug.
2. The patient has CMV colitis.
3. The patient has evidence of uncontrolled C. difficile colitis. 
4. The patient experienced an anaphylactic reaction to vedolizumab.
5. If female, the patient is pregnant.

9.6.3
Reproductive Effects
It is not known what effects vedolizumab has on human pregnancy or development of the embryo 
or fetus. Therefore, female patients participating in this study should avoid becoming pregnant, 
and male patients should avoid impregnating a female partner. Nonsterilized female patients of 
reproductive age group and male patients should use effective methods of contraception through 
defined periods during and after study treatment as specified in the following.
Female patients must meet 1 of the following:

Postmenopausal for at least 1 year before the screening visit, or

Surgically sterile, or

If they are of childbearing potential, agree to practice 2 effective methods of contraception 
from the time of signing of the informed consent form through 18 weeks after the last dose of 
study drug, or

Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of 
the subject. (Periodic abstinence [eg, calendar, ovulation, symptothermal, postovulation 
methods] and withdrawal are not acceptable methods of contraception.)
Male patients, even if surgically sterilized (ie, status postvasectomy) must agree to 1 of the 
following:

Practice effective barrier contraception during the entire study treatment period and through 
18 weeks after the last dose of study drug, or

Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of 
the subject. (Periodic abstinence [eg, calendar, ovulation, symptothermal, postovulation 
methods for the female partner] and withdrawal are not acceptable methods of contraception.)
9.7
Management of Clinical Events 
9.7.1
Hypersensitivity Reactions
Currently, there is no evidence to support the routine prophylactic administration of premedication 
(eg, antihistamines, corticosteroids) to patients receiving vedolizumab; hence such premedications 
are unlikely to be necessary or beneficial. At the discretion of the investigator, however, patients 
may be administered premedication prior to any study drug administration. Corticosteroids, if 
given as a premedication, should be limited to the day of administration. Vedolizumab 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. Patients should be observed during the infusion and until the infusion 
is complete.
Patients 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 drug, it should be 

Vedolizumab IV
Study No. Vedolizumab-1015

CONFIDENTIAL
immediately discontinued and the patient treated as medically appropriate. In the case of a mild 
reaction, study drug administration may be reinitiated (with appropriate premedication) at the 
discretion of the investigator. Patients 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 patients with less severe infusion-related reactions should be 
discussed with the project clinician.
9.7.2
Leukopenia or Lymphopenia
Leukocyte and lymphocyte counts will be monitored for all patients with a hematological panel 
(see Section 10.3.13). If engraftment has not occurred by Day +21 (defined as ANC >500/mm3 for 
3 consecutive days or >2000/mm3 for 1 day), the use of prophylactic myeloid growth factors (ie, 
granulocyte-colony stimulating factor [GCSF]) must be started with the product, dose, and route of 
administration at the discretion of the treating institution.
9.7.3
Cytomegalovirus Colitis
Regular assessments will include symptom-directed assessment for GI toxicity and weekly 
polymerase chain reaction (PCR) monitoring for CMV reactivation. Preemptive CMV therapy 
will be initiated per institutional standards for patients with CMV titers ≥500 copies/mL and rising 
on serial PCR. Subjects with active CMV colitis during screening will be excluded from the study, 
and subjects with confirmed CMV colitis during the study will require dosing hold. In patients 
suspected of having GvHD for whom the cause of transplantation-associated diarrhea and/or 
enterocolitis is unclear, the subject will require endoscopy and histologic analyses of intestinal 
biopsy specimens as clinically appropriate.
9.7.4
Malignancy
All cases of malignancies that are detected during the study, including relapse of primary disease 
will be reported as AEs.
9.7.5
Other Clinical Events
All patients will be screened for new neurological signs and symptoms potentially consistent with 
PML using the PML subjective symptom checklist (see Section 10.3.8) prior to dosing with 
vedolizumab. Any patients reporting signs or symptoms of PML will undergo objective testing. If 
a patient demonstrates a neurologic deficit related to PML upon administration of the specific 
test(s) on the Objective Checklist, no further doses of vedolizumab should be administered to that 
patient. The patient should be referred to the study neurologist for further testing and the sponsor 
must be notified of this action.
Subsequent doses of study drug will be administered only if the possibility of PML is definitively 
excluded, as described in the RAMP algorithm.

Dose Modification or Treatment Delay for Vedolizumab-Related Toxicity
Dosing of vedolizumab should be withheld for Grade 3 or higher vedolizumab-related toxicities. 
See Section 9.7 for management of vedolizumab dosing for specific clinical events. The medical 
monitor should be contacted prior to any dose modification in vedolizumab for any patient in the 
study.
9.9
Blinding and Unblinding
Not applicable. This is an open-label study. 
9.10
Description of Investigational Agent
Vedolizumab IV drug product is a sterile lyophilized solid formulation provided in a single vial, 
where each vial nominally contains 300 mg of vedolizumab antibody. Reconstituted 
vedolizumab IV drug product contains 60 mg/mL of active vedolizumab antibody, 50 mM 
histidine/histidine HCl, 125 mM arginine HCl, 100 mg/mL sucrose, and 0.6 mg/mL 
polysorbate 80, with a pH of 6.3.
Each vial will be reconstituted with sterile water for injection according to the instructions in the 
Pharmacy Manual.
9.11
Preparation, Reconstitution, and Dispensation
The investigational pharmacist will prepare the study treatment under standard aseptic conditions. 
For preparation of the active vedolizumab treatment, each vial of vedolizumab will be 
reconstituted according to the Pharmacy Manual with 4.8 mL of sterile water for injection. For the 
starting dose, 300 mg (5.0 mL) will be removed from each vial and diluted into 0.9% sodium 
chloride to an approximate volume of 250 mL. Additional details on the preparation of 
vedolizumab are provided in the Pharmacy Manual.
Because vedolizumab is a biological protein and, therefore, subject to denaturation upon shaking, 
reconstituted vials and IV solution bags should not be shaken. Vials are for single-use 
administration.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior 
to administration, whenever solution and container permit.
9.12

Blood samples (one 5-mL sample per scheduled time) for PK analysis of vedolizumab will be 
collected into red stopper vacutainers according to the schedule in the Pharmacokinetic Sample 
Breakdown table. Note: if done via peripheral vein, PK samples should not be collected from the 
arm where the vedolizumab infusion was administered. All PK samples should be collected within 
10% of nominal time; however, samples collected outside this margin will not be considered 
protocol deviations. Predose samples should be collected within 0.5 hours prior to the start of 
infusion and end of the infusion samples should be collected within 5 minutes from the end of 
infusion. The exact dates and times of administration of vedolizumab (start and end of infusion) 
and the exact date and times of collection of all PK samples will be recorded on the appropriate 
eCRF.

investigator or identified subinvestigator(s). The appropriate study personnel will maintain records 
of study drug receipt and dispensing.
10.9
Posttreatment Follow-up Assessments 
Patients will attend a Day +100 visit (±7 days) at which time patients will enter posttreatment 
follow-up. If subsequent anticancer therapy is required before 30 days after the last dose, the 
Day +100 visit should be conducted before the initiation of subsequent anticancer therapy.
Patients who remain in remission will be followed for development of acute and chronic GvHD 
and safety during clinic visits at 4, 5, 6, 9, and 12 months after allo-HSCT (Day 0) or until the 
patient’s death or withdrawal of consent or termination of the study by the sponsor.
All patients will be followed for OS until death, withdrawal of consent, termination of study by the 
sponsor, or for a maximum of 1 year after until the last patient is enrolled in the study. Survivor 
information may be collected by methods that include, but are not limited to, telephone, e-mail, 
mail, or retrieved from online or other databases (eg, social security indexes). 
NOTE: Related SAEs must be reported to the Global Pharmacovigilance department or designee. 
This includes deaths that the investigator considers related to study drug that occur during the 
posttreatment follow-up. Refer to Section 11.0 for details regarding definitions, documentation,

ADVERSE EVENTS
11.1
Definitions
11.1.1 Pretreatment Event Definition
A pretreatment event is any untoward medical occurrence in a patient or subject who has signed 
informed consent to participate in a study but before administration of any study medication; it 
does not necessarily have to have a causal relationship with study participation.
11.1.2 Adverse Event Definition
AE means any untoward medical occurrence in a patient or subject administered a pharmaceutical 
product; the untoward medical occurrence does not necessarily have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product whether or not it is related to the medicinal product. This includes any 
newly occurring event, or a previous condition that has increased in severity or frequency since the 
administration of study drug.
An abnormal laboratory value will not be assessed as an AE unless that value leads to 
discontinuation or delay in treatment, dose modification, therapeutic intervention, or is considered 
by the investigator to be a clinically significant change from baseline.
11.1.3 Serious Adverse Event Definition
SAE means any untoward medical occurrence that at any dose:

Results in death.

Is life-threatening (refers to an AE in which the patient was at risk of death at the time of the 
event. It does not refer to an event which hypothetically might have caused death if it were 
more severe).

Requires inpatient hospitalization or prolongation of an existing hospitalization (see 
clarification in the paragraph in Section 11.2 on planned hospitalizations).

Results in persistent or significant disability or incapacity. (Disability is defined as a 
substantial disruption of a person’s ability to conduct normal life functions).

Is a congenital anomaly/birth defect.

Is a medically important event. This refers to an AE that may not result in death, be 
immediately life threatening, or require hospitalization, but may be considered serious when, 
based on appropriate medical judgment, may jeopardize the patient, require medical or 
surgical intervention to prevent 1 of the outcomes listed above, or involves suspected 
transmission via a medicinal product of an infectious agent. Examples of such medical events 
include allergic bronchospasm requiring intensive treatment in an emergency room or at home, 
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the 

Vedolizumab IV
Study No. Vedolizumab-1015

CONFIDENTIAL
development of drug dependency or drug abuse; any organism, virus, or infectious particle 
(eg, prion protein transmitting transmissible spongiform encephalopathy), pathogenic or 
nonpathogenic, is considered an infectious agent.
In this study, intensity for each AE, including any lab abnormality, will be determined using the 
NCI CTCAE, Version 4.03, effective date 14 June 2010 [24]. Clarification should be made 
between an SAE and an AE that is considered severe in intensity (Grade 3 or 4), because the terms 
serious and severe are NOT synonymous. The general term severe is often used to describe the 
intensity (severity) of a specific event; the event itself, however, may be of relatively minor 
medical significance (such as a Grade 3 headache). This is NOT the same as serious, which is 
based on patient/event outcome or action criteria described above, and is usually associated with 
events that pose a threat to a patient’s life or ability to function. A severe AE (Grade 3 or 4) does 
not necessarily need to be considered serious. For example, a white blood cell count of 1000/mm3
to less than 2000 is considered Grade 3 (severe) but may not be considered serious. Seriousness 
(not intensity) serves as a guide for defining regulatory reporting obligations.
11.2
Procedures for Recording and Reporting Adverse Events and Serious 
Adverse Events
All AEs spontaneously reported by the patient and/or in response to an open question from study 
personnel or revealed by observation, physical examination, or other diagnostic procedures will be 
recorded on the appropriate page of the eCRF (see Section 11.3 for the period of observation). Any 
clinically relevant deterioration in laboratory assessments or other clinical finding is considered an 
AE. When possible, signs and symptoms indicating a common underlying pathology should be 
noted as 1 comprehensive event.
Regardless of causality, SAEs and serious pretreatment events (as defined in Section 11.1) must be 
reported (see Section 11.3 for the period of observation) by the investigator to the Takeda Global 
Pharmacovigilance department or designee (contact information provided below). This should be 
done by faxing the SAE Form within 24 hours after becoming aware of the event. The SAE Form, 
created specifically by Takeda, will be provided to each clinical study site. A sample of the SAE 
Form may be found in the Study Manual. Follow-up information on the SAE or serious 
pretreatment event may be requested by Takeda. SAE report information must be consistent with 
the data provided on the eCRF.
SAE Reporting Contact Information
Planned hospital admissions or surgical procedures for an illness or disease that existed before the 
patient was enrolled in the trial are not to be considered AEs unless the condition deteriorated in an 
unexpected manner during the trial (eg, surgery was performed earlier or later than planned).

For both serious and nonserious AEs, the investigator must determine both the intensity of the 
event and the relationship of the event to study drug administration. For serious pretreatment 
events, the investigator must determine both the intensity of the event and the relationship of the 
event to study procedures.
Intensity for each AE, including any lab abnormality, will be determined using the NCI CTCAE, 
Version 4.03, effective date 14 June 2010 [24]. The criteria are provided in the Study Manual.
Relationship to study drug administration will be determined by the investigator responding yes 
or no to this question: Is there a reasonable possibility that the AE is associated with the study 
drug?
11.3
Monitoring of Adverse Events and Period of Observation
AEs, both nonserious and serious, will be monitored throughout the study as follows:

AEs will be reported from the first dose of study drug through 18 weeks after administration of 
the last dose of study drug and recorded in the eCRFs.

Serious pretreatment events will be reported to the Takeda Global Pharmacovigilance 
department or designee from the time of the signing of the ICF up to first dose of study drug, 
but will not be recorded in the eCRF.

Related and unrelated SAEs will be reported to the Takeda Global Pharmacovigilance 
department or designee from the first dose of study drug through 18 weeks after administration 
of the last dose of study drug and recorded in the eCRF. After this period, only related SAEs 
must be reported to the Takeda Global Pharmacovigilance department or designee. SAEs 
should be monitored until they are resolved or are clearly determined to be due to a patient’s 
stable or chronic condition or intercurrent illness(es).
11.4
Procedures for Reporting Drug Exposure During Pregnancy and Birth Events
If a woman becomes pregnant or suspects that she is pregnant while participating in this study, she 
must inform the investigator immediately and permanently discontinue study drug. The sponsor 
must also be contacted immediately by faxing a completed Pregnancy Form to the Takeda Global 
Pharmacovigilance department or designee (see Section 11.2). The pregnancy must be followed 
for the final pregnancy outcome.
If a female partner of a male patient becomes pregnant during the male patient’s participation in 
this study, the sponsor must also be contacted immediately by faxing a completed Pregnancy Form 
to the Takeda Global Pharmacovigilance department or designee (see Section 11.2). Every effort 
should be made to follow the pregnancy for the final pregnancy outcome.
11.5
Procedures for Reporting Product Complaints
A product complaint is a verbal, written, or electronic expression that implies dissatisfaction 
regarding the identity, strength, purity, quality, or stability of a drug product. Individuals who

Product complaints in and of themselves are not AEs. If a product complaint results in an SAE, an 
SAE form should be completed and sent to 
 (refer to Section 11.2).
11.6
Risk Minimization Action Plan for PML (RAMP Program)
Natalizumab (TYSABRI), another integrin receptor antagonist, has been associated with PML, a 
rare and often fatal opportunistic infection of the central nervous system. PML is caused by the 
John Cunningham virus (JCV) and typically only occurs in patients who are immunocompromised 
[25,26]. MAdCAM-1 is mainly expressed on gut endothelial cells and plays a critical role in the 
homing of T lymphocytes to tissues within the GI tract, while VCAM-1 mediates trafficking to the 
central nervous system. Natalizumab is a pan-α4 integrin antagonist that binds to both the α4β1 and 
α4β7 integrins and inhibits cellular adhesion to VCAM-1 and MAdCAM-1 [27,28]. In contrast, 
vedolizumab binds to the α4β7 integrin only [16] and inhibits adhesion to MAdCAM-1, but not 
VCAM-1. Although no cases of PML have been reported in clinical trials with vedolizumab to 
date, a risk of PML cannot be ruled out.
Patients undergoing HSCT are immunocompromised because of underlying disease, prior 
therapies, HSCT conditioning, and GvHD prophylaxis and treatment. The baseline risk of PML in 
the population of patients undergoing allo-HSCT for the treatment of malignancy can be estimated 
at 35.4 per 100,000 person-years (95% CI: 0.90, 197.29) compared with 0.2 per 100,000 patients 
with autoimmune diseases who did not have HIV or malignancy (including patients with 
IBD).[29,30] To address the theoretical risk of the development of PML in patients treated with 
vedolizumab, the sponsor, with input from PML experts, has developed a Risk Minimization 
Action Plan for PML, the RAMP. The complete description of the RAMP program, including 
materials and instructions for its implementation and monitoring, is included in the Study Manual.
The RAMP is focused on early clinical detection and management of that specific safety risk, 
including the discontinuation of study drug, if applicable. Patients are assessed for signs and 
symptoms of PML prior to the administration of each dose of study drug using a PML subjective 
symptom checklist. Patients with a positive PML subjective symptom checklist at any time after 
enrollment in a vedolizumab clinical study will be evaluated according to a prespecified algorithm 
(the PML Case Evaluation Algorithm). The next dose of study drug will be held until the 
evaluation is complete and results are available. Subsequent doses of study drug will be 
administered only if the possibility of PML is definitively excluded, as described in the RAMP 
algorithm. An Independent Adjudication Committee (IAC) has been identified as part of the 
RAMP program to review new neurological signs and symptoms potentially consistent with PML, 
and will provide input regarding patient evaluation and management as defined in the IAC charter.

To ensure success of the RAMP program, site personnel will be trained to recognize the features of 
PML, and patients will be trained to report specific neurological signs and symptoms without 
delay. Educational materials for teaching site personnel and patients about PML and the RAMP 
procedures will be distributed to 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. Patients 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.

12.1
Dose Escalation and Cohort Expansion Plan
End-of-Cohort Meetings will be held to review safety and PK data before moving to the next dose 
level in subsequent cohorts. The safety review will encompass the following: all available AEs for 
DLTs, appropriate dosing information and patient eligibility/evaluability, dose-toxicity 
relationships, and any other pertinent available safety and PK data. The review committee for the 
End-of-Cohort Meetings will include the sponsor study team, the study investigators, and an 
independent, third-party HSCT expert consultant. The study sponsor team will include, but will 
not be limited to, the following: the study clinician, safety lead, and other members as appropriate 
(biostatistics, clinical pharmacology, and translational medicine to interpret PK, PD, and 
biomarker data). During the dose escalation and expansion phases, review of safety data by the 
above listed parties will occur as needed on the basis of continuous monitoring of safety data, but 
at least quarterly by the study sponsor team, with consideration of the study stopping criteria (see 
Section 14.2).

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the Data Management Plan. 
If selected for coding, AEs, PTEs, medical history, and concurrent conditions will be coded using 
the Medical Dictionary for Regulatory Activities (MedDRA). Drugs will be coded using the 
World Health Organization (WHO) Drug Dictionary.
13.1
eCRFs 
The sponsor or its designee will supply investigative sites with access to eCRFs and 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, CRO partners, and 
regulatory authorities. Investigative sites must complete eCRFs in English.
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. 
Any change of, modification of, or addition to the data on the eCRFs should be made by the 
investigator or appropriate site personnel. 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.
The principal investigator must review the eCRFs for completeness and accuracy and must sign 
and date the appropriate eCRFs as indicated. Furthermore, the principal investigator must retain 
full responsibility for the accuracy and authenticity of all data entered on the eCRFs.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by study monitors. The sponsor or its designee will be permitted to review the subject’s medical 
and hospital records pertinent to the study to ensure accuracy of the eCRFs. The completed eCRFs 
are the sole property of the sponsor and should not be made available in any form to third parties, 
except for authorized representatives of appropriate governmental health or regulatory authorities, 
without written permission of the sponsor.
13.2
Record Retention
The investigator agrees to keep the records stipulated in Section 13.1 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

STATISTICAL METHODS
14.1
Statistical and Analytical Plans
A statistical analysis plan (SAP) will be prepared and finalized prior to database lock. This 
document will provide further details regarding the definition of analysis variables and analysis 
methodology to address all study objectives.
A targeted data review will be conducted prior to database lock. This review will assess the 
accuracy and completeness of the study database, patient evaluability, and appropriateness of the 
planned statistical methods.
14.1.1 Analysis Sets
The populations used for analysis will include the following:

Safety population: The population of patients evaluable for vedolizumab safety is defined as 
all patients who receive any amount of study drug.

PK population: Defined as patients from the safety set with at least 1 PK sample collected. 

PD population: Defined as patients from the safety set with at least 1 PD sample collected.
For the primary endpoint, an evaluable patient is one who receives vedolizumab IV and is assessed 
for engraftment on or before Day +28.
14.1.2 Procedures for Handling Missing, Unused, and Spurious Data
All available safety, tolerability, efficacy, PK, and PD data will be included in data listings and 
tabulations. No imputation of values for missing data will be performed. The relevance of missing 
sample data will be assessed. 
Data that are potentially spurious or erroneous will be examined according to standard data 
management operating procedures.
14.1.3 Analysis of Demographics and Other Baseline Characteristics
Demographic (age, sex, and other parameters as appropriate) and baseline characteristics (weight, 
height, and other parameters, as appropriate) will be summarized by dose level.
14.1.4 Efficacy Analysis
Secondary efficacy endpoints include:

Percentage of patients who have developed overall Grade 2 to 4 acute GvHD (compiled from 
individual organ scores of gut, skin, or liver) by 100 days after myeloablative allo-HSCT.

The frequency by maximum severity of GvHD according to the modified Glucksberg criteria
and BMT CTN-modified IBMTR index.

14.1.5 Pharmacokinetic Analysis
Concentrations of vedolizumab will be summarized by dose level and by nominal time using 
descriptive statistics. Individual concentration-time profiles will be presented in data listings. PK 
parameters will be derived using standard noncompartmental methods. PK parameters of 
vedolizumab will be summarized using descriptive statistics. Other PK parameters may be 
calculated if necessary.
PK parameters will be summarized by dose level. A detailed plan will be provided in the SAP.
14.1.6 Pharmacodynamic Analysis 
14.1.7 Immunogenicity Analysis
Immunogenicity (anti-vedolizumab antibodies) will be descriptively summarized. The effect of 
anti-vedolizumab antibodies on safety and efficacy will be explored.
14.1.8 Safety Analysis
For the primary endpoint, an evaluable patient is one who receives vedolizumab IV and is assessed 
for engraftment on or before Day +28.
Safety will be evaluated by the incidence of AEs, severity and type of AEs, and by changes from 
baseline in the patient’s vital signs, weight, and clinical laboratory results using the safety analysis 
set. Exposure to study drug will be summarized and reasons for discontinuation will be tabulated. 
Safety will be summarized by dose level. 
TEAEs will be tabulated. Treatment-emergent is defined as any AE that occurs after 
administration of the first dose of study drug and up through 18 weeks after the last dose of study 
medication.
AEs will be tabulated according to MedDRA by system organ class, high-level terms, and 
preferred terms and will include the following categories:


Drug-related TEAEs.

Grade 3 or higher TEAEs.

Grade 3 or higher drug-related TEAEs.

The most commonly reported TEAEs (ie, those events reported by ≥10% of all patients).

SAEs.
Listings of PML checklist data and TEAEs resulting in study drug discontinuation will be 
provided.
Descriptive statistics for the actual values of clinical laboratory parameters (and/or change from 
baseline in clinical laboratory parameters) will be presented for all scheduled measurements over 
time. Mean laboratory values over time will be plotted for key laboratory parameters. Descriptive 
statistics for the actual values (and/or the change from baseline) of vital signs, weight, and blood 
pressure time will be tabulated by scheduled time point.
Shift tables for laboratory parameters will be generated based on changes in NCI CTCAE grade 
from baseline to the worst postbaseline value. 
Concomitant medications will be coded using the WHO Drug Dictionary. The number and 
percentage of patients taking concomitant medications will be tabulated by WHO drug generic 
term in the safety analysis set.
14.2
Interim Analysis and Criteria for Early Termination
No interim analysis is planned. Toxicities will be continuously monitored during all phases of the 
study.
In addition to ongoing safety reviews of cumulative data, early termination of the study will occur 
if any of the following are observed during the expansion phase of the study:

3 cases of CMV colitis, or

3 cases of engraftment failure; however, if first 2 cases of engraftment failure are in patients 
who received myeloablative conditioning, the study will be stopped.
14.3
Determination of Sample Size
Approximately 18 evaluable patients will be enrolled to identify a tolerable vedolizumab dose 
level with acceptable PK. After the dose level has been identified, the cohort at that dose level may 
be expanded to include approximately 18 additional patients receiving myeloablative conditioning 
or RIC who are undergoing either related or unrelated allo-HSCT for the treatment of hematologic 
malignancies or myeloproliferative neoplasms. This group of patients will allow the further 
assessment of the tolerability and clinical activity of vedolizumab IV.
The sample size estimates are based on the primary objective of determining a recommended 
phase 2 dose and to describe the initial tolerability and safety of vedolizumab IV administered 
along with standard GvHD prophylaxis.

QUALITY CONTROL AND QUALITY ASSURANCE
15.1
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator and institution guarantee access to source documents by the sponsor or its 
designee (CRO) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee 
(as long as blinding is not jeopardized), including but not limited to the Investigator’s Binder, 
study medication, subject medical records, informed consent documentation, documentation of 
subject authorization to use personal health information (if separate from the informed consent 
forms), and review of eCRFs and associated source documents. It is important that the investigator 
and other study personnel are available during the monitoring visits and that sufficient time is 
devoted to the process.
15.2
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.
15.3
Quality Assurance Audits and Regulatory Agency Inspections
The study site also may be subject to quality assurance audits by the sponsor or designees. In this 
circumstance, the sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the medication is stored and prepared, and any other facility used during the study. In 
addition, there is the possibility that this study may be inspected by regulatory agencies, including 
those of foreign governments (eg, the US Food and Drug Administration [FDA], the United 
Kingdom Medicines and Healthcare products Regulatory Agency, the Pharmaceuticals and 
Medical Devices Agency of Japan). If the study site is contacted for an inspection by a regulatory 
body, the sponsor should be notified immediately. The investigator and institution guarantee 
access for quality assurance auditors to all study documents as described in Section 15.1.

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.
16.1
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 American sites unwilling to provide names 
and titles of all members due to privacy and conflict of interest concerns should instead provide a 
Federal Wide Assurance Number or comparable number assigned by the Department of Health 
and Human Services.
The sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure, a copy of 
the informed consent form, and, if applicable, subject recruitment materials and/or advertisements 
and other documents required by all applicable laws and regulations, must be submitted to a 
central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the protocol and 
subject informed consent must be obtained and submitted to the sponsor or designee before 
commencement of the study (ie, before shipment of the sponsor-supplied drug or study specific 
screening activity). The IRB or IEC approval must refer to the study by exact protocol title, 
number, and version date; identify versions of other documents (eg, informed consent form) 
reviewed; and state the approval date. The sponsor will {ship drug/notify site once} the sponsor 
has confirmed the adequacy of site regulatory documentation and, when applicable, the sponsor 
has received permission from competent authority to begin the trial. Until the site receives 
[drug/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.

16.2
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.
16.3
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 16.2).
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 [e]CRF).
16.4
Publication, Disclosure, and Clinical Trial Registration Policy
16.4.1 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.

16.4.2 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. 
16.4.3 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.
16.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the Clinical Study Site Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this policy, he or 
she should contact the sponsor or sponsor’s designee.

Appendix B
Responsibilities of the Investigator
Clinical research studies sponsored by the sponsor are subject to ICH GCP and all the applicable 
local laws and regulations. The 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 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.

Revised Text
2. Candidates for HLA-matched or 1-locus (antigen or allele) mismatched unrelated or related 
donor allo-HSCT, using either peripheral blood stem cells or bone marrow as the cell source, 
for the treatment of hematologic malignancy or myeloproliferative neoplasm.
3. Disease must be in remission at the time of allo-HSCT. Remission is defined as one of the 
following:

Patients with acute leukemia, chronic myelogenous leukemia, and myelodysplasia with no 
circulating blasts and <5% blasts in the bone marrow.

Patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or other 
non-Hodgkin lymphoma with chemosensitive disease at time of transplantation.

Patients with myelofibrosis and other myeloproliferative neoplasms with <5% blasts in the 
blood and bone marrow.
Rationale for Amendment
As non-Hodgkin lymphoma is not classified as a myeloproliferative neoplasm, clarifications were 
made to the text to provide clarity based on the FDA communication received on 
28 December 2015.

considered a DLT. Any patient who discontinues the study due to an infusion-related reaction will 
be replaced in the study.
Revised Text
A DLT will be any Grade 3 or higher toxicity assessed by the investigator as related to 
vedolizumab treatment. Hypersensitivity reactions and other infusion-related reactions will not be 
considered a DLT. Any patient who discontinues the study due to an infusion-related reaction will 
be replaced in the study.
Rationale for Amendment
Regarding the DLT definition, a Grade 3 or higher toxicity assessed by the investigator as clearly
related to vedolizumab treatment was not acceptable according to the FDA communication 
received on 28 December 2015; thus, this was removed from the protocol text.
Page 44, Section 10.3.7 Vital Signs
Existing Text
Vital signs, including heart rate, respiratory rate, systolic and diastolic blood pressure, and 
temperature, will be recorded at the visits specified in the Schedule of Events. On dosing days, 
vital signs will be obtained before the infusion.
Revised Text
Vital signs, including heart rate, respiratory rate, systolic and diastolic blood pressure, and 
temperature, will be recorded at the visits specified in the Schedule of Events. On dosing days, 
vital signs will be obtained before and within 60 minutes of completion of infusion.
Rationale for Amendment
The recording of vital signs after study drug infusion was added on the basis of the FDA 
communication received on 28 December 2015. The change also appears in the Schedule of 
Events on Days –1, +13, and +42.
Page 54, Section 12.1 Dose Escalation and Cohort Expansion Plan
Existing Text
End-of-Cohort Meetings will be held to review safety and PK data before moving to the next dose 
level in subsequent cohorts. The review committee for the End-of-Cohort Meetings will include 
the sponsor study team, the study investigators, and a third-party HSCT expert consultant. During 
the expansion phase, review of safety data will occur at least quarterly with consideration of the 
study stopping criteria (see Section 14.2).
Revised Text
End-of-Cohort Meetings will be held to review safety and PK data before moving to the next dose 
level in subsequent cohorts. The safety review will encompass the following: all available AEs 
for DLTs, appropriate dosing information and patient eligibility/evaluability, dose-toxicity 
relationships, and any other pertinent available safety and PK data. The review committee for

the End-of-Cohort Meetings will include the sponsor study team, the study investigators, and an
independent, third-party HSCT expert consultant. The study sponsor team will include, but 
will not be limited to, the following: the study clinician, safety lead, and other members as 
appropriate (biostatistics, clinical pharmacology, and translational medicine to interpret 
PK, PD, and biomarker data). During the dose escalation and expansion phases, review of 
safety data by the above listed parties will occur as needed on the basis of continuous 
monitoring of safety data, but at least quarterly by the study sponsor team, with consideration 
of the study stopping criteria (see Section 14.2).
Rationale for Amendment
Language was added to clarify who is responsible for reviewing safety and PK data for the 
purposes of applying the dose escalation and early protocol stopping rules, and how often this 
review is to occur. These modifications were made on the basis of the FDA communication 
received on 28 December 2015.
