STUDY SUMMARY 
Sponsor: 
Takeda Pharmaceutical Company Limited 
Compound: 
MLN0002 
Study title: Phase 3, multicenter, randomized, double-blinded, 
placebo-controlled, parallel-group study to evaluate the 
efficacy, safety, and pharmacokinetics of intravenous 
MLN0002 (300 mg) infusion in induction and maintenance 
therapy in Japanese subjects with moderate or severe ulcerative 
colitis 
IND No.: 
Not Applicable 
EudraCT No.: 
Not Applicable 
Study Number: MLN0002/CCT-101 
Phase :3 
Study Design: 
This is a phase 3, multicenter, randomized, double-blinded, placebo-controlled, parallel-group study to evaluate the 
efficacy, safety, and pharmacokinetics of MLN0002 in induction and maintenance therapies in Japanese subjects with 
moderate or severe ulcerative colitis (UC). This study consists of the screening, induction and maintenance phases, 
and the open-label cohort. 
The screening phase involves screening tests of consenting subjects who visit a study site between 21 and 3 days 
before the start of treatment. Subjects meeting the eligibility criteria based on the inclusion and exclusion criteria on 
the first day of treatment (Day 1) will be enrolled into the induction phase. 
The induction phase consists of two cohorts and enrollment into Cohort 2 will start only after completion of 
enrollment into Cohort 1. Subjects enrolled into Cohort 1 will be randomized 1:2 to the placebo or MLN0002 group to 
receive the placebo or 300 mg of MLN0002 at Weeks 0, 2, and 6 in a double-blinded manner. Subjects enrolled into 
Cohort 2 will receive 300 mg of MLN0002 at Weeks 0, 2, and 6 in an unblinded manner. The primary efficacy 
endpoint in the induction phase will be evaluated at Week 10. 
Subjects showing a clinical response to the study drug at Week 10 will be enrolled into the maintenance phase at 
Week 14. Subjects who received the placebo in the induction phase will continue to receive the placebo at Weeks 14, 
22, 30, 38, 46, and 54 in a double-blinded manner. Subjects who received MLN0002 in the induction phase will be 
randomized 1:1 to the placebo or MLN0002 group, and will receive the placebo or 300 mg of MLN0002 at Weeks 14, 
22, 30, 38, 46, and 54 in a double-blinded manner. The primary efficacy endpoint in the maintenance phase will be 
evaluated at Week 60. 
Subjects not showing a clinical response to the study drug at Week 10 can be enrolled into the open-label cohort. 
Setting the enrollment day to the open-label cohort as Week 0x, those subjects will receive 300 mg of MLN0002 at 
Weeks 0x, 2x, 6x and then every 8 weeks thereafter for 46 weeks (minimum) to 94 weeks (maximum) in an unblinded 
manner. Subjects who experienced disease worsening or received rescue treatments during the maintenance phase, or 
those who completed Week 60 of the maintenance phase can be enrolled into the open-label cohort to receive the study 
drug in the same manner. Administration of MLN0002 will be terminated in all subjects at Week 46x of the last 
subject enrolled into the open-label cohort. 
The end-of-study examination will be performed at 16 weeks after the last dose in all subjects who received the study 
drug. In addition, the follow-up survey will be performed every 6 months from the last dose of the study drug up to 2 
years or until the date of marketing approval of the study drug, whichever comes earlier. 
Primary objective for the induction phase: 
To evaluate efficacy of MLN0002 in induction therapy in Japanese subjects with moderate or severe UC. 
Secondary objective for the induction phase: 
To evaluate safety of MLN0002 in induction therapy in Japanese subjects with moderate or severe UC. 
Primary objective for the maintenance phase: 
To evaluate efficacy of MLN0002 in maintenance therapy in Japanese subjects with moderate or severe UC.

Secondary objective for the maintenance phase: 
To evaluate safety of MLN0002 in maintenance therapy in Japanese subjects with moderate or severe UC. 
Subjects: Japanese subjects with moderate or severe UC 
Number of Subjects: 
Approximately 278 subjects in total. 
An initial cohort of 246 subjects (Cohort 1) will be randomized in the 
induction phase to receive MLN0002 (n=164) or the placebo (n=82). 
The number of subjects in Cohort 2 in the induction phase can be 
adjusted to provide the sample size (n=140) to be enrolled into the 
maintenance phase. The target number of subjects without a history of 
anti-TNFα antibody therapy is approximately 50% of the total. 
Number of Sites: 
Approximately 100 sites 
Dose Level(s): 
MLN0002 (300 mg) or the placebo will be administered by 
intravenous infusion at Weeks 0, 2, 6 and every 8 weeks thereafter. 
Route of Administration: 
Intravenous infusion (IV) 
Duration of Treatment: 
54 weeks (maximum 154 weeks) 
Period of Evaluation: 
70 weeks (maximum 170 weeks) 
The follow-up survey will be performed 
every 6 months from the last dose of the 
study drug for up to 2 years or until the date 
of marketing approval of the study drug, 
whichever comes earlier. 
Main Criteria for Inclusion: 
 
A subject aged 15 to 80 (inclusive) at the time of signing the informed consent. 
 
Subjects with diagnosis of total or left-sided UC based on the Revised Diagnostic Criteria for UC issued by 
“Research Group for Intractable Inflammatory Bowel Disease” Designated as Specified Disease by the Ministry 
of Health, Labor and Welfare (MHLW) of Japan (2012) at least 6 months before the start of administration of the 
study drug. 
 
A subject with moderately or severely active UC as determined by baseline complete Mayo score of 6 to 12

Safety endpoints: 
Adverse events (AEs), body weight, vital signs, electrocardiogram (ECG), clinical laboratory test (blood

Statistical analysis plan: 
(1) Statistical analysis in the induction phase 
The following descriptive calculations will be performed in the “Full Analysis Set in the induction phase (subjects 
randomized and received the study drug at least once in the induction phase).” 
For the primary efficacy analysis, “clinical response at Week 10” (primary endpoint of the induction phase) will be 
calculated by treatment group of the induction phase. Also clinical response at Week 10 will be calculated with 
stratification according to a history of anti-TNFα antibody therapy, and the comparison between treatment groups will 
be made with the Cochran-Mantel-Haenszel (CMH) test using a history of anti-TNFα antibody therapy as a 
stratification factor. The results of the primary analysis of the induction phase will be interpreted as below to 
determine the efficacy of MLN0002 induction therapy. 
 
The superiority of MLN0002 over the placebo on clinical response at Week 10 in the primary analysis of the 
induction phase is demonstrated when a statistically significant difference is observed in the clinical response at 
Week 10. 
For the secondary efficacy analysis, clinical remission at Week 10 will be calculated in the same manner as those in 
the primary analysis in the induction phase. The results of the secondary analysis will be interpreted as below to 
determine the efficacy of MLN0002 induction therapy. 
 
The superiority of MLN0002 over the placebo on clinical remission at Week 10 in the primary analysis of the 
induction phase is demonstrated when a statistically significant difference is observed in both the clinical 
response at Week 10 and clinical remission at Week 10. 
(2) Statistical analysis in the maintenance phase 
The following descriptive calculations will be performed in the “Full Analysis Set of the maintenance phase (subjects 
randomized and received the study drug at least once in the maintenance phase).” 
For the primary efficacy analysis, “clinical remission at Week 60” (primary endpoint of the maintenance phase)” will 
be calculated by treatment group of the maintenance phase. Also clinical remission at Week 60 will be calculated with 
stratification according to a history of anti-TNFα antibody therapy, and the comparison will be made with the 
Cochran-Mantel-Haenszel (CMH) test using a history of anti-TNFα antibody therapy as a stratification factor. The 
results of the primary analysis of the maintenance phase will be interpreted as below to determine the efficacy of 
MLN0002 maintenance therapy. 
 
The superiority of MLN0002 over the placebo on clinical remission at Week 60 in the primary analysis of the 
maintenance phase is demonstrated when a statistically significant difference is observed in the clinical 
remission at Week 60. 
(3) Significance level 
Since the study has different objectives in the induction and maintenance phases, no adjustments for multiplicity will 
be made between the analyses of the two phases, setting the significance level at 5% each. 
Sample size justification: 
On the basis of the findings from the phase 3 double-blinded, placebo-controlled study of MLN0002 in induction and 
maintenance therapy in non-Japanese subjects with moderate to severe UC (C13006), the clinical response at Week 10 
and clinical remission at Week 60 for MLN0002 and the placebo in this study was estimated to be 57.1% and 35.5%, 
and 43.3% and 15.9%, respectively. 
When the clinical response at Week 10 in the induction phase is analyzed using Pearson's chi-square test with 2-sided 
significance level of 5%, 164 and 82 subjects (at a ratio of 2:1, total 246 subjects) will be required respectively for the 
MLN0002 and placebo group to detect significance with a power of at least 90%. These numbers were therefore

selected as numbers of evaluable subjects of the primary endpoint of the induction phase (number of “subjects 
randomized in the induction phase and who received at least one dose of the study drug in the induction phase”). When 
the clinical remission at Week 10 in the induction phase is analyzed on these numbers of subjects, statistical 
significances in both the clinical response at Week 10 and clinical remission at Week 10 are detected with a power of 
69%. 
When the clinical remission at Week 60 in the maintenance phase is analyzed using Pearson's chi-square test with 
2-sided significance level of 5%, 42 subjects each for the MLN0002 and placebo group (total 84 subjects) will be 
required to detect significance with a power of at least 80%. Similarly, 55 subjects each (total 110subjects) will be 
required to detect significance with a power of at least 90%. These numbers were therefore selected as numbers of 
evaluable subjects of the primary endpoint of the maintenance phase (number of “subjects randomized in the 
maintenance phase and who received at least one dose of the study drugs in the maintenance phase”). Subjects enrolled 
into the maintenance phase include “those assigned to the placebo group in the induction phase” to maintain the 
blindness in the induction phase. To detect significance with a power of 80 and 90% for the analysis of the primary 
endpoint of the maintenance phase, therefore, 110 and 140 subjects will be respectively necessary for subjects 
randomized in the maintenance phase.

INTRODUCTION 
4.1 
Background 
Ulcerative Colitis (UC) is an inflammatory bowel disease repeatedly recur and remit. The lesion, 
involving the rectum toward the mouth sequentially, extends from the rectum through the colon at 
maximum. Specific symptoms are chronic viscous bloody stool or blood stool, and other 
symptoms including frequent diarrhea, abdominal pain, fever, anorexia or anemia. Frequent 
diarrhea limits going out, so that the Quality of Life (QOL) may deteriorate. 
Though etiology remains unknown yet, recent studies have revealed that breakdown of immune 
tolerance to intraluminal antigens including enterobacteria and abnormal cytokines may be a 
contributing factor. A curative treatment has not been established, therefore the medical approach 
intends basically to induce remission promptly to be maintained for a longer period (remission 
maintenance) with pharmacotherapy. The guidance of pharmacotherapy is provided in the Revised 
Guideline or Guidance[1] issued by Research Group for Intractable Inflammatory Bowel Disease 
Designated as Specified Disease by the MHLW of Japan, however treatment should be detailed 
based on disease types or severities. 
MLN0002 is a recombinant human immunoglobulin G1 monoclonal antibody[2] that specifically 
binds to human lymphocyte α4β7 integrin, and is currently being developed in UC and Crohn's 
disease (CD) inside/outside Japan. 
MLN0002 binds and inhibits α4β7 integrin, a cell membrane protein of lymphocytes, to bind its 
principal ligand of mucosal addressin cell adhesion molecule-1 (MAdCAM-1; a transmembrane 
glycoprotein markedly expressing on vascular endothelial cells in the high endothelial venule in 
the Peyer patch or the mesenteric lymph node and the arteriole in the intestinal lamina propria), 
leading to suppression of lymphocytes to migrate toward the intestinal mucosa and the gut-related 
lymphoid tissue[2]. From the above, MLN0002 is anticipated to exert efficacy with superior safety 
to conventional treatments or other biological drugs in UC and CD through suppression of 
intestinal inflammation by gastrointestinal tract-selective immunomodulatory effect not requiring 
systemic immunosuppression[3][4]. 
4.2 
Outcome of Clinical Studies 
Outside Japan, the following 4 Phase 3 studies (GEMINI Programs) were conducted in subjects 
with UC and CD in addition to the 14 Phase 1 and 2 studies. As of October, 2013, all studies were 
completed except a long-duration study in subjects with UC and CD (C13008), and applications 
have been submitted in Europe and US. In Japan, the Phase 1 study was conducted in subjects with 
UC.

4.2.1 
Summary of Outcome of Phase 1 and 2 Studies Outside Japan 
Major outcomes in Phase 1 and 2 studies conducted outside Japan were summarized below; 
• The pharmacokinetics of MLN0002 at the doses of 2 to 10 mg/kg was linear. The elimination 
half-life of MLN0002 was 15 to 22 days[5]. 
• The α4β7 receptors were saturated after the first dose at the doses of 2 to 10 mg/kg. Saturation 
of α4β7 receptors had been dose-dependently continued for several months after the last 
dose[5]. 
• It was suggested that the human anti-human antibody to MLN0002 (anti-MLN0002 antibody; 
hereinafter referred to as HAHA) may eliminate MLN0002 from the blood, resulting in 
decrease of MLN0002 exposure and loss of saturation of α4β7 receptors. HAHA emergence 
was dose-dependently decreased. 
• MLN0002 demonstrated superiority to the placebo in all subjects as clinical remission was 
32% at Week 6 in UC and 37% at Week 8 in CD[6][7]. The frequency of AEs was not 
significantly different from that in the placebo with no particular safety issues. 
4.2.2 
Summary of Outcome of Phase 3 Studies Outside Japan 
In all 3 Phase 3 studies conducted outside Japan (C13006, C13007 and C13011), 300 mg of 
MLN0002 or the placebo were administered. In C13006 study, superiorities were demonstrated to 
the placebo in the primary endpoints, i.e., the clinical response in the induction phase and the 
clinical remission in the maintenance phase[8]. Two primary endpoints were set in the induction 
phase of C13007 study. The difference in the clinical response in CD Activity Index (CDAI)-100 
was not significant, however superiority to the placebo was demonstrated in the clinical remissions 
each in the induction phase and the maintenance phase[9]. In C13011 study, superiority to the 
placebo was not demonstrated in the primary endpoint of the clinical remission at Week 6 in the 
sub-population of subjects who had failed with anti-TNFα antibodies (75% of all population), 
however the clinical remission at Week 6 in the whole population was significantly different from 
the placebo. In addition, the significant difference from the placebo in the clinical remission at 
Week 10 was observed both in the sub-population who had failed an anti-TNFα antibody and the 
whole population[10].

Furthermore, incidence of AEs and serious adverse events (SAEs) were not significantly different 
between the whole MLN0002 group and placebo group. Progressive multifocal 
leukoencephalopathy (PML) was not observed in any subjects in completed or ongoing clinical 
development programs. 
4.2.3 
Summary of Outcome of Phase 1 Study in Japan 
In Japan, the Phase 1 repeated-dose study in UC patients (CPH-001) was conducted to investigate 
safety, pharmacokinetics and pharmacodynamics of MLN0002 dosed at 150 or 300 mg in 
Weeks 0, 2 and 6. MLN0002 was well tolerated by the dose of 300 mg, and no injection site 
reaction or anaphylactic reaction was observed. In addition, serum MLN0002 concentration 
increased depending on dose ratio, and saturation of α4β7 receptors of the pharmacodynamic index 
was observed mostly continuously from the first dose[11]. 
4.3 
Rationale for the Proposed Study 
• In the 3 Phase 3 studies conducted outside Japan (C13006, C13007 and C13011), efficacy and 
safety of 300 mg of MLN0002 were investigated against the placebo each in the induction 
phase and the maintenance phase in moderate to severe UC or CD patients who had failed with 
the existing pharmacotherapy including anti-TNFα antibodies. As a result, significant 
difference from the placebo was observed in efficacy evaluation of MLN0002 in all studies. In 
addition, no particular issues were found in the safety evaluation. These results were consistent 
with the outcome obtained until Phase 2 studies. 
• In Japan, safety, serum MLN0002 concentration and saturability of α4β7 receptors were 
investigated in UC patients dosed with 150 or 300 mg of MLN0002 at Weeks 0, 2 and 6. The 
serum MLN0002 concentration resulted in similarity inside/outside Japan, and saturation of 
α4β7 receptors was observed mostly continuously from the first dose. In addition, no safety 
issues were found. 
From the above, the study was proposed as a Phase 3 study to investigate efficacy and safety of 
300 mg of MLN0002 in moderate to severe Japanese UC patients. 
Pharmacogenomic analysis may be conducted to evaluate contribution of genetic variance on drug 
response, for example, its efficacy and safety. Participation of study subjects in pharmacogenomic 
sample collection is optional. 
As pharmacogenomics is an evolving science, currently many genes and their function are not yet 
fully understood. Future data may suggest a role of some of these genes in drug response or 
diseases, which may lead to additional hypothesis-generating exploratory research on banked 
samples.

STUDY DESIGN AND DESCRIPTION 
6.1 
Study Design 
This is a phase 3, multicenter, randomized, double-blinded, placebo-controlled, parallel-group 
study to evaluate the efficacy, safety, and pharmacokinetics of MLN0002 in induction and 
maintenance therapies in Japanese subjects with moderate or severe UC. This study consists of the 
screening, induction, maintenance phases and open-label cohort. 
The screening phase involves screening tests of consenting subjects who visit a study site between 
21 and 3 days before the start of treatment. Subjects meeting the eligibility criteria based on the 
inclusion and exclusion criteria on the first day of treatment (Day 1) will be enrolled into the 
induction phase. 
The induction phase consists of two cohorts and enrollment into Cohort 2 will start only after 
completion of enrollment into Cohort 1. Subjects enrolled into Cohort 1 will be randomized 1:2 to 
the placebo or MLN0002 group1, and will receive the placebo or 300 mg of MLN0002 at Weeks 0, 
2, and 6 in a double-blinded manner. Subjects enrolled into Cohort 2 will receive 300 mg of 
MLN0002 at Weeks 0, 2, and 6 in an unblinded manner. The primary efficacy evaluation in the 
induction phase will be performed at Week 10. 
Subjects showing a clinical response to the study drug at Week 10 will be enrolled into the 
maintenance phase at Week 14. Subjects who received the placebo in the induction phase will 
continue to receive the placebo at Weeks 14, 22, 30, 38, 46, and 54 in a double-blinded manner. 
Subjects who received MLN0002 in the induction phase will be randomized 1:1 to the placebo or 
MLN0002 group2 to receive the placebo or 300 mg of MLN0002 at Weeks 14, 22, 30, 38, 46 and 
54 in a double-blinded manner. The primary efficacy endpoint in the maintenance phase will be 
evaluated at Week 60. 
Subjects not showing a clinical response to the study drug at Week 10 can be enrolled into the 
open-label cohort. Setting the enrollment day to the open-label cohort as Week 0x, those subjects 
will receive 300 mg of MLN0002 at Weeks 0x, 2x, 6x and then every 8 weeks thereafter for 46 
weeks (minimum) to 94 weeks (maximum) in an unblinded manner. Subjects who experienced 
disease worsening or received rescue treatments during the maintenance phase, or those who 
completed Week 60 of the maintenance phase can be enrolled into the open-label cohort to receive

Sample size is planned to be approximately 278 subjects in total, and 246 subjects (Cohort 1) will 
be randomized in the induction phase to receive MLN0002 (n=164) or the placebo (n=82). The 
number of subjects in Cohort 2 in the induction phase can be adjusted so that the planned sample

6.2 
Justification for Study Design, Dose, and Endpoints 
6.2.1 
Justification for Study Population 
The Guideline for Treatment of UC[1] issued by “Research Group for Intractable Inflammatory 
Bowel Disease Designated as Specified Disease” by the MHLW of Japan (2012) recommends oral 
salazosulfapyridines or 5-ASAs in principle, or suppositories/enemas of corticosteroids, 
suppositories of salazosulfapyridines and enemas of 5-ASAs for remission induction therapy in 
mild to moderate UC patients. In addition, oral corticosteroids are recommended for patients who 
inadequately respond to the above treatments or severe patients. 
The intractable patients is defined as those whose response is inadequate despite proper usage of 
corticosteroids (corticosteroid resistance), or those who experienced recurrence/worsening with 
dose reduction of corticosteroids while symptoms had been stable during use of corticosteroids 
(corticosteroid dependence). Whereas immunomodulators or anti-TNFα antibodies are 
recommended for these intractable patients, non-responders to these drugs or loss of response

during the course of treatment are still problematic. MLN0002, having a different mode of action 
from existing therapeutic drugs, has been suggested to be efficacious in such patients by outcome 
from studies outside Japan. 
From the above, the study population in the induction phase in the study was set as moderate to 
severe Japanese UC patients who had failed with existing pharmacotherapy (either of 
corticosteroids/immunomodulators/anti-TNFα antibodies) 
6.2.2 
Justification of Study Design and Sample Size 
The Guideline for Treatment of UC[1] recommends that the remission maintenance therapy 
should apply to prevent recurrence after achievement of remission induction. However, effective 
drugs in the induction therapy are not always efficacious in the maintenance therapy. The 
randomized, double-blinded, placebo-controlled study with an induction phase and maintenance 
phase was designed to objectively evaluate efficacy and safety both in the induction therapy and 
maintenance therapy. Additionally, the enrichment design was employed to evaluate efficacy and 
safety in the maintenance phase, in which only responders to MLN0002 in the induction phase will 
be enrolled in the population to be randomized in the maintenance phase. 
In the induction phase, in addition to the Cohort 1 for randomized, double-blinded, 
placebo-controlled, parallel-group comparison, the Cohort 2 to receive unblinded dose of 
MLN0002 was set so that the sample size in the maintenance phase was secured. 
For preservation of blindness, all responders at Week 10 will be enrolled into the maintenance 
phase irrespective of the drugs allocated in the induction phase. The responders who received 
MLN0002 in the induction phase will be randomized either to the placebo group or the MLN0002 
group for evaluation of efficacy and safety of the maintenance therapy, and the responders who 
received the placebo in the induction phase will be continued to be allocated to the placebo groups. 
In the ethically-established open-label cohort, it was designed that non-responders in the induction 
phase, patients who experienced disease worsening or received rescue treatments during the 
maintenance phase, or those completed Week 60 of the maintenance phase may continue to 
receive MLN0002 for 46 weeks (minimum) to 94 weeks (maximum). 
See Section 13.3 for justification of the sample size. 
6.2.3 
Justification of the Placebo Group 
Any active comparator is impossible to be used properly in the study in moderate to severe UC 
patients who had failed with existing pharmacotherapy (either of 
corticosteroids/immunomodulators/anti-TNFα antibodies). The placebo was selected as a 
comparator for objective evaluation of efficacy and safety. 
6.2.4 
Justification of the Dosage and the Evaluation Period 
In the Phase 3 study outside Japan in UC patients (C13006) dosed 300 mg of MLN0002 at 
Weeks 0, 2, 6 and subsequently every 8 weeks or 4 weeks, similar efficacy was observed in either 

MLN0002 
 
Study No. MLN0002/CCT-101

CONFIDENTIAL 
dosage with no safety issues[8]. The serum MLN0002 concentration was similar inside/outside 
Japan, and saturation of α4β7 receptors was observed mostly continuously from the first dose. From 
the above, the dosage in the study was selected as 300 mg of MLN0002 to be dosed at Weeks 0, 2, 
6 and subsequently every 8 weeks in a similar manner as that in C13006 study. 
Furthermore, efficacy was anticipated to be improved in association with extension of the period 
of the induction therapy based on the result from C13006. Therefore, the primary efficacy 
endpoint in the induction phase will be evaluated at Week 10. The maintenance phase is decided to 
be started from Week 14, and the primary efficacy endpoint in the maintenance phase will be 
evaluated at 46 weeks after enrollment into the maintenance phase (Week 60) in the similar 
manner as that in C13006 study. 
Meanwhile, non-responders at Week 10 may be enrolled into the open-label cohort for 
re-induction of the drug and the maintenance therapy, and receive 300 mg of MLN0002 at 
Weeks 0x, 2x, 6x and subsequently every 8 weeks for 46 weeks (minimum) to 94 weeks 
(maximum). Subjects who experienced disease worsening or received rescue treatments during the 
maintenance phase, or those who completed Week 60 of the maintenance phase can be enrolled 
into the open-label cohort to receive the study drug in the same manner. As safety was 
demonstrated in the C13006 study when MLN0002 was dosed at Weeks 0, 2 and subsequently 
every 4 weeks, enrollment into the open-label cohort was judged to impose no safety issues. 
The elimination half-life of MLN0002 was 15 to 22 days at the dose of 2 to 10 mg/kg[5]. 
Additionally, saturation of α4β7 receptors was durable at the dose of 300 mg for 16 weeks after the 
last dose, and decreased subsequently over time. The end-of-study examination for safety 
evaluation after the last dose will be conducted in a similar manner as that in studies outside Japan 
in all subjects who received the study drugs at 16 weeks after the last dose that is almost ≥5-times 
longer period than the elimination half-life and by which saturation of α4β7 receptors may be 
durable. 
PML has been reported in subjects who received natalizumab, an α4 integrin antagonist[12]. 
MLN0002 is considered unlikely to increase PML risk since it specifically binds to the intestine 
tropism α4β7 integrin, and no PML was observed in clinical trials inside/outside Japan so far. 
However, the number of subjects who received MLN0002 was not large because of the clinical 
trial stage, and the potential PML risk is difficult to be ruled out. Therefore, the follow-up survey 
will be performed every 6 months up to 2 years after the last dose of the study drug for evaluation 
of potential PML risk of the drug. 
6.2.5 
Justification of Endpoints 
The Mayo score was used as the disease activity index for UC in C13006 study[8]. The Mayo 
score, extensively used efficacy index for evaluation of UC inside/outside Japan, was selected as 
the evaluation index in the study. The clinical response and clinical remission based on the Mayo 
score were defined in the same manner as those in C13006.

the open-label cohort. For the subjects who received any rescue treatments in the open-label cohort, 
withdrawal should be considered (see Section 7.5). 
7.3.2 
Dose Reduction Schedule of Corticosteroids 
Dosage of a corticosteroid, if used concurrently, should not be modified until Week 10 after the 
first dose of the study drug in principle. When the clinical response (see Section 3.1 for the 
definition) was achieved at Week 10 or later, the dose reduction of the corticosteroid will be 
initiated as per the following schedule from the visit when the clinical response was observed, 
where possible. 
Dose Reduction Schedule: 
• When >10 mg/day was dosed, the dosage will be gradually reduced by 5 to 10 mg/2 weeks to 
reach 10 mg/day 
• When ≤10 mg/day was dosed or achieved by gradual reduction, the dosage will be gradually 
reduced by 2.5 to 5 mg/2 weeks to achieve corticosteroid-free 
When dose reduction is required earlier than Week 10 due to adverse reactions of the 
corticosteroid, only small doses of not more than 5 mg/2 weeks should be gradually reduced. 
When any symptoms recur with the dose reduction of the corticosteroid, the dosage may be 
increased up to the initial dose (it will not apply to rescue treatments). Subsequently, when clinical 
response was observed again, the dose reduction will be initiated preferably as per the above 
schedule from the visit when the clinical response was observed. 
Of note, higher dosage than the initial dosage, if used for recurrence, will be considered as a rescue 
treatment (see Section 7.3.1 for rescue treatments). 
7.4 
Subject Management 
1. Subjects should be instructed to be sure to see the physician and take specified examinations at 
the specified date and time. In addition, subjects should be instructed to inform the 
investigator or the sponsor immediately in the case that they cannot visit. 
2. Subjects should be instructed to make entries in the subject’s diary throughout the period from 
the time of signing on the informed consent form to the last dose of the study drug and to bring 
the diary with them at each visit. 
3. Subjects should be instructed to preferably visit under fasted condition at visits for blood 
biochemistry test. 
4. Subjects should be instructed to report any worsening of symptoms that occurred at any time 
other than visits, if any, to the investigator or the sponsor via telephone or the like to seek 
instructions.

5. Subjects should be instructed to report details, onset date, intensity, outcome and outcome 
date of subjective symptoms/objective findings to the investigator during their visit. 
6. Subjects should be instructed to report course and details of the treatment to the investigator if 
they visited other medical institutions during the period from the time of signing on the 
informed consent form to 16 weeks after the last dose of the study drug. 
7. Subjects should be instructed to inform a physician in a medical institution of his/her 
participation in the study, if he/she visited other medical institutions during the period from 
the time of signing on the informed consent form to 16 weeks after the last dose of the study 
drug. 
8. Subjects should be instructed not to use any drugs including OTCs other than drugs instructed 
by the investigator without prior consultation (except urgent cases). 
9. Male subjects without a sterilization history and whose female partner has child-bearing 
potential should be instructed to take proper contraception during the period from the time of 
signing on the informed consent form to 6 months after the last dose of the study drugs. 
10. Female subjects with child-bearing potential whose male partner has no sterilization history 
should be instructed to take proper contraception during the period from the time of signing on 
the informed consent form to 6 months after the last dose of the study drugs. 
11. Subjects should be instructed to avoid surfeit, extreme changes in diet, excessive 
exercise/action throughout the period from the time of signing on the informed consent form 
to the last dose of the study drug. Subjects should be instructed in an especially careful manner 
because treatment-emergent change of symptoms may lead to changes in diet. 
12. Subjects should be instructed not to donate their blood during the period from the time of 
signing on the informed consent form to 6 months after the last dose of the study drug. 
13. Subjects should be instructed to report any feelings of infusion reaction (e.g., rash, pruritus, 
flushing or urticaria) to the investigator immediately. 
7.5 
Criteria for Discontinuation or Withdrawal of a Subject 
The primary reason for discontinuation or withdrawal of a subject from the study should be 
recorded in the case report form ([e]CRF) using the following categories. See Section 9.1.22 for 
subjects who withdrew during the screening phase. 
1. Pretreatment Events or AEs 
The subject has experienced a PTE or AE that requires early termination because continued 
participation imposes an unacceptable risk to the subject’s health or the subject is unwilling to 
continue because of the PTE or AE. 
 
Liver Function Test Abnormalities 
Discontinuation of the study drug should be considered with appropriate clinical 
follow-up (including repeat laboratory tests, until a subject’s laboratory profile has

returned to normal/baseline status, see Section 9.1.12), if the following circumstances 
occur at any time during study drug treatment: 
– ALT or AST >8×ULN, or 
– ALT or AST >5×ULN and persists for more than 2 weeks, or 
– ALT or AST >3×ULN in conjunction with elevated total bilirubin >2×ULN or 
international normalized ratio (INR) >1.5, or 
– ALT or AST >3×ULN with appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash and/or eosinophilia. 
2. Major protocol deviation 
The discovery post-randomization in the induction phase that the subject failed to meet 
protocol inclusion criteria or did not adhere to protocol requirements, and continued 
participation poses an unacceptable risk to the subject’s health. 
Note: The visit for evaluation of the primary efficacy endpoint in the induction phase (Visit 5), 
when notably deviated beyond the acceptable window (≥±15 days), should be considered as a 
major protocol deviation. 
3. Lost to follow-up 
The subject did not return to the clinic and attempts to contact the subject were unsuccessful. 
Attempts to contact the subject must be documented. 
4. Voluntary withdrawal. 
The subject wishes to withdraw from the study. The reason for withdrawal, if provided, should 
be recorded in the (e)CRF. 
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (i.e., withdrawal due to an 
AE or lack of efficacy should not be recorded in the “voluntary withdrawal” category). 
5. Study termination 
The sponsor, the IRB or regulatory authorities decided to terminate the study. 
6. Pregnancy 
The subject is found to be pregnant. 
Note: If the subject is found to be pregnant, the subject must be withdrawn immediately. The 
procedure is described in Section 9.1.14. 
7. Lack of efficacy 
The investigator has determined that the subject is not benefiting from investigational 
treatment; and, continued participation would pose an unacceptable risk to the subject. 
Note: A subject who received any rescue treatments due to lack of efficacy in the induction 
phase should withdraw from the study immediately. For a subject who received any rescue

Note: The specific reasons should be recorded in the “specify” field of the (e)CRF. 
7.6 
Procedures for Discontinuation or Withdrawal of a Subject 
The investigator may terminate a subject’s study participation at any time during the study when 
the subject meets the study termination criteria described in Section 7.5. In addition, a subject may 
discontinue his or her participation without giving a reason at any time during the study. Should a 
subject’s participation be discontinued, the primary criterion for termination must be recorded. In 
addition, efforts should be made to perform all procedures scheduled for the early termination 
visit.

Procedures for Allocation, Prescription and Infusion of Study Drugs 
A study drug number will not be identical at each time. For allocation of subjects to study drugs, 
Investigators or his/her designee will access the website of the registration center at each visit for 
infusion to obtain a study drug number from the registration center. Investigators or his/her 
designee will prescribe the study based on the obtained study drug number. The study drug number 
should be recorded in (e)CRF at each administration visit. 
Details for using the website of the registration center will be in accordance with the separately 
specified written procedures. 
8.3 
Preparation and Retention of the Allocation Table 
A person in charge of allocation (appointed by the sponsor) will prepare the allocation table. 
Information of allocation should be kept in a secure place with limited access by unauthorized 
people. 
8.4 
Preservation of Blindness 
The emergency key will be kept in the emergency key control center until emergent key-breaking 
or completion of database lock of all subjects. 
In the study, allocations must not be disclosed to any person until opening of the study drug 
allocation table, while the study drug preparators may be aware of allocations in the course of 
study drug preparation. 
Furthermore, test results of serum drug concentration and HAHA/neutralizing antibody may be an 
obstacle in preservation of blindness in the study, therefore these final test results should be kept 
undisclosed outside in the test laboratory until opening of the study drug allocation table, and will 
be reported to the investigator through the sponsor upon opening. However, if a test result must be 
disclosed before opening, the test result may be reported to the sponsor or the like after necessary 
actions taken to preserve blindness (e.g., renumbering of study drugs), so that persons in charge in 
the test laboratory would be unable to identify subjects. Detailed procedures should be in 
accordance with the separately specified written procedure. 
8.5 
Procedures for Blind-Breaking 
The study drug blind will not be broken by the investigator unless information concerning the 
study drug is necessary for the medical treatment of the subject. 
In blind-breaking, the investigator may obtain study drug allocation information from the 
emergency key control center (see the Annex for contacts). 
In blind-breaking, the investigator will enter the date/time and rationale of the blind-breaking on 
the record of emergency key opening to be submitted to the sponsor. The same information (except 
time) will be recorded on (e)CRF.

Control and Disposal of Sponsor-Supplied Drugs 
The Study Drug Administrator will receive the written procedure prepared by the sponsor relating 
to handling, storing and controlling study drugs to properly control sponsor-supplied study drugs 
and materials in accordance with the written procedure. Similarly, the investigator will receive the 
same written procedures from the sponsor. The written procedure describes procedures to ensure 
proper receipt, handling, storing, controlling and prescription of the sponsor-provided study drugs 
and materials, as well as return of unused study drugs and materials to the sponsor or other 
disposition. 
The Study Drug Administrator will return unused study drugs and materials to the sponsor 
immediately after study completion in the study site.

Documentation of Concomitant Medications and Non-drug Therapy 
Concomitant medication is any drug given in addition to the study medication. These may be 
prescribed by a physician or obtained by the subject over the counter. Concomitant medication is 
not provided by Takeda. At each study visit, subjects will be asked whether they have taken any 
drug other than the study drug (used from the time of signing on the informed consent form 
through the end-of-study examination), and all drugs including vitamin supplements, OTC drugs, 
and oral herbal preparations, must be recorded in the (e)CRF. In addition, for concomitant drugs 
for UC treatment, class of the concomitant drug (5-ASA, corticosteroids, immunomodulators, or 
others), and applicability to a rescue treatment will be recorded in the (e)CRF. 
Concomitant treatments are defined as any treatments for UC other than pharmacotherapy, 
including enterectomy and other surgical treatments (e.g., abscess drainage or the seton method for 
the anal lesion). All concomitant treatments that were conducted during the period from 
acquisition of the informed consent until the end-of-study examination will be obtained. 
Additionally, applicability of the concomitant treatment to a rescue treatment will be recorded in 
the (e)CRF. 
Of note, agents applied for test procedures including endoscopy will not be considered as 
concomitant drugs and will also not be documented in the (e)CRF. 
9.1.7 
Documentation of Concurrent Medical Conditions 
Concurrent medical conditions are those significant ongoing conditions or diseases that are present 
at the time of signing on the informed consent form. This includes clinically significant laboratory, 
ECG, or physical examination abnormalities noted at screening/baseline examination. The 
condition (i.e., diagnosis) should be described. In addition, UC-related extra-intestinal 
manifestations will be recorded in the (e)CRF.

The Patient Diary 
The patient diaries are used for calculation of the Mayo scores. At each visit, patient diaries to be 
entered from the visit to the next visit will be handed to subjects. A subject will be instructed to 
record the following items in the diary and bring it at the next visit. 
• Stool frequency 
• Rectal Bleeding 
• Use of antidiarrheal drugs 
Contents of the patient diaries will be confirmed at each visit. The subject will be asked about 
omissions or inconsistencies for correction, if any. The patient diaries will be collected to be 
retained after final confirmation of the contents.

Complete Mayo Score and Partial Mayo Score 
The complete Mayo scores will be calculated as total scores of the following 4 subscores in the 
Table 9.a. The partial Mayo score will be calculated as total scores of the following 3 subscores 
except the subscore for the findings on endoscopy. 
Table 9.a

2: 3 to 4 stools more than normal 
3: 5 or more stools more than normal 
Rectal Bleeding 
0: No blood seen 
1: Streaks of blood with stool less than half the time 
2: Obvious blood with stool most of the time 
3: Blood alone passes 
Findings on Endoscopy 
0: Normal or inactive disease 
1: Mild disease (erythema, decreased vascular pattern, mild friability) 
2: Moderate disease (marked erythema, lack of vascular pattern, friability, erosions) 
3: Severe disease (spontaneous bleeding, ulceration) 
Physician's Global Assessment 
0: Normal 
1: Mild disease 
2: Moderate disease 
3: Severe disease 
 
At screening test (Visit 1), the investigator will interview about the average number of stools, 
condition of rectal bleeding and general condition during the previous 3 days, and evaluate each 
subscore based on the outcome of the interview to calculate the partial Mayo score. Each subscore 
for stool frequency, rectal bleeding and physician's global assessment will be entered on the 
website of the registration center to calculate the partial Mayo score. 
Since the first dose of the study drug (Visit 2), data in the patient diary, the subscores for the 
findings on endoscopy and physician's global assessment will be entered on the website of the 
registration center to calculate the complete Mayo score or the partial Mayo score. The 
methodology for calculating each subscore is shown below.

Calculation of Subscores for Stool Frequency and Rectal Bleeding 
For calculation of subscores for stool frequency and rectal bleeding, the contents in the patient 
diary during the previous 7 days before evaluation will be entered on the website of the registration 
center. Each subscore will be calculated automatically based on the contents in the patient diary 
during the last 3 days before evaluation except for the following. 
• The day of pretreatment for endoscopy 
• The day of endoscopy and the next day 
• The day of usage of antidiarrheal drugs and the next day 
Of note, for baseline evaluation (Visit 2), the contents of the patient diary during at least 3 days 
except for the above exception days should be entered on the website of the registration center for 
calculation of the complete Mayo score. The visit schedule will be adjusted to have the necessary 
number of days in the patient diary. 
9.1.9.2 
Calculation of the Subscore for Findings on Endoscopy 
Endoscopy will be performed in the rectum and sigmoid colon between 9 days and on the day of 
evaluation of the complete Mayo score. The investigator will identify the most active site at 
baseline, and score the identical site for the findings on endoscopy throughout the study period 
based on Table 9.a. The findings on endoscopy will be scored by the same physician throughout 
the study, where possible. The obtained subscore for findings on endoscopy will be entered on the 
website of the registration center. 
Additionally, the Clinical Endpoint Committee (CEC; see Section 11.2) will be established in the 
study, where subscores for findings on endoscopy will be assessed independently. Therefore, 
investigator should submit clear images to the Sponsor, by which the CEC may assess the subscore 
for findings on endoscopy. 
Of note, the result of endoscopy performed within 9 days before evaluation (before acquisition of 
the informed consent) may be used for the base line assessment (Visit 2), if available, in the 
invasiveness point of view. 
9.1.9.3 
Calculation of Physician's Global Assessment 
On the evaluation day, investigator will interview about abdominal discomfort, general condition, 
principal physician’s comments, subject’s impression or the like to decide the Physician's Global 
Assessment as referring the result of the interview, stool frequency and rectal bleeding and 
findings on endoscopy (if performed).

Note 1) The samples should be preferably collected under fasted conditions. 
Note 2) The test results of the serum immunological tests should be reported to subjects directly by investigator, and 
not be provided to the sponsor. 
 
The above laboratory test items will be determined at the laboratory site for the study except urine 
pregnancy tests. The urine pregnancy tests will be performed at the study sites. Investigator will 
assess and retain the clinical laboratory test results reported. 
If subjects experience ALT or AST >3×ULN, follow-up laboratory tests (at a minimum, ALP, 
ALT, AST, total bilirubin, γ-GTP, and INR) should be performed preferably within 48 to 72 hours 
or within 7 days at the latest after the blood sampling (see Section 7.5 and Section 10.2.3). 
If the ALT or AST remains elevated >3×ULN on these 2 consecutive occasions, the investigator 
must contact the Medical Monitor for consideration of additional testing, close monitoring, 
possible discontinuation of the study drug, discussion of the relevant subject details and possible 
alternative etiologies. 
Investigators will retain references of the clinical laboratory tests and their tracking. 
9.1.13 
Contraception and Pregnancy Avoidance Procedure 
During the period from the time of signing on the informed consent form to 6 months after the last 
dose of the study drug, female subjects of childbearing potential (who have no history of 
sterilization or have menstruation within previous 2 years) must use proper contraception. In 
addition, during the period from the time of signing on the informed consent form to 6 month after 
the last dose of the study drug, male subjects without history of sterilization and whose female 
partner has child bearing potential must prevent pregnancy. Such subjects will be provided with 
information on acceptable methods of contraception as part of the subject informed consent 
process, and will be asked to sign a consent form stating that they understand the requirements for 
avoidance of pregnancy during the course of the study. During the course of the study, the 
specified urine pregnancy tests will be performed, and subjects will receive continued guidance 
with respect to avoiding pregnancy. 
Urine pregnancy tests performed at screening and at immediately before the first dose of the study 
drug should be confirmed to show negative. 
In addition, male subject must be advised not to donate sperm from the time of signing on the 
informed consent form to 6 months after the last dose of the study drug. 
9.1.14 
Pregnancy 
If any subject is found to be pregnant during the study, she should be withdrawn and any 
sponsor-supplied study drugs should be immediately discontinued. 
Any pregnancies occurred during the period from the first dose of the study drug (Visit 2) to 6 
months after the last dose of the study drug should be reported, using the given report form, to the 
contact listed in the Annex. In addition, any pregnancies in the partner of a male subject during the

period from the first dose of the study drug (Visit 2) to 6 months after the last dose of the study 
drug should also be recorded following authorization from the subject’s partner. 
Should the pregnancy occur during or after administration of the blinded drug, the investigator 
must inform the subject of their right to receive treatment information. Upon subject’s request, the 
investigator will open the Emergency Key. Subjects revealed not to have received MLN0002 in 
the study are not required to be followed. 
Upon consent with the female subject or the female partner of the male subject, the investigator 
should inform their physician (an obstetrician) that the subject/female partner of the subject was 
participating in the clinical study at the time of conception with details of treatment the subject 
received (blinded or unblinded, as applicable). 
All reported pregnancies will be followed up to final outcome, using the pregnancy form. The 
outcome, including any premature termination, must be reported to the sponsor. An evaluation 
after the birth of the child will also be conducted. 
9.1.15 
ECG Procedure 
A standard 12-lead ECG will be recorded. The investigator (or a qualified observer at the study 
site) will interpret the ECG using 1 of the following categories: within normal limits, abnormal but 
not clinically significant, or abnormal and clinically significant. 
9.1.16 
PML Evaluation 
PML will be evaluated based on the PML checklists (Appendix D), which will be performed 
before administration of the study drug if it is the day of study drug administration. 
At first, the subjective symptoms will be checked by use of the Subjective PML checklist. When 
any subjective symptoms are recognized, the corresponding objective findings will be checked by 
use of the Objective PML checklist. When any abnormalities are found in the objective findings as 
well, the subject will be evaluated in accordance with the algorithm for subject evaluation in the 
PML checklists. 
The evaluation result based on the PML checklists will be recorded in the (e)CRF. Any subjective 
symptoms or objective findings found in the PML checklists will be collected as AEs as well. 
9.1.17 
Tuberculosis test 
As a sample for tuberculosis test, 7 mL of the whole blood will be collected. The laboratory site for 
the study will collect the sample to conduct tuberculosis test by means of T-SPOT. The 
tuberculosis test using QuantiFERON may be conducted, when routinely employed in the study 
site. The test results, i.e. positive, negative, indeterminate or indeterminable, will be recorded in 
the (e)CRF.

Chest Imaging Procedure 
Existence of findings of tuberculosis will be confirmed by the chest X-ray or chest CT. The 
imaging performed within 3 months before evaluation as a part of general practice not as a test for 
the study may be used, if available. Date of Examination and existence of findings of tuberculosis 
will be recorded in the (e)CRF. 
Of note, the imaging obtained before acquisition of the informed consent may be used at screening. 
9.1.19 
Pharmacogenomic Sample Collection 
For exploratory research to identify a predictable marker of drug response, 5 mL of the whole 
blood will be once collected as a pharmacogenomic sample from subjects entered into the 
induction phase and who agreed with the pharmacogenomic research at the earliest possible time 
during the period from Visit 2 to the end of the study. 
However, the pharmacogenomic samples will not be collected from subjects with a history of an 
allogeneic bone marrow transplantation. 
See the separately specified written procedure for collecting, handling, and storing the 
pharmacogenomic samples. 
9.1.20 
Pharmacokinetic Sample Collection and Analysis 
Pharmacokinetic samples will be collected only in study sites with a cooled centrifuge. In these 
study sites, 3 mL of the venous blood will be collected for determination of serum MLN0002 
concentration. At the visit for study drug administration, the blood should be sampled immediately 
before administration, where possible. The date and time of the blood sampling will be recorded in 
the (e)CRF. 
The collected blood will be left standing at room temperature for approximately 30 minutes and 
centrifuged at 3,000 rpm at 4°C for 10 minutes. The obtained serum will be cryopreserved in a 
preset freezer at a temperature of ≤-20°C until collection. The samples will be handled in 
accordance with the separately specified procedures. 
Serum MLN0002 concentration will be determined in 
 by means of 
Enzyme-Linked ImmunoSorbent Assay (ELISA). However, samples of subject who have not 
received MLN0002 throughout the induction and maintenance phases will not be determined. 
9.1.21 
Sample Collection for the HAHA/Neutralizing Antibody Test 
Samples for the HAHA/neutralizing antibody test will be collected only in study sites with a 
cooled centrifuge. In these study sites, 5 mL of the venous blood will be collected for the 
HAHA/neutralizing antibody test. At the visit for study drug administration, the blood should be 
sampled immediately before administration, where possible. The date and time of the blood 
sampling will be recorded in the (e)CRF.

Of note, even though the above linkage may be possible, when Pharmacogenomic Research has 
been conducted already, the sponsor may keep the anonymized results of the Pharmacogenomic 
Research with the residual samples disposed. 
The sponsor will create a necessary written procedure as establishing a necessary control system 
for protecting subjects’ personal information and predefining the standards for collection, 
retention and disposal of samples.

Follow-Up Survey 
In the study, the follow-up survey will be conducted via telephone, etc., by using the follow-up 
survey form (Appendix E) every 6 months up to 2 years (maximum) after the last dose of the study 
drug or until the marketing approval date of the drug, whichever comes earlier, for any subjects 
who received the study drug (including subjects who withdrew). The follow-up survey include the 
following items. Of note, the follow-up survey forms will be collected by the sponsor.

PRETREATMENT EVENTS AND ADVERSE EVENTS 
10.1 
Definitions 
10.1.1 
PTEs 
A PTE is defined as any untoward medical occurrence in a subject who has signed the informed 
consent to participate in a study but prior to administration of any study drug; it does not 
necessarily have to have a causal relationship with study participation. 
10.1.2 
AEs 
An AE is defined as any untoward medical occurrence in a study subject who received a drug 
(including a study drug); it does not necessarily have to have a causal relationship with this 
treatment. 
An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug 
whether or not it is considered related to the drug. 
10.1.3 
Additional Points to Consider for PTEs and AEs 
An untoward finding generally may include: 
• A new diagnosis or those representing unexpected worsening of a pre-existing condition 
(intermittent events of pre-existing conditions of an underlying disease should not be 
considered PTEs or AEs.) 
Intermittent events of pre-existing conditions of an underlying disease in the study include 
some UC-specific symptoms such as diarrhea or abdominal pain. These symptoms, which may 
be sustained or varied in the course of the study depending on medical histories of each subject, 
will be considered as medically-predictable clinical symptoms in the disease addressed in the 
study, and therefore, not be subjected for collection of AEs. These symptoms corresponding to 
disease activity will be assessed as a part of the Mayo score. However, worsening of disease 
activity (e.g., abdominal pain aggravated beyond a normal range, or newly-observed 
symptoms or findings) will be collected as AEs. Onset or worsening of extra-intestinal 
manifestations in the course of the study will be collected as AEs. 
• Those requiring therapeutic intervention 
• Those requiring an invasive diagnostic procedure 
• Those requiring discontinuation or dose modification of the study drug or a concomitant drug 
• Those considered as unfavorable by the investigator for any reason. 
Diagnoses vs signs and symptoms: 
PTEs and AEs (hereinafter called as PTEs/AEs) will be described as diagnoses. Accompanying 
signs (including abnormal laboratory values or ECG findings) or symptoms should NOT be 

MLN0002 
 
Study No. MLN0002/CCT-101

Initial Protocol 
November 11, 2013 
 
CONFIDENTIAL 
recorded as PTEs/AEs. If a diagnosis is unknown, sign(s) or symptom(s) should be recorded 
appropriately as PTEs/AEs. 
Laboratory values and ECG parameters: 
Changes in laboratory values or ECG parameters are considered as PTEs/AEs only when they are 
judged to be clinically significant (i.e., when some action or intervention is required or if 
investigator judges the change as being beyond the range of normal physiologic fluctuation). A 
laboratory re-test and/or continued monitoring of an abnormal value are not considered an 
intervention. In addition, repeated or additional noninvasive testing for verification, evaluation or 
monitoring of an abnormality is not considered an intervention. 
If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (e.g., increased creatinine in renal failure), the diagnosis only should be reported 
appropriately as a PTE or as an AE. 
Pre-existing conditions: 
Any pre-existing diseases or conditions prior to acquisition of the informed consent will be 
recorded as complications not as PTEs/AEs. Baseline evaluations (e.g., laboratory tests, ECG, 
X-rays etc.) should NOT be recorded as PTEs unless related to study procedures. However, 
abnormal findings caused by the baseline evaluation (e.g., internal hemorrhage at blood sampling) 
are recorded as PTEs to be entered in the (e)CRF. Investigators should ensure that the event term 
recorded captures the change in the condition (e.g., “worsening of…”). 
If a subject has a pre-existing episodic condition (e.g., asthma, epilepsy), any occurrence of an 
episode should be captured as a PTE/AE only when the episodes become more frequent, serious or 
severe in nature, that is, investigators should ensure that the AE term recorded captures the change 
in the condition from Baseline (e.g., “worsening of…”). If a subject has a degenerative concurrent 
condition (e.g., cataracts, rheumatoid arthritis), worsening of the condition should be captured as a 
PTE/AE only when occurring to a greater extent to that which would be expected. Again, 
investigators should ensure that the AE term recorded captures the change in the condition (e.g., 
“worsening of…”). 
Worsening of PTEs/AEs: 
If the subject experiences a worsening or complication of a PTE after starting administration of the 
study drug, the worsening or complication should be recorded appropriately as an AE. 
Investigators should ensure that the AE term recorded captures the change in the condition (e.g., 
“worsening of…”). 
If the subject experiences a worsening or complication of an AE after any change in the study drug, 
the worsening or complication should be recorded as a new AE. Investigators should ensure that 
the AE term recorded captures the change in the condition (e.g., “worsening of…”). 
Changes in severity of AEs/Serious PTEs: 
If the subject experiences changes in severity of an AE/serious PTE, the event should be captured 
once with the maximum severity recorded.

CONFIDENTIAL 
Preplanned surgeries or procedures: 
Preplanned procedures (surgeries or therapies) that were scheduled prior to the time of signing on 
the informed consent form are not considered PTEs/AEs. However, if a preplanned procedure is 
performed early (e.g., as an emergency) due to a worsening of the pre-existing condition, the 
worsening of the condition should be captured appropriately as a PTE/AE. Complications 
resulting from any planned surgery should be reported as AEs. 
Elective surgeries or procedures: 
Elective procedures performed where there is no change in the subject’s medical condition should 
not be recorded as PTEs/AEs, but should be documented in the subject’s source documents. 
Complications resulting from an elective surgery should be reported as AEs. 
Insufficient clinical response (lack of efficacy): 
Insufficient clinical response, efficacy, or pharmacologic action should NOT be recorded as an AE. 
Investigator must make the distinction between exacerbation of pre-existing illness and lack of 
therapeutic efficacy. 
Overdose: 
Cases of overdose with any drug are NOT considered AEs, but instead will be documented on an 
Overdose page of the (e)CRF. Any manifested side effects at overdose will be considered AEs and 
will be recorded on the AE page of the (e)CRF. 
10.1.4 
SAEs 
SAEs are defined as the following out of any untoward medical occurrence in a study subject who 
received a drug (regardless of dosages); 
1. Results in DEATH. 
2. Is LIFE THREATENING* 
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization. 
4. Results in persistent or significant DISABILITY/INCAPACITY. 
5. Leads to a CONGENITAL ANOMALY/BIRTH DEFECT. 
6. Other medically significant conditions  
May require intervention to prevent the above items 1 through 5, or may expose the subject to 
danger, even though the event is not immediately life-threatening or fatal or does not result in 
hospitalization. That includes any events or synonyms described in the Takeda Medically 
Significant AE List (Table 10.a). 
*The “life-threatening” here represents that life of the subject was threatened by onset of the event, 
and does not represent hypothetically that a more sever event might cause death.

10.1.5 
Intensity of PTEs and AEs 
Intensity of PTEs/AEs will be classified/defined as per the following. 
Mild: 
The event is transient and easily tolerated by the subject. 
Moderate: 
The event causes the subject discomfort and interrupts the subject’s usual activities. 
Severe: 
The event causes considerable interference with the subject’s usual activities. 
10.1.6 
Causality of AEs 
Causal relationship between AEs and study drugs will be classified/defined as per the following. 
Related: 
An AE that follows a temporal sequence from administration of a drug (including the course after 
withdrawal of the drug), or for which possible involvement of the drug can be argued, although 
factors other than the drug, such as underlying diseases, complications, concomitant drugs, and 
concurrent treatments, may also be responsible. 
Not Related: 
An AE that does not follow a temporal sequence from administration of a drug and/or that can 
reasonably be explained by other factors, such as underlying diseases, complications, concomitant 
drugs, and concurrent treatments. 
10.1.7 
Relationship to Study Procedures 
Relationship (causality) to study procedures should be determined for all PTEs/AEs. The 
relationship should be assessed as Yes if the investigator considers that there is reasonable 
possibility that an event is due to a study procedure. Otherwise, the relationship should be assessed 
as Not Related.

Procedures 
10.2.1 
Collection and Reporting of AEs 
10.2.1.1 
PTE and AE Collection Period 
PTEs will be continuously collected during the period from acquisition of the informed consent to 
the first dose of the study drug (Visit 2), or until withdrawal when decided before the first dose of 
the study drug.

CONFIDENTIAL 
AEs will be continuously collected during the period from the first dose of the study drug (Visit 2) 
to the end-of-study examination at 16 weeks after the last dose of the study drug. 
10.2.1.2 
PTE and AE Reporting 
Subjects may report PTEs/AEs occurring at any other time during the study. PTEs/AEs not 
emerging at visit will be obtained from subjects with questions such as “How was your condition 
after the last visit?.” 
Investigators will follow all subjects who developed a serious PTE until recovery/resolution of the 
event or recovery of the clinically relevant abnormal test value to the baseline value after 
acquisition of the informed consent, or otherwise (for persistent/irreversible PTEs) until 
establishment of sufficient rationale for the observed change. Subjects who developed not-serious 
PTEs are not required to be followed irrespective of relationship with study procedures in the 
protocol. 
Investigators will follow all subjects who developed an AE (with or without relationship with the 
study drug) until recovery/resolution of the event or recovery of the clinically relevant abnormal 
test value to the value before the first dose of the study drug, or otherwise (for 
persistent/irreversible AEs) until establishment of sufficient rationale for the observed change. All 
PTEs/AEs should be recorded in the (e)CRF. For a PTE/AE, the name, onset date, 
recovery/resolution date, start period, frequency, severity, causal relationship with the study drug 
(related/not-related), disposition of the study drug, outcome, causal relationship with the study 
procedures (if related, the possible causal procedure), and seriousness will be recorded. 
For AEs that occurred during infusion of the study drug or the period from initiation to 1 hour after 
completion of infusion, onset time and association with infusion will be recorded in the (e)CRF. 
AEs/serious PTEs will be followed until the PTE/AE is recovered/resolved or the investigator 
judges not to follow them any longer. 
10.2.2 
Collection and Reporting of SAEs 
When a SAE occurs during the AE collection period, it should be reported according to the 
following procedure: PTEs that fulfill 1 or more of the serious criteria described in Section 10.1.4 
are also considered as SAEs to be reported and followed in the same manner. 
Investigators should report the SAE within 1 working day after onset of the SAE or receipt of the 
notice of the event onset from a subject, etc., to the sponsor (see the Annex for contacts). 
Additionally, the investigator should submit the detailed formal reports within 10 calendar days. 
Of note, the following is specified as the essential items to be reported within 1 working day, 
however, other items should be provided as much as possible. 
• A short description of the event and the reason why the event is categorized as serious. 
• Subject Identification Code 
• Investigator’s name.

• Name of the study drugs 
• Causality assessment 
Any SAE spontaneously reported to the investigator following the AE collection period (including 
the follow-up survey period) should be reported to the sponsor. 
10.2.3 
Drug-induced Liver Function Test Abnormal Possibly Leading to Sever Liver 
Disorder 
If a subject is noted to have ALT or AST >3 ×ULN and total bilirubin >2 ×ULN for which an 
alternative etiology has not been identified, the event should be recorded as an SAE and reported 
as per Section 10.2.2. The investigator must contact the Medical Monitor for discussion of the 
relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or B or 
other acute liver disease. Follow-up laboratory tests as described in Section 9.1.12 must also be 
performed. These abnormal liver function test values, when judged not to be explained by any 
other factors, should be reported as SAEs (see Section 10.2.2). 
10.3 
Follow-up of SAEs 
For information obtained after submission of the detailed report, the investigator should describe 
them in a copy of the submitted SAE Report Form or as an independent document in order to be 
submitted to the contact listed in the Annex. Copies of any relevant data from the hospital notes 
(e.g., ECGs, laboratory tests, discharge summary, postmortem results) should be sent to the 
addressee, if requested. 
All SAEs should be followed up until resolution or permanent outcome of the event. 
10.3.1 
SAE Reports to Investigators, the IRBs and Regulatory Authorities 
The sponsor should report any suspected unexpected serious adverse reactions (SUSARs) and 
other SAEs subjected to the expedited report to regulatory authorities, investigators and the heads 
of the study sites in accordance with the laws/regulations in the countries where the study is 
conducted. Relative to the first awareness of the event by/or further provision to the sponsor or its 
designee, SUSARs will be submitted to regulatory authorities within 7 days for fatal and 
life-threatening events and 15 days for other serious events. Similarly, the sponsor will submit 
expedited reports for other significant safety information considered to substantially affect 
benefit/risk of the study drug, or continuation of treatment or the study itself. The copies of these 
expedited report-related documents will be submitted to the IRBs in the study sites.

STATISTICAL METHODS 
13.1 
Statistical and Analytical Plans 
Since the study has different objectives in the induction phase and maintenance phases/open-label 
cohort, analyses will be conducted separately among these. 
The Statistician in the study will prepare and finalize the Statistical Analysis Plan prior to 
blind-breaking. The document will provide further details regarding the definition of analysis 
variables and analysis methodology to address all study objectives. 
The double-blinded review should be conducted prior to blind-breaking. In the double-blinded 
review, accuracy and completeness of the study data, feasibility of subject evaluation, and 
acceptability of the planned analysis methodology will be evaluated. 
The data for marketing application will be analyzed, which includes data of all subjects as fixed on 
the cut-off date for marketing application. Additionally, the open-label cohort will be analyzed 
separately at the time when the last subject completed the study. 
13.1.1 
Analysis Sets 
In the study, 3 types of analysis sets will be used in the induction phase, i.e., the “Full Analysis Set 
of the induction phase,” “Per Protocol Set of the induction phase” and “Safety Analysis Set of the 
induction phase.” 
The “Full Analysis Set of the induction phase,” a primary population for the efficacy analysis in 
the induction phase, is defined as “subjects who were randomized and received at least one dose of 
the study drug in the induction phase.” 
Three types of analysis sets will be used in the maintenance phase, i.e., the “Full Analysis Set of 
the maintenance phase,” “Per Protocol Set of the maintenance phase” and “Safety Analysis Set of 
the maintenance phase.” 
The “Full Analysis Set of the maintenance phase,” a primary population for the efficacy analysis in 
the maintenance phase, is defined as “subjects who were randomized and received at least one 
dose of the study drug in the maintenance phase.” 
Two types of analysis sets will be used in the open-label cohort, i.e., the “Full Analysis Set in the 
open-label cohort” and “Safety Analysis Set in the open-label cohort.” 
The “Safety Analysis Set in the open-label cohort” in the open-label cohort, a population for the

Determination of Sample Size 
Subjects to be randomized in the induction phase: 246 subjects 
Number of subjects to be evaluated in the induction phase (number of “subjects randomized and 
who received at least one dose of the study drug in the induction phase”) 
MLN0002 group in the induction phase: 164 subjects 
Placebo group in the induction phase: 82 subjects 
Total: 246 subjects 
Subjects to be enrolled into the maintenance phase: approximately 110 to 140 subjects 
Number of subjects to be evaluated in the maintenance phase (number of “subjects randomized 
and who received at least one dose of the study drug in the maintenance phase”) 
MLN0002 group in the maintenance phase: 42 to 55 subjects 
Placebo group in the maintenance phase: 42 to 55 subjects 
Total: 84 to 110 subjects

UC (C13006), the clinical response at Week 10 and clinical remission at Week 60 for MLN0002 
and the placebo in this study was estimated to be 57.1% and 35.5%, and 43.3% and 15.9%, 
respectively. 
When the clinical response at Week 10 in the induction phase is analyzed using Pearson's 
chi-square test with 2-sided significance level of 5%, 164 and 82 subjects (at a ratio of 2:1, total 
246 subjects) will be required respectively for the MLN0002 and placebo group to detect 
significance with a power of at least 90%. These numbers were therefore selected as numbers of 
evaluable subjects of the primary endpoint of the induction phase. When the clinical remission at 
Week 10 in the induction phase is analyzed on these numbers of subjects, statistical significances 
in both the clinical response at Week 10 and clinical remission at Week 10 are detected with a 
power of 69%. 
When the clinical remission at Week 60 in the maintenance phase is analyzed using Pearson's 
chi-square test with 2-sided significance level of 5%, 42 subjects each for the MLN0002 and 
placebo group (total 84 subjects) will be required to detect significance with a power of at least 
80%. Similarly, 55 subjects each (total 110 subjects) will be required to detect significance with a 
power of at least 90%. These numbers were therefore selected as numbers of evaluable subjects of 
the primary endpoint of the maintenance phase. Subjects enrolled into the maintenance phase 
include “those assigned to the placebo group in the induction phase” to maintain the blindness in 
the induction phase. To detect significance with a power of 80 and 90% for the analysis of the 
primary endpoint of the maintenance phase, therefore, 110 and 140 subjects will be respectively 
necessary for subjects randomized in the maintenance phase.

QUALITY CONTROL AND QUALITY ASSURANCE 
14.1 
Study-Site Monitoring Visits 
Monitoring visits to the study site will be made periodically during the study to ensure that all 
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the (e)CRFs. Source documents are defined as original documents, data, and records. 
The investigator and head of the study site should assure the sponsor (or its designee) or the IRB to 
review source documents. 
The sponsor or its designee will review records including Investigator’s files, drugs, subjects’ 
medical records and informed consents to verify that the study is being conducted properly in 
compliance with the protocol. In addition, consistency will be verified between raw data and the 
(e)CRF. It is important that the investigator and other study personnel are available during the 
monitoring visits and that sufficient time is devoted to the process. 
14.2 
Protocol Deviations 
Investigators may deviate from or modify the protocol without prior written agreement with the 
sponsor and prior approval from the IRB in medically inevitable occasions including any danger in 
subjects to be avoided urgently. After that, the investigator will give notice about details and 
reasons of the deviation or modification to the sponsor and the head of the study site in writing, 
retaining a copy, and discuss revisions of the protocol with the sponsor for agreement, if needed. If 
revision is needed, a draft of the revision will be submitted to the head of the study site at the 
earliest possible time to be approved by the IRB. 
Investigators will record all deviations from the protocol. 
14.3 
Quality Assurance Audits and Regulatory Agency Inspections 
The study site also may be subject to quality assurance audits by the sponsor or designees. In this 
circumstance, the sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the drug 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 (e.g., the FDA, the United Kingdom Medicines and Healthcare products 
Regulatory Agency). If the study site is contacted for an inspection by a regulatory body, the 
sponsor should be notified immediately. The Investigator and the head of institution guarantee 
access for quality assurance auditors to all study documents as described in Section 14.1.

ETHICAL ASPECTS OF THE STUDY 
This study will be conducted with the highest respect for the individual participants (i.e., 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. 
15.1 
IRB Approval 
IRBs will be established in accordance with local laws/regulations in the area where the study will 
be conducted. The sponsor or its designee will obtain a document describing names and titles of 
members of the IRB If any member of the IRB directly participates in this study, written 
notification regarding his or her abstinence from voting must also be obtained. 
The sponsor or designee will supply relevant documents for submission to the respective IRB for 
the protocol’s review and approval. This protocol, 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 for approval. The sponsor or its designee will obtain an approval document for the protocol 
and the informed consent form the IRB prior to the first dose of the study (i.e., before delivery of 
sponsor-supplied drugs). The IRB approval must refer to the study by exact protocol title, number, 
and version date; identify versions of other documents (e.g., informed consent form) reviewed; 
and state the approval date. The drugs will be dispatched after sponsor’s validation of regulatory 
documents in the study site. Any procedures in the screening phase described in the protocol 
should not be started until the study site receives the drugs. 
The study site should comply with all requirements specified by the IRB. This may include 
notification to the IRB 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, and submission of the Investigator’s final status report to the IRB. All IRB 
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. Subject incentives should be 
approved by the IRB and the sponsor. 
Regarding pharmacogenomic investigation using collected and stored specimens, analysis will be 
carried out at the time when detail is determined. The sponsor will create a research protocol for 
pharmacogenomics investigations and a research protocol will require prior approval of the 
company IRB in Japan. 
15.2 
Subject Information, Informed Consent, and Subject Authorization 
Written consent documents will embody the elements of informed consent as described in the 
Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance with all

applicable laws and regulations. Written consent documents describe availability and disclosure 
(to any third-parties inside/outside Japan) of subjects’ personal information and personal medical 
information in the study. The informed consent includes detailed explanation pertaining to primary 
intention, purpose, and possible risks/benefits. 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. 
Investigators have responsibility for preparation, contents and approval to be obtained from the 
IRB for the informed consent. The informed consent should be approved by the IRB prior to being 
effective. 
The informed consent should be described in understandable wording for subjects. Investigators 
must explain the contents of the informed consent thoroughly to the subjects. Information should 
be provided in a proper manner as approved by the IRB both orally or in writing, where possible. 
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. The 
subject or the subject’s legally acceptable representative, when he/she has decided to participate in 
the study, should enter the signature (or name/seal) and date on the informed consent prior to 
participation. Investigators should request the subject or the subject’s legally acceptable 
representative to enter his/her formal (not nicknames, etc.) signature or name/seal by use of a black 
or blue ballpoint pen. Investigators should enter the signature (or name/seal) and date on the 
informed consent prior to the subject’s participation in the study, as well. 
Investigators should retain originals of the informed consent with signatures or names/seals. 
Investigators should record the date of acquisition of the subject’s signature or name/seal on the 
informed consent in the subject’s medical record. Additionally, a copy of the informed consent 
with the signatures or names/seals will be provided 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. 
The Pharmacogenomic Research will be explained based on “the informed consent for the 
Pharmacogenomic Research in the study for MLN0002” to the subjects who were given an 
explanation by use of the informed consent of the study. Sampling for Pharmacogenomic Research 
will be performed in the subjects who gave both informed consents for the study and the 
pharmacogenomic investigation. 
When a subject requests disposal of his/her retained samples, it will be implemented according to 
Section 9.4.

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 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 (e.g., FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs to review the subject’s original medical records (source data or documents), 
including, but not limited to, laboratory test result reports, ECG reports, admission and discharge 
summaries for hospital admissions occurring during a subject’s study participation, and autopsy 
reports. Access to a subject’s original medical records requires the specific authorization of the 
subject as part of the informed consent process (see Section 15.2). 
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (i.e., subject name, address, and other identifier fields 
not collected on the subject’s [e]CRF).

ET=early termination, IBDQ=Inflammatory Bowel Disease Questionnaire, HAHA=human anti-human antibody, PGx=pharmacogenomics, 
PK=pharmacokinetics, PTE=pretreatment event 
a. The date of the first dose of the study drug in the induction phase is Week 0 (Day 1). The acceptable time windows are given as the number of days 
away from each scheduled visit. 
b. Will be performed before administration of the study drug on the day of study drug administration. 
c. Not required when a chest image performed within 3 months is available (the image taken before the informed consent date is acceptable at screening). 
d. Will be performed only in women of childbearing potential. 
e. Endoscopy for the assessment of total Mayo score will be performed within 9 days before day of the assessment of total Mayo score. 
f. If the study drug is administrated in the visit, blood sample should be drawn immediately before study drug administration. If the study drug is not 
administrated in the visit, blood sample can be drawn at any time at visits. All blood sampling will be conducted only in study sites with a cooled 
centrifuge. 
g. Will be collected only in subjects who have consented to participate in PGx research once at the earliest possible time between Visit 2 and study 
completion. 
h. A PTE is an event that occurred before the first dose of the study drug. An AE is an event that occurred after the first dose of the study drug. 
i. If subjects with a history of tuberculosis or those with suspicion of it start preventive isoniazid treatment before study enrollment, screening can be 
conducted between Day -28 and Day -3. Study drug administration must be conducted 21 or more days after isoniazid administration starts. 
j. Subjects who will prematurely withdraw from the study in the induction phase after receiving at least one dose should visit the clinical site and have 
examinations for discontinuation as soon as possible. 
k. Subjects who will prematurely withdraw from the study in the maintenance phase should visit the clinical site and have examinations for 
discontinuation as soon as possible. Eligible subjects will be enrolled into the open-label cohort 3 to 9 weeks after the last dose of the study drug in the 
maintenance phase. 
l. Unscheduled visit will be made due to worsening of UC, etc. Additional tests will be performed as required. 
m. Can be conducted between Day -21 and Day -1. If subjects with a history of tuberculosis or those with suspicion of it start preventive isoniazid 
treatment before study enrollment, screening can be conducted between Day -28 to Day -1. Study drug administration must be conducted 21 or more 
days after isoniazid administration starts. 
n. The test results should be obtained by Visit 2. 
o. Results of endoscopy performed within 9 days before evaluation (before the informed consent) can be used for the assessment if available. 
p. Partial Mayo score can be acceptable at discontinuation of the study. 
q. The date of the enrollment into the open-label cohort is Week 0x (Day 1x) and the study site visit on Day 1x is Visit 1x. The acceptable time windows 
are given as the number of days away from each scheduled visit. 
r. Subjects who will prematurely withdraw from the study in the open-label cohort should visit the clinical site and have examinations for discontinuation 
as soon as possible. And the same examination will be conducted in the study termination scheduled 46 weeks after the last subject will be enrolled into 
the open-label cohort. 
s. Will be performed after enrollment into the open-label cohort. 
t. Will not be performed in subjects who prematurely withdraw from the study.

Appendix C Diagnostic Criteria for UC (Revised on January 17, 2013) 
1. Definition 
A non-specific diffuse inflammation in the colon, mainly involving the mucosa and often forming 
erosion or ulcer. The name and overview specified by Council for International Organization of 
Medical Science (CIOMS) in the WHO are provided below; (1973) 
Idiopathic proctocolitis 
An idiopathic, non-specific inflammatory disorder involving primarily the mucosa and submucosa 
of the colon, especially the rectum. It appears mainly in adults under the age of 30, but may affect 
children and adults over the age of 50. Its aetiology remains unknown, but immunopathological 
mechanisms and predisposing psychological factors are believed to be involved. It usually 
produces a bloody diarrhoea and various degrees of systemic involvement, liability to malignant 
degeneration, if of long duration and affecting the entire colon. 
2. Diagnostic Procedures 
For a suspected patient of the disease as having chronic (viscous) rectal bleeding or the like, 
infectious enteritis should be firstly excluded by interview of histories including radiotherapy, 
antibiotics and traveling abroad, and by microbiological/parasitological examination. Then, the 
disease-specific intestinal lesion should be confirmed by endoscopy in the rectum and sigmoid 
colon. At the time, biopsy will be accompanied. Most patient may be diagnosed from the above, 
however other examinations including the barium enema radiography or the endoscopy in the 
entire colon may be performed, as needed, to see description, intensity and extent of involvement 
of the intestinal lesion, and also to exclude other disease. 
3. Diagnostic criteria 
A patient who meets the following a), 1 item in b) and c) may be definitively diagnosed, when the 
following diseases are ruled out. 
a) Clinical condition: continuous or repetitive (viscous) rectal bleeding or its history 
b) [1] Endoscopy: i) shows diffusely-affected, rough or finely-granular mucosa with invisible 
vascular pattern, which are also friable and bleed easily (contact bleeding) with adhesion of 
viscous sanguinopurulent-secreted matters adhered, or ii) shows multiple erosion, ulcer or 
pseudopolyposis. 
[2] The barium enema radiography: shows i) diffuse change on the rough or finely-granular 
mucosal surface, ii) multiple erosion or ulcer, and iii) pseudopolyposis. It also shows 
disappearance of colonic haustra (lead pipe appearance) or narrowing/shortening of the 
intestine. 
c) Histological biopsy: shows diffuse inflammatory infiltration, crypt abscess and severe 
decrease of goblet cells in all layers of the mucosa during the active stage. As findings are 
each non-specific, a comprehensive judgment is required. Misalignment of the gland

CONFIDENTIAL 
(tortuosity or bifurcation) and atrophy remain during the remission stage. The above changes 
are usually observed from the rectum toward the mouth sequentially  
A patient, in whom the examinations in the above b) and c) may not be performed partially or 
completely, but in whom the disease-specific findings are observed macroscopically or 
histologically in resective operation or autopsy, may be definitively diagnosed when the following 
diseases are ruled out. 
The diseases that should be ruled out include mainly infectious enteritis such as shigellosis, amebic 
colitis, salmonella enteritis, campylobacter enteritis, colonic tuberculosis and chlamydial enteritis, 
and others such as CD, radiation-induced colitis, dug-induced colitis, lymphoid 
follicle-proliferative disorder, ischemic colitis, and intestinal Behcet's syndrome. 
[Note 1] Some rare patients should be noted, who may not be aware of rectal bleeding or who 
visit immediately after awareness of rectal bleeding (shorter disease duration) 
[Note 2] A patient who may not definitively be diagnosed with mild findings should be 
“suspected” and would be diagnosed later as “definite” at recurrence, etc., showing clear 
findings. 
[Note 3] Indeterminate colitis 
A patient, who is difficult to be definitively diagnosed as showing clinical and 
pathological findings of both CD and UC, may come to show more specific findings of 
either disease in the course of follow-up. 
4. Pathology (Classification, Stages and Severities) 
A. Classification by extent of the lesion 
Total colitis 
Left-sided colitis 
Proctitis 
Right-sided or segmental colitis 
[Note 4] Left-sided colitis is not extending over the splenic flexure. 
[Note 5] Proctitis is meeting the above diagnostic criteria, but presenting normal mucosa at the 
oral-sided rectosigmoid (RS) in the endoscopy. 
[Note 6] Right-sided or segmental colitis is so difficult to be definitively differentiated from CD 
or colonic tuberculosis that it may be diagnosed in the course of follow-up or after 
acquisition of results of resection or autopsy. 
[Note 7] Diffuse gastroduodenitis may emerge.

B. Classification of the disease stages 
Active stage 
Remission stage 
[Note 8] The active stage is the condition where a patient may complain of rectal bleeding, the 
endoscopy may show an invisible vascular pattern, bleed easily, or have erosion, ulcer 
or the like. 
[Note 9] The remission stage is the condition where rectal bleeding may be resolved, and 
findings seen during the active stage may not be observed in the endoscopy with visible 
vascular pattern. 
C. Classification by clinical severity 
Mild 
Moderate 
Severe 
The diagnostic criteria is provided below; 
 
Severe 
Moderate 
Mild 
1) Stool frequency 
2) Overt bloody stool 
3) Fever 
4) Tachycardia 
5) Anemia 
6) Erythrocyte sedimentation 
≥6 
(+ + +) 
≥37.5°C 
≥90/min. 
≤Hb 10 g/dL 
≥30 mm/h 
Intermediate between  
sever and mild 
≤4 
(+) to (-) 
(-) 
(-) 
(-) 
Normal 
 
[Note 10] The (-) in the above 3), 4) and 5) in the Mild represents conditions without fever of 
≥37.5°C, tachycardia of ≥90/min., and anemia of ≤Hb 10 g/dL, respectively. 
[Note 11] The Severe should meet the above 1) and 2), and either 3) or 4) (for general condition), 
and at the same time meet ≥4 items in the 6 items. The Mild should meet all of the above 
6 items. 
[Note 12] The Moderate should be intermediate between the above Severe and Mild. 
[Note 13] The notably severe and serious disease in the Severe should be fulminating and 
categorized either to the acute fulminating type and the recurrent fulminating type in the 
course of development. All of the following 5 items should be met as the diagnostic 
criteria of the fulminating. 
(1) Fulfillment of the above severe criteria. 
(2) Continuous bloody diarrhea of ≥15/day 
(3) Continuous fever of ≥38°C

(4) Leukocytosis of ≥10,000/mm3 
(5) Severe abdominal pain 
D. Classification by findings on endoscopy during the active stage 
Mild 
Moderate 
Severe 
The diagnostic criteria is provided in the following table; 
Inflammation 
Findings on Endoscopy 
Mild 
Invisible vascular pattern 
Finely-granular mucosa 
Redness, aphtha, small yellowish spots 
Moderate 
Rough, erosive or small ulcerative mucosa 
Bleed easily (contact bleeding) 
Adhesion of viscous sanguinopurulent-secreted matters 
Other active inflammatory findings 
Severe 
Extensive ulcer 
Notable spontaneous hemorrhage 
 
[Note 14] The most severe lesion should be diagnosed in the entire endoscopically examined 
lesion. The endoscopy may be conducted in a short time without pretreatment and not 
necessarily examined over the entire colon. 
E. Classification by clinical course 
Relapse-remitting type 
Chronic continuous type 
Acute fulminating type 
First attack type 
[Note 15] The chronic continuous type is on the active stage for 6 month or more after the first 
attack. 
[Note 16] The acute fulminating type occurs with extremely fulminating symptoms, and may 
often be associated with complications including toxic megacolon, perforation or sepsis. 
[Note 17] The first attack type occurs only once, however, may recur in the future and mostly 
becomes the relapse-remitting type.

F. Particular classification by macroscopic findings 
Pseudopolyposis type 
Atrophic colitis type 
G. Definition of intractable UC based on treatment response 
1. A disease meeting either of the following despite a rigorous corticosteroid therapy. 
[1] Corticosteroid resistance (no response after treatment of 1 to 1.5 mg/kg/day of 
prednisolone for 1 to 2 weeks) 
[2] Corticosteroid dependence (recurrence during the course of dose reduction of the 
corticosteroid) 
2. A disease frequently recurs or appears to be the chronic continuous type despite rigorous 
medical treatment other than corticosteroid. 
H. Diagnostic criteria for pouchitis 
I. Overview 
Pouchitis is a non-specific inflammation occurring in the ileoanal pouch in patients who 
underwent innate anus-preserving total (subtotal) colectomy. Though etiology remains unknown, 
the disease may possibly be associated with pathogenesis of UC, as frequently occurs after 
UC-related surgeries and infrequently occurs after surgeries of familial adenomatous polyposis. 
II. Diagnoses of pouchitis 
1. Items 
a) Clinical symptoms 
1) Increase of stool frequency, 2) Rectal bleeding, 3) Defecation urgency or abdominal 
pain4) Fever (≥37.8°C) 
b) Findings on Endoscopy 
Mild: edema, granular mucosa, invisible vascular pattern, mild redness 
Moderate: aphtha, erosion, small ulcer#, bleed easily, viscous mucus 
Severe: extensive ulcer, multiple ulcer#, diffuse redness, spontaneous hemorrhage 
#: Staple line ulcer should be entered separately from other findings on endoscopy of pouchitis, 
unless other findings were observed. 
2. Diagnostic criteria 
Pouchitis is diagnosed when moderate or greater findings on endoscopy are found with at least 
one clinical symptom, or when severe findings on endoscopy were found with or without 
clinical symptoms. The diseases that should be ruled out include infectious enteritis (bacterial 
enteritis including salmonella enteritis, campylobacter enteritis and intestinal tuberculosis, viral 
enteritis including cytomegalovirus enteritis, and parasitosis), anastomotic leakage, pelvic 
infection, postoperative anal dysfunction and CD.

Appendix D PML Checklists 
• The PML checklists will be utilized in visits specified in the protocol, or for a subject 
complaining such symptoms. 
• The purpose of the PML checklists is to identify any obvious neurological changes in a subject 
since the last evaluation. 
• When any subjective symptoms were identified, the corresponding tests to see objective 
findings should be performed. Any symptoms/findings found on the checklists should be 
recorded as AEs. 
• Subjects should be instructed to visit a neurologist, when any obvious neurological changes 
were observed. Examinations including MRI using a contrast agent should be performed for 
collection of information supporting the neurological change, if needed. 
• Any positive subjective symptoms or positive objective findings should be provided to the 
sponsor immediately.
