Trelagliptin 
Alogliptin 
Study title: 
An exploratory study of the effects of trelagliptin and alogliptin on glycemic variation 
in patients with type 2 diabetes mellitus 
Protocol number: Trelagliptin-4001 (122/NRP-001) 
Clinical study design: 
This is a multi-center, randomized, open-label, parallel-group comparative, exploratory study to evaluate 
the effect of trelagliptin administered at a dose of 100 mg once weekly or alogliptin administered at a 
dose of 25 mg once daily for 4 weeks on glycemic variation in patients with type 2 diabetes mellitus using 
continuous glucose monitoring (CGM). 
After informed consent, patients determined to be eligible for this study based on the eligibility 
assessment will be randomized to either the trelagliptin 100 mg group or the alogliptin 25 mg group (at a 
ratio of 1:1), using "HbA1c at the start of the observation period (< 7.5% or ≥ 7.5%)" and age (< 65 or ≥ 
65) as a stratification factor for randomization. 
The total duration of evaluation will be 31 days, consisting of the observation period for 2 days and a 
treatment period for 29 days (4 weeks). CGM will be performed on research subjects on an outpatient 
basis (in 2 assessments) for 2 days from the start of the observation period (Day -2) and for 9 days from 
Day 21 of the treatment period. 
Objective:  
To evaluate the effect of trelagliptin administered orally at a dose of 100 mg once weekly or alogliptin 
administered orally at a dose of 25 mg once daily for 4 weeks on glycemic variation in an exploratory 
manner and as preliminary to examine the influence of the once-weekly administration and blood glucose 
fluctuations due to the difference in the daily administration in patients with type 2 diabetes mellitus 
Study population:  
Patients with type 2 diabetes mellitus 
Planned number of research subjects: 
The planned minimum number of research subjects evaluable

Statistical method 
(1) Analysis set 
Two analysis sets, “full analysis set” and “safety data analysis set” are used in this study. "The Full 
Analysis Set" used as a primary analysis set in the efficacy analysis shall be defined as "the research 
subjects who were randomized and given at least one dose of the study drug." The safety data 
analysis set shall be defined as “the research subjects who were given at least one dose of the study 
drug”. 
(2) Efficacy analysis 
<Primary endpoints> 
• 
For the “full analysis set”, summary statistics (number of subjects, mean, SDs, maximum values, 
minimum values, quartiles [same apply hereafter]) and 95% confidence interval (two sides) of mean 
shall be calculated for each treatment group at each evaluation point (each day), and illustrating 
changes in mean and SD in order to evaluate changes in the SD of 24-hour blood glucose values 
(mg/dL) for each 7-day period between Week 3 and Week 4 (between Day 22 and Day 28) of the 
treatment period, calculated from the value at the start of the observation period for trelagliptin or 
alogliptin separately. Preliminary, for the “full analysis set”, calculate point estimation and 95% 
confidence interval (two sides) in difference of mean in treatment groups (trelagliptin 100 mg group 
– alogliptin 25 mg group) in order to examine the influence of the once-weekly administration and 
blood glucose fluctuations due to the difference in the daily administration exploratory. 
• 
As well, for the “full analysis set ,” conduct analysis of covariance at each evaluation point with 
changes in the SD of 24-hour blood glucose values between Week 3 and Week 4 from the value at 
the start of the observation period as dependent variable, treatment groups as independent variable, 
HbA1c (NGSP value) at the start of the observation period, changes in the SD of 24-hour blood 
glucose values at the start of the observation period, and age as covariates, and calculate point 
estimation and 95% confidence interval (two sides) in difference of adjusted mean for each group. 
• 
Preliminary, “full analysis set ,” calculate point estimation and 95% confidence interval (two sides) 
in difference of adjusted mean in treatment groups (trelagliptin 100 mg group – alogliptin 25 mg 
group) 
<Secondary endpoints> 
• 
Conduct the same analysis as the primary endpoints for *1 and *2 of the each endpoint section.

INTRODUCTION 
4.1 
Background 
Conventionally, although HbA1c has been used as an indicator for glycemic control for patients with 
diabetes mellitus, it has been indicated that it is insufficient for inhibiting cardiovascular events by 
only controlling HbA1c which reflects the long term glycemic variation 1-3) On the other hand, it has 
been reported that persistent hyperglycemia and the range of glycemic variation is related to 
oxidative stress and cardiovascular events, and it has been indicated that treatment is necessary in 
consideration of daily glycemic variation 4-6). Also, it is anticipated that the glycemic variation of 
patients with diabetes mellitus and the characteristics of each anti-diabetic medications may be 
revealed and to be able to make a choice for a more appropriate treatment. 
Self-measurement of blood glucose (SMBG) is used frequently for measuring glycemic variation 
and although one may understand the blood glucose level at the time of measurement, it is difficult 
to know if the blood glucose level has an upward trend or not changing or a downward trend at that 
time point, and it is reported that 80% hypoglycemia or hyperglycemia may be missed 7,8). That is 
why the continuous glucose monitor (CGM) was developed and it became possible to accurately 
evaluate variance of blood glucose which was difficult and planning of treatment course according to 
each patient’s condition is anticipated. Actually, in many researches that was conducted to collect 
various glycemic variation patterns to verify the optimization of treatment of diabetes mellitus, the 
benefits of various indicators of glycemic variation obtained from CGM has been reported 9). 
Dipeptidyl-peptidase-4 (DPP-4) inhibitors are used widely as oral treatment drug for type 2 diabetes 
mellitus and it has an effect to promote insulin secretion blood glucose dependently by raising blood 
concentration of glucagon like peptide-1 (GLP-1). Conventionally, although DPP-4 inhibitors are 
taken once to twice daily commonly, once weekly trelagliptin was developed for a new treatment 
option as good glycemic control from improvement of drug compliance rate and flexibility of timing 
of taking drug according to lifestyle and further improvement of Quality Of Life(QOL) from less 
number of doses was in need. The phase III clinical study conducted at the development stage has 
shown that trelagliptin, when administered for 24 weeks, was not inferior to alogliptin, a DPP-4 
inhibitor used as control, in terms of the change in HbA1c at the end of the treatment period 10). 
However, effect on glycemic variation of trelagliptin and alogliptin has not been clarified efficiently, 
and it is anticipated that understanding the characteristics of once weekly DPP-4 inhibitors and once 
daily DPP-4 inhibitors may be an efficient rational for therapeutic use.

Because there is no enough evidence assayed for glycemic variation of not only once weekly DPP-4 
inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, and 
Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive data of 
glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhibitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period, the effect on glycemic variation of alogliptin have to be clarified when the effect of different 
dose and method of administration of DPP-4 inhibitors on glycemic variation would like to be 
evaluated. 
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administration on 
glycemic variation will be evaluated as secondary as far as possible.

6.2 
Rationale for the clinical research design 
(1) Rationale for the clinical research design 
  
Because there is no enough evidence assayed for glycemic variation of not only once weekly 
DPP-4 inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, 
and Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive 
data of glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhibitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period,  the effect on glycemic variation of alogliptin have to be clarified when the effect of 
different dose and method of administration of DPP-4 inhibitors on glycemic variation would like 
to be evaluated.  
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administration 
on glycemic variation will be evaluated as secondary as far as possible.

Therefore this unblind study was designed to objectively evaluate the effect on glycemic variation of 
trelagliptin 100 mg and alogliptin 25 mg administered in patients with type 2 diabetes mellitus. And 
also to evaluate the effect of different method of administration on glycemic variation, stratified 
randomization comparison method between 2 groups was adopted with “HbA1c at the start of the 
observation period (< 7.5% or ≥ 7.5%) and age (< 65 or ≥ 65)” as a stratification factor for 
randomization. 
Also, to exclude effect on glycemic variation from other anti-diabetic medications, research 
subjects who were taking anti-diabetic medications ≤ 4 weeks before start of observation period 
were excluded. 
(2) Rationale for dosage 
The dosages of trelagliptin and alogliptin were set at 100 mg/week and 25 mg/day, respectively, 
to evaluate glycemic variation at the usual dosage in clinical settings.  
(3) Rationale for dosage 
Study drugs show the glucose lowering effect by increasing incretin which are secreted by food 
intake. Thus, in order to eliminate the influence on the blood glucose by food intake. To further 
unify the administration timing of the research subjects prior to breakfast in terms of evaluating 
their glycemic variation. 
(4) Rationale for duration of treatment 
From the results of trelagliptin and alogliptin in phase II and III trials, duration was set at 4 
weeks taking into account that the effect on blood glucose levels stabilize after 2 to 4 weeks 
with either drugs. 
(5) Rationale for the number of planned research subjects: 
Refer section 13.3

9.1.6 Concurrent disease 
A concurrent disease is defined as a disease or symptom that is present at the start of the observation 
period or that develops between the start of the observation period and the start of study treatment. 
Clinically significant abnormalities, including laboratory test data and physical examination findings, 
observed in tests and physical examinations at the start of study treatment shall be considered as a 
concurrent disease at the discretion of the principal investigator or investigator. The content of 
concurrent disease (diagnosis) shall be investigated. 
9.1.7 Laboratory tests

10.0 
ADVERSE EVENT 
10.1 
Definitions 
10.1.1 Adverse event 
An adverse event is defined as any untoward medical occurrence in a patient or a research subject 
receiving a pharmaceutical product (including the study drug). It does not necessarily have an 
apparent causal relationship with this pharmaceutical product (including study drug). 
An adverse event can therefore be any unfavorable or unintended sign (e.g., clinically significant 
laboratory abnormality), symptom, or disease temporally associated with the use of a pharmaceutical 
product (including the study drug), regardless of whether it is considered related to the 
pharmaceutical product (including the study drug) or not. 
10.1.2 Considerations for adverse events 
Generally unfavorable findings are described below: 
• 
Newly diagnosed disease or unexpected aggravation of existing symptom (intermittent 
event of an existing symptom is not considered an adverse event) 
• 
Requiring action or medical practice 
• 
Requiring invasive diagnostic treatment 
• 
Requiring discontinuation or a change in the dose of the study drug or a concomitant 
medication 
• 
Considered unfavorable by the principal investigator or the investigator 
Diagnosis name and signs/symptoms: 
Adverse events shall be recorded by diagnosis name. Accompanying signs (including abnormal 
laboratory values, abnormal ECG findings) and symptoms shall not be recorded as adverse events. If 
an adverse event could not be expressed by a diagnosis name, the signs or symptoms shall be 
recorded as the adverse event. 
Laboratory test values and ECG findings: 
Abnormal laboratory values and ECG findings shall be recorded as adverse events when the 
principal investigator or investigator judges the results are clinically problematic (in other words, 
when certain action or medical practice is required, or when the principal investigator or the 
investigator judges the change has exceeded the normal physiological variation range of the research 
subject). Retest and/or continued monitoring of an abnormality are not considered medical practice. 

122/NRP-001 
"Protocol No. Trelagliptin-4001"  
Page 43 of 72
3nd Version 
February 16, 2017
 
CONFIDENTIAL 
Also, repeated or additional conduction of non-invasive tests for verification, evaluation, and 
monitoring of an abnormality are not considered medical practice. 
However, when abnormal laboratory values and ECG findings are the accompanying symptoms of a 
disease diagnosed as an adverse event (e.g., increased creatinine due to renal dysfunction, etc.), the 
adverse event shall be handled by its diagnosis name. 
Pre-existing conditions (disease or symptom that has been present since before the start of study 
treatment): Pre-existing disease or symptom that has been present since before the start of study 
treatment shall be regarded as a concurrent disease and not an adverse event. When a concurrent 
medical condition is aggravated, the aggravation shall be determined as an adverse event and the 
principal investigator or the investigator shall record on the CRF that the adverse event is an 
aggravation of the concurrent disease (e.g., “aggravation of hypertension,” etc.). 
If a research subject has a pre-existing episodic condition (e.g., asthma, epilepsy), each episode shall 
be recorded as an adverse event if the episodes become more frequent, serious, or severe in nature. If 
a research subject has a chronic concurrent condition (e.g., cataracts, rheumatoid arthritis), 
worsening of the condition shall be recorded as adverse event if the degree of the worsening exceeds 
that which would be expected. The principal investigator or investigator shall ensure that the adverse 
event term to be recorded represents the change in the condition from baseline (e.g. “worsening 
of…”). 
Worsening of adverse events:  
If a research subject experiences a worsening of the adverse event after a change to the study drug, 
or secondary signs and symptoms are caused by the adverse event, the worsening or the secondary 
signs and symptoms shall be recorded as a new adverse event on the CRF. The principal investigator 
or investigator shall use an adverse event term that explicitly means a change of the condition (e.g., 
“worsening of…”). 
Change of severity of adverse events:  
If the research subject experiences changes in the severity of an adverse event, the event shall be 
recorded once, at its peak severity. 
Previously planned surgery or treatment:  
Preplanned surgeries or interventions that were scheduled before study treatment shall not be 
considered adverse events. However, when the existing symptom is aggravated to a degree requiring 
emergency surgery or treatment, the condition or the event shall be considered an adverse event. A 
concurrent disease that resulted from previously planned surgery shall be reported as an adverse 
event.

Non-urgent surgery or treatment:  
Non-urgent surgery or treatment that does not induce a change in the condition of a research subject 
(cosmetic surgery, etc.) shall not be considered an adverse event; However, it shall be recorded in 
the source documents. Concurrent diseases due to a non-urgent surgery shall be reported as an 
adverse event. 
The insufficient clinical response (lack of efficacy): insufficient clinical response, efficacy, or 
pharmacological action shall not be recorded as an adverse event. The principal investigator or 
investigator shall make the distinction between worsening of a pre-existing condition and lack of 
therapeutic efficacy. 
Overdose of the study drug:  
Overdose of any medication without onset of event shall not be recorded as an adverse event, but the 
overdose shall be recorded on the “Overdose” page of the CRF. Any onset of event shall be recorded 
as adverse events on the “Adverse events” of the CRF. 
10.1.3 Serious adverse event 
Of all unfavorable medical events that develop after administration of a pharmaceutical product 
(including the study drug) (irrespective of dose), a serious adverse event is an event that: 
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, or 
6. Medically important event that causes a risk to the research subject even if it is not 
immediately life-threatening and does not result in death or hospitalization, or requires an 
action or treatment to prevent the results described in 1 to 5 above. Points described in the 
Takeda Medically Significant Adverse Event List (Table 10.a 
) are included in this 
section. 
* The term “life threatening” refers to an event in which the research subject was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have caused death if it 
were more severe.

10.1.4 Adverse events of special interest (specific adverse events) 
An AE of Special Interest (AESI) (serious or non-serious) is one of scientific and medical concern 
specific to the study drug, for which ongoing monitoring and rapid communication by the principal 
investigator or investigator to Takeda may be appropriate. Such events may require further 
investigation in order to establish assessment, and instructions provided to investigators on how and 
when they should be reported to the sponsor are described in Section 10.2.1.3. 
AESIs: Hypoglycemia-related AEs, intestinal obstruction-related AEs and acute pancreatitis-related 
AEs (for both Trelagliptin and Alogliptin), QT/QTc interval prolongation-related AEs (for 
Trelagliptin), and Liver dysfunction or jaundice-related AEs (for Alogliptin). 
<For both Trelagliptin and Alogliptin> 
[Hypoglycemia-related AEs] 
Hypoglycemia-related AEs are designated as AESIs because, in general, attention should be paid to 
the events in the treatment of diabetes mellitus. 
[Intestinal obstruction-related AEs] 
Intestinal obstruction-related AEs are designated as AESIs because there are accumulated reports of 
intestinal obstruction as an adverse reaction to similar incretin-related drugs (GLP-1 receptor 
agonists and other DPP-4 inhibitors). 
[Acute pancreatitis-related AEs]

adverse event irrespective of the causal relationship with the study drug, until the symptom resolves, 
or any clinically significant abnormal laboratory values have returned to baseline or there is a 
satisfactory explanation for the change (permanent or irreversible adverse events). All adverse 
events shall be entered on the CRF. Adverse event term, onset date, resolution date, severity, causal 
relationship with the study drug (i.e. "Unrelated" or "Related"), action taken for the study drug, 
outcome, causal relationship with any study procedure (with specific procedure if assessed to be 
causally related), and seriousness shall be entered.

Study drug: 
Trelagliptin 
Alogliptin 
Study title: 
An exploratory study of the effects of trelagliptin and alogliptin on glycemic variation 
in patients with type 2 diabetes mellitus 
Protocol number: Trelagliptin-4001 (122/NRP-001) 
Clinical study design: 
This is a multi-center, randomized, open-label, parallel-group comparative, exploratory study to evaluate 
the effect of trelagliptin administered at a dose of 100 mg once weekly or alogliptin administered at a 
dose of 25 mg once daily for 4 weeks on glycemic variation in patients with type 2 diabetes mellitus using 
continuous glucose monitoring (CGM). 
After informed consent, patients determined to be eligible for this study based on the eligibility 
assessment will be randomized to either the trelagliptin 100 mg group or the alogliptin 25 mg group (at a 
ratio of 1:1), using "HbA1c at the start of the observation period (< 7.5% or ≥ 7.5%)" and age (< 65 or ≥ 
65) as a stratification factor for randomization. 
The total duration of evaluation will be 31 days, consisting of the observation period for 2 days and a 
treatment period for 29 days (4 weeks). CGM will be performed on research subjects on an outpatient 
basis (in 2 assessments) for 2 days from the start of the observation period (Day -2) and for 9 days from 
Day 21 of the treatment period. 
Objective:  
To evaluate the effect of trelagliptin administered orally at a dose of 100 mg once weekly or alogliptin 
administered orally at a dose of 25 mg once daily for 4 weeks on glycemic variation in an exploratory 
manner and as preliminary to examine the influence of the once-weekly administration and blood glucose 
fluctuations due to the difference in the daily administration in patients with type 2 diabetes mellitus 
Study population:  
Patients with type 2 diabetes mellitus

Statistical method 
(1) Analysis set 
Two analysis sets, “full analysis set” and “safety data analysis set” are used in this study. "The Full 
Analysis Set" used as a primary analysis set in the efficacy analysis shall be defined as "the research 
subjects who were randomized and given at least one dose of the study drug." The safety data 
analysis set shall be defined as “the research subjects who were given at least one dose of the study 
drug”. 
(2) Efficacy analysis 
<Primary endpoints> 
• 
For the “full analysis set”, summary statistics (number of subjects, mean, SDs, maximum values, 
minimum values, quartiles [same apply hereafter]) and 95% confidence interval (two sides) of mean 
shall be calculated for each treatment group at each evaluation point (each day), and illustrating 
changes in mean and SD in order to evaluate changes in the SD of 24-hour blood glucose values 
(mg/dL) for each 7-day period between Week 3 and Week 4 (between Day 22 and Day 28) of the 
treatment period, calculated from the value at the start of the observation period for trelagliptin or 
alogliptin separately. Preliminary, for the “full analysis set”, calculate point estimation and 95% 
confidence interval (two sides) in difference of mean in treatment groups (trelagliptin 100 mg group 
– alogliptin 25 mg group) in order to examine the influence of the once-weekly administration and 
blood glucose fluctuations due to the difference in the daily administration exploratory. 
• 
As well, for the “full analysis set ,” conduct analysis of covariance at each evaluation point with 
changes in the SD of 24-hour blood glucose values between Week 3 and Week 4 from the value at 
the start of the observation period as dependent variable, treatment groups as independent variable, 
HbA1c (NGSP value) at the start of the observation period, changes in the SD of 24-hour blood 
glucose values at the start of the observation period, and age as covariates, and calculate point 
estimation and 95% confidence interval (two sides) in difference of adjusted mean for each group. 
• 
Preliminary, “full analysis set ,” calculate point estimation and 95% confidence interval (two sides) 
in difference of adjusted mean in treatment groups (trelagliptin 100 mg group – alogliptin 25 mg 
group) 
<Secondary endpoints> 
• 
Conduct the same analysis as the primary endpoints for *1 and *2 of the each endpoint section.

However, for changes in mean/SD, only measured values of *1 and *2 shall be illustrated. 
<Additional endpoints> 
• For the “full analysis set”, while calculating summary statistics and 95% confidence interval (two 
sides) of mean at each evaluation point (the start of the observation period by each treatment group, 
first day, 1 point during fourth to sixth day, and ninth day of CGM which is to be performed for 9 
days from Day 21) in measured values and changes from the start of the observation period, and 
illustrate changes in mean and SD. 
(3) Safety analysis 
• Adverse events shall be reported using MedDRA terminology and summarized using the Preferred 
Term (PT) and System Organ Class (SOC) of the MedDRA. For the “safety data analysis set”, 
frequency tabulation shall be conducted for adverse events after start of treatment with study drug by 
each treatment group: 
 
Frequency tabulation of all adverse events 
 
Frequency tabulation of adverse events that causal relationship is “related” to study drug. 
 
Frequency tabulation of the degree of all adverse events 
 
Frequency tabulation of degree of adverse events that causal relationship is “related” to study 
drug. 
 
Frequency tabulation of adverse events that were “discontinued” as a measurement concerning 
study drug. 
 
Frequency tabulation of serious adverse events 
Rationale for the number of planned research subjects: 
The planned minimum number of research subjects evaluable for the primary endpoint in each group is as 
follows: 
Trelagliptin 100 mg group: 15 
Alogliptin 25 mg group: 15 
Set in consideration with the feasibility of the number of research subjects for exploring the effects of 
trelagliptin 100 mg and alogliptin 25 mg on glycemic variation. It is not based on statistical power 
calculation.

INTRODUCTION 
4.1 
Background 
Conventionally, although HbA1c has been used as an indicator for glycemic control for patients with 
diabetes mellitus, it has been indicated that it is insufficient for inhibiting cardiovascular events by 
only controlling HbA1c which reflects the long term glycemic variation 1-3) On the other hand, it has 
been reported that persistent hyperglycemia and the range of glycemic variation is related to 
oxidative stress and cardiovascular events, and it has been indicated that treatment is necessary in 
consideration of daily glycemic variation 4-6). Also, it is anticipated that the glycemic variation of 
patients with diabetes mellitus and the characteristics of each anti-diabetic medications may be 
revealed and to be able to make a choice for a more appropriate treatment. 
Self-measurement of blood glucose (SMBG) is used frequently for measuring glycemic variation 
and although one may understand the blood glucose level at the time of measurement, it is difficult 
to know if the blood glucose level has an upward trend or not changing or a downward trend at that 
time point, and it is reported that 80% hypoglycemia or hyperglycemia may be missed 7,8). That is 
why the continuous glucose monitor (CGM) was developed and it became possible to accurately 
evaluate variance of blood glucose which was difficult and planning of treatment course according to 
each patient’s condition is anticipated. Actually, in many researches that was conducted to collect 
various glycemic variation patterns to verify the optimization of treatment of diabetes mellitus, the 
benefits of various indicators of glycemic variation obtained from CGM has been reported 9). 
Dipeptidyl-peptidase-4 (DPP-4) inhibitors are used widely as oral treatment drug for type 2 diabetes 
mellitus and it has an effect to promote insulin secretion blood glucose dependently by raising blood 
concentration of glucagon like peptide-1 (GLP-1). Conventionally, although DPP-4 inhibitors are 
taken once to twice daily commonly, once weekly trelagliptin was developed for a new treatment 
option as good glycemic control from improvement of drug compliance rate and flexibility of timing 
of taking drug according to lifestyle and further improvement of Quality Of Life(QOL) from less 
number of doses was in need. The phase III clinical study conducted at the development stage has 
shown that trelagliptin, when administered for 24 weeks, was not inferior to alogliptin, a DPP-4 
inhibitor used as control, in terms of the change in HbA1c at the end of the treatment period 10). 
However, effect on glycemic variation of trelagliptin and alogliptin has not been clarified efficiently, 
and it is anticipated that understanding the characteristics of once weekly DPP-4 inhibitors and once 
daily DPP-4 inhibitors may be an efficient rational for therapeutic use.

Because there is no enough evidence assayed for glycemic variation of not only once weekly DPP-4 
inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, and 
Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive data of 
glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhibitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period, the effect on glycemic variation of alogliptin have to be clarified when the effect of different 
dose and method of administration of DPP-4 inhibitors on glycemic variation would like to be 
evaluated. 
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administration on 
glycemic variation will be evaluated as secondary as far as possible.

6.2 
Rationale for the clinical research design 
(1) Rationale for the clinical research design 
  
Because there is no enough evidence assayed for glycemic variation of not only once weekly 
DPP-4 inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, 
and Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive 
data of glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhibitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period, the effect on glycemic variation of alogliptin have to be clarified when the effect of 
different dose and method of administration of DPP-4 inhibitors on glycemic variation would like 
to be evaluated.  
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administration 
on glycemic variation will be evaluated as secondary as far as possible.

Therefore this unblind study was designed to objectively evaluate the effect on glycemic variation of 
trelagliptin 100 mg and alogliptin 25 mg administered in patients with type 2 diabetes mellitus. And 
also to evaluate the effect of different method of administration on glycemic variation, stratified 
randomization comparison method between 2 groups was adopted with “HbA1c at the start of the 
observation period (< 7.5% or ≥ 7.5%) and age (< 65 or ≥ 65)” as a stratification factor for 
randomization. 
Also, to exclude effect on glycemic variation from other anti-diabetic medications, research 
subjects who were taking anti-diabetic medications ≤ 4 weeks before start of observation period 
were excluded. 
(2) Rationale for dosage 
The dosages of trelagliptin and alogliptin were set at 100 mg/week and 25 mg/day, respectively, 
to evaluate glycemic variation at the usual dosage in clinical settings.  
(3) Rationale for dosage 
Study drugs show the glucose lowering effect by increasing incretin which are secreted by food 
intake. Thus, in order to eliminate the influence on the blood glucose by food intake. To further 
unify the administration timing of the research subjects prior to breakfast in terms of evaluating 
their glycemic variation. 
(4) Rationale for duration of treatment 
From the results of trelagliptin and alogliptin in phase II and III trials, duration was set at 4 
weeks taking into account that the effect on blood glucose levels stabilize after 2 to 4 weeks 
with either drugs. 
(5) Rationale for the number of planned research subjects: 
Refer section 13.3

9.1.12 for discontinuation case before randomization. 
1. Adverse event 
When the research subject had an adverse event that requires withdrawal of the research subject 
from the study because continued participation in the study would impose an unacceptable risk 
to the research subject’s health, or when the research subject is unwilling to continue study 
participation because of the pretreatment event or adverse event. 
2. Major protocol deviation 
When it is discovered after randomization that a research subject does not meet the eligibility 
criteria or is not adhering to the protocol, and continued participation in the research would 
impose an unacceptable risk to the research subject’s health.  
3. Lost to follow-up 
When the research subject failed to make visits and could not be contacted. The attempts that 
were made to contact the research subject shall be recorded in the source documents.

administration) other than the allocated oral hypoglycemic drug, from start of observation period to 
the completion of the clinical research shall be monitored. 
9.1.6 Concurrent disease 
A concurrent disease is defined as a disease or symptom that is present at the start of the observation 
period or that develops between the start of the observation period and the start of study treatment. 
Clinically significant abnormalities, including laboratory test data and physical examination findings, 
observed in tests and physical examinations at the start of study treatment shall be considered as a 
concurrent disease at the discretion of the principal investigator or investigator. The content of 
concurrent disease (diagnosis) shall be investigated. 
9.1.7 Laboratory tests 
Laboratory tests in table 9.a shall be measured at clinical laboratory institutions according to the 
observation schedule (Appendix A). Regarding tests at fasting, blood sampling shall be conducted 
after ≥ 10 hours of fasting. The principal investigator and investigator shall evaluate and keep the 
reported laboratory test results. 
Inhibitory rate of DPP-4 activity will be calculated by the sponsor using formula below: 
Inhibitory rate of DPP-4 activity (%) = (DPP-4 activity at start of observation period – DPP-4 
activity at each visit of treatment period) / DPP-4 activity at start of observation period x 100

ADVERSE EVENT 
10.1 
Definitions 
10.1.1 Adverse event 
An adverse event is defined as any untoward medical occurrence in a patient or a research subject 
receiving a pharmaceutical product (including the study drug). It does not necessarily have an 
apparent causal relationship with this pharmaceutical product (including study drug). 
An adverse event can therefore be any unfavorable or unintended sign (e.g., clinically significant 
laboratory abnormality), symptom, or disease temporally associated with the use of a pharmaceutical 
product (including the study drug), regardless of whether it is considered related to the 
pharmaceutical product (including the study drug) or not. 
10.1.2 Considerations for adverse events 
Generally unfavorable findings are described below: 
• 
Newly diagnosed disease or unexpected aggravation of existing symptom (intermittent 
event of an existing symptom is not considered an adverse event) 
• 
Requiring action or medical practice 
• 
Requiring invasive diagnostic treatment 
• 
Requiring discontinuation or a change in the dose of the study drug or a concomitant 
medication 
• 
Considered unfavorable by the principal investigator or the investigator 
Diagnosis name and signs/symptoms: 
Adverse events shall be recorded by diagnosis name. Accompanying signs (including abnormal 
laboratory values, abnormal ECG findings) and symptoms shall not be recorded as adverse events. If 
an adverse event could not be expressed by a diagnosis name, the signs or symptoms shall be 
recorded as the adverse event. 
Laboratory test values and ECG findings: 
Abnormal laboratory values and ECG findings shall be recorded as adverse events when the 
principal investigator or investigator judges the results are clinically problematic (in other words, 
when certain action or medical practice is required, or when the principal investigator or the 
investigator judges the change has exceeded the normal physiological variation range of the research 
subject). Retest and/or continued monitoring of an abnormality are not considered medical practice. 

122/NRP-001 
"Protocol No. Trelagliptin-4001"  
Page 43 of 72
2nd Version 
November 11, 2016
 
CONFIDENTIAL 
Also, repeated or additional conduction of non-invasive tests for verification, evaluation, and 
monitoring of an abnormality are not considered medical practice. 
However, when abnormal laboratory values and ECG findings are the accompanying symptoms of a 
disease diagnosed as an adverse event (e.g., increased creatinine due to renal dysfunction, etc.), the 
adverse event shall be handled by its diagnosis name. 
Pre-existing conditions (disease or symptom that has been present since before the start of study 
treatment): Pre-existing disease or symptom that has been present since before the start of study 
treatment shall be regarded as a concurrent disease and not an adverse event. When a concurrent 
medical condition is aggravated, the aggravation shall be determined as an adverse event and the 
principal investigator or the investigator shall record on the CRF that the adverse event is an 
aggravation of the concurrent disease (e.g., “aggravation of hypertension,” etc.). 
If a research subject has a pre-existing episodic condition (e.g., asthma, epilepsy), each episode shall 
be recorded as an adverse event if the episodes become more frequent, serious, or severe in nature. If 
a research subject has a chronic concurrent condition (e.g., cataracts, rheumatoid arthritis), 
worsening of the condition shall be recorded as adverse event if the degree of the worsening exceeds 
that which would be expected. The principal investigator or investigator shall ensure that the adverse 
event term to be recorded represents the change in the condition from baseline (e.g. “worsening 
of…”). 
Worsening of adverse events :  
If a research subject experiences a worsening of the adverse event after a change to the study drug, 
or secondary signs and symptoms are caused by the adverse event, the worsening or the secondary 
signs and symptoms shall be recorded as a new adverse event on the CRF. The principal investigator 
or investigator shall use an adverse event term that explicitly means a change of the condition (e.g., 
“worsening of…”). 
Change of severity of adverse events:  
If the research subject experiences changes in the severity of an adverse event, the event shall be 
recorded once, at its peak severity. 
Previously planned surgery or treatment:  
Preplanned surgeries or interventions that were scheduled before study treatment shall not be 
considered adverse events. However, when the existing symptom is aggravated to a degree requiring 
emergency surgery or treatment, the condition or the event shall be considered an adverse event. A 
concurrent disease that resulted from previously planned surgery shall be reported as an adverse 
event.

November 11, 2016
 
CONFIDENTIAL 
Non-urgent surgery or treatment:  
Non-urgent surgery or treatment that does not induce a change in the condition of a research subject 
(cosmetic surgery, etc.) shall not be considered an adverse event; However, it shall be recorded in 
the source documents. Concurrent diseases due to a non-urgent surgery shall be reported as an 
adverse event. 
The insufficient clinical response (lack of efficacy): insufficient clinical response, efficacy, or 
pharmacological action shall not be recorded as an adverse event. The principal investigator or 
investigator shall make the distinction between worsening of a pre-existing condition and lack of 
therapeutic efficacy. 
Overdose of the study drug:  
Overdose of any medication without onset of event shall not be recorded as an adverse event, but the 
overdose shall be recorded on the “Overdose” page of the CRF. Any onset of event shall be recorded 
as adverse events on the “Adverse events” of the CRF. 
10.1.3 Serious adverse event 
Of all unfavorable medical events that develop after administration of a pharmaceutical product 
(including the study drug) (irrespective of dose), a serious adverse event is an event that: 
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, or

10.1.4 Adverse events of special interest (specific adverse events) 
An AE of Special Interest (AESI) (serious or non-serious) is one of scientific and medical concern 
specific to the study drug, for which ongoing monitoring and rapid communication by the principal 
investigator or investigator to Takeda may be appropriate. Such events may require further 
investigation in order to establish assessment, and instructions provided to investigators on how and 
when they should be reported to the sponsor are described in Section 10.2.1.3. 
AESIs: Hypoglycemia-related AEs, intestinal obstruction-related AEs and acute pancreatitis-related 
AEs (for both Trelagliptin and Alogliptin), QT/QTc interval prolongation-related AEs (for 
Trelagliptin), and Liver dysfunction or jaundice-related AEs (for Alogliptin). 
<For both Trelagliptin and Alogliptin> 
[Hypoglycemia-related AEs] 
Hypoglycemia-related AEs are designated as AESIs because, in general, attention should be paid to 
the events in the treatment of diabetes mellitus. 
[Intestinal obstruction-related AEs] 
Intestinal obstruction-related AEs are designated as AESIs because there are accumulated reports of 
intestinal obstruction as an adverse reaction to similar incretin-related drugs (GLP-1 receptor 
agonists and other DPP-4 inhibitors). 
[Acute pancreatitis-related AEs]

Acute pancreatitis-related AEs are designated as AESIs because there are accumulated reports of 
acute pancreatitis as an adverse reaction to similar incretin-related drugs. 
<For Trelagliptin> 
[QT/QTc interval prolongation-related AEs] 
QT/QTc interval prolongation-related AEs are designated as AESIs because, in the QT/QTc 
assessment study conducted during the development, QT/QTc interval prolongation was reported in 
the trelagliptin 800 mg group although it did not occur in the trelagliptin 200 mg group. 
<For Alogliptin>

parameter. 
10.1.9 Date of resolution 
The date of resolution of an adverse event is the date on which the research subject recovered 
(including resolution with sequelae). If a research subject died due to the adverse event concerned, it 
shall be the date of death. The adverse event shall be recorded as “ongoing” if the research subject 
has not yet recovered by the end of the study. 
10.1.10 Actions taken for the study drug 
Actions taken for the study drug shall be classified or defined as shown below.

“Direct relationship” means that the concerned adverse event was the cause of 
death, or the concerned adverse event was clearly responsible for death. 
Outcome of an adverse event which was not determined (judged, presumed) a direct 
cause of death observed in the same research subject is not considered as death.

STUDY SUMMARY 
Sponsor: 
Takeda Pharmaceutical Company Limited 
Study drug: 
Trelagliptin 
Alogliptin 
Study title: 
An exploratory study of the effects of trelagliptin and alogliptin on glycemic variation 
in patients with type 2 diabetes mellitus 
Protocol number: Trelagliptin-4001 (122/NRP-001) 
Clinical study design: 
This is a multi-center, randomized, open-label, parallel-group comparative, exploratory study to evaluate 
the effect of trelagliptin administered at a dose of 100 mg once weekly or alogliptin administered at a 
dose of 25 mg once daily for 4 weeks on glycemic variation in patients with type 2 diabetes mellitus using 
continuous glucose monitoring (CGM). 
After informed consent, patients determined to be eligible for this study based on the eligibility 
assessment will be randomized to either the trelagliptin 100 mg group or the alogliptin 25 mg group (at a 
ratio of 1:1), using "HbA1c at the start of the observation period (< 7.5% or ≥ 7.5%)" and age (< 65 or ≥ 
65) as a stratification factor for randomization. 
The total duration of evaluation will be 31 days, consisting of the observation period for 2 days and a 
treatment period for 29 days (4 weeks). CGM will be performed on research subjects on an outpatient 
basis (in 2 assessments) for 2 days from the start of the observation period (Day -2) and for 9 days from 
Day 21 of the treatment period. 
Objective:  
To evaluate the effect of trelagliptin administered orally at a dose of 100 mg once weekly or alogliptin 
administered orally at a dose of 25 mg once daily for 4 weeks on glycemic variation in an exploratory 
manner and as preliminary to examine the influence of the once-weekly administration and blood glucose 
fluctuations due to the difference in the daily administration in patients with type 2 diabetes mellitus 
Study population:  
Patients with type 2 diabetes mellitus 
Planned number of research subjects: 
The planned minimum number of research subjects evaluable

Statistical method 
(1) Analysis set 
Two analysis sets, “full analysis set” and “safety data analysis set” are used in this study. "The Full 
Analysis Set" used as a primary analysis set in the efficacy analysis shall be defined as "the research 
subjects who were randomized and given at least one dose of the study drug." The safety data 
analysis set shall be defined as “the research subjects who were given at least one dose of the study 
drug”. 
(2) Efficacy analysis 
<Primary endpoints> 
• 
For the “full analysis set”, summary statistics (number of subjects, mean, SDs, maximum values, 
minimum values, quartiles [same apply hereafter]) and 95% confidence interval (two sides) of mean 
shall be calculated for each treatment group at each evaluation point (each day), and illustrating 
changes in mean and SD in order to evaluate changes in the SD of 24-hour blood glucose values 
(mg/dL) for each 7-day period between Week 3 and Week 4 (between Day 22 and Day 28) of the 
treatment period, calculated from the value at the start of the observation period for treagliptin or 
alogliptin separately.Preliminary, for the “full analysis set”, calculate point estimation and 95% 
confidence interval (two sides) in difference of mean in treatment groups (trelagliptin 100 mg group 
– alogliptin 25 mg group) in order to examine the influence of the once-weekly administration and 
blood glucose fluctuations due to the difference in the daily administration exploratory. 
• 
As well, for the “full analysis set ,” conduct analysis of covariance at each evaluation point with 
changes in the SD of 24-hour blood glucose values between Week 3 and Week 4 from the value at 
the start of the observation period as dependent variable, treatment groups as independent variable, 
HbA1c (NGSP value) at the start of the observation period, changes in the SD of 24-hour blood 
glucose values at the start of the observation period, and age as covariates, and calculate point 
estimation and 95% confidence interval (two sides) in difference of adjusted mean for each group. 
• 
Preliminary, “full analysis set ,” calculate point estimation and 95% confidence interval (two sides) 
in difference of adjusted mean in treatment groups (trelagliptin 100 mg group – alogliptin 25 mg 
group) 
Secondary endpoints 
• 
Conduct the same analysis as the primary endpoints for *1 and *2 of the each endpoint section. 
However, for changes in mean/SD, only measured values of *1 and *2 shall be illustrated.

• For the “full analysis set”, while calculating summary statistics and 95% confidence interval (two 
sides) of mean at each evaluation point (the start of the observation period by each treatment group, 
first and ninth of CGM which is to be performed for 9 days from Day 21) in measured values and 
changes from the start of the observation period, and illustrate changes in mean and SD. 
(3) Safety analysis 
• Adverse events shall be reported using MedDRA terminology and summarized using the Preferred 
Term (PT) and System Organ Class (SOC) of the MedDRA. For the “safety data analysis set”, 
frequency tabulation shall be conducted for adverse events after start of treatment with study drug by 
each treatment group: 
 
Frequency tabulation of all adverse events 
 
Frequency tabulation of adverse events that causal relationship is “related” to study drug. 
 
Frequency tabulation of the degree of all adverse events 
 
Frequency tabulation of degree of adverse events that causal relationship is “related” to study 
drug. 
 
Frequency tabulation of adverse events that were “discontinued” as a measurement concerning 
study drug. 
 
Frequency tabulation of serious adverse events 
Rationale for the number of planned research subjects: 
The planned minimum number of research subjects evaluable for the primary endpoint in each group is as 
follows: 
Trelagliptin 100 mg group: 15 
Alogliptin 25 mg group: 15 
Set in consideration with the feasibility of the number of research subjects for exploring the effects of 
trelagliptin 100 mg and alogliptin 25 mg on glycemic variation. It is not based on statistical power 
calculation.

4.1 
Background 
Conventionally, although HbA1c has been used as an indicator for glycemic control for patients with 
diabetes mellitus, it has been indicated that it is insufficient for inhibiting cardiovascular events by 
only controlling HbA1c which reflects the long term glycemic variation1-3) On the other hand, it has 
been reported that persistent hyperglycemia and the range of glycemic variation is related to 
oxidative stress and cardiovascular events, and it has been indicated that treatment is necessary in 
consideration of daily glycemic variation4-6). Also, it is anticipated that the glycemic variation of 
patients with diabetes mellitus and the characteristics of each anti-diabetic medications may be 
revealed and to be able to make a choice for a more appropriate treatment. 
Self-measurement of blood glucose (SMBG) is used frequently for measuring glycemic variation 
and although one may understand the blood glucose level at the time of measurement, it is difficult 
to know if the blood glucose level has an upward trend or not changing or a downward trend at that 
time point, and it is reported that 80% hypoglycemia or hyperglycemia may be missed7,8). That is 
why the continuous glucose monitor (CGM) was developed and it became possible to accurately 
evaluate variance of blood glucose which was difficult and planning of treatment course according to 
each patient’s condition is anticipated. Actually, in many researches that was conducted to collect 
various glycemic variation patterns to verify the optimization of treatment of diabetes mellitus, the 
benefits of various indicators of glycemic variation obtained from CGM has been reported9). 
Dipeptidyl-peptidase-4 (DPP-4) inhibitors are used widely as oral treatment drug for type 2 diabetes 
mellitus and it has an effect to promote insulin secretion blood glucose dependently by raising blood 
concentration of glucagon like peptide-1 (GLP-1). Conventionally, although DPP-4 inhibitors are 
taken once to twice daily commonly, once weekly trelagliptin was developed for a new treatment 
option as good glycemic control from improvement of drug compliance rate and flexibility of timing 
of taking drug according to lifestyle and further improvement of Quality Of Life(QOL) from less 
number of doses was in need. The phase III clinical study conducted at the development stage has 
shown that trelagliptin, when administered for 24 weeks, was not inferior to alogliptin, a DPP-4 
inhibitor used as control, in terms of the change in HbA1c at the end of the treatment period 10). 
However, effect on glycemic variation of trelagliptin and alogliptin has not been clarified efficiently, 
and it is anticipated that understanding the characteristics of once weekly DPP-4 inhibitors and once 
daily DPP-4 inhibitors may be an efficient rational for therapeutical use.

Because there is no enough evidence assayed for glycemic variation of not only once weekly DPP-4 
inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, and 
Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive data of 
glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhinitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period, the effect on glycemic variation of alogliptin have to be clarified when the effect of different 
dose and method of administraion of DPP-4 inhibitors on glycemic variation would like to be 
evaluated. 
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administraion on 
glycemic variation will be evaluated as secondary as far as possible.

6.2 
Rationale for the clinical research design 
(1) Rationale for the clinical research design 
  
Because there is no enough evidence assayed for glycemic variation of not only once weekly 
DPP-4 inhibitors but also once daily DPP-4 inhibitor, Trelagliptin, once weekly DPP-4 inhibitor, 
and Alogliptin, once daily DPP -4 inhibitor, were set as study drugs to collect the consecutive 
data of glycemic variation obtained from CGM and to evaluate difference of DPP-4 inhibitors.  
Although trelagliptin was non-inferior to alogliptin, once daily DPP-4 inhinitor, in terms of the 
change from baseline in HbA1c at the phase III clinical study conducted during the development 
period,  the effect on glycemic variation of alogliptin have to be clarified when the effect of 
different dose and method of administraion of DPP-4 inhibitors on glycemic variation would like 
to be evaluated.  
In this present study, therefore, the effect of once weekly trelagliptin or once daily alogliptin on 
glycemic variation will be evaluated in patients with type 2 diabetes mellitus in an exploratory 
manner as a primary objective, and the effect by difference of dose and method of administraion 
on glycemic variation will be evaluated as secondary as far as possible.

Therefore this unblind study was designed to objectively evaluate the effect on glycemic variation of 
trelagliptin 100 mg and alogliptin 25 mg administered in patients with type 2 diabetes mellitus. And 
also to evaluate the effect of different method of administraion on glycemic variation, stratified 
randomization comparison method between 2 groups was adopted with “HbA1c at the start of the 
observation period (< 7.5% or ≥ 7.5%) and age (< 65 or ≥ 65)” as a stratification factor for 
randomization. 
Also, to exclude effect on glycemic variation from other anti-diabetic medications, research 
subjects who were taking anti-diabetic medications ≤ 4 weeks before start of observation period 
were excluded. 
(2) Rationale for dosage 
The dosages of trelagliptin and alogliptin were set at 100 mg/week and 25 mg/day, respectively, 
to evaluate glycemic variation at the usual dosage in clinical settings.  
(3) Rationale for dosage 
Study drugs show the glucose lowering effect by increasing incretin which are secreted by food 
intake. Thus, in order to eliminate the influence on the blood glucose by food intake. To further 
unify the administration timing of the research subjects prior to breakfast in terms of evaluating 
their glycemic variation. 
(4) Rationale for duration of treatment 
From the results of trelagliptin and alogliptin in phase II and III trials, duration was set at 4 
weeks taking into account that the effect on blood glucose levels stabilize after 2 to 4 weeks 
with either drugs. 
(5) Rationale for the number of planned research subjects: 
Refer section 13.3

10.0 
ADVERSE EVENT 
10.1 
Definitions 
10.1.1 Adverse event 
An adverse event is defined as any untoward medical occurrence in a patient or a research subject 
receiving a pharmaceutical product (including the study drug). It does not necessarily have an 
apparent causal relationship with this pharmaceutical product (including study drug). 
An adverse event can therefore be any unfavorable or unintended sign (e.g., clinically significant 
laboratory abnormality), symptom, or disease temporally associated with the use of a pharmaceutical 
product (including the study drug), regardless of whether it is considered related to the 
pharmaceutical product (including the study drug) or not. 
10.1.2 Considerations for adverse events 
Generally unfavorable findings are described below: 
• 
Newly diagnosed disease or unexpected aggravation of existing symptom (intermittent 
event of an existing symptom is not considered an adverse event) 
• 
Requiring action or medical practice 
• 
Requiring invasive diagnostic treatment 
• 
Requiring discontinuation or a change in the dose of the study drug or a concomitant 
medication 
• 
Considered unfavorable by the principal investigator or the investigator 
Diagnosis name and signs/symptoms: 
Adverse events shall be recorded by diagnosis name. Accompanying signs (including abnormal 
laboratory values, abnormal ECG findings) and symptoms shall not be recorded as adverse events. If 
an adverse event could not be expressed by a diagnosis name, the signs or symptoms shall be 
recorded as the adverse event. 
Laboratory test values and ECG findings: 
Abnormal laboratory values and ECG findings shall be recorded as adverse events when the 
principal investigator or investigator judges the results are clinically problematic (in other words, 
when certain action or medical practice is required, or when the principal investigator or the 
investigator judges the change has exceeded the normal physiological variation range of the research 
subject). Retest and/or continued monitoring of an abnormality are not considered medical practice. 

122/NRP-001 
"Protocol No. Trelagliptin-4001"  
Page 43 of 72
Initial Version 
March 29, 2016
 
CONFIDENTIAL 
Also, repeated or additional conduction of non-invasive tests for verification, evaluation, and 
monitoring of an abnormality are not considered medical practice. 
However, when abnormal laboratory values and ECG findings are the accompanying symptoms of a 
disease diagnosed as an adverse event (e.g., increased creatinine due to renal dysfunction, etc.), the 
adverse event shall be handled by its diagnosis name. 
Pre-existing conditions (disease or symptom that has been present since before the start of study 
treatment): Pre-existing disease or symptom that has been present since before the start of study 
treatment shall be regarded as a concurrent disease and not an adverse event. When a concurrent 
medical condition is aggravated, the aggravation shall be determined as an adverse event and the 
principal investigator or the investigator shall record on the CRF that the adverse event is an 
aggravation of the concurrent disease (e.g., “aggravation of hypertension,” etc.). 
If a research subject has a pre-existing episodic condition (e.g., asthma, epilepsy), each episode shall 
be recorded as an adverse event if the episodes become more frequent, serious, or severe in nature. If 
a research subject has a chronic concurrent condition (e.g., cataracts, rheumatoid arthritis), 
worsening of the condition shall be recorded as adverse event if the degree of the worsening exceeds 
that which would be expected. The principal investigator or investigator shall ensure that the adverse 
event term to be recorded represents the change in the condition from baseline (e.g. “worsening 
of…”). 
Worsening of adverse events:  
If a research subject experiences a worsening of the adverse event after a change to the study drug, 
or secondary signs and symptoms are caused by the adverse event, the worsening or the secondary 
signs and symptoms shall be recorded as a new adverse event on the CRF. The principal investigator 
or investigator shall use an adverse event term that explicitly means a change of the condition (e.g., 
“worsening of…”). 
Change of severity of adverse events:  
If the research subject experiences changes in the severity of an adverse event, the event shall be 
recorded once, at its peak severity. 
Previously planned surgery or treatment:  
Preplanned surgeries or interventions that were scheduled before study treatment shall not be 
considered adverse events. However, when the existing symptom is aggravated to a degree requiring 
emergency surgery or treatment, the condition or the event shall be considered an adverse event. A 
concurrent disease that resulted from previously planned surgery shall be reported as an adverse 
event.

March 29, 2016
 
CONFIDENTIAL 
Non-urgent surgery or treatment:  
Non-urgent surgery or treatment that does not induce a change in the condition of a research subject 
(cosmetic surgery, etc.) shall not be considered an adverse event; However, it shall be recorded in 
the source documents. Concurrent diseases due to a non-urgent surgery shall be reported as an 
adverse event. 
The insufficient clinical response (lack of efficacy): insufficient clinical response, efficacy, or 
pharmacological action shall not be recorded as an adverse event. The principal investigator or 
investigator shall make the distinction between worsening of a pre-existing condition and lack of 
therapeutic efficacy. 
Overdose of the study drug:  
Overdose of any medication without onset of event shall not be recorded as an adverse event, but the 
overdose shall be recorded on the “Overdose” page of the CRF. Any onset of event shall be recorded 
as adverse events on the “Adverse events” of the CRF. 
10.1.3 Serious adverse event 
Of all unfavorable medical events that develop after administration of a pharmaceutical product 
(including the study drug) (irrespective of dose), a serious adverse event is an event that: 
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, or 
6. Medically important event that causes a risk to the research subject even if it is not 
immediately life-threatening and does not result in death or hospitalization, or requires an 
action or treatment to prevent the results described in 1 to 5 above. Points described in the 
Takeda Medically Significant Adverse Event List (Table 10.a) are included in this section. 
* The term “life threatening” refers to an event in which the research subject was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have caused death if it 
were more severe.

An AE of Special Interest (AESI) (serious or non-serious) is one of scientific and medical concern 
specific to the study drug, for which ongoing monitoring and rapid communication by the principal 
investigator or investigator to Takeda may be appropriate. Such events may require further 
investigation in order to establish assessment, and instructions provided to investigators on how and
