STUDY SUMMARY
Name of Sponsor(s):
Takeda Pharmaceuticals LLC
Compound:
SYR-322-4833
Title of Protocol: A Randomized, Open-Label, 
Single-Dose, 4-Period Crossover Study to Determine the 
Bioequivalence of Alogliptin (25 mg) and Pioglitazone (15 
and 30 mg) When Administered as Individual Tablets and 
as Fixed-Dose Combination Tablets to Healthy Russian 
Subjects
IND No.: 
Not applicable
EudraCT No.:
Not applicable
Study Number: Alogliptin-1002
Phase: Bioequivalence
Study Design:
This is a single-center randomized, open-label, 4-sequence, 4-period, single-dose, crossover study to assess the 
bioequivalence, pharmacokinetics (PK), and safety of alogliptin and pioglitazone administered as individual tablets 
and as the fixed-dose combination (FDC) tablet product. 
Subjects will be randomized in the order in which they are enrolled into the study. The 72 eligible subjects will be 
randomized to 1 of 4 drug intake sequences in a 1:1:1:1 ratio. Due to the large sample size, volunteers may be divided 
into 2 or 3 cohorts according to space limitations at the site. All cohorts will be dosed sequentially.
The study consists of a Screening Period (Days -28 to Day-2) and 4 Drug Intake Periods. A washout interval of 7 days 
(beginning immediately after dosing on Day 1) will separate the doses of each study period. Subjects will be admitted 
into the clinic on Day -1 (Day 7 of the preceding period for Periods 2, 3, and 4) and will be dosed on Day 1 of each 
period. Starting on Day 1 of each period, blood samples for determination of alogliptin and pioglitazone plasma 
concentrations will be collected predose through 72 hours postdose. The subjects will be discharged from the clinic 
after the 24-hour blood sample collection on Day 2 of each period and will return to the clinic for the 36-hour blood 
sample collection on Day 2 and on Days 3 and 4 of each period to complete study procedures. Final Visit procedures 
will be performed on Day 4 of Period 4 and a Follow-up call will be made 14 days ±2 days following the last dose of 
study drug.
Primary Objective:
To assess the relative bioavailability and bioequivalence of 2 strengths of the fixed-dose combination tablet product 
SYR-322-4833 BL compared to the individual alogliptin and pioglitazone tablets in healthy Russian subjects.
Additional Objectives:
To perform a comparative analysis of adverse event (AE) data after the administration of SYR-322-4833 BL and after 
coadministration of alogliptin and pioglitazone to healthy volunteers within the scope of the trial.
Subject Population: Healthy subjects aged 18 to 55 years, inclusive.
Number of Subjects:
Approximately 144 subjects will be screened. 
72 subjects (18 per sequence) will be enrolled.
Number of Sites:
1 site in Russia
Dose Level(s):
A= SYR-322-4833 BL (25 mg + 15 mg) (test regimen)
B= alogliptin 25 mg + pioglitazone 15 mg (reference regimen)
C= SYR-322-4833 BL (25 mg + 30 mg) (test regimen)
D= alogliptin 25 mg + pioglitazone 30 mg (reference regimen)
Route of Administration:
Oral
Duration of Treatment:
4 single doses, 1 dose in each of 4 periods
Period of Evaluation:
Total study duration: approximately 66 days 
(including Screening Period, Drug Intake Period, 
and Follow-up telephone call).

Statistical Considerations:
Descriptive statistics (N, mean, SD, SE, percent coefficient of variation [%CV], median, minimum, and maximum) 
will be used to summarize the PK parameters of alogliptin and pioglitazone for each regimen. Geometric means will 
be computed for AUCs and Cmax.
Statistical inference to determine if the test regimens are bioequivalent to the reference regimens will be performed 
using an analysis of variance (ANOVA) model with effects for regimen, period, sequence, and subjects nested within 
sequence. The effect due to subject nested within sequence will be considered a random effect in the ANOVA model 
while all other effects will be treated as fixed. The ANOVA model will be applied to the natural logarithms of AUC72
and Cmax of alogliptin or pioglitazone as dependent variables to compare the test and reference regimens. Within the 
framework of the ANOVA model for natural logarithms of AUC72 and Cmax, the ratios and the 90% confidence 
intervals (CIs) for the ratios of central values of each test regimen relative to the corresponding reference regimen of 
alogliptin or pioglitazone will be provided. The ratios will be obtained as the antilog of the difference of the least 
squares (LS) means on a natural logarithm scale, and the 90% CIs will be obtained by taking the antilog of the 90% CI 
for the difference between the LS means on the natural logarithmic scale.
Alternative statistical analyses will be used if deemed appropriate.
All subject condition assessments, including AEs, physical examinations, clinical laboratory evaluations, 12-lead 
ECGs, and vital signs will be presented in the data listings and summarized with descriptive statistics, if appropriate.
Sample Size Justification: A sample size of 72 subjects (18 per sequence) will be enrolled in this 4-period, 
4-sequence crossover study. The sample size is appropriate to assess the bioavailability of alogliptin and pioglitazone 
from the FDC relative to the individual tablets and also provide greater than 80% power for Cmax of pioglitazone 
establishing bioequivalence between regimens for both strengths (SYR-322-4833 BL 25 mg+15 mg and 
SYR-322-4833 BL 25 mg+30 mg). This is based on acceptance ranges of 80% to 125%, the intra-subject variability 
(%CV) of 33% for Cmax of pioglitazone; the expected ratios of the central values for Cmax are between 0.95 and 1.05, 
and drop-out rate of 14%. Since the intra-subject variability for pioglitazone area under the concentration-time curve 
from time 0 to time t (AUCt), and alogliptin Cmax and AUCt is less than 33%, the power for assessing bioequivalence 
for pioglitazone AUCt and alogliptin Cmax and AUCt are each greater than 80% for both strengths.

INTRODUCTION
4.1
Background
4.1.1
Alogliptin
Alogliptin is an orally available, selective and highly potent inhibitor of dipeptidyl peptidase-4 
(DPP-4), the primary enzyme involved in the in vivo degradation of at least 2 incretin hormones 
released in response to nutrient ingestion: glucagon-like peptide-1 (GLP-1) and glucose-dependent 
insulinotropic polypeptide (GIP). The incretin hormones exert important effects on pancreatic islet 
-cells to stimulate glucose-dependent insulin secretion and regulate -cell proliferation and 
cytoprotection. By preventing the rapid degradation of these hormones, alogliptin enhances the 
body’s ability to control elevated blood glucose by triggering pancreatic insulin secretion and 
suppressing pancreatic glucagon secretion, resulting in reductions in glycemia. 
Alogliptin has been approved as an adjunct to diet and exercise to improve glycemic control in 
patients with type 2 diabetes mellitus (T2DM). Alogliptin has been commercially available since 
2010 and is approved in several major markets including Japan, the United States (US), the 
European Union (EU), and Russia.
4.1.2
Pioglitazone
Pioglitazone is an insulin sensitivity enhancer, which decreases insulin resistance by binding to 
peroxisome proliferator-activated receptor-gamma (PPAR-γ). Pioglitazone depends on the 
presence of insulin for its mechanism of action. It decreases insulin resistance in the periphery and 
in the liver, resulting in increased insulin-dependent glucose disposal and decreased hepatic 
glucose output. Pioglitazone is a potent and highly selective agonist for PPAR-γ. Activation of 
PPAR-γ leads to increased insulin-mediated glucose uptake in skeletal muscle [1], decreased 
hepatic glucose production, reduced lipolysis, enhanced adipose differentiation [2], improved 
fibrinolysis, decreased microalbuminuria [3], and improved inflammatory markers, such as 
C-reactive protein [4].
Pioglitazone has been commercially available since 1999 and is approved in several major markets 
including the United States, Japan, and the European Union as an adjunct to diet and exercise to 
improve glycemic control in adults with T2DM in multiple clinical settings. 
Pioglitazone is a thiazolidinedione (TZD) that depends on the presence of insulin for its 
mechanism of action. Pioglitazone decreases insulin resistance in the periphery and in the liver 
resulting in increased insulin-dependent glucose disposal and decreased hepatic glucose output. 
Pioglitazone is not an insulin secretagogue. Pioglitazone is an agonist for PPARγ. PPAR receptors 
are found in tissues important for insulin action such as adipose tissue, skeletal muscle, and liver. 
Activation of PPARγ nuclear receptors modulates the transcription of a number of insulin 
responsive genes involved in the control of glucose and lipid metabolism.
Treatment with pioglitazone as monotherapy or in combination with metformin, a sulfonylurea, or 
insulin results in improvements in glycosylated hemoglobin (HbA1c) and fasting plasma glucose 
(FPG). Pioglitazone also appears to preserve β-cell function, which may explain its

antihyperglycemic durability [5]. Pioglitazone has favorable effects on lipids, including increasing 
high-density lipoprotein (HDL) cholesterol, decreasing triglycerides, and shifting low-density 
lipoprotein (LDL) particle size and concentration to a less atherogenic profile [6]. Pioglitazone 
treatment has also been associated with improvements in several other cardiovascular risk factors, 
such as markers of vascular effects (eg, reduced blood pressure, reduced smooth muscle 
proliferation, improved endothelial function, reduced microalbuminuria, and increased nitric 
oxide levels), anti-inflammatory effects (eg, decreased C-reactive protein levels, decreased 
interleukin-6 levels), and antithrombotic effects (eg, decreased plasminogen activator inhibitor-1 
levels) [7,8]. 
4.1.3
SYR-322-4833 BL
SYR-322-4833 BL is an oral, immediate-release, alogliptin fixed-dose combination (FDC) 
product with pioglitazone developed by Takeda as an adjunct to diet and exercise to improve 
glycemic control in patients with T2DM. Alogliptin FDC with pioglitazone has also been 
approved in several major markets including United States and European Union. 
4.2
Summary of Relevant Clinical Studies
4.2.1
Summary of Clinical Studies With Alogliptin
Alogliptin has been evaluated in 59 completed clinical studies (31 phase 1, 1 phase 2, and 27 phase 
3 studies) in both healthy subjects and subjects with T2DM, as part of the alogliptin clinical 
program. Alogliptin doses ranged from 6.25 to 800 mg in the clinical pharmacology studies, and 
from 6.25 to 100 mg in the phase 2 efficacy and safety study. Alogliptin doses of 12.5 and 25 mg 
were used in the pivotal phase 3 studies.
Results from 5 main, pivotal phase 3 double-blinded placebo-controlled studies (monotherapy and 
add-on to a sulfonylurea, metformin, TZD, and insulin) indicated that subjects with T2DM who 
were treated with alogliptin 12.5 or 25 mg once daily (QD) for 26 weeks achieved significantly 
greater least squares (LS) mean reductions in HbA1c levels versus those who received placebo.
Both doses of alogliptin evaluated in the phase 3 clinical program (12.5 and 25 mg QD) had an 
acceptable safety profile whether administered as monotherapy or in combination to other 
established antidiabetic therapies. Alogliptin was generally hypoglycemia and weight neutral. The 
following adverse drug reactions were associated with alogliptin in the clinical program: 
headache, upper respiratory tract infection, nasopharyngitis, abdominal pain, gastroesophageal 
reflux disease, pruritus, and rash. In addition, the following post-marketing adverse drug reactions 
have been spontaneously reported: acute pancreatitis, hepatic dysfunction including hepatic 
failure, hypersensitivity, and exfoliative skin conditions including Stevens-Johnson syndrome, 
erythema multiforme, angioedema, and urticaria.

4.2.2
Summary of Clinical Studies With Pioglitazone
The clinical trial database for pioglitazone consists of 47 studies (36 controlled, 11 uncontrolled) 
in a total of >27,000 treated subjects. These studies include 12 long-term controlled trials, ≥1 year 
in duration. Across these studies, the efficacy of pioglitazone has been evaluated in terms of 
glycemic control, lipid metabolism, and cardiovascular effects. 
Pioglitazone 7.5 to 45 mg daily has been compared with placebo in several randomized, double 
blind, parallel-group studies in patients with T2DM. Pioglitazone 15, 30, and 45 mg produced 
significant improvements in HbA1c (–0.3% to –1.8% and up to –2.6%, respectively) and FPG. 
Pioglitazone also produced significant decreases in triglycerides and significant increases in high 
density lipoprotein [9].
In combination trials with metformin, patients poorly controlled with a sulfonylurea (SU) were 
randomly assigned to metformin or pioglitazone, with comparable improvements seen in both 
compounds with respect to HbA1c and FPG [9]. In a combination trial, metformin plus 
pioglitazone 30 mg was compared with metformin plus placebo in patients with poorly controlled 
T2DM. Treatment with pioglitazone 30 mg plus metformin resulted in significant improvements 
in HbA1c, FPG, and lipid profiles compared with placebo plus metformin. [9,10]. In 2 
active-comparator trials, treatment with metformin and pioglitazone resulted in equal, significant 
reduction in HbA1c while insulin sensitivity measured by homeostasis model assessment showed 
significant improvement in the pioglitazone, but not the metformin group at 32 weeks [9].
In comparative/combination trials with SUs, pioglitazone produced comparable reduction in 
HbA1c and FPG as SU. Pioglitazone produced a slower but more sustained reduction in HbA1c 
compared with an earlier effect in the SU treated group, and improvements in insulin sensitivity 
were not seen in the SU treatment group [9]. Similar to results observed in combination trials with 
metformin, pioglitazone-treated subjects demonstrated significant improvements in glycemic 
control and lipid profiles compared with treatment with SU [9]. 
4.2.3
Summary of Clinical Studies With Alogliptin in Combination With Pioglitazone
The coadministration of alogliptin and pioglitazone has been studied in subjects with T2DM 
inadequately controlled on either diet and exercise alone, pioglitazone alone, or pioglitazone in 
combination with metformin. 
There have been no completed clinical efficacy studies conducted with alogliptin/ pioglitazone 
FDC; however, bioequivalence of alogliptin/ pioglitazone FDC with coadministered alogliptin and 
pioglitazone tablets was demonstrated, and efficacy of the combination of alogliptin and 
pioglitazone has been demonstrated in 4 phase 3 efficacy studies. 
Results from 4 phase 3 double-blinded placebo or active-controlled clinical safety and efficacy 
studies ranging from 16 to 52 weeks indicated that subjects with T2DM who were treated with 
alogliptin (12.5 mg or 25 mg) and pioglitazone (15, 30, or 45 mg) combination therapy achieved 
significantly greater LS mean reductions in HbA1c compared to placebo and each individual 
monotherapy.

All dose combinations studied in the alogliptin/pioglitazone FDC program were well tolerated. 
The majority of subjects completed the studies, and the overall discontinuation rate due to adverse 
events (AEs) was low. The safety profile of combination treatment was consistent with the known 
safety profiles of pioglitazone and alogliptin.
The following adverse drug reactions were associated with alogliptin and pioglitazone 
combination therapy in the clinical program: upper respiratory tract infection, sinusitis, headache, 
nausea, dyspepsia, abdominal pain, pruritus, myalgia, edema peripheral, and weight increased. 
See the investigator brochure for detailed information about alogliptin/pioglitazone combination 
clinical studies.
4.3
Benefit/Risk Profile 
Data from the clinical studies have demonstrated that the coadministration of alogliptin and 
pioglitazone results in improved glycemic control. In these studies, combination therapy with 
alogliptin with pioglitazone resulted in greater clinically meaningful reductions in HbA1c than 
with either agent given alone. This greater reduction in HbA1c resulted in a higher percentage of 
subjects who achieved the HbA1c goal of ≤7%. An additional glycemic benefit of combination 
therapy was a reduction in FPG levels without a corresponding increase in risk of hypoglycemia, 
an AE that often restricts use with other antidiabetic agents. 
Another goal of T2DM treatment is to reduce cardiovascular risk factors such as dyslipidemia and 
elevated inflammatory markers, which are common in patients with T2DM. Combination therapy 
of pioglitazone and alogliptin enhanced the pioglitazone effects of reduced triglycerides, increased 
HDL, decreased LDL, improved LDL particle size, and decreased C-reactive protein levels. 
Some risks that have been identified with the use of pioglitazone or other TZDs are congestive 
heart failure, edema, bladder cancer, hepatic effects, hematological effects, hypoglycemia (when 
used with other antihyperglycemic medicinal products), bone fractures, and macular edema. Risks 
that have been identified with the use of alogliptin or other DPP-4 inhibitors are hypoglycemia 
(when used with other antihyperglycemic medicinal products), cardiac failure, hypersensitivity 
reactions, acute pancreatitis, and hepatic effects.
The alogliptin/ pioglitazone FDC will provide flexibility in reaching efficacy goals without 
compromising safety, thereby allowing prescribers to individualize therapy. In addition, it is 
generally accepted that the convenience of an FDC product provides significant improvement with 
respect to compliance and alleviation of pill burden in patients with chronic illnesses such as 
T2DM [11-13]. Based on the efficacy and safety data, the benefit:risk ratio is favorable for the use 
of alogliptin/ pioglitazone FDC to improve glycemic control in adults with T2DM. 
4.4
Rationale for the Proposed Study
Takeda has developed an FDC product with alogliptin and pioglitazone (SYR-322-4833 BL). 
Alogliptin and pioglitazone potentially have complimentary mechanisms of action and could 
potentially be prescribed in combination. An FDC product may provide improve convenience for 
the patient, and therefore, may improve compliance.

The bioequivalence of alogliptin/pioglitazone FDC with co-administration of alogliptin and 
pioglitazone tablets has been established in the US and EU population. However, this 
bioequivalence has not been demonstrated specifically in the Russian population. In order to better 
bridge the alogliptin and pioglitazone combination therapy clinical data to the Russian population 
and meet local regulatory requirements for further alogliptin/pioglitazone FDC registration in 
Russia, this study is designed to determine whether peak and total exposures to alogliptin and to 
pioglitazone are bioequivalent when the 2 agents are administered as an FDC product and as 
individual tablets in Russian subjects.

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is a single-center, open-label, randomized, 4-sequence, 4-period, single dose crossover study 
involving 72 healthy adult, male and female subjects between the ages of 18 and 55 years, 
inclusive. 
Subjects will be randomized in the order in which they are enrolled into the study. The 72 eligible 
subjects will be randomized to 1 of 4 drug intake sequences in a 1:1:1:1 ratio. Due to the large 
sample size, volunteers may be divided into 2 or 3 cohorts according to space limitations at the 
site. All cohorts will be dosed sequentially.
The study consists of a Screening Period (Days -28 to Day-2) and 4 Drug Intake Periods. A 
washout interval of 7 days (beginning immediately after dosing on Day 1) will separate the doses 
of each study period. Subjects will be admitted into the clinic on Day -1 (Day 7 of the preceding 
period for Periods 2, 3, and 4) and will be dosed on Day 1 of each period. Starting on Day 1 of each 
period, blood samples for determination of alogliptin and pioglitazone plasma concentrations will 
be collected predose through 72 hours postdose. The subjects will be discharged from the clinic 
after the 24-hour blood sample collection on Day 2 of each period and will return to the clinic for 
the 36-hour blood sample collection on Day 2 and on Days 3 and 4 of each period to complete 
study procedures. Final Visit procedures will be performed on Day 4 of Period 4 and a Follow-up 
call will be made 14 days ±2 days following the last dose of study drug.
A schematic of the study design is included as Figure 6.a. A schedule of assessments is listed in 
Appendix A.

(c) Randomization occurs on Day 1 of Period 1. Subjects check out of the unit on Day 2 following the 24-hour blood sample 
collection but return to the clinic for the 36-hour blood sample collection on Day 2 and on Days 3 and 4 of each period to complete 
study procedures.
(d) Follow-up call will be made 14 days ±2 days following the last dose of study drug.
6.2
Justification for Study Design, Dose, and Endpoints
The dose of alogliptin selected for this study (25 mg) is the approved daily dose, which was 
efficacious and well-tolerated in the monotherapy program. The doses of pioglitazone (15 and 
30 mg) chosen for this study are approved therapeutic doses.
A randomization schedule for dose administration assignment will be used to reduce the potential 
for bias. A crossover design will be used to allow for intrasubject comparisons. To minimize the 
potential for carryover effect, a 7-day washout interval, which is >5 half-lives of either alogliptin 
or pioglitazone, will separate the dose administrations.
Single doses will be administered because single doses generally allow for a more sensitive 
assessment of the release of the drug substance from the drug product into the systemic circulation. 
Only parent drug released from the dosage form, rather than metabolites, will be measured, 
because the concentration-time profile of the parent drug is more sensitive to changes in 
formulation performance than a metabolite. 
The safety endpoints in this study, including AEs, vital signs, 12-lead ECGs, clinical laboratory 
tests and physical examination data, are standard methods for assessing safety and tolerability in 
clinical pharmacology studies.
This study is being conducted for the purpose of registration of SYR-322-4833 BL by the Russian 
Ministry of Health.

Diet, Fluid, Activity Control 
Subjects will be confined to the clinic from Check-in (Day -1) of Dosing Period 1 until the 24-hour 
blood sample has been collected on Day 2 of Dosing Period 1 and from Day 7 of Dosing Periods 1, 
2, and 3 until the 24-hour blood sample has been collected on Day 2 of Dosing Periods 2, 3, and 4, 
respectively. During confinement, subjects will be given a menu that includes 3 meals and an 
evening snack, except dosing days when breakfast will not be served. Study drug will be 
administered with 240 mL of water. Subjects may consume water ad libitum with the exception of 
1 hour before and 1 hour after drug administration. On Day 1 of each period, all subjects will 
remain fasted until a standard lunch is served approximately 4 hours postdose (after the 4-hour 
blood collection). Each meal will contain approximately 30% fat (relative to the total calories). 
The meals served in each period should be identical. Each meal provided in the study clinic should 
be completed within 30 minutes. The meal start and stop times and whether or not a meal was 
consumed will be recorded on the source documentation and the electronic case report form 
(eCRF) for the Day-1 snack and all meals on Day 1 of each period. The study menu should be

documented and submitted to the study file with a copy provided to the sponsor prior to the start of
the study.
If a blood draw or any study procedure coincides with a meal, the blood draw will take precedence 
followed by the study procedure and then the meal. Subjects will remain upright (seated, standing, 
or ambulatory) for at least 2 hours following administration of study medication, except as 
necessitated by the occurrence of an adverse event. Subjects will refrain from strenuous exercise 
throughout the entire course of the study.
7.5
Criteria for Discontinuation or Withdrawal of a Subject
The primary reason for discontinuation or withdrawal of the subject from the study or study drug 
should be recorded in the eCRF using the following categories. For screen failure subjects, refer to 
Section 9.1.14.
1. AE. The subject has experienced an 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 AE.
2. Significant protocol deviation. The discovery post-randomization that the subject failed to 
meet protocol entry criteria or did not adhere to protocol requirements, and continued 
participation poses an unacceptable risk to the subject’s health.
3. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. Attempts to contact the subject must be documented in the subject’s source 
documentation.
4. Voluntary withdrawal. The subject wishes to withdraw from the study. The reason for 
withdrawal, if provided, should be recorded in the eCRF.
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (ie, withdrawal due to an
AE should not be recorded in the “voluntary withdrawal” category).
5. Study termination. The sponsor, IRB, IEC, or regulatory agency terminates the study.
6. Pregnancy. The subject is found to be pregnant. 
Note: If the subject is found to be pregnant, the subject must be withdrawn immediately. The 
procedure is described in Section 9.1.10.
7. Other.
Note: The specific reasons should be recorded in the “specify” field of the eCRF.
7.6
Procedures for Discontinuation or Withdrawal of a Subject
The investigator may discontinue a subject’s study participation at any time during the study when 
the subject meets the study termination criteria described in Section 7.5. In addition, a subject may 
discontinue his or her participation without giving a reason at any time during the study. Should a
subject’s participation be discontinued, the primary criterion for termination must be recorded by

Investigational drug must be kept in an appropriate, limited-access, secure place until it is used or 
returned to the sponsor or designee for destruction. Investigational drug, must be stored under the 
conditions specified on the label, and remain in the original container until dispensed. A daily 
temperature log of the drug storage area must be maintained every working day.
Drug supplies must be stored, as defined on the commercial packs provided, in a secure location 
until dispensed to study subjects or returned to Takeda. Temperature excursions must be reported 
to the sponsor. In order to protect drug supply from moisture, the container should be kept tightly 
closed (bottle) or stored in the original package (blister). Do not take a tablet out of the blister foil 
until the subject is ready to take it.
8.1.3
Dose and Regimen
On Day 1 of each period, study medication will be administered at 08:00 (±1) hour with 240 mL of 
water following a minimum 8-hour fast. On Day 1 of each period, all subjects will remain fasted 
until a standard lunch is served approximately 4 hours postdose (after the 4-hour blood collection). 
The sequence of drug intake administration for each subject as described in Table 8.a will follow 
the randomization schedule. The investigator or investigator’s designee will instruct the subject on 
dosing procedures.
Following administration of study drug, hand-and-mouth checks will be performed to ensure that 
the dose was swallowed and will be recorded on the source document. Although timing of events 
requires that each subject receive the appropriate dose at specific times, the exact dose time of 
consecutive subjects may be staggered to obviate the need to have all subjects on precisely the 
same study schedule. The actual date and time of administration of the dose of study medication 
will be recorded on the source documents and the appropriate eCRF.

Overdose
An overdose is defined as a known deliberate or accidental administration of study drug, to or by a 
study subject, at a dose above that which is assigned to that individual subject according to the 
study protocol.
All cases of overdose (with or without associated AEs) will be documented on an Overdose page 
of the eCRF, in order to capture this important safety information consistently in the database. 
Cases of overdose without manifested signs or symptoms are not considered AEs. AEs associated 
with an overdose will be documented on AE CRF(s) according to Section 10.0.
Serious adverse events (SAEs) associated with overdose should be reported according to the 
procedure outlined in Section 10.2.2.
In the event of drug overdose, the subject should be treated symptomatically.
8.2
Study Drug Assignment and Dispensing Procedures
Subjects will be assigned to receive a 4-digit medication identification number. The number will 
be assigned by the clinic site personnel in sequential order beginning with 1001 and ending with 
1072. This 4-digit number will be used by the clinical site to facilitate the prelabeling of PK 
samples, and will be the only subject identifier used on all PK sample collections. It should also be 
contained on the PK transport vials shipped to the bioanalytical laboratory, and will be used by the 
laboratory to report the subject data results. This 4-digit number should only be used for the 
purposes described in this section. It does not replace the 3-digit subject number which is assigned 
at the time the informed consent is obtained and which is used for all other procedures to identify 
the subjects throughout the study.

8.3
Randomization Code Creation and Storage
The randomization schedule will be generated prior to the start of the study, and will be provided 
to the site pharmacist prior to the start of this study. All randomization information will be stored 
in a secured area, accessible only by authorized personnel.
8.4
Accountability and Destruction of Sponsor-Supplied Drugs
Drug supplies will be counted and reconciled at the site before being returned to the sponsor or 
designee.
The investigator or designee must ensure that the sponsor-supplied drug is used in accordance with 
the protocol and is dispensed only to subjects enrolled in the study. To document appropriate use 
of sponsor-supplied drug, the investigator or designee must maintain records of all 
sponsor-supplied drug delivery to the site, site inventory, dispensation and use by each subject, and 
return to the sponsor or designee.
Upon receipt of sponsor-supplied drug, the investigator or designee must verify the contents of the 
shipments against the packing list. The verifier should ensure that the quantity is correct, and the 
medication is in good condition. If quantity and conditions are acceptable, investigator or designee 
should acknowledge the receipt of the shipment by signing bottom half of the packing list and 
faxing per instructions provided on the form. If there are any discrepancies between the packing 
list versus the actual product received, Takeda must be contacted to resolve the issue. The packing 
list should be filed in the investigator’s essential document file.
The investigator or designee must maintain 100% accountability for all sponsor-supplied drugs 
received and dispensed during his or her entire participation in the study. Proper drug 
accountability includes, but is not limited to:

Continuously monitoring expiration dates if expiration date is provided to the investigator or 
designee. 

Frequently verifying that actual inventory matches documented inventory.

Verifying that the log is completed for the drug lot used to prepare each dose.

Verifying that all containers used are documented accurately on the log.

Verifying that required fields are completed accurately and legibly.
If any dispensing errors or discrepancies are discovered, the sponsor must be notified immediately.
The investigator or designee must record the current inventory of all sponsor-supplied drugs on a 
sponsor-approved drug accountability log. The following information will be recorded at a 
minimum: protocol number and title, name of investigator, site identifier and number, description 
of sponsor-supplied drugs, expiry/retest date, date and amount dispensed, including initials, seal, 
or signature of the person dispensing the drug, and the date and amount returned to the site by the 
subject, including the initials, seal, or signature of the person receiving the sponsor-supplied drug. 
The log should include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.

Prior to site closure or at appropriate intervals, a representative from the sponsor or its designee 
will perform sponsor-supplied drug accountability and reconciliation before sponsor-supplied 
drugs are returned to the sponsor or its designee for destruction. The investigator or designee will 
retain a copy of the documentation regarding sponsor-supplied drug accountability, return, and/or 
destruction, and originals will be sent to the sponsor or designee.
The investigator will be notified of any expiry date or retest date extension of sponsor-supplied 
drug during the study conduct. On expiry date notification from the sponsor or designee, the site 
must complete all instructions outlined in the notification, including segregation of expired 
sponsor-supplied drug for return to the sponsor or its designee for destruction.

STUDY PLAN
9.1
Study Procedures
The following sections describe the study procedures and data to be collected. For each procedure, 
subjects are to be assessed by the same investigator or site personnel whenever possible. The 
Schedule of Study Procedures is located in Appendix A.
9.1.1
Informed Consent Procedure
The requirements of the informed consent are described in Section 15.2.
Informed consent must be obtained prior to the subject entering into the study, and before any 
protocol-directed procedures are performed, including requesting that a subject fast for laboratory 
evaluations.
A unique subject identification number (subject number) will be assigned to each subject at the 
time that informed consent is obtained; this subject number will be used throughout the study.
9.1.2
Demographics, Medical History, and Medication History Procedure
Demographic information to be obtained will include date of birth, sex, race as described by the 
subject, height, weight, caffeine consumption, xanthine consumption, alcohol use, reproductive 
status (including last menstrual period) and smoking status of the subject at Screening. 
Medical history to be obtained will include determining whether the subject has any significant 
conditions that resolved at or prior to signing of informed consent. Ongoing conditions are 
considered concurrent medical conditions (see Section 9.1.7).
Medication history information to be obtained includes any medication relevant to eligibility 
criteria stopped at or within 28 days prior to signing of informed consent.
9.1.3
Physical Examination Procedure
A baseline physical examination (defined as the assessment prior to first dose of study drug) will 
consist of the following body systems: (1) eyes; (2) ears, nose, throat; (3) cardiovascular system; 
(4) respiratory system; (5) gastrointestinal system; (6) dermatologic system; (7) extremities; (8) 
musculoskeletal system; (9) nervous system; (10) lymph nodes; and (11) other.
Any abnormal finding on a predose physical examination assessment must be assessed as not 
clinically significant (NCS) or clinically significant (CS) by the investigator and recorded in the 
source document and eCRF. All CS findings/changes will be recorded as a predose event or 
concurrent medical condition in the source document and on the appropriate eCRF described in 
Section 10.0 or Section 9.1.7. Any abnormal findings at Screening or prior to first dose, will 
exclude the subject from participating.
On subsequent examinations, any abnormal change or new diagnosis as a result of the abnormal 
change, compared to physical examination prior to first dose, as determined by the investigator, 
will be recorded as an AE in source documentation and on the AE eCRF described in Section 10.0.

9.1.4
Weight, Height and BMI
A subject should have weight and height measured while wearing indoor clothing and with shoes 
off. The BMI is calculated using metric units with the formula provided below. Height is recorded 
in centimeters without decimal places. Weight is collected in kilograms (kg) with 1 decimal place. 
BMI should be derived as:
Metric:
BMI = weight (kg)/height (m)2
Note that although height is reported in centimeters, the formula uses meters for height; meters can
be determined from centimeters by dividing by 100. Thus, for example, if height=176 cm 
(1.76 meters) and weight=79.2 kg, then BMI=79.2/1.762=25.56818 kg/m2.
The values should be reported to 1 decimal place by rounding. Thus, in the above example BMI 
would be reported as 25.6 kg/m2. If the BMI is used as an entry criterion based on the 18.5 to 
30.0 kg/m2 cut-off point, then this determination must be made after rounding.
9.1.5
Vital Sign Procedure
Vital signs will include body temperature oral measurement, respiratory rate, sitting blood 
pressure (resting at least 5 minutes), and pulse (bpm).
When vital signs are scheduled at the same time as blood draws, the blood draw will take priority 
and vital signs will be obtained within 0.5 hour before or after the scheduled blood draw. 
9.1.6
Documentation of Concomitant Medications
Concomitant medication is any drug given in addition to the study medication. These may be 
prescribed by a physician or obtained by the subject over the counter. Concomitant medication is 
not provided by Takeda. At each study visit, subjects will be asked whether they have taken any 
medication other than the study medication (used from signing of informed consent through the 
end of the study), and all medication including vitamin supplements, over-the-counter 
medications, and oral herbal preparations, must be recorded in the eCRF. Administration of any 
concomitant medications will result in exclusion of the subject from the trial. Documentation will 
include generic medication name, dose, unit, frequency, route of administration, start and end 
dates, and reason for use. 
9.1.7
Documentation of Concurrent Medical Conditions
Any abnormal medical conditions, abnormalities in laboratory, ECG or physical examination 
findings found at Screening will exclude the subject from participating in this clinical trial. 
9.1.8
Procedures for Clinical Laboratory Samples
All samples will be collected in accordance with acceptable laboratory procedures. Laboratory 
samples will be taken following a minimum 8-hour overnight fast on the days stipulated in the 
Schedule of Study Procedures (Appendix A).
Table 9.a lists the tests that will be obtained for each laboratory specimen.

The local laboratory will perform laboratory tests for hematology, serum chemistries, and 
urinalysis. The results of laboratory tests will be returned to the investigator, who is responsible for 
reviewing and filing these results.
If subjects experience ALT or AST >3 ×upper limit of normal (ULN), follow-up laboratory tests 
(at a minimum, serum alkaline phosphatase, ALT, AST, total bilirubin, GGT, and international 
normalized ratio [INR]) should be performed within a maximum of 7 days and preferably within 
48 to 72 hours after the abnormality was noted. (Refer to Section 10.2.3 for the appropriate 
guidance on reporting abnormal liver function tests.)
If the ALT or AST remains elevated >3 ×ULN on these 2 consecutive occasions, the investigator 
must contact the Medical Monitor for consideration of additional testing, close monitoring, 
possible discontinuation of study drug, discussion of the relevant subject details and possible

alternative etiologies. The abnormality should be recorded as an AE (please refer to Section 10.2.3
for reporting requirements).
The investigator will maintain a copy of the laboratory accreditation and the reference ranges for 
the laboratory used.
Laboratory reports must be signed and dated by the investigator indicating that the report has been 
reviewed and any abnormalities have been assessed for clinical significance. 
All laboratory abnormalities must be recorded as an AE in the subject’s source documents and on 
the appropriate eCRF. A clinically significant laboratory abnormality that has been verified by 
retesting will be followed until the abnormality returns to an acceptable level or a satisfactory 
explanation has been obtained.
9.1.9
Contraception and Pregnancy Avoidance Procedure
From signing of informed consent, throughout the duration of the study, and for 35 days after last 
dose of study medication, female subjects of childbearing potential* who are sexually active with a 
nonsterilized male partner** must use an effective or highly effective method of contraception 
from the list below. 
In addition, they must be advised not to donate ova during this period.
The following definitions apply for contraception and pregnancy avoidance procedures.
* A woman is considered a woman of childbearing potential, ie, fertile, following menarche and 
until becoming postmenopausal unless permanently sterile. Permanent sterilization methods 
include hysterectomy, and bilateral oophorectomy. A postmenopausal state is defined as no 
menses for 12 months without an alternative medical cause. A high follicle stimulating hormone 
(FSH) level in the postmenopausal range (FSH >40 IU/L) may be used to confirm a 
postmenopausal state in younger women (eg, those <45 years old) or women who are not using 
hormonal contraception or hormonal replacement therapy. However, in the absence of 12 months 
of amenorrhea, a single FSH measurement is insufficient.
** Sterilized males should be at least 1 year post-bilateral vasectomy and have confirmed that they 
have obtained documentation of the absence of sperm in the ejaculate or have had bilateral 
orchidectomy.
Highly effective methods of contraception are defined as those, alone or in combination, that result 
in a low failure rate (ie, less than a 1% failure rate per year when used consistently and correctly). 
In this study, where medications and devices containing hormones are excluded, highly effective 
methods of contraception are: 
Non-Hormonal Methods

Copper T PLUS condom or spermicide.

Bilateral Tubal Occlusion.

Barrier methods:

Double-barrier method (contraceptive sponge, diaphragm or cervical cap with spermicidal 
jellies or creams PLUS male condom).
Female subjects must discontinue any use of hormonal contraceptives (if applicable), at least 
2 months before the start (Day-1) of the trial.
Subjects will be provided with information on effective and highly effective 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 and donation of ova 
during the course of the study.
During the course of the study, regular urine human chorionic gonadotropin (hCG) pregnancy tests 
will be performed only for women of childbearing potential and subjects will receive continued 
guidance with respect to the avoidance of pregnancy as part of the study procedures (Appendix A). 
In addition to a negative urine hCG pregnancy test at Screening, subjects also must have a negative 
urine hCG pregnancy test at Check-in (Day-1 of each Period) prior to receiving any dose of study 
medication.
9.1.10 Pregnancy
If any subject is found to be pregnant during the study, she should be withdrawn and any 
sponsor-supplied drug should be immediately discontinued. In addition, any pregnancies in the 
partner of a male subject during the study or for 35 days after the last dose should also be recorded 
following authorization from the subject’s partner. 
If the pregnancy occurs during administration of active study medication, or within 35 days of the 
last dose of active study medication, the pregnancy should be reported immediately, using a 
pregnancy notification form, to the contact listed in Section 1.0.
If the subject and/or female partner of a male subject agree to the primary care physician being 
informed, the investigator should notify the primary care physician that the subject or female 
partner of the subject was participating in a clinical study at the time she became pregnant and 
provide details of the dose that the subject received.
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 Documentation of Randomization
Only subjects who meet all of the inclusion criteria and none of the exclusion criteria are eligible 
for randomization into the dosing phase.
If the subject is found to be not eligible for randomization, the investigator should record the 
primary reason for failure on the applicable eCRF.
9.2
Monitoring Subject Dosing Compliance
Study medication will be administered while subjects are under observation in the clinical research 
unit. Following administration of the study drug, appropriate mouth and/or hand checks will be 
performed to ensure that the dose is swallowed and noted in the source document. The date and 
time of each dose will be recorded in the source documents and on the eCRFs. An inventory of the 
study drug supplies dispensed will be performed by the site pharmacist or authorized study 
designee and recorded onto the Drug Accountability Log in the subject’s source document records 
or equivalent. The exact dose time of consecutive subjects may be staggered to facilitate logistics 
at the site.
9.3
Schedule of Observations and Procedures
The schedule for all study-related procedures for all evaluations is shown in Appendix A. 
Assessments should be completed at the designated visit/time point(s).
9.3.1
Screening 
Subjects will be screened within 28 days prior to randomization. Screening may consist of 1 or 
more visits. Subjects will sign an informed consent form at the first visit and return to the clinic in 
a fasted state for safety laboratory testing at the second visit. Subjects will be screened in 
accordance with predefined inclusion and exclusion criteria as described in Section 7.0. A screen 
failure rate of approximately 50% is anticipated. Therefore, an estimated 144 subjects will be 
screened in order to enroll 72 subjects. See Section 9.1.14 for procedures for documenting 
screening failures.
9.3.2
Study Randomization 
Study randomization will take place on Day 1 of Period 1.
If the subject has satisfied all of the inclusion criteria and none of the exclusion criteria for 
randomization, the subject should be randomized as described in Section 8.2. Subjects will be 
administered the first dose of test or reference drug in the unit under the supervision of the 
investigator or designee, as described in Section 8.2. The procedure for documenting Screening 
failures is provided in Section 9.1.14.
9.3.3
Drug Intake/Washout Period 
Subjects will be confined to the clinic from Check-in (Day -1) of Dosing Period 1 until the 24-hour 
blood sample has been collected on Day 2 of Dosing Period 1 and from Day 7 of Dosing Periods 1,

2, and 3 until the 24-hour blood sample has been collected on Day 2 of Dosing Periods 2, 3, and 4, 
respectively. Subjects will be discharged or released from the unit unless deemed inappropriate by 
the investigator because of safety concerns. Subjects will return to the clinic for the 36-hour blood 
sample collection on Day 2 and on Days 3 and 4 of each period to complete study procedures.
There is a 7-day washout interval between the dose in each period.
The study consists of a Screening Period (Days -28 to Day-2) and 4 Drug Intake Periods. A 
washout interval of 7 days (beginning immediately after dosing on Day 1 of Period 1) will separate 
the doses of each study period. Subjects will be admitted into the clinic on Day -1 (at least 10 hours 
prior to study drug administration), will be dosed on Day 1 and discharged from the clinic after the 
24-hour blood sample has been collected on Day 2 of each period. Blood samples for 
determination of alogliptin and pioglitazone plasma concentrations will be collected prior to 
dosing on Day 1 through 72 hours postdose. 
9.3.4
Final Visit/ Early Termination
If a subject discontinues, the reason for discontinuation must be documented in the source 
document and eCRF. The PK sample collection should be collected at the Early Termination Visit, 
if possible and relatively close to a protocol-specified time point. The site may seek guidance. For 
example, collect samples if early withdrawal is due to an AE, and/or if several hours elapsed since 
last blood draw.
Final Visit procedures will be performed on Day 4 of Period 4.
For all subjects receiving study drug, the investigator must complete the End of Study eCRF page.
9.3.5
Follow-Up Visit/Telephone Call 
At 14 days ±2 days following the last dose of study drug a Follow-up telephone call will be made 
by the site to inquire for any ongoing AEs or SAEs, new AEs or SAEs, and concomitant 
medications taken since final dose of study medication. Subject who withdrew consent should still 
be contacted for a safety Follow-up telephone call, but the contact should only be recorded in the 
medical records and not in the eCRF, according to data protection regulations.

The approximate total volume of blood collected from one subject for the study is 469 mL.
Blood samples for PK analysis will be collected via venous catheter through the 24-hour postdose 
PK sample in each period. With use of a peripheral venous catheter, the catheter will be irrigated 
with 0.5 mL heparinized saline solution (500 ME per 100 mL of 0.9% NaCl) after each blood 
sampling or after the catheter is inserted, in order to avoid catheter thrombosis. In addition, prior to 
taking each PK blood sample from the catheter, 1 mL blood will be drawn and discarded, in order 
to take into account the holdup volume (approximately 0.1 mL) within the catheter. Blood samples 
will be collected via venipuncture in cases of catheter thrombosis and for outpatient blood 
sampling at 36, 48, and 72 hours postdose.

PREDOSE EVENTS AND ADVERSE EVENTS
10.1
Definitions
10.1.1 Predose AEs
A predose AE is defined as any untoward medical occurrence in a clinical investigation subject 
who has signed informed consent to participate in a study but prior to administration of any study 
medication. Any AE, including abnormalities in laboratory, ECG, vital signs, or physical 
examination, will exclude the subject from participating in this clinical study. 
10.1.2 AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug; it does not necessarily have to have a causal relationship with this dosing.
An AE can therefore be any unfavorable and unintended sign (eg, abnormal laboratory value), 
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 AEs
An untoward finding generally may:

Indicate a new diagnosis.

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study drug or a concomitant medication.

Be considered unfavorable by the investigator for any reason. 
AEs caused by a study procedure (eg, a bruise after blood draw) should be recorded as an AE.
Diagnoses vs signs and symptoms:

Each event should be recorded to represent a single diagnosis. Accompanying signs (including 
abnormal laboratory values or ECG findings) or symptoms should NOT be recorded as 
additional AEs. If a diagnosis is unknown, sign(s) or symptom(s) should be recorded 
appropriately as an AE(s).
Laboratory values and ECG findings:

Changes in laboratory values or ECG findings are considered to be AEs. Repeated or 
additional noninvasive testing for verification, evaluation or monitoring of an abnormality is 
allowed.

If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (eg, increased creatinine in renal failure), the diagnosis only should be 
reported appropriately as an AE.

Protocol Incorporating Amendment No 02
23 January 2018
CONFIDENTIAL
Pre-existing conditions:

Subjects with pre-existing medical conditions will not be enrolled to this study.
Worsening of AEs:

If the subject experiences a worsening or complication of an AE, the worsening or 
complication should be recorded as a new AE. Investigators should ensure that the AE term 
recorded captures the change in the condition (eg, “worsening of…”).
Changes in intensity of AEs:

If the subject experiences changes in intensity of an AE, the event should be captured once 
with the maximum intensity recorded.
Elective surgeries or procedures:

Elective surgeries or procedures are not permitted during the trial; should they be required, the 
subject will be withdrawn. 
Overdose:

Cases of overdose with any medication without manifested side effects are NOT considered 
AEs, but instead will be documented on an Overdose page of the eCRF. Any manifested side 
effects will be considered AEs and will be recorded on the AE page of the eCRF.
10.1.4 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
if it were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. Is a CONGENITAL ANOMALY/BIRTH DEFECT.
6. Is an IMPORTANT MEDICAL EVENT that satisfies any of the following:

May require intervention to prevent items 1 through 5 above.

May expose the subject to danger, even though the event is not immediately life 
threatening or fatal or does not result in hospitalization.

Includes any event or synonym described in the Takeda Medically Significant AE List 
(Table 10.a).

Note: Terms identified on the Medically Significant AE List represent the broad medical concepts to be considered as 
“Important Medical Events” satisfying SAE reporting requirements.
Predose events that fulfill 1 or more of the serious criteria above are also to be considered SAEs 
and should be reported and followed up in the same manner (see Sections 10.2.2 and 10.3).
10.1.5 AEs of Special Interest
An AE of special interest (AESI), serious or non-serious, is one of scientific and medical concern 
specific to the compound or program, for which ongoing monitoring and rapid communication by 
the investigator to Takeda may be appropriate. Such events may require further investigation in 
order to characterize and understand them and would be described in protocols and instructions 
provided for investigators as to how and when they should be reported to Takeda. Pancreatitis, 
hypersensitivity, and hepatic events are considered AESIs and full details of the event should be 
recorded using the relevant AESI forms.
10.1.6 Intensity of AEs
The different categories of intensity (severity) are characterized as follows:
Mild:
The event is transient and easily tolerated by the subject.
Moderate:
The event causes the subject discomfort and interrupts the subject’s usual activities.
Severe:
The event causes considerable interference with the subject’s usual activities.

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

SYR-322-4833
Study No. Alogliptin-1002
Page 51 of 83
Protocol Incorporating Amendment No 02
23 January 2018
CONFIDENTIAL

Recovering/resolving – the intensity is lowered by 1 or more stages: the diagnosis or 
signs/symptoms has almost disappeared; the abnormal laboratory value improved, but has not 
returned to the normal range or to Baseline; the subject died from a cause other than the 
particular AE with the condition remaining “recovering/resolving”.

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/ symptoms or laboratory value on the last day of the observed 
study period has got worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE state remaining “Not recovered/not 
resolved”.

Resolved with sequelae – the subject recovered from an acute AE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis.

Fatal – the AEs which are considered as the cause of death.

Unknown – the course of the AE cannot be followed up due to hospital change or residence 
change at the end of the subject’s participation in the study.
10.2
Procedures
10.2.1 Collection and Reporting of AEs
10.2.1.1
AE Collection Period
Collection of AEs will commence from the time the subject signs the informed consent to 
participate in the study and continue until 14±2 days after Study Exit Visit or the last dose of study 
medication.
10.2.1.2
AE Reporting
At each study visit, the investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. 
All subjects experiencing AEs, whether considered associated with the use of the study drug or 
not, must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to Baseline or until there is a satisfactory explanation for the 
changes observed. All AEs will be documented in the AE page of the eCRF, whether or not the 
investigator concludes that the event is related to the study drug. The following information will be 
documented for each event:
1. Event term.
2. Start and stop date.
3. Frequency.

AEs of Special Interest 
If an AESI, including but not limited to hypersensitivity, pancreatitis, hepatic disorders, occurs 
during the drug intake period or the follow-up period, is considered to be clinically significant 
based on the criteria below, it should be recorded in a targeted form or an SAE Form. The form 
should be completed and reported to the SAE email address within 24 hours.
AESI criteria include:

Laboratory value threshold if applicable.

Premature termination for the AESI, if applicable.

Any other specific criteria.
The AESIs have to be recorded as AEs in the eCRF. An evaluation form along with all other 
required documentation must be submitted to the sponsor.
10.2.2 Collection and Reporting of SAEs
When an SAE occurs through the AE collection period it should be reported according to the 
following procedure:
A Takeda SAE form must be completed, in English, and signed by the investigator immediately or 
within 24 hours of first onset or notification of the event. The information should be completed as 
fully as possible but contain, at a minimum:

A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study drug(s).

Causality assessment.
The SAE form should be transmitted within 24 hours to the attention of the contact listed in 
Section 1.0.

Any SAE spontaneously reported to the investigator following the AE collection period should be 
reported to the sponsor if considered related to study participation.
10.2.3 Reporting of Abnormal Liver Function Tests 
If a subject is noted to have ALT or AST elevated >3 ×ULN on 2 consecutive occasions, the 
abnormality should be recorded as an AE. In addition, a liver function test (LFT) Increases eCRF 
must be completed providing additional information on relevant recent history, risk factors, 
clinical signs and symptoms and results of any additional diagnostic tests performed.
If a subject is noted to have ALT or AST >3 ×ULN and total bilirubin >2 ×ULN for which an 
alternative etiology has not been identified, the event should be recorded as an SAE and reported 
as per Section 10.2.2. The investigator must contact the Medical Monitor for discussion of the 
relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or B or 
other acute liver disease or medical history/concurrent medical conditions. Follow-up laboratory 
tests as described in Section 9.1.8 must also be performed. In addition, an LFT Increases eCRF 
must be completed and transmitted with the Takeda SAE form (as per Section 10.2.2).
10.3
Follow-up of SAEs
If information is not available at the time of the first report becomes available at a later date, the 
investigator should complete a follow-up SAE form or provide other written documentation and 
fax it immediately within 24 hours of receipt. Copies of any relevant data from the hospital notes 
(eg, ECGs, laboratory tests, discharge summary, postmortem results) should be sent to the 
addressee, if requested.
All SAEs should be followed up until resolution or permanent outcome of the event. The timelines 
and procedure for follow-up reports are the same as those for the initial report.
10.3.1 Safety Reporting to Investigators, IRBs or IECs, and Regulatory Authorities 
The sponsor will be responsible for reporting all suspected unexpected serious adverse reactions 
(SUSARs) and any other applicable SAEs to regulatory authorities, including the European 
Medicines Agency (EMA), investigators and IRBs or IECs, as applicable, in accordance with 
national regulations in the countries where the study is conducted. Relative to the first awareness 
of the event by/or further provision to the sponsor or sponsor’s designee, SUSARs will be 
submitted to the regulatory authorities as expedited report within 7 days for fatal and 
life-threatening events and 15 days for other serious events, unless otherwise required by national 
regulations. The sponsor will also prepare an expedited report for other safety issues where these 
might materially alter the current benefit-risk assessment of the study drug/sponsor supplied drug 
or that would be sufficient to consider changes in the study drug/sponsor supplied drug 
administration or in the overall conduct of the trial. The study site also will forward a copy of all 
expedited reports to his or her IRB or IEC in accordance with local regulations.

CRFs (Electronic)
Completed eCRFs are required for each subject who signs an informed consent.
The sponsor or its designee will supply study sites with access to eCRFs. The sponsor will make 
arrangements to train appropriate site staff in the use of the eCRF. These forms are used to transmit 
the information collected in the performance of this study to the sponsor and regulatory authorities. 
eCRFs must be completed in English.
After completion of the entry process, computer logic checks will be run to identify items, such as 
inconsistent dates, missing data, and questionable values. Queries may be issued by Takeda 
personnel (or designees) and will be answered by the site. 
Corrections to eCRFs are recorded in an audit trail that captures the old information, the new 
information, identification of the person making the correction, the date the correction was made, 
and the reason for change. Reasons for significant corrections should additionally be included. 
The principal investigator must review the eCRFs for completeness and accuracy and must e-sign 
the appropriate eCRFs as indicated. Furthermore, the investigator must retain full responsibility 
for the accuracy and authenticity of all data entered on the eCRFs.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by the sponsor or its designee. The sponsor or its designee will be permitted to review the subject’s 
medical and hospital records pertinent to the study to ensure accuracy of the eCRFs. The 
completed eCRFs are the sole property of the sponsor and should not be made available in any 
form to third parties, except for authorized representatives of appropriate governmental health or 
regulatory authorities, without written permission of the sponsor.
12.2
Record Retention
The investigator agrees to keep the records stipulated in Section 12.1 and those documents that 
include (but are not limited to) the study-specific documents, the identification log of all 
participating subjects, medical records, temporary media such as thermal sensitive paper, source 
worksheets, all original signed and dated informed consent forms, subject authorization forms 
regarding the use of personal health information (if separate from the informed consent forms), 
electronic copy of eCRFs, including the audit trail, and detailed records of drug disposition to 
enable evaluations or audits from regulatory authorities, the sponsor or its designees. Any source 
documentation printed on degradable thermal sensitive paper should be photocopied by the site 
and filed with the original in the subject’s chart to ensure long-term legibility. Furthermore, 
International Conference on Harmonisation (ICH) E6 Section 4.9.5 requires the investigator to 
retain essential documents specified in ICH E6 (Section 8) until at least 2 years after the last

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

STATISTICAL METHODS
13.1
Statistical and Analytical Plans
A statistical analysis plan (SAP) will be prepared and finalized prior to database lock. This 
document will provide further details regarding the definition of analysis variables and analysis 
methodology to address all study objectives.
13.1.1 Analysis Sets
The safety set will include all randomized subjects who receive at least 1 dose of study medication, 
including subjects who do not complete the study. Subjects in this set will be used for demographic 
and baseline characteristics as well as safety summaries.
The PK set will consist of all subjects in the safety set who have sufficient plasma concentration 
data to facilitate the derivation of at least 1 PK parameter. Details regarding how to handle missing 
data will be predefined in the statistical analysis plan.
13.1.2 Analysis of Demographics and Other Baseline Characteristics
Demographic and baseline characteristics will be summarized for the Safety Set by sequence and 
overall. Summary statistics [number of non-missing values (N), mean, standard deviation (SD), 
median, minimum, and maximum] will be presented for continuous variables (eg, age and weight) 
and the number and percentage of subjects within each category will be presented for categorical 
variables (eg, gender, ethnicity, race). Individual subject demographic and baseline characteristics 
data will be listed.
13.1.3 PK Analysis
Descriptive statistics (eg, N, mean, SD, median, minimum, and maximum) will be used to 
summarize the plasma concentrations of alogliptin and pioglitazone by regimen and scheduled 
sampling time point. Individual plasma concentration data for alogliptin and pioglitazone will be 
presented in the data listings.
Descriptive statistics (N, mean, SD, SE, percent coefficient of variation [%CV], median, 
minimum, and maximum) will be used to summarize the PK parameters of alogliptin and 
pioglitazone for each regimen. Geometric means will be computed for AUCs and Cmax.
Statistical inference to determine if the FDC tablet is bioequivalent to alogliptin and pioglitazone 
administered as individual tablets will be performed using an analysis of variance (ANOVA) 
model with effects for regimen, period, sequence, and subjects nested within sequence. The effect 
due to subject nested within sequence will be considered a random effect in the ANOVA model 
while all other effects will be treated as fixed. The ANOVA model will be applied to the natural 
logarithms of AUC72 and Cmax of alogliptin or pioglitazone as dependent variables to compare the 
test and reference regimens.
Within the framework of ANOVA model for natural logarithms of AUC72 and Cmax, the ratios and 
the 90% confidence intervals (CIs) for the ratios of central values of the test regimen relative to the 

SYR-322-4833
Study No. Alogliptin-1002

CONFIDENTIAL
reference regimen will be provided. The ratios will be obtained as the antilog of the difference of 
the LS means on a natural logarithm scale, and the 90% CIs will be obtained by taking the antilog 
of the 90% CI for the difference between the LS means on the natural logarithmic scale. 
Bioequivalence between administration of alogliptin and pioglitazone as an FDC tablet and as 
individual tablets will be concluded if the 90% CIs are within the range of (0.80, 1.25) for Cmax and 
AUC72.
Alternative statistical analyses will be used if deemed appropriate.
13.1.4 Subject Condition Assessments
Subject condition assessments will be performed using the Safety Set. All subject condition 
assessments, including AEs, clinical laboratory evaluations, 12-lead ECG results, and vital signs 
will be summarized with descriptive statistics, where appropriate, and presented in the data 
listings.
All AEs will be coded using MedDRA and presented in the data listings.
A postdose AE is defined as an AE that occurs after the subject receives the first dose of study 
medication and within 30 days after the last dose of study medication is received. Summary of AEs 
will include numbers and percentages of subjects experiencing AEs by system organ class and 
preferred term. AEs will also be summarized based on their intensity and relationship to study 
medication by system organ class and preferred term. If a subject has more than 1 AE that codes to 
the same preferred term, the subject will be counted only once for that preferred term within 
regimen. Similarly, if a subject has more than 1 AE within a system organ class category, the 
subject will be counted only once in the system organ class category within the regimen. In the 
intensity summary, a subject will be counted only in the highest intensity category for each 
preferred term and each organ class. In the relationship to study medication summary, a subject 
will be counted only in the highest relationship category for each preferred term and each system 
organ class. Each summary table will include incidences of adverse events for each regimen and 
overall.
All AE summary tables will be listed in the SAP.
AEs will be summarized using preferred term and primary system organ class. 
Individual results for clinical hematology and serum chemistry laboratory tests that are outside of 
normal range and results that meet Takeda predefined criteria for markedly abnormal values will 
be considered as clinically significant and identified in summary tables, if applicable. Observed 
values and change from Baseline will be summarized by regimen. All laboratory values will be 
presented in the data listings.
Individual vital sign values that meet the Takeda predefined markedly abnormal criteria will be 
considered as clinically significant and identified in a summary table. The vital sign measurements 
at predefined time points and change from Baseline will be summarized by regimen. All vital signs 
data will be presented in the data listing.

Individual ECG measurements that meet the Takeda predefined markedly abnormal criteria will 
be considered as clinically significant and flagged and summarized in a table. Observed values will 
be summarized by regimens. All ECG data will be listed in the data listings.
13.2
Interim Analysis and Criteria for Early Termination
No interim analysis is planned.
13.3
Determination of Sample Size
A sample size of 72 subjects (18 per sequence) will be enrolled in this 4-period, 4-sequence 
crossover study. The sample size is appropriate to assess the bioavailability of alogliptin and 
pioglitazone from the FDC relative to the individual tablets and also provide greater than 80% 
power for Cmax of pioglitazone establishing bioequivalence between regimens for both strengths 
(SYR-322-4833 BL 25 mg+15 mg and SYR-322-4833 BL 25 mg+30 mg). This is based on 
acceptance ranges of 80% to 125%, the intra-subject variability (%CV) of 33% for Cmax of 
pioglitazone; the expected ratios of the central values for Cmax are between 0.95 and 1.05, and 
drop-out rate of 14%. Since the intra-subject variability for pioglitazone AUCt, and alogliptin Cmax
and AUCt is less than 33%, the power for assessing bioequivalence for pioglitazone AUCt and 
alogliptin Cmax and AUCt are each greater than 80% for both strengths.

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

15.2
Subject Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in the 
Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance with all 
applicable laws and regulations. The informed consent form, subject authorization form (if 
applicable), and subject information sheet (if applicable) describe the planned and permitted uses, 
transfers, and disclosures of the subject’s personal and personal health information for purposes of 
conducting the study. The informed consent form and the subject information sheet (if applicable) 
further explain the nature of the study, its objectives, and potential risks and benefits, as well as the 
date informed consent is given. The informed consent form will detail the requirements of the 
participant and the fact that he or she is free to withdraw at any time without giving a reason and 
without prejudice to his or her further medical care.
The investigator is responsible for the preparation, content, and IRB or IEC approval of the 
informed consent form and if applicable, the subject authorization form. The informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) must 
be approved by both the IRB or IEC and the sponsor prior to use.
The informed consent form, subject authorization form (if applicable), and subject information 
sheet (if applicable) must be written in a language fully comprehensible to the prospective subject. 
It is the responsibility of the investigator to explain the detailed elements of the informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) to the 
subject. Information should be given in both oral and written form whenever possible and in the 
manner deemed appropriate by the IRB or IEC.

The subject must be given ample opportunity to: (1) inquire about details of the study and (2) 
decide whether or not to participate in the study. If the subject determines he or she will participate 
in the study, then the informed consent form and subject authorization form (if applicable) must be 
signed and dated by the subject at the time of consent and prior to the subject entering into the 
study. The subjects should be instructed to sign using their legal names, not nicknames, using blue 
or black ballpoint ink. The investigator must also sign and date the informed consent form and 
subject authorization (if applicable) at the time of consent and prior to subject entering into the 
study; however, the sponsor may allow a designee of the investigator to sign to the extent 
permitted by applicable law.
Once signed, the original informed consent form, subject authorization form (if applicable), and 
subject information sheet (if applicable) will be stored in the investigator’s site file. The 
investigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed informed consent form, the signed subject authorization form 
(if applicable), and subject information sheet (if applicable) shall be given to the subject.
All revised informed consent forms must be reviewed and signed by relevant subjects in the same 
manner as the original informed consent. The date the revised consent was obtained should be 
recorded in the subject’s medical record, and the subject should receive a copy of the revised 
informed consent form.
15.3
Subject Confidentiality
The sponsor and designees affirm and uphold the principle of the subject’s right to protection 
against invasion of privacy. Throughout this study, a subject’s source data will only be linked to 
the sponsor’s clinical trial database or documentation via a subject identification number. As 
permitted by all applicable laws and regulations, limited subject attributes, such as sex, age, or date 
of birth, and subject initials may be used to verify the subject and accuracy of the subject’s unique 
identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit the monitor or the sponsor’s designee, representatives from any 
regulatory authority (eg, Ministry of Health of Russian Federation, Food and Drug Administration, 
Medicines and Healthcare products Regulatory Agency, Pharmaceuticals and Medical Devices 
Agency), the sponsor’s designated auditors, and the appropriate IRBs and IECs to review the 
subject’s original medical records (source data or documents), including, but not limited to, 
laboratory test result reports, ECG reports, admission and discharge summaries for hospital 
admissions occurring during a subject’s study participation, and autopsy reports. Access to a 
subject’s original medical records requires the specific authorization of the subject as part of the 
informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).

Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the study site agreement, any public disclosure 
(including publicly accessible websites) related to the protocol or study results, other than study 
recruitment materials and/or advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with 
this section and the study site agreement. In the event of any discrepancy between the protocol and 
the study site agreement, the study site agreement will prevail.
The investigator needs to obtain a prior written approval from the sponsor to publish any 
information from the study externally such as to a professional association.
15.4.2 Clinical Trial Registration
In order to ensure that information on clinical trials reaches the public in a timely manner and to 
comply with applicable laws, regulations and guidance, Takeda will, at a minimum register all 
interventional clinical trials it sponsors anywhere in the world on ClinicalTrials.gov and/or other 
publicly accessible websites before start of study, as defined in Takeda Policy/Standard. Takeda 
contact information, along with investigator’s city, state (for America), country, and recruiting 
status will be registered and available for public viewing. 
For some registries, Takeda will assist callers in locating study sites closest to their homes by 
providing the investigator name, address, and phone number to the callers requesting trial 
information. Once subjects receive investigator contact information, they may call the site 
requesting enrollment into the trial. The investigative sites are encouraged to handle the trial 
inquiries according to their established subject screening process. If the caller asks additional 
questions beyond the topic of trial enrollment, they should be referred to the sponsor. 
Any investigator who objects to the sponsor providing this information to callers must provide the 
sponsor with a written notice requesting that their information not be listed on the registry site. 
15.4.3 Clinical Trial Results Disclosure 
Takeda will post the results of clinical trials on ClinicalTrials.gov or other publicly accessible 
websites, as required by Takeda Policy/Standard, applicable laws and/or regulations.

Collection, Storage, and Shipment of PK Samples
Instructions for Processing of Plasma Samples for PK Analysis of Alogliptin and 
Pioglitazone
1. Collect 6 mL of venous blood into a chilled Becton-Dickinson Vacutainer. All alogliptin and 
pioglitazone blood samples should be collected into vacutainers containing K2EDTA.
2. Gently invert the vacutainer several times to mix the additive with the collected blood prior to 
centrifugation and place immediately on ice.
3. Centrifuge the vacutainers for 10 minutes at approximately 1100 to 1300 relative centrifugal 
force (RCF) at room temperature. Note: if using a collection device other than 
Becton-Dickinson, refer to manufacturer’s instruction for proper centrifugation force and time.
4. Immediately following centrifugation, gently remove plasma from the packed cells. To ensure 
a more homogeneous sample, all plasma should first be transferred into 1 aliquot. From there, 
split the plasma evenly between the 4 aliquots. A minimum of 0.5 mL needs to be obtained for 
each sample. Labeling may include protocol number (Alogliptin-1002), sample matrix (ie, 
plasma), analyte (alogliptin or pioglitazone), randomization sequence number, period, nominal 
day and time, and either “SET 1” (for original sample) or “SET 2” (for duplicate sample). 
Note: the “SET 1” samples should be transferred first and then the “SET 2” tubes transferred.
5. Cap the labeled storage tubes and freeze the plasma samples immediately at 
approximately -20°C or lower until shipment. No more than 45-60 minutes will elapse 
between blood collection and freezing the plasma sample.
Shipping of Plasma Samples Alogliptin and Pioglitazone
The following instructions are recommended unless they differ from the site’s standard operating 
procedures for labeling, packaging, or shipping of PK samples.
1. Biological samples (plasma) should be shipped on dry ice to prevent thawing during transit. 
Samples should be shipped only on Monday, Tuesday, or Wednesday, and at least 2 days prior 
to a national holiday, in order to minimize the possibility of samples in transit over a weekend 
or holiday. If duplicate samples are to be shipped, send SET 1 samples and await confirmation 
of arrival before shipping the duplicate SET 2 samples.
2. Before shipping, make sure the sample tubes are tightly sealed. Separate each subject’s 
samples as follows:
3. Separate the duplicate SET 2 samples from the SET 1 samples.
4. Place SET 1 samples for each subject into self-sealing bag (eg, Ziploc) containing additional 
absorbent material.
5. Using a permanent marker, write the 4-digit randomization sequence number, sample matrix 
(ie, plasma), number of samples, and “SET 1” on each self-sealing bag.
6. Place the bags of individual subject’s samples into a larger plastic bag so that samples are 
double bagged. Duplicate SET 2 samples should be returned to the freezer for storage. Repeat 

SYR-322-4833

CONFIDENTIAL
steps 3 through 6 above when preparing duplicate samples for shipment, except self-sealing 
bags should be marked “SET 2.”
7. An inventory of individual samples should accompany each shipment and should include the 
Sponsor’s name (Takeda), study medication (alogliptin, pioglitazone), protocol number 
(Alogliptin-1002), investigator’s name, sample type (ie, plasma) analyte (alogliptin, 
pioglitazone), subject randomization sequence number, period, nominal collection day and 
time, and intended sample storage conditions. When duplicate SET 2 samples are being 
shipped, make a copy of the original SET 1 sample inventory and mark as “SET 2.” Place the 
inventory paperwork into a large self-sealing bag. SET 1 samples will be shipped first on dry 
ice, followed by shipment of duplicate SET 2 samples after SET 1 samples have been received 
by the analytical laboratory.
8. For sample packing, utilize dry ice generously (eg, 20-25 pounds per day of transit) to 
safeguard against longer than expected shipping times and delays. Use newspaper or other 
material to insulate the double-bagged samples from direct contact with the dry ice. Place the 
sample bundles into a Styrofoam container (or other suitable container) and fill the excess 
space with dry ice slabs or ice pellets (preferably the latter). Make a note of the estimated 
weight of the dry ice used per shipping container.
9. Place the inventory paperwork (in a large self-sealing bag) on top of the dry ice in the 
Styrofoam container. Place the lid on the Styrofoam container and seal completely with 
strapping tape. Place the Styrofoam container in a cardboard shipping carton and seal securely 
with strapping tape.
10. Mark the outside of shipping carton(s) with a tally number (eg, 1 of 5, 2 of 5).
11. Affix an address label to each shipping carton. Complete the address label with the following 
information:
Plasma samples for alogliptin and pioglitazone
Affix a carbon dioxide label on each carton, specifically:
Carbon Dioxide Solid UN-1845
Class 9 PKG GR III
Quantity _____________________
(fill in weight to nearest lb/kg and specify unit of measure used)
12. Affix 2 dry ice symbol labels on opposite sides of the carton. Mark KEEP FROZEN on each 
carton. Specify a return address and contact person on the carton.
