INTRODUCTION
4.1
Background
Dexlansoprazole is a proton pump inhibitor (PPI) with prolonged elevation of intragastric pH. 
PPIs inhibit the secretion of H+ ions in the stomach by inhibiting the (H+, K+)-ATPase enzyme 
(proton pump) at the secretory surface of the gastric parietal cell [1]. Dexlansoprazole is the 
R-enantiomer of the racemate lansoprazole. Lansoprazole, initially approved in France in 1990 
and in China in 1994, is currently marketed in over 90 countries and has a well-established safety 
profile. 
Takeda Development Center Americas, Inc. developed dexlansoprazole delayed-release capsules 
(also referred to as dexlansoprazole modified-release capsules) as a new therapy for treating 
acid-related disorders including symptomatic non-erosive gastroesophageal reflux disease
(GERD), erosive esophagitis (EE), and maintenance of healed EE and relief of heartburn. 
Dexlansoprazole capsules are approved for use in adults (≥18 years of age) in over 35 countries in 
North and South America, Europe, Asia, and the Middle East. Dexlansoprazole capsules were first 
approved for use in adults in the United States in January 2009. The international birth date (IBD) 
is 30 January 2009.
The clinical pharmacology program for dexlansoprazole capsules was extensive and evaluated the 
pharmacokinetics (PK), pharmacodynamics, extrinsic factors (eg, drug-drug interactions and food 
effect), and intrinsic factors (eg, age, gender, race, hepatic impairment) [1]. Dexlansoprazole mean 
maximum observed plasma concentration (Cmax) and mean area under the plasma 
concentration-time curve (AUC) values appeared to increase proportionally to the dose following 
oral administration of dexlansoprazole delayed-release capsule single-doses or multiple-doses 
ranging from 30 to 120 mg. The apparent terminal disposition phase half-life (t1/2z) of 
dexlansoprazole typically ranged from 1 to 2 hours, regardless of the dose, and no appreciable 
accumulation of dexlansoprazole was observed following once daily (QD) dosing. In addition, the 
PK of dexlansoprazole were shown to be time independent based on the similar systemic exposure 
after oral administration of a single dose of dexlansoprazole capsules and that which was observed 
following QD oral dosing [2].
Dexlansoprazole is primarily metabolized by the cytochrome P450 (CYP) enzymes CYP3A4 and 
polymorphic CYP2C19 [1]. The CYP2C19 poor metabolizer (PM) phenotype is present in 12% to 
23% of the Asian population, and the prevalence of CYP2C19 PMs in Chinese subjects is similar 
to that of other Asian populations [3]. Study TAK-390MR/CPH-002 assessed the PK of multiple 
doses of dexlansoprazole 30 and 60 mg capsule doses in male Japanese PM and extensive 
metabolizer (EM) subjects. In the Japanese PMs, dexlansoprazole t1/2z was approximately 3 times 
longer than in EMs, and apparent clearance after extravascular administration (CL/F) in the EMs 
was approximately 4-times greater than PMs. Although the availability of PK data in PMs in the 
Caucasian and African American population is limited, it is expected that dexlansoprazole 
exposure in these races will be affected by CYP2C19 phenotypes as well.

The majority of the dexlansoprazole capsule phase 1 studies were conducted in the United States. 
As development of dexlansoprazole expands to other countries, additional studies are needed to 
bridge between the data acquired previously in North American and Asian populations.
4.2
Rationale for the Proposed Study
The rationale for the current study is to add to the current knowledge of dexlansoprazole by

Justification for Study Design, Dose, and Endpoints
This study was designed based on the requirements of the China Food and Drug Administration 
(CFDA) for successful registration of dexlansoprazole in China. Phase 3 safety and efficacy trials 
with dexlansoprazole will be performed concurrently in China. A single-dose study will provide 
adequate information on the PK of dexlansoprazole in Chinese subjects to allow the data to be 
bridged to data previously acquired in North American and Japanese populations at both the 
30 and 60 mg doses.
This is a single-center, open-label, single-dose, 2-arm parallel study using dexlansoprazole 
delayed-release capsules (30 and 60 mg). Healthy adult Chinese subjects will be enrolled. Since 
PPIs are intended to be used by both genders, effort will be made to enroll an equal number of men 
and women. The study will assess the PK of dexlansoprazole 30 and 60 mg delayed-release 
capsules.
The CYP2C19 PM phenotype is present in 12% to 23% of the Asian population, and the
prevalence of CYP2C19 PMs in Chinese subjects is similar to that of other Asian populations [3].

The CYP2C19 isozyme is a polymorphic enzyme that is involved in the metabolism of 
dexlansoprazole, and administration of dexlansoprazole may result in higher plasma levels in 
subjects who are CYP2C19 PMs [1]. Therefore, the CYP2C19 metabolizer status of the subjects 
will be determined and, if appropriate, the effect of metabolizer status on the PK of 
dexlansoprazole will be assessed.
The objective of the study is to evaluate the PK of dexlansoprazole at both doses that will be 
included in the phase 3 studies. Standard PK parameters will be calculated. The design of the study 
will provide information on the PK of a single dose of dexlansoprazole 30 and 60 mg in healthy 
Chinese subjects. The safety of dexlansoprazole delayed-release capsules has been evaluated 
following oral administration in phases 1 and 3 studies. In the previous phase 3 studies, 
dexlansoprazole 30 and 60 mg had a comparable safety profile to lansoprazole 30 mg. 
Dexlansoprazole delayed-release capsule doses of 30 and 60 mg were well tolerated.
6.3
Premature Termination or Suspension of Study or Investigational Site
6.3.1
Criteria for Premature Termination or Suspension of the Study
The study will be completed as planned unless one or more of the following criteria are satisfied 
that require temporary suspension or early termination of the study.

New information or other evaluation regarding the safety or efficacy of the study medication 
that indicates a change in the known risk/benefit profile for the compound, such that the 
risk/benefit is no longer acceptable for subjects participating in the study.

Significant violation of Good Clinical Practice (GCP) that compromises the ability to achieve 
the primary study objectives or compromises subject safety.
6.3.2
Criteria for Premature Termination or Suspension of Investigational Sites
A study site may be terminated prematurely or suspended if the site (including the investigator) is 
found in significant violation of GCP, protocol, or contractual agreement, is unable to ensure 
adequate performance of the study, or as otherwise permitted by the contractual agreement.
6.3.3
Procedures for Premature Termination or Suspension of the Study or the 
Participation of Investigational Site(s)
In the event that the sponsor, an institutional review board (IRB)/ independent ethics committee 
(IEC), or regulatory authority elects to terminate or suspend the study or the participation of an 
investigational site, a study-specific procedure for early termination or suspension will be 
provided by the sponsor; the procedure will be followed by applicable investigational sites during 
the course of termination or study suspension.

7.4
Diet, Fluid, and Activity Control
Diet and Fluid
During each day of the confinement period, subjects will receive standardized meals and an 
evening snack. The menu of the standardized meals from the clinical research site needs to be 
approved by Takeda before the implementation. The clinical research site will ensure the same 
meals are served to all subjects on Day 1. All subjects may consume water ad libitum except for 
1 hour before and 1 hour after drug administration.
During confinement, foods, and beverages listed in Table 7.a will be prohibited, and all subjects 
will be limited to only standardized meals and snacks provided by the site.
Subjects will fast for a minimum of 8 hours prior to dosing. On Day 1, breakfast will be served 
1 hour postdose. Lunch will be served approximately 4 hours postdose. Dinner will be served 
approximately 9 hours postdose. A snack will be served approximately 12 hours postdose. No

additional meals will be served on Day 1. The start and stop times of meals on Day 1 will be 
recorded in the source documentation and on the case report form (eCRF). Subjects will be fasting 
for a minimum of 8 hours prior to collection of safety labs on Day 2.
Activity Control
Subjects will refrain from strenuous exercise beginning upon confinement and for the duration of 
their participation in 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 should be 
recorded in the eCRF using the following categories. For screen failure subjects, refer to 
Section 9.1.15.
1. Pretreatment event (PTE) or adverse event (AE). The subject has experienced a PTE or AE that 
requires early termination because continued participation imposes an unacceptable risk to the 
subject’s health or the subject is unwilling to continue because of the PTE or AE.
2. Significant protocol deviation. The discovery after the first dose of study drug that the subject 
failed to meet protocol entry criteria or did not adhere to protocol requirements, and continued 
participation poses an unacceptable risk to the subject’s health.
3. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. Attempts to contact the subject must be documented.
4. Voluntary withdrawal. The subject (or subject’s legally acceptable representative) wishes to 
withdraw from the study. The reason for withdrawal, if provided, should be recorded in the 
eCRF.
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (ie, withdrawal due to an 
AE 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.

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. In 
addition, efforts should be made to perform all procedures scheduled for Early Termination as 
noted in Appendix A. Discontinued or withdrawn subjects will not be replaced after enrollment.

CLINICAL TRIAL MATERIAL MANAGEMENT
This section contains information regarding all medication and materials provided directly by the 
sponsor, and/or sourced by other means, that are required by the study protocol, including 
important sections describing the management of clinical trial material.
8.1
Study Medication and Materials
8.1.1
Dosage Form, Manufacturing, Packaging, and Labeling
The following study medications manufactured by Takeda Pharmaceutical Company Limited, 
Osaka, Japan will be provided for this study: 

Dexlansoprazole 30 mg delayed-release capsules.

Dexlansoprazole 60 mg delayed-release capsules.
The study drug will be foil/foil blistered and packaged in 1-day child resistant blister cards 
containing 1 capsule. The card label will be compliant with requirement of CFDA.
8.1.2
Storage
All clinical drug supplies used to conduct this study should be stored at: 20°C to 25°C; excursions 
allowed between 15°C and 30°C. 
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.
8.1.3
Dose and Regimen
Subjects will fast for a minimum of 8 hours prior to dosing. On Day 1, breakfast will be served 
1 hour postdose. Subjects may consume water ad libitum except for 1 hour before and 1 hour after 
drug administration. Dosing will commence at approximately 0800 hours on Day 1. Study drug 
will be administered with 240 mL of water. Subjects must drink all of the water provided with the 
dose.
Following administration of the study drug, hand and mouth checks will be performed to ensure 
that the study drug was swallowed. Although the timing of events requires that each subject will be 
consistently administered the appropriate study drug 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.

8.1.4
Overdose
An overdose is defined as a known deliberate or accidental administration of investigational 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 eCRF(s) according to Section 10.0, Pretreatment 
Events and Adverse Events.
Serious adverse events (SAEs) associated with overdose should be reported according to the 
procedure outlined in Section 10.2.2, Collection and Reporting of SAEs.
In the event of drug overdose, the subject should be treated symptomatically by the investigator.
8.2
Investigational Drug Assignment and Dispensing Procedures
The site will assign a 4-digit enrollment number in the order subjects become eligible for 
enrollment starting from 1001. This enrollment sequence number will be entered onto the eCRF. 
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 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 screening number which is assigned at the 
time the informed consent is obtained (Section 9.1.1) and which is used for all other procedures to 
identify the subjects throughout the study.
8.3
Accountability and Destruction of Sponsor-Supplied Drugs
Drug supplies will be counted and reconciled at the site before being returned to a designated 
facility for destruction. 
The investigator or designee must ensure that the study medication is used in accordance with the 
approved protocol and is dispensed only to subjects enrolled in the study. To document appropriate 
use of study medication, the investigator must maintain records of all study medication 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.

Dexlansoprazole

CONFIDENTIAL
The investigator must maintain 100% accountability for all study medication 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 expiry date is provided to the investigator. 

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 must record the current inventory of all study medication 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 study medication, 
expiry date and amount dispensed, including the initials of the person dispensing the drug. The log 
should include all required information as a separate entry for each subject to whom study 
medication is dispensed.
Prior to site closure or at appropriate intervals, a representative from the sponsor or its designee 
will perform clinical trial material accountability and reconciliation before clinical trial materials 
are returned to the sponsor or its designee for destruction. The investigator will retain the original 
documentation regarding clinical trial material accountability, return, and destruction, and copies 
will be sent to the sponsor or designee.
The investigator will be notified of any expiry date or retest date extension of clinical trial material 
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 clinical trial 
material for return to the sponsor or its designee for destruction.
In the event of expiry date extension of supplies already at the study site, clinical trial material may 
be relabeled with the new expiry date at that site. In such cases, Takeda or its designee will prepare 
additional labels, and all necessary documentation for completion of the procedure at the sites.

subject at the time 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, gender, race as described by the 
subject, height, weight, and smoking status of the subject at Screening. Caffeine consumption and 
alcohol history will also be collected at Screening. Medical history to be obtained will include 
determining whether the subject has any significant conditions or diseases that stopped 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 pretreatment assessment immediately prior to the 
start of investigational 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 findings from the baseline physical examination 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 PTE or concurrent medical 
condition in the source document and on the appropriate eCRF described in Section 10.0 or 
Section 9.1.7.
On subsequent examinations, any abnormal change from the pretreatment physical examination 
assessment occurring immediately prior to the start of the investigational drug (Day1) must be

CS change or new diagnosis as a result of a CS change, as determined by the investigator, will be 
recorded as an AE in source documentation and on the PTE/AE eCRF described in Section 10.0.
9.1.4
Weight, 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:
Metric:
BMI = weight (kg)/[height (m)]2
Height will be collected in centimeters to 1 decimal place and weight will be collected in 
kilograms (kg) to 1 decimal place. BMI will only be calculated at the Screening Visit and results
for BMI will be expressed with 1 decimal place.
Example: Height=176.2 cm (or 1.762 m), weight=79.2 kg; BMI=79.2/1.7622=25.5 kg/m2.
9.1.5
Vital Sign Procedure
Vital signs will include oral or axillary body temperature measurement, sitting blood pressure 
(after 5 minutes resting), respiration rate and pulse beats per minute (bpm). Only blood pressure 
and pulse will be taken on Check-in (Day -1) through Day 2.
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. 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
Concurrent medical conditions are those significant ongoing conditions or diseases that are present 
at signing of informed consent. This includes clinically significant laboratory, ECG, or physical 
examination abnormalities noted at Screening. The condition (ie, diagnosis) should be described.
9.1.8
Procedures for Clinical Laboratory Samples
All samples will be collected in accordance with acceptable laboratory procedures. The maximum 
volume of blood at any single visit is approximately 84 mL, and the total volume of blood for the 
study is approximately 152 mL. Laboratory samples will be taken following a minimum 8-hour 
overnight fast on the days stipulated in the Schedule of Study Procedures (Appendix A).

If subjects experience ALT or AST >3×ULN, follow-up laboratory tests (at a minimum, serum 
alkaline phosphatase, ALT, AST, total bilirubin, GGT, and INR) should be performed within a 
maximum of 7 days and preferably within 48-72 hours after the abnormality was found.
(Please refer to Section 10.2.3 for the appropriate guidance on Reporting of Abnormal Liver 
Function Tests in relation to ALT or AST >3×ULN in conjunction with total bilirubin >2×ULN.)
If the ALT or AST remains elevated >3×ULN on these 2 consecutive occasions, the investigator 
must contact the Medical Monitor for consideration of additional testing, close monitoring, 
possible discontinuation of study medication, 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 Reporting of Abnormal Liver Function Tests for reporting requirements).
Laboratory reports must be signed and dated by the principal investigator or the study doctor 
delegated by the principal investigator indicating that the report has been reviewed and any 
abnormalities have been assessed for clinical significance.
All clinically significant laboratory abnormalities must be recorded as a PTE/AE in the subject’s 
source documents and on the appropriate eCRF. A clinically significant laboratory abnormality 
that has been verified by retesting will be followed until the abnormality returns to an acceptable 
level or a satisfactory explanation has been obtained.
9.1.9
Contraception and Pregnancy Avoidance Procedure
From signing of informed consent, throughout the duration of the study, and for 30 days after last 
dose of study medication, nonsterilized** men who are sexually active with a woman of 
childbearing potential* must use barrier contraception (eg, condom with spermicidal cream or 
jelly). In addition, they must be advised not to donate sperm during this period.
From signing of informed consent, throughout the duration of the study, and for 30 days after last 
dose of study medication, female subjects of childbearing potential* who are sexually active with a 
nonsterilized male partner** must use adequate contraception. In addition they must be advised 
not to donate ova during this period.
*Women NOT of childbearing potential are defined as those who have been surgically sterilized 
(hysterectomy, bilateral oophorectomy or tubal ligation) or who are postmenopausal (defined as
continuous amenorrhea of at least 1 year and FSH>40 IU/L or at least 5 years since last regular 
menses, confirmed before any study medication is implemented, confirmed before any study 
medication is administered). Subject without bilateral tubal ligation documentation must follow 
one of the other methods of contraception as described below.
**Sterilized men should be at least 1 year postvasectomy and have confirmed that they have 
obtained documentation of the absence of sperm in the ejaculate.
An acceptable method of contraception is defined as one that has no higher than a 1% failure rate. 
In this study, where medications and devices containing hormones are included (provided the 
subject has been on a stable dose for a minimum of 90 days prior to Day 1), the only acceptable 
methods of contraception are:

Barrier methods (each time the 
subject has intercourse):
Intrauterine devices 
(IUDs):
Hormonal contraceptives:

Cap (plus spermicidal cream or 
jelly) PLUS male condom and 
spermicide.

Diaphragm (plus spermicidal 
cream or jelly) PLUS male 
condom and spermicide.

Copper T PLUS 
condom or spermicide.

Progesterone T PLUS 
condom or spermicide.

Implants.

Hormone shot/injection.

Combined pill.

Minipill.

Patch.

Vaginal ring PLUS male 
condom and spermicide.
Subjects will be provided with information on acceptable methods of contraception as part of the 
subject informed consent process and will be asked to sign a consent form stating that they 
understand the requirements for avoidance of pregnancy, donation of ova, and sperm donation
during the course of the study.
During the course of the study, regular serum 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 and sperm donation as part of the study procedures. In addition to a 
negative serum hCG pregnancy test at Screening, subjects also must have a negative serum hCG 
pregnancy test Check-in (Day-1) prior to receiving any dose of study medication. Women will also 
be given a serum hCG pregnancy test upon Study Exit (Day 2) or Early Termination.
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 man during the study or for up to 30 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, eg, after Day 1 or within 
30 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 woman or female partner of a man subject agrees to the primary care physician being 
informed, the investigator should notify the primary care physician that the subject/female partner 
of the subject was participating in a clinical study at the time she became pregnant and provide 
details of treatment 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.

9.1.11 ECG Procedure
A standard 12-lead ECG will be recorded at the time points stipulated in Appendix A. The 
investigator (or a qualified observer at the investigational site) will interpret the ECG using 1 of the 
following categories: within normal limits, abnormal but not clinically significant, or abnormal 
and clinically significant.
The results of the ECG will be captured on the source documents and appropriate eCRF and the 
original hard copies should be kept as source documentation. ECGs on thermal paper must be 
photocopied and the copy should be kept in the subjects’ source documents.
All stationary 12-lead ECG machines will be supplied by the site. The ECGs should be collected 
following an approximate 5-minute rest period. Should technical difficulties occur during 
collection of the ECG, a reasonable attempt should be made to repeat the ECG shortly after the 
failed attempt.
9.1.12 Sample Collection for Genotype Analysis
Genotyping and phenotyping analysis for CYP2C19 will be required for all subjects because 
dexlansoprazole is metabolized by the polymorphic isozyme CYP2C19. On Day 1, one blood 
sample (approximately 2 mL) for genotype analysis will be collected into vacutainers containing 
anticoagulant K2EDTA according to the schedule in Appendix A. Instructions for sample 
processing and shipment are provided in Appendix E.
9.1.13 Pharmacokinetic Sample Collection
9.1.13.1 Collection of Blood for Pharmacokinetic Sampling
On Day 1, blood samples (one 6-mL sample per scheduled time) for the determination of 
dexlansoprazole plasma concentrations will be collected into chilled vacutainers containing 
anticoagulant K2EDTA according to the schedule in Appendix A.
Instructions for sample processing and shipment are provided in Appendix E.
Blood samples will be collected according to Table 9.b.

9.1.15 Documentation of Screen Failure
Investigators must account for all subjects who sign informed consent. If the subject is found to be 
not eligible at this visit, the investigator should complete the relevant eCRF.
The primary reason for screen failure is recorded in the eCRF using the following categories:

PTE/AE.

Did not meet inclusion criteria or did meet exclusion criteria.

Significant protocol deviation.

Lost to follow-up.

Voluntary withdrawal <specify reason>.

Study termination.

Other <specify reason>.
Subject numbers assigned to subjects who fail screening should not be reused.
9.1.16 Documentation of Study Entrance
Only subjects who meet all of the inclusion criteria and none of the exclusion criteria are eligible 
for entrance into the study.

Monitoring Subject Treatment Compliance
Study medication will be administered while subjects are under observation in the clinical research 
unit. Following administration of the study medication, 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 medication supplies dispensed will be performed by the site pharmacist or authorized study 
designee and recorded onto the Drug Accountability Log in the subject’s source document records 
or equivalent. The exact dose time of consecutive subjects may be staggered to facilitate logistics 
at the site.

PRETREATMENT EVENTS AND ADVERSE EVENTS
10.1
Definitions
10.1.1 PTEs
A PTE is defined as any untoward medical occurrence in a clinical investigation subject who has 
signed informed consent to participate in a study but prior to administration of any study drug; it 
does not necessarily have to have a causal relationship with study participation.
10.1.2 AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a drug whether or 
not it is considered related to the drug.
10.1.3 Additional Points to Consider for PTEs and AEs
An untoward finding generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition. (Intermittent 
events for pre-existing conditions underlying disease should not be considered PTEs or AEs.)

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study medication or a concomitant medication.

Be considered unfavorable by the investigator for any reason. 

PTEs/AEs caused by a study procedure (eg, a bruise after blood draw) should be recorded as a 
PTE/AE.
Diagnoses versus 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 a PTE(s) or as an AE(s).
Laboratory values and ECG findings:

Changes in laboratory values or ECG parameters are only considered to be PTEs or AEs if they 
are judged to be clinically significant (ie, if some action or intervention is required or if the 
investigator judges the change to be beyond the range of normal physiologic fluctuation). A 
laboratory re-test and/or continued monitoring of an abnormal value are not considered an 

Dexlansoprazole
Study No. TAK-390MR_106

Protocol Incorporating Amendment No. 03
28 November2017
CONFIDENTIAL
intervention. In addition, repeated or additional noninvasive testing for verification, evaluation 
or monitoring of an abnormality is not considered an intervention.

If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (eg, increased creatinine in renal failure), the diagnosis only should be 
reported appropriately as a PTE or as an AE.
Pre-existing conditions:

Pre-existing conditions (present at the time of signing of informed consent) are considered 
concurrent medical conditions and should NOT be recorded as PTEs or AEs. Baseline 
evaluations (eg, laboratory tests, ECG, X-rays etc.) should NOT be recorded as PTEs unless 
related to study procedures. However, if the subject experiences a worsening or complication 
of such a concurrent condition, the worsening or complication should be recorded 
appropriately as a PTE (worsening or complication occurs before start of study drug) or an AE 
(worsening or complication occurs after start of study drug). Investigators should ensure that 
the event term recorded captures the change in the condition (eg, “worsening of…”).

If a subject has a pre-existing episodic condition (eg, asthma, epilepsy) any occurrence of an 
episode should only be captured as a PTE/AE if the episodes become more frequent, serious or 
severe in nature, that is, investigators should ensure that the AE term recorded captures the 
change in the condition from Baseline (eg “worsening of…”).

If a subject has a degenerative concurrent condition (eg, cataracts, rheumatoid arthritis), 
worsening of the condition should only be captured as a PTE/AE if occurring to a greater 
extent to that which would be expected. Again, investigators should ensure that the AE term 
recorded captures the change in the condition (eg, “worsening of…”).
Worsening of PTEs or AEs:

If the subject experiences a worsening or complication of a PTE after starting administration of 
the study medication, the worsening or complication should be recorded appropriately as an 
AE. Investigators should ensure that the AE term recorded captures the change in the condition 
(eg, “worsening of…”).

If the subject experiences a worsening or complication of an AE after any change in study 
medication, the worsening or complication should be recorded as a new AE. Investigators 
should ensure that the AE term recorded captures the change in the condition (eg, “worsening 
of…”).
Changes in severity of AEs /Serious PTEs:

If the subject experiences changes in severity of an AE/serious PTE, the event should be 
captured once with the maximum severity recorded.
Preplanned surgeries or procedures:

Preplanned procedures (surgeries or therapies) that were scheduled prior to signing of 
informed consent are not considered PTEs or AEs. However, if a preplanned procedure is 

Dexlansoprazole
Study No. TAK-390MR_106
Page 39 of 71
Protocol Incorporating Amendment No. 03
28 November2017
CONFIDENTIAL
performed early (eg, as an emergency) due to a worsening of the pre-existing condition, the 
worsening of the condition should be captured appropriately as a PTE or an AE. Complications 
resulting from any planned surgery should be reported as AEs.
Elective surgeries or procedures:

Elective procedures performed where there is no change in the subject’s medical condition 
should not be recorded as PTEs or AEs, but should be documented in the subject’s source 
documents. Complications resulting from an elective surgery should be reported as AEs.
Overdose:

Cases of overdose with any medication without manifested side effects are NOT considered 
PTEs or AEs, but instead will be documented on an Overdose page of the eCRF. Any 
manifested side effects will be considered PTEs or AEs and will be recorded on the AE page of 
the eCRF.
10.1.4 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
if it were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. 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).

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

Action Concerning Study Drug 

Drug withdrawn – a study medication is stopped due to the particular AE.

Dose not changed – the particular AE did not require stopping a study medication.

Unknown – only to be used if it has not been possible to determine what action has been taken.

Not Applicable – a study medication was stopped for a reason other than the particular AE 
eg, the study has been terminated, the subject died, dosing with study medication was already 
stopped before the onset of the AE.

Dose Reduced – the dose was reduced due to the particular AE.

Dose Interrupted – the dose was interrupted due to the particular AE.
10.1.12
Outcome

Recovered/Resolved – Subject returned to first assessment status with respect to the AE/PTE.

Recovering/Resolving – the intensity is lowered by one or more stages: the diagnosis or 
signs/symptoms has almost disappeared; the abnormal laboratory value improved, but has not 
returned to the normal range or to baseline; the subject died from a cause other than the 
particular AE/PTE with the condition remaining “recovering/resolving”.

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/ symptoms or laboratory value on the last day of the observed 
study period has got worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE/PTE state remaining “Not 
recovered/not resolved”.

Resolved with sequelae – the subject recovered from an acute AE/PTE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis.

Fatal – the AEs/PTEs which are considered as the cause of death.

10.2
Procedures
10.2.1 Collection and Reporting of AEs
10.2.1.1 PTE and AE Collection Period
Collection of PTEs will commence from the time the subject signs the informed consent to 
participate in the study and continue until the subject is first administered study medication 
(Day 1) or until screen failure. For subjects who discontinue prior to study medication 
administration, PTEs are collected until the subject discontinues study participation.
Collection of AEs will commence from the time that the subject is first administered study 
medication (Day 1). Routine collection of AEs will continue until Final Visit or Early 
Termination. A follow-up site/telephone visit will be made by each subject 5 to 10 days following 
the last dose of study drug to collect any AEs that may have occurred.
10.2.1.2 PTE and AE Reporting
At each study visit, the investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. Subjects experiencing a 
serious PTE must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or there is a satisfactory explanation for the change. 
Non-serious PTEs, related or unrelated to the study procedure, need not to be followed-up for the 
purposes of the protocol.
All subjects experiencing AEs, whether considered associated with the use of the study medication 
or not, must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to baseline or until there is a satisfactory explanation for the 
changes observed. All PTEs and AEs will be documented in the PTE/AE page of the eCRF, 
whether or not the investigator concludes that the event is related to the drug treatment. The

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 medication(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.
Reporting of Serious PTEs will follow the procedure described for SAEs.
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, an 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, 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 an 
investigational medicinal product or that would be sufficient to consider changes in the 
investigational medicinal products administration or in the overall conduct of the trial. The 
investigational site also will forward a copy of all expedited reports to his or her IRB or IEC in 
accordance with national regulations.

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the Data Management Plan. 
AEs, PTEs, medical history, and concurrent conditions will be coded using the Medical Dictionary 
for Regulatory Activities (MedDRA). Drugs will be coded using the World Health Organization 
Drug Dictionary (WHODRUG).
12.1
CRFs (Electronic and Paper)
Completed eCRFs are required for each subject who signs an informed consent.
The sponsor or its designee will supply investigative sites with access to eCRFs. The sponsor will 
make arrangements to train appropriate site staff in the use of the eCRF. These forms are used to 
transmit the information collected in the performance of this study to the sponsor and regulatory 
authorities. eCRFs must be completed in English. 
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. 
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.
After the lock of the clinical study database, any change of, modification of or addition to the data 
on the eCRF should be made by the investigator with use of change and modification records of 
the eCRFs. The principal investigator must review the data change for completeness and accuracy, 
and must sign and date.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by study monitors. The sponsor or its designee will be permitted to review the subject’s medical 
and hospital records pertinent to the study to ensure accuracy of the eCRFs. The completed eCRFs 
are the sole property of the sponsor and should not be made available in any form to third parties, 
except for authorized representatives of appropriate governmental health or regulatory authorities, 
without written permission of the sponsor.
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 should be 
copied and certified, 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 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 

Dexlansoprazole
Study No. TAK-390MR_106

requires the investigator to retain essential documents specified in ICH E6 (Section 8) until at least 
2 years after the last approval of a marketing application for a specified drug indication being 
investigated or, if an application is not approved, until at least 2 years after the investigation is 
discontinued and regulatory authorities are notified. In addition, ICH E6 Section 4.9.5 states that 
the study records should be retained until an amount of time specified by applicable regulatory 
requirements or for a time specified in the Clinical Study Site Agreement between the investigator 
and sponsor.
Refer to the phase 1 Site Specifications document 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. 
The targeted review plan will be conducted prior to database lock. This review will assess the 
accuracy and completeness of the study database, subject evaluability, and appropriateness of the 
planned statistical methods.
13.1.1 Analysis Sets
All subjects who are enrolled in the study and take at least 1 dose of study drug will be included in 
the safety set.
All subjects who receive at least 1 dose of study drug and have at least 1 measureable plasma 
concentration of dexlansoprazole will be included in the PK set. 
13.1.2 Analysis of Demographics and Other Baseline Characteristics
Demographic and baseline characteristics will be summarized by dose group. Summary statistics 
(number of subjects, mean, median, SD and range) will be generated for continuous variables (eg, 
age, weight, and body mass index) and the number and percentage of subjects within each category 
will be presented for categorical variables (eg, gender, race and ethnicity).
13.1.3 Pharmacokinetic Analysis
The concentration of dexlansoprazole in plasma will be summarized by scheduled sampling time 
points and dose group using descriptive statistics. Individual plasma concentration data will be 
presented in a data listing.
Descriptive statistics (number of subjects, arithmetic mean, SD, %CV, median, minimum and 
maximum) will be used to summarize the plasma PK parameters for dexlansoprazole from each 
dose group.
A more detailed analysis will be presented in the SAP.
13.1.4 Safety Analysis
All AEs will be coded by system organ class (SOC) and preferred term (PT) using the MedDRA. 
Treatment-emergent adverse events (TEAEs) with onset occurring within 30 days (onset date –
last date of dose +1≤30) after study drug administration will be included in the summary tables. 
All AEs will be in the listings. TEAEs will be summarized by SOC and PT. The following 
summary tables will be included in the report: summary of TEAEs and drug-related AEs, 
relationship of AEs to study drug (related vs not related), severity of AEs, and related AEs. Data 
listings will be provided for all AEs including PTEs, TEAEs, AEs leading to study drug 
discontinuation, and SAEs.

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Study-Site Monitoring Visits
Monitoring visits to the study site will be made periodically during the study to ensure that all
aspects of the protocol are followed. Source documents will be reviewed for verification of data 
recorded on the eCRFs. Source documents are defined as original documents, data, and records. 
The investigator and institution guarantee access to source documents by the sponsor or its 
designee (CRO) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee 
(as long as blinding is not jeopardized), including but not limited to the Investigator’s Binder, 
study medication, subject medical records, informed consent documentation, documentation of 
subject authorization to use personal health information (if separate from the informed consent 
forms), and review of eCRFs and associated source documents. It is important that the investigator 
and other study personnel are available during the monitoring visits and that sufficient time is 
devoted to the process.
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.
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. However, 
blood samples not collected within the interval specified for the scheduled sample time should be 
reported to Takeda using the Protocol Deviation Form.

Quality Assurance Audits and Regulatory Agency Inspections
The study site also may be subject to quality assurance audits by the sponsor or designees. In this 
circumstance, the sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the medication is stored and prepared, and any other facility used during the study. In 
addition, there is the possibility that this study may be inspected by regulatory agencies, including 
those of foreign governments (eg, the CFDA, the Food and Drug Administration [FDA], the 
United Kingdom Medicines and Healthcare products Regulatory Agency, the Pharmaceuticals and 
Medical Devices Agency of Japan). If the study site is contacted for an inspection by a regulatory 
body, the sponsor should be notified immediately. The investigator and institution guarantee 
access for quality assurance auditors to all study documents as described in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This study will be conducted with the highest respect for the individual participants (ie, subjects) 
according to the protocol, the ethical principles that have their origin in the Declaration of 
Helsinki, and the ICH Harmonised Tripartite Guideline for GCP. Each investigator will conduct 
the study according to applicable local or regional regulatory requirements and align his or her 
conduct in accordance with the “Responsibilities of the Investigator” that are listed in Appendix B. 
The principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
15.1
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable state and federal/local requirements 
of each participating region. The sponsor or designee will require documentation noting all names 
and titles of members who make up the respective IRB or IEC. If any member of the IRB or IEC 
has direct participation in this study, written notification regarding his or her abstinence from 
voting must also be obtained. Those Americas sites unwilling to provide names and titles of all 
members due to privacy and conflict of interest concerns should instead provide a Federal Wide 
Assurance Number or comparable number assigned by the Department of Health and Human 
Services.
The sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure or package 
insert, a copy of the informed consent form, and, if applicable, subject recruitment materials and/or 
advertisements and other documents required by all applicable laws and regulations, must be 
submitted to a central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the 
protocol and subject informed consent must be obtained and submitted to the sponsor or designee 
before commencement of the study (ie, before shipment of the sponsor-supplied drug or study 
specific screening activity). The IRB or IEC approval must refer to the study by exact protocol 
title, number, and version date; identify versions of other documents (eg, informed consent form) 
reviewed; and state the approval date. The sponsor will ship drug and notify site once the sponsor 
has confirmed the adequacy of site regulatory documentation and, when applicable, the sponsor 
has received permission from competent authority to begin the trial. Until the site receives 
notification no protocol activities, including screening may occur.
Sites must adhere to all requirements stipulated by their respective IRB or IEC. This may include 
notification to the IRB or IEC regarding protocol amendments, updates to the informed consent 
form, recruitment materials intended for viewing by subjects, local safety reporting requirements, 
reports and updates regarding the ongoing review of the study at intervals specified by the 
respective IRB or IEC, and submission of the investigator’s final status report to IRB or IEC. All 
IRB and IEC approvals and relevant documentation for these items must be provided to the 
sponsor or its designee.
Subject incentives should not exert undue influence for participation. Payments to subjects must 
be approved by the IRB or IEC and sponsor.

15.2
Subject Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in the 
Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance with all 
applicable laws and regulations. The informed consent form, subject authorization form (if 
applicable), and subject information sheet (if applicable) describe the planned and permitted uses, 
transfers, and disclosures of the subject’s personal and personal health information for purposes of 
conducting the study. The informed consent form and the subject information sheet (if applicable) 
further explain the nature of the study, its objectives, and potential risks and benefits, as well as the 
date informed consent is given. The informed consent form will detail the requirements of the 
participant and the fact that he or she is free to withdraw at any time without giving a reason and 
without prejudice to his or her further medical care.
The investigator is responsible for the preparation, content, and IRB or IEC approval of the 
informed consent form and if applicable, the subject authorization form. The informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) must 
be approved by both the IRB or IEC and the sponsor prior to use.
The informed consent form, subject authorization form (if applicable), and subject information 
sheet (if applicable) must be written in a language fully comprehensible to the prospective subject. 
It is the responsibility of the investigator to explain the detailed elements of the informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) to the 
subject. Information should be given in both oral and written form whenever possible and in the 
manner deemed appropriate by the IRB or IEC. In the event the subject is not capable of rendering 
adequate written informed consent, then the subject’s legally acceptable representative may 
provide such consent for the subject in accordance with applicable laws and regulations.
The subject, or the subject’s legally acceptable representative, must be given ample opportunity to: 
(1) inquire about details of the study and (2) decide whether or not to participate in the study. If the 
subject, or the subject’s legally acceptable representative, determines he or she will participate in 
the study, then the informed consent form and subject authorization form (if applicable) must be 
signed and dated by the subject, or the subject’s legally acceptable representative, at the time of 
consent and prior to the subject entering into the study. The subject or the subject’s legally 
acceptable representative should be instructed to sign using their legal names, not nicknames, 
using blue or black ballpoint ink. The investigator must also sign and date the informed consent 
form and subject authorization (if applicable) at the time of consent and prior to subject entering 
into the study; however, the sponsor may allow a designee of the investigator to sign to the extent 
permitted by applicable law.
Once signed, the original informed consent form, subject authorization form (if applicable), and 
subject information sheet (if applicable) will be stored in the investigator’s site file. The 
investigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed informed consent form, the signed subject authorization form 
(if applicable), and subject information sheet (if applicable) shall be given to the subject.

Dexlansoprazole

CONFIDENTIAL
All revised informed consent forms must be reviewed and signed by relevant subjects or the 
relevant subject’s legally acceptable representative in the same manner as the original informed 
consent. The date the revised consent was obtained should be recorded in the subject’s medical 
record, and the subject should receive a copy of the revised informed consent form.
15.3
Subject Confidentiality
The sponsor and designees affirm and uphold the principle of the subject’s right to protection 
against invasion of privacy. Throughout this study, a subject’s source data will only be linked to 
the sponsor’s clinical study database or documentation via a unique identification number. As 
permitted by all applicable laws and regulations, limited subject attributes, such as sex, age, or date 
of birth, and subject initials may be used to verify the subject and accuracy of the subject’s unique 
identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the sponsor 
requires the investigator to permit its monitor or designee’s monitor, representatives from any 
regulatory authority (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs and IECs to review the subject’s original medical records (source data or 
documents), including, but not limited to, laboratory test result reports, ECG reports, admission 
and discharge summaries for hospital admissions occurring during a subject’s study participation, 
and autopsy reports. Access to a subject’s original medical records requires the specific 
authorization of the subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and/or advertisements, is the sole responsibility of the sponsor.
The sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with 
this section and the Clinical Study Site Agreement. In the event of any discrepancy between the 
protocol and the Clinical Study Site Agreement, the Clinical Study Site Agreement will prevail.

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

Collection, Storage, and Shipment of Bioanalytical Samples
Instructions for Processing of Plasma Samples for Pharmacokinetic Analysis
1. Collect 6 mL of venous blood into a chilled Becton-Dickinson Vacutainer. For all 
TAK-390MR samples, blood samples should be collected into vacutainers containing 
anticoagulant K2EDTA. 
2. Gently invert the vacutainer several times to mix the additive with the collected blood prior to 
centrifugation and place immediately on ice or keep at ambient temperature.
3. Centrifuge the vacutainers for 10 minutes at approximately 1200 relative centrifugal force 
(RCF) at approximately 4°C in a refrigerated centrifuge or at ambient 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. Split the 
plasma evenly between the 2 aliquots. A minimum of approximately 1.2 mL needs to be 
obtained for each sample. Labeling may include protocol number (TAK-390MR_106), matrix 
(ie, plasma), analyte (TAK-390MR), enrollment number, nominal day and time, and either 
“SET 1” (for original sample) or “SET 2” (for duplicate sample). 
5. Cap the labeled storage tubes and freeze the plasma samples immediately at approximately 
-20°C or lower. No more than 120 minutes will elapse between blood collection and freezing 
the plasma sample.
6. Keep samples frozen at approximately -20°C or lower until shipment site. 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.
Shipping of Plasma Samples
Site may adhere to the site’s SOPs on shipping samples if the SOP differs from the sample 
instructions provided.
Biological samples should be shipped on sufficient dry ice to prevent thawing during transit. 
Samples should be shipped to arrive at their destination during normal business hours (local time). 
It is recommended that samples be shipped on Monday, Tuesday or Wednesday and 2 days before 
a national holiday, in order to minimize the possibility of samples arriving at their destination on a 
weekend or holiday. For shipments outside these periods, it is recommended that a premium 
carrier who will replenish dry ice during shipment as necessary be used. Other shipping 
arrangements may be allowed with the agreement of the Sponsor. If duplicate samples are to be 
shipped, send SET 1 samples and await confirmation of arrival before shipping the duplicate SET 
2 samples.
Before shipping, make sure the sample tubes are tightly sealed. Separate each subject’s samples as 
follows:
1. Separate the duplicate SET 2 samples from the SET 1 samples.

2. Place SET 1 samples for each subject into zipper lock bag containing additional absorbent 
material.
3. Using a permanent marker, write the enrollment number, sample matrix (ie, plasma or urine), 
analyte (TAK-390MR), number of samples, and “SET 1” on each zipper lock bag.
4. 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.
5. An inventory of individual samples should accompany each shipment and should include the 
Sponsor’s name (Takeda), study drug (TAK-390MR), protocol number (TAK-390MR_106), 
investigator’s name, sample type (ie, plasma), subject’s enrollment number, 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 zipper lock 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.
6. For sample packing, use 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.
7. 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.
8. Mark the outside of shipping carton(s) with a tally number (eg, 1 of 5, 2 of 5).
9. Affix an address label to each shipping carton. Complete the address label with the following 
information:
Plasma Samples for TAK-390MR_106
10. Affix a carbon dioxide label on each carton, specifically:
Carbon Dioxide Solid UN-1845
Class 9 PKG GR III
Quantity _____________________

11. 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.
12. Obtain the airway bill number and a receipt of shipment from the carrier.
13. After shipping of the samples, contact the analytical site and CRO representative to notify 
them of next day delivery. When calling, provide the following information:
Name of courier or transport company
Time and date the shipment left the clinical site
Airway bill number
Instructions for processing and shipping of blood samples for genotyping analysis
