Overview of the study 
Study title: 
Phase-3 clinical study of duloxetine hydrochloride in children and adolescent 
patients with depressive disorder: An open-label extension study 
Study No.: 
1702A3632 
Development 
phase: 
3 
Primary objective: 
To evaluate the long-term safety of duloxetine in children and adolescent patients 
with depressive disorder. 
Secondary 
objectives: 
• 
To evaluate the long-term efficacy of duloxetine in children and adolescent 
patients with depressive disorder. 
• 
To evaluate the pharmacokinetics of duloxetine in Japanese children and 
adolescent patients with depressive disorder. 
- 
To compare the plasma duloxetine concentrations at steady state obtained 
at 5 time points (including at least one predose level [trough]) in children 
and adolescent patients with depressive disorder with those of adult 
patients with depressive disorder. 
- 
To examine the potential factors that affect the pharmacokinetic properties 
of duloxetine (e.g., age, body weight, and sex) and their effects in the 
population pharmacokinetics analysis. 
• 
To evaluate the relationship between duloxetine exposure at steady state and 
Children’s Depression Rating Scale-Revised (CDRS-R) total score, one of the 
efficacy endpoints. 
Study design: 
This study is a multicenter, open-label, uncontrolled, long-term treatment study in 
children and adolescent patients with depressive disorder. This study will include a 
total of 135 patients; consecutive subjects who have completed the preceding study 
“Phase-3 clinical study of duloxetine hydrochloride in children and adolescent 
patients with depressive disorder: Superiority study versus placebo” (Study No.: 
1701A3631) then wish to continue the study treatment will be enrolled, as well as 
additional subjects who have child and adolescent depressive disorder, with a target 
of 100 subjects completing a 1-year treatment.  
This study will consist of the following four periods (a total of 53 to 56 weeks): 
screening period (1 to 3 weeks), treatment period (50 weeks), tapering period (1 to 
2 weeks), and follow-up period (1 week). Note that consecutive subjects will 
undergo three periods (a total of 52 to 53 weeks), excluding the screening period. 
New subjects whose eligibility has been confirmed after obtaining informed consent 
will be pre-registered (Visit 1), and, after completion of the 1- to 3-week screening 
period, their eligibility will be confirmed again and they will be registered (Visit 2).

1.  Background information 
Depression is a psychiatric disorder, with the principal symptoms being depressive mood, and 
mood/affective disorders such as anxiety and irritation, and it is often associated with volitional and 
behavioral disorders, and also generalized symptoms such as sleep disorders, anorexia, and fatigue. The 
etiology and pathology of depression have not been fully elucidated (1), but one fundamental concept of 
the mechanism of onset of depression is the monoamine hypothesis, according to which deficiency of 
monoamines, such as serotonin and noradrenaline, which are neurotransmitters at cerebral nerve terminals, 
results in decreased synaptic transmission (2). 
Before 1980, very little attention was given to pediatric depression, and it was thought to be a very rare 
condition. However, when the operational diagnostic criteria in DSM Version 3 (DSM-III), published by 
the American Psychiatric Association in 1980, were applied, it was found that there are children with 
depressive symptoms just as there are adults, and it is now clear that pediatric depression patients are far 
more numerous than previously thought (3). Overseas epidemiological studies have shown that the 
frequency of initial depressive episodes increases rapidly from the age of 12, and from that age the 
incidence of depression is approximately the same as in adults (4, 5). In addition, although the symptoms 
of depression change with developmental stage, it has been reported that from the age of 10 they 
increasingly resemble those of adults (6). In recent years, considerable attention has been given to 
pediatric/adolescent depression in Japan, and the number of patients diagnosed has increased (7). The 
progression and prognosis of pediatric depression are not good, as, according to a prognostic survey of 65 
patients by Kovacs (1984), 92% showed recovery within 18 months after onset, but with 40% of these the 
condition recurred within 2 years after recovery, and with 70% it recurred within 5 years after onset (8, 9). 
According to Fombonne (2001), a 20-year outcome survey of 149 patients with depression onset before 
the age of 18 showed recurrence of major depression with 62.4% (10). In other words, pediatric depression 
is readily cured, but also recurs readily (11); it is a condition showing both high incidence and ready 
recurrence. In addition, it is considered that it results in considerable psychosocial dysfunction, and also 
has major effects on family members (3). For these reasons, as with adult depression, prompt and 
appropriate diagnosis and treatment are important for pediatric depression. However, it cannot really be 
said that appropriate, evidence-based drug therapy is currently in use (7). In Japan, clinical studies of 
children and adolescent depression have not shown any safe and effective antidepressants, and no drugs 
are currently indicated for pediatric depression. However, based on the results of overseas clinical studies, 
the package insert of escitalopram has no description of careful administration to patients aged 12 to 17. 
The latest version of Treatment Guideline II: Major Depressive Disorder, amended from the previous 
version (amended 2013) by the Japanese Society of Mood Disorders in July 2016 (7) includes a new section, 
titled “Pediatric/adolescent depression”, which is an area of ongoing research, and the unmet medical needs 
for pediatric/adolescent antidepressants are thus proposed. In the USA also, on the basis of observational 
research on and reanalysis of clinical studies on serotonin/noradrenaline reuptake inhibitors and selective 
serotonin reuptake inhibitors, several reports have suggested that the risks of not prescribing 
antidepressants to juveniles are higher than the risks of prescribing them. Therefore, in July 2016, the 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 17 - 
American Academy of Pediatrics amended its treatment guidance (Guidance for the Clinician in Rendering 
Pediatric Care) to recommend appropriate antidepressant treatment even for juveniles (12). 
Duloxetine is a compound that is classified as a serotonin/noradrenaline reuptake inhibitor and shows 
marked inhibition of both serotonin (5-HT) and noradrenaline reuptake. In Japan, after approval for 
treatment of depression and depressive state was achieved in January 2010, approval was achieved for the 
following indications: (i) pain associated with diabetic neuropathy; (ii) pain associated with fibromyalgia; 
(iii) pain associated with chronic low back pain; and (iv) pain associated with osteoarthritis. In worldwide 
terms, since approval for major depressive disorder was achieved in the USA in August 2004, it has been 
approved in more than 100 countries, including Japan, and is now in wide use. In addition, as of May 2017, 
in addition to major depressive disorder, it has been approved for numerous indications, including (i) pain 
associated with diabetic neuropathy; (ii) fibromyalgia; (iii) chronic musculoskeletal pain, including 
chronic low back pain and chronic osteoarthritis; (iv) stress urinary incontinence; and (v) generalized 
anxiety disorder. Most of the above indications are for adults, but in October 2014 generalized anxiety 
disorder was achieved as a pediatric indication in the USA. In addition, in March 2015 the Duloxetine 
Pediatric-Focused Safety Review (Cymbalta® [Duloxetine] Pediatric Advisory Committee Meeting) was 
held in the USA, no new safety-related concerns were identified, and the Food and Drug Administration 
(FDA)’s conclusion was that the usual safety monitoring should be continued (13). 
On the other hand, in the HMCK and HMCL studies, which were overseas, Phase-3, double-blind, parallel-
group, comparative studies with pediatric/adolescent major depressive disorder patients diagnosed on the 
basis of DSM Version 4 (amended version; DSM-IV-TR), although no particular safety-related problems 
were found, there were high placebo responses in both studies, and superiority over the placebo was not 
found with either duloxetine or the positive control, fluoxetine. However, on the basis of the results of a 
supplementary analysis performed before a Japanese study was planned, in a population of patients with 
treatment initiation at the age of ≥9 and depression onset at the age of ≥7, the changes in CDRS-R total 
scores in the duloxetine 30- and 60-mg groups were significantly higher than in the placebo group (in the 
HMCL study, this was the change at the final evaluation time-point, at week 10, by the LOCF method). In 
addition, as a tendency toward differences in placebo response between institutions was found, it is 
considered that performance of the study with a relatively small number of subjects, at an institution 
selected as having a low placebo response, is a method that is appropriate from the point of view of a 
clinical study, and that it should increase the probability of success. In addition, both the pediatric subjects 
enrolled in the study and their guardians are to be given basic psycho-education about treatment of 
depression, which will be systematic, and have the same contents, and this is expected to minimize the 
variation between subjects, thus increasing the detection power. At the same time, the psycho-education is 
to be provided consistently from the screening period, and subjects with high placebo response are to be 
excluded, thus reducing the mean placebo response. 
Under such background, the preceding study “Phase-3 clinical study of duloxetine hydrochloride in 
children and adolescent patients with depressive disorder: Superiority study versus placebo” (Study No.: 
1701A3631) will be conducted to evaluate the efficacy and safety of duloxetine in children and adolescent

- 18 - 
patients with depressive disorder. Additionally, an extended long-term treatment study is planned in 
participants of the preceding study and new patients in order to confirm the long-term safety and efficacy 
of duloxetine. 
The duloxetine package insert includes, as drug-class labeling, the following requirement to take care: 
“There have been reports of an increased risk for suicidal ideation and/or suicidal attempt in antidepressant-
treated patients aged 24 years or younger, so consideration should be given to the risk/benefit relationship 
when this drug is to be administered”. Therefore, the intention is to take great care during performance of 
this study with the followings. Sufficient warning, especially about suicide-related adverse events is to be 
given to the principal investigator or sub-investigator. In addition, information about adverse events, 
especially those relating to suicide, as well as the evaluation by C-SSRS is to be gathered, and the Safety 
Evaluation Committee is to assess them.

3.  Study plan 
3.1  Study design 
This study is a multicenter, open-label, uncontrolled, long-term treatment study in children and adolescent 
patients with depressive disorder. This study will include a total of 135 patients; consecutive subjects who 
have completed the preceding study then wish to continue the study treatment will be enrolled, as well as 
additional subjects who have child and adolescent depressive disorder, with a target of 100 subjects 
completing a 1-year treatment. 
As shown below, this study will consist of the following four periods (a total of 53 to 56 weeks): screening 
period (1 to 3 weeks), treatment period (50 weeks), tapering period (1 to 2 weeks), and follow-up period 
(1 week). Note that consecutive subjects will undergo three periods (a total of 52 to 53 weeks) excluding 
the screening period. 
Consecutive subjects will give consent to this study before completing the observation at Visit 9 in the 
preceding study, and, after completing the observation at Visit 9 in the preceding study and the eligibility 
of this study is confirmed, be enrolled to this study from Visit 2 (registration). 
• 
Screening period (for new subjects only): After obtaining informed consent, subjects for whom 
eligibility is confirmed will be pre-registered (at Visit 1) and the first session of psycho-education 
will be provided in addition to the subjects’ condition assessment. 
• 
Treatment period: Subjects for whom eligibility is confirmed will be registered (at Visit 2) and the 
study drug will be administered orally, once daily after breakfast, for 50 weeks. The administration 
of duloxetine will be initiated at 20 mg/day, then the dose will be increased to 40 mg/day from 1 
week after treatment initiation. From 2 weeks after treatment initiation, if there are no concerns 
about safety, the dose may be increased to 60 mg/day. Subsequently, until 50 weeks after treatment 
initiation, the dose may be increased to 40 mg/day or 60 mg/day as appropriate, depending on the 
symptoms. 
• 
Tapering period: In order to minimize the occurrence of adverse events due to discontinuation of 
administration, a 1- to 2-week tapering period is set for subjects who complete the treatment period, 
or who withdraw from it during the second week or later. Subjects whose duloxetine dose at 
discontinuation or completion of the treatment period is 60 mg/day will receive 40 mg/day for one 
week then 20 mg/day for one week. If the dose at discontinuation or completion is 40 mg/day, 20 
mg/day will be administered for one week. 
• 
Follow-up period: No study drugs will be administered during the 1-week follow-up period. This 
period is set to enable evaluation of any adverse events during the week after completion of study 
drug administration, irrespective of whether or not the dose was tapered. If administration is 
discontinued during the treatment period, and there is then no administration during the tapering 
period, a 1-week follow-up period will be set after administration discontinuation. 
 
The study design is shown in Fig. 3-1. The study schedule is shown in Appendix 1.

The principal investigator or sub-investigator will as far as possibly encourage subjects to complete the 
study, but subjects can withdraw for any reason. The principal investigator or sub-investigator will notify 
the sponsor about all discontinuations. If one or more of the following is applicable, the principal 
investigator or sub-investigator will discontinue study drug administration to the subject, and then 
discontinue the study. Note that the study will be considered completed when administrations and 
observations up to Visit 19 are completed. 
• 
The principal investigator or sub-investigator judges discontinuation to be necessary due to one or 
more serious or intolerable adverse events. 
• 
The principal investigator or sub-investigator judges that insufficient efficacy of the study drug has 
resulted in aggravation of the primary disease, making discontinuation necessary.

• 
It is judged that management of abnormal hepatic function test results is necessary, as is withdrawal 
on the basis of the discontinuation criteria (Appendix 2). 
• 
Discontinuation is judged by the principal investigator or sub-investigator to be necessary for any 
other reason. 
If a subject is withdrawn, the principal investigator will promptly report the withdrawal to the sponsor, and 
will as far as possible perform the assessments and tests for discontinuation of the treatment period or 
tapering period. Subjects withdrawn during the treatment period will be transferred to the tapering period. 
In the case of subjects withdrawn during the tapering period, the assessments for the follow-up period will 
be performed. All subjects withdrawn because of adverse events will be followed up until one of the 
following: (i) recovery from the adverse event to the state pertaining before administration initiation; (ii) 
the investigator or sub-investigator judges that the symptoms have stabilized or become chronic; and (iii) 
it is not possible to maintain communications with the subject. In addition, the date of completion or 
discontinuation of the treatment period or tapering period (as applicable), and the reasons for 
discontinuation (if applicable), will be recorded in the CRF.

measurement at Visit 9 in the preceding study may be used as a measurement at Visit 2 of this study. The 
principal investigator or sub-investigator will judge whether ECG results are normal or abnormal, and will 
record the date of ECG, the judgment, and any abnormal findings in the CRF. 
If there are abnormal findings, the principal investigator or sub-investigator will judge whether the 
abnormal change from baseline (i.e., Visit 1 for new subjects or Visit 2 for consecutive subjects) is 
clinically significant (refer to Section 7.7.7.7 ), and will record any changes judged to be clinically 
significant as adverse events.

7.7.6.1  Laboratory test items 
At Visits 1 (or Visit 2 for consecutive subjects), 5, 8, 11, 14, and 18 (or at discontinuation of the tapering 
period; if not transferred to the tapering period, at completion or discontinuation [Visit 17] of the treatment 
period), blood samples will be collected for laboratory tests, the volumes being 2 mL for hematology tests, 
and 8 mL and 5 mL for blood chemistry tests, at Visit 1 and other visits, respectively; and urine samples 
will also be collected. The samples will then be sent to the clinical laboratory facility specified in Section 
7.7.6.2 . Details of the collection, handling, storage, and shipment of samples are stipulated in a separate 
document. For new subjects, blood samples and urine samples at Visit 1 will be collected after obtaining 
informed consent, between 3 weeks before the initial administration of the study drug and Visit 2. For 
consecutive subjects, a measurement at Visit 9 in the preceding study may be used as a measurement at 
Visit 2 of this study. Both new subjects and consecutive subjects will be registered after the latest 
measurements at Visit 2 are confirmed. 
The principal investigator or sub-investigator will judge whether the abnormal change from baseline (i.e., 
Visit 1 for new subjects or Visit 2 for consecutive subjects) is clinically significant (refer to Section 7.7.7.7 ), 
and will record any changes judged to be clinically significant as adverse events. The sample collection 
dates will be recorded in the CRF for each sample type (blood or urine).

7.7.7  Evaluation of adverse events 
7.7.7.1  Evaluation methods for adverse events 
An adverse event is any unfavorable medical event suffered by someone administered a pharmaceutical 
product (including a study drug) and does not necessarily have a causal relationship with the relevant 
pharmaceutical product. In other words, an adverse event is any unfavorable and/or unexpected sign 
(including abnormal laboratory test result), symptom, or disease associated with the administration of a 
drug, irrespective of any causal relationship with that drug. Surgery that was already planned is not 
considered to be an adverse event, unless it leads to exacerbation of an existing disease, and is therefore 
not considered to be a serious adverse event even if it necessitates hospitalization. However, if an additional 
surgery is performed in connection with the planned surgery, this is taken to be an adverse event, and to 
be a serious adverse event if prolongation of hospitalization is required, or if any other criterion for being 
a serious adverse event is met. Hospitalization or prolongation of hospitalization for reasons other than 
adverse events is not considered to constitute a serious adverse event. 
The presence or absence of an adverse event will be confirmed on the basis of the subject’s spontaneous 
complaint, non-inductive questions, examination, C-SSRS, blood pressure, pulse rate, body weight, and 
ECG or laboratory test results. Adverse events include new onset of an event, increase in the severity or 
frequency of an event since administration initiation, and diagnostic abnormality, including abnormal 
laboratory test results. A symptom recorded as a medical history at study initiation will be handled as an 
adverse event only when symptoms are aggravated. In addition, loss of efficacy, and changes in the primary 
disease (depression) or scores for any of the CDRS-R items, will not be handled as adverse events in this 
study, unless judged to be serious adverse events. 
The principal investigator or sub-investigator will evaluate adverse events. The principal investigator or 
sub-investigator will carefully investigate each adverse event, and record in the CRF the date of onset, 
time of onset, date of cessation (if the outcome is recovery or death), severity, seriousness (including the 
reason for judging seriousness), causal relationship with the study drug, actions taken for the adverse event, 
and outcome of the adverse event.

7.7.7.2  Assessment period 
Adverse events occurring between obtaining the legal representative’s informed consent (for new subjects) 
or initiation of study drug administration in this study (for consecutive subjects) and 7 days after the final 
administration of study drug (the follow-up period) as well as adverse events consecutive from the 
preceding study at the initiation of study drug administration in this study (only if applicable) will be 
assessed. For consecutive subjects, adverse events that occurred between obtaining informed consent for 
this study and initiation of study drug administration in this study will be assessed in the preceding study. 
In the case of withdrawn subjects, the principal investigator or sub-investigator will assess adverse events 
up to 7 days after final administration of the study drug. Appropriate follow-up will be continued until one 
of the following, and the outcome will be determined on that basis: (i) the relevant adverse event recovers 
to the pre-administration state (if consecutive from the preceding study, it should be recovered to the pre-
administration of the preceding study); (ii) the subject’s condition stabilizes or becomes chronic; (iii) the 
subject is lost to follow-up; or (iv) the principal investigator or sub-investigator judges further assessment 
to be unnecessary. In addition, if the subject stops visiting hospital during the study, he/she will be followed 
up by an appropriate method such as by telephone, and the findings will be entered in the CRF. 
If the above adverse event follow-up has to be continued for 28 days or more after completion of 
administration, the outcome at the earliest date after 28 days after completion of administration will be 
recorded in the CRF. 
 
7.7.7.3  Severity 
The principal investigator or sub-investigator will judge the severity of adverse events in accordance with 
the below definitions. The highest severity of each event during its period of occurrence will be recorded 
as the severity in the CRF. 
• 
Mild:  
Signs or symptoms are found, but activities of daily life are not disturbed. 
• 
Moderate:  
Activities of daily life are disturbed due to discomfort, and/or abnormality is 
clinically demonstrated. 
• 
Severe:  
Activities of daily life are impossible, and/or major clinical effects are 
demonstrated. 
 
7.7.7.4  Causal relationship with study drug 
The principal investigator or sub-investigator will judge the causal relationship with the study drug in 
accordance with the following criteria: 
• 
Not related:  
The adverse event can be clearly explained by a factor other than the 
study drug, and/or there is no valid chronological relationship between 
the study drug and the adverse event. 
• 
Possibly related:  
The adverse event may have been caused by a factor other than the 
study drug, but a causal relationship with the study drug cannot be 
ruled out. 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 41 - 
• 
Probably related:  
It is unlikely that the adverse event was caused by a factor other than 
the study drug. 
• 
Related:  
There is a valid chronological relationship between administration of 
the study drug and onset of the adverse event, and the event cannot be 
explained by a factor other than the study drug 
 
Adverse events judged to be “Possibly related”, “Probably related” or “Related” are taken to be adverse 
drug reactions. 
 
7.7.7.5  Predictable adverse drug reactions 
Adverse drug reactions listed in the most recent investigator’s brochure for duloxetine, or in any reports 
about adverse drug reactions submitted separately to the IRB, study site, or the principal investigator, are 
taken to be predictable adverse drug reactions. 
 
7.7.7.6  Adverse events of special concern 
7.7.7.6.1  Suicide-related adverse events 
The duloxetine package insert, includes, as drug-class labeling, the following requirement to take great 
care: “There have been reports of increases in the risks of suicidal ideation and suicidal planning in patients 
aged under 24 administered antidepressants, so consideration should be given to the risk/benefit 
relationship when this drug is to be administered”. Therefore, the principal investigator or sub-investigator 
will evaluate any suicidal thinking using the C-SSRS questionnaire, as detailed in Section 7.7.2 , and will 
record any suicide-related adverse events. 
The principal investigator or sub-investigator will perform sufficient monitoring of subjects who suffer 
from adverse events that are clearly or possibly suicide-related. 
If a subject suffers a suicide-related adverse event, and/or if requested by the sponsor, the principal 
investigator will report the details of the relevant adverse event to the sponsor, by fax, email or telephone, 
or orally. After the sponsor has received the relevant information, he/she will promptly request the Safety 
Evaluation Committee to perform a review. If necessary, the sponsor can also request the principal 
investigator to provide additional information. 
 
7.7.7.7  Adverse events such as laboratory test results 
The principal investigator or sub-investigator will judge whether or not any changes from the baseline by 
laboratory test results (hematology, blood chemistry, and urinalysis) and abnormalities in other safety 
endpoints (e.g. examination findings, body weight, blood pressure, pulse rate, ECG findings) are clinically 
significant. Laboratory test results that deviate from the reference range will be handled as abnormal values. 
If a baseline value is abnormal, but worsens after study initiation, the principal investigator or sub-
investigator will judge whether or not this is clinically significant. Events judged by the principal 
investigator or sub-investigator to be clinically significant will be recorded as adverse events. When an 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 42 - 
abnormal test result is accompanied by disease or other toxicity, the disease name and/or details of toxicity 
will be reported as an adverse event. 
An event will be considered clinically significant if one or more of the following criteria is met, and 
judgment about clinical significance in other situations will be at the discretion of the principal investigator 
or sub-investigator: 
• 
The criterion for a serious adverse event is met (refer to Section 7.7.7.8 ). 
• 
Study drug discontinuation or dose reduction is required. 
• 
Drug administration or another procedure is required for treatment. 
• 
An additional test or other medical procedure is required. 
• 
Management of abnormal hepatic function test results is necessary, and the discontinuation criteria 
(Appendix 2) are met. 
If management of abnormal hepatic function test results is necessary, and the discontinuation criteria 
(Appendix 2) are met, evaluation and additional assessment will be performed, and records will be made 
in the follow-up assessment form for abnormal hepatic function. 
 
7.7.7.8  Serious adverse events 
7.7.7.8.1  Definition 
Of the adverse events observed after study initiation, an adverse event meeting one or more of the 
following criteria will be handled as a serious adverse event: 
• 
Leading to death. 
• 
Life-threatening. 
• 
Requiring hospitalization or prolongation of hospitalization. 
• 
Leading to permanent and/or significant disability or dysfunction (according to the opinion of the 
reporting physician). 
• 
Leading to congenital anomaly. 
• 
Other medically major event. 
If an adverse event exposes a subject to danger, or requires medical procedures to prevent one of the results 
defined above, even if the event does not lead to death, is not life-threatening, and does not require 
hospitalization, it will be handled as a serious adverse event on the basis of appropriate medical judgment. 
For example, bronchial asthma which requires intensive therapy at emergency department, etc., vascular 
disorder or convulsion not requiring hospitalization, drug dependency or abuse are included. In addition, 
all events meeting the below criterion are taken to be serious adverse events. The principal investigator or 
sub-investigator will judge the seriousness of adverse events. 
− 
AST and/or ALT >3 times the upper limit of the respective reference values, and total bilirubin 
>2 times the upper limit of the reference values. 
 
7.7.7.8.2  Reports of serious adverse events 
The principal investigator will report the details of all serious adverse events to the sponsor, using the 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 43 - 
serious adverse event report form, within 24 hours after the relevant events are judged to be serious. All 
serious adverse events will be reported, irrespective of the causal relationship with the study drug. The 
sponsor can also request additional information about serious adverse events. 
As far as possible, the principal investigator will report all serious adverse events using the diagnostic 
names. If the diagnostic name has not been fixed at the time of reporting, the report will state the individual 
signs and symptoms. 
 
Serious adverse event reports and contact person for 
reporting 
 
 
 
 
 
 
 
 
 
 
If the sponsor judges follow-up to be necessary, the principal investigator will report to the above contact 
person by fax or email, using a serious adverse event form, and will provide any new information to the 
sponsor. The principal investigator will evaluate photocopies of relevant documents, such as discharge 
summaries, medical records from other departments and institutions, and autopsy reports, and will include 
any relevant information in a supplementary serious adverse event report. The sponsor can also request 
photocopies of such reports. 
The principal investigator will establish appropriate measures for medical treatment of serious adverse 
events, on the basis of medical judgment. Measures taken with serious adverse events, and their results, 
will be recorded. The principal investigator will establish the necessary measures, and will also elucidate 
the causes of serious adverse events as far as possible. 
If a serious adverse event during or after the assessment period stipulated in Section 7.7.7.2 is judged by 
the principal investigator to have a causal relationship with study drug, he will report it to the sponsor. 
The principal investigator will also report all serious adverse events to the IRB in accordance with the 
regulatory requirements. The sponsor will report all reported serious adverse events to the regulatory 
authority, in accordance with the regulatory requirements. 
 
7.7.7.9  Abuse, misuse, overdose, and medication error (special situations) 
In the event of abuse, misuse, overdose, or medication error associated with the study drug (special 
situations), as defined below, the principal investigator will promptly report it to the sponsor by fax or 
email, using the form stipulated by the sponsor (Special Situation Report Form). The principal investigator 
will also submit reports to the sponsor about any serious adverse events associated with the special 
situation. 
• 
Abuse: Intentional overdose of the study drug, associated with adverse physical or mental effects, 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 44 - 
irrespective of whether this is continuous or sporadic. 
• 
Misuse: Inappropriate use of the study drug at doses other than those instructed or on the label, 
intentionally by the subject. 
• 
Overdose: Accidental or intentional use of the study drug at a dose exceeding that prescribed. 
• 
Medication error: An accidental medication error, including cases that have been prevented from 
occurring, during the process of prescription, dispensing or administration. A medication error due 
to the subject forgetting to take one or more doses is not reportable. 
 
7.7.7.10  Pregnancy 
The principal investigator or sub-investigator will instruct female subjects that, if they become pregnant 
during the study, they must stop taking the study drug, and immediately inform the principal investigator 
or sub-investigator. If a subject is found to be pregnant, the principal investigator or sub-investigator will 
withdraw her form the study. Information about the pregnancy will be reported to the sponsor as detailed 
below. 
For all pregnancies that occur between initiation of study drug administration and completion of the follow-
up period, the principal investigator will send a pregnancy follow-up report to the sponsor by fax or email 
within 24 hours after the pregnancy comes to light. Pregnancy complications and terminations for medical 
reasons will be reported appropriately, as adverse events or serious adverse events. Miscarriages will be 
reported as serious adverse events. In addition, pregnancies will be followed, and pregnancy follow-up 
reports will be submitted to the sponsor by fax or email. Even after completion of the follow-up period, if 
a pregnancy comes to light within 1 month after the final study drug administration, the study site will 
report it to the sponsor. At completion of pregnancy, by birth, miscarriage or termination, the outcome will 
be reported to the sponsor. 
 
7.7.7.11  Adverse events during study drug administration 
Adverse events with onset after the initial study drug administration are taken to be treatment-emergent 
adverse events (TEAE). For consecutive subjects, of adverse events consecutive from the preceding study 
at initiation of study drug administration in this study, adverse events that started after initiation of study 
drug administration in the preceding study are also taken to be TEAEs of this study. 
 
7.8  Appropriateness of test items 
Efficacy endpoints chosen in this study are similar to those in the preceding study in order to study and 
examine various aspects of long-term efficacy. 
Safety endpoints chosen in this study are also similar to that in the preceding study. 
 
7.9  Permitted range of test times 
Examination, observation and tests will be performed in accordance with Appendix 1. If performance at 
the date and time shown in Appendix 1 is impossible, for unavoidable reasons, performance within the 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018

8.  Statistical analysis 
8.1  Statistical analysis methods 
The sponsor will commission a contract organization to perform the statistical analysis. The sponsor will 
perform the pharmacokinetic analysis. The details of the analysis will be stipulated in the “Statistical 
analysis plan” and “Pharmacokinetic analysis plan”, which will be prepared on the basis of this section. 
When any change is made to the analysis planned in the protocol, reason for a change will be specified in 
the statistical analysis plan or pharmacokinetic analysis plan without fail. 
Number of subjects, arithmetic mean, standard deviation, minimum, median, and maximum will be 
calculated as summary statistics for the items measured by continuous data in principle. Number of 
subjects and proportion of each category will be calculated as summary statistics for the items measured 
by discrete value. 
Level of significance at 0.05 (two-sided) will be used for statistical tests in this study unless otherwise 
specified. There will be no multiplicity adjustment for the statistical tests. 
SAS of Version 9.2 or higher will be used for all analyses and for creation of tables. 
 
8.2  Target number of subjects 
The target number of subjects is set as at least 100 subjects to collect data from, who receive duloxetine 
for one year. Assuming that 25% of subjects dropout from this study, the target total number of registered 
subjects is 135, including consecutive subjects and new subjects. Blood samples for plasma drug 
concentration measurements will be collected five times for each subject to evaluate the pharmacokinetics 
in Japanese children and adolescent patients with depressive disorder. 
 
8.3  Analysis sets 
The following analysis sets are defined: 
(1) 
Full-analysis set (FAS)  
This comprises all subjects to whom the study drug has been administered at least once, and with whom 
the CDRS-R total score has been determined at baseline and at least once after initiation of study drug 
administration. 
(2) 
Safety-analysis set 
This comprises all subjects to whom the study drug is administered at least once.  
(3) 
Pharmacokinetic analysis set 
This comprises all subjects to whom the study drug is administered at least once and the plasma duloxetine 
concentration is measured at least once. The pharmacokinetic analysis set will be used for preparing and 
summarizing the list of drug concentrations. 
 
8.4  Handling of missing data 
In principle, missing data will not be imputed. However, if missing data is imputed for analysis at the final 
evaluation time point, LOCF may be used.

8.5  Subject characteristics 
Of the subjects registered, the number and proportion who complete the study, and the number and 
proportion withdrawn will be summarized. In addition, the reasons for withdrawal will be summarized. 
The number and proportion of subjects included in each analysis set will also be shown. 
 
8.6  Demographic and baseline characteristics 
The summary statistics will be used to summarize the demographic and baseline characteristics of the 
safety analysis set. 
 
8.7  Study drug administration period, dosage, and treatment compliance 
The study drug administration period, administration rate, and total dose will be summarized on the safety 
analysis set.  
 
8.8  Prior treatment 
Drugs used in prior treatment will be coded for using the WHO Drug Dictionary. With the safety analysis 
set, the subjects who received prior treatment will be tabulated. 
 
8.9  Concomitant treatment 
Drugs used in concomitant treatment will be coded for using the WHO Drug Dictionary. For the safety 
analysis set, the subjects who receive concomitant therapy will be tabulated. 
 
8.10  Analysis of efficacy 
The summary statistics will be calculated using the FAS for the observed efficacy endpoints (CDRS-R 
total score and CGI-S) and their changes from baseline at each time-point after study drug administration. 
The baseline for each endpoint is defined as the subject’s initiation of this study (Visit 2). Changes from 
the start of the preceding study will be summarized similarly by treatment group in the preceding study. 
 
8.11  Safety analysis 
Safety analysis will be conducted on the safety analysis sets. 
 
8.11.1  Adverse events 
Adverse events will be classified by system organ class and preferred term, in accordance with MedDRA. 
Of the adverse events reported using CRFs, TEAEs will be used for safety analysis. TEAEs are defined in 
Section 7.7.7.11 . 
The number of subjects suffering TEAEs, and the numbers suffering death, other serious TEAEs, TEAEs 
leading to discontinuation of administration, and TEAEs leading to dose reduction will be determined. The 
TEAE rate and 95% confidence interval will be calculated by the Clopper-Pearson method. The number 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 48 - 
of adverse events will also be included. Adverse drug reactions will be summarized in the same manner as 
TEAEs. Adverse drug reactions are defined in Section 7.7.7.4 . 
As summarization of TEAEs by system organ class and preferred term, the number and proportion of 
subjects suffering these events will be shown. In addition, TEAEs will be summarized by severity, onset 
timing, and outcome. Adverse drug reactions will be summarized similarly. 
 
8.11.2  Blood pressure, pulse rate, and body weight 
Summary statistics will be calculated for the measurements and change from baseline at each time-point. 
The baseline is defined as the subject’s initiation of this study (Visit 2). 
 
8.11.3  Laboratory test results 
Summary statistics will be calculated for the measurements and change from baseline at each time-point. 
The baseline is defined as Visit 1 for new subjects or Visit 2 for consecutive subjects. 
The category distribution of the qualitative laboratory test data at each time-point will be summarized. 
 
8.11.4  ECG 
The distribution of ECG findings (normal or abnormal) will be summarized for observation time-point. 
 
8.11.5  Columbia Suicide Severity Rating Scale (C-SSRS) 
The distribution of the presence or absence of suicidal ideation and suicidal behavior will be summarized 
for observation time-point. 
 
8.12  Pharmacokinetic analysis 
Plasma duloxetine concentrations and time from the last administration will be listed for each subject. 
Trough plasma concentrations, which are 18 to 30 hours after the last administration of duloxetine, for 
each subject will be collected and summarized for each dose group by the number of subjects with 
measurements, arithmetic mean (Mean), standard deviation (SD), coefficient of variation (CV% = 
SD/Mean × 100), median, minimum (Min), and maximum (Max). The plasma concentration below 
quantifiable limit will be substituted with 0. The plasma duloxetine concentrations at steady state from 
children and adolescent patients with depressive disorder will be compared with those of adult patients 
with depressive disorder. The relationship between the trough concentration of duloxetine and CDRS-R 
total score will be displayed in a graph. 
Data considered by the pharmacokinetic analysts to be clearly inappropriate to include in the analysis will 
be excluded from the analysis. If excluded, the reason for exclusion shall be described in the clinical study 
report. 
The population pharmacokinetic analysis will be conducted using a nonlinear mixed effect model, with 
NONMEM version 7.3 or higher. The report of population pharmacokinetic analysis will be prepared 
separately.

- 52 - 
relating to subject recruitment (when applicable), other documents provided to subjects, the investigator’s 
brochure, safety information, and annual reports of study performance (when applicable), as submitted by 
the principal investigator or sponsor. The IRB will be established on the basis of the GCP and various 
regulations. This study will be initiated after the principal investigator has obtained written approval by 
the IRB. 
Revision of the protocol should be deliberated as done for the initial deliberation. The principal investigator 
will submit all periodic reports and updated information upon request by the IRB. The principal 
investigator will report all the applicable adverse events to the IRB. 
 
9.3  Ethics 
The clinical study will be performed in accordance with the appropriate regulatory requirements and the 
protocol approved by the IRB, and in compliance with the latest GCP, all appropriate requirements for 
protection of subjects’ confidentiality, and ethical principles based on the Declaration of Helsinki. 
 
9.4  Providing information to patients and obtaining informed consent 
After accepting the sponsor’s proposal about the explanatory documents and informed consent form, or 
assent document, in accordance with GCP and the regulatory requirements, the principal investigator will 
prepare the explanatory documents and informed consent form, or assent document. The sponsor must 
agree with the revisions pointed out by the principal investigator in relation to the explanatory documents 
and informed consent form, or assent document, before submitting these documents to the IRB. The 
principal investigator must provide the sponsor with the explanatory documents and informed consent 
form, or assent document, after the documents have been appropriately reviewed and approved by the IRB. 
The principal investigator or sub-investigator will use the explanatory documents and informed consent 
form, or assent document, approved by the IRB to explain the quality, purpose, methods, foreseeable 
benefits, and potential risks to subjects before study participation, using readily understandable vocabulary. 
The method for obtaining written consent or assent should be in accordance with the GCP and appropriate 
regulatory requirements. 
 
9.5  Protection of subjects’ confidentiality 
Laws about appropriate data privacy protection must be complied with in relation to subjects’ personal 
information. CRFs, study drug management table, reports, letters, etc. should be identified by subject code 
to protect the personal information of subjects. The principal investigator will permit access to all source 
documents for monitors of the sponsor, auditors, and regulatory authority to confirm data of the CRF and 
verify procedures of data collection. However, personal information of subjects will be protected within 
the scope of appropriate laws and regulations. The principal investigator and sponsor must ensure that 
handling of confidential information is in accordance with any local regulatory requirements. If there is 
potential for anonymized subjects’ information to be used, made public, or transferred, appropriate consent 
or approval must be obtained. 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 53 - 
The information of subjects will be identified by subject ID code during the study and coded information 
will be recorded in the CRF. Personal information of subjects will be protected even when a subject must 
be identified for reasons such as safe conduct of a clinical study or instructions of regulatory authority. 
 
9.6  Monitoring 
The sponsor and contract monitoring organization will perform monitoring to ensure that the study is 
performed in compliance with the GCP requirements and the protocol. Monitoring will be performed by 
the sponsor or by monitors who are representatives of the contract monitoring organization, by means of 
on-site monitoring, at the appropriate frequency, and with frequent communication by e-mail, mail, 
telephone, or fax. Monitors will check the data recorded in the CRF; verify the items recorded in the CRF 
by direct access to source documents; collect information on the safety and efficacy of subjects; perform 
inspections to ensure that the quantity of unused study drug is accurate; and confirm that the source 
documents and essential documents have been stored. 
 
9.7  Case report forms and source documents 
9.7.1  Case Report forms 
The sponsor will provide the CRF. The CRF will be prepared using an EDC system. A CRF will be 
prepared for each new subject who has signed informed consent or for each consecutive subject who has 
registered to this study, and subjects’ demographic information stipulated in the protocol and data relating 
to the study will be recorded. Subjects’ data relating to the study will be recorded in the source documents, 
and then promptly recorded in the CRF in accordance with the procedures relating to the CRF. The 
principal investigator or sub-investigator, and other study collaborators designated in writing, will make 
entries in the CRF. 
If the sponsor has uncertainties about data from a study site, either the data in the CRF will be revised in 
accordance with the appropriate procedures, or a response to the question will be recorded. The principal 
investigator will ensure that the data recorded in CRF are accurate, complete, and legible and that the 
timing of submission is appropriate. The principal investigator will sign CRF to verify completeness of the 
recorded data. 
The sponsor will obtain in writing a list of site reference values for all laboratory test items before study 
initiation. When the site reference values are changed after study initiation, the list will be obtained in 
writing. If all or some tests are performed at a central laboratory, reference values will be obtained for all 
items measured by that laboratory. 
 
9.7.2  Source documents and raw data 
Source documents are the basic materials for data recorded in the CRF. Participation of subjects in the 
study, details and date of study performance, adverse events, and the condition of subjects will be recorded. 
However, for the following types of data, the data recorded in the CRFs may be used as raw data: 
Reasons for use of prior and concomitant treatment. 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 54 - 
Adverse events: severity, seriousness, and causal relationships with the study drug 
Comments recorded in CRFs. 
In addition, for data managed solely with CRFs (calculated automatically by the EDC), there is the 
following item: 
Age at the time of obtaining informed consent (new subjects only) 
Age at the time of obtaining assent (new subjects only) 
CDRS-R total score. 
 
The principal investigator will store source documents, such as laboratory test reports, and detailed subjects’ 
medical history and medical records. All source documents should be made available for direct access by 
monitors, auditors, and IRB and inspection by regulatory authorities. Therefore, the principal investigator, 
sub-investigator, or study collaborators must make arrangements enabling appropriate direct access. The 
sponsor and study site personnel will ascertain the source documents in which information required for 
completing CRFs is recorded, and where they are stored. In the case of storage by electronic recording, 
the access method for verification must be stipulated in a document stipulated by the study site. 
 
9.7.3  External data 
The following data will be reported separately from CRFs: 
• 
Plasma concentrations of duloxetine (measured at 
 
according to the separately prepared procedures) 
• 
Results of pharmacokinetic analysis 
• 
Laboratory test results 
 
9.8  Committees, meetings, etc. 
9.8.1  Case review committee 
Before the database lock, at a case review meeting, the sponsor, together with a medical expert, will check 
all data for all subjects recorded in CRFs. The subjects to be included in the analysis set will be decided 
upon on the basis of the outcome of the case review meeting and the definition of the analysis set in the 
protocol. Appropriateness of medical judgment of the principal investigator for the significant data 
affecting the safety or efficacy endpoint will also be evaluated during a case review meeting. 
 
9.8.2  Safety monitoring committee 
Depending upon the sponsor’s requirements, reported interim safety data will be evaluated, and the sponsor 
will be notified as to whether the study should be continued, modified or discontinued. The evaluation will 
be performed in accordance with the Safety Monitoring Committee’s standard operating procedures, which 
are set separately.

9.9  Study discontinuation or suspension 
9.9.1  Discontinuation or suspension of entire study 
The sponsor may discontinue or suspend the study when one or more of the following conditions is 
applicable: 
• 
Ensuring the safety of the study is difficult, for reasons such as multiple occurrence of serious 
adverse drug reactions. 
• 
It is not considered possible to achieve the study objectives, for reasons such as not being able to 
enroll a sufficient number of subjects. 
 
When disconsecutive or suspending the study, the sponsor must report promptly to the principal 
investigator. The principal investigator or sub-investigator must promptly explain about study 
discontinuation or suspension to the participating subjects, and transfer them to other appropriate treatment. 
Discontinuation criteria for each subject are shown in Section 4.5 . 
 
9.9.2  Discontinuation or suspension of study at each study site 
When ensuring the safety of the study is difficult, for reasons such as multiple occurrence of serious 
adverse drug reactions, the principal investigator may discontinue or suspend the study at the relevant 
study site after obtaining approval by the sponsor. If a major deviation from the protocol (including other 
procedures) and/or the GCP occurs, and is not resolved, the sponsor may request the principal investigator 
to discontinue or suspend the study at the relevant study site. 
If the study is discontinued or suspended, the principal investigator or sub-investigator must promptly 
explain about the discontinuation or suspension to the participating subjects and the IRB, and transfer the 
subjects to other appropriate treatment. 
 
9.10  Modifications to and deviations from the protocol 
The principal investigator will perform the study in accordance with the study protocol approved by the 
IRB and regulatory authority, and provided by the sponsor. Protocol amendments require agreement by the 
principal investigator and sponsor. For any protocol amendment, written approval must be obtained from 
the IRB beforehand, unless such amendments are medically essential for avoiding immediate risk to the 
subject. 
The principal investigator or sub-investigator must record deviations from the protocol and the reasons for 
these. In the event of an amendment to or deviation from the protocol in order to avoid immediate risk to 
the subject, the principal investigator must immediately submit a record of the deviation or amendment to 
the sponsor, study site, and IRB, and promptly obtain approval by the IRB. After obtaining approval by 
the IRB, the principal investigator will obtain written agreement by the sponsor, via the study site. 
If deviation from the protocol is required as an emergency, in a medically unavoidable situation, such as 
in order to avoid immediate risk to the subject, the principal investigator will contact the sponsor in 
advance wherever possible to discuss how this should be handled. All deviations from the protocol should 

 
 
 
LY248686; Shionogi & Co., Ltd. 
Protocol: 1702A3632; August 8, 2018 
- 56 - 
be recorded in the source documents. 
 
9.11  Data management 
The sponsor will commission data management tasks to a contract data management organization. Details 
of data management tasks will be defined in a separately specified procedure. 
 
9.12  Storage of records 
Study-related documents must be stored in accordance with the GCP and regulatory requirements. The 
principal investigator and study site must take measures to prevent accidental or premature disposal of the 
documents. When manufacture and marketing of the study drug has been approved, the sponsor will 
promptly report this in writing to the director of the study site. 
The duration of storage of records will be until the later of the following: 
• 
Three years after the date of achieving study drug marketing approval or after the decision to 
discontinue study drug development. 
• 
Three years after study discontinuation or completion. 
The above period of storage can be extended if necessary, as agreed upon with the sponsor. If the principal 
investigator cannot be responsible for storage of study-related records, this responsibility will be 
transferred to an appropriate successor. 
 
9.13  Study quality control and quality assurance 
The sponsor will define the procedures for quality control and quality assurance in the standard operation 
procedures in order to ensure that the study is performed, and that data, documents and reports are prepared 
in accordance with the protocol, GCP, and appropriate regulatory requirements. This study will be 
performed in accordance with ethical principles based on the Declaration of Helsinki, GCP, and other 
appropriate regulatory requirements. 
The sponsor will hold explanatory meetings with the principal investigator and each study site before study 
initiation, and will provide education and training as required for study performance. 
 
9.14  Decisions relating to publication 
All information about duloxetine provided by the sponsor to the principal investigator is confidential 
information, and must not be disclosed to any third party. The principal investigator must not use this 
information for purposes other than the study without obtaining the consent of the sponsor. All the 
information obtained during the study should be provided to the sponsor. The information obtained during 
the study will be used for development of duloxetine and will be disclosed to the regulatory authority, other 
principal investigators, joint development company, and consulting company, etc. as necessary. The 
sponsor possesses the right to all data. Approval of the sponsor should be obtained before making public 
the information obtained in this study. 
Overview of this protocol is made available on the clinical study registry site.

Appendix 2: Management of abnormal hepatic function test results, and 
discontinuation criteria 
In order to ensure subjects’ safety , as well as to evaluate the causes of any hepatic dysfunction found, 
management on the basis of abnormal hepatic function test results, and the discontinuation criteria, are 
defined, on the basis of the FDA’s July 2009 guidance (Guidance for Industry Drug-Induced Liver Injury: 
Premarketing Clinical Evaluation). 
 
(1) 
Hepatic dysfunction criteria 
The principal investigator or sub-investigator confirms whether or not the subject’s laboratory test results 
meet any of the following criteria: 
a. AST and/or ALT >5 times the upper limit of normal (ULN). 
b. AST and/or ALT >3 times the upper limit of normal (ULN), and total bilirubin >2 times the upper 
limit of normal (ULN). 
c. AST and/or ALT >3 times the upper limit of normal (ULN), and signs and/or symptoms consistent 
with hepatitis or hypersensitivity (e.g. fatigue, nausea, vomiting, right upper abdominal pain or 
tenderness, jaundice, fever, rash, eosinophil increase by more than 5%). 
 
(2) 
Principal investigator’s actions 
If one or more of the above hepatic dysfunction criteria is met, the principal investigator or sub-investigator 
will act as follows: 
• 
Immediately ensure that the subject stops taking the study drug. 
• 
If possible, have the subject visit hospital within 72 hours after the abnormalities are first found, to 
repeat the hepatic function tests for a supplementary evaluation of hepatic function. 
• 
Until the hepatic function test result (ALT, AST, ALP, and total bilirubin) abnormalities cease, 
stabilize, or return to within the reference range or to the baseline, the subject’s progression is 
observed two to three times per week, if possible. 
• 
Report to the sponsor using the hepatic dysfunction follow-up assessment form, within 72 hours 
after the relevant abnormalities coming to the principal investigator’s attention. 
• 
Look into the option of consulting a hepatologist or other specialist. 
• 
Look into the option of performing hepatic imaging, such as ultrasonography, magnetic resonance 
imaging, or computed tomography. 
• 
Report all events that meet criterion b (above) as serious adverse events. 
 
(3) 
Follow-up assessment 
If one or more of the above hepatic dysfunction criteria is met, items including the following will be 
assessed at the time of the follow-up assessment visit, and the results will be entered in the hepatic 
dysfunction follow-up assessment form: 
•
