Study Methodology
This is an interventional, multi-national, multi-site, randomized, parallel-group, placebo-controlled, 
relapse-prevention study in paediatric patients with MDD from 7 to 11 years of age. 
The study consists of a 12-week, open-label, flexible-dose treatment period with vortioxetine followed by a 
26-week, randomized, double-blind, fixed-dose, placebo-controlled relapse-prevention period.
The study population will include de novo patients as well as rollover patients from other paediatric 
vortioxetine studies (Studies 12709A and 12712A), who, in the investigator’s opinion, could benefit from 
continued treatment with vortioxetine.
  De novo patients 
Patients meeting eligibility criteria for de novo patients will be enrolled in the 12-week, open-label, 
flexible-dose treatment period.
  Rollover patients from Study 12709A (enrolled to the open-label period)
Patients may participate in the present study after completion of the randomized, 8-week, double-blind, 
placebo-controlled treatment period of Study 12709A. 
Eligible patients will be enrolled in the 12-week, open-label, flexible-dose treatment period.
The Baseline Visit of this study (Study 13546A) will take place at the same visit as Visit 12 (Completion 
Visit) of Study 12709A. Participation in Study 12709A is considered completed when all assessments 
required at Visit 12 are completed.
  Rollover patients (remitters) from Study 12712A (randomized to the double-blind period)
Patients who have received 8 to 12 weeks of treatment with vortioxetine in the open-label extension study 
12712A may participate in the present study if they have remitted (CDRS-R total score ≤28) at the last 
2 visits in Study 12712A prior to the rollover. In addition, the dose of vortioxetine must have been fixed for 
the last 4 weeks in Study 12712A prior to randomization in the present study.
Eligible patients will be randomized directly to the 26-week, double-blind treatment period.
The study design is presented in Panel 1 (including the study periods) and the scheduled study procedures and 
assessments are summarized in Panel 2 and Panel 3.
Open-label Period (for de novo patients and rollover patients from Study 12709A)
The duration of the open-label, flexible-dose treatment period will be 12 weeks.
The dosage of vortioxetine will be initiated at 5 mg/day for the first 2 days prior to receiving 10 mg/day.
The target dose is 10 mg/day, however, the investigator has the possibility to increase the dose to a maximum 
of 20 mg/day in case of unsatisfactory response or decrease the dose to 5 mg/day in case of dose-limiting 
adverse events. The dose can be up- or down-titrated with 5 mg/day. The patient should receive the same dose 
for 2 days before being up- or down-titrated to a new dose. Changes in dosing may occur at any visit during 
the first 8 weeks at the investigator's discretion. In addition, between Week 2 and Week 8, the patient and/or 
parent(s)/legal representative(s) can request an unscheduled visit to discuss their current dose. 
From Week 8 onwards the dose has to remain fixed.
Patients in remission (CDRS-R total score ≤28) at both Weeks 10 and 12 or with an adequate clinical 
response (defined as ≥50% reduction in the CDRS-R total score compared to the baseline score in this study 
[subtracted 17 to avoid flooring effect] and a CDRS-R total score ≤35) at both Weeks 10 and 12 will be 
randomized in the double-blind, placebo-controlled, fixed-dose period. 
Patients who do not fulfil the randomization criteria at Week 10 and/or Week 12 will be withdrawn from the 
study and will complete an early Withdrawal Visit. Non-remitters who leave the study will be treated at the 
investigator’s discretion.
A Safety Follow-up Visit will be performed approximately 4 weeks after withdrawal from the open-label 
period.

Double-Blind Period (for all patients)
A total of 80 patients who fulfil the randomization criteria will be randomly assigned via a centralized 
randomization system to receive vortioxetine or placebo in a 1:1 ratio. Randomization will be stratified by 
patient inclusion source (de novo patients, rollover patients from 12709A, or from 12712A).
Patients randomized to vortioxetine will continue on their final dose from the open-label period or the dose 
they had on their last visit in Study 12712A, as applicable. 
The duration of the double-blind, fixed-dose treatment period will be 26 weeks. 
Patients who relapse during the double-blind period must be withdrawn from the study. The criterion for a 
relapse is a CDRS-R total score of ≥40 with a history of 2 weeks of clinical deterioration, or a clinical 
deterioration that in the investigator’s opinion warrants alteration of treatment to prevent full relapse.
A Safety Follow-up Visit will be performed 4 weeks after withdrawal from or completion of the double-blind 
period. 
An independent Data Monitoring Committee (DMC) will monitor safety data at regular intervals as specified 
in the DMC Charter.
This study will be terminated if the result of the currently ongoing placebo-controlled, short-term study 
(12709A) in children is negative (that is, if vortioxetine fails to show a significant difference from placebo in 
acute treatment). In case of study termination, the participating patients will be treated at the discretion of the 
investigator in line with clinical practice.
Number of Patients Planned
Eighty (80) patients are planned for randomization to the 26-week double-blind period (including those who 
rollover from study 12712A): 40 in the vortioxetine group and 40 in the placebo group.
One-hundred fifty (150) patients recruited from specialist settings, mainly outpatient clinics, either as de novo
patients or rollover patients from Study 12709A, are estimated to be enrolled into the study. The exact number 
of enrolled patients will depend on the number and randomization rate of de novo and rollover patients. 
Approximately 40 psychiatric centres are planned for recruitment in approximately 10 countries worldwide.

Statistical Methodology
The following analysis sets will be used to analyse and present the data:
all-patients-enrolled set (APES) – all patients enrolled to the 12-week open-label, flexible-dose treatment 
period who took at least one dose of IMP
all-patients-randomized set (APRS) – all patients randomized to the 26-week double-blind treatment period 
full-analysis set (FAS) – all patients randomized to the 26-week double-blind treatment period who took at 
least one dose of double-blind IMP
The efficacy analyses will be based on the FAS.
Primary analysis: 
Primary efficacy analysis will compare the time to relapse (defined as either a total score ≥40 on the 
CDRS-R with a history of 2 weeks of clinical deterioration, or clinical deterioration as judged by the 
clinician) between Vortioxetine and placebo using a Cox regression model with exact adjustment for ties. A 
one-sided 5% level of significance will be used. Patients not relapsing before Week 26 will be censored at 
Week 26 and patients withdrawing due to other reasons than relapse will be censored at time of withdrawal. 
Sensitivity analysis of the primary endpoint: 
Primary analysis will be repeated ignoring relapses occurring during the first week, two weeks and four 
weeks of the double-blind period, respectively.
The number of relapses will be summarized according to relapse criteria: CDRS-R total score ≥40 with 
2 weeks of clinical deterioration, investigator’s judgement, or both.
Primary analysis will be repeated for the de novo patients and for the (pooled) 12709A patients and 12712A 
patients.
Analyses of secondary endpoints:
Relapse over 26 weeks will be analysed using logistic regression.
Secondary efficacy variables (CDRS-R, PQ-LES-Q, CGI-S, CGI-I) will, on an exploratory basis be 
analysed over the 26-week double-blind period by Mixed Model Repeated Measurements (MMRM) and 
analysis of covariance (ANCOVA) (observed cases [OC] and last observation carried forward [LOCF]).
The population pharmacokinetics (popPK) of vortioxetine in children will be analysed through non-linear 
mixed effect analysis and will be described in a separate popPK analysis plan.
Analyses of other endpoints: 
On an exploratory basis, potential use of psychotherapy in the double-blind period, severity of illness, 
gender, and age will be assessed as covariates or to generate subgroups for the Cox regression model.
Descriptive statistics will be used to compare patient populations and treatment outcome between the 
geographical regions.
The safety analyses will be based on the APES and the FAS.
Analyses of safety endpoints:
AEs, absolute and change from baseline in clinical safety laboratory tests (estradiol for girls, LH, FSH), 
Tanner staging, ECG, and effects on menstrual cycle, vital signs, height, weight, and ECG parameters will 
be summarized, and observed potentially clinically significant (PCS) safety laboratory test values will be 
flagged and summarized. GBI scores (using the 10-item mania subscale), and C-SSRS scores will be 
summarized using descriptive statistics. 
AEs and other safety endpoints will be reported separately for the 12-week open-label period and the 
26-week double-blind period.
Patient disposition and demographics will be summarized using descriptive statistics.

Sample Size Considerations
The calculation of power is based on a log-rank test for the time to relapse at a one-sided 5% level of 
significance using SAS® Proc Power. A sample size of 80 randomized patients (40 patients per treatment group) 
will provide at least 80% power to find a difference between vortioxetine and placebo as statistically 
significant, when expecting cumulative relapse rates at 0.42 and 0.69 over 26 weeks, respectively,
corresponding to a hazard-ratio of 2.15. 
It is anticipated that approximately 60% of de novo patients enrolled into the open-label period will qualify for 
the double-blind study period. One-hundred fifty (150) patients are estimated to be enrolled into the study 
(depending on number and randomization rate of de novo and rollover patients).

Applicable only for 12709A rollover patients. Assessments marked with () in this column will be used 
from 12709A study and therefore not repeated.
d
This visit should take place as soon as possible after the patient withdraws from the study. Any visit during 
the open-label treatment period can be converted into a Withdrawal Visit on the day of the visit.
e
Applicable for patients withdrawn prior or at Visit 8: Safety follow-up should be scheduled approximately 
30 days after the last dose of IMP. It can be a telephone contact, unless an SAE has occurred since the last 
visit or unless there was a clinically significant abnormal safety laboratory test value at the last visit. In 
such cases, safety follow-up(s) must be scheduled to allow for a medical examination and/or blood 
sampling. Further safety follow-up visits beyond 30 days may be needed as judged by the investigator (if 
further safety follow-up visits are performed, these must be recorded in the patient’s medical record, and 
not in the eCRF).

f
If the date of a visit does not conform to the schedule, subsequent visits should be planned to maintain the 
visit schedule relative to the Baseline Visit. Consider that the number of days between 2 visits must not 
exceed the number of days for which the patient has been dispensed IMP.
g
The data from the Screening Visit in the Study 12709A eCRF will be used.
h
The K-SADS-PL will be used to confirm diagnosis of MDD and to assess possible psychiatric co-
morbidities.
i
Values from all assessments and procedures (efficacy/safety, including blood/urine samples and use of 
concomitant medication) performed at the Completion Visit (Visit 12) in Study 12709A will be the 
Baseline Visit values in Study 13546A. 
j
Only for AEs ongoing at Withdrawal and new SAEs.
k
The hormones panel is to be collected at Visit 1 (estradiol in females only).
l
An extra tube of blood samples will be required for hormones at the Study 12709 Week 12 Visit.
m Between Week 2 and Week 8, the patient and/or parents /legal representative can request an unscheduled 
site visit to discuss their current dose. AEs will be collected and C-SSRS, GBI-mania and CGI-S will be 
done at the unscheduled visit.
n
If the patient is a female subject of childbearing potential (defined as females aged ≥10 years old and 
younger girls who, at the discretion of the investigator, are deemed to be of reproductive potential), a urine 
pregnancy test is to be performed at screening and randomization, and at the Withdrawal Visit.
o
It is not mandatory to screen for drugs and/or alcohol. However, it can be performed at any visit, at the 
discretion of the investigator.

a
Patients from Study 12712A who are in remission after 8 to 12 weeks of open-label treatment in study 
12712A will enter directly into the Randomization Visit of this study.
b
This can be a telephone contact, unless an SAE has occurred since the last visit or unless there was a clinically 
significant abnormal safety laboratory test value at the last visit. In such cases, safety follow-up(s) must be 
scheduled to allow for a medical examination and/or blood sampling. Further safety follow-up visits beyond 
30 days may be needed as judged by the investigator (if further safety follow-up visits are performed, these 
must be recorded in the patient’s medical record, and not in the eCRF).
c
If the date of a patient visit does not conform to the study plan, subsequent visits should be planned to 
maintain the visit schedule relative to the Randomization Visit (Visit 8). Consider that the number of days 
between 2 visits must not exceed the number of days for which the patient has been dispensed IMP.
d
For 12712A-patients, last available values from assessments and procedures (efficacy/safety, and use of 
concomitant medication) performed at either Visit 7 (Week 8) and/or Visit 8 (Week 10), or Visit 9 (Week 12) 
in Study 12712A will be the Randomization Visit values for this study, when applicable. For patients who 
rollover at Visit 7 or Visit 8, weight, height, Tanner staging, menstrual cycle, and examinations should be 
done at the Randomization Visits.
e
For 12712A-patients, ongoing AEs and concomitant medication from study 12712A will be used for eCRF.
f
Only for AEs ongoing at Completion/Withdrawal and new SAEs
g
If the patient is a female subject of childbearing potential (defined as females aged ≥10 years old and younger 
girls who, at the discretion of the investigator, were deemed to be of reproductive potential), a urine 
pregnancy test is to be performed at randomization, Visit 13 (double-blind period Week 10) and at 
Completion/Withdrawal Visit. Additional pregnancy tests during the study will be performed according to 
local requirements. 
h
It is not mandatory to screen for drugs and/or alcohol. However, it can be performed at any visit, at the 
discretion of the investigator. 
i
Only for 12712A-patients who rollover into double-blind phase.

Introduction
1.1
Background
1.1.1
Overview
Mood disorders in children and adolescents are among the most debilitating illnesses, exerting 
a major impact on family and social functioning, school performance and an increased risk of 
recurrence, substance abuse, psychiatric comorbidity and suicidality.1,2,3,4
The prevalence of Major depressive disorder (MDD) is estimated to be approximately 2% in 
children and 4 to 8% in adolescents.3,4,5,6
Signs and symptoms of MDD are similar to the adult population, but depressive disorders 
meeting the diagnostic criteria are rarely present before the age of seven years.7,8 The clinical 
picture may differ according to age at presentation. Children may have mood liability, 
irritability, low frustration tolerance, somatic complaints, and/or social withdrawal instead of 
verbalising feelings of depression, whilst adolescents are more likely to complain of feelings 
of hopelessness/helplessness, lack of energy and to have a higher rate of suicidal thoughts.9,10
Although several acute treatment studies of antidepressants have been completed in the MDD 
patient population, only two antidepressants have shown replicate efficacy in two or more 
trials and have received regulatory approval for the treatment of MDD in paediatric patients. 
Fluoxetine is currently approved in both Europe and the US for the treatment of children and 
adolescents with MDD 11,12 and escitalopram is approved in the US for the treatment of 
adolescents with MDD.13,14 Thus, there is a critical need to broaden current pharmacological 
treatment options for this patient population.
The aim of this study is to evaluate the efficacy of vortioxetine versus placebo in preventing
relapse of depressive symptoms in children aged 7 to 11 years with a DSM-5TM diagnosis of 
MDD.
The following sections provide an overview of the nonclinical and clinical data currently 
available for vortioxetine. For further information, please refer to the current version of the 
Investigator’s Brochure (IB).15
1.1.2
Nonclinical Data
The mechanism of action of vortioxetine is thought to be related to its direct modulation of 
serotonergic receptor activity and inhibition of the serotonin (5-HT) transporter (SERT). 
Nonclinical data indicate that vortioxetine is a 5-HT3, 5-HT7, and 5-HT1D receptor 
antagonist, 5-HT1B receptor partial agonist, 5-HT1A receptor agonist and inhibitor of the 
SERT, leading to modulation of neurotransmission in several systems. This multimodal 
activity is considered to be responsible for the antidepressant and anxiolytic-like effects and

the improvement of cognitive function, learning and memory observed with vortioxetine in 
animal studies.16
Average exposures to vortioxetine and metabolites at the relevant human therapeutic doses are 
below the toxicity levels (NOAEL) determined in animals. In support of the paediatric 
program, 3 juvenile toxicity studies were completed. These studies concluded that no new or 
critical vortioxetine treatment-related findings were seen in juvenile rats compared to the 
repeat-dose toxicity and reproductive studies in adult rats.
1.1.3
Clinical Data
This relapse-prevention study is part of agreed European Medicines Agency (EMA) Paediatric 
Investigational Plan (PIP) to evaluate vortioxetine in the treatment of MDD in children and 
adolescents. The PIP includes a total of 6 studies:
Study 12708A that investigated pharmacokinetics (PK) and safety in children and 
adolescents 
2 short-term efficacy studies: Study 12709A in children and Study 12710A in adolescents 
2 open-label extension studies to Studies 12709A and 12710A: 12712A (6 months) and 
12712B (extension to 12712A; 18 months) 
Relapse-prevention study 13546A
The PK study, 2 short-term studies, and the 6- month extension study are also part of the 
paediatric programme for vortioxetine agreed with the US Food and Drug Administration 
(FDA). Of the 2 short-term efficacy and safety studies, Study 12710A in adolescents has been 
completed with a negative outcome, whereas Study 12709A in children is still ongoing. Of the 
2 open-label extension studies of 6 and 18 months’ duration that enrol completers from the 
short-term studies, Study 12712A (6-month extension) is ongoing and enrolling patients from 
12709A. Study 12712B which enrolled completers from Study 12712A has been completed. 
The data available from these studies are described in the following sections.
1.1.3.1
Pharmacokinetics
In adults, vortioxetine has shown to be a compound with slow absorption, large volume of 
distribution and medium clearance. Vortioxetine is slowly, but well absorbed after oral 
administration and the peak plasma concentration is reached within 7 to 11 hours. Following 
multiple dosing of 5, 10, or 20 mg/day, mean maximum observed concentration (Cmax) values 
of 9 to 33 ng/mL were observed. The absolute bioavailability is 75%. No effect of food on the 
pharmacokinetics was observed. The mean volume of distribution (Vss) is 2,600 L, indicating 
extensive extravascular distribution. Vortioxetine is highly bound to plasma proteins (98 to 
99%) and the binding appears to be independent of vortioxetine plasma concentrations. 
Vortioxetine is extensively metabolised in the liver, primarily through oxidation catalysed by 
CYP2D6 and to a minor extent CYP3A4/5 and CYP2C9, and subsequent glucuronic acid 
conjugation. No inhibitory or inducing effect of vortioxetine was observed in the drug-drug 
interaction studies for the CYP isozymes CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, 
CYP2C19, CYP2D6, CYP2E1, or CYP3A4/5. Vortioxetine is a poor P-gp substrate and

inhibitor. The major metabolite (Lu AA34443) of vortioxetine is pharmacologically inactive. 
The mean elimination half-life and oral clearance are 66 hours and 33 L/h, respectively. The 
pharmacokinetics is linear and time independent in the dose range studied (2.5 to 
60 mg/day).15
In the paediatric PK study (12708A), the pharmacokinetic properties of vortioxetine in the 
children and adolescent population after 14 days of dosing with 5, 10, 15 and 20 mg were 
investigated. Data showed that the exposures to vortioxetine and its metabolite Lu AA34443, 
in terms of Cmax and area under the curve (AUC), increased in a dose-proportional manner and 
were generally lower in the adolescent patients than in the children, but data suggests that the 
doses tested (5 to 20 mg/day vortioxetine) and the uptitration scheme employed in this study 
are appropriate for the paediatric population.
In the short-term efficacy study for adolescents (12710A), vortioxetine steady-state exposures 
in adolescents were similar to those previously reported in adults both for vortioxetine 10 mg 
and 20 mg. Regarding PK/PD, no apparent relationships could be found between the efficacy 
variables and plasma exposure of vortioxetine at the end of the double-blind period, which was 
in line with the primary analysis showing negative results for vortioxetine. Based on PK data, 
16% of the vortioxetine-treated patients (11% in the 10 mg group and 20% in the 20 mg 
group) and 14% of the vortioxetine and fluoxetine treated patients, could be regarded as 
non-compliant in this study.
1.1.3.2
Efficacy
Adults
Vortioxetine has been approved in the United States (US), European Union (EU) and a 
number of other countries for the treatment of MDD in the adult population. Broad efficacy on 
depressive symptoms has been proven in an extensive clinical development program. 
Vortioxetine was efficacious, safe, and well tolerated in adults and in the elderly with MDD in 
short-term treatment and long-term maintenance. This also includes proven effect of 
vortioxetine on cognitive dysfunction in adult patients with MDD, assessed using a range of 
objective neuropsychological tests.
Paediatrics
An 8-week, randomized, double-blind, placebo-controlled, active-reference, fixed-dose, study 
(Study 12710A) was conducted in adolescent patients with MDD aged 12 to 17 years. The 
study included a 4-week, single-blind, placebo lead-in period with standardized psychosocial 
intervention (N=777); only non-responders from the lead-in period were randomized (N=616). 
The study was concluded negative: similar improvements in depressive symptoms were 
observed over 8 weeks for vortioxetine and placebo-treated patients, with no statistically 
significant differences between vortioxetine and placebo on the primary endpoint (mean 
change from baseline to end-point [8 weeks] on the CDRS-R total score). The active reference 
(fluoxetine 20 mg/day) separated from placebo on the CDRS-R total score, however, a 
substantial placebo response was still observed.

In a similarly designed study in children with MDD aged 7 to 11 years (Study 12709A), an 
interim analysis was conducted based on data from 271 randomized patients to potentially 
terminate the study, if there was sufficient evidence of an effect of vortioxetine, or a clear lack 
thereof. As the results of the interim analysis met neither the efficacy nor the futility criterion, 
and no safety concerns have been raised, the study should continue as planned until the 
prespecified sample size of 539 patients has been reached. A review of unblinded efficacy data 
from the interim analysis by an independent data monitoring committee (DMC) indicated no 
concerns that would preclude continuation of studies of vortioxetine in children.
The efficacy data from the open-label extension studies (ongoing Study 12A and completed 
Study 12B) indicate continuous improvements on depressive symptoms in patients who 
continued to receive vortioxetine for up to 6 months or 24 months, respectively. 
1.1.3.3
Safety
Adults
The evaluation of the safety and tolerability of vortioxetine is based on data from a large 
clinical development programme and extensive post-approval experience (see IB15). Overall 
short- and long-term treatment with vortioxetine at the therapeutic doses (5 to 20 mg/day) was 
safe and well tolerated in adults and in the elderly. The incidence of nausea, the most common 
adverse event (AE), showed a trend towards a dose-response relationship. For vortioxetine, at 
the therapeutic doses, the incidences of AEs such as insomnia, somnolence, fatigue, and 
hyperhidrosis, were at placebo level, as was the incidence of sexual dysfunction. The changes 
in body weight, vital signs, electrocardiograms (ECGs) (including the QTc interval), and 
clinical safety laboratory tests (including liver and renal tests) were at placebo level for all 
therapeutic doses of vortioxetine. 
Paediatrics
The dose range of vortioxetine (5 to 20 mg/day) was chosen based on the knowledge from the 
clinical development programme in adult patients and the results of a paediatric 
pharmacokinetic and tolerability study (Study 12708A), which indicated that no dose 
adjustment was needed in the paediatric population. Hence, the doses known to be efficacious 
in the adult population (5 to 20 mg/day) and used in the paediatric development programme
are confirmed as well tolerated based on the current large paediatric database.
Study 12708A, 24 children and 24 adolescents (aged 7 to 17 years) with a depressive or 
anxiety disorder were treated with vortioxetine 5 to 20 mg/day. Based on the data from this 
study, no concerns were raised on the safety and tolerability profile of vortioxetine. 
Vortioxetine was safe and well tolerated following 14 days of dosing, as well as during an 
initial up-titration period and following 6 months of treatment. Overall, the tolerability profile 
in adolescents and children in this study was similar to that in adults with no new types of 
AEs.
Study 12710A, 308 adolescents (aged 12 to 17 years) with MDD were treated with 
vortioxetine 10 or 20 mg/day. In general, the adverse reaction profile of vortioxetine in

adolescents was similar to that in adults. The AEs with an incidence ≥5% in the vortioxetine 
groups were nausea, headache, vomiting, nasopharyngitis, diarrhoea, and dizziness. In 
particular, the incidences were higher in the vortioxetine groups than in the placebo group for 
nausea, headache, and vomiting. The mean changes from randomization in the clinical safety 
laboratory tests; vital signs; weight, body mass index (BMI), and height; and ECG parameters 
were small, comparable between treatment groups, and not clinically relevant.
Study 12712B, an open-label, flexible-dose, 18-month extension study to Study 12712A, (a 
6-month, open-label extension study), 94 children and adolescents (aged 7 to 17 years) with 
MDD were treated with vortioxetine 5 to 20 mg/day. None of the patients had a serious AE or 
an AE leading to withdrawal. Overall, the AE profile was similar in children and adolescents. 
The AEs with an incidence ≥5% were headache, nausea, nasopharyngitis, abdominal pain 
upper, hyperprolactinaemia, respiratory tract infection viral and vomiting. All the patients with 
hyperprolactinaemia were asymptomatic. Except for prolactin, the mean changes from 
baseline in all the other safety laboratory tests, vital signs, and ECG parameters were small 
and not clinically relevant.
Based on the completed paediatric studies, no new important risks have been identified in the 
paediatric population beyond those established for the adult population. In the paediatric 
patients, the safety and tolerability profile of vortioxetine after long-term use was comparable 
to that observed after short-term use. This conclusion is also supported by data emerging from 
the ongoing 6-month extension study 12712A that to date enrolled nearly 600 patients. For the 
ongoing, blinded study in children, continuous review of unblinded safety data by the DMC 
did not raise any safety concerns. Overall, there are no findings that would preclude 
continuation of studies of vortioxetine in children.
1.2
Rationale for the Study
This study is part of the agreed EMA PIP for vortioxetine with the purpose to investigate the 
antidepressant effect of vortioxetine in paediatric patients with MDD. The study is designed to 
evaluate maintenance of antidepressant effect in children aged 7 to 11 years who continue to 
receive vortioxetine compared with children switched to placebo after response to vortioxetine 
treatment.

COVID 19 Related Risk Assessment and Mitigation
Appropriate risk assessment has been performed and mitigations to be done in case of 
restrictions due to COVID-19 are described in detail in a separate “COVID-19 Mitigation

Study Design
3.1
Overview of the Study Design
This study has been designed in accordance with the Declaration of Helsinki17 and will be 
conducted in compliance with the protocol, Good Clinical Practice,18 and applicable 
regulatory requirements.
This is an interventional, multi-national, multi-site, randomized, parallel-group, placebo-
controlled, relapse-prevention study in paediatric patients with MDD from 7 to 11 years of 
age. 
The study consists of a 12-week, open-label, flexible-dose treatment period with vortioxetine 
followed by a 26-week, randomized, double-blind, fixed-dose, placebo-controlled 
relapse-prevention period.
The study population will include de novo patients as well as rollover patients from other 
paediatric vortioxetine studies (Studies 12709A and 12712A), who, in the investigator’s 
opinion, could benefit from continued treatment with vortioxetine. To reach 80 randomized 
patients, approximately 150 patients recruited, either as de novo patients or rollover patients 
from Study 12709A, are estimated to be enrolled into the study.
De novo patients 
Patients meeting eligibility criteria for de novo patients will be enrolled in the 12-week,
open-label, flexible-dose treatment period.
Rollover patients from Study 12709A (enrolled to the open-label period)
Patients may participate in the present study after completion of the randomized, 8-week,
double-blind, placebo-controlled treatment period of Study 12709A. 
Eligible patients will be enrolled in the 12-week, open-label, flexible-dose treatment period.
The Baseline Visit of this study (Study 13546A) will take place at the same visit as Visit 12 
(Completion Visit) of Study 12709A. Participation in Study 12709A is considered 
completed when all assessments required at Visit 12 are completed.
Rollover patients (remitters) from Study 12712A (randomized to the double-blind period)
Patients who have received 8 to 12 weeks of treatment with vortioxetine in the open-label 
extension study 12712A may participate in the present study if they have remitted 
(CDRS-R total score ≤28) at the last 2 visits in Study 12712A prior to the rollover. In 
addition, the dose of vortioxetine must have been fixed for the last 4 weeks in 
Study 12712A prior to randomization in the present study.
Eligible patients will be randomized directly to the 26-week, double-blind treatment period.
An overview of the study is presented in Panel 1 (including the study periods) and the 
scheduled study procedures and assessments are summarized in Panel 2 and Panel 3.

Open-label Period (for de novo patients and rollover patients from Study 12709A)
The duration of the open-label, flexible-dose treatment period will be 12 weeks.
The dosage of vortioxetine will be initiated at 5 mg/day for the first 2 days prior to 
receiving 10 mg/day.
The target dose is 10 mg/day, however, the investigator has the possibility to increase the 
dose to a maximum of 20 mg/day in case of unsatisfactory response or decrease the dose to 
5 mg/day in case of dose-limiting AEs. The dose can be up- or down-titrated with 
5 mg/day. The patient should receive the same dose for 2 days before being up- or down-
titrated to a new dose. Changes in dosing may occur at any visit during the first 8 weeks at 
the investigator's discretion. In addition, between Week 2 and Week 8, the patient and/or 
parent(s)/legal representative(s) can request an unscheduled visit to discuss their current 
dose. The maximum dose may not exceed 20 mg/day. The minimum dose is 5 mg/day.
From Week 8 and onwards the dose has to remain fixed.
Patients in remission (CDRS-R total score ≤28) at both Weeks 10 and 12 or with an 
adequate clinical response (defined as ≥50% reduction in the CDRS-R total score compared 
to the baseline score in this study [subtracted 17 to avoid flooring effect] and a CDRS-R 
total score ≤35) at both Weeks 10 and 12 will be randomized in the double-blind, placebo-
controlled, fixed-dose period. 
Patients who do not fulfil randomization criteria for remission or adequate response at 
Week 10 and/or Week 12 will be withdrawn from the study and will complete an early 
Withdrawal Visit. Non-remitters/non-responders who leave the study will be treated at the 
investigator’s discretion.
A Safety Follow-up Visit will be performed approximately 4 weeks after withdrawal from 
the open-label period.
Double-blind Period (for all patients)
Patients who fulfil the randomization criteria and do not meet any of the withdrawal criteria 
will be randomly assigned via a centralized randomization system to receive vortioxetine or 
placebo in a 1:1 ratio. Randomization will be stratified by patient inclusion sources (de 
novo patients, rollover patients from 12709A, or from 12712A).
Patients randomized to vortioxetine will continue on their final dose from the open-label 
period or the dose they had on their last visit in Study 12712A, as applicable. 
The duration of the double-blind period will be 26 weeks. 
Patients who relapse during the double-blind period must be withdrawn from the study. The 
criterion for a relapse is a CDRS-R total score of ≥40 with a history of 2 weeks of clinical 
deterioration, or a clinical deterioration that in the investigator’s opinion warrants alteration 
of treatment to prevent full relapse. 
A Safety Follow-up Visit will be performed 4 weeks after withdrawal or completion of the 
double-blind period.

Rationale for the Study Design
This relapse-prevention study is part of the agreed EMA PIP to evaluate the PK, efficacy and 
safety of vortioxetine in the treatment of MDD in children and adolescents (section 1.1.3).

Study 13546A – Clinical Study Protocol
Page 33 of 85
Due to the character of the disorder, long-term studies are necessary to demonstrate that the 
short-term effect is maintained during an episode. This study will evaluate the antidepressant 
effect of vortioxetine in decreasing the rate of relapse using a randomised withdrawal design, 
which is the design of choice to establish maintenance of effect of long-term treatment within 
the episode.19 In this design, responders to an open-label course of the studied antidepressant 
are randomized to continue on the study drug or be switched to placebo and are observed for 
relapse over a defined period of time.
This study will enrol children 7 to 11 years of age. Adolescents will not be included in this 
study due to the negative results of the short-term efficacy and safety study in adolescents 
(Study 12710A).
Recruitment of young children with MDD into clinical studies is challenging for multiple 
reasons, including low prevalence of depression in this age group, difficulties in diagnosing 
MDD, reluctance to participate in a placebo-controlled study, and the burden on families 
associated with participation in a research study. To minimize the challenges associated with 
recruitment of de novo patients and to optimize the study design and feasibility, without 
compromising the validity or integrity of the study, children who complete 8 weeks of double-
blind treatment in the short-term study (12709A) and who could benefit from continued 
treatment with vortioxetine will be invited to participate in this study. The same approach was 
applied in a previous fluoxetine relapse-prevention study.20 In addition, patients who have 
received vortioxetine for 8 to 12 weeks in the open-label extension study (Study 12712A; 
6 months extension) and achieved stable remission may be enrolled. These patients will be 
randomized directly to the double-blind randomized treatment phase, as they have already 
stabilized on vortioxetine treatment. Inclusion of rollover patients who may have received 
vortioxetine for more than 12 weeks is supported by the results of an FDA review of 
relapse-prevention studies in adults which found no relationship between the length of the 
open-label phase and relapse rates in the placebo or drug arms.21
The duration of the double-blind treatment phase of 26 weeks is considered sufficient based on 
the experience from previous relapse-prevention studies in children22.
While acute studies in MDD tend to suffer from lack of sensitivity, placebo response appears 
to be of lesser concern in studies using this randomized withdrawal design which enrol only 
patients who tolerate and respond to a studied drug in the acute phase into the maintenance 
phase. Because it is “enriched” with responders/remitters, the differences between the two 
groups are typically larger than in the acute, parallel design studies. Virtually all 
antidepressants, irrespective of the class, that demonstrated efficacy in short-term studies have 
also demonstrated efficacy in relapse-prevention studies.
The dose range of vortioxetine (5 to 20 mg/day) was chosen based on the knowledge from the 
clinical development programme in adult patients and the results of a paediatric 
pharmacokinetic and tolerability study (Study 12708A), which indicated that no dose 
adjustment was needed in the paediatric population. Hence, the doses known to be efficacious 
in the adult population (5 to 20 mg/day) are used in the paediatric development programme 
and are confirmed as well tolerated based on the current large paediatric database.

Ethics
4.1
Ethical Rationale
Patients and their parent(s)/legal representative(s) will be fully informed about the study 
including the risks and benefits of his or her participation. The patient may withdraw from the 
study at any time, for any reason. Unscheduled visits can be made and immediate withdrawal 
is possible. Throughout the study, signs of suicidal risk will be assessed and patients at risk 
will be withdrawn.
The risks associated with the study are considered well controlled by cautionary measures in 
the study design, and well balanced with the potential benefits of the treatment. 
Vortioxetine is approved in 88 countries worldwide, including the US and EU, for the 
treatment of MDD in the adult population. As summarized in section 1.1.3, in the 3 completed 
paediatric studies, vortioxetine was safe and well-tolerated in paediatric patients with MDD
aged 7-17 years and the safety and tolerability profile of vortioxetine after long-term use was 
comparable to that observed after short-term use. Overall, based on the data from 3 completed 
paediatric studies and data available to date from the ongoing studies in children aged 
7-11 years, no new important risks have been identified in the paediatric population beyond 
those established for the adult population.
Vortioxetine did not separate from placebo in the short-term study in adolescents (12710A),
however, the results of the interim analysis in a similarly designed study in children found no 
evidence of futility. Furthermore, a review by an independent data monitoring committee
(DMC) of unblinded efficacy as well as continuous review of safety data from the children 
study (12709A) and the OLE 12712A data indicate no concerns that would preclude 
continuation of studies of vortioxetine in children.
The present study will permit the investigation of the efficacy - in particular maintenance of 
antidepressant effect - of a new potential treatment of MDD in children. The inclusion of a 
placebo group has major scientific importance in this evaluation to ensure adequate evaluation 
of efficacy. 
As stated in section 3.2 above, to address the challenges associated with recruitment of 
de novo patients and to minimize the number of patients exposed to IMP, the study will also
enrol rollover patients from Studies 12709A and 12712A.
The definition of relapse (CDRS-R score of ≥40 with a history of 2 weeks of clinical 
deterioration, or clinical deterioration as judged by the clinician) has been carefully considered 
and aligned with the previous study of fluoxetine 23, to avoid participants becoming too ill 
before declaring a relapse, but also to avoid counting minor worsening (which might improve 
spontaneously) as a sign of relapse. The patients will be asked to attend the investigational 
clinic at regular intervals to ensure an adequate follow-up. The visits will be performed either 
as a visit in an outpatient clinic or as a phone call. In order to minimize potential pain, distress, 
and fear, patients will be seen in facilities which will be appropriate for children; the study

personnel who interact with the patients will be experienced health care professionals 
(physicians with paediatric qualification, qualified paediatric nurses or psychologists); their 
education, training and experience will be documented. Age-appropriate explanations will be 
given to the child prior to any investigation or procedure, in order to decrease anxiety and 
anticipation of pain. Potentially painful procedures such as venepuncture will be minimized 
with the use of for example topical anaesthesia before venepuncture. Blood sampling will be 
limited to the minimum required for obtaining valid data for evaluation. The number of blood 
samples and visits has been carefully evaluated against the value for the overall objectives of 
the study.
Because the duration of the study (9 months) precludes withholding appropriate treatment for 
attention-deficit/hyperactivity disorder (ADHD), participants are allowed to be on stimulant 
treatment during the study if they have been on a stable dose for at least 4 weeks prior to study 
entry. The addition of stimulant treatment is not allowed during the study.
The selection criteria exclude the participation of patients at significant risk of suicide, and 
patients becoming at significant suicidal risk during the study will be withdrawn. Throughout 
the study, potential suicidal risk will be assessed by using the Columbia-Suicide Severity 
Rating Scale and by the investigator’s judgement. The GBI 10-item mania is included to 
screen for manic symptoms in children.
In accordance with Good Clinical Practice18, qualified medical personnel at Lundbeck and the 
contract research organisation (CRO) will be readily available to advise on study-related 
medical questions. Medical monitoring and safety surveillance will be performed throughout 
the study, according to Lundbeck standard procedures and Lundbeck will regularly monitor 
and re-examine the balance of risks and benefits of the full clinical study so that the health and 
wellbeing of the paediatric patients enrolled will be safeguarded.
The independent DMC for the paediatric vortioxetine programme will be continued 
throughout this study in order to review the safety and tolerability data (section 10.6). 
In accordance with Good Clinical Practice,18 the investigator will be responsible for all 
study˗related medical decisions.
4.2
Informed Consent
No study-related procedures, including any screening procedures, may be performed before 
the investigator has obtained written assent from the patient and written informed consent 
from his or her parent(s)/legal representative(s).
Changing (for example, discontinuing or down-tapering) a patient’s concomitant medications 
prior to the Screening Visit to ensure that the patient meets the selection criteria is a 
study-related activity and must not occur before the Informed Assent/Consent Forms have 
been signed.

Minors are dependent on their parent(s)/legal representative(s) (typically their parent[s]) to 
assume responsibility for their participation in clinical studies.24
If the informed assent/consent process may be delegated, the requirements for the delegates 
must be documented prior to the start of the study. National laws must always be adhered to 
when allowing potential delegation. Any delegation must be documented in the site delegation 
log.
The investigator must identify vulnerable patients, that is, patients whose willingness to 
participate in this study might be unduly influenced by the expectation, regardless of whether 
it is justified, of benefits associated with participation, or of a retaliatory response from senior 
members of a hierarchy in case of refusal to participate. Patients thus identified must be 
excluded from participation in the study.
Prior to obtaining written informed assent/consent, the investigator or a designee must explain 
to the patients and their parent(s)/legal representative(s) the aims and methods of the study and 
any reasonably expected benefits and foreseeable risks or inconveniences to the patients.
The patients and their parent(s)/legal representative(s) must be informed:

that their participation in the study is voluntary and that they are free to withdraw from the 
study at any time without justifying their decision

of the possibility of withdrawing consent (section 8.5)

of their right to request a copy of their personal data from the study via the investigator

of their right to be informed by the investigator, after the study has been reported, about 
which treatment they received

of their right to receive information about the study results from the investigator on the 
patient’s own initiative; the results will be available approximately 1 year after the end of 
the study
The patients and their parent(s)/legal representative(s) must be informed that persons 
authorized by Lundbeck and authorized personnel from certain authorities (domestic, foreign, 
data protection agencies, or independent ethics committees (IECs)/institutional review boards 
(IRBs) may view their medical records. The patients and their parent(s)/legal representative(s) 
must also be informed that de-personalized copies of parts of their medical records may be 
requested by authorized personnel from certain authorities (domestic, foreign, data protection 
agencies, or IECs/IRBs) for verification of study procedures and/or data. The confidentiality 
of the patients will in all cases be respected.
The patients and their parent(s)/legal representative(s) must be given ample time and 
opportunity to enquire about details of the study prior to deciding whether to participate in the 
study.
It is the responsibility of the investigator to ensure that all questions about the study are 
answered to the satisfaction of the patients and their parent(s)/legal representative(s). Prior to 
allowing a patient to participate in the study, an Informed Assent/Consent Form must be 
signed and dated (including the time) by the patient and the patient’s parent(s)/legal

representative(s) and/or (co-)signed by an impartial witness (if applicable) and signed and 
dated by the investigator or a designee on the same day. If the patient and/or the patient’s 
parent(s)/legal representative(s) (if applicable) is/are able to understand the nature and 
potential consequences of the interventions and is/are able to give consent, but not in writing, 
an impartial witness, in addition to the informing physician, must sign the Informed Consent 
Form. The patients and their parent(s)/legal representative(s) (if applicable) must be given a 
copy of the written information (Patient Information Sheet) as well as a copy of the signed 
Informed Assent/Consent Form.
The consent procedures described above will only be implemented if allowed by local laws
and regulations and will only be initiated after approval by the relevant IECs/IRBs.
4.3
Personal Data Protection
The data collected in this study will be processed in accordance with the specifications 
outlined in the Danish Data Protection Act and the European Union legislation25 to ensure that 
requirements regarding personal data protection are met. If an external organization will 
process data on behalf of Lundbeck, a contractual procedure will be signed between Lundbeck 
and the external organization to ensure compliance with the above-mentioned legislation.
4.4
Ethics Committee(s) and Institutional Review Board(s) 
This study will be conducted only after Lundbeck has received confirmation that the 
regulatory authorities have approved or confirmed notification of the study and that written 
approval of the protocol has been granted by the appropriate IEC or IRB.
The investigator must not allow any patients to participate in the study before receiving 
confirmation from Lundbeck or the CRO that the required approvals and/or notifications have 
been received.
The IEC or IRB must be informed when specific types of protocol amendments have been 
made and written approval must be obtained before implementation of each amendment, if 
required by local law.
If applicable, interim reports on the study and reviews of its progress will be submitted to the 
IEC or IRB by the investigator at intervals stipulated in its guidelines.
4.5
Regulatory Approval/Notification Requirements
In accordance with local requirements, this study will be submitted to the regulatory 
authorities for approval or notification. The study will only be undertaken when Lundbeck has 
received written approval or confirmation of notification from the regulatory authorities.

6.1
Treatment Regimen
Open-label period:
The dosage of vortioxetine will be initiated at 5 mg/day for the first 2 days prior to receiving 
10 mg/day. The vortioxetine target dose is 10 mg/day, however the investigator has the 
possibility to increase the dose to a maximum of 20 mg/day in case of unsatisfactory response 
or decrease the dose to 5 mg/day in case of dose-limiting AEs. The dose can be up- or 
down-titrated with 5 mg/day. The patient should receive the same dose for 2 days before being 
up- or down-titrated to a new dose. Changes in dosing may occur at any visit during the first 8 
weeks at the investigator's discretion. From Week 8 onwards the dose has to remain fixed.
The tablets should be taken once daily, preferably at the same time each day. 
Double-blind period: 
Patients who fulfil the randomization criteria will be randomly assigned via a centralized 
randomization system to receive vortioxetine or placebo in a 1:1 ratio. Randomization will be 
stratified by patient inclusion sources (de novo patients, rollover patients from 12709A, or 
from 12712A).
Patients randomized to vortioxetine will continue on their final dose from the open-label 
period or the dose they had on their last visit in Study 12712A, as applicable.
The capsules should be taken once daily, preferably at the same time each day.

6.3
Manufacturing, Packaging, Labelling, and Storage of IMPs
The IMPs will be manufactured, packaged, labelled, released (by a qualified person [QP]), and 
distributed in accordance with the principles of Good Manufacturing Practice, under the 
responsibility of Lundbeck.
For the open-label period, the IMP will be provided in 1-week wallet cards, containing 
10 tablets of vortioxetine 5 mg, 10 mg, 15 mg or 20 mg, respectively. At the baseline visit 
(Visit 2), an up-titration wallet card containing 2 × 5 mg vortioxetine tablets and 8 × 10 mg 
vortioxetine tablets will be provided.
For the double-blind period, the IMP will be provided in 1-week wallet cards, containing 
10 capsules vortioxetine (5 mg, 10 mg, 15 mg or 20 mg) or placebo.
The wording on the labels will be in accordance with Good Manufacturing Practice regarding 
labelling and national and/or local regulatory requirements. If additional information is to be 
added when the IMP is dispensed to the patients, this will be clearly stated on the labels, and 
the investigator will be instructed to do so.
No manipulation, repackaging, or relabelling of IMP is permitted after QP release by 
Lundbeck, unless a repackaging/relabelling agreement exists, and the documentation is 
available to Clinical Supply, H. Lundbeck A/S, and, where necessary, new QP releases are 
made.
The IMPs will be identified using a unique medication number.
The IMPs must be stored in a safe and secure location, and in accordance with the storage 
conditions specified on the labels.
6.4
Method of Assigning Patients to Treatment
Interactive response technology (IRT) will be used in this study. The patient’s screening 
number from the lead-in studies will be used to identify the rollover patients in this study. De 
novo patients will be assigned a screening number by the IRT, and that number will be used to 
identify de novo patients throughout the study. When a patient is to be randomized, the 
investigator uses the IRT. The IRT allocates the patient to a treatment group during the call 
and assigns the patient a randomization number in accordance with the specifications from

6.5
IMP Accountability
IMP accountability is documented in the IRT.
The investigator and the pharmacist (if applicable) must agree to only dispense IMP to patients 
enrolled in the study. The investigator or the pharmacist (if applicable) must maintain an 
adequate record of the receipt and distribution of the IMPs. This record must be available for 
inspection at any time.
6.6
Unblinding Procedures
Pharmacovigilance, H. Lundbeck A/S, and the investigator or the pharmacist (if applicable), 
and the DMC will have access to the unblinded information for the double-blind treatment for 
each patient. Access to these details will be via IRT.
The IRT unblinding procedure is described in the IRT User Guide.
The investigator may only break the code for a patient if knowledge of the IMP is necessary to 
provide optimal treatment to the patient in an emergency. If possible, the investigator must 
consult the medical monitor before breaking the code. The investigator must record the date 
and reason for breaking the code on the IMP Code Break Form. If the emergency was an AE, 
it must be recorded on an Adverse Event Form. The medical monitor must be notified 
immediately. The IRT will capture the date and time of the code break call. Information on the 
allocated treatment will be provided during the call and by fax or email, depending on 
availability/preference. When the code is broken for a patient, the patient must be immediately 
withdrawn from the study. If this occurs during a visit, the investigator must complete the visit 
as a Withdrawal Visit; otherwise, the patient will be asked to attend a Withdrawal Visit.
6.7
Post-study Access to IMP
Post-study access to the IMPs will not be available. Patients in the study will have access to 
appropriate medical care after they complete or withdraw from the study.
7
Concomitant Medication
Concomitant medication is any medication other than the IMPs that are taken during the study, 
including the Screening Period up to Safety Follow-up.
The concomitant medications that are disallowed or allowed with restrictions during the study 
are summarized in Appendix II.
Details of all concomitant medication (prescription and over-the-counter) taken <3 months 
prior to the Screening Visit must be recorded in the electronic case report form (eCRF) at the 
first visit. Any changes (including reason for changes) in concomitant medication must be 
recorded at each subsequent visit. For any concomitant medication initiated or for which the

worsening must be recorded as an adverse event.
Concomitant medication initiated after the last dose of IMP must only be recorded if 
associated with a SAE.

Study Visit Plan
8.1
Overview
An overview of the procedures and assessments to be conducted during the study and their 
timing is presented in Panel 2 and Panel 3. Further details are in chapter 9.
After completing or withdrawing from the study, the patient must be treated in accordance 
with usual clinical practice.
8.2
Screening Visit (Visit 1)
The Screening visit will be performed only for de novo patients. Patients rolling over from 
Study 12709A will proceed directly to the Baseline Visit.
The screening period begins when the first screening assessment is done, after written 
Informed Assent/Consent has been obtained. If there is a need for washout of disallowed 
medication, it should be completed before any Baseline (Visit 2) assessment is done and must 
comply with the required washout periods in Appendix II.
The Baseline visit should be scheduled 5 to 15 days after the Screening Visit. However, in 
exceptional cases, the visit interval between the Screening and Baseline Visits may be 
extended up to 30 days with consent from the Medical Monitor, provided the Medical Monitor 
accepts the rationale provided for the extension.
8.2.1
Pre-screening
Each site must record in a pre-screening log which patients attended the Screening Visit.
Preferably within 24 hours from the Screening Visit, a study-specific Pre-Enrolment Form 
needs to be completed for de novo patients by the site and transmitted to the CRO for their 
review. A confirmation that de novo patients can continue further with the study procedures is 
required before enrolment.
8.2.2
Patient Identification Card
Each patient will be provided with a patient identification card that states, at a minimum, the 
name of the IMP, the study number, the patient identification number, the investigator’s name, 
and an emergency telephone number providing 24-hour service.

Page 48 of 85
The patient identification card should be returned to the investigator upon completion of the 
patient’s participation in the study.
8.2.3
Re-screening
Re-screening is only allowed for de novo patients with a complete Screening Visit and who 
fail to attend the Baseline Visit within the planned window due to e.g., logistical constraints.
Only the sponsor’s medical expert (or the CRO’s medical monitor) may give permission to 
re-screen a patient.
Authorization for re-screening may only be granted by the CRO’s medical monitor after a 
thorough review of all data from the original Screening Visit.
At the new Screening Visit, the patient (and/or his or her parent(s)/legal representative(s) [if 
applicable] and/or the responsible caregiver) must sign new Informed Assent/Consent Forms
At the new Screening Visit, the patient will be assigned a new screening number. A re-
screened patient must have a complete new Screening Visit, and all the eligibility criteria must 
be re-assessed at the new Screening Visit.
The following information will also be recorded in the eCRF at the new Screening Visit:

that the patient has previously been screened for the study

that re-screening has been authorized by the CRO’s medical monitor

the screening number that was assigned to the patient at the original Screening Visit
If a patient is re-screened, no data from the original Screening Visit will be used.
A patient may only be re-screened once.
8.3
Baseline Visit Open-label Period (Visit 2)
De novo patients who continue to meet all inclusion criteria and none of the exclusion criteria 
(see section 5.3) will be enrolled into a 12-week open-label treatment period.
For patients rolling over from Study 12709A, the Baseline Visit will be performed the same 
day as the Week 12 (Completion) Visit of Study 12709A. The ICF must be signed before any 
Study 13546A-related activities take place. The eligibility criteria should be confirmed based 
on the evaluation of the latest data available in Study 12709A.
For 12709A patients, values from assessments and procedures (efficacy/safety, including 
blood/urine samples and use of concomitant medication) performed at the Completion Visit 
(Visit 12) in Study 12709A will be the Baseline Visit values in Study 13546A (detailed in 
Panel 2 and section 11.1.2). Please note that the hormones laboratory tests are specific for the 
13546A study and will have to be collected using a separate kit at the same time as collecting 
the blood samples required by the 12709A protocol. Assessments that are not part of the 
Completion visit in 12709A (that is, examinations, Tanner staging, and menstrual cycle) will

be performed as part of the 13546A Baseline Visit. Patients eligible for entering the open-label 
period will start IMP (vortioxetine) at the Baseline Visit. Patients will start with 5 mg/day as 
detailed in section 6.1.
The schedule of assessments during the open-label period is described in Panel 2.
8.4
Randomization Visit (Visit 8)
The double-blind period starts with the Randomization Visit (8) at Week 12. Patients who 
fulfil the randomization criteria (section 5.4) will be randomly assigned via a centralized 
randomization system to receive vortioxetine or placebo in a 1:1 ratio. 
Patients rolling over from Study 12712A need to fulfil inclusion/exclusion criteria detailed in 
sections 5.3. At the Randomization Visit, de novo patients and rollover patients from Study 
12709A undergo evaluation of randomization criteria, and evaluation of efficacy and safety 
assessments as per Panel 3. Patients who do not meet the randomization criteria will be 
withdrawn from the study and complete an early withdrawal visit.
For 12712A-patients, last available values from assessments and procedures (efficacy/safety, 
and use of concomitant medication) performed at either Visit 7 (Week 8) and/or Visit 8 (Week 
10), or Visit 9 (Week 12) in Study 12712A will be the Randomization Visit values for this 
study. For patients who rollover at Visit 7 or Visit 8, weight, height, Tanner staging, menstrual 
cycle, and examinations should be done at the Randomization Visits (detailed in Panel 3 and 
section 11.1.2).
The schedule of assessments during the Double-blind Period is described in Panel 3.
8.5
Withdrawal Visit
Open-label Period: Patients who withdraw from the study prior to Visit 8 will be asked to 
attend a Withdrawal Visit, if at all possible. The visit must be scheduled as soon as possible 
after withdrawal. Patients who withdraw from treatment will also be asked to attend a Safety 
Follow-up Visit.
Patients who do not fulfil randomization criteria for remission or adequate response at 
Week 10 and/or Week 12 will be withdrawn from the study and will complete an early 
Withdrawal Visit.
Double-blind Period: Patients who withdraw from the study prior to the Completion Visit after 
26 weeks of treatment in the double-blind period will be asked to attend a Withdrawal Visit, if 
at all possible. The visit must be scheduled as soon as possible after withdrawal. Patients who 
withdraw from the study will also be asked to attend a Withdrawal Visit (Visit 17, where both 
efficacy and safety are assessed).

No new information will be collected from patients who withdraw from the study, except 
information collected in relation to the scheduled Withdrawal Visit or needed for the follow-
up of adverse events (section 10.5).
The reason for withdrawal must be recorded in the eCRF.
For a patient and/or the patient’s parent(s)/legal representative(s) who withdraw consent:
if the patient and/or the patient’s parent(s)/legal representative(s) withdraw consent during a 
visit and then agree(s) to it being the final visit, the investigator will complete the visit as a 
Withdrawal Visit and all the data collected up to and including that visit will be used
if the patient and/or the patient’s parent(s)/legal representative(s) withdraw(s) consent 
during a telephone conversation, the investigator will ask the patient if he or she will attend 
a Withdrawal Visit. If the patient:
agrees to attend a Withdrawal Visit, all the data collected up to and including that visit 
will be used
refuses to attend a Withdrawal Visit, the investigator should attempt to follow the 
patient’s safety and future treatment; any information collected will only be recorded in 
the patient’s medical records
if the patient and/or the patient’s patients/legal representative explicitly request(s) that the 
patient’s data collected from the time of withdrawal of consent onwards not be used, this 
will be respected
8.6
Safety Follow-up Visit
A safety follow-up is conducted to capture SAEs that occur during the Safety Follow-up 
Period as well as to follow-up on the outcome of adverse events ongoing at the end of the 
treatment period.
Safety follow-up for the open-label period is applicable for patients who are withdrawn or do 
not continue to the double-blind period: This can be a telephone contact, unless an SAE has 
occurred since the last visit or unless there was a clinically significant abnormal safety 
laboratory test value at the last visit. In such cases, safety follow-up(s) must be scheduled to 
allow for a medical examination and/or blood sampling. Further safety follow-up visits beyond 
30 days may be needed as judged by the investigator (if further safety follow-up visits are 
performed, these must be recorded in the patient’s medical record, and not in the eCRF).
Safety follow-up for the double-blind period: This visit should be scheduled approximately 
30 days after the last dose of IMP. This can be a telephone contact, unless an SAE has 
occurred since the last visit or unless there was a clinically significant abnormal safety 
laboratory test value at the last visit. In such cases, safety follow-up(s) must be scheduled to 
allow for a medical examination and/or blood sampling. Further safety follow-up visits beyond 
30 days may be needed as judged by the investigator (if further safety follow-up visits are 
performed, these must be recorded in the patient’s medical record, and not in the eCRF).

For adverse events that were ongoing at the end of the treatment period and that resolved 
during the Safety Follow-up Period, the stop date must be recorded. For non-serious adverse 
events still ongoing at the safety follow-up, the Ongoing Adverse Event checkbox on the 
Adverse Event Form must be ticked. SAEs must be followed until resolution or the outcome is 
known.
Patients with a clinical safety laboratory test value that was out-of-range at the Completion/
Withdrawal Visit and judged clinically significant must be followed according to accepted 
medical standards for up to 30 days or until the value normalizes or stabilizes or a diagnosis or 
a reasonable explanation has been established. For these patients, safety follow-up visits must 
be scheduled to allow for a medical examination and/or blood sampling. The investigator must 
decide whether further safety follow-up visits are required after 30 days. If further safety 
follow-up visits are made, these must be documented in the patient’s medical record and not in 
the eCRF.
Patients who withdrew due to elevated AST or ALT values (see section 5.5) should be 
followed until the values normalize or stabilize or a diagnosis or a reasonable explanation has 
been established (see section 10.5).
The safety follow-up for patients who withdraw consent must be performed, if at all possible; 
any information collected will only be recorded in the patients’ medical records.
8.7
End-of-study Definition
The end of the study for an individual patient is defined as the last protocol-specified contact 
with that patient. The overall end of the study is defined as the last protocol-specified contact 
with the last patient ongoing in the study.
This study will be terminated if the result of the currently ongoing placebo-controlled, 
short-term study (12709A) in children is negative (that is, if vortioxetine fails to show a 
significant difference from placebo in acute treatment). In case of study termination, the 
participating patients will be treated at the discretion of the investigator in line with clinical 
practice.
9
Assessments
Timing and frequency of all assessments are specified in Panel 2 (open-label period) and 
Panel 3 (double-blind period).
Lundbeck reserves the right to use external quality oversight methods of all study assessment 
tools to ensure the validity of the diagnosis and the severity of the illness.

Screening and Baseline Procedures and Assessments
9.1.1
Demographics and Baseline Characteristics
Prior to enrolling a patient in the study, the investigator must ascertain that the patient 
meets the selection criteria.
At the Screening Visit (concerns de novo patients only), the following will be recorded or 
assessed:
Relevant medical, social, psychiatric and neurological history including MDD history, time 
of diagnosis, treatment type and outcome (response and tolerability)
History of stimulant medication, if any
Demographics: age, sex, and race. In order to determine the exact age at any point in the 
study, full date of birth will be collected where permitted by local regulations.
Family psychiatric history
Traumatic life events
Height, weight
Puberty status (Tanner staging)
Menstrual cycle
9.1.2
Diagnostic Assessments
The K-SADS-PL will be used as screening assessment. The diagnosis of MDD (according 
to DSM-5™) will be established via a psychiatric evaluation. The K-SADS-PL will be used 
to confirm the diagnosis of MDD and to assess possible psychiatric co-morbidities.
The K-SADL-PL will be administered in local language. Only scales provided by Lundbeck
that have been validated in the language to which they have been translated will be used in
this study.
9.1.3
The Kiddie-Schedule for Affective Disorders and Schizophrenia for School-aged 
Children, Present and Lifetime version (K-SADS-PL).
The K-SADS-PL26 is a semi-structured diagnostic interview designed to assess current and 
past episodes of psychopathology in children and adolescents. The K-SADS-PL consists of 
interviews with the parent(s), the child, and information from other sources (for example, 
school report). The unstructured introductory interview establishes a rapport with the parent(s) 
and the child, the screening interview (comprising 82-items to survey key symptoms for 
current and past episodes of 20 different diagnostic areas) provides a diagnosis, and responses 
to skip-out criteria determine whether additional interviewing is necessary. If necessary, the 
additional interview consists of a maximum of five diagnostic supplements (affective 
disorders, psychotic disorders, anxiety disorders, behavioural disorders, and substance abuse, 
eating, and tic disorders). The K-SADS-PL items are scored using a 2-point or a 3-point scale

from 1 (no symptoms) to 3 (threshold levels of symptomatology). It takes approximately 180 
minutes to complete both K-SADS-PL interviews (parent(s) and child).
9.1.4
K-SADS-PL Rater Qualification and Certification
The K-SADS-PL should be administered by a rater who has adequate experience with 
paediatric patients with MDD. The rater should be a psychiatrist or doctor of osteopathy (DO) 
specialised in child and adolescent psychiatry, or a clinical paediatric (neuro-) psychologist 
involved in clinical practice.
Any exceptions must be discussed and approved by Lundbeck.
Only raters who have been certified in a study-specific Rater Certification Programme will be 
authorized to rate in this study. Documentation of training and certification will be delivered to 
the raters for archiving in the investigator trial master file (TMF). No patient may be rated 
before the documentation has been delivered.
New raters joining the study will be trained and certified locally using the same certification 
processes.
9.1.5
Drug and Alcohol Screen
It is not mandatory to screen for drugs and/or alcohol. However, it can be performed at any 
visit during the open-label and double-blind periods, at the discretion of the investigator. The 
blood and urine drug screen samples will be analysed at the central laboratory.

Use of COA Tools
The following clinician-rated electronic assessment tools will be used and accessed via a tablet 
provided by Signant Health, called a Rater Station:
CDRS-R – assessing depressive symptoms
CGI-S/I – assessing clinical global impression
Detailed instructions on how to administer the scales and how to score using the scales will be 
provided to the site in a Rater Station Site Manual.
The CDRS-R will be administered in the local language. Only scales provided by Lundbeck 
that have been validated in the language to which they have been translated will be used in this 
study.

9.2.1.2
Children depression rating scale revised version (CDRS-R)
The CDRS-R27 is a clinician-rated scale to measure the severity of depression of children and 
adolescents. The CDRS-R is rated by a clinician following interviews with the child and 
parent(s) and consists of 17 items: 14 items rate verbal observations, and 3 items rate 
nonverbal observations (tempo of language, hypoactivity, and nonverbal expression of 
depressed affect). Items are rated for severity on a 7-point scale (1 to 7) for 14 items, and on a 
5-point scale (1 to 5) for 3 items (sleep disturbance, appetite disturbance, and listless speech). 
The total score ranges from 17 (normal) to 113 (severe depression). The CDRS-R can be 
administered by a clinician after a training session. It takes approximately 20 to 30 minutes to 
administer and rate the CDRS-R.
9.2.1.3
Clinical Global Impression Scales (CGI-S/I)
The CGI28 was developed to provide global measures of the severity of a patient’s clinical 
condition and improvement or worsening during clinical studies.
The clinician will use the scale to assess depressive symptoms.
The CGI consists of two clinician-rated subscales: severity of illness (CGI-S) and global 
improvement (CGI-I).
The CGI-S provides the clinician’s impression of the patient’s current state of mental illness. 
The clinician uses his or her clinical experience of this patient population to rate the severity 
of the patient’s current mental illness on a 7-point scale ranging from 1 (Normal - not at all ill) 
to 7 (among the most extremely ill patients).
The CGI-I provides the clinician’s impression of the patient’s improvement (or worsening). 
The clinician assesses the patient’s condition relative to Randomization (as the CGI-I only will 
be assessed in the Double-blind period) on a 7-point scale ranging from 1 (very much 
improved) to 7 (very much worse). In all cases, the assessment should be made independent of 
whether the rater believes the improvement is drug-related or not.
An experienced clinician can use the CGI after a short training session. It takes 1 to 2 minutes 
to score the CGI after a clinical interview.
9.2.1.4
Rater Qualification
The CDRS-R and CGI-S/I scales should only be administered by a rater who has adequate 
experience with paediatric patients with MDD and who has adequate experience in rating 
scales. The rater should be a psychiatrist or DO specialised in child and adolescent
psychiatry, or a clinical paediatric (neuro-) psychologist involved in clinical practice.
The CGI-S/I should be administered by the investigator responsible for the patient. The 
investigator must be a psychiatrist or DO specialised in child and adolescent psychiatry that 
has adequate experience with paediatric patients with MDD.

For each individual patient, the same certified rater should rate the patient. For unforeseen 
circumstances, certified back-up raters should be available throughout the study.
9.2.2
Patient and/or Parent Reported Outcomes (PROs)
The following electronic PRO will be completed by the patient on the Rater Station:
PQ-LES-Q29: designed to assess patient’s satisfaction with life
9.2.2.1
Paediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-
LES-Q)
The PQ-LES-Q29 is a patient-rated scale designed to assess satisfaction with life. It is an
adaptation of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), which
is used to measure quality of life in adults. The PQ-LES-Q consist of 15 items, item 1 to 14 
assess the degree of satisfaction experienced by patients in various areas of daily functioning 
and item 15 allows subjects to summarize their experience in a global rating.
Each item is rated on a 5-point scale from 1 (very poor) to 5 (very good). The total score range
of item 1 to 14 is 14 to 70, with higher scores indicating greater satisfaction. It takes 5 to 10
minutes to complete the scale.
The site staff should instruct patients on how to use the Rater Station. On-screen instructions 
on how to complete the scale will be available in the Rater Station.
9.3
Pharmacokinetic Assessments
Blood samples (1 mL) for IMP analysis will be collected in ethylenediamine tetra acetic acid 
(EDTA) tubes simultaneously with clinical safety lab samples. The blood sampling and 
handling procedures are described in the study-specific Laboratory Specification Manual.

9.4
Safety Assessments
9.4.1
Adverse Events
The patients will be asked a non-leading question (for example, “how do you feel?”, “how 
have you felt since your last visit?”) at each visit, starting at the Screening Visit. AEs 
(including worsening of concurrent disorders, new disorders, and pregnancies) either observed 
by the investigator or reported spontaneously by the patient will be recorded, and the 
investigator will assess the seriousness and the intensity of each AE and its relationship to the 
IMP. Results from relevant tests and examinations, such as clinical safety laboratory tests, 
vital signs, and ECGs, or their corresponding conditions will also be recorded as AEs if 
considered by the investigator to be clinically significant.
See chapter 10 for further information on AEs.

Page 58 of 85
The investigator must review (initial and date) the results of the clinical safety laboratory tests 
as soon as possible after receipt of those results. Out-of-range values must be interpreted by 
the investigator as “not clinically significant” or “clinically significant” with a comment 
concerning the planned follow-up. Tests for clinically significant out-of-range values must be 
repeated, or an appropriate clinical follow-up must be arranged by the investigator and 
documented on the laboratory report, until the value has stabilized or until the value has 
returned to a clinically acceptable value (regardless of relationship to the IMP). A patient with 
a value that is out-of-range at the Completion Visit (Week 26 of double-blind period) or 
Withdrawal Visit and considered clinically significant must be followed in accordance with 
usual clinical practice for up to 30 days or until the value normalizes or stabilizes or a 
diagnosis or reasonable explanation has been established. Any out-of-range values followed 
after the last protocol-specified contact with the patient will be documented in the patient’s 
medical records.
Any out-of-range clinical safety laboratory test value considered clinically significant by the 
investigator must be recorded as an AE on an Adverse Event Form.
The central laboratory will be notified by the sponsor when the biological samples may be 
destroyed.
9.4.3
Vital Signs
The investigator may appoint a designee to measure vital signs, provided this is permitted 
according to local regulations and provided the investigator has trained the designee how to 
measure vital signs. The investigator must take responsibility for reviewing the findings.
Blood pressure and pulse rate will be measured using a standard digital meter with adequate 
cuff size after the patient has rested for at least 5 minutes in a supine position. The patient 
must then be instructed to change from a supine to a standing position in a manner that 
includes passing through a sitting position before assuming an upright position. Blood pressure
and pulse rate will be measured after the patient has been standing for at least 1 minute but no 
longer than 5 minutes.
Any out-of-range vital sign considered clinically significant by the investigator must be 
recorded as an AE on an Adverse Event Form.
9.4.4
Height and Weight
The patient’s height will be measured, without shoes.
The patients will be weighed wearing light clothing and no shoes. A similar amount of 
clothing must be worn on each occasion.
Any weight change considered clinically significant by the investigator must be recorded as an 
AE on an Adverse Event Form.

Electrocardiograms (ECGs)
A standard 12-lead ECG will be recorded using digital ECG recording equipment provided to 
the investigator or, upon agreement, to an external cardiology centre. The ECGs will be 
transferred digitally to a central ECG laboratory for evaluation, where they will be reviewed 
by a paediatric cardiologist. The investigator will be provided with the results and a 
cardiologic interpretation of the ECG from the central ECG laboratory.
The results from the central ECG laboratory will include the RR, PR, QRS, QT, QTc, and 
QTcF intervals.
The investigator has the final decision on the interpretation of the ECG results. Any abnormal 
ECG result or out-of-range ECG parameter value considered clinically significant by the 
investigator must be recorded as an AE on an Adverse Event Form.
9.4.6
Physical and Neurological Examinations
The investigator may appoint a designee to be primarily responsible for performing the 
physical examinations, provided this is permitted according to local regulations. The 
investigator must take responsibility for reviewing the findings. Whenever possible, the same 
individual should perform all the physical examinations.
The physical examination must, at a minimum, include an examination of appearance, 
extremities, skin, head, neck, eyes, ears, nose, throat, lungs, chest, heart, abdomen, and 
musculoskeletal system and must be performed by a physician or physician assistant. If there 
is no physical examination at the Baseline Visit, the examination at the Screening Visit will be 
considered the baseline physical examination.
The neurological examination must be performed by a physician.
Any abnormal finding or out-of-range value considered clinically significant by the 
investigator must be recorded as an AE on an Adverse Event Form.
9.4.7
Tanner Staging
Tanner staging is a scale for assessing physical development and sexual maturity during onset 
and progress of puberty.
The scale includes 5 stages of pubertal changes (called Tanner stages) separate for males and 
for females.
For female the 5 stages of maturation are recognized by assessing pubic hair and breast 
development. For male the 5 stages of maturation are recognized by assessing pubic hair, 
growth of penis and testicles. Post-puberty is defined as a Tanner stage = 5 in both of observed 
criteria.

The evaluation of Tanner stage will be performed by physician or trained nurse - they will be 
provided with figures depicting the somatic changes and tables describe these changes in 
words to facilitate the staging.
Tanner staging will be performed in conjunction with the physical examination according to 
the schedule displayed in Panel 2 and Panel 3.
9.4.8
Menstrual Cycle
The following will be recorded: 

Age of menarche 

The length of the menstrual cycle (number of days from the first day of menstruation to 
the day before the first day of the next menstrual period)

Menstrual cycle regularity
9.4.9
General Behaviour Inventory (GBI) 10-Item Mania Scale
The GBI 10-item mania scale32 is a parent- and subject-rated scale designed to screen for 
manic symptoms in children and adolescents. The ten items are rated on a 4-point scale 
from 0 (never or hardly ever) to 3 (very often or almost constantly). The total score ranges 
from 0 to 30, with higher scores indicating greater pathology. It takes approximately 
5 minutes to complete the GBI 10-item mania scale.
The parent-rated scale is validated and appropriate for the use in children and adolescents 
with psychiatric disorders.33 The subject-rated scale is validated only for patients in the age 
group 10 to 17 years.34 Therefore, only the parent-rated scale will be used in this study.
The GBI will be administered in the local language. Only scales provided by Lundbeck that 
have been validated in the language to which they have been translated will be used in this 
study.
The site staff should instruct patients and parents/caregivers on how to use the Rater Station, 
On-screen instructions on how to complete the scale will be available in the Rater Station.
9.4.10
Columbia-Suicide Severity Rating Scale (C-SSRS)
The C-SSRS35 is a semi-structured interview developed to systematically assess suicidal 
ideation and behaviour of patients participating in a clinical study. The C-SSRS has 
4 questions addressing suicidal behaviour, 5 questions addressing suicidal ideation, and 
sub-questions assessing the severity.
Different versions of the scale are available: in this study, the “Baseline Screening” version 
will be applied at the Screening Visit and the “Since last visit” version will be applied other 
visits including the C-SSRS.

Page 61 of 85
A version of the C-SSRS specifically developed for the use in children will be applied in the 
study population of children aged 7 to 11 years.
An experienced clinician can use the C-SSRS after a short training session. It takes 
approximately 5 minutes to administer and rate the C-SSRS.
The C-SSRS has 5 questions addressing suicidal ideation. If level 4 or 5 has been answered 
“yes”, a corresponding SAE should be reported.
If the electronic C-SSRS (eC-SSRS) system™is temporarily unavailable on the Rater Station,
a paper version of the C-SSRS (C-SSRS Fallback Form – Baseline/Screening Version) should 
be administered by the investigator. If the eC-SSRS is unavailable at the Screening Visit, the 
paper version should be used; however, the patient will have to return to the site to complete 
the eC-SSRS before he or she may be enrolled in the study. When a C-SSRS Fallback Form
has been used, it must be kept as a source document in the Patient Binder. Data from the 
C-SSRS Fallback Form will not be transcribed in the eCRF.
9.4.10.1
Rater Qualification and Certification
C-SSRS should only be administered by a rater who has adequate experience with paediatric 
patients and who has adequate experience in rating scales. The rater should be a psychiatrist or 
DO specialised in child and adolescent psychiatry, or a clinical paediatric (neuro-) 
psychologist involved in clinical practice. Any exceptions must be discussed with and 
approved by Lundbeck.
Only raters who have been certified through the scale author’s website will be authorized to
rate in this study. Documentation of training and certification will be delivered to the raters for 
archiving in the investigator TMF. No patient may be rated before the documentation has been 
delivered.
New raters joining the study will be trained and certified locally using the same certification 
process.

Total Volume of Blood Drawn and Destruction of Biological Material
The total volume of blood drawn during the study will be approximately 39.5 mL (20 mL in 
the open-label period and 19.5 ml in the double blind period) for de novo patients.
Additional blood samples may be required if the original blood samples are not viable or if 
re-testing is required.
9.7
Treatment Compliance
It is the responsibility of the investigator to account for all IMP (refer to IMP accountability 
section 6.5). The investigator or her/his designee must agree not to dispense any IMP to any 
person, except patient/parents included in the study and he/she/they must further agree only to 
use IMP in accordance with protocol.
In addition, measures of the blood concentration of vortioxetine will indicate whether patient 
has been overall compliant throughout the study.
10 Adverse Events
10.1
Definitions
10.1.1
Adverse Event Definitions36
Adverse event – is any untoward medical occurrence in a patient or clinical study patient 
administered a medicinal product and which does not necessarily have a causal relationship 
with this treatment.
An adverse event can therefore be any unfavourable and unintended sign (including clinically 
significant out-of-range values from relevant tests, such as clinical safety laboratory tests, vital 
signs, ECGs), symptom, or disease temporally associated with the use of a medicinal product, 
regardless of whether it is considered related to the medicinal product.
It is Lundbeck policy to collect and record all adverse events, including pre-treatment adverse 
events, that is, those that start after the patient has signed the Assent Form/Informed Consent 
Form and prior to the first dose of IMP.

Study 13546A – Clinical Study Protocol
Page 63 of 85
Serious adverse event (SAE) – is any adverse event that:
results in death
is life-threatening (this refers to an event in which the patient was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
had it been more severe)
requires inpatient hospitalization or prolongation of existing hospitalization
results in persistent or significant disability/incapacity
is a congenital anomaly/birth defect
is medically important (this refers to an event that may not be immediately life-threatening
or result in death or hospitalization, but may jeopardize the patient or may require 
intervention to prevent any of the SAEs defined above)
Examples of medically important events are intensive treatment for allergic bronchospasm; 
blood dyscrasia or convulsions that do not result in hospitalization; or development of drug 
dependency or drug abuse.
Planned hospitalizations or surgical interventions for a condition that existed before the patient 
signed the Informed Assent/Consent Form and that did not change in intensity are not adverse 
events. Emergency room visits that do not result in admission to the hospital are not 
necessarily SAEs; however, they must be evaluated to determine whether they meet any of the 
SAE definitions (for example, life-threatening or other serious [medically important] event).
Non-serious adverse event – is any adverse event that does not meet the definition of an SAE.
If there is any doubt as to whether an AE meets the definition of an SAE, a conservative 
viewpoint must be taken, and the AE must be reported as an SAE.
Suspected unexpected serious adverse reaction (SUSAR) – is any AE that is assessed as 
serious, unexpected (its nature or intensity is not consistent with the current version of the 
Investigator’s Brochure for vortioxetine15 and related to a medicinal product by either the 
investigator or Lundbeck. 
Overdose – is a dose taken by a patient that exceeds the dose prescribed to that patient. Any 
overdose (and associated signs/symptoms) must, at a minimum, be recorded as a non-serious 
AE.
10.1.2
Adverse Event Assessment Definitions
Assessment of Intensity
The investigator must assess the intensity of the adverse event using the following definitions, 
and record it on the Adverse Event Form:
Mild – the adverse event causes minimal discomfort and does not interfere in a significant 
manner with the patient’s normal activities.

Study 13546A – Clinical Study Protocol
Page 64 of 85
Moderate – the adverse event is sufficiently uncomfortable to produce some impairment of 
the patient’s normal activities.
Severe – the adverse event is incapacitating, preventing the patient from participating in the 
patient’s normal activities.
Assessment of Causal Relationship
The investigator must assess the causal relationship between the adverse event and the IMP 
using the following definitions, and record it on the Adverse Event Form and the Serious 
Adverse Event Form (if applicable):
Probable – the adverse event has a strong temporal relationship to the IMP or recurs on 
rechallenge, and another aetiology is unlikely or significantly less likely.
Possible – the adverse event has a suggestive temporal relationship to the IMP, and an 
alternative aetiology is equally or less likely.
Not related – the adverse event has no temporal relationship to the IMP or is due to 
underlying/concurrent disorder or effect of another drug (that is, there is no causal 
relationship between the IMP and the adverse event).
An adverse event is considered causally related to the use of the IMP when the causality 
assessment is probable or possible. 
Assessment of Outcome
The investigator must assess the outcome of the adverse event using the following definitions, 
and record it on the Adverse Event Form and the Serious Adverse Event Form (if applicable):
Recovered – the patient has recovered completely, and no symptoms remain.
Recovering – the patient’s condition is improving, but symptoms still remain.
Recovered with sequelae – the patient has recovered, but some symptoms remain (for 
example, the patient had a stroke and is functioning normally, but has some motor 
impairment).
Not recovered – the patient’s condition has not improved and the symptoms are unchanged 
(for example, an atrial fibrillation has become chronic).
Death
10.2
Pregnancy
Although not necessarily considered an adverse event, a pregnancy in a patient in the study 
must be recorded on an Adverse Event Form, as well as on a Pregnancy Form (paper), even if 
no adverse event associated with the pregnancy has occurred. Pregnancies must be reported to 
Lundbeck using the same expedited reporting timelines as those for SAEs.
An uncomplicated pregnancy should not be reported as an SAE; hospitalization for a normal 
birth should not be reported as an SAE. If, however, the pregnancy is associated with an SAE, 
the appropriate serious criterion must be indicated on the Serious Adverse Event Form.

Page 65 of 85
Examples of pregnancies to be reported as SAEs (medically important) are spontaneous 
abortions, stillbirths, and malformations.
The investigator must follow-up on the outcome of the pregnancy and report it on a Pregnancy 
Form (paper). The follow-up must include information on the neonate at least up until the age 
of 1 month.
10.3
Recording Adverse Events
Adverse events (including pre-treatment adverse events) must be recorded on an Adverse 
Event Form. The investigator must provide information on the adverse event, preferably with a 
diagnosis, or at least with signs and symptoms; start and stop dates (and start and stop time if 
the adverse event lasts less than 24 hours); intensity; causal relationship to the IMP; action 
taken; and outcome. If the adverse event is not related to the IMP, an alternative aetiology 
must be recorded, if available. If the adverse event is an overdose, the nature of the overdose 
must be stated (for example, medication error, accidental overdose, or intentional overdose). If 
the intensity changes during the course of the adverse event, this must be recorded on the AE 
Intensity Log.
If the adverse event is serious, this must be indicated on the Adverse Event Form. 
Furthermore, the investigator must fill out a Serious Adverse Event Form and report the SAE 
to Lundbeck immediately (within 24 hours) after becoming aware of it (see section 10.4).
If individual adverse events are later linked to a specific diagnosis, the diagnosis should be 
reported and linked to the previously reported adverse events.
10.4
Reporting Serious Adverse Events (SAEs)
The investigator must report SAEs to Lundbeck immediately (within 24 hours) after becoming 
aware of them by completing a Serious Adverse Event Form.
The initial Serious Adverse Event Form must contain as much information as possible and, if 
more information about the patient’s condition becomes available, the Serious Adverse Event 
Form must be updated with the additional information.
If the investigator cannot report the SAE in Rave®, then he or she must complete and sign the 
Serious Adverse Event Fallback Form and send it to:

Lundbeck will assume responsibility for reporting SUSARs to the authorities in accordance 
with local requirements. In those Member States of the European Union that have 
implemented the European Union Clinical Trials Directive37 and in Norway, Liechtenstein, 
and Iceland, that is, in the countries where unblinded expedited safety reporting is required, 
Lundbeck will also assume responsibility for reporting SUSARs to the IECs.
Lundbeck will assess the expectedness of SAEs and inform the investigator(s) about SUSARs 
in the blinded SUSAR listings.
10.5
Treatment and Follow-up of Adverse Events
Patients with adverse events must be treated in accordance with usual clinical practice at the 
discretion of the investigator.
The investigator must follow-up on non-serious adverse events until resolution or the Safety 
Follow-up Visit/Contact, whichever comes first. At the Safety Follow-up Visit/Contact, 
information on new SAEs, if any, and stop dates for previously reported adverse events must 
be recorded.
The investigator must follow-up on all SAEs until the patient has recovered, stabilized, or 
recovered with sequelae, and report to Lundbeck all relevant new information using the same 
procedures and timelines as those for the initial Serious Adverse Event Form.
SAEs that are spontaneously reported by a patient to the investigator after the Safety 
Follow-up Visit/Contact must be handled in the same manner as SAEs that occur during the 
study. These SAEs will be recorded in the Lundbeck safety database.
The investigator must follow-up on patients with a clinically significant out-of-range clinical 
safety laboratory test value at the Primary Outcome (Week 26 of double-blind period) or 
Withdrawal Visit in accordance with usual clinical practice be scheduled for a Safety 
Follow-up Visit to allow for a medical examination and/or blood sampling (see section 8.6). If 
further follow-up visits are made, these must be documented in the patient’s medical records 
and not in the eCRF.
Patients who withdraw due to an elevated AST or ALT value (see section 5.5) must be 
followed until the values normalize or stabilize or a diagnosis or a reasonable explanation has 
been established. Additional medical examinations (for example, ultrasound scanning and/or 
sampling for serology, conjugated bilirubin, prothrombin time) should be considered. A 
gastroenterology or hepatology consultation should also be considered.

The DMC is an independent, external committee which includes child and adolescent 
psychiatrists. The DMC review and evaluate safety data on an ongoing basis in addition to 
cumulative safety data. The DMC will have access to unblinded data and will provide 
recommendations on study continuation, modification or termination. Members of the DMC 
will not be involved in other study-related tasks. The DMC procedures are described in the 
Data Monitoring Committee Charter.
11 Data Handling and Record Keeping
11.1
Data Collection
11.1.1
Electronic Case Report Forms (eCRFs)
eCRFs will be used to collect all the data related to the study, except the external data 
described in section 11.1.5.
The eCRFs use third party software (Rave®) to capture data via an online system on a 
computer. When the investigator enters data in the eCRF (ideally during the visit or as soon as 
possible, <3 days thereafter), the data will be recorded electronically in a central database over 
encrypted lines, and all entries and modifications to the data will be logged in an audit trail. 
Access to the system will only be granted after appropriate and documented training. Written 
instructions for using the system will be provided along with the training.
Electronic signatures will be used where signatures are required on pages and/or visits. 
Automated data entry checks will be implemented where appropriate; other data will be 
reviewed and evaluated for accuracy by the sponsor and/or representatives from specify CRO. 
All entries, corrections, and changes must be made by the investigator or a delegate.
11.1.2
Data Transfer for Rollover Patients (Studies 12709A and 12712A)
Data available in the eCRF for Studies 12709A and 12712A will be transferred to the 
Study 13546A eCRF where possible, in accordance with Panel 2 and Panel 3. The data to be 
transferred from Studies 12709A and 12712A eCRF to the Study13546A eCRF will be 
specified in the eCRF Completion Guidelines.
11.1.3
External Data From Study 12709A and Study 12712A
All external data pertaining to the rollover visit assessments (as detailed in Panel 2 and 
Panel 3) will be transferred to the 13546A Study.

Patient Binders eCRF
11.1.4.1
Use of Patient Binders
The Patient Binder contains different types of source documents, including paper versions of 
any COAs and PROs completed as a fall-back solution (see below). A ballpoint pen with 
waterproof ink must be used to enter information in the Patient Binder.
11.1.4.2
Clinical Outcome Assessments (COAs)
The Patient Binder contains the paper version of the following COA tool: K-SADS-PL, to be 
completed by the raters. The data will be transcribed to the Scoring Sheets in the eCRF by the 
investigator or a delegate; the raters must verify that all the entries are accurate and correct by 
signing and dating the relevant pages.
A paper version of any electronic clinical outcome assessments (eCOAs) (other than K-SADS-
PL) or ePRO will only be completed as a fall-back solution if the electronic Rater Station 
system is not available.
In case when paper scales are used, the patients and parents will be asked to complete the 
PROs in their local language. The responses may only be corrected by the patient/parent.
11.1.4.3
Serious Adverse Event Fallback Forms
Serious Adverse Event Fallback Forms must be used when the eCRF cannot be accessed.
11.1.5
External Data
All electronic data will be transferred using a secure method accepted by Lundbeck.
The clinical safety laboratory test data will be transferred by ICON laboratory.
The following electronic data will be transferred by ICON and kept in a secure designated 
storage area outside the eCRF:

Retention of Study Documents at the Site
11.2.1
eCRF Data
If a site closes before the study has been completed, the investigator will continue to have 
read-only access to the eCRF until the study has been completed. After the study has been 
completed, all user access to the eCRF will be revoked. Renewed access to the eCRF will be 
given if corrections or updates to the database are required.
At the end of the study, the site will be provided with all data related to the site (including 
eCRF data, queries, and the audit trail) using a secure electronic medium; the secure storage of 
these data at the site is the responsibility of the investigator. When confirmation of receipt of 
the data has been received from all sites, all user access to the eCRF will be revoked. If, for 
some reason, the data are not readable for the full retention period (25 years or in accordance 
with national requirements, whichever is longer), the investigator may request that the data be 
re-sent.
11.2.2
Other Study Documents
The investigator must keep the investigator’s set of documents in the investigator TMF for at 
least 25 years after the Clinical Study Report has been approved or in accordance with national 
requirements, whichever is longer. Lundbeck will remind the investigator in writing of this 
obligation when the Clinical Study Report Synopsis is distributed to the site.
If off-site storage is used, a study-specific binder will remain at the site after the other 
study-specific documents have been shipped for off-site storage. This binder is considered part 
of the investigator TMF and must be kept in a secure place by the site for the required period 
of time. The binder must contain, at a minimum, the following documents: a copy of the 
Investigator TMF Index, a certified copy of the Patient Identification Code List, and a 
Retrieval Form.
When the required storage period has expired, the documents may be destroyed in accordance 
with regulations.
12 Monitoring Procedures
The monitoring strategy for the study foresees a risk-based monitoring approach, in line with 
the relevant FDA and EMA recommendations, and will be described in detail by the 
study-specific risk-based Monitoring Plan, including remote eCRF review and centralised 
monitoring of study data.
Prior to allowing patients to participate in the study, the investigator must sign a source data 
agreement that identifies the source documents (original documents, data, and records) at the 
site. The document will also list which data may be recorded directly on the eCRFs.

If the investigator does not have a patient’s medical records, the investigator must attempt to 
obtain copies or a written summary of relevant medical records from the doctor who had 
treated the patient earlier and include the pertinent documentation in the patient’s medical 
records at the site. The investigator must obtain medical records documenting the patient’s 
lifetime MDD episodes and general medical history for the 3 months prior to the study.
During the study, the clinical research associate (CRA) will visit the site to ensure that the 
protocol is being adhered to and that all issues are being recorded, to perform source data 
verification, and to monitor IMP accountability. The visit intervals will depend on the outcome 
of the remote monitoring of the eCRFs, the site’s recruitment rate, and the compliance of the 
site to the protocol and Good Clinical Practice. In addition, the CRA will be available for 
discussions by telephone.
Source data verification requires that the CRA be given direct access to all the source 
documents. Direct access includes permission to examine and verify any records that are 
important for the evaluation of the study.
13 Audits and Inspections
Authorized personnel from Medical, Regulatory and Clinical Quality Assurance, 
H. Lundbeck A/S, and quality assurance personnel from business partners may audit the study 
at any time to assess compliance with the protocol and the principles of Good Clinical 
Practice and all other relevant regulations.
The investigator must be aware that representatives from regulatory authorities may also wish 
to inspect source data, such as medical records. The investigator must notify Lundbeck, 
without delay, of an announced inspection by a regulatory authority.
During audits and inspections, the investigator must permit direct access to all the source 
documents, including medical records and other documents pertinent to the study.
During audits and inspections, the auditors and inspectors may request relevant parts of 
medical records. No personal identification apart from the screening or randomization 
numbers will appear on these copies.
Patient data will not be disclosed to unauthorized third parties, and patient confidentiality will 
be respected at all times.
14 Protocol Compliance
Lundbeck has a “no-waiver” policy, which means that permission will not be given to deviate 
from the protocol.
If a deviation occurs, the investigator must inform the CRA and they must review, discuss, and 
document the implications of the deviation.

15 Study Termination
Lundbeck or a pertinent regulatory authority may terminate the study or part of the study at 
any time. The reasons for such action may include, but are not limited to:
safety concerns
proven lack of efficacy of the IMP in the children’s study (12709A)
If the study is terminated or suspended, the investigator must promptly inform the patients and 
ensure appropriate therapy and follow-up. Furthermore, the investigator and/or sponsor must 
promptly inform the IEC or IRB and provide a detailed written explanation. The pertinent 
regulatory authorities must be informed in accordance with national regulations.
If the risk/benefit evaluation changes after the study is terminated, the new evaluation must be 
provided to the IEC or IRB if it will have an impact on the planned follow-up of the patients 
who participated in the study. If so, the actions needed to protect the patients must be 
described.
16 Statistical Methodology
16.1
Responsibilities
ICON Plc will perform the statistical analyses described below.
16.2
Analysis Sets
The following analysis sets will be used to analyse and present the data:
all-patients-enrolled (APES) – all-patients-enrolled to the 12-week open-label, flexible-
dose treatment period who took at least one dose of IMP
all-patients-randomized set (APRS) – all patients randomized to the 26-week double-blind 
treatment period 
full-analysis set (FAS) – all patients randomized to the 26-week double-blind treatment 
period who took at least one dose of double-blind IMP
The patients and data will be classified into the analysis sets according to these definitions at a 
Classification Meeting held after the study database has been released, but before the blind has 
been broken.
16.3
Descriptive Statistics
In general, summary statistics (n, arithmetic mean, standard deviation, median, lower and 
upper quartiles, minimum and maximum values) will be presented for continuous variables. 
Counts and, if relevant, percentages will be presented for categorical variables.

16.4
Patient Disposition
Patient disposition will be summarized by treatment group and in total and will include the 
number of patients in the FAS who completed or withdrew from treatment and from study, as 
well as the number of patients in each analysis set (APES, APRS and FAS).
The disposition data will be summarized for the open-label period (split out by de novo
patients and rollover patients from Study 12709A), and the double-blind period separately.
The number of patients who completed or withdrew from the study will also be summarized 
per period.
The number of patients who withdrew from treatment and from study will be summarized by 
treatment group and primary reason for withdrawal as well as all reasons for withdrawal will 
be presented per period.
16.5
Demographics and Baseline Characteristics
Demographics (sex, age, and race), baseline characteristics (height, weight and BMI), baseline 
efficacy variables, and other disease characteristics will be summarized by treatment group 
and in total. Patient disposition and demographics will be summarized using descriptive 
statistics.
16.6
Recent and Concomitant Medication
Recent and concomitant medication will be summarized by anatomical therapeutic chemical 
(ATC) code and generic drug name by treatment group and in total.
16.7
Exposure and Compliance
Exposure and compliance will be calculated per patient and summarized by treatment group.
Exposure will be defined as the number of days between the date the last dose of IMP was 
taken and first dose of IMP was taken. Compliance will be defined as the number of days in
which a dose was taken related to the number of days the patient was expected to take IMP as 
per the protocol.
Exposure will be calculated for the open label period, the double-blind relapse period and in 
total.

Efficacy Analyses
16.8.1
General Efficacy Analysis Methodology
All the statistical tests of the efficacy endpoints will be two-sided tests performed at the 5%
significance level and all confidence intervals (CIs) will be 95% CIs, unless otherwise
specified.
The efficacy analyses will be based on the FAS.
16.8.2
Primary Analysis of the Primary Endpoint
The primary efficacy analysis will compare the time to relapse in the double-blind period 
between vortioxetine and placebo treated patients. Relapse will be defined as either a total 
score ≥40 on the CDRS-R with a history of 2 weeks of clinical deterioration, or clinical 
deterioration as judged by the clinician and documented in the eCRF. 
The two treatment groups will be compared using a Cox regression model with exact 
adjustment for ties. 
The regression model will have treatment as fixed factor, CDRS-R Total Score at 
randomization as covariate, and separate baseline hazards for the stratification factor, i.e. the 
patient inclusion source (de novo patients, rollover patients from 12709A, or from 12712A). 
Further details will be given in the SAP.
A one-sided 5% level of significance will be used. Patients not relapsing before Week 26 will 
be censored at Week 26 and patients withdrawing due to other reasons than relapse will be 
censored at time of withdrawal. 
16.8.3
Sensitivity Analyses of the Primary Endpoint
The following sensitivity analyses will be performed:
1.
The primary analysis will be repeated ignoring relapses occurring during the first week, 
two weeks and four weeks of the double-blind period, respectively. 
2.
The number of relapses will be summarized according to relapse criteria: CDRS-R total 
score ≥40 with 2 weeks of clinical deterioration, investigator’s judgement, or both.
3.
Primary analysis will be repeated for the de novo patients and for the (pooled) 12709A 
patients and 12712A patients. 
16.8.4
Analysis of the Secondary Endpoint(s)
The number of relapses will be summarized according to relapse criteria (see section 16.8.2) 
and the relapse over the 26 weeks double-blind period will be analysed using logistic

regression, with treatment and inclusion source as fixed factors and CDRS-R Total Score at 
randomization as covariate.
Secondary efficacy variables (CDRS-R total score, PQ-LES-Q scores, CGI-S and CGI-I) will 
be analysed on an exploratory basis over the 26-week double-blind period by Mixed Model 
Repeated Measurements (MMRM) and analysis of covariance (ANCOVA). For the purpose of 
the analysis the change from baseline in CDRS-R total score, PQ-LES-Q scores, and in CGI-S 
score will be computed. In this respect, baseline will be defined as the start of the double-blind 
period.
For both the MMRM and the ANCOVA, the dependent variable will be the change from 
baseline in CDRS-R total score, change from baseline in PQ-LES-Q scores, change from 
baseline in CGI-S score and the absolute CGI-I score, respectively. In this respect, baseline 
will be defined as the start of the double-blind period.
The MMRM will have treatment, week and inclusion source as fixed factors and the baseline 
score will be added as a covariate. For CGI-I, the score at randomization for the CGI-S will be 
used as covariate. In addition, the interaction between treatment and week and between 
baseline score and week will be included and an unstructured covariance matrix will be 
applied. In this respect, baseline will be defined as the start of the double-blind period.
In the ANCOVA treatment and inclusion source will be included as a fixed factors and the 
respective baseline score will be included as a covariate. For CGI-I, the score at randomization 
for the CGI-S will be used as covariate.
Both the observed cases (OC) and last observation carried forward (LOCF) approach will be 
used.
16.8.5
Testing Strategy
This section is not applicable.
16.8.6
Analysis of the Exploratory Endpoint(s)
No formal exploratory endpoints have been defined.
On an exploratory basis, severity of illness, gender and age will be assessed as covariates or to 
generate subgroups for the Cox regression model as described in section 16.8.2.
In addition, descriptive statistics will be used to compare patient populations and treatment 
outcome between the geographical regions.
16.8.7
Pharmacokinetic Analyses
The pharmacokinetic analyses will be based on the pharmacokinetic set (PKS).

The population pharmacokinetics (popPK) of vortioxetine in children will be analysed through 
non-linear mixed effect analysis and will be described in a separate popPK analysis plan. 
16.8.8
Safety Analyses
The safety analyses will be based on the APES and the FAS.
All safety endpoints will be reported for the 12-week open-label period and the 26-week 
double-blind period separately.
16.8.9
Analysis of Adverse Events
Adverse events will be classified according to the time of onset of the adverse event:
pre-treatment adverse event – an adverse event that starts on or after the date the patient 
signed the Informed Consent Form and prior to the date of first dose of IMP
treatment-emergent adverse event (TEAE) – an adverse event that starts or increases in 
intensity on or after the date of first dose of IMP
Adverse events, sorted by system organ class (SOC) and preferred term, will be summarized 
by treatment group.
Allocation of TEAEs to Study Periods
TEAEs may be allocated to study periods (these will be defined in the Statistical Analysis 
Plan).
16.8.10 Analysis of Other Safety Endpoints
Absolute and change from baseline in clinical safety laboratory tests (estradiol for girls, LH, 
FSH), Tanner staging, and effects on menstrual cycle, vital signs, height, weight, BMI and 
ECG parameters will be summarized by treatment group. Potentially clinically significant 
(PCS) safety laboratory test values will be flagged and summarized.
GBI scores (using the 10-item mania subscale), and C-SSRS scores will be summarized using 
descriptive statistics. 
16.9
Interim Analyses
No interim analysis is planned.
16.10 Sample Size and Power
The calculation of power is based on a log-rank test for the time to relapse at a one-sided 5% 
level of significance using SAS Proc Power. A sample size of 80 randomized patients 
(40 patients per treatment group) will provide at least 80% power to find a difference between

vortioxetine and placebo as statistically significant, when expecting cumulative relapse rates at 
0.42 and 0.69 over 26 weeks, respectively corresponding to a hazard-ratio of 2.15. The 
assumption of relapse rates (42% and 69% over 6 months for vortioxetine and placebo, 
respectively) is based on observed rates from a similarly designed relapse-prevention study of 
fluoxetine in paediatric patients with MDD who had an adequate response after 12 weeks of 
acute treatment.14
It is anticipated that approximately 60% of de novo patients enrolled into the open-label period 
will qualify for the double-blind study period. To achieve 80 randomized patients, 150 patients 
are estimated to be enrolled into the study (depending on number and randomization rate of de 
novo and rollover patients).
16.11 Statistical Analysis Plan
A Statistical Analysis Plan describing the handling of data issues and the planned statistical 
analyses in more detail will be prepared by ICON Plc.
The SAP will be finalised prior to the first subject enrolled in the study.
