Title of Study
Interventional, randomised, double-blind, placebo-controlled, active reference (fluoxetine), fixed-dose study of 
vortioxetine in paediatric patients aged 12 to 17 years, with Major depressive disorder (MDD)
Study Sites and Number of Patients Planned
Approximately 100 sites are planned in approximately 15 countries worldwide (specialists, mainly outpatient 
clinics) with patients from the European Union, Europe outside the European Union, North America, and other 
geographical regions.
Approximately 750 patients are planned for enrolment to the 4-week treatment with standardised brief 
psychosocial intervention (BPI) and placebo period (Phase A). At the end of Phase A a total of 600 patients 
(depending on the blinded sample size reassessment, section 18.11) with incomplete improvement are to be 
randomised to the 8 week double-blind Phase B in a 1:1:1:1 ratio to vortioxetine 10 mg, vortioxetine 20 mg, 
fluoxetine 20 mg, or placebo.

Study Methodology
This is an interventional, multi-national, multi-site, randomised, two phase, single- and double-blind, parallel-
group, placebo-controlled, active-reference (fluoxetine), fixed-dose study.
The screening period will be 5 to 15 days followed by a 4-week single-blind period (Phase A) of treatment 
with standardised brief psychosocial intervention and single-blind (patients and parents) placebo. Patients 
who demonstrate an incomplete improvement of depressive symptoms at the end of Week 4 will be 
randomised to a double-blind, 8-week treatment period (Phase B) in a 1:1:1:1 ratio to vortioxetine 10 mg/day, 
vortioxetine 20 mg/day, fluoxetine 20 mg/day, or placebo. Patients and parents are blinded to the time point of 
randomisation to Phase B.
There will be 2 baselines in this study: Baseline A (Week 0) of the 4 week single-blind Phase A and Baseline 
B (week 4) of the 8 week double-blind Phase B.  
Incomplete improvement in depressive symptoms is defined as patients demonstrating a <40% reduction from 
Baseline A on the Children depression rating scale revised version (CDRS-R), and with a (CDRS-R) ≥40 total 
score and confirmed by a Parent Global Assessment – Global Improvement (PGA) value of >2.
A total of 600 patients (depending on the blinded sample size reassessment, see section 18.11) are planned to 
be randomised to Phase B. Randomisation will be done blinded at the end of Phase A (Week 4) using an 
Interactive Voice/Web Response system (IVRS/IWRS).
Patients participating in Phase B will be asked to come back to the study site for a safety follow up 4 weeks 
after early withdrawal or completion. This procedure will not apply for patients entering in an extension 
study. 
Patients randomised to the 10 mg/day vortioxetine group will receive a lower initial dose (5 mg/day for 2 
days) prior to receiving 10 mg/day. Patients randomised to the 20 mg/day vortioxetine group will receive a 
lower initial dose (5 mg/day for 2 days followed by 10 mg/day for 2 days and 15 mg/day for 2 days) prior to 
receiving 20 mg/day. Patients randomised to the fluoxetine 20 mg/day group will receive a lower initial dose 
(10 mg/day for 6 days) prior to receiving 20 mg/day.
Based on tolerability the dose may be reduced at Week 8 (Visit 10 = Week 4 of Phase B). For patients 
randomised to vortioxetine the reduction will be by 5 mg/day and for fluoxetine 10 mg/day. No dose increase 
will be allowed.
Patients who do not fulfil the criteria of incomplete improvement in Phase A at Week 3 will be withdrawn 
from the study before Week 4. Patients who do not fulfil the criteria of incomplete improvement at week 4 
will be withdrawn from the study and not participate in the double-blind Phase B of the study. No specific 
study related follow-up is required for these patients. However as rescue procedure, they may receive up to 4 
outpatient visits to the study site for consultations over a two-month period. 
Patients will receive 5 sessions of standardised brief psychosocial intervention at Week 1,2,3,5 and 8. 
Supportive psycho-educative material will be handed out to patients and families at the Screening Visit.
The study design is presented in Panel 1 and the scheduled assessments are summarised in Panel 2.
Efficacy and safety measures will be assessed at relevant time points during the study summarised in Panel 2.
Target Patient Population

Statistical Methodology
The following analysis sets will be used to analyse and present the data:
all-patients-enrolled (APES) – all patients enrolled to the 4-week single-blind period (Phase A) who 
received at least one dose of IMP 
all-patients-randomised  Phase B (APRS) – all patients randomised to the double-blind, 8-week treatment 
period (Phase B)  
all-patients-treated  set Phase B (APTS) – all patients randomised to the double-blind, 8-week treatment 
period (Phase B) who took at least one dose of double-blind IMP 
full-analysis set Phase B (FAS) – all patients in the APTS who had a valid Baseline B assessment and at 
least one valid post-Baseline B assessment of the CDRS-R total score.
The efficacy analysis will be based on the FAS 
Primary analysis:
For the primary endpoint (change from Baseline B in the CDRS-R total score to Week 8 in phase B (Week 
12)), comparisons of the pooled doses of vortioxetine 10 and 20 mg/day versus placebo will be made using 
Mixed Model Repeated Measurements (MMRM) with freely varying mean and covariance structure and 
with country as a fixed factor and Baseline B CDRS-R score as a covariate interacting with visit. Treatment 
(vortioxetine 10 mg/day, vortioxetine 20 mg/day, fluoxetine, and placebo) is included as a fixed factor 
interacting with visit. For the primary endpoint a contrast test with weights 0.5, 0.5, 0, and -1, respectively, 
to estimate the average effect of the pooled doses of vortioxetine against placebo, based on the LSMeans for 
the treatment by visit interaction at Week 8 in phase B (Week 12). This will be evaluated at a two-sided 5% 
significance level. Subsequently each vortioxetine dose will be tested separately against placebo using a 
two-sided 5% significance level. To adjust for multiplicity a closed testing strategy is applied where 
statistical significance can be claimed on the individual doses only if significance is claimed for the pooled 
vortioxetine doses.1
Sensitivity analyses of the primary endpoint: 
The primary endpoint will also be analysed using an analysis of covariance (ANCOVA, OC and last 
observation carried forward [LOCF]) as sensitivity analysis. The Missing at Random assumption behind the 
MMRM model will be investigated.
Analyses of other efficacy endpoints:
For continuous endpoints, the same methodology as the primary analysis described for the primary endpoint 
will be used. In addition ANCOVA will be performed (OC and LOCF).
For dichotomous endpoints, such as response and remission, logistic regression with treatment as a factor 
and the baseline score as a covariate will be used. This will be done based on OC, LOCF and NRI.
The potential treatment effect on cognitive dysfunction will be separated into a direct effect and an indirect 
effect that is mediated through an improvement in depression. These effects will be estimated using two 
ANCOVA models. In the first model the change from baseline in SDMT (number of correct digits) is the 
dependent variable, while change from baseline CDRS-R total score is included as a covariate and treatment 
as a factor. This model gives an estimate of the direct effect. In the second ANCOVA model change from 
baseline CDRS-R total score is the dependent variable while treatment is a factor. Combining the estimated 
treatment effect in this model with the relation between CDRS-R and SDMT in the first model gives an 
estimate of the indirect effect. Finally, the estimated direct and indirect effects will be expressed as 
proportions of the total effect. The analyses are performed using change from Baseline B after 4 Weeks of 
treatment and after 8 weeks of treatment as endpoint, respectively. Also, both OC and LOCF are 
considered.
The safety analyses will be based on the APES and the APTS.

Statistical Methodology continued
No interim analyses for efficacy are planned. A DMC will monitor safety data at regular intervals to be 
specified in the Data Monitoring Committee Charter. To ensure that the study is sufficiently powered an 
estimate of the variability of the primary endpoint and the withdrawal rate will be obtained. The analysis will 
be performed after at least 75% of the initially planned randomised patients have either completed or 
withdrawn from the study and will be based on blinded and pooled data from all groups. Based on these 
estimates the power calculation will be updated and adequate actions will be taken if the study has lost power.
Since all analyses are done with blinded data, there is no inflation of the Type 1 error rate and no alpha 
adjustment is necessary.
Patient disposition and demographics will be summarised using descriptive statistics.
Pharmacokinetic Analysis
Sparse PK samples (2) will be collected to measure vortioxetine and fluoxetine plasma concentration; however 
the population PK analysis will only be conducted for vortioxetine. Plasma concentrations of fluoxetine will be 
listed. The population PK of vortioxetine will be assessed by means of nonlinear mixed effect modelling and 
the results from the analysis will be reported in a separate population PK report.
Sample Size Considerations
Assuming a standard deviation (SD) of 11 on the treatment comparisons for the primary endpoint and a 
withdrawal rate of 15-20%, then randomising 120 patients per group and applying a closed testing procedure to 
keep the overall significance level at 5% will provide a power of at least 85% for claiming significance of the 
pooled vortioxetine doses if both doses have an effect of 4 points at Week 8 in Phase B (Week 12).
The blinded sample size reassessment will ensure that the power of at least 85% is maintained in the study.

Ethical Rationale for Study and Study Design
In May 2014, WHO's Health for the world’s adolescents report reveals that depression is the predominant cause 
of illness and disability for both boys and girls aged 10 to 19 years and adds that the top 3 causes of adolescent 
deaths globally are road traffic injuries, HIV/AIDS, and suicide. Worldwide, an estimated 1.3 million 
adolescents died in 2012. The prevalence of Major depressive disorder (MDD) is estimated to be approximately 
2% in children and 4% to 8% in adolescents. 
As outlined in the EMA Assessment of the Paediatric Needs in psychiatry there is a therapeutic need in the 
paediatric population of depressed patients. Only one antidepressant, fluoxetine, is currently approved in 
Europe for the treatment of MDD in children and adolescents. In the US only fluoxetine is approved for 
children and fluoxetine and escitalopram for the adolescent population. Development of a new antidepressant 
will increase and strengthen the pharmacological treatment options for this patient population. This study is part 
of the agreed EMA Paediatric Investigational Plan (PIP) for vortioxetine and the US Pediatric Research Equity 
Act (PREA) with the purpose to investigate the anti-depressive effect of vortioxetine in MDD patients aged 12 
to 17 years. It is the expectation that the investigation plan will provide positive efficacy data, with a favourable 
safety and tolerability profile, and therefore demonstrate a positive benefit-risk ratio for the use of vortioxetine 
in the paediatric population.
Vortioxetine is approved in the US, EU and a number of other countries for the treatment of MDD in the adult 
population. The evaluation of the safety and tolerability of vortioxetine is based on data from a large clinical 
development programme in adult and elderly patients. In the overall clinical development programme treatment 
with vortioxetine at the therapeutic doses (5-20 mg/day) was safe and well tolerated. The approved 
recommended dose range of 5-20 mg/day for adults was evaluated in a pharmacokinetic and tolerability study 
performed in the paediatric population (aged 12 to 17 years) designed to guide the choice of doses to be used in 
the planned paediatric investigation plan. Hence the chosen doses of vortioxetine (10 and 20 mg/day) for this 
study is based on the results from the paediatric pharmacokinetic and tolerability study and the knowledge from 
the adult studies. As the sole antidepressant approved both in children and adolescents for MDD in EU and US, 
fluoxetine has been selected as comparator, to provide evidence of assay sensitivity.
The presence of a high placebo response rate is known to be a confounding factor in antidepressant studies, 
particularly in those enrolling children and adolescents. The recent studies of duloxetine in the treatment of 
paediatric patients with Major depressive disorder (MDD) were failed as neither duloxetine nor the active 
control (fluoxetine, with known efficacy in children and adolescents with MDD), were statistically significantly 
different from placebo on the primary outcome measure.  
The present study is designed with the aim to lower the placebo response and includes a single-blind phase 
(Phase A) where patients who respond to standardised brief psychosocial intervention will not be eligible for 
entering the double-blind IMP treatment phase (Phase B). Furthermore patients and parents are blinded to the 
time point of randomisation to the double-blind phase in order to lower expectations. This study will permit the 
investigation of the efficacy and safety of a new potential treatment of MDD in paediatric patients and the 
inclusion of a placebo group has major scientific importance in this evaluation to ensure adequate evaluation of 
efficacy as well as distinguishing disease manifestations from adverse reactions of the compound. The choice of 
the double-blind 8 week study duration is based on previous experience with positive studies and European 
guidelines.

The patients will be asked to attend the investigational clinic at regular intervals to ensure an adequate follow-
up. All visits will be performed on an outpatient basis at the clinic other than the follow-up visit that can be a 
phone call. In order to minimize potential pain, distress, and fear, patients will be seen in facilities which will be 
appropriate for childcare. The study personnel who interact with study participants will be experienced health 
care professionals (physicians with paediatric qualification, qualified paediatric nurses or psychologists) and 
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 venipuncture will be minimized with the use of topical anaesthesia. 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.
The investigator plays an important role in protecting the safety of the patient. The assessment of potential 
burden and risk is defined specifically in the clinical study protocol (safety rating scales, recording of adverse 
events, clinical safety laboratory tests (blood biochemistry, haematology and urine analysis), vital signs (blood 
pressure and pulse rate,), weight, electrocardiogram and physical examination) and these will be evaluated by 
the investigator at each visit to ensure patient’s safety and wellbeing. If it does not remain in the patient’s best 
interest to stay in the study the investigator will ensure that the patient is excluded. If the patient is not 
completing the study, a treatment will be offered to the patient at the discretion of the investigator in line with 
clinical practice. 
In accordance with Good Clinical Practice, qualified medical personnel at H. Lundbeck A/S will be readily 
available to advice on study-related medical questions. Medical monitoring and safety surveillance will be 
performed throughout the study, according to Lundbeck standard procedures and H. Lundbeck A/S will 
regularly monitor and re-examine the balance of risk and benefit of the full clinical study so that the health and 
well-being of paediatric patients enrolled will be safeguarded. 
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 both by rating scale (The Columbia-Suicide Severity Rating Scale) and/or by the investigator’s 
judgement. 
An independent Data Monitoring Committee will be established in order to review the safety and tolerability 
data throughout the study. The same DMC will cover all the clinical studies in the paediatric vortioxetine 
program.

a.
This visit should take place as soon as possible after the patient withdraws from the study. Any visit during 
Phase A, can be converted in to a withdrawal visit on the day of the visit. The BPI is optional if a visit 
during Phase A is converted into a withdrawal visit.
b.
This can be a telephone contact, unless an SAE has occurred since the last visit or 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). All enrolled 
patients should have a safety follow-up visit unless they continue into the extension study.
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 randomisation/baselines. 
d.
The Kiddie-Schedule for Affective Disorders and Schizophrenia for School-aged Children, Present and 
Lifetime version (K-SADS-PL) will be used to confirmed diagnosis of Major depressive disorder (MDD) 
and to assess possible psychiatric co-morbidities.
e.
Must be a blood pregnancy test and should be performed at the Screening Visit and if the patient has 
completed or withdrawn in Phase B according to local requirements for extra pregnancy tests during the 
study.
f.
Should only be performed if the patient has completed or withdrawn in Phase B.
g.
A urine drug screen and a alcohol test are required at the designated time. At any time during the study at 
the discretion of the investigator a drug and/or alcohol screening can be conducted.
h.
The PGA assessment should be in reference to Baseline A. 
i.
One familiarity session for SDMT must be performed at the Screening Visit. This should be documented in 
the medical records. No data are to be entered in the eCRF.
j.
Samples will be collected at the designated time points. Any results of the Translational Medicine 
Assessments will not be available at the time of reporting and will consequently not be part of the actual 
report of the study.       
k.
Pre-treatment adverse events (before IMP intake i.e. before Baseline B) must be recorded on the Adverse 
Event Form in the eCRF. Adverse events from open questioning in addition to all spontaneously reported 
adverse events must be recorded on the Adverse Event Form in the eCRF. If the adverse event is an SAE, 
the Serious Adverse Event Report Form must also be completed. For practical reasons, questioning for 
adverse events could follow vital sign assessments. In addition, the tolerability will also be assessed using

the Paediatric Adverse Event Rating Scale (PAERS). Application of this scale should follow after the open, 
non-leading question for any adverse events.
l.
Only for adverse events ongoing at Completion/Withdrawal and new SAEs.
m.
The vortioxetine dose may be down-titrated with 5 mg/day based on poor tolerability, only one down-
titration is allowed. No up-titration will be allowed. The fluoxetine dose may be down-titrated to 10 mg/day
based on poor tolerability only one down-titration is allowed. No up-titration will be allowed.

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.2,3,4,5 In May 2014, 
WHO's Health for the world’s adolescents6 report reveals that depression is the predominant 
cause of illness and disability for both boys and girls aged 10 to 19 years and adds that the top 
3 causes of adolescent deaths globally are road traffic injuries, HIV/AIDS, and suicide. 
Worldwide, an estimated 1.3 million adolescents died in 2012. The prevalence of Major 
depressive disorder (MDD) is estimated to be approximately 2% in children and 4 to 8% in 
adolescents.4,5,7,8
Only one antidepressant, fluoxetine, is currently approved in Europe for the treatment of 
MDD in children and adolescents. In the US only fluoxetine is approved for children and 
fluoxetine and escitalopram for the adolescent population. Development of a new
antidepressant will increase and strengthen the pharmacological treatment options for this 
patient population.
Signs and symptoms of MDD are similar to the adult population, but depressive disorders 
meeting the diagnostic criteria rarely is present before the age of seven years.9,10 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 than children to 
complain of feelings of hopelessness/helplessness, lack of energy and to have a higher rate of 
suicidal thoughts.11,12 For this reason separate studies are to be conducted in children and 
adolescents.10
The aim of this study is to evaluate the efficacy of vortioxetine 10 mg/day and 20 mg/day 
versus placebo after 8 weeks of treatment on depressive symptoms in children aged 12 to 17
years with a DSM-5™ 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.13
For information on the reference compound fluoxetine please refer to the Summary of Product 
Characteristics (SmPC)/Prescribing Information.

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.14
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
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 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).13
In study 12708A, entitled An open-label study evaluating the pharmacokinetics and 
tolerability of Lu AA21004 in connection with multiple oral dosing of Lu AA21004 in child 
and adolescent patients with a DSM-IV-TRTM diagnosis of depressive or anxiety disorder, 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 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 20mg/day vortioxetine) and the up-
titration scheme employed in this study are appropriate for the paediatric population. 
1.1.3.2
Efficacy
Vortioxetine has been approved in the US, 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.
To date, the efficacy of vortioxetine has not yet been investigated in children with MDD.
1.1.3.3
Safety
The evaluation of the safety and tolerability of vortioxetine is based on data from a large 
clinical development programme. In the completed Phase II to IV short- and long-term studies
in adults, more than 8000 patients with MDD or Generalized Anxiety Disorder (GAD)
received vortioxetine at doses of 1 to 20 mg/day, corresponding to an overall exposure >3200 
patient-years. Overall short- and long-term treatment with vortioxetine at the therapeutic 
doses (5-20 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 adverse events 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, 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. Abrupt discontinuation of vortioxetine 
after short, as well as after long-term treatment was well tolerated. Based on an 8-week 
vortioxetine study, the direct switch from ≥6-week treatment with selective serotonin reuptake 
inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI) to vortioxetine was well 
tolerated.
The tolerability of vortioxetine in multiple oral doses of 5 to 20 mg/day was also evaluated in 
an open label study among children and adolescent patients (aged 7 to 17 years) with a 
DSM-IV-TR™ diagnosis of depressive or anxiety disorder. The purpose of this uncontrolled, 
open-label study was to assess the safety, tolerability, and pharmacokinetics of vortioxetine in 
children and adolescents with depressive or anxiety disorder and to provide supportive 
information for its dose regimen in paediatric efficacy and safety studies. In total 24 children 
and 24 adolescents received vortioxetine. Based on the data from this study, no concerns were 
raised on the safety and tolerability profile of vortioxetine among paediatric patients with 
depression or anxiety. Vortioxetine was safe and well tolerated following 14 days of dosing as 
well as during an initial up-titration period. Overall, the adverse event profile in adolescents 
and children appeared similar to that of the adult population. Nausea and headache were the 
TEAEs with the overall highest incidence in this study,  reported in 11 (Nausea) and 12 
(headache) patients. Nausea is also the most common TEAE in studies with adult patients,

with an incidence of approximately 20 to 30% following 5 to 20 mg vortioxetine. Other 
common TEAEs were sedation, abdominal pain upper, fatigue, and vomiting. There was no 
apparent relationship between dose and the incidence of these adverse events. 
1.2
Rationale for the Study
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.2,3,4,5
As outlined in the EMA Assessment of the Paediatric Needs in psychiatry there is a 
therapeutic need in the paediatric population of depressed patients.15 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 in 
the treatment of children and adolescents with MDD,16,17 and escitalopram in the treatment of 
adolescents with MDD.18,19
Specific studies are necessary in the paediatric population and separate studies should 
generally be conducted in children and adolescents.20 This study is part of the agreed EMA 
Paediatric Investigational Plan (PIP) for vortioxetine and the US Paediatric Research Equity 
Act (PREA) with the purpose to investigate the antidepressive effect of vortioxetine in MDD 
patients aged 12 to 17 years. It is the expectation that the investigation plan will provide 
positive efficacy data, with a favourable safety and tolerability profile, and therefore 
demonstrate a positive benefit-risk ratio for the use of vortioxetine in the paediatric 
population.

Study Design
3.1
Overview of the Study Design
This study has been designed in accordance with the Declaration of Helsinki.21
This is an interventional, multi-national, multi-site, randomised, two- phase, single- and 
double-blind, parallel-group, placebo-controlled, active reference (fluoxetine), fixed-dose 
study.
This study will be conducted in compliance with the protocol, Good Clinical Practice,22 and 
applicable regulatory requirements.
An overview of the study is presented in Panel 1
The study will consist of a screening period of 5-15 days and will consist of two phases
(Phase A and Phase B) after this screening period.
Phase A is a single blind 4-weeks period where patients (and parents) are blinded and receive 
placebo + Brief Psychosocial Intervention (BPI). If not responding to BPI/placebo then 
patients are randomised into Phase B.
Phase B is a double-blind 8-weeks period where patients and investigators are blinded. In this 
phase all patients continue to receive BPI and in addition either placebo, vortioxetine 10 mg, 
vortioxetine 20 mg, or fluoxetine 20 mg.
The patient is a boy or a girl, aged ≥12 and ≤17 at Screening Visit with a diagnosis of MDD
according to DSM-5TM Criteria and a CDRS-R score ≥45 and a CGI-S score ≥4 at the 
Screening Visit and the Baseline A Visit (Week 0).
Approximately 750 patients are planned for enrolment to the 4-week treatment with 
standardised brief psychosocial intervention and single-blind placebo period (Phase A). At the 
end of Phase A (Baseline B) a total of 600 patients (depending on the blinded sample size 
reassessment, see section 18.11) with incomplete improvement are to be randomised to the 8 
week double-blind Phase B in a 1:1:1:1 ratio to vortioxetine 10 mg, vortioxetine 20 mg, 
fluoxetine 20 mg, or placebo. Incomplete improvement in depressive symptoms is defined as 
a <40% reduction from Baseline A on the Children depression rating scale revised version 
(CDRS-R), and with a (CDRS-R) ≥40 total score and confirmed by a Parent Global 
Assessment- Global Improvement (PGA) value of >2.

Patients who do not fulfil the criteria of incomplete improvement in Phase A at Week 3 will 
be withdrawn from the study before Week 4. Patients who do not fulfil the criteria of 
incomplete improvement at week 4 will be withdrawn from the study and not participate in 
the double-blind Phase B of the study. No specific study related follow-up is required for 
these patients. However as rescue procedure, they may receive up to 4 outpatient visits to the 
study site for consultations over a two-month period. 
Patients will receive 5 sessions of standardised brief psychosocial intervention at Week 
1,2,3,5 and 8.
An independent Data Monitoring Committee will be established in order to review the safety 
and tolerability data throughout the study.
An internal safety committee at H. Lundbeck A/S has been set up for vortioxetine, who will 
perform regular evaluations of blinded safety data.
3.2
Rationale for the Study Design
The proposed Study 12710A is a randomised, two-phase single- and double-blind, fixed-dose 
study with the primary objective to evaluate the efficacy of vortioxetine 10 mg/day and 20 
mg/day versus placebo after 8 weeks of treatment on depressive symptoms in adolescents
with a DSM-5™ diagnosis of MDD. Secondary objectives are to evaluate the efficacy of 
vortioxetine 10 mg/day and 20 mg/day versus placebo during the 8 weeks of treatment on 
global clinical impression, functionality, health-related quality of life and to confirm the 
population pharmacokinetics of vortioxetine in paediatric patients, aged 12 to 17 years. In 
addition the efficacy of vortioxetine 10 mg/day and 20 mg/day versus placebo on co-morbid 
symptoms will be explored.
In the overall adult clinical development programme treatment with vortioxetine at the 
therapeutic doses (5-20 mg/day) was safe and well tolerated. It has been suggested that a 
failure to conduct and use information from appropriately designed preliminary 
pharmacokinetic and dose-finding studies has contributed to the failure of several large scale 
antidepressant studies in the paediatric MDD population.23 The chosen doses of vortioxetine 
(10 and 20 mg/day) for this study is based on the knowledge from the clinical development 
programme in adult patients and from the paediatric pharmacokinetic and tolerability study 
performed in the paediatric population (aged 12 to 17 years) designed to guide the choice of 
doses to be used in the planned paediatric investigation plan.
The presence of a high placebo response rate is known to be a confounding factor in 
antidepressant studies, particularly in those enrolling children and adolescents. The recent 
studies of duloxetine in the treatment of paediatric patients with Major depressive disorder
(MDD) were failed as neither duloxetine nor the active control (fluoxetine, with known 
efficacy in children and adolescents with MDD), were statistically significantly different from 
placebo on the primary outcome measure.24,25
The present study is designed with the aim to lower the placebo response and includes a 
single-blind phase (Phase A) where patients who respond to standardised brief psychosocial 

H. Lundbeck A/S 
Confidential
Page 30 of 86
intervention and/or placebo will not be eligible for entering the double-blind IMP treatment 
Phase (Phase B). Furthermore patients and parents are blinded to the time point of 
randomisation to the double-blind phase in order to lower expectations. 
The choice of the double-blind 8 week study duration is based on previous experience with 
positive studies and European guidelines.20 The 4-week single-blind period (Phase A) of 
treatment with standardised brief psychosocial intervention and single-blind (patients and 
parents) placebo run-in phase is in alignment with the new Guideline on clinical investigation 
of medicinal products in the treatment of depression20 and consistent with the NICE treatment 
guideline.26 Studies should include only patients with insufficient response to psychotherapy 
and all subjects should receive psychosocial interventions throughout the trials.20 For this 
reason patients who respond to placebo and or standardised brief psychosocial intervention 
received during the 4-week single blind period will not be included in the 8 week double blind 
treatment period. 
To standardise the psychosocial intervention, a brief psycho social intervention program (BPI) 
is developed for this study The BPI arises from the Specialist Clinical Care (SCC) programme 
and has its origins in the work of the ADAPT27 RCT team in order to implement high quality 
psychosocial intervention in the study. It is a pragmatic synthesis of clinical practice that 
results in good quality specialised psychosocial care for depressed children and adolescents.
A detailed description of key elements of comprehensive BPI case management is provided in 
a manual that will be delivered to the site. 
The primary efficacy endpoint will be the CDRS-R total score, The CDRS-R is the most 
widely used rating scale in clinical trials for assessing severity of depression and change in 
depressive symptoms in children and adolescents with depression. The CDRS-R is based on 
the adult Hamilton Depression Rating Scale. The Psychometric analyses provide evidence 
that the CDRS-R is a valid measure of severity and improvement of depressive symptoms in 
paediatric patients. A score of ≥40 is indicative of depression, whereas a score ≤28 is often 
used to define remission (minimal or no symptoms).
The Parent Global Assessment- Global Improvement (PGA) is used as a secondary efficacy 
measure of the antidepressant effect symptoms and to confirm incomplete improvement in 
depressive symptoms. The PGA has been used receptively and successfully in studies in 
ADHD. The General Behavior Inventory 10-Item Depression Scale28 will also be used to 
assess depressive symptoms. The GBI 10- item version has been shown to discriminate 
between diagnostic groups using youth self-report.28, 29 The CGI-S and CGI-I are used for 
assessing disorder severity and improvement.30
The Children’s Global Assessment Scale (CGAS) and the PedsQL Present Functioning Visual 
Analogue Scales (PedsQL™ VAS) will be used to assess functionality and the Paediatric 
Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q)31 will be used to 
assess health-related quality of life. Children and adolescents with MDD are at high risk of 
having severe difficulties in various domains of functioning and in quality of life.2,32
Both the CGAS, PedsQL™ VAS and PQ-LES-Q are validated scales appropriate for use in 
children and adolescents with psychiatric disorders.32,33

Cognitive dysfunction is well recognised in Adult MDD but available neuropsychological 
data on the cognitive performance of children and adolescents with MDD yields mixed 
results,34 and it is not known if parameters like age, depression severity or an antidepressant 
treatment are correlated to the cognitive impairments of children and adolescents with MDD. 
The Symbol Digit Modalities Test (SDMT),35 is an objective measure of cognitive 
dysfunction that integrates elements of attention, speed of processing and executive function 
including working memory. The SDMT was developed to identify individuals with 
neurological impairment and measures the time to pair abstract symbols with specific 
numbers. It is an inverse form of the Digit Symbol Substitution Test (DSST)36 prompting for 
numbers instead of symbols. The SDMT has a high sensitivity to cognitive impairment in 
neuropsychiatric disorders, is sensitive to change, there are paediatric norms and it has been 
used in the paediatric population.37,38 In addition the SDMT correlates well with the DSST 
(0.80 for normal subjects) which has shown sensitivity to treatment induced change of 
cognitive function in the adult population of patients with MDD.

Ethics
4.1
Ethical Rationale
Patients 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 the US, EU and a number of other countries for the treatment of MDD in the 
adult population. The evaluation of the safety and tolerability of vortioxetine is based on data 
from a large clinical development programme in adult and elderly patients. In the overall 
clinical development programme treatment with vortioxetine at the therapeutic doses 
(5-20 mg/day) was safe and well tolerated. The approved recommended dose range of 
5-20 mg/day for adults was evaluated in a pharmacokinetic and tolerability study performed 
in the paediatric population (aged 12 to 17 years) designed to guide the choice of doses to be 
used in the planned paediatric investigation plan. Hence the chosen doses of vortioxetine (10 
and 20 mg/day) for this study is based on the results from the paediatric pharmacokinetic and 
tolerability study and the knowledge from the adult studies. As the sole antidepressant 
approved both in children and adolescents for MDD in EU and US, fluoxetine has been 
selected as comparator, to provide evidence of assay sensitivity.
This study will permit the investigation of the efficacy and safety of a new potential treatment 
of MDD in paediatric patients and the inclusion of a placebo group has major scientific 
importance in this evaluation to ensure adequate evaluation of efficacy as well as 
distinguishing disease manifestations from adverse reactions of the compound. The patients 
will be asked to attend the investigational clinic at regular intervals to ensure an adequate

follow-up. All visits will be performed on an outpatient basis at the clinic, other than the 
follow-up visit that can be a phone call. In order to minimize potential pain, distress, and fear, 
patients will be seen in facilities which will be appropriate for childcare. The study personnel 
who interact with the patients will be experienced health care professionals (physicians with 
paediatric qualification, qualified paediatric nurses or psychologists) and 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 venipuncture will be minimized with the use of 
topical anaesthesia. 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.
The investigator plays an important role in protecting the safety of the patient. The assessment 
of potential burden and risk is defined specifically in the clinical study protocol (safety rating 
scales, recording of adverse events, clinical safety laboratory tests (blood biochemistry, 
haematology and urine analysis), vital signs (blood pressure and pulse rate), weight, 
electrocardiogram and physical examination) and these will be evaluated by the investigator 
at each visit to ensure the patient’s safety and wellbeing. If it does not remain in the patient’s 
best interest to stay in the study the investigator will ensure that the patient is excluded. If the 
patient is not completing the study, a treatment will be offered to the patient at the discretion 
of the investigator in line with clinical practice. 
In accordance with Good Clinical Practice,22 qualified medical personnel at Lundbeck or a 
delegate specify will be readily available to advise on study-related medical questions. 
Medical monitoring will be performed throughout the study. Safety data will be reviewed 
regularly by the Lundbeck Vortioxetine Safety Committee to ensure that prompt action is 
taken, if needed, to maximise patient safety.
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 both by rating scale The Columbia-Suicide 
Severity Rating Scale and/or by the investigator’s judgement. 
An independent Data Monitoring Committee will be established in order to review the safety 
and tolerability data throughout the study. The same DMC will cover all the clinical studies in 
the paediatric vortioxetine program.
In accordance with Good Clinical Practice,22 the investigator will be responsible for all study-
related medical decisions.
4.2
Informed Assent/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 parents/legal representative.

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 legal representative(s) (typically their parent[s]) to assume 
responsibility for their participation in clinical studies.39
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 legal representatives the aims, methods, and potential hazards of the 
study and any discomfort it may entail. The patients and their legal representatives 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. The patients and their legal 
representatives must be informed of the possibility of withdrawing assent/consent 
(section 8.5).
The patients and their legal representatives 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 legal representatives. Prior to including a 
patient in the study, an Informed Assent Form must be signed and dated by the patient and an 
Informed Consent Form must be signed by his or her legal representative and signed and 
dated by the investigator or a designee. The patients and their legal representatives must
receive a copy of the written information (Patient Information Sheet) as well as a copy of the 
signed Informed Assent/Consent Forms.
The consent procedures described above will only be implemented if allowed by local law 
and regulations and will only be initiated after approval by the relevant ethics committees.
The blood samples for exploratory biomarker analysis may be shared with academic or public 
institutions and companies; however, Lundbeck will retain full control of the samples and 
their use in accordance with the information in the Patient Information Sheet and a material 
transfer agreement.

Personal Data Protection
The data collected in the study will be processed in accordance with the specifications 
outlined in European Union legislation40 to ensure that requirements regarding personal data 
protection are met. If an external organisation will process data on behalf of Lundbeck, a 
contractual procedure will be signed between Lundbeck and the external organisation to 
ensure compliance with the above-mentioned legislation.
4.4
Independent Ethics Committees (IECs) and Institutional Review Boards (IRBs)
This study will be conducted only after approval of the protocol has been granted by the 
appropriate IEC or IRB and a copy of the written approval has been received by Lundbeck.
The investigator must not screen any patients before receiving written approval from the IEC 
or IRB.
The IEC or IRB must be informed when specific types of protocol amendments have been 
made and must be asked whether a re-evaluation of the ethical aspects of the study is 
necessary.
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.

conduct or interpretation of the study.
28. The patient is, in the investigator’s opinion, unlikely to comply with the protocol or is 
unsuitable for any reason.
29. The patient has attempted suicide within the last 12 months or is at significant risk of 
suicide (either in the opinion of the Investigator or defined as a “yes” to suicidal ideation 
questions 4 or 5 or answering “yes” to suicidal behaviour on the C-SSRS within the last  
12 months).

postponed until a repeat ECG is taken, if it is taken within 24 hours
• the patient is lost to follow-up (defined as a patient who fails to comply with scheduled 
study visits or contact, who has not actively withdrawn from the study, and for whom no 
alternative contact information is available [this implies that at least two attempts have 
been made to contact the patient])
• the patient and his or her parent(s)/legal representative (s) fails to comply with study 
procedures
• the patient attempts suicide or is at significant risk of suicide (either in the opinion of the

6.1
Treatment Regimen
The screening period will be 5 to 15 days followed by a 4-week single-blind period (Phase A) 
of treatment with standardised brief psychosocial intervention and placebo. Patients who 
demonstrate an incomplete improvement of depressive symptoms at the end of Week 4 will 
be randomised to a double-blind, 8-week treatment period (Phase B) in a 1:1:1:1 ratio to 
vortioxetine 10 mg/day, vortioxetine 20 mg/day, fluoxetine 20 mg/day, or placebo.
Patients randomised to the 10 mg/day vortioxetine group will receive a lower initial dose 
(5 mg/day for 2 days) prior to receiving 10 mg/day. Patients randomised to the 20 mg/day 
vortioxetine group will receive a lower initial dose (5 mg/day for 2 days followed by 
10 mg/day for 2 days and 15 mg/day for 2 days) prior to receiving 20 mg/day. Patients 
randomised to the fluoxetine 20 mg/day group will receive a lower initial dose (10 mg/day for 
6 days) prior to receiving 20 mg/day.
Based on tolerability the dose may be reduced at Week 8 (Visit 10 = week 4 of Phase B). For 
patients randomised to vortioxetine the reduction will be by 5 mg/day and for fluoxetine 10
mg/day. No dose increase will be allowed.
The dose titration schedules are presented in Panel 3.
The capsule should be taken orally, once daily, preferably in the morning.

IMPs, Formulations, and Strengths
The IMPs supplied by Lundbeck in this study are:
• Vortioxetine – 5 mg, 10 mg, 15 mg and 20 mg encapsulated tablets
• Fluoxetine – 10 mg and 20 mg encapsulated tablets or encapsulated capsules
• Placebo – encapsulated tablets
The IMPs will be identical in appearance.
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.
The IMP will be provided in 1-week wallet cards, containing 10 capsules.
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 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 the Department of Clinical Supply, H. Lundbeck A/S, and, where necessary, new 
QP releases are made.
The IMPs will be identified using a unique IMP 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
The patients will be assigned a screening number by the eCRF system, and that number will 
be used to identify them throughout the study.
An Interactive Voice/Web Response System (IVRS/IWRS) will be used in this study. When a 
patient is to be randomised, the investigator will contact the IVRS/IWRS. The IVRS/IWRS
will allocate the patient to a treatment group during the call and assign the patient a 
randomisation number in accordance with the specifications from the Department of 
Biostatistics, H. Lundbeck A/S, and then follow up by fax, e-mail, or the web (depending on 
availability or preference at the site).
6.5
IMP Accountability
The IMP(s) must be tracked at each site using two logs:
• a site-specific log to track the complete inventory (that is, what is shipped between the site 
and Lundbeck)
• a patient-specific log to track what is dispensed to and returned by the patient
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 IMP(s). This record must be available 
for inspection at any time.
6.6
Unblinding Procedures
GPV, and the investigator or the pharmacist (if applicable) will have access to the details of 
the double-blind treatment for each patient. Access to these details will be via IVRS/IWRS.
The IVRS/IWRS unblinding procedure is described in the IVRS User Guide.
The investigator may only break the code if knowledge of the IMP is necessary to provide 
optimal treatment to the patient in an emergency situation. If possible, the investigator must 
consult the CRA before breaking the code. The investigator must record the date, time, and 
reason for breaking the code on the Completion/Withdrawal Form (this corresponds to the
Completion/Withdrawal Visit, as the patient must be immediately withdrawn from the study) 
and sign the form. If the emergency situation was an adverse event, it must be recorded on an 
Adverse Event Form. The CRA must be notified immediately. 
The IVRS/IWRS will also 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 e-mail, depending on 
availability/preference.

6.7
Post-study Access to IMP
After completion of the study or withdrawal from the study, the patient must be treated in 
accordance with normal practice.
No IMP will be provided by Lundbeck.
7
Concomitant Medication
Concomitant medication is any medication other than the IMPs that are taken during the 
study, including the Screening Period.
The concomitant medications that are disallowed or allowed with restrictions during the study 
are summarised 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 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 dose has changed 
due to a new disorder or worsening of a concurrent disorder, the disorder must be recorded as 
an adverse event.
Concomitant medication initiated after the last dose of IMP must only be recorded if 
associated with an 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. Further details are in chapter 9.
After completing or withdrawing from the study, the patient must be treated in accordance 
with usual clinical practice. However, this will not apply for patients entering in an extension 
study. 
8.2
Screening Visit (Visit 1)
Screening Visit takes place between Day –5 and Day –15 prior to Baseline A. 
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 at Lundbeck, provided the 
Medical Monitor accepts the rationale provided for the extension.

H. Lundbeck A/S 
Confidential
Page 43 of 86
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 begin before any screening assessment is done and must comply with the 
required washout periods in Appendix II. Screening assessment is described in Panel 2.
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-Randomisation 
Form needs to be completed by the site and transmitted to the Contract Research Organisation 
(CRO) for their review. A confirmation that the patient can continue further with the study 
procedures is required before randomization.
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.
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 patients with a complete Screening Visit and who fail to 
attend the Baseline A 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.
Authorisation for re-screening may only be granted by the sponsor’s medical expert/CRO 
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 legal representative (if applicable) 
and 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 authorised by the sponsor’s medical expert or state who
• 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
Phase A (Visit 2 to 5)
Phase A starts with Baseline A (Week 0) for the 4 week single-blind phase.
Patients eligible for entering phase A will receive BPI at Week 1, 2 and 3 (visit 3, 4 and 5) 
and placebo. Patients who do not fulfil the criteria of incomplete improvement in Phase A at 
Week 3 will be withdrawn from the study before Week 4. Patients who do not fulfil the 
criteria of incomplete improvement at week 4 will be withdrawn from the study and not 
participate in the double-blind Phase B of the study. No specific study related follow-up is 
required for these patients. However, as rescue procedure, they may benefit from up to four 
outpatient visits to the study site for consultations over a two-month period.
8.4
Phase B (Visit 6 to 12)
Phase B starts with Baseline B (Week 4) for the 8 week double-blind phase.
The patients eligible for Phase B will be randomised at visit 6 (week 4) to one of the four 
treatment arms and receive BPI at Visit 7 and 10.
8.5
Withdrawal Visit (Visit 12)
Patients who withdraw from the study prior to the Completion Visit will be asked to attend a 
Withdrawal Visit, if at all possible. The visit must be scheduled as soon as possible after 
withdrawal.
No new information will be collected from patients who withdraw, except information 
collected in relation to the scheduled Withdrawal Visit or needed for the follow-up of adverse 
events (section 11.5).
The reason for withdrawal must be recorded on the Reason for Withdrawal Form.
For a patient and/or his or her legal representative who withdraw assent/consent:
• if the patient and/or his or her legal representative withdraw assent/consent during a visit 
and then agrees 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 this visit will be used
• if the patient and/or his or her legal representative withdraw assent/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 this 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 record

H. Lundbeck A/S 
Confidential
Page 45 of 86
• if the patient and/or his or her legal representative explicitly request that his or her data 
collected from the time of withdrawal of assent/consent onwards not be used, this will be 
respected
8.6
Safety Follow-up Visit/Contact (Visit 13)
The safety follow-up is conducted to capture serious adverse events (SAEs) that occur during 
the Safety Follow-up Period as well as to follow up on the outcome of adverse events on-
going at the end of the Treatment Period. The safety follow-up may either be conducted as a 
visit to the site or as a telephone contact. The safety follow-up must be conducted 
approximately 30 days after the last dose of IMP.
If any new SAEs have occurred since the last assessment at which the patient received IMP, 
the safety follow-up must, when possible, be a visit to the site.
For adverse events that were on-going 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 on-going at the safety follow-up, the stop date must be recorded as “on-going”. 
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 or 
Withdrawal Visit and judged clinically significant must be followed according to accepted 
medical standards for up to 30 days or until the value normalises or stabilises 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 5.4) should be 
followed until the values normalise or stabilise or a diagnosis or a reasonable explanation has 
been established (see section 11.5).
The safety follow-up for patients who withdraw assent/consent must be performed, if at all 
possible; any information collected will 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 on-going in the study.

Brief Psychological intervention (BPI) 
The patients will receive treatment with standardised brief psychosocial intervention during 
the study. The treatment will be spread across 5 sessions. There will be 3 sessions in Phase A 
(Weeks 1, 2 and 3), followed by 2 sessions in Phase B (Weeks 5 and 8). BPI for depression41
is a comprehensive package of specialist care for children and adolescents with depression. It 
arises from the practise and formulation of a Specialist Clinical Care (SCC) programme and 
has its origins in the work of the ADAPT RCT27 team. It comprises: assessment, formulation, 
case management, achieving engagement with the young person and their parents, planning 
and delivery of treatment. It is structured around core clinical skills, key elements known to 
counter depressive tendencies, psycho-education & liaison and multi-systemic formulation 
(biological, psychological and social elements). A detailed description of key elements of BPI 
case management is provided in a manual that will be delivered to the site. The manual is 
intended as a guide to practice, not a session-by-session prescription. It is expected across the 
treatment period that due consideration is given to all elements described in the manual. The 
clinician is directed to use their clinical discretion to decide in which session to apply which 
element of BPI. Session length for BPI will be up to 30 minutes. 
10 Assessments
Timing and frequency of all assessments are specified in Panel 2. 
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.

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.
Detailed instruction on how to administer the scales and how to score using the scales will be 
provided to the site in a Rater Guideline.
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.
10.1.3
The Kiddie-Schedule for Affective Disorders and Schizophrenia for School-aged 
Children, Present and Lifetime version (K-SADS-PL). 
The K-SADS-PL42 is a semi-structured diagnostic interview designed to assess current and 
past episodes of psychopathology in children and adolescents. The K-SADS-PL is 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). 
10.1.4
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 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 
authorised 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.

10.1.5
Drug and Alcohol Screening
A urine drug screen and a blood alcohol test are required at the designated time. At any time 
during the study at the discretion of the investigator a drug and/or alcohol screening can be 
conducted. Patients whose urine drug screen is positive for cocaine or other illicit drugs must 
be withdrawn from the study. However, if a patient tests positive for opiates due to incidental 
use of codeine-containing medication, as assessed in a clinical interview, the drug screen may 
be repeated up to three weeks later, but the retest result must be available from a central 
laboratory latest at Visit 2 and has to be negative for this patient to be eligible for enrolment. 
If a patient tests positive for amphetamines due to his/her ADHD current treatment, as 
confirmed by a clinical interview, the patient is eligible for enrolment. If patients have a 
positive blood alcohol result at screening they may continue in the study but only after 
consultation and approval by the medical monitor. Urine drug and blood alcohol screening 
kits will be supplied by a central laboratory.

Clinician rated Scales
10.2.1.1
Use of Clinician-rated Scales
The following assessment tools will be used:
• CDRS-R – assessing depressive symptoms
• CGI – assessing global impression
• CGAS - assessing functionality
Detailed instructions on how to administer the scales and how to score using the scales will be 
provided to the site in a Rater Guideline.
The CDRS-R and CGAS 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.
10.2.1.2
Children depression rating scale revised version (CDRS-R) 
The CDRS-R43 is a clinician-rated scale to measure the severity of depression of children and 
adolescents. The CDRS-R consists of 17 items: 14 items rate verbal observations, and three 
items rate nonverbal observations (tempo of language, hypoactivity, and nonverbal expression 
of depressed affect). Depression symptoms are rated on a 5-point scale from 1 to 5 for the 
verbal observations, and a 7-point scale from 1 to 7 for the nonverbal observations. 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.

10.2.1.3
Clinical Global Impression scales (CGI-S/I)
The CGI30 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 Baseline A 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.
10.2.1.4
Children’s Global Assessment Scale (CGAS) 
The CGAS44 is a clinician-rated global scale to measure the lowest level of functioning for a 
child (4 to 16 years) during a specified time period. The CGAS contains behaviourally-
oriented descriptors at each anchor point that depict behaviours and life situations applicable 
to a child. The items range in value from 1 (most functionally impaired child) to 100 (the 
healthiest). A total score above 70 indicates normal function. The CGAS can be administered 
by a clinician after a training session. It takes approximately 2 minutes to administer CGAS.
10.2.1.5
CDRS-R, CGI, CGAS Rater Qualification and Certification
The CDRS-R, CGI and CGAS 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 should be administered by the investigator responsible for the patient. The 
investigator must be psychiatrists or DO specialised in child and adolescent psychiatry who 
has adequate experience with paediatric patients with MDD. 
Any exceptions must be discussed and approved by Lundbeck.

Use of Neuropsychological Test
The following Neuropsychological test will be used:

SDMT – assessing cognitive performance
Detailed instructions on how to administer the test and how to score the test will be provided

The SDMT will be administered in the local language. During the study, the 
neuropsychological test is to be performed preferably at the same time of the day for an 
individual patient.
One familiarity session for SDMT must be performed at the Screening Visit
10.2.2.1.1
The Symbol Digit Modalities Test (SDMT)
The Symbol Digit Modalities Test (SDMT)45  is a cognitive test designed to assess speed of 
performance requiring visual perception, spatial decision-making and psychomotor skills. The 
SDMT consists of 110 geometric symbols that the patient has to substitute with a 
corresponding digit in a 90-second period. Each correct digit is counted, and the total score 
ranges from 0 (less than normal functioning) to 110 (greater than normal functioning). The
written version of the test will be used in this study. It takes approximately 5 minutes to 
complete and score the SDMT.
10.2.2.1.2
SDMT Rater Qualification and Certification
The SDMT should only be administered by a rater who has adequate experience with 
paediatric patients with MDD and who has adequate experience in administering

Patient and/or Parent Reported Outcomes (PROs)
10.2.3.1
Use of PROs
The following PROs will be used:

GBI – assessing depressive symptoms

PGA – assessing depressive symptoms 

PedsQL VAS – assessing functionality

PQ-LES-Q – assessing health-related quality of life
The GBI, PGA, PedsQL VAS and PQ-LES-Q 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.
10.2.3.1.1
General Behavior Inventory (GBI) 10-Item Depression Scale
The GBI 10-item depression scale46 is a parent- and subject-rated scale designed to screen for 
depressive symptoms in children and adolescents. The ten depression 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 depression scale.
10.2.3.1.2
Parent Global Assessment – Global Improvement (PGA)
The PGA47 is a parent-rated variation of the CGI-I to evaluate the severity of the child’s 
symptoms. The PGA reflects assessments of change from Baseline A symptoms using a 7 
point scale ranging from 1 (very much improved) to 7 (very much worse). It takes 1 to 2 
minutes to score the PGA.
10.2.3.1.3
The PedsQL Present Functioning Visual Analogue Scales (PedsQL™ VAS)
The PedsQL™ VAS48 is designed to measure at-that-moment functioning in children and 
adolescents. The PedsQL VAS consists of 6 domains: anxiety, sadness, anger, worry, fatigue 
and pain using visual analogue scales. The functionality for each domain is measured on a 10

cm line with a happy face at one end and a sad face at the other. The patients are asked to 
mark on the line how they feel. The total score is the average of all 6 items, and the emotional 
distress summary score is the mean of the anxiety, sadness, anger, and worry items. It takes 2 
to 5 minutes to administer and rate the PedsQL VAS.
10.2.3.1.4
Paediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-
LES-Q)
The PQ-LES-Q49 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-
14 assess the degree of satisfaction experienced by subjects 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 1-14 is 14 to 70, with higher scores indicating greater satisfaction. It takes 5 to 
10 minutes to complete the scale.
10.3
Blood Sampling for Vortioxetine and Fluoxetine Quantification
Blood samples (2 x 1 mL) for IMP analysis will be collected in EDTA tubes, simultaneously 
with clinical safety lab samples. The blood sampling and handling procedures are described in 
the study-specific Laboratory Specification Manual.
The blood samples will be analysed for vortioxetine and fluoxetine using methods validated 
in accordance with the EMA Guideline on Bioanalytical Method Validation50 and the FDA 
Guidance for Industry.51 A bioanalytical protocol will be prepared by Lundbeck before the 
plasma samples are analysed.
Selected samples will be subjected to incurred sample re-analysis (ISR) for fluoxetine as part 
of the in-study method validation of the applied bioanalytical method. PK results and ISR 
results will be clearly distinguished from each other in the bioanalytical study report that will
be prepared by the Department of Bioanalysis, H. Lundbeck A/S.
10.4
Safety Assessments
10.4.1
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. Adverse 
events (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 the adverse event 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 adverse events if considered by the investigator to be clinically significant.

Blood samples for the clinical safety laboratory tests will be collected as outlined in Panel 2
of the Clinical Study Synopsis. The blood sampling and handling procedures are described in 
the study-specific Laboratory Specification Manual.
The blood and urine drug screen samples will be analysed at the central laboratory.
The additional urine samples will be collected and analysed at the site using dipsticks. If the 
dipstick evaluation is positive or abnormal, further analysis will be performed at the central 
laboratory.
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 stabilised or until the value has 
returned to a clinically acceptable value (regardless of relationship to IMP). Any value that is 
out-of-range at the Completion or Withdrawal Visit and judged clinically significant must be 
followed according to accepted medical standards for up to 30 days or until the value 
normalises or stabilises 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 record.
Clinically significant out-of-range values must be recorded as an adverse event on an Adverse 
Event Form.
The central laboratory will be notified by the sponsor when the biological samples may be 
destroyed.
10.4.3
Vital Signs
Blood pressure and pulse rate will be measured using a standard digital meter after the patient 
has rested for at least 5 minutes in a supine position. Pulse rate will be recorded before each 
blood pressure measurement.
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.
Vital signs should be assessed prior to blood sampling.
Abnormalities of clinical significance must be recorded as an adverse event on an Adverse 
Event Report Form.

10.4.4
Height and Weight
Height will be measured with a stadiometer, without shoes.
Patients will be weighed wearing light clothing and no shoes. A similar amount of clothing 
must be worn on each occasion.
Abnormalities of clinical significance must be recorded as an adverse event on an Adverse 
Event Form.
10.4.5
Electrocardiograms (ECGs)
A standard 12-lead electronic ECG (eECG) will be performed using digital ECG recording 
equipment provided to the investigator or, upon agreement, to an external cardiology centre.  
The eECGs will be transferred digitally to a central ECG laboratory for evaluation, and the 
results from the central ECG laboratory will include the RR, PR, QRS, QT, and QTc 
intervals.
The investigator will, during the study be provided with the results and a cardiological 
interpretation of the ECG performed by a paediatric cardiologist from the central ECG 
laboratory.
The investigator has the final decision on the clinical significance of the ECG evaluation.
Abnormalities of clinical significance must be recorded as an adverse event on the Adverse 
Event Report Form.
10.4.6
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.
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. The examination at the Screening Visit will be considered the 
baseline physical examination.
The neurological examination must be performed by a physician.
Abnormalities of clinical significance must be recorded as an adverse event on an Adverse 
Event Report Form.
10.4.7
Tanner evaluating
Tanner staging is a scale for assessing physical development and sexual maturity during onset 
and progress of puberty.

H. Lundbeck A/S 
Confidential
Page 56 of 86
The scale includes five 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 at Screening Visit.
10.4.8
Assessment Tools
The Paediatric Adverse Event Rating Scale (PAERS), The Columbia-Suicide Severity Rating 
Scale (C-SSRS) and GBI mania, will be used for evaluation of tolerability and safety.
The PAERS, C-SSRS, and GBI will be administered in the local language. Only the scales 
provided for this Lundbeck study should be used.
Detailed instructions on how to administer the scales and how to score using the scales will be 
provided to the sites in a Rater Guideline.
10.4.9
Paediatric Adverse Event Rating Scale (PAERS)
The PAERS52 is a clinician-rated scale designed and validated to assess adverse events 
occurring in paediatric patients who are treated with psychotropic medication in clinical 
studies.  
The PAERS consists of 45 items: 43 specific signs and symptoms and two to be specified. 
Each item specifies if the adverse event was present recently, if it was resolved (No, Yes), 
related to drug (No, Study drug, Other drug, Drug-drug interaction), its severity (Mild, 
Moderate, Severe, Extreme) and if it impaired function (No, Yes).
The PAERS can be administered by a clinician after a short training session. It takes 
approximately 10 minutes to administer and score the PAERS.
The PAERS must be applied after the non-leading, open questions on any adverse events (see 
section 10.4). As this recording of adverse events should precede the use of the PAERS, the 
numbers of adverse events captured by these two methods potentially differ.
10.4.10 Columbia-Suicide Severity Rating Scale (C-SSRS)
The C-SSRS53 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. 
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.
10.4.11 General Behavior Inventory (GBI) 10-Item Mania Scale
The GBI 10-item mania scale54 is a parent- and subject-rated scale designed to screen for 
manic symptoms in children and adolescents. The 10 items are rated on a scale from 0 (never 
or hardly ever) to 3 (very often or almost constantly). The total score ranges from 0 to 30 
points, with high scores indicating greater pathology. It takes approximately 5 minutes to 
complete the GBI 10-item mania scale.
10.4.12 Rater Qualification and Certification
PAERS and 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 in a study-specific Rater Certification Programme will be 
authorised 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 
process.

Exploratory Assessments
10.5.1
Multidimensional Anxiety Scale for Children short version (MASC-10)
The MASC-1055 is designed to screen for anxiety in children, and is based on the 39-item 
MASC. The MASC-10 consists of 10 items assessing physiological symptoms, social anxiety, 
harm avoidance, and separation/panic. The anxiety symptoms are rated on a 4-point scale 
from 0 (never true about me) to 3 (often true about me). Total score ranges from 0 to 30, with 
higher scores indicating higher levels of anxiety. The MASC-10 takes approximately 5 
minutes to administer and score.

Exploratory Biomarker Assessments
10.6.1
General Considerations
Although the possible future exploratory biomarker analyses will help to increase our 
understanding of the aetiology of MDD and the molecular basis of the drug response, the 
efforts described in this protocol are strictly research based. Therefore, as the complex 
interactions between genes and disease are currently not characterised to a level that translates 
to a meaningful clinical advantage, individual results from the exploratory biomarker analyses 
will not be given to the patients. For the same reasons, individual results will not be added to 
the patients’ medical records.
The patients will have no direct benefit from the exploratory biomarker analyses.
As blood sampling for the exploratory genomics, proteomics, and metabolomics is an integral
part of the study, the main Patient Information Sheet covers these analyses. Conversely, blood 
sampling for the possible future genetic biomarker analysis is optional and a separate Patient 
Information Sheet covers this analysis.
The blood samples for possible future exploratory biomarker analysis, or the data derived 
from these blood samples, may be shared with academic and public institutions and other 
companies. However, Lundbeck will retain full control of the samples and their use in 
accordance with the information in the Patient Information Sheet and a Material Transfer 
Agreement. Furthermore, the results based on the analysis of the samples may be pooled 
across studies to increase the statistical power of the analyses.
A patient and/or his or her legal representative (if applicable) may, at any time and without 
stating a reason, specifically request the destruction of the patient’s exploratory biomarker 
sample, irrespective of his or her continued participation in the study. The investigator must 
send a written request on behalf of the patient to the international study manager. The 
investigator will receive written confirmation from Lundbeck when the sample has been 
destroyed.
The blood samples for genomics, proteomics, and metabolomics will be single-coded using 
the patient’s screening number. The blood samples for genetic biomarker analysis will be 
double-coded as described in EMA’s position paper on pharmacogenetic terminology56 to 
ensure patient privacy protection.
10.6.2
Blood Sampling for Gene Expression Profiling
Blood samples for gene expression profiling will be collected in 2.5 mL PaxGene RNA tubes.
The maximum volume of blood to be collected during the study for this purpose will be 
7.5 mL.

H. Lundbeck A/S 
Confidential
Page 59 of 86
The samples for gene expression profiling will be shipped to a Central Laboratory for sample 
storage.  Sample preparation and analysis may be performed by a Contract Research 
Organisation (CRO) or by a bona fide research collaborator.
10.6.3
Blood Sampling for Metabolomic/Proteomic Biomarkers
Blood samples for metabolomic/proteomic biomarkers will be collected in 2 mL K2 EDTA 
tubes.
The maximum volume of blood to be collected during the study for this purpose will be 6 mL.
The samples for metabolomic/proteomic biomarkers will be shipped to a Central Laboratory
in the United States for sample storage. The analysis may be performed by a Contract 
Research Organisation (CRO) or by a bona fide research collaborator.
10.6.4
Blood Sampling for Pharmacogenetics
It is optional for the patient to donate a blood sample for exploratory pharmacogenetic 
analysis.
A blood sample (2 mL) will be collected in K3 EDTA tube for subsequent DNA extraction.
Blood tubes will be shipped on dry ice to the central laboratory, where DNA will be extracted 
and retained. DNA aliquots will be shipped to a Central Laboratory for storage. 
The genetic variants to be analysed may include single nucleotide polymorphisms (SNPs) and 
copy number variations (CNVs). The analytical methods may be polymerase chain reaction 
(PCR), qPCR (quantitative PCR), sequencing, or whole genome scans on microarrays. The 
analysis may be performed by a Contract Research Organisation (CRO) or by a bona fide 
research collaborator.
10.7
Order of Assessments
The scales should preferably be administered in the following order:
Screening Visit:
• K-SADS-PL
• CDRS-R
• GBI
• PAERS
• C-SSRS
• CGI-S
At visits other than the Screening Visit:
• CDRS-R

• PGA
• CGAS
• SDMT
• PedsQL VAS, PQ-LES-Q, MASC-10
• GBI
• PAERS
• C-SSRS
• CGI-S, CGI-I
The PAERS must be applied after the non-leading, open questions on any adverse events.
10.8
Total Volume of Blood Drawn and Destruction of Biological Material
The total volume of blood drawn from each patient will be approximately 47.5 mL during the 
study.
Additional blood samples may be required if the original blood samples are not viable or if re-
testing is required.
All biological samples will be retained at the bioanalytical facility until the results have been 
reported. The samples will subsequently be destroyed by the responsible analytical laboratory. 
The bioanalytical lab will retain the samples until the bioanalytical report is final and no 
longer than 1 year from LPLV. The ISM/CRS will be notified that the samples are to be 
destroyed, and the documentation for sample destruction will be kept in the bioanalytical 
study file.
The blood samples and any derived material for possible future exploratory pharmacogenetic 
analyses will be destroyed ≤15 years after the end of the study (see definition in section 8.7) 
by a Central Laboratory.
The blood samples and any derived material for possible future exploratory gene expression 
profiling and metabolic or proteomic biomarker assessments will be destroyed ≤10 years after 
the end of the study (see definition in section 8.7) by a Central Laboratory.
10.9
Treatment Compliance
It is the responsibility of the investigator to account for all IMP (ref 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 and fluoxetine will indicate 
whether patient has been overall compliant throughout the study.

11 Adverse Events
11.1
Definitions
11.1.1
Adverse Event Definitions57
Adverse event – is any untoward medical occurrence in a 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 Informed Assent Form and prior 
to the first dose of IMP.
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 hospitalisation or prolongation of existing hospitalisation
• 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 hospitalisation, but may jeopardise 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 hospitalisation; or development of drug 
dependency or drug abuse.
Planned hospitalisations or surgical interventions for a condition that existed before the 
patient signed the Informed Assent Form and that did not change in intensity are not SAEs. 
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).
The C-SSRS has 5 questions addressing suicidal ideation. If level 4 or 5 has been answered 
“yes”, a corresponding SAE should be reported.
Non-serious adverse event – is any adverse event that does not meet the definition of an SAE.

H. Lundbeck A/S 
Confidential
Page 62 of 86
If there is any doubt as to whether an adverse event meets the definition of an SAE, a 
conservative viewpoint must be taken, and the adverse event must be reported as an SAE.
Suspected unexpected serious adverse reaction (SUSAR) – is any adverse event that is 
assessed as serious, unexpected (its nature or intensity is not consistent with the current 
version of the Investigator’s Brochure for vortioxetine13 or the Summary of Product 
Characteristics (SmPC)/Prescribing Information for Fluoxetine), and related to an 
investigational product by either the investigator or the sponsor.
Overdose – is a dose taken by a patient that exceeds the dose prescribed to that patient. Any 
overdose (and associated symptoms) must, at a minimum, be recorded as a non-serious 
adverse event.
11.1.2
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.
• 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 his 
or her normal activities.
Assessment of Causality
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 illness 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.
For pre-treatment adverse events, a causality assessment is not relevant.

H. Lundbeck A/S 
Confidential
Page 63 of 86
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
11.2
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 considered an SAE. If, however, the pregnancy is 
associated with an SAE, the appropriate serious criterion (for example, hospitalisation) must 
be indicated on the Serious Adverse Event Form. 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.
11.3
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 IMP; action 
taken; and outcome. 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 (section 11.4).
Adverse events, including clinically significant out-of-range clinical safety laboratory test
values and findings from for example, ECGs, must be recorded individually, except when 

H. Lundbeck A/S 
Confidential
Page 64 of 86
considered manifestations of the same medical condition or disease state; in such cases, they 
must be recorded under a single diagnosis.
11.4
Reporting Serious Adverse Events
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 report 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:
Global Pharmacovigilance (GPV)
Fax: +45 36 30 99 67
e-mail: safety@lundbeck.com
Lundbeck will assume responsibility for reporting SAEs to the authorities in accordance with 
local regulations.
It is the investigator’s responsibility to be familiar with local requirements regarding reporting 
SAEs to the IEC or IRB and to act accordingly.
Lundbeck will assume responsibility for reporting SUSARs to the authorities in accordance 
with local regulations. In those Member States of the European Union that have implemented 
the European Union Clinical Trials Directive58 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 ethics committees.
Lundbeck will assess the expectedness of SAEs and inform the investigator(s) about 
SUSARs, at a minimum, in the monthly, blinded SUSAR listings. CIOMS-I reports for 
SUSARS are not normally distributed to investigators in those countries where SUSAR 
listings are sufficient. However, if the CIOMS-I reports are required (for example, by the 
local EC/IRB/REB), they will be sent to the investigator.
11.5
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.
Non-serious adverse events must be followed up until resolution or the safety follow-up 
assessment, whichever comes first. At the safety follow-up, information on new SAEs, if any, 
and stop dates for previously reported adverse events must be recorded.

H. Lundbeck A/S 
Confidential
Page 65 of 86
It is the responsibility of the investigator to follow up on all SAEs until the patient has 
recovered, stabilised, or recovered with sequelae, and to report to Lundbeck all relevant new 
information using the same procedures and timelines as those for the initial report. Relevant 
information includes discharge summaries, autopsy reports, and medical consultations.
SAEs that are spontaneously reported by a patient to the investigator after the safety follow-
up assessment must be handled in the same manner as SAEs that occur during the study. 
These SAEs will be captured in the GPV database.
Patients with clinically significant out-of-range clinical safety laboratory test values at the 
Completion or Withdrawal Visit must be followed in accordance with usual clinical practice 
and be scheduled for a Safety Follow-up Visit to allow for a medical examination and/or 
blood sampling (see section 8.6).
Patients who withdraw due to elevated AST or ALT values (see section 5.4) must be followed 
until the values normalise or stabilise or a diagnosis or a reasonable explanation has been 
established. Additional medical examinations (for example, ultrasound scanning and/or 
sampling for serology, conjugated bilirubin, INR) should be considered. A gastroenterology 
or hepatology consultation should also be considered.
Data Monitoring Committee
The Data Monitoring Committee (DMC) includes child and adolescent psychiatrists. The 
DMC ensures that the ethical principles are observed and monitors the safety of the patients. 
The DMC will be informed to what extent the data and analyses provided to them have been 
quality controlled. Members of the DMC will not be involved in other study-related tasks. 
The details of the DMC procedures are described in the Data Monitoring Committee Charter.
The same DMC will cover all the clinical studies in the paediatric vortioxetine program.
12 Data Handling and Record Keeping
12.1
Data Collection
12.1.1
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 12.1.3.
The eCRFs use third party software (Rave®) to capture data via an on-line system on a 
computer. Data related to the study 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.

H. Lundbeck A/S 
Confidential
Page 66 of 86
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 CRA. All entries, corrections, and changes must 
be made by the investigator or a delegate.
12.1.2
Patient Binders
12.1.2.1
Use of Patient Binders
Lundbeck will provide a Patient Binder for each patient.  The Patient Binder contains
different types of source documents, organised by visit and type. A ballpoint pen with 
waterproof ink must be used to enter information in the Patient Binder.
12.1.2.2
Rating Scales and Patient-reported Outcomes (PROs)
The Patient Binder contains paper versions of the rating scale, K-SADS-PL, the 
neurocognitive test, SDTM and the PRO, PedsQL VAS. They will be completed by the 
rater(s) and the patient, respectively. The data will be transcribed to the Scoring Sheets in the 
eCRF by the investigator or a delegate.
The rater(s) must verify that all the entries in the Scale Section are accurate and correct by 
signing and dating the relevant pages.
The patients will be asked to complete the PROs in their local language. The patients’ 
responses may only be corrected by the patient.
12.1.2.3
Serious Adverse Event Fallback Forms
Serious Adverse Event Fallback Forms must be used when the eCRF cannot be accessed.
12.1.3
External Data
All electronic data will be transferred using a secure method accepted by Lundbeck.
The clinical safety and/or efficacy laboratory test results will be transferred by the central 
laboratory. The data will be loaded into the eCRF.
The electronic data received from the following vendors will be kept in a secure designated 
storage area outside the eCRF:
• In case of any electronic Assessment(s) /PRO(s) the results will be transferred by
designated vendor.
• The results of the IMP analysis will be transferred by Lundbeck Department of Bioanalysis
• The ECG results will be transferred by the central ECG laboratory.

12.2
Retention of Study Documents at the Site
12.2.1
eCRF Data
If a site closes before the study has been completed, the investigator will continue to have 
read-only access to the eCRF. If a site closes after the study has been completed, the 
investigator will no longer have read access to the eCRF. Instead, each site will be provided 
with a CD-ROM containing the data related to the site (including eCRF data, queries, and the 
audit trail). As a CD-ROM is not considered a durable medium and may therefore not be 
readable for the full retention period (for example, 15 years [if required by the applicable 
regulatory requirements]), it is possible for the investigator to request a new CD-ROM with 
the data related to the site.
12.2.2
Other Study Documents
The investigator must keep the investigator’s set of documents in the investigator TMF for at 
least 15 years after the Clinical Study Report has been approved or in accordance with 
national requirements, whichever is longer.
Since 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.
Lundbeck will notify the investigator in writing when the required storage period has expired 
and when the documents may be destroyed according to regulations.
13 Monitoring Procedures
Prior to including patients 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 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 

H. Lundbeck A/S 
Confidential
Page 68 of 86
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, analyse, and verify any records and 
reports that are important for the evaluation of the study.
In this study a Risk Based Monitoring approach will be applied.
14 Audits and Inspections
Authorised personnel from Global Clinical Quality Assurance at Lundbeck 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 patients must be informed that authorised personnel from Lundbeck may wish to review
their medical records. The investigator must be aware and the patients must be informed 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 copy relevant parts of medical 
records. No personal identification apart from the screening or randomisation number will 
appear on these copies.
Patient data will not be disclosed to unauthorised third parties, and patient confidentiality will 
be maintained at all times.
15 Protocol Compliance
Lundbeck has a “no-waiver” policy, which means that permission will not be given to deviate 
from the protocol.
If deviations occur, the investigator must inform the CRA and they must review, discuss, and 
document the implications of the deviation.

H. Lundbeck A/S 
Confidential
Page 69 of 86
16 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 other studies
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 analysis changes after the termination of the study, 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.

18 Statistical Methodology
18.1
Responsibilities
The Department of Biostatistics, H. Lundbeck A/S will perform the statistical analyses 
described below.
18.2
Analysis Sets
• The following analysis sets will be used to analyse and present the data:
all-patients-enrolled (APES) – all patients enrolled to the 4-week Single-blind period 
(Phase A) who received at least one dose of IMP 
all-patients-randomised Phase B (APRS) – all patients randomised to the double-blind, 
8-week treatment period (Phase B)  
all-patients-treated set Phase B (APTS) – all patients randomised to the double-blind, 
8-week treatment period (Phase B) who took at least one dose of double-blind IMP 
full-analysis set Phase B (FAS) – all patients in the APTS who had a valid Baseline B 
assessment and at least one valid post-Baseline B assessment of the CDRS-R total score.
• The patients and data will be classified according to these definitions at a Classification 
Meeting held after all the data have been entered in the study database and before the blind
has been broken.
• The efficacy analysis will be based on the FAS.
18.3
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 
and counts and, if relevant, percentages will be presented for categorical variables.
18.4
Patient Disposition
Patient disposition will be summarised by treatment group and include the number of patients 
who completed and the number of patients who withdrew from treatment, as well as the 
number of patients in each analysis set (APES, APRS, APTS, and FAS).
The number of patients who withdrew from treatment will be summarised by treatment group 
and primary reason for withdrawal as well as by treatment group and all reasons for 
withdrawal.
Patient disposition and demographics will be summarised using descriptive statistics.

Confidential
Page 72 of 86
18.5
Demographics and Other Baseline Characteristics
Demographics (sex, age, race), other baseline characteristics (height, weight and BMI), and 
baseline efficacy variables will be summarised by treatment group. 
18.6
Recent and Concomitant Medication
Recent and concomitant medication will be summarised by anatomical therapeutic chemical 
(ATC) code and generic drug name by treatment group.
18.7
Exposure and Compliance
Exposure and compliance will be calculated per patient and summarised by treatment group.
18.8
Efficacy Analyses
18.8.1
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.
18.8.2
Analysis of the Primary Endpoint
For the primary endpoint (change from Baseline B in the CDRS-R total score to Week 8 in 
phase B (Week 12)), comparisons of the pooled doses of vortioxetine 10 and 20 mg/day 
versus placebo will be made using Mixed Model Repeated Measurements (MMRM) with 
freely varying mean and covariance structure and with country as a fixed factor and Baseline 
B CDRS-R score as a covariate interacting with visit. Treatment (vortioxetine 10 mg/day, 
vortioxetine 20 mg/day, fluoxetine, and placebo) is included as a fixed factor interacting with 
visit. For the primary endpoint a contrast test with weights 0.5, 0.5, 0, and -1, respectively, to 
estimate the average effect of the pooled doses of vortioxetine against placebo, based on the 
LSMeans for the treatment by visit interaction at Week 8 in phase B (Week 12). This will be 
evaluated at a two-sided 5% significance level. Subsequently each vortioxetine dose will be 
tested separately against placebo using a two-sided 5% significance level. To adjust for 
multiplicity a closed testing strategy is applied where statistical significance can be claimed 
on the individual doses only if significance is claimed for the pooled vortioxetine doses.1
18.8.3
Sensitivity Analyses of the Primary Endpoint
The primary endpoint will also be analysed using an analysis of covariance (ANCOVA, OC 
and last observation carried forward [LOCF]) as sensitivity analysis. The Missing at Random 
assumption behind the MMRM model will be investigated. This sensitivity analysis will be 
performed with a) the same covariates and factors as the primary analysis and b) with age, 
weight and height as covariates as well.

Page 73 of 86
18.8.4
Testing Strategy
First the comparison of the pooled doses of vortioxetine to placebo will be tested at a two-
sided 5% significance level. Subsequently each vortioxetine dose will be tested separately 
against placebo using a two-sided 5% significance level. To adjust for multiplicity a closed 
testing strategy is applied where statistical significance can be claimed on the individual doses 
only if significance is claimed for the pooled vortioxetine doses.1
18.8.5
Analysis of the Secondary Endpoints
For continuous endpoints, the same methodology as the primary analysis described for the 
primary endpoint will be used. In addition ANCOVA will be performed (OC and LOCF).
For dichotomous endpoints, such as response and remission, logistic regression with 
treatment as a factor and the baseline score as a covariate will be used. This will be done 
based on OC, LOCF and NRI.
The potential treatment effect on cognitive dysfunction will be separated into a direct effect 
and an indirect effect that is mediated through an improvement in depression. These effects 
will be estimated using two ANCOVA models. In the first model the change from baseline in 
SDMT (number of correct digits) is the dependent variable, while change from baseline 
CDRS-R total score is included as a covariate and treatment as a factor. This model gives an 
estimate of the direct effect. In the second ANCOVA model change from baseline CDRS-R 
total score is the dependent variable while treatment is a factor. Combining the estimated 
treatment effect in this model with the relation between CDRS-R and SDMT in the first 
model gives an estimate of the indirect effect. Finally, the estimated direct and indirect effects 
will be expressed as proportions of the total effect. The analyses are performed using change 
from Baseline B after 4 Weeks of treatment and after 8 weeks of treatment as endpoint, 
respectively. Also, both OC and LOCF are considered.  
18.8.6
Analysis of the Exploratory Endpoints
For continuous endpoints, the same methodology as the primary analysis described for the 
primary endpoint will be used. In addition ANCOVA will be performed (OC and LOCF).
18.9
Pharmacokinetic Analyses
Sparse sampling (2 time points) for vortioxetine and fluoxetine quantification will be 
performed but population PK will be applied for vortioxetine only. Plasma concentrations of 
fluoxetine will be listed. The population PK of vortioxetine will be assessed by means of 
nonlinear mixed effect modelling and the results from the analysis will be reported in a 
separate population PK report.

18.10 Safety Analyses
18.10.1 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 summarised 
by treatment group.
The safety analyses will be based on the APES and the APTS.
Adverse events will be summarised using descriptive statistics. Adverse events from Phase A 
will be reported separately as will adverse events and other safety endpoints from Phase B. 
Allocation of TEAEs to Treatment Periods
TEAEs may be allocated into study periods (these will be defined in the Statistical Analysis 
Plan).
18.10.2 Analysis of Other Safety Endpoints
The clinical safety laboratory test values, vital signs, and ECG parameters will be summarised 
by treatment group. Potentially clinically significant (PCS) values will be flagged and 
summarised.
- Adverse events, PAERS scores, clinical safety laboratory tests, vital signs, weight/BMI, 
ECG parameters, physical examinations, GBI scores (using the 10-item mania subscale), and 
C-SSRS scores will be summarised using descriptive statistics. Adverse events and other 
safety endpoints will be reported separately for Phase A and Phase B.
18.11 Interim Analyses
No interim analyses for efficacy are planned. A DMC will monitor safety data at regular 
intervals to be specified in the Data Monitoring Committee Charter.
To ensure that the study is sufficiently powered an estimate of the variability of the primary 
endpoint and the withdrawal rate will be obtained. The analysis will be performed after at
least 75% of the initially planned randomised patients have either completed or withdrawn 
from the study and will be based on blinded and pooled data from all groups. Based on these 
estimates the power calculation will be updated and adequate actions will be taken if the study 
has lost power.

Since all analyses are done with blinded data, there is no inflation of the Type 1 error rate and 
no alpha adjustment is necessary.
18.12 Sample Size and Power
Assuming a standard deviation (SD) of 11 on the treatment comparisons for the primary 
endpoint and a withdrawal rate of 15-20%, then randomising 120 patients per group and 
applying a closed testing procedure to keep the overall significance level at 5% will provide a 
power of at least 85% for claiming significance of the pooled vortioxetine doses if both doses 
have an effect of 4 points at Week 8 in Phase B (Week 12).
The blinded sample size reassessment will ensure that the power of at least 85% is maintained 
in the study.
18.13 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 the Department of Biostatistics, H. Lundbeck A/S
before the study is unblinded.
