Amendment 2 Summary of Changes
The Amendment 1 protocol, dated 12 Feb 2020, has been amended to reflect the 
following changes:
1. During the COVID-19 pandemic, remote study visits are possible to avoid 
missing efficacy data but are not preferred over clinic visits. 
2. Considering the coronavirus disease 2019 (COVID-19) pandemic, the benefit and 
risk to patients participating in this study has been re-evaluated. Based on the 
limited information to date, no additional risk to study participants is anticipated 
with the use of the investigational product.
3. Updated Section 9.7.8 (Interim Analysis) to reflect that the interim futility 
analysis has now been performed, after 62% of randomized patients completed or 
discontinued the study.
Remote Study Visits:
Investigators/appropriately designated study staff will be allowed to perform selected 
study procedures as remote study assessments (eg, conducted via phone, video 
conference) if participants are unable to attend in-person due to the COVID-19 pandemic. 
During these remote study visits, the supplemental Schedule of Visits and Procedures for 
Remote Study Visits below should be followed and documented that the visit was 
conducted remotely due to COVID-19 pandemic issues.
Safety Assessments: 
Safety assessments permitted to be completed remotely include assessment of adverse 
events and concomitant medications. The Columbia-Suicide Severity Rating Scale 
(C-SSRS) may be performed remotely, and any positive results will be reviewed with an 
Investigator-delegated clinician to ensure the participant is not at risk for suicide. Lab 
draws (PK, pregnancy testing and safety labs), ECG, physical exam and vital signs will 
need to be collected by an appropriate healthcare professional from the site or captured as 
a deviation if it is not possible to collect these data.
Efficacy Assessments:
Due to the nature of the participant CDRS-R assessment, the interview may be performed 
remotely provided that the participant has access to a videoconferencing platform where 
the rating clinician can visually see the participant during the discussion. The 
parent/caregiver CDRS-R interview may be conducted via phone or videoconferencing.
Study Medication Dispensation for Remote Study Visits:
If it is necessary to conduct any part of a visit remotely, resulting in Study Medication not 
being able to be dispensed to the patient at the study site, the option to have study 
medication delivered by courier direct-to-patient (DTP) may be possible. Approval by the 
Sponsor for DTP will need to be obtained from the Study Site each time DTP is utilized.
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Amendment 1 Summary of Changes
The original protocol, dated 02 Mar 2018, has been amended to reflect the following 
changes:
1. Clarification that pharmacokinetic samples will only be collected in patients aged 
7 to 11 years old.
2. Clarification that participants from Study LVM-MD-11 are excluded from 
participating in this study.
3. Updated exclusion item #2 to replace the term “mental retardation” with 
“intellectual disability” per the category in the Diagnostic and Statistical Manual 
of Mental Disorders, 5th Edition.
4. Added interim futility analysis for when approximately 50% of randomized 
patients have either completed or discontinued the study.

SYNOPSIS AND SCHEDULE OF EVALUATIONS
CLINICAL STUDY SYNOPSIS: Study LVM-MD-14
Title of Study
A Double-blind, Placebo- and Active-controlled Evaluation of the 
Safety and Efficacy of Levomilnacipran ER in Pediatric Patients
7-17 Years With Major Depressive Disorder 
Study Centers
Approximately 60 study centers
Development Phase
3
Objective
To evaluate the efficacy, safety, and tolerability of levomilnacipran 
compared with placebo in pediatric outpatients (7-17 years) with 
major depressive disorder (MDD). 
In addition, the study is designed to obtain pharmacokinetic (PK) data 
to define the PK profile of levomilnacipran in the pediatric population 
(7-17 years of age).
Methodology
Multicenter, randomized, double-blind, placebo- and active-
controlled, flexible-dose, parallel group study
During the coronavirus disease 2019 (COVID-19) pandemic, remote 
study visits were implemented and will continue to be possible to 
avoid missing efficacy but are not preferred over clinic visits. The 
study center needs to alert the Sponsor, ahead of time when possible, 
that a remote procedure was performed.
Number of Patients
480 planned (160 placebo, 160 levomilnacipran, and 160 fluoxetine) 
Diagnosis and 
Main Criteria for Inclusion
Male and female outpatients, 7 to 17 years of age (inclusive), who 
meet Diagnostic and Statistical Manual of Mental Disorders, 5th
Edition (DSM-5) criteria for MDD; have a score of  ≥ 40 on the 
Children’s Depression Rating Scale–Revised (CDRS-R) at Visits 1 
and 2, and Clinical Global Impressions-Severity (CGI-S) score ≥ 4 at 
Visits 1 and 2. The Kiddie Schedule for Affective Disorders–Present 
and Lifetime (K-SADS–PL) will be used to confirm the diagnosis of 
MDD and to document the patient’s psychiatric history.
Test Product, Dosage, and Mode 
of Administration
Encapsulated levomilnacipran extended-release (ER) 10 mg
(nontrade), 20 mg, and 40 mg capsules; once-daily oral 
administration, at the same time each day
Duration of Study
!
10 weeks in duration: 1-week screening/washout period, 
followed by an 8-week double-blind treatment period and a 
1-week double-blind down-taper period
Reference Therapy, Dosage, and 
Mode of Administration
Placebo capsules, once-daily oral administration, at the same time 
each day
Encapsulated fluoxetine 10 mg capsules and encapsulated fluoxetine 
20 mg capsules; once-daily oral administration, at the same time each 
day
Criteria for Evaluation
Primary Outcome Measure
CDRS-R change from baseline at Week 8
Secondary Outcome Measure
CGI-S change from baseline at Week 8
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14

Safety Measures
Adverse event (AE) recording, clinical laboratory tests, vital sign 
measurements including height and weight, electrocardiograms 
(ECGs), physical examinations, and Columbia–Suicide Severity 
Rating Scale (C-SSRS)
Pharmacokinetic Analysis
The population PK of levomilnacipran will be characterized using 
plasma concentration-time data. The maximum plasma drug 
concentration, area under the curve, time of maximum plasma 
concentration, half-life, apparent oral clearance and/or apparent 
volume of distribution for levomilnacipran ER will be estimated and 
a summary will be reported.
Statistical Methods
The primary efficacy parameter is the change from baseline to end of 
Week 8 of the double-blind treatment period in the CDRS-R total 
score.
The primary analysis will be performed using a mixed-effects model 
for repeated measures (MMRM) with treatment group, study center, 
visit, and treatment group–by-visit interaction as the fixed effects and 
the baseline value and baseline value–by-visit interaction as the 
covariates. An unstructured covariance matrix will be used to model 
the covariance of within-patient scores. This analysis will be 
performed based on all postbaseline scores using only the observed 
cases without imputation of missing values.
The secondary efficacy parameter is the change from baseline to end 
of Week 8 of the double-blind treatment period in CGI-S. This 
parameter will be analyzed using an MMRM similarly to the primary 
efficacy parameter. 
All safety parameters will be analyzed descriptively. The safety 
analysis will be performed using the Safety Population, defined as all 
randomized patients who received at least 1 dose of the 
investigational product. Efficacy analyses will be performed using the 
Intent-to-Treat (ITT) Population, defined as all patients in the Safety 
Population who had the baseline and at least 1 postbaseline 
assessment of CDRS-R total score.
Population PK parameters will be estimated using nonlinear 
mixed-effects modeling methods. The study will be prospectively 
powered to target a 95% confidence interval within 60% and 140% of 
the geometric mean estimates of clearance and volume of distribution 
for levomilnacipran ER, with at least 80% power.

Note: If necessary, visits may be conducted up to 3 days before or after scheduled visits relative to the Baseline Visit 
(Visit 2). 
a
After assent and consent are obtained, the screening period may be up to 5 weeks in duration, as described in 
Section 9.5.5.
b
Visit 8 assessments to be completed for all randomized patients who complete the study or discontinue before
Week 8.
c
All randomized patients must complete Visit 8/ET and, at the end of the down-taper period, return for 
Visit 9/SFU. Patients who do not enter the down-taper period must return for Visit 9/SFU approximately 1 week 
after Visit 8/ET Visit.
d
If the parent(s), guardian, or legally authorized representative (LAR) is also the patient’s caregiver, he/she will be 
asked to sign both the parent and caregiver consents.
e
May be repeated at the Investigator’s discretion before Visit 2.
f
A pregnancy test will be obtained for female patients of childbearing potential only. 
g
Height will be recorded at Screening (Visit 1) and Visit 8/ET using a stadiometer.
h
K-SADS-PL data will be retained as source documents at the site.
i
PK only collected on participants aged 7-11 years. Sparse PK blood samples will be collected during Visit 5 (at 
predose and 1-4 hour postdose), Visit 6 (4-6 hours postdose), and Visit 7 (6-8 hours postdose). At Visit 5, or at 
any 24-hour period between Visit 5 and Visit 7, inclusive, serial blood samples will be collected from a subset of 
consented 7-11-year-old patients instead of sparse PK samples at the following time points: predose [20-24 hours 
after the most recent dose], and 2, 4, 6, 8, 10-12, and 24-hours postdose. Refer to Section 9.5.3 for additional 
details.

In the event of a state of emergency due to the COVID-19 pandemic leading to 
difficulties in performing protocol-specified procedures, the Sponsor will engage with 
study site personnel in efforts to ensure the safety of patients, maintain protocol 
compliance, and minimize risks to the integrity of the study while trying to best manage 
patient continuity of care. This may include alternative methods for assessments 
(eg, phone contacts or virtual site visits), and shipping investigational product and/or 
supplies direct to patients to ensure continuity of treatment where allowed. In all cases, 
these alternative measures must be allowed by local regulations and permitted by 
IRB/IEC. Investigators should notify the Sponsor if any urgent safety measures are taken 
to protect the patients against any immediate hazard.
5.3
PATIENT INFORMATION AND INFORMED CONSENT
After being given an explanation of the study and before participating in any study 
procedures, each patient, if developmentally appropriate, must provide written assent, and 
his or her parent(s), legal guardian(s), or legally authorized representative (LAR) 
(hereafter referred to as parent/guardian/LAR) must provide voluntary and written 
informed consent in compliance with 21 CFR, Parts 50 and 312 and give HIPAA 
authorization (or an equivalent of HIPAA authorization in non-US countries). 
The signed documents will be placed in the Investigator’s study files. A unique patient 
identification (PID) number will be assigned.
5.3.1
Patient Assent Form
To participate in the study, the patient will read, assent understanding of, sign the assent 
form, and be made aware they can withdraw from the study at any time. Patients who are 
unable to read the assent form will have the statements read to them. If the patient cannot 
sign the form, a witness will be allowed to provide written verification of oral assent. A 
copy of the signed assent will be given to the patient’s parent/guardian/LAR. 
5.3.2
Parent, Legal Guardian, and Legally Authorized Representative 
Informed Consent
Written informed consent will be obtained from the patient’s parent/guardian/LAR before 
the patient participates in any study-related procedure. To provide consent for the 
patient’s participation in the study, the patient’s parent/guardian/LAR will read, assent to 
an understanding of, and sign an instrument of informed consent or other locally 
applicable regulations and authorization form after having had an opportunity to discuss 
the forms with the Investigator before signing. The parent/guardian/LAR will be made 
aware that the patient may withdraw from the study at any time and will receive a copy of 
the signed ICF. Patients who reach the age of majority (ie, 18 years of age in most 
jurisdictions) during the course of the study, are required to be re-consented.

INTRODUCTION
Major depressive disorder (MDD) is a common and serious illness in children and 
adolescents. Epidemiological studies and clinical samples estimate the prevalence of 
MDD as approximately 1%-2% of prepubertal children, and between 3% and 8% of 
adolescents (Zalsman 2006). By the ages of 10 to 15, girls appear to be more likely to 
experience depression than boys (Angold 1998).
MDD is commonly associated with feelings of worthlessness, low self-esteem, and 
thoughts of suicide and its psychosocial burden in the formative years can compromise 
the developmental process. Patients also experience difficulties with concentration and 
motivation, impairing functioning in this critical period. Each year as many as 20% of 
adolescents have suicidal ideation and 9% attempt suicide (Grunbaum JA 2002). Suicide 
is a leading cause of death in adolescents and is a major public health concern 
(CDC 2014). A major risk factor for suicide in adolescents is major depression.
MDD in children and adolescents can be chronic and recurrent. The mean length of 
pediatric depressive episodes is approximately 7 months, and in the course of a first 
episode, up to 40% of patients appear to recover without specific treatment. However, 
patients who do not recover appear to be at high risk of chronic depression, and those 
who do recover have high rates of recurrence and dysthymia (Zalsman 2006).
As a pharmacological treatment, the use of selective serotonin reuptake inhibitors 
(SSRIs) for children and adults increased approximately 7-fold during the 1990s. 
Fluoxetine (Prozac®), an SSRI, is approved by the FDA for the treatment of MDD in 
children and adolescents 8 years and older. Escitalopram (Lexapro®), another SSRI, is 
approved for the treatment of MDD in patients aged 12 and over. Currently, no serotonin 
and norepinephrine reuptake inhibitors (SNRIs) have been approved for the treatment of 
MDD in children or adolescents.
Levomilnacipran is an SNRI approved for the treatment of MDD in adults in the United 
States. The pharmacologic mechanism of the antidepressant activity of levomilnacipran 
and other SNRIs (ie, duloxetine, venlafaxine, and desvenlafaxine) is thought to be 
mediated through inhibition of norepinephrine (NE) and 5-hydroxytryptamine (serotonin) 
(5-HT) reuptake in the central nervous system. Although all SNRIs (as a class) block 
5-HT and NE reuptake, currently marketed SNRIs (duloxetine, venlafaxine, and 
desvenlafaxine) are more potent inhibitors of 5-HT reuptake than of NE reuptake 
(Deecher 2006; Vaishnavi 2004). Levomilnacipran exhibits a distinct in vitro profile, 
exhibiting more potent inhibition of NE reuptake than 5-HT reuptake (Auclair 2013). 
This greater potency at the NE transporter may confer additional improvements 
specifically in those domains associated with noradrenergic neurotransmission; for 
example: alertness, energy, attention, and anhedonia (Montgomery and Briley, 2011).
Approval Date: 05-Aug-2020 10:42:17 (GMT)

The efficacy of levomilnacipran as measured by the Montgomery-Åsberg Depression 
Rating Scale total score was established in 3 pivotal studies of adult patients with MDD. 
Levomilnacipran also demonstrated superiority over placebo as measured by
improvement in the Sheehan Disability Scale functional impairment total score. These 
studies, which were conducted in the United States and Canada, were placebo-controlled; 
no active comparator was included. Two of the studies were fixed-dose studies 
(LVM-MD-01: placebo, levomilnacipran 40 mg/day, 80 mg/day, and 120 mg/day; and 
LVM-MD-10: placebo, levomilnacipran 40 and 80 mg/day) and 1 study was
flexible-dose (LVM-MD-03: placebo, levomilnacipran 40 mg/day to 120 mg/day).
In summary, MDD is a condition common in children and adolescents and is a major 
public health concern. Current approved treatment options for this condition are limited 
to the 2 aforementioned SSRI products. Since the modulation of energy, vigilance, and 
arousal can be directly linked to the noradrenergic system, it has been suggested that 
antidepressants with a prominent noradrenergic component, such as levomilnacipran, 
may be particularly effective in addressing functional impairment, decreased 
concentration, lassitude, mental and physical slowing, and decreased self-care 
(Citrome 2013). Brain serotonin and norepinephrine systems continue to mature through 
childhood and adolescence, however, and these maturational effects may generate 
age-related differences in patients’ responses to pharmacotherapy. Thus, it is important 
that further investigation of SNRI treatment options such as levomilnacipran be evaluated 
systematically for the treatment of MDD in children and adolescents, so that an SNRI’s 
efficacy and safety profile can be characterized in this population.
The current study of levomilnacipran extended release (ER) in pediatric patients 
(7-17 years old) with MDD will be conducted as required under the Pediatric Research 
Equity Act and as agreed upon with the FDA as a part of Postmarketing Requirement 
studies.

INVESTIGATIONAL PLAN
9.1
OVERALL STUDY DESIGN AND PLAN: DESCRIPTION
Study LVM-MD-14 will be a multicenter, randomized, double-blind, placebo- and 
active-controlled, flexible-dose, parallel group study in pediatric patients, ages 
7-17 years. The study will be approximately 10 weeks in duration:
!
1-week screening/washout period
!
8-week double-blind treatment period 
!
1-week double-blind down-taper period 
The screening/washout period will be generally 1 week (± 3 days) prior to Visit 2
(Baseline), but may be extended up to a total of 5 weeks to accommodate prior 
medication washout or to repeat assessments. Patients will not receive any investigational 
product during the screening period. 
Patients who meet the eligibility criteria at Visit 2 (Baseline) will be randomized to 1 of 
3 treatment groups: placebo, levomilnacipran, or fluoxetine. See Section 9.4.5 for details 
regarding dose selection and timing. 
All randomized patients who complete the 8-week double-blind treatment period and 
patients who prematurely discontinue from the study before completing 8 weeks of 
double-blind treatment should enter the 1-week, double-blind down-taper period unless it 
is considered not clinically appropriate by the Investigator. 
All randomized patients must complete Visit 8/Early Termination (ET) Visit and, at the 
end of the down-taper period, return for Visit 9/Safety Follow-up (SFU) Visit. Patients 
who do not enter the down-taper period must return for Visit 9/SFU Visit approximately 
1 week after Visit 8/ET Visit.
Approximately 480 patients (160 per treatment group) are planned to be randomized in 
the study.
Figure 9-1 provides a schematic of the study design. 
The coronavirus disease 2019 (COVID-19) pandemic developed after this study began,
and this protocol has been amended to account for study procedures that may need to be 
modified in association with adhering to local guidelines or regulations or site flexibility 
to complete study-required procedures.

During the COVID-19 pandemic, remote study visits, in which data are collected via 
phone or videoconference, were and will continue to be possible when needed. To 
accommodate changes that sites may need to implement during the pandemic, Section 2.0
outlines the conduct of study assessments during on-site clinic visits, which is the 
preferred method of conducting the study, while study assessments for remote visits are 
included in Section 2.1. Sites will need to inform the Sponsor of the need for a remote 
visit in advance whenever possible.
In the event that it is required to perform procedures remotely, every effort should be 
made to perform the remote assessment in a manner as similar as possible to the on-site 
assessment. Patient data collected via phone or video conferencing should remain 
consistent with either method for each patient.
Detailed descriptions of each study visit are provided in Section 9.5.5.

Protocol LVM-MD-14
Allergan Sales, LLC

2020
Visit conduct options will allow remote visits as outlined below:
!
Option 1: In-clinic visits 
This is the preferred option. All study visits are performed as in clinic visits with all 
assessments outlined in the Schedule of Assessments in Section 2.0.
!
Option 2: Remote visits (except screening) 
This option is only to be used if local guidance, regulations, or the needs of the patient
prevent the site or the patient from completing on-site visit procedures. Screening visits 
must take place as an in-clinic visit with all assessments outlined in the schedule of 
assessments in Section 2.0. All other visit procedures (V2-V8) can be completed 
remotely with the assessments outlined in Section 2.1. The study center needs to alert the 
Sponsor, ahead of time when possible, that a remote procedure was performed.
For remote visits, there is an option to have study drug delivered by preferred courier. 
Approval from the Sponsor study team must be obtained from the study center each time 
the preferred courier service is utilized. 
9.2
DISCUSSION OF STUDY DESIGN, INCLUDING THE CHOICE 
OF CONTROL GROUPS
This placebo- and active-controlled, flexible-dose design with an 8-week double-blind 
treatment period was chosen based on prior studies that established the efficacy and 
safety of levomilnacipran in adult patients with MDD. In this study, Investigators must 
use a valid and reliable diagnostic method for recruiting and enrolling children and 
adolescents meeting Diagnostic and Statistical Manual of Mental Disorders, 5th Edition 
(DSM-5; American Psychiatric Association 2013) criteria for MDD.
A placebo arm is included for comparison since placebo-controlled superiority trials have 
been shown to be conducive to higher quality studies and to provide more reliable 
outcomes than non-inferiority comparisons to a previously approved drug (Feifel 2008; 
Laughren 2001; Gispen-de Wied 2012). In addition, placebo in place of the (limited) 
standard therapy should not cause irreversible health problems or extreme suffering 
(depression is recognized by the FDA as a condition in which there is substantial 
improvement and variability in placebo groups; see FDA Guidance for Industry:
E10, May 2001). 
Fluoxetine was selected as an active comparator for assay sensitivity in the present study 
because it is an SSRI approved by the FDA for the treatment of MDD in children and 
adolescents 8 years and older.
In the current study, safety and efficacy assessments are included in every visit to 
determine adequacy of response, safety, and tolerability for all patients.

Removal of Patients from Therapy or Assessment
A premature discontinuation will occur when a patient who gave voluntary assent and/or 
whose parent/guardian/LAR and/or caregiver signed the ICF ceases participation in the
study, regardless of circumstances, before the completion of the study. Patients can be 
prematurely discontinued from the study for any of the following reasons:
!
Screen failure (failure to meet inclusion/exclusion criteria) 
!
Withdrawal by subject
!
Adverse event (AE)
!
Lack of efficacy
!
Protocol deviation
!
Non-compliance with study drug
!
Lost to follow-up
!
Study terminated by Sponsor 
!
Site terminated by Sponsor
!
Other
All randomized patients who prematurely discontinue from the study, regardless of cause, 
should be seen for a final assessment at ET (see Section 9.5.5.6 for details on assessments 
performed at Visit 8/ET). Patients who discontinued from the study and did not return to 
the site for final assessments must be requested in writing to do so and to return any 
unused investigational product. A copy of the letter, together with the source 
documentation, will be kept by the Investigator. The reasons for premature 
discontinuation from the study will be recorded on the Study Disposition Pages of the 
eCRF.
All randomized patients must complete Visit 8/ET Visit and return for Visit 9/SFU at the 
end of the down-taper period. Patients who do not enter the down-taper period must 
return for Visit 9/SFU approximately 1 week after Visit 8/ET Visit.
9.3.4
Patient Replacement Procedures
Patients in this study who prematurely discontinue treatment will not be replaced.

Demographic Considerations
Efforts will be made to have reasonable representation with respect to gender, race, and 
ethnicity, reflecting the proportions in the disease population. AGN will monitor 
enrollment and may instruct the sites accordingly.
9.4
TREATMENTS
Patients meeting the eligibility criteria at Visit 2 (Baseline) will be randomized in a 
double-blind fashion to 1 of 3 treatment groups: placebo, levomilnacipran, or fluoxetine.
9.4.1
Treatments Administered
At Visit 1 (Screening) and after consent/assent is obtained, patients will be given a 
placebo capsule to swallow to confirm their ability to swallow investigational product.
Investigational product in the form of over-encapsulated capsules will be packaged in 
blister cards and provided by AGN. Patients will be supplied with blinded investigational 
product and will be instructed to take 2 capsules orally each morning (see Section 9.4.5
for details). Confirmation that dosing scheme (including titration and down-taper) and 
dosing instructions were discussed with the patient and caregiver, and that dosing 
instructions were provided will be recorded in the source documents.
9.4.2
Identity of Investigational Products
Investigational product will be supplied by AGN as capsules containing placebo or 
nontrade levomilnacipran 10 mg capsules, trade levomilnacipran 20 mg capsules, trade 
levomilnacipran 40 mg capsules, fluoxetine 10 mg capsules, or fluoxetine 20 mg capsules 
packaged in blister cards.
The blister cards will contain sufficient numbers of doses for the interval of days between 
scheduled visits plus additional doses to accommodate visit scheduling. 
The blister cards will be labeled with the protocol number, storage information, warning 
language (viz, “Caution: New Drug—Limited by Federal Law to Investigational Use”), 
and instructions to take as directed. The Investigator will write the date, visit number, 
study week, and PID number on the label.
All investigational product will be provided and shipped to the study centers by AGN and 
must be stored in an appropriate secure area (eg, a locked cabinet in a locked room) at 
room temperature (25°C or 77°F, with a permitted range of 15°C-30°C or 59°F-86°F), 
and must be protected from light, heat, and moisture.
Approval Date: 05-Aug-2020 10:42:17 (GMT)

The Investigator is responsible for recording the receipt and use of all investigational 
product supplied and for ensuring the supervision of the storage and allocation of these 
supplies. All unused investigational product must be returned; and, whenever 
investigational product are returned, unit counts must be performed. All investigational 
product must be accounted for. At the end of the study, all unused investigational product 
and empty investigational product packages must be returned to the Sponsor at the 
address provided in the Study Reference Binder.
9.4.3
Method of Assigning Patients to Treatment Groups
After the patient, parent/guardian/LAR, and caregiver provide assent and sign the ICF at 
Visit 1 (Screening), study personnel will register the patient in the interactive Web 
response system (IWRS), and the system will assign the patient a sequential PID number. 
The first patient entered into the system at each site will be assigned the first number in 
the sequence by the system. This PID number will be used to identify the patient 
throughout the study (ie, at all study phases). 
The study center must contact the IWRS at Baseline (Visit 2) and all subsequent study 
visits in order to obtain the instructions on kit number for the investigational product to 
be dispensed to the patient at that visit. 
A detailed description of IWRS procedures is contained in the IWRS Site User Guide that 
should be stored in the Study Reference Binder.
9.4.4
Selection of Dosages in the Study
Doses of levomilnacipran in pediatric patients (7-17 years of age) were selected based on 
modeling of available PK data submitted with NDA 204,168 from the adult healthy 
volunteers and patients with MDD, as well as adolescent patients (12-17 years of age, 
LVM-MD-11, 2017) with MDD. Based on the results of modeling a common dosing 
scheme for both age groups of 7-11 and 12-17 years is appropriate. While the adolescent 
age group, 12-17 years of age, demonstrates similar plasma concentrations as adults 
administered the same dose of 80 mg/day, for the younger age group, 7-11 years of age, 
data indicate that equivalent concentrations are achieved with approximately a 33% dose 
reduction. Thus, 80 mg/day is expected to show exposure similar to exposures seen for 
the adult population administered 120 mg/day.
Based on the above findings, levomilnacipran 40 mg/day, with an optional increase to 
80 mg/day based on therapeutic response and tolerability, is appropriate for the pediatric 
patient age range (7-17 years of age). The corresponding plasma concentrations of these 
doses in pediatric patients are expected to remain within the plasma concentrations 
associated with the approved therapeutic dose range for adults.

9.4.5
Selection and Timing of Dose for Each Patient
All investigational products should be taken orally as a single dose, once-daily at the 
same time each day. After consent/assent is obtained, patients undergoing screening will 
be required to swallow a placebo capsule to confirm their ability to swallow the 
investigational product, as part of their eligibility assessment.
Patients who meet all eligibility criteria at Visit 1 (Screening) and who continue to meet 
all the eligibility criteria for participation in the study will be assigned a randomization 
number at Visit 2 (Baseline) and dispensed the corresponding blister card containing 
capsules of double-blind investigational product for Week 1. Patients will begin dosing 
with double-blind capsules on the next day. Patients will be instructed to take 2 capsules 
orally as a single dose, once daily at approximately the same time each day 
(morning dosing recommended), with or without food. 
Dosing may be switched from the morning to another time of day if a patient prefers or if 
tolerability issues arise. However, any switch must allow at least 20 hours between 
2 consecutive doses. 
9.4.5.1
Screening Period
At Visit 1 (Screening) after consent/assent is obtained, a placebo capsule will be 
administered for the purpose of eligibility determination. Patients will be given a placebo 
capsule to swallow. If a patient is unable to swallow the placebo capsule, the patient will 
be ineligible for study participation.
9.4.5.2
Double-blind Treatment Period
The titration schedule is as follows:
!
Levomilnacipran: Days 1-3, 10 mg/day; Days 4-7, 20 mg/day; Week 2 through 
Week 8, 40 mg/day; Based on therapeutic response and tolerability, an additional 
dose increase to 80 mg/day is permitted at Week 3.
!
Fluoxetine 20 mg/day (active comparator): Week 1, 10 mg/day; Week 2 through
Week 8, 20 mg/day
Patients will be assigned a randomization number at Visit 2 (Baseline) and dispensed the 
corresponding blister card containing capsules of double-blind investigational product for 
Week 1. Patients will begin dosing with double-blind capsules on the next morning. 
Patients will be instructed to take 2 capsules from each column (1 each from Row A and
Row B) as a single dose daily each morning with or without food. The double-blind 
dosing regimen is presented in Table 9-1.

Patients will be instructed to return the blister card with any remaining investigational 
product, and to return it even if it is empty, preferably at the next study visit. Additional 
investigational product will be dispensed as per the schedule shown in Section 2.0.
If a patient experiences an AE, the investigational product may be stopped for up to a 
maximum of 4 consecutive days. The date and reason for missed doses must be recorded 
on the appropriate page of the eCRF. If appropriate, as deemed by the investigator, 
patient may resume medication at 40 mg/day or reduce to 40 mg/day (if taking 
80 mg/day). Those unable to tolerate 40 mg/day should be discontinued from the study.
9.4.5.3
Double-Blind Down-Taper Period
All randomized patients who complete the 8-week double-blind treatment period and
patients who prematurely discontinue from the study before completing 8 weeks of 
double-blind treatment should enter the 1-week, double-blind down-taper period unless it 
is considered not clinically appropriate by the Investigator. The double-blind 
down-titration regimen is as follows:
!
Levomilnacipran 40 mg/day and 80 mg/day: Days 1-2, 40 mg/day;
Days 3-7, 20 mg/day

Blinding
A list of patient randomization codes will be generated by Statistical Programming at 
AGN and implemented by the IWRS vendor (an electronic version will be stored on a 
secure server). This list will identify each patient by randomization number and include
the patient’s corresponding treatment assignment.
9.4.7
Unblinding
The IWRS will be programmed with blind-breaking instructions. The study blind may be 
broken if, in the opinion of the investigator, it is in the patient’s best interest to know the 
study treatment assignment. The Sponsor must be notified before the blind is broken 
unless identification of the study treatment is required for a medical emergency in which 
the knowledge of the specific blinded study treatment will affect the immediate 
management of the patient’s condition. In this case, the Sponsor must be notified within 
24 hours after breaking the blind. The date and reason that the blind was broken must be 
recorded in the source documentation and eCRF, as applicable.
9.4.8
Prior and Concomitant Therapy
A list of concomitant medications that are allowed and not allowed for either episodic or 
chronic use is provided in Appendix III. Medication history (psychotropic medication 
history during the previous 5 years and all other medications during the past 12 months) 
will be recorded at Visit 1 (Screening) in the eCRF. Thereafter, any changes in 
concomitant medications or new medications added will be recorded in the eCRF.
9.4.9
Monitoring Treatment Compliance
Investigational product compliance during any treatment period will be closely monitored 
by counting the number of capsules dispensed and returned. Before new investigational 
product is dispensed at each visit, every effort will be made to collect all unused 
investigational product. Patients who do not take investigational product for 5 or more 
consecutive days, or consistently demonstrate poor compliance (< 80% or > 120% in 
2 consecutive visit intervals, measured by capsule count) should be considered for study 
discontinuation. Investigators should consult with the Study Physician before 
discontinuing a patient due to poor compliance.
9.4.10
Treatment After Discontinuation
Patients whose MDD symptoms worsen or are determined by the Investigator to be 
inadequately controlled before completing the double-blind treatment period are allowed 
to discontinue investigational product and start appropriate treatment at the Investigator’s 
discretion. This new treatment will not be provided by AGN. Patients who initiate a new 
treatment for MDD must be discontinued from the study.

EFFICACY AND SAFETY VARIABLES
9.5.1
Efficacy Assessments
The efficacy assessments will include the CDRS-R, CGI-S, and Clinician Global 
Impressions-Improvement (CGI-I). Efficacy assessments are not to be administered if the 
patient is not accompanied by his/her consented caregiver. The K-SADS-PL and all 
efficacy assessments will be conducted by experienced clinicians meeting training 
requirements and qualifications standards established by AGN and rater training vendor.
9.5.1.1
Primary Efficacy Assessment
The CDRS-R (Appendix V; Poznanski and Mokros 1996) is a semi-structured, 
clinician-rated instrument designed for use with children and adolescents between the 
ages of 6-17 years and contains 17 ordinally-scaled items that evaluate the presence and 
severity of symptoms commonly associated with childhood depression. The CDRS-R 
total score ranges from 17 to 113. 
The CDRS-R will be administered separately to the patient and to the caregiver. For each 
item, the clinician administering the interviews will select the rating that provides the best 
description of the patient and will then determine the total score.
9.5.1.2
Secondary Efficacy Assessment
The CGI-S (Appendix VI; Guy 1976) is a clinician-rated scale used to rate the severity of 
the patient’s current state of mental illness compared with an MDD patient population. 
The patient will be rated on a scale from 1 to 7, with 1 indicating a “normal, not at all ill” 
and 7 indicating “among the most extremely ill patients.” 
9.5.1.3
Additional Efficacy Assessment
The CGI-I is a clinician-rated instrument (Appendix VII). Based on the Investigator’s 
clinical opinion, the total improvement or worsening of the patient’s mental illness is 
rated on a scale from 1 to 7, with 1 being very much improved and 7 being very much 
worse, relative to Visit 2 (Baseline), regardless of whether the Investigator considers the 
worsening to be related to investigational product.
9.5.2
Safety Assessments
Patients must be evaluated by a physician or an appropriately trained health care 
professional at every visit and the evaluation must be documented. The procedures 
discussed below will be completed at the designated visits. Scheduled safety assessments 
are not to be administered if the patient is not accompanied by his/her consented 
caregiver.

9.5.2.1
Adverse Events
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment. An AE can therefore be any unfavorable and 
unintended sign (including an abnormal laboratory finding, for example), symptom, or 
disease temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product (ICH-E2A).
For the purpose of data collection for this study, any untoward event that was reported 
from the time the patient signed the ICF until 30 days after the last dose of treatment is to 
be considered an AE.
Examples of AEs are as follows:
!
Changes in the general condition of the patient
!
Subjective symptoms offered by or elicited from the patient
!
Objective signs observed by the Investigator or other study center personnel
!
All diseases that occur after signing ICF, including any change in severity or 
frequency of preexisting disease
!
Laboratory values that are deemed to be clinically significant by the Investigator
!
Physical exam findings, including vital sign measurements, that are deemed to be 
clinically significant by the Investigator
Please note that medical procedures scheduled prior to consenting, but occurring during 
the study should not be captured as AEs, but should be listed in the medical history if 
related to a pre-existing condition.
9.5.2.2
Causality Assessment
For each AE, the Investigator must provide an assessment of causal relationship to the 
investigational product. The causality assessment must be recorded on the appropriate AE 
reporting page of the patient’s eCRF. Causal relationship must be assessed by answering 
the following question:
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC
Page 42
2020
Is there a reasonable possibility that the investigational product caused the event?
Yes:
There is evidence to suggest a causal relationship between the investigational 
product and AE, ie:
o
There is a reasonable temporal relationship between the investigational product 
and the event, and/or 
o
The event is unlikely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, and/or
o
Positive dechallenge and/or rechallenge exist
No:
There is no evidence to suggest a causal relationship between the 
investigational product and AE, ie:
o
There is no reasonable temporal relationship between the investigational product 
and the event, or
o
The patient did not take the investigational product, or
o
The event is likely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, or
o
The event is commonly occurring in the (study) population independent of 
investigational product exposure
9.5.2.3
Severity Assessment
The Investigator will provide an assessment of the severity of each AE by recording a 
severity rating on the appropriate AE reporting page of the patient’s eCRF. Severity,
which is a description of the intensity of manifestation of the AE, is distinct from 
seriousness, which implies a patient outcome or AE-required treatment measure 
associated with a threat to life or functionality (Section 9.5.2.4). Severity will be assessed 
according to the following scale:
Mild:
A type of AE that is usually transient and may require only minimal 
treatment or therapeutic intervention. The event does not generally 
interfere with usual activities of daily living
Moderate:
A type of AE that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, 
causing discomfort but poses no significant or permanent risk of harm to 
the research participant
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC
Page 43
2020
Severe:
A type of AE that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention
9.5.2.4
Serious Adverse Events
An SAE is any untoward medical occurrence that at any dose:
!
Results in death
!
Is life threatening
!
Requires inpatient hospitalization or prolongation of existing hospitalization
!
Results in persistent or significant disability/incapacity, or
!
Is a congenital anomaly/birth defect
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based on appropriate medical judgment, 
they may jeopardize the patient or subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions that do not result in patient 
hospitalization, or the development of investigational product dependency or drug abuse.
Emergency room visits that do not result in hospitalization should be evaluated for one of 
the other serious outcomes to determine whether they qualify as SAEs.
Preplanned hospitalizations (eg, elective procedures for preexisting conditions that did 
not worsen, such as cosmetic surgery and hysterectomy) are excluded from SAE 
reporting.
9.5.2.5
Reporting Adverse Events and Serious Adverse Events
At each visit, patients are to be queried regarding any AEs or SAEs that have occurred 
since the previous visit. Patients will be asked to volunteer information with a nonleading 
question such as, “How do you feel since your last visit?” Study center personnel will 
record all pertinent information in the patient’s eCRF. 
In addition, any SAEs reported by the patient (or patient representative) or otherwise 
identified by the Investigator after the study period (ie, after 30 days post last dose) 
should be documented and reported.
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC
Page 44
2020
All AEs must be recorded on the appropriate AE reporting page of the patient’s eCRF 
whether or not they are considered causally related to the investigational product.
For every AE, the Investigator must:
!
Provide an assessment of the seriousness of the event (ie, is it an SAE?), as well as 
the severity and causal relationship
!
Document all actions taken with regard to the investigational product
!
Detail any other treatment measures taken for the AE
!
Document the outcome of the AE
In addition, patients and caregivers are to be reminded, as described in the ICF and in 
accordance with Section 9.5.2.1, to notify site personnel of any AEs occurring during the 
30-day poststudy period. Any AEs reported by the patient (or patient representative) 
during this period are to be recorded in original source documents. AEs are also to be 
recorded in the eCRF if at least one of the following conditions is met: 1) the event meets
the criteria for an SAE (see Sections 9.5.2.4 and 9.5.2.6), and/or 2) the event is judged by 
the Investigator to be potentially causally related to investigational product.
Any AEs that are ongoing at the time of the final protocol-defined study visit will be 
followed until the condition returns to prestudy status, has resolved or stabilized, or can 
be explained as being unrelated to the investigational product. If a follow-up visit is 
deemed necessary for appropriate safety surveillance, it will take place within 30 days of 
the final protocol-defined study visit.
9.5.2.6
Immediate Reporting of Serious Adverse Events and Events of 
Special Interest
AGN is required to inform worldwide regulatory authorities of SAEs that meet specific 
criteria. Therefore, AGN must be notified immediately regarding any SAE that occurs 
after informed consent is obtained.
Within 24 hours of learning of any AE that meets one of the criteria for an SAE, the 
study center personnel must report the event to Global Drug Safety on the SAE Form for 
Clinical Trials. The Study Physician may also be notified by telephone.
If, during follow-up, any nonserious AE worsens and eventually meets the criteria for an 
SAE, that AE should be recorded as a new SAE. 
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC

The study center must transmit the SAE Form for Clinical Trials to the SAE fax number 
shown below. Even if an initial report is made by telephone, the SAE Form for Clinical 
Trials completed with all available details must still be faxed within 24 hours of 
knowledge of the event at the study center.
Supplemental information should be submitted as soon as available and may include 
laboratory results, radiology reports, progress notes, hospital admission and emergency 
room notes, holding and observation notes, discharge summaries, autopsy reports, and 
death certificates.
The Investigator is expected to take all therapeutic measures necessary for resolution of 
the SAE. Any medications or procedures necessary for treatment of the SAE must be 
recorded on the appropriate pages of the patient’s eCRF. All SAEs are to be followed by 
the study staff until resolution or until the SAE is deemed stable. AGN may contact the 
study center to solicit additional information or follow up on the event.
Fax the SAE Form for Clinical Trials to AGN:

Primary: 1-714-796-9504
Back-up: 1-714-246-5295
9.5.2.7
Reporting of Pregnancies Occurring During the Study
Study center personnel must report every pregnancy from the time the patient signs the 
ICF until 30 days after the last dose of investigational product. Within 24 hours of 
learning of a pregnancy, the study center personnel must report the event to Global Drug 
Safety on the Clinical Trial Pregnancy Form and fax it to the SAE/Pregnancy fax number 
stated in Section 9.5.2.6, even if no AE has occurred. Pregnancies in female partners of 
male patients occurring during the time frame described above must also be reported. 
The pregnancy must be followed to term and the outcome reported by completing a 
follow-up Clinical Trial Pregnancy Form. If the pregnancy is associated with an SAE 
(eg, if the mother is hospitalized for hemorrhage), a separate SAE Form for Clinical 
Trials must be filed as described in Section 9.5.2.6 with the appropriate serious criterion 
(eg, hospitalization) indicated in addition to the Pregnancy Form.

Potential Hy’s Law Cases
Potential Hy’s law criteria are:
!
ALT or AST ≥ 3 × ULN AND 
!
Total bilirubin ≥ 2 × ULN AND 
!
Alkaline phosphatase < 2 × ULN
Study center personnel must report every patient who meets these potential criteria. 
Typically, all 3 analytes will be obtained from the same sample, but they may come from 
multiple samples taken within a 24-hour period. This requirement applies from the time 
he or she signs the ICF for the study until 30 days after the final protocol-defined study 
visit or the last known dose of investigational product (if the final visit does not occur). 
A laboratory alert for potential Hy’s laws cases will be in place and the laboratory must 
notify Investigators and AGN immediately when the above criteria have been met. A 
potential Hy’s law case must be faxed to AGN on an AE of Special Interest Form as soon 
as possible (within 24 hours of learning of the potential Hy’s law case) to the 
SAE/Pregnancy fax number stated in Section 9.5.2.6, even if no AE has occurred. The 
eCRF for potential Hy’s law cases must be completed within 7 calendar days. Every 
effort to determine the cause of the liver enzyme abnormalities must be made, and close 
monitoring should be initiated in conjunction with the Study Physician and in accordance 
with the FDA “Guidance for Industry: Drug Induced Liver Injury- Pre-Marketing 
Clinical Evaluation” July 2009.
9.5.2.9
Clinical Laboratory Determinations
Blood and urine samples for clinical laboratory tests will be collected as detailed in the 
Schedule of Evaluations (Section 2.0). During Screening, the Investigator will assess the 
clinical significance of any values that are outside the reference ranges provided by the 
central laboratory; patients with abnormalities judged to be clinically significant will be 
excluded from the study.
Patients will be instructed to fast overnight (for at least 8 hours) before coming in for 
their appointments when clinical laboratory blood tests are to be drawn. If non-fasting, 
an attempt should be made to draw blood at least 4 hours after a meal.
Approval Date: 05-Aug-2020 10:42:17 (GMT)

A UDS will be conducted for all patients at Visit 1 (Screening). A negative UDS for 
prohibited substances (illegal drugs or prohibited concomitant medications [see 
Appendix III and Exclusion Criterion #18]) is required before Visit 2 (Baseline) for the 
patient to continue in the study. Amphetamines can be allowed if prescribed for treatment 
of attention deficit disorder at a dose that is stable for at least 60 days before Visit 1 
(Screening). If not stable for at least 60 days before Visit 1 (Screening), the patient 
should be discontinued. However, the patient can be rescreened on a later date.
Patients who have a positive UDS at Visit 1 (Screening) for other prohibited substances 
(barbiturates, benzodiazepines, opiates, cannabinoids, cocaine, methadone, 
phencyclidine, or other prohibited concomitant medications) may be allowed to enroll if 
(1) there is no suspicion of drug abuse per the Investigator judgment, (2) the use is 
discontinued and (3) this is documented by a negative UDS before Visit 2 (Baseline). If 
the repeat test cannot be performed within 21 days, the patient should be discontinued 
from the study. The patient can be rescreened on a later date and must have a negative 
UDS to be considered for inclusion in the study.
Alcohol consumption is prohibited during the study. A UDS or blood alcohol test may be 
performed at any time during the study at the discretion of the Investigator. A patient 
with a positive blood alcohol test or a positive UDS for any prohibited substances at any 
postrandomization visit may be allowed to continue in the study if approved by the 
Investigator and by the Study Physician.
Females of childbearing potential will be required to have a serum β-hCG pregnancy test 
at Visit 1 (Screening) and Visit 8/ET. Positive pregnancy test results at Visit 1 will 
exclude female patients from participating in the study. At every study visit, Investigators 
should inquire about the use of acceptable methods of contraception in females of 
childbearing potential who are, or become, sexually active, and perform a urine 
pregnancy test if there is any question of non-compliance with contraception. If the urine 
pregnancy test is negative, a serum β-hCG pregnancy test must be performed to rule out 
pregnancy. Any positive pregnancy test results during the study will result in patient 
termination from the study.
The following clinical laboratory levels will be measured:
Hematology:
Absolute and differential white blood cell count, 
erythrocyte count, hemoglobin, hematocrit, platelet count, 
and red blood cell indices (mean corpuscular volume, mean 
corpuscular hemoglobin, and mean corpuscular hemoglobin 
concentration)

(Screening)
UDS:
Benzoylecgonine (cocaine), barbiturates, amphetamines, 
benzodiazepines, cannabinoids, opiates, methadone, 
phencyclidine. UDS will be performed for all patients at 
Visit 1 (Screening). UDS may be repeated during the study 
at the Investigator’s discretion
Blood alcohol level:
Blood alcohol level will be conducted at Visit 1 
(Screening). May be performed at random during the study 
upon request of the Investigator
Serum β-hCG:
Female patients of childbearing potential only. Will be 
performed at Visit 1 (Screening) and for randomized 
patients at Visit 8/ET. Urine pregnancy tests may be 
performed at the discretion of the Investigator at any visit 
during the double-blind treatment period; if negative, 
perform a serum β-hCG test to rule out pregnancy.
Other laboratory assessments may be repeated at any visit if there was an abnormal 
finding at the most recent, previous evaluation or if additional information is clinically 
necessary to appropriately evaluate the patient’s current condition, follow up and/or 
manage an AE. Fasting for at least 8 hours is recommended before unscheduled visits to 
assess serum chemistry.
A central laboratory will be used to evaluate all urine and blood samples, which will be 
collected, processed, and stored according to the instructions provided by the laboratory.

Vital Signs
Vital sign measurements, seated radial pulse rate, seated systolic and diastolic BP, and 
body weight, will be documented at every visit. Pulse and BP readings will be taken 
twice after the patient has been sitting for at least 5 minutes. The second measurement 
will be entered in the eCRF. A BP cuff of appropriate size for the patient should be used. 
The same arm and BP cuff should be used for all BP and radial pulse measurements 
throughout the study.
BP may be measured manually or by machine, but the same method of measurement 
should be used for a patient throughout the study. Radial pulse rate should be measured 
manually. All BP and radial pulse measurements will be recorded in the patient’s source 
documents. 
Patients should be instructed not to wear clothing with tight sleeves when they come to 
have their BP measured. Additionally, they should be kept as calm and undisturbed as 
possible while BP and pulse measurements are taken (ie, there should be no talking while 
the BP is being measured).
Height will be measured as accurately as possible using a stadiometer while the patient is 
standing with no shoes on and recorded at Visit 1 (Screening) and Visit 8/ET. Patients 
should wear their usual indoor clothing, but take off their jacket and shoes during weight 
measurements. For each patient, body weight and height should be determined using the 
same equipment during the study after confirming proper calibration.
9.5.2.11
Electrocardiograms
A 12-lead ECG will be performed at Visit 1 (Screening), Visit 5 (Week 3), and at Visit 8 
(Week 8/ET). The paper speed will be standard 25 mm/sec. ECGs will be electronically 
transmitted for analysis according to the instructions provided by the central ECG 
laboratory. Measurements (in msec) will be recorded for the following parameters in 
lead II or lead III: PR interval, QRS duration, and uncorrected QT interval. QTcF 
(Frederica corrected QT interval) and QTcB (Bazett corrected QT interval) will be 
calculated.
The overall interpretation and determination of the clinical relevance of ECG findings 
using the central laboratory ECG interpretation report will be the responsibility of the 
Investigator and will be recorded in the patient’s eCRF.

Physical Examination
A complete physical examination will be performed at Visit 1 (Screening) and at Visit 8 
(Week 8/ET) by a professionally trained physician or health professional listed on Form 
FDA 1572 and licensed to perform physical examinations.
9.5.2.12.2
Columbia–Suicide Severity Rating Scale
The Columbia–Suicide Severity Rating Scale (C-SSRS) is an instrument that reports the 
severity of both suicidal ideation and behavior. Suicidal ideation is classified on a 5-item 
scale: 1 (wish to be dead), 2 (nonspecific active suicidal thoughts), 3 (active suicidal 
ideation with any methods [not plan] without intent to act), 4 (active suicidal ideation 
with some intent to act, without specific plan), and 5 (active suicidal ideation with 
specific plan and intent). The C-SSRS also captures information about the intensity of 
ideation, specifically the frequency, duration, controllability, deterrents, and reasons for 
the most severe types of ideation. Suicidal behavior is classified on a 5-item scale: 
0 (no suicidal behavior), 1 (preparatory acts or behavior), 2 (aborted attempt), 
3 (interrupted attempt), and 4 (actual attempt). More than 1 classification can be selected 
provided they represent separate episodes. For actual attempts only, the actual or 
potential lethality is classified for the initial, most lethal, and most recent attempts. 
The paper version of the C-SSRS will be completed at all study visits. At Visit 1
(Screening), the C-SSRS will be completed for the patient’s lifetime history of suicidal 
ideation and behavior (Appendix VIII). At all other visits, the C-SSRS will be completed 
for ideation and behavior since the previous visit (Appendix IX). The C-SSRS will be 
evaluated and signed at each visit by a qualified staff member (ie, the Investigator or 
designee that has extensive professional training and experience in assessing mental 
illness), before the patient leaves the study center.
The patient should not be released from the study center until the results of the C-SSRS 
are reviewed and the patient is not considered to be at risk. If there is doubt about 
whether a patient is at risk, the Investigator must obtain appropriate psychiatric 
consultation. The results of the C-SSRS will be recorded in the eCRF.

Investigational Product Concentration Measurements
PK blood samples will be collected from assented/consented patients aged 7-11 years to 
determine plasma concentrations of levomilnacipran. The blood sample will be 
processed, stored, and shipped as indicated in Appendix IV. The population PK of 
levomilnacipran will be characterized using serial and sparse plasma concentration-time 
data. The plasma concentration-time data collected will provide estimates of PK 
parameters, eg, area under the curve (AUC), half-life, maximum plasma drug 
concentration, and time of maximum plasma concentration.
Sparse PK blood samples will be collected during Visits 5, 6, and 7, as follows:
!
Visit 5, at predose and at 1-4 hour postdose
!
Visit 6, 4-6 hours postdose
!
Visit 7, 6-8 hours postdose
In case of scheduling constraints and with prior notification of AGN, the sampling times 
above may be collected in a different sequence among specified visits.
From a subset of consented patients instead of sparse PK samples, 7 serial PK blood 
samples will be collected at Visit 5 (or at any 24-hour period between Visit 5 and Visit 7, 
inclusive) at the following time points: predose (20-24 hours after the most recent dose), 
and 2, 4, 6, 8, 10-12, and 24-hours postdose.
To allow for a predose sampling, patients may be instructed to hold their daily dose on 
the sampling day and take it when instructed at the study center.
PK samples will not be obtained from patients who missed investigational product dosing 
for 2 or more consecutive days before the sampling date.
The actual date and clock times of the reference dose (the last dose taken before the PK 
sample) and all blood draws will be recorded in the eCRF along with the date and time of 
the 2 doses before the reference dose for each patient who undergoes PK sampling.

DATA QUALITY ASSURANCE
9.6.1
Data Monitoring
Before any patient enters the study, a representative of AGN will meet with the 
Investigator and the study center staff to review the procedures to be followed during the 
study. Electronic data capture (EDC) functionality training is provided via 
computer-based training to train Investigators and authorized designees on recording the 
data in the eCRFs using the EDC system. After the first patient is enrolled, the AGN
representative, a Regional Site Manager (RSM) or designee, will periodically monitor the 
progress of the study by conducting on-site visits. This RSM or designee will review 
query statuses remotely, possibly warranting more frequent communication and/or site 
visits with the Investigator and the study center staff. The Investigator will make 
available to the RSM or designee source documents (written notes and electronic medical 
records, if used), signed consent forms, and all other study-related documents. The 
Investigator and the study center staff will be responsible for data entry of patient data 
into the eCRFs via the EDC system, resolving data queries generated via the EDC 
system, and providing missing or corrected data. The Investigator or designee will be 
responsible for approving all changes performed on the data, and endorsing the patient 
data within the EDC system. This approval method will include applying an electronic 
signature linked to a uniquely assigned username and password that together will 
represent a traditional handwritten signature used in the past.

9.6.2
Data Recording and Documentation
Data collection will involve the use of the AGN EDC system, to which only authorized 
personnel will have access. Patient’s data are to be entered into the EDC system by the 
Investigator or designee using their assigned EDC user account. After data entry into the 
EDC system by the Investigator or designee, a combination of manual and programmatic 
edit checks will be used to review the data for completeness, logic, and adherence to 
study protocol. As a result of these edits checks, data monitoring, and reviews, queries 
may be electronically issued to the site and should be answered electronically via the 
EDC system.
Each query will carry identifying information (assigned username, date, and time) to 
assist AGN and the Investigator on the origin of the data clarification request and the 
response provided by the Investigator. All data changes made to the patient’s data via a 
data query will be approved by the Investigator before the final database lock.
After all data have been reviewed and all issues have been resolved, the database will be 
locked.
All data collected in the context of this study will be stored and evaluated per regulatory 
requirements and applicable guidance for electronic records. Also, data will be stored and 
evaluated in such a way as to guarantee patient confidentiality in accordance with the 
legal stipulations applying to confidentiality of data. Study records (eg, copies of eCRFs, 
laboratory reports, patient diaries, regulatory documents) will be retained at the site, 
along with adequate source documentation, according to FDA and ICH requirements. All 
study records must be available for inspection by AGN, its authorized representatives, 
and the FDA or other health authorities.

COVID-19 pandemic (ie, had protocol deviations, missing safety assessments, AEs 
[as determined by investigator], or withdrew from the study due to the COVID-19 
pandemic, or whose anxiety appeared to be affected by the pandemic) will also be 
summarized.
Screen failures (ie, patients who were screened but not included in the Randomized 
Population) and the associated reasons for failure will be tabulated overall. Patients 
completing 8 weeks of double-blind treatment (Visits 2-8) will be considered completers. 
The number and percentage of patients who complete the double-blind treatment period 
and of patients who prematurely discontinue during the same period will be presented for 
each treatment group and pooled across treatment groups. The reasons for premature 
discontinuation from the double-blind treatment period as recorded on the disposition
pages of the eCRF will be summarized (number and percentage) by treatment group for 
the safety population. 
The number and percentage of patients with important protocol deviations will be 
summarized overall and by treatment group for the Safety Population. Deviations related 
to the following categories will be included:

Concomitant medications
These and any additional important protocol deviations will be reviewed and documented 
before database lock and unblinding of treatment codes.
Protocol deviations that occur due to COVID-19 will be summarized and listed 
separately.

Demographics and Other Baseline Characteristics
Demographic parameters (eg, age, race, ethnicity, sex, weight, height, body mass index) 
and other baseline characteristics will be summarized by treatment group for the Safety 
and ITT populations. Descriptive statistics (n, mean, SD, minimum, median, and 
maximum) will be presented for continuous variables, and frequency distributions 
(counts and percentages) will be presented for categorical variables.
Prior medication is defined as any recorded medication taken before the date of the 
first dose of double-blind investigational product. Concomitant medication is defined as 
any recorded medication taken on or after the date of the first dose of double-blind 
investigational product. 
Both prior and concomitant medication use will be summarized by the number and 
proportion of patients in each treatment group receiving each medication within each 
therapeutic class for the Safety Population. Multiple medication use by a patient will only 
be counted once. Any recorded medications started after last dose of double-blind 
investigational product will not be summarized but will be included in listings.

Extent of Exposure 
9.7.4.1.1
Investigational Product
Exposure to double-blind investigational product for the Safety Population during the 
double-blind treatment period will be summarized for treatment duration, calculated as 
the number of days from the date of the first dose of double-blind investigational product 
taken to the date of the last dose taken, inclusive. Descriptive statistics (n, mean, SD, 
minimum, median, and maximum) will be presented by treatment group.
In addition, weekly and overall mean daily dose of investigational product will be 
summarized by treatment group for the Safety Population.

9.7.4.2
Measurement of Treatment Compliance 
Dosing compliance for a specified period will be defined as the total number of capsules 
actually taken by a patient during that period divided by the number of capsules 
prescribed to be taken for the same period multiplied by 100. This information will be 
obtained from the investigational product record of the patient’s eCRF. 
The total number of capsules actually taken during a specific time period is calculated 
based on the study medication record. The number of capsules prescribed to be taken for 
a specific treatment period will be calculated by multiplying the number of days in that 
period by the number of capsules to be taken per day.
Descriptive statistics for investigational product compliance will be presented by 
treatment group for each period between 2 consecutive visits, as well as for the entire 
double-blind treatment period.
9.7.5
Efficacy Analyses 
The efficacy analyses will be based on the ITT Population. Baseline for efficacy is 
defined as the last nonmissing efficacy assessment recorded at or prior to Visit 2. All 
statistical tests will be 2-sided hypothesis tests performed at the 5% level of significance. 
All confidence intervals will be 2-sided 95% confidence intervals, unless stated 
otherwise.
For efficacy analyses in which study center is a factor, a small center will be defined as a 
center with less than 2 patients in at least 1 treatment group in the ITT population. Small 
centers will be pooled to form pseudo centers so that each treatment group includes at 
least 2 ITT patients within the center. Pooling will be done using the following algorithm: 
Based on the number of ITT patients, small centers will be ordered from the largest to the 
smallest, and centers of the same size will be ordered from the largest center code to the 
smallest center code. The pooling process starts with the largest small center from the 
top, which will be pooled with the smallest from the bottom until a non-small center is 
formed. The process will be repeated using the small centers left out after the first pass. If 
any centers are left out at the end of the process, they will be pooled with the smallest 
pseudo center. If there is more than 1 smallest pseudo center, the pseudo center with the 
smallest center code will be selected. In case the pseudo center formed by pooling all 
small centers is still a small center, it will be pooled with the smallest non-small center. If 
there is more than 1 smallest non-small center, the one with the smallest center code will 
be selected.
By-visit analysis based on the mixed-effects model for repeated measures (MMRM) 
using the observed case approach will be performed for all continuous efficacy
parameters.
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC
Page 63
2020
In addition, by-visit analyses using the last-observation-carried-forward (LOCF) 
approach will be presented for all continuous efficacy parameters. For the LOCF 
approach, only the postbaseline total score of a parameter will be imputed using the 
LOCF approach; individual item scores will not be carried forward. Baseline total score 
will be carried forward only for the intermittent missing scores immediately after 
baseline. If all the postbaseline values are missing, the baseline value will not be carried 
forward.
9.7.5.1
Primary Efficacy Parameter
The primary efficacy parameter is the change from baseline to end of Week 8 in the 
CDRS-R total score. The primary analysis will be performed using an MMRM with 
treatment group, study center, visit, and treatment group–by-visit interaction as the fixed
effects and the baseline value and baseline value-by-visit interaction as the covariates. An 
unstructured covariance matrix will be used to model the covariance of within-patient 
scores. The Kenward-Roger approximation (Kenward and Roger, 1997) will be used to 
estimate denominator degrees of freedom. This analysis will be performed based on all 
postbaseline scores using only the observed cases without imputation of missing values. 
In the MMRM analysis, if the model fails to converge based on the unstructured 
covariance matrix, then structures of Heterogenous Toeplitz, Toeplitz, and Compound 
symmetry will be applied, only if necessary, in the specified order until the model 
converges.
In addition, 2 sensitivity analyses, LOCF and pattern-mixture model, will be performed 
on the primary efficacy parameter. For the LOCF approach, the between-treatment group 
comparison will be performed by means of an analysis-of-covariance model with 
treatment group and pooled study center as factors and the baseline CDRS-R total score 
as the covariate. The LOCF approach will be used to impute missing postbaseline values, 
provided that at least 1 postbaseline assessment is available. Missing values between the 
baseline and the first nonmissing postbaseline will be imputed with the baseline value. If
all the postbaseline values are missing, baseline value will not be carried forward. Only 
the total score of a parameter will be imputed using the LOCF approach; individual item 
scores will not be carried forward.
In the other sensitivity analysis, a pattern-mixture model based on non-future dependent 
missing value restrictions (Kenward 2003) will be performed to assess the robustness of 
the primary MMRM results to the possible violation of the missing-at–random 
missingness assumption. The non-future dependent missing value restriction states that 
the probability of drop-out at a specific visit can only depend on the observed value and 
the possibly missing value up to that visit, but not future values beyond that visit. The 
details of this sensitivity analyses are as follows:
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14
Allergan Sales, LLC
Page 64
2020
The pattern for the pattern-mixture model will be defined by the patient’s last visit with 
observed value. The observed CDRS-R total score at a visit is assumed to have a linear 
relationship with the patient’s prior measurements. The dataset with missing values will 
be imputed under the assumption that the distribution of a missing observation differs 
from the observed only by a shift parameter value Δ. The dataset with missing values will 
be analyzed using the same model as the primary analysis for between-treatment group 
comparisons at Week 8. The imputation of missing values and the analysis will be 
performed multiple times and the inference of this sensitivity analysis will be based on 
the combined estimates using the standard multiple imputation technique. The values for 
Δ will be selected as 0 to 6 based on experience with historical data. 
9.7.5.2
Secondary Efficacy Parameter
The secondary efficacy parameter is the change from baseline to the end of Week 8 in 
CGI-S score. This parameter will be analyzed similarly to the primary efficacy parameter.
A sensitivity analysis will also be performed using the LOCF approach as described in 
Section 9.7.5.1.
9.7.5.3
Additional Efficacy Parameters
The additional efficacy parameters will include the following at each postbaseline visit:
!
CGI-I score
!
Change from baseline in CGI-S score
!
CDRS-R response (≥ 40% reduction in CDRS-R from baseline) rate
!
CDRS-R remission (CDRS-R ≤ 28) rate
CGI-I score and the change in CGI-S will be analyzed using the MMRM and LOCF 
approaches similar to those used for the primary efficacy parameter. For CGI-I score, the 
baseline CGI-S score will be used as the baseline variable.
The CDRS-R response rate and CDRS-R remission rate will be analyzed using a 
generalized linear mixed model (GLMM), based on logit link function, with random 
intercept and flexible terms of treatment group, visit, treatment-by-visit interaction, and 
baseline score. If the GLMM does not converge, a logistic regression model with 
treatment group and the baseline score as explanatory variables will be used. For the 
logistic regression analysis, the postbaseline missing data will be imputed using the 
LOCF approach.

9.7.6
Safety Analyses
The safety analysis will be performed for the double-blind treatment period and 
double-blind down-taper period separately using the Safety Population. The safety 
parameters will include AEs, clinical laboratory parameters, vital sign measurements, 
ECG parameters, C-SSRS, and growth evaluations. For each safety parameter, the last 
assessment made before the first dose of double-blind investigational product will be 
used as the baseline for all analyses of that safety parameter. 
9.7.6.1
Adverse Events
An AE (classified by preferred term) that occurs during the double-blind treatment period 
or during the double-blind down-taper treatment period will be considered a 
treatment-emergent adverse event (TEAE) if it was not present before the date of the 
first dose of double-blind investigational product or was present before the date of the 
first dose of double-blind investigational product and increased in severity during the 
double-blind treatment period or during the double-blind down-taper period, respectively. 
If more than 1 AE is reported before the date of the first dose of double-blind 
investigational product and coded to the same preferred term, the AE with the greatest 
severity will be used as the benchmark for comparison with the AEs occurring during the 
double-blind treatment period or during the double-blind down-taper period that were 
also coded to that preferred term. An AE that occurs more than 30 days after the date of 
the last dose of double-blind investigational product will not be counted as a TEAE.
An AE occurring during the double-blind down-taper period will be considered a newly 
emergent AE if it was not present before the start of the double-blind down-taper period 
or was present before the start of the double-blind down-taper period but increased in 
severity during the double-blind down-taper period. The newly emergent AEs during the 
double-blind down-taper period will be summarized by body system, preferred term, and 
treatment group.
The number and percentage of patients reporting TEAEs in each treatment group will be 
tabulated by system organ class and preferred term; by system organ class, preferred 
term, and severity; and by system organ class, preferred term, and causal relationship to 
the investigational product. If more than 1 AE is coded to the same preferred term for the 
same patient, the patient will be counted only once for that preferred term using the most 
severe and most related occurrence for the summarization by severity and by causal
relationship to the investigational product.
The distribution of TEAEs by severity and causal relationship to the investigational 
product will be summarized by treatment group.

The incidence of common (≥ 2% of patients in any treatment group) TEAEs during the 
double-blind treatment period will be summarized separately by preferred term and 
treatment group and will be sorted by decreasing frequency for the test treatment. In 
addition, the incidence of fatal on-therapy SAEs (ie, events that caused death) will be 
summarized separately by treatment group and preferred term. An SAE will be defined as 
an on-therapy SAE if it occurred on or after the date of the first dose of double-blind 
investigational product and within 30 days of the date of the last dose of double-blind 
investigational product.
The incidence of SAEs and AEs leading to premature discontinuation of the study will 
also be summarized by study period, system organ class, preferred term, and treatment 
group.
Listings will be presented for SAEs, AEs leading to discontinuation, and death (if any).
9.7.6.2
Clinical Laboratory Parameters
Descriptive statistics for clinical laboratory values (in SI units) and changes from the 
baseline values at each assessment time point will be presented by treatment group for 
each clinical laboratory parameter.
The number and percentage of patients with potentially clinically significant (PCS) 
postbaseline clinical laboratory values will be tabulated by treatment group. The criteria 
for PCS laboratory values will be detailed in the Statistical Analysis Plan. The 
percentages will be calculated relative to the number of patients with available non-PCS 
baseline values and at least 1 postbaseline assessment. The numerator will be the total 
number of patients with available non-PCS baseline values and at least 1 PCS 
postbaseline value. A supportive listing of patients with PCS postbaseline values will be 
provided, including the PID number, study center number, and baseline and postbaseline 
values. 
9.7.6.3
Vital Signs
Descriptive statistics for vital signs (ie, pulse rate, systolic and diastolic BP, and body 
weight) and changes from baseline values at each visit and at end of study will be 
presented by treatment group. In addition, height and weight z-scores will be calculated 
based on growth charts (see Section 9.7.6.5.2).
Approval Date: 05-Aug-2020 10:42:17 (GMT)

Protocol LVM-MD-14

Vital sign values will be PCS if they meet both the observed-value criteria and the change 
from baseline–value criteria. The criteria for PCS vital sign values will be detailed in the 
Statistical Analysis Plan. The percentages will be calculated relative to the number of 
patients with baseline values and at least 1 postbaseline assessment. The numerator will 
be the total number of patients with available baseline values and at least 1 PCS 
postbaseline value. A supportive listing of patients with PCS postbaseline values will be 
provided, including the PID number, study center number, and baseline and postbaseline 
values. 
9.7.6.4
Electrocardiogram
Descriptive statistics for ECG parameters (ie, ventricular heart rate, RR interval, 
PR interval, QRS interval, QT interval, and QTc interval) and changes from baseline 
values at each assessment time point will be presented by treatment group. The QTc 
interval is calculated using the Bazett and Frederica corrections.
The number and percentage of patients with PCS postbaseline ECG values will be 
tabulated by treatment group. The criteria for PCS ECG values will be detailed in the 
Statistical Analysis Plan. The percentages will be calculated relative to the number of 
patients with available non-PCS baseline values and at least 1 postbaseline assessment. 
The numerator will be the total number of patients with available non-PCS baseline 
values and at least 1 PCS postbaseline value. A supportive listing of patients with 
PCS postbaseline values will be provided, including the PID number, study center 
number, and baseline and postbaseline values. 
A listing of patients with postbaseline clinically significant ECG abnormalities, as 
reported by the Investigator or by the central cardiologist, will also be provided.
The number and percentage of patients with an increase > 30 msec but ≤ 60 msec, and 
with an increase > 60 msec in QTcF will be tabulated. A supportive listing of patients 
with postbaseline QTcF increases > 30 msec will be provided, including the PID number, 
study center, and all QTcF values (including changes from baseline). A listing of all AEs 
for patients with postbaseline QTcF increases > 30 msec will also be provided.

Other Safety Parameters
9.7.6.5.1
Columbia-Suicide Severity Rating Scale
For the C-SSRS, the number and percentage of patients with suicidal ideation or suicidal 
behavior as recorded on the C-SSRS scale will be presented by treatment group. The 
distribution of responses for most severe suicidal ideation and suicidal behavior during 
the lifetime history, the double-blind treatment period and the down-taper period will also 
be presented by treatment group for the Safety Population. Supportive listings will be 
provided and will include the PID number, treatment group, visit number, lifetime 
history, and postbaseline values for each patient. Intensity of ideation, suicidal behavior 
type, and lethality of suicidal behavior will also be included in these listings.
9.7.6.5.2
Growth Evaluation
Weight and height will be presented as standardized z-scores adjusted for gender and age, 
using the lambda-mu-sigma method (Cole TJ 1990). To assess the impact of treatment on 
growth, the change from baseline in the age and gender adjusted height will be analyzed 
using an analysis of variance model with treatment as factor. A non-parametric 
(Wilcoxon) test will also be performed.
9.7.6.6
Investigational Product Plasma Concentration Parameters
Plasma samples will be analyzed for the concentrations of levomilnacipran using 
validated bioanalytical methods. Population PK parameters will be estimated using 
nonlinear mixed-effects modeling methods. The study will be prospectively powered to 
target a 95% confidence interval within 60% and 140% of the geometric mean estimates 
of clearance and volume of distribution for levomilnacipran ER, with at least 80% power.
9.7.7
Health Economics and Outcomes Research Analyses
Not applicable.
9.7.8
Interim Analysis
The interim analysis was conducted to identify early signs of futility after 62% of 
randomized patients had either completed or discontinued the study. The futility 
assessment of the primary efficacy parameter (CDRS-R total score) on ITT population 
was based on the conditional power as described in Lan et al. 1999. In calculating the 
conditional power, it was assumed that the future patients to be enrolled into the Study
will have similar efficacy as those of the existing patients of the same treatment group. 
The non-binding futility criteria was set when the conditional power for detecting a 
statistically significant treatment difference between the levomilnacipran treatment group 

Protocol LVM-MD-14
Allergan Sales, LLC
Page 69
2020
(40-80 mg/day) and placebo at the final analysis was 0.2 (20%) or lower given the 
interim analysis results. After the futility analysis results were reviewed by a data 
monitoring committee member, it was determined that this study will continue until the 
planned study end.
9.7.9
Determination of Sample Size
The effect size (treatment group difference relative to pooled SD) of 0.36 for both 
levomilnacipran and fluoxetine is based on a treatment difference of 4 units with a 
common pooled SD of 11.1 for the primary efficacy parameter, change from baseline to 
Week 8 in CDRS-R total score. A sample size of 480 patients (160 per treatment group) 
will be needed to provide 85% power for primary analysis (levomilnacipran vs placebo) 
based on an MMRM model using simulation method (Lu 2012). The simulation assumed 
a correlation of 0.7 between the repeated measures and a dropout rate of 17% based on 
historical data in pediatric patients.

PHARMACOKINETIC BLOOD SAMPLING AND 
SHIPPING INSTRUCTIONS (ONLY IN PARTICIPANTS 
AGED 7-11 YEARS)
Specimen Tube Collection Preparation
!
Adhere the provided label to a 3-mLVacutainer K2EDTA containing tube 
!
Prechill (eg, in an ice bath or refrigerator) the labeled Vacutainer tube and a 
polypropylene tube 
Plasma Collection Procedure
!
Collect blood into the prechilled Vacutainer tube; invert the tube gently 8-10 times to 
mix the blood and anticoagulant. Place the tube in an ice-water bath (use crushed ice).
!
Centrifuge the tube (within 30 minutes from the time the blood is drawn) at 2500 rpm 
to 3750 rpm for 10 minutes at approximately 4°C (ie, refrigerated centrifuge). In 
absence of a refrigerated centrifuge, the blood tubes should be chilled in ice for at 
least 10 minutes prior to centrifuging. Blood samples should still be centrifuged 
within 30 minutes of blood collection.
!
After centrifugation, transfer harvested plasma immediately into a prechilled, labeled, 
polypropylene tube provided by the central laboratory. Ensure the tube has the 
appropriate label marked with study number, patient identification number, date, and 
time of collection. 
!
The tube must then be immediately placed in the freezer and should be stored at 
approximately –70°C (or up to 6 weeks at –20°C).
!
Enter the actual time that the blood sample was collected on the appropriate form of 
the eCRF.
!
Send the frozen sample to the central laboratory according to the central laboratory 
sample shipment guide.
Shipping Guide from the Study Center to the Central Laboratory
Samples will be shipped from the study center to the central laboratory on the 
first available appropriate date after sample collection, and can be batch-shipped but no 
later than 6 weeks after sample collection. The central laboratory will provide packaging, 
labeling, and shipping instructions to the study center. Plasma samples will be shipped on 
sufficient dry ice to keep them frozen for at least 96 hours.
