SUMMARY 
EP0065 is a Phase 2, multicenter, open-label study with a primary objective of evaluating the 
pharmacokinetics (PK), safety, and tolerability of brivaracetam (BRV) administered as a 
15-minute intravenous (iv) infusion and an iv bolus (up to 2-minute infusion) in subjects 
≥1 month to <16 years of age with epilepsy. 
The following subjects will be eligible for enrollment in EP0065: 
 Open-label BRV (OLB) subjects: currently receiving oral BRV as participants in a 
long-term, open-label study 
 Prescribed-BRV (RxB) subjects: currently receiving prescribed oral BRV from commercial 
supply 
 Initiating Oral BRV (IOB) subjects: not currently receiving BRV; first dose of BRV in 
EP0065 will be oral tablet or solution 
 Initiating iv BRV (IIB) subjects: not currently receiving BRV; first dose of BRV in EP0065 
will be administered intravenously 
EP0065 includes the following consecutive periods:

BRV=brivaracetam; IIB=Initiating iv BRV; IOB=Initiating Oral BRV; iv=intravenous; 
OLB=Open-label BRV; PK=pharmacokinetic RxB=Prescribed-BRV 
Note: Oral BRV will be administered as tablets or oral solution. Tablets will be administered 
orally, and oral solution will be administered either orally or by enteric administration (eg, 
feeding tube) based on subject need. 
During the Screening Period, OLB and RxB subjects will continue to receive oral BRV (tablet or 
oral solution) in accordance with their long-term, open-label study dosing or prescribed dosing, 
respectively. The IOB and IIB subjects will not receive BRV during the Screening Period. 
Eligible OLB, RxB, and IIB subjects will progress directly from the Screening Period to the 
iv PK Period, whereas IOB subjects will enter a 2- to 10-day IOB Treatment Period in which 
they receive oral BRV before progressing to the iv PK Period. The initial oral BRV dose in the 
IOB Treatment Period is 2mg/kg/day. 
During the iv PK Period, iv BRV will be administered every 12 hours ±2 hours (q12h ± 2h). All 
subjects will receive 1 to 2 consecutive doses of BRV; however, based on medical need, subjects 
may receive up to 10 consecutive doses of iv BRV. Blood sampling for PK analyses (herein 
referred to as “PK sampling”) will occur with the first iv BRV administration and with 1 other iv 
BRV administration. For OLB, RxB, and IOB subjects, the first iv BRV dose will be equivalent

(mg-to-mg) to the final dose of oral BRV prior to the first iv dose. For IIB subjects, the first iv 
BRV dose will be 1mg/kg, not to exceed 50mg for subjects with body weights ≥50kg. For all 
subjects, iv BRV doses may be adjusted at the Investigator’s discretion after PK sampling for 
2 iv doses; however, no doses may exceed the maximum doses indicated below. During the 
iv PK Period, BRV may only be administered by iv infusion.  
At the completion of the iv PK Period, subjects who will continue oral BRV treatment should 
enroll in a long-term, open-label BRV study. Subjects who have received ≥4 doses of BRV and 
do not plan to continue treatment with BRV after completion of the iv PK Period or who 
discontinue BRV treatment during the study will have a Down-Titration Period of up to 4 weeks 
(28 days) for gradual discontinuation of BRV and a Safety (BRV-free) Period of 2 weeks 
(14 days) after the final dose of BRV. Subjects who have received <4 doses of BRV may have 
BRV down titrated at the discretion of the Investigator. 
For IOB and IIB subjects, the maximum BRV dose is 4mg/kg/day (2mg/kg twice daily [bid]). 
For OLB and RxB subjects, the maximum BRV dose is 5mg/kg/day (rounded) in recognition of 
the possibility that some of these subjects may be using this dose when they enter EP0065. 
Throughout the study, no subjects may receive a dose greater than BRV 200mg/day. Oral 
BRV will be administered in equally divided doses bid.  
It is planned for approximately 50 enrolled subjects to receive iv BRV in the following 
age-based cohorts (approximately 12 subjects/cohort), with approximately half of the subjects in 
each cohort receiving iv BRV as a 15-minute (±3 minutes) infusion and half receiving iv BRV as 
a bolus (up to 2-minute infusion). 
 Cohort 1: ≥12 to <16 years  
 Cohort 2: ≥6 years to <12 years  
 Cohort 3: ≥2 to <6 years  
 Cohort 4: 1 month to <2 years  
Enrollment will be sequential by descending age beginning with Cohort 1. For each cohort, the 
first half will receive the 15-minute infusion. The Data Monitoring Committee (DMC) will then 
meet to review safety and PK data, as available. After the DMC safety review, the remaining half 
in that cohort will receive iv BRV as a bolus (up to 2-minute infusion), and the next cohort may 
begin the 15-minute infusion. Subjects may receive bolus infusions only after subjects in the 
preceding cohort have completed bolus infusions. 
The DMC will meet no less than approximately every 6 months commensurate with enrollment.  
The PK variables are the plasma concentrations of BRV (parent compound only) before, during, 
and after the first and 1 subsequent administration of iv BRV.  
The primary safety variables are adverse events (AEs) and withdrawals due to AEs. Other safety 
variables are clinical laboratory parameters (hematology, chemistry, and endocrinology), and 
urinalysis. Clinically significant new or worsened abnormalities discovered during physical and 
neurological examinations will be recorded as AEs. Other safety variables also include 12-lead 
electrocardiogram (ECG), and vital signs (blood pressure [BP], pulse rate, respiratory rate [RR],

and temperature), all of which will be assessed with increased frequency during the iv PK 
Period.  
The maximum study duration for an individual subject will be 68 days. Approximately 60 sites 
in Europe and North America are planned for participation in EP0065.

INTRODUCTION 
Brivaracetam ((2S)-2-[(4R)-2-oxo-4-propyltetrahydro-1H-pyrrol-1-yl]butanamide) displays a 
high and selective affinity for the synaptic vesicle protein 2A (SV2A) in the brain. Binding to 
SV2A is believed to be the primary mechanism for BRV anticonvulsant activity. In 2016, 
marketing authorization for the use of oral and iv BRV as adjunctive treatment of partial-onset 
seizures (POS) in patients was granted in the EU, US, and Australia for patients 16 years of age 
and older with epilepsy and in Canada for patients 18 years of age and older with epilepsy. 
Epilepsy affects all races of both sexes at any age from the first hour of life to extreme old age. 
The prevalence of epilepsy is 1% to 2% of the population and 4% of pediatric population in 
those developed countries where they have been studied; this is probably double in resource-poor 
countries (Banerjee and Hauser, 2008). In the US, the overall incidence of epilepsy ranges from 
35.5 to 48 per 100,000 person-years and the prevalence ranges from 4.7 to 6.8 per 1000 
population (Theodore et al, 2006). The incidence of new-onset epilepsy in the pediatric 
population is 44.5 per 100,000 persons per year (Wirrell et al, 2011). Within the pediatric 
population, the incidence is highest in children <5 years of age (approximately 60 to 100 per 
100,000 person-years), decreasing to approximately 25 to 45 per 100,000 person-years in 
adolescents and young adults (Wirrell et al, 2011; Hauser et al, 1993).  
In the US, 57% of newly diagnosed patients were classified as having POS (Zarrelli et al, 1999; 
Hauser et al, 1993). In the general population, the incidence of pediatric patients with epilepsy 
with POS is approximately 16 to 80 per 100,000 (Wirrell, et al, 2011; Banerjee and Hauser, 
2008; Hauser et al, 1993).  
The existing treatment options for POS in the pediatric population generally follow the treatment 
options for adults with the same disorder; clinical experience demonstrates that children may 
have results comparable to adults with administration of the conventional antiepileptic drugs 
(AEDs). More than 25% of pediatric patients have inadequate seizure control on currently 
available AEDs or experience significant adverse drug effects (Hadjiloizou and Bourgeois, 
2007). There remains a need for potent AEDs with a positive benefit-risk profile in this 
population.  
To date, oral formulations of BRV have been studied in the ongoing BRV pediatric development 
program as follows:  
N01263 is a completed open-label, multicenter, fixed 3-step up-titration, adjunctive therapy 
study of the PK, safety, and efficacy of BRV in 100 subjects ≥1 month to <16 years of age 
with epilepsy. Doses of BRV (oral solution) were adjusted by body weight and did not 
exceed a maximum of 50mg/day, 100mg/day, and 200mg/day for each titration step. A total 
of 100 subjects enrolled in N01263: 99 subjects received study drug and were included in the 
Safety Set. Results from N01263 indicate that BRV was generally well tolerated and that the 
safety profile in pediatric subjects was consistent with the known safety profile in adult

subjects. In general, there were no clinically meaningful changes in laboratory parameters, 
vital signs, or ECG parameters. Trough plasma BRV concentrations increased proportionally 
to the dose.  
N01266 is an ongoing open-label, multicenter study to evaluate the long-term safety and 
efficacy of bid administration of BRV oral solution and oral tablets in pediatric subjects with 
epilepsy who are receiving ≥ 1 AED other than BRV; the maximum allowable BRV dose is 
5mg/kg/day not to exceed 200mg/day in subjects with body weights >40kg. N01266 was 
initially designed as a long-term follow-up to N01263, which enrolled only subjects with 
either focal epilepsy or generalized epilepsy but was amended to also allow direct enrollment 
of subjects 4 years to <17 years of age who have focal epilepsy. Over 200 subjects have 
enrolled in N01266. 
In addition to oral formulations, iv formulations of AEDs are particularly helpful as short-term 
replacements when use of oral formulations is not possible or feasible (eg, pre and postoperative 
patients, patients with acute gastrointestinal disorders, patients with acute swallowing disorders). 
Brivaractem injection has been approved for use as adjunctive therapy in the treatment of POS in 
patients 16 years of age and older with epilepsy and may be used when oral administration of 
BRV is temporarily not feasible. Treatment with BRV may be initiated with tablets, oral 
solution, or solution for injection. 
The current study, EP0065, is planned to evaluate the PK, safety, and tolerability of iv BRV 
administered as a 15-minute infusion and bolus (up to 2-minute infusion) in subjects ≥1 month to 
<16 years of age with epilepsy.  
The iv dose for subjects initiating BRV in this study was predicted in N01331, which modeled 
based on PK data from N01263 and N01256 (BRV adult study) and simulated the BRV iv 
concentrations in pediatric subjects. Based on the results of N01331, in the pediatric population 
1 month to <17 years of age, an iv injection 15-minute infusion or bolus (up to 2-minute 
infusion) of 4mg/kg/day (2mg/kg bid) regimen (with a maximum of 200mg/day [100mg bid] for 
subjects with body weights ≥50kg) results in plasma concentrations in the same range as seen in 
adults receiving 200mg/day (100mg bid), the maximum recommended dose in adults with POS. 
These data support using a mg-to-mg equivalent to the oral dose for OLB and RxB subjects. As 
demonstrated in the concentration-effect analysis CL0258 using levetiracetam PK and 
pharmacodynamic (PD) data from adults and children and BRV PK and PD data in adults 
(N01358) and PK data in children (N01263), in subjects 4 to 16 years of age, similar 
weight-normalized doses are needed to achieve the same efficacy as compared with adults, with 
a maximum response at 4mg/kg/day. 
More detailed information regarding the nonclinical and clinical development programs for BRV 
is provided in the Investigator’s Brochure.

STUDY DESIGN 
5.1 
Study description 
EP0065 is a Phase 2 multicenter, open-label study to evaluate the PK, safety, and tolerability of 
iv BRV administered as a 15-minute iv infusion and an iv bolus (up to 2-minute infusion) in 
subjects ≥1 month to <16 years of age with epilepsy.  
It is planned for approximately 50 enrolled subjects to receive iv BRV in the following 
age-based cohorts (approximately 12 subjects/cohort): 
 Cohort 1: ≥12 to <16 years  
 Cohort 2: ≥6 years to <12 years  
 Cohort 3: ≥2 to <6 years  
 Cohort 4: 1 month to <2 years  
The following subjects will be eligible for enrollment in EP0065: 
 OLB subjects: currently receiving oral BRV as participants in a long-term, open-label study 
 RxB subjects: currently receiving prescribed oral BRV from commercial supply 
 IOB subjects: not currently receiving BRV; first dose of BRV in EP0065 will be oral tablet 
or solution 
 IIB subjects: not currently receiving BRV; first dose of BRV in EP0065 will be by iv 
infusion

For OLB and RxB subjects, the maximum BRV dose is 5mg/kg/day (rounded). For IOB and IIB 
subjects, the maximum BRV dose is 4mg/kg/day. Throughout the study, no subject may 
receive a dose greater than BRV 200mg/day. Subjects will receive oral BRV (tablets or oral 
solution) in equally divided doses; BRV oral solution may be given by enteric administration 
(eg, by feeding tube) based on subject need. 
The EP0065 study periods and visits are described below. The PK assessments will be made 
during the iv PK Period only and safety data will be collected throughout the study, with 
intensive collection of safety data with each iv BRV dose administered. A Schedule of Study 
Assessments is provided for the Screening through iv PK Periods in Table 5‒1 and for the 
Down-Titration Period and Safety (BRV-free) Periods (for subjects not continuing BRV) in 
Table 5‒4. 
Screening Period (1 to 10 days) 
During the Screening Period, the OLB and RxB subjects will continue treatment with oral BRV 
using their assigned open-label study supply or prescribed commercial supply, respectively. The 
IOB and IIB subjects will not receive BRV during this period.  
The OLB subjects will temporarily discontinue assessments in their long-term, open-label study 
when they enter EP0065. As such, all assessments for these subjects during the Screening Period 
(and subsequent periods of EP0065) will be recorded in the EP0065 Case Report form (CRF) 
until they return to a long-term, open-label study or discontinue BRV treatment. 
IOB Treatment Period (2 to 10 days of oral BRV treatment; for IOB subjects only) 
Only IOB subjects who meet all eligibility criteria may participate in the IOB Treatment Period. 
No other subjects may participate in this period. 
During the IOB Treatment Period, IOB subjects will initiate treatment with oral BRV 
2mg/kg/day not to exceed 100mg/day for subjects with body weights ≥50kg and must have, at 
minimum, 2 days of treatment with oral BRV before entry into the iv PK Period. Subjects who 
do not enter the iv PK Period will not be eligible for the long-term, open-label study. 
The Investigator is permitted to adjust the oral BRV dose during the IOB Treatment Period in 
accordance with medical judgment (with a maximum dose of 4mg/kg/day, not to exceed 
200mg/day for subjects with body weights ≥50kg); however, subjects must have no change in 
the oral BRV dose for the 2 days prior to entry into the iv PK Period.  
iv PK Period (1 to 6 days, with Day 1 defined as the initial day of iv BRV infusion) 
During the iv PK Period, iv BRV will be administered every 12 hours ±2 hours (q12h ± 2h). All 
subjects are to receive 1 to 2 consecutive doses of BRV; however, based on medical need, 
subjects may receive up to 10 consecutive doses of iv BRV. The PK sampling will occur with the 
first iv BRV administration and with 1 other iv BRV administration.  
The first dose of iv BRV will be as follows: 
 OLB, RxB, and IOB subjects: mg-to-mg equivalent of the oral BRV dose immediately prior 
to the iv PK Period; administered q12h ±2h after prior oral dose 
 IIB subjects: 1mg/kg not to exceed a maximum of 50mg for subjects ≥50kg

After subjects have completed PK sampling with 2 iv BRV infusions, the Investigator may adjust 
the BRV dose, but the adjusted dose must not exceed 5mg/kg/day (rounded) for OLB and RxB 
subjects and 4mg/kg/day for IOB and IIB subjects (with the maximums not to exceed 
200mg/day). During the iv PK Period, BRV may only be administered intravenously. Enrollment 
will be sequential by descending age beginning with Cohort 1. For each cohort, the first half will 
receive the 15-minute infusion. The Data Monitoring Committee (DMC) will then meet to 
review safety and, as available, PK data (Figure 5‒1). After the DMC safety review, the 
remaining half in that cohort will receive iv BRV as a bolus (up to 2-minute infusion) and the 
next cohort may begin the 15-minute infusion. Subjects may receive bolus infusions only after 
subjects in the preceding cohort have completed bolus infusions and the DMC have reviewed 
these data. The DMC will meet no less than approximately every 6 months commensurate with 
enrollment.

The schedules for PK sampling, 12-lead ECGs, and vital sign assessments during the iv PK 
Period are provided in Table 5‒2 (15-minute infusion), and Table 5‒3 (bolus [up to 2-minute 
infusion]). 
Down-Titration Period (up to 4 weeks) and Safety (BRV-free) Period (2 weeks) 
Subjects who receive ≥4 doses of BRV during either the IOB Treatment Period or the iv PK 
Period and who do not plan to continue treatment with BRV or who discontinue from the study 
will enter a Down-Titration Period. Subjects who have received <4 doses of BRV may have 
BRV down titrated at the discretion of the Investigator. During the Down-Titration Period, 
subjects will have their BRV dose reduced by a maximum of half the dose every week for a 
maximum of 4 weeks until a dose of 1mg/kg/day (50mg/day for subjects with body weights 
≥50kg) is reached. Subjects not able to receive oral BRV for down titration, may receive iv BRV 
for down titration. In the latter circumstance, the subjects may receive more than 10 consecutive

doses of iv BRV in accordance with the Investigator’s discretion. A 2-week Safety (BRV-free) 
Period will follow the final dose of BRV.  
Safety assessments will be collected throughout this period (Table 5‒4). 
5.1.1 
Study duration per subject and definition for start/end of study 
The maximum possible study duration is 68 days and the maximum period of BRV 
administration is 44 days including a minimum of 1 dose of iv BRV.

executed. The end of the study is defined as the date of the last visit of the last subject enrolled. 
5.1.2 
Planned number of subjects and sites 
It is planned for approximately 50 enrolled subjects to receive iv BRV. Approximately 60 sites 
are planned. 
5.1.3 
Anticipated regions and countries 
Approximately 60 sites in Europe and North America are planned for participation in EP0065.  
5.2 
Schedule of study assessments 
A schedule of study assessments for the Screening Period through the iv PK Period is provided 
in Table 5‒1, with detailed schedules for PK sampling, ECG, and vital sign assessments during 
the iv PK Period provided in Table 5‒2 (15-min infusion) and Table 5‒3 (bolus [up to 2-minute 
infusion]).  
A schedule of study assessment for subjects who will not continue BRV is provided in Table 5‒4 
(Down-Titration and Safety [BRV-free] Periods).  
Note, possibly clinically significant (PCS) vital sign values are defined as those PCS values 
which occur at any time during the study. Only BP to be collected at 2 hours post initiation of 
infusion. Additional vital sign monitoring, specifically BP is necessary if a low PCS BP value 
occurs at 2 hours after the start of an infusion. Subjects should not be provided iv BRV if the 
latest <1-hour pre-initiation measurement of systolic or diastolic BP is a low PCS value. In this 
case BP measurements should be repeated and the iv BRV infusion be started only after the BP 
does not meet the low PCS criterion anymore. The criteria for BP values to be low or high PCS 
values are described in Table 10-6.

Rationale for study design and selection of dose 
In 2016, marketing authorization for the use of oral and iv BRV as adjunctive therapy in the 
treatment of POS was granted in the in the EU, US, and Australia for patients 16 years of age 
and older and in Canada for patients 18 years of age and older with epilepsy. The recommended 
starting dosing of BRV is 50mg bid. Based on individual patient tolerability and therapeutic 
response, the dosage may be adjusted down to 25mg bid (50mg/day) or up to 100mg bid 
(200mg/day). Brivaracetam injection can be administered intravenously over 2 to 15 minutes 
when oral administration of BRV is temporarily not feasible. Pharmacokinetic data for BRV 
administered by the oral route are available over the age range from adults down to 1 month of 
age and have demonstrated that BRV is completely absorbed and fully bioavailable orally. In 
adults, BRV iv bolus and oral tablet are bioequivalent.  
Brivaracetam injection was evaluated in N01258, an open-label, multicenter study evaluating the 
safety and tolerability of BRV 200mg/day administered for 4.5 days as a 15-minute iv infusion 
or a 2-minute iv bolus in subjects ≥16 to 70 years of age with epilepsy. Results from N01258 
indicated that iv BRV (as both 15-minute infusion and 2-minute bolus) was well tolerated. The 
AE profile was similar regardless of whether iv BRV was administered as a 2-minute bolus or a 
15-minute infusion. Given these results in older subjects ≥16 years, it is expected that BRV will 
have similar results in younger subjects aged ≥1 month to <16 years of age. 
The PK, safety, and efficacy of BRV in 100 subjects aged ≥1 month to <16 years with epilepsy 
were evaluated in N01263, an open-label, multicenter, fixed 3-step up-titration, adjunctive 
therapy study using an oral solution formulation. All doses were adjusted by body weight and did 
not exceed a maximum of 50mg/day, 100mg/day, and 200mg/day for each titration step. Results 
from N01263 indicated that BRV was generally well tolerated and that the safety profile in 
subjects aged ≥1 month to <16 years was consistent with the known safety profile in adults. 
Trough plasma BRV concentration increased proportionally to BRV dose. 
The iv dose for subjects initiating BRV in this study was predicted in N01331, which modeled 
based on PK data from N01263 and N01256 (BRV adult study) and simulated the BRV iv 
concentrations in pediatric subjects. Based on the results of N01331, in the pediatric population 
1 month to <17 years of age, an iv injection 15-minute infusion or bolus (up to 2-minute 
infusion) of 4mg/kg/day (2mg/kg bid) regimen with a maximum of 200mg/day (100mg bid) 
results in plasma concentrations in the same range as seen in adults receiving 200mg/day (100mg 
bid), the maximum recommended dose in adults with POS. These data support using a mg-to-mg 
equivalent to the oral dose for OLB and RxB subjects. As demonstrated in the 
concentration-effect analysis CL0258 using levetiracetam PK and PD data from adults and 
children and BRV PK and PD data in adults (N01358) and PK data in children (N01263), in 
subjects 4 to 16 years of age, similar weight-normalized doses are needed to achieve the same 
efficacy as compared with adults, with a maximum response at 4mg/kg/day. 
EP0065 has been designed to evaluate the PK, safety, and tolerability of iv dosing of BRV in 
subjects 1 month to <16 years of age, as iv formulations are particularly helpful as short-term 
replacement of oral formulations for patients unable to take oral products (eg, pre and 
postoperative patients, patients with acute gastrointestinal disorders). For OLB and RxB subjects, 
the maximum BRV dose is 5mg/kg/day (rounded) to allow for the possibility that these subjects 
enter EP0065 on this dose. Dose selection for IOB and IIB subjects was based on the results 
obtained in N01331 and the recommended dose of BRV as adjunctive therapy in the treatment of

POS in patients 16 years of age and older with epilepsy. For IOB and IIB subjects, the starting 
BRV dose (2mg/kg/day [1mg/kg bid]) and maximum BRV dose (4mg/kg/day [2mg/kg bid]) in 
subjects with body weights <50kg approximate the 100mg/day (50mg bid) starting dose and 
200mg/day (100mg bid) maximum dose recommended for use in adults. No subjects enrolled in 
EP0065 are permitted have a dose that exceeds a maximum of 200mg/day (100mg bid) as 
consistent with the maximum recommended dose.

14. Subject has >1.5x upper limit of normal (ULN) of any of the following: alanine 
aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or 
>ULN total bilirubin (≥1.5xULN total bilirubin if known Gilbert’s syndrome). If subject has 
elevations only in total bilirubin that are >ULN and <1.5xULN, fractionate bilirubin to 
identify possible undiagnosed Gilbert’s syndrome (ie, direct bilirubin <35%). 
For randomized subjects with a baseline result >ULN for ALT, AST, ALP, or total bilirubin, 
a baseline diagnosis and/or the cause of any clinically meaningful elevation must be 
understood and recorded in the CRF. 
If subject has >ULN ALT, AST, or ALP that does not meet the exclusion limit at Screening, 
repeat the tests, if possible, prior to dosing to ensure there is no further ongoing clinically 
relevant increase. In case of a clinically relevant increase, inclusion of the subject must be 
discussed with the Medical Monitor. 
Tests that result in ALT, AST, or ALP up to 25% above the exclusion limit may be repeated 
once for confirmation. This includes re-screening.  
15. Subject has chronic liver disease.

10. Subject and/or delegated caregiver is noncompliant with study procedures or medication, in 
the opinion of the Investigator. 
11. For subjects ≥6 years of age, subject has active suicidal ideation without a specific plan as 
indicated by a positive response (“Yes”) to Question 4 of the “Since Last Visit” version of C-
SSRS. The subject should be referred immediately to a Mental Healthcare Professional and 
may be withdrawn from the study based upon the Investigator’s judgment of benefit/risk of 
continuing the subject in the study/on study medication. 
 Investigators should attempt to obtain information on subjects in the case of withdrawal; 
subjects who withdraw from the study without down titration of BRV should complete the 
Visit 13 (Table 5‒4). 
For subjects considered lost to follow up, the Investigator should make an effort (at least 1 phone 
call and 1 written message to the subject), and document his/her effort (date and summary of the 
phone call and copy of the written message in the source documents), to complete the final 
evaluation. All results of these evaluations and observations, together with a narrative description 
of the reason(s) for removing the subject, must be recorded in the source documents. The CRF 
must document the primary reason for withdrawal. 
Investigators should contact the Medical Monitor, whenever possible, to discuss the withdrawal 
of a subject in advance. 
6.3.1 
Potential drug-induced liver injury investigational medicinal product 
discontinuation criteria 
Subjects with potential drug-induced liver injury (PDILI) must be assessed to determine if the 
investigational medicinal product (IMP) must be discontinued. In addition, all concomitant 
medications and herbal supplements that are not medically necessary should also be 
discontinued.  
The PDILI criteria below require immediate and permanent discontinuation of IMP:  
 Subjects with either of the following: 
 ALT or AST ≥5xULN 
 ALT or AST ≥3xULN and coexisting total bilirubin ≥2xULN  
The PDILI criterion below requires immediate discontinuation of IMP: 
 Subjects with ALT or AST ≥3xULN who exhibit temporally associated symptoms of 
hepatitis or hypersensitivity. Hepatitis symptoms include fatigue, nausea, vomiting, right 
upper quadrant pain or tenderness. Hypersensitivity symptoms include fever (without clear 
alternative cause), rash, or eosinophilia (ie, >5%). 
The PDILI criterion below allows for subjects to continue on IMP at the discretion of the 
Investigator.  
 Subjects with ALT or AST ≥3xULN (and ≥2x baseline) and <5xULN, total bilirubin 
<2xULN, and no eosinophilia (ie, ≤5%), with no fever, rash, or symptoms of hepatitis (eg, 
fatigue, nausea, vomiting, right upper quadrant pain or tenderness).

Treatments to be administered 
For BRV tablets, the mg dosage for the oral tablet treatment should be calculated to match as 
closely as possible the mg/kg based dosage. Tablets of BRV 10mg, 25mg, 50mg, 75mg, and 
100mg are supplied and may be combined, as needed, to achieve the calculated mg/kg dose. 
Tablets and solution must not be used together to comprise an individual dose. 
The dose of oral solution will be measured using the appropriate syringes (1mL, 3mL, and/or 
10mL) with an adaptor able to fit the bottle sizes. Oral solution should not be mixed with other 
liquids prior to administration.  
For 15-min iv infusions, a calibrated infusion pump should be used for delivering the iv BRV 
dose at a constant rate over the target duration assigned. A previously unused vial must be 
administered for each dose. Dilution is not required prior to administration of iv BRV. The BRV 
solution for iv injection can be diluted as needed in any of the following diluents:  
 0.9% sodium chloride injection  
 Lactated Ringer’s injection  
 5% dextrose injection  
The total volume of diluent should be calculated not to exceed a total volume of fluid intake/day 
based on the Holliday-Segar equation as follows:  
 For children weighing ≤10kg: 100mL/kg body weight 
 For children weighing >10 to ≤20kg: 1000mL + 50mL/kg for each kg body weight ≥10kg

subjects with body weights ≥50kg) is reached. Subjects who have received <4 doses of BRV 
may have BRV down titrated at the discretion of the Investigator. Subjects not able to receive 
oral BRV for down titration, may receive iv BRV for down titration. In the later circumstance, 
the subjects may receive more than 10 consecutive doses of iv BRV in accordance with the 
Investigator’s discretion. 
The OLB subjects who discontinue BRV during the Screening Period will return to the 
long-term, open-label study for down titration of BRV.

Handling and storage requirements 
The Investigator (or designee) is responsible for the safe and proper storage of IMP at the site. 
Investigational medicinal product stored by the Investigator is to be kept in a secured area with 
limited access according to the storage conditions mentioned on the label. Additional 
information pertaining to the handling of BRV, a Schedule V drug, is provided in the IMP 
Handling Manual. 
Appropriate storage conditions must be ensured either by controlling the temperature (eg, room, 
refrigeration unit) or by completion of a temperature log in accordance with local requirements 
on a regular basis (eg, once a week), showing actual and minimum/maximum temperatures 
reached over the time interval. 
In case an out-of-range temperature is noted, it must be immediately reported as per instructions 
contained in the IMP Handling Manual.  
7.6 
Drug accountability 
A Drug Accountability form will be used to record IMP dispensing and return information on a 
by-subject basis and will serve as source documentation during the course of the study. Details of 
any IMP lost, damaged (due to breakage or wastage), not used, partially used, disposed of at the 
study site, or returned to the Sponsor or designee must also be recorded on the appropriate forms. 
All supplies and pharmacy documentation must be made available throughout the study for UCB 
(or designee) to review. 
The Investigator (or designee) is responsible for retaining all used, unused, and partially used 
containers of IMP until returned or destroyed, taking into account local laws and regulations. 
The Investigator may assign some of the Investigator’s duties for drug accountability at the study 
site to an appropriate pharmacist/designee. 
The Investigator must ensure that the IMP is used only in accordance with the protocol. 
Periodically, and/or after completion of the clinical phase of the study, all used (including empty 
containers)/partially used, unused, damaged and/or expired IMP containers must be reconciled 
and either destroyed at the site according to local laws, regulations, and UCB standard operating 
procedures (SOPs), or returned to UCB (or designee). Investigational medicinal product intended 
for the study cannot be used for any other purpose than that described in this protocol. 
7.7 
Procedures for monitoring subject compliance 
At each visit after IMP is dispensed, subjects/guardians must return all unused IMP and empty 
IMP containers. Drug accountability must be done in the subject’s presence in order to obtain 
explanations regarding discrepancies in compliance with the dosing regimen. Drug 
accountability must be recorded on the Drug Accountability form. 
Site personnel who are administering iv BRV will record information about all doses 
administered, including the target dose, actual dose administered, and the dates and times of 
initiation and completion of each iv administration. If the actual dose is less or more than the 
target dose, the reason a partial or excessive dose was administered will be recorded.  
Intravenous solution will be administered under supervision of the Investigator or his/her 
designee. The noninjected volume will be recorded in the CRF. Compliance with the

recommended duration of the iv administration will also be assessed by recording the start time 
and the stop time in the CRF.  
Subjects who receive <75% or >125% of the planned BRV dose will be considered 
noncompliant. If a subject is found to be persistently noncompliant in the Investigator’s opinion, 
the Sponsor, in conjunction with the Investigator, will make a decision as to whether the subject 
should be withdrawn from the study. 
7.8 
Concomitant medication(s)/treatment(s) 
For any treatment other than the IMP, including over-the-counter products, an accurate record 
must be kept in the clinic chart (source documentation) and in the CRF. Concomitant 
medications should be recorded on the concomitant AED page or the concomitant non AED 
medication page of the CRF, according to the indication. New medications should be recorded in 
the CRF at only the first visit at which they are reported and subsequently only if there is a 
change. For any change, the start date corresponding to the date of change in administration 
should be recorded in the CRF. 
7.8.1 
Permitted concomitant treatments (medications and therapies) 
All treatments are permitted with the exception of those listed in Section 7.8.2.  
Vagus nerve stimulation is allowed and will be counted as a concomitant AED. A stable

Investigators may administer rescue medication in accordance with medical judgment at any 
time during the study. No rescue medication will be supplied by UCB. 
7.9 
Blinding 
This is an open-label study; no blinding is required. 
7.10 
Randomization and numbering of subjects 
Subjects will not be randomized in EP0065.  
For OLB subjects, the unique identification number assigned to them in the open-label study will 
be used to identify them and maintain subject confidentiality throughout EP0065.  
The RxB, IOB, and IIB subjects will be assigned a unique identification number for 
identification and to maintain subject confidentiality. To enroll these subjects, the Investigator or 
designee will contact the IRT and provide brief details about the subject to be enrolled. Each 
subject will receive a 5-digit number assigned at screening that serves as the subject identifier 
throughout the study. The subject number will be required in all communication between the 
Investigator or designee and the IRT regarding a particular subject. Subject numbers and kit 
numbers will be tracked via the IRT.

PK sampling may be performed at the discretion of the Investigator, especially in the event of a 
relevant treatment-emergent AE. 
Blood samples should be collected after completion of the ECG and the vital sign measurements 
and from a region of the body not used for the iv BRV administration. The date, start, and stop 
time of each iv administration and the date and time of each PK sampling must be recorded. 
Per subject, the maximum amount of blood collected for PK analyses and clinical laboratory 
assessments will not exceed a maximum of 3% of the subject’s total blood volume within 
4 weeks. 
Details of plasma sample collection and processing, sample labeling, and shipment will be

ASSESSMENT OF SAFETY 
10.1 
Adverse events 
10.1.1 
Definitions 
10.1.1.1 
Adverse event 
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product that does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a 
medicinal (investigational) product, whether or not related to the medicinal (investigational) 
product. 
In order to ensure complete safety data collection, all AEs occurring during the study (ie, after 
the signing of the ICF/Assent form), including any pretreatment and posttreatment periods 
required by the protocol, must be reported in the CRF even if no IMP was taken but specific 
study procedures were conducted. This includes all AEs not present prior to the initial visit and 
all AEs that recurred or worsened after the initial visit. 
Signs or symptoms of the condition/disease for which the IMP is being studied should be 
recorded as AEs only if their nature changes considerably or their frequency or intensity 
increases in a clinically significant manner as compared to the clinical profile known to the 
Investigator from the subject’s history or the Baseline Period. 
10.1.1.2 
Serious adverse event 
Once it is determined that a subject experienced an AE, the seriousness of the AE must be 
determined. A serious adverse event (SAE) must meet 1 or more of the following criteria: 
 Death 
 Life-threatening 
(Life-threatening does not include a reaction that might have caused death had it occurred in 
a more severe form.) 
 Significant or persistent disability/incapacity 
 Congenital anomaly/birth defect (including that occurring in a fetus) 
 Important medical event that, based upon appropriate medical judgment, may jeopardize the 
patient or subject and may require medical or surgical intervention to prevent 1 of the other 
outcomes listed in the definition of serious 
(Important medical events may include, but are not limited to, potential Hy’s Law [see 
Section 10.1.1.3], allergic bronchospasm requiring intensive treatment in an emergency room 
or at home, blood dyscrasias that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse.) 
 Initial inpatient hospitalization or prolongation of hospitalization 
(A patient admitted to a hospital, even if he/she is released on the same day, meets the 
criteria for the initial inpatient hospitalization. An emergency room visit that results in

admission to the hospital would also qualify for the initial inpatient hospitalization criteria. 
However, emergency room visits that do not result in admission to the hospital would not 
qualify for this criteria and, instead, should be evaluated for 1 of the other criteria in the 
definition of serious [eg, life-threatening adverse experience, important medical event]. 
Hospitalizations for reasons not associated with the occurrence of an AE [eg, preplanned 
surgery or elective surgery for a pre-existing condition that has not worsened or manifested 
in an unusual or uncharacteristic manner] do not qualify for reporting. For example, if a 
subject has a condition recorded on his/her medical history and later has a preplanned surgery 
for this condition, it is not appropriate to record the surgery or hospitalization as an SAE, 
since there is no AE upon which to assess the serious criteria. Please note that, if the 
pre-existing condition has worsened or manifested in an unusual or uncharacteristic manner, 
this would then qualify as an AE and, if necessary, the seriousness of the event would need to 
be determined.) 
10.1.1.2.1 
Anticipated serious adverse events 
The following Anticipated SAEs are anticipated to occur in the population studied in this 
protocol at some frequency that is independent of drug exposure.  
This list does not change the Investigator’s obligation to report all SAEs (including Anticipated 
SAEs) as detailed in Section 10.1.2.3.

Adverse events of special interest 
An AE of special interest is any AE that a regulatory authority has mandated be reported on an 
expedited basis, regardless of the seriousness, expectedness, or relatedness of the AE to the 
administration of a UCB product/compound. For this study, the AEs of special interest include:

 Autoimmune nephritis 
 Nephritis 
 Nephritis allergic 
 Tubulointerstitial nephritis 
 Tubulointerstitial nephritis and uveitis syndrome  
 Potential Hy’s Law, defined as ≥3xULN ALT or AST with coexisting ≥2xULN total 
bilirubin in the absence of ≥2xULN ALP, with no alternative explanation for the biochemical 
abnormality, must ALWAYS be reported to UCB as an AE of special interest (ie, without 
waiting for any additional etiologic investigations to have been concluded). Follow-up 
information should then be reported if an alternative etiology is identified during 
investigation and monitoring of the subject. 
10.1.2 
Procedures for reporting and recording adverse events 
The subject and/or caregiver (including parent/legal guardian) will be given the opportunity to 
report AEs spontaneously. A general prompt will also be given at each study visit to detect AEs. 
For example: 
“Did you notice anything unusual about your health (since your last visit)?” 
In addition, the Investigator should review any self-assessment procedures (eg, diary cards) 
employed in the study at each visit. 
The AEs should be recorded in the CRF at only the first visit at which they are reported and 
subsequently only if there is a change.  
10.1.2.1 
Description of adverse events 
When recording an AE, the Investigator should use the overall diagnosis or syndrome using 
standard medical terminology, rather than recording individual symptoms or signs. The CRF and 
source documents should be consistent. Any discrepancies between the subject’s and/or 
caregivers own words on his/her own records (eg, diary card) and the corresponding medical 
terminology should be clarified in the source documentation. 
Details for completion of the AE CRF (including judgment of relationship to IMP) are described 
in the CRF Completion Guidelines. 
10.1.2.2 
Rule for repetition of an adverse event 
An increase in the intensity of an AE should lead to the repetition of the AE being reported with: 
 The outcome date of the first AE that is not related to the natural course of the disease being 
the same as the start date of the repeated AE, and the outcome of “worsening” 
 The AE verbatim term being the same for the first and repeated AE, so that the repeated AE 
can be easily identified as the worsening of the first one 
10.1.2.3 
Additional procedures for reporting serious adverse events 
If an SAE is reported, UCB must be informed within 24 hours of receipt of this information by 
the site (see contact information for SAE reporting listed in the Serious Adverse Event Reporting

section at the front of the protocol). The Investigator must forward to UCB (or its representative) 
a duly completed “Investigator SAE Report Form for Development Drug” (SAE Report form) 
provided by UCB, even if the data are incomplete, or if it is obvious that more data will be 
needed in order to draw any conclusions. Information recorded on this form will be entered into 
the global safety database. 
An Investigator SAE Report form will be provided to the Investigator. The Investigator SAE 
Report form must be completed in English.  
It is important for the Investigator, when completing the SAE Report form, to include the 
assessment as to a causal relationship between the SAE and the IMP administration. This insight 
from the Investigator is very important for UCB to consider in assessing the safety of the IMP 
and in determining whether the SAE requires reporting to the regulatory authorities in an 
expedited manner. 
Additional information (eg, autopsy or laboratory reports) received by the Investigator must be 
provided within 24 hours. All documents in the local language must be accompanied by a 
translation in English, or the relevant information included in the same document must be 
summarized in the Investigator SAE Report form. 
The Investigator is specifically requested to collect and report to UCB (or its representative) any 
SAEs (even if the Investigator is certain that they are in no way associated with the IMP), up to 
30 days from the end of the study for each subject, and to also inform participating subjects of 
the need to inform the Investigator of any SAE within this period. Serious AEs that the 
Investigator thinks may be associated with the IMP must be reported to UCB regardless of the 
time between the event and the end of the study. 
Upon receipt of the SAE Report form, UCB will perform an assessment of expectedness of the 
reported SAE. The assessment of the expectedness of the SAE is based on the Investigator’s 
Brochure for BRV. 
10.1.3 
Follow up of adverse events 
An AE should be followed until it has resolved, has a stable sequelae, the Investigator 
determines that it is no longer clinically significant, or the subject is lost to follow up. This 
follow-up requirement applies to AEs, SAEs, and AEs of special interest; further details 
regarding follow up of PDILI events is provided in Section 10.2.1.4. 
If an AE is ongoing at the end of the study for a subject, follow up should be provided until 
resolution/stable level of sequelae is achieved, or until the Investigator no longer deems that it is 
clinically significant, or until the subject is lost to follow up. If no follow up is provided, the 
Investigator must provide a justification. The follow up will usually be continued for 30 days 
after the subject has discontinued his/her IMP. 
Information on SAEs obtained after clinical database lock will be captured through the Patient 
Safety (PS) database without limitation of time. 
If new or worsened infusion-site related AEs are reported during TC-1, the subject should return 
for an Unscheduled Visit as soon as possible for further assessment.

10.1.4 
Pregnancy 
If an Investigator is notified that a subject has become pregnant after the first intake of any IMP, 
the Investigator must immediately notify UCB’s PS department by providing the completed 
Pregnancy Report and Outcome form (for contact details see SAE reporting information at the 
beginning of this protocol). The subject should be withdrawn from the study as soon as 
pregnancy is known (by positive pregnancy test), and the following should be completed: 
 The subject should immediately stop the intake of BRV or be down-titrated as instructed by 
the Investigator. 
 For subjects who have BRV down-titrated: 
 Return for Visit 13. 
 TC-3 should be scheduled 2 weeks after the subject has discontinued BRV. 
The Investigator must inform the subject of information currently known about potential risks 
and about available treatment alternatives. 
The pregnancy will be documented on the Pregnancy Report and Outcome form provided to the 
Investigator. The progression of the pregnancy and the eventual birth (if applicable) must be 
followed up using the Pregnancy Report and Outcome form in which the Investigator has to 
report on the health of the mother and of the child. Every reasonable attempt should be made to 
follow the health of the child for 30 days after birth for any significant medical issues. In certain 
circumstances, UCB may request that follow up is continued for a period longer than 30 days. If 
the subject is lost to follow up and/or refuses to give information, written documentation of 
attempts to contact the subject needs to be provided by the Investigator and filed at the site. 
UCB’s PS department is the primary contact for any questions related to the data collection for 
the pregnancy, eventual birth, and follow up. 
In cases where the partner of a male subject enrolled in a clinical study becomes pregnant, the 
Investigator or designee is asked to contact the subject to request consent of the partner via the 
Partner Pregnancy Consent form that has been approved by the responsible IRB/IEC and should 
be available in the Investigator site file. In case of questions about the consent process, the 
Investigator may contact the UCB/contract research organization (CRO) contract monitor for the 
study. The Investigator will complete the Pregnancy Report and Outcome form and send it to 
UCB’s PS department (for contact details see SAE reporting information at the beginning of this 
protocol) only after the partner has agreed that additional information can be captured and has 
provided the signed Partner Pregnancy Consent form. UCB’s PS department is also the primary 
contact for any questions related to the data collection for the partner pregnancy, eventual birth, 
and follow up. 
A pregnancy becomes a SAE in the following circumstances: miscarriage, abortion (elective or 
spontaneous), unintended pregnancy after hormonal contraceptive failure (if the hormonal 
contraceptive was correctly used), ectopic pregnancy, fetal demise, or any congenital 
anomaly/birth defect of the baby. Those SAEs must be additionally reported using the 
Investigator SAE Report form.

10.1.5 
Suspected transmission of an infectious agent via a medicinal 
product 
A suspected transmission of infectious agent is defined as any infection that is temporally related 
to the administration of the medicinal product with no other likely cause. The medical monitor 
should be contacted immediately. No further medicinal product from that specific batch should 
be administered. Infections should be treated according to normal clinical practice. 
For the purposes of reporting, any suspected transmission of an infectious agent via a medicinal 
product should be considered as an SAE; such cases must be reported immediately, recorded in 
the AE module of the CRF, and followed as any other SAE. Any organism, virus, or infectious 
particle (eg, prion protein transmitting transmissible spongiform encephalopathy), pathogenic or 
nonpathogenic, is considered an infectious agent. 
10.1.6 
Overdose of investigational medicinal product 
Excessive dosing (beyond that prescribed in the protocol and including overdose) should be 
recorded in the CRF. Any SAE or nonserious AE associated with excessive dosing must be 
followed as any other SAE or nonserious AE. These events are only considered AEs or SAEs if 
there are associated clinical signs and symptoms or if the act of taking the excess medicine itself 
is an AE or SAE (eg, suicide attempt). 
10.1.7 
Safety signal detection 
Selected data from this study will be reviewed periodically to detect as early as possible any 
safety concern(s) related to the IMP so that Investigators, clinical study subjects, regulatory 
authorities, and IRBs/IECs will be informed appropriately and as early as possible. 
The Study Physician or medically qualified designee/equivalent will conduct an ongoing review 
of SAEs and perform ongoing SAE reconciliations in collaboration with the PS representative. 
As appropriate for the stage of development and accumulated experience with the IMP, 
medically qualified personnel at UCB may identify additional safety measures (eg, AEs, vital 
signs, laboratory or ECG results) for which data will be periodically reviewed during the course 
of the study. 
For further details please refer to Section 12.7.  
10.2 
Laboratory measurements 
Laboratory assessments for safety (including hematology, chemistry, and endocrinology for all 
subjects, and urinalysis for subjects for whom sample collection is feasible) will be conducted 
using standard methods at a central laboratory. The central laboratory will provide the 
Investigator with dedicated, standardized sampling supplies (labels, needles, tubes) and a 
study-specific laboratory manual, which will explain how to use the supplies and how to ship the 
samples to the central laboratory.  
Pregnancy tests (urine) for female subjects of childbearing potential will be performed locally. 
Table 10‒2 provides a list of laboratory parameters that will be assessed.

The PDILI IMP discontinuation criteria for this study are provided in Section 6.3.1, with the 
accompanying required follow-up investigation and monitoring detailed below. All PDILI events 
must be reported as an AE and reported to the study site and Sponsor within 24 hours of learning

of their occurrence. Any PDILI event that meets the criterion for potential Hy’s Law must be 
reported as an AE of special interest (see Section 10.1.1.3), and, if applicable, also reported as an 
SAE (see Section 10.1.2.3 ).  
Evaluation of PDILI consists of the diagnostic testing and continued monitoring included in 
Table 10‒3 (specific tests dependent on laboratory results and corresponding symptoms) and 
consultation with a local hepatologist (if applicable; discussed in Section 10.2.1.1). The local 
hepatologist is the expert usually consulted by the treating physician for assessment and 
management of potential hepatic disease. This would usually be a hepatologist, but may be a 
gastroenterologist. Additional investigation and monitoring may be required and adapted based 
on the diagnosis after the cause of the liver injury/abnormality is confirmed (details in 
Section 10.2.1.4).  
The results of all monitoring, including laboratory testing and other testing, should be made 
available to the study site and Sponsor. 
All initial tests resulting in abnormal hepatic laboratory values need to be repeated, but 
appropriate medical action must not be delayed waiting for the repeat result. 
If tests are done locally for more rapid results, a concurrent sample should also be sent to the 
central laboratory whenever possible. Medical care decisions are to be made initially using the 
most rapidly available results and a conservative approach must be taken if the results from the 
2 laboratory tests are significantly different. Data from the local and central laboratory are to be 
recorded on the applicable CRF pages. 
When IMP is discontinued, all concomitant medications and herbal supplements that are not 
medically necessary should also be discontinued. In these cases, the Investigator should also 
consider dose reduction for medically necessary concomitant medication and consider changing 
any medically required concomitant medication known to be hepatotoxic to a suitable 
alternative. 
Rechallenge with a substance potentially causing drug-induced liver injury is dangerous, may be 
fatal, and must not occur. 
The table below summarizes the approach to investigate PDILI.

10.2.1.1 
Consultation with Medical Monitor and local hepatologist  
Potential drug-induced liver injury events require notification of the Medical Monitor within 
24 hours (eg, by laboratory alert), and the subject must be discussed with the Medical Monitor as 
soon as possible. If required, the subject must also be discussed with the local hepatologist. The 
local hepatologist is the expert usually consulted by the treating physician for assessment and 
management of potential hepatic disease. This would usually be a hepatologist, but may be a 
gastroenterologist. If determined necessary, this discussion should be followed by a full 
hepatology assessment (see Section 10.2.1.3) and SAE report (if applicable). 
10.2.1.2 
Immediate action: determination of IMP discontinuation 
All PDILI events require immediate action, testing, and monitoring.  
The immediate action is dependent on the laboratory values and symptoms of hepatitis or 
hypersensitivity and ranges from continuation of IMP (followed by immediate investigation) to 
immediate and permanent discontinuation (see Section 6.3.1 and Table 10‒3 for details). 
When IMP is discontinued, all concomitant medications and herbal supplements that are not 
medically necessary should also be discontinued. The Investigator should also consider dose 
reduction of medically necessary concomitant medication and consider changing any medically 
required concomitant medication known to be hepatotoxic to a suitable alternative. 
10.2.1.3 
Testing: identification/exclusion of alternative etiology 
The measurements and additional information required for the assessment of PDILI events when 
there is a reasonable possibility that they may have been caused by the IMP are detailed in 
Table 10‒4 (laboratory measurements) and Table 10‒5 (additional information). Results of the 
laboratory measurements and information collected are to be submitted to the Sponsor on the 
corresponding CRF. If the medical history of the subject indicates a requirement for other 
assessments not included below, these additional assessments should be completed and 
submitted, as applicable. 
All blood samples should be stored, if possible. If tests are done locally for more rapid results, a 
concurrent sample must also be sent to the central laboratory. 
The following measurements are to be assessed:

consultation with the hepatologist (as applicable) and UCB responsible physician, as needed. 
10.3 
Other safety measurements 
All safety assessments are to be conducted at the times specified in the Schedules of Study 
Assessments (Table 5‒1 and Table 10-6). During the iv PK Period, intensive assessments of 
ECGs and vital signs are to be conducted at the times specified in Table 5‒2 (15-minute 
[±3 minutes] infusion) and Table 5‒3 (bolus [up to 2-minute infusion]). 
10.3.1 
ECG 
Standard 12-lead ECGs will be performed.

10.3.2 
Vital signs 
Vital signs assessments will include BP (systolic and diastolic), pulse rate, RR, and temperature. 
Vital sign assessments will be performed after the subject is at rest for at least 3 minutes, when 
feasible. If subjects have an abnormal vital sign value, the measurement will be repeated at the 
Investigator’s discretion.  
Possibly clinically significant (PCS) vital sign values are defined as those PCS values which 
occur at any time during the study. Additional monitoring of BP is necessary if a low PCS BP 
value occurs at 2 hours after the start of an infusion (Section 5.2). An overview of PCS 
abnormality criteria for BP is presented in Table 10-6.

Assessment of suicidality 
Suicidal ideation and behavior be assessed by trained study personnel using the C-SSRS for 
subjects ≥6 years of age. This scale will be used for screening as well as to assess suicidal 
ideation and behavior that may occur during the study. The C-SSRS will be completed according 
to the tabular schedule of study assessments (Section 5.2). 
The Investigator’s decision about subject continuation in the study or subject withdrawal from 
the study if the subject has a positive response to the C-SSRS Question 4, should be based on the 
benefit/risk balance for continuation or discontinuation of study treatment in view of the 
individual subject circumstances, condition, attained efficacy, causality, alternative risk 
management options, etc. Details of the case must be documented by the Investigator (Principal 
Investigator or other medically qualified staff conducting the C-SSRS) and provided to UCB via 
the SAE reporting process.  
All subjects who are ≥6 years of age will complete the following version of the C-SSRS as 
indicated:

Subjects should be monitored for any changes in mood, ideas, or behavior for warning signs of 
depression. The Investigator should be aware of common warning signs that might be a signal 
for risk of depression. For common signs and symptoms of depression in children younger than 
6 years old, reference should be made to the current version of the Diagnostic and Statistical 
Manual of Mental Disorders. Parents and caregivers should also be advised accordingly and 
effort should be made at clinic visits to specifically assess potential depression.

STUDY MANAGEMENT AND ADMINISTRATION  
11.1 
Adherence to protocol 
The Investigator should not deviate from the protocol. However, the Investigator should take any 
measure necessary in deviation from or not defined by the protocol in order to protect clinical 
study subjects from any immediate hazard to their health and safety. In this case, this action 
should be taken immediately, without prior notification of the regulatory authority, IRB/IEC, or 
Sponsor. 
After implementation of such measure, the Investigator must notify the Clinical Project Manager 
of the Sponsor within 24 hours and follow any local regulatory requirements. 
11.2 
Monitoring 
Monitoring of the study will be delegated by UCB to a CRO. The CRO will monitor the study to 
meet the Sponsor’s monitoring SOPs, ICH-GCP guideline, and applicable regulatory 
requirements, and to ensure that study initiation, conduct, and closure are adequate.  
The Investigator and his/her staff are expected to cooperate with UCB (or designee) and to be 
available during the monitoring visits to answer questions sufficiently and to provide any 
missing information. The Investigator(s)/institution(s) will permit direct access to source 
data/documents for study-related monitoring, audits, IRB/IEC review, and regulatory 
inspection(s). 
The Investigator will allow UCB (or designee) to periodically review all CRFs and 
corresponding source documents (eg, hospital and laboratory records for each study participant). 
Monitoring visits will provide UCB (or designee) with the opportunity to evaluate the progress 
of the study, verify the accuracy and completeness of CRFs, ensure that all protocol

requirements, applicable authorities regulations, and Investigator’s obligations are being 
fulfilled, and resolve any inconsistencies in the study records. 
11.2.1 
Definition of source data  
All source documents must be accurate, clear, unambiguous, permanent, and capable of being 
audited. They should be made using some permanent form of recording (ink, typing, printing, 
optical disc). They should not be obscured by correction fluid or have temporary attachments 
(such as removable self-stick notes). Printouts of CRF screens are not considered acceptable 
source documents. 
Source documents are original records in which raw data are first recorded. These may include 
hospital/clinic/general practitioner records, charts, diaries, x-rays, laboratory results, printouts, 
pharmacy records, care records, ECG or other printouts, completed scales, quality of life 
questionnaires, or video, for example. Source documents should be kept in a secure, limited 
access area. 
Original laboratory results and ECGs are considered as source documents and should be placed 
and stored with the subject’s study information. 
Source documents that are computer generated and stored electronically must be printed for 
review by the monitor (eg, ECG reports). Once printed, these copies should be signed and dated 
by the Investigator and become a permanent part of the subject’s source documents. The 
Investigator will facilitate the process for enabling the monitor to compare the content of the 
printout and the data stored in the computer to ensure all data are consistent. 
Electronic data records must be saved and stored as instructed by UCB (or designee). 
11.2.2 
Source data verification 
Source data verification ensures accuracy and credibility of the data obtained. During monitoring 
visits, reported data are reviewed with regard to being accurate, complete, and verifiable from 
source documents (eg, subject files, recordings from automated instruments, tracings [ECG], 
x-ray films, laboratory notes). All data reported on the CRF should be supported by source 
documents, unless otherwise specified in Section 11.2.1. 
11.3 
Data handling 
11.3.1 
Case Report form completion 
The Investigator is responsible for prompt reporting of accurate, complete, and legible data in the 
electronic CRFs and in all required reports. 
Any change or correction to the CRF after saving must be accompanied by a reason for the 
change. 
Corrections made after the Investigator’s review and approval (by means of a 
password/electronic signature) will be reapproved by the Investigator. 
The Investigator should maintain a list of personnel authorized to enter data into the electronic 
CRF. 
Detailed instructions will be provided in the CRF Completion Guidelines.

11.3.2 
Database entry and reconciliation 
Case Report forms/external electronic data will be entered/loaded into a validated electronic 
database using a clinical data management system (CDMS). Computerized data cleaning checks 
will be used in addition to manual review to check for discrepancies and to ensure consistency of 
the data. The data are entered into the electronic CRFs once and are subsequently verified. 
An electronic audit trail system will be maintained within the CDMS to track all data changes in 
the database once the data have been saved initially into the system or electronically loaded. 
Regular backups of the electronic data will be performed. 
11.3.3 
Subject Screening and Enrollment log/Subject Identification Code list 
The subject’s screening and enrollment will be recorded in the Subject Screening and Enrollment 
Log. 
The Investigator will keep a Subject Identification Code list. This list remains with the 
Investigator and is used for unambiguous identification of each subject. 
The subject’s consent and enrollment in the study must be recorded in the subject’s medical 
record. These data should identify the study and document the dates of the subject’s 
participation. 
11.4 
Termination of the study 
UCB reserves the right to temporarily suspend or prematurely discontinue this study either at a 
single site, multiple sites, or at all sites at any time for reasons including, but not limited to, 
safety or ethical issues, inaccurate or incomplete data recording, noncompliance, or 
unsatisfactory enrollment with respect to quality or quantity. 
If the study is prematurely terminated or suspended, UCB (or its representative) will inform the 
Investigators/institutions and the regulatory authority(ies) of the termination or suspension and 
the reason(s) for the termination or suspension, in accordance with applicable regulatory 
requirement(s). The IRB/IEC should also be informed and provided with reason(s) for the 
termination or suspension by the Sponsor or by the Investigator/institution, as specified by the 
applicable regulatory requirement(s). In addition, arrangements will be made for the return of all 
unused IMP and other material in accordance with UCB procedures for the study. 
11.5 
Archiving and data retention  
The Investigator will maintain adequate records for the study, including CRFs, medical records, 
laboratory results, Informed Consent documents, drug dispensing and disposition records, safety 
reports, information regarding participants who discontinued, and other pertinent data. 
All essential documents are to be retained by the Investigator until at least 2 years after the last 
approval of a marketing application in an ICH region and until there are no pending or 
contemplated marketing applications in an ICH region, or at least 2 years have elapsed since the 
formal discontinuation of clinical development of the IMP. These documents should be retained 
for a longer period, however, if required by the applicable regulatory requirement(s) or by an 
agreement with UCB (CPMP/ICH/135/95, 2002 [Section 4.9.5]). The Investigator will contact 
UCB for authorization prior to the destruction of any study records or in the event of accidental 
loss or destruction of any study records. The Investigator will also notify UCB should he/she

relocate or move the study-related files to a location other than that specified in the Sponsor’s 
study master file. 
11.6 
Audit and inspection 
The Investigator will permit study-related audits mandated by UCB, after reasonable notice, and 
inspections by domestic or foreign regulatory authorities. 
The main purposes of an audit or inspection are to confirm that the rights and well-being of the 
subjects enrolled have been protected, that enrolled subjects (ie, signing consent and undergoing 
study procedures) are appropriate for the study, and that all data relevant for the evaluation of the 
IMP have been processed and reported in compliance with the planned arrangements, the 
protocol, investigational site, and IRB/IEC SOPs, ICH GCP, and applicable regulatory 
requirements. 
The Investigator will provide direct access to all study documents, source records, and source 
data. If an inspection by a regulatory authority is announced, the Investigator will immediately 
inform UCB (or designee). 
11.7 
Good Clinical Practice 
Noncompliance with the protocol, ICH-GCP, or local regulatory requirements by the 
Investigator, institution, institution staff, or designees of the Sponsor will lead to prompt action 
by UCB to secure compliance. Continued noncompliance may result in the termination of the 
site’s involvement in the study. 
12 
STATISTICS 
A description of statistical methods follows and will be described in more detail in the Statistical 
Analysis Plan. 
12.1 
Definition of analysis sets 
The Safety Set iv (SS-iv) will include subjects who received at least 1 dose of iv BRV. The SS-iv 
will be the primary analysis set for the analysis of safety data. 
The Safety Set (SS) will include subjects who received at least 1 dose of BRV (oral or iv). 
Selected safety summaries will be presented for the SS. 
The PK Per-protocol Set (PK-PPS) will include all subjects in the SS having provided at least 
1 measurable postdose plasma sample (with recorded sampling time) during the iv PK Period 
with documented iv BRV intake times. 
12.2 
General statistical considerations 
All computations for the non-PK analyses will be performed using SAS® version 9.3 or later 
(SAS Institute, NC, USA).  
Selected disposition, exposure, demographic, and baseline summaries will be presented by

for the purpose of analysis. For continuous variables, display of descriptive statistics will 
generally include n (number of subjects), mean, standard deviation (SD), median, minimum, and 
maximum. 
12.3 
Planned PK analyses 
Descriptive statistics for BRV plasma concentrations, including but not limited to geometric 
mean and coefficient of variation percentages, will be computed for pre-bolus/infusion and at the 
post-bolus/infusion time points on each for iv BRV administration during the iv PK Period. 
12.4 
Planned safety analyses 
Safety data will be reported in epochs that include the pre-bolus/infusion period(s), the 
bolus/infusion period(s), the period(s) immediately post-bolus/infusion, and period(s) between 
each subsequent bolus/infusion(s). These data will include vital signs, ECGs, and AE reporting.  
12.4.1 
Analysis of safety variables 
Descriptive statistics for the safety variables will be presented by cohort and infusion duration, 
cohorts overall, and all subjects overall. Additional summaries will include a summary of the 
OLB, RXB, IOB, and IIB groups by cohort and infusion duration. 
12.4.1.1 
Primary safety variables 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA®). Adverse events will be summarized by MedDRA System Organ Class and 
Preferred Term. 
The primary safety variables will be summarized for the iv PK Period for the SS-iv. Summaries 
of adverse events will also be presented by study period for the SS and epochs relative to 
bolus/infusion for the SS-iv. 
12.4.1.2 
Other safety variables 
Inferential statistical tests are not planned for the other safety variables. In general, for 
continuous safety variables including ECG measurements including corrected QT interval, and 
vital sign measurements, the descriptive analyses (n, mean, SD, median, minimum, maximum) 
for the actual measurement and its change from baseline (defined as most recent pre-iv BRV 
measurement) will be presented by epochs relative to bolus/infusion. When analyzing categorical 
data, the number and percentage of subjects in each category will be presented. In addition, shift 
tables may be used to evaluate the number and percentage of subjects having a different post-iv 
BRV status when compared with their pre-iv BRV status for each bolus/infusion. Changes in 
vital signs and ECG parameters will be presented graphically for epochs relative to 
bolus/infusion. 
12.5 
Handling of protocol deviations 
Important protocol deviations are deviations from the protocol which potentially could have a 
meaningful impact on the primary safety outcomes for an individual subject. The criteria for 
identifying important protocol deviations will be defined within the appropriate protocol-specific 
document. Important protocol deviations will be reviewed as part of the ongoing data cleaning 
process and data evaluation. All important deviations will be identified and documented prior to 
database lock to confirm exclusion from analysis sets.

Handling of dropouts or missing data 
No specific procedure is foreseen for handling dropouts or missing data. 
12.7 
Planned interim analysis and data monitoring 
No formal interim analysis is planned for this study.  
For the first cohort, after the first half of the subjects receive the 15-minute infusion(s), the DMC 
will meet to review safety (as indicated in the DMC charter) and, as available, PK data. For 
subsequent cohorts, the DMC will review data for bolus infusions of the previous cohort and the 
15-minute infusions of the current cohort. The DMC will meet no less than approximately every 
6 months commensurate with enrollment. 
12.8 
Determination of sample size 
The primary objective of the study is to evaluate the PK, safety, and tolerability of BRV given 
intravenously. The plan for approximately 50 enrolled subjects (4 cohorts of 
approximately12 subjects each) to receive iv BRV was deemed clinically appropriate for the 
evaluation of the PK, safety, and tolerability of iv BRV administration in subjects ≥1 month to 
<16 years of age with epilepsy. No formal sample size calculation has been performed.

ETHICS AND REGULATORY REQUIREMENTS 
13.1 
Informed consent 
Subject’s informed consent must be obtained and documented in accordance with local 
regulations, ICH-GCP requirements, and the ethical principles that have their origin in the 
principles of the Declaration of Helsinki. 
Prior to obtaining informed consent, information should be given in a language and at a level of 
complexity understandable to the subject in both oral and written form by the Investigator (or 
designee). Each subject will have the opportunity to discuss the study and its alternatives with 
the Investigator. 
Prior to participation in the study, the written Informed Consent form should be signed and 
personally dated by the subject, or his/her legal representative, and by the person who conducted 
the informed consent discussion (Investigator or designee). The subject or his/her legal 
representative must receive a copy of the signed and dated Informed Consent form. As part of 
the consent process, each subject must consent to direct access to his/her medical records for 
study-related monitoring, auditing, IRB/IEC review, and regulatory inspection. In addition, a 
Consent form or a specific Assent form, where required, will be signed and dated by minors. 
Any subject who becomes 16 years of age during EP0065 must sign and date the Informed 
Consent form according to local regulations. 
If the ICF/Assent form is amended during the study, the Investigator (or the Sponsor, if 
applicable) must follow all applicable regulatory requirements pertaining to the approval of the 
amended Informed Consent form by the IRB/IEC and use of the amended form. 
All studies conducted at centers in the United States must include the use of a Health Insurance 
Portability and Accountability Act Authorization form.

The subject or legal representative may withdraw consent for the subject to participate in the 
study at any time. A subject is considered as enrolled in the study when the subject or legal 
representative has signed the ICF form/Assent form. A CRF must not be started, nor may any 
study specific procedure be performed for a given subject, without having obtained the written 
consent of the subject or legal guardian for the subject to participate in the study. 
13.2 
Subject identification cards 
Upon signing the ICF and Assent form (as applicable), the subject or legal representative will be 
provided with a subject identification card in the language of the subject. The Investigator will 
fill in the subject identifying information and medical emergency contact information. The 
Investigator will instruct the subject to keep the card with him/her at all times. 
13.3 
Institutional Review Boards and Independent Ethics 
Committees 
The study will be conducted under the auspices of an IRB/IEC, as defined in local regulations, 
ICH-GCP, and in accordance with the ethical principles that have their origin in the Declaration 
of Helsinki. 
The Investigator/UCB (or designee) will ensure that an appropriately constituted IRB/IEC that 
complies with the requirements of the current ICH-GCP version or applicable country-specific 
regulations will be responsible for the initial and continuing review and approval of the clinical 
study. Prior to initiation of the study, the Investigator/UCB (or designee) will forward copies of 
the protocol, ICF/Assent form, Investigator’s Brochure, Investigator’s curriculum vitae (if 
applicable), advertisement (if applicable), and all other subject-related documents to be used for 
the study to the IRB/IEC for its review and approval. 
Before initiating a study, the Investigator will have written and dated full approval from the 
responsible IRB/IEC for the protocol. 
The Investigator will also promptly report to the IRB/IEC all changes in the study, all 
unanticipated problems involving risks to human subjects or others, and any protocol deviations, 
to eliminate immediate hazards to subjects. 
The Investigator will not make any changes in the study or study conduct without IRB/IEC 
approval, except where necessary to eliminate apparent immediate hazards to the subjects. For 
minor changes to a previously approved protocol during the period covered by the original 
approval, it may be possible for the Investigator to obtain an expedited review by the IRB/IEC as 
allowed. 
As part of the IRB/IEC requirements for continuing review of approved studies, the Investigator 
will be responsible for submitting periodic progress reports to the IRB/IEC (based on IRB/IEC 
requirements), at intervals appropriate to the degree of subject risk involved, but no less than 
once per year. The Investigator should provide a final report to the IRB/IEC following study 
completion. 
UCB (or its representative) will communicate safety information to the appropriate regulatory 
authorities and all active Investigators in accordance with applicable regulatory requirements. 
The appropriate IRB/IEC will also be informed by the Investigator or the Sponsor, as specified 
by the applicable regulatory requirements in each concerned country. Where applicable,

APPENDIX 
16.1 
Protocol Amendment 1 
Rationale 
This nonsubstantial amendment is based on DMC recommendation, as a precaution additional 
safety monitoring has been added to the protocol. This precaution was not based on any related 
AE or reported symptoms. Additional vital sign measurements, specifically blood pressure, and 
criteria for further iv BRV dose allocation were added to further investigate blood pressure 
changes and ensure safety. Additionally, height measurements have been collected at various 
visits since the onset of the study, while these were inadvertently absent from the list of 
assessments. The protocol has therefore been aligned.
