SUMMARY
UCB0942 is a new chemical entity with selective affinity for synaptic vesicle glycoprotein 2 
(SV2) and for the benzodiazepine-binding site (cBZR) on the gamma-aminobutyric acid 
receptor type A (GABA-A). UCB0942 has shown superior efficacy in several preclinical 
models of epilepsy.
EP0069 is a Phase 2A, double-blind, randomized, placebo-controlled, multicenter study that 
will test the potential efficacy, safety/tolerability, and pharmacokinetic (PK) profile of 
UCB0942 in adult subjects with highly drug-resistant focal epilepsy. Randomization will be 
in a 1:1 ratio. 
The primary objective of the study is to evaluate the efficacy of UCB0942 administered 
concomitantly with each subject’s current, stable antiepileptic drug (AED) regimen in 
subjects who have 4 or more focal seizures with or without secondary generalization per 
week and who have failed to achieve seizure control with ≥4 AED regimens of adequate dose 
and duration. In this protocol, unless otherwise specified, “focal seizures” refers to partial-
onset seizures of type IA1, IB, and IC, but does not include type IA2, IA3, or IA4 seizures.
The secondary objectives are to evaluate the safety and tolerability of UCB0942 and to 
evaluate the steady-state PK of UCB0942 and its metabolites.
This study consists of:
!
A 4-week prescreening Historical Baseline Period for study eligibility purposes
!
A Screening Visit followed by a 2- to 3-week postscreening Prospective Outpatient 
Baseline Period (Day BL1 to Day BL14-21)
!
A 3-week Inpatient Period which consists of:
∀
An Inpatient Titration Week (Day T1 to Day T7)
∀
An Inpatient Maintenance-Dose Week (Day MD1 to Day MD7)
∀
An Inpatient Transition-to-Outpatient Week (Day TTO1 to Day TTO7)
!
An open-label Outpatient Maintenance Period of 8 weeks (Day OP1 to Day OP57)
!
A Tapering Period of 2 weeks (Day TOO1 to Day TOO14)
!
A Safety Follow-Up (SFU) Period of 4 weeks (Day SFU1 to Day SFU28)
!
An echocardiogram during dosing and after the last dose (the SFU7 echocardiogram). 
The echocardiogram will be repeated at 6 months (±1 month) after the last dose in the 
following subjects:
∀
Subjects who complete this study but do not enter the OLE study
∀
Subjects who withdraw from the Outpatient Period 
∀
Subjects who withdraw from the Inpatient Period and have an abnormal SFU7 
echocardiogram
Titration to UCB0942 400mg bid will occur over the course of 1 week in the clinical unit. 
For subjects in the active arm, doses will be titrated to UCB0942 400mg bid during the first 
inpatient week. For subjects who initially received placebo, doses will be titrated to 
UCB0942 400mg bid during the last week of the Inpatient Period. Dose reductions will be 
allowed during titration and maintenance in the Inpatient Period, but this should be discussed

with the Sponsor Study Physician unless this is not possible due to the circumstances. 
Multiple adjustments (tapering or increase) of the dose are allowed during the Outpatient 
Maintenance Period (minimum 100mg bid and maximum 400mg bid); however, any change 
of dose in the Outpatient Maintenance Period should first be discussed with the Sponsor 
Study Physician.
The total duration for subject participation in the study will be up to 20 weeks, plus an
echocardiographic follow-up visit 6 months after the last dose of study medication. The total 
duration of exposure to UCB0942 is 13 weeks in EP0069. Subjects who experience 
substantial benefit from UCB0942 with acceptable tolerability according to the subject and 
Investigator, will have the opportunity to continue taking UCB0942 in an open-label 
extension (OLE) study. Each subject’s decision to enter the OLE study will be in 
consultation with their neurologist and taking into account the potential risks and benefits of 
continuing to take UCB0942 and the potential risks and benefits of other treatment options. 
Subjects who enter the OLE study will not have a Tapering Period at the end of the 
Outpatient Maintenance Period. The OLE study is described in a separate protocol (EP0073).
The primary efficacy measure is the 75% responder rate (75%RR, proportion of subjects who 
achieve ≥75% reduction in focal seizure frequency) during the Inpatient Period compared to 
the 2-week Prospective Outpatient Baseline Period.
Secondary efficacy variables include:
!
Median percent reduction in weekly focal seizure frequency from the Prospective
Outpatient Baseline Period to the Inpatient Period and the End of Treatment.
!
Seizure-free rate during the Inpatient Period, the last 4 weeks of the Outpatient
Maintenance Period, and at the End of Treatment.
!
The 75%RR during the last 4 weeks of the Outpatient Maintenance Period and at the End
of Treatment.
!
Percentage of seizure-free days during the Inpatient and Outpatient Periods.
The exploratory efficacy variables are detailed in Section 4.1.3.
Plasma concentrations of UCB0942, and its identified metabolites 
, will be determined from blood samples obtained in the study in order to 
investigate the PK of UCB0942 and its major metabolites.
Blood samples for deoxyribonucleic acid (DNA), messenger ribonucleic acid (mRNA), and 
lipidomics/proteomics/additional blood biomarkers will be collected during the study for 
exploratory biomarker studies.
The safety of participating subjects will be closely monitored. Assessment of specific 
domains of psychiatric and cognitive symptoms will be performed by a staff member trained 
in the identification of psychiatric symptoms.
Other safety variables are detailed in Section 4.4.

INTRODUCTION
2.1
General background
In Europe and North America there are 350,000 to 500,000 (3 to 4 million worldwide) 
patients with focal epilepsy who have not been able to achieve freedom from disabling 
seizures despite sequential and/or combination treatment with several of the available AEDs. 
Despite the introduction of 12 new AEDs over the last 2 decades, the proportion of patients

with epilepsy who are unable to achieve complete control of their seizures has only decreased 
minimally, from 36% to 34% (Brodie et al, 2012), highlighting the large unmet medical need 
and the fact that recently-developed AEDs have not been able to meet this medical need. 
Patients with focal epilepsy who have failed to achieve seizure control with 2 or more AED 
regimens are defined as drug-resistant by the International League Against Epilepsy (ILAE; 
Kwan et al, 2010). It is important to highlight that there is a continuum of degrees of drug 
resistance within the patient population classified as drug-resistant according to ILAE 
criteria. When a patient with focal epilepsy has failed to achieve seizure freedom after the 
second AED regimen, he or she has less than 10% chance of achieving complete seizure 
control with subsequent AED regimens (Steinhoff, 2014; Beyenburg et al, 2012; Chung et al, 
2010; Schiller and Najjar, 2008; Mohanraj and Brodie, 2006). The likelihood of achieving 
complete seizure control diminishes as the number of failed AED regimens increases. Thus, 
when a patient with focal epilepsy has not been able to control their seizures despite 
treatment with 5 or more AED regimens, the likelihood of achieving complete seizure control 
with another AED regimen is 1-6% (Schiller and Najjar, 2008; Mohanraj and Brodie, 2006; 
UCB internal data on lacosamide and brivaracetam [BRV]). In addition, high-seizure 
frequency also correlates with reduced likelihood of achieving seizure freedom. For instance, 
patients who have failed 3 or 4 AED regimens but who have daily seizures have only a 2% 
chance of becoming seizure free with subsequent AEDs. In this study, to ensure that subjects 
who participate have a very low likelihood of benefiting from existing treatments, we will 
combine 2 criteria to identify the target population: failure to control seizures despite 
treatment with at least 4 AED regimens and having at least 4 seizures per week on average. 
This group of patients will be referred to as having “highly drug-resistant focal epilepsy.”
Resective surgery is an option for some patients with drug-resistant focal epilepsy. The ILAE 
recommends that patients be evaluated for surgery after failing to achieve seizure freedom 
with the second AED regimen; however, in most places patients are referred for surgery only 
after failing multiple AED regimens. Therefore, the patients who in practice are evaluated for 
and undergo surgery are similar to the highly drug-resistant population as defined above. Due 
to various factors (limited number of epilepsy surgery centers, inability to localize the seizure 
focus during work-up, contraindications to surgery, etc) fewer than 1% of patients with drug-
resistant focal epilepsy undergo epilepsy surgery. Therefore, the vast majority of patients 
with highly drug-resistant focal epilepsy have no treatment options (pharmacological or 
surgical) that can provide complete seizure control or even substantial reduction in the 
number of seizures.
UCB0942 has shown superior efficacy in several preclinical models of epilepsy. UCB0942 is 
superior to levetiracetam (LEV) and BRV in 10 animal models of focal and generalized
epilepsy, indicating that it has broad antiseizure effects. In the rat amygdala kindling model –
a model of drug-resistant focal epilepsy – UCB0942 is superior to 12 other AEDs tested thus 
far: LEV, BRV, phenytoin, phenobarbital, carbamazepine, lacosamide, valproate, retigabine, 
perampanel, clobazam, diazepam, clonazepam, and the combination of LEV or BRV with 
diazepam. In this model of drug-resistant focal epilepsy, UCB0942 was the only compound 
that produced complete seizure suppression in all animals at a plasma exposure equivalent to 
the plasma exposure achieved in humans taking UCB0942 400mg bid. Other AEDs produced
seizure suppression in this model, but only at plasma exposures that are unattainable in 
humans. Based on its superior preclinical efficacy profile, UCB0942 may show efficacy in 
patients with focal epilepsy who continue to suffer from frequent seizures despite having 
attempted to achieve seizure control with multiple AED regimens (patients with highly drug-
resistant focal epilepsy).

If seizure freedom or a substantial reduction in seizure frequency could be achieved in these 
patients, their quality of life would dramatically improve, and this improvement is expected 
to outweigh the potential risks associated with the administration of UCB0942.
Preclinical experience with UCB0942 is described extensively in the Investigator’s Brochure.
2.2
Phase 1 experience
UCB0942 has completed Phase 1 development with a total of 145 subjects exposed to single 
doses up to UCB0942 490mg and multiple doses up to UCB0942 400mg bid for up to 
14 days, including 20 subjects with epilepsy at 400mg bid. There were no clinically
significant changes in laboratory tests or vital signs thought to be related to UCB0942 during 
Phase 1 development, although transient, minor reductions in systolic and diastolic blood 
pressure were seen (consistent with the known effects of benzodiazepine drugs). There were 
no clinically significant changes attributed to UCB0942 in 12-lead ECGs; however, 
4 subjects had treatment-emergent rhythm disturbances (atrial and ventricular ectopy). These 
were asymptomatic and were assessed by an external cardiologist expert in electrophysiology 
as unlikely to be related to UCB0942.
2.2.1
Adverse event profile 
The safety findings to date suggest that the adverse event (AE) profile in subjects receiving 
single and repeated doses of UCB0942 is related mostly to the central nervous system (CNS). 
At UCB0942 300mg bid and above the AEs tend to be of slightly greater severity and 
persistence than at doses below UCB0942 300mg bid. In broad terms, the AEs are consistent 
with the AEs associated with established SV2 and GABA-A targeting AEDs, and common 
CNS AEs include headache, nausea, somnolence, fatigue, dizziness, balance disorder, 
disturbance in attention, and memory impairment. Modeling of the relationship between dose 
or plasma exposure, time, and AEs showed that 1) headache, fatigue, somnolence, balance 
disorder, and disturbance in attention are dose-dependent AEs; 2) tolerance develops for 
disturbance in attention and balance disorder; 3) tolerance does not seem to develop for 
fatigue, somnolence, and headache; and 4) titration will reduce the likelihood that a subject 
experiences most of these AEs. 
2.2.2
Psychiatric adverse events
In the multiple ascending dose study, 1 healthy volunteer had a “delirious syndrome” with 
prominent psychotic symptoms, and in a subsequent Phase 1 study, 1 healthy volunteer had 
“mania-like symptoms.” Both of these AEs were classified as serious adverse events (SAEs)
because the subjects required hospitalization. After these psychiatric SAEs occurred, close 
psychiatric monitoring was implemented. Therefore, when 2 other healthy volunteers began 
to develop “hypomania” and “aggressive state,” respectively, the symptoms were discovered 
early, and discontinuation of UCB0942 prevented the development of these symptoms into 
more severe psychiatric symptoms. Based on this, it appears that close psychiatric monitoring 
during the first 2 weeks of dosing, and tapering and discontinuation of the drug in subjects 
who start to develop psychiatric AEs, will reduce the risk that subjects develop more severe 
psychiatric AEs or psychiatric SAEs. Therefore, in this study, daily psychiatric monitoring 
will be performed in all subjects for the first 2 weeks after dosing starts, and weekly 
thereafter. In addition, to further reduce the risk that participating subjects develop 
psychiatric AEs, subjects with a history of psychosis, schizophrenia, bipolar disorder, or 
severe unipolar depression will be excluded from this study. Lastly, based on the fact that 
titration has been shown to reduce the incidence of other AEs and increase the general 
tolerability of UCB0942, titration may also reduce the risk of psychiatric AEs.

2.2.3
Drug-drug interactions
A drug-drug interaction study in subjects with epilepsy showed that carbamazepine – a strong 
cytochrome P450 (CYP) 3A4 inducer – reduced UCB0942 plasma exposure by >85%. 
Therefore, subjects on carbamazepine or other strong CYP3A4 inducers (eg, phenytoin, 
phenobarbital, or primidone) will not be enrolled in this study because the plasma exposure 
may be too low to produce any therapeutic benefit.
2.3
Rationale for this study
This is a Phase 2A efficacy, safety, and tolerability study.
Based on the preclinical results in 10 animal models of focal and generalized epilepsy, and 
the precedented mechanisms of action, it is almost certain that UCB0942 will have 
antiseizure effects in humans. The rationale for the current study is to test whether UCB0942 
has unprecedented efficacy in a very severe patient population, namely in subjects with focal 
epilepsy who continue to suffer from frequent, almost-daily seizures despite having attempted 
to achieve seizure control with multiple AED regimens. In this study the efficacy of 
UCB0942 400mg bid in subjects with such highly drug-resistant focal epilepsy will be 
assessed for the first time. In this protocol, “focal seizures” refers to partial-onset seizures of 
type IA1, IB, and IC, but does not include type IA2, IA3, or IA4 seizures.
Based on analysis of similar subjects in UCB’s lacosamide and BRV databases, the placebo 
response is very low (after 2 weeks of treatment <7% achieved ≥75% reduction in seizure 
frequency and <2% were seizure free, and after 12 weeks of treatment <4% maintained ≥75% 
reduction in seizure frequency and 0% were seizure free); however, the placebo arm is 
necessary to confirm that the placebo response is equally low in the current target population 
and in the setting of this study (ie, inpatient) and to avoid a false positive study due to an 
apparent seizure frequency reduction from the Prospective Outpatient Baseline Period to the 
Inpatient Treatment Period.

STUDY VARIABLES
4.1
Efficacy variables
4.1.1
Primary efficacy variable
Seizure frequency will be determined using subject diary cards. The subject will be instructed 
as to how to complete the diary, and the procedure for completing the diary will be identical 
during the Outpatient and Inpatient Periods.
The primary outcome measure is the 75%RR. In the active group, this is defined as the 
proportion of subjects with a 75% or greater reduction in focal seizure frequency during the 
last 2 weeks of the Inpatient Period compared to the 2-week Prospective Outpatient Baseline
Period. In the placebo group, the 75%RR is defined as the proportion of subjects with a 75% 
or greater reduction in focal seizure frequency during the first 2 weeks of the Inpatient Period 
(the 2 weeks on placebo) compared to the Prospective Outpatient Baseline Period.
4.1.2
Secondary efficacy variables
The secondary efficacy variables are:
!
Median percent reduction in weekly focal seizure frequency from the Prospective 
Outpatient Baseline Period to the Inpatient Period and the End of Treatment.
!
Seizure-free rate during the Inpatient Period, the last 4 weeks of the Outpatient 
Maintenance Period, and at the End of Treatment.
!
The 75%RR during the last 4 weeks of the Outpatient Maintenance Period and at the End 
of Treatment.
!
Percentage of seizure-free days during the Inpatient and Outpatient Periods.
4.1.3
Exploratory efficacy variables
Exploratory efficacy variables are as follows:
!
Median seizure frequency by seizure type (IA1, IB, IC) per study period: Prospective 
Outpatient Baseline, Titration Inpatient, 1-week Maintenance Inpatient, Transition to 
Outpatient, Outpatient Maintenance, and overall on-treatment period.

!
Blood samples for DNA, mRNA, and lipidomics/proteomics/additional blood biomarkers
will be collected during the study:
∀
DNA: One tube for DNA isolation will be collected at the beginning of the Inpatient 
Period of the study. The DNA may be used to assess known variants associated with 
drug-resistant epilepsy or AED resistance and may be used for further genetic 
analyses relating to epilepsy and drug response.
∀
mRNA: One tube will be collected on the day before the first dose of 
UCB0942/placebo, and 1 tube will be collected on the last day of the Inpatient 
Maintenance-Dose Week. The mRNA samples may be used to identify gene 
expression patterns that are associated with disease etiology, that predict (Baseline 
sample), or that are associated with (posttreatment sample) drug response.
∀
Lipidomics/proteomics/additional blood biomarkers: One tube will be collected on 
the day before the first dose of UCB0942 or placebo, and 1 tube will be collected on 
the last day of the Inpatient Maintenance-Dose Week. These samples may be used for 
additional blood biomarker analysis.
All subjects will be asked to provide specific consent for these samples. Refusal to provide 
consent for the collection of samples for DNA, mRNA, and lipidomics/proteomics will not 
disqualify the subject from participating in the study.
Single archive blood samples (for potential background AED assay) will be collected at the 
start of titration, the end of the Inpatient Period, and at the end of the Outpatient Maintenance 
Period (before last dose of IMP). These samples will be collected just before the morning 
dose of IMP and stored for up to 1 year after the study ends.
!
At the discretion of the Investigator, sites may or may not perform video or 
video-electroencephalogram (EEG) monitoring during parts of the Inpatient Period or 
during the whole Inpatient Period, depending on the infrastructure of each site, to assess 
seizure type, severity, duration, and the duration of the postictal period. The video data 
will not be used to corroborate or supplement the diary data and shall not influence the 
diary seizure capture by the subject.
!
Responses to open questions in the Diary Addendum, including:
∀
Reason for participation in the study
∀
Hopes for this new treatment and fulfillment of hopes during the study
∀
Baseline and change from Baseline in the impact of seizures on the patient’s life
The subject will be instructed to leave any questions blank that he/she does not feel 
comfortable answering.

Safety variables
The safety of participating subjects will be closely monitored. Psychiatric assessment will be 
performed by a staff member trained in the identification of psychiatric symptoms, and the 
assessments will be performed using the Brief Psychiatric Rating Scale (BPRS; Overall and 
Gorham, 1962), which assesses various psychiatric domains including:
!
Changes in mood and symptoms of depression or mania
!
Changes in thinking and perception, and other symptoms of psychosis
!
Changes in behavior
Other safety variables are:
!
Adverse events reported by the subject and/or caregiver or observed by the Investigator or 
inpatient staff
!
Serious adverse events
!
Subject withdrawals or premature UCB0942 tapering due to AEs
!
Changes in clinical laboratory test parameters
!
Changes in vital sign parameters – pulse rate, blood pressure, and respiratory rate
!
Changes in 12-lead electrocardiogram (ECG) parameters
!
Changes in 2-dimensional Doppler echocardiography from Baseline to after Baseline 
(during dosing, after the last dose, and 6 months after last dose), with diastolic 
measurements as well as atrial volumes to identify any subtle valvular changes and to 
assess for pericardial effusions
!
Changes in physical examination (including body weight) and neurological examination 
findings
!
Changes in memory or cognition as assessed with the mini-mental state examination 
(MMSE; Folstein et al, 1975)
!
Changes indicative of a hypersensitivity reaction including an AE or laboratory value (as 
defined below) suggestive of internal organ involvement (including but not limited to 
hepatitis, nephritis, pneumonitis, carditis, colitis, encephalitis, pancreatitis, myositis, 
arthritis, or hematologic system involvement) combined with at least 1 of the following: 
fever, rash, lymphadenopathy, or eosinophilia
∀
Treatment-emergent abnormal laboratory value criteria suggestive of internal organ 
involvement or eosinophilia:
◦
Eosinophils % ≥10%
◦
Eosinophils absolute ≥0.5G/L
◦
Neutrophils absolute <1.5G/L
◦
Platelets ≤100G/L
◦

STUDY DESIGN
5.1
Study description
EP0069 is a Phase 2A, double-blind, randomized, placebo-controlled, multicenter study that 
will test the potential efficacy, safety/tolerability, and PK profile of UCB0942 in adult 
subjects with highly drug-resistant focal epilepsy. UCB0942 400mg bid will be administered 
as add-on to each subject’s concomitant AED regimen.
Screening assessments will be conducted after subjects have understood the risks and 
potential benefits of the study and signed the written Informed Consent form (ICF). Only 
subjects who fulfill all eligibility criteria will be enrolled.
This study consists of:
!
A 4-week prescreening Historical Baseline Period for study eligibility purposes
!
A Screening Visit followed by a 2- to 3-week postscreening Prospective Outpatient 
Baseline Period (Day BL1 to Day BL14-21)
!
A 3-week Inpatient Period, which consists of:
∀
An Inpatient Titration Week (Day T1 to Day T7)
∀
An Inpatient Maintenance-Dose Week (Day MD1 to Day MD7)
∀
An Inpatient Transition-to-Outpatient Week (Day TTO1 to Day TTO7)
!
An open-label Outpatient Maintenance Period of 8 weeks (Day OP1 to Day OP57)
!
A Tapering Period of 2 weeks (Day TOO1 to Day TOO14)
!
A Safety Follow-Up Period of 4 weeks (Day SFU1 to Day SFU28) 
!
An echocardiogram during dosing and after the last dose (the SFU7 echocardiogram). 
The echocardiogram will be repeated at 6 months (±1 month) after the last dose in the 
following subjects:
∀
Subjects who complete this study but do not enter the OLE study
∀
Subjects who withdraw from the Outpatient Period 
∀
Subjects who withdraw from the Inpatient Period and have an abnormal SFU7 
echocardiogram
UCB0942 doses for placebo subjects will be titrated to UCB0942 400mg bid during the 
Inpatient Transition-to-Outpatient Week (Day TTO1 to Day TTO7). After the Inpatient 
Period, all subjects will continue in an open-label Outpatient Maintenance Period and a final 
Tapering Period of 2 weeks (Day TOO1 to Day TOO14). Doses for subjects continuing in the 
OLE study will not be tapered but will follow the schedule of safety and efficacy assessments 
as outlined in the OLE study protocol. Safety follow up will consist of 2 required visits, 1 and 
4 weeks after the last dose of IMP (Day SFU7 and Day SFU28), and 1 optional visit 2 weeks 
after the last dose of IMP (Day SFU14). For details of the study assessments, refer to 
Table 5-4. For a general presentation of the study design refer to Figure 5‒1.

The objective of the Titration Week is to achieve the maximum UCB0942 dose of 400mg bid 
in as many of the subjects randomized to UCB0942 as possible while minimizing tolerability 
issues. During the Titration Week the dose for subjects randomized to UCB0942 will be 
titrated to UCB0942 400mg bid following the schedule in Table 5‒1. The UCB0942 dose 
will be titrated to 400mg bid in a double-blinded fashion (ie, it will also appear that subjects 
randomized to placebo are being titrated). If, in the opinion of the Investigator, the Subject 
will be unable to titrate to the maximum dose of IMP due to intolerance of a lower dose, the 
Investigator should discuss this immediately with the Sponsor Study Physician, unless the 
subject’s condition warrants immediate unblinding, and time does not allow discussion with 
the Sponsor. Unblinding may be required depending on the plan agreed upon by the 
Investigator and Sponsor Study Physician before dose tapering to UCB0942 200mg bid or 
100mg bid. If unblinding reveals that the Subject is randomized to placebo, then further 
dosing with IMP will cease until the Transition-to-Outpatient Week (third week of the 
Inpatient Period), at which time, the Subject will titrate UCB0942 according to Table 5‒1.All 
other assessments will continue as planned.

a In placebo-arm subjects the same schedule is used from Day TTO1 to TTO7.
Maintenance-Dose Week (second week of the Inpatient Period)
If a subject is not tolerating the maximum dose of IMP well during the 
Maintenance-Dose Week such that the Investigator believes a dose reduction is necessary, 
then then the Investigator should contact the Sponsor Study Physician to discuss the situation 
and agree upon a course of action. If a dose reduction is agreed, unblinding will be required. 
If the subject is randomized to UCB0942, the dose can be tapered from UCB0942 400mg bid
to UCB0942 200mg bid. The taper from UCB0942 400mg bid to UCB0942 200mg bid will
occur over 3 days (see Table 5‒2) Dose tapering to UCB0942 100mg bid may also be 
permitted after discussion with the Sponsor’s Study Physician. If it is revealed that the 
Subject is randomized to placebo, then further dosing with IMP will cease until the 
Transition-to-Outpatient Week (third week of the Inpatient Period), at which time, the 
Subject will titrate UCB0942 according to Table 5‒1. All other assessments will continue as 
planned.

titrated to 400mg bid in a double-blinded fashion (ie, it will also appear that subjects 
randomized to UCB0942 are being titrated) following the schedule in Table 5‒1. If, in the

due to intolerance of a lower dose, the Investigator should discuss this with the Sponsor 
Study Physician. Unblinding may be required depending on the plan agreed upon by the 
Investigator and Sponsor Study Physician.
Dosing in the Outpatient Maintenance Period and Tapering Period
During the Outpatient Maintenance Period, Subjects will continue to administer UCB0942 at 
the final Inpatient Period dose. Multiple adjustments (tapering or increase) of the dose are 
allowed during the Outpatient Maintenance Period (minimum 100mg bid and maximum 
400mg bid); however, any change of dose in the Outpatient Maintenance Period should first 
be discussed with the Sponsor Study Physician. 
At the end of the Outpatient Maintenance Period, or at the time a subject is withdrawn from 
the study, UCB0942 will be tapered following the schedule in Table 5‒3. If the subject is not 
taking a dose of UCB0942 other than 400mg bid, then the Investigator should contact the 
Sponsor Study Physician to discuss the appropriate tapering schedule.

In order to provide an ongoing assessment of the safety of subjects as the study progresses, a 
Safety Review Group (SRG) comprising appropriate Sponsor study team members and the 
Investigator(s) at each site will meet regularly to review appropriate safety data (see 
Section 11.1.9).
5.1.1
Study duration per subject
The total duration of the study after Screening is 20 weeks for each subject, including the 
Prospective Outpatient Baseline Period (2 to 3 weeks), the Inpatient Period (3 weeks), the 
Outpatient Period (8 weeks of treatment and 2 weeks of taper), and a SFU Period (4 weeks).
In addition, there is an echocardiography visit at 6 months after the last dose. The total 
duration of exposure to UCB0942 during this study is 13 weeks.
The end of the study is defined as the date of the last visit of the last subject in the study.
5.1.2
Planned number of subjects and sites
Subjects with highly drug-resistant focal epilepsy will be enrolled at 
 sites in order 
to provide 46 evaluable subjects, ie, 46 subjects who complete the Inpatient Period. Subjects 
who drop out before Visit 6 (eg, during the Inpatient Period) for reasons other than safety or 
tolerability will be replaced. First subject, first visit is planned for Q2 2015.

BPRS and MMSE, and by phone, using the BPRS only, on the other days. 
h CIWA-B will be performed before the evening dose on the last day before discharge from the inpatient unit.
i Vital signs include PR, respiratory rate, SBP, and DBP. In addition, at Day T1, MD7, and TTO7 body temperature should be measured; on Day T1 this should 
be prior to first administration of UCB0942. Obtain vital signs and a 12-lead ECG once in the morning, unless otherwise noted. 
j Height at Screening only.
k In addition to the echocardiogram during dosing and after the last dose (SFU7), the echocardiogram will be repeated at 6 months (±1 month) after the last dose 
in the following subjects: 1) Subjects who complete this study but do not enter the OLE study, 2) Subjects who withdraw from the Outpatient Period, and 3)

Subjects who withdraw from the Inpatient Period and have an abnormal SFU7 echocardiogram. Please note that the during dosing time point of Day OP22 for 
the echocardiogram has a time window of ±1 week instead of ±2 days and the Day SFU7 echocardiogram has a time window of ±1 week instead of ±1 day.
l Clinical chemistry, hematology, and urinalysis.
m At the discretion of the Investigator, sites may or may not perform video or video-EEG monitoring during parts of the Inpatient Period or during  the whole 
Inpatient Period.
n Urine or serum pregnancy test.
o Serology to include HIV-1/2Ab, HBsAg, and HCV-Ab.
p The drug screen will include amphetamines, benzodiazepines, barbiturates, cocaine, cannabinoids, methadone, opiates, and alcohol. Use of AED from one of 
the classes mentioned will be allowed if allowed by inclusion and exclusion criteria.
q Randomization on Day T1 before first IMP administration using IRT.
r Obtain blood samples for measurement of plasma concentration of UCB0942 and metabolites on Day MD1 and MD7, at the following times: predose (within 
5min of dosing), then at 0.5h, 1h, 1.5h, 2h, 3h, 4h, 6h, 8h, and 12h postdose. Time windows for postdose samples are as follows: ±5min for the 0.5h, 1h, 1.5h, 
2h, 3h, and 4h samples; ±10min for the 6h, 8h, and 12h samples. The 12h sample must be obtained prior to the pm dose. 
s Obtain blood samples for measurement of trough levels of UCB0942 and metabolites just prior to the morning dose of UCB0942. If a predose sample is not 
possible prior to the morning dose a sample can be taken just prior to the evening dose of UCB0942. If no sample can be taken just prior to dosing, a postdose 
sample will be taken and the actual dosing and sampling times will be recorded. 
t The QOLIE-31-P will be completed by all subjects prior to any other study procedures at the visit. At Day T1, QOLIE-31-P will be assessed in the morning 
before randomization.
u For the Outpatient Period, medication will be dispensed on Days TTO7, OP15, OP29, OP43, and OP57.
v Medication should be presented at each visit for check on compliance.
w During the Baseline Period the subjects should be called at least once to check on the completion of the diary card.
x The subject will be instructed to leave any questions blank that he/she does not feel comfortable answering.
y Collect at Day OP57 or at Early Withdrawal.

Rationale for study design and selection of dose
This multicenter, double-blind, randomized, placebo-controlled, parallel-group study will 
assess the safety and efficacy of UCB0942 in the adjunctive treatment of seizures with or 
without secondary generalization in adult subjects with highly drug-resistant focal epilepsy, 
for the first time. The study will have an Inpatient Period to minimize the psychiatric risk to 
subjects during the titration. The Outpatient Maintenance Period is necessary to ensure that 
any efficacy observed is maintained and that subjects do not develop tolerance to UCB0942.
The dose used in this study (UCB0942 400mg bid) was chosen because it is the maximum
tolerated dose (MTD) in Phase 1 studies. This dose is expected to:
1. achieve exposures similar to those that show unprecedented efficacy in the rat amygdala 
kindling model of drug-resistant focal epilepsy,
2. achieve full and constant SV2 occupancy based on modeling predictions, and
3. achieve 10-15% occupancy of the cBZR site on the GABA-A receptor.
Based on previous experience in Phase 1, a dose titration over 1 week was chosen to 
minimize the occurrence of AEs. The titration will be performed during the Inpatient Period 
in all subjects (Section 8.2.1). If a subject does not tolerate UCB0942 400mg bid during the 
Maintenance-Dose Week or later, taper to UCB0942 200mg bid can be started by the 
Investigator.

SELECTION AND WITHDRAWAL OF SUBJECTS
6.1
Inclusion criteria
To be eligible to participate in this study, all of the following criteria must be met:
1. Subject is an adult (18 years of age or more).
2. Subject is able to understand the study and the ICF as assessed by the Investigator.
Subjects with known mental retardation (defined as IQ below 70) are not eligible to 
participate.
3. A written ICF approved by the or Independent Ethics Committee (IEC) is signed and 
dated by the subject, after the Investigator assesses whether the subject is able to 
understand the potential risks and benefits of participating in the study. A separate ICF 
should be signed and dated by the subject to allow for the optional DNA, mRNA, and 
lipidomics/proteomics/additional blood biomarker samples.
4. Subject and/or caregiver is considered reliable and capable of adhering to the protocol 
(eg, able to understand and complete diaries), visit schedule, and the medication intake 
scheme as instructed according to the judgment of the Investigator.
5. Subject is of normal weight as determined by a body mass index (BMI) between 16.0 and 
40.0kg/m2 (exclusive) and with a body weight of at least 50kg (males) or 45kg (females).

epilepsy in the last 5 years.
∀
the subject has no seizures that are not focal by the new ILAE criteria.
∀
a brain MRI (magnetic resonance imaging) or head CT (computed tomography) to be 
performed before randomization, if no such scan was performed in the last 5 years, 
and a report is available. If a scan was performed within the last 5 years but the 
epilepsy has not been stable since the last scan, a new scan should be obtained.
7. Subject has failed to achieve seizure control with ≥4 appropriately chosen AED regimens 
of adequate dose and duration, including the current treatment, as documented in medical 
records and per Investigator assessment of patient report.
8. Subject is currently treated with a stable dose of at least 1 AED for the 4 weeks prior to

if available). The cut-off seizure frequency (4 seizures per week) and maximum seizure-
free interval (3 days) must be maintained during the 2-week Prospective Outpatient 
Baseline Period.
10. Subject has clinical laboratory test results within the reference ranges of the laboratory or
isolated test results that are outside the specified ranges and that are deemed as not 
clinically significant by the Investigator.
11. Subject has blood pressure and heart rate within normal range in the supine position after 
5 minutes rest, or the subject has hypertension that is under partial control with a stable 
antihypertensive medication regimen but that the Investigator deems as clinically not 
significant.
12. Female subjects of nonchildbearing potential (premenarcheal, postmenopausal for at least 
2 years, bilateral oophorectomy or tubal ligation, and complete hysterectomy) are eligible. 
Female subjects of childbearing potential are eligible if they use medically accepted 
contraceptive methods. Oral or depot contraceptive treatment with at least ethinylestradiol 
30μg per intake used with an additional barrier contraception method, monogamous 
relationship with vasectomized or female partner, or double-barrier contraception are 
acceptable methods. The subject must understand the consequences and potential risks of 
inadequately protected sexual activity, be educated about and understand the proper use 
of contraceptive methods, and undertake to inform the Investigator of any potential 
change in status. Abstinence will be considered as an acceptable method of contraception 
if the Investigator can document that the subject agrees to be compliant when it is in line 
with the preferred and usual lifestyle of the subject.
13. Male subjects confirm that during the study period and for a period of 3 months after the 
final dose, when having sexual intercourse with a woman of childbearing potential, he 
will use a barrier contraceptive (eg, condom) and that the respective partner will use an 
additional contraceptive method.
6.2
Exclusion criteria
Subjects are not permitted to enroll in the study if any of the following criteria is met:

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 Case Report form (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.
3. Subject has a known hypersensitivity to any components of UCB0942 formulation or to 
similar drugs (LEV, BRV, or benzodiazepines), or a history of drug or other allergy that, 
in the opinion of the Investigator or UCB Study Physician, contraindicates her/his 
participation.
4. Subject has had significant blood loss or has donated or received 1 or more units (450mL) 
of blood within 30 days prior to UCB0942 administration, or has donated plasma or 
platelets within 14 days prior to UCB0942 administration for this study.
5. Subject tests positive for human immunodeficiency virus-1/2 antibody (HIV-1/2Ab), 
hepatitis B surface antigen (HBsAg), or hepatitis C antibody (HCV-Ab).

or would compromise the subject’s safety or his/her ability to participate in this study.
7. Subject has a current or past psychiatric condition that, in the opinion of the Investigator, 
could compromise his/her safety or ability to participate in this study including a history 
of schizophrenia, schizoaffective disorder, bipolar disorder, or severe unipolar depression. 
The presence of potential psychiatric exclusion criteria will be determined based on
screening with the BPRS plus the Mini International Neuropsychiatric Interview (MINI).
8. Subject has a history of status epilepticus or has been hospitalized for status epilepticus 
within the 6-month period prior to Screening Visit.
9. Subject has had EEGs showing a pattern not consistent with a diagnosis of focal epilepsy 
(eg, generalized spike-wave).
10. Subject only has seizures that are uncountable due to clustering.
11. Subject has had pseudoseizures, conversion disorder, or other nonepileptic ictal events 
that, in the opinion of the Investigator, could be confused with seizures.
12. Subject had epilepsy surgery <1 year or an epilepsy dietary therapy initiated < 3 months 
prior to Screening.
13. Subject has taken other (non-AED) prescription, nonprescription, dietary (eg, grapefruit 
or passion fruit), or herbal products that are potent inducers or inhibitors of the CYP3A4 
pathway for 2 weeks (or 5 half-lives, whichever is longer) prior to the Baseline Visit.
14. Subject is currently treated with carbamazepine, phenytoin, primidone, or phenobarbital 
or any other drug known as a strong inducer of CYP3A4 liver enzymes.
15. Subject is taking tiagabine, felbamate, or vigabatrin.

18. Subject has past or present substance abuse/dependence that in the opinion of the 
Investigator could threaten the subject’s safety within the study, affect the subject’s 
ability to fully participate in the study, or confound study interpretation.
19. Subject has a lifetime history of suicide attempt (including an actual attempt, interrupted 
attempt, or aborted attempt), or has suicidal ideation in the past 6 months as indicated by 
a positive response (Yes) to either Question 4 or Question 5 of the C-SSRS at Screening.
20. Subject has a clinically significant abnormality on ECG that, in the opinion of the 
Investigator, increases the risks associated with participating in the study. In addition, any 
subject with any of the following findings will be excluded:
∀
QT corrected for heart rate using Bazett’s formula (QTcB) or QT corrected for heart 
rate using Fridericia’s formula (QTcF) interval >450ms
∀
Bundle branch blocks and other conduction abnormalities that are clinically 
significant according to the Investigator and/or with a PR interval ≥220ms
∀
Irregular rhythms other than sinus arrhythmia or occasional, rare supraventricular or 
rare ventricular ectopic beats
∀
In the judgment of the Investigator, T-wave configurations are not of sufficient 
quality for assessing QT interval duration.
21. Subject has a history of unexplained syncope or a family history of sudden death due to 
long QT syndrome.
22. Subject has a clinically significant abnormality on echocardiography at Screening or a 
history of rheumatic heart disease or other known valvular abnormalities.
23. Subjects with a history of hypersensitivity reactions or autoimmune disease.
24. Female subject who is pregnant or breastfeeding.
6.3
Withdrawal criteria
Subjects are free to withdraw from the study at any time, without prejudice to their continued 
care.
Subject may be withdrawn by the Investigator if s/he is noncompliant with the study 
procedures or medications in a way that, in the opinion of the Investigator, may affect the 
study or the safety of the subject, or a subject is unable to manage the completion of the 
diary, or demonstrates a questionable diary.
Subjects must be withdrawn from the study if any of the following events occur:
1. Subject develops a clinically relevant medical condition (or laboratory abnormality) that, 
in the opinion of the Investigator, compromises the subject’s ability to participate or 
safety. Potential drug-induced liver injury IMP discontinuation criteria are described in 
Section 6.3.1. To monitor for hypersensitivity reactions, percent eosinophils >10% or 
absolute eosinophil count ≥0.5G/L or absolute neutrophil count <1.5G/L or absolute 
platelet count ≤100G/L, if in combination with fever, rash, lymphadenopathy, or other 
symptoms/signs suggestive of internal organ involvement (including but not limited to 
hepatitis, nephritis, pneumonitis, carditis, colitis, encephalitis, pancreatitis, myositis, or 
arthritis) will lead to stopping the IMP.
2. UCB or a regulatory agency requests withdrawal of the subject.

4. Subject requires treatment with a medication that is not permitted (Section 7.8.2) and is 
not allowed after discussion with the UCB Study Physician.
5. Subject becomes pregnant.
6. Subject has active suicidal ideation without specific plan as indicated by a positive 
response (“Yes”) to Question 4 of the “Since Last Visit” version of the 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. If the Subject has active suicidal 
ideation with a plan as indicated by a positive response (“Yes”) to Question 5 of the 
“Since Last Visit” version of the C-SSRS, the subject should be referred immediately to a 
Mental Healthcare Professional and must be withdrawn from the study.
7. Subject has a prolongation or worsening of overall seizure duration, frequency, type, or 
pattern considered by the Investigator as persistent and serious enough to warrant 
discontinuation from the study.
In the case of withdrawal or discontinuation during the study or during the echocardiography 
follow-up period, the Investigator should attempt to obtain information on subjects. For 
subjects considered as 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 electronic Case Report form (eCRF) must document the primary 
reason for withdrawal or discontinuation.
The Investigator should contact the UCB Study Physician whenever possible to discuss the 
withdrawal of a subject in advance. If this is not possible, the Investigator should contact the
UCB study physician to inform him/her about the subject withdrawal as soon as possible after 
the withdrawal.

6.3.1
Potential drug-induced liver injury IMP discontinuation criteria
Subjects with potential drug-induced liver injury (PDILI) must be assessed to determine if 
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%).
If a nondrug-related cause for the symptoms can be confirmed, these subjects may resume 
IMP administration after discussion with the responsible UCB physician, but only when the 
requirements for rechallenge with IMP as provided in Section 11.6.1.2.1 are followed.
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).
Evaluation of PDILI must be initiated as described in Section 11.6.1. If subjects are unable to 
comply with the applicable monitoring schedule, IMP must be discontinued immediately.
Investigators should attempt to obtain information on subjects in the case of IMP 
discontinuation to complete the final evaluation. Subjects with PDILI should not be 
withdrawn from the study until investigation and monitoring are complete. All results of 
these evaluations and observations, as well as the reason(s) for IMP discontinuation and 
subject withdrawal (if applicable), must be recorded in the source documents. The CRF must 
document the primary reason for IMP discontinuation.

bottles, with a 2-week supply (see Table 5-4). For the Taper Period, bottles of 100mg tablets 
will be dispensed for 1-2 weeks, depending on dose from which the taper starts.
7.4
Labeling
Clinical drug supplies will be labeled in accordance with the current International Conference 
on Harmonisation (ICH) guidelines on Good Clinical Practice (GCP) and Good 
Manufacturing Practice (GMP) and will include any locally required statements. If necessary, 
labels will be translated into the local language.
7.5
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.
Appropriate room temperature storage conditions must be demonstrated by completion of a 
temperature log in accordance with local requirements, including the capture of minimum 
and maximum temperatures reached over a time interval. Temperatures, including minimum 
and maximum recordings, should be documented daily on the log during the site’s days of 
operation. The IMP is to be stored according to the instructions on the label.
In case an out-of-range temperature is noted, it must be immediately communicated to the 
Exploratory Project Manager (EPM) (or designee) before further use of the IMP.
The EPM (or designee) will transmit the out-of-range temperature (copy of the temperature 
log and duration of the out-of-range temperature, if available) to the Drug Supply 
Coordinator. Based on discussion with a UCB Quality Assurance representative, the Drug 
Supply Coordinator will then provide the EPM (or designee) with instructions for the site 
regarding use of the IMP.
The Investigator (or designee) will instruct the subject to store the IMP following the 
instructions on the label.
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 (due to breakage or wastage), not 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.
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) and unused IMP containers must be reconciled and returned to UCB (or 
designee), preferably in their original package. Investigational medicinal product intended for 
the study cannot be used for any other purpose than that described in this protocol.

Procedures for monitoring subject compliance
At each visit after where new IMP is dispensed and at the end of the Taper Period (Days 
OP15, OP29, OP43, OP57, and TOO14), subjects must return all unused IMP and empty IMP 
containers. Subjects will be asked to document drug intake on the subject diary throughout 
the Treatment Period. 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.
If a subject is found to be persistently noncompliant (defined as less than 75% or more than 
125% compliant with the dosage schedule), the Sponsor, in conjunction with the Investigator, 
will make a decision as to whether the subject should be withdrawn from the study.
Timely completion of the subject diary is essential for evaluation of safety and efficacy. A 
caregiver is allowed to help the subject with the completion of the subject diary. Subject diary 
completion will be evaluated at each visit.

Blinding
This is a study with a double-blind Inpatient Period and an open-label Outpatient Period. At 
the start of the Titration Period (Day T1) subjects will be randomized to UCB0942 400mg 
bid or placebo in a 1:1 ratio.
The randomization will be stratified for the following LEV prior/current use factor to ensure 
the balance across treatment groups (Placebo, UCB0942 400mg bid):
!
use of LEV (3 levels):
1. LEV prior and current use (concomitant use of LEV at study entry)
2. LEV Prior Use Only=History of prior LEV use and must have discontinued 
4 weeks prior to study entry
3. LEV Naïve=No history of prior LEV use, and no use at study entry
7.9.1
Procedures for maintaining and breaking the treatment blind
7.9.1.1
Maintenance of study treatment blind
All subject treatment details will be allocated and maintained by the interactive response 
technology (IRT). Details of the IRT system will be addressed in a separate randomization 
schedule specification document.
7.9.1.2
Breaking the treatment blind in an emergency situation
In the event of an emergency, it will be possible to determine which treatment arm and dose 
the subject has been allocated to by contacting the IRT. All sites will be provided with details 
of how to contact the system for code breaking at the start of the study. The Medical Monitor 
or equivalent should be consulted prior to unblinding, whenever possible.
The EPM will be informed immediately via the IRT when a code is broken, but will remain 
blinded to specific treatment information. Any unblinding of the IMP performed by the 
Investigator must be recorded in the source documents and on the Study Termination eCRF 
page.
The SRG may also elect to break the blind for individual subjects as part of its review 
process, in order to better assess the significance and response to AEs of concern (see 
Section 11.1.9).
7.9.1.3
Breaking the treatment blind for taper of dose during the study
When the Investigator and Sponsor Study Physician agree that a subject cannot titrate to the 
maximum dose or that a dose reduction is necessary during the Inpatient Period (See 
Section 5.1, the blind will have to be broken, following the procedure described in Section 
7.9.1.2.
7.10
Randomization and numbering of subjects
An IRT will be used for assigning eligible subjects to a treatment regimen based on a 
predetermined production randomization and/or packaging schedule provided by the IRT 
vendor. The randomization schedule will be produced by the IRT vendor. The IRT will 
generate individual assignments for subject kits of study drug, as appropriate, according to 
the visit schedule.
To enroll a subject (Visit 1), 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. 
To randomize a subject (Visit 3), the Investigator or designee will contact the IRT and 
provide brief details about the subject to be randomized. The IRT will automatically inform 
the Investigator or designee of the subject’s randomization number. The IRT will allocate kit 
numbers to the subject based on the subject number during the course of the study.
After completion of the Inpatient Maintenance Period, doses for subjects receiving placebo 
will be titrated to the Outpatient Maintenance Dose (Day TTO 1 to TTO7). To ensure 
continued blinding all subjects will remain in the clinic for this titration period.

Baseline Period (Visit 2, Day BL1 to BL14-21)
The Baseline Period (Day BL1 to BL14-21) will commence the day after the first day of 
Screening and will start no more than 3 weeks before entry into the clinic for the Inpatient 
Period. 
During the Baseline Period a phone call will be made to the subject to verify completion of 
the diary card and to confirm the T1 admission day.
Screening assessments that cannot be completed on the first screening visit (eg, brain imaging 
with MRI or CT and echocardiogram) can be performed at any time during the Baseline 
Period but must be completed before the first dose of UCB0942.
If a subject fails screening, a rescreening is allowed if deemed appropriate by the 
Investigator.

Randomization (after all assessments have been done)
Subjects randomized to the active group will be titrated up to UCB0942 400mg bid over 
1 week, as shown in Table 5‒1. Subjects randomized to placebo will do a dummy titration. 
After all admission assessments have been completed, all subjects will be given their first 
100mg dose of IMP (or placebo) in the evening under medical supervision. During the 
double-blind part of the study, subjects in both arms will take the same number of tablets. All 
subjects will continue to record their seizures in subject diaries during the Titration Week.

Transition-to-Outpatient Week (Visit 5, Day TTO1 to Day TTO7)
After the end of the Maintenance-Dose Week, subjects will continue to take IMP if this is 
well tolerated (as determined by the Investigator and the subject). If a subject in the active 
arm is not tolerating UCB0942 400mg bid well during the Maintenance-Dose Week, the dose 
can be tapered to UCB0942 200mg bid during the Transition-to-Outpatient Week before 
discharge to the Outpatient Maintenance Period. In this case, the blind will be broken. The 
taper from UCB0942 400mg bid to UCB0942 200mg bid would occur over 3 days (see 
Table 5‒2).
UCB0942 doses for subjects in the placebo arm will be titrated to UCB0942 400mg bid in the 
same way as the doses for subjects in the active arm were titrated during the Titration Week 
(Table 5‒1). If UCB0942 is well tolerated during the titration, subjects in the placebo arm 
will be discharged on UCB0942 400mg bid and followed in the Outpatient Maintenance 
Period. If a subject in the placebo arm cannot tolerate the titration up to UCB0942 400mg

The entire Inpatient Period will be double-blind (except in cases in which the dose needs to 
be reduced or the taper cannot be completed, as described above); however, subjects and staff 
will know that at discharge all subjects are taking active compound. Therefore, the Outpatient

subject does not tolerate UCB0942 400mg bid, the Investigator can decide to taper to 
UCB0942 200mg bid as shown in Table 5‒2. During the first week of the Outpatient 
Maintenance Period, all subjects will undergo psychiatric monitoring by phone on the days 
they do not visit the clinic (Days OP1, OP2, OP4, OP6, and OP7) and in person in the clinic 
on Days OP3, OP5, and OP8. Cognitive monitoring with MMSE will take place in the clinic 
on Days OP3, OP5, and OP8. This monitoring is necessary because the subjects initially 
randomized to placebo will be discharged directly after the titration to UCB0942 400mg bid
and psychiatric AEs are most likely to occur in the first 2 weeks of UCB0942 administration.
During the Outpatient Maintenance Period subjects will visit the clinic on the following days 
(±2 days to allow for weekend interruptions):
Day OP3, OP5, OP8, OP15, OP22, OP29, OP36, OP43, OP50, and OP57.
When possible, outpatient clinic visit days will take place in the morning to allow dosing to 
take place in the clinic and collection of a predose blood sample for evaluation of trough PK 
levels at specific visits.
Dose tapering from UCB0942 400mg bid to UCB0942 200mg bid to increase tolerability 
may be implemented for each subject at any time during the 8 weeks of treatment in the 
Outpatient Maintenance Period at the discretion of the Investigator in conjunction with the 
wishes of the subject. Dose tapering to UCB0942 100mg bid may be permitted after 
discussion with the Sponsor’s Study Physician.
During this period the following assessments will be performed according to the schedule of 
assessments (Table 5-4):

All subjects who do not continue into the OLE study (see Section 8.6) will undergo a Taper 
and Safety Follow-Up Period to taper off study medication over a 2-week period (Table 5‒3). 
Subjects will start their taper on Day OP57 (Visit 15) and will return for the Mid Taper Visit 
(Day TOO7) after 1 week and for the End of Taper Visit (Day TOO14) after 2 weeks. 
Changes to concomitant AED(s) are allowed during taper of UCB0942. Subjects can also 
start this taper earlier during the Outpatient Maintenance Period, if they decide to exit the 
study early.
During this period the following assessments will be performed as outlined in the schedule of 
assessments (Table 5-4):
!
Return and dispense of diary cards at each visit
!
Withdrawal criteria will be assessed at each visit
!
Administration of IMP

Echocardiography follow up
For subjects who complete this study but do not continue in the OLE study, it is mandatory 
that they have an echocardiogram at 6 months (±1 month) after the last dose of IMP (in 
addition to the echocardiogram at Screening, during dosing, and after the last dose). 
8.4
Withdrawal Visit
In case of early withdrawal of the subject for any reason, all efforts should be taken to have a 
safety follow-up visit as described in Section 8.3.3.
If a complete SFU is not feasible, at least the following assessments will be performed:

Unscheduled Visit
At any time, the subject may have an unscheduled clinic visit/phone call if the Investigator or 
the subject deems it necessary.
During an Unscheduled Visit the assessments will be performed as applicable as judged by 
the Investigator
8.6
Open-label extension study (EP0073)
Subjects who experience substantial benefit from UCB0942 with acceptable tolerability may 
have the option to continue taking UCB0942 during an OLE study. The decision to enter the 
OLE study must be made by the subject in consultation with the Investigator and/or the 
subject’s caregiver. This decision must take into account the benefit experienced, the 
potential risks of long-term exposure to UCB0942, and the potential benefit and risks of other 
treatment options available. Subjects who enter the OLE study will have echocardiographic 
follow up as scheduled in the OLE study protocol and will therefore not participate in the
echocardiographic follow up described in Section 8.3.4.

ASSESSMENT OF EFFICACY
The efficacy variables are described in detail in Section 4.1.
9.1
Seizure frequency
At the Screening Visit, seizure count will be based on Investigator assessment of subjects’ 
reports during the 4 weeks prior to the Screening Visit, which will determine the subject’s
eligibility for the study. The minimum required historic seizure count during the 4 weeks

prior to Screening is 4 partial-onset seizures (IA1, IB, or IC according to the International 
Classification of Epileptic Seizures, 1981) per week on average with no seizure-free period 
longer than 3 days (based on Investigator assessment of subject report). During the study, 
subjects will keep diaries to record daily seizure activity from the Screening Visit until the 
end of study participation. Subjects should be reminded to bring their diaries with them to 
each clinic visit. 
The written information will be discussed with the subjects at each visit in order to ensure 
completeness and accuracy. As a result of the discussion, the Investigator will assess the 
seizures according to the ILAE codes and record the seizure types and frequency in the 
eCRF; he/she will also confirm the presence of AEs if applicable.
Subjects should be educated to complete their diary entries after each seizure or at least once 
a day (eg, when taking evening tablets). A caregiver can assist in completing the diary if 
necessary. Substantial noncompliance with diary completion (seizure recording) may result in 
subject discontinuation from the study at any time by the Investigator or the Sponsor; see 
Section 6.3.
The following seizure information will be recorded in the diary:
!
Seizure type
!
Seizure frequency
9.1.1
Video monitoring
At the discretion of the Investigator, sites may or may not perform video or video-EEG 
monitoring during part of the Inpatient Period or during the whole Inpatient Period,
depending on the infrastructure of each site, to allow exploratory analysis of seizure type, 
severity, and duration, and of the duration of the postictal period.
9.2
Seizure Severity Questionnaire
The SSQ (Cramer et al, 2002) is a review of various aspects of seizures. The person who has 
seizures may ask people who have observed the seizures (family, friends) to help answer 
some of the questions asking about events, but not about feelings. There are 10 questions in 3
sections asking about events before, during, and after typical seizures.
The subject should describe their most common type of seizure when answering the 
questions. If subjects are unsure about how to answer a question, they should give the best 
answer they can and write a comment or explanation on the side of the page. 
The Baseline SSQ will be completed according to the tabular schedule of study procedures, 
Table 5-4. The Baseline version of the SSQ will be used for all visits during which the SSQ is 
to be completed. For this study the recall period will be set to 1 week rather than the original 
4 weeks. At the very beginning of the visit, the SSQ will be provided to all subjects. The 
subject will be asked to complete the questionnaire on his/her own. Once completed, the 
subject will return the completed questionnaire to the Investigator or designee, who will 
verify that all questions have been answered. Further details about the SSQ will be covered in 
the Study Manual.
9.3
Quality of Life Inventory in Epilepsy-31-P
The QOLIE-31-P assesses subject functioning and health-related quality of life.
The QOLIE-31-P (Cramer et al, 2003) is an adaptation of the original QOLIE-31 instrument 
(Cramer et al, 1998) that includes 30 items grouped into 7 multi-item subscales (Seizure

In addition to the 31 items of the QOLIE-31, the QOLIE-31-P contains 7 items assessing the 
degree of “distress” associated with the topic of each subscale (ie, distress items) and 1 item 
asking about the relative importance of each subscale topic (ie, prioritization item).
The QOLIE-31-P will be completed according to the tabular schedule of study procedures in
Table 5-4. At the very beginning of the visit, the QOLIE-31-P will be provided to all 
subjects. The subject will be asked to complete the questionnaire on his/her own. Once 
completed, the subject will return the completed questionnaire to the Investigator or designee, 
who will verify that all questions have been answered. Further details about the QOLIE-31-P 
will be covered in the Study Manual.
9.4
Diary Addendum
A Diary Addendum will be completed according to the tabular schedule of study procedures 
in Table 5-4 as well as at the Withdrawal Visit, if applicable. The Diary Addendum will 
consist of a series of open-ended questions including the following: 
!
Why did you agree to take part in this study? 
!
What are your hopes for this new treatment? 
!
What are the biggest impacts of seizures on your life currently? 
!
What was your experience like during the study?
!
Did participating in the study fulfill any of the hopes you had going into the study? 
!
How do you describe the impact of seizures on your life now? Has that changed since the 
beginning of the study? 
Subjects will be instructed to leave any question blank that he/she does not feel comfortable 
answering.

ASSESSMENT OF PK AND EXPLORATORY VARIABLES
10.1
Pharmacokinetic parameters
The PK variables are described in detail in Section 4.2. Calculations of PK parameters will be 
made with Phoenix WinNonlin (version 6.2 or higher) using the actual sampling times and 
are described in Section 13.4.2. The linear trapezoidal method will be used to calculate the 
AUC parameters. 
Detailed information on the collection, storage, preparation, and shipping of samples will be 
presented in a Laboratory Manual.
10.2
Exploratory parameters
Detailed information on the collection, storage, preparation, and shipping of samples for 
DNA, mRNA, lipidomics, and proteomics analysis will be presented in a Laboratory Manual.
Results for the exploratory parameters obtained from DNA, mRNA, lipidomics, and 
proteomics analysis will be described in a separate report.

Sampling procedures
Blood samples for PK and exploratory variables will be obtained at the scheduled time points 
presented in Table 5-4.
Times for PK samplings will be taken with respect to the time of the morning UCB0942 dose 
on the first and last day of the Maintenance-Dose Week, taken as Time 0=0h. Exact sampling 
times will be recorded in the eCRF. 
Predose blood samples for levels of UCB0942 and its major metabolites will be obtained 
after ECGs and vital signs but prior to dosing of the study medication at Visit 4 and Visit 5.
Predose (trough) blood samples for levels of UCB0942 and its major metabolites will be 
obtained at Visits 6 to 15. The Investigator and the subject should make a realistic effort to 
plan the visits during the Outpatient Maintenance Period before the morning or the evening 
dose of UCB0942. If a predose blood sample is not feasible for a specific visit, a postdose 
blood sample should be collected and the actual times of the dosing and sampling recorded.
For the exploratory assessments, the processing of the blood samples will be described in the 
Laboratory Manual. One sample each will be collected for the mRNA, lipidomics, and 
proteomics assay.
For the AED archival samples, processing will be described in the Laboratory Manual.
Preprinted labels will be provided by the analytical laboratory of UCB. Laboratory kits will 
be provided by UCB or a delegate.
10.4
Bioanalytical methods
Plasma concentrations of UCB0942 and metabolites 
 
 will be determined using validated bioanalytical methods.
10.5
Pharmacokinetic/pharmacodynamic relationships 
If appropriate, a population PK analysis will be performed, as described in Section 13.4.2.
If needed, exploratory exposure-response analysis will be performed to describe the 
relationship between the exposure to UCB0942 and the efficacy and/or safety variables.
11
ASSESSMENT OF SAFETY
11.1
Adverse events
11.1.1
Definition of 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 Informed Consent form), including any pretreatment and 
posttreatment periods required by the protocol, ie, through the end of the Taper/Safety 
Follow-up Period, must be reported in the eCRF 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.

Page 57 of 125
Signs or symptoms of the condition/disease for which the investigational product is being 
studied (ie, seizures) 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.
11.1.2
Procedures for reporting and recording adverse events
The subject 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.
11.1.3
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 eCRF 
and source documents should be consistent. Any discrepancies between the subject’s 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 Adverse Event eCRF (including judgment of relationship to 
IMP) are described in the eCRF Completion Guidelines.
11.1.4
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.
If an AE is ongoing at the end of the Taper/Safety Follow-up Period, 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.
Adverse events should not be recorded in the eCRF after the end of the Taper/Safety Follow-
up Period.
11.1.5
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
11.1.6
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 Drug Safety (DS) 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 return for an early discontinuation visit.
!
The subject should immediately stop the intake of the IMP or be tapered as instructed at 
the early discontinuation visit. 
!
A Safety Follow-Up Visit should be scheduled 1 week after the subject has discontinued 
her IMP.
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 DS 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 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 DS department (for contact details see Serious Adverse Event 
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 DS 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.
11.1.7
Overdose of investigational medicinal product
Excessive dosing (beyond that prescribed in the protocol and including overdose) should be 
recorded in the Drug Accountability or Study Drug Dosing module of the eCRF. 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).
11.1.8
Safety signal detection
Appropriate data from the study will be reviewed on an ongoing basis to detect as early as 
possible any safety concern(s) related to the IMP so that Investigators, clinical study subjects, 
regulatory authorities, and IECs will be informed appropriately and as early as possible.

The Study Physician or medically qualified designee/equivalent will conduct an ongoing 
review of AEs and (especially) any SAEs and perform ongoing SAE reconciliations in 
collaboration with the DS representative.
In addition, the SRG will conduct scheduled reviews of appropriate study data for the 
purpose of safety signal detection.
11.1.9
Safety Review Group
An SRG will be established prior to the start of the study, which will comprise, at a 
minimum, the Study Physician(s), clinical pharmacologist, DS representative, biostatistician,
Coordinating Investigator, and the 
 local Coordinating Investigator, with the intention 
of protecting the safety, health, and well-being of each participating subject. Individual 
Principal Investigators (PI, or their delegate) for each participating site will be invited when 
required. The precise membership, scope, and responsibilities of the SRG are described in the 
SRG Charter. 
The SRG will meet once the first 4 subjects have completed the Transition-to-Outpatient 
Week (Visit 6) or withdrawn from the study before Visit 6. Subsequent meetings will occur 
when the first 10 subjects, the first 16 subjects, and the first 22 subjects have completed 
Visit 6 or withdrawn from the study before Visit 6. Thereafter, SRG meetings will be held on 
an as required/ad hoc basis, in response to emerging data, and at the request of any member 
of the SRG.
The SRG will remain blinded through the first database lock (see Section 12.3.3) unless 
emergent safety information requires unblinding of individual drug allocation for optimal 
assessment and response to AEs of concern. At the time of the first database lock, the Study 
Physician(s), clinical pharmacologist, DS representative, biostatistician, and other UCB 
personnel will be unblinded as to all subjects’ treatment allocation at the beginning of the 
Inpatient Period. 
11.2
Serious adverse events
11.2.1
Definition of serious adverse event
Once it is determined that a subject experienced an AE, the seriousness of the AE must be 
determined. An 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 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, except if an extension 
of the Inpatient Period is required to adjust the dose of UCB0942 before discharge
(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.)
11.2.2
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.
11.2.3
Follow up of serious adverse events
An SAE 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. 
Information on SAEs obtained after clinical database lock will be captured through the DS 
database without limitation of time.
11.3
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.
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.
11.4
Immediate reporting of adverse events
The following AEs must be reported immediately:
!
SAE: AE that the Investigator classifies as serious by the above definitions regardless of 
causality
!
Suspected transmission of an infectious agent via a medicinal product
11.5
Anticipated serious adverse events
The following list of Anticipated SAEs has been identified, as these SAEs are anticipated to 
occur in the epilepsy population at some frequency that is independent of drug exposure. This 
original list will remain in effect for the duration of the protocol.
This list does not change the Investigator’s obligation to report all SAEs (including 
Anticipated SAEs) as detailed in Section 11.2.2.

Evaluation of PDILI
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 11.3), and, if applicable, also 
reported as an SAE (see Section 11.1.1).
Evaluation of PDILI consists of the diagnostic testing and continued monitoring included in

consultation with a local hepatologist (if applicable; discussed in Section 11.6.1.1). 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 11.6.1.4). 
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.
When IMP is stopped due to PDILI (as described in Section 6.3.1), IMP must be permanently 
discontinued unless a subsequent alternative diagnosis fully explains the hepatic findings. If a 
subsequent alternative diagnosis fully explains the hepatic findings, and the requirements 
provided in Section 11.6.1.2.1 are met, rechallenge with IMP may be appropriate. 
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.

11.6.1.1
Consultation with the 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 11.6.1.3) and SAE report (if 
applicable).
11.6.1.2
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 11‒3 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 for medically necessary concomitant medication and consider changing any 
medically required concomitant medication known to be hepatotoxic to a suitable alternative.
11.6.1.2.1
IMP restart/rechallenge (if applicable)
Rechallenge with a substance potentially causing drug-induced liver injury is dangerous, may 
be fatal, and must not occur.
Subjects who are immediately discontinued from IMP due to having met certain criteria for 
PDILI (as described in Section 6.3.1 and Table 11‒3), but for whom an alternative diagnosis 
is confirmed, can rarely restart IMP. Rechallenge with IMP can occur only if ALL of the 
following requirements are met:
!
The results of additional testing and monitoring described in Section 11.6.1.3 and 
Section 11.6.1.4 confirm a nondrug-related cause for the abnormal hepatic laboratory 
parameters and any associated symptoms (ie, a subsequent alternative diagnosis fully 
explains the hepatic findings). 
!
No alternative treatment options are available to the subject.
!
The subject has shown clear therapeutic benefit from the IMP.
!
Subject’s ALT or AST elevations do not exceed ≥3xULN.
!
Subject’s total bilirubin is <1.5xULN.
!
Subject has no signs or symptoms of hypersensitivity. 
!
The rechallenge is approved by the UCB responsible physician and a hepatologist. The 
hepatologist must be external to UCB. It is recommended that the hepatologist be a local 
hepatology expert or the hepatologist treating the subject.
!
Subject agrees to the investigator-recommended monitoring plan.
11.6.1.3
Testing: identification/exclusion of alternative etiology

11.6.1.4
Follow-up evaluation
Potential drug-induced liver injury events require follow-up and monitoring as described in 
Table 11‒3. Monitoring should continue until liver chemistry values normalize, stabilize, or 
return to baseline. Determination of stabilization is at the discretion of the investigator in 
consultation with the hepatologist (as applicable) and UCB responsible physician, as needed.
11.7
Other safety measurements
11.7.1
Vital signs
Vital signs including pulse rate, systolic BP, diastolic BP, respiratory rate, and body 
temperature (Day T1 before UCB0942 administration) will be measured in supine position, 
after 5 minutes of rest. Any clinically significant abnormality in the view of the Investigator
will be recorded as an AE.
Vital signs will be measured at the scheduled time points presented in Table 5-4.
11.7.2
Electrocardiograms
All ECG recordings will be performed with the subject resting in the supine position for at 
least 5 minutes. The 12-lead ECG recordings will be measured at the scheduled time points 
presented in Table 5-4. ECG will be recorded at a speed of 25mm/s and with a calibration of 
1cm/mV.

The Investigator should review all ECG recordings and, if there are abnormalities that are 
considered clinically significant for a particular subject, then the Investigator should initiate a 
review by a specialist of all ECG data pertaining to that subject. The following ECG 
parameters will be recorded in the eCRF: heart rate, PR-interval, QRS-duration, QT-interval, 
QTcB or QTcF, and Investigator’s conclusion on ECG profile.
11.7.3
Echocardiograms
Echocardiograms will be performed during Screening, during dosing (Day OP22 ±1 week), 
and after the last dose of IMP (SFU7), as described in Table 5-4. The echocardiogram will be 
repeated at 6 months (±1 month) after the last dose in the following subjects: 
!
Subjects who complete this study but do not enter the OLE study
!
Subjects who withdraw from the Outpatient Period 
!
Subjects who withdraw from the Inpatient Period and have an abnormal SFU7 
echocardiogram
2D Doppler echocardiography will be performed with:
1. Diastolic measurements (mitral forward flow E and A waves and deceleration time)
2. Tissue Doppler on medial and lateral mitral valve annulus (S, E, and A waves)
3. Standardized views for left atrial volume measurements
Images will be recorded and stored digitally and retained if further analysis is needed. A 
complete echocardiography manual will be provided.
11.7.4
Physical examination
Physical examinations will be performed at the scheduled time points presented in Table 5-4. 
The physical examination will include general appearance; ear, nose, and throat; eyes, hair, 
and skin; respiratory; cardiovascular; gastrointestinal; musculoskeletal; hepatic; neurological 
(including limb reflexes); and mental status. Findings that are considered clinically 
significant changes since the physical examination at the Screening Visit will be recorded as 
AEs.
In addition, height will be measured at the Screening Visit with the subject not wearing shoes 
and the outcome will be rounded to the nearest 0.5cm. Body weight will be measured at the 
scheduled time points presented in Table 5-4 . Body weight will be measured with the subject 
in underwear or light clothing and without wearing shoes; the outcome will be rounded to the 
nearest 0.1kg. At the Screening Visit, the BMI will be calculated (weight [kg]/[height (m)]²) 
and will be reported to 1 decimal place.
11.7.5
Assessment of suicidality
Suicidality will be assessed by trained study personnel using the C-SSRS (Posner et al, 2011). 
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 procedures (Section 5.2). The Investigator’s decision about patient continuation in 
the study or patient withdrawal from the study if the patient has a positive response to the 
CSSRS Question 4, should be based on the Benefit /Risk balance for continuation or 
discontinuation of study treatment in view of the individual patient circumstances, condition, 
attained efficacy, causality, alternative risk management options, etc. Details of the case must 
be documented by the investigator (PI or investigator physician, not site staff conducting the 
CSSRS) and provided to UCB via the SAE reporting process.

11.7.6
Psychiatric and cognitive assessments
The overall psychiatric condition of the subjects will be assessed at screening using the BPRS 
and the MINI questionnaire. The BPRS is a questionnaire consisting of 16 questions which 
captures the psychiatric condition of the subject. 
The MINI is a widely used psychiatric structured diagnostic interview instrument. The MINI 
is divided into modules identified by letters corresponding to diagnostic categories. Rating is 
done to the right of each question by circling either Yes or No.
The MMSE is a sensitive, valid, and reliable 30-point questionnaire that is used extensively 
in clinical and research settings to measure cognitive impairment.
Further details about all questionnaires used in this study will be covered in the Study 
Manual.
11.7.7
Withdrawal monitoring
Any symptoms of withdrawal reactions will be monitored using the CIWA-B questionnaire. 
The CIWA-B questionnaire contains 22 questions which are selected to distinguish 
withdrawal symptoms from other symptoms. Further details about this questionnaire will be 
covered in the Study Manual.
12
STUDY MANAGEMENT AND ADMINISTRATION 
12.1
Adherence to protocol
The Investigator should not deviate from the protocol. In medical emergencies, the 
Investigator may use his/her medical judgment and may remove a study participant from 
immediate hazard before notifying UCB (or its representative) and the IEC in writing 
regarding the type of emergency and the course of action taken.
12.2
Monitoring
PRA will monitor the study to meet PRA’s monitoring Standard Operating Procedures 
(SOPs), ICH-GCP guideline, and applicable regulatory requirements, and to ensure that study 
initiation, conduct, and closure are adequate. Monitoring of the study may be delegated by 
UCB to a CRO or a contract monitor.
The Investigator and his/her staff are expected to cooperate with PRA and to be available 
during the monitoring visits to answer questions sufficiently and to provide any missing 
information. The Investigators/institutions will permit direct access to source data/documents 
for study-related monitoring, audits, IEC review, and regulatory inspection(s).
The Investigator will allow PRA to periodically review all eCRFs and corresponding source 
documents (eg, hospital and laboratory records for each study participant). Monitoring visits 
will provide the CRO with the opportunity to evaluate the progress of the study, verify the 
accuracy and completeness of eCRFs, ensure that all protocol requirements, applicable 
authorities regulations, and Investigator’s obligations are being fulfilled, and resolve any 
inconsistencies in the study records.
12.2.1
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).

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, or 
quality of life questionnaires, for example. Source documents should be kept in a secure, 
limited access area.
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, such as echocardiogram results, must be saved and stored as 
instructed by UCB (or designee).
12.2.2
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 eCRF should be 
supported by source documents, unless otherwise specified in Section 12.2.1.
12.3
Data handling
12.3.1
Case Report form completion
This study is performed using remote data capture. The Investigator is responsible for prompt 
reporting of accurate, complete, and legible data in the eCRFs and in all required reports.
Any change or correction to the eCRF 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 eCRF.
Detailed instructions will be provided in the eCRF Completion Guidelines.
12.3.2
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 eCRF 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.
12.3.3
Database lock
The database lock and unblinding may occur in a tiered approach. 
Details regarding the tiered database lock will be described in the Data Management Plan. 
Plans for analysis of data and production of tables, figures and listings will be described in 
the Statistical Analysis Plan (SAP).

12.3.4
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.
12.4
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 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.
12.5
Archiving and data retention
The Investigator will maintain adequate records for the study, including eCRFs, 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.
12.6
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 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).
12.7
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.
13
STATISTICS
A description of statistical methods follows and will be described in more detail in the SAP.
13.1
Definition of analysis sets
Analysis sets will be defined as follows:
∀
The Enrolled Set (ES) will consist of all subjects who signed the ICF.
∀
The Randomized Set (RS) will consist of all enrolled subjects who were randomized.
∀
The Full Analysis Set (FAS) will consist of all randomized subjects who received at 
least 1 dose of IMP and have at least 1 post-Baseline seizure diary.
∀
The Per-Protocol Set (PPS) will consist of all subjects in the FAS Population who do 
not have a major protocol deviation impacting the primary efficacy variable.
∀
The Safety Set (SS) will consist of all randomized subjects who receive at least 1 dose 
of IMP.
All primary and secondary efficacy analyses will be carried out using the FAS.
Selected supportive efficacy analyses will be carried out using the PPS.
Safety analyses will be carried out using the SS.

13.2
General statistical considerations
Summary statistics will be provided for all efficacy, safety, and Baseline/demographic 
variables. Summary statistics will consist of frequency tables for categorical variables. For 
continuous variables, descriptive statistics (number of available observations, mean, median, 
standard deviation [SD], minimum, maximum, 25th and 75th percentiles) will be tabulated. 
Unless otherwise mentioned, statistical hypothesis tests will be one-sided at the 5% 
significance level.
13.3
Planned efficacy analyses
The efficacy variables will be analyzed as described below using the FAS.
Total seizure frequency per week (7 days) will be derived from the seizure count information 
recorded on the diary card and is defined as the number of seizures standardized to a 7-day 
period. It is computed as the number of seizures recorded (by category: total, type I, type IA1, 
IB, and IC) over the period, divided by the total number of days in that period, multiplied 
by 7.
13.3.1
Analysis of the primary efficacy variable
The primary outcome measure is the 75%RR. In the active group, this is defined as the 
proportion of subjects with a 75% or greater reduction in focal seizure frequency during the 
last 2 weeks of the Inpatient Period compared to the 2-week Prospective Outpatient Baseline
Period. In the placebo group, the 75%RR is defined as the proportion of subjects with a 75% 
or greater reduction in focal seizure frequency during the first 2 weeks of the Inpatient Period 
(the 2 weeks on placebo) compared to the Prospective Outpatient Baseline Period. The 
75%RR will be analyzed using a logistic regression with effects for treatment, for LEV use 
stratification factor, and log-transformed Baseline seizure frequency as a continuous 
covariate. Odds-ratio of UCB0942 versus placebo groups and its 95% confidence intervals
(CI) will be estimated. The primary analysis will be performed on the FAS but also on the 
PPS.
13.3.2
Secondary efficacy analyses
Median percent reduction in seizures:
The percent reduction in total and partial seizure frequency from Baseline to the 
corresponding Treatment Period will be compared between UCB0942 arm and placebo using 
a Wilcoxon-Mann-Whitney test. The Hodges-Lehmann non-parametric estimator will be used 
to estimate the median percent reduction in seizures between groups and its corresponding 
95% CI will be provided. For secondary efficacy variables using responder rate (75%RR and 
50%RR), the analysis will be conducted similarly to the primary efficacy analysis 
(Section 13.3.1). Different treatment periods will be considered (inpatient as defined in 
Section 13.3.1, outpatient, and overall).
Seizure freedom:
To be considered seizure free, a subject must not report seizures of any type and must 
complete the corresponding treatment period. The seizure freedom rate will be analyzed 
using a logistic regression with effects for treatment and log-transformed Baseline seizure 
frequency as a continuous covariate. Odds-ratio of UCB0942 versus placebo groups and its 
95% CIs will be estimated. The seizure freedom will be evaluated at the following different 
treatment times: Inpatient Period as defined in Section 13.3.1, last 4 weeks of Outpatient 
Maintenance Period.

Percentage of seizure-free days:
A descriptive analysis will be performed on the percentage of seizure-free days by treatment 
group and study periods.
13.3.3
Exploratory efficacy analyses
Seizure severity:
Changes in the SSQ and average seizure severity as calculated by the percentage of seizures 
that are type IC from Baseline to the end of the Inpatient Period and the end of the Outpatient 
Maintenance Period will be analyzed.
The QOLIE-31-P (change from Baseline) will be analyzed by descriptive statistics and any 
relevant graphical displays. Relationship between QOLIE-31-P parameters and efficacy 
parameters (seizure reduction, 75%RR) will be evaluated.
Seizure frequency (continuous variable):
An analysis of covariance (ANCOVA) will be performed on the log-transformed weekly 
seizure frequency data. Specifically, ln(1+weekly seizure frequency during the Treatment 
Period) will be modeled with treatment group as factor and ln(1+weekly seizure frequency at 
Baseline) as covariate. Contrasts will be estimated to compare UCB0942 to observed placebo 
results.
All seizure frequency (Type I+II+III) and subtypes of partial seizures (Type IA, IB, IC) per 
week over the Treatment Period will be analyzed in a manner similar to the seizure 
frequency. Transformation of efficacy data could be envisaged given the data distribution. 
Different treatment periods will be considered (inpatient as defined in Section 13.3.1, 
outpatient, and overall).
Box-plots will be also displayed for the change in seizure frequency (absolute and 
percentage).
Exploratory analysis will be performed on the seizure count/SSQ data collected during the 
Tapering/Safety Follow-Up Period.
13.4
Planned safety and population PK analyses
13.4.1
Safety analyses
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 incidence of SAEs, AEs leading to premature discontinuation or dose 
tapering, and related AEs, and the incidence of AEs by maximum intensity, will also be 
summarized.
Laboratory values, ECG data (ventricular rate, PR, QTc [using Bazett’s and Fridericia’s 
formula], and QRS), vital signs, weight, and changes from Baseline in these measures will be 
summarized by period, visit, and treatment group. Possibly clinically significant treatment-
emergent abnormalities for laboratory values, vital signs, and weight will be listed and 
summarized by period and visit for each treatment group. 
Electrocardiogram abnormalities as well as physical and neurological abnormalities will also 
be listed by period and visit. Quantitative safety parameters will be summarized descriptively 
by time point and treatment group. Categorical safety summaries will provide the number and 
percentage of subjects within each summarized category. Doppler echocardiography results

at Baseline and during and after treatment, and changes from Baseline, will be listed and 
descriptively summarized.
All C-SSRS data obtained at Baseline and subsequent visits will be reported as a listing 
ordered by subject and visit. Psychiatric and cognitive assessments (MINI, BPRS, and 
MMSE) and CIWA-B data will also be covered using listings. Moreover, hypersensitivity 
reactions data will be summarized and listed.
13.4.2
PK analyses
13.4.2.1
Non-compartmental PK analysis
Plasma concentrations of UCB0942, 
 will be 
determined from blood samples obtained in the study, during the Titration and Maintenance 
Periods in order to investigate the PK of UCB0942 and its major metabolites.
The following PK parameters will be calculated:
! AUCτ:
area under the plasma concentration-time curve over a dosing interval, as 
determined using the linear trapezoidal rule.
! Cmax:
maximum observed plasma concentration.
! tmax:
time of Cmax.
! t½:
apparent terminal elimination half-life, reported in hours, as determined via 
simple linear regression (slope = -λz) of natural log(ln) concentration vs time 
for data points in the terminal phase of the concentration-time curve. t½ is 
calculated as ln(2)/λz.
! Ctrough:
measured concentration at the end of the dosing interval at steady state.
The PK variables will be computed by non-compartmental analysis (NCA) with Phoenix 
WinNonlin (version 6.2 or higher) using the actual sampling times. The linear trapezoidal 
method will be used to calculate AUC parameters.
PK parameters of UCB0942 and its metabolites will be listed and summarized using the 
following descriptive statistics: number of observations, geometric mean, lower and upper 
95% CI, geometric coefficient of variation (CV), arithmetic mean, SD, median, and minimum 
and maximum values. Graphical outputs over time will be produced on the trough plasma 
drug concentrations.
13.4.2.2
Population PK analysis
If appropriate, a population PK analysis will be conducted to characterize the PK of 
UCB0942, including inter-individual variability, and to assess the potential effect of 
concomitant AEDs on the PK of UCB0942. The population PK analysis will be based on 
plasma concentrations obtained during the Maintenance Week of the Inpatient Period, as well 
as samples collected during the Outpatient Maintenance Period. A separate data analysis plan 
(DAP) will describe the analysis, which will be reported in a separate report.
13.4.2.3
Population PK-PD analysis
Exploratory population PK-PD analysis may be performed if needed to characterize the 
relationship between exposure to UCB0942 and the clinical and/or safety clinical outcome. A 
separate DAP will describe the analysis, which will be reported in a separate report.

13.5
Handling of protocol deviations
After all lockable data have been verified/entered into a database and prior to the first 
database lock, a data evaluation meeting will take place. The purpose of the data evaluation 
will be to examine all protocol deviations, define the PPS, and to verify the quality of the 
data. The data evaluation will also help in guiding decisions on how to manage data issues on 
a case-by-case basis (eg, withdrawals, dropouts, and protocol deviations).
Accepted deviations from theoretical time points will be described in the appropriate 
documents and included in the Study Master File. After the data review, resolution of all 
issues, and documentation of all decisions, the database will be locked.
13.6
Handling of dropouts or missing data
The methods for handling dropouts will be described in the SAP.
13.7
Planned interim analyses and data monitoring
An interim analysis will be performed if needed for purposes of planning and designing of 
future studies. If performed, this analysis will be conducted when at least 75% of patients 
have been randomized and completed through the Inpatient Period (completed through 
Visit 5).
All subjects who have completed through Visit 5 at the time of the data snapshot will be 
included in the interim analysis.
All statistical analyses will be described in detail in the interim SAP.
For the interim analysis, the primary efficacy variable (75%RR) will be analyzed using the 
methods described for the primary efficacy analysis. In addition, seizure-free rate, 50%RR, 
and percent reduction in focal seizure frequency will be analyzed as described for the 
secondary/exploratory analyses.
The 75%RR, Seizure-free rate, and 50%RR variables may also be analyzed using Bayesian 
logistic regression. If Bayesian analysis is performed, the percent reduction in focal seizure 
frequency from the Baseline will be estimated using Bayesian analysis of variance (ANOVA) 
and/or ANCOVA. For these analyses, posterior medians, 95% credible intervals for the 
treatment effect, and additional posterior probabilities will be presented. Non informative and 
informative priors will be considered, and sensitivity to different prior settings will be 
assessed. Other efficacy variables may also be analyzed in the Bayesian framework.
The following safety data will also be presented: 
!
Treatment emergent AEs
!
AEs leading to drop-out or withdrawal
!
SAEs
!
Laboratory assessments out of normal range
!
BPRS
The study will not be terminated early for either efficacy or futility based on the results of 
this interim analysis and therefore, an alpha penalty of 0.001 to be assessed on the primary 
efficacy analysis is considered appropriate.

The study is not expected to be stopped due to safety reasons during this interim analysis, 
since there are ongoing quarterly Safety Review Group meetings already planned for this 
purpose. Therefore, no criteria for evaluation of early stopping due to safety are included.  
An unblinded team will be established at both the Sponsor and CRO and will include the 
following roles (all unblinded): Data Manager, Statistician, Statistical Programmer, and 
Project Lead. All staff involved in the conduct of the study, including staff at UCB, the CRO, 
participating vendors, and the participating sites will remain blinded to individual treatment 
identity and will not be informed of the results of the interim analysis until final unblinding. 
13.8
Determination of sample size
This is an exploratory pilot study to obtain a first evaluation of the efficacy (estimate and 
variability) of UCB0942 in this specific refractory population. The planned sample size was 
evaluated based on placebo results obtained in similar refractory epileptic populations from
BRV and lacosamide Phase 3 studies in add-on partial epilepsy, and the desired effect was 
based on a doubling of the effect of lacosamide and BRV in subjects in the current target 
population.
For the primary efficacy variable, the 75%RR in the placebo group from these historical 
studies was estimated to be less than 5%. The response on UCB0942 was expected to be 
36.5% in order to provide clear differentiation from lacosamide and BRV in this patient 
population. 
Based on a 2-group Fisher's exact one-sided test with a ratio active:placebo of 1:1, the 
required number of subjects is 23 in each arm to detect a significant difference between the 
2 groups with a power of 80% and a false positive rate of 5%.
14
ETHICS AND REGULATORY REQUIREMENTS
14.1
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 ICF 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 ICF. As part of the consent process, each subject must 
consent to direct access to his/her medical records for study-related monitoring, auditing, IEC 
review, and regulatory inspection.
If the ICF 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 ICF
by the IEC and use of the amended form.
The subject may withdraw his/her consent to participate in the study at any time. A subject is 
considered as enrolled in the study when he/she has signed the Informed Consent form. An
eCRF must not be started, nor may any study specific procedure be performed for a given 
subject, without having obtained his/her written consent to participate in the study.

14.2
Subject identification cards
Upon signing the Informed Consent 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.
14.3
Subject compensation
In addition to reimbursement of incurred expenses (eg, travel), subjects will be financially 
compensated for the burden and inconvenience of spending time at the inpatient unit as this is 
an unusual requirement for participants in clinical studies. The amount of compensation will 
be country-specific and approved by the local ethics committee.
14.4
Independent Ethics Committees
The study will be conducted under the auspices of an 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 will ensure that an appropriately constituted 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 will forward copies of the protocol, 
Informed Consent 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 IEC for its review and approval.
Before initiating a study, the Investigator will have written and dated full approval from the 
responsible IEC for the protocol.
The Investigator will also promptly report to the 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 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 
IEC as allowed.
As part of the IEC requirements for continuing review of approved studies, the Investigator 
will be responsible for submitting periodic progress reports to the IEC (based on 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 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 IEC will also be informed by the Investigator or the Sponsor, as specified by 
the applicable regulatory requirements in each concerned country. Where applicable, 
Investigators are to provide the Sponsor (or its representative) with evidence of such IEC 
notification.

Subject privacy
UCB staff (or designee) will affirm and uphold the subject’s confidentiality. Throughout this 
study, all data forwarded to UCB (or designee) will be identified only by the subject number 
assigned at Screening.
The Investigator agrees that representatives of UCB, its designee, representatives of the 
relevant IEC, or representatives of regulatory authorities will be allowed to review that 
portion of the subject’s primary medical records that directly concerns this study (including, 
but not limited to, laboratory test result reports, ECG reports, admission/discharge summaries 
for hospital admissions occurring during a subject’s study participation, and autopsy reports 
for deaths occurring during the study).
14.6
Protocol amendments
Protocol changes may affect the legal and ethical status of the study and may also affect the 
statistical evaluations of sample size and the likelihood of the study fulfilling its primary 
objective.
Significant changes to the protocol will only be made as an amendment to the protocol and 
must be approved by UCB, the IECs, and the regulatory authorities (if required), prior to 
being implemented.

APPENDICES
17.1
Protocol Amendment 1.0
Rationale for the amendment
The addition of an echocardiogram during dosing was made as a result of comments from the 
Federal Institute for Drugs and Medical Devices (Bundesinstitut für Arzneimittel und 
Medizinprodukte). They have requested the addition of an echocardiogram during dosing. 
This echocardiogram has been added at Day OP22. In addition, the following changes were 
made:
-
It has been clarified that either urine or serum pregnancy tests can be used for all 
visits. 
-
It has been pointed out that the decision to continue in the OLE will occur at
Day OP43. 
-
Clarification on the procedure for dose reduction in cases of poor tolerability of 
UCB0942 400mg bid (ie, reduction to UCB0942 200mg bid and in some cases to 
UCB0942 100mg bid).
-
The withdrawal criteria for elevated transaminases have been reworded as the 
previous description was not clear.

Section 6.3 Withdrawal criteria, criterion #1
Subject develops a clinically relevant medical condition (or laboratory abnormality) that, in 
the opinion of the Investigator, compromises the subject’s ability to participate or safety. In 
the case of transaminase (AST, ALT, or both) levels at least 3 times the upper limit of normal 
(ULN) to less than 5 times the ULN, in the presence of normal total bilirubin, the laboratory 
tests will be repeated within a few days. If the repeat testing confirms the abnormality (ie, 
transaminases are at least 3 times the ULN to less than 5 times the ULN with normal 
bilirubin), then weekly monitoring of liver function tests should continue until resolved (ie, 
less than 3 times the ULN or stable condition). The Investigator is to decide whether or not to 
stop the investigational medicinal product (IMP). To monitor for hypersensitivity reactions, 
percent eosinophils >10% or absolute eosinophil count ≥0.5G/L or absolute neutrophil count 
<1.5G/L or absolute platelet count ≤100G/L, if in combination with fever, rash, 
lymphadenopathy, or other symptoms/signs suggestive of internal organ involvement 
(including but not limited to hepatitis, nephritis, pneumonitis, carditis, colitis, encephalitis, 
pancreatitis, myositis, or arthritis) will lead to stopping the IMP.

17.2
Protocol Amendment 2.0
Rationale for the amendment
The protocol describes the use of video monitoring during the Inpatient Period. The video 
monitoring is an exploratory endpoint, and the data will be used to assess the difference 
between seizure diaries (the primary endpoint) and seizures detected with video. The 
intention of the protocol language was to let sites perform video monitoring according to their 
usual clinical practice; however, the language in the first version was not sufficiently clear to 
convey this flexibility. The purpose of this amendment is to make the video monitoring 
language in the protocol more flexible so that sites/Investigators can perform this according 
to their usual practice. This new language will also allow video-EEG monitoring as some 
sites do not perform video-only monitoring. 
A second change was the wording of the drug misuse exclusion criterion. As is customary in 
most UCB protocols, exclusion for drug misuse is only applicable if the Investigator deems 
that study participation is either a risk to the subject or that the drug misuse could confound 
the outcomes measured in the study. The wording of this exclusion criterion was changed to 
match that of other UCB studies.
In addition, the possibility of rescreening screening failures was added.

Video monitoring
During all inpatient periods, there will be continuous video monitoring in subjects’ rooms 
(and at some sites in other areas) to allow exploratory analysis of seizure type, severity, and 
duration, and of the duration of the postictal period.
Has been changed to:
At the discretion of the Investigator, sites may or may not perform video or video-EEG
monitoring during part of the Inpatient Period or during the whole Inpatient Period,

Protocol Amendment 3.0
Rationale for the Amendment
The primary reason for Amendment 3 is to add and describe an optional interim analysis for 
purposes of planning and designing of future studies. 
Other reasons for the amendment include the following: 
!
To add an exploratory objective, variable and associated assessment (diary 
addendum). Note that this was already part of the study, but not clearly described in 
the protocol.
!
To clarify procedures for dosing when there is intolerance to study medication during 
the Inpatient Period
!
To allow and specify flexibility in dosing during the Outpatient Maintenance Period
!
To further specify which Subjects require an echocardiogram at 6 months after the 
last dose of study medication
!
To expand the range of BMIs allowed for inclusion in the study
!
To revise procedures for assessment of suicidality using the C-SSRS (specifically, the 
C-SSRS withdrawal criterion) in line with revision to sop-ai-015774, Version 2.0,
which became effective on 01 Apr 2016. 
!

Dosing in the Outpatient Maintenance Period and Tapering Period
During the Outpatient Maintenance Period, Subjects will continue to administer UCB0942 at 
the final Inpatient Period dose. Multiple adjustments (tapering or increase) of the dose are 
allowed during the Outpatient Maintenance Period (minimum 100mg bid and maximum 
400mg bid); however, any change of dose in the Outpatient Maintenance Period should first 
be discussed with the Sponsor Study Physician. 
At the end of the Outpatient Maintenance Period, or at the time a subject is withdrawn from 
the study, UCB0942 will be tapered following the schedule in Table 5-3. If the subject is not 
taking a dose of UCB0942 other than 400mg bid, then the Investigator should contact the 
Sponsor Study Physician to discuss the appropriate tapering schedule.

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 Case Report form (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.

Section 6.3 Withdrawal criteria, Withdrawal Criterion #1
Subject develops a clinically relevant medical condition (or laboratory abnormality) that, in 
the opinion of the Investigator, compromises the subject’s ability to participate or safety. In 
the case of transaminase (AST, ALT, or both) levels at least 3 times the upper limit of normal 
(ULN) in the presence of normal total bilirubin, the laboratory tests will be repeated within a 
few days. If the repeat testing confirms the abnormality, then weekly monitoring of liver 
function tests should continue until resolved (ie, less than 3 times the ULN or stable 
condition). The Investigator is to decide whether or not to stop the investigational medicinal 
product (IMP). To monitor for hypersensitivity reactions, percent eosinophils >10% or 
absolute eosinophil count ≥0.5G/L or absolute neutrophil count <1.5G/L or absolute platelet 
count ≤100G/L, if in combination with fever, rash, lymphadenopathy, or other 
symptoms/signs suggestive of internal organ involvement (including but not limited to 
hepatitis, nephritis, pneumonitis, carditis, colitis, encephalitis, pancreatitis, myositis, or 
arthritis) will lead to stopping the IMP.

Section 6.3 Withdrawal criteria
Added Section 6.3.1 Potential drug-induced liver injury IMP 
discontinuation criteria: 
Subjects with potential drug-induced liver injury (PDILI) must be assessed to determine if 
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%).
If a nondrug-related cause for the symptoms can be confirmed, these subjects may resume 
IMP administration after discussion with the responsible UCB physician, but only when the 
requirements for rechallenge with IMP as provided in Section 11.6.1.2.1 are followed.
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).
Evaluation of PDILI must be initiated as described in Section 11.6.1. If subjects are unable to 
comply with the applicable monitoring schedule, IMP must be discontinued immediately.
Investigators should attempt to obtain information on subjects in the case of IMP 
discontinuation to complete the final evaluation. Subjects with PDILI should not be 
withdrawn from the study until investigation and monitoring are complete. All results of 
these evaluations and observations, as well as the reason(s) for IMP discontinuation and 
subject withdrawal (if applicable), must be recorded in the source documents. The CRF must 
document the primary reason for IMP discontinuation.

be tapered to UCB0942 200mg bid. This is only permitted if the subject has great difficulty 
tolerating the IMP and the Investigator does not think that tolerability will improve. When it 
is decided to reduce the dose, the blind will have to be broken, following the procedure 
described in Section 7.9.1.2.
Has been changed to: 
When the Investigator and Sponsor Study Physician agree that a subject cannot titrate to the

Section 11.6 Laboratory assessments
Added Section 11.6.1 Evaluation of PDILI:
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 11.3), and, if applicable, also 
reported as an SAE (see Section 11.1.1).
Evaluation of PDILI consists of the diagnostic testing and continued monitoring included in 
Table 11-3 (specific tests dependent on laboratory results and corresponding symptoms) and 
consultation with a local hepatologist (if applicable; discussed in Section 11.6.1.1). 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 11.6.1.4). 
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.
When IMP is stopped due to PDILI (as described in Section 6.3.1), IMP must be permanently 
discontinued unless a subsequent alternative diagnosis fully explains the hepatic findings. If a 
subsequent alternative diagnosis fully explains the hepatic findings, and the requirements 
provided in Section 11.6.1.2.1 are met, rechallenge with IMP may be appropriate. 
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.

11.6.1.1
Consultation with the 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 11.6.1.3) and SAE report (if 
applicable).
11.6.1.2
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 11‒3 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 for medically necessary concomitant medication and consider changing any 
medically required concomitant medication known to be hepatotoxic to a suitable alternative.
11.6.1.2.1
IMP restart/rechallenge (if applicable)
Rechallenge with a substance potentially causing drug-induced liver injury is dangerous, may 
be fatal, and must not occur.
Subjects who are immediately discontinued from IMP due to having met certain criteria for 
PDILI (as described in Section 6.3.1 and Table 11‒3), but for whom an alternative diagnosis 
is confirmed, can rarely restart IMP. Rechallenge with IMP can occur only if ALL of the 
following requirements are met:
!
The results of additional testing and monitoring described in Section 11.6.1.3 and 
Section 11.6.1.4 confirm a nondrug-related cause for the abnormal hepatic laboratory 
parameters and any associated symptoms (ie, a subsequent alternative diagnosis fully 
explains the hepatic findings). 
!
No alternative treatment options are available to the subject.
!
The subject has shown clear therapeutic benefit from the IMP.
!
Subject’s ALT or AST elevations do not exceed ≥3xULN.
!
Subject’s total bilirubin is <1.5xULN.
!
Subject has no signs or symptoms of hypersensitivity. 
!
The rechallenge is approved by the UCB responsible physician and a hepatologist. The 
hepatologist must be external to UCB. It is recommended that the hepatologist be a local 
hepatology expert or the hepatologist treating the subject.
!
Subject agrees to the investigator-recommended monitoring plan.
11.6.1.3
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

Section 13.7 Planned interim analyses and data monitoring
This Section has been added: 
An interim analysis will be performed if needed for purposes of planning and designing of 
future studies. If performed, this analysis will be conducted when at least 75% of patients 
have been randomized and completed through the Inpatient Period (completed through 
Visit 5).
All subjects who have completed through Visit 5 at the time of the data snapshot will be 
included in the interim analysis.
All statistical analyses will be described in detail in the interim SAP.
For the interim analysis, the primary efficacy variable (75%RR) will be analyzed using the 
methods described for the primary efficacy analysis. In addition, seizure-free rate, 50%RR, 
and percent reduction in focal seizure frequency will be analyzed as described for the 
secondary/exploratory analyses.
The 75%RR, Seizure-free rate, and 50%RR variables may also be analyzed using Bayesian 
logistic regression. If Bayesian analysis is peformed, the percent reduction in focal seizure 
frequency from the Baseline will be estimated using Bayesian analysis of variance (ANOVA) 
and/or ANCOVA. For these analyses, posterior medians, 95% credible intervals for the 
treatment effect, and additional posterior probabilities will be presented. Non informative and 
informative priors will be considered, and sensitivity to different prior settings will be 
assessed. Other efficacy variables may also be analyzed in the Bayesian framework.
The following safety data will also be presented: 
!
Treatment emergent AEs
!
AEs leading to drop-out or withdrawal
!
SAEs
!
Laboratory assessments out of normal range
!
BPRS
The study will not be terminated early for either efficacy or futility based on the results of 
this interim analysis and therefore, an alpha penalty of 0.001 to be assessed on the primary 
efficacy analysis is considered appropriate.  
The study is not expected to be stopped due to safety reasons during this interim analysis, 
since there are ongoing quarterly Safety Review Group meetings already planned for this 
purpose. Therefore, no criteria for evaluation of early stopping due to safety are included.  
An unblinded team will be established at both the Sponsor and CRO and will include the 
following roles (all unblinded): Data Manager, Statistician, Statistical Programmer, and 
Project Lead. All staff involved in the conduct of the study, including staff at UCB, the CRO, 
participating vendors, and the participating sites will remain blinded to individual treatment 
identity and will not be informed of the results of the interim analysis until final unblinding.

Summary (revised for consistency with Section 5, Study Design)
Titration to UCB0942 400mg bid will occur over the course of 1 week in the clinical unit. 
For subjects in the active arm, doses will be titrated to UCB0942 400mg bid during the first 
inpatient week. For subjects who initially received placebo, doses will be titrated to 
UCB0942 400mg bid during the last week of the Inpatient Period. For subjects in the active 
arm who do not tolerate UCB0942 400mg bid, during the third week of the Inpatient Period, 
the dose can be tapered to UCB0942 200mg bid before starting the Outpatient Maintenance 
Period. Similarly, for subjects in the placebo group the dose can be tapered to UCB0942 
200mg bid during the Outpatient Maintenance Period. Dose tapering to UCB0942 100mg bid 
may be permitted after discussion with the Sponsor’s Study Physician. All subjects will stay 
in the clinical unit for a total of 3 weeks and will then be discharged for an 8-week 
Outpatient Maintenance Period.

Section 9.2 Seizure severity questionnaire
The SSQ (Cramer et al, 2002) is a review of various aspects of seizures. The person who has 
seizures may ask people who have observed the seizures (family, friends) to help answer 
some of the questions asking about events, but not about feelings. There are 11 questions in 3 
sections asking about events before, during, and after typical seizures.
The subject should describe their most common type of seizure when answering the 
questions. If subjects are unsure about how to answer a question, they should give the best 
answer they can and write a comment or explanation on the side of the page. 
The SSQ will be completed according to the tabular schedule of study procedures, Table 5-4. 
For this study the recall period will be set to 1 week rather than the original 4 weeks. At the 
very beginning of the visit, the SSQ will be provided to all subjects. The subject will be asked 
to complete the questionnaire on his/her own. Once completed, the subject will return the 
completed questionnaire to the Investigator or designee, who will verify that all questions 
have been answered. Further details about the SSQ will be covered in the Study Manual.

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.
Has been changed to (change bolded): 
In order to ensure complete safety data collection, all AEs occurring during the study 
(ie, after the signing of the Informed Consent form), including any pretreatment and 
posttreatment periods required by the protocol, ie, through the end of the Taper/Safety 
Follow-up Period, must be reported in the eCRF 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.
Change #7
Section 11.1.4, Follow up of of adverse events, paragraph 2
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.

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.
Adverse events should not be recorded in the eCRF after the end of the Taper/Safety 
Follow-up Period.

Section 11.1.9, Safety Review Group, paragraph 3
The SRG will remain blinded during the study unless emergent safety information requires 
unblinding of individual drug allocation for optimal assessment and response to AEs of 
concern.
Has been changed to: 
The SRG will remain blinded through the first database lock (see Section 12.3.3) unless 
emergent safety information requires unblinding of individual drug allocation for optimal

Section 11.6.1, Evaluation of PDILI
Several incorrect table and section references have been corrected. 
Change #10
Section 12.3.3, Database lock – section has been added: 
The database lock and unblinding may occur in a tiered approach. 
Details regarding the tiered database lock will be described in the Data Management Plan. 
Plans for analysis of data and production of tables, figures and listings will be described in 
the Statistical Analysis Plan (SAP).
Change #11
Section 13.5, Handling of protocol deviations, paragraph 1
After all data have been verified/entered into a database and prior to database lock, a data 
evaluation meeting will take place. The purpose of the data evaluation will be to examine all 
protocol deviations, define the PPS, and to verify the quality of the data. The data evaluation 
will also help in guiding decisions on how to manage data issues on a case-by-case basis (eg, 
withdrawals, dropouts, and protocol deviations).

INTRODUCTION
The purpose of this statistical analysis plan (SAP) is to provide all information that is necessary 
to perform the required statistical analysis of data collected in EP0069. It also defines the 
summary tables, listings, and figures (TFLs) to be included in the final Clinical Study Report 
(CSR) according to the protocol.
This SAP is based upon, and assumes familiarity, with the following study documents:
Protocol Amendment 4: 05 October 2016
Unless specified below, the study will be analyzed as described in the most recent version of the 
protocol (EudraCT-Number: 2014-003330-12).
If a future protocol amendment necessitates a substantial change to the statistical analysis of the 
study data, this SAP will be amended accordingly. If, after database lock, additional analyses are 
required to supplement the planned analyses described in this SAP, those unplanned analyses 
will not be described in the amended SAP but they will be described in a separate analysis plan.
However, if analysis definitions have to be modified or updated, a SAP amendment will be 
required. The content of this SAP is compatible with the International Conference on 
Harmonization (ICH)/ Food and Drug Administration (FDA) E9 Guidance documents (ICH E9, 
1998). 
UCB is the Sponsor and PRA is the Contract Research Organization (CRO) for this study.

PROTOCOL SUMMARY
2.1
Study objectives
2.1.1
Primary objective
The primary objective is to evaluate the efficacy of UCB0942 administered concomitantly with 
each subject’s current, stable antiepileptic drug (AED) regimen in subjects who have 4 or more 
focal seizures with or without secondary generalization per week and who have failed to achieve 
seizure control with ≥4 AED regimens of adequate dose and duration.
2.1.2
Secondary objectives
The secondary objectives are to:
!
Evaluate the safety and tolerability of UCB0942.
!
Evaluate the pharmacokinetics (PK) of UCB0942 and its metabolites.
2.1.3
Exploratory objectives
The exploratory objectives are to:
!
Identify genetic polymorphisms, gene expression patterns, plasma proteins, plasma lipids 
or other plasma substances that predict or are associated with disease etiology, drug
response, or tolerability.
!
Use video recordings to explore the effect of UCB0942 on seizure type, seizure severity, 
seizure duration and duration of the postictal period. 
!
Evaluate the efficacy of UCB0942 using exploratory efficacy variables.

Study variables
2.2.1
Efficacy variables
The periods for which the efficacy variables are calculated are described in Section 3.2.1.2.
2.2.1.1
Primary efficacy variable
Seizure frequency will be determined using subject diary cards. The subject will be instructed as 
to how to complete the diary and the procedure for completing the diary will be identical during 
the Inpatient and Outpatient Maintenance Periods.
The primary outcome measure is the 75% responder rate (75%RR). In the active group this is 
defined as the proportion of subjects with a 75% or greater reduction in the focal seizure (IA1, 
IB, IC) frequency during the last 2 weeks of the Inpatient Period compared to the 2-week 
Prospective Outpatient Baseline. In the placebo group the 75%RR is defined as the proportion of 
subjects with a 75% or greater reduction in the focal seizure frequency during the first 2 weeks 
of the Inpatient Period (the 2 weeks on placebo) compared to the Prospective Outpatient Baseline
Period.
2.2.1.2
Secondary efficacy variables
The 2-week Inpatient Period to be considered is the last 2 weeks of the Inpatient Period for the 
active group, and the first 2 weeks of the Inpatient Period for the placebo group (see 
Section 3.2.1.2).
The secondary efficacy variables are:
!
Median percent reduction in focal seizure frequency from the Baseline Period to the 2-week 
Inpatient Period, the Outpatient Maintenance Period and On-UCB0942 Overall.
!
Seizure-free rate during the 2-week Inpatient Period, the last 4 weeks of the Outpatient 
Maintenance Period, and the On-UCB0942 Overall Period (Section 3.10.2 ).
!
The 75%RR during the last 4 weeks of the Outpatient Maintenance Period, and 
On-UCB0942 Overall.
!
Percentage of seizure-free days during the 2-week Inpatient Period and Outpatient
Maintenance Period (Section 3.10.2).
2.2.1.3
Exploratory  efficacy variables
For all the exploratory efficacy variables, the Inpatient Period to be considered for the active 
group is the last 2 weeks and for the placebo group is the first 2 weeks of the Inpatient Period.
Exploratory efficacy variables are as follows:
!
Median seizure frequency by focal seizure type (IA1, IB, IC) per study period: Baseline, 1st 
Inpatient Week, 2nd Inpatient Week, 3rd Inpatient Week, the 2-week Inpatient Period,
Outpatient Maintenance Period, and On-UCB0942 Overall.
!
The 50% responder rate (50%RR) during the 2-week Inpatient Period and during the 
Outpatient Maintenance Period.
!
Seizure Severity Questionnaire score (SSQ, Cramer et al, 2002) change from Baseline to the 
end of the Inpatient Period and the end of the Outpatient Maintenance Period.

2.2.2
Pharmacokinetic variables
Plasma concentrations of UCB0942, 
 will be used to 
derive PK-population parameters.
The following PK variables will be calculated:
!
AUCτ: area under the plasma concentration-time curve over a dosing interval.
!
Cmax:
maximum observed plasma drug concentration.
!
tmax:
time of occurrence of Cmax.
!
t½:
apparent terminal elimination half-life, reported in hours. 
!
Ctrough: measured concentration at the end of a dosing interval at study state. 
2.2.3
Other exploratory variables
Blood samples for DNA, mRNA, and lipidomics/proteomics/additional blood biomarkers will be 
collected during the study:
!
DNA: One tube for DNA isolation will be collected at the beginning of the Inpatient Period 
of the study. The DNA may be used to assess known variants associated with drug-resistant 
epilepsy or AED resistance and may be used for further genetic analyses relating to epilepsy 
and drug response.
!
mRNA: One tube will be collected on the day before the first dose of UCB0942/placebo, and 
1 tube will be collected on the last day of the Inpatient Maintenance Dose Week. The mRNA 
samples may be used to identify gene expression patterns that are associated with disease 
etiology, that predict (Baseline sample), or that are associated with (post-treatment sample) 
drug response.
!
Lipidomics/proteomics/additional blood biomarkers: One tube will be collected on the 
day before the first dose of UCB0942 or placebo, and 1 tube will be collected on the last day 
of the Inpatient Maintenance Dose Week. These samples may be used for additional blood 
biomarker analysis.
All subjects will be asked to provide specific consent for these samples. Refusal to provide 
consent for the collection of samples for DNA, mRNA, and lipidomics/proteomics will not 
disqualify the subject from participating in the study.
Single archive blood samples (for potential background AED assay) will be collected at the start 
of titration, the end of the Inpatient Period, and at the end of the Outpatient Maintenance Period 
(before last dose of investigational medicinal product [IMP]). These samples will be collected 
just before the morning dose of IMP and stored for up to 1 year after the study ends.
During the Inpatient Period, there will be video monitoring of subjects  in their rooms (and in 
other areas depending on the infrastructure of each site) to allow detection of nocturnal seizures

duration of the postictal period. The video data will not be used to corroborate or supplement the 
diary data and shall not influence the diary seizure capture by the subject.
2.2.4
Safety variables
The safety of participating subjects will be closely monitored. Psychiatric assessment will be 
performed by a staff member trained in the identification of psychiatric symptoms, and the 
assessments will be performed using the Brief Psychiatric Rating Scale (BPRS; Overall and 
Gorham, 1962), which assesses various psychiatric domains including: 
!
Changes in mood and symptoms of depression or mania.
!
Changes in thinking and perception, and other symptoms of psychosis.
!
Changes in behavior.
Other safety variables are:
!
Adverse events (AEs) reported by the subject and/or caregiver or observed by the 
Investigator or inpatient staff.
!
Serious AE (SAEs).
!
Subject withdrawals or premature UCB0942 tapering due to AEs.
!
Changes in clinical laboratory test parameters.
!
Changes in vital sign parameters – pulse rate (PR), systolic blood pressure (SBP), diastolic 
blood pressure (DBP), and respiratory rate.
!
Changes in 12-lead electrocardiogram (ECG) parameters.
!
Changes in key cardiac structures on 2-dimensional Doppler echocardiography from Baseline 
to after treatment (end of dosing and 6 months after last dose).
!
Changes in physical examination (including body weight) and neurological examination 
findings.
!
Changes in memory or cognition as assessed with the mini-mental state examination 
(MMSE; Folstein et al, 1975).
!
Changes indicative of a hypersensitivity reaction including an AE or laboratory value (as 
defined below) suggestive of internal organ involvement (including but not limited to 
hepatitis, nephritis, pneumonitis, carditis, colitis, encephalitis, pancreatitis, myositis, arthritis, 
or hematologic system involvement) combined with at least 1 of the following: fever, rash, 
lymphadenopathy, or eosinophilia.
∀
Treatment-emergent abnormal laboratory value criteria suggestive of internal organ 
involvement or eosinophilia:

Study design and conduct
EP0069 is a Phase 2A, double-blind, randomized, placebo-controlled, multicenter study that will 
test the potential efficacy, safety/tolerability, and PK profile of UCB0942 in adult subjects with 
highly drug-resistant focal epilepsy. 
At least 46 subjects will be randomized 1:1 to receive UCB0942 400mg bid or placebo as add-on 
to each subject’s concomitant AED regimen. Stratified randomization will be used to ensure 
balance in the 2 treatment arms on the levetiracetam (LEV)-use factor (3 strata):
1. LEV prior and current use (concomitant use of LEV at study entry).
2. LEV Prior Use Only=History of prior LEV use and must have discontinued 4 weeks prior to 
study entry.
3. LEV Naïve=No history of prior LEV use, and no use at study entry.
All subjects will stay in the clinical unit for a total of 3 weeks and will then be discharged for an 
8-week Outpatient Period. Titration to UCB0942 400mg bid will occur over the course of 1 week 
in the clinical unit. Subjects in the active arm will be titrated to UCB0942 400mg bid, during the 
first inpatient week. Subjects who initially received placebo will be titrated to UCB0942 400mg 
bid during the last week of the 3-week Inpatient Period. For subjects in the active arm who do 
not tolerate UCB0942 400mg bid, during the third week of the Inpatient Period the dose can be 
tapered to UCB0942 200mg bid before starting the 8-week Outpatient Period. Similarly, for 
subjects in the placebo group the dose can be tapered to a tolerable dose during the Outpatient 
Period. 
For a general presentation of the study design refer to Figure 2‒1.
The total duration of the study after Screening is 20 weeks for each subject, including the 
Prospective Outpatient Baseline Period (2 to 3 weeks), the Inpatient Period (3 weeks), the 
Outpatient Period (8 weeks of treatment and 2 weeks of taper), and a Safety Follow-Up (SFU)
Period (4 weeks). The total duration of exposure to UCB0942 during this study is 13 weeks.
Subjects who drop out prior to their Visit 6 may be replaced.

An echocardiogram is planed to be performed 6 months after the last dose. If not all 
echocardiographs are completed by the time of the initial database locks, the database will be 
unlocked so that the echocardiography data will be included and cleaned. These data will be 
reported in an addendum.
2.4
Determination of sample size
This is an exploratory pilot study to obtain a first evaluation of the efficacy (estimate and 
variability) of UCB0942 in this specific refractory population. The planned sample size was 
evaluated based on placebo results obtained in similar refractory epileptic populations from 
brivaracetam (BRV) and lacosamide Phase 3 studies in add-on focal epilepsy and the desired 
effect was based on a doubling of the effect of lacosamide and BRV in patients in the current 
target population.
For the primary efficacy variable, the 75%RR in the placebo group from these historical studies 
was estimated to be less than 5%. The response on UCB0942 was expected to be 36.5% in order 
to provide clear differentiation from lacosamide and BRV in this patient population. Based on a 
two-group Fisher's exact one-sided test with a ratio active:placebo of 1:1, the required number of 
subjects is 23 in each arm to detect a significant difference between the two groups with a power 
of 80% and a false positive rate of 5%.

All analysis will be performed using SAS® version 9.3, or higher (SAS Institute, Cary, NC, 
USA). The PK variables will be computed by non-compartmental analysis (NCA) with Phoenix 
WinNonlin® (version 6.2, or higher) using the actual sampling times. 
A glossary of common abbreviations will be provided and will contain abbreviations not 
footnoted in the tables, figures, and listings.
For continuous variables, summary statistics will include number of observations (n), mean, 
median, quartiles, standard deviation (SD), minimum, and maximum, and may also include 95% 
confidence intervals (CI). Categorical endpoints will be summarized using number of subjects, 
frequency, and percentages. Coefficient of variation (CV), geometric mean, and 95% CI will also 
be presented in the descriptive statistics for PK parameters. Missing data will not be imputed
apart from the exceptions as outlined in Section 4.2.
When reporting relative frequencies or other percentage values, the following rules apply:
!
For values where all subjects fulfill certain criteria, the percentage value will be displayed as 
100.
!
For values where the absolute frequency is 0, there will be no percentage presented at all.
!
All other percentage displays will use 1 decimal place. 
When reporting descriptive statistics, the following rules will apply in general:
!
n will be an integer.
!
Mean, SD, and median will use 1 decimal place more than the original data.
!
The CV will be reported as a percentage to 1 decimal place. 
!
Minimum and maximum will be reported using the same number of decimal places as the 
original value.
!
If no subjects have data at a given timepoint, for example, then only n=0 will be presented. 
However, if n<3, present the n, minimum and maximum only. If n=3, n, mean, median, 
minimum and maximum will be presented only. The other descriptive statistics will be left 
blank. 
Details of statistical summaries for safety are described in Section 9.
General statistical and reporting conventions are outlined in UCB Global Statistical Conventions; 
Version 1.0 dated 26 June 2013.
For PK calculations the User guide for Clinical Pharmacokinetics Modeling and Simulation; 
Version 8.0, dated 4 July 2012 of UCB will be considered as guideline.

General study level definitions
3.2.1
Analysis timepoints 
3.2.1.1
Relative day
The relative day of an event will be derived with the start date of first IMP administration as 
reference date, up to and including the last day of the IMP administration:
!
Active group: Date of the first/last UCB0942 administration  (including the tapering period, 
where applicable)
!
Placebo group: Date of the first Placebo administration /last Placebo administration (before 
the first UCB0942 administration).
Relative days for an event or measurement occurring before the reference date are calculated as 
follows:
Relative Day=(Event Date-Reference Date)
Relative days for an event or measurement occurring on or after the reference date to the last day 
of IMP administration are calculated as follows:
Relative Day=(Event Date-Reference Date)+1
For events or measurements occurring after the date of last dosing (as defined above), the 
relative day will be calculated with the date of last IMP administration as reference. Relative day 
in this case will be prefixed with ‘+’ in the data listings and will be calculated as follows:
Relative Day=+(Event Date-Reference Date)
Therefore, for the active group, every relative day post the tapering period will be presented with 
a prefix, and for the placebo group, every day since the first UCB0942 dose (2nd Inpatient Week) 
be presented with a prefix.
There is no relative Day 0. Relative day is not calculated for partial dates in cases where relative 
day is shown in a subject data listing. In such cases, relative day should be presented as ‘--’ in 
the subject data listings.
3.2.1.2
Study periods
The following periods, and their combinations will be considered in the definition of efficacy 
and safety variables:
!
Baseline Period: Prospective Outpatient Baseline Period consisting of 2 to 3 weeks of 
prospective post-screening subject diary seizure counts.
!
Inpatient Period: The Double-Blind Inpatient Treatment Period, with the following sub-
periods.
∀
1st Inpatient Week: Double-Blind Titration Week (active group on UCB0942 titration; 
placebo group on placebo)
∀
2nd Inpatient Week: Double-Blind Maintenance-Dose Week (active group on UCB0942 
maintenance; placebo group on placebo)

Important protocol deviations are deviations from the protocol which could potentially have a 
meaningful impact on the study conduct or on the primary efficacy outcome, secondary efficacy 
variables, PK data or key safety data for an individual subject. Important protocol deviations will 
be reviewed as part of the data cleaning process and all important deviations will be identified 
and documented to confirm exclusion from the analysis sets.
After all data have been verified/coded/entered into a database, all protocol deviations will be 
classified according to their impact on study objectives during the database pre-lock data 
evaluation meeting (DEM). The purpose of this meeting will be to check all protocol deviations, 
define the analysis sets, and check the quality of the data. The review will also help decide how 
to manage problems in the subjects’ data (e.g., missing values, withdrawals, dropouts, and 
protocol deviations). After the classification of all deviations, Statistical Programming will then 
incorporate the definition of the analysis populations into the analysis files for statistical 
evaluation. If necessary, appropriate actions will be implemented in the SAP before locking the 
database. After the pre-analysis review, resolution of all issues, and documentation of all 
decisions, the database will be locked.
3.5
Analysis sets
3.5.1
Enrolled Set
The Enrolled Set (ES) will consist of all subjects who have signed the informed consent form 
(ICF).
3.5.2
Randomized Set
The Randomized Set (RS) will consist of all enrolled subjects randomized into the study.
3.5.3
Safety Set
The Safety Set (SS) will consist of all subjects in the RS who have received at least 1 dose of
IMP.
3.5.4
Full Analysis Set
The FAS will consist of all subjects in the RS who received at least 1 dose of IMP, and have at 
least 1 post-Baseline seizure diary.
3.5.5
Per Protocol Set
The Per-Protocol Set (PPS) will consist of subjects in the FAS Population who do not have a 
major protocol deviation impacting the primary efficacy variable.
3.5.6
Other analysis sets
The Pharmacokinetic Per-Protocol Set (PK-PPS) will consist of subjects in the RS who received 
at least 1 dose of IMP who do not have a major protocol deviation impacting the PK variables.
The evaluable population for the PK analysis will consist of those subjects in the PK-PPS for 
whom a sufficient number of samples are available to determine at least 1 PK parameter. At the 
discretion of the pharmacokineticist, a subject may be excluded from this set.

Changes to protocol-defined analyses
The protocol states that all analyses will be based on the randomized treatment. However, the PK 
and safety analyses will be performed on the actual treatment received. 
The Change in time to recovery (protocol, section 4.1.3) will not be analyzed in this study.
The efficacy endpoints will be reported and analyzed in the periods specified in the protocol, and 
also at additional periods if deemed appropriate.
3.10
Definition of study-specific derived variables
3.10.1
Seizure frequency related variables
!
Seizure frequency
Initial Processing of Diary Data
Each seizure code in the clinical database will be mapped to exactly 1 of the following codes 
based on the 1981 International League Against Epilepsy (ILAE) classification: I, IA, IA1, IA2, 
IA3, IA4, IB, IB1, IB2, IC, II, IIA, IIB, IIC, IID, IIE, IIF, or III. 
With regard to cluster seizures, investigator sites are to report the number of cluster episodes 
rather than reporting the estimated number of individual seizures. Therefore, no imputation will 
be applied for the seizure counts corresponding to reports of cluster seizures.
Calculation of Total Seizure Counts by Study Period
The total number of seizures for seizure types IA1 (not IA2-4), IB (i.e. IB1 and IB2), IC (i.e. 
IC1, IC2, and IC3), and the total number of focal seizures (IA1, IB, IC), and the total number of 
seizures for all seizure types (I+II+III) will be calculated across all diary records over the study 
period being summarized.
Calculation of Adjusted Seizure Frequency
Weekly adjusted seizure frequency for seizure types IA1 (not IA2-4), IB (i.e. IB1 and IB2), IC 
(i.e. IC1, IC2, and IC3), and the total number of focal seizures (IA1, IB, IC) will be calculated 
for the period of interest by dividing the number of seizures for each seizure type by the number 
of days for which the diary was completed for each study period, and multiplying the resulting 
value by 7.
The 28-day adjusted seizure frequency will be calculated in a similar way as above.
Calculation of Log-Transformed Values
The above values for each study period of interest will be transformed using the function 
ln(x+1), where ln represents the natural logarithm function.
!
Percent reduction in seizure frequency
Percent reduction from Baseline in seizure frequency to the corresponding evaluation Period will 
be calculated using the following formulae:
Change from Baseline in the weekly adjusted seizure frequency 
Weekly adjusted seizure frequency during the Baseline period  × 100

The change from Baseline is calculated subtracting the weekly adjusted seizure frequency during 
the period of interest from the weekly adjusted seizure frequency during the Baseline period.
The following categories of percent reduction in seizure frequency from Baseline to the
corresponding Treatment Period will be computed: <-25%, -25% to <25%, 25% to <50%, 50% 
to <75%, 75% to <100%, and 100%.
!
XX% Responder Rate in seizure frequency
A subject is defined as a responder if s/he has a reduction in seizure frequency of at least XX% 
from their Baseline seizure frequency. The XX%RRs that will be calculated include, but are not 
limited to 50%, 75%, and will be calculated as follows:
Count of responders during the period
Count of  responders during the period + Count of  non responders during the period × 100
3.10.2
Seizure freedom 
A subject is defined as seizure free over a specific time period if they meet all of the following 
criteria:
1. The subject completed this specific time period.
2. The subject did not have any missing diary days over the time period.
3. The subject did not report any seizure of any type over the time period. Period-specific 
algorithm rules will be added for the seizure freedom evaluation.
!
Seizure-free rate
The seizure-free rate (%) for a specific time period will be calculated using the following 
formula:
Count of seizure free subjects during the period
Count of seizure free subjects during the period + Count of non seizure free subjects during the period × 100
3.10.3
Seizure-free days
The percentage of seizure-free days for a specific time period will be calculated using the 
following formula:
Count of seizure free days during the time interval
Count of days of the time interval will available seizure diary data × 100 
3.10.4
Patient Weighted Quality of Life in Epilepsy Inventory
The Patient Weighted QOLIE-31-P is an adaptation of the original QOLIE-31 (Cramer et al, 
1998). The QOLIE-31-P includes 30 items grouped into 7 multi-item subscales (seizure worry [5 
items], overall quality of life [2 items], emotional well-being [5 items], energy/fatigue [4 items], 
cognitive functioning [6 items], medication effects [3 items], and social function [5 items]) and a 
health status item. The QOLIE-31-P total score, subscale scores, and health status item score are 
calculated according to the scoring algorithm described below, with scores ranging from 0 to 100 
and higher scores indicating better functioning. In addition to these 31 items, the QOLIE-31-P 
includes seven items assessing the degree of “distress” associated with the topic of each subscale 
(ie, distress items) and 1 item asking about the relative importance of each subscale topic (ie, 
prioritization item).

Subscale Scores
As a first step to calculating the subscale scores, the individual responses for the 30 subscale 
items are rescaled to a 0 to 100 scale with higher scores reflects better functioning; the rescaled 
values for each item are defined in Section 13.3. Each subscale score is then calculated by 
summing the rescaled responses for that subscale and dividing by the number of items with a 
non-missing response. A subscale score will be calculated only if at least 50% of the items 
within the subscale are present.
Total Score
Total score is calculated as a weighted sum of the subscale scores based on the weighting in
Section 13.3. Total score will be missing if at least 1 subscale score is missing. Total score will 
range from 0 to 100 with a higher score reflecting better functioning. 
Health Status Item
Responses for the health status item are a multiple of 10 ranging from 0 to 100 with a higher 
score corresponding to a better health status. The health status item response is analyzed without 
rescaling.
Distress Items
Each subscale includes 1 distress item. The response for each distress item is an integer ranging 
from 1 to 5. The response for each distress item will be converted to a 0 to 100 scale (ie, 0, 25, 
50, 75, and 100) with a higher score corresponding to greater distress.
Prioritization Item
The response for each subscale for the prioritization item is an integer ranging from 1 to 7. The 
prioritization ranking is analyzed without rescaling.
3.10.5
Medications
Each medication will be classified as either an AED or a non-AED. Medications recorded on the 
Prior and Concomitant AED case report form (CRF) will be classified as AEDs. Medications 
recorded on the Prior and Concomitant Non-AED CRF can be classified as either AEDs or Non-
AEDs based on the following rules and based on manual review of such medications.
Benzodiazepines taken more than once per week for non-epilepsy indications will generally be 
classified as AEDs. Generally, benzodiazepines taken with a frequency of QD, BID, TID, QID, 
5XD, 6XD, QOD, QAM, or QPM will be classified as AEDs. With regard to PRN use, each 
individual intake of a benzodiazepine is to be recorded on the CRF and the classification of such 
benzodiazepines as an AED will generally be assessed on an individual basis. In general, all 
benzodiazepines will be reviewed during pre-lock meeting to ensure the appropriate 
classification as AEDs or non-AEDs.
Other medications which pharmacologically can be classified as an AED but which were taken 
for non-epilepsy indications may also be classified as AEDs. The classification of such 
medications will be determined during the database pre-lock meeting and prior unblinding. 
There may be medications recorded on the Prior and Concomitant Medications CRF which are 
taken for seizure rescue. These medications will be classified as AEDs. The identification of 
such medications will be based on a manual evaluation of the indication and other CRF fields.

STATISTICAL/ANALYTICAL ISSUES
4.1
Adjustments for covariates
The primary analysis will be conducted using adjustment for the stratification variable; the 
LEV-use factor (3 strata):
1. LEV prior and current use (concomitant use of LEV at study entry).
2. LEV Prior Use Only=History of prior LEV use and must have discontinued 4 weeks prior to 
study entry.
3. LEV Naïve=No history of prior LEV use, and no use at study entry.
4.2
Handling of dropouts or missing data
Missing data will not be imputed with the following exceptions:
Seizure diary:
Seizure frequency will be computed over non-missing diary days as described in Section 3.10; 
missing seizure diary days will not be considered in the calculation of seizure frequency.
Generally, compliance with the daily seizure diary is expected to be high in a refractory 
population and, therefore, the impact of missing diary data is expected to be minimal. However, 
the impact of missing diary data cannot be ruled out, and missing data will be assessed as part of 
the database pre-lock meeting to ensure an acceptable level of compliance with the seizure diary 
across the study population.
For subjects who prematurely discontinue, or have missing diary days, the calculation of the
seizure frequency over a specified period will be based on available seizure diary up to the last
diary entry. This effectively imputes the unobserved seizures after discontinuation with the 
seizure frequency observed prior to discontinuation. 
Times and Dates:
Times and partial dates may be imputed for statistical analyses for specific outcomes according 
to the following rules. Imputed times and dates should not be shown in the listing.
Imputation of Start Times and Partial Start Dates:
!
If only the date is specified and it is the date of the first dose, then use the time of the first 
dose, otherwise, use 00:00.
!
If only the month and year are specified and the month and year of first dose is not the same 
as the month and year of the start date, then use the 1st of the month and 00:00.
!
If only the month and year are specified and the month and year of first dose is the same as 
the month and year of the start date, then use the date and time of first dose.
!
If only the year is specified, and the year of first dose is not the same as the year of the start 
date, then use January 1st and 00:00 of the year of the start date.
!
If only the year is specified, and the year of first dose is the same as the year of the start date,
then use the date and time of the first dose.

4.3
Interim analyses and data monitoring
4.3.1
Safety Review Group
In order to monitor the safety data, a Safety Review Group (SRG) will be established prior to the 
start of the study with the intention of protecting the safety, health, and wellbeing of each 
participating subject. The precise membership, scope, and responsibilities of the SRG are 
described in the SRG Charter. 
The SRG will meet once the first 4 subjects have completed the Transition-to-Outpatient Period 
(Visit 6) or withdrawn from the study before Visit 6. Subsequent meetings will occur when the 
first 10 subjects, the first 16 subjects, and the first 22 subjects have completed Visit 6 or 
withdrawn from the study before Visit 6. Thereafter, SRG meetings will be held on an as 
required/ad hoc basis, in response to emerging data, and at the request of any member of the 
SRG.
The SRG will remain blinded through the first database lock (see Protocol; Section 12.3.3) 
unless emergent safety information requires unblinding of individual drug allocation for optimal 
assessment and response to AEs of concern. At the time of the first database lock, the Study 
Physician(s), clinical pharmacologist, DS representative, biostatistician, and other UCB 
personnel will be unblinded as to all subjects’ treatment allocation at the beginning of the 
Inpatient Period.
4.3.2
Blinded Interim Analysis
An interim analysis will be performed if needed for purposes of planning and designing of future 
studies. If performed, this analysis will be conducted when at least 75% of patients have been 
randomized and completed through the Inpatient Period (completed through Visit 5).
All subjects who have completed through Visit 5 at the time of the data snapshot will be included 
in the interim analysis.
All statistical analyses will be described in detail in a separate interim SAP or appropriate charter 
document.
For the interim analysis, the primary efficacy variable (75%RR) will be analyzed using the 
methods described for the primary efficacy analysis. In addition, seizure-free rate, 50%RR, and 
percent reduction in focal seizure frequency will be analyzed as described for the 
secondary/exploratory analyses.

The 75%RR, Seizure-free rate, and 50%RR variables may also be analyzed using Bayesian 
logistic regression. If Bayesian analysis is peformed, the percent reduction in focal seizure 
frequency from the Baseline will be estimated using Bayesian analysis of variance (ANOVA) 
and/or ANCOVA. For these analyses, posterior medians, 95% credible intervals for the treatment 
effect, and additional posterior probabilities will be presented. Non informative and informative 
priors will be considered, and sensitivity to different prior settings will be assessed. Other  
efficacy variables may also be analyzed in the Bayesian framework.
The following safety data will also be presented:
!
Treatment emergent AEs
!
AEs leading to drop-out or withdrawal
!
SAEs
!
Laboratory assessments out of normal range
!
BPRS
The study will not be terminated early for either efficacy or futility based on the results of this 
interim analysis and therefore, an alpha penalty may not assessed.  At a maximum, an alpha 
penalty of 0.001 may be assessed  on the primary efficacy variable.  
The study is not expected to be stopped due to safety reasons during this interim analysis, since 
there are ongoing quarterly Safety Review Group meetings already planned for this purpose. 
Therefore, no criteria for evaluation of early stopping due to safety are included. 
An unblinded team will be established at both the Sponsor and CRO and will include the 
following roles (all unblinded): Statistician, Statistical Programmer, and Project Lead. All staff 
involved in the conduct of the study, including staff at UCB, the CRO, participating vendors, and 
the participating sites will remain blinded to individual treatment identity and will not be 
informed of the results of the interim analysis until final unblinding.
4.4
Multicenter studies
The data from different centers will be pooled. 
4.5
Multiple comparisons/multiplicity
No adjustments for multiplicity will be made as the statistical analyses will be exploratory in 
nature.
4.6
Use of an efficacy subset of subjects
All efficacy analyses will be performed for the FAS. The primary analysis will be performed for 
the PPS as well. No further efficacy subsets are planned.
4.7
Active-control studies intended to show equivalence
Not applicable.
4.8
Examination of subgroups
Descriptive analysis may be performed by the 3 LEV-use levels for some variables, including, 
but not limited to the primary efficacy variable, and the seizure-freedom.

End of Study Analyses
The database lock and unblinding may occur in a tiered approach, as described in the protocol. 
Details regarding the tiered database lock will be described in the Data Management Plan 
(DMP).  
Data analysis and production of TFLs will occur as follows:
After the final subject has completed through Visit 15 (end of Outpatient Maintenance Period) 
and the corresponding database lock has occurred, all TFLs will be produced and analyses of all 
data at time points through Visit 15 will be considered final.  Note that unblinding of the 
placebo-controlled portion of the study (Visits 3-5) will occur prior to this analysis, as described 
in the protocol and DMP.  TFLs will include all study visits as planned in the SAP.  However, 
only those time points through Visit 15 will be considered final.  TFLs will be annotated with a 
header to display which visits are considered final.
After the final subject has completed through Visit 20 (End of Taper and Safety Follow Up 
Period) and the corresponding database lock has occurred, all TFLs will be produced and 
analyses of all data at time points through Visit 20 will be considered final.  
After the final subject has completed the echocardiogram required at 6 months (±1 month) after 
the last dose, and the corresponding database lock has occurred, the echocardiogram TFLs will 
be produced and considered final.

MEASUREMENTS OF TREATMENT COMPLIANCE
Study drug compliance will be assessed from the day of first IMP administration to the day of 
last dose during the taper period, or up to the end of the outpatient period for the subjects who 
will continue to the open label extension (OLE). Compliance will be calculated as 100 times the 
dose (tablets) taken divided by the planned dose (tablets) that should have been taken. If a 
subject withdraws from the study during a treatment period, their compliance will be calculated 
up to the time that they dropped out. After a subject has dropped out, the compliance should not 
be set to zero. Compliance will be listed and summarized for the SS.
Compliance will be included in the study drug administration listing. In addition, the mean 
compliance will be listed for each subject, for each of the following treatment periods: 1st

EFFICACY ANALYSES
All seizure diary data will be listed for the RS. The summaries will include the statistics for 
continuous or categorical variables as specified in Section 3.1.
For the efficacy analyses the term “by treatment group” corresponds to the UCB0942/Placebo 
group, the UCB0942/UCB0942 group, and the All UCB0942 Subjects group. 
8.1
Statistical analysis of the primary efficacy variable
The primary outcome measure is the 75%RR which is defined as the proportion of subjects with 
a 75% or greater reduction in focal seizure frequency during the 2-week Inpatient Period (as 
defined in Section 3.2.1.2) compared to the Baseline Period. 
The 75%RR will be analyzed using a logistic regression with effects for treatment, for the 3 
levels of LEV use, and the log-transformed Baseline seizure frequency as a continuous covariate. 
The frequency and percentage of 75%RR will be reported with the estimated odds-ratios and 
two-sided Wald 95% CI for UCB0942 versus placebo. 
The primary analysis will be performed for the FAS but also for the PPS.
8.2
Statistical analysis of the secondary efficacy variables
All analyses of the secondary efficacy analyses will be done for the FAS.
Median percent reduction in weekly focal seizure frequency
The percent reduction in focal seizure (Type IA1+IB+IC) frequency from Baseline Period to the 
2-week Inpatient Period will be compared between the UCB0942 and placebo arms using a 
Wilcoxon-Mann-Whitney test. The Hodges-Lehmann non-parametric estimator will be used to 
estimate the median percent reduction in seizures between groups and its corresponding 95% CI 
will be provided. 
Percent reduction in focal seizure frequency from the Baseline Period to the Outpatient 
Maintenance Period and On-UCB0942 Overall will be assessed using summary tables by 
treatment group. 
The percent reduction in focal seizure frequency from the Baseline Period to the 2-week 
Inpatient Period, the Outpatient Maintenance Period and the On-UCB0942 Overall period will be 
presented graphically with box-plots.
75%RR on percent reduction in weekly focal seizure frequency
This score will be calculated during the last 4 weeks of the Outpatient Maintenance Period, and 
On-UCB0942 Overall, and will be compared to the Baseline Period by treatment group using 
summary statistics.

Seizure free rate
The seizure free rate for the 2-week Inpatient Period will be analyzed using a logistic regression 
with effects for treatment and log-transformed Baseline seizure frequency as a continuous 
covariate, if applicable. Odds-ratio of UCB0942 versus placebo groups and its 95% CIs will be 
estimated. 
The seizure freedom will also be evaluated by treatment group for the last 4 weeks of the 
Outpatient Period and for the On-UCB0942 Overall period using summary statistics. 
Percentage of seizure free days
The percentage of seizure free days will be assessed during the 2-week Inpatient and the 
Outpatient Maintenance periods using summary statistics by treatment group. 95% Hodges-
Lehmann CIs for the median will be estimated.
8.3
Analysis of exploratory efficacy variables
All analyses of the exploratory efficacy analyses will be done for the FAS.
50%RR on percent reduction in weekly focal seizure frequency 
The 50%RR on percent reduction in weekly focal seizure frequency for the 2-week Inpatient 
Period (see Section 2.2.1.3) will be analyzed only for the FAS using a logistic regression with 
effects for treatment, for the 3 levels of LEV-use, and the log-transformed Baseline seizure 
frequency as a continuous covariate. The 50%RR at the Outpatient Maintenance Period will be 
summarized by treatment group.
Median seizure frequency by focal seizure type
An analysis of covariance (ANCOVA) will be performed on the log-transformed weekly seizure 
frequency during the 2-week Inpatient Period. Specifically, ln(1+weekly seizure frequency 
during the 2-week Inpatient Period) will be modeled with treatment group as factor and 
ln(1+weekly seizure frequency during the Baseline Period) as covariate. Contrasts will be 
estimated to compare UCB0942 to placebo results observed. Transformation of efficacy data 
could be envisaged given the data distribution. This analysis will be repeated for all the subtypes 
of focal seizures (Type IA1, IB, IC, and disabling [IB+ IC]).
The seizure frequency for the focal seizures (Type IA1+ IB +IC) and focal seizure subtypes 
(Type IA1, IB, IC, and disabling [IB+ IC]) will also be summarized by treatment group and 
UCB0942 Overall for the following study periods: Baseline, 1st Inpatient Week, 2nd Inpatient 
Week, 3rd Inpatient Week, 2-week Inpatient, Outpatient Maintenance Period, and On-UCB0942 
Overall.
The mean 28-day adjusted seizure frequency by focal seizure subtype (Type IA1, IB, IC, and 
disabling [IB+ IC]) will be displayed graphically as stacked bar charts for the following study 
periods:  Baseline, 1st Inpatient Week, 2nd Inpatient Week, 3rd Inpatient Week, 2-week Inpatient,
Outpatient Maintenance Period, and On-UCB0942 Overall.  This will also be presented by

Change in seizure severity
Seizure severity is calculated as the percentage of seizures that are type IC out of the total 
number of focal seizures during a given period. Change from Baseline in seizure severity is the 
seizure severity in the period of interest minus the seizure severity during the 2-week prospective 
baseline period. Seizure severity and its change from baseline will be listed and summarized by 
treatment group for the 2-week Inpatient and Outpatient Maintenance Periods.  For subjects not 
experiencing IC seizures during the observed period, severity is considered to be 0%.
Seizure severity questionnaire
Changes in SSQ will be summarized by treatment group for the Inpatient Period (V3, 4, 5), the 
Outpatient Period (V10, 15) and for the Tapering and SFU periods (V15, 17, 18, 20) using 
summary statistics.  Mean change from baseline in SSQ total and subscores will be presented 
graphically.
The SSQ total score (TS) is derived using the algorithm in Appendix x.
Quality of life
The observed values, and changes from Baseline for the QOLIE-31-P total score and the 
subscales will be listed for all subjects for visits 3, 10, 12, 15, 17. The prioritization item will be 
listed separately.
The QOLIE-31-P change from Baseline will be summarized by treatment group using
descriptive statistics for visits 10, 12, 15, 17.
The QOLIE-31-P mean change from Baseline for the total score and the sub-scores will be 
presented in line plots with 95% Hodges-Lehmann CIs for the whole study period.
Exploratory analyses for efficacy
Median 28-day seizure frequency by focal seizure type: An analysis of covariance (ANCOVA) 
will be performed on the log-transformed weekly seizure frequency during the 2-week Inpatient 
Period. Specifically, ln(1+weekly seizure frequency during the 2-week Inpatient Period) will be 
modeled with treatment group as factor and ln(1+weekly seizure frequency during the Baseline 
Period) as covariate. Contrasts will be estimated to compare UCB0942 to placebo results 
observed. Transformation of efficacy data could be envisaged given the data distribution. This 
analysis will be repeated for all the subtypes of focal seizures (Type IA1, IB, IC, and disabling 
[IB+ IC]).
The seizure frequency for the focal seizures (Type IA1+ IB +IC) and focal seizure subtypes 
(Type IA1, IB, IC, and disabling [IB+ IC]) will also be summarized by treatment group and 
UCB0942 Overall for the following study periods: Baseline, 1st Inpatient Week, 2nd Inpatient 
Week, 3rd Inpatient Week, 2-week Inpatient, Outpatient Maintenance Period, and On-UCB0942 
Overall.

PHARMACOKINETICS 
All PK analyses will be performed for the PK-PPS.
9.1
Non compartmental PK analysis
Plasma concentrations of UCB0942, 
 will be
determined from blood samples obtained in the study, during the Titration and Maintenance 
Periods in order to investigate the population PK of UCB0942 and its major metabolites.
Individual concentrations of UCB0942,
 will be listed 
by treatment group for the FAS and will include the actual and nominal sampling times and the 
deviation between them. All deviations will be calculated relative to the IMP administration.
Individual concentrations will be summarized by treatment group, and sampling times for the 
PK-PPS using n, mean, median, SD, minimum, maximum, geometric mean, and geoCV and 95%
CI (assuming log-normally distributed data). This table will be repeated for UCB0942,
.
The following plots will be produced for UCB0942,
for the PK-PPS:
!
All individual concentration time profiles will be displayed graphically on a linear and semi-
logarithmic scale.
!
Spaghetti plots with the individual plasma concentrations over time profiles for each
treatment group will be displayed for all subjects (linear and semi-logarithmic scale).
!
Geometric mean profiles (with and without corresponding lower and upper limit of the 95%
CI) for the treatment groups will be displayed on the same plot.
The figures will include the LLOQ on the semi-logarithmic plots only.
The following PK parameters will be calculated for UCB0942 and its metabolites:
!
AUCτ:
area under the plasma concentration-time curve over a dosing interval, as
determined using the linear trapezoidal rule.
!
Cmax:
maximum observed plasma concentration.
!
tmax:
time of Cmax.
!
t½:
apparent terminal elimination half-life, reported hours, as determined via simple 
linear regression (slope = -λz) of natural log (ln) concentration vs time for data points in the 
terminal phase of the concentration-time curve. t½ is calculated as ln(2)/λz.
!
Ctrough:
measured concentration at the end of a dosing interval at steady state.

The PK parameters will be calculated via NCA methods using Phoenix WinNonlin (version 6.2 
or higher) using the actual sampling times by PRA with UCB’s supervision. Actual sampling 
times relative to dosing rather than nominal times will be used in the calculation of all derived 
PK parameters.
The PK parameters of UCB0942 and its metabolites will be listed and summarized using the 
following descriptive statistics: n, geometric mean, lower and upper 95% CI, geometric CV, 
arithmetic mean, SD, median, and minimum and maximum values. 
Graphical outputs over time will be produced on the trough plasma drug concentrations.
9.2
Population pharmacokinetics
If appropriate, a population PK analysis of UCB0942 and identified active metabolites, will be 
performed using non-linear mixed effects modeling within the population software (NONMEM) 
aimed at identifying relevant covariates (demographic variables, other AEDs). The population 
PK analysis will be performed by UCB and will be described in a separate data analysis plan 
(DAP), and it will be reported in a separate report.
9.3
Pharmacokinetic/pharmacodynamic analysis 
Exploratory population PK-PD analysis may be performed if needed to characterize the 
relationship between exposure to UCB0942 and the clinical and/or safety clinical outcome. A 
separate DAP will describe the analysis, which will be reported in a separate report.
10
SAFETY ANALYSES
10.1
Extent of exposure
All study drug administration information will be listed by treatment group. 
The duration of study drug will be calculated as the date of last dose of study drug minus the date 
of first dose of study drug plus 1 day. The duration will be listed for each subject for the 
following treatment periods: 1st Inpatient Week, 2nd Inpatient Week, 3rd Inpatient Week, 
Outpatient Maintenance Period, Tapering Period, SFU Period, UCB0942 Overall.
The duration of study drug exposure will be calculated as the date of last dose of study drug 
during the Period of interest minus the date of first dose of study drug plus 1 day. 
The duration of study drug exposure (in days) will be summarized by treatment group. The 
exposure for the subjects randomized to placebo will be summarized separately for the Placebo 
and UCB0942 exposure. The number and percentage of subjects with the following categories of 
durations of study drug exposure will also be summarized: ≤1 week, >1 to ≤2 weeks, >2 to ≤4 
weeks; 4 to ≤6 weeks; >6 to ≤8 weeks; >8 to ≤9 weeks; >9 to ≤11 weeks; >11 weeks.
10.2
Adverse events
Adverse events will be recorded from the time informed consent is granted until study 
completion or study termination (end of the SFU period). All AEs will be coded using the latest 
available version of MedDRA and will be categorized by intensity (mild/moderate/severe). 
Listings will be provided for all AEs, SAEs, AEs leading to tapering, AEs leading to withdrawal, 
and AEs leading to death by treatment group for the SS.

A treatment-emergent adverse event (TEAE) is defined as any event not present prior to the 
initiation of the first dose of study treatment or any unresolved event already present before 
initiation of the first dose that worsens in intensity following exposure to the treatment.
The number and percentage of subjects who experience TEAEs will be summarized by SOC and 
PT, and by treatment group. In the same table, the number and percentage of subjects will be 
summarized by the following treatment periods as defined in Section 3.2.1.2: Placebo Only, 
UCB0942 Titration, UCB0942 Maintenance, UCB0942 Taper, and On-UCB0942 Overall.
The following tabular summaries will be presented for the SS:
!
Incidence of AEs - Overview 
!
Incidence of TEAEs 
!
Incidence of Serious TEAEs 
!
Incidence of TEAEs by Relationship
!
Incidence of SAEs by Relationship

!
Incidence of Non-Serious TEAEs above the Threshold of 5% of Subjects by Relationship
Where dates are missing or partially missing, AEs will be assumed to be treatment-emergent, 
unless there is clear evidence (through comparison of partial dates, see Section 4.2) to suggest 
that the AE started prior to the first dose of study treatment.
Summary tables will contain counts of subjects, percentages of subjects in parentheses and the 
number of events where applicable. A subject who has multiple events in the same SOC and PT 
will be counted only once in the subject counts but all events will be included.
In summaries including relationship to study treatment, the following relationships will be 
summarized: ‘Not related’, ‘Related’. Subjects who experience the same event multiple times 
will be included in the most related category. Events with missing relationship will be considered 
as ‘Related’ to the last given study product for summary purposes but recorded as missing in the 
listings.
In summaries including intensity, the following intensity categories will be summarized: ‘Mild’, 
‘Moderate’, ‘Severe’. Subjects who experience the same event multiple times will be included in 
the most severe category. Events with missing intensity will be considered as ‘Severe’ events for 
summary purposes but recorded as missing in the listings.

Clinical laboratory evaluations
All summaries of laboratory parameters will only summarize parameters planned based on the 
protocol; however, both planned and unplanned laboratory parameters will be provided in 
subject data listings.
Observed laboratory data (chemistry, hematology, urinalysis measurements as listed in Table 8‒
1), and changes from Baseline for numeric parameters will be listed and summarized for the SS
by treatment group. The change from the last pre-UCB0942 administration measurement will be 
listed and summarized for the placebo group. Laboratory values will be grouped according to 
the laboratory function panel shown in Table 8‒1 and flagged as high or low based on the
possibly clinically significant treatment emergent (PCST) criteria, if applicable. The number and 
percentage of subjects with a PCST low or high value will be summarized by treatment group. In 
the same table, the number and percentage of subjects will be summarized by the following 
treatment periods as defined in Section 3.2.1.2: Placebo Only, UCB0942 Titration, UCB0942
Maintenance, UCB0942 Taper, and UCB0942 Overall.
Possibly clinically significant treatment emergent criteria are based on FDA Division of 
Neuropharmacologic Drug Products guidelines with some UCB-defined additions (Section 13.2).
For the laboratory parameters that are identified in Table 8‒1, the change in category (normal 
range: low, normal, high) at the end of Maintenance from Baseline will be presented in shift 
tables. 
Additional laboratory tests (including serology –only at Screening-, drugs and alcohol,
pregnancy) performed will be listed, but will not be summarized.

Urinalysis
Qualitative urine parameters are generally reported by a descriptive score, which differs among laboratories. For data analysis 
purpose, a four-point scale is used. Five-point, six-point, or seven-point scales will be collapsed into a four-point scale first. A value is 
considered possibly clinically significant treatment-emergent abnormal if an upward shift of at least 2 degrees from the baseline 
occurs under investigational treatment. To collapse the results in a five-point scale into a four-point scale, the lowest 2 positive results 
will be combined (see example below). For results reported with a scale of more than five-point, please consult your study physician 
for how to collapse into four-point scale.

QOLIE-31-P total and subscale score calculations
The following outlines the calculation of the subscale scores for the QOLIE 31 P. The rescaled responses are provided for each item. 
The subscale scores are calculated by summing the rescaled responses for that subscale and dividing by the number of items with a 
non-missing response. Note that the divisors shown assume that all items for each subscale have a response; the divisor will differ if 
there are missing responses. A subscale score will be calculated only if at least 50% of the items within the subscale are present.

Section 6.3
Prior and concomitant medications
The medications will be classified as AEDs or non-AEDs in the CRF, and will be reviewed
during the DEM. Prior and concomitant non-AED medications will be listed for the SS by
treatment group and by WHODD Anatomical Main Group [Level 1], Therapeutic Subgroup
[Level 2], PT and reported term. This listing will be repeated for all AED medications.
Any non-coded terms will report Level 1 and Level 2 as UNCODED in the listing.
Prior medication definition
If a subject takes a medication between the Screening date and before the date of study drug
administration, this medication will be classified as ‘prior medication’. With this definition, any
medication recorded that has been taken for at least 1 day and has been stopped before the
Inpatient Period will be considered as prior.
Concomitant medication definition
Prior medication not stopped before the study drug administration date will be classified as
‘concomitant medication’. Medication will be labeled as ‘concomitant medication’ when the start
date is between the date (including the date) of study drug administration and the final study visit
or, in case of early termination, on the date of the subject’s last visit. With this definition, any
medication that has been taken for at least 1 day during the study period will be considered as
concomitant.
Was changed to
The medications will be classified as AEDs or non-AEDs based on coded terms.  The list of 
coded terms considered AEDs will be finalized prior to database lock and unblinding.  Prior and 
concomitant non-AED medications will be listed for the SS by treatment group and by WHODD
Anatomical Main Group [Level 1], Therapeutic Subgroup [Level 2], PT and reported term. This 
listing will be repeated for all AED medications.
Any non-coded terms will report Level 1 and Level 2 as UNCODED in the listing.
Prior medications include any medications that started prior to the date of first dose of study 
drug.   Concomitant medications are medications taken at least one day in common with the 
study medication dosing period. Medications may be both prior and concomitant. Past

Section 8.3 Analysis of Exploratory Efficacy Variables
Median seizure frequency by focal seizure type
An analysis of covariance (ANCOVA) will be performed on the log-transformed weekly seizure
frequency during the 2-week Inpatient Period. Specifically, ln(1+weekly seizure frequency
during the 2-week Inpatient Period) will be modeled with treatment group as factor and
ln(1+weekly seizure frequency during the Baseline Period) as covariate. Contrasts will be
estimated to compare UCB0942 to placebo results observed. Transformation of efficacy data
could be envisaged given the data distribution. This analysis will be repeated for all the subtypes
of focal seizures (Type IA1, IB, IC).
The seizure frequency for the focal seizures (Type IA1+ IB +IC) and focal seizure subtypes
(Type IA1, IB, IC) will also be summarized by treatment group and UCB0942 Overall for the
following study periods: Baseline, 1st Inpatient Week, 2nd Inpatient Week, 3rd Inpatient Week,
2-week Inpatient, Outpatient Maintenance Period, and On-UCB0942 Overall.
Change in seizure severity
The change in seizure severity is calculated as the change from Baseline in the percentage of
seizures that are type IC out of the total number of focal seizures. It will be listed and
summarized by treatment group for the 2-week Inpatient and Outpatient Maintenance Periods.

periods will be presented as a bar chart:  1st Inpatient Week, 2nd Inpatient Week, 3rd Inpatient 
Week, 2-week Inpatient, Outpatient Maintenance Period, and On-UCB0942 Overall.    This will 
also be presented by subject
Change in seizure severity
Seizure severity is calculated as the percentage of seizures that are type IC out of the total 
number of focal seizures during a given period. Change from Baseline in seizure severity is the 
seizure severity in the period of interest minus the seizure severity during the 2-week prospective 
baseline period. Seizure severity and its change from baseline will be listed and summarized by 
treatment group for the 2-week Inpatient and Outpatient Maintenance Periods.  For subjects not 
experiencing IC seizures during the observed period, severity is considered to be 0%.
Seizure severity questionnaire
Changes in SSQ will be summarized by treatment group for the Inpatient Period (V3, 4, 5), the 
Outpatient Period (V10, 15) and for the Tapering and SFU periods (V15, 17, 18, 20) using 
summary statistics.  Mean change from baseline in SSQ total and subscores will be presented 
graphically.
The SSQ total score (TS) is derived using the algorithm in Appendix x.
Quality of life
The observed values, and changes from Baseline for the QOLIE-31-P total score and the 
subscales will be listed for all subjects for visits 3, 10, 12, 15, 17. The prioritization item will be 
listed separately.
The QOLIE-31-P change from Baseline will be summarized by treatment group using
descriptive statistics for visits 10, 12, 15, 17. 
The QOLIE-31-P mean change from Baseline for the total score and the sub-scores will be 
presented in line plots with 95% Hodges-Lehmann CIs for the whole study period.
Exploratory analyses for efficacy
Median 28-day seizure frequency by focal seizure type: An analysis of covariance (ANCOVA) 
will be performed on the log-transformed weekly seizure frequency during the 2-week Inpatient 
Period. Specifically, ln(1+weekly seizure frequency during the 2-week Inpatient Period) will be 
modeled with treatment group as factor and ln(1+weekly seizure frequency during the Baseline 
Period) as covariate. Contrasts will be estimated to compare UCB0942 to placebo results 
observed. Transformation of efficacy data could be envisaged given the data distribution. This

analysis will be repeated for all the subtypes of focal seizures (Type IA1, IB, IC, and disabling 
[IB+ IC]).
The seizure frequency for the focal seizures (Type IA1+ IB +IC) and focal seizure subtypes 
(Type IA1, IB, IC, and disabling [IB+ IC]) will also be summarized by treatment group and 
UCB0942 Overall for the following study periods: Baseline, 1st Inpatient Week, 2nd Inpatient 
Week, 3rd Inpatient Week, 2-week Inpatient, Outpatient Maintenance Period, and On-UCB0942 
Overall.
Exploratory analysis will be performed on the seizure count and SSQ data collected during the 
tapering and SFU periods. The focal seizure frequency will be summarized by treatment group 
for the tapering and SFU periods. 
The relationship between QOLIE-31-P parameters and efficacy parameters will be evaluated 
graphically. Plots may include, but are not limited to, scatterplots of the QOLIE-31-P subscales 
and total score versus the focal seizure reduction at the end of the Outpatient Maintenance 
Period. This plot will be repeated for the 75%RR.
All video data recorded in the CRF will be listed.
