Study Protocol Title 
A multicenter, uncontrolled, open-label study to evaluate the safety and tolerability of intravenous 
perampanel as substitute for oral tablet in subjects with partial onset seizures (including secondarily 
generalized seizures) or primary generalized tonic-clonic seizures 
Sites 
Japan, approximately 15 sites 
Study Period and Phase of Development 
Study Period:  October 2018 to April 2020 (planned) 
Phase 2 
Objectives 
Primary Objective: 
To evaluate the safety and tolerability of 30-minute intravenous infusions of perampanel after switching 
from oral perampanel (8 to 12 mg/day) as an adjunctive therapy in subjects with partial-onset seizures 
(POS) with or without secondarily generalized seizures or primary generalized tonic-clonic (PGTC) 
seizures 
Secondary Objectives: 
• To evaluate the plasma concentration of perampanel before and after switching from oral 
perampanel to 30-minute intravenous infusions of perampanel 
• To evaluate the seizure frequency before and after switching from oral perampanel to 30-minute 
intravenous infusions of perampanel 
Study Design 
This is a multicenter, uncontrolled, open-label study in subjects with POS with or without secondarily 
generalized seizures or PGTC seizures.  This study will consist of 3 phases:  the Pretreatment Phase, 
Treatment Phase, and Follow-up Phase. 
During the Pretreatment Phase, subjects will be screened and assessed for eligibility to participate in 
the study.  Subject informed consent/assent will be obtained before the screening, after which protocol 
eligibility will be established on any day from Day –28 to Day –7.  Eligible subjects must be on a 
stable dosage (8 to 12 mg/day) of oral perampanel as an adjunctive therapy with 1 to a maximum of 3 
marketed concomitant antiepileptic drugs (AEDs) for at least 28 days before the first dose of the study 
drug (ie, intravenous infusion of perampanel).  Eligible subjects will return to and remain onsite (be 
“hospitalized”) 1 day before switching from oral perampanel to intravenous infusion of perampanel (ie, 
on Day –1 [Visit 2]). 
During the Treatment Phase, hospitalized subjects will be switched from oral perampanel to intravenous 
infusion of perampanel at a dose equivalent to the oral perampanel dose.  Subjects will receive 30-
minute intravenous infusions of perampanel once a day for 4 days under inpatient conditions. 
Afterwards, the subject must be switched back to oral perampanel at the equivalent daily dose of the

intravenous infusion of perampanel. 
If subjects cannot continue intravenous infusion of perampanel for any reason(s), they must discontinue 
the study. 
Subjects will be discharged from the hospital the day after the last intravenous infusion of perampanel, 
and treatment must be switched back to their original dose of oral perampanel.  The assessments at the 
Follow-up Visit will be conducted 7 days (allowance window: +7 days) after the last intravenous 
infusion of perampanel. 
The study design is shown below.

Assessments 
Safety Assessments 
Safety assessments will consist of monitoring and recording all adverse events (AEs), clinical 
laboratory evaluations (biochemistry, hematology, urinalysis), vital signs, weight, 12-lead 
electrocardiogram (ECG), and physical examinations. 
Efficacy Assessments 
Seizure diaries will be used to collect all seizure counts and types. 
Pharmacokinetic Assessments 
The plasma concentration of perampanel will be determined. 
Bioanalytical Method 
The plasma concentration of perampanel will be measured by a validated liquid chromatography with 
tandem mass spectrometry (LC/MS/MS) assay. 
Statistical Methods 
Study Endpoints 
The safety endpoints are AEs, clinical laboratory tests (biochemistry, hematology, and urinalysis), vital 
signs, weight, and 12-lead ECG. 
The efficacy endpoint is the seizure frequency per day in each of the 3 phases (Pretreatment Phase, 
Treatment Phase, and Follow-up Phase).  Seizure frequency per day will be derived from the 
information recorded in the subject diaries. 
The pharmacokinetic endpoint is the plasma concentration of perampanel.

All observed data will be reported with no adjustments for missing data. 
Analysis Sets 
The Safety Analysis Set is the group of subjects who received at least 1 intravenous infusion of 
perampanel. 
The Efficacy Analysis Set is the group of subjects who received at least 1 intravenous infusion of 
perampanel and had at least 1 postdose efficacy measurement. 
The Pharmacokinetic Analysis Set is the group of subjects who received at least 1 intravenous infusion 
of perampanel and had at least 1 evaluable measurement of plasma perampanel concentration. 
Efficacy Analyses 
The efficacy analyses will be performed on the Efficacy Analysis Set.  The seizure frequency per day 
for each of the 3 phases (Pretreatment Phase, Treatment Phase, and Follow-up Phase) will be 
summarized using descriptive statistics (eg, mean, SD, median, minimum, and maximum).  The 
seizure frequency per day from the Pretreatment Phase to the Follow-up Phase for each subject will be 
displayed using a spaghetti-plot. 
Pharmacokinetic Analyses 
The PK analyses will be performed on the Pharmacokinetic Analysis Set using the plasma 
concentrations of perampanel.  Summary statistics for the plasma concentrations will be obtained by 
sampling time point and dose.  The plasma concentrations of perampanel before and after switching 
from oral tablet to intravenous infusion will be plotted.  A similar analysis may be conducted using 
dose-normalized plasma concentration data. 
Safety Analyses 
The safety analyses will be performed on the Safety Analysis Set.  Safety data will be summarized 
using descriptive statistics (eg, n, mean, SD, median, minimum, and maximum for continuous variables; 
n [%] for categorical variables).  Safety variables include AEs, clinical laboratory parameters 
(biochemistry, hematology, and urinalysis), vital signs, weight, and 12-lead ECG results. 
Interim Analysis 
No interim analysis is planned for this study. 
Sample Size Rationale 
This is an uncontrolled, open-label study for the safety evaluation of intravenous infusion of perampanel 
and the sample size (20 subjects) is not based on statistical power considerations, but rather on 
feasibility.  It is considered that a sufficient number of subjects will be obtained for the safety 
evaluation of intravenous infusion of perampanel if the sample size is 20.

This informed consent should be given by means of a standard written statement, written in 
nontechnical language.  The subject or the subject’s legally acceptable representative should 
understand the statement before signing and dating it and will be given a copy of the signed 
document.  If a subject is unable to read or if a legally acceptable representative is unable to 
read, an impartial witness should be present during the entire informed consent discussion.  
After the ICF and any other written information to be provided to the subjects is read and 
explained to the subject or the subject’s legally acceptable representative, and after the subject 
or the subject’s legally acceptable representative has signed and personally dated the ICF, the 
witness should sign and personally date the consent form.  The subject will be asked to sign 
an ICF before any study-specific procedures are performed.  No subject can enter the study 
before his/her informed consent has been obtained. 
If an underage subject is able to understand participation in the study, the investigator should 
explain the nature of the study and other information to the subject with the ICF or an informed-
assent document prepared separately from the ICF, and should obtain the written informed 
consent/assent.  In such cases, the written informed consent for the subject’s participation in 
the study must be obtained from the subject’s legally acceptable representative (ie, an 
individual who exercises parental rights over the subject). 
If a subject is unable to give a written informed consent/assent, the investigator should confirm 
that the subject has orally consented to the subject’s participation in the study, and must obtain 
the written informed consent from the subject’s legally acceptable representative, and record it 
in the ICF. 
An unsigned copy of an IRB-approved ICF and an informed-assent document must be prepared 
in accordance with J-GCP and other applicable regulations.  Each subject must sign an 
approved ICF/informed assent form before study participation.  The form must be signed and 
dated by the appropriate parties.  The original, signed ICF/informed assent form for each 
subject will be verified by the sponsor and kept on file according to the local procedures at the 
site. 
The subject or the subject’s legally authorized representative should be informed in a timely 
manner if new information becomes available that may be relevant to the subject’s willingness 
to continue participation in the study.  The communication of this information should be 
documented.

7. INTRODUCTION 
7.1  Indication 
Epilepsy is a common serious neurological disorder with an overall prevalence of 0.5% to 1%.  
Epilepsy is characterized by the spontaneous recurrence of seizures and requires long term, 
often life-long pharmacological management.  There are 3 major types of clinical seizures: 
generalized, partial (focal), and unclassified seizures.  The most frequent type is partial-onset 
seizures (POS). 
Patients suffering from POS often have poor seizure control.  Uncontrolled seizures lead to a 
wide variety of medical consequences (eg, severe trauma due to seizures, sudden death, 
depression, or intermittent psychotic disorders).  In addition, uncontrolled seizures lead to 
significant lifestyle limitations and social handicaps (eg, loss of driving privileges, difficulties 
getting and maintaining a job). 
Like other types of seizures, primary generalized tonic-clonic (PGTC) seizures are caused by 
a paroxysmal, uncontrolled discharge of cerebral cortical neurons, leading to neurologic 
dysfunction.  Unlike most other types of seizures, however, this cerebral hyperactivity is not 
confined to a localized area, but extends to the entire brain.  The onset of PGTC seizures is 
age-related and typically starts in older children, adolescents, and young adults.  PGTC 
seizures are associated with an increased risk of injury and death.  Therefore, effective control 
of PGTC seizures is necessary to reduce epilepsy-related morbidity and mortality. 
7.1.1  Current Drug Treatment 
In the guidelines for the drug treatment of adult patients with epilepsy by the Japan Epilepsy 
Society, carbamazepine and valproic acid are recommended as the first-line drugs for POS and 
generalized seizures, respectively. 
Intravenous formulations of levetiracetam and fosphenytoin sodium hydrate are the only 
marketed drugs which have an indication for short-term replacement therapy when oral 
administration is temporarily infeasible (eg, in cases of patients undergoing surgical procedures, 
experiencing difficulty swallowing, suffering from consciousness disturbance, or acute 
gastrointestinal disorders). 
7.1.2  E2007 
E2007/perampanel is a first-in-class noncompetitive and highly selective α-amino-3-hydroxy-
5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist that was discovered and 
developed by Eisai. 
Perampanel was approved for marketing as an adjunctive therapy for the treatment of POS with 
or without secondarily generalized seizures in patients aged 12 years and older in Europe and 
the United States in 2012, and in subsequently more than 59 countries.  Perampanel was also 
approved for marketing as an adjunctive therapy for the treatment of PGTC seizures in patients

with epilepsy aged 12 years and older in Europe and the United States in 2015.  In Japan, the 
above 2 indications were approved in March 2016.  Furthermore, perampanel was approved 
for marketing as a monotherapy for the treatment of POS with or without secondarily 
generalized seizures in patients aged 12 years and older in the United States in 2017.  In 
addition, Eisai applied for approval in the United States to expand the indications of adjunctive 
therapy for the treatment of POS with or without secondarily generalized seizures and PGTC 
seizures in patients aged 2 years and older in 2018. 
Depending on the mechanism of action, existing antiepileptic drugs (AEDs) are divided into 2 
groups, the first of which decrease neuronal excitation, and the second of which enhance 
inhibition.  Major target sites for AEDs are blockage of voltage-operated sodium channels or 
calcium channels, regulation of neuronal transmitter release, inhibition of glutamatergic neural 
transmission, and facilitation of gamma-aminobutyric acid (GABA)-ergic neurotransmission.  
Current major AEDs are speculated to have a selective or mixed action on these targets.  
Perampanel is the only available drug showing noncompetitive and selective antagonism to 
AMPA receptors. 
Further detailed information on perampanel including the data of the nonclinical and clinical 
studies that have been completed so far are provided in the Investigator's Brochure. 
7.2  Study Rationale 
In advance of this study, Eisai conducted a survey that aimed to investigate the needs of 
antiepileptic-injection use among epileptologists, and the results suggested that a need for 
antiepileptic-injection use exists for patients for whom it is temporarily not feasible to receive 
oral AEDs due to undergoing surgical procedures or other reasons. 
Perampanel is the only available noncompetitive and selective AMPA receptor antagonist.  
For that reason, when patients cannot temporarily receive a safe and effective dose of oral 
perampanel, and are forced to switch to another oral AED, risks such as poor tolerability and 
seizure control are likely to result for the patients.  Therefore, the development of a 
perampanel intravenous formulation to be used as an alternative to the oral formulation is 
significant. 
Thus, conducting this study, which aims to evaluate the safety and tolerability, as well as the 
pharmacokinetics and efficacy of intravenous infusion of perampanel as a substitute for oral 
perampanel, is considered appropriate.

8. STUDY OBJECTIVES 
8.1  Primary Objective 
The primary objective of this study is to evaluate the safety and tolerability of 30-minute 
intravenous infusions of perampanel after switching from oral perampanel (8 to 12 mg/day) as 
an adjunctive therapy in subjects with POS with or without secondarily generalized seizures or 
PGTC seizures. 
8.2  Secondary Objectives 
The secondary objectives of this study are: 
• 
To evaluate the plasma concentration of perampanel before and after switching from oral 
perampanel to 30-minute intravenous infusions of perampanel 
• 
To evaluate the seizure frequency before and after switching from oral perampanel to 30-
minute intravenous infusions of perampanel

from oral perampanel to intravenous infusion of perampanel (ie, on Day –1 [Visit 2]). 
9.1.2  Treatment Phase 
The Treatment Phase is defined as the period beginning at the start of intravenous infusion of 
perampanel on Day 1 to immediately before the oral perampanel administration on Day 5. 
Hospitalized subjects will be switched from oral perampanel on Day 1 to intravenous infusion 
of perampanel at a dose equivalent to the oral perampanel dose.  Subjects will receive 30-
minute intravenous infusions of perampanel once a day for 4 days under inpatient conditions 
(Days 1 through 4). 
Subjects will be discharged from the hospital the day after the last intravenous infusion of 
perampanel (ie, Day 5), and treatment must be switched back to their original dose of oral 
perampanel. 
If subjects cannot continue intravenous infusion of perampanel for any reason(s), they must 
discontinue the study. 
9.1.3  Follow-up Phase 
The Follow-up Phase is defined as the period after switching back to oral perampanel 
administration. 
The assessments at the Follow-up Visit will be conducted 7 days (allowance window: +7 days) 
after the last intravenous infusion of perampanel. 
9.2  Discussion of Study Design, Including Choice of Control Groups 
Study Design 
This study was designed to be conducted as an open-label, uncontrolled study, as with the 
Japanese study of levetiracetam injection (Inoue Y, et al., 2014), for which the indication as a 
substitute for oral formulation has been approved, in patients with epilepsy taking perampanel 
oral formulation as an adjunctive therapy with other AED(s) to evaluate the safety, tolerability, 
pharmacokinetics, and efficacy when perampanel oral formulation is temporarily replaced with 
perampanel injection. 
Doses of the Study Drug 
Perampanel oral formulation has been approved for the indication as an adjunctive therapy 
with other AED(s) for POS with or without secondarily generalized seizures and PGTC 
seizures, in patients with epilepsy aged 12 years or older, and is used at maintenance doses of 
8 to 12 mg/day. 
In this study, with a view to obtain approval for the indication as a substitute for perampanel 
oral formulation, the doses of the study drug (perampanel injection) are set to the same levels 
(8 to 12 mg/day) as the maintenance doses of perampanel oral formulation taken for at least 28

days before starting administration of the study drug. 
Duration of Study Drug Administration 
The duration of study drug administration is set at 4 days. 
A review of the data on the prescription of levetiracetam intravenous infusion formulation, 
approved as a substitute for oral formulation (Medical Data Vision Co., Ltd.; Review period: 
November 2016 to October 2017), demonstrated that the mean duration of administration was 
4.8 days, and the percentage of patients with an administration duration of 4 days or shorter 
was 73.1% (7688/10510 patients). 
In consideration of feasibility, this study will be conducted not only in inpatients, but also in 
patients who will be able to be admitted to the hospital to participate in the study.  Because 
an unnecessarily prolonged hospital stay may lead to a disadvantage for these patients, the 
duration of study drug administration is set at 4 days, as a duration of administration for which 
the safety of the study drug can be evaluated appropriately, with reference to the duration of 
administration of the Japanese study of other antiepileptic injections (Inoue Y, et al., 2014). 
Time of Study Drug Administration 
In the United States, a clinical pharmacology study (E2007-A001-050 study, hereinafter the 
“Study 050”) was conducted in Japanese and non-Japanese healthy subjects to evaluate 
bioavailability of a single 12 mg dose of perampanel for 3 intravenous infusion durations (for 
30 minutes [n=20], 60 minutes [n=20], and 90 minutes [n=8]) relative to a single 12 mg 
perampanel oral tablet.  As a result, it was demonstrated that the AUC after intravenous 
administration for 30 minutes and 60 minutes was within the range of the criteria for 
bioequivalence (two-sided 90% confidence interval of 0.8 to 1.25 for the ratio of the means 
after intravenous administration/oral administration) to the AUC after oral administration.  
On the other hand, the Cmax did not satisfy the bioequivalence criteria for the ratio of the means 
after intravenous administration for 30, 60, and 90 minutes versus oral administration.  
Therefore, we developed a population pharmacokinetic model using the plasma concentration 
data in the Study 050, in order to simulate and estimate changes in the plasma concentration 
after switching to intravenous administration under steady-state conditions after multiple oral 
administration.  As a result, it was estimated that, under steady-state conditions, the Cmax after 
intravenous administration for 30 minutes and 60 minutes fell within the range of the criteria 
for bioequivalence to the Cmax after oral administration. 
In addition, based on a hearing from specialists in epilepsy regarding the time of administration 
of antiepileptic injection as an alternative therapy, it was suggested that an injection should be 
administered for no longer than 30 minutes in actual clinical settings. 
Based on the above findings, the time of study drug administration is set at 30 minutes. 
9.3  Selection of Study Population

containing 8 mg of perampanel (anhydrate) in a vial. 
Subjects will be switched from oral perampanel (8 to 12 mg/day; stable-dosage treatment 
during the Pretreatment Phase) on Day 1 to intravenous infusion of perampanel at a dose 
equivalent to the oral perampanel dose.  Subjects will receive 30-minute intravenous 
infusions of perampanel once a day in a supine position for 4 days under inpatient conditions 
(Days 1 through 4). 
The start time of intravenous infusions of perampanel from Day 1 to Day 4 will be designated 
as the same time as the administration time of oral perampanel on Day –1 (allowance window: 
±1 hour). 
As for the procedure for preparation of the intravenous infusion of perampanel, refer to the 
Instructions for Handling of Investigational Products provided by the sponsor.

9.5.1.3  Efficacy Assessments 
Efficacy will be assessed by seizure counts and types as recorded in the diary.  Diaries will be 
dispensed to all subjects and returned from all subjects at the visits designated in the Schedule 
of Procedures/Assessments (Table 2). 
The diary is to be completed by the subject, the designated subject’s caregiver, clinical nurses, 
or other site staff.  In the diary, all seizure counts and types will be recorded.  At each visit, 
the subject or the caregiver will be instructed by the investigator or the designated 
investigator’s staff as to how to complete the diary and reminded that they must bring the diary 
to their next scheduled visits including the Early Discontinuation Visit and the Follow-up Visit.  
Based on the diary, seizure counts and types will be recorded on the CRF. 
The investigator should review the diary for each subject at the visits designated in the 
Schedule of Procedures/Assessments (Table 2).  Subjects or caregivers must be counseled if 
diary compliance is not satisfactory. 
The retrieved diaries for each subject will be maintained appropriately at each investigational 
site throughout the required retention period (See Section 11.6 ). 
9.5.1.4  Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker 
Assessments 
9.5.1.4.1  PHARMACOKINETIC ASSESSMENTS 
Blood samples will be collected as specified in Table 2.  For procedures to collect, handle, 
and ship samples, see the separately specified written procedure.  The sampling date and time 
will be recorded in the CRF. 
Plasma concentration of perampanel will be measured by a validated liquid chromatography 
with tandem mass spectrometry (LC/MS/MS) assay. 
9.5.1.4.2  PHARMACODYNAMIC, PHARMACOGENOMIC, AND OTHER BIOMARKER, ASSESSMENTS 
Not applicable. 
9.5.1.5  Safety Assessments 
Safety assessments will consist of monitoring and recording all AEs and SAEs; laboratory 
evaluations for biochemistry, hematology, and urine values; periodic measurements of vital 
signs, weight, and 12-lead ECG; and the performance of physical examinations as detailed in 
Table 2. 
9.5.1.5.1  ADVERSE EVENTS 
An AE is any untoward medical occurrence in a clinical investigation subject administered an 
investigational product.  An AE does not necessarily have a causal relationship with the 

 
Eisai Co., Ltd. 
E2007-J081-240 
 
Date:  09 Oct 2018 
Confidential 
Page 29 of 53 
medicinal product.  For this study, the study drug is perampanel intravenous formulation. 
The criteria for identifying AEs in this study are: 
• 
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE) 
• 
Any new disease or exacerbation of an existing disease 
• 
Any deterioration in nonprotocol-required measurements of a laboratory value or other 
clinical test (eg, ECG or x-ray) that results in symptoms, a change in treatment, or 
discontinuation of the study drug 
• 
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
• 
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of the study drug, or 
withholding of the study drug, whether prescribed in the protocol or not. 
All AEs, regardless of relationship to the study drug or procedure, should be recorded in the 
CRF beginning from the time the subject signs the study ICF through the last visit and for 21 
days after the subject’s last dose of the study drug.  Serious AEs will be collected for 28 days 
after the last dose of the study drug.  In addition, the start date and time of an adverse event, 
and the end date and time of the adverse event will be recorded in the CRF. 
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute an 
AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality considered 
to constitute an AE should be reported on the CRF. 
All events associated with suicidal ideation/attempt, regardless of severity, must be recorded 
as an AE in the CRF. 
All AEs must be followed for 28 days after the subject’s last dose of the study drug, or until 
resolution, whichever comes first.  All SAEs and AEs of special interest (see Section 
9.5.1.5.3 ) must be followed to resolution or, if resolution is unlikely, to stabilization. 
Every effort must be made by the investigator to categorize each AE according to its severity 
and its relationship to the study treatment. 
Assessing Severity of Adverse Events 
AEs will be graded on a 3-point scale (mild, moderate, or severe) and reported in the detail 
indicated on the CRF.  The definitions are as follows: 

 
Eisai Co., Ltd. 
E2007-J081-240 
 
Date:  09 Oct 2018 
Confidential 
Page 30 of 53 
Mild 
Discomfort noticed, but no disruption of normal daily activities 
Moderate 
Discomfort sufficient to reduce or affect normal daily activities 
Severe 
 
Incapacitating, with inability to work or perform normal daily activities 
The criteria for assessing severity are different than those used for seriousness (see Section 
9.5.1.5.2 for the definition of an SAE). 
Assessing Relationship to Study Treatment 
Items to be considered when assessing the relationship of an AE to the study treatment are: 
• 
Temporal relationship of the onset of the event to the initiation of the study treatment 
• 
The course of the event, especially the effect of discontinuation of the study treatment, as 
applicable 
• 
Whether the event is known to be associated with the study treatment or with other 
similar treatments 
• 
The presence of risk factors in the study subject that are known to increase the occurrence 
of the event 
• 
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event 
Classification of Causality 
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question: 
Is there a reasonable possibility that the study drug caused the AE? 
Yes (related) 
A causal relationship between the study drug and the AE is a reasonable 
possibility. 
No (not related) A causal relationship between the study drug and the AE is not a reasonable 
possibility. 
9.5.1.5.2  SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS 
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
• 
Results in death 
• 
Is life-threatening (ie, the subject was at an immediate risk of death from the adverse 
event as it occurred; this does not include an event that, had it occurred in a more severe 
form or was allowed to continue, might have caused death) 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization 
• 
Results in persistent or significant disability/incapacity 

 
Eisai Co., Ltd. 
E2007-J081-240 
 
Date:  09 Oct 2018 
Confidential 
Page 31 of 53 
• 
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug) 
Other important medical events that may not be immediately life-threatening or result in death 
or hospitalization but, when based on appropriate medical judgment, may jeopardize the 
subject or may require intervention to prevent one of the outcomes in the definition of SAE 
listed above should also be considered SAEs.  Medical and scientific judgment should be 
exercised in deciding whether expedited reporting is appropriate in such situations.  
In addition to the above, other events associated with special situations include: pregnancy or 
exposure to the study drug through breastfeeding; AEs associated with study drug overdose, 
misuse, abuse, and medication errors (See Sections 9.5.4.2  and 9.5.4.3 ).  These events 
associated with special situations are to be captured using the SAE procedures but are to be 
considered as SAEs only if they meet one of the above criteria.  All AEs associated with 
special situations are to be reported on the CRF whether or not they meet the criteria for SAEs. 
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization. 
The following hospitalizations are not considered to be SAEs because there is no “adverse 
event” (ie, there is no untoward medical occurrence) associated with the hospitalization: 
• 
Hospitalizations for respite care 
• 
Planned hospitalizations required by the protocol 
• 
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed post study drug administration) 
• 
Hospitalization for administration of the study drug or insertion of access for 
administration of the study drug 
• 
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry 
9.5.1.5.3  STUDY-SPECIFIC ADVERSE EVENTS 
In a non-clinical toxicity study of sodium sulphobutylether-beta-cyclodextrin (hereinafter 
“SBECD”), which is one of the additives in this study drug, vacuolation was observed in 
tubular epithelial cells, suggesting that patients with impaired renal function have a risk of 
SBECD accumulation (Luke, et al., 2010).  In addition, there have been reports of anaphylaxis, 
possibly due to SBECD, with other formulations containing SBECD. 
In this study, based on the above findings, adverse events associated with renal dysfunction, 
and adverse events associated with anaphylaxis will be handled as “adverse events of special 
interest (AESIs)” and recorded in the CRF. 
For the procedures for reporting adverse events of special interest, see Section 9.5.4.3.2

1. Adverse Events Associated With Renal Dysfunction 
If an adverse event associated with renal dysfunction occurs, and does not resolve at the time 
point when the Follow-up Phase is completed, the investigator will monitor the subject for 14 
days from the follow-up visit, regardless of severity, and will continue following up the subject 
as needed until resolution of the event or, if resolution is unlikely, until stabilization of the 
symptom or sign.  During this period, the subject will be followed up continuously by renal 
function monitoring at unscheduled visits (eg, once weekly, or at a frequency deemed necessary 
by the investigator). 
2. Adverse Events Associated With Anaphylaxis 
In the event of an adverse event associated with anaphylaxis, the investigator will take the 
following responsive actions: 
• 
Take the first response, for example, by immediately referring the subject to an 
appropriate clinical department; 
• 
Make a decision regarding whether or not to continue administration of the study drug to 
the subject, based on advice from the physician in the above-mentioned department; 
• 
In the event of an adverse event associated with anaphylaxis while continuing intravenous 
administration of the study drug, discontinue the administration. In the event of any 
symptom or sign that is suspected of anaphylaxis while continuing intravenous 
administration of the study drug, careful judgment will be exercised in determining 
whether or not to continue the administration. 
The follow-up of anaphylaxis will be continued until resolution of the event or, if resolution is 
unlikely, until stabilization of the symptom or sign. 
9.5.1.5.4  LABORATORY MEASUREMENTS 
The clinical laboratory tests to be performed, including hematology, chemistry, and urinalysis, 
are summarized in Table 1.  The Schedule of Procedures/Assessments (Table 2) shows the 
visits and time points at which blood for clinical laboratory tests and urine for urinalysis will 
be collected in the study.  The sampling date will be recorded in the CRF.

9.5.3  Appropriateness of Measurements 
The safety assessments in this study are standard evaluations to ensure subject safety. 
The efficacy assessment (ie, seizure counts and types) comprises standard measurements 
commonly used in studies evaluating the effect of AEDs. 
9.5.4  Reporting of Serious Adverse Events, Pregnancy, and Events 
Associated With Special Situations 
9.5.4.1  Reporting of Serious Adverse Events 
All SERIOUS ADVERSE EVENTS, regardless of their relationship to study 
treatment, must be reported on a completed SAE form as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the event. 
Serious adverse events, regardless of causality assessment, must be collected through the 
last visit and for 28 days after the subject’s last dose of study drug.  All SAEs must be 
followed to resolution or, if resolution is unlikely, to stabilization. Any SAE judged by the 
investigator to be related to the study treatment or any protocol-required procedure should 
be reported to the sponsor regardless of the length of time that has passed since study 
completion. 
The detailed contact information for reporting of SAEs is provided in Attachment 1. 
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report. This includes the investigator’s assessment of causality. 
Any follow-up information received on SAEs should be forwarded within 1 business day 
of its receipt. If the follow-up information changes the investigator’s assessment of 
causality, this should also be noted on the follow-up SAE form. 
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested 
by the sponsor. 
9.5.4.2  Reporting of Pregnancy and Exposure to Study Drug Through 
Breastfeeding 
Any pregnancy in a female subject in which the estimated date of conception is either 
before the last visit or within 28 days of the last study treatment or any exposure to the 
study drug through breastfeeding during study treatment or within 28 days of the last study 
treatment must be reported. 
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, 
this should be reported regardless of the length of time that has passed since the exposure 
to study treatment.

A congenital anomaly, death during the perinatal period, an induced abortion, or a 
spontaneous abortion is considered to be an SAE and should be reported in the same time 
frame and in the same format as all other SAEs (see Section 9.5.4.1 ). 
Pregnancies or exposure to the study drug through breastfeeding must be reported by fax 
or email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy. The contact information for the reporting of pregnancies 
and exposure to the study drug through breastfeeding is provided in Attachment 1. The 
Pregnancy Report Form (Attachment 4) must be used for reporting. All pregnancies must 
be followed to outcome. The outcome of the pregnancy must be reported using the 
Pregnancy Outcome Report Form (Attachment 5) as soon as possible but no later than 1 
business day from the date the investigator becomes aware of the outcome. 
A subject who becomes pregnant must be withdrawn from the study. 
9.5.4.3  Reporting of Events Associated With Special Situations 
9.5.4.3.1  REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE, 
MISUSE, ABUSE, OR MEDICATION ERROR 
Adverse events associated with study drug overdose, misuse, abuse, and medication errors 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication errors are defined as follows: 
Overdose 
Accidental or intentional use of the study drug in an amount higher 
than the protocol-defined dose 
Misuse 
Intentional and inappropriate use of the study drug not in 
accordance with the protocol 
Abuse 
Sporadic or persistent intentional excessive use of the study drug 
accompanied by harmful physical or psychological effects 
Medication error 
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of 
site personnel 
All AEs associated with overdose, misuse, abuse, or medication errors should be captured 
on the Adverse Event CRF and also reported using the procedures detailed in Section 
9.5.4.1  even if the AEs do not meet serious criteria.  Abuse is always to be captured as 
an AE. If the AE associated with an overdose, misuse, abuse, or medication error does not 
meet serious criteria, it must still be reported using the SAE form and in an expedited 
manner but should be noted as nonserious on the SAE form and the Adverse Event CRF. 
9.5.4.3.2  REPORTING OF STUDY-SPECIFIC EVENTS 
In this study, adverse events associated with renal dysfunction and adverse events 
associated with anaphylaxis will be handled as “adverse events of special interest (AESIs)”

(see Section 9.5.1.5.3 ). 
If an adverse event of special interest associated with renal dysfunction, with an elevated 
creatinine level >3× the upper limit of normal (ULN), or an adverse event associated with 
anaphylaxis (regardless of severity) is observed, it will be reported according to the 
procedures specified in “Reporting of Serious Adverse Events” (Section 9.5.4.1 ) even if 
the AEs do not meet serious criteria.  If the event does not meet the definition of a SAE, 
it must still be reported using the SAE form and in an expedited manner but should be 
noted as nonserious on the SAE form and the Adverse Event CRF. 
9.5.4.4  Expedited Reporting 
The sponsor must inform the investigator, the head of the medical institution, and 
regulatory authorities of reportable events, in compliance with applicable regulatory 
requirements.  For this reason, it is imperative that the investigator provides complete 
SAE information in the manner described in Section 9.5.4.1 . 
9.5.4.5  Breaking the Blind 
Not applicable. 
9.5.4.6  Regulatory Reporting of Adverse Events 
Adverse events will be reported by the sponsor to the regulatory authorities in compliance 
with regulatory requirements and established guidance.  The format of these reports will 
be dictated by the regulatory requirements. 
9.5.5  Completion/Discontinuation of Subjects 
A subject may elect to discontinue the study at any time for any reason.  The investigator 
will promptly explain to the subject involved that the study will be discontinued for that 
subject and provide appropriate medical treatment and other necessary measures for the 
subject. 
All subjects who discontinue the study between the start of the first study treatment (Day 
1) and Day 4 are to complete the procedures/assessments at the Early Discontinuation Visit 
indicated in the Schedule of Procedures/Assessments (Table 2).  In addition, when the 
discontinuation has occurred before the start of the study treatment on Day 2, Day 3, or 
Day 4, the procedures/assessments that had been performed on that day of discontinuation 
can be deemed to be those at the Early Discontinuation Visit. 
Even if the procedures/assessments at the Early Discontinuation Visit have been conducted, 
the procedures/assessments at the Follow-up Visit designated in the Schedule of 
Procedures/Assessments (Table 2) will be performed 7 days (allowance window: +7 days) 
after the last dose of study drug, as far as possible.  In addition, between the Early 
Discontinuation Visit and the Follow-up Visit, the study treatment will be switched back 
to the original dose of oral perampanel used in the Pretreatment Phase, and a stable dosage 
of another AED(s) as an adjunctive therapy as well as recording of seizures (recording by

the subjects’ caregiver is also acceptable) will be continued, as far as possible.  The results 
of these procedures/assessments and the relevant drug information regarding oral 
perampanel and the other AED(s) will be recorded in the CRF. 
If by any chance the procedures/assessments at the Early Discontinuation Visit cannot be 
conducted before the Follow-up Visit which is to occur 7 days (allowance window: +7 
days) after the last dose of study drug, the procedures/assessments at the Follow-up Visit 
can be omitted. 
A subject who has ceased to return for visits will be followed up by mail, phone, or other 
means to gather information such as the reason for failure to return, the status of treatment 
compliance, the presence or absence of AEs, and clinical courses of signs and symptoms. 
Subjects who discontinue early from the study will be discontinued for 1 primary reason.  
In addition to the primary reason, the subject may indicate 1 or more secondary reason(s) 
for discontinuation.  Study disposition information will be collected on the Subject 
Disposition CRF. 
If subjects cannot continue the study drug for any reason(s), they must discontinue the 
study.  In addition, a subject who becomes pregnant must be withdrawn from the study. 
9.5.6  Abuse or Diversion of Study Drug 
Not applicable. 
9.5.7  Confirmation of Medical Care by Another Physician 
The investigator or the designated investigator’s staff will instruct the subjects and the 
subjects’ legally acceptable representatives (if applicable) to inform site personnel when 
the subjects are planning to receive medical care from another physician.  At each visit, 
the investigator or the designated investigator’s staff will ask the subject and the subject’s 
legally acceptable representative (if applicable) whether the subject has received medical 
care by another physician since the last visit or is planning to do so in the future.  When 
the subject is going to receive medical care by another physician, the investigator, with the 
consent(s) of the subject and the subject’s legally acceptable representative (if applicable), 
will inform the other physician that the subject is participating in the clinical study. 
9.6  Data Quality Assurance 
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines. 
9.6.1  Data Collection 
Data required by the protocol will be collected on the CRFs and entered into a validated 
data management system that is compliant with all regulatory requirements.  As defined 
by J-GCP guidelines, the CRF is a printed, optical, or electronic document designed to

analytical plan will be provided in the statistical analysis plan (SAP), which will be 
finalized before database lock. 
9.7.1.1  Study Endpoints 
The safety endpoints are AEs, clinical laboratory tests (biochemistry, hematology, and 
urinalysis), vital signs, weight, and 12-lead ECG. 
The efficacy endpoint is the seizure frequency per day in each of the 3 phases (Pretreatment 
Phase, Treatment Phase, and Follow-up Phase).  Seizure frequency per day will be 
derived from the information recorded in the subject diaries. 
The pharmacokinetic endpoint is the plasma concentration of perampanel. 
All observed data will be reported with no adjustments for missing data.

and 
Other 
Biomarker Analyses 
9.7.1.7.1  PHARMACOKINETIC ANALYSES 
The PK analyses will be performed on the Pharmacokinetic Analysis Set using the plasma 
concentrations of perampanel.  Summary statistics for the plasma concentrations will be 
obtained by sampling time point and dose.  The plasma concentrations of perampanel 
before and after switching from oral tablet to intravenous infusion will be plotted.  A 
similar analysis may be conducted using dose-normalized plasma concentration data. 
9.7.1.7.2  PHARMACODYNAMIC, PHARMACOGENOMIC, AND OTHER BIOMARKER ANALYSES 
Not applicable. 
9.7.1.8  Safety Analyses 
The safety analyses will be performed on the Safety Analysis Set. 
Safety data will be summarized using descriptive statistics (eg, n, mean, SD, median, 
minimum, and maximum for continuous variables; n [%] for categorical variables).  
Safety variables include AEs, clinical laboratory parameters (biochemistry, hematology, 
and urinalysis), vital signs, weight, and 12-lead ECG results. 
9.7.1.8.1  EXTENT OF EXPOSURE 
The extent of exposure to the study drug will be summarized using descriptive statistics. 
9.7.1.8.2  ADVERSE EVENTS 
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA). Adverse events will be coded to the MedDRA (Version 21.0 or higher) lowest 
level term (LLT) closest to the verbatim term. The linked MedDRA preferred term (PT) 
and primary system organ class (SOC) are also captured in the database. 
A treatment-emergent adverse event (TEAE) is defined as an AE that emerges on or after 
the start of the study treatment, having been absent at pretreatment or 
• 
Reemerges on or after the start of the study treatment, having been present at 
pretreatment but stopped before the start of the study treatment, or 
• 
Worsens in severity on or after the start of the study treatment relative to the 
pretreatment state, when the AE is continuous. 
All AEs, treatment-emergent or otherwise, will be presented in the subject data listings. 
The incidences of TEAEs will be reported as the number (percentage) of subjects with 
TEAEs by SOC and PT.  A subject will be counted only once within an SOC and PT, 

 
Eisai Co., Ltd.

Page 44 of 53 
 
even if the subject experienced more than 1 TEAE within a specific SOC and PT.  The 
number (percentage) of subjects with TEAEs will also be summarized by maximum 
severity (mild, moderate, or severe). 
The number (percentage) of subjects with treatment-related TEAEs will be summarized 
by SOC and PT.  Treatment-related TEAEs include those events considered by the 
investigator to be related to the study treatment.  The number (percentage) of subjects 
with treatment-related TEAEs will also be summarized by maximum severity (mild, 
moderate, or severe). 
The number (percentage) of subjects with AEs by SOC and PT will be summarized by 
Phase (Pretreatment Phase, Treatment Phase, and Follow-up Phase) of onset. 
Subject data listings of all AEs leading to death, all SAEs, and all AEs leading to 
discontinuation from the study will be provided. 
9.7.1.8.3  LABORATORY VALUES 
Laboratory results will be summarized using Système International (SI) units, as 
appropriate.  For all quantitative parameters, the actual value at each visit and the change 
from baseline to each postbaseline visit will be summarized using descriptive statistics.  
Qualitative parameters will be summarized using frequencies (number and percentage of 
subjects), and changes from baseline to each postbaseline visit will be reported using shift 
tables.  Percentages will be based on the number of subjects with both nonmissing 
baseline and relevant postbaseline results. 
Laboratory test results will be assigned a low/normal/high (LNH) classification according 
to whether the value was below (L), within (N), or above (H) the laboratory parameter’s 
reference range.  Within-treatment comparisons for each laboratory parameter will be 
based on shift tables that compare the baseline LNH classification to the LNH 
classification at each postbaseline visit. 
Appendix 1 (Sponsor’s Grading for Laboratory Values) presents the criteria that will be 
used to identify subjects with treatment-emergent markedly abnormal laboratory values 
(TEMAVs).  Except for phosphate, a TEMAV is defined as a postbaseline value with an 
increase from baseline to a grade of 2 or higher.  For phosphate, a TEMAV is defined as 
a postbaseline value with an increase from baseline to a grade of 3 or higher.  The 
definition of TEMAV will be detailed in the SAP.  When displaying the incidence of 
TEMAVs, each subject may be counted once in the laboratory parameter high and in the 
laboratory parameter low categories, as applicable. 
9.7.1.8.4  VITAL SIGNS AND WEIGHT 
Descriptive statistics for vital sign parameters (ie, systolic and diastolic blood pressure, 
pulse, respiratory rate, temperature) and weight; and changes from baseline will be 
presented by visit.

9.7.1.8.6  OTHER SAFETY ANALYSES 
Not applicable. 
9.7.2  Determination of Sample Size 
This is an uncontrolled, open-label study for the safety evaluation of intravenous infusion 
of perampanel and the sample size (20 subjects) is not based on statistical power 
considerations, but rather on feasibility.  It is considered that a sufficient number of 
subjects will be obtained for the safety evaluation of intravenous infusion of perampanel 
if the sample size is 20. 
9.7.3  Interim Analysis 
No interim analysis is planned for this study. 
9.7.4  Other Statistical/Analytical Issues 
Not applicable. 
9.7.5  Procedure for Revising the Statistical Analysis Plan 
If the SAP needs to be revised after the study starts, the sponsor will determine how the 
revision impacts the study and how the revision should be implemented.  The details of 
the revision will be documented and described in the clinical study report.

11. PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES) 
11.1  Changes to the Protocol 
Any change to the protocol requires a written protocol amendment or administrative 
change that must be approved by the sponsor before implementation. 
Amendments specifically affecting the safety of the subjects, the scope of the investigation, 
or the scientific quality of the study require additional approval by the applicable IRBs.  
These requirements should in no way prevent any immediate action from being taken by 
the investigator, or by the sponsor, in the interest of preserving the safety of all subjects 
included in the study.  If the investigator determines that an immediate change to or 
deviation from the protocol is necessary for safety reasons to eliminate an immediate 
hazard to the subjects, the sponsor and the IRB for the site must be notified immediately.  
The sponsor must notify the health or regulatory authority as required per regulations. 
Protocol amendments that affect only administrative aspects of the study may not require 
submission to the IRB.  In these cases, the sponsor may be required to send a letter to the 
head of the medical institution detailing such changes. 
11.2  Adherence to the Protocol 
The investigator will conduct the study in strict accordance with the protocol. 
11.3  Monitoring Procedures 
The sponsor’s CRA will maintain contact with the investigator and designated staff by 
telephone, letter, or email between study visits.  Monitoring visits to the site will be 
conducted by the assigned CRA as described in the monitoring plan.  The head of the 
medical institution will allow the CRA to inspect the clinical, laboratory, and pharmacy 
facilities to assure compliance with J-GCP and other regulatory requirements.  The CRFs 
and subject’s corresponding original medical records (source documents) are to be fully 
available for review by the sponsor’s representatives at regular intervals.  These reviews 
verify adherence to the study protocol and data accuracy in accordance with J-GCP.  All 
records at the site are subject to inspection by the auditing agency and to IRB review. 
In accordance with J-GCP, source documents include, but are not limited to the following: 
• 
Clinic, office, or hospital charts 
• 
Copies or transcribed health care provider notes which have been certified for 
accuracy after production 
• 
Recorded data from automated instruments 
• 
Medical history questionnaires completed by subjects 
• 
Records of telephone contacts 
• 
Diaries or evaluation checklists

• 
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel 
• 
Laboratory results and other laboratory test outputs 
• 
Correspondence regarding a study subject’s treatment between physicians or 
memoranda sent to the IRB 
11.4  Recording of Data 
A CRF is required and must be completed for each subject who has consented/assented to 
participate in the study by qualified and authorized personnel.  All data on the CRF must 
reflect the corresponding source document, except when a section of the CRF is itself used 
as the source document.  Any correction to entries made on the CRF must be documented 
in a valid audit trail where the correction is dated, the individual making the correct is 
identified, the reason for the change is stated, and the original data are not obscured.  Only 
data required by the protocol for the purposes of the study should be collected. 
The investigator must sign each CRF.  The investigator will report the CRFs to the 
sponsor and retain copies of the CRFs. 
11.5  Identification of Source Data 
All data to be recorded on the CRF must reflect the corresponding source documents. 
The data collected directly on the CRF are considered source data.  For instance, the 
following data recorded directly on the CRF are to be considered source data: 
• 
Status of the study treatment (eg, reasons for discontinuation of the study treatment) 
• 
Indication for prior or concomitant therapy 
• 
Information on withdrawal from the study, for example, in the case of being lost to 
follow-up 
• 
Sampling date and time for drug concentrations and clinical laboratory tests 
• 
Information on AEs (eg, severity, relationship to the study drug, and outcome) 
11.6  Retention of Records 
The circumstances of completion or termination of the study notwithstanding, the head of 
the medical institution (or the designated representative) is responsible for retaining all 
study documents, including but not limited to the protocol, copies of the CRFs, the 
Investigator's Brochure, and regulatory agency registration documents (eg, ICFs, and IRB 
correspondence).  The site should retain study documents until the approval date of a 
marketing application, at least 3 years have elapsed since the formal discontinuation of 
clinical development of the investigational product, at least 3 years have elapsed since 
receipt of a notice that the registration application should not include the results of the 
study, or at least 3 years have elapsed since the formal discontinuation or termination of 
the study, whichever comes last. 
It is requested that at the completion of the required retention period, the site contact the

sponsor, allowing the sponsor the option of permanently retaining the study records. 
11.7  Auditing Procedures and Inspection 
In addition to the routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of J-GCP and other applicable regulations.  
In addition, there is the possibility that a government regulatory authority will conduct an 
inspection. 
11.8  Handling of Study Drug 
All study drug will be supplied to the designated pharmacist or the designee by the sponsor.  
Drug supplies must be kept in an appropriate secure area (eg, locked cabinet) and stored 
according to the conditions specified on the drug labels.  The designated pharmacist or 
the designee must maintain an accurate record of the shipment and dispensing of the study 
drug in a drug accountability ledger.  An accurate record of the date and amount of study 
drug dispensed to each subject must be available for inspection at any time.  The CRA 
will visit the site and review these documents along with all other study conduct documents 
at appropriate intervals once the study drug has been received by the site. 
All drug supplies are to be used only for this study and not for any other purpose.  The 
designated pharmacist or the designee must not destroy any drug labels or any partly used 
or unused drug supply before approval to do so by the sponsor.  At the conclusion of the 
study and as appropriate during the study, the designated pharmacist or the designee will 
return all unused study drug to the sponsor. 
11.9  Publication of Results 
All manuscripts, abstracts, or other modes of presentation arising from the results of the 
study must be reviewed and approved in writing by the sponsor in advance of submission 
pursuant to the terms and conditions set forth in the executed Clinical Trial Agreement 
between the head of the medical institution and the sponsor.  The review is aimed at 
protecting the sponsor's proprietary information existing either at the date of the 
commencement of the study or generated during the study. 
The detailed obligations regarding the publication of any data, material results, or other 
information, generated or created in relation to the study shall be set out in the Clinical 
Trial Agreement executed between the head of the medical institution and the sponsor, as 
appropriate. 
11.10  Disclosure and Confidentiality 
The contents of this protocol and any amendments and results obtained during the study 
should be kept confidential by the investigator, the investigator’s staff, and the IRB and 
will not be disclosed in whole or in part to others, or used for any purpose other than 
reviewing or performing the study, without the written consent of the sponsor.  No data

collected as part of this study will be used in any written work, including publications, 
without the written consent of the sponsor.  These obligations of confidentiality and non-
use shall in no way diminish such obligations as set forth in the Clinical Trial Agreement 
executed between the head of the medical institution and the sponsor. 
All persons assisting in the performance of this study must be bound by the obligations of 
confidentiality and non-use set forth in the Clinical Trial Agreement executed between the 
head of the medical institution and the sponsor. 
11.11  Discontinuation of Study 
The sponsor reserves the right to discontinue the study for medical reasons or any other 
reason at any time.  If a study is prematurely terminated or suspended, the sponsor will 
promptly inform the investigators/head of the medical institution and the regulatory 
authorities of the termination or suspension and the reason(s) for the termination or 
suspension.  The IRB will also be informed promptly and provided the reason(s) for the 
termination or suspension by the sponsor or by the investigator/head of the medical 
institution, as specified by the applicable regulatory requirement(s). 
The investigator reserves the right to discontinue the study should his/her judgment so 
dictate.  If the investigator terminates or suspends a study without the prior agreement of 
the sponsor, the investigator should inform the head of the medical institution where 
applicable, and the investigator/head of the medical institution should promptly inform the 
sponsor and the IRB and provide the sponsor and the IRB with a detailed written 
explanation of the termination or suspension.  Study records must be retained as noted 
above. 
11.12  Subject Insurance and Indemnity 
The sponsor will provide insurance for any subjects participating in the study in accordance

List of Changes of Protocol (from Version 1 to Version 2) 
Title: A multicenter, uncontrolled, open-label study to evaluate the safety and tolerability of intravenous perampanel as substitute for 
oral tablet in subjects with partial onset seizures (including secondarily generalized seizures) or primary generalized tonic-
clonic seizures 
 
Protocol Sections 
Before (Version 1 dated 07 Sep 2018) 
After (Version 2 dated 09 Oct 2018) 
Rationale 
9.5.1.5.1 
ADVERSE EVENTS 
Abnormal laboratory values should not be listed as 
separate AEs if they are considered to be part of 
the clinical syndrome that is being reported as an 
AE.  It is the responsibility of the investigator to 
review all laboratory findings in all subjects and 
determine if they constitute an AE.  Medical and 
scientific judgment should be exercised in 
deciding whether an isolated laboratory 
abnormality should be classified as an AE.  Any 
laboratory abnormality considered to constitute an 
AE should be reported on the CRF. 
All AEs must be followed for 28 days after the 
subject’s last dose of the study drug, or until 
resolution, whichever comes first.  All SAEs and 
AEs of special interest (see Section 9.5.1.5.3 ) 
must be followed to resolution or, if resolution is 
unlikely, to stabilization.

scientific judgment should be exercised in 
deciding whether an isolated laboratory 
abnormality should be classified as an AE.  Any 
laboratory abnormality considered to constitute an 
AE should be reported on the CRF. 
All events associated with suicidal 
ideation/attempt, regardless of severity, must be 
recorded as an AE in the CRF. 
All AEs must be followed for 28 days after the 
subject’s last dose of the study drug, or until 
resolution, whichever comes first.  All SAEs and 
AEs of special interest (see Section 9.5.1.5.3 ) 
must be followed to resolution or, if resolution is 
unlikely, to stabilization. 
Added the handling of 
events associated with 
suicidal ideation/attempt 
based on the sponsor’s 
response to PMDA’s 
inquiry issued after the first 
Clinical Trial Notification 
(CTN) for perampanel 
intravenous formulation.
