Study Product, Dose, Route, Regimen 
PER is a noncompetitive AMPA glutamate 
receptor antagonist. The two phases of the 
treatment portion of this study include a titration 
phase and a stable dosing phase. This study will 
have two treatment arms consisting of PER and 
alternative ASD arm. The PER arm will begin a 
titration phase with 2mg PER PO q.d. (may be 
split to b.i.d.) for one week and increase by 
2mg/week until reaching an initial dose of 4mg 
PO q.d. (q.d. or b.i.d. dosing) is reached. Flexible 
dosing of PER above 4mg to a maximum of 8 mg 
daily will be compared to use of alternative ASDs 
and be guided by best clinical practices with 
dosing and indication within U.S. FDA 
guidelines.  
 
Duration of Administration 
Participants will be assigned to receive open label 
PER or an alternate ASD for at least 12 week and 
up to 40weeks for the remainder of the study. This 
includes 2-4 weeks of titration and up to 40 weeks 
of stable dosing. Reduction by 2 mg will be 
allowed in cases of efficacy if doses greater than 4 
mg daily result in non-idiosyncratic side-effects.  
Reference therapy 
All comparisons will use standard ASDs as the 
reference therapy using an intent to treat study 
design for patients initiating or tapering off PER 
therapy. 
Statistical Methodology 
Statistical analysis will include Student T-test, 
Chi-square for categorical differences. An interim 
analysis will be performed when half of the 
targeted subjects are enrolled. 
 
 
1 Introduction 
This document is a clinical research protocol for a human research study. This study will be carried out in 
accordance with the applicable United States government regulations and Mayo Clinic research policies 
and procedures.  
1.1 
Background 
Does the novelty of Perampanels unique mechanism of action demonstrate anti-seizure efficacy, tumor-
cidal activity, and impact progressive impairment in neurocognitive function in patients with high-grade 
glioma? The major reasons why this study should be conducted include:  
1. Seizures commonly occur in 40% to 70% of patients with a primary brain tumor/glioma.3 
2. PER is FDA approved for adults with focal seizures.7, 11

CONFIDENTIAL 
3. PER has novel and unique mechanisms of action that include a primary effect on excitatory 
amino acids/AMPA.7,8,11 
4. Glutamate-induced excitotoxicity and disruption of intracellular communication hold a key role 
in the progression of disease in patients with glioblastoma (altered cysteine-glutamate transport).5, 
10, 11 
5. Glutamate induced over-activity is also suspected to influence high-grade glioma growth.5, 13 
6. Studies show that isocitrate dehydrogenase 1 (IDH1) mutant gliomas are more likely to cause 
seizures than IDH1 wild-type gliomas. The IDH1 mutation has been associated with 
tumorigenesis and has implications relative to differential treatment for primary brain cancer and 
prognosis.5 
 
Because of shared pathways, current anti-seizure drugs (ASDs) may affect treatment of patients with 
brain tumor, and various antitumor therapies are valuable for seizure management. Mechanisms involving 
cysteine-glutamine transporters, for example, regulate glutamate release and return through cellular 
exchange. One explanation for the close link between seizures and glioma evolution are elevated 
extracellular glutamate levels in the peri-glial and -neuronal space with ensuing over-activity of 
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and N-methyl-d-aspartate (NMDA) 
receptors in both conditions. Recent studies point to the role of glutamate in excitotoxic damage resulting 
in seizures as well as maintenance and invasion of malignant glioma.  Blockade of this system could lead 
to pharmaceutical development that could affect the excitotoxicity of both high-grade glioma and brain-
tumor related epilepsy. Human trials of PER demonstrate safety and efficacy as an adjunctive therapy for 
adult patients with epilepsy. Limited information is available to demonstrate effectiveness in 
subpopulations associated with excessive glutamatergic stimulation such as brain tumor. PER, a FDA 
approved AMPA antagonist cleared for clinical use, may have immediate impact in 80,000 patients with 
brain tumors, and 3.4 million Americans with epilepsy (commonly co-morbid conditions). Anecdotal 
benefit has been reported in epilepsy patients with primary brain tumor and low dose PER (Vecht et al., 
2017). Cognitive decline frequently complicates treatment of patients with high-grade glioma and also in 
patients with epilepsy impairing overall QoL. 
 
1.2 
Investigational Agent 
Participants will be assigned to receive open label PER or an alternate ASD for 40 weeks. The route of drug 
delivery will be orally administered (PO). 
1.3 
Preclinical Data 
Because of shared pathways, current anti-seizure drugs (ASDs) may affect treatment of patients with 
brain tumor, and various antitumor therapies are valuable for seizure management. Mechanisms involving 
cysteine-glutamine transporters regulate glutamate release and return through cellular exchange. Blockade 
of this system could lead to pharmaceutical development that could affect the excitotoxicity of both high-
grade glioma and other brain-tumor related epilepsy syndromes. Limited information is available to 
demonstrate effectiveness in subpopulations associated with excessive glutamatergic stimulation such as 
brain tumor.  
1.4 
Clinical Data to Date 
Human trials of PER have demonstrated its efficacy as an adjunctive therapy for adult patients with 
epilepsy. Furthermore, Anecdotal improvements in both seizure frequency and tumor progression have 
been reported in epilepsy patients with primary brain tumors on low-dose PER (Vecht et al., 2017).

CONFIDENTIAL 
1.5 
Dose Rationale  
We will follow FDA recommendations for dosing of PER14. As such, patients will begin on PER 2 mg PO 
and increase in weekly intervals of 2 mg/week until reaching minimum dose of at least 4 mg/day and a 
maximum of 8 mg/day per patient. Alternative ASDs will be instituted according to best clinical practice 
and without excessive dosing beyond standard doses approved by the U.S. Food and Drug 
Administration. Participants will be assigned to receive open label PER or an alternate ASD for 40 weeks. 
The frequency of oral delivery of PER will be every 24 hours but no more frequently than every 12 hours. 
The route of drug delivery will be orally administered (PO). The otherASD will be chosen and be 
administered according to prior exposure to ASDs and according to best clinical practice. 
1.6 
Risks and Benefits 
Side effects associated with PER include anxiety, dizziness, headache, irritability, problems with 
coordination and balance, sleepiness, nausea, and weight gain. Serious side effects observed in clinical trials 
for patients taking PER include psychiatric and behavioral problems consisting of aggression, hostility, 
anger, and suicidal thoughts or behavior. In response to these psychiatric and behavioral risks that have 
been associated with patients beginning PER or taking increased doses of the drug, individuals who disclose 
history of prior felony conviction or who have violent behavior present in historical review will be excluded 
from the study. Additionally, any patients with clinically significant suicide risk (e.g., suicide attempt in 
the past 5 years or active suicidality as judged by the clinician) will be excluded from the study. Patients 
will be screened and monitored for changes in psychological status and behavior using the Neurological 
Disorders Depression Inventory for Epilepsy (NDDI-E), PHQ-9, Columbia-Suicide Severity Rating Scale 
(C-SSRS), and Quality of Life in Epilepsy Inventory (QOLIE-31) throughout the study. Patients’ status 
will be closely monitored by the physicians throughout the study with the low probability of developing 
these side effects outweighed by the benefits PER can provide to patients.  
 
2 Study Objectives 
Primary Objective 
Demonstrate the efficacy and safety of PER on seizure frequency in adult patients with biopsy-proven 
high-grade glioma and focal Epilepsy compared with alternate ASDs. 
 
 
Secondary Objective 
To assess the change in neurocognitive function and brain MRI progression over the course of PER 
treatment with a daily dose of 4 mg (up to -8mg) in patients with biopsy-proven high-grade glioma and 
focal epilepsy compared with alternate ASDs. 
To identify a biomarker-specific response to seizure-reduction in patients treated with PER in patients 
with a biopsy-proven high-grade glioma (i.e., IDH-mutant vs wildtype).

awareness, and focal to bilateral tonic-clonic seizures), with at least 1 seizure/month during a 
retrospective 2-month baseline, relative to the screening visit.  
All patients included in the study will follow STUPP protocol (radiotherapy plus concomitant and 
adjuvant Temozolomide) for treatment of high-grade glioma in addition to best medical practice of 
comorbidities, as is standard-of-care15.

3.3 
Duration of Participation 
12 months 
3.4 
Primary Endpoints 
 
A. The number of patients with a high-grade glioma who achieve a > 50% reduction in focal 
seizures with PER 4 mg daily after failing 1 or more ASDs at 3 and 6 months.   
1. The overall survival of patients with high-grade glioma treated with PER at 3 months. 
2. Decline in neuropsychological function at 6 months. 
All comparisons will use intent to treat model for patients initiated or exiting PER therapy. In event of 
patients not surviving till 12 months, most recent data prior to death will be used for correlation.  
 
3.5 
Identification of Source Data 
Electronic medical records will be maintained via a RedCAP database for consecutive and prospective 
collection of data.  
 
Efficacy measures used in the study include: clinical assessments will include serial brain MRI, EEG, 
anti-seizure drug levels and subject self-assessment at clinical follow-up; Neurological Disorders 
Depression Inventory for Epilepsy (NDDI-E), assessment for screening of depression PHQ-9;Montreal 
Outcome Cognitive Assessment (MOCA);  Clinical Global Impression of Change (CGIC) score; 
Columbia –Suicide Severity Rating Scale. Seizure calendars performed at 2 months prior to initiation of 
therapy or adequate reliable historical baseline, and then monthly during study; and QOLIE-31, (see 
schedule of events for frequency of assessment). 
 
Anatomic brain MRI with perfusion scanning/gadolinium will be obtained at 3 months and then every 3 
months, to examine the correlated progression of brain tumor, or the absence of tumor. Laboratory studies 
will be employed before and after PER initiation. EEG will be obtained at baseline and at 3 months and 
12 months to identify changes in background activity (e.g. diffuse slowing) and epileptiform discharges to 
correlate with focal seizure presence vs absence. Neuropsychological batteries will determine the 
presence or absence of significant anxiety, depression or cognitive changes over time and quality of life 
inventory will be obtained at the beginning, intermediate and end of the trial. 
 
The following source data will be directly recorded on the Case Report Form (CRF):  
● A comprehensive History and Physical examination and Neurological examination will occur at 
the initial screening/baseline. 
● Clinical visitation will occur at screening/baseline, 3, 6, and 12 months.

Survey questionnaires will be obtained at baseline, 3, 6, 9, and 12 months. The following source 
data will not be directly collected in the Case Report Form (CRF), but will be captured in 
supportive documentation (study source documents, EMR): 
● Laboratory studies will be employed at baseline and at each clinical visit after PER initiation.   
● Brain tumor tissue will be assessed for the usual molecular markers (i.e., IDH-mutant vs 
wildtype, MGMT methylation, ARX). 
● 12-lead ECG will be obtained at baseline and as clinically indicated 
● Anatomic brain MRI with and without gadolinium will be obtained at baseline and follow-up 
brain MRI at 3 months and 6 months during PER use. 
● EEG will be obtained at baseline and at 3 months and 12 months to identify changes in background 
activity (e.g. diffuse slowing) and epileptiform discharges to correlate with focal seizure presence 
vs absence.  
● Neuropsychological batteries will be obtained at baseline, 3 months, and 6 months to determine 
the presence or absence of significant neurocognitive decline.

The Principal and Co-Investigator as well as Study Coordinator are responsible for individual safety 
monitoring. Stopping or interruption of the study may be necessary if a significant number of study 
participants develop unexpected clinical flaring or significant worsening that appears temporally 
linked with PER administration to be used for the indication outlined in this protocol. 
 
The Principal Investigator and/or Investigator will review all adverse event reports to determine if 
specific reports need to be made to the IRB and FDA. For this study, all SAEs or possible UPIRTSOs 
will be reported to the IRB. 
4.4.2 Data Collection and Follow-up for Withdrawn Subjects 
All study data will be stored in the password protected REDCAP database. Access to the REDCAP 
database will be limited to the Principal Investigator, Investigators and Statistician. Paper documents, 
including patient seizure logs/diaries and case report forms, will be kept in a locked cabinet with 
access available only to the Investigators and Study Coordinator. 
 
The sponsor-investigator will maintain records and essential documents related to the conduct of the 
study for a period of 2 years after completion of the study.  These will include subject case histories 
and regulatory documents. All study data will be collected and managed using REDCap electronic 
data capture tools hosted at the Mayo Clinic. REDCap (Research Electronic Data Capture) is a secure, 
web-based application designed to support data capture for research studies, providing 1) an intuitive 
interface for validated data entry; 2) audit trails for tracking data manipulation and export procedures; 
3) automated export procedures for seamless data downloads to common statistical packages; and 4) 
procedures for importing data from external sources.

5 Study Drug  
5.1 
Description 
PER is a noncompetitive AMPA glutamate receptor antagonist.  
5.2 
Treatment Regimen 
Patients will begin on PER 2 mg PO and increase in weekly intervals of 2 mg/week until reaching 
minimum dose of at least 4 mg/day and a maximum of 8 mg/day per patient. Alternative ASDs will 
be instituted according to best clinical practice and without excessive dosing beyond standard doses 
approved by the U.S. Food and Drug Administration. Participants will be assigned to receive open 
label PER or an alternate ASD for 40 weeks. The frequency of oral delivery of PER will be every 
24 hours but no more frequently than every 12 hours. The route of drug delivery will be orally 
administered (PO). The other ASDs will be chosen and be administered according to prior 
exposure to ASDs and according to best clinical practice. 
5.3 
Method for Assigning Subjects to Treatment Groups 
Participants will be assigned to receive: 
Group A: open label arm of adjunctive PER (study drug) for patients with seizures treated with at 
least 1 ASD administered in escalating divided doses of 2 mg/week to 4 mg daily with flexible 
dosing to 8 mg/day by 4 weeks. Subjects must undergo forced titration of 2 mg/week and be able to 
tolerate 4 mg to continue in the study. Concomitant ASD will be utilized according to best clinical 
practice.  
or  
Group B: continued open label treatment for patients with seizures treated with at least 1 ASD, as 
per best medical practice, without the use of PER. 
5.4 
Preparation and Administration of Study Drug 
PER (to be used for the indication outlined in this protocol) will be shipped by Eisai to the Mayo 
Clinic research pharmacy in Florida. Upon receipt, an inventory will be performed, and a drug 
receipt log filled out by the person accepting the shipment. Designated study staff will count 
and verify that the shipment contains all the items noted on the shipping invoice. Any 
discrepancies, damaged or unusable drug in any given shipment will be documented in the 
study files. The Investigators must be notified immediately of any discrepancies, damages 
or unusable products that are received. 
5.5 
Subject Compliance Monitoring 
Anti-seizure drug levels will be evaluated at clinical follow-up (see study schema for frequency of 
assessment). 
5.6 
Prior and Concomitant Therapy 
Concomitant therapy will allow 0-3 concomitant ASDs. No specific drugs will be disallowed; 
concomitant ASDs and non-ASDs (e.g. narcotics, benzodiazepines, and barbiturates) will serve as 
exclusionary therapies when deemed clinically relevant according to best clinical practice. 
5.7 
Packaging 
Study drug will be packaged according to the manufacturer’s approval for use by the U.S. FDA.

The contents of the package will include study drug and associated approved labelling. 
5.8 
Masking/Blinding of Study  
This is an open-label study.  
5.9 
Receiving, Storage, Dispensing and Return 
Study drug will be received by the principal investigator and stored in a secured location. Unused 
medication will be returned to the study institution and returned to Eisai Pharmaceuticals. 
5.9.1 Receipt of Drug Supplies 
Perampanel (to be used for the indication outlined in this protocol) will be shipped by Eisai to the 
Mayo Clinic research pharmacy in Florida. Upon receipt, an inventory will be performed and a 
drug receipt log filled out by the person accepting the shipment. Designated study staff will count 
and verify that the shipment contains all the items noted on the shipping invoice. Any 
discrepancies, damaged or unusable drug in any given shipment will be documented in the study 
files. The investigators must be notified immediately of any discrepancies, damages or unusable 
products that are received. 
5.9.2 Storage 
Perampanel will be stored at Mayo Clinic research pharmacy in Florida. Medication will be 
stored at room temperature (between 68 and 77º F) with limited exposure to heat, moisture, and 
light.  
5.9.3 Dispensing of Study Drug 
Regular study drug reconciliation will be performed to document drug assigned, drug 
dispensed, drug returns, and drug remaining.  This reconciliation will be logged on the 
drug reconciliation form and signed and dated by the study team. 
5.9.4 Return or Destruction of Study Drug 
At the completion of the study, there will be a final reconciliation of drug shipped, drug dispensed, 
drug returns, and drug remaining.  This reconciliation will be logged on the drug reconciliation form, 
signed and dated.  Any discrepancies noted will be documented and investigated, prior to return or 
destruction of unused study drug.  Drug destroyed on site will be documented in the study files.

7 Statistical Plan 
7.1 
Sample Size Determination 
 
A sample size of 20 patients is targeted as part of a pilot study to determine feasibility for a larger 
prospective multi-center trial. The sample size is targeted to achieve adequate enrollment and determine 
the likelihood of supporting a larger study.  
This study is not designed to be powered to determine significance for statistical significance of 
effectiveness.  
7.2 
Statistical Methods 
 
Descriptive Statistics 
 
Statistical analysis will include Student T-test, Chi-square for categorical differences. An interim analysis 
will be performed when half of subjects are enrolled. 
 
Handling of Missing Data 
 
 
Study data will be collected and managed using REDCap electronic data capture tools hosted at 
Mayo Clinic. All data requested on the Case Report Form (CRF) will be recorded for each 
participant. A standardized CRF will be generated by REDCap. For any data query, the Principal 
Investigator and Investigators will meet to clarify the data queried and make corrections based on 
consensus. Once the study is completed, the Principal Investigator will randomly select 3 
participants and compare the data documented for each on the CRF with what is entered into the 
REDCap database. If there is any discrepancy, the Principal Investigator and/or Investigators will 
cross-reference all 20 patients to ensure accuracy. 
 
Primary Hypothesis: We hypothesize that perampanel will lead to a significant reduction in 
seizure frequency for adult patients with brain tumor-related seizures associated with high-grade 
glioma. 
We will compare seizure frequency before and 3 months after treatment with monotherapy and 
adjunctive PER and use descriptive statistics to demonstrate differences in responders. A P-value 
< 0.05 will be used to reflect statistical significance. 
 
Secondary Hypothesis 1: We hypothesize the progression of brain tumor (comparing 4 and 8 
mg/d of perampanel) based upon fusion by comparing baseline brain MRI and MRI at 12 months 
will be less for IDH-mutants. 
We hypothesize there will be minimal or no change in neurocognitive function from 0 to 3 
months on Montreal Outcome Cognitive Assessment (MOCA; higher scores indicating greater 
function); and the Clinical Global Impression of Change (CGIC; scores from 1 to 7, with lower 
scores indicating greater improvement and a score of 4 indicating no change). 
 
Chi-square and Student T-test will be used to measure differences in assessment and change 
during the study period. A P-value < 0.05 will be considered significant.

Interim Analysis 
 
An interim analysis will be performed when half of subjects are enrolled to assess the safety and efficacy 
of the study.  
7.3 
Subject Population(s) for Analysis 
 
Analysis of the protocol-compliant population will be conducted. 3, 6, and 12 month evaluability will be 
assessed based upon the severity of the glioma disease process associated with brain tumor-related focal 
seizures and risk of imminent death from high-grade malignant primary brain tumor.

8 Safety and Adverse Events 
8.1 
Definitions 
Unanticipated Problems Involving Risk to Subjects or Others (UPIRTSO) 
Any unanticipated problem or adverse event that meets the following three criteria:  
● Serious: Serious problems or events that results in significant harm, (which may be 
physical, psychological, financial, social, economic, or legal) or increased risk for the 
subject or others (including individuals who are not research subjects). These include: (1) 
death; (2) life threatening adverse experience; (3) hospitalization - inpatient, new, or 
prolonged; (4) disability/incapacity - persistent or significant; (5) birth defect/anomaly; (6) 
breach of confidentiality and (7) other problems, events, or new information (i.e. 
publications, DSMB reports, interim findings, product labeling change) that in the opinion 
of the local investigator may adversely affect the rights, safety, or welfare of the subjects 
or others, or substantially compromise the research data, AND 
● Unanticipated: (i.e. unexpected) problems or events are those that are not already 
described as potential risks in the protocol, consent document, not listed in the 
Investigator’s Brochure, or not part of an underlying disease. A problem or event is 
"unanticipated" when it was unforeseeable at the time of its occurrence. A problem or 
event is "unanticipated" when it occurs at an increased frequency or at an increased 
severity than expected, AND 
● Related: A problem or event is "related" if it is possibly related to the research procedures. 
 
 
Adverse Event 
An untoward or undesirable experience associated with the use of a medical product (i.e. drug, 
device, biologic) in a patient or research subject. 
Serious Adverse Event 
Adverse events are classified as serious or non-serious.  Serious problems/events can be well 
defined and include; 
● death 
● life threatening adverse experience 
● hospitalization 
● inpatient, new, or prolonged; disability/incapacity 
● persistent or significant disability or incapacity 
● birth defect/anomaly 
 
and/or per protocol may be problems/events that in the opinion of the sponsor-investigator 
may have adversely affected the rights, safety, or welfare of the subjects or others, or 
substantially compromised the research data. 
 
All adverse events that do not meet any of the criteria for serious, should be regarded as non-
serious adverse events.  
 
 
Adverse Event Reporting Period 

Adjunctive Anti-Seizure Medication in Epilepsy and High-grade Glioma 
Version 6.0 
 
 
Revised 23NOV2022 
Page 26 of 42 
William O. Tatum, IV, DO FAAN, FACNS 
CONFIDENTIAL 
For this study, the study treatment follow-up period is defined as 12 months following the last 
administration of study treatment.  
 
Preexisting Condition 
A preexisting condition is one that is present at the start of the study.  A preexisting condition 
should be recorded as an adverse event if the frequency, intensity, or the character of the 
condition worsens during the study period. 
 
General Physical Examination Findings 
At screening, any clinically significant abnormality should be recorded as a preexisting 
condition.  At the end of the study, any new clinically significant findings/abnormalities that 
meet the definition of an adverse event must also be recorded and documented as an adverse 
event.  
 
Post-study Adverse Event 
All unresolved adverse events should be followed by the sponsor-investigator until the events are 
resolved, the subject is lost to follow-up, or the adverse event is otherwise explained.  At the last 
scheduled visit, the sponsor-investigator should instruct each subject to report, to the sponsor-
investigator, any subsequent event(s) that the subject, or the subject’s personal physician, 
believes might reasonably be related to participation in this study.  
 
Abnormal Laboratory Values 
A clinical laboratory abnormality will be documented as an adverse event if the conditions of the 
laboratory are identified as outside the normal expected range for the parameter and in the 
investigators opinion requires an intervention (e.g., repeat testing, consequences on the disease 
state, exhibit evidence of organ toxicity, or necessitate dosage reduction, discontinuation of study 
drug, or additional follow-up).  
 
Hospitalization, Prolonged Hospitalization or Surgery 
Any adverse event that results in hospitalization or prolonged hospitalization should be 
documented and reported as a serious adverse event unless specifically instructed otherwise in 
this protocol.  Any condition responsible for surgery should be documented as an adverse event 
if the condition meets the criteria for an adverse event.  
 
Neither the condition, hospitalization, prolonged hospitalization, nor surgery are reported as an 
adverse event in the following circumstances:  
● Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures 
for a preexisting condition.  Surgery should not be reported as an outcome of an adverse 
event if the purpose of the surgery was elective or diagnostic and the outcome was 
uneventful. 
● Hospitalization or prolonged hospitalization required to allow efficacy measurement for 
the study. 
● Hospitalization or prolonged hospitalization for therapy of the target disease of the study, 
unless it is a worsening or increase in frequency of hospital admissions as judged by the 
clinical investigator.

8.2 
Recording of Adverse Events 
At each contact with the subject, the study team must seek information on adverse events by 
specific questioning and, as appropriate, by examination.  Information on all adverse events 
should be recorded immediately in the source document, also in the appropriate adverse event 
section of the case report form (CRF). All clearly related signs, symptoms, and abnormal 
diagnostic, laboratory or procedure results should be recorded in the source document. 
 
All adverse events occurring during the study period must be recorded.  The clinical course of 
each event should be followed until resolution, stabilization, or until it has been ultimately 
determined that the study treatment or participation is not the probable cause.  Serious adverse 
events that are still ongoing at the end of the study period must be followed up, to determine the 
final outcome.  Any serious adverse event that occurs during the Adverse Event Reporting 
Period and is considered to be at least possibly related to the study treatment or study 
participation should be recorded and reported immediately. 
 
8.3 
Reporting of Serious Adverse Events and Unanticipated Problems 
When an adverse event has been identified, the study team will take appropriate action necessary 
to protect the study participant and then complete the Study Adverse Event Worksheet and log.  
The sponsor-investigator will evaluate the event and determine the necessary follow-up and 
reporting required. 
8.3.1 Sponsor-Investigator reporting: notifying the Mayo IRB 
The sponsor-investigator will report to the Mayo IRB any UPIRTSOs and Non-UPIRTSOs 
according to the Mayo IRB Policy and Procedures. 
8.3.2 Sponsor-Investigator reporting: Notifying the FDA 
The sponsor-investigator will report to the sponsor and the FDA all unexpected, serious 
suspected adverse reactions according to the required IND Safety Reporting timelines, formats 
and requirements. 
 
Unexpected fatal or life threatening suspected adverse reactions where there is evidence to 
suggest a causal relationship between the study drug/placebo and the adverse event, will be 
reported as a serious suspected adverse reaction.  This will be reported to the FDA on FDA Form 
3500A, no later than 7 calendar days after the sponsor-investigator’s initial receipt of the 
information about the event. 
 
Other unexpected serious suspected adverse reactions where there is evidence to suggest a causal 
relationship between the study drug/placebo and the adverse event, will be reported as a serious 
suspected adverse reaction.  This will be reported to the FDA on FDA Form 3500A, no later than 
15 calendar days after the sponsor-investigator’s initial receipt of the information about the 
event. 
 
Any clinically important increase in the rate of serious suspected adverse reactions over those 
listed in the protocol or product insert will be reported as a serious suspected adverse reaction.

CONFIDENTIAL 
This will be reported to the FDA on FDA Form 3500A no later than 15 calendar days after the 
sponsor-investigator’s initial receipt of the information about the event. 
 
Findings from other studies in human or animals that suggest a significant risk in humans 
exposed to the drug will be reported.  This will be reported to the FDA on FDA Form 3500A, no 
later than 15 calendar days after the sponsor-investigators initial receipt of the information about 
the event. 
8.4 
Stopping Rules  
 
The Principal and Co-Investigators as well as Study Coordinator are responsible for individual 
safety monitoring. Stopping or interruption of the study may be necessary if a significant number 
of study participants develop unexpected clinical flaring or significant worsening, as judged by 
the principal investigator, study coordinator or sponsor, appears temporally linked with 
Perampanel administration to be used for the indication outlined in this protocol. 
 
The Principal Investigator and/or Investigators will review all adverse event reports to determine 
if specific reports need to be made to the IRB and FDA. For this study, all SAEs or possible 
UPIRTSOs will be reported to the IRB. 
8.5 
Medical Monitoring 
It is the responsibility of the Principal Investigator to oversee the safety of the study at his/her 
site.  This safety monitoring will include careful assessment and appropriate reporting of adverse 
events as noted above, as well as the construction and implementation of a site data and safety-
monitoring plan (see section 10  “Study Monitoring, Auditing, and Inspecting”).  Medical 
monitoring will include a regular assessment of the number and type of serious adverse events. 
 
9 Data Handling and Record Keeping 
9.1 
Confidentiality 
Information about study subjects will be kept confidential and managed according to the 
requirements of the Health Insurance Portability and Accountability Act of 1996 (HIPAA).  
Those regulations require a signed subject authorization informing the subject of the following:  
● What protected health information (PHI) will be collected from subjects in this study? 
● Who will have access to that information and why? 
● Who will use or disclose that information? 
● The rights of a research subject to revoke their authorization for use of their PHI.  
In the event a subject revokes authorization to collect or use PHI, the investigator, by regulation, 
retains the ability to use all information collected prior to the revocation of subject authorization.  
For subjects that have revoked authorization to collect or use PHI, attempts should be made to 
obtain permission to collect at least vital status (long term survival status that the subject is alive) 
at the end of their scheduled study period.

9.2 
Source Documents 
Source data is all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial.  Source 
data are contained in source documents.  Examples of these original documents, and data records 
include: hospital records, clinical and office charts, laboratory notes, memoranda, subjects’ 
diaries or evaluation checklists, pharmacy dispensing records, recorded data from automated 
instruments, copies or transcriptions certified after verification as being accurate and complete, 
microfiches, photographic negatives, microfilm or magnetic media, x-rays, subject files, and 
records kept at the pharmacy, at the laboratories, and at medico-technical departments involved 
in the clinical trial. 
9.3 
Case Report Forms 
The study case report form (CRF) is the primary data collection instrument for the study.  All 
data requested on the CRF must be recorded.  All missing data must be explained.  If a space on 
the CRF is left blank because the procedure was not done or the question was not asked, write 
“N/D”.  If the item is not applicable to the individual case, write “N/A”.  All entries should be 
printed legibly in black ink.  If any entry error has been made, to correct such an error, draw a 
single straight line through the incorrect entry and enter the correct data above it.  All such 
changes must be initialed and dated.  Do not erase or use “white-out” for errors.  For clarification 
of illegible or uncertain entries, print the clarification above the item, then initial and date it.  If 
the reason for the correction is not clear or needs additional explanation, neatly include the 
details to justify the correction. 
 
Data Management 
 
Study data will be collected and managed using REDCap electronic data capture tools hosted at 
Mayo Clinic. All data requested on the Case Report Form (CRF) will be recorded for each 
participant. A standardized CRF will be generated by REDCap. For any data query, the Principal 
Investigator and Investigators will meet to clarify the data queried and make corrections based on 
consensus.  
 
Data Security and Confidentiality 
 
Study subjects will be consented and evaluated within the Department of Neurology at Mayo 
Clinic Florida by designated study personnel. All study data will be stored in the password 
protected REDCAP database. Access to the REDCAP database will be limited to the Principal 
Investigator, Investigators and Statistician. Paper documents, including patient logs/diaries and 
case report forms, will be kept in a locked cabinet with access available only to the Investigators 
and Study Coordinator. 
 
Data Quality Assurance 
 
Once the study is completed, the Principal Investigator will randomly select 3 participants and 
compare the data documented for each on the CRF with what is entered into the REDCap 
database.

10.2 Auditing and Inspecting 
The investigator will permit study-related monitoring, audits, and inspections by the IRB, the 
sponsor, and government regulatory agencies, of all study related documents (e.g. source 
documents, regulatory documents, data collection instruments, study data etc.).  The investigator 
will ensure the capability for inspections of applicable study-related facilities (e.g. pharmacy, 
diagnostic laboratory, etc.). 
 
Participation as an investigator in this study implies acceptance of potential inspection by 
government regulatory authorities and applicable compliance offices. 
11 Ethical Considerations 
This study is to be conducted according to United States government regulations and 
Institutional research policies and procedures. 
 
This protocol and any amendments will be submitted to a properly constituted local Institutional 
Review Board (IRB), in agreement with local legal prescriptions, for formal approval of the 
study.  The decision of the IRB concerning the conduct of the study will be made in writing to 
the sponsor-investigator before commencement of this study. 
 
All subjects for this study will be provided a consent form describing this study and providing 
sufficient information for subjects to make an informed decision about their participation in this 
study.  This consent form will be submitted with the protocol for review and approval by the IRB 
for the study.  The formal consent of a subject, using the Approved IRB consent form, must be 
obtained before that subject undergoes any study procedure.  The consent form must be signed 
by the subject or the subject’s legally authorized representative, and the individual obtaining the

A subject’s capacity for consent will be determined by the attending physician and clinical team 
per standard of care assessments in conjunction with the research staff. Patients will continue to 
be assessed for their ability to consent and will be re-consented when deemed appropriate. 
 
The study staff will not obtain assent. If a patient lacks the capacity to consent for themselves, 
they will likely be unable to fully understand the study procedures. 
 
The Legally Authorized Representative (LAR) will be identified by the attending physician 
and/or case manager in accordance with standard of care practices. Obtaining consent from the 
LAR will follow the same guidelines as if the patient themselves were being consented.
