potential biomarker for seizure induced respiratory depression & 
modification by SSRI- a pilot study 
 
Précis: 
Double blind randomized phase II clinical trial. 
Patients with epilepsy either undergoing video EEG study or being planned 
for one, will be screened by HCVR test. Fourty subjects with a depressed 
response (slope <2.0 L/mim/mm Hg) will be randomized to either 
fluoxetine or placebo (1:1) 
 
Intervention will be for 6 weeks.  
 
Subjects will be enrolled in two different locations, EMU or neurology 
clinic. A follow up HCVR testing will be done at one month. 
Continuous VEEG, and comprehensive respiratory monitoring (chest & 
abdominal belts, oro-nasal pressure & thermistry, pulse oximeter and 
trancutanesous CO2 monitor) will be collected. 
Change in the HCVR before and after intervention in two groups will be 
compared to determine effect of the drug. Similarly, differenc in severity of 
peri-ictal respiratory abnormalities will be compared between two arms. 
    
Objectives: 
 
Primary Objective:  
To assess feasibility of successfully enrolling subjects 
 
Secondary Obective: 
To evaluate effect of fluoxetine on HCVR and peri-ictal respiratory 
depression in drug resistant epilepsy patients.

INTRODUCTION: BACKGROUND INFORMATION AND SCIENTIFIC 
RATIONALE  
 
2.1 
BACKGROUND INFORMATION  
Sudden unexpected death in epilepsy patients (SUDEP) ranks second only to stroke among neurological 
diseases in years of potential life lost (YPLL). While the specific mechanisms of death in SUDEP are not 
well understood, per-ictal respiratory dysfunction likely plays an important role in many cases. Seizure 
related respiratory depression of variable severity is commonly observed, and on rare instances may be 
fatal. There is a gap in our knowledge regarding the mechanisms responsible for peri-ictal respiratory 
dysfunction. A better understanding of these mechanisms would open the door to interventions to 
decrease the risk of SUDEP.  
Several lines of evidence support a critical role for the serotonergic system in central control of 
ventilation. Serotonin neurons in the raphe nuclei of the brainstem sense rising carbon dioxide and low 
pH, thereby stimulating breathing and arousal. These responses may serve as mechanisms that protect 
against asphyxia, particularly during sleep or the post-ictal state. In addition, data from animal and human 
studies also indicate that serotonin possesses independent anti-seizure properties. Finally, in mouse 
models of seizure-induced sudden death, pre-treatment with selective serotonin reuptake inhibitor (SSRI) 
agents prevents death following seizures. These observations led us to formulate our central hypothesis: 
that a subset of epilepsy patients has impaired central chemo-responsiveness as tested by the ventilatory 
response to inhalation of carbon dioxide (hypercapnic ventilatory response, HCVR), and this correlates 
with a greater degree of peri-ictal respiratory depression, thereby increasing the risk of terminal 
cardiorespiratory dysfunction and death. We further hypothesize that the administration of fluoxetine (an 
SSRI agent) to patients with a depressed HCVR will enhance CO2 sensitivity, and reduce the severity of 
peri-ictal respiratory depression.  
2.2 
RATIONALE  
Fluoxetine is an FDA approved drug commonly and safely used to treat depression, anxiety, obsessive 
compulsive disorder and eating disorders. Its toxicology has been well studied in animal and human. 
Fluoxetine has been used safely in human to modify HCVR in panic disorder population. However, it has 
been not studied yet in epilepsy population. We hypothesize that administration of fluoxetine (an SSRI 
agent) to patients with a depressed HCVR will enhance CO2 sensitivity, and reduce the severity of peri-
ictal respiratory depression.

2.3.1 KNOWN POTENTIAL RISKS  
 
Fluoxetine is a FDA approved antidepressant medicine which is used very frequently and safely. Some patients 
may experience some side effects that include: Nausea, diarrhea, anorexia, dry mouth, dyspepsia, insomnia, 
anxiety, nervousness, somnolence, tremor, decreased libido, abnormal dreams, headache, asthenia, flu like 
syndrome, fever, weight loss, Flatulence, constipation, rash, pruritus, abnormal vision etc. However, rare and 
serious side effects are also possible which include; worsening depression, increase suicidal thoughts or actions, 
mood swings, acting aggressive or violent, serotonin syndrome, severe allergic reaction- trouble breathing, 
swelling of face, tongue, eyes or mouth, rash, hives,  abnormal bleeding if you are taking blood thinner coumadin 
warfarin (Coumadin®), a non-steroidal anti-inflammatory drugs (NSAIDs, like Ibuprofen or naproxen), or 
aspirin, increase in seizure frequency and possible irregular heart rhythm called Torsades de pointes due 
prolonged QT. 
Fluoxetine is classified by FDA as category “C” for use in pregnancy which means there is a known risk of birth 
defect animal fetus but there are no adequate data and well-controlled studies in human.  
Stopping fluoxetine suddenly can cause serious symptoms including: 
• 
 
Anxiety, irritability, high or low mood, feeling restless or changes in sleep habits 
• 
 
Headache, sweating, nausea, dizziness 
• 
 
Shaking, confusion etc 
 
2.3.2 KNOWN POTENTIAL BENEFITS

STUDY DESIGN AND ENDPOINTS 
 
4.1 
DESCRIPTION OF THE STUDY DESIGN 
 
Double blind placebo-controlled randomized prospective trial 
Two enrolling locations: EMU and Neurology Clinic 
• 1)  To test effect of Fluoxetine on HCVR: Subjects will be screened in the EMU and neurology clinic. 
Subjects eligible are those with patients with epilepsy who have a reduced baseline HCVR slope 
(<2.0 L/min/mmHg). Subjects will be enrolled, and randomized to either fluoxetine or placebo 
(1:1) until 20 subjects complete the study. Investigational Drug Services (IDS), at the University 
of Iowa Hospitals and Clinics (UIHC), will be responsible for randomizing and dispensing the

drugs. Both fluoxetine and placebo will be encapsulated in identical casing to mask their identity. 
Both the subjects and the investigators will be blinded to the randomization process. A standard 
titration plan will consist of fluoxetine or placebo 10 mg per day for a week, then 20 mg per day 
for a week and then 40 mg per day for 2 weeks, upon discharge. Subjects will return after 4 
weeks for follow up HCVR testing in the Clinical Research Unit at UIHC. For each subject, the 
magnitude of post-treatment HCVR in terms of HCVR slope, minute ventilation, VRTCO2, time 
to VRTCO2 and time to target ETCO2 at the end of the study will be compared with their baseline 
HCVR. The medication adherence rate, safey concerns and change in mood scale will be assessed 
at follow up. Reported adverse effects will be collected for all subjects. Enrolment rate and study 
completion rates will also be assessed every 6 months.  
• 2)  To test effect of fluoxetine on peri-ictal respiratory depression: Subjects will be screened in 
neurlogy clinic from a group of previously diagnosed patients with epilepsy who are planned for 
VEEG study. Eligible subjects will undergo HCVR testing. Eligible subjects with a reduced 
baseline HCVR slope (<2.0 L/min/mmHg) will be enrolled and randomized to fluoxetine vs 
placebo (1:1) until a total of 20 subjects complete the study. Both the subjects and investigators 
will be blinded to the randomization process. A standard titration plan for fluoxetine & placebo 
will be as above, for 4 weeks prior to EMU admission. During EMU admission, the subjects will 
be monitored with VEEG, EKG, EMG, SpO2, tcCO2/ETCO2, oral & nasal thermistor & pressure 
transducer to measure airway pressure, and RIP with abdominal & chest belts to measure change 
in circumference during respiration. Peri-ictal respiratory changes in the two groups will be 
compared to assess the effect of fluoxetine.

STRATEGIES FOR RECRUITMENT AND RETENTION 
 
Patients, 18-75 year age, with epilepsy being treated at EMU & neurology clinic at the University of Iowa 
Hospital & Clinics will be screened for their eligibility for this study. Subjects with lack of consent 
capacity including severe mentally ill, prisoners, cognitive impaired, pregnant, children, prisoner, non 
English speaking and employee vounteers will be excluded from the study. 
 
Approximately, 100 subjects will undergo HCVR testing for screening;  Eligible subjects will be 
randomized to fluoxetine vs placebo, until each group has 20 completed subjects. 
Anticipated accrual rate: 2/month 
Number of sites and participants in US site: 1 
Source of participants and Recruitment venues: Patients, 18-75 year age, with  epilepsy being treated at 
EMU & neurology clinic at the University of Iowa Hospital & Clinics 
Types of advertisements planned: Emails with information regarding the study will be distributed among 
neurology physicians working at the University of Iowa Hospitals & Clinics. 
 
Subjects will be contacted via telephone as a part of study protocol followup which may improve 
retention. 
 
5.4 
PARTICIPANT WITHDRAWAL OR TERMINATION 
 
5.4.1 REASONS FOR WITHDRAWAL OR TERMINATION 
 
Participants are free to withdraw from participation in the study at any time upon request. 
An investigator may terminate participation in the study if: 
• 
Any clinical serious adverse events related or unrelated to the study. 
• 
The participant meets an exclusion criteria (either newly developed or not previously 
recognized) that precludes further participation. 
 
5.4.2 HANDLING OF PARTICIPANT WITHDRAWALS OR TERMINATION 
 
If the participant withdraws or terminates participation in the study prior to randomization to one of the 
intervention arms, no attempt for follow up will be made.  
 
If the participant withdraws or terminates participation in the study after randomization to one of the 
intervention, we will attempt to contact them via phone calls for safety follow up. No other outcome 
measures will be collected.  
 
If the participant in the study  develops serious adverse events (SAEs), they will be terminated from 
further participation in the study. They will be referred for appropriate evaluation and treatment (if 
already not being done). They will be followed up until resolution of the adverse events.

ASSESSMENT OF SAFETY 
 
8.1 
SPECIFICATION OF SAFETY PARAMETERS 
All serious and non serious adverse events will be recorded 
 
8.1.1 DEFINITION OF ADVERSE EVENTS (AE) 
 
Adverse event means any untoward medical occurrence associated with the use of an intervention, 
whether or not considered intervention-related. 
 
8.1.2 DEFINITION OF SERIOUS ADVERSE EVENTS (SAE) 
 
An AE or suspected adverse reaction is considered "serious" if, in the view of the investigator, it results in 
any of the following outcomes: death, a life-threatening adverse event, inpatient hospitalization or 
prolongation of existing hospitalization, a persistent or significant physical or mental incapacity including 
worsening depression, increase suicidal thoughts or actions, acting aggressive or violent , or a congenital 
anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, they may 
jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition. Examples of such medical events include allergic reactions including 
angioedema of face, tongue, mouth, and bronchospasm requiring intensive treatment in an emergency 
room or at home, or increased seizure frequency from baseline that do not result in inpatient 
hospitalization. 
 
8.1.3 DEFINITION OF UNANTICIPATED PROBLEMS (UP) 
 
Unanticipated problems (UP) per OHRP, are any incident, experience, or outcome that meets all of 
the following criteria:  
 
• Unexpected in terms of nature, severity, or frequency given (a) the research procedures that are 
described in the IRB-approved research protocol and informed consent document; and (b) the 
characteristics of the participant population being studied;  
 
• Related or possibly related to participation in the research (“possibly related” means there is a 
reasonable possibility that the incident, experience, or outcome may have been caused by the 
procedures involved in the research); and

Version 01.2 
Protocol:201607761 
06/28/2017 
 
 
 
17 
 
• Suggests that the research places participants or others at a greater risk of harm (including physical, 
psychological, economic, or social harm) than was previously known or recognized. This study will 
use the OHRP definition of UP 
 
8.2 
CLASSIFICATION OF AN ADVERSE EVENT 
 
8.2.1 SEVERITY OF EVENT 
 
For AEs not included in the protocol defined grading system, the following guidelines will be used to 
describe severity.  
• 
Mild – Events require minimal or no treatment and do not interfere with the participant’s daily 
activities.  
• 
Moderate – Events result in a low level of inconvenience or concern with the therapeutic 
measures. Moderate events may cause some interference with functioning.  
• 
Severe – Events interrupt a participant’s usual daily activity and may require systemic drug 
therapy or other treatment. Severe events are usually potentially life-threatening or incapacitating.  
 
8.2.2 RELATIONSHIP TO STUDY AGENT 
For all collected AEs, the clinician who examines and evaluates the participant will determine the 
AE’s causality based on temporal relationship and his/her clinical judgment. The degree of certainty 
about causality will be graded using the categories below.  
• 
Definitely Related – There is clear evidence to suggest a causal relationship, and other possible 
contributing factors can be ruled out. The clinical event, including an abnormal laboratory test result, 
occurs in a plausible time relationship to drug administration and cannot be explained by concurrent 
disease or other drugs or chemicals. The response to withdrawal of the drug (dechallenge) should be 
clinically plausible. The event must be pharmacologically or phenomenologically definitive, with use of a 
satisfactory rechallenge procedure if necessary. 
• 
Probably Related – There is evidence to suggest a causal relationship, and the influence of other 
factors is unlikely. The clinical event, including an abnormal laboratory test result, occurs within a 
reasonable time after administration of the drug, is unlikely to be attributed to concurrent disease or other 
drugs or chemicals, and follows a clinically reasonable response on withdrawal (dechallenge). 
Rechallenge information is not required to fulfill this definition.  
• 
Possibly Related – There is some evidence to suggest a causal relationship (e.g., the event 
occurred within a reasonable time after administration of the trial medication). However, other factors 
may have contributed to the event (e.g., the participant’s clinical condition, other concomitant events). 
Although an AE may rate only as “possibly related” soon after discovery, it can be flagged as requiring 
more information and later be upgraded to “probably related” or“definitely related,” as appropriate. 
• 
Unlikely to be related – A clinical event, including an abnormal laboratory test result, 
whosetemporal relationship to drug administration makes a causal relationship improbable (e.g., theevent 
did not occur within a reasonable time after administration of the trial medication) and inwhich other 
drugs or chemicals or underlying disease provides plausible explanations (e.g., theparticipant’s clinical 
condition, other concomitant treatments).

Version 01.2 
Protocol:201607761 
06/28/2017 
 
 
 
18 
• 
Not Related – The AE is completely independent of study drug administration, and/or 
evidenceexists that the event is definitely related to another etiology. There must be an 
alternative,definitive etiology documented by the clinician. 
• 
  
 8.2.3 EXPECTEDNESS  
PI, will be responsible for determining whether an AE is expected or unexpected. An AE will be 
considered unexpected if the nature, severity, or frequency of the event is not consistent with the risk 
information previously described for the study agent. 
 
8.3 
TIME PERIOD AND FREQUENCY FOR EVENT ASSESSMENT AND FOLLOW-
UP 
 
The occurrence of an AE or SAE may come to the attention of study personnel during study visits and 
interviews of a study participant presenting for medical care, or upon review by a study monitor. All 
AEs including local and systemic reactions not meeting the criteria for SAEs will be captured on the 
appropriate RF. Information to be collected includes event description, time of onset, clinician’s 
assessment of severity, relationship to study product (assessed only by those with the training and 
authority to make a diagnosis), and time of resolution/stabilization of the event. All AEs occurring 
while on study must be documented appropriately regardless of relationship. All AEs will be followed 
to adequate resolution.  
Any medical condition that is present at the time that the participant is screened will be considered as 
baseline and not reported as an AE. However, if the study participant’s condition deteriorates at any 
time during the study, it will be recorded as an AE. UPs will be recorded in the data collection system 
throughout the study.  
Changes in the severity of an AE will be documented to allow an assessment of the duration of the event 
at each level of severity to be performed. AEs characterized as intermittent require documentation of 
onset and duration of each episode.  
The PI will record all reportable events with start dates occurring any time after informed consent is 
obtained until 7 days after the last day of study participation. At each study visit/followup phone visit, the 
investigator will inquire about the occurrence of AE/SAEs since the last visit. Events will be followed for 
outcome information until resolution or stabilization. 
 
8.4 
REPORTING PROCEDURES 
 
8.4.1 ADVERSE EVENT REPORTING  
Adverse events that are serious will reported to independent medical examiner and IRB. 
 
8.4.2 SERIOUS ADVERSE EVENT REPORTING  
 
The study clinician will complete a SAE Form within the following timelines:

19 
• 
All deaths and immediately life-threatening events, whether related or unrelated, will be recorded 
on the SAE Form and submitted to the independent medical examiner within 24 hours of site awareness. 
See Section 1, Key Roles for contact information.  
• 
Other SAEs regardless of relationship, will be submitted to independent medical examiner within 
72 hours of site awareness.  
 
All SAEs will be followed until satisfactory resolution or until the site investigator deems the event to be 
chronic or the adherence to be stable. Other supporting documentation of the event may be requested by 
the independent medical examiner and should be provided as soon as possible. The principal investigator 
will be responsible for notifying IRB of any unexpected fatal or life-threatening suspected adverse 
reaction as soon as possible but in no case later than 7 calendar days after site awareness. 
 
8.4.3 UNANTICIPATED PROBLEM REPORTING  
 
Incidents or events that meet the OHRP criteria for UPs require the creation and completion of an UP 
report form. The investigator shall report UPs to the IRB and to the IME. The UP report will include 
the following information:  
• 
Protocol identifying information: protocol title and number, PI’s name, and the IRB 
projectnumber; 
• 
A detailed description of the event, incident, experience, or outcome; 
• 
An explanation of the basis for determining that the event, incident, experience, or 
outcomerepresents an UP; 
• 
A description of any changes to the protocol or other corrective actions that have been taken orare 
proposed in response to the UP. 
 
To satisfy the requirement for prompt reporting, UPs will be reported using the following timeline:  
• 
UPs that are lifethreatening or death, will be reported to the IRB and to the IME within 1 day of 
the investigator becoming aware of the event. But other SAEs, will be reported within 3 days of the 
investigator becoming aware of the event. 
• 
Any other UP will be reported to the IME only within 7 days of the investigator becoming aware 
of the problem. 
 
8.4.4 REPORTING OF PREGNANCY  
 
Women with potential for being pregnant will be screened to rule out active pregnancy using standard 
questionnaire and urinary pregnancy test. If pregnancy is reported by the participant while on study 
medicine, the medicine will be discontinued and she shall be referred for high risk obstetric clinic. 
 
Each pregnancy must be reported by the Investigator to the IME on the initial pregnancy report form 
within 30 days after becoming aware of the pregnancy. The Investigator must follow-up and 
document the course and the outcome of all pregnancies even if the subject was withdrawn from the 
clinical study or if the clinical study has finished.

All outcomes of pregnancy must be reported by the Investigator to the Sponsor on the pregnancy 
outcome report form within 30 days after he/she has gained knowledge of the normal delivery or 
elective abortion.  
 
8.5 
STUDY HALTING RULES  
 
Administration of study agent will be halted when three grade 3 (severe) AEs determined to be “probably 
related” are reported to the IME. The IME will notify the study sponsor and investigators immediately 
when the third grade 3 event is reported and enrollment screens will stop accepting new study 
participants. The study sponsor will provide the IME with AE listing reports within 24 hours. The IME 
will provide recommendations for proceeding with the study to the study sponsor. The study sponsor may 
inform the FDA of the temporary halt and the disposition of the study. 
 
8.6 
SAFETY OVERSIGHT 
 
Safety oversight will be under the direction of an independent medical examiner (IME). The IME will 
assess safety and efficacy data on each arm of the study. The IME will provide its input to IRB, sponsor 
and  principal investigator

10.4.2 ANALYSIS OF THE PRIMARY ENDPOINT(S) 
 
Enrollment rate: 
This will be assessed every 3 months until the end of the enrollment period.  It will be reported as number 
of participants enrolled per 3 months. It will also be reported as percentage of  all the patients screened. 
 
Retention rate: 
This will be assessed every 3 months. It will be reported as number of participants completed the study 
per protocol  per 3 months. It will also be reported as percentage of  all the patients screened. 
 
10.4.3 ANALYSIS OF THE SECONDARY ENDPOINT(S) 
 
Observations with missing data are dropped from those analyses involving data variable. 
 
Change in mood score using PHQ-9 score 
This will be analyzed as the difference in PHQ-9 scores from baseline to final measurement between drug 
and placebo. The mean and standard deviation estimates of the differences will be provided. 
 
Change in minute ventilation during HCVR testing: 
This will be analyzed as the difference in minute ventilation during HCVR testing from baseline to final 
measurement between drug and placebo. The mean and standard deviation estimates of the differences 
will be provided. 
 
Change in slope of HCVR 
This will be analyzed as the difference in slope of HCVR between drug and placebo. Using a linear mixed 
model, we will include a predictor that is the interaction between HCVR slope and the treatment group. 
The mean and standard deviation estimates of the differences will be provided. 
 
Difference in duration of abnormal breathing during periictal period: 
Mean duration of abnormal breathing during perictal periods between drug and placebo will be compared. 
The mean and standard deviation estimates of the differences will be provided. 
 
Difference in oxygen saturation during periictal period 
Mean drop in oxygen saturation during perictal period between drug and placebo will be compared. The 
mean and standard deviation estimates of the differences will be provided. 
 
Difference in CO2 level in periictal period 
Mean change in CO2 level in periictal period compared to pre seizure baseline will be compared between 
drug and placebo. The mean and standard deviation estimates of the differences will be provided. 
 
All the secondary outcome measures will be estimated using generalized linear mixed models (GLMMs), 
specifying an identity link for normally distributed data and the log link for right-skewed data. 
 
Since we are interested in obtaining estimates for future studies, we will not run non-parametric analyses, 
which only provide p-values.

two groups and tested using one tail t-test with type I error at 0.025 
 
 
10.4.4 SAFETY ANALYSES 
 
All the adverse events will be recorded. Severity and relationship to intervention will be determined as 
described in section 8.  Frequency of each adverse events will be compared between the two groups and 
tested using one tail t-test with type I error at 0.025. 
 
Adverse events leading to premature discontinuation from the study drug and serious treatment-emergent 
AEs should be presented either in a table.  
 
10.4.5 ADHERENCE AND RETENTION ANALYSES 
 
Adherence to the randomized intervention will be assessed by telephone interview and in person 
interview during follow up.  
 
10.4.6  BASELINE DESCRIPTIVE STATISTICS 
 
We plan to compare the baseline descriptive statistics between the treatment and control groups and 
establish if there is a significant difference of any variables. For continuous variables, a two sample t-test 
will be used to compare data that appear to be normally distributed (Wilcoxon Rank Sum test for skewed 
data). For categorical data, Pearson’s Chi-square test of independence will be used.

MEASURES TO MINIMIZE BIAS 
 
10.6.1 ENROLLMENT/ RANDOMIZATION/ MASKING PROCEDURES 
Subjects will be screened and enrolled in two locations, neurology clinic and EMU.  A total of 20 subject 
will be enrolled in each location and they will be randomized to drug vs placebo group equally (1:1) using 
computer generated random numbers. The assignment for each subject will be kept in a sealed envelope 
and will be provided to investigational drug pharmacy at the University of Iowa. 
The participants as well as the investigators (except one) will be blinded to the drug the participant is 
receiving. Bottles of the study drug will be labelled with the name of study, drug A or drug B, and 
instruction of titration plan.

INFORMED CONSENT PROCESS  
 
13.3.1 CONSENT/ASSENT AND OTHER INFORMATIONAL DOCUMENTS PROVIDED 
TO PARTICIPANTS 
 
 
Consent forms describing in detail the study agent, study procedures, and risks are given to the participant 
and written documentation of informed consent is required prior to starting any procedure/administering 
study product.  
 
Once the participant has signed the consent form, he/she will be asked to fill out “Iowa SSRI screening 
questionnaire, Iowa SSRI study questionnaire and PHQ-9 questionnaire”, as approved by IRB. 
 
12.3.2 CONSENT PROCEDURES AND DOCUMENTATION 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in the study 
and continues throughout the individual’s study participation. Extensive discussion of risks and possible 
benefits of participation will be provided to the participants and their families. Consent forms will be 
IRB-approved and the participant will be asked to read and review the document. The investigator and or

participants will receive a verbal explanation in terms suited to their comprehension of the purposes, 
procedures, and potential risks of the study and of their rights as research participants. Participants will 
have the opportunity to carefully review the written consent form and ask questions prior to signing. The 
participants should have the opportunity to discuss the study with their surrogates or think about it prior to 
agreeing to participate. The participant will sign the informed consent document prior to any procedures 
being done specifically for the study. The participants may withdraw consent at any time throughout the 
course of the trial. A copy of the informed consent document will be given to the participants for their 
records. The rights and welfare of the participants will be protected by emphasizing to them that the 
quality of their medical care will not be adversely affected if they decline to participate in this study.  
 
A record of consent will be filled out and scanned on the electronic health record of the subject.  
 
If a protocol amendment is required, the informed consent document and other study related 
questionnaires may need to be revised to reflect the changes to the protocol. If the informed consent & 
other study related questionnaires/documents is revised, it must be reviewed and approved by the 
responsible IRB, and signed by all subjects subsequently enrolled in the clinical study as well as those 
currently enrolled in the clinical study.
