Duration of Treatment and Study Duration:  There will be a total of 8 visits. 
 
Visit 1: Screening  
Visit 2: Baseline, randomization, and dispensation of SM 
Visit 3-8: Weekly assessment  
Visit 8: Final visit, Optional PK day, End of study assessments 
Total subject duration on study:  up to 8 weeks 
 
Enrollment is estimated to require approximately 4 months, and the study is expected to be completed 
approximately 6 months after enrollment begins. 
Treatment Schedule (Procedure):   
Screening (Visit 1):  Subjects will undergo initial screening evaluation after informed consent is obtained, 
including complete medical and psychiatric history, physical exam, serum pregnancy test (FOCP only), 
routine laboratory assessment and genetic testing for CYP2D6 enzyme activity, smoking status, and urine 
drug screen. Confirmation of ADHD will be performed with the CAADID and the CGI-S will be 
administered.  Study qualification requirements will be reviewed to confirm that the subject meets all 
inclusion and exclusion criteria.  
Baseline and Randomization and dispensation of SM (Visit 2): After a screening period of up to 14 days 
subjects will return to the investigational site and undergo their scheduled baseline assessment.  If their 
eligibility to participate in the trial is confirmed, subjects will be randomized (1:1) to receive a starting dose 
of 1x50 mg capsule TID (150 mg/day) of either SPN-812V or placebo.  Subjects will receive treatment at 
the 150 mg/day starting dose for one week.  Dosing is to start the morning after Visit 2.  Subjects who do 
not tolerate the starting dose will be discontinued from the study.  
Study Dose Treatment Phase (Visits 3 – 8): Subjects who tolerated the starting dose will then be titrated 
to receive a study dose of 2x50 mg TID (300mg/day) and continue this treatment regiment for five weeks.  
Subjects who, after titration to the study dose, do not tolerate treatment at 300 mg/day, will be allowed, at 
any time, to down-titrate the dose to the 150 mg/day starting dose and continue treatment at the same 
dose until completion of the study.  Subjects will return to the investigational site once a week to undergo 
safety and efficacy evaluations and to have SM compliance checked.  At the end of Visit 7, the subjects 
who have consented to participate in the optional PK sub study will receive a drug diary to record times of 
all weekly doses, will be instructed to fast the night before Visit 8, and will be instructed to not take SM 
that morning.  At Visit 8, subjects who agree to participate in the optional PK sub study will receive SM 
dose and will have blood drawn for PK assessments over approximately seven hours.  All rating scales 
will be administered prior to PK dosing and blood draws.  For subjects not participating in the optional PK 
sub study, their last dose will be taken the evening before the End of Study Visit (Visit 8).    
End of Study: At the end of the Visit 8 procedures or at early termination, subjects will complete end of 
study assessments. Subjects will return any unused capsules and undergo safety and efficacy 
evaluations if not already performed as part of that visit. 
Pharmacokinetic Sampling:  
Population PK data will be pooled across all subjects who participate in this optional portion of the study. 
On the final visit, there is an optional PK day.  All subjects who wish to participate will be dosed with 
active SM after an overnight fast and after all efficacy assessments are completed, Blood will be draw
for quantitative PK analysis according to the following schedule (all times +/- 30 minutes
n 
): 
Pre-dose and ½, 1, 2, 3, 4, 5, and 6 hours post-dose  
 
Although draw windows are given, efforts should be made to ensure that the time interval between any 
two sampling timepoints is not less than 30 minutes

Statistical Methods:   
Safety Analyses
The incidence rate of AEs will be calculated by treatment group for each SOC and preferred term.  The 
severity of the AEs and the relationship to SM will be summarized by treatment group for each SOC and 
preferred term.  
Descriptive statistics will be presented for the results from the clinical laboratory tests, vital signs, weight, 
ECGs, and physical examinations.  Statistical testing will be performed for some of the safety endpoints, 
but the resulting p-values will be used for descriptive purposes only, i.e., not for inferential purposes. 
1. Incidence summary (> 2%) of AEs (SOC, Preferred Term, Relationship, Severity) when compared 
to placebo after 6-week treatment with any SPN-812V dose 
2. Changes from baseline in biochemistry, hematology, and urinalysis values from baseline after 6-
week treatment with any SPN-812V dose 
3. Percent of change from baseline in biochemistry, hematology, and urinalysis values from baseline 
after 6-week treatment with any SPN-812V dose when compared to placebo after 6-week 
treatment with any SPN-812V dose 
4. Changes from baseline in blood pressure, heart rate, respiratory rate, and body temperature after 
6-week treatment with any SPN-812V dose 
5. Percent of change from baseline in blood pressure, heart rate, respiratory rate, and body 
temperature when compared to placebo after 6-week treatment with any SPN-812V dose 
6. 12-lead ECGs changes from baseline after 6-week treatment with any SPN-812V dose 
7. 12-lead ECGs percent of change from baseline when compared to placebo after 6-week 
treatment with any SPN-812V dose 
8. Normal or abnormal findings on physical examinations after 6-week treatment with any SPN-812V 
dose   
9. Rate of abnormal findings on physical examinations after 6-week treatment with any SPN-812V 
dose  when compared to placebo after 6-week treatment with any SPN-812V dose

Efficacy Analyses
Descriptive statistics will be presented for all efficacy variables by visit and treatment group.  
All significance tests will be performed at the 0.05 level. 
As down titration from 300mg to 150mg is allowed for subjects who cannot tolerate the maintenance 
dose, those subjects will be treated as part of the 300mg arm while analyzing the data. 
Primary Efficacy Analyses
The primary efficacy measure is the investigator-rated CAARS Total ADHD Symptom Score which is the 
sum of the Inattention and Hyperactivity/Impulsivity subscales (18 items rated on 4-point scale). 
The changes from baseline to the endpoint in the investigator-rated CAARS Total ADHD Symptom 
Scores will be compared between the two treatment groups using the Wilcoxon rank-sum test or the two-
sample t-test.  To confirm the results (sensitivity analysis), a mixed model repeated measures (MMRM) 
analysis will be conducted.  MMRM analysis will contain fixed effect terms for treatment, investigative si
visit, and interaction between treatment and visit.  The model will include post-baseline values of
investigator-rated CAARS Total ADHD Symptom Score as the dependent variable with a random patient 
effect and baseline investigator-rated CAARS Total ADHD Symptom Score as a covariate and will use an 
unstructured covariance.

Secondary Efficacy Analyses
1. Initial efficacy of SPN-812V starting dose (150 mg/day) when compared to placebo as measured 
by changes in the investigator-rated CAARS Total ADHD Symptom Score from baseline at week 
1 of treatment with starting dose will be analyzed with Wilcoxon rank-sum test or two-sample t-
test 
2. Effectiveness of any SPN-812V dose when compared to placebo as determined by the weekly 
changes in the Clinical Global Impression – Improvement (CGI-I) score from baseline severity for 
6-week treatment will be plotted as mean CGI-I change versus visit and analyzed using Wilcoxon 
rank-sum test or two-sample t-test 
3. Clinical utility of SPN-812V study dose (300 mg/day) when compared to placebo as determined 
by the investigator’s assessment of the changes in the CAARS score from baseline at week 2, 3, 
4, 5, and 6 of treatment will be analyzed with Wilcoxon rank-sum test or two-sample t-test 
4. Study subject’s perception of clinical benefit of SPN-812V study dose (300 mg/day) when 
compared to placebo as determined by changes in the self-rated CAARS score from baseline at 
endpoint after 5-week treatment will be analyzed with Wilcoxon rank-sum test or two-sample t-test
Subgroup Analyses for Efficacy
Subgroup analyses for efficacy will be performed on categories of the following measures: 
• 
Sex 
• 
Race 
for the ITT population for the investigator-rated CAARS Total ADHD Symptom Score.  Subgroup analyses 
will also be carried out for the following subscales 
• 
investigator-rated CAARS inattention subscale score 
• 
investigator-rated CAARS hyperactivity/impulsivity subscale score 
 
that together make up the CAARS Total ADHD Symptom Score 
Pharmacokinetic and/or Pharmacodynamic Analyses:  Population PK data will be pooled across all 
subjects who participate in this optional portion of the study and analyzed using nonlinear mixed-effects 
modeling methods. The objective of the population PK analyses is to derive individual-specific estimates 
of apparent oral clearance (CL/F) but not to fully characterize the PK of this formulation of Viloxazine.

7.  INTRODUCTION 
Viloxazine was previously marketed as an antidepressant in several European countries, since 
the 1970’s, and is currently under development by the Sponsor as SPN-812V, for its potential 
utility in treating adult attention deficit hyperactivity disorder (ADHD).  Viloxazine is a racemate 
and Supernus plans to develop the compound as such. Supernus intends to carry out this 
preliminary safety and proof of concept study in adult ADHD patients using an immediate 
release formulation that will support future development of a modified release formulation to 
facilitate compliance and possibly improve tolerability. 
 
Similar to tricyclic antidepressants and atomoxetine, viloxazine is an inhibitor of the reuptake of 
norepinephrine, but may also enhance the release of serotonin from neuronal stores. Clinical 
efficacy in Major Depressive Disorder has been shown at daily doses of 300 to 600 mg. 
Thorough published pharmacological and clinical summaries of the product are found in the 
reviews of Pinder et al., 1977 and Ban et al., 1980.  
 
Supernus development thesis is based on the current unmet medical need for effective long-
acting non-stimulant treatment for ADHD in adults.  Viloxazine can offer a compelling alternative 
to the use of scheduled substances to control ADHD thus limiting patients’ exposure to agents 
with potential for substance abuse.

This Phase I/IIa study seeks to evaluate the safety and tolerability of an immediate release 
formulation of viloxazine given three times per day (TID) at a dose of 150 or 300mg/day in 
adults.  A randomized, multicenter, parallel group, double-blind, placebo-controlled dose-ranging 
study design will be used.  50 subjects will be randomized; assuming a 20% dropout rate, it is 
anticipated that 40 subjects will complete the study.  Subjects will be monitored regularly for 
safety endpoints. 
Study Rationale 
Epidemiological data suggest that ADHD affects up to 8% of children in the USA while the 
estimated prevalence in the adult population is between 0.3 to 5%. (McCann, 2004). The 
increased recognition of ADHD as a disorder affecting adults has led investigators to focus on 
identifying 
pharmacological 
treatments 
for 
this 
age 
group. 
While 
stimulants, 
like 
methylphenidate, and amphetamine derivatives, are highly effective in ADHD with low risk of 
tolerance, they have significant adverse effects and a potential for abuse and illicit trafficking 
(Popper, 2000). Although stimulants are the mainstay of ADHD pharmacotherapy, atomoxetine 
is an FDA-approved non-stimulant selective noradrenergic re-uptake inhibitor considered a 
useful option for patients at risk of substance abuse, as well as for those who have co-morbid 
anxiety or tics, or who do not wish to take a controlled substance (Garnock-Jones, 2009-2010).  
Antidepressant drugs have also been shown to be effective in the treatment of ADHD (Slatkoff 
and Greenfield, 2006).  According to the literature, antidepressants with a wide range of receptor 
actions, efficacy, and side effects, including tricyclic antidepressants, noradrenergic, 
dopaminergic and 5-HT re-uptake inhibitors, can be helpful in controlling the ADHD symptoms.  
For instance reboxetine – an antidepressant registered in Europe with a mechanism of action 
supposedly very similar to viloxazine – has been claimed to have comparable efficacy to 
methylphenidate (Cohen-Yavin, 2009). Finally, the recently FDA-approved alpha-2 adrenergic 
agonist, guanfacine, has demonstrated efficacy in reducing hyperactivity and impulsivity in 
ADHD patients (Popper, 2000).  
 
After publishing fundamental research to clarify the mechanism of action of stimulants in ADHD, 
Arnsten, one of the key experts in this area, has summarized past and new results of 
neurobiological research on ADHD (Arnsten, 2006, 2009), suggesting an important role for 
prefrontal cortex (PFC) dysfunction. The PCF is critical for regulating so-called executive 
functions and for controlling attention and behavior.  Regulation of behavior is accomplished 
through networks of interconnected pyramidal cells which serve to store goals and rules guiding 
an individual’s actions.  The networks interact with each other and are highly dependent on their 
neurochemical 
environment. 
 
In 
particular, 
small 
changes 
in 
the 
catecholamines 
(norepinephrine) or dopamine can have marked effects on the PCF function.   It is not surprising 
that all drugs effective in ADHD, regardless of their mechanisms of action, modulate 
norepinephrine and dopamine release and optimize their concentrations at alpha (2A)-receptors 
and D (1) receptors respectively.  Serotonin has also been implicated in behavior modulation as 
suggested by some preclinical evidence generated in a rodent ADHD model.  Research 
conducted in young rats with neonatal hyperactivity induced by 6- hydroxydopamine (6-OHDA) 
lesioning indicates that behavioral effects of stimulants are mediated by release of both NE and 
serotonin (Davids, 2002).  These findings support the clinical testing of potential ADHD 
therapies that increase activity of the abovementioned neuromodulators.

The pharmacological similarity of viloxazine to other agents with proven efficacy in ADHD 
provides the rationale for a clinical trial to test preliminarily its effectiveness in this indication.  
While viloxazine inhibitory action on serotonin re-uptake appears to be weak, the drug does 
potentiate serotonin-mediated functions in mouse and rat (Ref: Lippman and Pugsley, 1976), 
and that feature might add interest to its pharmacological profile. 
 
Finally, the extensive human use of this product for depression has not generated any major 
safety concerns. Formulated as an extended-release product to overcome the molecule’s short 
half life, viloxazine may represent a novel approach to a polymorphic disease, for which more 
therapeutic options are still deemed necessary (Wigal, 2009).  
8.  STUDY OBJECTIVES 
Primary Objective 
The primary objective is to determine the safety of SPN-812V in adults with ADHD. 
Secondary Objectives 
The secondary objectives of this study are: 
• 
To determine the efficacy of SPN-812V in adults with ADHD  
• 
To explore the single dose and steady state pharmacokinetics of SPN-812V in adults 
with ADHD. 
9.  INVESTIGATIONAL PLAN 
9.1.  Overall Study Design and Plan 
This will be a multicenter, randomized, double-blind, placebo-controlled, parallel group study of 
the safety and efficacy in adults with ADHD.  The target subjects are healthy male or female 
adults aged 18 to 64 years, inclusive, with a diagnosis of ADHD.  A total of fifty subjects will be 
enrolled at approximately 5 sites in the US.  Subjects will be randomized (1:1) to one of two 
treatment groups, SPN-812V or placebo. 
The study will consist of a Screening Period (within 14 days prior to randomization) and a 
Dosing Period of 6 weeks,.  The total subject duration in the study will be up to 8 weeks as 
illustrated in Figure 1.

of vital signs and weight, PK blood sampling at Visit 8 (optional, if subjects wish to participate), 
and an ECG at Visit 4.  Assessments of concomitant medications, suicide risk, and SM 
compliance and dispensation will be performed.  Subjects who have consented to participate in 
the optional PK sub study will be given a diary at Visit 7 on which to record time of SM doses 
taken prior to Visit 8.  Subjects who are participating in the optional PK sub study will be given 
all efficacy assessments prior to blood draws or dosing on the PK day. For subjects not 
participating in the optional PK sub study, their last dose will be taken the evening before the 
End of Study Visit (Visit 8).    
9.1.3. End of Study Visit/Early Termination 
At the end of Visit 8, or prior to early discontinuation, subjects will undergo end of study 
assessments.  AEs will be monitored, and safety tests and efficacy scales will be administered 
unless assessments were performed earlier in the visit.  The procedures to be performed will 
include physical examination, collection of vital signs, weight, ECG, blood collection for 
hematology and chemistry, urine collection for urinalysis, drug screen, and pregnancy test (for 
FOCP).  Assessments of concomitant medications and SM compliance will be performed.   
9.2.  Discussion of Study Design, Including Choice of Treatment Groups and 
Appropriateness of Measurements 
This will be a randomized, double-blind, multicenter, parallel group, placebo-controlled safety 
and tolerability study in adults with ADHD.  The target subjects are healthy male and female 
adults aged 18 to 64 years, inclusive, with a diagnosis of ADHD.  50 subjects will be 
randomized; assuming a 20% dropout rate, it is anticipated that 40 subjects will complete the 
study.   
Blinding to treatment will be employed to reduce potential bias during data collection and 
evaluation of endpoints.  Randomization will be used in this trial to avoid bias in the assignment 
of subjects to treatment, to increase the likelihood that known and unknown subject attributes 
(e.g., demographics and baseline characteristics) are evenly balanced across treatment groups, 
and to enhance the validity of statistical comparisons across treatment groups.   
The primary objective of this Phase I/IIa study is to evaluate the safety of SPN-812V in these 
subjects.  Safety will be assessed by the monitoring of AEs, vital signs, clinical laboratory tests, 
physical examinations, and ECGs.   
The secondary endpoints of this study are: 
1. To establish the efficacy of SPN-812V over a 5-week treatment period with SPN-812V 
300 mg/day 
2. To establish the initial efficacy of SPN-812V after a 1-week treatment period with SPN-
812V 150mg/day. 
3. To establish the effectiveness of SPN-812V over a 6-week treatment period with either 
SPN-812V dose. 
4. To establish the clinical utility of SPN-812V after a 5-week treatment period with SPN-
812V 300mg/day. 
5. To establish the study subject’s perception of clinical benefit of SPN-812V at endpoint 
after a 5-week treatment with SPN-812V at 300mg/day.

6. To explore in a population model the single-dose and steady state pharmacokinetics of 
SPN-812V in adults with ADHD. 
 
To determine the drug effect on reducing ADHD symptoms, the CAARS will be utilized.  The 
CGI Scale will be administered to reflect drug effect on global functioning.  These efficacy 
assessments will be performed at all study visits.  Subjects who have agreed to participate in the 
optional PK sub study will have the efficacy assessments performed prior to blood being drawn 
and dosing for the PK sub study. 
Randomization will be used in this trial to avoid bias in the assignment of subjects to treatment, 
to increase the likelihood that known and unknown subject attributes (e.g., demographics and 
baseline characteristics) are evenly balanced across treatment groups, and to enhance the 
validity of statistical comparisons across treatment groups.   
9.3.  Selection of Study Population 
This study population was selected to evaluate SPN-812V safety and efficacy in adults, aged 18 
to 64 years old, inclusive, with ADHD.  In this study 50 subjects will be randomized at 
approximately 5 US sites.

Self-rated Conners’ Adult ADHD Rating Scale (CAARS)  
This assessment will be administered at study visits 2 and 8. 
 
9.4.3. Pharmacokinetic Measurements 
On the morning of Visit 8, all subjects who wish to participate in the optional PK day will 
arrive at the clinic after an overnight fast and will have all efficacy assessments 
administered first.  The subjects then will have a pre-dose PK sample taken, and be 
administered either 2 x 50mg SPN-812V capsules or will be administered 1 x 50mg 
SPN-812V capsule for subjects who underwent dose reduction. PK sampling will occur 
pre-dose and at 0.5, 1, 2, 3, 4, 5, and 6 hours post-dose.  Although there is a 30 minute 
window on draw times, efforts should be made to ensure that the time interval between 
any two sampling timepoints is not less than 30 minutes. Subjects may eat two hours 
after dosing.   
SPN-812V concentrations in plasma samples will be determined by the Sponsor using a 
validated chromatographic method.  The amount of blood to be drawn at each timepoint 
to determine the plasma concentrations of SPN-812V is 4mL.  Information regarding 
sample collection, handling, and shipping procedures will be detailed in a separate 
manual. 
Single dose administration of viloxazine hydrochloride (100mg) to ten healthy volunteers 
resulted in mean Cmax near 1800 ng/mL for viloxazine at a mean Tmax ~100 min post-
dose and with elimination half-life ~3 hr (Vandel B. et al., “Pharmacokinetics of viloxazine 
hydrochloride in man,” European Journal of Drug Metabolism and Pharmacokinetics, 
1982, Vol 7, pp. 65-68).  Timepoints were chosen on the basis of these data to inform 
both absorption and elimination phases of the viloxazine time course while minimizing 
the sampling burden on patients.  The design of the study provides both first-dose (in 
placebo group) and steady state (in active group) observations, albeit in parallel 
treatment groups. 
 
9.4.4. Safety Assessments 
Safety assessments during the study will consist of AE and SAE monitoring, weight, 
clinical laboratory tests, vital signs, physical examinations, and 12-lead ECGs, as 
detailed in section 9.4.1.   
9.4.4.1. 
Adverse Events 
As defined by the ICH Guideline for GCP, an AE is any untoward medical occurrence in 
a patient or clinical investigation subject administered a pharmaceutical product, which 
does not necessarily have to have a causal relationship with treatment.

An AE can be: 
• 
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal product, 
whether or not considered related to the medicinal product. 
• 
Any new disease or exacerbation of an existing disease. 
• 
Any deterioration in non-protocol-required measurements of laboratory value or other 
clinical test (e.g., ECG or X-ray) that results in symptoms, a change in treatment, or 
discontinuation from SM. 
• 
Recurrence of an intermittent medical condition (e.g., headache) not present at 
baseline. 
AEs fall into the categories of “non-serious” and “serious”.  Surgical procedures are not 
AEs; they are therapeutic measures for conditions that require surgery.  The condition 
for which the surgery is required is an AE, if it occurs or is detected during the study 
period.   
AEs or SAEs that are ongoing at the subject’s last study visit must be followed until 
resolution or if, in the medical judgment of the Investigator, the event has stabilized or is 
assessed as chronic.   
9.4.4.1.1. Reporting of Adverse Events 
All subjects will be closely questioned regarding the occurrence of AEs. 
For subjects who receive SM, all AEs (learned of through spontaneous reports or subject 
interview) will be collected starting from the first dose of SM until the end of the study.  
All AEs will be collected on the AE Case Report Form (CRF).  All SAEs will be reported 
to the Sponsor.   
A cluster of signs and symptoms that results from a single cause may be reported as a 
single AE (e.g., fever, elevated WBC, cough, abnormal chest X-ray, etc. can all be 
reported as “pneumonia”). 
9.4.4.1.2. Criteria for Assessing Severity 
The Investigator will evaluate the comments of the subject and the response to 
treatment in order that he/she may judge the true nature and severity of the AE.  
Severity refers to the accumulated intensity of discomfort / impairment of health since 
the last recording of AEs and will be assessed according to the following criteria: 
Mild:  Awareness of sign, symptom, or event, but easily tolerated 
Moderate: Discomfort enough to interfere with usual activity and may warrant 
intervention 
Severe:  Incapacitating with inability to do usual activities or significantly affects clinical 
status and warrants intervention

The criteria for assessing severity are different from those used for seriousness (see 
Section 9.4.4.2. for the definition of an SAE). 
9.4.4.1.3. Criteria for Assessing Causality 
The question of the relationship of an AE to SM should be determined by the 
Investigator or study physician after thorough consideration of all facts that are available.  
Assessment of causality is based on considering associative connections (time or 
place), pharmacological explanations, previous knowledge of the drug, presence of 
characteristic clinical or pathological phenomena, exclusion of other causes, and/or 
absence of alternative explanations.  The causal relationship of an AE to SM will be 
assessed according to the following criteria (based on World Health Organization [WHO] 
definitions): 
The Investigator is responsible for determining the relationship between the 
administration of SM and the occurrence of an AE as not suspected or suspected.  
• 
Not suspected: The temporal relationship of the AE to SM administration makes 
a causal relationship unlikely, or other drugs, therapeutic interventions, or 
underlying conditions provides a sufficient explanation for the observed event.  
• 
Not related:  Temporal relationship to SM administration is missing or 
implausible, or there is an evident other cause. 
• 
Unlikely related:  Temporal relationship to SM administration makes a causal 
relationship improbable; and other drugs, chemicals, or underlying disease 
provide plausible explanations 
• 
Suspected: The temporal relationship of the AE to SM administration makes a 
causal relationship possible, and other drugs, therapeutic interventions, or 
underlying conditions do not provide a sufficient explanation for the observed 
event.  
• 
Possibly related:  Reasonable time sequence to administration of SM, but event 
could also be explained by concurrent disease or other drugs or chemicals.  
Information on drug withdrawal may be lacking or unclear. 
• 
Definitely related: Plausible time relationship to SM administration; event 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 definitive pharmacologically or phenomenological, using a satisfactory 
rechallenge procedure if necessary. 
9.4.4.2. 
Serious Adverse Events 
A SAE is any untoward medical occurrence that at any dose: 
• 
results in death; 
• 
is life-threatening (i.e., the subject was at immediate risk of death from the AE 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; or 
• 
is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
SM) 
• 
is a medically important event or reaction (see below) 
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.  Examples of such 
events are intensive treatments in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias, or seizures that do not result in hospitalization, or 
development of drug dependency or drug abuse.  These events may be considered to 
need rapid reporting by the Sponsor to regulatory authorities (see Section 9.4.4.2.2.). 
Any new SAEs reported by the subject that occur after the first dose of SM and until the 
end of the study will be collected.  SAEs that are ongoing at the subject’s last study visit 
must be followed until resolution or if, in the medical judgment of the Investigator, the 
event has stabilized or is assessed as chronic.   
9.4.4.2.1. Reporting of SAEs 
All SAEs must be reported to the Safety Contact person(s) within 24 hours of first 
becoming aware of the SAE.  The Investigator must complete an SAE Form, including a 
detailed description of the SAE and all other information available (e.g., hospital records, 
autopsy reports and other relevant documents).  The Investigator must inform the IRB 
about such AEs in accord with ICH guidelines and the practices of the governing IRBs 
(Section 5.1.). 
Follow-up information, or new information available after the initial report, should be 
actively sought and reported to the Sponsor as it becomes available using the SAE 
Form. 
Safety Contact persons and all contact information are listed in the Site Manual and/or 
Regulatory Binder provided to each investigational site. 
9.4.4.2.2. Other Events Requiring Immediate Reporting 
The Investigator must report a pregnancy that occurs in a subject during a clinical study 
to the Medical Monitor within 24 hours of first becoming aware of the event.  The 
Investigator should discuss the case with the Medical Monitor; the Investigator must 
follow any pregnant subject for 3 months after the child is born.  Any AEs concerning the 
pregnancy of the subject during pregnancy or the child after birth must be documented 
and reported to the Sponsor.

9.4.4.2.3. Expedited Reporting 
The Sponsor will inform Investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (i.e., within 
specific timeframes).  For this reason, it is imperative that investigational sites submit 
SAE information to the Sponsor (or designee) in the manner described above. 
9.4.4.3. 
Laboratory Measurements 
Clinical laboratory tests will be performed by a central laboratory.  Information regarding 
collecting, handling, and shipping samples will be detailed in a separate manual.  The 
Schedule of Visits and Procedures (Table 1.  Schedule of Visits and Procedures) shows 
the time points at which blood and urine will be collected for clinical laboratory tests.   
For subjects who participate in the optional PK portion of the study, a total of 
approximately 32mL (8 PK blood draws × 4mL) of blood/subject will be taken during the 
course of the study for the purpose of PK samples, in addition to 29mL (2 blood draws 
for clinical chemistry × 14.5mL) required for laboratory tests for all subjects.  A complete 
list of all clinical laboratory assessments is presented in Table 2.  Clinical Laboratory 
Assessments. 
Laboratory personnel contact information and laboratory sample shipment information 
and instructions are listed in the Site Manual and/or Regulatory Binder provided to each 
investigational site.

Medical, Psychiatric History and Physical Examinations 
Medical and psychiatric history, including smoking history, will be taken at the screening 
visit.  Physical examinations will be performed at the Screening Visit and Final Visit as 
designated on the Schedule of Visits and Procedures (Table 1.  Schedule of Visits and 
Procedures). 
9.4.4.6. 
Electrocardiograms (ECGs) 
ECGs (12-lead) will be obtained at the Screening Visit, Visit 4, and the Final Visit as 
designated on the Schedule of Visits and Procedures (Table 1.  Schedule of Visits and 
Procedures).  Additional ECGs may be performed at other times if deemed necessary. 
The ECG will be recorded while the subject is resting in a supine position.  The ECG will 
electronically measure the PR, QRS, QT, and QTc intervals, and heart rate. 
All ECG tracings will be reviewed within 24 hours by the Investigator or qualified Sub-
Investigator.  PR intervals will be determined for each of these ECGs from a single 
reading.  Invalid measurements will be repeated.  QTc will be reported as QTcF (QT 
corrected using Fridericia's method). 
9.4.5. Completion/Discontinuation of Subjects 
Subjects will be permitted to leave the study at any time.  Subjects can be withdrawn 
from the study in any of the following circumstances: 
• 
SAE or an AE 
• 
Administrative reasons (e.g., sponsor decision) 
• 
Withdrawal of consent/assent 
• 
If the subject becomes pregnant  
• 
If it is in the best interest of the subject, in the opinion of the Investigator 
• 
Termination of the study 
When an event such as a family emergency, a transient illness (such as a cold) 
unrelated to SM, or a remediable act of non-compliance prevents a subject from 
participating in a scheduled visit, but the subject wishes to continue in the study, the 
Investigator will attempt to reschedule the visit and retain the subject in the study on a 
case by case basis, rather than discontinue the subject’s participation. 
If a subject is prematurely discontinued from participation in the study for any reason 
after SM administration, the Investigator must make every effort to perform the Final Visit 
assessments.

9.5.  Treatments 
9.5.1. Treatments Administered 
SM will be dispensed at each visit during the Randomization and Dose Treatment 
Periods.  Subjects will receive a bottle at each visit containing the correct number of 
50mg (or placebo) capsules, which is a sufficient number of capsules for dosing until the 
next visit. The SM will be taken by the subject orally, three times per day during waking 
hours, with at least 4 hours between doses (morning, noon, and evening).  
At Visit 8, subjects who agree to participate in the optional PK sub study will be given 2 x 
50mg SPN-812V capsules on-site in the morning, unless the subject had been down-
titrated, in which case, the subject will receive 1 x 50mg SPN-812V capsule on-site in 
the morning.  Note: all subjects who participate in the optional PK sub study will be given 
active SPN-812V capsule(s) in this portion. For subjects not participating in the optional 
PK sub study, their last dose will be taken the evening before the End of Study Visit 
(Visit 8).    
9.5.2. Identity of Study Medication 
SM are supplied as size 0 white opaque capsules by the Sponsor in labeled bottles.  
There will be 50 capsules per bottle.  Labels will bear the protocol number, product code, 
and batch number. SM will be repackaged each week into a weekly supply by the 
unblinded site staff member who will be dispensing the blinded medication.  The site 
number, subject number, subject initials, and the number of capsules to be taken at each 
dose per day, will be handwritten on the labels by the unblinded staff member who will 
be dispensing the blinded medication. 
9.5.3. Handling of Study Medication 
All SM will be supplied to the Investigator by the Sponsor.  SM supplies must be kept in 
an appropriate secure area (e.g., locked cabinet) and stored according to the conditions 
specified on the SM labels.  The Investigator must maintain an accurate record of the 
shipment and dispensing of the SM in an accountability log, a copy of which must be 
given to the Sponsor at the end of the study.  An accurate record of the date and amount 
of SM dispensed to each subject must be available for inspection at any time.  The 
assigned unblinded CRA will review these documents on one or more visits to the 
investigational site. 
All SM supplies are to be used only for this protocol and not for any other purpose.  The 
Investigator must not destroy any SM labels or any partly used or unused SM supply.  At 
the conclusion of the study and as appropriate during the course of the study, the 
Investigator will return all used and unused SM containers and a copy of the completed 
SM accountability log to the Sponsor.   
9.5.4. Study Medication Accountability 
The Investigator, who will be blinded, will delegate responsibility to a qualified unblinded 
study staff member who will be responsible for the accountability of all clinical supplies 
(receipt, dispensing, inventory, record keeping, and return) following Sponsor 
 

Supernus Pharmaceuticals, Inc.

instructions and must adhere to GCP guidelines as well as municipal, state, and federal 
regulations. 
Under no circumstances will the Investigator or the delegated unblinded staff member 
allow the SM to be used other than as directed by this protocol.  Clinical supplies will not 
be dispensed to any individual who is not enrolled in the study. 
An accurate and timely record of the receipt of all clinical supplies, dispensing of SM to 
the subject, collection of unused supplies returned by the subject at each visit, and 
subsequent return of unused SM to the Sponsor must be maintained.  This includes, but 
may not be limited to: (a) documentation of receipt of clinical supplies, (b) SM 
dispensing/return reconciliation log, (c) SM accountability log, and (d) all shipping 
service receipts.  All forms will be provided by the Sponsor.  Any comparable forms that 
the investigational site wishes to use must be approved by the Sponsor.  Discrepancies 
on SM accountability must be documented and addressed by the delegated unblinded 
staff member.    
The supplies and inventory records must be made available, upon request, for 
inspection by the designated representative of the Sponsor or a representative of the 
Food and Drug Administration (FDA).  All unused SM, including empty containers, are to 
be returned to the Investigator by the subject or parent or LAR, and ultimately to the 
Sponsor at the conclusion of the study, unless provision is made by the Sponsor for 
destruction of supplies and containers at the investigational site.  Upon completion of SM 
accountability and reconciliation procedures by investigational site personnel and 
documentation procedures by Sponsor personnel, SM that is to be returned to the 
Sponsor must be shipped following all local regulatory and shipment laws.  Forms and 
information that could unblind the study must be maintained such that the Investigator 
and blinded study staff are not unblinded. 
9.5.5. Method of Assigning Subjects to Treatment Groups 
The randomization for this study will be managed centrally; specific instructions to 
conduct subject randomization will be provided in a separate document to all 
investigational sites. 
A randomization scheme will be generated using a pseudo-random number generator in 
a computer program.  The method avoids bias by use of a chance mechanism.  The 
randomization scheme assigns Treatment 1 or Treatment 2 to each randomization 
number in a 1:1 ratio. 
Upon admission to the study, subjects will be assigned a 4-digit screening number, in 
the order that they are entered.  Subjects who subsequently meet all eligibility criteria will 
be assigned a 6-digit randomization number.  The first 3 digits will refer to the site, and 
the last 3 will refer to the subject-specific number, which will be assigned according to 
the randomization scheme.  
Once a randomization number has been assigned, no attempt should be made to use 
that number again, if, for example, a subject is withdrawn.  All subjects are randomized 
only once.

Note:  all subjects who participate in the optional PK substudy will be given active SPN-
812V capsule(s) in this portion. 
9.5.6. Removal of Subjects from Therapy or Assessment 
The Investigator or subjects themselves may stop SM treatment at any time for safety or 
personal reasons.  If possible, a subject who discontinues treatment will be followed for 
end of study protocol-specified visits and procedures.  A subject removed from the study 
for any reason may not be replaced. 
9.5.7. Dosing Schedule 
At the Baseline and Randomization Visit, subjects will be randomized to 
Treatments 1 or 2 and will initiate dosing.  Once the target dose is reached, maintenance 
treatment will continue for 6 weeks.  Down titration to the starting dose is allowed for 
subjects who cannot tolerate the maintenance dose, at the discretion of the Investigator 
in consultation with the Medical Monitor.  Subjects who cannot tolerate study drug after 
dose-reduction should be removed from the study. 
At Visit 8, subjects who agree to participate in the optional PK sub study will be 
administered efficacy assessments prior to dosing.  Then, subjects will be given 
2 x 50mg SPN-812V on-site in the morning, unless the subject had been down-titrated, 
in which case, the subject will receive 1 x 50mg SPN-812V on-site in the morning. 
9.5.8. Method of Administration 
Capsules should be swallowed whole and not crushed or chewed.  The SM will be 
administered three times per day, with at least 4 hours between doses (morning, noon, 
and evening).  When possible, doses should be administered at the same times each 
day.  If a dose is missed, it should be taken as soon as possible unless it is within 
30 minutes of the next dose; in this case the subject should skip the missed dose and 
return to the regular schedule thereafter. 
9.5.9. Blinding 
The appropriate SM, according to randomization, will be placed into bottles to be 
dispensed to the subject by an unblinded staff member (e.g., coordinator or pharmacist).  
Identity of treatment arm must not be disclosed to the site’s blinded study staff or the 
Sponsor (or designee).  An unblinded Clinical Research Associate (CRA) will monitor the 
SM records. 
9.5.10. 
Concomitant Medications 
For subjects who receive SM, concomitant medications and therapies that are ongoing 
as of the date of informed consent will be recorded on the Concomitant Medication CRF.  
The Investigator will record all concomitant medications, including over-the-counter 
medications, on the Concomitant Medication CRF.  The Investigator will record the AE 
for which the concomitant medication was administered on the AE CRF.

Treatment Compliance 
Records of SM and doses administered will be kept during the study by unblinded site 
staff.  The unblinded CRA will review SM accountability during investigational site visits 
and at the completion of the study. 
9.5.10. 
Change of Study Medication Dose 
Subjects will be assigned to 1 of 2 treatment groups.  All subjects will titrate to the 
maintenance dose of SM and will remain on SM for 6 weeks during the Maintenance 
Period.  Down titration to the starting dose is allowed for subjects who cannot tolerate 
the maintenance dose, at the discretion of the Investigator in consultation with the 
Medical Monitor.  Subjects who cannot tolerate study drug after dose-reduction should 
be removed from the study. 
9.6.  Data Quality Assurance 
This study will be organized, performed, and reported in compliance with the protocol, 
Standard Operating Procedures (SOPs), working practice documents, and applicable 
regulations and guidelines.  Site visit audits may be made periodically by the Sponsor or 
CRO’s qualified compliance auditing team, which is an independent function from the 
study conduct team. 
9.6.1. Data Collection 
The Investigator (or designee) will enter the information required by the protocol into the 
CRF in accordance with the CRF Completion Instructions that are provided with the 
CRF.  The CRA will visit each investigational site as frequently as documented in the 
monitoring plan to review the CRF for completeness and accuracy against the source 
documents.  The CRA will highlight any discrepancies found in the documentation of 
study conduct and ensure that appropriate site personnel address the discrepancies.  
Procedures for data collection and correction will be discussed at the site initiation visit, 
routine monitoring visits, and will be included in the completion instructions. 
9.6.2. Clinical Data Management 
Data from the CRF and other external data (e.g., laboratory data) will be entered into or 
transferred to a clinical database as specified in the data management plan for this 
study.  Quality control and data validation procedures will be applied to ensure the 
validity and accuracy of the clinical database. 
9.6.3. Database Quality Assurance 
The clinical database will be reviewed and checked for omissions, apparent errors, and 
values requiring further clarification using computerized and manual procedures.  Data 
queries requiring clarification will be documented and returned to the investigational site 
for resolution.  Only authorized personnel will make corrections to the clinical database, 
and all corrections will be documented in an audit trail.  A quality assurance audit will be 
performed prior to database lock.

9.6.4. Bioanalytical Data Management and Quality Control 
PK samples and requisition forms will be shipped by the Investigator to the central 
laboratory, and instructions will be detailed in the central laboratory manual.  Analysis 
will be performed by means of a validated chromatographic method.  Details on the 
analytical methodology, the method validation, and the analytical within-study quality 
control procedures will be included in the clinical study report for this protocol. 
9.7.  Statistical Methods 
9.7.1. Statistical and Analytical Plans 
Tabular summaries of the data collected during the study will be presented to provide a 
general description of the subjects studied and an overview of the safety, efficacy, and 
PK results.  Data from all investigational sites will be combined in the computation of 
these summaries, and summaries will be presented by treatment group.   
 
As down titration from 300mg to 150mg is allowed for subjects who cannot tolerate the 
maintenance dose, those subjects will be treated as part of the 300mg arm while 
analyzing the data. 
 
Continuous variables will be summarized using descriptive statistics (number of 
subjects, mean, standard deviation, median, and minimum and maximum values).  
Categorical (nominal) variables will be summarized using frequency tables (number and 
percentage of subjects in each category).  
 
In addition to tabular summaries, subject data listings, as specified in Sections 16.2 and 
16.4 of ICH E3, will be provided.  Additional subject data listings to be provided for this 
study are listed under the relevant subsections below. 
 
The full data analyses will be performed by the CRO after the study is completed and the 
database is locked.  Statistical programming and analyses will be performed using SAS® 
and/or other validated statistical software as required. 
 
The statistical analyses described in this section will be described in more detail in the 
Statistical Analysis Plan (SAP), which will be finalized prior to database lock and will be 
included in the clinical study report for this protocol.  The final SAP will take into account 
any amendment to the protocol. 
9.7.1.1. 
Analysis Populations 
The safety population consists of all randomized subjects who take at least one dose of 
SM. 
The intent-to-treat (ITT) population consists of all randomized subjects who took at least 
one dose of SM (i.e., the safety population), had baseline efficacy assessment, and had 
at least one post-baseline efficacy assessment.  
 The ITT population is the population for the efficacy analysis.  Subjects will be analyzed 
according to treatment assigned.

______________________________________________________________________ 
 
The restricted ITT population consists of all ITT population subjects with at least 1 
efficacy assessment after three weeks of treatment. 
The PK population consists of all Safety population subjects with an evaluable PK 
profile. 
9.7.1.1.1. Demographic/Baseline Analyses 
Demographic/baseline variables include age, sex, ethnicity, race, baseline height, 
baseline weight, and medical history.  Tabular summaries of the demographic/baseline 
variables will be presented for the safety, ITT, and restricted ITT populations, except for 
medical history, which will be summarized for the safety population only.   
9.7.1.1.2. Study Medication 
Tabular summaries of the treatment percent compliance rate and duration of treatment 
exposure to SM will be presented for the safety population.  The number and percentage 
of subjects maintained on the target dose versus those reduced in dose during the 
Maintenance Period will be provided. 
Analysis of treatment compliance and exposure will be performed separately for the 
Baseline and Randomization Period, Dose Treatment Period, and combined Baseline 
and Randomization and Dose Treatment Periods.  
9.7.1.1.3. Concomitant Medications 
Concomitant medications will be assigned an 11-digit code using the WHO Drug 
Dictionary (WHO DD) drug codes.  Concomitant medications will be further coded to the 
appropriate Anatomical-Therapeutic-Chemical (ATC) code indicating therapeutic 
classification.  A tabular summary of concomitant medications by drug class will be 
presented for the safety population. 
9.7.1.2. 
Efficacy Analyses 
Efficacy analyses will be conducted for the ITT population.  Where appropriate, a 
restricted ITT population may also be used.   
Descriptive statistics will be presented for all efficacy variables by visit and treatment 
group.  
All significance tests will be performed at the 0.05 level. 
9.7.1.2.1. Primary Efficacy Analysis 
The primary efficacy measure is the investigator-rated CAARS Total ADHD Symptom 
Score which is the sum of the Inattention and Hyperactivity/Impulsivity subscales (18 
items measured on 4-point scale: 0, 1, 2, and 3). 
The changes from baseline to the endpoint (visit 8) in the investigator-rated CAARS 
Total ADHD Symptom Scores will be compared between the two treatment groups using 
the Wilcoxon rank-sum test or the two-sample t-test.   
To confirm the results (sensitivity analysis), a mixed model repeated measures (MMRM) 
analysis will be conducted.  MMRM analysis will contain fixed effect terms for treatment,

investigative site, visit, and interaction between treatment and visit.  The model will 
include post-baseline values of the investigator-rated CAARS Total ADHD Symptom 
Score as the dependent variable with a random patient effect and baseline investigator-
rated CAARS Total ADHD Symptom Score as a covariate and will use an unstructured 
covariance. 
9.7.1.2.2. Secondary Efficacy Analyses 
The following secondary efficacy analyses will be performed: 
1. Initial efficacy of SPN-812V starting dose (150 mg/day) when compared to 
placebo as measured by changes in the investigator-rated CAARS Total ADHD 
Symptom Score from baseline at week 1 of treatment with starting dose will be 
analyzed with Wilcoxon rank-sum test or two-sample t-test 
2. Effectiveness of any SPN-812V dose when compared to placebo as determined 
by the weekly changes in the Clinical Global Impression – Improvement (CGI-I) 
score from baseline severity for 6-week treatment will be plotted as mean CGI-I 
change versus visit and analyzed using Wilcoxon rank-sum test or two-sample t-
test 
3. Clinical utility of SPN-812V study dose (300 mg/day) when compared to placebo 
as determined by the investigator’s assessment of the changes in the Conner’s 
Adult ADHD Rating Scale (CAARS) score from baseline at week 2, 3, 4, 5, and 6 
of treatment will be analyzed with Wilcoxon rank-sum test or two-sample t-test 
4. Study subject’s perception of clinical benefit of SPN-812V study dose (300 
mg/day) when compared to placebo as determined by changes in the self-rated 
Conner’s Adult ADHD Rating Scale (CAARS) score from baseline at endpoint 
after 5-week treatment will be analyzed with Wilcoxon rank-sum test or two-
sample t-test 
9.7.1.2.3. Subgroup Analyses for Efficacy 
Subgroup analyses for efficacy will be performed on categories of the following 
measures: 
• 
Sex 
• 
Race 
for the ITT population for the investigator-rated CAARS Total ADHD Symptom Score.  
Subgroup analyses will also be carried out for the following subscales 
• 
investigator-rated CAARS inattention subscale score 
• 
investigator-rated CAARS hyperactivity/impulsivity subscale score 
 
that together make up the CAARS Total ADHD Symptom Score 
9.7.1.3. 
Pharmacokinetic Analyses 
Population PK data will be pooled across all subjects and analyzed using nonlinear 
mixed-effects modeling methods.  The objective of the population PK analyses is to 
derive individual-specific estimates of apparent oral clearance (CL/F) but not to fully 
characterize the PK of this formulation of viloxazine.

9.7.1.4. 
Safety Analyses 
Evaluation of safety will be performed for the safety population.  Safety data that will be 
evaluated include AEs, clinical laboratory results, vital signs, ECGs, and physical 
examination findings.  
9.7.1.4.1. Adverse Events 
AEs will be classified into standardized medical terminology from the verbatim 
description (Investigator term) using the Medical Dictionary for Regulatory Activities 
(MedDRA).  AEs will be presented in the summary tables by preferred term nested 
within System Organ Class (SOC).  Verbatim description and all MedDRA level terms, 
including the lower level terms, for all AEs will be contained in the subject data listings.   
Data for AEs will be analyzed using the treatment-emergent signs and symptoms 
(TESS) philosophy.  TESS are defined as AEs that: 
• 
emerge during treatment, having been absent at pretreatment, or  
• 
reemerge during treatment, having been present at pretreatment but stopped prior to 
treatment, or  
• 
worsen in severity during treatment relative to the pretreatment state, when the AE is 
continuous. 
Only treatment-emergent AEs (TEAEs) from the study will be summarized in tables.  
TEAEs will be summarized by presenting, for each treatment group, the incidence of 
AEs.  The incidence of TEAEs will be based on the numbers and percentages of 
subjects with TEAEs.  Although a MedDRA term may be reported more than once for a 
subject, that subject will be counted only once in the incidence count for that MedDRA 
term. 
Separate TEAE incidence tables will be presented for the Baseline and Randomization 
Period, Dose Treatment Period, and combined Baseline and Randomization and Dose 
Treatment Periods.  For the combined Baseline and Randomization and Dose Treatment 
Periods, the incidence of TEAEs will also be presented by highest severity reported, 
closest relationship to SM reported, and the dose of SM at first occurrence.  For 
treatment-related TEAEs only, i.e., those TEAEs classified as possibly or definitely 
related to SM, the incidence rates will also be summarized as described previously for all 
TEAEs.  Listings (and tabular summaries, if warranted) of deaths, other SAEs, and other 
significant AEs, including AEs resulting in treatment discontinuation, will be provided. 
9.7.1.4.2. Laboratory Values 
By-visit tabular summaries of the laboratory test results will be presented.  For 
quantitative laboratory tests, both actual values and change from screening values will 
be summarized. 
Laboratory test results will be assigned an LNH classification according to whether the 
value was below (L), within (N), or above (H) the laboratory parameter’s reference 
ranges provided by the central laboratory.  Within treatment comparisons will be based

on 3 by 3 tables (shift tables) that, for a particular laboratory test, compare the LNH 
classification at screening to the LNH classification and the Final Visit. 
9.7.1.5. 
Vital Signs 
By-visit tabular summaries of the actual vital sign, height, and weight measurements and 
the changes from baseline will be presented. 
9.7.1.6. 
ECG Results 
By-visit tabular summaries of the quantitative ECG parameters and the overall ECG 
findings (normal, abnormal not clinically significant, or abnormal clinically significant) will 
be presented.  For the quantitative ECG parameters, both actual values and change 
from screening values will be summarized. 
9.7.1.7. 
Other Special Tests 
Findings from the physical examinations will be summarized through 2 by 2 shift tables 
that, for each system or area examined, compare the normal/abnormal finding at 
screening to the normal/abnormal finding at the Final Visit. 
9.7.2. Sample Size and Power Considerations 
Approximately 50 subjects (approximately 25 per treatment group) will be randomized in 
the study.  The sample size is not based on any statistical considerations, but it was 
judged adequate to provide safety, PK, and efficacy information for a proof-of-concept 
study.     
10.  PROCEDURES AND INSTRUCTIONS 
10.1.  Ethics and Good Clinical Practice 
The Investigator agrees, when signing the protocol, to adhere to the instructions and 
procedures described in the protocol and to adhere to the principles of ICH GCP to 
which the protocol conforms as well as all governing local regulations and principles for 
medical research. 
The protocol, informed consent, and appropriate related documents must be reviewed 
and approved by an IRB constituted and functioning in accordance with ICH E6, Section 
3, and any local regulations, i.e. Federal Regulations, Title 21 CFR Part 56.  
Documentation of IRB compliance with the ICH and any local regulations regarding 
constitution and review conduct will be provided to the Sponsor. 
A signed letter of study approval from the IRB Chairman must be sent to the Investigator 
with a copy to the Sponsor prior to study start and the release of any SM to the site by 
the Sponsor (or designee).  If the IRB decides to suspend or terminate the study, the 
Investigator will immediately send the notice of study suspension or termination by the 
IRB to the Sponsor.

______________________________________________________________________ 
 
Study progress is to be reported to IRB annually (or as required) by the Investigator or 
Sponsor, depending on local regulatory obligations.  If the Investigator is required to 
report to the IRB, he/she will forward a copy to the Sponsor at the time of each periodic 
report.  SAEs should be reported to the IRB in accord with local regulatory requirements. 
10.2.  Subject Information and Informed Consent 
As part of administering the informed consent documents, the Investigator (or designee) 
must explain to each subject the nature of the study, its purpose, the procedures 
involved, the expected duration, the potential risks and benefits involved, and any 
potential discomfort.  Each subject must be informed that participation in the study is 
voluntary and that he/she may withdraw from the study at any time and that withdrawal 
of consent will not affect his/her subsequent medical treatment or relationship with the 
treating physician.   
This informed consent should be given by means of a standard written statement, written 
in non-technical language.  The subject should understand the statement before signing 
and dating it and will be given a copy of the signed document.  If written consent is not 
possible, oral consent may be obtained if witnessed by at least one person not involved 
in the study.  The verbal consent will be documented and signed by the Investigator and 
the witness(s).  No subject can enter the study before his/her informed consent has been 
obtained.   
A separate ICF will be given for the optional PK substudy.  The above procedures will be 
followed in obtaining this consent. 
10.3.  Changes to the Protocol 
There are to be no changes to the protocol without written approval from the Sponsor.  
The protocol will be followed as written. 
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 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 an immediate change to the protocol is felt by the Investigator to 
be necessary for safety reasons, the Medical Monitor must be notified promptly and the 
IRB for the site must be informed promptly. 
Changes affecting only administrative aspects of the study do not require formal protocol 
amendments or IRB approval, but the IRB must be kept informed of such changes.  In 
these cases, the Sponsor will send a letter to the IRB detailing such changes.

10.4.  Adherence to the Protocol 
The Investigator will conduct the study in strict accordance with the protocol, which has 
been written to enable the Investigator’s compliance with ICH E6, Section 4, 
“Investigator Guideline for Good Clinical Practices”. 
There are to be no Investigator-initiated deviations from the protocol.  Any subject whose 
treatment deviates from the protocol or who is not qualified for study participation may 
be ineligible for analysis and may compromise the study.  On occasion, a subject whose 
medical condition does not exactly conform to the specifications of the protocol but who 
could potentially benefit from study participation may be considered for enrollment by the 
Sponsor if the Investigator first reviews the situation with the Medical Monitor.  In these 
cases, the potential subject’s participation will be discussed with the Sponsor personnel 
prior to having the subject sign the informed consent, and the exemption for study 
enrollment will be sent in writing to the investigational site by the Sponsor.  The 
investigational site will retain a copy of this document.  If the Investigator learns at any 
time after informed consent that a subject does not meet protocol specifications for study 
participation, he/she will call the Medical Monitor immediately. 
Subjects who have not signed an IRB approved ICF cannot receive SM. 
The Investigator and research team must comply with ICH E6 principles and all 
applicable local regulatory laws and regulations. 
10.5.  Retention of Records 
In accordance with applicable regulatory requirements, following closure of the study, 
the Investigator will maintain a copy of all site study records in a safe and secure 
location in the original format until at least 2 years after the last approval of a marketing 
application or at least 2 years have elapsed since the formal discontinuation of clinical 
development of the SM. 
Essential documents include: 
• 
Signed informed consent documents for all subjects 
• 
Subject identification code list, screening log (if applicable) and enrollment log 
• 
Record of all communications between the Investigator and the IRB 
• 
Copies of CRFs and of documentation of corrections for all subjects 
• 
SM accountability records 
• 
All other source documents (subject medical records, hospital records, laboratory 
records, etc.) 
• 
All other documents as listed in Section 8 of the ICH E6 Guideline for GCP (Essential 
Documents for the Conduct of a Clinical Trial) 
Normally, these records will be held in the Investigator’s archives.  If the Investigator is 
unable to meet this obligation, he or she must ask the sponsor for permission to make 
alternative arrangements.  Details of these arrangements should be documented.

10.6.  Auditing Procedures 
In addition to the routine monitoring procedures, the Sponsor’s Corporate Quality 
Assurance department may conduct audits of clinical research activities in accordance 
with the Sponsor’s SOPs to evaluate compliance with the principles of ICH GCP and all 
applicable local regulations.  A government regulatory authority may also wish to 
conduct an inspection (during the study or after its completion).  If an inspection is 
requested by a regulatory authority, the Investigator must inform the Sponsor 
immediately that this request has been made. 
10.7.  Publication of Results 
Any presentation or publication of data collected as a direct or indirect result of this trial 
will be considered as a joint publication by the Investigator(s) and the appropriate 
personnel at the Sponsor’s site.  Authorship will be determined by mutual agreement.  
The study is being conducted as part of a multicenter clinical trial.  As stipulated in the 
protocol, data from all such sites shall be pooled and analyzed.  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, at least ninety (90) days prior to 
submission for publication or presentation.  No publication or presentation with respect 
to the study shall be made until any Sponsor comments on the proposed publication or 
presentation have been addressed to the Sponsor’s satisfaction. 
The detailed obligations regarding the publication of any data, material results, or other 
information, generated or created in relation to the study shall be outlined in the 
agreement between each Investigator and the Sponsor (or designee). 
10.8.  Disclosure and Confidentiality 
The contents of this protocol and any amendments and results obtained during the 
course of this study will be kept confidential by the Investigator, the Investigator’s staff, 
and 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 utilized in any written work, including 
publications, without the written consent of Sponsor.  These obligations of confidentiality 
and non-use shall in no way diminish such obligations as set forth in the Confidentiality 
Agreement between the Sponsor and the Investigator. 
All persons assisting in the performance of this study must be bound by the obligations 
of confidentiality and non-use set forth in the Confidentiality Agreement between the 
Investigator and Sponsor (provided by the Sponsor). 
10.9.  Discontinuation of Study 
The Sponsor reserves the right to discontinue the study for medical or administrative 
reasons at any time.  Reimbursement for expenses covering subjects, laboratory tests, 
and other professional fees will be made.  The Investigator will refund the excess of 
payments made in advance.
