Name of Investigational Product: 
Cannabidiol Oral Solution 
Name of Active Ingredient: 
Cannabidiol 
Title of Study:  
A Phase 3 Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Assess the 
Efficacy, Safety, and Tolerability of Cannabidiol Oral Solution as Adjunctive Therapy with Vigabatrin 
as Initial Therapy in Patients with Infantile Spasms 
Study center(s): Approximately 40 sites in the US and ex-US. 
Phase of development: Phase 3 
Objectives: 
Primary 
• To evaluate the efficacy of Cannabidiol Oral Solution as adjunctive therapy with 
vigabatrin as initial therapy in treating patients with Infantile Spasms.  
Secondary 
• To evaluate the continued efficacy of Cannabidiol Oral Solution after the 14-day 
treatment with vigabatrin or vigabatrin plus Cannabidiol Oral Solution is complete. 
• To evaluate the safety and tolerability of Cannabidiol Oral Solution as adjunctive 
therapy with vigabatrin as initial therapy in treating patients with Infantile Spasms. 
Methodology: 
This is a Phase 3, double-blind, placebo-controlled, randomized, multicenter study to evaluate 
the efficacy, safety, and tolerability of Cannabidiol Oral Solution (CBD) as adjunctive therapy 
with vigabatrin as initial therapy, compared to vigabatrin alone in the treatment of infants 
newly diagnosed with Infantile Spasms (IS). Randomization will occur during Visit 2 to one 
of two treatment groups:  
• Treatment with vigabatrin plus  
o CBD 40 mg/kg/day, or 
o Matching CBD 40 mg/kg/day placebo

Approximately 190 patients in total will be enrolled into one of the two treatment arms; 130 
patients in the investigational product arm with 60 patients in the placebo arm. Patients will be 
dosed approximately every 12 hours with meals to help ensure consistent plasma levels are 
achieved and to reduce variability.  
Doses of CBD exceeding 40 mg/kg/day will not be examined in this study. In addition to the 
safety assessments required by the study protocol, the investigator will monitor patients 
throughout the study as recommended in the current approved product label for vigabatrin. 
Study participants will be newly diagnosed pediatric patients age 1 to 24 months (inclusive) 
experiencing infantile spasms who satisfy all inclusion/exclusion criteria. This study will be 
comprised of five periods: Screening, Initial Treatment, Extended Treatment, Taper, and 
Follow-up Periods, with a maximum duration of approximately 140 days.  
Screening Period:  
Each newly diagnosed patient with Infantile Spasms will complete a Screening Period and will 
have up to 14 days to enroll in the study.  
Patients will have a minimum of a 9-hour video-EEG that includes at least one full sleep-wake 
cycle during their Screening Visit to establish their baseline level of infantile spasms and 
hypsarrythmia and a 24-hour video-EEG at Visit 5 (Day 14) of the Initial Treatment Period to 
establish their final level of infantile spasms and hypsarrythmia. A blinded central reader, not 
involved in the study, will evaluate the video-EEGs and determine responder status.  Details 
of the video-EEG assessment will be provided in the video-EEG Charter. The treatment 
response categories are summarized in Table 1 below. In addition, a 9-hour video EEG will be 
conducted during the Extended Treatment Period to confirm parent/caregiver reports of 
relapse. If possible, a 9-hour video EEG will be conducted for patients who have continued 
into the Extended Treatment Period and decided to Early Withdraw. A video EEG is not 
required for patients who decide to withdraw during the Initial Treatment Period. 
Table 1: Video EEG Response Definitions

Initial Treatment Period 
• Day 1 (Visit 2): Patients will receive the initial titration dose of vigabatrin 
(50 mg/kg/day divided twice daily [BID]), and either CBD 20 mg/kg/day plus 
matching CBD 20 mg/kg/day placebo or CBD 40 mg/kg/day placebo, each drug 
administered BID for 3 days. 
• Day 4 (Visit 3): Patients will return to the study center to evaluate medical status 
(seizure diary, vital signs, and neurological exam), clinical laboratory assessments,

5 
concomitant medications, height/weight, and assess adverse events (AEs). For those 
patients who tolerate the initial dose, the dose for vigabatrin will be increased to 
100 mg/kg/day (BID), and either CBD 30 mg/kg/day and matching CBD 10 mg/kg/day 
placebo, or CBD 40 mg/kg/day placebo BID for 3 days.  
• Day 7 (Visit 4): Patients will return to the study center to evaluate medical status 
(seizure diary, vital signs, and neurological exam), clinical laboratory assessments, 
concomitant medications, height/weight, and assess AEs.  For those patients who 
tolerate the increased doses, the dose of vigabatrin will be increased to 150 mg/kg/day 
and CBD or CBD placebo to 40 mg/kg/day BID for the remaining 9 days. Vigabatrin, 
CBD, and matching placebo will be administered in a twice daily fashion at 12-hour 
intervals with meals. 
• As part of their standard of care, investigators will assess safety and tolerability of the 
treatment regimens throughout the study period. All subjects will continue treatment 
until confirmation from the central reader on the 24-hour video EEG and clinical 
laboratory results are received. 
Extended Treatment Period 
Following the Initial Treatment Period: 
• Complete Responders will continue receiving their assigned treatments of 
vigabatrin plus either CBD 40 mg/kg/day or matching placebo for 75 days, until 
Week 13 (Day 90) to monitor treatment response.  
• During the Extended Treatment Period, the investigator may reduce the dose of 
CBD or CBD placebo to 30 mg/kg/day for safety or tolerability. If the subjects 
cannot tolerate the 30 mg/kg/day, they will be discontinued from the study 
following the completion of the taper period. 
Partial Responders: 
Partial responders will be offered the opportunity to enroll in an open-label safety study that 
allows investigators to combine standard-of-care treatment with CBD. 
Taper Period 
Following the completion of the Initial Treatment Period (Visit 6), partial responders who do 
not enroll in the open-label safety study and non-responders will have vigabatrin and CBD or 
CBD placebo tapered as follows:  
• Vigabatrin taper: 150 mg/kg/day will be reduced to 100 mg/kg/day for 3 days, then 
the 100 mg/kg/day dose will be reduced to 50 mg/kg/day for 3 days, and then 
discontinued.  
• CBD or CBD Placebo taper: 40 mg/kg/day will be reduced to 30 mg/kg/day for 
three days, then 30 mg/kg/day will be reduced to 20 mg/kg/day for 3 days, and then 
discontinued.

6 
Complete Responders will be tapered off vigabatrin and CBD at the completion of the 
Extended Treatment Period, and all patients will be tapered off at any Early Withdrawal 
Visits, using the same schedules as described above.  
If the investigator decides to continue vigabatrin as a treatment for patients at the end of the 
study or early withdrawal, tapering of vigabatrin will be left to the discretion of the PI. 
CBD requires tapering off at the End of Study or at the Early Withdrawal visit. 
Follow-up Period 
A follow-up phone call will occur for all subjects 30 days after discontinuation of the study 
drug to assess AEs, AETs, and record concomitant medications. 
Study Assessments 
To assess efficacy, a 24-hour video-EEG, daily seizure diaries, meal diary 24 hours prior to 
and through PK blood sampling and investigator Clinical Global Impressions-Global 
Improvement (CGI-I) assessments will be completed and evaluated.  
• A 9-hour video EEG that includes at least one sleep-wake cycle will be completed 
during Screening (Visit 1) and a 24-hour video EEG will be completed Day 14 (Visit 
5) through Day 15 (Visit 6). The EEGs and hypsarrythmia will be evaluated by a 
blinded central reader who is not involved with the study. Further details will be 
provided in the video-EEG Charter.   
• Daily seizure diaries will be completed throughout the Initial and Extended Treatment 
Periods. 
• The CGI-I will be completed by the investigator at Visit 6 of the Initial Treatment 
Period, or at Early Withdrawal. The CGI-S will be completed by the investigator at 
Screening. 
Safety assessments for all patients will include medical history, physical and neurological 
examinations, vital signs (seated or supine blood pressure [depending on patient age and 
ability], pulse rate, temperature, and respiration rate), clinical laboratory testing (hematology, 
chemistry, liver enzymes, and serum bilirubin), prior medication history (assessment of 
past/current AETs and concomitant medications), and AE assessments will be conducted at 
specific visits throughout the study. In addition to the safety assessments required by the study 
protocol, the investigator will monitor patients as recommended in the current FDA-approved 
vigabatrin prescribing information. 
A blood sample for PK analysis of CBD and the metabolite 7-hydoxy-CBD (7-OH-CBD) will 
be obtained on Day 15 prior to the second dose during the 24-hour video-EEG. A meal diary 
will be used to record the type of meals consumed in relation to PK blood draws. 
If a patient discontinues the study prematurely, the investigator’s impression of efficacy and 
tolerability of the study drug, as evaluated by CGI-I, will be assessed and recorded 
immediately before discontinuation. If possible, the parent/caregiver will be encouraged to 
have the patient have an Early Withdrawal video-EEG completed.

Statistical methods: 
Sample Size Calculation 
A total of 190 patients (130 and 60 patients in the two groups) will provide 80% power with a 
two-sided alpha of 0.05 to detect a difference in response rate, assuming the response with 
vigabatrin alone is 40% and the response with vigabatrin with Cannabidiol Oral Solution is 
60%. 
Analysis Populations 
Statistical analyses will be conducted on the following populations: 
• Safety Population: The Safety Population will include all patients who were treated 
with at least one dose of the study drug. 
• Intent to Treat (ITT) Population: The ITT Population will include all patients who 
were randomized.    
• PK Population: The PK Population will include all patients who were treated with at 
least one dose of the study drug and have at least one usable PK measurement. 
Efficacy Analyses 
The ITT Population will be used for all efficacy analyses in the Initial Treatment Period. 
• For the primary endpoint, a 2-sided Type I error rate of 0.05 will be used.   
• For the secondary efficacy endpoints, to maintain the trial-wise Type I error rate at 
0.05, a fixed sequence multiple comparisons correction with fallback will be used. The 
assignment of alpha levels to hypotheses being tested will be specified in the Statistical 
Analysis Plan. 
• For endpoints that are continuous in nature, the number of observations, mean, median, 
minimum and maximum, and standard deviation (SD) values will be presented as 
descriptive statistics. For inferential statistics, a t-test will be used to compare 
treatment to placebo group.  
• For endpoints that are categorical in nature, frequency, counts, and percentages will be 
presented as descriptive statistics, and a chi-square test will be used for inferential 
statistics. 
Primary Efficacy Analysis 
• Percent of patients with complete resolution of both infantile spasms and 
hypsarrhythmia at Day 15 (complete response) will be compared between vigabatrin 
plus placebo and vigabatrin plus CBD 40 mg/kg/day groups using a chi-square test.     
Secondary Efficacy Analyses 
• Percent of patients who relapse during the Extended Treatment Period will be 
compared between 14-day complete responders receiving vigabatrin + CBD and 
complete responders receiving 14-day vigabatrin + placebo using chi-square test. Time 
to relapse will be described with Kaplan-Meier curves and treatment groups compared 
using a log-rank test.

• Percent of patients with complete resolution of infantile spasms at Day 15 will be 
compared between treatment groups using a chi-square test. 
• Percent of patients with complete resolution of hypsarrhythmia at Day 15 will be 
compared between treatment groups using a chi-square test. 
• Investigator impression of efficacy and tolerability of study drug (Clinical Global 
Impression – Global Improvement [CGI-I]) will be compared between treatment 
groups using ANCOVA with baseline CGI-S as a covariate.  
• Reduction in percentage of spasm-free days between the Initial Treatment Period and 
Screening Period will be compared between treatment groups using ANCOVA with 
the Screening Period percent spasm-free days as a covariate.  
Secondary Efficacy Analyses for patients with a complete response during the Initial 
Treatment Period who continue to the Extended Treatment Period: 
• Percent of patients who relapse during the Extended Treatment Period confirmed by 
video-EEG following parent report of relapse.  
• Time to relapse. 
Safety Analyses 
The Safety Population will be used for all safety assessments. All safety assessments will be 
descriptive and no inferential statistics are planned for safety assessments. All data listings 
will be provided for protocol specified safety data.  
• The Medical Dictionary for Regulatory Activities (MedDRA; Version 20.0 or higher) 
will be used to classify all adverse events with respect to system organ class and 
preferred term. Adverse event summaries will include only TEAEs by treatment group.  
• Clinical laboratory findings will be summarized for all patients in the safety population 
for observed values and change from baseline. Shifts from baseline to outside normal 
range criteria will also be presented for all patients in the safety population. 
• Vital signs will be summarized for all patients in the safety population for observed 
values and change from baseline as appropriate. 
• The neurological examination results will be listed and summarized descriptively. 
Shifts from baseline according to normal and abnormal criteria will also be presented 
for all patients in the safety population. 
• Results of physical examinations conducted throughout the study will be presented in 
listings and summarized descriptively. Shifts from baseline according to normal and 
abnormal criteria will also be presented for all patients in the safety population. 
• Prior medication and concomitant medications will be reported in the data listings. 
• Statistical analyses will be performed using SAS® (Version 9.3 or higher, SAS 
Institute Inc.) or R (Version 3.3 or higher, Roswell Park Cancer Institute). 
Pharmacokinetic Analyses 
Exploratory analyses of dose (exposure)-response relationship will be performed.  Further 
population PK approach may be used for PK parameter calculations, as appropriate.

Missing Data 
There will be no imputation of the missing values. Patients without a video EEG assessment 
on Days 14-15 will be considered non-responders for all EEG-related endpoints. Percentage of 
spasm-free days will be calculated based on the number of entries (up to 15 days per 
measurement period). A sensitivity analysis may be conducted to assess the impact of the 
missing values on the final analysis.  The sensitivity analyses will be detailed in the SAP.

a Patients will be admitted to the study center as an inpatient on Day 14 and discharged on Day 15 following the completion of End of Study assessments. 
b End of Study assessments will be completed at Day 15 for partial and non-responder patients and Week 13 for patients who complete the extension period of 
the study. 
c Patients will have a minimum of a 9-hour video EEG that includes at least one full sleep-wake cycle during their Screening Visit and a 24-hour video EEG at 
Visit 5 (Day 14 to Day 15) during the Initial Treatment Period. A minimum of 9-hour video-EEG will be performed during the Extended Treatment Period to

confirm parent/caregiver report of relapse or complete resolution or at Early Withdrawal for patients who have continued into the Extended Treatment Period. A 
Video EEG is not required for patients who decide to withdraw during the Initial Treatment Period 
d To assess preliminary efficacy, a seizure history will be collected at screening to record the approximate number of seizures in the last 28 days as reported by 
the parent/caregiver. 
e Vital signs will be taken after approximately 5 minutes seated or supine, depending on patient ability. On Day 1(Visit 2), vital signs should be taken predose and 
at 4 hours postdose. On all other days, the assessment will be completed predose.   
f A brief neurological examination will be performed, except for the Screening Visit, Visit 6, Visit 9 and Early Withdrawal which will be a complete neurological 
exam. On Day 4 (Visit 3), and Day 7 (Visit 4) a brief neurological examination will be performed predose and approximately 2 hours following administration of 
the morning dose of the investigational product.  Additional examinations may be performed at the discretion of the investigator.  
g On Day 1 (Visit 2), patients will receive the initial titration dose of vigabatrin (50 mg/kg/day divided twice daily [BID]), and either CBD 20 mg/kg/day plus 
matching CBD 20 mg/kg/day placebo or CBD 40 mg/kg/day placebo, each drug administered twice daily for three days. 
h For those patients who tolerate the initial dose, the dose for vigabatrin will be increased to 100 mg/kg/day [BID], and either CBD 30 mg/kg/day plus matching 
CBD 10 mg/kg/day, or CBD 40 mg/kg/day placebo for 3 days. On Day 7 (Visit 4) the dose of vigabatrin will be increased to 150 mg/kg/day and CBD to 
40 mg/kg/day for the remaining 9 days for subjects who tolerate the previous dose. 
i Complete Responders will continue receiving their assigned treatments of vigabatrin plus either CBD 40 mg/kg/day or matching placebo for 75 days, until 
Week 13 (Day 90) to monitor treatment response. During the extended treatment period the Investigator can only down titrate once to 30 mg/kg/day. 
j All subjects will be tapered off vigabatrin as follows: 150 mg/kg/day will be reduced to 100 mg/kg/day for 3 days then the 100 mg/kg/day will be reduced to 50 
mg/kg/day for 3 days and then discontinued. Similarly, all subjects will be tapered off CBD or CBD Placebo according to the following schedule: 40 mg/kg/day 
will be reduced to 30 mg/kg/day for 3 days, then 30 mg/kg/day will be reduced to 20 mg/kg/day for 3 days, then discontinued. Patients will receive a follow-up 
phone call 4 weeks after completing the tapering.  Drug reconciliation will be completed at the end of study. 
k A blood sample for PK analysis will be obtained on Day 15 prior to the second dose during the 24-hour video EEG.  
l A seizure diary will record daily spasms between Visit 1 and Visit 2. The daily spasm record will continue through the Initial Treatment and Extended 
Treatment Periods, and throughout the Taper period for patients enrolled in the Extended Treatment Period. 
m Patients who discontinue the study drug early should return for the Early Withdrawal Visit.  
n Meal diary must be collected 24 hours prior to and through PK blood sampling on Day 15 (Visit 6).

1. 
INTRODUCTION 
Data presented in Section 1.0 include overviews from the nonclinical and clinical published 
literature that reports on various other formulations of cannabidiol (CBD) (primarily plant-
based). Analogous studies have not been completed for Cannabidiol Oral Solution, the 
pharmaceutical grade synthetic CBD to be investigated in this study. 
Please see the Investigator’s Brochure (IB)1 for more information. 
1.1. 
Cannabidiol 
The main active constituent of cannabis, Δ9-tetrahydrocannabinol (Δ9-THC) is the principal 
psychoactive constituent of marijuana. Cannabidiol is the second most abundant cannabinoid and 
highly physiologically relevant, but is non-psychoactive. It has demonstrated a potential benefit 
in treating patients with treatment-resistant epilepsy.2,3,4,5    
Insys Development Company, Inc. (hereafter referred to as the Sponsor) has successfully 
manufactured a pharmaceutical grade, synthetic CBD drug substance. It is manufactured in their 
current Good Manufacturing Practices (cGMP) manufacturing facility. This facility is approved 
by the Drug Enforcement Administration (DEA) and has been inspected by the Food and Drug 
Administration (FDA). This active pharmaceutical ingredient is ≥99.5% pure6 and can be 
consistently produced without the concern for contaminant.  
1.1.1. 
Mechanism of Action 
The mode of action of CBD is not fully understood. The drug substance manifests a low affinity 
for endogenous cannabinoid receptors 1 (CB1) and 2 (CB2). Cannabidiol acts as an indirect 
antagonist of CB1 and inhibits several CB1 mediated ∆9-THC effects.7 It also stimulates the 
vanilloid receptor type 18 and modulates the µ- and δ-opioid receptors.9 It may also increase 
plasma ∆9-THC levels by inhibiting its hepatic microsomal metabolism by competitively binding 
proteins in the cytochrome P450 (CYP) oxidative system.10 Finally, CBD may modulate 
neuronal hyperexcitability through one or more of the following mechanisms: 
• Bidirectional regulation of calcium homeostasis via the mitochondrial 
sodium/calcium exchanger.11  
• Agonistic properties at 5-hydroxytryptamine 1a (5-HT1a) receptors.12 
• Enhancing endogenous adenosine levels in the central nervous system (CNS) by 
reducing adenosine re-uptake.13,14  
Recent studies have shown that CBD dose-dependently increased seizure threshold in wild-type 
mice, an effect that was markedly reduced in transient receptor potential vanilloid 1 (TRPV1) 
channel knockout mice15, and blocked the G protein-coupled receptor-55 (GPR-55) mediated 
increase of miniature excitatory postsynaptic currents (mEPSCs) frequency in CA1 pyramidal 
neurons in healthy and epileptic tissues.16  
1.1.2. 
Metabolism and Potential Drug Interactions 
The major biotransformation pathway for CBD is similar to that of other cannabinoids and 
mediated by hydroxylation by cytochrome P450 (CYP) proteins.17 Its interactions with human 
drug metabolizing enzymes (as a substrate, inhibitor, or inducer) were recently reviewed.18,19    

Insys Development Company, Inc.                                               Protocol Number INS011-16-082 
05 Jul 2018                                                    CONFIDENTIAL                                                               26  
Cannabidiol is metabolized primarily in the liver by cytochrome P450 3A4 (CYP3A4) and to a 
lesser extent by cytochrome P450 2C19 (CYP2C19). The effect of cannabidiol on primary fetal 
rat hepatocyte viability was investigated.20 In vitro, hepatocytes showed reduced cell viability, 
inhibited cell growth, and cytoplasmic alterations after 24 hours of exposure to cannabidiol at 
concentrations of 10-4 to 10-3 M. Markers of cell injury increased following treatment of 
cannabidiol at concentrations of 10-4 M (160% of control after 24 hours of exposure) and 
5 x 10-5 M (220% of control after 72 hours). These results correspond to other studies showing 
that cannabidiol is a potent inhibitor of hepatic drug metabolism.21,22,23 Specifically, cannabidiol 
inhibits CYP3A4, cytochrome P450 3A5 (CYP3A5), and cytochrome P450 1A1 (CYP1A1) in 
vitro.24,25,26 It also appears to inhibit cytochrome P450 2C9 (CYP2C9)27 and the transport protein 
p-glycoprotein.28,29  
Cannabidiol likely inhibits drug metabolism when one of its metabolites binds to hepatic 
microsomal CYP proteins.30,31,32,33 Hexobarbital is metabolized by CYP2C9 and the duration of 
sleep induced by hexobarbital may be used as a surrogate for drug metabolism. Using this 
outcome measure, it was shown that suppression of drug metabolism by cannabidiol diminished 
following repeated exposure to the drug substance in rodents.34   
Clinically, oral intake of cannabidiol (100 mg every 4 hours for 5 to 12 days) produced a 36% 
lower clearance and 35% lower volume of distribution of hexobarbital in healthy volunteers.35 
Notably, this study also showed that liver function tests (LFTs) remained normal before and 
during cannabidiol ingestion. Cannabidiol also inhibited barbiturate metabolism in humans to an 
extent substantially greater than that observed for ∆9-THC. Conversely, another study reported 
that oral dosing with cannabidiol (25 mg/kg) did not significantly affect the total clearance, 
volume of distribution, or terminal elimination t1⁄2 of ∆9-THC metabolites.36  
1.2. 
Nonclinical Experience  
1.2.1. 
Safety 
Nonclinical toxicological assessments of CBD conducted by Insys Development Company, Inc. 
thus far have concluded that 600 mg/kg/day exceeded the maximum tolerated dose in adult rats. 
Female rats generally appear to be more sensitive to the effects of CBD (in terms of toxicity) 
than similarly treated males. Because of the microscopic findings in the skin (follicular atrophy) 
noted in both genders at all CBD dose levels, a No Observed (Adverse) Effect Level (NOAEL) 
could not be determined for this study. The main GLP 6-month adult rat and 9-month 
cynomolgus monkey chronic toxicity studies with CBD in Medium Chain Triglycerides (MCT) 
are underway with few clinical signs being observed in either study.   
Observations from single- and repeat-dose toxicology studies in rats and non-human primates 
demonstrate that CBD-induced hypoactivity is transient and does not induce 
psychopharmacological effects37. In rats, inhalation exposure of up to 1.6 mg/kg/day of CBD 
(smoke) once daily for 14 days was associated with a transient dose-related hypoactivity (and 
prostration) and body weight gain was depressed38. The target organ for toxicity was the testes 
(impairment of spermatogenesis and sperm maturation).   
In monkeys, a single intravenous dose of CBD produced dose-related hypoactivity, sedation, and 
prostration.36 Tremors and convulsions occurred at >150 mg/kg and mortality at ≥225 mg/kg 
(associated with respiratory arrest and cardiac failure). Liver weights were increased and testes 

Insys Development Company, Inc.                                               Protocol Number INS011-16-082 
05 Jul 2018                                                    CONFIDENTIAL                                                               27  
`weights were decreased in the 200 mg/kg groups. Whether these effects on liver and testes were 
test-article related could not be conclusively determined due to the small sample size. There were 
no other meaningful treatment-related changes in clinical signs, body weight, core body 
temperature, or clinical or gross anatomic pathology.   
In a 90-day repeated-dose oral toxicity study in monkeys, CBD (30 to 300 mg/kg/day) did not 
result in mortality, clinical signs, or adversely affect physiological parameters, body weights or 
gains, food consumption, or ophthalmologic or electrocardiogram (ECG) evaluations.39 Lower 
heart rates were observed in treated males only during the first month. The only target organ 
identified was the testes.  Similar to the observations in rats, lower testes weights were associated 
with dose-related inhibition of spermatogenesis, which did not appear to be reversible within the 
30-day recovery period. The NOAEL in the monkey was determined to be <30 mg/kg/day (<360 
mg/m2/day based on body surface area). 
In rat fertility studies, CBD appears to affect testicular development38,40, and reduce fertility 
(reproductive capacity) of males but not females.41 There were no studies that assessed the 
potential for effects on embryofetal development. The effects of CBD on perinatal and postnatal 
development principally showed effects in the testes of developing male pups.  
It is unclear whether the observed testicular effects on spermatogenesis are reversible or not, as recovery 
periods have not been of sufficient duration to allow recovery of the seminiferous epithelium. 
1.2.2. 
Efficacy in Animal Models of Epilepsy 
Plant-derived cannabidiol shows antiepileptic,42 antipsychotic, anti-dystonic, anti-emetic, and 
anti-inflammatory properties in animal models.43 These models support exploring the use of 
cannabidiol for the treatment of epilepsy.    
As an example, the anticonvulsant activity of oral cannabidiol was investigated in adult rat 
model of seizures (induced by maximal electroshock or audiogenic sources).44 Cannabidiol was 
effective against maximal electroshock-induced seizures (median effective dose [ED50] = 18 
mg/kg), but only minimally effective against audiogenic-induced seizures (ED50 ≥75 mg/kg).  
The neurotoxicity median tolerated dose (TD50) was >100 mg/kg. Cannabidiol co-administered 
with different anti-seizure drugs (e.g., phenytoin or carbamazepine) increased or reduced their 
anticonvulsant activity, indicating that synergism or antagonism with cannabidiol was drug 
specific. 
1.3. 
Clinical Experience  
Clinical data described in the following sections were collected following administration of 
various extracts of cannabidiol as oral solutions or solid formulations. Early reports have 
indicated the cannabinoids, in particular CBD, may be efficacious in treating refractory 
epilepsy.45, 46, 47, 48 In separate Phase 3 studies with a plant-derived purified CBD (Epidiolex®, 
GW Pharmaceuticals), patients with Dravet Syndrome and Lennox-Gastaut Syndrome (LGS) 
treated with 20 mg/kg/day demonstrated a significant decrease in the median monthly seizure 
rate when compared to controls.

1.3.1. 
Pharmacokinetics 
In human subjects, the pharmacokinetics (PK) of tetrahydrocannabinol (THC) containing 
cannabinoids varies as a function of its route of administration.   
Pulmonary assimilation of inhaled cannabinoids provides a maximum plasma concentration 
(Cmax) within minutes.   
The PK parameters of cannabidiol were evaluated in a group of five cannabis smokers.42 A high 
plasma clearance (960 to 1560 mL/minute) was calculated. A terminal half-life (t½) was not 
reached at 72 hours, but the available data indicated t½ for cannabidiol of 27 to 35 hours (mean 
of 31 hours) after smoking.21 The distribution volume was estimated to be approximately 
30 L/kg. The mean t½ for cannabidiol is 24 or 31 hours, respectively, when administered 
intravenously (IV) or inhaled.49      
After oral administration of 0.6 mg/kg of cannabidiol in normal subjects, the plasma time 
concentration curves over 6 hours post dosing were similar to that after 0.3 mg/kg of THC.50   
Oral doses of cannabidiol (10 mg/kg/day) once daily for 6 weeks in patients with Huntington’s 
disease resulted in mean weekly plasma concentrations of 5.9 to 11.2 µg/L.51  The volume of 
distribution of cannabidiol was about 30 L/kg greater than for THC, and the plasma clearance 
was similar to that of THC, ranging from 58 to 94 L/hour (960 to 1560 mL/min). After an IV 
dose of 20 mg, the average t1⁄2 for cannabidiol was 24 hours (range of 18 to 33 hours).21,52    
Following oral ingestion, psychotropic effects of THC set in with a delay of 30 to 90 minutes, 
reach their maximum after 2 to 3 hours, depending on the dose and specific effect.   
Following doses of 10 mg cannabidiol in combination with 10.8 mg THC in an oral spray for 9 
consecutive days, mean peak plasma concentrations were 1.14 (0.86) ng/mL for cannabidiol and 
2.72 (1.47) ng/mL for THC. The median time to Cmax (tmax) was 1.27 (range of 0.75 to 2.52) 
hours for cannabidiol and 1.50 (0.75 to 2.50) hours for THC.53   
A Phase 1 clinical study examined the results of sublingual administration of 10 mg THC with 
that of 10 mg THC and 10 mg cannabidiol in cannabis-based medicinal extracts.54 Despite 
administration of equivalent amounts of THC and cannabidiol, lower plasma concentrations of 
cannabidiol were consistently observed. Mean Cmax concentrations for THC, cannabidiol, and 
11-hydroxy (OH)-THC were 4.9, 3.3, and 4.5 ng/mL when 10 mg THC and 10 mg cannabidiol 
were administered. The tmax was approximately 4 hours for all three analytes.   
The systemic availability of cannabidiol administered via the smoking route averages 
approximately 31% with inter-patient variability ranging from 11% to 45%.21 The bioavailability 
of cannabidiol following oral administration is approximately 6%.46 
1.3.2. 
Overview of Safety 
Clinical studies in various human populations indicate that CBD has a favorable side-effect 
profile. Doses as high as 1500 mg are well tolerated.55 No significant reactions or serious adverse 
events (SAEs) have been reported across a wide range of dosages in both acute and chronic 
settings. Bergamaschi et al.19 recently reviewed the safety of CBD in humans examined in 221 
patients across 21 studies. As detailed in the IB1, no significant safety issues were reported. 
Regarding doses of CBD that have been examined in other studies, daily doses of 200 to 300 mg 
CBD (or potentially more) may be safe.2,56 Clinical evaluation and therapeutic ranges of CBD

doses have been reported to be between 10 and 1500 mg/day, with the majority of reports 
evaluating doses in the 300 to 600 mg/day CBD range. Further, between 300 and 1500 mg have 
been used in humans without toxicity or SAEs.45,57,58,59    
1.3.3. 
Selected Clinical Safety Data  
Insys study INS011-14-029 enrolled 62 patients with refractory seizures between 1 and 17 years 
of age. Cannabidiol Oral Solution, 300 mg/mL at doses between 10 mg/kg/day and 40 mg/kg/day 
were generally well tolerated and no patient discontinued. Fifty-two of the 61 patients enrolled 
into a long-term safety study (INS011-14-030). Study INS011-14-030 was a long-term, open-
label, 48-week study for pediatric patients aged 1 year to 17 years with refractory epilepsy who 
participated in the Phase 1/2 Study INS011-14-029.  
Insys recently completed a long-term safety study (INS011-14-030) in pediatric patients with 
refractory epilepsy who participated in the Phase 1/2 PK study (INS011-14-029). This study was 
a long-term, open-label, 48-week study for pediatric subjects aged 1 year to 17 years with 
refractory epilepsy who participated in the Phase 1/2 Study INS011-14-029. A total of 52 
subjects (9 infants, 26 children, and 17 adolescents) were enrolled and received at least one dose 
of the investigational product in this study. Forty-five (86.5%) subjects completed the study 
including follow-up. Seven (13.5%) subjects prematurely discontinued treatment and study 
participation: 2 (3.8%) subjects due to AEs, 3 (5.8%) subjects due to withdrawal of consent, 
1 (1.9%) subject due to death considered not related to investigational product, and 1 (1.9%) 
subject due to other reason (reported lack of efficacy).   
The mean modal dose (defined as the dose with the longest duration) was 24.42 mg/kg/day and 
the mean total duration of study drug was 311.1 days. Overall, 13 subjects (14.4%) had dose 
reductions during the study: 12 subjects (13.3%) had dose reductions due to an AE and 1 subject 
(1.1%) had a dose reduction due to “other” reason. The incidence of dose reductions resulting 
from an AE was higher for subjects who received 40 mg/kg/day (8 subjects, 30.8%) compared 
with subjects who received 20-<30 mg/kg/day (6 subjects, 8.8%) and 30-<40 mg/kg/day (1 
subject, 6.6%). No subjects who received 10-<20 mg/kg/day and no infants had dose reductions. 
The trend was to increase the doses over the course of the study. There were 39 subjects (43.3%) 
who had dose increases during the study. The incidence of dose increases was higher for subjects 
who received 10-<20 mg/kg/day (14 subjects, 100%) compared with subjects who received 20-
<30 mg/kg/day (16 subjects, 47.1%) and 30-<40 mg/kg/day (9 subjects, 56.3%).   
Overall, 47 subjects (90.4%) experienced ≥1 adverse event (AE) during the study. The following 
AEs were reported in at least five subjects during the study:  seizure (16 subjects, 30.8%), upper 
respiratory tract infection (eight subjects, 15.4%), anemia (seven subjects, 13.5%), diarrhea 
(seven subjects, 13.5%), pyrexia (seven subjects, 13.5%), somnolence (seven subjects, 13.5%), 
aggression (five subjects, 9.6%), nasopharyngitis (five subjects, 9.6%), and otitis media (five 
subjects, 9.6%). There were 47 AEs reported for 24 (46.2%) subjects that were considered 
possibly or probably related to the investigational product. The most common possibly or 
probably related AEs reported were anemia (five subjects, 9.6%), somnolence (four subjects, 
7.7%), and weight increased (four subjects, 7.7%). One subject died during the study; the death 
resulted from an SAE of systemic sepsis leading to multi-organ failure and was considered not 
related. Relevant medical history included sodium voltage-gated channel alpha subunit 8 
mutation, patent foramen ovale, tracheomalacia, tracheostomy, gastrostomy, gastroesophageal 

Insys Development Company, Inc.                                               Protocol Number INS011-16-082

reflux disease, global developmental delay, cortical visual impairment, and hypotonia. Overall, 
17 (32.7%) subjects had experienced a total of 37 serious TEAEs. The most frequently reported 
serious TEAEs were seizure (six subjects, 11.5%), status epilepticus (two subjects, 3.8%), and 
mental status changes (two subjects, 3.8%).     
An open-label study of Cannabidiol Oral Solution, 300 mg/mL (20 mg/kg/day and 40 
mg/kg/day) in pediatric patients with infantile spasms refractory to adrenocorticotropic hormone 
(ACTH) and vigabatrin recently was halted due to futility (Protocol INS011-15-054). However, 
the drug was generally well tolerated for doses up to 40 mg/kg/day. A total of nine patients were 
included in the safety analysis. The mean duration of exposure was 29.6 days (min, max: 5, 159). 
Eight patients were treated for approximately 2 weeks at 20 mg/kg/day while the patient who 
was a Complete Responder received 238 days of investigational (IP). She increased her dose to 
40 mg/kg/day at Week 10 and continued that dose until Week 34 when she enrolled into the 
long-term safety study INS011-14-030 to continue treatment. Of the nine patients in the safety 
population, three (33%) had four events: infantile spasms (3) and sedation (1).  
Insys study INS011-15-043 enrolled 24 healthy adults who received a single dose of 20 mg/kg 
Cannabidiol Oral Solution, 300 mg/mL as part of a food effect study (Treatment A= fasted, 
Treatment B= fed). Neutropenia was reported in two subjects [one fed (moderate) and one 
fasting (mild)]. Other AEs (all considered mild) reported in the fasting arm included diarrhea (1), 
dry mouth (1) and nausea (1) and events of diarrhea (2) and flatulence (1) were reported in 
patients in the fed arm. All diarrhea, dry mouth, flatulence, and nausea events were considered 
possibly related to study drug.  No serious AEs or deaths were reported. 
INS011-16-093 was a Phase 1, open-label, randomized, single-dose (10 mg/kg), four-treatment, 
four-sequence, four-period, four-way crossover food effect study of multiple formulations 
[sesame oil-based, 100 mg/mL (fed and fasted), MCT-based, 100 mg/mL (fed), and ethanol-
containing 80 mg/mL (fed)] of Cannabidiol Oral Solution in 8 healthy adult subjects.  No serious 
AEs or AEs that led to subject discontinuation were reported. A total of two AEs were reported 
during the study, both following 10 mg/kg Cannabidiol Oral Solution, 80 mg/mL, administered 
under fed conditions. Two subjects reported mild abdominal pain, and the Investigator judged 
each as possibly related to study treatment. Both AEs resolved in less than 1 day. No AEs were 
related to abnormal laboratory tests, vital signs, ECGs, or physical examinations. 
Safety data from the food effect studies in healthy adult subjects demonstrated that the MCT 
formulations single dose of 20 mg/kg [Cannabidiol Oral Solution, 300 mg/mL (INS011-15-043)] 
and 10 mg/kg/dose [Cannabidiol Oral Solution, 100 mg/mL (INS011-16-093)] was generally 
well tolerated. No AEs were reported for the MCT 100 mg/mL formulation in INS011-16-093) 
and only eight treatment-emergent AEs were reported in INS011-15-043 [three patients fasting 
and four subjects fed (diarrhea and neutropenia)]. The AE of neutropenia was considered not 
related. Although the CBD exposure was much higher in the fed state, there was no significant 
difference in the number of AEs reported between fed and fasted, indicating these higher 
exposures did not lead to higher rates of adverse events.   
The above safety data collected from five clinical studies demonstrate the CBD is generally well 
tolerated for doses up to 40 mg/kg/day and for durations for up to one year.

1.3.4. 
Efficacy in Human Epilepsy 
Several preliminary studies of CBD report reductions in seizure activity for a significant subset 
of subjects.    
In a recent report, 10 pediatric subjects (3 to 12 years of age) and one adult subject (22 years of 
age) showed reductions in motor seizures (generalized tonic-clonic, tonic, myoclonic, atonic) per 
week. Eight (73%) subjects reported a 95-100% reduction in seizure occurrence, 1 (9%) reported 
75% reduction and 2 (18%) reported 20-45% reductions.60 
In an expanded-access program in 137 patients treated with Epidiolex® (an oil-based CBD 
extract) in the efficacy population, they reported a median reduction in monthly motor seizures 
of 36.5% after 12 weeks of treatment compared to baseline.61 
In a Phase 3 study, 120 patients with Dravet Syndrome were randomized into two treatment 
arms, Epidiolex® 20 mg/kg/day (n=61) and placebo (n=59). Epidiolex® or placebo was added to 
current anti-epileptic drug (AED) treatment regimens62 (GW Pharmaceuticals, Dravet Syndrome 
study). On average, patients were taking approximately 3 AEDs, having previously tried and 
failed an average of more than 4 other AEDs. The average age of trial participants was 10 years 
and 30 percent of patients were less than 6 years of age. The median baseline convulsive seizure 
frequency per month was 13. 
The primary efficacy endpoint was a comparison between Epidiolex® and placebo measuring the 
percentage change in the monthly frequency of convulsive seizures during the 14-week treatment 
period compared with the 4-week baseline observation period. In this study, patients taking 
Epidiolex® achieved a significant median reduction in monthly convulsive seizures of 39 percent 
compared with a reduction on placebo of 13 percent (p=0.01). The difference between 
Epidiolex® and placebo emerged during the first month of treatment and was sustained during 
the entire treatment period. 
1.4. 
Infantile Spasms 
Infantile Spasms is a devastating form of epilepsy that typically strikes children in the first year 
of life.62 Usually provoked by one of many structural, genetic, or metabolic etiologies, Infantile 
Spasms manifests with clusters of a distinct seizure-type (spasms), and is often accompanied by 
an EEG pattern known as hypsarrhythmia.63 Unsuccessful treatment, as well as delay in 
definitive treatment, are associated with tremendous reductions in neurodevelopmental 
outcome.64 Among pharmacologic therapies for infantile spasms, hormonal therapies such as 
intramuscular adrenocorticotropic hormone (ACTH, Acthar®)65,66,67 and vigabatrin (Sabril®)68 
are the most efficacious. Almost half of patients either fail first line therapy or relapse after 
initially successful treatment.69 The side-effect profiles of the above therapies are poor: 
vigabatrin is associated with irreversible peripheral visual field defects70,71 and the hormonal 
therapies impart substantial risk of immunosuppression leading to potentially lethal bacterial 
infections (pneumonia, sepsis, meningitis, etc.) as well as hypertension that has been associated 
with cardiac failure. 
Accordingly, there is a tremendous need for safe and effective therapies in the treatment of 
infantile spasms. This need is even more pronounced in those patients who have failed currently 
approved therapies.

1.5. 
Study Rationale 
Therapeutic failure may lead epilepsy patients to try alternative treatments, including 
“recreational drugs” and especially cannabis.72 As summarized in Sections 1.2.1 and 1.3.2, 
nonclinical and clinical data show that cannabidiol has a largely favorable safety profile.  
However, carefully controlled efficacy and safety studies have not been done and the specific 
profile of Cannabidiol Oral Solution has not been examined in infantile spasms.    
The primary purpose of this study is to formally investigate the efficacy and safety of 
Cannabidiol Oral Solution as adjunctive therapy in first-line treatment with vigabatrin to 
determine whether the addition of CBD will either increase the response rate associated with the 
use of vigabatrin alone or reduce the incidence of relapse.   
1.6. 
Summary of Potential Risks and Benefits 
As discussed in Sections 1.2 and 1.3, numerous nonclinical and clinical studies have examined 
other formulations of CBD. Several areas of potential concern have been identified with the use 
of CBD, especially in nonclinical studies. These include:   
• Competitive binding of CYP proteins (thus, an impact on drug metabolism in the 
liver).  
o Cannabidiol is metabolized predominantly by CYP3A4 and CYP 2C19.  
Cannabidiol may inhibit these two isozymes, as well as having small effects on 
CYP3A5, CYP1A1, and CYP2C9. 
• Abnormal spermatogenesis. 
• Abnormal induction of FSH in males. 
• Potential downregulation of immune responses involving the T, B, T-helper, and T 
cytotoxic subsets of leukocytes and/or those dependent on IL-2 or IFN-γ. 
Based on recent studies of cannabinoid administration in humans, controlled CBD may be safe in 
humans and animals. However, further studies are needed to clarify these reported in vitro and in 
vivo side-effects.20  
A Phase 1/2 study to assess the pharmacokinetics and safety of multiple doses of pharmaceutical-
grade synthetic Cannabidiol Oral Solution in 61 pediatric subjects with treatment-resistant 
seizure disorders who were between <2 years of age to 17 years of age was conducted by Insys 
(Protocol INS-011-14-029). Steady-state levels of cannabidiol appeared to be attained with 
approximately 2 to 6 days of repeated BID dosing with Cannabidiol Oral Solution, with 
geometric mean AUC (0-tau) of 507.0 (Cohort 1 [10 mg/kg/day,]) 836.0 (Cohort 2 [20 
mg/kg/day]), and 2108 ng·h/mL (Cohort 3 [40 mg/kg/day]) for all age categories combined. All 
doses of Cannabidiol Oral Solution from 10 mg/kg/day up to 40 mg/kg/day in divided doses 
were generally well tolerated. There were no clinically relevant differences in the AE profile 
among patients in the infant, child, and adolescent age categories. The majority of patients 
reported ≥1 TEAE (most commonly in the system organ classes of gastrointestinal disorders and 
nervous system disorders). 

Insys Development Company, Inc.                                               Protocol Number INS011-16-082

The inclusion/exclusion criteria, concomitant medication guidelines, and safety monitoring (AEs, 
clinical laboratory, vital signs, and physical examination assessments) planned for this study are 
intended to minimize these potential safety risks.   
Criteria for removal of subjects from the study will dictate discontinuation of subject 
participation should a safety issue arise (see Section 3.3).  
Two facets of the current treatment landscape for pediatric patients with infantile spasms support 
the potential benefit for patients in this study. First, as reviewed in Section 1.4, newly diagnosed 
pediatric patients when treated with either ACTH or vigabatrin experience a significant unmet 
medical need despite ongoing treatment because of the limited response rate or the incidence of 
relapse. This study is expected to serve as a critical step in the development of Cannabidiol Oral 
Solution as an adjunctive treatment for pediatric patients who are initially diagnosed with 
infantile spasms.    
Second, pharmaceutical grade synthetic Cannabidiol Oral Solution is expected to have several 
distinct advantages over cannabis plant-derived extracts:  
• Availability of the drug substance does not depend on cannabis plant production.  
o As such, the development of Cannabidiol Oral Solution will not support growth 
and distribution of plants from which marijuana is derived.   
• Manufacture of Cannabidiol Oral Solution does not involve an extraction process 
whereby the derived constituents could also include a significant amount of Δ9-THC.    
o The manufacturing process can be controlled so that mass quantities can be 
produced that are uniform in quality, purity, and consistency and can be delivered 
in known and predetermined quantities. 
• Variability in concentration and constituents should be reduced among batches, which 
may improve safety and tolerability. 
• Reduced concern for contamination by Δ9-THC, herbicides, pesticides, etc.

INVESTIGATIONAL PLAN 
3.1. 
Overall Study Design 
This is a Phase 3, double-blind, placebo-controlled, randomized, multicenter study to evaluate 
the efficacy, safety, and tolerability of Cannabidiol Oral Solution (CBD) as adjunctive therapy 
with vigabatrin as initial therapy, compared to vigabatrin alone in the treatment of infants newly 
diagnosed with Infantile Spasms (IS). Randomization will occur during Visit 2 and then 
allocated to one of two treatment groups:  
• Treatment with vigabatrin plus  
• CBD 40 mg/kg/day, or 
• Matching CBD 40 mg/kg/day placebo 
Approximately, 190 patients in total will be enrolled into one of the two treatment arms; 130 
patients in the investigational product arm with 60 patients in the placebo arm. Patients will be 
dosed approximately every 12 hours with meals to help ensure consistent plasma levels are 
achieved and to reduce variability.  
Doses of CBD exceeding 40 mg/kg/day will not be examined in this study. In addition to the 
safety assessments required by the study protocol, the investigator will monitor patients 
throughout the study as recommended in the approved product label for vigabatrin. Study 
participants will be newly diagnosed pediatric patients age 1 to 24 months (inclusive) 
experiencing infantile spasms who satisfy all inclusion/exclusion criteria. This study will be 
comprised of five periods: Screening, Initial Treatment, Extended Treatment, Taper, and Follow-
up Periods, with a maximum duration of approximately 140 days.  
The study design and patient progression through the study is outlined in Figure 1. All screening, 
efficacy, and safety evaluations will be performed according to the schedule of assessments 
summarized in Table 1. 
Each newly diagnosed patient with Infantile Spasms will complete a Screening Period and will 
have up to 14 days to enroll in the study.  
Patients will have a, minimum of a 9-hour video EEG that includes at least one full sleep-wake 
cycle during their Screening Visit to establish their baseline level of infantile spasms and 
hypsarrythmia and a 24-hour video EEG at Visit 5 (Day 14 to Day 15 ) of the Initial Treatment 
Period to establish their final level of infantile spasms and hypsarrythmia. A blinded central 
reader, not involved in the study, will evaluate the video EEGs and determine responder status. 
Details of the video EEG assessment will be provided in the video-EEG Charter. The treatment 
response categories are summarized in Table 2. In addition, a 9-hour video EEG will be 
conducted during the Extended Treatment Period to confirm parent/caregiver report of relapse. If 
possible, a 9-hour video EEG will be conducted for patients who have continued into the 
Extended Treatment Period and decided to Early Withdraw. A video EEG is not required for 
patients who decide to withdraw during the Initial Treatment Period.

3.1.1. 
Initial Treatment Period 
• Day 1 (Visit 2): Patients will receive the initial titration dose of vigabatrin (50 
mg/kg/day divided twice daily [BID]), and either CBD 20 mg/kg/day plus matching 
CBD 20 mg/kg/day placebo or CBD 40 mg/kg/day placebo, each drug administered 
BID for 3 days. 
• Day 4 (Visit 3): Patients will return to the study center to evaluate medical status 
(seizure diary, vital signs, and neurological exam), clinical laboratory assessments, 
concomitant medications, height/weight, and assess adverse events (AEs). For those 
patients who tolerate the initial dose, the dose for vigabatrin will be increased to 100 
mg/kg/day BID, and either CBD 30 mg/kg/day and matching CBD placebo 10 
mg/kg/day, or matching CBD 40 mg/kg/day BID placebo for 3 days.  
• Day 7 (Visit 4): Patients will return to the study center to evaluate medical status 
(seizure diary, vital signs, and neurological exam), clinical laboratory assessments, 
concomitant medications, height/weight, and assess AEs.  For those patients who 
tolerate the increased doses, the dose of vigabatrin will be increased to 150 mg/kg/day 
and CBD or CBD placebo to 40 mg/kg/day for the remaining 9 days. Vigabatrin, 
CBD, and matching placebo will be administered in a twice daily fashion at 12-hour 
intervals with meals. 
As part of their standard of care, investigators will assess safety and tolerability of the treatment 
regimens throughout the study period. All subjects will continue on their treatment until 
confirmation from the central reader on the 24-hour video EEG and clinical laboratory results are 
received. 
3.1.2. 
Extended Treatment Period 
Following the Initial Treatment Period:  
• Complete Responders will continue receiving their assigned treatments of vigabatrin 
plus either CBD 40 mg/kg/day or placebo for 75 days, until Week 13 (Day 90), to 
monitor progress for treatment response.  
• During the Extended Treatment Period, the investigator may reduce the dose of CBD 
or CBD placebo to 30 mg/kg/day for safety or tolerability. If the subjects cannot 
tolerate the 30 mg/kg/day, the drug will be discontinued and the patient withdrawn 
from the study following the completion of the taper period.

3.1.3. 
Partial Responders 
• Partial responders will be offered the opportunity to enroll in an open-label safety 
study that allows investigators to combine standard-of-care treatment with CBD. 
3.1.4. 
Taper Period 
Following the completion of the Initial Treatment Period (Visit 6), partial responders who do not 
enroll in the open-label safety study and non-responders will have vigabatrin and CBD tapered as 
follows:  
• Vigabatrin taper: 150 mg/kg/day will be reduced to 100 mg/kg/day for 3 days, then 
the 100 mg/kg/day dose will be reduced to 50 mg/kg/day for 3 days, and then 
discontinued.  
• CBD or CBD Placebo taper: 40 mg/kg/day will be reduced to 30 mg/kg/day for three 
days, then 30 mg/kg/day will be reduced to 20 mg/kg/day for 3 days, and then 
discontinued.  
Complete Responders will be tapered off vigabatrin and CBD or CBD placebo at the completion 
of the Extended Treatment Period, and all patients will be tapered off at any Early Withdrawal 
Visits, using the same schedules as described above.  
If the investigator decides to continue vigabatrin as a treatment for patients after the end of study 
or early withdrawal, tapering of vigabatrin will be left to the discretion of the PI.  
CBD requires tapering off at the End of Study or at the Early Withdrawal visit. 
3.1.5. 
Follow-up Period 
A follow-up phone call will occur for all subjects 30 days after discontinuation of the study drug 
to assess AEs, AETs, and record concomitant medications.

such as albumin, direct bilirubin, total bilirubin, aspartate aminotransferase (AST), and 
alanine aminotransferase (ALT) ≥3 times the upper limit of normal (ULN). The 
investigator may deem the patient eligible if he or she judges the laboratory values to be 
not clinically significant.  
3.3. 
Removal of Patients from Therapy or Assessment 
Patients will be allowed to discontinue their participation in the study at any time for any reason 
(withdrawal of consent).  
The inclusion/exclusion criteria in Sections 3.2.1 and 3.2.2  are to be followed explicitly. If a 
patient who does not meet enrollment criteria is inadvertently enrolled, that patient should be 
withdrawn from the study and the Sponsor must be contacted.   
In addition, participation in this clinical study may be discontinued by the Investigator or by the 
sponsor for any of the following reasons: 
• Intolerable side effects of the study product. 
• Changes in medical status or medical condition of the patient such that the 
Investigator believes that patient safety will be compromised or that it would be in the 
best interest of the patient to stop treatment.  
• Patient safety or welfare is at risk. 
• Non-compliance with study visits, defined as failure to perform any portion of 
scheduled assessments or procedures. 
• Any unforeseen event that in the opinion of the treating physician and/or the Principal 
Investigator, will prevent the research participant from continuing in this study. 
• Sponsor decides to stop the study. 
In the event of a patient’s withdrawal, the investigator will promptly notify the sponsor. 
Patients who withdraw from the study early will complete an Early Withdrawal Visit. Should 
any patient choose to withdraw early from the study, they will be advised of the safety 
precautions to be taken and will be followed until resolution of any AE or until the unresolved 
AEs are judged by the investigator to have stabilized. 
If a patient discontinues the study prematurely, the investigator’s impression of efficacy and 
tolerability of the study drug, as evaluated by the Clinical Global Impression – Global 
Improvement (CGI-I) assessment, will be assessed and recorded immediately before 
discontinuation. If possible, the parent/caregiver will be encouraged to have an Early Withdrawal 
visit with 9-hour video-EEG. 
3.4. 
Dose Adjustment Criteria 
During the Extended Treatment Period, the investigator may reduce the dose of CBD or CBD 
placebo once from 40 mg/kg/day to 30 mg/kg/day for safety or tolerability. In addition, tapering 
of vigabatrin and CBD will be required as described in Section 3.1.4.

TREATMENTS 
4.1. 
Treatments Administered  
4.1.1. 
Initial Treatment Period 
On Day 1 (Visit 2), patients will receive the initial titration dose of vigabatrin (50 mg/kg/day 
divided twice daily [BID]), and either CBD 20 mg/kg/day plus matching CBD 20 mg/kg/day 
placebo or CBD 40 mg/kg/day placebo BID for 3 days. 
Following the 3-day titration, on Day 4 (Visit 3) vigabatrin will be increased to 100 mg/kg/day 
[BID], and either CBD 30 mg/kg/day and matching CBD placebo 10/mg/kg/day or matching 
CBD 40 mg/kg/day placebo BID for 3 days.  
On Day 7 (Visit 4) vigabatrin will be increased to 150 mg/kg/day plus CBD 40 mg/kg/day 
administered twice daily for the remaining 9 days. Placebo patients will receive CBD 
40 mg/kg/day placebo BID for 15 days. All subjects will continue on their treatment at the end of 
study until confirmation from the central reader on the 24-hour video EEG and clinical 
laboratory results are received. 
4.1.2. 
Extended Treatment Period 
Following the Initial Treatment Period:  
• Complete Responders will continue receiving their assigned treatments of vigabatrin 
plus either CBD 40 mg/kg/day or placebo for 75 days, until Week 13 (Day 90), to 
monitor progress for treatment response.  
• During the Extended Treatment Period, the investigator may reduce the dose of CBD 
or CBD placebo to 30 mg/kg/day for safety or tolerability. If the subjects cannot 
tolerate the 30 mg/kg/day, the drug will be discontinued and the patient withdrawn 
from the study following the completion of the Taper Period. 
4.1.3. 
Partial Responders 
• Partial responders will be offered the opportunity to enroll in an open-label safety 
study that allows investigators to combine standard-of-care treatment with CBD.  
4.1.4. 
Taper Period 
Following the completion of the Initial Treatment Period (Visit 6), partial responders who do not 
enroll in the open-label safety study and non-responders will have vigabatrin and CBD or CBD 
placebo tapered as follows:  
• Vigabatrin taper: 150 mg/kg/day will be reduced to 100 mg/kg/day for 3 days, then 
the 100 mg/kg/day dose will be reduced to 50 mg/kg/day for 3 days, and then 
discontinued.  
• CBD or CBD Placebo taper: 40 mg/kg/day will be reduced to 30 mg/kg/day for three 
days, then 30 mg/kg/day will be reduced to 20 mg/kg/day for 3 days, and then 
discontinued.

Complete Responders will be tapered off vigabatrin and CBD or CBD placebo at the completion 
of the Extended Treatment Period, and all patients will be tapered off at any Early Withdrawal 
Visits, using the same schedules as described above. If the investigator decides to continue 
vigabatrin as a treatment for patients at the end of study or early withdrawal, tapering of 
vigabatrin will be left to the discretion of the PI.  
CBD requires tapering off at the End of Study or at the Early Withdrawal visit. 
4.2. 
Method of Assigning Patients to Treatment Groups 
Following confirmation of eligibility, patients will be randomized into one of two investigational 
product dose groups (vigabatrin plus CBD 40 mg/kg/day or vigabatrin plus matching placebo).  
The randomization schedule will be computer generated by using a permuted block algorithm 
and will randomly allocate the IP to randomization numbers. The randomization numbers will be 
provided to the drug packager who will prepare blinded drug kits. The randomization schedule 
will be prepared by the sponsor or sponsor’s representative before the start of the study. No one 
involved in the study performance will have access to the randomization schedule before official 
unblinding of treatment assignment. No subject will be randomized into this study more than 
once. 
4.3. 
Blinding and Unblinding Treatment Assignment 
This is a double-blind study with vigabatrin, CBD, and matched CBD placebo components.  
Study centers will be provided with three dosage levels of CBD (20 mg/kg/day, 30 mg/kg/day, 
40 mg/kg/day, and matching placebos) in identical packaging, and three dosage levels of 
vigabatrin (50 mg/kg/day, 100 mg/kg/day, and 150 mg/kg/day), matched with the randomization 
schedule for that center. 
All patients and study personnel involved in the conduct of the study, including data 
management, will be blinded to the Initial Treatment Period. 
Study personnel will endeavor to safeguard the integrity of the study blind to minimize bias in 
the conduct of the study. Treatment unblinding is discouraged if knowledge of the treatment 
assignment will not materially change the planned management of a medical emergency.  
Unblinding will be permitted in a medical emergency that requires immediate knowledge of the 
patient’s treatment assignment. Unblinding should be discussed in advance with the sponsor, 
sponsor’s representative, or medical monitor if possible. For emergency unblinding, study 
personnel will contact the sponsor or sponsor’s representative. If the investigator is not able to 
discuss treatment unblinding in advance, then he or she must notify the sponsor, sponsor’s 
representative, or medical monitor as soon as possible about the unblinding incident without 
revealing the patient’s treatment assignment. The investigator or designee must record the date 
and reason for study unblinding in the source document for that patient. In all cases that are not 
emergencies, the investigator must discuss the event with the sponsor, sponsor’s representative, 
and/or medical monitor prior to unblinding the patient’s treatment assignment. 
If the treatment assignment is unblinded for an individual patient, study personnel will be 
notified of that patient’s treatment assignment without unblinding of the treatment assignments 
for the remaining patients in the study. Thus, the overall study blind will not be compromised. If 
a patient’s treatment assignment is unblinded, he or she may or may not be asked to withdraw 

Insys Development Company, Inc.                                               Protocol Number INS011-16-082

from the study. The investigator will make this decision after consultation with the sponsor, 
sponsor’s representative, or medical monitor. 
4.4. 
Dose Selection Rationale 
As described in Section 1.3.2, data suggest that doses up to 1500 mg/day of other formulations of 
cannabidiol may be safe. These dose levels were selected based on data regarding concentrations 
that have been administered with other cannabidiol products without significant safety concerns 
and accounting for the range of body weights of patients to be enrolled in this study. 
Additionally, doses up to 40 mg/kg/day were administered by the Sponsor in studies INS011-14-
029 and INS011-14-030 and were generally well tolerated. Three infants were dosed initially 
with 40 mg/kg/day in INS011-14-029 and continued on the same dose in INS011-14-030, which 
was a 48-week, long-term safety study. Two of four infants who received 20 mg/kg/day in 
INS011-14-029 titrated their dose from 20 mg/kg/day up to 40 mg/kg/day and continued 
receiving this dose throughout the long-term safety study. No infants had dose reductions in 
INS011-14-029, INS011-14-030, or INS011-15-054, the double refractory infantile spasms 
study. Thus, whether the dose was provided with or without titration, all infants generally 
tolerated the 40 mg/kg/day dose. Thus, these same doses will be administered in this study. 
4.5. 
Selection and Timing of Dose for Each Patient 
Patients will receive vigabatrin and CBD or CBD Placebo twice daily during the 15-day Initial 
Treatment Period as described in Section 4.1. Subsequently, Complete Responders will receive 
CBD or CBD Placebo and/or vigabatrin twice daily during the 75-day Extended Treatment 
Period.  
The date and time of all investigational product administrations will be documented in the case 
report form (CRF). 
4.6. 
Treatment Compliance 
The doses of vigabatrin and CBD or matching placebo will be administered at the study center 
on the days listed in Table 1 under the supervision of the investigator (or a designee). All other 
doses will be administered by a parent or caregiver. 
The Investigator, a member of the investigational staff, or a hospital pharmacist must maintain an 
adequate record of the receipt and distribution of all study medication using the Drug 
Accountability Form. These forms must be available for inspection at any time. 
All supplies of IP should be accounted for at the termination of the study and a written 
explanation provided for any discrepancies. All unused supplies and packaging materials are to 
be inventoried and returned by the Investigator to the Sponsor or a designee. The Investigator is 
not permitted to return or destroy unused clinical drug supplies or packaging materials unless 
authorized by the Sponsor or a designee. 
If the study is terminated, discontinued, suspended, or completed, all unused supplies of the 
investigational product will be returned to the Sponsor or a designee for destruction after the 
final drug accountability check has been performed. Sponsor approval is required prior to drug 
destruction. A certificate of destruction will be provided to the Sponsor.

All regulations issued by the DEA or per local regulations in ex-US locations concerning the 
accountability of Schedule I medications will be followed (e.g., prevention of diversion). 
4.7. 
Permitted and Prohibited Therapies 
4.7.1. 
Permitted Therapies 
Any medications (other than those excluded by the protocol, see Section 4.7.2) that the 
investigator considers necessary for a patient’s welfare and will not interfere with the 
investigational product may be given at the Investigator’s discretion. 
4.7.2. 
Prohibited Therapies 
During the Screening, Initial Treatment, Extended Treatment, Taper, and Follow-up Periods, 
patients are not to receive the following: 
• Any cannabinoids besides the investigational drug (other formulations of CBD, Δ9-
THC, hemp oil, Realm Oil or marijuana). Exclusion criterion number 4 prohibits use 
within 30 days of study entry. 
• Felbamate. 
• Valproic acid. 
• Clobazam. 
• Corticotrophins. 
• Medication(s) that are strong CYP3A4 inhibitors or inducers or CYP3A4-sensitive 
substrates with a narrow therapeutic index. A list of these medications is provided in 
Appendix 1. 
• Systemic steroid therapy (excluding inhaled medication for asthma treatment). 
• Any other investigational drug or investigational device.  
• Introduction of new anti-epileptic therapies (AETs) during the study is prohibited. 
Patients must refrain from consumption of grapefruit, grapefruit juice, Seville oranges, Seville 
orange marmalade, or other products containing grapefruit or Seville oranges within 3 days of 
the first administration of investigational product and throughout the entire Treatment and Taper 
Periods. 
Although they are not prohibited, patients taking concomitant medications may need to be 
monitored with special care to identify any AEs arising due to the potential for altered drug 
metabolism. This is discussed in detail in Section 6.2.6.9.

Cannabis and its constituents (including cannabidiol) are Schedule I controlled substances in the 
United States and subject to all applicable local and federal laws and regulations regarding these 
products. This includes security provisions for storing the controlled substances and for 
dispensing in a manner to prevent diversion. Additionally, the Sponsor or Investigator must 
provide a statement of the quantity to be manufactured and the sources of the chemicals to be 
used or the substance. 
For US sites, the DEA regulations detail specific security requirements for storage of the 
investigational product. For ex-US sites, local regulations must be adhered to and IP must be 
securely locked in a substantially constructed cabinet. Any loss in investigational product must 
be reported to the Sponsor. Licensed practitioners must store controlled substances in a “securely 
locked, substantially constructed cabinet” and must notify the DEA of the theft or significant loss 
of any controlled substances within 1 business day of discovering such loss or theft. 
Furthermore, all practitioners are prohibited from hiring employees who have been convicted of 
a drug-related felony or who have had a DEA registration denied or revoked. 
Investigators are responsible for ensuring that all applicable licensures are in place and storage 
conditions are appropriate.   
Study centers are required to provide complete information, including CRFs and final outcomes, 
on all instances of addiction, abuse, misuse, overdose, drug diversion/drug accountability, 
discrepancies in the amount of the clinical supplies of the investigational product, 
noncompliance, protocol violations, lack of efficacy, individuals lost to follow-up, and any other 
reasons why patients dropped out of the study. 
5.4. 
Drug Accountability 
The Investigator, a member of the investigational staff, or a hospital pharmacist must maintain an 
adequate record of the receipt and distribution of all study medication using the Drug 
Accountability Form. These forms must be available for inspection at any time. 
All supplies of IP should be accounted for at the termination of the study and a written 
explanation provided for discrepancies. All unused supplies and packaging materials are to be 
inventoried and returned to the Sponsor or a designee by the Investigator. The Investigator is not 
permitted to return or destroy unused clinical drug supplies or packaging materials unless 
authorized by the Sponsor or a designee. 
If the study is terminated, discontinued, suspended, or completed, all unused supplies of the 
investigational product will be returned to the Sponsor or a designee for destruction after the 
final drug accountability check has been performed. Sponsor approval is required prior to drug 
destruction. A certificate of destruction will be provided to the Sponsor. 
All regulations issued by the DEA concerning the accountability of Schedule I medications will 
be followed (e.g., prevention of diversion). Ex- US centers will be required to follow local 
regulations.

6. 
STUDY ASSESSMENTS  
6.1. 
Efficacy Assessments 
To assess the efficacy of Cannabidiol Oral Solution, a 9-hour video-EEG will be completed 
during Screening and a 24-hour video-EEG will be performed from Day 14 (Visit 5) to Day 15.  
During the Extended Treatment Period, a 9-hour video-EEG will be completed to confirm 
parent/caregiver reports of relapse or complete resolution. If possible, a 9-hour video EEG will 
be conducted for patients who have continued into the Extended Treatment Period and decided to 
Early Withdraw. A video EEG is not required for patients who decide to withdraw during the 
Initial Treatment Period. 
The video EEGs should include at least one full wake/sleep cycle. Video EEGs may be first read 
by the investigator. However, no efficacy assessment will be made based on the investigator’s 
reading of the video EEG and this read will not be captured in the database. An Independent 
Central Reader will evaluate all video EEGs in a blinded manner and determine responder status 
for the primary endpoint. Details regarding requirements for the conduction of the video EEG 
and the Independent Central Reader’s review and assessment of the video EEG is outlined in the 
EEG Charter. The treatment response categories are summarized in Table 2. 
• The CGI-S will be completed by the investigator at screening. 
• The CGI-I will be completed by the investigator at Visit 6 of the Initial Treatment Period, 
or the Early Withdrawal Visit. 
• Daily seizure diaries will be completed throughout the Initial and Extended Treatment 
Periods, or the Early Withdrawal Visit.  
If a patient discontinues the study prematurely, the investigator’s impression of efficacy and 
tolerability of the study drug, as evaluated by CGI-I, will be assessed and recorded immediately 
before discontinuation. If possible, the parent/caregiver will be encouraged to have the patient 
have an Early Withdrawal video-EEG completed. 
6.2. 
Safety Assessments 
Safety assessments for all patients will include medical history, physical and neurological 
examinations, vital signs (seated or supine blood pressure [depending on patient age and ability], 
seated blood pressure, pulse rate, temperature, and respiration rate), clinical laboratory testing 
(hematology, chemistry, liver enzymes, and serum bilirubin), prior medication history 
(assessment of past/current AETs and concomitant medications), and AE assessments. The 
safety assessments will be conducted for each patient at specific study Days and Visits, as 
indicated in Table 1. In addition to the safety assessments required by the study protocol, the 
investigator will monitor patients as recommended in the current FDA-approved vigabatrin 
prescribing information. 
6.2.1. 
Demographics and Medical History 
The investigator or designee will record the following information during the Screening Period: 
demographic data, including sex, date of birth, race, ethnicity, medical history, medications 
history, and concomitant medications.  

Insys Development Company, Inc.                                               Protocol Number INS011-16-082

6.2.2. 
Physical Examinations 
The first physical examination will include evaluation of general appearance, ears, eyes, nose, 
and throat (EENT), heart, peripheral vasculature, lungs, musculoskeletal system, abdomen, 
endocrine system, and skin. Height/length and weight will be obtained.  Subsequent brief 
physical exams will consist of general appearance, height/length and weight. Head 
circumference will be collected. 
6.2.3. 
Neurological Examinations 
A complete neurological examination will be performed at Screening, Visit 6, Visit 9 and Early 
Withdrawal. This exam will include mental status, visual assessment, nystagmus, cranial nerves, 
motor and sensory systems, reflexes coordination and gait (if applicable based on age). A brief 
neurological exam will be completed at all other visits; this will not include a visual assessment. 
On Day 4 (Visit 3), and Day 7 (Visit 4) a brief neurological examination will be performed 
predose and approximately 2 hours following administration of the morning dose of the 
investigational product. If needed, additional visual assessments, may be performed based on the 
clinical recommendations for patient’s treatment with vigabatrin. 
6.2.4. 
Vital Signs 
Vital signs will consist of seated or supine blood pressure (depending on patient age and ability), 
pulse rate, temperature, and respiration rate measurements.  
Additional vital sign measurements may be performed as deemed medically necessary by 
research personnel. 
6.2.5. 
Clinical Laboratory Assessments 
6.2.5.1. 
Hematology 
Blood samples for the following hematology assessments will be collected: hemoglobin, 
hematocrit, total and differential leukocyte count, red blood cell (RBC), and platelet count. 
6.2.5.2. 
Chemistry 
Blood samples for the following serum chemistry assessments: albumin, blood urea nitrogen 
(BUN), creatinine, total and direct bilirubin, alkaline phosphatase (ALP), aspartate transaminase 
(AST), alanine transaminase (ALT), sodium (Na+), potassium (K+), chloride (Cl-), lactate 
dehydrogenase (LDH), uric acid, glucose, and calcium.  
6.2.6. 
Adverse Events and Serious Adverse Events 
6.2.6.1. 
Definition of Adverse Events 
An AE is defined as any untoward medical occurrence in a patient administered a pharmaceutical 
product during the course of a clinical investigation. An AE can therefore be any unfavorable 
and unintended sign, symptom, or disease temporally associated with the use of an 
investigational product, whether or not thought to be related to the investigational product. 

Insys Development Company, Inc.                                               Protocol Number INS011-16-082 
05 Jul 2018                                           CONFIDENTIAL                                                                         50  
Patients will be monitored throughout the study for AEs. Monitoring for treatment-emergent AEs 
(TEAEs) will begin as soon as the patient is dosed. All AEs must be followed until they are 
resolved or stabilized, or until all attempts to determine resolution of the event are exhausted. 
The investigator should use their discretion in ordering additional tests as necessary to monitor 
the progress of such events. 
An AE may be: 
• A new illness, not documented in the patient’s medical history; 
• Worsening of a concomitant illness; 
• An effect of the study medication; it could be an abnormal laboratory value, as well 
as a significant shift from baseline within normal range which the qualified 
investigator or medical qualified designate considers to be clinically important; 
• A combination of two or more of these factors. 
Surgical procedures themselves are not AEs. They are therapeutic measures for conditions that 
required surgery. The condition for which the surgery is required is an AE, if it occurs or is 
detected during the study period. Planned surgical measures permitted by the clinical study 
protocol and the conditions(s) leading to these measures are not AEs, if the condition(s) was 
(were) known before the start of study treatment. In the latter case, the condition should be 
reported as medical history. 
Seizures or worsening seizures are not considered AEs as they are considered part of the 
underlying disease. Injuries that occur as a result of a seizure, such as a broken nose, and new 
seizure types will be considered adverse events. 
Patients will be monitored throughout the study for AEs. All AEs must be followed until they are 
resolved or stabilized, or until all attempts to determine resolution of the event are exhausted. 
The investigator should use his/her discretion in ordering additional tests as necessary to monitor 
the progress of such events. 
Adverse events reported prior to dose administration will be recorded as part of the patient’s 
medical history. 
6.2.6.2. 
Classification of Adverse Events 
Adverse events are to be recorded on the AE page of the patient’s case report form (CRF).  
Severity will be graded according to the following definitions: 
• Mild: The patient experiences awareness of symptoms but these are easily tolerated or 
managed without specific treatment. 
• Moderate: The patient experiences discomfort enough to cause interference with 
usual activity, and/or the condition requires specific treatment. 
• Severe: The patient is incapacitated with inability to work or do usual activity, and/or 
the event requires significant treatment measures.

6.2.6.3. 
Causality: Drug Relationship Assessment 
The relationship of the event to the study drug should be determined by the investigator 
according to the following criteria: 
• Definitely related: The event follows a reasonable temporal sequence from the time of 
drug administration that cannot be explained, follows a known or expected response 
pattern to the study drug, that is confirmed by improvement on stopping and 
reappearance of the event on repeated exposure and that could not be reasonably 
explained by other factors such as the patient’s clinical condition, intercurrent illness, or 
concomitant drugs. 
• Probably related: The event follows a reasonable temporal sequence from the time of 
drug administration, and/or follows a known response pattern to the study drug, and 
cannot be reasonably explained by other factors such as the patient’s clinical condition, 
intercurrent illness, or concomitant drugs. 
• Possibly related: The event follows a reasonable temporal sequence from the time of drug 
administration, and/or follows a known response pattern to the study drug, but could have 
been produced by other factors such as the patient’s clinical condition, intercurrent 
illness, or concomitant drugs. 
• Unlikely related: The event follows little or no temporal sequence from the time of drug 
administration that makes a causal relationship improbable and/or other factors such as 
the patient’s clinical condition, intercurrent illness, or concomitant drugs is a more likely 
alternative. 
• Not related: The event is most likely produced by other factors such as the patient’s 
clinical condition, intercurrent illness, or concomitant drugs, and does not follow a 
known response pattern to the study drug, or the temporal relationship of the event to 
study drug administration makes a causal relationship unlikely. 
6.2.6.4. 
Definition of Serious Adverse Events 
A serious AE (SAE) is any AE that fulfills any of the following criteria, as per 21 CFR 312.32: 
• Results in death; 
• Is life-threatening; 
• Requires in-patient hospitalization or prolongation of existing hospitalization; 
• Results in persistent or significant disability or incapacity; 
• Is a congenital anomaly or birth defect; 
• Is medically significant or requires intervention to prevent one of the outcomes listed 
above. 
Serious AEs will be captured from the time of consent through the end of the study. 
6.2.6.5.

6.2.6.7. 
Adverse Event Recording and Reporting 
Adverse events will be recorded throughout the study in the source documents and in the CRFs. 
The investigator will rate AEs for seriousness, intensity, causality, action taken, and outcome as 
described in the previous section. 
Expedited reporting is required for serious unexpected adverse drug reactions. Fatal or 
life-threatening unexpected drug reactions must be reported by the Sponsor to regulatory 
agencies no more than 7 days after the Sponsor’s first knowledge of the reaction; followed by as 
complete a report as possible within 8 additional days. Unexpected adverse drug reactions must 
be reported no later than 15 days after the Sponsor’s first knowledge of the reaction. In order to 
comply with these requirements, the investigator or delegate must inform the Sponsor 
immediately upon occurrence of any SAE. The site will complete the SAE Report Form as 
thoroughly as possible and e-mail it to WCT within 24 hours of the investigators first knowledge 
of the event. 
These SAE reports must contain the following information: 
A. Study name/number 
B. Study drug 
C. Investigator details (name, phone, fax, e-mail) 
D. Patient number 
E. Patient initials 
F. Patient demographics 
G. Clinical event

6.2.6.8. 
Adverse Event Follow-Up 
All non-serious AEs that are not related or unlikely to be related to study treatment will be 
followed until the end of study participation. All SAEs or AEs that are considered as possibly, 
probably, or definitely related to treatment will be followed until resolution or stabilization. 
6.2.6.9. 
Monitoring of AEs Potentially Related to Drug Metabolism 
Cannabidiol inhibits drug metabolism mediated by a subset of CYP proteins (see Section 
Section 1.1.2). Thus, the Investigator and study center staff should monitor patients who are 
taking concomitant medications that are metabolized by CYP2C19, CYP2C9, CYP3A4, 
CYP1A2 or by P-glycoprotein with special care. Medication(s) that is/are strong inhibitor(s) or 
inducer(s) or sensitive substrates of CYP3A4 are exclusionary and prohibited (see Sections 3.2.2 
and Section 4.7.2). However, patients taking medications that are weak inhibitors or inducers of 
CYP3A4 should be monitored with special care.      
6.2.6.10. Data Monitoring Committee 
The Data Safety Monitoring Committee (DSMC) will consist of a least one physician with 
experience in treating IS subjects and at least one biostatistician. The DSMC ensures that the 
ethical principles are observed and monitors the safety of the subjects. To fulfil its 
responsibilities, the DSMC may have access to the clinical data. The DSMC may also meet on an 
ad hoc basis if needed. The DSMC will be informed to what extent the data and analyses 
provided to them have been quality controlled. Members of the DSMC will not be involved in 
other study-related tasks. The DSMC procedures are described in the Data Monitoring 
Committee Charter. 
6.3. 
Pharmacokinetics Assessments 
A blood sample for PK analysis of CBD and 7-OH-CBD will be obtained on Day 15  just prior 
to the second dose during the 24-hour video EEG. Whole blood will be obtained in a 
Vacutainer® tube containing K2-EDTA as a preservative.

All patients will begin tapering off investigational product and vigabatrin at this visit (see 
Section 7.2.2). 
7.2.6. 
Follow-up Period 
A follow-up phone call will occur for all subjects 30 days after discontinuation of the study drug 
to assess AEs, AETs, and record concomitant medications. 
7.2.7. 
Follow-up of Adverse Events 
Any AEs observed from the Screening Visit until the end of the study will be followed to 
resolution. Resolution means that the subject has returned to a baseline state of health or the 
Investigator does not expect any further improvement or worsening of the AE. All AEs that 
occur after the subject completed a clinical study should also be reported to the Sponsor within 
30 days of the last dose of study drug. 
7.3. 
Investigational Product PK Sample   
A blood sample for PK analysis of CBD and 7-OH-CBD will be obtained while inpatient on 
Visit 6 (Day 15, EOS) just prior to the second dose during the 24-hour video EEG. A meal-diary 
will need to be completed on Visit 5 (Day 14) and Visit 6 (Day 15).  
7.4. 
Sample Collection for Patients  
The frequency for PK and safety laboratory samples has been adjusted to avoid excessive blood 
loss in a subset of patients. Multiple standards may be used to determine maximum acceptable 
blood loss in a clinical study. In this study, sample volumes will be adjusted for patients based on 
age to ensure that an excessive amount of blood is not removed. Two (2) metrics that are used to 
determine this volume are discussed below. 
• As per the requirements of the Office for Human Research Protections, no more than 
3 mL/kg per 8-week period should be removed.   
• As per the National Institutes of Health, no more than 7 mL/kg per 6-week period 
should be removed. 
Given the duration of this study, this effectively means that blood loss should not exceed 
approximately 3 mL/kg of body weight per patient for the entire study.

considerations and concepts such as randomization, statistical power, and sample size. There will 
also be a brief discussion on analysis methodology, as well as some data conventions. 
8.1. 
Study Endpoints 
8.1.1. 
Primary Efficacy Endpoint 
The primary efficacy endpoint in this study is: 
• 
Percent of patients who are considered complete responders, defined as complete resolution 
of spasms and hypsarrhythmia, confirmed by 24-hour video EEG from Day 14 to Day 15, as 
determined by the Independent Central Reader. 
8.1.2. 
Secondary Efficacy Endpoints 
The secondary efficacy endpoints in the Initial Treatment Period of this study are: 
• Percent of patients with resolution of infantile spasms as assessed by 24-hour 
video EEG from Day 14 to Day 15 (partial response).

continue: percent of patients who relapse during the Extended Treatment Period 
confirmed by video EEG following parent report of relapse, and time to relapse. 
8.1.3. 
Safety Endpoints 
The safety endpoints of this study are the incidence of treatment-emergent AEs (TEAEs), clinical 
laboratory assessments, vital signs (blood pressure, pulse rate, respiration rate, and temperature), 
physical and neurological examination assessments, medical history, and prior and concomitant 
medications, liver enzymes, and serum bilirubin. 
8.2. 
Sample Size Determination 
A total of 190 patients (130 and 60 patients in the two groups) will provide 80% power with a 
two-sided alpha of 0.05 to detect a difference in response rate, assuming the response with 
vigabatrin alone is 40% and the response with vigabatrin with Cannabidiol Oral Solution is 60%.

8.3. 
Analysis Populations 
Statistical analysis will be done on the following populations: 
• Intent to Treat (ITT) Population: The ITT Population will include all patients who 
were randomized.   
• Safety Population: The Safety Population will include all patients who were treated 
with at least one dose of the study drug.  Patients will be analyzed according to the 
actual treatment they receive.   
• PK Population: The PK Population will include all patients who were treated with at 
least one dose of the study drug and have at least one usable PK measurement. 
8.4. 
Statistical Analyses 
The results of this study will be reported using summary tables, listings, and figures (TLFs), as 
appropriate. Continuous variables will be summarized using descriptive statistics (sample size 
[n], mean, standard deviation [SD], coefficient of variation [CV%; as appropriate], median, 
minimum, maximum, and geometric mean and geometric CV% [as appropriate for PK 
parameters]). Categorical variables will be summarized by presenting the number (frequency) 
and percentage in each category. Differences between treatment groups will be assessed by 
ANCOVA for continuous variables and a chi-square test for categorical variables. Pearson’s 
correlation will be used to quantify the relationship between covariates of interest, and logistic 
regression may be used to simultaneously assess the relationship of multiple variables on 
treatment response (if enrollment provides sufficient sample size). Time to Relapse will be 
described with Kaplan-Meier Curves and treatment groups compared with a log-rank test.

8.4.2. 
Exposure and Compliance 
The exposure to study medication will be summarized by descriptive statistics. 
8.4.3. 
Efficacy Analyses 
A 9-hour video EEG will be conducted during the Screening Period (Baseline) and a 24-hour 
video EEG will be conducted from Day 14 to Day 15 of the Initial Treatment Period. In addition, 
to confirm parent/caregiver report of relapse or complete resolution a 9-hour video EEG will be 
conducted during the Extended Treatment Period. For each video EEG, the number of spasms 
will be counted and the presence of hypsarrhythmia determined. Change from Baseline for each 
measure will be summarized by the median difference. Patients will be defined as having 
Complete Response, Partial Response, or Non-Response on Day 15 as defined in Table 2, the 
percentage of patients who achieve a Complete Response and Partial Responders in each 
treatment arm will be compared using a chi-square test. 
The results of the CGI-I assessments will be listed and summarized by descriptive statistics as 
appropriate. The responses to the seizure diary will also be summarized by dose level and 
scheduled time point. All efficacy summaries will be based on the ITT Population. 
Details of these summaries will be provided in the SAP. For all inferential statistical tests, a 
2-sided type I error rate of 0.05 will be used throughout.  
For the secondary efficacy endpoints, to maintain the trial-wise type I error rate at 0.05, a fixed 
sequence multiple comparisons correction with fallback will be used. The assignment of alpha 
levels to hypotheses being tested will be specified in the SAP. 
For endpoints that are continuous in nature number, the number of observations, mean, median, 
minimum and maximum, and standard deviation (SD) values will be presented as descriptive 
statistics. For inferential statistics:  
• If the normality assumption is met, analysis of covariance (ANCOVA) using the 
baseline value as a covariate will be used.  
• If the normality assumption is not met, a rank-ANCOVA analysis i.e., an ANCOVA 
analysis on rank-transformed data or other non-parametric methods will be used.  
• Time to event analyses will be described with Kaplan-Meier curves and treatment 
groups compared with log-rank tests. 
For endpoints that are categorical in nature, frequency, counts, and percentages will be presented 
as descriptive statistics, and a chi-square test will be used for inferential statistics. 
8.4.3.1. 
Primary Efficacy Analysis 
• Percent of patients with complete resolution of both infantile spasms and 
hypsarrhythmia at Day 15 (complete response) will be compared between vigabatrin 
plus placebo and vigabatrin plus CBD 40 mg/kg/day groups using a chi square test.   
8.4.3.2. 
Secondary Efficacy Analyses 
•  Percent of patients who relapse during the Extended Treatment Period will be 
compared between 14-day vigabatrin + CBD responders and 14-day vigabatrin +

placebo responders using a chi-square test. Time to relapse will be described with 
Kaplan-Meier curves and treatment groups compared using a log-rank test. 
• Percent of patients with complete resolution of infantile spasms at Day 15 will be 
compared between treatment groups using a chi-square test. 
• Percent of patients with complete resolution of hypsarrhythmia at Day 15 using a 
chi-square test. 
• Investigator impression of efficacy and tolerability of study drug (Clinical Global 
Impression – Global Improvement [CGI-I]) will be compared between treatment 
groups using ANCOVA with baseline CGI-S as a covariate. 
• Percent reduction in spasm-free days between the Initial Treatment Period and 
Screening Period will be compared between treatment groups using ANCOVA with 
the baseline score as a covariate. 
Secondary efficacy analyses for patients with a complete response during the Initial Treatment 
Period who continue to the Extended Treatment Period: 
• Percent of patients who relapse during the Extended Treatment Period confirmed by 
video EEG following parent report of relapse.  
• Time to relapse. 
8.4.4. 
Safety and Tolerability Analyses 
The Safety Population will be used for all safety assessments. All safety assessments will be 
descriptive and no inferential statistics are planned for safety assessments. All data listings will 
be provided for protocol specified safety data. 
8.4.4.1. 
Adverse Events 
The Medical Dictionary for Regulatory Activities (MedDRA, version 20.0) will be used to 
classify all AEs. Adverse event summaries will include only treatment-emergent AEs (TEAEs) 
by treatment group. Treatment-emergent adverse events (TEAEs) are defined as AEs that first 
occurred or worsened during the indicated treatment phase. 
The number and percentage of patients with TEAEs will be summarized by system organ class 
(SOC) and preferred term (PT). Summaries of AEs by severity and relationship to the study 
treatment will also be provided. Serious adverse events (SAEs) and AEs resulting in 
discontinuation will be summarized separately in a similar manner. Patient listings of AEs and 
SAEs will be produced. 
8.4.4.2. 
Clinical Laboratory Evaluations 
For the continuous laboratory parameters, descriptive statistics will be presented for values 
collected at Screening, Initial and Extended Treatment, and End of Study/Early Withdrawal 
Visits, and for the changes from baseline to End of Study/Early Withdrawal.

 Vital Signs 
For blood pressure, pulse rate, temperature, and respiration rate, descriptive statistics will be 
presented for values collected at Screening, Initial and Extended Treatment, End of Study /Early 
Withdrawal, and Follow-up Visits, and for the changes from baseline to End of Study /Early 
Withdrawal. 
8.4.4.4. 
Neurological Examination Findings 
Brief neurological examinations will be presented as the number and percentage of patients that 
have normal or abnormal results at Screening (complete exam), Initial and Extended Treatment, 
End of Study, Visit 6 and Visit 9 (complete exam), Early Withdrawal (complete exam), and 
Follow-up Visits. 
8.4.5. 
Pharmacokinetic Analyses 
Exploratory analyses of dose (exposure) will be performed.  Further population PK approach 
may be used for PK parameter calculations, as appropriate. 
8.4.6. 
Missing Data 
There will be no imputation of the missing values. Patients without a video EEG assessment on 
Days 14-15 will be considered non-responders for all EEG-related endpoints. Percentage of 
spasm-free days will be calculated based on the number of entries (up to 15 days per 
measurement period). A sensitivity analysis may be conducted to assess the impact of the 
missing values on the final analysis.  The sensitivity analyses will be detailed in the SAP.

9.7.2. 
Pharmacokinetic/Laboratory Sample Retention 
Laboratory samples may be used for purposes related to this research. The samples will be stored 
until the sponsor has determined that specimens are no longer needed and the decision has been 
made that none of the samples needs to be reanalyzed. In addition, identifiable samples can be 
destroyed at any time at the request of the patient. 
9.8. 
Changes to the Protocol 
The investigator may not deviate from the protocol without a formal protocol amendment 
established and approved by the appropriate IEC/IRB, except when necessary to eliminate 
immediate hazards to the patient or when the change involves only logistical or administrative 
aspects of the study. Any deviation may result in patient withdrawal from the study and 
rendering that patient not available for data evaluation. 
The Investigator or sub-investigator should document any deviation from the protocol and the 
reason. If the Investigator performs a deviation from the protocol or a change of the protocol to 
eliminate an immediate hazard(s) to patients, the record should be immediately submitted to the 
sponsor, the Clinical Research Unit (CRU), and the IRB by the Investigator. The IRB will 
provide expedited review and approval. After the Investigator has obtained approval of the IRB, 
the Investigator should obtain written permission of the CRU and written agreement of the 
sponsor. 
9.9. 
Financial Disclosure 
These issues will be addressed in a separate agreement between the sponsor and the Investigator.

The investigator or his/her designee will inform the parent/caregiver or legal guardian of all 
aspects pertaining to their participation in the study. The process for obtaining informed consent 
will be in accordance with all applicable regulatory requirements (e.g., CFR Part 50 and ICH E6 
Section 4.8). The investigator or his/her designee and the parent/caregiver or legal guardian must 
both sign and date the informed consent document (ICD) before the patient can participate in the 
study. The parent/caregiver or legal guardian will receive a copy of the signed and dated form, 
and the original will be retained in the site’s study records. The decision to participate in the 
study that is made by the parent/caregiver or legal guardian is entirely voluntary. The 
investigator or his/her designee must emphasize to the parent/caregiver or legal guardian that 
consent for study participation may be withdrawn at any time without penalty or loss of benefits 
to which the patient is otherwise entitled. If the ICD is amended during the study the investigator 
must follow all applicable regulatory requirements pertaining to approval of the amended ICD by 
the IEC/IRB, and use of the amended form, including the necessity of re-consenting ongoing 
patients.    
10.5. 
Investigator Reporting Requirements 
In accordance with applicable local regulatory requirements, the investigator may be obligated to 
provide periodic safety updates on the conduct of the study at his/her site and notification of 
study closure to the IRB. Such periodic safety updates and notifications are the responsibility of 
the investigator and not of Insys or its delegate.
