Name of Finished Product: 
Cannabidiol Oral Solution 
Name of Active Ingredient: 
Cannabidiol 
Title of Study: 
A multicenter, open-label, flexible dose study to assess the long-term safety of 
pharmaceutical Cannabidiol Oral Solution as an adjunctive treatment for pediatric 
subjects with a treatment-resistant seizure disorder who complete INS0l 1-14-029 or 
Part A in INS0l 1-15-054 
Phase: 
3b 
Protocol No: 
INS0l 1-14-030 
Study centers: 
Multicenter (approximately 10 sites), United States (US) 
Study duration: Subjects will receive daily oral doses ofCannabidiol Oral Solution for approximately 
48 weeks or until the investigational product is successfully approved for marketing in the US ( whichever 
occurs earlier), inclusive of their treatment on the previous study.- A Final Visit/Discontinuation Visit will be 
completed when the subject completes or stops the study. A Follow-up Visit will be completed 2 weeks after 
the Final Visit/Discontinuation Visit. For subjects enrolling from INS0 11-15-054, their visit entry in 
INS0l 1-14-030 will be determined at the discretion of the sponsor and investigator. Combined study duration 
ofINS0l 1-15-054 and INS0l 1-14-030 will not exceed approximately 48 weeks. 
Objectives: 
• 
To assess the long-term safety ofCannabidiol Oral Solution as an adjunctive treatment for subjects 
with treatment-resistant seizure disorders, including Lennox-Gastaut syndrome (LGS), Dravet 
syndrome (DS) or infantile spasms (IS). 
• 
To establish the continued efficacy of Cannabidiol Oral Solution in maintaining seizure control in 
subjects with treatment-resistant seizures that previously completed INS0l 1-14-029 or Part A (Visit 
6) in INS0l 1-15-054. 
• 
To assess the global status of subjects taking Cannabidiol Oral Solution for an extended period of 
time determined by various qualitative assessments. 
• 
To monitor for changes in plasma levels ofCannabidiol Oral Solution during long-term treatment of 
subjects with treatment-resistant seizure disorders, including LGS, DS or IS. 
• 
Methodology: This is a multicenter, open-label study to assess the long-term safety and efficacy of 
Cannabidiol Oral Solution as adjunctive therapy for pediatric subjects with treatment-resistant 
seizure disorders, including LGS, DS, and IS. Subjects must complete 1 of the following studies to 
be eligible. 
• 
Activities through Day 11 in INS0l 1-14-029 . 
• 
Activities in Part A through Visit 6 in INS0 11-15-054 . 
Eligible subjects will also be medically stable without new, clinically significant comorbidities since the 
Screening Visit in their previous study. 
Subjects should enroll in INS0l 1-14-030 immediately upon completion of the Treatment Period in their 
previous study (to avoid interruption of the investigational product). If rollover does not occur within 
2 weeks after completion of the Treatment Period in their previous study the subjects will need to complete a 
Screening Visit (Visit 1) to confirm continued eligibility. If rollover does occur within 2 weeks after 
completion of the Treatment Period in their previous study Day 11 for INS0l 1-14-029. For subjects enrolling 
from INS0 11-15-054, there should be no interruption of greater than 2 weeks between completing treatment 
in INS0 11-15-054 and initiating treatment in INS0 11-14-030. All assessments for the previous study will be

completed prior to administration of the first dose of Cannabidiol Oral Solution in INS0 11-14-030. Data 
from the baseline visit in the subject's previous study will serve as the baseline for INS0l 1-14-030 where 
applicable. Data collected at the Screening Visit (Visit 1) or Visit 2 (Day 1) of this study will also be 
analyzed as a baseline, whichever visit represents the first visit in the INS0 11-14-030 for each respective 
subject, and as described in Section 8.2.2. 
In this study, all subjects will be dosed as follows: 
• 
Subjects who completed INS0l 1-14-029 will initiate this study on the dos~ with which they were 
being treated previously, unless tolerability issues were observed for a particular subject. 
• 
Subjects who enroll from INS0l 1-15-054 will continue treatment with the dose at which they were 
being treated previously, unless tolerability issues were observed for a particular subject. 
• 
Dosing of the investigational product may be adjusted for an individual subject at any time as per 
Investigator opinion should tolerability issues arise. 
Treatment with established antiepileptic drugs (AEDs) will continue without interruption and changes will be 
permitted as necessary based on safety concerns or changes in seizure control. 
Treatment visits will be scheduled weekly at Visits 3 and 4, then monthly for 3 months, and then quarterly 
thereafter. All subjects will complete a Final Visit/Discontinuation Visit regardless of when they stop 
treatment/complete the study. A Follow-up Visit will occur 2 weeks after the Final Visit/Discontinuation 
Visit. For subjects enrolling from INS0 11-15-054, their visit entry in INS0 11-14-030 will be determined at 
the discretion of the sponsor and investigator. Combined study duration ofINS0l l-15-054 and INS0l l-14-
030 will not exceed approximately 48 weeks. 
At each visit, a record of the incidence and severity of adverse events (AEs), treatment-emergent AEs 
(TEAEs), and Serious Adverse Events (SAEs) will be collected and this will serve as a primary outcome 
criterion for this study. Other safety-related parameters such as 12-lead ECG and hematology, chemistry, 
and urinary analyses will also be assessed at specified visits. Determination of trough plasma levels of 
cannabidiol and its 7-0H metabolite will be performed at each visit except at Visits 3 and 4. Information 
regarding diet (including ketogenic diet), time of the closest meal, and time of drug administration will be 
collected. This will support safety monitoring and establish the extent of variability during long-term 
treatment with the investigational product. For subjects taking clobazam, levels of clobazam and its major 
metabolite (norclobazam) will be measured if there are safety concerns. Seizure diaries will be collected to 
assess control of seizures (frequency, duration, and severity) for one week prior to each quarterly visit. 
At each visit except Visits 3 and 4, the following qualitative assessments will be completed: Clinical Global 
Impression oflmprovement (CGI-1), Clinical Global Impression of Severity (CGI-S), Impact of Pediatric 
Epilepsy Scale (IPES), and Columbia-Suicide Severity Rating Scale (C-SSRS) if appropriate. The Vineland 
Adaptive Behavior Scales, Second Edition - Survey Interview Form including the Maladaptive Behavior 
Index (V ABS) will be collected at Visit 2 and visit 10 or early termination. Subjects enrolled from INS0 11-
15-054 will be excluded from IPES, V ABS, and C-SSRS scores evaluation. 
Planned number of subjects: 
Main criteria for inclusion: 
The study will include subjects who completed activities through 
Day 11 in INS0 11-14-029 or Part A (Visit 6) in INS0 11-15-054. The 
estimated maximum number of rollover subjects from these previous 
studies is as follows: 
• 
INS0l 1-14-029: 60 subjects 
• 
INS0l 1-15-054: 20 subjects 
If all subjects are eligible for and elect to continue into INS0 11-14-030, 
the population of this study will be a maximum of 80 subjects.

Criteria for evaluation: A record of the incidence and severity of treatment-emergent AEs (TEAEs) and 
SAEs throughout the study is the primary criterion. Other safety-related parameters such as 12-lead ECG 
and hematology, chemistry, and urinary analyses will also be assessed. 
Plasma levels of cannabidiol and its 7-hydroxy (OH) metabolite will be evaluated (trough levels). For 
subjects taking clobazam, levels of clobazam and its major metabolite (norclobazam) will be measured if 
there are safety concerns. 
Secondary outcome measures will include control of seizures (frequency, duration, and severity of seizures 
compared to baseline in the previous study), overall changes in global impression assessments by the 
Investigator and parent(s)/caregiver(s) (CGI-I and CGI-S), and change from baseline in IPES, VABS, and C-
SSRS scores, Subjects enrolled from INS0 11-15-054 will be excluded from IPES, V ABS, and C-SSRS 
scores evaluation. 
Statistical methods: The sample size will be determined by the number of subjects that are eligible and 
elect to rollover from INS0 11-14-029 and INS0 11-15-054 into this study. 
Data listings and univariate descriptive summary statistics (number and percentages) will be generated for 
TEAEs and SAEs. The AEs with missing onset dates or AEs with missing onset times occurring on the same 
day as the administration of investigational product will be summarized as TEAEs. Both A Es and SAEs will 
be summarized using the Medical Dictionary for Regulatory Activities (MedDRA). Each verbatim term will 
be mapped to a lower level term, then to a preferred term (PT), and finally to a system organ class (SOC). 
The number and percentage of subjects with ~1 TEAE for each SOC and preferred term will be summarized. 
Laboratory analytes will be summarized as mean change from baseline to endpoint. Shift tables will also be 
produced describing changes from normal to abnormal (high and low) levels or abnormal (high and low) to 
normal levels. 
For each continuous endpoint, descriptive statistics (number, mean, median, minimum, maximum, standard 
deviation [SD], and 95% confidence interval [CI]) will be generated. This analysis will be carried out for the 
change from baseline in frequency, severity, and duration of seizures, IPES, V ABS, and C-SSRS scores, as 
well as parent(s)/caregiver(s) and Investigator CGI-1 and CGI-S. Subjects enrolled from INS0l 1-15-054 will 
be excluded from IPES, V ABS, and C-SSRS scores evaluation. 
Concentrations of cannabidiol and its 7-OH metabolite will be measured at each visit except Visits 3 and 4. 
A descriptive summary of observed blood concentrations (number, mean, median, SD, minimum value, and 
maximum value) will be displayed.

Cannabidiol Oral Solution 
1.0 
INTRODUCTION 
16 
Data presented in Section 1.0 includes overviews from the nonclinical and clinical published 
literature that reports on various other formulations of cannabidiol (primarily plant-based). 
Analogous studies have not been completed for Cannabidiol Oral Solution, the nonplant-
based cannabidiol 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, ~9-tetrahydrocannabinol (~9-THC) is the principal 
psychoactive constituent of marijuana. Cannabidiol is the second most abundant cannabinoid 
and highly physiologically relevant, but is nonpsychoactive. It has demonstrated a potential 
benefit to 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, nonplant-based cannabidiol (Cannabidiol Oral 
Solution). 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 (API) is ~99.5% pure,6 can be consistently produced without the 
concern for contaminants, and will provide cannabidiol to responsibly treat epilepsy. 
1.1.1 
Mechanism of Action 
The mode of action of cannabidiol is not fully understood. The drug substance manifests a 
low affinity for endogenous cannabinoid receptors 1 (CB1) and 2 (CB2). Cannabidiol acts 
primarily 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 theµ- and o-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.1° Finally, cannabidiol may modulate neuronal hyperexcitability through 1 or more of 
the following mechanisms: 
• 
Bidirectional regulation of calcium homeostasis via the mitochondrial 
sodium/calcium exchanger11 
• 
Agonistic properties at 5-hydroxytryptamine la (5-HT1a) receptors12

• 
Enhancing endogenous adenosine levels in the central nervous system (CNS) by 
reducing adenosine re-uptake. 13•14 
1.1.2 
Metabolism and Potential Drug Interactions 
17 
The major biotransformation pathway for cannabidiol is similar to that of other cannabinoids 
and mediated by hydroxylation by CYP proteins. 1s Its interactions with human drug 
metabolizing enzymes (as a substrate, inhibitor, or inducer) were recently reviewed. 16•17 
Details of some interactions may be found below. 
Cannabidiol is metabolized primarily in the liver by cytochrome P 3A4 (CYP3A4) and to a 
lesser extent by cytochrome P450 2Cl 9 (CYP2C19). The effect of cannabidiol on primary 
fetal rat hepatocyte viability was investigated. 18 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. 19,20,21 
Specifically, cannabidiol inhibits CYP3A4, cytochrome P450 3A5 (CYP3A5), and 
cytochrome P450 lAl (CYPlAl) in vitro.22•23•24 It also appears to inhibit 
cytochrome P450 2C9 (CYP2C9)2s and the transport protein p-glycoprotein.26•27 
Cannabidiol likely inhibits drug metabolism when 1 of its metabolites binds to hepatic 
microsomal CYP proteins.28•29•30•31 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. 32 
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 ofhexobarbital in healthy 
volunteers.33 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 119-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 half-
life (t1-2) of /19-THC metabolites.34 It has also been shown that suppression of drug 
metabolism by cannabidiol is diminished following repeated exposure to the drug 
substance.3s

Nonclinical 
Safety 
18 
In a nonclinical setting, single-dose toxicology studies of cannabidiol reveal a relatively safe 
toxicology profile except at very high doses of the drug substance. Repeated dose toxicology 
studies highlight a potential impact of cannabidiol on spermatogenesis, follicle-stimulating 
hormone (FSH) levels, and a subset of immune responses. Full detail of these results may be 
found in the 1B1 and selected data are summarized below. 
• 
In a repeated-dose toxicity study, monkeys treated with oral cannabidiol (0, 30, 100, 
or 300 mg/kg/day), spermatogenesis was inhibited.36 Another study reported 
abnormal sperm in animals exposed to cannabidiol and that paternal exposure to 
cannabidiol is associated with a lower impregnation rate, a 2.3-fold increase in fetal 
loss, and a 5.2-fold increase in postnatal loss.37 
• 
Levels of FSH increased approximately 70% to 100% in Rhesus monkeys dosed with 
100 and 300 mg/kg/day of cannabidiol.38 
• 
Blood sampling following repeated daily injections of 5 mg/kg/day cannabidiol for 
14 days in adult male Wistar rats showed decreased total leukocyte number and total 
numbers ofT and B cells and T helper and T cytotoxic subsets.39 This 
immunosuppressive effect did not affect the total numbers of natural killer (NK) and 
NK T cells that are responsible for the primary, nonspecific antiviral, and antitumor 
immune response. Mechanistically, 0.5 to 10 µM of cannabidiol suppressed 
interleukin-2 (IL-2) and interferon (IFN)-y messenger ribonucleic acid (mRNA) 
expression, proliferation, and cell surface expression of the IL-2 receptor a chain in 
murine splenocyte cell suspensions. 
• 
Human peripheral lymphocytes cultured with 3 .2 x 1 o-6 M cannabidiol for 72 hours 
did not induce chromosomal aberrations.40 Similarly, treatment with 20 to 250 µM 
cannabidiol did not induce unscheduled deoxyribonucleic acid (DNA) repair 
synthesis in cultured human fibroblasts.41 Cultured lymphocytes harvested from prior 
cannabis users receiving oral doses of 1200 mg/day of cannabidiol for 20 days did 
not show an increase in chromosomal aberrations or sister chromatid exchange. 42 
• 
Intraperitoneal (IP) injection of 1 or 10 mg/kg/day into mice resulted in 2- to 6-fold 
increases in chromosomal and nuclear aberrations in bone marrow cells harvest from 
these mice. 43 
o Conversely, human peripheral lymphocytes cultured with 3.2 x 10·6 M 
cannabidiol for 72 hours did not induce chromosomal aberrations.44

Similarly, treatment with 20 to 250 µM cannabidiol did not induce 
unscheduled DNA repair synthesis in cultured human fibroblasts.45 Cultured 
lymphocytes harvested from prior cannabis users receiving oral doses of 
1200 mg/day of cannabidiol for 20 days did not show an increase in

• 
As described in Section 1.1.2, cannabidiol may also affect liver-mediated metabolism 
as a result of its interactions with CYP proteins and p-glycoprotein. 
1.1.3.2 
Efficacy in Epilepsy Animal Models 
Plant-derived cannabidiol shows antiepileptic,47 antipsychotic, antidystonic, anti-emetic, and 
anti-inflammatory properties in animal models.48 These models support exploring the use of 
cannabidiol for the treatment of epilepsy.49 
As an example, the anticonvulsant activity of oral cannabidiol was investigated in adult rat 
model of seizures (induced by maximal electroshock or audiogenic sources). 5° 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 antiseizure drugs (e.g., phenytoin or 
carbamazepine) increased or reduced their anticonvulsant activity, indicating that synergism 
or antagonism with cannabidiol was drug specific. 
1.1.4 
Clinical 
Clinical data described in the following sections were collected following administration of 
various extracts of cannabidiol as oral solutions or solid formulations. 
1.1.4.1 
Pharmacokinetics 
Oral doses of cannabidiol (10 mg/kg/day) once daily for 6 weeks in patients with 
Huntington's disease results in mean weekly plasma concentrations of 5.9 to 11.2 µg/L. 51,52 
The mean t112 for cannabidiol is 24 and 31 hours when administered intravenously (IV) or 
inhaled, respectively, with a range of 18 to 33 hours.53 Cannabidiol is cleared from plasma 
at rates between 960 and 1560 mL/min and the distribution volume is estimated to be 
approximately 30 L/kg.53 
1.1.4.2 
Overview of Safety 
Clinical studies in various human populations indicate that cannabidiol has a favorable side-
effect profile. Doses as high as 1500 mg are well tolerated. 54 No significant reactions or 
serious adverse events (SAEs) have been reported across a wide range of dosages and in both

acute and chronic settings. Bergamaschi et al. 17 recently reviewed the safety of cannabidiol 
in humans examined in 221 subjects across 21 studies. As detailed in the IB, no significant 
safety issues were reported. 
20 
Selected studies in which more detailed information regarding safety outcomes are reviewed 
in Section 1.1.4.2.1. 
Regarding doses of cannabidiol that have been examined in other studies, daily doses of 200 
to 300 mg cannabidiol (or potentially more) may be safe.2•58 Clinical evaluation and 
therapeutic ranges of cannabidiol doses have been reported to be between 10 and 
1500 mg/day, with the majority ofreports evaluating doses in the 300 to 600 mg/day 
cannabidiol range. Furthermore, between 300 and 1500 mg have been used in humans 
without toxicity or SAEs. 51 •55•56•57. Cannabidiol PK has not previously been studied in a 
pediatric population. 
1.1.4.2.1 
Selected Detailed Clinical Safety Data 
The following specific examples detail selected studies of the safety of cannabidiol use in 
humans: 
• 
Ten (10) mg/kg daily dosing of cannabidiol was evaluated in a study of 15 subjects 
diagnosed with Huntington's disease.51 Only 15 abnormal clinical laboratory values 
were associated with cannabidiol treatment; these were largely limited to 4 subjects 
and exhibited no obvious pattern. No significant or clinical differences in cannabidiol 
were observed in a cannabis-specific side-effect inventory. 
• 
Chronic oral administration of 10 mg cannabidiol daily for 21 days does not induce 
any changes in neurological (including electroencephalogram [EEG]), clinical 
(including electrocardiogram [ECG]), psychiatric, blood, or urine examinations in 
both healthy volunteers and epileptic patients.2 
• 
Oral administration of cannabidiol in healthy volunteers (3 mg/kg daily for 30 days) 
and in epileptic subjects (200 to 300 mg daily for 135 days) was well tolerated. No 
signs of toxicity or serious side-effects were detected on neurological and physical 
examinations, blood and urine analysis, ECG, or EEG.2•58 
• 
Administration of single and repeated doses of cannabidiol for up to 20 days at a dose 
of 1200 mg/day does not impact pulse rate and blood pressure in human subjects with 
previous experience to cannabis smoking. 59 
• 
Three (3) subjects with treatment-resistant schizophrenia have been dosed with 40 to 
1280 mg/day of cannabidiol for up to 4 weeks without reporting side-effects.60

INS0I 1-14-030 Amendment 5 
Cannabidiol Oral Solution 
• 
Two (2) subjects diagnosed with bipolar affective disorder did not report adverse 
effects upon receiving 600 to 1200 mg/day of cannabidiol for up to 24 days.61 
1.1.4.3 
Efficacy in Human Epilepsy 
21 
While efficacy is not a primary endpoint for this study (see Section 2.0), several preliminary 
studies of cannabidiol report reductions in seizure activity for a significant subset of subjects. 
Cannabidiol was examined as an adjunctive therapy in 15 subjects with secondary 
generalized epilepsy with temporal focus who were refractory to conventional treatment. 2•3 
The 8 subjects randomized to the active arm received 200 to 300 mg/day of cannabidiol or 
placebo for up to 4.5 months in addition to previously established antiepileptic drugs 
(AEDs).2•58 Subjects tolerated cannabidiol well, with no signs of toxicity or serious side-
effects. Four (4) of the 8 subjects receiving cannabidiol remained almost free of convulsive 
crises throughout the study and 3 others experienced partial improvement. The clinical 
condition of 7 subjects receiving placebo remained unchanged and 1 subject improved. 
Parents of children with treatment-resistant epilepsy have sought cannabidiol-enriched 
cannabis for treatment.4 In a survey, these parents reported dosages of cannabidiol ranging 
from <0.5 to 28.6 mg/kg/day, as per results from medical cannabis testing facilities. Sixteen 
(16; 84%) of the 19 parents eligible to respond to the survey reported a reduction in their 
child's seizure frequency while taking cannabidiol-enriched cannabis. Of these, 2 (11 %) 
reported complete seizure-freedom, 8 (42%) reported >80% reduction in seizure frequency, 
and 6 (32%) reported a 25% to 60% seizure reduction. Reported side-effects included 
fatigue and somnolence. 
Realm Oil is an extract from a strain of cannabis known as Charlotte's Web and contains a 
cannabidiol:~9-THC ratio >20:1. Gedde and Maa5 reported on a small group of pediatric 
subjects diagnosed with various types of epilepsy who took Realm Oil for 2'.:3 months. 
Baseline seizure frequency for these subjects ranged from 5 to 2800 events per week. 
Eight (8; 73%) of these subjects reported a 95% to 100% reduction in seizure occurrence, 
1 (9%) reported 75% reduction, and 2 (18%) reported 20% to 45% reduction. 
1.1.5 
Previous Studies with the lnvestigational Product 
A Phase 1/2 study to examine the pharmacokinetics (PK), safety, and tolerability of 
Cannabidiol Oral Solution in a variety of treatment-resistant seizure disorders (INS0l 1-14-
029) is being conducted. The Sponsor has received an orphan drug designation for 
investigating Cannabidiol Oral Solution in the treatment of Lennox-Gastaut Syndrome (LGS) 
and Dravet Syndrome (DS). Phase 3 studies (INS0 11-14-024 and INS0 11-14-025,

22 
respectively) are planned to examine the safety and efficacy of Cannabidiol Oral Solution in 
the treatment of seizures in LGS and DS subjects. 
Subjects who completed INS0l 1-14-029 or Part A in INS0l 1-15-054 and satisfy the 
inclusion/exclusion criteria detailed in Section 3.4 are eligible to participate in this study. 
1.2 
Pediatric Treatment-Resistant Seizure Disorders 
The clinical manifestations of epilepsy are periodic, uncontrolled, convulsive seizures. The 
highest incidence of epilepsy in North America and Europe is in the first 12 months of life 
when 90 to 212 cases per 100,000 individuals are diagnosed. Children diagnosed with 
various types of epilepsy have an increased risk (23% to 34%) of behavioral and cognitive 
symptoms and comorbidities. 62 
As recently reviewed, 62•63 current interventions for pediatric epilepsy patients include the 
following: 
• 
AEDs 
o The FDA has approved multiple medications (i.e.clonazepam, felbamate, 
lamotrigine, topiramate, rufinamide, and clobazam) for adjunctive use in 
pediatric epilepsy. Although not approved in the US, other AEDs that may be 
used in this population include stiripentol. 
• 
Resective surgery for specific types of drug-resistant focal epilepsy ( e.g., Rasmussen 
encephalitis and tuberous sclerosis complex) 
• 
Ketogenic diet or low-glycemic index diet 
• 
Vagus nerve stimulation (VNS). 
Safety and tolerability issues with current AED therapies include the following: 
• 
Valproic acid: weight gain or loss, nausea and vomiting, pancreatitis, liver failure, 
thrombocytopenia, fetal anomalies if used in pregnancy, polycystic ovarian syndrome 
(PCOS), and hair loss 
• 
Clobazam: irritability, sedation, hypotonia, and drooling 
• 
Topiramate: decreased appetite, weight loss, decreased sweating, slowing of verbal 
processing, kidney stones, acidosis, and glaucoma 
• 
Levetiracetam: behavior and mood issues.

23 
Additionally, some currently approved AEDs have specific contraindications. For example, 
clobazam is excluded as a therapy for patients with significant liver disease or acute narrow 
angle glaucoma. Some AEDs also carry specialized warnings ( e.g., serious skin reactions 
with clobazam and lamotrigine ). 
In addition to the above tolerability issues, 10% to 40% of patients with epilepsy are 
treatment-resistant.64•65•66 The hallmark of treatment-resistance seizures is the failure of 
2:2 AEDs to control them.67 Patients diagnosed with LGS and DS are frequently treatment-
resistant. These indications will be among those investigated in this study ( among other 
treatment-resistant seizure disorders) and will also be examined in planned Phase 3 studies. 
Data from the current study will inform the dose of the investigational product to be 
examined in the Phase 3 studies. 
1.2.1 
Lennox-Gastaut Syndrome 
A severe childhood epileptic encephalopathy, LGS represents an estimated 1 % to 10% of all 
pediatric epilepsies. This pathology typically develops between 3 and 5 years of age, but can 
arise any time between 1 and 8 years of age. 68 According to the Commission on 
Classification and Terminology of the International League Against Epilepsy, LGS is 
characterized by the following: 
• 
Multiple seizure types, including tonic, atonic, and atypical absence 
o Partial, myoclonic, and generalized tonic-clonic seizures may also be 
observed. 
• 
An EEG pattern with diffuse and slow spike-and-wave complexes (<3 Hz) with 
paroxysmal fast rhythms of 10 to 12 Hz in sleep 
• 
Cognitive dysfunction with psychomotor delay and neuropsychiatric problems 
• 
Frequent lesional etiology 
• 
Later onset than comparable pediatric epilepsies. 
In the United Kingdom (UK), the National Institutes of Health and Care Excellence (NICE) 
guidelines (2012) recommend sodium valproate as first-line treatment for LGS, followed by 
lamotrigine (second-line), rufinamide or topiramate (third-line), and felbamate as a last 
therapeutic option. Typical treatment in the United States (US) follows a similar pattern, 
though there are no specific guidelines in this country due to the heterogeneity of patients. 
Each of FDA-approved AEDs for pediatric epilepsy include LGS as an approved indication 
in their labeling. Only approximately 10% of pediatric LGS patients undergo full seizure 
remission with currently available interventions.69,70

A genetic form of pediatric epilepsy, DS occurs in 1 of 20,000 to 40,000 live births. It was 
initially described in 1978 as severe myoclonic epilepsy of infancy (SMEI), and has a high 
rate (15%) of early mortality. 71 Seizures in DS patients typically begin at 5 to 8 months of 
age and are frequently associated with fever in the initial stage of the disease. Seizures may 
be of a variety of types, including: 
• 
Generalized clonic 
• 
Generalized tonic-clonic 
• 
Atypical absence 
• 
Myoclonic 
• 
Focal, with or without secondary generalization 
• 
Tonic (rarely). 
By 2 years of age, many DS patients exhibit other neurologic symptoms, including cognitive 
deficits, lack of attention, and motor dysfunction. 72,73 70% to 80% of patients diagnosed with 
DS exhibit identified mutations in the a subunit of the sodium channel, voltage-gated, 
type 1 (SCNlA) gene.71,74,75 Such mutations are often used to confirm diagnosis. 
In the UK, the NICE guidelines (2012) recommend sodium valproate or topiramate as first-
line treatment for DS, followed by clobazam or stiripentol (second-line). Of the 6 AEDs that 
are FDA-approved for adjunctive use in pediatric epilepsy, none are labeled for the treatment 
of DS. In the US, clinicians may choose to utilize an AED off-label to treat patients with DS 
since there are no approved therapies or treatment algorithms. Typical treatment in the US is 
to maintain patients on a combination ofvalproate with or without topiramate, clobazam, or 
levetiracetam and to use benzodiazepines (e.g., clonazepam, diazepam, lorazepam, or 
midazolam) as rescue therapy. Regardless of the chosen treatment, most cases ofDS are 
refractory to medical management and outcomes are generally poor.76

Study Rationale 
25 
Treatment-resistant seizure disorders, including LGS,DS and IS, are life-time disorders that 
require prolonged exposure to medications to control seizures. This open-label study will 
assess the long-term safety and seizure control of Cannabidiol Oral Solution as an adjunctive 
therapy for the treatment of treatment-resistant seizures in pediatric subjects, including those 
with LGS, DS or IS. 
Safety endpoints were a focus of INS0l 1-14-029 and INS0l 1-15-054, in which short-term 
dosing with the investigational product was examined. The current study will facilitate the 
monitoring of safety and tolerability during long-term treatment with the investigational 
product. 
1.4 
Risk-Benefit Analysis 
As discussed in Sections 1.1.3 and 1.1.4, numerous nonclinical and clinical studies have 
examined other formulations of cannabidiol. Several areas of potential concern have been 
identified with the use of cannabidiol, especially in nonclinical studies. These include: 
• 
Competitive binding of CYP proteins (thus, an impact on drug metabolism in the 
liver). Cannabidiol is metabolized predominantly by CYP3A4 and CYP2C19, and 
may inhibit these 2 isoenzymes, as well as having small effects on CYP3A5, 
CYPlAl, 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-y. 
Based on recent studies of cannabinoid administration in humans, controlled cannabidiol may 
be safe in humans and animals. However, further studies are needed to investigate these 
reported effects. 
The concomitant medication guidelines and safety monitoring (clinical laboratory, ECG, vital 
signs, and physical and neurological examination assessments) planned for this study (see 
Sections 4.9 and 6.1) are intended to minimize these potential safety risks. Levels of 
cannabidiol and its ?-hydroxy (OH) metabolite in the plasma will also be monitored (see 
Section 6.2). 
Stopping criteria for individual subjects will dictate termination of subject participation 
should a safety issue arise (see Section 3.4.3).

This study will allow subjects who previously completed INS0I 1-14-029 or participated in 
INS0I 1-15-054 and completed Part A (visit 6) continued access. This is particularly 
important for those who received therapeutic benefit in terms of seizure control during the 
previous studies. As reviewed in Section 1.2, patients with treatment-resistant seizure 
disorders continue to experience a significant unmet medical need despite ongoing treatment 
with currently available medications and procedures. Devinsky et al. 77 recently noted that 
treatment-resistant seizure disorders are particularly good candidates for cannabidiol 
intervention. 
From a therapeutic perspective, the risk of exacerbating a subject's epilepsy symptoms will 
be minimized by examining the investigational product in an adjunctive setting in 
combination with the subject's established AED(s) treatment regime. Alternations may be 
made to the subject's AED background medication(s) as discussed in Section 4.3. 
In addition to the potential therapeutic benefit noted above, Insys' pharmaceutical grade, 
nonplant-based 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 1'19-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 1'19-THC, herbicides, pesticides, etc. 
1.5 
Compliance 
Each Investigator agrees that the study will be conducted according to the protocol, 
International Conference on Harmonization (ICH), Good Clinical Practice (GCP), and the 
ethical principles that have their origin in the Declaration of Helsinki. The Investigator will 
conduct all aspects of the study in accordance with applicable local law(s) and regulation(s).

Summary of Study Design 
28 
This is a multicenter, open-label study to assess the long-term safety oflnsys' pharmaceutical 
Cannabidiol Oral Solution as adjunctive therapy for pediatric subjects with treatment-
resistant seizure disorders, including LGS, DS and IS. Plasma levels of cannabidiol and its 
7-OH metabolite and efficacy (seizure control and qualitative assessments of subject global 
status) will also be evaluated, though the latter will not be analyzed as endpoints. 
Subjects must complete 1 of the following studies to be eligible for the current study: 
• 
Activities through Day 11 in INS0 11-14-029 
• 
Activities through Part A (Visit 6) in INS0l 1-15-054. 
Eligible subjects will also be medically stable without new, clinically significant 
inclusion/exclusion criteria in Sections 3 .4.1 and 3 .4.2. 
Subjects should enroll in INS0l 1-14-030 immediately upon completion of the 
Treatment Period in their previous study (to avoid interruption of the investigational 
product). Rollover should occur within 2 weeks after completion of the Treatment Period in 
their previous study or when appropriate. A Screening Visit may be required for subjects that 
do not rollover within 14 days of completing their previous study. 
In this study, subjects will be dosed as described below. 
• 
Subjects who completed INS0l 1-14-029 will initiate this study on the dose with 
which they were being treated previously, unless tolerability issues were observed for 
a particular subject. 
• 
Subjects who completed Part A in INS0l 1-15-054 will continue treatment with the 
dose at which they were being treated previously, unless tolerability issues were 
observed for a particular subject. 
Subjects will receive twice daily oral doses of Cannabidiol Oral Solution as described in 
Section 4.1 for approximately 48 weeks or until the investigational product is successfully 
approved for marketing in the US (whichever occurs earlier), inclusive of their treatment on 
the previous study. For subjects that completed INS0l 1-14-029, 48 weeks of treatment 
would be completed under this protocol. For subjects that participated in INS0l 1-15-054,

duration of treatment in INS0l 1-14-030 will be based on the length of time they were 
emolled in INS0l 1-15-054 such that total duration of treatment in both studies combined will 
not exceed approximately 48 weeks. Subjects visit entry into INS0l 1-14-030 will be 
determined at the discretion of the sponsor and the investigator. 
The study will be terminated upon 1 of the following: 
• 
The investigational product is successfully approved for marketing in the US 
• 
Sponsor elects to terminate INS0l 1-14-030. 
Treatment with established background AEDs will continue without interruption and changes 
will be permitted as necessary based on safety concerns or due to changes in seizure control 
as described in Section 4.3. 
As described in Table 1 and Section 5.0, visits will be scheduled at Week 1, Week 2, then 
monthly for 3 months, and then quarterly thereafter. A Screening Visit will be required for 
all subjects that do not rollover within 14 days of completing their previous study. All 
subjects will complete the Final Visit/ Discontinuation Visit regardless of when they stop 
treatment/complete the study. A Follow-up Visit will occur 2 weeks after the Final 
Visit/Discontinuation Visit. 
At each visit, a record of the incidence and severity of adverse events (AEs), treatment-
emergent AEs (TEAEs), and SAEs will be collected and this will serve as a primary outcome 
criterion for this study. Other safety-related parameters such as 12-lead ECG and 
hematology, chemistry, and urinary analyses will also be assessed at specified visits. 
Determination of trough plasma levels of cannabidiol and its 7-0H metabolite will be 
performed at each visit except Visits 3 and 4 (Week 1 and Week 2). This will support safety 
monitoring and establish the extent of variability during long-term treatment with the 
investigational product. For subjects taking clobazam, levels of clobazam and its major 
metabolite (norclobazam) will be measured ifthere are safety concerns. Seizure diaries will 
be reviewed to assess control of seizures (frequency, duration, and severity) throughout the 
duration of the study. 
At each visit except Visits 3 and 4 (Week 1 and Week 2), qualitative assessments will be 
completed as specified in the Schedule of Events (Table 1 ). The Investigator Clinical Global 
Impressions oflmprovement (CGI-I) and Clinical Global Impressions of Severity (CGI-S), 
will be completed for all subjects regardless of chronological and developmental age. Other 
qualitative assessments will be completed in an age-specific manner. This refers to 
developmental age, as discussed below. Specifically:

• 
The Impact of Pediatric Epilepsy Scale (IPES),78•79 is validated for subjects who are 
2 to 16 years of age. Due to developmental delay characteristic of the study 
population, subjects through 18 years of chronological age will complete the IPES. 
Subjects > 18 years of chronological age will not complete the IPES. 
• 
If appropriate, the Columbia-Suicide Severity Rating Scale (C-SSRS) will be 
administered to access suicidality. 
30 
The risk of suicide may be evaluated using the C-SSRS for patients aged >=7 years. Clinical 
impression will be used for patients < 7 years and for patients aged >=7 years with 
development impairment for whom the C-SSRS would be inappropriate. 
The assessments to be completed in this study are discussed in Section 6.0. 
Subject safety will be monitored by a medical and safety data review as described in Section 
3.2. 
3.2 
Medical and Safety Data Review 
The medical and safety data review will be conducted throughout the study in parallel with 
continued subject recruitment, enrollment, and dosing. In addition, the pharmacokineticist 
and statistician may review, as appropriate. Additional experts may be consulted, as 
necessary. 
3.3 
Schedule of Events 
The Schedule of Events may be found in Table 1. 
Subjects should rollover from the previous study as soon as possible following completion of 
Day 11 activities (INSOl 1-14-029) or when appropriate for INSOl 1-15-054 to avoid 
interruption of the investigational product. A Screening Visit may be required for all 
subjects that do not rollover within 14 days of completing their previous study. The duration 
of each subject's treatment will be determined by the duration of treatment the subject 
received in their previous study as described in Section 3 .1. 
Visits will occur weekly for two weeks, monthly for 3 months, and then quarterly thereafter. 
A Screening Period (Visit 1) may be required for all subjects that do not rollover within 14 
days of completing their previous study. All subjects will complete a 
Final Visit/Discontinuation Visit regardless of when they stop treatment/complete the study. 
Discontinuation may occur due to reasons discussed in Sections 3.1 and 3.4.3. A Follow-up 
Visit will occur 2 weeks after the Final Visit/Discontinuation Visit.

quarterly frequency; the definition of quarterly is every 12 weeks (e.g., Weeks 24 and 36). 
e All subjects will complete the Final Visit/ Discontinuation Visit regardless of when they stop treatment/complete the study. 
f The ICF must be completed prior to rollover into INS0l 1-14-030. 
g Vital signs to be assessed are blood pressure, pulse rate, respiratory rate, and temperature. They will be taken after a 5-minute supine 
rest and, if applicable, following simultaneously scheduled ECG meawrements. 
h Fasting is NOT required for collection of plasma levels, hematology and chemistry laboratory samples; whether subject was fasting 
at time of collection should be recorded in the eCRF. Laboratory assessments completed within 14 days prior to administration of 
the first dose of Cannabidiol Oral Solution in INS0l 1-14-030 may be used for Visit 2 (Day 1) (to avoid repetition of procedures). 
i Urinalysis will include macroscopic review; microscopic will be completed if indicated by macroscopic results. Urinalysis completed 
within 14 days prior to administration of the first dose of Cannabidiol Oral Solution in INS0l 1-14-030 may be used for Visit 2 
(Day 1) (to avoid repetition of procedures). 
j The pregnancy test is only required for female subjects of childbearing potential. A serum pregnancy test is required at Screening 
( only for those subjects required to complete the Screening Visit) and urine pregnancy test for all other specified visits. Urine 
pregnancy tests completed within 14 days prior to administration of the first dose of Cannabidiol Oral Solution in INS0 11-14-030 
may be used for Visit 2 (Day 1) (to avoid repetition of procedures). 
k A full physical examination (general appearance, skin, eyes, ears, nose, throat, neck, lymph nodes, chest, heart, abdomen, and 
extremities systems) with neurological examination (developmental age, mental status, cranial nerves, nystagmus, motor system, 
sensory system, reflexes, coordination, gait, and station) will be perfonned at the subject's first visit (Screening or Visit 2. The 
subject's developmental capabilities will be assessed as a part of the neurological examination (in a manner the Investigator sees 
fit) during the Screening Period (Visit 1) or Visit 2 (Day 1) only, whichever visit occurs first for each respective subject. 
A brief neurological examination (mental status, cranial nerves, nystagmus, motor system, sensory system, reflexes, coordination, 
gait, and station) will be performed during other visits. All physical exams will also include an assessment of the subject's height 
and weight. Weight measurements at the quarterly visits may be used to calculate the subject's dose volume. Additional 
examinations may be performed at the discretion of the Investigator. 
1 Seizure diaries will be collected to assess control of seizures (frequency, duration, and severity) for one week prior to each quarterly 
visit. In addition, timing of the administration of the drug and timing and contents of the meals will be collected.

STUDY TREATMENTS 
4.1 
Treatments Administered 
The starting dose of the investigational product will be determined by the study previously 
completed by the subject. 
40 
Subjects who completed INS0l 1-14-029 will initiate this study on the dose with which they 
were being treated previously, unless tolerability issues were observed for a particular 
subject. Subjects who completed Part A in INS0l 1-15-054 will continue treatment with the 
dose at which they were being treated previously unless a tolerability issue was observed for 
a particular subject. 
The Sponsor has developed a dronabinol product, which has a similar chemical composition 
to that of Cannabidiol Oral Solution. The 2 compounds differ in that dronabinol has closed 
ring, while the ring is open in Cannabidiol Oral Solution. Data from a single-dose PK study 
Cannabidiol Oral Solution. 
The strength of the investigational product is discussed in Section 4.3. 
Immediately after dosing, the subject will consume an adequate amount of water or clear 
liquid according to the age of the subject. 
• 
For subjects aged <2 years, 4 ounces of water or clear fluid should be offered and the 
amount consumed recorded in the electronic case report form ( eCRF). 
• 
For subjects aged 2 to <12 years, 5 ounces of water should be offered and the amount 
consumed recorded in the electronic case report form ( eCRF). 
• 
For subjects aged ~12 years, 8 ounces of water should be offered and the amount 
consumed recorded in the electronic case report form (eCRF). 
The subject is not required to fast prior to or after dosing. However, the timing of meals with 
regards to drug administration should be consistent throughout the duration of the study. 
Dosing of the investigational product may be increased or decreased based on efficacy and 
tolerability up to a maximum of 40 mg/kg/day. 
The investigational product will be administered in an adjunctive setting and background 
AED medication(s) will be administered as described in Section 4.3.

Dose Adjustments 
41 
IP dose may be adjusted at the investigators discretion. Dose may be adjusted up or down 
based on efficacy, safety or tolerability. All dose changes must be clearly documented in the 
eCRF. Maximum dose must never exceed 40mg/kg/day. 
4.1.2 
Dose Tapering 
If the subject is not going to continue to receive IPoffered under the Investigator IND 
Expanded Access Program, the subject may be tapered off Cannabidiol Oral Solution based 
on the investigator's preference and subject's tolerability. The investigator should ensure 
that the taper is planned well in advance to allow sufficient time to complete the taper prior 
to the Visit 10 at 48 weeks ( ± 10 days). The date of entering the Expanded Access Program 
will be documented in the EDC. 
4.2 
Identity of Investigational Product 
The active pharmaceutical ingredient (API) in Cannabidiol Oral Solution is a nonplant-based, 
pharmaceutical grade cannabidiol manufactured according to cGMP. It is an off-white to 
pale yellow resin or crystal substance that is soluble in several organic solvents with an acid 
dissociation constant (pKa) of 9.64. The solution is a clear, colorless to pale yellow to brown 
colored solution filled into a 10 mL amber glass bottle. More detailed information may be 
found in the IB. 
4.2.1 
Storage of the Investigational Product 
The investigational product will be stored at controlled room temperature (20 to 25 degrees 
Centigrade, 68 to 77 degrees Fahrenheit) at the study center. The product can also be stored 
refrigerated (2 to 8 degrees Centigrade, 36 to 46 degrees Fahrenheit). 
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. 
The DEA regulations detail specific security requirements for storage of the investigational 
product. 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. 
The investigational product will be dispensed from a Schedule I licensed study center. 
Study centers are required to provide complete information, including eCRFs and final 
outcomes, on all instances of addiction, abuse, misuse, overdose, drug diversion/drug 
accountability, discrepancies in 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 subjects dropped out of the study. 
4.3 
Background Therapy 
Subjects are allowed to remain on their established AEDs throughout the study. For any 
patient the ketogenic diet and VNS settings may also be adjusted. 
Safety issues may be encountered that are associated with concomitant administration of the 
investigational product with the subject's established AEDs that necessitate an alteration in 
AED medication. AED medication(s), including stopping or starting medication(s), may 
be adjusted throughout the trial to maximize seizure control based on tolerability as 
judged by the investigator. 
The Statistical Analysis Plan (SAP) will address how changes in AED medication(s) will be 
addressed from a biostatistical perspective. 
4.4 
Packaging and La belling 
A description of the drug product may be found in Table 2. The investigational product will 
be supplied in either 10 mL or 30 mL amber glass containers of a 300 mg/mL strength.

Selection of Doses in the Study 
For this study, twice daily oral dosing will be initiated as detailed in Section 4.1 based on 
dosing in the subject's previous study. 
Dose reductions of the investigational product may occur due to safety or tolerability 
concerns as described in Section 4 .1.1. and Section 4 .1.2. Dosing of the investigational 
product may also be increased (up to maximum 40 mg/kg/day) for an individual subject as 
per Investigator opinion if there is reason to believe that it is beneficial for the patient. 
4.6 
Selection and Timing of Dose for Each Subject 
Subjects will receive the investigational product twice daily as descried in Section 4.1. 
. 
. 
The subject and/or parent(s)/caregiver(s) will record the date and time for all administrations 
of the investigational product for one week prior to each quarterly visit in the subject 
seizure/dosing diary. On the seizure/dosing diaries parent(s)/caregiver(s) will also record the 
frequency, duration, and severity of seizures for one week prior to each quarterly visit. 
Administration of the investigational product with regards to timing of meals should be 
consistent throughout the study.

SAFETY, PLASMA LEVEL, AND EFFICACY 
ASSESSMENTS AND ENDPOINTS 
6.1 
Safety 
A central objective of this study is to investigate the safety and tolerability of the 
investigational product. This will be done by assessment of the following: 
• 
AEs 
56 
o 
Safety evaluation will consist of TEAEs and SAEs graded according to the 
Medical Dictionary for Regulatory Activities (MedDRA), including deaths. 
This will be captured at every subject visit to the study center. Additionally, 
standard laboratory tests (hematology, chemistry, and urinalysis as detailed in 
Section 6.1.4), 12-lead ECGs, physical and neurological examinations, and 
assessment of vital signs will be performed as indicated in Table 1. 
• 
Clinical chemistry and hematology laboratory results 
• 
Urinalysis 
• 
12-lead ECG 
• 
Vital signs (blood pressure, pulse rate, and respiratory rate) 
• 
Physical and neurological examinations 
• 
C-SSRS (if appropriate). 
6.1.1 
Adverse Events 
An Adverse Event (AE) is any untoward medical occurrence in a subject administered a 
pharmaceutical product. It does not necessarily have a causal relationship with this 
treatment. 
Seizures should not be considered an AE unless they differ significantly from the subjects' 
baseline. The onset of a new seizure type, as well as an injury incurred as a result of any 
seizure should be recorded as an AE. 
A SAE is any untoward medical occurrence ( whether considered to be related to 
investigational product or not) that at any dose: 
• 
Results in death 
06 March 2017 
Confidential 

Insys Development Company, Inc. 
INS0I 1-14-030 Amendment 5 
Cannabidiol Oral Solution 
• 
Is life-threatening 
o This requires that the subject bt nt a risk of death at the time of the event; it 
does not refer to an event that hypothetically might have caused death if it 
were more severe. 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization 
o Hospital admissions and/or surgical operations planned before or during a 
study are not considered AEs if the illness or disease existed before the 
subject was enrolled in the study, provided that it did not deteriorate in an 
unexpected way during the study. 
• 
Results in persistent or significant disability/incapacity 
• 
Is a congenital abnormality/birth defect 
57 
• 
Other medically significant events, which do not meet any of the criteria above, but 
may jeopardize the subject and may require medical or surgical intervention to 
prevent a serious outcome listed in the definition above ( e.g., blood dyscrasias such as 
anemia requiring blood transfusion). 
An adverse drug reaction (ADR) is defined as all noxious and unintended responses to a 
medicinal product related to any dose. An unexpected ADR is defined as any adverse 
reaction, the nature of which is not consistent with the applicable product information. 
The Investigator is responsible for recording all AEs observed during the study through the 
Follow-up Visit. Each AE will be evaluated for duration, severity, frequency, seriousness, 
and causal relationship to the study treatment. Action taken with the study treatment and 
outcome will also be recorded. 
Definitions for severity and causal relationship to the study treatment are presented below. 
Severity 
The severity of the AE will be characterized as mild, moderate, or severe according to the 
following definitions: 
• 
Mild events are usually transient and do not interfere with the subject's daily 
activities. 
• 
Moderate events introduce a low level of inconvenience or concern to the subject and 
may interfere with daily activities. 
• 
Severe events interrupt the subject's usual daily activity.

Cannabidiol Oral Solution 
Relationship 
The Investigator will assess the causal relationship of an AE to the investigational product 
and characterize the AE as unrelated, unlikely, possible, probable, or unknown (unable to 
judge). The following definitions of causality will be used: 
58 
• 
Events can be classified as "unrelated" if there is not a reasonable possibility that the 
study medication caused the AE. 
• 
An "unlikely" relationship suggests that only a remote connection exists between the 
investigational product and the reported AE. With this classification, other 
conditions, including chronic illness, progression or expression of the disease state or 
reaction to concomitant medication, appear to explain the reported AE. 
• 
A "possible" relationship suggests that the association of the AE with the study 
medication is unknown; however, the AE is not reasonably supported by other 
conditions. 
• 
A "probable" relationship suggests that a reasonable temporal sequence of the AE 
with drug administration exists and, in the Investigator's clinical judgment, it is likely 
that a causal relationship exists between the drug administration and the AE. Other 
conditions ( concurrent illness, progression or expression of disease state or 
concomitant medication reactions) do not appear to explain the AE. 
All efforts should be made to classify the AE according to the above categories. The 
category "unknown" (unable to judge) may be used only if the causality is not assessable 
( e.g., because of insufficient evidence, conflicting evidence, conflicting data, or poor 
documentation). 
The frequency of each observed event will be recorded. Clinical actions taken as a result of 
an AEs include pausing, stopping, or delaying dosing of the investigational product. If 
applicable, the resolution of each observed AE will also be recorded; unresolved AEs at the 
time of subject discontinuation will be noted as such. 
6.1.1.1 
Monitoring of AEs Potentially Related to Drug Metabolism 
Cannabidiol inhibits drug metabolism mediated by a subset of CYP proteins (see 
Section 1.1.2). Thus, the Investigator and study center staff should monitor subjects who are 
taking concomitant medications that are metabolized by CYP2C19, CYP2C9, or CYPlAl or 
by p-glycoprotein with special care. Medication(s) that is/are inhibitor(s) or inducer(s) or 
sensitive substrates of CYP3A4 should be monitored with special care. 
06 March 20 l7 
Confidential 

Insys Development Company, Inc. 
INS0 11-14-03 0 Amendment 5 
Cannabidiol Oral Solution 
The CYP proteins noted above metabolize a selection of clinically important AEDs. As 
such, subjects should be monitored for AEs that may be related to a change in the 
metabolism of background AEDs. These may include: 
• 
Increases in liver enzymes 
• 
Increases in side effects associated with background AEDs 
• 
Development of new side effects associated with background AEDs. 
59 
Similarly, several AEDs are known inducers of CYP3A4.24 As such, their use may result in 
alterations in the level of the investigational product. Plasma levels of cannabidiol and 7-0H 
cannabidiol will be assessed as described in Section 6.2. 
The Investigator may choose to assess plasma levels of background AEDs with which the 
subject is being treated should AEs arise that may be due to altered metabolism of these 
medications (see above). As noted in Section 4.3, decisions to alter background AED 
medications and dosing due to safety concerns will be considered on a case by case basis. 
6.1.2 
Reporting of AEs 
The AEs and SAEs will be assessed at all study visits. As noted in Section 6.1.6, endpoints 
for this study include the AE/SAE record for each subject. 
At each visit, information regarding AEs will be elicited from subjects by questioning 
conducted by the study center staff and the subject record will be reviewed with the 
parent(s)/caregiver(s) at each visit. The AEs and SAEs will be assessed at study visits 
according to the schedule indicated in Table 1. As noted in Section 6.1.6, endpoints for this 
study include the AE and SAE record for each subject. 
All AEs, regardless of severity or when they occur, are to be recorded on the appropriate AE 
pages ( either serious or nonserious) in the eCRF. The Investigator should complete all the 
details requested including dates of onset, severity, action taken, outcome, and relationship to 
the investigational product. Each event should be recorded separately. 
Any SAE, including death due to any cause, which occurs during this study, whether or not 
related to the investigational product, must be reported immediately (within 24 hours of the 
study center's first knowledge of the event) by fax to the Sponsor or designee.

In the case of fatal or life-threatening events, please also immediately report by telephone to 
the Sponsor or designee. 
Additional follow-up information should be completed on an SAE follow-up form with a 
copy sent to the Sponsor or designee and the original placed in the SAE section of the eCRF 
binder. 
In medical emergencies, the Investigator should use medical judgment and remove the 
subject from immediate hazard. The Sponsor or designee will be notified regarding the type 
of emergency and course of action taken and the procedures for SAE reporting will be 
followed, if necessary. 
During a subject's participation in the study, the Investigator or institution will provide 
adequate medical care for any AEs, including clinically significant laboratory values related 
to the study. The Investigator or institution should inform a subject when medical care is 
needed for an intercurrent illness ( clinic, laboratory results, or otherwise) which in the 
opinion of the Investigator should receive medical follow-up. 
6.1.2.1 
Reporting of SAEs to Regulatory Authorities and Investigators 
The Investigators will be responsible for submission of SAEs as required to their Institutional 
Review Board (IRB)/Independent Ethics Committee (IEC). The Investigators should provide 
written documentation of IRB notification for each report to the Sponsor or designee. The 
Sponsor or designee will ensure that all SAEs are reported to the appropriate regulatory 
authorities. 
Any additional local IRB/IEC reporting requirements for SAEs should be observed by the 
study center. 
The Sponsor or its representative will be responsible for notification to regulatory agencies.

Follow-Up of AEs 
Any AEs observed will be followed up 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 or designee within 30 days of the last 
administration of the investigational product. 
6.1.4 
Clinical Laboratory Evaluations 
62 
All clinical laboratory tests will be reviewed for results of potential clinical significance 
throughout the study. The Investigator will evaluate any change in laboratory values. If the 
Investigator determines a laboratory abnormality to be clinically significant, it is considered a 
laboratory AE; however, if the abnormal laboratory value is consistent with a current 
diagnosis, it may be documented accordingly. 
The following laboratory tests will be assessed at the time points specified by Table 1. 
• 
Hematology: complete blood count (CBC) with differential, including platelet count, 
neutrophils, lymphocytes, eosinophils, basophils, monocytes, hemoglobin, and 
hematocrit 
• 
Serum chemistry: total protein, albumin, creatinine, blood urea nitrogen (BUN), uric 
acid, total bilirubin, direct bilirubin, alkaline phosphatase, FSH, AST, ALT, glucose, 
calcium, phosphorus, bicarbonate, chloride, sodium, and potassium 
• 
Urinalysis: specific gravity, pH, color, and presence of white blood cells (WBCs), 
red blood cells (RBCs), and proteins 
• 
~-hCG in urine (pregnancy test) 
LFTs (e.g., albumin, direct and total bilirubin, AST, and ALT) will be closely monitored to 
identify any damage that could be induced by the investigational product. 
Levels of FSH will be monitored as a potential surrogate outcome for gametocyte damage. 
Laboratory values outside the reference limits suspected to be of any clinical significance 
will be repeated. Subjects in whom suspected clinical significance is confirmed will either 
not be included or if already enrolled will be followed until normalization or for as long as 
the Investigator considers necessary. Additional laboratory variables may be performed for 
safety reasons if judged appropriate by the Investigator. Further details are provided in the 
Laboratory Manual.

6.1.5 
Vital Signs, Physical Findings and Other Safety Assessments 
63 
Vital signs, physical findings, and other safety assessments will be reviewed for results of 
potential clinical significance throughout the study. The Investigator will evaluate any 
changes. If the Investigator determines that a safety assessment is clinically significant, it is 
considered an AE. However, if the finding is consistent with the subject's current diagnoses, 
it may be documented accordingly. 
6.1.5.1 
Vital Signs 
Vital signs (including blood pressure, pulse rate, respiratory rate, and temperature) will be 
recorded at the time points specified by Table 1. 
If clinically significant findings, as determined by the Investigator, occur in any of the vital 
signs measurements, that measurement will be repeated at medically appropriate intervals 
until the value returns to an acceptable range, a specific diagnosis is established, or the 
condition is otherwise explained. 
6.1.5.2 
Physical and Neurological Examinations 
The full physical examination will consist of the following: general appearance, skin, eyes, 
ears, nose, throat, neck, lymph nodes, chest, heart, abdomen, and extremities. All physical 
exams will also include an assessment of the subject's height and weight. 
A brief neurological examination will consist of the following: mental status, cranial nerves, 
nystagmus, motor system, sensory system, reflexes, coordination, gait, and station. 
The subject's developmental capabilities will be assessed as a part of the neurological 
examination (in a manner the Investigator sees fit) during the Screening Period (Visit 1) or 
Visit 2 (Day 1) only, whichever visit occurs first for each respective subject. 
Additional examinations may be performed at the discretion of the Investigator. 
6.1.5.3 
ECGs 
The ECGs will be performed at the time points specified in Table 1. 
Subjects should be supine for 2:5 minutes prior to the assessment.

performed. 
6.1.5.4 
C-SSRS 
The Columbia-Suicide Rating Scale (C-SSRS) is a prospective assessment tool routinely 
used in studies of drugs with any potential for CNS effects. It captures the occurrence, 
severity, and frequency of suicide-related thoughts and behaviors during the assessment 
period. The risk of suicide will be evaluated using the C-SSRS for patients aged >=7 years. 
Clinical impression will be used for patients < 7 years and for patients with development 
impairment for whom the C-SSRS would be inappropriate. The questionnaires will be 
completed at the time points specified by the schedule of assessments in Table 1. 
6.1.5.5 
Medical/Surgical History 
A complete medical/surgical history will include evaluation (past or present) of the 
following: general, head and neck, eyes, ears, nose, throat, chest/respiratory, 
heart/ cardiovascular, gastrointestinal/liver, gynecological/urogenital, 
musculoskeletal/extremities, skin, neurological/psychiatric, endocrine/metabolic, 
hematological/lymphatic, allergies/drug sensitivities, past surgeries, or any other diseases or 
disorders. 
6.1.6 
Safety-related Endpoints 
The safety-related endpoints are: 
• 
Incidence, type, and severity of AEs and SAEs associated with Cannabidiol Oral 
Solution as an adjunctive treatment for seizures 
• 
Changes from baseline in the previous study in vital signs 
• 
Changes from baseline in the previous study in ECG findings 
• 
Changes from baseline in the previous study laboratory values (hematology, 
chemistry, and urinalysis). 
6.2 
Plasma Levels 
Whole blood will be obtained in a Vacutainer® containing heparin anticoagulant for the 
determination of the plasma levels of cannabidiol and 7-0H cannabidiol in human plasma. 
The sample will be obtained as indicated in Table 1 prior to daily study medication dosing on 
that day. Samples for plasma level assessment of cannabidiol and 7-0H cannabidiol should 
06 March 2017

be collected immediately prior to administration of the morning dose of the investigational 
product on indicated days. 
The following information will be captured for blood sample collection in each subject's 
eCRF: 
• 
Subject number and initials 
65 
• 
Time and date of most recent administration of the investigational product prior to the 
sample collected for plasma level analysis 
• 
Time and date of each blood sample collected for plasma level analysis 
• 
Time and date of subject's ingestion of food (i.e., the evening meal on the day prior to 
each study visit). 
Samples for the determination of the investigational product in human plasma will be 
analyzed by the Sponsor, using an appropriate bioanalytical method. It is anticipated that this 
will include estimates of concentration and trough (steady state) concentration of cannabidiol 
and 7-OH cannabidiol (monthly to quarterly). For subjects taking clobazam, levels of 
clobazam and its major metabolite (norclobazam) will be measured if there are safety 
concerns. 
The analytical method for human plasma will be developed and validated. All samples still 
within the known stability of the investigational product will be analyzed. 
Exploratory plasma samples will be shipped to the Sponsor or the Sponsor-designated 
bioanalytical laboratory. 
6.2.1 
Plasma Levels-related Endpoint 
The plasma level-related endpoint is trough (steady state) concentrations of Cannabidiol Oral 
Solution throughout approximately 48 weeks of continuous exposure or until the 
investigational product is successfully approved for marketing in the US (whichever occurs 
earlier), inclusive of the subject's treatment on their previous study.

Efficacy 
6.3.1 
Seizure Control 
In this study, seizure frequency, duration, and severity will be assessed to monitor seizure 
control achieved by long-term treatment with Cannabidiol Oral Solution. Seizures will be 
observed and recorded using a patient reported outcome (PRO) instrument (i.e.,

subject/caregiver diaries). The exact format and version(s) of diary to be used will also be 
included in the eCRF. Diaries will be dispensed at Visits 7, 8, and 9 (Weeks 12, 24, and 
36) and reviewed and completed pages collected (if applicable) during each visit. 
For the purposes of this study, only observable seizures will be quantified in the one week 
prior to Visits 8, 9, and 10. All seizures should be recorded by the parent(s)/caregiver(s) 
and/or subject (if applicable) in the diary. 
66 
Given that continuous seizures may be observed in some subjects (i.e., multiple seizures may 
occur without break), it may not be possible to accurately record all seizures for these 
subjects. If necessary, the parent(s)/caregiver(s) or subject (if applicable) will, at a 
minimum, categorize the seizure frequency ( for seizures others than tonic or atonic seizures) 
by range (i.e., diaries will record the count of seizures per day as >50 seizures/day, 20 to 
50 seizures/day, 6 to 19 seizures/day, 1 to 5 seizures/day, or no seizures). 
The subject and/or his/her parent(s)/caregiver(s) are responsible for completing the diary. 
The party who is primarily responsible will be chosen by the Investigator in consultation with 
the subject's parent(s)/caregiver(s). If a pediatric subject will be entering diary data, the 
parent(s)/caregiver(s) should provide guidance and monitor accuracy and completeness. 
6.3.1.1 
Subject Seizure and Dosing Diary Education 
Similar to INS0 11-14-029 and INS0 11-15-054, ongoing training and re-education of the 
parent( s )/caregiver( s) and (if applicable) the subject will occur under the direction of the 
Investigator and Study Coordinator. 
To this end, the Investigator and study center staff are expected to provide appropriate 
(refresher) training to subjects and/or their parent(s)/caregiver(s) regarding data to be 
collected. To satisfy the needs of all seizure-related efficacy endpoints, training will include 
a number of topics: 
• 
Recognition of seizure activity 
o Such training will facilitate the counting of seizures to satisfy the primary 
efficacy endpoint, as well as other efficacy-related endpoints. 
o For the purposes of this study, a seizure will be defined as uncontrolled 
electrical activity in the brain that may produce a physical convulsion, minor 
physical signs, thought disturbances, or a combination of symptoms. 
• 
Recognition of the characteristics of relevant seizure types as described in Section 
6.3.1.1.1 
06 March 2017

Cannabidiol Oral Solution 
• 
Quantification of seizure severity as described in Section 6.3.1.1.3 
• 
Quantification of seizure duration as described in Section 6.3 .1.1.3 
67 
It is anticipated that training on the above topics will allow the parent(s)/caregiver(s) and 
subject (if applicable) to completely and accurately record seizure activity. The Investigator 
is responsible for ensuring that the parent(s)/caregiver(s) and subject (if applicable) are 
properly trained to complete the diary. Competency will be confirmed by review of diary 
entries with parent(s)/caregiver(s) and subject (if applicable) at each study center visit (see 
Table 1) so the Investigator and study center staff can monitor the quality of record-keeping. 
The subject seizure and dosing diary for this study was designed to satisfy current FDA 
guidance regarding PROs (i.e., the Guidance for Industry Patient-Reported Outcome 
Measures: Use in Medical Product Development to Support Labeling Claims). 
6.3.1.1.1 
Seizure Type Identification 
Characteristics of the seizure types to be observed and recorded for efficacy assessments (i.e., 
subject/caregiver diaries) include: 
• 
Tonic: body stiffening, upward deviation of the eyes, pupil dilation, and altered 
respiratory patterns 
• 
Atonic: brief loss of muscle tone and consciousness, that may result in an abrupt fall 
• 
Myoclonic: sudden muscle jerks and including infantile spasms 
• 
Tonic-clonic: jerking preceded by stiffening 
• 
Clonic: repeated jerking 
• 
Absence: lapses of awareness, sometimes with staring 
• 
Febrile: seizure of various types (especially tonic-clonic) associated with high fever 
• 
Focal: typically involving 1 side and/or region of the body, twitching, and grimacing 
• 
Atypical absence: staring (as in an absence seizure), but subject may also be 
somewhat responsive. 
These observable characteristics will be utilized to assist the parents(s)/caregiver(s) and 
subject (if applicable) in categorizing seizures types in the subject seizure and dosing diary. 
The Investigator will fully train the parents(s)/caregiver(s) and subject (if applicable) in 
methods to identify seizure type.

6.3.1.1.2 
Seizure Severity Assessment 
Subject/caregiver diaries will also be utilized to record seizure severity. Overall, seizure 
severity will be captured using the CGI-S as described in Section 6.3.3. This scale will be 
completed as noted in Table 1. 
Seizure severity will be determined by the parent(s)/caregiver(s). In the subject seizure and 
dosing diary, the Investigators will work with the parent(s)/caregiver(s) to record an 
assessment of seizure severity based on the following: 
• 
Postictal events and duration 
• 
Occurrence of injuries 
• 
Overall functional impairment. 
The Investigator and study center staff are expected to provide appropriate training to 
subjects and/or the parent(s)/caregiver(s) regarding data to be collected. 
6.3.1.1.3 
Seizure Duration Assessment 
68 
Seizure duration will be quantified by approximate timing by the caregiver or other observer, 
and recorded in the subject seizure and dosing diary. The Investigator and study center staff 
are expected to provide appropriate training to subjects and/or their parent(s)/caregiver(s) 
regarding recording seizure duration. 
6.3.2 
Additional Information to be Recorded in Subject Seizure and Dosing Diary 
The subject seizure and dosing diary will include a record of the date and time of each 
administration of the investigational product in the one week prior to Visits 8, 9, and 10. 
6.3.3 
Qualitative Assessments 
In this study, the global status of each subject will be monitoring using a set of qualitative 
assessment tools administered at specified visits: 
• 
CGI-I 
• 
CGI-S 
• 
IPES 
•

7.0 QUALITY CONTROL AND QUALITY ASSURANCE 
70 
According to the ICH Guidelines of GCP (CPMP/ICH/135/95), the Sponsor is responsible 
for implementing and maintaining quality assurance and quality control systems with written 
standard operating procedures (SOPs). 
Quality control will be applied to each stage of data handling. 
The following steps will be taken to ensure the accuracy, consistency, completeness, and 
reliability of the data: 
• 
Investigator and study center staff familiarity with GCP/ICH 
• 
Investigator Meeting(s), including protocol and study systems training 
• 
Instruction manuals for investigational product, IVRS, EDC, and any other systems 
included in study operation 
= 
• 
Study Center Initiation Visit 
• 
Early study center visit following enrollment of the first subject 
• 
Routine study center monitoring 
• 
Ongoing study center communication and training 
• 
Data management quality control checks 
• 
Continuous data acquisition and cleaning 
• 
Internal review of data 
• 
Quality control check of the final clinical study report (CSR). 
In addition, the Sponsor and/or designee may conduct periodic audits of the study processes, 
including, but not limited to the study center, study center visits, central laboratories, 
vendors, clinical database, and final CSR. When audits are conducted, access must be 
authorized for all study related documents including medical history and concomitant 
medication documentation to authorized Sponsor's representatives and regulatory authorities.

7 .1 
Monitoring 
The Sponsor may engage the services of a contract research organization (CRO) to perform 
all monitoring functions within this clinical study. Monitoring will occur according to GCP 
and the designee's monitors will work in accordance with their SOPs and have the same 
rights and responsibilities as monitors from the Sponsor. Monitors will establish and 
maintain regular contact between the Investigator and the Sponsor. 
71 
Monitors will evaluate the competence of the study center, informing the Sponsor about any 
problems relating to facilities, technical equipment or medical staff. During the study, 
monitors will check that written informed consent has been obtained from all subjects 
correctly and that data are recorded correctly and completely. Monitors are also entitled to 
compare entries in eCRFs with corresponding source data and to inform the Investigator of 
any errors or omissions. Monitors will also control adherence to the protocol at the study 
center. They will arrange for the supply of investigational product and ensure appropriate 
storage conditions are maintained. 
Monitoring visits will be conducted according to all applicable regulatory requirements and 
standards. Regular monitoring visits will be made to each center while subjects are enrolled 
in the study. The monitor will make written reports to the Sponsor on each occasion contact 
with the Investigator is made, regardless of whether it is by phone or in person. 
During monitoring visits, all entries in the eCRFs will be compared with the original source 
documents (source data verification). 
7.2 
Data Management/Coding 
Data generated within this study will be handled according to the relevant SOPs of the data 
management and biostatistics departments of the Sponsor or designee. 
A Code of Federal Regulations (CFR) Title 21, Part I I-compliant EDC system will be used 
for this study, meaning that all eCRF data will be entered in electronic forms at the study 
center. The eCRFs will be produced by the Sponsor or designee for each subject. Where 
eCRFs are not possible, the source data will be captured on paper. 
Data collection will be completed by authorized study center staff designated by the 
Investigator. Appropriate training and security measures will be completed with the 
Investigator and all authorized study center staff prior to the study being initiated and any 
data being entered into the system for any study subjects. 
All data must be entered in English. The eCRFs should always reflect the latest observations 
on the subjects participating in the study. Therefore, the eCRFs are to be completed as soon 
06 March 20 I 7 
Confidential 

Insys Development Company, Inc. 
INS0I l-14-030 Amendment 5 
Cannabidiol Oral Solution 
72 
as possible during or after the subject's visit. To avoid inter-observer variability, every effort 
should be made to ensure that the same individual who made the initial baseline 
determinations completes all plasma level and safety evaluations. The Investigator must 
verify that all data entries in the eCRFs are accurate and correct. If some assessments are not 
done, or if certain information is not available or not applicable or unknown, the Investigator 
should indicate this in the eCRF. The Investigator will be required to electronically sign off 
on the clinical data. 
The monitor will review the eCRFs and evaluate them for completeness and consistency. 
The eCRF will be compared with the source documents to ensure that there are no 
discrepancies between critical data. All entries, corrections and alterations are to be made by 
the responsible Investigator or designee. The monitor cannot enter data in the eCRFs. Once 
clinical data of the eCRF have been submitted to the central server, corrections to the data 
fields will be audit trailed, meaning that the reason for change, the name of the person who 
performed the change, together with time and date will be logged. Roles and rights of the 
study center staff responsible for entering the clinical data into the eCRF will be determined 
in advance. If additional corrections are needed, the responsible monitor or Data Manager 
will raise a query in the EDC application. The appropriate study center staff will answer 
queries sent to the Investigator. This will be audit trailed by the EDC application meaning 
that the name of investigational staff, time and date stamp are captured. 
The eCRF is essentially considered a data entry form and should not constitute the original 
( or source) medical records unless otherwise specified. Source documents are all documents 
used by the Investigator or hospital that relate to the subject's medical history, that verify the 
existence of the subject, the inclusion and exclusion criteria and all records covering the 
subject's participation in the study. They include laboratory notes, ECG results, memoranda, 
pharmacy dispensing records, subject files, etc. 
The Investigator is responsible for maintaining source documents. These will be made 
available for inspection by the study monitor at each monitoring visit. The Investigator must 
submit a completed eCRF for each subject who receives investigational product, regardless 
of duration. All supportive documentation submitted with the eCRF, such as laboratory or 
hospital records, should be clearly identified with the study and subject number. Any 
personal information, including subject name, should be removed or rendered illegible to 
preserve individual confidentiality. 
The eCRFs will be automatically appended with the identification of the creator, by means of 
their unique UserID. Specified records will be electronically signed by the Investigator to 
document his/her review of the data and acknowledgement that the data are accurate. This 
will be facilitated by means of the Investigator's unique U serID and password; date and time

stamps will be added automatically at time of electronic signature. If an entry on an eCRF 
requires change, the correction should be made in accordance with the relevant software 
procedures. All changes will be fully recorded in a protected audit trail, and a reason for the 
change will be required. 
Concomitant diseases/medical history and AEs will be coded using the Medical Dictionary 
for Regulatory Activities (MedDRA). Concomitant medications will be coded using the 
World Health Organization's Drug-Dictionary (WHO-DD). 
7.3 
Quality Assurance Audit 
The study center, the study database, and study documentation may be subject to quality 
assurance audits during the course of the study by the Sponsor or a designee on behalf of the 
Sponsor. In addition, inspections may be conducted by regulatory bodies at their discretion. 
The Investigator will ensure the accuracy, completeness, and timeliness of the data recorded 
for data queries and all required reports according to any instructions provided.

General Statistical Considerations 
8.2.1 
Statistical Methods and Analysis Plan 
This section describes the planned statistical analyses in general terms. A complete 
description of the methodology will be specified in the SAP. Any changes in the statistical 
methods described in this protocol that occur prior to database lock will be documented in 
the SAP and will not require a protocol amendment. 
8.2.2 
General 
Since this is an extension study ofINSOl 1-14-029 and INSOl 1-15-054 data for INSOl 1-14-
030 will be presented for the extension period only (i.e., not for the entire period spanning 
INSOl 1-14-029 and INSOl l-15-054 and INSOl 1-14-030 studies). 
Categorical variables will be summarized using frequencies and percentages. Continuous 
variables will be summarized using descriptive statistics (number, mean, standard deviation 
[SD], median, minimum, and maximum). 
Baseline for this study will be the same as that defined in protocols INSO 11-14-029 and 
INSOl 1-15-054, respectively. Additionally, all data from this study will also be compared to 
the intra-study baseline ( data from the subject's first visit [i.e., Visit 1 [Screening] or Visit 2 
[Day 1]). For assessments that were not completed in INSOl l-14-029 (i.e., IPES and 
VABS), the only baseline will be data collected at Visit 2 (Day 1) ofINSOl 1-14-030. (Data 
from subjects enrolling through INSOl 1-15-054 may be excluded from the analysis) 
Data collected at unscheduled time points will not be summarized at the unscheduled time 
points. 
Data will be presented for each dose (10, 20, and 40 mg/kg/day) and for all doses combined 
together (overall), corresponding to the dose at which subject will initiate this study (as 
described in Section 4.1 ). When appropriate, raw data will be presented by visit (Visit 1

and then quarterly thereafter). 
No statistical hypothesis testing is planned for this study. 
A detailed SAP will be finalized prior to database lock. 
8.2.3 
Data to be Analyzed 
The data will be inspected for inconsistencies by performing validation checks. 
All details regarding the statistical analysis and the preparation of tables, listings, and figures 
(TLFs) will be described in the SAP prepared by the Sponsor or by a designee and approved 
by the Sponsor before database lock.

8.3.1 
Subject Population for Analysis 
The analysis population will be the Safety Population, which will include all subjects who 
receive 2'.:l dose of the investigational product. In the event that a subject receives treatment 
other than that specified in the protocol, safety analyses will be conducted according to the 
treatment the subject actually received. 
All safety-related endpoints and efficacy-related data will be analyzed using the Safety 
Population. 
8.3.2 
Subject Disposition 
The number of subjects who receive each dose and the duration of exposure will be 
summarized for the Safety Population. 
Prior and concomitant therapies will be listed. The frequency and percentage of subjects 
who use prior or concomitant medication will be summarized by preferred term (PT), 
utilizing WHO-DD definition and treatment regimen for each dose and overall. Concomitant 
medications will also be checked for protocol deviations. 
Subjects who take prohibited concomitant medications will be noted in the summary of 
protocol deviations.

76 
Demographic data and subject characteristics will be listed and summarized by dose and for 
all subjects using descriptive statistics (mean, number, SD, median, minimum, and maximum 
values for continuous variables and counts and percentages for categorical variables). 
Past and current medical history will be summarized by dose and overall using the system 
organ class (SOC) as coded using the MedDRA coding dictionary. If both a past and current 
( ongoing) medical condition record are indicated for a condition, the condition will be 
presented under current medical conditions only. 
8.3.4 
Safety Analysis 
The assessment of safety will be based on the analyses of AEs, vital signs, 12-lead ECG, and 
clinical laboratory evaluations. All safety analyses will be performed on the Safety 
Population. Safety endpoints are described in Section 6.1.6. 
8.3.4.1 
AEs 
The TEAEs are defined as AEs that first occw· or worsen in severity after the first 
administration of the investigational product. Such AEs will be coded using the MedDRA 
coding dictionary and will be summarized by presenting the number and percentage of 
subjects having any AE, having an AE in each SOC, and having each individual AE as 
reported by PT. Furthermore, a summary for SAEs and summaries by severity and 
relationship to the investigational product will be presented by dose and overall. The most 
frequent (5%) AEs and drug related AEs will also be provided. 
All percentages will be based on the number of subjects in the Safety Population. 
In the summaries, AEs will be counted only once per subject. If a subject reports the same 
AE more than once, it will be counted with its worst severity and closest relationship to 
investigational product. Only those AEs that begin between start and end of study will be 
summarized. 
The AEs will also be listed by subject and dose. 
Subject death due to any cause and subjects with AEs leading to investigational product 
discontinuation will be listed and summarized by dose and overall. 
The proportion of subjects that discontinue investigational product or experience dose 
interruption due to treatment emergent AEs will be summarized by dose and for all subjects.

Assent Form and any other written information and/or materials to be provided to the 
subjects. The Investigator will provide the Sponsor or a designee with documentation of IRB 
approval of the protocol and informed consent before the study may begin at the study center. 
The Investigator should submit the written approval to the Sponsor or designee before 
enrolment of any subject into the study. 
The Sponsor or a representative should approve any modifications to the ICF that are needed 
to meet local requirements. 
The Investigator will supply documentation to the Sponsor or designee of required IRB/IEC 
annual renewal of the protocol, and any approvals of revisions to the ICF, assent form, or 
amendments to the protocol. 
The Investigator will report promptly to the IRB/IEC, any new information that may 
adversely affect the safety of subjects or the conduct of the study. Similarly, the Investigator 
will submit written summaries of the study status to the IRB/IEC annually, or more

Subject Information and Informed Consent 
80 
The ICF will be used to explain the risks and benefits of study participation to the subject in 
simple terms before the subject will be entered into the study. The ICF contains a statement 
that the consent is freely given, that the subject is aware of the risks and benefits of entering 
the study, and that the subject is free to withdraw from the study at any time. Written 
consent must be given by the subject and/or legal representative, after the receipt of detailed 
information on the study. 
The Investigator is responsible for ensuring that informed consent is obtained from each 
subject or legal representative and for obtaining the appropriate signatures and dates on the 
ICF and assent form (if applicable) prior to the performance of any protocol procedures and 
prior to the administration of study medication. The Investigator will provide each subject 
with a copy of the signed and dak<l ICF. 
9.3.1 
Subject Assent Guidance 
This study may enroll children as young as 1 year of age (see Section 3.4.1). The IRB/IEC 
must determine, to the extent required by 45 Cr'R §46.116, that adequate provisions are made 
for soliciting the assent of pediatric subjects (when the IRB/IEC judges that they are capable 
of providing assent), as well as the permission of the parents (45 CFR §46.408). Permission 
means the agreement of parent(s) or guardian to the participation of their child or ward in 
research (45 CFR §46.402(c)). Local and regional/state regulations will also be addressed as 
applicable. 
If the IRB/IEC determines that the capability of some or all of the children is so limited that 
they cannot reasonably be consulted regarding assent, or that the intervention or procedure 
involved in the research holds out a prospect of direct benefit that is important to the health 
or well-being of the children, and is available only in the context of the research, the assent 
of the children is not a necessary condition for proceeding with the research. Even where the 
IRB/IEC determines that the subjects are capable of assenting, the IRB/IEC may still waive 
the assent requirement under certain circumstances in accord with 45 CFR §46.116 and 
45 CFR §46.408(a). 
The IRB/IEC and local regulations will determine the age at which assent of subjects in this 
study will not be required. Informed consent from all parent(s)/caregiver(s) will be required.

Changes in the Planned Analyses 
Changes that were made to the planned analyses after the finalization of the SAP were as 
follows: 
• 
Given that an Investigator could have chosen to down-titrate or up-titrate subjects to any 
dose, results were not analyzed and presented “by dose and overall” as was stated in the 
protocol.  On 13 October 2016, it was decided that summaries should only be presented 
by age category and overall as described in Sections 9 to 17 of the SAP 
(Appendix 16.1.9).
