from Baseline to End of Study). 
• To assess the efficacy of Cannabidiol Oral Solution by measuring the changes in 
Patient Global Impression of Change (PGI-C). 
• To assess the safety and tolerability of Cannabidiol Oral Solution in patients with 
PWS. 
• To assess the efficacy of Cannabidiol Oral Solution on eating behavior in patients 
with PWS as measured by the Three Factor Eating Questionnaire-18-item version 
(TFEQ-R18). 
• To assess the impact on Quality of Life in patients with PWS as measured by the 
PROMIS® Life Satisfaction and Positive Affect short-form questionnaires.

• To assess the impact on physical activity in patients with PWS as measured by the 
PROMIS Physical Activity and Fatigue questionnaires. 
Exploratory: 
• To assess the efficacy of Cannabidiol Oral Solution on body composition, and bone 
mineral density, as measured by dual-energy X-ray absorptiometry (DEXA).  
Methodology:  
This is a double-blind, randomized, placebo-controlled, Phase 2 clinical trial in patients 
diagnosed with Prader-Willi Syndrome. Patients will receive either Cannabidiol Oral 
Solution (40 mg/kg/day) or placebo with patients randomized in a 1:1 ratio. Randomization 
will be stratified according to use of growth hormone treatment.  
Approximately 66 male and female patients aged 8 to 17 years, inclusive, with a genetically 
confirmed diagnosis of Prader-Willi Syndrome will be enrolled in the study.  
The study will consist of the following six periods: 
• Screening Period (2 weeks) 
• Placebo Lead-In Period (2 weeks) 
• Titration Period (1 week) 
• Maintenance Period (12 weeks) 
• Taper Period (1 week) 
• Follow-Up Period (1 week) 
Patients who meet entry criteria will be assigned to a 2-week single-blind Placebo Lead-In 
Period. Following the placebo single-blind lead-in period, patients will be randomly assigned 
to receive double-blind treatment with either Cannabidiol Oral Solution treatment at a dose of 
40 mg/kg/day or matching placebo divided twice daily with standard meal (a 1-week 
Titration Period followed by a 12-week Maintenance Period). During the Titration Period, 
Cannabidiol Oral Solution will be titrated as follows: Days 1-3: 20 mg/kg/day, Days 4-6: 30 
mg/kg/day, Day 7: 40 mg/kg/day. The Investigator or designee will call on Day 3 and Day 6 
to determine if the patient’s dose may be titrated to the next dose level. If the Investigator 
determines that the patient is unable to tolerate the higher dose, the patient should be 
withdrawn from the study. 
During the Maintenance Period, patients may have their dose of blinded study medication 
adjusted down to 30 mg/kg/day at the discretion of the Investigator or qualified designee 
based on the patient’s tolerability.   
After completion of the study, patients will be offered the opportunity to enroll in an open-
label, long-term safety study. Patients who do not elect to enroll in the long-term safety study 
will be tapered off the study drug over 7 days according to the following schedule: 
40 mg/kg/day to 30 mg/kg/day for 3 days, 30 mg/kg/day to 20 mg/kg/day for 3 days, 
discontinuing the drug on Day 7. A final safety follow-up will be conducted 2 weeks after 
study completion (Visit 10) for patients who do not elect to continue into the long-term safety 
study.

8 
The safety endpoints are treatment-emergent AEs (TEAEs), clinical laboratory assessments, 
vital signs (blood pressure, pulse rate, respiration rate, and temperature), 12-lead ECGs, 
physical examination assessments, pregnancy screens, urine drug screen (including THC), 
medical history, and prior and concomitant medications.   
Pharmacokinetic 
• Trough concentrations (Ctrough) of cannabidiol (CBD) and metabolite 7-hydoxy-CBD 
(7-OH CBD) will be used to assess the exposure-response relationship. 
Statistical Methods: 
Sample Size Calculation 
A total of 30 patients per treatment group will provide more than 85% power with an alpha of 
0.05, for a difference in the HQ-CT from Baseline to Week 13 of 5 points with standard 
deviation of 6. Assuming a 20% drop out rate, approximately 66 patients (33 patients per 
arm) will be randomized to achieve 60 (30 patients/arm) completers. 
Analysis Populations 
Statistical analyses will be conducted on the following populations: 
• Safety Population: The Safety Population will include all patients who were treated with 
at least one dose of the study drug. 
• Intent to Treat (ITT) Population: The ITT Population will include all patients who were 
randomized.   
Efficacy Analyses 
The ITT Population will be used for all efficacy analyses. 
The primary efficacy endpoint will be tested using a 2-sided type I error rate of 0.05 The 
primary outcome variable for the study is the change in total score of the HQ-CT from 
Baseline through Study Completion/Early Withdrawal. 
Statistical inference for the primary endpoint and for the secondary endpoints (change in total 
body-weight, responder rate, PGI-C and PGI-S, TFEQ-R18, and PROMIS Life Satisfaction 
and Positive Affect, PROMIS Physical Activity and Fatigue), will be controlled at an overall 
family wise error rate (alpha) of 0.05, 2-sided.  
For continuous endpoints, number of observations, mean, standard deviation (SD), median, 
minimum, and maximum, will be presented as descriptive statistics. For inferential statistics, 
analysis of covariance (ANCOVA) with the baseline value and randomization strata (growth 
hormone treatment) as covariates. 
For categorical endpoints, the number of observations, frequency counts and percentages will 
be presented as descriptive statistics. Fisher’s exact test will be used for inferential statistics.  
Safety Analyses 
The Safety Population will be used for all safety assessments. 
All safety assessments will be descriptive and no inferential statistics are planned. All data 
listings will be provided for protocol specified safety data. The Medical Dictionary for 
Regulatory Activities (MedDRA; Version 20.0 or higher) will be used to classify all adverse 
events with respect to system organ class and preferred term. Adverse event summaries will 
include only TEAEs by treatment group. All clinical laboratory findings and vital signs will 
be summarized for all patients in the safety population for observed values and change from

baseline. Shifts from baseline according to normal range criteria will also be presented for all 
patients in the safety population. Prior medication and concomitant medications will be 
reported in the data listings.   
Statistical analyses will be performed using SAS® (Version 9.3 or higher, SAS Institute Inc.). 
Pharmacokinetic Analyses   
Exploratory analyses of dose (exposure)-response relationship will be performed. Further 
population PK approach may be used for PK parameter calculations, as appropriate. 
Missing Data 
For efficacy measures, missing data points may be imputed using Jump to Reference as a 
conservative method.  For safety data, there will be no imputation of missing data, and the 
safety assessments will be conducted based on the observed data.

INTRODUCTION 
Data presented in this section include overviews from the nonclinical and clinical published 
literature that report on various other formulations of cannabidiol (CBD) (primarily plant-based).  
Analogous studies have not been completed for Cannabidiol Oral Solution, the non-plant-based 
CBD to be investigated in this study. 
There is evidence that CBD may be effective in anxiety, epilepsy, chemotherapy-induced 
peripheral neuropathy, glioblastoma, addiction and drug dependency, post-traumatic stress 
disorder, weight-loss, and appetite regulation. CBD’s effects on appetite, weight regulation, and 
anxiety are of interest to patients with Prader-Willi Syndrome (PWS), the focus of this 
investigation. 
In addition, the unmet medical needs of Prader-Willi Syndrome as well as the rationale for the 
development of Cannabidiol Oral Solution for the treatment of hyperphagia and obesity in this 
syndrome will be presented (See Section 1.4).   
Please see the Investigator’s Brochure (IB) for more information. 
1.1. 
Cannabidiol 
Cannabidiol is the second most abundant cannabinoid found in the cannabis plant and is highly 
physiologically relevant without the psychoactive sequelae (Pertwee, 2008). In contrast, Δ9-
tetrahydrocannabinol (Δ9-THC) is the most prevalent and principal psychoactive constituent of 
cannabis (Pertwee, 2008).   
Insys Development Company, Inc. (hereafter referred to as the Sponsor) manufactures a 
synthetic pharmaceutical grade CBD drug substance. It is manufactured in a 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). The active pharmaceutical ingredient is ≥99.5% pure (Sponsor internal 
analysis), can be consistently produced without the concern for contaminants of other 
cannabinoids, is formulated with medium chain triglycerides (MCT) without alcohol specifically 
for pediatric use, and will provide CBD to responsibly investigate the treatment of Prader-Willi 
Syndrome (PWS).  
Cannabis was extensively used as a medicine throughout the developed world in the 19th 
century. However, interest as a medicine declined as cannabis became the most widely used 
illicit recreational drug in the 20th century (Robson, 2014). Since the isolation and elucidation of 
the structure of the main active constituent of cannabis, THC, (Gaoni and Mechoulam, 1964) a 
large number of published articles have investigated its chemistry, biochemistry, pharmacology, 
and clinical effects. The effects of cannabis are not due to THC alone. At least one constituent, 
CBD, was found to have significant pharmacological effects on its own, some of which may 
modify the metabolism and effects of THC (Karniol at al., 1974; Jaeger et al., 1996).   
The endogenous endocannabioid system was first described in the 1990’s as the primary targets 
of THC were sought (Mechoulam and Parker, 2013). Studies in animals have demonstrated an 
effect of CBD on appetite, food consumption, and reward system, from sugar intake felt to 
interact with the endogenous endocannabinoid system’s effects on these activities (Silveira Filho 
and Tufik, 1981; Parsons and Hurd, 2015; Edwards and Abizaid, 2016). In addition, CBD has

24 
been observed to have anxiolytic and anti-psychotic properties, two comorbidities that are highly 
prevalent in patients with PWS (Whitman and Accardo, 1987; Crippa et al., 2010). Taken 
together, CBD may have an impact on both the hyperphagia-related disorders and subsequent 
obesity related to PWS. 
1.1.1. 
Mechanism of Action 
The mode of action of CBD is not fully understood.  While THC is a strong agonist of the 
endogenous cannabinoid receptors 1 (CB1) and 2 (CB2), CBD has only a low-affinity for these 
receptors and is believed to be a non-competitive antagonist/inverse agonist to them both 
(Pertwee, 2008; McPartland, 2015; Laprairie et al., 2015). Instead, CBD has been shown to have 
activities at several other biologically relevant receptors in the brain. For instance, it stimulates 
the vanilloid receptor type 1 (Bisogno et al., 2001) and modulates, without antagonism, both µ- 
and δ-opioid receptors (Kathmann et al., 2006). In addition, CBD has been shown to effect 
bidirectional regulation of intracellular calcium homeostasis via the mitochondrial 
sodium/calcium exchanger (Ryan et al., 2009), have agonistic properties at 5-hydroxytryptamine 
1a (5-HT1a) receptors (Russo et al., 2005), and enhancing endogenous adenosine levels in the 
central nervous system (CNS) by reducing adenosine re-uptake leading to increased activity at 
the adenosine A2a receptor (Carrier et al., 2006; Jones et al., 2012). 
These activities have translated to demonstration of anxiolytic effects in animals (Campos et al., 
2013; Gomes et al., 2013) through activation of the 5-HT1a receptors and followed with 
supportive observations in some human studies (Bergamaschi et al., 2011a; Crippa et al., 2011; 
Almeida et al., 2013). In addition, several investigations have outlined how CBD can affect the 
endogenous cholinergic-dopaminergic reward system suggested by decreases in cue-craving and 
increase in threshold for opioid self-administration (Parsons and Hurd, 2015; Prud'homme et al., 
2015).   
1.1.2. 
Metabolism and Potential Drug Interactions 
The major biotransformation pathway for CBD is similar to that of other cannabinoids and 
mediated by hydroxylation by cytochrome P450 (CYP) proteins (Harvey et al., 1991). 
Cannabidiol is metabolized primarily in the liver by CYP3A4 and to a lesser extent by 
CYP2C19.   
Its interactions with human drug metabolizing enzymes (as a substrate, inhibitor, or inducer) 
were recently reviewed (Stout and Cimino, 2014; Bergamaschi et al, 2011b). Specifically, CBD 
inhibits CYP3A4, CYP3A5, CYP2D6, and CYP1A1 in vitro (Johannessen and Landmark, 2010; 
Yamaori et al., 2010, 2011a, 2011b;). It also appears to inhibit CYP2C9 (Yamaori et al., 2012) 
and the transport protein P-glycoprotein (Holland et al., 2006; Zhu et al., 2006).      
Further details may be found in the IB. 
1.2. 
Nonclinical Experience  
1.2.1. 
Safety 
In a nonclinical setting, single-dose toxicology studies of CBD reveal a relatively safe toxicology 
profile except at very high doses of the drug substance. Repeated dose toxicology studies

highlight a potential impact of CBD on spermatogenesis, follicle-stimulating hormone levels, 
and a subset of immune responses. Full detail of these results may be found in the IB. 
1.2.2. 
Efficacy 
There are no prior clinical studies investigating the potential efficacy of cannabidiol in patients 
with Prader-Willi Syndrome. Please refer to Section 1.4 for review of potential clinical efficacy 
of cannabidiol from studies in different patient populations. The following is a review of non-
clinical data on the use of cannabidiol on food and water intake in animals. 
Eight preclinical studies examined the effect of CBD on food and water intake and/or weight 
gain. However, the results were often conflicting based on the dose, dosing regimen, endpoints 
and analyses conducted and suggest a lack of acute effect following starvation, but do suggest a 
sustained effect against hyperphagia-related food intake. 
1.2.2.1. 
Single Dose Regimens 
Sofia and Knobloch (1976) looked at the effect of a single dose of CBD (50 mg/kg) given to rats 
intraperitoneally (IP) on food and water intake when food plus water, food plus 5% sucrose, or 
food + 20% sucrose was given. They followed the animals out for 6 days after the injections. 
They found that CBD, as well as THC and cannabinol (CBN), led to decreased food intake 
which was maximal the first day and returned to normal by the 5th day. They also noted that the 
effect was greater for food than for the sucrose solutions. They concluded that CBD led to a 
preference for sweet calories and that CBD led to decreased intake. This effect decreased daily 
until it was no longer present, approximately 3-5 days after treatment. 
Silveira Filho and Tufik (1981) noted that intake of food by albino rats was decreased after 
treatment with 30 mg/kg CBD compared with control rats. 
Riedel et al. (2009) studied the effects of a synthetic CB1 antagonist, a phytocannabinoid 
(THCV) that acts as a CB1 antagonist, an extract rich in THCV, CBD alone, and a combination 
of the extract with CBD in both a single-dose regimen as well as a multiple-dose regimen (over 
4 days). In the single dose regimen, mice were administered the above in either a fasted state 
(maximum 24 hours) or a non-fasted state after which they were allowed free access to food. As 
expected, the CB1 antagonists led to a decrease in food uptake and weight loss on the day post 
treatment. An extract rich in THCV did not result in a decline in weight that was thought to be 
due to the small amounts of THC present. While CBD alone at a low dose of 10 mg/kg induced a 
small although non-significant reduction in weight gain, in combination with the THCV-rich 
extract gave a significant suppression of time spent in the food zone. The multiple treatments 
over 4 days gave the same results. 
Scopinho et al. (2011) treated Wistar rats that had free access to food or animals that had been 
fasted for 18 hours with a single IP injection of 1, 10, or 20 mg/kg CBD. After 30 minutes, the 
rats were provided food. While CBD alone had no effect on food intake, CBD was able to 
prevent the hyperphagia seen in rats that had also been treated with agonists to CB1 or 5-HT1A 
receptors. 
Farrimond et al. (2012) treated rats with CBD (doses 0.04 mg/kg, 0.44 mg/kg, 4.4 mg/kg) and 
tested later for food intake. Only doses of 4.4 mg/kg demonstrated a statistically significant 
decrease in cumulative food intake when measured over 1-4 hours after treatment.

1.2.2.2. 
Multiple Dose Regimens 
Ignatowska-Jankowska et al. (2011) treated male Wistar rats at an age when body weight is 
rapidly increasing with IP injections at doses of 2.5 mg and 5 mg/kg/day for 14 consecutive days. 
The diet provided was standard ad lib rodent chow without prior fasting. Both CBD doses 
produced significant decreases in body weight gain, with the effect produced by the 5 mg/kg 
dose being more pronounced. This effect on weight was blocked, however, by a selective CB2 
antagonist, raising the possibility of more peripheral, non-CNS mechanism.  
Wierucka-Rybak et al. (2014) reported a study where CBD alone or in combination with leptin 
were administered intraperitoneally to Wistar rats for 3 consecutive days and maintained on 
either a high-fat diet or free choice diet consisting of high-sucrose and normal rat chow. 
Interestingly, while CBD seemed to decrease food intake on rats feed high fat diet or standard 
chow, there did not seem to be corresponding decrease in weight after the 4 days of the study. 
Rhesus monkeys treated with oral CBD for 90 consecutive days (30-300 mg/kg/day; 4 
monkeys/sex/dose) to observe toxicities demonstrated a relative dose-dependent decrease in 
weight gain. As it was reported as an observation, it did not merit comment by the authors 
(Rosenkrantz et al., 1981).  
While animal models provide seemingly inconsistent results on the effect of CBD on food intake 
and weight, they nonetheless suggest a potential non-acute effect on appetite and overall food 
consumption. This likely indicates, more than anything, the complex interaction between the 
endocanniboid system with appetite regulation (via the leptin and ghrelin), the endogenous 
reward system mediated by the cholinergic-serotinergic pathway, and metabolic regulation. The 
observation that some studies have demonstrated that CBD up to 80-100 mg/kg had no acute 
(within 24 hours) effect on food consumption in mice and rats, but did so in longer test periods 
provides support for the length of the current study of 12 weeks.

Clinical Experience 
Overall, over 100 patients have been treated with Cannabidiol Oral Solution, many for over 48 
weeks, ranging in age from 1-51 years and was generally well-tolerated. A summary of the 
clinical experience is summarized below in Table 2. 
A Phase 1/2 study to assess the pharmacokinetics and safety of multiple doses (10 mg/kg/day, 
20 mg/kg/day, and 40 mg/kg/day) of pharmaceutical Cannabidiol Oral Solution in pediatric 
subjects with treatment-resistant seizure disorders was conducted by the Sponsor (Protocol 
INS011-14-029). This study has been completed and the data were presented. In addition, a long-
term safety study (Protocol INS011-14-030) for subjects who enrolled in the PK study above 
recently completed. 
An open-label study of Cannabidiol Oral Solution (20 mg/kg/day and 40 mg/kg/day) in pediatric 
subjects with infantile spasms refractory to adrenocorticotropic hormone (ACTH) and vigabatrin

Pharmacokinetics 
INS011-14-029 is a completed Phase 1/2 study assessing the PK and safety of multiple doses of 
pharmaceutical CBD (Cannabidiol Oral Solution, Insys Development Company, Inc.). Each 
cohort of 20 pediatric patients from 1 to 17 years of age was administered 10 mg/kg/day, 20 
mg/kg/day, or 40 mg/kg/day over a period of 10 days. Patients were dosed as inpatients for Days 
1 through 8. Patients were then offered the opportunity to be discharged on Day 8 with 
readmission on Day 10 for a final study assessment on Day 11. Cohort 1 received an earlier 
formulation containing alcohol; Cohorts 2 and 3 received a subsequent alcohol-free, medium 
chain triglyceride (MCT)-containing formulation. The study was designed to have adequate 
representation among three age groups in each dosing cohort: infants (1 to <2 yrs: 5 subjects), 
children (2 to <12 yrs: 9 subjects), and adolescents (12 to <18 yrs: 6 subjects). 
Single oral administration of CBD at 5, 10, 20 mg/kg (half of the full daily dose) resulted in 
mean peak levels of about 59, 111, and 232 ng/mL, respectively. The PK of CBD in different age 
groups was comparable at each dose level. Steady-state seemed to be achieved within 2 to 4 days 
after twice daily doses of 5, 10, 20 mg/kg/day CBD, with typical steady-state peak levels of 
about 120, 214, and 427 ng/mL, respectively.  
A dose proportional increase in CBD exposures on Day 10 was clearly observed in mean Cmax,ss 
and AUCtau, even if two different formulations were used in the study. Accumulation after 
repeated doses was about 2-fold. Plasma levels of 7-OH cannabidiol were generally similar to 
the parent drug. 
The food effect study (Protocol INS011-15-043) demonstrated that when taken within 30 
minutes of the start of a meal, CBD mean AUC and Cmax were significantly higher with a much 
improved (lower) coefficient of variance and a 6-hour shorter median time to maximum 
concentration (Tmax). Thus, there is a recommendation that all doses be administered within 30 
minutes after the start of a meal. 
Insys Study INS011-16-093 examined three different formulations under fed with standard high-
fat diet and/or fasted conditions: sesame-oil based, 100 mg/mL (fed and fasted), MCT-based, 
100mg/mL (fed) and alcohol-containing, 80 mg/mL). An appreciable food effect and lower 
variability were observed with the Cannabidiol Oral Solution (100 mg/mL) in a Sesame Oil 
Formulation, with mean exposures of 6.9-fold and 11.9-fold higher, for AUC0-t and Cmax, 
respectively, relative to the fasted state. All formulations (Sesame Oil, Medium Chain 
Triglyceride, and alcohol-containing) showed similar exposures in the fed state. Mean (SD) 
AUC0-inf (h*ng/mL) in the fed condition was: 4450 (1130) for Sesame Oil based, 4360 (933) for 
MCT-based, and 4980 (2110) for alcohol-containing. The %CV was 25.3, 21.4, and 42.3 for 
Sesame-Oil based, MCT-based, and alcohol-containing, respectively. 
As a comparison, mean peak and total exposures in all age groups (Protocol INS011-14-029) on 
Day 10 were within 16 to 36% to dose-adjusted exposures in fed adults (Protocol INS011-15-

043). Thus, similar PK parameters are expected to operate over this study’s age range of 8-17 
years of age. 
1.3.2. 
Overview of Safety 
Clinical data described in the following sections were collected following administration of 
various extracts of CBD as oral solutions or solid formulations. 
Clinical studies in various human populations indicate that CBD has a favorable side-effect 
profile. Doses as high as 1500 mg were well tolerated (Zuardi et al., 1995). 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. (2011b) recently reviewed the safety 
of CBD in humans examined in 221 subjects across 21 studies. As detailed in the IB, no 
significant safety issues were reported. 
Regarding doses of CBD that have been examined in other studies, daily doses of 200 to 300 mg 
CBD (or potentially more) may be safe (Cunha et al., 1980; Gloss and Vickery, 2014). Clinical 
evaluation and therapeutic ranges of CBD doses have been reported to be between 10 and 
1500 mg/day, with the majority of reports evaluating doses in the 300 to 600 mg/day CBD range.  
Furthermore, between 300 and 1500 mg have been used in humans without toxicity or SAEs 
(Consroe et al., 1991; Zuardi et al., 1993, 1995; Borgwardt et al., 2008).    
In Study INS011-14-029 and the subsequent extension study, INS011-14-030, some patients 
received over 3000 mg/day for several months without toxicity or SAE. 
1.3.3. 
Clinical Safety Data 
The following specific examples detail selected studies of the safety of CBD use in humans: 
• Daily dosing of 10 mg/kg CBD was evaluated in a study of 15 subjects diagnosed with 
Huntington's disease (Consroe et al., 1991). Only 15 abnormal clinical laboratory values 
were associated with CBD treatment; these were largely limited to 4 subjects and 
exhibited no obvious pattern. No significant or clinical differences in CBD were observed 
in a cannabis-specific side-effect inventory. 
• Chronic oral administration of 10 mg CBD 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 subjects (Cunha et al., 1980).  
• Oral administration of CBD 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 (Cunha et al., 1980; Gloss and Vickery, 2014). 
• Administration of single and repeated doses of CBD 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 (Gong et al., 1984).  
• Three subjects with treatment-resistant schizophrenia have been dosed with 40 to 1280 
mg/day of CBD for up to 4 weeks without reporting side-effects (Zuardi et al., 2006).

• Two subjects diagnosed with bipolar affective disorder did not report adverse effects 
upon receiving 600 to 1200 mg/day of CBD for up to 24 days (Zuardi et al., 2010).     
• Insys recently completed a long-term safety study (INS-011-030, 48 weeks) for pediatric 
subjects who were receiving up to 40 mg/kg/day (maximum dose given was 3200 
mg/day) in the Phase 1/2 PK study (Protocol INS011-14-029) and these doses were 
generally well tolerated. 
• There is currently an expanded access program ongoing for the pediatric patients who 
completed the long-term safety study (INS-011-030) and wished to continue on CBD 
therapy. 
In addition to the references cited above, there are recently published studies of CBD treatment 
of refractory epilepsy.  
In an open label study of Epidiolex® (a plant-derived purified CBD), 214 patients suffering from 
different refractory epilepsies were enrolled between January 15, 2014, and January 15, 2015 
(Devinsky et al., 2016). Patients were given oral cannabidiol at 2-5 mg/kg per day, up-titrated 
until intolerance or to a maximum dose of 25 mg/kg or 50 mg/kg per day (dependent on study 
site), for a 12-week treatment period. Titration to a maximum dose of 50 mg/kg per day was 
done in 48 (30%) patients, 23 of whom received a dose of more than 25 mg/kg per day during 
the 12-week treatment period. Of the 214 enrolled patients, 162 (76%) patients who had at least 
12 weeks of follow-up after the first dose of cannabidiol were included in the safety and 
tolerability analysis, 137 (64%) patients were included in the efficacy analysis. 
The most common adverse events reported (in more than 10% of patients) were somnolence 
(n=41, 25%), decreased appetite (n=31, 19%), diarrhea (n=31, 19%), fatigue (n=21, 13%), and 
convulsion (n=18, 11%). Five (3%) patients discontinued treatment because of an adverse event. 
Serious adverse events were reported in 48 (30%) patients, including one death-a sudden 
unexpected death in epilepsy regarded as unrelated to study drug; 20 (12%) patients had severe 
adverse events possibly related to cannabidiol use, the most common of which was status 
epilepticus (n=9 [6%]). 
In a Phase 3 study, 171 patients aged 2 to 55 years with a confirmed diagnosis of drug-resistant 
Lennox–Gastaut Syndrome (LGS) currently uncontrolled on one or more concomitant AEDs 
were randomized into two treatment arms, Epidiolex® 20 mg/kg/day (n=86) or placebo (n=85), 
for a 14-week treatment period (Thiele et al., 2016). Epidiolex® or placebo was added to current 
AED treatment regimens. On average, patients were taking approximately 3 AEDs, having 
previously tried and failed an average of 6 other AEDs. The average age of patients was 15 
years. Epidiolex® was generally well tolerated in this trial. Overall, 86% of all Epidiolex® 
patients experienced an adverse event compared with 69% of patients on placebo. The most 
common adverse events (occurring in greater than 10% of Epidiolex®-treated patients) were: 
diarrhea, somnolence, decreased appetite, pyrexia, and vomiting. Twenty patients on 
Epidiolex® experienced a serious adverse event (nine of which were deemed treatment related) 
compared with four patients on placebo (one of which was deemed treatment related). Twelve 
patients on Epidiolex® discontinued treatment due to adverse events compared with one patient 
on placebo. There was one death in the Epidiolex® group, which was considered unrelated to 
treatment.

In another Phase 3 study, 120 patients aged 2 to 18 years with Dravet Syndrome were 
randomized into two treatment arms, Epidiolex® 20 mg/kg/day (n=61) and placebo (n=59), for a 
14-week treatment period (Devinsky et al., 2017). Epidiolex® or placebo was added to current 
AED treatment regimens. On average, patients were taking approximately three AEDs, having 
previously tried and failed an average of more than four other AEDs. The average age of trial 
participants was 10 years and 30 percent of patients were less than 6 years of age. Epidiolex® 
was generally well tolerated in this study. The most common adverse events (AEs) (occurring in 
greater than ten percent of Epidiolex®-treated patients) were: somnolence, diarrhea, decreased 
appetite, fatigue, pyrexia, vomiting, lethargy, upper respiratory tract infection, and convulsion.  
Ten patients receiving Epidiolex® experienced a serious AE compared with three patients 
receiving placebo. None of these events led to withdrawal from the study and none were 
considered related to the study treatment. 
In Study INS011-14-029, the most common adverse events included somnolence (21.3%), 
diarrhea (16.4%), anemia (18%), psychomotor hyperactivity (8.2%), and flatulence (8.2%).  
Somnolence may have been related to the concomitant administration with the anti-epileptic, 
clobazam, that resulted in increased plasma levels of clobazam due to a unique drug-drug 
interaction. The somnolence improved following dose adjustments. Somnolence was observed in 
only 3.3% of study subjects who were not taking clobazam. In addition, three serious adverse 
events were observed following administration of drug (three were observed after screening but 
before dosing). The first involved the development of a thrombus associated with a peripherally 
inserted central catheter (PICC) line in an infant. The thrombus resolved with treatment without 
any untoward effects. The second involved an apneic episode felt to be related to 
gastroesophageal reflux disease (GIRD) also in an infant. Neither of these SAEs were deemed by 
the investigator to be related to the drug. The third SAE consisted of a drug eruption following 
the final dose of the study that self-resolved without intervention. 
In the long-term safety study, INS014-030, 52 patients continued treatment for approximately 
48 weeks at doses ranging from 10 mg/kg/day to 40 mg/kg/day. Cannabidiol Oral Solution was 
generally safe and well-tolerated. The most frequently reported AEs were seizure, upper 
respiratory tract infection, anemia, diarrhea, pyrexia, somnolence, aggression, nasopharyngitis, 
and otitis media; anemia and somnolence were considered related to study drug. Seventeen 
subjects experienced serious TEAEs; the most frequently reported serious TEAEs were seizure, 
status epilepticus, and mental status changes (all considered unrelated to study drug). These 
events may have been consistent with the subjects’ underlying disease and seizure history. One 
subject died during the study due to systemic sepsis that was considered unrelated to 
investigational product. Dose reductions occurred for 26.9% of the patients; primarily at the 
40 mg/kg/day dose (9/20 patients, 45.0%).   
In summary, the safety data to date suggest that cannabidiol can be safely administered to and 
tolerated by medically complex pediatric and adult patients at doses up to 40 mg/kg/day for 
extended periods of time (currently over 48 weeks). Despite the confounding co-administration 
of clobazam in the majority of cases of observed somnolence, cannabidiol should be carefully 
monitored in patients with significant respiratory comorbidities, such as those that occur in 
patients with Prader-Willi Syndrome.

1.4. 
Prader-Willi Syndrome 
Prader-Willi Syndrome (PWS), first described in 1956, is a multifaceted developmental disorder 
and the most common genetic syndrome associated with obesity (Gunay-Aygun et al., 1997; 
McAllister and Whittington, 2011). It is caused by the absent expression of paternally-inherited 
genes in the PWS region on 15q11-q13 (Ledbetter et al., 1981). While it presents with 
generalized hypotonia and developmental delay in infancy, PWS then manifests with 
uncontrollable appetite, hyperphagia, and excessive weight gain leading to severe obesity 
(Grechi et al., 2012).  
Clinically, PWS patients suffer a complex pattern of physical, behavioral, endocrine, and 
intellectual deficiencies. Endocrine abnormalities lead to hypogonadism and short stature. In 
particular, growth hormone deficiency is reported to occur in 40% to 100% of the population 
(Griggs et al., 2015) and is commonly treated with growth hormone (Angulo et al., 2015). 
Behavioral disorders include obsessive compulsive behaviors such as skin picking, hoarding, re-
doing, and repetitive speech (Griggs et al., 2015).  
However, it is the appetite behavior classified as hyperphagia in Prader-Willi Syndrome that is 
the most life threatening (Dykens et al., 2007; Griggs et al., 2015) and until recently, no patient 
lived over the age of 50 due to morbid obesity and its related complications (Aycan et al., 2014). 
The mortality rate in patients with PWS is six times higher than patients with other intellectual 
disabilities (Einfeld and Kavanagh, 2006) and mortality in patients not treated with growth 
hormone was estimated to be 3% per year between the ages of 6 and 56 compared to the general 
population mortality of 0.13% below 55 years. Mortality in Prader-Willi Syndrome below 
5 years of age has not been determined (Eiholzer, 2005).   
Hyperphagic behaviors can also be dangerous in persons who are not obese, with increased risks 
of death due to choking while sneaking food, and gastric perforations after consuming more food 
than usual (Dykens et al., 2007). Approximately 8% of deaths in individuals with PWS are 
reported due to the choking, especially on hot dogs (Stevenson et al., 2007). PWS patients also 
are known to eat discarded (contaminated) food and items that are not for human consumption 
such as pet food, or even non-food items such as paint or paper (Griggs et al., 2015).   
Currently, there are no FDA-approved therapies for the treatment of hyperphagia or obesity in 
patients with PWS. In addition, drugs that have demonstrated efficacy in the past have been 
withdrawn or have significant safety concerns (e.g., rimonabant, beloranib). Therapy consists 
mostly of strict and consistent behavioral controls surrounding eating that prevent independent 
living for adult patients. Recent studies investigating modulation of the endocannabinoid system, 
however, have shown promise.   
The endocannabinoid system appears to be critically involved in the regulation of appetite, body 
weight, metabolism, hypothalamic-pituitary-adrenal axis, and reward brain circuitry (Liu et al., 
2005; Edwards and Abizaid, 2016). Endocannabinoid receptor CB1, is widely expressed in the 
central nervous system, autonomic gastric vagus nerve endings of the peripheral nervous system, 
and other key cells involved in body energy metabolism, including adipocytes, hepatocytes, and 
myocytes (Bensaid et al., 2003; Liu et al., 2005; Osei-Hyiaman et al., 2008). In clinical studies, 
compounds with endocannabinoid effects (fenfluramine, rimonabant) have shown significant 
effects on weight and appetite suppression (Pinder et al., 1975; Despres et al., 2005; Pi-Sunyer et 
al., 2006). These effects on appetite also occurred in 19% of epilepsy patients treated with

Epidiolex® (i.e., cannabidiol extracted from the cannabis plant) during an open-access program 
for patients with pediatric seizure disorder (Devinsky et al., 2016). Because of the well-
characterized orexigenic activity of THC (a strong CB1 agonist), the CB1 antagonist, 
rimonabant, was studied and found to be effective in treating obesity in adults without PWS (Pi-
Sunyer et al., 2006). Both fenfluramine and rimonabant were subsequently withdrawn from the 
market, however, due to unacceptable side effects (McCann et al., 1997).  
CBD is a low-affinity antagonist of CB1, but it may also modulate CB1 receptor signaling 
through its inhibition of the metabolism of the endogenous cannabinoid, anandamide (Ibeas Bih 
et al., 2015; Laprairie et al., 2015). As for appetite, CBD has been shown to decrease food intake 
in rats under stressful conditions and reduce ad lib intake of high-sugar feed when compared to 
vehicle-treated controls (Silveira Filho and Tufik, 1980). In addition, CBD has been shown to 
diminish daily food consumption without affecting daily water intake (Wierucka-Rybak et al., 
2014) as well as inhibited hyperphagia induced by CB1 receptor or 5-hydroxytryptamine (5-
HT1A) serotonin receptor agonists suggesting a role for CBD as a regulator of food intake. 
Perhaps just as importantly, CBD decreases cue-induced craving and reduces the reward induced 
by drugs of abuse by modulating the cholanergic-dopaminergic pathway that may drive such 
behaviors in PWS patients (Von Deneen et al., 2009; Hurd et al., 2015; Parsons and Hurd, 2015).   
Thus, CBD may have potential to address the main medical problems associated with Prader-
Willi Syndrome patients leading to obesity and related mortality. Insys Development Company, 
Inc. (Insys) is manufacturing a pharmaceutical grade synthetic cannabidiol formulation 
(Cannabidiol Oral Solution) to be advanced into clinical development for the treatment of 
hyperphagia behaviors and obesity in patients with Prader-Willi Syndrome.

Dose Selection Rationale 
Doses up to 40 mg/kg/day were administered in the Phase 1/2 PK study (Protocol INS011-14-
029) and the long-term safety study (Protocol INS011-14-030). The maximum dose given was 
3200 mg/day in an adolescent. These doses were generally well tolerated even without titration. 
Because the Prader-Willi patients enrolled in this study will be obese and there were concerns 
that distribution to fat would decrease the effective dose in these subjects, the maximum 
tolerated dose identified in the previous PK and safety study will be given. To maximize 
tolerability, a one-week titration period is included in this study (initial dose of 20 mg/kg/day for 
3 days, followed by 30 mg/kg/day for 3 days, and then 40 mg/kg/day starting on Day 7 and 
continuing through the duration of the study). 
1.6. 
Summary of Potential Risks and Benefits 
 As reviewed in Sections 1.2 and 1.3, numerous nonclinical and clinical studies have examined 
other formulations of CBD. Several areas of potential concern have been identified with the use 
of CBD, especially in nonclinical studies. These include:   
• Competitive binding of CYP proteins (thus, an impact on drug metabolism in the liver). 
Cannabidiol is metabolized predominantly by CYP3A4 and CYP 2C19.  Cannabidiol 
may inhibit these two isozymes, as well as having small effects on CYP3A5, CYP2D6, 
CYP1A1, and CYP2C9. 
• Potential downregulation of immune responses involving the T, B, T-helper, and T 
cytotoxic subsets of leukocytes and/or those dependent on IL-2 or IFN-γ.

Based on recent studies of cannabinoid administration in humans, controlled CBD may be safe in 
humans and animals. While further studies are needed to clarify these reported in vitro and in 
vivo side-effects (Braut-Boucher et al., 1986), no infection-related events have been reported in 
recent studies in the pediatric seizure population. 
The inclusion/exclusion criteria, concomitant medication guidelines, and safety monitoring (AEs, 
clinical laboratory, vital signs, ECG, and physical examination assessments) planned for this 
study are intended to minimize these potential safety risks.   
Criteria for removal of subjects from the study and stopping rules will dictate discontinuation of 
subject participation should a safety issue arise (see Section 3.3 and Section 3.6, respectively).  
The appetite behavior classified as hyperphagia in Prader-Willi Syndrome is the most life 
threatening (Dykens et al., 2007; Griggs et al., 2015) and until recently, no patient lived over the 
age of 50 years due to morbid obesity and the related complications (Aycan et al., 2014). The 
mortality rate in patients with PWS is six times higher than patients with other intellectual 
disabilities (Einfeld et al., 2006) and mortality in patients not treated with growth hormone was 
estimated to be 3% per year between the ages of 6 and 56 years compared to the general 
population mortality of 0.13% below 55 years; mortality in Prader-Willi Syndrome below 
5 years of age has not been determined (Eiholzer, 2005).  
Hyperphagic behaviors can also be dangerous in persons who are not obese, with increased risks 
of death due to choking while sneaking food, and gastric perforations after consuming more food 
than usual (Dykens et al., 2007). Approximately 8% of deaths in individuals with PWS was 
reported due to the choking, especially on hot dogs (Stevenson et al., 2007). Prader-Willi 
Syndrome patients also are known to eat discarded (contaminated) food and items that are not for 
human consumption such as pet food, or even non-food items such as paint or paper (Griggs et 
al., 2015). 
Subjects with PWS continue to experience a significant unmet medical need, especially when it 
comes to hyperphagia behavior and obesity. There are no approved drugs currently to treat these 
behaviors. Fenfluramine demonstrated significant efficacy in Prader-Willi Syndrome patients but 
was removed from the market due to cardiac valve concerns. Rimonabant was approved in the 
EU for obesity and a trial was ongoing in Prader-Willi Syndrome. However, the drug was never 
approved in the US and removed from the market in the EU due to significant psychiatric side 
effects. A trial in PWS, while demonstrating a trend for efficacy was terminated early for safety 
concerns. Currently, Zafgen’s product Beloranib demonstrated significant positive effects on 
weight loss and hyperphagia behavior in patients with Prader-Willi syndrome but is currently on 
hold due to two deaths that were thought to be caused by thrombotic events. Orlistant, locaserin, 
Qsymia, and Contrave have been approved for obesity but not studied in the Prader-Willi 
Syndrome population. Therefore, there continues to be a high unmet need for an efficacious and 
safe treatment for this population.  
Cannabidiol has been safely administered to over 300 medically complex children and was 
generally well-tolerated. The adverse events recorded do not correspond to those encountered by 
previous trials in patients with Prader-Willi syndrome. The anxiolytic effects of CBD and its 
indirect effect on the CB1 receptor suggest an improved side effect profile in this population. 
In conclusion, there is both pre-clinical and clinical evidence that affecting the endocannabinoid 
system with cannabidiols, including cannabidiol, may demonstrate a clinically relevant effect on

the hyperphagia behaviors as well as lead to weight loss in patients with Prader-Willi Syndrome. 
Insys believes that due to the safety and tolerability of cannabidiol demonstrated by the data 
available in the literature and collected by the sponsor, and the life-threatening obesity in Prader-
Willi Syndrome, the demonstration of efficacy and safety of Cannabidiol Oral Solution in this 
population will be a valuable option to treat these patients.

INVESTIGATIONAL PLAN 
3.1. 
Overall Study Design 
This is a double-blind, randomized, placebo-controlled, Phase 2 clinical trial in patients 
diagnosed with Prader-Willi Syndrome. Patients will receive either Cannabidiol Oral Solution 
(40 mg/kg/day) or placebo with patients randomized in a 1:1 ratio. Randomization will be 
stratified according to use of growth hormone treatment.  
Approximately 66 male and female patients aged 8 to 17 years, inclusive, with a genetically 
confirmed diagnosis of Prader-Willi Syndrome will be enrolled in the study.  
The study will consist of the following six periods: 
• Screening Period (2 weeks) 
• Placebo Lead-In Period (2 weeks) 
• Titration Period (1 week) 
• Maintenance Period (12 weeks) 
• Taper Period (1 week) 
• Follow-Up Period (1 week) 
Patients who meet entry criteria will be assigned to a 2-week single-blind Placebo Lead-In 
Period. Following the placebo single-blind lead-in period, patients will be randomly assigned to 
receive double-blind treatment with either Cannabidiol Oral Solution treatment at a dose of 
40 mg/kg/day or matching placebo divided twice daily with standard meal (a 1-week Titration 
Period followed by a 12-week Maintenance Period). During the Titration Period, Cannabidiol 
Oral Solution will be titrated as follows: Days 1-3: 20 mg/kg/day, Days 4-6: 30 mg/kg/day, Day 
7: 40 mg/kg/day. The Investigator or designee will call on Day 3 and Day 6 to determine if the 
patient’s dose may be titrated to the next dose level.  If the Investigator determines that the 
patient is unable to tolerate the higher dose, the patient should be withdrawn from the study.   
During the Maintenance Period, patients may have their dose of blinded study medication 
adjusted down to 30 mg/kg/day at the discretion of the Investigator or qualified designee based 
on the patient’s tolerability. 
After completion of the study, patients will be offered an opportunity to enroll into an open-
label, long-term safety study. Patients who do not elect to enroll in the long-term safety study 
will be titrated off the study drug over 7 days according to the following schedule: 40 mg/kg/day 
to 30 mg/kg/day for 3 days, to 20 mg/kg/day for 3 days, and then discontinue the drug on Day 7. 
A final safety follow-up phone call will be placed 2 weeks after study completion (Visit 10) for 
patients who do not elect to continue into the long-term safety study and whose AEs have not 
resolved prior to the last visit.  
The study design and patient progression through the study is outlined in Figure 1. 
All screening, efficacy, and safety evaluations will be performed according to the schedule of 
assessments summarized in Table 1.

41 
• Changes in medical status or medical condition of the patient such that the Investigator 
believes that patient safety will be compromised or that it would be in the best interest of 
the patient to stop treatment.  
• Pregnancy.  
• Relevant non-compliance with the protocol. 
• Any use of marijuana, confirmed by a positive drug screen for THC. 
In the event of a patient’s withdrawal, the Investigator will promptly notify the sponsor. Every 
effort will be made to complete the end-of-study assessments. 
Should any patient choose to withdraw early from the study, they will be advised of the safety 
precautions to be taken and will be followed until resolution of any AE or until the unresolved 
AEs are judged by the investigator to have stabilized. 
Patients who are withdrawn from the study may be replaced at the discretion of the Sponsor. 
3.4. 
Premature Patient Withdrawal 
All patients will be advised that they are free to withdraw from participation in this study at any 
time, for any reason, and without prejudice. Every reasonable attempt should be made by the 
investigator to keep patients in the study. However, patients must be withdrawn from the study if 
they withdraw consent to participate. Investigators must attempt to contact patients who fail to 
attend scheduled visits by telephone or other means to exclude the possibility of an AE being the 
cause of withdrawal. Should this be the cause, the AE must be documented, reported, and 
followed as described in Section 6.2.6. The sponsor reserves the right to request the withdrawal 
of a patient due to protocol violations (i.e., terminating investigational product treatment and/or 
procedures) or other reasons. 
The investigator also has the right to withdraw patients from the study at any time for lack of 
therapeutic effect that is intolerable or otherwise unacceptable to the patient, for intolerable or 
unacceptable AEs, intercurrent illness, noncompliance with study procedures, administrative 
reasons, or in the investigator’s opinion, to protect the patient’s best interest. 
If a patient is withdrawn before completing the study, the reason for withdrawal and the date of 
discontinuation will be recorded on the appropriate case report form (CRF). Whenever possible 
and reasonable, the evaluations that were to be conducted at the completion of the study should 
be performed at the time of premature discontinuation. 
3.5. 
Dose Adjustment Criteria 
During the Maintenance Period, patients may have their dose of blinded study medication 
adjusted down to 30 mg/kg/day at the discretion of the Investigator or qualified designee based 
on the patient’s tolerability. If the lower dose is not tolerated, the drug will be discontinued and 
the patient will be withdrawn from the study. 
3.6. 
 Stopping Rules 
The Investigator reserves the right to terminate the study in the interest of patient safety and 
welfare. The Sponsor reserves the right to terminate the study at any time for administrative 
reasons. Patients will also be discontinued when their liver enzymes and serum bilirubin reach:

Treatments Administered 
4.1.1. 
Screening Period 
No study medication will be provided in the Screening Phase. 
4.1.2. 
Placebo Lead-In Period 
Patients will be required to complete a single blind placebo lead-in period. Patients will receive a 
matching placebo of Cannabidiol Oral Solution 40 mg/kg/day divided into twice daily dose with 
standard meal for 2 weeks. 
4.1.3. 
Titration Period 
At Visit 3 (Baseline), eligible patients will enter a 1-week Titration Period and will be 
randomized in a 1:1 ratio to receive Cannabidiol Oral Solution (40 mg/kg/day) or matching 
Placebo twice daily.  
Titration will begin at 20 mg/kg/day divided into twice daily dose with standard meal for 3 days. 
If the 20 mg/kg/day dose of study medication has been well tolerated, patients will increase the 
dose of study medication to 30 mg/kg/day divided into twice daily doses with standard meal for 
3 days. If the 30 mg/kg/day dose of study medication has been well-tolerated, patients will up 
titrate to the maximum dose of 40 mg/kg/day and start the 12-week Maintenance Period.  
If the initial 20 mg/kg/day or the 30/mg/kg/day dose of study medication was NOT 
well-tolerated, patients will be discontinued from the study.  
4.1.4. 
Maintenance Period 
At Visit 4, patients will enter a 12-week Maintenance Period and continue taking Cannabidiol 
Oral Solution or matching placebo divided into twice daily dose with standard meal.   
Patients may have their dose of study medication adjusted down by one dose level on one 
occasion at the discretion of the Investigator, or qualified designee. If the 40 mg/kg/day dose of 
study medication was NOT well tolerated, patients may have their dose of study medication 
adjusted to 30 mg/kg/day. If patients are unable to tolerate the 30 mg/kg/day dose of study 
medication, the drug will be discontinued and the patient will be withdrawn from the study. 
4.1.5. 
Taper Period 
Following the completion of the Maintenance Period (Visit 10), patients will have the option to 
continue treatment in an open-label long-term safety study. Patients who choose to enroll in the 
long-term safety study will not have a follow-up visit. Patients who do not choose to enroll in the 
long-term safety study will taper the dose of study medication according to the following 
schedule: 40 mg/kg/day dose will be reduced to 30 mg/kg/day for three days, then 30 mg/kg/day 
will be reduced to 20 mg/kg/day for three days and then discontinued; 30 mg/kg/day dose will be 
reduced to 20 mg/kg/day for three days and then discontinued.

A follow-up visit call will occur within 2 weeks after study completion. No study medication 
will be provided during this time. 
4.2. 
Identity of Investigational Product 
The active pharmaceutical ingredient (API) in Cannabidiol Oral Solution is a synthetic, 
pharmaceutical grade CBD 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-brown colored solution 
(CBD concentration of 100 mg/mL) filled into a 30 mL amber glass vial. More detailed 
information may be found in the IB.  
4.3. 
Method of Assigning Patients to Treatment Groups 
Following the 2-week Placebo Lead-In Period of the study, patients will be randomized in a 1:1 
ratio, using a web-based randomization system. The randomization will be stratified according to 
growth hormone treatment (yes/no).   
4.4. 
Selection and Timing of Dose for Each Patient 
Patients will receive Cannabidiol Oral Solution or matching placebo twice daily with standard 
meal as described in Section 4.1. The date and time of all investigational product administrations 
will be documented in the CRF. 
4.5. 
Blinding and Unblinding Treatment Assignment 
In the double-blind treatment period of the study, all patients and study personnel involved in the 
conduct of the study, including data management, will be blinded to treatment assignment with 
the exception of a specified unblinded statistical programmer from the sponsor or sponsor’s 
representative who will have access to the randomization codes. The unblinded study personnel 
will not otherwise participate in study procedures or data analysis before unblinding of the study 
data to all study-related personnel. 
Study personnel will endeavor to safeguard the integrity of the study blind to minimize bias in 
the conduct of the study. Treatment unblinding is discouraged if knowledge of the treatment 
assignment will not materially change the planned management of a medical emergency. 
Unblinding will be permitted in a medical emergency that requires immediate knowledge of the 
patient’s treatment assignment. If a medical emergency occurs and unblinding is required, the 
site will contact IXRS for drug assignment. Unblinding should be discussed in advance with the 
sponsor, sponsor’s representative, or medical monitor if possible. For emergency unblinding, 
study personnel will contact the sponsor or sponsor’s representative. If the investigator is not 
able to discuss treatment unblinding in advance, the sponsor or sponsor’s representative must be 
notified, or medical monitor as soon as possible about the unblinding incident without revealing 
the patient’s treatment assignment. The investigator or designee must record the date and reason 
for study unblinding in the source document for that patient. In all cases that are not 
emergencies, the investigator must discuss the event with the sponsor, sponsor’s representative, 
and/or medical monitor prior to unblinding the patient’s treatment assignment.

If the treatment assignment is unblinded for an individual patient, study personnel will be 
notified of that patient’s treatment assignment without unblinding of the treatment assignments 
for the remaining patients in the study. Thus, the overall study blind will not be compromised. If 
a patient’s treatment assignment is unblinded, he or she may or may not be asked to withdraw 
from the study. The investigator will make this decision after consultation with the sponsor, 
sponsor’s representative, or medical monitor. 
4.6. 
Treatment Compliance 
The prescribed dosage, timing, and mode of administration of Cannabidiol Oral Solution may 
not be changed unless a safety concern or toxicity is identified for a patient.  
Patient compliance will be calculated during Placebo Lead-In Period. Patients taking too much or 
too little study medication should be re-educated on the proper use of study medication. Non-
compliance (<80% or >100%) should be evaluated by the Investigator for the need to withdraw 
the patient. The Investigator should discuss the case with the Medical Monitor.  
4.7. 
Permitted and Prohibited Therapies 
4.7.1. 
Permitted Therapies 
Any medications (other than those excluded by the protocol, see Section 4.7.2) that the 
Investigator considers necessary for a patient’s welfare and will not interfere with the 
investigational product may be given at the Investigator’s discretion. 
4.7.2. 
Prohibited Therapies 
During the Screening, Placebo Lead-In, Titration, Treatment, and Follow-up Periods, patients are 
not to receive the following: 
• Any cannabinoids other than study medication (CBD, Δ9-THC, hemp oil, Realm Oil or 
marijuana). 
• Felbamate. 
• Use of weight loss agents or drugs known to affect appetite (including glucagon-like 
peptide-1[GLP-1] analogs).   
• Any other investigational drug or investigational device.  
• Medication that are strong inhibitors/inducers/ sensitive substrates with a narrow 
therapeutic index for P450 3A4 (CYP3A4), CYP2D6, CYP3A4-, or CYP2D6. 
Although they are not prohibited, patients taking concomitant medications may require that the 
patient is monitored with special care to identify any AEs arising due to the potential for altered 
drug metabolism. 
4.8. 
Treatment After End of Study 
After completion of the study, patients will be offered the chance to enroll into an open-label, 
long-term safety study. Patients who choose to enroll in the long-term safety study will not have 
a follow-up visit. Patients who do not choose to enroll in the long-term safety study will be 
tapered off study medication and complete a follow-up visit approximately 2 weeks after study 
completion.

6.2.5.6. 
Columbia Suicide Severity Rating Scale (C-SSRS) 
The 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. For patients aged 7 to 17 years and if the 
developmental level is appropriate, the questionnaire will be completed at Baseline (Visit 3) and 
Visit 10 (Week 13) or the Early Withdrawal Visit.  
6.2.6. 
Adverse Events and Serious Adverse Events 
6.2.6.1. 
Definition of Adverse Events 
An AE is defined as any untoward medical occurrence in a patient administered a pharmaceutical 
product during the course of a clinical investigation. An AE can therefore be any unfavorable 

Insys Development Company, Inc.                                               Protocol Number INS011-16-085

51 
and unintended sign, symptom, or disease temporally associated with the use of an 
investigational product, whether or not thought to be related to the investigational product. 
Patients will be monitored throughout the study for AEs. Monitoring for treatment-emergent AEs 
(TEAEs) will begin as soon as the patient is dosed. All AEs must be followed until they are 
resolved or stabilized, or until all attempts to determine resolution of the event are exhausted. 
The investigator should use their discretion in ordering additional tests as necessary to monitor 
the progress of such events. 
An AE may be: 
• A new illness, not documented in the patient’s medical history; 
• Worsening of a concomitant illness; 
• An effect of the study medication; it could be an abnormal laboratory value, as well as a 
significant shift from baseline within normal range which the qualified investigator or 
medical qualified designate considers to be clinically important; 
• A combination of two or more of these factors. 
Surgical procedures themselves are not AEs. They are therapeutic measures for conditions that 
require surgery. The condition for which the surgery is required is an AE, if it occurs or is 
detected during the study period. Planned surgical measures permitted by the clinical study 
protocol and the conditions(s) leading to these measures are not AEs, if the condition(s) was 
(were) known before the start of study treatment. In the latter case, the condition should be 
reported as medical history. 
Weight gain or loss will not be recorded as an AE. Hyperphagia behaviors and skin picking will 
not be recorded as AEs; however, any other behaviors may be recorded as AEs based on the 
Investigator’s opinion. 
Patients will be monitored throughout the study for AEs. All AEs must be followed until they are 
resolved or stabilized, or until all attempts to determine resolution of the event are exhausted. 
The investigator should use his/her discretion in ordering additional tests as necessary to monitor 
the progress of such events. 
Adverse events reported prior to dose administration will be recorded as part of the patient’s 
medical history. 
6.2.6.2. 
Classification of Adverse Events 
Adverse events are to be recorded on the AE page of the patient’s case report form (CRF).  
Severity will be graded according to the following definitions: 
• Mild: The patient experiences awareness of symptoms but these are easily tolerated or 
managed without specific treatment. 
• Moderate: The patient experiences discomfort enough to cause interference with usual 
activity, and/or the condition requires specific treatment. 
• Severe: The patient is incapacitated with inability to work or do usual activity, and/or the 
event requires significant treatment measures.

Action taken will be categorized as none, study drug discontinued, dose modified, required 
concomitant medication, required procedure, or other. 
Event outcome at resolution or time of last follow-up will recorded as event resolved, resolved 
with sequelae, ongoing, or death. 
6.2.6.3. 
Causality: Drug Relationship Assessment 
The relationship of the event to the study drug should be determined by the investigator 
according to the following criteria: 
• Definitely related: The event follows a reasonable temporal sequence from the time of 
drug administration that cannot be explained, follows a known or expected response 
pattern to the study drug, that is confirmed by improvement on stopping and 
reappearance of the event on repeated exposure and that could not be reasonably 
explained by other factors such as the patient’s clinical condition, intercurrent illness, or 
concomitant drugs. 
• Not related: The event is most likely produced by other factors such as the patient’s 
clinical condition, intercurrent illness, or concomitant drugs, and does not follow a 
known response pattern to the study drug, or the temporal relationship of the event to 
study drug administration makes a causal relationship unlikely. 
• Possibly related: The event follows a reasonable temporal sequence from the time of drug 
administration, and/or follows a known response pattern to the study drug, but could have 
been produced by other factors such as the patient’s clinical condition, intercurrent 
illness, or concomitant drugs. 
• Unlikely related: The event follows little or no temporal sequence from the time of drug 
administration that makes a causal relationship improbable and/or other factors such as 
the patient’s clinical condition, intercurrent illness, or concomitant drugs is a more likely 
alternative. 
• Probably related: The event follows a reasonable temporal sequence from the time of 
drug administration, and/or follows a known response pattern to the study drug, and 
cannot be reasonably explained by other factors such as the patient’s clinical condition, 
intercurrent illness, or concomitant drugs. 
6.2.6.4. 
Definition of Serious Adverse Events 
A serious AE (SAE) is any AE that fulfills any of the following criteria, as per 21 CFR 312.32: 
• Results in death; 
• Is life-threatening; 
• Requires in-patient hospitalization or prolongation of existing hospitalization; 
• Results in persistent or significant disability or incapacity; 
• Is a congenital anomaly or birth defect; 
• Is medically significant or requires intervention to prevent one of the outcomes listed 
above.

CONFIDENTIAL 
53 
Serious AEs will be captured from the time of consent through the end of the study. 
6.2.6.5. 
Serious Adverse Event Actions Taken  
Actions taken may consist of: 
• None: No action taken 
• Treatment: Standard of care measures instituted 
• Drug withdrawn: Study medication was permanently discontinued because of the AE 
• Unknown: Not known, not observed, not recorded, or refused 
6.2.6.6. 
Serious Adverse Event Outcome at the Time of Last Observation  
The outcome at the time of last observation will be classified as: 
• Recovered/resolved 
• Recovered/resolved with sequelae 
• Not recovered/not resolved 
• Death 
• Unknown 
6.2.6.7. 
Adverse Event Recording and Reporting 
Adverse events will be recorded throughout the study in the source documents and in the CRFs. 
The investigator will rate AEs for seriousness, intensity, causality, action taken, and outcome as 
described in the previous section. 
Expedited reporting is required for serious unexpected adverse drug reactions. Fatal or 
life-threatening unexpected drug reactions must be reported by the Sponsor to regulatory 
agencies no more than 7 days after the Sponsor’s first knowledge of the reaction; followed by as 
complete a report as possible within 8 additional days. Unexpected adverse drug reactions must 
be reported no later than 15 days after the Sponsor’s first knowledge of the reaction. In order to 
comply with these requirements, the investigator or delegate must inform the Sponsor 
immediately upon occurrence of any SAE. The site will complete the SAE Report Form as 
thoroughly as possible and e-mail it to Insys or designee within 24 hours of the investigators first 
knowledge of the event. Details will be provided in the safety monitoring plan. 
These SAE reports must contain the following information: 
A. Study name/number 
B. Study drug

All non-serious AEs that are not related or unlikely to be related to study treatment will be 
followed until the end of study participation. All SAEs or AEs that are considered as possibly, 
probably, or definitely related to treatment will be followed until resolution or stabilization. 
6.2.6.9. 
Special Considerations 
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 patients who are taking concomitant 
medications that are metabolized by CYP2C19, CYP2C9, CYP2D6, CYP3A4, CYP1A2 or by P-
glycoprotein with special care.     
6.2.7. 
Pharmacokinetics Assessments 
Blood draws for PK sampling will be taken at each visit during the Baseline (Visit 3), 
Maintenance Period (Visits 6 and 8), and Study Completion/Early Withdrawal (Visit 10).  
Whole blood will be obtained in a K2-EDTA Vacutainer® tube for the determination of the 
plasma levels of CBD and 7-OH-CBD. The blood sample will be obtained prior to study 
medication dosing.

A total of 30 patients per treatment group will provide more than 85% power with an alpha of 
0.05, for a difference in the HQ-CT from Baseline to Week 13 of 5 points with standard 
deviation of 6. Assuming a 20% drop out rate, approximately 66 patients (33 patients per arm) 
will be randomized to achieve 60 (30 patients/arm) completers. 
8.5. 
Analysis Populations 
Statistical analysis will be done on the following populations: 
• Intent to Treat (ITT) Population: The ITT Population will include all patients who were 
randomized. The ITT Population will be used for all efficacy analyses. 
• Safety Population: The Safety Population will include all patients who were treated with 
at least one dose of the study drug. The Safety Population will be used for all safety 
assessments. 
8.6. 
Statistical Analyses 
8.6.1. 
Study Patients and Demographics 
Analysis Treatment group will be defined by the modal dose of study drug (dose group the 
patient took for the longest period). 
8.6.1.1. 
Disposition and Withdrawals 
The numbers of patients randomized, completing, withdrawing, and reasons for withdrawal, will 
be tabulated overall and by treatment group. The number of patients in each analysis population 
will be reported.  
8.6.1.2. 
Protocol Deviations 
Protocol deviations will be identified and listed. 
8.6.1.3. 
Demographics and Other Baseline Characteristics 
Descriptive analyses will be conducted for the safety population.

Statistical inference for the primary endpoint and for key secondary endpoints will be controlled 
at an overall family wise error rate (alpha) of 0.05, 2-sided. For continuous endpoints, number of 
observations, mean, standard deviation (SD), median, minimum and maximum will be presented 
as descriptive statistics. For inferential statistics, analysis of covariance (ANCOVA) with the 
baseline value and randomization strata (growth hormone treatment) as covariates t will be used. 
For multiple values, a repeated measures analysis will be performed. For categorical endpoints, 
the number of observations, frequency counts and percentages will be presented as descriptive 
statistics, and Fisher’s exact test will be used for inferential statistics.  
8.6.3.1. 
Primary Efficacy Analysis 
The primary outcome variable for the study is the change in total score of the HQ-CT from 
Baseline through Study Completion/Early Withdrawal.  The primary efficacy endpoint will be 
tested using a 2-sided type I error rate of 0.05. 
8.6.3.2. 
Secondary Efficacy Analysis 
The secondary endpoints, which will be assessed inferentially, are change in total body-weight, 
response rate, PGI-C, TFEQ-R18, PROMIS Life Satisfaction and Positive Affect, PROMIS 
Physical Activity and Fatigue.   
8.6.3.3. 
Exploratory Efficacy Analysis

QUALITY CONTROL AND QUALITY ASSURANCE 
The sponsor or its designee will implement and maintain quality control and quality assurance 
procedures with written standard operating procedures to ensure the study is conducted and data 
are generated, documented, and reported in compliance with the protocol, GCP, and applicable 
regulatory requirements. This trial will be conducted in accordance with the provisions of the 
Declaration of Helsinki (October 1996) and all revisions thereof, and in accordance with the 
FDA CFR 312.50 and 312.56, and with the ICH guidelines on GCP (CPMP/ICH/135/95). 
10.1. 
Changes to The Protocol 
The investigator may not deviate from the protocol without a formal protocol amendment 
established and approved by the appropriate IEC/IRB, except when necessary to eliminate 
immediate hazards to the patient or when the change involves only logistical or administrative 
aspects of the study. Any deviation may result in patient withdrawal from the study and 
rendering that patient not available for data evaluation. 
10.2. 
Monitoring 
The investigator will permit the site monitor to review trial data as frequently as is deemed 
necessary to ensure data are being recorded in an adequate manner and protocol adherence is 
satisfactory. The investigator will access medical records for the monitor to verify CRF entries. 
The investigator, as part of his or her responsibilities, is expected to cooperate with the sponsor 
or its designee in ensuring the trial adheres to GCP requirements. The investigator may not 
recruit patients into the study until such time that a site visit has been conducted. 
10.3. 
Data Review Meeting 
The sponsor will review all data reported in CRFs of all patients before database lock. The data 
review meeting determines whether or not all enrolled patients can be included in the analysis 
population according to the specified definition of analysis populations and evaluates whether or 
not medical decisions of the Investigator were appropriate for important data affecting the safety 
and efficacy endpoint. 
10.4. 
Protocol Violations  
The Investigator will conduct the study in compliance with the protocol approved by the IRB. 
Modifications to the protocol should not be performed without agreement of both the 
Investigator and the sponsor. Changes to the protocol will require written IRB approval prior to 
implementation, except when the modification is needed to eliminate an immediate hazard(s) to 
patients. 
The Investigator or sub-investigator should document any deviation from the protocol and the 
reason. If the Investigator performs a deviation from the protocol or a change of the protocol to 
eliminate an immediate hazard(s) to patients, the record should be immediately submitted to the 
sponsor, the Clinical Research Unit (CRU), and the IRB by the Investigator and the IRB will 
provide expedited review and approval. After the Investigator has obtained approval of the IRB, 
the Investigator should obtain written permission of the CRU and written agreement of the 
sponsor.

When deviation from the protocol is required to eliminate immediate hazard(s) to patients, the 
Investigator will contact the sponsor, if circumstances permit, to discuss the planned course of 
action. Any deviations from the protocol must be fully documented in the CRF and source 
documentation.  
10.5. 
Quality Assurance Audit 
This study will be patient to audit by the sponsor, CRO, or designee. 
The sponsor or sponsor’s representative may conduct audits on a selection of study sites, 
requiring access to patient notes, study documentation, and facilities or laboratories used for the 
study. 
The study site, facilities, all data (including source data), and documentation will be made 
available for audit by quality assurance auditors and for IRB or regulatory authorities according 
to GCP guidelines. The investigator agrees to cooperate with the auditor during the visit and will 
be available to supply the auditor with CRFs or other files necessary to conduct that audit. Any 
findings will be strictly confidential. 
If a regulatory authority informs the investigator that it intends to conduct an inspection, the 
investigator shall notify sponsor or sponsor’s representative immediately.

the administration of study medication.     
The investigator or his/her designee will inform the patient of all aspects pertaining to their 
participation in the study. The process for obtaining patient informed consent will be in 
accordance with all applicable regulatory requirements (e.g., CFR Part 50 and ICH E6 Section 
4.8). The investigator or his/her designee and the patient must both sign and date the informed 
consent document (ICD) before the patient can participate in the study. The patient will receive a 
copy of the signed and dated form, and the original will be retained in the site’s study records. 
The decision to participate in the study that is made by the patient is entirely voluntary. The 
investigator or his/her designee must emphasize to the patient that consent for study participation 
may be withdrawn at any time without penalty or loss of benefits to which the patient is 
otherwise entitled. If the ICD is amended during the study the investigator must follow all 
applicable regulatory requirements pertaining to approval of the amended ICD by the IEC/IRB, 
and use of the amended form, including the necessity of re-consenting ongoing patients.
