STUDY SYNOPSIS
Protocol number:  SHP465-309
Drug: SHP465, mixed salts of a single-entity amphetamine 
Title of the study: A Phase 3, Randomized, Double-blind, Multicenter,  Placebo-controlled, Fixed-Dose, 
Efficacy, and Safety Study of SHP465 in Children Aged 6-12 Years with Attention-Deficit/Hyperactivity 
Disorder (ADHD) 
Number of subjects (total and for each treatment arm):
Approximately 60 subjects will be enrolled into the study. Approximately 52 subjects are expected to complete 
the safety and efficacy evaluation: approximately 50% of subjects will be aged 6-8 years and approximately 
50% of subjects will be aged 9-12 years.  Approximately 25% of all subjects will be female.
Investigator(s): Multicenter 
Site(s) and Region(s): 
Approximately 45 sites in the United States (US).
Study period (planned):
2017 to 2018
Clinical phase:
3
Objectives:
Primary: To evaluate the efficacy of SHP465 at 6.25 mg compared to placebo as a daily morning dose in 
children 6-12 years of age (inclusive at the time of consent) diagnosed with ADHD. The primary measure of 
efficacy will be the clinician-administered ADHD-Rating Scale 5 Child, Home version (ADHD-RS-5) Total 
score.
Key Secondary: To assess the efficacy of SHP465 at 6.25 mg compared to placebo using a global clinical 
measure of improvement, the Clinical Global Impression of Improvement (CGI-I) scale.
Secondary:  
To evaluate safety and tolerability of SHP465 at 6.25 mg based on the occurrence of treatment-emergent 
adverse events (TEAEs), evaluation of vital signs (systolic and diastolic blood pressure and pulse), weight, 
height, body mass index (BMI); clinical laboratory and electrocardiogram (ECG) results; sleep assessment (Post 
Sleep Questionnaire [PSQ] and Children’s Sleep Habits Questionnaire [CSHQ]); and responses to the 
Columbia-Suicide Severity Rating Scale (C-SSRS).
Rationale:
The purpose of this study is to evaluate the efficacy and safety of SHP465 at 6.25 mg in the treatment of ADHD 
in children aged 6-12 years. Results from the completed SHP465-305 study in this age group have demonstrated 
SHP465 to be well tolerated and efficacious in reducing ADHD symptom severity. This study will provide 
additional data to inform clinicians about the efficacy and safety of SHP465 at lower dose levels in the pediatric 
ADHD population.
Investigational product, dose, and mode of administration:

SHP465 will be provided in 6.25 mg capsules.

Placebo will be provided as capsules identical to SHP465.
The parent/legally authorized representative (LAR) will be instructed to dispense 1 capsule to the subject daily 
throughout the study at 7:00 AM (±2 hours). SHP465 6.25 mg will be administered in 1 of the following ways:

Swallow SHP465 capsules whole, or

Open capsule and sprinkle the entire contents on applesauce

Shire
CONFIDENTIAL
Page 14
Study Protocol 
SHP465-309 
07 September 2017
The sprinkled applesauce should be consumed immediately; it should not be stored. Subjects should take the 
applesauce with sprinkled beads in its entirety without chewing.
Methodology:
This study is a Phase 3 randomized, multicenter, double-blind, placebo-controlled, fixed-dose efficacy and 
safety study in children aged 6-12 years (inclusive at the time of consent,) diagnosed with ADHD. Children with 
ADHD will be randomized in a 1:1 ratio between SHP465 6.25 mg and placebo arms for a 4-week treatment.  
SHP465 dose of 6.25 mg or placebo will be administered to subjects for the entire treatment period.
The study will have 3 periods: (1) screening and washout: (2) treatment period; and (3) safety follow-up.   The 
duration of the evaluation period will be 4 weeks. 
Subjects will be required to visit the site up to 6 times over a 10-week period. 
The investigator or designee must obtain written informed consent from the subject's parent/LAR and 
documentation of assent (if applicable) by the subject before any protocol-related procedure is performed. 
Procedures performed at each visit for all subjects are defined in the Study Schedule, Table 1. 
Inclusion and exclusion criteria:
Inclusion Criteria:
The subject will not be considered eligible for the study without meeting all of the criteria below (including test 
results):
Subject is male or female and must be 6-12 years, inclusive, at the time of consent.
1.
Subject’s parent or legally authorized representative (LAR) must provide signature of informed 
consent, and there must be documentation of assent (as applicable) by the subject in accordance with 
the International Council on Harmonisation (ICH) Good Clinical Practice (GCP) Guideline E6 (1996) 
and any updates and applicable regulations, before completing any study-related procedures.
2.
Subject and parent/LAR are willing and able to comply with all of the testing and requirements defined 
in the protocol, including oversight of morning dosing. Specifically, the parent/LAR must be available 
at approximately 7:00 AM (±2 hours) to dispense the dose of investigational product for the duration of 
the study.
3.
Subject must meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) 
criteria for a primary diagnosis of ADHD (any subtype) based on a detailed psychiatric evaluation 
using the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID).
4.
Subject who is a female and of child-bearing potential must not have a positive serum beta human 
chorionic gonadotropin pregnancy test at the screening visit (Visit 1) and must have a negative urine 
pregnancy test at the baseline visit (Visit 2) and agree to comply with any applicable contraceptive 
requirements of the protocol.
5.
Subject has an ADHD-RS-5 Child, Home Version Total Score of ≥28 at baseline (Visit 2).
6.
Subject has a Clinical Global Impression – Severity of Illness (CGI-S) score ≥4 at baseline (Visit 2).
7.
Subject functions as an age-appropriate level intellectually, as determined by the investigator.

Endpoints and statistical analysis:
Analysis Sets

Screened Set: all subjects who have provided an informed consent.

Randomized Set:  all subjects in the screened set for whom a randomization number has been assigned.

Safety Set: all subjects in the randomized set who have taken at least 1 dose of investigational product.

Full Analysis Set (FAS):  all subjects in the safety set who have at least 1 post-dose ADHD-RS-5 Total 
Score.
Efficacy Analyses
The FAS will be used to report the efficacy data.
The primary efficacy endpoint is defined as the change from baseline for the ADHD-RS-5 Total Score at Visit 6 
(Week 4), where baseline is defined as the last ADHD-RS-5 Total Score assessment prior to the first dose of 
double blind investigational product, usually at Visit 2. The primary and key secondary analyses will be 
conducted based on the entire age group in the FAS. 
The primary efficacy analysis will be conducted for the change from baseline in the ADHD-RS-5 Total Scores, 
including all assessments from Visit 3 (Week 1) up to Visit 6 (Week 4), using the linear mixed-effects model 
for repeated measures (MMRM) with treatment group, visit, age group and the interaction of treatment group 
with visit as factors, baseline ADHD-RS-5 Total Score as a covariate, and the interaction of the baseline 
ADHD-RS-5 Total Score with visit adjusted in the model. The primary contrast of interest will be at Visit 6 
(Week 4) for SHP465 6.25 mg compared with placebo at the 2-tailed significance level of 0.05. 
The null and alternative hypotheses of the primary efficacy analysis will be the following:

Null hypothesis: There is no difference in primary endpoint mean change from baseline at Visit 6 
(week 4) in ADHD-RS-5 total scores between SHP465 6.25 mg and placebo.

Alternative hypothesis: There is a difference in primary endpoint mean change from baseline at Visit 6 
(week 4) in ADHD-RS-5 total scores between SHP465 6.25 mg and placebo.
As the primary efficacy analysis (MMRM) relies on the assumption that the missing data mechanism follows 
the MAR (missing-at-random) scenario, appropriate sensitivity analyses to examine the effect of data that are 
missing not at random and robustness on the results of the primary analysis will be conducted. 

Shire

Study Protocol 
SHP465-309 
07 September 2017
One sensitivity analysis model assumes that a subject on SHP465 6.25 mg treatment with missing data follows 
the distribution of the placebo responses, i.e., the means and the intra-subject correlations based on the placebo 
responses will apply. Another sensitivity analysis model will be performed under the assumption that subjects 
who drop out perform worse than MAR by a penalty. The details of the sensitivity analysis methods will be 
specified in the Statistical Analysis Plan (SAP).
The key secondary efficacy endpoint, CGI-I will be analyzed using the same analysis method (MMRM) as for 
the primary efficacy endpoint. The baseline CGI-S score will be used as the covariate. The primary contrast of 
interest will be at Visit 6 (Week 4) for SHP465 6.25 mg compared with placebo at the 2-tailed significant level 
of 0.05. Appropriate sensitivity analyses to explore the effect of data that are missing not at random on the 
results of the key secondary efficacy analysis will be specified in the SAP.
In order to protect the study-wide Type I error at the 2-sided 0.05 level for testing across the primary and the 
key secondary hypotheses, the Fixed-Sequence Test procedure will be applied. The hypotheses will be tested in 
order of the primary (ADHD-RS-5 Total Score) and then the key secondary (CGI-I), if significant for the 
primary, each at the 2-sided 0.05 significance level. Both tests in the sequence are based on the MMRM. 
The key secondary efficacy measurement will also be analyzed using the proportion of subjects with an 
“improved” CGI-I measurement at Visit 6/ET (Week 4/ET). In this approach, the CGI-I categories will be 
dichotomized into 2 categories, “very much improved” and “much improved” classified as “improved” and all 
other assessed categories grouped together as “not improved”. If missing data exist at the Visit 6 (Week 4) visit, 
the visit will be imputed by carrying forward the last post baseline observation value. The secondary efficacy 
analysis for the dichotomized CGI-I will be conducted to compare SHP465 6.25 mg and placebo on the FAS for 
the “improved” rate using a Cochran-Mantel-Haenszel test stratified by age group and CGI-S value at baseline.
Treatment effect of SHP465 6.25 mg on primary and key secondary efficacy measures will be estimated using a 
similar model as the primary efficacy endpoint for each age group (6-8 years vs. 9-12 years),  sex, race (white 
and nonwhite), and ethnicity subgroup.
Safety Analyses
Safety data will be analyzed for the safety set. Safety endpoints include the occurrence of TEAEs, systolic and 
diastolic blood pressure, pulse, and weight, height, BMI, ECG results, clinical laboratory test results, PSQ, 
CSHQ, and C-SSRS Exposure to investigational product will be summarized.
Adverse events will be coded using the agreed upon version of the Medical Dictionary for Regulatory Activities 
(MedDRA). Treatment emergent AEs will be summarized. The number and percent of subjects with TEAEs 
will be calculated for each system organ class, by preferred term, and by treatment. The severity of the TEAEs, 
the relationship to the investigational product, TEAEs causing study discontinuation, and serious AEs will also 
be presented. 
Vital signs (systolic and diastolic blood pressure, and pulse), weight, height, BMI, and ECG results including 
potentially clinically important results will be summarized by treatment and visit.
Clinical laboratory test results will be descriptively presented by treatment group for each visit. Shifts of clinical 
laboratory abnormality from baseline to Visit 6/ET will be presented. Number and percent of subjects with 
potentially clinically important laboratory values will be presented by treatment group.
The PSQ and CSHQ results will be summarized by treatment and visit. 
The C-SSRS results will be summarized and listings of the C-SSRS data will be provided for subjects with a 
positive response.
The safety data on TEAEs will also be descriptively summarized by treatment within each age group (6-8 years 
vs. 9-12 years), sex, race, and ethnicity subgroups.
Sample Size Calculation and Power Considerations
Approximately 60 subjects will be randomized in a 1:1 ratio to SHP465 6.25 mg and placebo to achieve 
52 completers for the study (26 in each treatment group) and 85% power for the primary efficacy analysis at the 
2-sided 0.05 significance level.

The sample size planned is estimated based on the primary comparison between SHP465 6.25 mg and placebo 
on the primary efficacy endpoint change from baseline in ADHD-RS-5 total score at Visit 6 (Week 4). 
Assumptions for the calculation include the true mean difference of 11.9 with the common standard deviation 
(SD) of 14 for an effect size of 0.85, and a dropout rate of 15%.
The effect size of 0.85 is low compared with that observed in recently completed study (SHP465-305) of 
children and adolescents aged 6-17 years with ADHD treated with SHP465. The SHP465-305 study yielded an 
effect size of 0.93 in children aged 6-12 years (N=101 subjects).
Planned Interim Analysis
A blinded interim analysis at the late stage of the trial (when approximately 75% of all randomized subjects 
have either completed or discontinued from the study) will be performed to reassess the sample size in case of 
an underestimated variability postulated at the design stage.
Using the cumulative real data, a blinded, pooled analysis of both treatment groups for estimating variability 
will be conducted on the change from baseline in ADHD-RS-5 total score at Visit 6 (Week 4). If the 
re-estimated pooled standard deviation is larger than the 14 postulated at the design stage, the final total number 
of subjects to be enrolled will be calculated using the re-estimated pooled standard deviation together with the 
assumed treatment difference of 11.9 (Friede et al, 2006). If the re-estimated pooled standard deviation is 
smaller than 14, the sample size will not be adjusted.

BACKGROUND INFORMATION
SHP465 extended-release capsules contain mixed salts of a single-entity amphetamine, a 
CNS stimulant. The product was previously referred to as SPD465 however it is now 
being studied under the code of SHP465. SHP465 contains equal amounts (by weight) of 
4 salts: dextroamphetamine sulfate and amphetamine sulfate, dextroamphetamine saccharate 
and amphetamine aspartate monohydrate. This results in a 3:1 mixture of dextro- to 
levo- amphetamine base equivalent.
SHP465 capsules are for oral administration. They contain 3 types of drug-releasing 
beads, an immediate release and 2 different types of delayed release (DR) beads. The first 
DR bead releases amphetamine at pH 5.5 and the other DR bead releases amphetamine at 
pH 7.0. 
Amphetamines are noncatecholamine sympathomimetic amines with central nervous system 
stimulant activity. Amphetamine increases the availability of biogenic amines (primarily 
dopamine and norepinephrine) in central nerve terminals through multiple actions, including 
stimulating neurotransmitter release into the nerve terminal and inhibiting reuptake from the 
synapse. These actions may be the basis of its therapeutic actions in ADHD; however, the mode 
of therapeutic action in ADHD is not known.
Additional information can be found in the current Investigator's Brochure (IB) for SHP465.
1.1
Indication and Current Treatment Options 
Attention-deficit/hyperactivity disorder is a psychiatric disorder characterized by 
developmentally inappropriate degrees of inattentiveness, impulsivity, and hyperactivity. 
Although ADHD is the most common neurodevelopmental disorder of childhood (Rowland et al. 
2002) and it has been extensively studied in young children, ADHD occurs in all age groups 
(Brown 2000).
Prevalence estimates of ADHD in school-age children have ranged from 2-18% in community 
samples (Rowland et al. 2002; Centers for Disease Control and Prevention 2005). The 
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition – Text Revision®
estimates that the disorder is prevalent in 3-7% of school-age children (American Psychiatric 
Association 2000). An analysis of data from the National Survey of Children’s Health performed 
by the Centers for Disease Control and Prevention (2005) estimates that 7.8% of children aged 
4-17 years have been diagnosed with the disorder in the US as of 2003.
Although ADHD was initially believed to be predominantly a childhood disorder, the advent 
of consensus diagnostic criteria for ADHD along with more rigorous prospective research 
has documented the persistence of this disorder into adolescence in up to 70% and into 
adulthood in up to 66% of childhood cases (Mannuzza et al. 1998; Barkley 1998; Zametkin and 
Ernst 1999). Despite the prevalence of ADHD in all age groups, the majority of studies 
have been done in children and adults.

A review of available literature indicates that psychostimulants are efficacious in treating 
adolescents as well as the treatment for younger children with ADHD (Biederman et al. 1996; 
Findling et al. 2001).
The 3 main symptoms of ADHD are inattention, hyperactivity, and impulsivity. Symptoms of 
inattention include difficulty paying attention, making careless mistakes, difficulty organizing 
tasks, not finishing tasks, not listening, and being forgetful and easily distracted. Symptoms of 
hyperactivity and impulsivity include fidgeting, running, or moving about when expected to be 
still, difficulty playing quietly, talking excessively, and interrupting others. Many people have 
symptoms like these occasionally, but patients with ADHD have these symptoms more often and 
to a greater extent than others their age. These symptoms must appear before age 7 years, be 
present for more than 6 months, and must be adversely affecting social, occupational, or school 
functioning for the diagnosis of ADHD to be made.
The presumed pathophysiology of ADHD is an abnormality in central dopaminergic and 
noradrenergic tone (Biederman and Spencer 1999). This presumption is based on the 
discovery that effective pharmacotherapies in children and adults have an impact on these 
2 neurotransmitters (Wilens and Spencer 2000; Faraone and Biederman 1998).
Stimulants, including amphetamine and methylphenidate products are currently the most 
prescribed medications for the treatment of ADHD. Other nonstimulant classes of medications 
are also approved for the treatment of ADHD including a norepinephrine reuptake inhibitor, 
STRATTERA® (atomoxetine hydrochloride) and alpha-2-agonists, INTUNIV® (guanfacine 
hydrochloride) and KAPVAY® (clonidine hydrochloride). However, comprehensive reviews of 
clinical studies investigating the pharmacotherapy of ADHD clearly demonstrate that stimulant 
medications (ie, methylphenidate and amphetamine) produce the most robust improvements in 
symptom expression across age ranges as compared with nonstimulant therapies (Faraone et al. 
2006).

Product Background and Clinical Information
1.2.1
Clinical Information
SHP465 and its prototypes have been evaluated in 1641 subjects in 16 clinical studies, of which 
13 clinical studies were in adult subjects aged 18 to 55 years and 3 clinical studies were in 
pediatric subjects aged 6 to 17 years. The SHP465 clinical development program has shown that 
doses of 12.5 to 50 mg in adult subjects and 6.25 to 25 mg in pediatric subjects demonstrate a 
safety and efficacy comparable to the profile reflected in class labeling for stimulant products 
approved in the United States (US).
The pharmacokinetic (PK) profile of SHP465 is not affected if the capsule is consumed intact or 
if capsule contents are sprinkled onto a small amount of food (ie, 1 tablespoon of applesauce) 
and then ingested. The PK properties of SHP465 are not affected by sex or race. The PK 
properties between d- and l-amphetamine are similar.

Acceptable safety and tolerability profiles observed were consistent with the types of side effect 
specified in stimulant class labeling in the US. Specifically, administration of SHP465 was 
associated with increases in blood pressure (mean increase approximately 2-4 mmHg) and heart 
rate (mean increase approximately 3-6 bpm), and treatment-emergent adverse events (TEAEs) of 
insomnia, decreased appetite, decreased weight, heart rate increased, and anxiety, as well as 
psychiatric events (eg, mania, suicidality).

Study Objectives
2.2.1
Primary Objectives
To evaluate the efficacy of SHP465 at 6.25 mg compared to placebo as a daily morning dose in 
children 6-12 years of age (inclusive at the time of consent) diagnosed with ADHD. The primary 
measure of efficacy will be the clinician-administered ADHD-Rating Scale 5 Child, Home 
version (ADHD-RS-5) Total score.
2.2.2
Secondary Objectives
Key Secondary: 

To assess the efficacy of SHP465 at 6.25 mg compared to placebo using a global clinical 
measure of improvement, the Clinical Global Impression of Improvement (CGI-I) scale.
Secondary: 

To evaluate safety and tolerability based on the occurrence of treatment-emergent adverse 
events (TEAEs), evaluation of vital signs (systolic and diastolic blood pressure and pulse), 
weight, height, body mass index (BMI); clinical laboratory and electrocardiogram (ECG) 
results; sleep assessments (Post Sleep Questionnaire [PSQ] and Children’s Sleep Habits 
Questionnaire [CSHQ]); and responses to the Columbia-Suicide Severity Rating Scale

4.4.1.1
Systolic and Diastolic Blood Pressure
Blood pressure criteria for further evaluation have been developed based on the normative data
presented in the National Institutes of Health Fourth Report on the Diagnosis, Evaluation, and 
Treatment of High Blood Pressure in Children and Adolescents (NIH, 2004).
Prior to obtaining vital signs (blood pressure and pulse) the subjects should be at rest for at least 
3 minutes.
If any subject’s blood pressure measurements meet either criterion below, the investigator will 
notify the medical monitor. If any subject’s blood pressure measurements meet either criterion 
below on 3 consecutive visits, the subject should be considered for potential discontinuation 
based upon the clinical judgment of the investigator and in conjunction with the medical 
monitor. 

Elevations in the average (of 3 readings) sitting systolic blood pressure defined as an increase 
of >15 mmHg from the baseline visit (Visit 2) OR a value >95th percentile for age, sex, and 
height.

Elevations in average (of 3 readings) sitting diastolic blood pressure defined as an increase of 
>15 mmHg from the baseline visit (Visit 2) OR an average (of 3 readings) sitting diastolic 
blood pressure value >95th percentile for age, sex, and height.
Any subject with a systolic or diastolic blood pressure measurement <95th percentile for age, sex, 
and height percentile may be discontinued from the study based upon the clinical judgment of 
the investigator regarding the subject’s safety.
4.4.1.2
Pulse
The resting pulse rate criterion for further evaluation has been defined based on the normative 
data presented in the National Health Statistics Report’s “Resting Pulse Rate Reference Data for 
Children, Adolescents, and Adults: United States, 1999-2008” (Ostchega et al., 2011).
Any subject that has a resting, sitting pulse rate >116 bpm (based on the average of 3 readings) 
and or is symptomatic requires further assessment. In this case an unscheduled visit needs to be 
conducted within 1 business day. At the unscheduled visit, if the subject’s pulse rate remains 
>116 bpm (based on the average of 3 readings) or if the subject is symptomatic then the subject’s 
investigator will discuss the findings with the medical monitor. In careful consideration of the 
subject's pulse value, magnitude of increase from the baseline, and symptoms, a joint decision 
between the investigator and the medical monitor will be made regarding continued participation 
in the study. If a visit cannot be scheduled the next day, the subject may be discontinued from the 
study.
Any subject with a pulse rate equal or lower than the number for age defined above may be 
discontinued from the study based upon the clinical judgment of the investigator regarding the 
subject’s safety.

INVESTIGATIONAL PRODUCT
6.1
Identity of Investigational Product
The test product is SHP465, which will be provided in 6.25 mg capsule form. Additional 
information is provided in the current SHP465 IB. The product was previously referred to as 
SPD465 and is registered with the Drug Enforcement Agency (DEA) as SPD465; however, it is 
now being studied under the code of SHP465. The drug will be labeled with SHP465 (SPD465).
The reference/comparator product is placebo which will also be provided in capsule form.  
6.1.1
Blinding the Treatment Assignment
The actual treatment given to individual subjects is determined by a randomization schedule. A 
randomization schedule will be prepared to assign eligible subjects to 1 of 2 treatment groups 
with an allocation ratio of 1:1 (SHP465 6.25 mg or placebo). The associated treatment 
assignments giving details of individual subject treatment are automatically defined by the 
IWRS. At each visit, subjects will be supplied bottles of investigational product that have been 
individually allocated by IWRS, and instructed to take 1 capsule every morning. All 
investigational product (SHP465 6.25 mg or placebo) will appear identical, in order to protect the 
study blind. 
6.2
Administration of Investigational Product(s)
6.2.1
Interactive Response Technology for Investigational Product Management
An IWRS will be employed in this study to manage the tracking and confirmation of shipment, 
supply, inventory, ordering, expiration, site-assignments, subject randomization, returns, and 
emergency unblinding of the investigational product. 
The IWRS provider will provide a user manual and training to each site, with detailed instruction 
on use of the IWRS.
6.2.2
Allocation of Subjects to Treatment 
This is a double-blind, placebo-controlled study. The actual treatment given to individual 
subjects is determined by a randomization schedule. Subjects will be randomly assigned in a 
1:1 ratio to SHP465 6.25 mg or placebo. Randomization will be stratified to ensure 
approximately 50% of subjects in each age group (6-8 years and 9-12 years), and to facilitate 
balance of treatment allocation within each age group.
Subject numbers are assigned to all subjects as they consent to take part in the study. Within each 
site (numbered uniquely within a protocol), the subject number is assigned to subjects according 
to the sequence of presentation for study participation. 
The randomization number represents a unique number corresponding to investigational product 
allocated to the subject, once eligibility has been determined. 

Shire
CONFIDENTIAL
Page 37
Study Protocol 
SHP465-309 
07 September 2017
Individual subject treatment is automatically assigned by the interactive response technology.
Investigational product packaging identification numbers, separate from randomization 
numbers/unique identifiers, may also be assigned to subjects for specific treatment assignment as 
dictated by the study. In these cases, the same investigational product packing identification 
number may not be assigned to more than 1 subject.
6.2.3
Dosing
Dosing should begin at approximately 7:00AM (±2 hours) on the morning after the baseline visit 
(Visit 2). Subjects will be instructed to take 1 capsule daily in the morning throughout the study, 
at approximately the same time each day. The same parent/LAR should be available daily to 
dispense the dose of investigational product for the study duration.
The investigational product may be administered in 1 of the following ways:

Swallow the capsule whole, or

Open capsule and sprinkle the entire contents over a spoonful of applesauce. The sprinkled 
applesauce should be consumed immediately; it should not be stored. Subjects should take 
the sprinkled applesauce in its entirety without chewing. The dose of a single capsule should 
not be divided. The empty capsule shells should be discarded.
6.2.4
Unblinding the Treatment Assignment
The treatment assignment must not be broken during the study except in emergency situations 
where the identification of the investigational product is required for further treatment of the 
subject. The investigator should contact the medical monitor as soon as possible after the 
investigator has been unblinded. 
In the event that the treatment assignment is broken, the date, the signature of the person who 
broke the code, and the reason for breaking the code are recorded on the IWRS and the source 
documents. Upon breaking the blind, the subject is withdrawn from the study, but should be 
followed up for safety purposes. Any code-breaks that occur must be reported to the CRO and 
sponsor. Code-break access will be provided to the investigator/designated person at the site and 
by the CRO medical monitor for the study.
For blinded studies, there will be a provision for unblinding to ensure adequate treatment of the 
subject in the case of an emergency.
6.3
Labeling, Packaging, Storage, and Handling
6.3.1
Labeling
Labels containing study information and pack identification are applied to the investigational 
product(s) container. 

Shire
CONFIDENTIAL
Page 38
Study Protocol 
SHP465-309 
07 September 2017
A computer-generated label is applied to the investigational product. All investigational 
product is labeled with a minimum of the protocol number, pack number (if applicable), dosage 
form (including product name and quantity in pack), directions for use, storage conditions, 
expiry date (if applicable), batch number and/or packaging reference, the statement ‘CAUTION: 
New Drug - Limited by Federal (or United States) Law to Investigational Use’, and ‘Keep out of 
reach of children’, and the sponsor's name and address. Any additional labeling requirements for 
participating countries and/or controlled substances will also be included on the label.
Space is allocated on the label so that the site representative can record a unique subject 
identifier and initials.
Additional labels (eg, those used when dispensing marketed product) may, on a case-by-case 
basis, be applied to the investigational product in order to satisfy local or institutional 
requirements, but must not:

Contradict the clinical study label

Obscure the clinical study label

Identify the study subject by name
Additional labels may not be added without the sponsor’s prior full agreement.
6.3.2
Packaging
Investigational product is packaged in the following labeled containers:
9-count high density polyethylene bottles with child-resistant closures.
Changes to sponsor-supplied packaging prior to dosing may not occur without full agreement in 
advance by the sponsor.
6.3.3
Storage
The investigator has overall responsibility for ensuring that investigational product is stored in a 
secure, limited-access location. Limited responsibility may be delegated to the pharmacy or 
member of the study team, but this delegation must be documented. Investigational products are 
distributed by the pharmacy or nominated member of the study team. The pharmacist/nominated 
team member will enter the unique subject identifier initials on the investigational product 
bottle/carton labels as they are distributed.
Investigational product must be stored in accordance with labeled storage conditions. 
Temperature monitoring is required at the storage location to ensure that the investigational 
product is maintained within an established temperature range. The investigator is responsible 
for ensuring that the temperature is monitored throughout the duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house system, a mechanical recording device such as a calibrated chart recorder, or by manual 
means, such that both minimum and maximum thermometric values over a specific time period 
can be recorded and retrieved as required.

Such a device (ie, certified min/max thermometer) would require manual resetting upon each 
recording. The sponsor must be notified immediately upon discovery of any excursion from the 
established range. Temperature excursions will require site investigation as to cause and 
remediation. The sponsor will determine the ultimate impact of excursions on the investigational 
product and will provide supportive documentation as necessary. Under no circumstances should 
the product be dispensed to subjects until the impact has been determined and the product is 
deemed appropriate for use by the sponsor.
The sponsor should be notified immediately if there are any changes to the storage area of the 
investigational product that could affect the integrity of the product(s), eg, fumigation of a 
storage room.
All controlled-substance investigational product for the sponsor’s studies must be stored in a 
securely locked, substantially constructed room or cabinet according to all applicable local, state, 
and/or national laws. Limited, controlled access to these investigational products must be 
maintained, as well as chain of custody, for all investigational product movement.
6.4
Drug Accountability
Investigators will be provided with sufficient amounts of the investigational product to carry out 
this protocol for the agreed number of subjects. The investigator or designee will acknowledge 
receipt of the investigational product, documenting shipment content and condition. Accurate 
records of all investigational product dispensed, used, returned, and/or destroyed must be 
maintained as detailed further in this section.
The investigator has overall responsibility for administering/dispensing investigational product. 
Where permissible, tasks may be delegated to a qualified designee (eg, a pharmacist) who is 
adequately trained in the protocol and who works under the direct supervision of the investigator. 
This delegation must be documented in the applicable study delegation of authority form. The 
investigator or designee will be required to have a valid DEA Form 223 certificate of registration 
for 2N Controlled Substances for the duration of the study, and be able to order and distribute 2N 
Controlled Substances via a valid DEA Form 222.
The investigator or his/her designee (as documented by the investigator in the applicable study 
delegation of authority form) will dispense the investigational product only to the parent/LAR of 
subjects included in this study following the procedures set out in the study protocol. Each 
subject will be given only the investigational product carrying his/her treatment assignment. All 
dispensed will be documented on the CRFs and/or other investigational product record. The 
investigator is responsible for assuring the retrieval of all study supplies from each subject's 
parent/LAR. 
No investigational product stock or returned inventory from a Shire-sponsored study may be 
removed from the site where originally shipped without prior knowledge and consent by the 
sponsor. If such transfer is authorized by the sponsor, all applicable local, state, and national 
laws must be adhered to for the transfer.

Shire
CONFIDENTIAL

Study Protocol 
SHP465-309 
07 September 2017
The sponsor or its representatives must be permitted access to review the supplies storage and 
distribution procedures and records provided that the blind of the study is not compromised.
At the end of the study, or as instructed by the sponsor, all unused stock, subject-returned 
investigational product, and empty/used investigational product packaging are to be sent to a 
nominated contractor on behalf of the sponsor. Investigational products being returned to the 
sponsor’s designated contractors must be counted and verified by clinical site personnel and the 
sponsor (or designated CRO). For unused supplies where the original supplied tamper-evident 
feature is verified as intact, the tamper-evident feature must not be broken and the labeled 
amount is to be documented in lieu of counting. Shipment return forms, when used, must be 
signed prior to shipment from the site. Validated electronic return systems (ie, interactive 
response technology) do not require a shipment form. Returned investigational products must be 
packed in a tamper-evident manner to ensure product integrity. Contact the sponsor for 
authorization to return any investigational product prior to shipment. Shipment of all returned 
investigational product must comply with local, state, and national laws.
Based on entries in the site drug accountability forms, it must be possible to reconcile 
investigational products delivered with those used and returned. All investigational products 
must be accounted for and all discrepancies investigated and documented to the sponsor’s 
satisfaction.
6.5
Subject Compliance
The parent/LAR of each subject must be instructed to bring their unused investigational product 
and empty/used investigational product packaging to every visit. Drug accountability must be 
assessed at the container/packaging level for unused investigational product that is contained 
within the original tamper-evident sealed container (eg, bottles, trays, vials) or at the individual 
count level for opened containers/packaging. The pharmacist/nominated person will record 
details on the drug accountability form.

STUDY PROCEDURES
7.1
Study Schedule
The Schedule of Assessments (Table 1) details all procedures to be completed at each visit and 
should serve as the primary section of the protocol regarding visit-specific study procedures.
Clinician completed rating scales and assessments conducted by the site, ie, ADHD-RS-5, 
CGI-S, CGI-I, and C-SSRS should be completed by the same rater with input from the same 
parent/LAR whenever possible. The parent/LAR completed CSHQ should be completed 
whenever possible. 
Throughout the treatment period of the study, visits should be scheduled as outlined (±2 days) 
with reference to the baseline visit (Visit 2). The safety follow-up call should be scheduled 
7 days post last dose with a +2 day visit window.
Additional unscheduled visits and/or assessments may occur as needed for safety (eg, 
unscheduled visits for blood pressure and/or pulse measurements). 
7.1.1
Screening and Washout Period 
The principal investigator or his/her designee must obtain written informed consent from the 
subject’s parent/LAR prior to any study-related procedures conducted during the screening visit 
(Visit 1). There must also be documentation of assent (if required by the Institutional Review 
Board [IRB]), indicating that the subject is aware of the investigational nature of the study and 
the required procedures and restrictions, prior to the performance of any study-related 
procedures.
A washout period may be required to discontinue any prohibited medication (Table 2). A subject 
cannot be instructed to washout any medication for this study until after informed consent is 
obtained.
Screening procedures may take place across multiple days to allow enough time to complete 
all procedures and confirm initial subject eligibility. Screening procedures and dates should be 
well documented in the source documents. The date of the screening visit (Visit 1) is the date 
the parent/LAR has signed informed consent for this study. Subjects requiring washout must 
have an abbreviated physical examination, clinical laboratory tests, and 12-lead ECG repeated if 
>32 days have elapsed since the safety measurements at the screening visit (Visit 1) were 
collected.

7.1.1.1
Screening Visit (Visit 1) 
Subjects will be screened at Visit 1 to establish eligibility for study participation. 
Table 1 details all procedures to be completed at the screening visit (Visit 1). Additional 
clarification on the procedures performed during the screening visit (Visit 1) is provided below:

Eligibility will be established per inclusion and exclusion criteria, including documentation 
of any prior nonpharmacological treatment, specified Mini International Neuropsychiatric 
Interview for Children and Adolescents (MINI KID), and C-SSRS criteria. Areas of 
impairment will be recorded for all subjects for assessing the severity of the subject’s 
condition.

All adverse events (AEs) occurring after signature of informed consent must be recorded in 
the source documents and CRF.

Three ECGs will be taken, with approximately 3 minutes in between each one, to ensure 
appropriate baseline intervals are established. The investigator will perform the initial 
interpretation of the ECG immediately after collection to ensure the safety of each subject. 
The ECG tracing will be sent to the central reader for analysis. Upon review of the report 
from the central reader, the investigator will re-evaluate the clinical significance of the ECG 
in light of other safety data for the subject. If abnormal and significant results are observed 
following assessment by the central reader, the investigator, in consultation with the 
appointed CRO Medical Monitor, will confirm the subject’s eligibility to participate in this 
study.

Blood pressure and pulse will be collected 3 times (with approximately 2 minutes in between 
each collection) using the age-appropriate cuff during the visit. 

The “baseline” version of the C-SSRS should be completed.

Record historical/concomitant medications as follows:
-
All lifetime psychoactive medications and lifetime nonpharmacological interventions 
(behavioral therapy) for ADHD
-
Other medications used during the 30 days prior to the screening visit (Visit 1)
A screen failure is a subject who has given informed consent and failed to meet the inclusion 
criteria and/or met at least 1 of the exclusion criteria and has not been randomized or 
administered investigational product. For screen failure subjects, the investigator or assigned site 
staff designee will access the IWRS to record the subject as a screen failure.
Subjects cannot be rescreened once they have been designated as a screen failure.
7.1.1.2
Washout Telephone Call
The washout period should be initiated after clinical laboratory test results and 12-lead ECG 
results have been received and reviewed by the investigator. Eligible subjects will be 
contacted by a member of the site staff and provided with instructions on discontinuing any 
protocol-prohibited medications. 

Shire
CONFIDENTIAL
Page 43
Study Protocol 
SHP465-309 
07 September 2017
During washout, a subject’s current prohibited medications (if applicable) will be discontinued 
for a period of a minimum of 5 times the half-life of the medication. Washout periods for 
prohibited medications are defined in Table 2.
As part of the washout telephone call, site personnel should perform the following procedures.

Schedule the baseline visit (Visit 2).

Review the inclusion/exclusion criteria.

Ask about any concomitant medications that the subject is taking. If new concomitant 
medications that require washout are noted, instructions for appropriate washout should be 
provided. 

Provide instructions on discontinuing any medication requiring washout.

Determine if any AEs have occurred since the screening visit (Visit 1).
If a medication washout is not necessary, the washout telephone call will include all the above 
procedures except providing instructions on discontinuing any current medications and must 
occur prior to the baseline visit.
7.1.1.3
Baseline Visit (Visit 2)
Once the screening central clinical laboratory tests and 12-lead ECG results have been obtained, 
in addition to repeat assessments (if required), and the subject has completed the required 
washout period (if applicable), the subject will return to the site for the baseline visit (Visit 2).
Inclusion/exclusion criteria must also be reviewed during this visit to ensure subjects continue to 
meet all eligibility criteria.
Table 1 outlines all procedures to be conducted during the baseline visit (Visit 2) with further 
clarification provided below:

For subjects with >32 days since the safety measurements at the screening visit (Visit 1) were 
collected, an abbreviated physical examination, 12-lead ECG in triplicate, serum pregnancy 
test, urine drug screen, and all clinical laboratory tests must be repeated, and the results 
reviewed by the investigator prior to the subject being enrolled. 

Blood pressure and pulse will be collected 3 times (with approximately 2 minutes in between 
each collection) using the age-appropriate cuff during the visit. 

If >32 days since the screening visit, 3 ECGs will be taken, with approximately 3 minutes in 
between each one, to ensure appropriate baseline intervals are established. The investigator 
will perform the initial interpretation of the ECG immediately after collection to ensure the 
safety of each subject and to determine eligibility. The ECG tracing will be sent to the central 
reader for analysis. Upon review of the report from the central reader, the investigator will 
re-evaluate the clinical significance of the ECG in light of other safety data for the subject. If 
abnormal and significant results are observed following assessment by the central reader, the 
investigator, in consultation with the appointed CRO Medical Monitor, will confirm the 
subject’s continued participation in this study.

Safety Follow-up Period
The follow-up period for this protocol is 7 days (+2 days) from the last dose of the 
investigational product. 
At the end of this period there will be a telephone call initiated by the site staff to query for 
SAEs, AEs, and concomitant treatments. All AEs and SAEs that are not resolved at the time of 
this contact will be followed to closure (see Section 8.1).
7.1.4
Additional Care of Subjects After the Study
Subjects who have completed the study at Visit 6 may be evaluated for eligibility to enter a 
long-term safety study of SHP465.
The subject’s primary care physician will be responsible for determining the appropriate and 
available treatment options upon study completion for subjects who did not enroll into the 
long-term safety study of SHP465. However, to maintain the integrity of the study, subjects will 
not be unblinded to treatment assignment at the end of their participation in the study. 
7.2
Study Evaluations and Procedures
The individual indicated in each scale description will perform all assessments listed below. 
Assessments are to be performed according to the schedule shown in Table 1.
Care must be taken by the site personnel or the investigator to fully explain the scale prior to 
completion.
If the subject terminates treatment early, all assessments listed in Table 1 for Visit 6/ET and the 
safety follow-up call should be completed. Whenever possible, raters (including parent/LAR, and 
the investigator or site designee) observing the subject’s behavior should be consistent from visit 
to visit throughout the study.

Screening Assessments
7.2.2.1
Mini International Neuropsychiatric Interview for Children and Adolescents
The MINI-KID is a structured clinical diagnostic interview designed to assess the presence of 
psychiatric disorders in children and adolescents in a way that is comprehensive and concise. It 
follows the structure and format of the adult version of the interview and is organized in 
diagnostic sections or modules. 
Using branching tree logic, the instrument asks 2 to 4 screening questions for each disorder.

Additional symptom questions within each disorder section are asked only if the screen questions 
are positively endorsed. The MINI is the structured psychiatric interview of choice for 
psychiatric evaluation and outcome tracking in clinical psychopharmacology trials and 
epidemiological studies. In a validation study (Sheehan et al., 2010), the MINI-KID generated 
reliable and valid psychiatric diagnoses for children and adolescents and does so in a third of the 
time as the Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime 
Version. The MINI-KID Standard Version for DSM-5 assesses the 30 most common and 
clinically relevant disorders or disorder subtypes in pediatric mental health. With this version, 
the child and parent are interviewed together. The MINI-KID should be completed by an 
individual who has experience in the evaluation of pediatric patients with ADHD and the scale, 
and may include physicians, or licensed psychologists/clinicians. All individuals performing this 
assessment must be preapproved by the sponsor or designee.
7.2.3
Efficacy
7.2.3.1
Attention-deficit/Hyperactivity Rating Scale 
The ADHD-RS-5 Child, Home Version (DuPaul et al. 2016), the primary efficacy measure, is 
completed by the clinician and will be administered at baseline (Visit 2) and each subsequent 
visit up to and including Visit 6/ET to capture the ADHD symptoms within each study period. 
The ADHD rating scale was developed to measure the behaviors of children with ADHD and is 
commonly used in clinical studies of ADHD (Buitelaar et al. 2007; Döpfner et al. 2006;
Kratochvil et al. 2001; Michelson et al. 2001; Spencer et al. 2001). The ADHD-RS-5 consists of 
18 items designed to reflect current symptomatology of ADHD based on DSM-5 criteria. Each 
item is scored on a 4-point scale ranging from 0 (reflecting no symptoms) to 3 (reflecting severe 
symptoms) with total scores ranging from 0-54. The 18 items may be grouped into 2 subscales: 
hyperactivity/impulsivity (9 items) and inattentiveness (9 items).
The ADHD-RS-5 should be completed by a clinician experienced in the evaluation of children 
with ADHD. Since the ADHD-RS-5 is an important measure for guidance in dosing decisions, 
the ADHD-RS-5 must be performed by an individual who is experienced with the scale. All 
individuals performing this assessment must be pre-approved by the sponsor or designee.
The title, version, and date of the ADHD-RS-5 used in this study are included in Appendix 3.
7.2.3.2
Clinical Global Impression
The Clinical Global Impression Scale (Guy 1976) permits a global evaluation of the subject’s 
severity and improvement over time. The Clinical Global Impression has been used extensively 
in clinical studies of ADHD (Michelson et al. 2001; Weiss et al. 2005; Wilens et al. 2001).
The investigator will perform the CGI-S to rate the severity of a subject’s condition on a 7-point 
scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill subjects) at the 
baseline visit (Visit 2). Additionally at the baseline visit, the investigator should establish 3 target 
areas of improvement with the subject and the subject’s parent/LAR. 
To generate the targets, an open-ended question such as “If this program of treatment works for 

Shire
CONFIDENTIAL
Page 47
Study Protocol 
SHP465-309 
07 September 2017
your child, what things do you hope he/she will be doing better?” should be asked. Ratings will 
be completed with respect to ADHD symptoms.
At each visit from Visit 3 up to and including Visit 6/ET, the investigator will assess the 
subject’s improvement relative to the 3 target areas of improvement recorded at the baseline visit 
(Visit 2), on the CGI-I, a 7-point scale ranging from 1 (very much improved) to 7 (very much 
worse).
The CGI-S and CGI-I should be completed by a clinician experienced in the evaluation of 
children with ADHD. Since the CGI-I is an important measure for guidance in dosing decisions, 
the CGI-I must be performed by a principal investigator or sub-investigator who is 
medically/clinically responsible for the subject and experienced with the scale. All individuals 
performing this assessment must be pre-approved by the sponsor or designee.
The title, version, and date of the CGI-S and the CGI-I used in this study are included in 
Appendix 3. 
7.2.4
Safety
The name and address of each third party vendor (eg, clinical laboratory) used in this study will 
be maintained in the investigator’s and sponsor’s files.
7.2.4.1
Medical and Medication History
The investigator will perform a complete medical history at the screening visit (Visit 1), 
including a medication history, and record all information gathered. The investigator must record 
all clinically or medically relevant information regardless of how much time has elapsed since 
the date of diagnosis.
With the subject and parent/LAR consent, medical records from other treatment providers should 
be requested. 
7.2.4.2
Physical Examination
A full physical examination will be performed at the screening visit (Visit 1) and Visit 6/ET. 
Additionally, an abbreviated physical examination is required at the baseline visit (Visit 2) if 
more than 32 days have elapsed since the physical examination completed as part of the 
screening visit (Visit 1) was performed. The physical examination will be performed by a 
qualified, licensed individual per local requirements (eg, physician, physician assistant, or nurse 
practitioner).
A full physical examination is composed of a review of the following body systems:

General appearance

Skin

Head, Eyes, Ears, Nose, and Throat

If an abbreviated physical examination is required at the baseline visit (Visit 2), a review of the 
body systems will include the following:

General Appearance

Respiratory

Cardiovascular
Abnormalities identified at the screening visit (Visit 1) will be documented in the subject’s 
source documents. Changes after the screening visit (Visit 1) will be captured as AEs, as 
determined by the investigator.
7.2.4.3
Adverse Event Collection
At each study visit, parent/LAR and/or subject will be questioned in a general way to ascertain if 
AEs have occurred since the previous visit (eg, “Have you had any health problems since your 
last visit?”). Adverse events are collected from the time informed consent is signed. (Refer to 
Section 8.) This information should be collected prior to the completion of assessments at all 
study visits. In addition, any symptoms/conditions reported during assessments and deemed to be 
clinically significant by the investigator will be assessed as AEs.
7.2.4.4
Vital Signs (Including Height and Weight)
Measurements of oral or tympanic temperature and sitting respiratory rate will be performed at 
the screening visit (Visit 1) and/or baseline (Visit 2) only. 
Measurements of sitting systolic and diastolic blood pressure and pulse will be performed at each 
visit to the site. Blood pressure, pulse, and respiratory rate will be determined after subjects have 
remained seated for a minimum of 3 minutes.
Blood pressure will be determined by an age-appropriate cuff (the same unit and same arm 
should be used throughout the study). A blood pressure cuff appropriate for the subject’s arm 
length and girth should be used for all blood pressure measurements. The age-appropriate cuff 
should be approximately two-thirds the length/width of the subject’s arm (from elbow to 
shoulder). All blood pressure measurements should be taken using the same arm and be 
performed by the same site personnel (if possible) throughout the study. 
The age-appropriate cuff will obtain 3 measurements with approximately 2 minutes in between 
each collection for blood pressure and pulse and report the average of the 3 measurements for

each parameter. The 3 individual measurements, time collected, and averaged reading should be 
recorded in the source. 
Height will be captured at the screening visit (Visit 1). A calibrated stadiometer must be used for 
all height measurements. Height should be measured in inches or centimeters without shoes with 
the subject standing on a flat surface and with chin parallel to the floor. The body should be 
straight but not rigid. 
Weight will be captured at each visit to the site. The same calibrated scale should be used for all 
weight measurements. Weight should be measured in pounds or kilograms without shoes and 
with light clothing and should be recorded to the nearest 0.1 pound or 0.1 kilogram. 
Any clinically significant deviations from screening (Visit 1) vital signs which are deemed 
clinically significant in the opinion of the investigator are to be recorded as an AE.
7.2.4.5
Clinical Laboratory Evaluations
All clinical laboratory assays will be performed according to the laboratory’s normal procedures. 
Reference ranges are to be supplied by the laboratory and will be used to assess the clinical 
laboratory data for clinical significance and out-of-range pathological changes. The investigator 
should assess out-of-range clinical laboratory values for clinical significance, indicating if the 
value(s) is/are not clinically significant or clinically significant. Abnormal clinical laboratory 
values, which are unexpected or not explained by the subject’s clinical condition, may, at the 
discretion of the investigator or sponsor, be repeated as soon as possible until confirmed, 
explained, or resolved.
Clinical laboratory assessments will be performed at the screening visit (Visit 1) and Visit 6/ET. 
Additionally, clinical laboratory tests are required to be repeated prior to the baseline visit (Visit 
2) with results reviewed before enrolling the subject in the study if more than 32 days have 
elapsed since the clinical laboratory assessments completed as part of the screening visit (Visit 1) 
were performed. 
The following clinical laboratory assessments will be performed:

7.2.4.6
Urine Drug Screen
A urine drug and alcohol screen will be conducted at the screening visit (Visit 1). As a reminder, 
a urine drug screen should be repeated prior to the baseline visit (Visit 2) if more than 32 days 
have elapsed since the screening visit (Visit 1).
Urine samples (~10 mL) will be collected for this testing and will be evaluated at the central 
laboratory. The following drugs/drug classes will be tested:
Urine Drug Screen
Cocaine
Cannabinoids
Phencyclidine
d-amphetamine
Benzodiazepines class
Barbiturates class
Opiates class
Propoxyphene
Methaqualone
Methadone
Methamphetamine
The urine drug screen must be negative at the screening visit (Visit 1) for the subject to be 
eligible to enroll in the study.
If the subject has a positive urine drug screen at the screening visit (Visit 1) that the investigator 
is able to attribute to a medication that has been prescribed to the subject, the urine drug screen 
must be repeated prior to the baseline visit (Visit 2) and must be negative so the investigator can 
verify that the disallowed medication which caused a positive result at the screening visit 
(Visit 1) has been discontinued prior to the baseline visit (Visit 2). 
7.2.4.7
Pregnancy Test
A serum -HCG pregnancy test is performed on all females of child-bearing potential at the 
screening visit (Visit 1). Additionally, the serum pregnancy test must be repeated at the baseline 
visit (Visit 2) if greater than 32 days have elapsed since the screening visit (Visit 1). The results 
must be reviewed by the investigator before the subject can be randomized. 
A urine pregnancy test is performed on all females of child-bearing potential at the baseline visit 
(Visit 2), and at the final visit (Visit 6/ET), or if pregnancy is suspected, or on withdrawal of the 
subject from the study.
7.2.4.8
Electrocardiogram 
A 12-lead ECG will be performed at the screening visit (Visit 1), Visit 4, and Visit 6/ET. At 
screening, 3 ECGs taken approximately 3 minutes apart will be collected; if >32 days have 
passed since screening, these ECGS will be collected in triplicate at Visit (Visit 2) to ensure 
appropriate baseline intervals are established. Additional ECGs may be performed during the 
study at the investigator’s discretion.  

Shire
CONFIDENTIAL
Page 52
Study Protocol 
SHP465-309 
07 September 2017
All ECGs will be performed after 3 minutes of rest using the central ECG provider’s equipment 
and will be sent to the central ECG provider electronically.
The initial interpretation of the ECG, normal or abnormal and clinical significance, will be 
performed immediately after collection to ensure the safety of each subject. An ECG tracing will 
then be evaluated by a cardiologist at a central ECG reading vendor and returned to the site with 
a determination of normal or abnormal. Upon review of the report from this vendor, the 
investigator will re-evaluate the clinical significance of the ECG while taking into consideration 
all other safety data available for the subject.
Although a central ECG reader is being used for this study, the eligibility of the subject is based 
on the investigator’s assessment of the ECG. If abnormal and significant results are observed 
following assessment by the central reader, the investigator, in consultation with the appointed 
CRO medical monitor, reconfirms subject eligibility to continue.
All ECGs transmitted to the central ECG reader will be analyzed. If the central ECG reader 
receives multiple ECGs, the first readable ECGs will be analyzed as the scheduled ECG. Every 
ECG transmitted to the central ECG reader will have corresponding source document data 
collected. No ECG should be deleted by study site personnel. All ECGs must be transmitted to 
the central provider regardless of quality, results, or number of ECGs taken at a respective visit.
7.2.4.9
Children’s Sleep Habits Questionnaire  
The CSHQ is a tool designed to screen for the most common sleep problems in children and 
consists of 33 items for scoring and several extra items intended to provide administrators with 
other potentially useful information about respondents. The instrument evaluates the child’s 
sleep based on behavior within 8 different subscales: bedtime resistance, sleep onset delay, sleep 
duration, sleep anxiety, night wakings, parasomnias, sleep disordered breathing, and daytime 
sleepiness. The CSHQ will be conducted at each visit to the site starting with the baseline visit 
(Visit 2) and will be completed by the subject’s parent/LAR. 
7.2.4.10 Post Sleep Questionnaire 
The PSQ is a 7-item questionnaire typically used to assess sleep quality with pharmacologic 
treatment. The questionnaire collects data on average time to sleep, sleep latency, frequency of 
interrupted sleep, duration of interrupted sleep, total sleep time and sleep quality over the last 
week. The PSQ will be completed by the parent/LAR with the subject and the responses will be 
reviewed by the clinician during the study visit. The PSQ will be completed at Baseline (Visit 2), 
and each visit through Visit 6/ET. The title, version, and date of the PSQ version used in this 
study are included in Appendix 3.
7.2.4.11 Columbia-Suicide Severity Rating Scale 
The C-SSRS (Posner 2007) is a semi-structured interview that captures the occurrence, severity, 
and frequency of suicide-related thoughts and behaviors during the assessment period. The 
interview includes definitions and suggested questions to solicit the type of information needed 
to determine if a suicide-related thought or behavior occurred.

Shire
CONFIDENTIAL
Page 53
Study Protocol 
SHP465-309 
07 September 2017
The C-SSRS contains 2 required items pertaining to suicidal ideation, 4 required items pertaining 
to suicidal behavior, and 1 required item pertaining to nonsuicidal self-injurious behavior. There 
are 8 additional suicidal ideation items and 2 additional suicidal behavior items which are 
completed in cases of positive responses for other items, as well as 2 items for completed suicide 
and suicide behavior present during the interview. Thus, there is a maximum of 19 items to be 
completed.
The C-SSRS must be performed by an individual who is medically responsible for the subject. 
All individuals performing this assessment must be preapproved by the sponsor or delegated 
vendor.
Two versions of the C-SSRS are used in this study:

The “baseline” version will be administered at the screening visit (Visit 1) and will be 
completed for all subjects.

The “since last visit” version will be completed for all subjects at all study visits after the 
screening visit (Visit 1).
The title, version, and date of the C-SSRS “Baseline” version and the C-SSRS “since last visit” 
version used in this study are included in Appendix 3.
7.2.4.12 Suitability of the Subject to Remain in the Study 
At each visit (except for Visit 6/ET) starting with the baseline visit (Visit 2), the investigator will
assess the subject’s ability to continue in the study. The investigator or a medically qualified
designee will review all available safety information (including sleep behavior, weight and BMI) 
and will evaluate for the presence of insomnia or decreased appetite potentially leading to weight 
loss. In cases where the subject has clinically significant decreases in appetite or insomnia, the 
investigator should intervene as necessary based on clinical judgment (eg, diet, behavioral 
interventions, sleep hygiene) and consider discontinuation of treatment if necessary. In any cases 
where a subject has clinically significant and persistent sleep difficulties (eg, the CSHQ score of 
≥41 for 2 consecutive weeks since the beginning of treatment) or has had ≥7% weight loss the 
investigator must discuss the case with the medical monitor and assess whether it’s in the best 
interest for the subject to remain in the study. The evaluation and decision should also be clearly 
documented in the subject’s source notes.
As part of the assessment of the subject’s suitability to remain in the study the investigator 
should also assess the subject’s current potential for suicide, suicidal ideation, self-harm, or harm 
to others, as well as psychiatric disorders. The investigator should make this assessment by 
conducting a clinical interview with the subject and by reviewing of all other relevant sources 
available, including results of the C-SSRS. Any subject who has 1 or more positive responses 
must undergo further evaluation to ensure that they are not in any way at risk. As part of this 
assessment, if appropriate, the investigator should discuss risk factors for suicide with the 
subject. Where a subject has suffered an accidental injury, the investigator should ensure that this 
was a true accidental injury, rather than an episode of self-harming or a suicide attempt.

The investigator should pay particular attention to:

Any ‘yes’ response to Items 2, 3, 4, or 5 on the C-SSRS or any suicidal behavior.
The subject’s source notes should clearly document that the assessment of continued suitability 
including assessment of the subject’s appetite, weight loss, insomnia and current potential risk of 
suicide, suicidal ideation, feelings of hopelessness, drug use, self-harm, or harm to others has 
taken place and should contain the decision on whether the subject is suitable to continue in the 
study.

ADVERSE AND SERIOUS ADVERSE EVENTS ASSESSMENT
8.1
Definition of Adverse Events, Period of Observation, Recording of Adverse Events
An AE is any untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product and that does not necessarily have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product (ICH 
Guidance E2A 1995). 
All AEs are collected from the time the informed consent is signed until the defined follow-up 
period stated in Section 7.1.3. This includes events occurring during the screening phase of the 
study, regardless of whether or not investigational product is administered. Where possible, a 
diagnosis rather than a list of symptoms should be recorded. If a diagnosis has not been made, 
then each symptom should be listed individually. All AEs should be captured on the appropriate 
AE pages in the CRF and in source documents. In addition to untoward AEs, unexpected 
benefits outside the investigational product indication should also be captured on the AE CRF.
All AEs must be followed to closure (the subject’s health has returned to his/her baseline status 
or all variables have returned to normal), regardless of whether the subject is still participating in 
the study. Closure indicates that an outcome is reached, stabilization achieved (the investigator 
does not expect any further improvement or worsening of the event), or the event is otherwise 
explained. When appropriate, medical tests and examinations are performed so that resolution of 
event(s) can be documented.
8.1.1
Severity Categorization
The severity of AEs must be recorded during the course of the event including the start and stop 
dates for each change in severity. An event that changes in severity should be captured as a new 
event. Worsening of pretreatment events, after initiation of investigational product, must be 
recorded as new AEs (for example, if a subject experiences mild intermittent dyspepsia prior to 
dosing of investigational product, but the dyspepsia becomes severe and more frequent after first 
dose of investigational product has been administered, a new AE of severe dyspepsia [with the 
appropriate date of onset] is recorded on the appropriate CRF).
The medical assessment of severity is determined by using the following definitions:
Mild:
A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual 
activities of daily living.
Moderate:
A type of AE that is usually alleviated with specific therapeutic intervention. The 
event interferes with usual activities of daily living, causing discomfort but poses 
no significant or permanent risk of harm to the research subject.

Shire
CONFIDENTIAL
Page 56
Study Protocol 
SHP465-309 
07 September 2017
Severe:
A type of AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention.
8.1.2
Relationship Categorization
A physician/investigator must make the assessment of relationship to investigational product for 
each AE. The investigator should decide whether, in his or her medical judgment, there is a 
reasonable possibility that the event may have been caused by the investigational product. If 
there is no valid reason for suggesting a relationship, then the AE should be classified as “not 
related”. Otherwise, if there is any valid reason, even if undetermined or untested, for suspecting 
a possible cause-and-effect relationship between the investigational product and the occurrence 
of the AE, then the AE should be considered “related”. The causality assessment must be 
documented in the source document.
The following additional guidance may be helpful:
Term
Relationship Definition
Related
The temporal relationship between the event and the administration of the 
investigational product is compelling and/or follows a known or suspected response 
pattern to that product, and the event cannot be explained by the subject’s medical 
condition, other therapies, or accident.
Not Related
The event can be readily explained by other factors such as the subject’s underlying 
medical condition, concomitant therapy, or accident and no plausible temporal or 
biologic relationship exists between the investigational product and the event.
8.1.3
Outcome Categorization
The outcome of AEs must be recorded during the course of the study on the CRF. Outcomes are 
as follows:

Fatal

Not Recovered/Not Resolved

Recovered/Resolved

Recovered/Resolved With Sequelae 

Recovering/Resolving

Unknown
8.1.4
Symptoms of the Disease Under Study
Symptoms of the disease under study should not be classed as AEs as long as they are within the 
normal day-to-day fluctuation or expected progression of the disease and are part of the efficacy 
data to be collected in the study; however, significant worsening of the symptoms should be 
recorded as an AE.

Shire
CONFIDENTIAL

Study Protocol 
SHP465-309 
07 September 2017
8.1.5
Clinical Laboratory and Other Safety Evaluations
A change in the value of a clinical laboratory, vital sign, or ECG assessment can represent an AE 
if the change is clinically relevant or if, during treatment with the investigational product, a shift 
of a parameter is observed from a normal value to an abnormal value, or a further worsening of 
an already abnormal value. When evaluating such changes, the extent of deviation from the 
reference range, the duration until return to the reference range, either while continuing treatment 
or after the end of treatment with the investigational product, and the range of variation of the 
respective parameter within its reference range, must be taken into consideration.
If, at the end of the treatment phase, there are abnormal clinical laboratory, vital sign, or ECG 
values which were not present at the pretreatment value observed closest to the start of study 
treatment, further investigations should be performed until the values return to within the 
reference range or until a plausible explanation (eg, concomitant disease) is found for the 
abnormal values.
The investigator should decide, based on the above criteria and the clinical condition of a 
subject, whether a change in a clinical laboratory, vital sign, or ECG parameter is clinically 
significant and therefore represents an AE.
8.1.6
Pregnancy
All pregnancies are to be reported from the time informed consent is signed until the defined 
follow-up period stated in Section 7.1.3.
Any report of pregnancy for any female study participant must be reported within 24 hours to the 
Shire Pharmacovigilance Department using the Shire Investigational and Marketed Products 
Pregnancy Report Form. A copy of the Shire Investigational and Marketed Products Pregnancy 
Report Form (and any applicable follow-up reports) must also be sent to the CRO/Shire Medical 
Monitor using the details specified in the emergency contact information section of the protocol. 
The pregnant female study participant must be withdrawn from the study.
Every effort should be made to gather information regarding the pregnancy outcome and 
condition of the infant. It is the responsibility of the investigator to obtain this information within 
30 calendar days after the initial notification and approximately 30 calendar days post partum. 
Pregnancy complications such as spontaneous abortion/miscarriage or congenital abnormality 
are considered SAEs and must be reported using the Shire Clinical Trial Serious Adverse Event 
Form. Note:  An elective abortion is not considered an SAE.
In addition to the above, if the investigator determines that the pregnancy meets serious criteria, 
it must be reported as an SAE using the Shire Clinical Trial Serious Adverse Event Form as well 
as the Shire Investigational and Marketed Products Pregnancy Report Form. The test date of the 
first positive serum/urine -HCG test or ultrasound result will determine the pregnancy onset 
date.

Abuse, Misuse, Overdose, and Medication Error
Abuse, misuse, overdose, or medication error (as defined below) must be reported to the sponsor 
according to the SAE reporting procedure whether or not they result in an AE/SAE as described 
in Section 8.2. Note: The 24-hour reporting requirement for SAEs does not apply to reports of 
abuse, misuse, overdose, or medication errors unless these result in an SAE. 
The categories below are not mutually exclusive; the event can meet more than 1 category.

Abuse – Persistent or sporadic intentional intake of investigational product when used for a 
nonmedical purpose (eg, to alter one’s state of consciousness or get high) in a manner that 
may be detrimental to the individual and/or society.

Misuse – Intentional use of investigational product other than as directed or indicated at 
any dose (Note: this includes a situation where the investigational product is not used as

Serious Adverse Event Procedures
8.2.1
Reference Safety Information
The reference for safety information for this study is the SHP465 investigator’s brochure which 
the sponsor has provided under separate cover to all investigators.
8.2.2
Reporting Procedures
All initial and follow-up SAE reports must be reported by the investigator to the Shire 
Pharmacovigilance Department and the CRO/Shire Medical Monitor within 24 hours of the 
first awareness of the event.

Study Protocol 
SHP465-309 
07 September 2017
Note: The 24-hour reporting requirement for SAEs does not apply to reports of abuse, misuse, 
overdose, or medication errors (see Section 8.1.7) unless they result in an SAE. 
The investigator must complete, sign, and date the Shire Clinical Trial Serious Adverse Event 
Form and verify the accuracy of the information recorded on the form with the corresponding 
source documents (Note:  Source documents are not to be sent unless requested) and fax or 
e-mail the form to the Shire Pharmacovigilance Department. A copy of the Shire Clinical Trial 
Serious Adverse Event Form (and any applicable follow-up reports) must also be sent to the 
CRO/Shire Medical Monitor using the details specified in the emergency contact information 
section of the protocol.
8.2.3
Serious Adverse Event Definition
An SAE is any untoward medical occurrence (whether considered to be related to investigational 
product or not) that at any dose:

Results in death.

Is life-threatening. Note: The term ‘life-threatening’ in the definition of “serious” refers to 
an event in which the subject was at risk of death at the time of the event; it does not refer 
to an event which hypothetically might have caused death if it was more severe.

Requires inpatient hospitalization or prolongation of existing hospitalization. Note: 
Hospitalizations, which are the result of elective or previously scheduled surgery for 
pre-existing conditions, which have not worsened after initiation of treatment, should not 
be classified as SAEs. For example, an admission for a previously scheduled ventral hernia 
repair would not be classified as an SAE; however, complication(s) resulting from a 
hospitalization for an elective or previously scheduled surgery that meet(s) serious criteria 
must be reported as SAE(s).

Results in persistent or significant disability/incapacity.

Is a congenital abnormality/birth defect.

Is an important medical event. Note: Important medical events that may not result in death, 
be life-threatening, or require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the subject and may require medical or 
surgical intervention to prevent 1 of the outcomes listed in this definition. Examples of 
such medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home; blood dyscrasias or convulsions that do not result in inpatient 
hospitalization; or the development of drug dependency or drug abuse. 
8.2.4
Serious Adverse Event Collection Time Frame
All SAEs (regardless of relationship to study) are collected from the time the subject signs the 
informed consent until the defined follow-up period stated in Section 7.1.3, and must be reported 
to the Shire Pharmacovigilance Department and the CRO/Shire Medical Monitor within 24 hours 
of the first awareness of the event. 

Shire
CONFIDENTIAL
Page 60
Study Protocol 
SHP465-309 
07 September 2017
In addition, any SAE(s) considered “related” to the investigational product and discovered by the 
investigator at any interval after the study has completed must be reported to the Shire 
Pharmacovigilance Department within 24 hours of the first awareness of the event.
8.2.5
Serious Adverse Event Onset and Resolution Dates
The onset date of the SAE is defined as the date the event meets serious criteria. The resolution 
date is the date the event no longer meets serious criteria, the date the symptoms resolve, or the 
event is considered chronic. In the case of hospitalizations, the hospital admission and discharge 
dates are considered the onset and resolution dates, respectively.
In addition, any signs or symptoms reported by the subject after signing the informed consent
form, or leading up to the onset date of the SAE, or following the resolution date of the SAE, 
must be recorded as an AE, if appropriate.
8.2.6
Fatal Outcome
Any SAE that results in the subject’s death (ie, the SAE was noted as the primary cause of death) 
must have fatal checked as an outcome with the date of death recorded as the resolution date. For 
all other events ongoing at the time of death that did not contribute to the subject’s death, the 
outcome should be considered not resolved, without a resolution date recorded.
For any SAE that results in the subject’s death or any ongoing events at the time of death, the 
action taken with the investigational product should be recorded as “dose not changed” or “not 
applicable” (if the subject never received investigational product).
8.2.7
Regulatory Agency, Institutional Review Board, Ethics Committee, and Site 
Reporting
The sponsor and the clinical CRO is responsible for notifying the relevant regulatory authorities 
and central IRBs of related, unexpected SAEs.
In addition the clinical CRO is responsible for notifying active sites of all related, unexpected 
SAEs occurring during all interventional studies across the SHP465 program. 
The investigator is responsible for notifying the local IRB, local EC, or the relevant local 
regulatory authority of all SAEs that occur at his or her site as required.

DATA MANAGEMENT AND STATISTICAL METHODS
9.1
Data Collection
The investigators’ authorized site personnel must enter the information required by the protocol 
on the CRF. A study monitor will visit each site in accordance with the monitoring plan and 
review the CRF data against the source data for completeness and accuracy. Discrepancies 
between source data and data entered on the CRF will be addressed by qualified site personnel. 
When a data discrepancy warrants correction, the correction will be made by authorized site 
personnel. Data collection procedures will be discussed with the site at the site initiation visit 
and/or at the investigator’s meeting. Once a subject is randomized, it is expected that site 
personnel will complete the CRF entry as soon as possible after he subject's visit to ensure 
accuracy and completeness of data.
9.2
Clinical Data Management
Data are to be entered into a clinical database as specified in the CRO’s data management plan. 
Quality control and data validation procedures are applied to ensure the validity and accuracy of 
the clinical database.
Data are to be reviewed and checked for omissions, errors, and values requiring further 
clarification using computerized and manual procedures. Data queries requiring clarification are 
to be communicated to the site for resolution. Only authorized personnel will make corrections to 
the clinical database, and all corrections are documented in an auditable manner.
9.3
Data Handling Considerations
Data that may potentially unblind the treatment assignment (ie, investigational product serum 
concentrations, treatment allocation, and investigational product preparation/accountability data) 
will be handled with special care during the data cleaning and review process. These data will be 
handled in such a way that, prior to unblinding, any data that may unblind study team personnel 
will be presented as blinded information or otherwise will not be made available. If applicable, 
unblinded data may be made available to quality assurance representatives for the purposes of 
conducting independent drug audits. 
9.4
Statistical Analysis Process
The study will be analyzed by the sponsor or its agent. 
The SAP will provide the statistical methods and definitions for the analysis of the efficacy and 
safety data, as well as describe the approaches to be taken for summarizing other study 
information such as subject disposition, demographics and baseline characteristics, 
investigational product exposure, and prior and concomitant medications. The SAP will also 
include a description of how missing, unused, and spurious data will be addressed.

Shire
CONFIDENTIAL
Page 62
Study Protocol 
SHP465-309 
07 September 2017
The SAP will be finalized prior to unblinding to preserve the integrity of the statistical analysis 
and study conclusions. 
All statistical analyses will be performed using SAS(SAS Institute, Cary, NC 27513). 
9.5
Data Monitoring Committee
An external independent Data Monitoring Committee (DMC) was set up to review the data 
pertaining to safety and tolerability of the study therapy for the duration of this program, which 
includes studies SHP465-112, SHP465-308, and SHP465-309. The DMC will review the data 
pertaining to safety and tolerability of the study therapy. Confidentiality of the unblinded DMC 
analyses is a critical concern and to address this, an unblinded independent reporting team will 
be identified within a CRO. The independent reporting team will have no involvement in the 
conduct of the study. Further details regarding the DMC can be found in the DMC charter, which 
will be available before the administration of investigational product. 
9.6
Planned Interim Analysis
A blinded interim analysis at the late stage of the trial (when approximately 75% of all 
randomized subjects have either completed or discontinued from the study) will be performed to 
reassess the sample size in case of an underestimated variability postulated at the design stage.
Using the cumulative real data, a blinded, pooled analysis of both treatment groups for 
estimating variability will be conducted. If the re-estimated pooled standard deviation is larger 
than the 14 postulated at the design stage, the final total number of subjects to be enrolled will be 
calculated using the re-estimated pooled standard deviation together with the assumed treatment
difference of 11.9 (Friede and Kieser 2006). If the re-estimated pooled standard deviation is 
smaller than 14, the sample size will not be adjusted.
9.7
Sample Size Calculation and Power Considerations
The sample size planned at study initiation was estimated for the primary comparison of SHP465 
at 6.25 mg with placebo by using nQuery Advisor 7.0. 
Approximately 60 subjects will be randomized in a 1:1 ratio to SHP465 at 6.25 mg and placebo 
to achieve 52 completers for the study (26 in each treatment group) and 85% power for the 
primary efficacy analysis at the 2-sided 0.05 significance level. The sample size planned is 
estimated based on the primary comparison between SHP465 at 6.25 mg and placebo on the 
primary efficacy endpoint, change from baseline in ADHD-RS-5 total score at Visit 6 (Week 4). 
Assumptions for the calculation include the true mean difference of 11.9 with the common 
standard deviation (SD) of 14 for the primary efficacy endpoint, for an effect size of 0.85, and a 
dropout rate of 15%.

Shire
CONFIDENTIAL
Page 63
Study Protocol 
SHP465-309 
07 September 2017
The effect size of 0.85 is low compared with that observed in recently completed study 
(SHP465-305) of children and adolescents aged 6-17 years with ADHD treated with SHP465. 
The SHP465-305 study yielded an effect size of 0.93 in children aged 6-12 years (101 subjects).
9.8
Study Population
The screened set will consist of all subjects who have provided consent.
The randomized set will consist of all subjects in the screened set for whom a randomization 
number has been assigned.
The safety set will consist of all subjects in the randomized set who have taken at least 1 dose of 
investigational product. 
The full analysis set (FAS) will consist of all subjects in the safety set who have at least 
1 post-dose ADHD-RS-5 Total Score.
9.9
Efficacy Analyses
All efficacy analyses will be performed using the FAS. All statistical tests will be 2-sided 
hypothesis tests. Also, all confidence intervals will be 2 sided with 95% coverage, unless stated 
otherwise. The primary and key secondary analyses will be conducted based on the entire age 
group in the FAS.
Handling of missing data rules will be described in the SAP.
9.9.1
Primary Efficacy Endpoint
The primary efficacy endpoint is defined as the change from baseline of the ADHD-RS-5 Total 
Score at Visit 6 (Week 4). The baseline ADHD-RS-5 Total Score is the last value obtained prior 
to taking the first dose of investigational product, usually at Visit 2. 
The primary efficacy analysis will be conducted over the FAS for the change from baseline in 
the ADHD-RS-5 Total Scores, including all assessments from Visit 3 (Week 1) up to Visit 6 
(Week 4). The primary efficacy endpoint will be analyzed by using the linear mixed-effects 
model for repeated measures (MMRM) with treatment group, visit, age group (6-8 years vs. 
9-12 years), and the interaction of treatment group with visit as factors, baseline ADHD-RS-5 
Total Score as a covariate, and the interaction of baseline ADHD-RS-5 Total Score with visit 
adjusted in the model. The primary contrast of interest will be at Visit 6 (Week 4) for SHP465 
6.25 mg compared with placebo at the 2-tailed significance level of 0.05.
The null and alternative hypotheses of the primary efficacy analysis will be the following:

Null hypothesis: There is no difference in primary endpoint mean change from baseline at 
Visit 6 (Week 4) in ADHD-RS-5 total scores between SHP465 6.25 mg and placebo

Alternative hypothesis: There is a difference in primary endpoint mean change from baseline 
at Visit 6 (Week 4) in ADHD-RS-5 total scores between SHP465 6.25 mg and placebo.

Shire

Study Protocol 
SHP465-309

As the primary efficacy analysis (MMRM) relies on the assumption that the missing data 
mechanism follows the MAR (missing-at-random) scenario, sensitivity analyses to examine the 
effect of data that are missing not at random and the robustness on the results of the primary 
analysis will be conducted. One sensitivity analysis model assumes that a subject on SHP465 
6.25 mg treatment with missing data follows the distribution of the placebo responses, ie, the 
means and the intrasubject correlations based on the placebo responses will apply. Another 
sensitivity analysis model assumes that subjects who drop out perform worse than MAR by a 
penalty. The details of the sensitivity analysis methods will be specified in the SAP. 
The observed and change from baseline ADHD-RS-5 Total Score will be summarized at each 
applicable visit using the number of subjects, mean, standard deviation, median, minimum, and 
maximum values.
9.9.2
Key Secondary Efficacy Endpoints
The key secondary efficacy endpoint, CGI-I, will be analyzed using the same analysis method 
(MMRM) as for the primary efficacy endpoint. The baseline CGI-S score will be used as the 
covariate. The primary contrast of interest will be at Visit 6 (Week 4) for SHP465 6.25 mg
compared with placebo at the 2-tailed significance level of 0.05. Appropriate sensitivity analyses 
to explore the effect of data that are missing not at random on the results of the key secondary 
efficacy analysis will be specified in the SAP.
The CGI-I will be summarized at each applicable visit using the number of subjects, mean, 
standard deviation, median, minimum, and maximum values.
The key secondary efficacy measurement will also be analyzed using the proportion of subjects 
with an “improved” CGI-I measurement at Visit 6/ET (Week 4/ET). The CGI-I categories will 
be dichotomized into 2 categories, “very much improved” and “much improved” classified as 
“improved” and all other assessed categories grouped together as “not improved”. If missing data 
exist at the Visit 6 (Week 4) visit, the visit will be imputed by carrying forward the last post 
baseline observation value. The secondary efficacy analysis for the dichotomized CGI-I will be 
conducted to compare SHP465 6.25 mg and placebo on the FAS for the “improved” rate using a 
Cochran-Mantel-Haenszel test stratified by age group and CGI-S value at baseline. 
The observed and dichotomized CGI-I values will be summarized at each applicable visit using 
number of subjects and percentages.
In order to protect the study-wide Type I error at the 2-sided 0.05 level for testing across the 
primary and the key secondary hypotheses, the Fixed-Sequence Test procedure will be applied. 
The hypotheses will be tested in order of the primary (ADHD-RS-5 Total Score) and then the 
key secondary (CGI-I), if significant for the primary, each at the 2-sided 0.05 significance level. 
Both tests in the sequence are based on the MMRM.

Exploratory Efficacy Endpoints
Each ADHD-RS-5 subscale will be analyzed using a similar model as the primary efficacy 
endpoint and summarized descriptively at each visit by treatment group.
Treatment effect of SHP465 6.25 mg on primary and key secondary measures will be 
estimated using a similar model as the primary efficacy endpoint for each age group (6-8 years 
vs. 9-12 years), sex, race (white and nonwhite), and ethnicity subgroup.
The primary and key secondary data will be descriptively summarized by treatment within each 
sex, race (white and nonwhite), and ethnicity subgroup.
9.10 Safety Analyses
The safety data will be analyzed on the safety set. Safety endpoints include the occurrence of 
TEAEs, vital signs (systolic and diastolic blood pressure, pulse), BMI and weight, ECG results, 
clinical laboratory test results, and responses to CSHQ and C-SSRS.
Exposure to investigational product will be summarized.
Adverse events will be coded using the agreed upon version of the Medical Dictionary for 
Regulatory Activities. Treatment-emergent adverse events are defined as AEs that start or 
deteriorate on or after the date of the first dose of investigational product and no later than 3 days 
following the last dose of investigational product in the double-blind phase.
The number of events, incidence, and percentage of TEAEs will be calculated overall, by SOC, 
by preferred term, and by treatment group. Treatment-emergent adverse events will be further 
summarized by severity and relationship to investigational product. Adverse events related to 
investigational product, AEs leading to withdrawal, SAEs, and deaths will be similarly 
summarized/listed.
Vital signs (systolic and diastolic blood pressure, and pulse), weight, height, and BMI including 
potentially clinically important vital signs will be summarized by treatment and visit using the 
appropriate descriptive statistics.
The ECG results including potentially clinically important results will be summarized by 
treatment and visit. 
Clinical laboratory test results will be descriptively presented by treatment group for each visit. 
Shifts of clinical laboratory abnormality from baseline to Visit 6/ET will be presented. Number 
and percent of subjects with potentially clinically important laboratory values will be presented 
by treatment group.

standard deviation, median, and minimum and maximum values. Categorical values, e.g., quality 
of sleep, will be summarized using number of observations and percentages. Detailed analyses of 
the PSQ will be described in the SAP.
The CSHQ results will be summarized by treatment and visit using appropriate descriptive 
statistics.  Detailed analyses of the CSHQ will be described in the SAP.
The C-SSRS results will be summarized and listings of the C-SSRS data will be provided for 
subjects with a positive response.
As the exploratory safety endpoint, the safety data on TEAEs will also be descriptively 
summarized by treatment within each age group (6-8 years vs. 9-12 years), sex, race (white and 
nonwhite), and ethnicity subgroup.
A listing of the C-SSRS data will be provided for subjects with a positive response. A listing of 
clinical laboratory data will be presented for all subjects.
As the exploratory safety endpoints, the safety data on TEAEs, vital signs, ECGs, clinical 
laboratory test results, PSQ and CSHQ will also be descriptively summarized by treatment 
within each age group.

Study Protocol 
SHP465-309 
07 September 2017
Within the source documents, site personnel should document instruction of and understanding 
by the parent/LAR/caregiver of the safe, responsible storage and administration of 
investigational product to the study subject.
The principal investigator provides the sponsor with a copy of the consent form and assent form 
where applicable which was reviewed by the IRB/EC and which received their favorable
opinion/approval. A copy of the IRB/EC’s written favorable opinion/approval of these 
documents must be provided to the sponsor, prior to the start of the study unless it is agreed to 
and documented (abiding by regulatory guidelines and national provisions) prior to study start 
that another party (ie, sponsor or coordinating principal investigator) is responsible for this 
action. Additionally, if the IRB/EC requires modification of the sample subject information and 
consent document provided by the sponsor, the documentation supporting this requirement must 
be provided to the sponsor.
10.3.2
Institutional Review Board or Ethics Committee
It is the responsibility of the investigator to submit this protocol, the informed consent document 
(approved by the sponsor or their designee), relevant supporting information and all types of 
subject recruitment information to the IRB/EC for review, and all must be approved prior to site 
initiation.
Responsibility for coordinating with IRBs/ECs is defined in the investigator agreement.
Prior to implementing changes in the study, the sponsor and the IRB/EC must approve any 
revisions of all informed consent documents and amendments to the protocol unless there is a 
subject safety issue.
Investigational product supplies will not be released until the sponsor has received written 
IRB/EC approval of and copies of revised documents.
The investigator is responsible for keeping the IRB/EC apprised of the progress of the study and 
of any changes made to the protocol, but in any case at least once a year; this can be done by the 
sponsor, the investigator or for multicenter studies the coordinating principal investigator. The 
investigator must also keep the local IRB/EC informed of any serious and significant AEs.
10.4
Privacy and Confidentiality
All US-based sites and laboratories or entities providing support for this study, must, where 
applicable, comply with HIPAA of 1996. A site that is not a covered entity as defined by HIPAA 
must provide documentation of this fact to the CRO.
The confidentiality of records that may be able to identify subjects will be protected in 
accordance with applicable laws, regulations, and guidelines.

Study Protocol 
SHP465-309 
07 September 2017
After subjects have consented to take part in the study, the sponsor and/or its representatives 
reviews their medical records and data collected during the study. These records and data may, in 
addition, be reviewed by others including the following: independent auditors who validate the 
data on behalf of the sponsor; third parties with whom the sponsor may develop, register, or 
market SHP465; national or local regulatory authorities; and the IRB(s) /EC(s) which gave 
approval for the study to proceed. The sponsor and/or its representatives accessing the records 
and data will take all reasonable precautions in accordance with applicable laws, regulations, and 
guidelines to maintain the confidentiality of subjects’ identities.
Subjects are assigned a unique identifying number; however, their initials and date of birth may 
also be collected and used to assist the sponsor to verify the accuracy of the data (eg, to confirm 
that laboratory results have been assigned to the correct subject). 
The results of studies – containing subjects’ unique identifying number, relevant medical 
records, and possibly initials and dates of birth – will be recorded. They may be transferred to, 
and used in, other countries which may not afford the same level of protection that applies within 
the countries where this study is conducted. The purpose of any such transfer would include: to 
support regulatory submissions, to conduct new data analyses to publish or present the study 
results, or to answer questions asked by regulatory or health authorities.
10.5
Study Results/Publication Policy
Shire will endeavor to publish the results of all qualifying, applicable, and covered studies 
according to external guidelines in a timely manner regardless of whether the outcomes are 
perceived as positive, neutral, or negative. Additionally, Shire adheres to external guidelines (eg, 
Good Publication Practices 2) when forming a publication steering committee, which is done for 
large, multicenter Phase 2-4 and certain other studies as determined by Shire. The purpose of the 
publication steering committee is to act as a noncommercial body that advises or decides on 
dissemination of scientific study data in accordance with the scope of this policy.
All publications relating to Shire products or projects must undergo appropriate technical and 
intellectual property review, with Shire agreement to publish prior to release of information. The 
review is aimed at protecting the sponsor’s proprietary information existing either at the 
commencement of the study or generated during the study. To the extent permitted by the 
publisher and copyright law, the principal investigator will own (or share with other authors) the 
copyright on his/her publications. To the extent that the principal investigator has such sole, 
joint or shared rights, the principal investigator grants the sponsor a perpetual, irrevocable, 
royalty- free license to make and distribute copies of such publications.
The term “publication” refers to any public disclosure including original research articles, review 
articles, oral presentations, abstracts and posters at medical congresses, journal supplements, 
letters to the editor, invited lectures, opinion pieces, book chapters, electronic postings on 
medical/scientific websites, or other disclosure of the study results, in printed, electronic, oral or 
other form.

Study Protocol 
SHP465-309 
07 September 2017
Subject to the terms of the paragraph below, the investigator shall have the right to publish the 
study results, and any background information provided by the sponsor that is necessary to 
include in any publication of study results, or necessary for other scholars to verify such study 
results. Notwithstanding the foregoing, no publication that incorporates the sponsor’s 
confidential information shall be submitted for publication without the sponsor’s prior written 
agreement to publish, and shall be given to the sponsor for review at least 60 days prior to 
submission for publication. If requested in writing by Shire, the institution and principal 
investigator shall withhold submission of such publication for up to an additional 60 days to 
allow for filing of a patent application.
If the study is part of a multicenter study, the first publication of the study results shall be made 
by the sponsor in conjunction with the sponsor’s presentation of a joint, multicenter publication 
of the compiled and analyzed study results. If such a multicenter publication is not submitted to a 
journal for publication by the sponsor within an 18-month period after conclusion, abandonment, 
or termination of the study at all sites, or after the sponsor confirms there shall be no multicenter 
study publication of the study results, an investigator may individually publish the study results 
from the specific site in accordance with this section. The investigator must, however, 
acknowledge in the publication the limitations of the single-site data being presented.
Unless otherwise required by the journal in which the publication appears, or the forum in which 
it is made, authorship will comply with the International Committee of Medical Journal Editors 
current standards. Participation as an investigator does not confer any rights to authorship of 
publications.

Note: To determine the eligibility of a male subject for entry in the study (based on the study 
inclusion criteria), first determine the percentile of height for the subject based on their age (as a 
whole number based on the subject’s last birthday; see the Boys’ Stature-for-age and 
Weight-for age Percentiles). For subjects who fall between 2 height percentiles, use the lower of 
the 2 percentiles. Once the subject’s age and height percentile for age are determined, use the 
table above to determine eligibility. The subject’s systolic and diastolic blood pressure readings 
at the screening visit (Visit 1) and the baseline visit (Visit 2) must not exceed the corresponding 
table value (90th blood pressure percentile) for their age and height percentile.
