Objectives: The objectives of this study are to evaluate the efficacy and safety of Aptensio XR® in 
treating ADHD in children ages 4 to under 6 years. 
Primary Efficacy Objective 
 
The primary objective of this study is to establish that an optimal dose of Aptensio XR® will 
result in a significant reduction in ADHD symptoms compared with placebo in children ages 4 to 
under 6 years. 
 
The primary efficacy measure is the comparison of the two treatment groups (optimized dose vs 
placebo) using the change in ADHD-RS-IV Total Score during the double-blind phase, i.e. the 
change from end of open label phase to end of double blind phase. 
Secondary Efficacy Objectives 
 
As with the primary efficacy objective, secondary efficacy objectives will primarily focus on the 
double-blind treatment period. 
 
Secondary efficacy measures will include the comparison of the two treatment groups (optimized 
dose vs placebo) using the following: 
 
The change in ADHD-RS-IV hyperactivity/impulsivity and inattention subscales during the 
double-blind phase

Questionnaire (CSHQ) 
Design and Investigational Plan: 
This randomized, double-blind, flexible-dose, placebo-controlled, parallel group study is designed to 
evaluate Aptensio XR® compared to placebo in preschool age children with ADHD. Male and female 
children ages 4 years, 0 months to 5 years, 8 months with a diagnosis of ADHD (combined, inattentive or 
hyperactive/impulsive) will be enrolled.  
There will be 6 phases in this study: a screening phase of up to 4 weeks, which will include washout if 
applicable, an enrollment & parent training phase lasting 2-4 weeks, an eligibility phase of up to 2 weeks 
to determine eligibility for the open-label phase, a 6-week open-label dose titration phase, a 2 week 
double-blind phase for Aptensio XR® responders, and a two-week follow-up call after study completion 
or early discontinuation to assess for ongoing adverse events and concomitant medications. 
Up to 150 subjects will be enrolled in this trial to allow for subjects who improve significantly during the 
behavior training phase and drop-outs.  Once 74 subjects have completed the double-blind phase, no 
additional subjects will be enrolled in the trial.  Subjects who are already enrolled at that time will be 
allowed to complete the trial. 
Phase 1: Screening 
The screening /washout period can last up to 4 weeks. 
Phase 2: Enrolment & Parent Training 
Eligible subjects will be enrolled in the study at Visit 2 and families will begin 4 parent training sessions.  
Sessions will last up to 90 minutes. The frequency of parent training sessions may be >4 days - <10 days 
apart. Families are expected to complete all 4 sessions of behavioural training within a 4 week period. 
With consultation from the medical monitor/coordinating PI’s, parents will be allowed to skip the 
behaviour management phase if the primary caregiver has participated in behaviour management therapy 
in the last 12 months with minimal benefit and/or the subject’s ADHD symptoms are severe enough to 
warrant moving immediately to the medication phase of the trial. 
Phase 3: Eligibility for Open Label Phase 
At Visit 6, eligibility to continue to the open-label phase will be determined.  Subjects who have less than

a 30% improvement on the ADHD-RS-IV and a Clinical Global Impression-Improvement (CGI-I) of 3 
(minimally improved or less) will undergo medical screening.   
Subjects who are eligible to continue to the open-label phase based on lack of improvement of ADHD 
symptoms and medical criteria will start open-label treatment.  Up to 2 weeks may elapse between Visits 
6 and 7 to allow for laboratory results to be obtained. However, the interval between visit 6 and 7 can be 
<2 weeks if the laboratory test and ECG results are available. 
Phase 4: Six-week Open-Label Phase 
Subjects will begin Aptensio XR® 10 mg at the morning following Visit 7.  At weekly visits (Visits 8-
13), dosing may be maintained or increased until an optimal dose or the maximum dose is reached.  The 
ADHD-RS-IV rating scale will be used to determine optimal dose. An optimal dose is a dose that 
produces a reduction of ADHD symptoms of at least 30% from Visit 7 with a CGI-I of “much improved” 
or “very much improved” with tolerable side effects.  Subjects who meet improvement criteria but may 
benefit from additional dose increases, may have their dose further optimized. If a higher dose is not 
tolerated, subjects may step down one dose level. 
Phase 5: Two-week Double-Blind Phase  
Subjects who have ≥30% response on the ADHD-RS-IV and a CGI of “much” or “very much improved” 
at the end of Visit 13 will enter the two-week parallel double-blind phase where they will be randomized 
to receive their best optimal dose of Aptensio XR® or placebo.   
Subjects who have a ≥50% worsening of symptoms on the ADHD-RS-IV from Visit 13 and a CGI-I of  6 
or 7 (much worse or very much worse) at Visit 14 will be eligible to discontinue the double-blind phase 
and enter the open-label extension study at investigator discretion after completing end of study (Visit 
15) procedures. 
 
At Visit 15, subjects will complete the double-blind phase and complete end of study procedures. 
Phase 6: Follow-up Phone Call 
 
A follow-up phone call will occur approximately two weeks after treatment discontinuation to 
assess for ongoing adverse events and concomitant medications. 
Proposed Statistical Analysis: 
The primary analysis will be an analysis of the change in ADHD-RS-IV Total Score during the double 
blind phase, comparing the change of subjects on placebo to the change of subjects on their optimal dose 
of Aptensio XR®. 
The primary efficacy population is the Evaluable population which includes all randomized subjects who 
were administered double-blind study medication, who completed ADHD-RS-IV assessments at the end 
of the open-label phase and at the end of the double-blind phase, and who did not have any major 
protocol violations.  The Intent to Treat population will include all randomized subjects who were 
administered any double-blind study medication. 
The primary efficacy measure will be the ADHD-RS-IV Total Score.  The primary analysis will be a 
two-way analysis of variance (terms for site and treatment) using each subjects’ change in ADHD-RS-IV

Total Score during the double-blind phase.  Treatment will have two values, Aptensio XR® and placebo. 
Statistical tests will be two-sided and p-values less than or equal to 0.05 will be considered statistically 
significant.    The primary efficacy analysis will use the Efficacy population, and the same analysis will 
be repeated with the ITT population. 
Secondary efficacy measures will be the ADHD-RS-IV hyperactivity/impulsivity and inattention 
subscale scores, CGI-S, CGI-I, and Conners EC BEH-P(S). Analysis of the ADHD-RS-IV subscale 
scores and the Conners EC BEH–P(S) score will be the same as for ADHD-RS-IV Total Score.  Analysis 
of the change in CGI-S from end of open label versus to end of double blind will be a Mantel-Haenszel 
test stratified on site.  Analysis of CGI-I at end of double blind phase (comparing end of double-blind to 
end of open-label) will be a Mantel Haenszel test stratified on site. 
All treatment-emergent adverse events will be summarized by number of subjects reporting. Separate 
analyses will be done for the open-label phase and for the double-blind phase.
