- Subject has a concurrent chronic or acute illness (such as severe allergic rhinitis or an infectious process requiring antibiotics), disability, or other condition that might confound the results of safety assessments conducted in the study or that might increase risk to the subject. Similarly, the subject will be excluded if he or she has any additional condition(s) that, in the investigator's opinion, would prohibit the subject from completing the study or would not be in the best interest of the subject. The additional conditions would include any significant illness or unstable medical condition that could lead to difficulty complying with the protocol. Mild, stable asthma is not exclusionary.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Treatment-emergent Adverse Events (TEAEs) at the Specified Dose Level
Time Frame: From start of study treatment up to safety follow-up (Week 9)
|
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
An AE was considered treatment-emergent if it had a start date on or after, or had a start date before but increased in severity after the first dose of investigational product.

From start of study treatment up to safety follow-up (Week 9)

Change in Sleep Patterns Assessed by Children's Sleep Habits Questionnaire at Week 8 / End of Treatment (ET)
Time Frame: Baseline, Week 8/ET
|
Children's Sleep Habits Questionnaire is a tool designed to screen the most common sleep problems in children, and consists of 33 items for scoring.
The instrument evaluates the child's sleep based on behavior within 8 different subscales: bedtime resistance, sleep-onset delay, sleep duration, sleep anxiety, night walkings, parasomnias, sleep-disordered breathing, and daytime sleepiness.
Each item receives a score from 1 (problem occurs rarely) to 3 (problem usually occurs); therefore, a higher score is the worse outcome.
Scale ranges are as follows: bedtime resistance: 6 to 18, sleep onset delay: 1 to 3, sleep duration: 3 to 9, sleep anxiety: 4 to 12, night walkings: 3 to 9, parasomnias: 7 to 21, sleep-disordered breathing: 3 to 9, daytime sleepiness: 8 to 24, and total disturbance (items from all scales): 33 to 99.
|
Baseline, Week 8/ET
|
Number of Participants With Suicide Related Behavior Assessed by Columbia-Suicide Severity Rating Scale Questionnaire (C-SSRS)
Time Frame: Baseline, Week 8/ET
|
The C-SSRS is a semi-structured interview that captures the occurrence, severity, and frequency of suicide-related thoughts and behaviors.
The interview includes definitions and suggested questions to solicit the type of information needed to determine if a suicide-related thought or behaviour occurred.
The interview was initiated with 5 (yes/no) questions, presented in ascending order of severity, about suicidal ideation.
The most severe type of ideation was rated for frequency, duration, controllability, deterrents, and reason.
If the answer to the first 2 ideation questions was "yes," the clinician asked questions 3-5.
Active suicidal ideation included any participant who answered "yes" to questions 2-5.
If the answers to ideation questions 1 and 2 were "No," then the clinician proceeded to 5 (yes/no) questions that addressed suicidal behavior, which was categorized as actual attempt, interrupted attempt, aborted attempt, preparatory acts or behaviors, and completed suicide.

Change From Baseline in Attention Deficit/Hyperactivity Disorder Rating Scale (ADHD-RS-IV) Preschool Version Total Score at FoTA (Final on Treatment Assessment)
Time Frame: Baseline, FoTA
|
The ADHD-RS-IV Preschool Version is an 18-item questionnaire that requires the respondent to rate the frequency of occurrence of ADHD symptoms as defined by Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-IV-TR) criteria.
Each item is scored on a 4-point scale ranging from 0 (never or rarely) to 3 (very often) with total scores ranging from 0-54.
The 18 items may be grouped into 2 subscales: hyperactivity/impulsivity (even numbered items 2-18) and inattentiveness (odd numbered items 1-17).
Data presented here was analysed at Final on-Treatment Assessment (FoTA).
|
Baseline, FoTA
|
Number of Participants With Improvement on Clinical Global Impression-Improvement (CGI-I)
Time Frame: FoTA
|
CGI-I was performed to rate the severity of a participant's condition on a 7-point scale (1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; or 7=very much worse).
Data presented here was analysed at Final on-Treatment Assessment (FoTA).
Improved is defined as a score of "very much improved" or "much improved".

Area Under the Concentration-Time Curve From Time Zero to Time of the Last Quantifiable Concentration (AUC 0-last) of SPD489 in Plasma
Time Frame: Visit 7 [Dose Maintenance Phase] at pre-dose, and 1, 2, 3, 4, 6, and 8 h post-dose
|
AUC 0-last is the area under the concentration-time curve from time zero to the time of the last quantifiable concentration of SPD489 in plasma.
Pharmacokinetic (PK) parameters were compared against the study NRP104-201 (NCT00557011) to observe and compare the effects of SPD489.
