- Subjects where Study SPD503-318 was not available at the time of their final visit in the antecedent study (SPD503-315 or SPD503-316), may still be screened unless they are well-controlled on another ADHD medication with acceptable tolerability and the parent/caregiver is satisfied with their current ADHD medication.
- Subject satisfied all entry criteria for the antecedent study (SPD503 315 or SPD503-316).
- Subject who is a female of child-bearing potential (FOCP), defined as >9 years of age or <9 years of age and is post-menarchal, must have a negative serum beta human chorionic gonadotropin (hCG) pregnancy test at the Screening Visit (Visit 1) and a negative urine pregnancy test at the Baseline Visit (Visit 2) and agree to comply with any applicable contraceptive requirements of the protocol.
- Subject's parent or legally authorised representative (LAR) must provide signature of informed consent, and there must be documentation of assent (if applicable) by the subject indicating that the subject is aware of the investigational nature of the study and the required procedures and restrictions in accordance with the International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) Guideline E6 and applicable regulations, before completing any study-related procedures.
- Subject and parent/LAR are willing, able, and likely to fully comply with all the testing and requirements defined in this protocol, including oversight of dosing. Specifically, the parent/LAR must be available upon awakening, to dispense the dose of investigational product for the duration of the study.

- Subject is functioning at an age-appropriate level intellectually, as deemed by the Investigator.
- Subject is able to swallow intact tablets.
- Subject has any current, controlled (requiring a prohibited medication or behavioural modification program) or uncontrolled, co-morbid psychiatric diagnosis (except oppositional defiant disorder), including any severe comorbid Axis II disorders or severe Axis I disorders such as post traumatic stress disorder, bipolar illness, psychosis, pervasive developmental disorder, obsessive-compulsive disorder, substance abuse disorder, or other symptomatic manifestations or lifetime history of bipolar illness, psychosis or conduct disorder that, in the opinion of the Investigator, contraindicate treatment with SPD503 or confound efficacy or safety assessments. The Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime version (K-SADS-PL) rating from the antecedent study should be reviewed to confirm diagnosis, if necessary.
- Subject who early terminated from Study SPD503-315 or Study SPD503-316 for protocol non-adherence, subject non-compliance, an AE, SAE, or withdrawal by subject.
- Subject experienced any clinically significant AE in their prior SPD503 study (SPD503-315 or SPD503 316) that, in the opinion of the Investigator, would preclude exposure to SPD503.

Subjects with intermittent passive suicidal ideation are not necessarily excluded based on the assessment of the Investigator.

- Secondary Outcome Measures
Name Time Method Change From Baseline in Attention-deficit and Hyperactivity Disorder Rating Scale-IV (ADHD-RS-IV) - Total Score at Final Assessment Baseline (Day 0) and Final Assessment (last non missing data/up to Day 714) ADHD-RS-IV was developed to measure the behaviours of children with ADHD with 18 items. Each item is scored from a range of 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 (even numbered items 2-18) and inattentiveness (odd numbered items 1-17) with possible score range from 0 (no symptoms) to 27 (most severe symptoms). The ADHD-RS-IV possible total scores range from 0 (no symptoms) to 54 (most severe symptoms). Final Assessment is the last valid assessment obtained after Baseline (Visit 2/Day 0) whilst on investigational product and before first dose taper medication (Visit 19/ET/Day 714).
Number of Participants Assessed With Clinical Global Impression Severity of Illness (CGI-S) Scale Baseline (Day 0) and Final Assessment (last non missing data/up to Day 714) The CGI-S evaluate each participant's severity and improvement over time. The severity of a participant's condition is rated on a 7-point scale ranging from 1 to 7. The scale measures 0 = Not assessed, 1 = Normal, not at all ill, 2 = Borderline mentally ill (BL-MI), 3 = Mildly ill, 4 = Moderately ill, 5 = Markedly ill, 6 = Severely ill, 7 = Among the most extremely ill participant. Final Assessment is the last valid assessment obtained after Baseline (Visit 2/Day 0) whilst on investigational product and before first dose taper medication (Visit 19/ET/Day 714).
