Inclusion criteria
. Male or female subjects between 6 and 17 years of age (inclusive) at the time of Randomization (Visit 2). Subjects who are expected to turn 18 years of age during the trial will not be allowed.
. Subject must have a body weight between the 5th and 95th percentile (≥5th percentile and ≤95th percentile) for their respective age and sex.
. Subject is unsatisfied with his/her current pharmacological therapy for treatment of ADHD or not currently receiving pharmacological therapy for ADHD. Inclusion of subjects who are naïve to pharmacological therapy for ADHD is permitted.
. Subjects of child-bearing potential at screening or that become of child-bearing potential during the study must agree to remain abstinent or agree to use a highly effective, medically acceptable form of birth control for the time of written assent and for at least 30 days after the last dose of study drug has been taken (females). Male subjects with female partners must agree at Screening to remain abstinent or agree to use an effective and medically acceptable form of birth control from Screening to 90 days after the last dose of study drug. Child-bearing potential is defined as any female who has had their first period or is 12 years or older (or will be 12 while in the study).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
The Primary Efficacy Analysis Will Analyze the Mean Change From Baseline (Pre-dose) at Visit 2 of Attention Deficit Hyperactivity Disorder Rating Scale 5 (ADHD-RS-5) Scores to ADHD-RS-5 at Visit 8.
. Subject must be in general good health defined as absence of any clinically relevant abnormalities as determined by the Investigator based on physical and neurological examinations, vital signs, ECGs (QTc less than or equal to 460 milliseconds), medical history, and laboratory values (hematology, chemistry, serology, TSH, or urinalysis) at Screening. If any of the exams or values are not within the laboratory reference range, the Investigator must review range and determine if clinically relevant. If clinically relevant, the subject is not eligible for the study.
. Subject's intellectual function is at an age-appropriate level, as deemed by the Investigator.
. Subject must meet Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) criteria for the primary diagnosis of ADHD or any of the three presentations (combined, inattentive, or hyperactive/impulsive presentation) upon clinical evaluation and confirmed by the MINI International Neuropsychiatric Interview of Children and Adolescents (MINI-KID). The MINI should also be used to evaluate any other psychotic disorders.
. Subject must score 28 or higher on the ADHD-RS-5 scale at the Baseline visit (Visit 2).
Exclusion criteria
. If female and of child-bearing potential, the subject must not be pregnant or breastfeeding at any time during the study or for 30 days following the completion of the study, defined as completion of safety visit at the end of study (Visit 9). If of child-bearing potential, urine hCG tests will be administered at protocol-specified time points. Any positive pregnancy test during the study will exclude them from further participation in the study.
. Subject has any psychiatric diagnosis of bipolar I or II disorder, major depressive disorder, conduct disorder, disruptive mood dysregulation disorder (DMDD), intellectual disability, obsessive-compulsive disorder, eating disorder, anxiety disorder (including generalized anxiety disorder), any history of psychosis, autism spectrum disorder, a history of motor or vocal tics or Tourette's Syndrome, confirmed genetic disorder with cognitive and/or behavioral disturbances, or any other diagnosis/significant medical history that at the discretion of the Investigator excludes the subject from entry into the study.
. Subject has evidence of any chronic disease of the central nervous system (CNS) such as tumors, inflammation, seizure disorder, vascular disorder, potential CNS-related disorders that might occur in childhood, or history of persistent neurological symptoms related to a serious head injury.
. Subject has any clinically significant and/or unstable/uncontrolled medical abnormality or chronic medical condition, persistent neurological symptoms, history of cardiovascular abnormality, abnormalities of respiratory, hepatic, gastrointestinal, renal, or any disorder or history of a condition that would impact or interfere with drug absorption, distribution, metabolism, or excretion during the study or may interfere with the participants ability to participate in the study.
. Subject has family history of early cardiovascular disease or sudden death.
. Subject has any history of attempted suicide or clinically significant suicidal ideation based on the Columbia Suicide Severity Rating Scale (C-SSRS) assessment, or answers "yes" to "Suicidal Ideation" item 4 or 5 of any lifetime history on the C-SSRS Children's Lifetime/Recent assessment at screening.
. Subject has history of seizures, excluding febrile seizures.
. Subject has a known primary sleep disorder (e.g., sleep apnea, narcolepsy, etc.)
