You may qualify if…

1. Subject is 6 - 12 years old, inclusive at screening and randomization. 2. At least one of the subject's parents/legal guardians must give written informed consent, including privacy authorization, prior to study participation. The subject will provide informed assent prior to study participation.
Subject meets Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) criteria for a primary diagnosis of ADHD (inattentive, hyperactive, or combined presentation) at screening established by a comprehensive psychiatric evaluation that reviews DSM-5 criteria and confirmed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) at screening.
Subject is currently on a treatment regimen of a methylphenidate formulation within the approved labeled dose range for ADHD for at least 6 weeks prior to Day -7 with the same dose level for at least 1 week immediately prior to Day -7. Note: if any doses of methylphenidate were missed during the week prior to Day-7, the subject's eligibility will be discussed with the Medical Monitor.
In the opinion of the investigator, methylphenidate well tolerated and clinically effective based on clinical assessment and informant interview, as well as, review of available medical records. Note: The ADHD Rating Scale Version IV - Home Version (modified for investigator administration) (ADHD-RS-IV HV) will be administered at Screening by the investigator to inform clinical evaluation.
Subject is male or a non-pregnant, non-lactating female. 7. Subject, if female, must not be pregnant or breastfeeding, and if ≥ 8 years of age must have a negative serum pregnancy test at screening.
Female subjects of childbearing potential and male subjects with female partners of childbearing potential must practice true abstinence (consistent with lifestyle) and must agree to remain abstinent or agree to use an effective and medically acceptable form of birth control, from the time of informed consent/assent to at least 14 days after the last dose of the study drug has been taken.
Subject must be in general good health (defined as the absence of any clinically relevant abnormalities as determined by the investigator) based on screening physical and neurological examinations, medical history, and clinical laboratory values (hematology, chemistry, and urinalysis). Note: If any of the hematology, chemistry, or urinalysis results are not within the laboratory's reference range, then the subject can be included only if the investigator determines the deviations to be not clinically relevant.
Subject is within the 3rd to 97th percentile for gender specific body mass index (BMI)-for-age from the World Health Organization (WHO) growth charts and weighs at least 21 kg.
Subject must report a history of being able to swallow capsules. 12. Subject and subject's parent/legal guardian must be able to fully comprehend the informed consent/assent forms, understand and be willing and able to comply with all study procedures and visit schedule, and be able to communicate satisfactorily with the investigator and study coordinator.

You may not qualify if…

1. Subject or parent/legal guardian has commitments during the study that would interfere with attending study visits.
Subject, on Day 1, has not demonstrated evidence of worsening of ADHD symptoms as measured by ADHD-RS-IV HV total score ≥ 26 and at least a 30% worsening in ADHD-RS-IV HV total score since the last assessment and following a minimum 72-hour washout from prior methylphenidate treatment.
Subject is currently being treated for ADHD with an amphetamine-based product, or has been treated with an amphetamine-based product in the 6 weeks prior to the start of screening.
Subject is currently being treated for ADHD with a non-methylphenidate product, or has been treated with a non-methylphenidate product in the 6 weeks prior to the start of screening.
Subject has failed 2 adequate courses (dose and duration) of stimulant or non-stimulant treatment for ADHD, as judged by the investigator.
Subject currently has a diagnosis of asthma that has required daily treatment with bronchodilators or nebulizer treatments in the 30 days prior to screening and/or who may require daily treatments with these agents over the course of the trial. Intermittent use of bronchodilators is not exclusionary. Subjects who have a history of requiring persistent asthma treatment should be discussed with the medical monitor prior to randomization.
Subject has any clinically significant unstable medical abnormality, chronic disease, or a history of a clinically significant abnormality of the cardiovascular, gastrointestinal, respiratory, hepatic, or renal systems, or a disorder or history of a condition (eg, malabsorption, gastrointestinal surgery) that may interfere with drug absorption, distribution, metabolism, or excretion. Note: Active medical conditions that are minor or well-controlled are not exclusionary if they do not affect risk to the subject or the study results. In cases in which the impact of the condition upon risk to the subject or study results is unclear, the medical monitor should be consulted. Any subject with a known cardiovascular disease or condition (even if controlled) must be discussed with the medical monitor during screening.
Subject has a history or presence of abnormal ECGs, which in the investigator's opinion is clinically significant. Screening site ECGs will be centrally over-read, and eligibility will be determined by the investigator based on the results of the over-read report.
Subject has any diagnosis of bipolar I or II disorder, major depressive disorder, conduct disorder, obsessive-compulsive disorder, any history of psychosis, autism spectrum disorder, disruptive mood dysregulation disorder (DMDD), intellectual disability, Tourette's Syndrome, confirmed genetic disorder with cognitive and/or behavioral disturbances. Note: Subjects with oppositional defiant disorder (ODD) are permitted to enroll in the study as long as ODD is not the primary focus of treatment.
Subject has generalized anxiety disorder or panic disorder that has been the primary focus of treatment at any time during the 12 months prior to screening or that has required pharmacotherapy any time during the 6 months prior to screening.
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 (eg, Duchenne Muscular dystrophy, myasthenia gravis, or other neurologic or serious neuromuscular disorders), or history of persistent neurological symptoms attributable to serious head injury. Past history of febrile seizure, drug-induced seizure, or alcohol withdrawal seizure is exclusionary. Subject taking anticonvulsants for seizure control currently or within the past 2 years is not eligible for study participation.
Subject has uncontrolled thyroid disorder as evidenced by thyroid stimulating hormone (TSH) ≤ 0.8 x the lower limit of normal (LLN) or ≥ 1.25 x the upper limit of normal (ULN) for the reference laboratory.
Subject answers "yes" to "Suicidal Ideation" item 4 (active suicidal ideation with some intent to act, without specific plan) or item 5 (active suicidal ideation with specific plan and intent) for any lifetime history on the C-SSRS Children's Lifetime/Recent assessment at screening.
Subject has any history of attempted suicide or clinically significant suicidal ideation, in the opinion of the investigator.
