Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This is a multicenter, dose-optimized, randomized, double-blind, placebo controlled, efficacy and safety study with Azstarys® in children 4 to 12 years of age with attention-deficit/hyperactivity disorder (ADHD). Azstarys® contains dexmethylphenidate (d-MPH) and serdexmethylphenidate (SDX), a prodrug of d-MPH and is orally administered. The primary objective is to determine the efficacy of Azstarys® compared to placebo in treating children ages 4 to 12 years old with ADHD. The study will consist of two randomized and blinded treatment cohorts ages 4 to 5 years of age and 6 to 12 years of age. Randomization will be applied separately with a starting dose up-titration at different dose levels for each cohort. 130 and 100 subjects will be enrolled, respectively. Approximately 20 sites will participate.

2. Subjects must have a body weight within the 5th and 95th percentile according to the gender-specific weight-for-age percentile charts from the Centers for Disease Control and Prevention (CDC). See calculator at https://www.infantchart.com/child/.
3. Female subjects must agree, if they are of childbearing potential at Screening or when they become of childbearing potential during the study, to remain abstinent or agree to use an effective and medically acceptable form of birth control from the time of written or verbal assent to at least 14 days after the last dose of study drug. Childbearing potential is defined as follows: Girls under the age of 12 who have not had their first period will be considered "not of child-bearing potential." Girls 12 years of age (including girls who will become 13 years during the study) will be considered "of child-bearing potential," even if they have not yet had their first period.

4. Subjects must be in general good health defined as the absence of any clinically relevant abnormalities as determined by the Investigator based on physical examinations, vital signs, electrocardiograms (ECGs), medical history, and clinical laboratory values (chemistry, hematology, urinalysis) at Screening. If any of the chemistry or hematology tests 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.
5. At least one parent/legal guardian of the subject must voluntarily give written permission for him/her to participate in the study.

3. 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.

7. Subject has a current (last month) psychiatric diagnosis other than specific phobia, motor skills disorders, ODD, sleep disorders, elimination disorders, adjustment disorders, learning disorders, or communication disorders. Subjects allowed to enroll with any of these DSM disorders will require written justification from the Investigator documenting why the conditions will not interfere with participation and to emphasize that ADHD is the primary indication.

17. Subject has taken ADHD medications from more than one class within 30 days prior to Screening. Subjects on a stable dose of one ADHD medication with occasional use of ADHD medications from another class are eligible at the discretion of the Investigator.
