• Subject has an intelligence quotient (IQ) > 79, based on the Wechsler Abbreviated Scale of Intelligence, second edition (WASI-II).
• Subject has been genotyped previously and determined to have disruptive mutations in genes within the glutamate receptor metabotropic (GRM)-network as determined by the presence of copy number variations (CNVs) (GRM biomarker-positive subjects). The confirmation of a subject's positive status will be provided by the sponsor.
• Subject is judged to be in general good health, other than having ADHD, based on medical history, physical examination, vital signs measurements, laboratory safety tests, and the Columbia Suicide Severity Rating Scale (C-SSRS) performed at the Screening Visit and/or prior to administration of investigational product (IP).
• Subject has no clinically significant abnormality on electrocardiogram (ECG) performed at the Screening Visit and/or prior to administration of IP such as serious arrhythmia, bradycardia, tachycardia, cardiac conduction problems, or other abnormalities deemed to be a potential safety issue.
• Parent/legal guardian and subject understand the study procedures and agree to the subject's participation in the study as indicated by parental/legal guardian signature on the subject informed consent form and subject signature on the assent form.

Exclusion Criteria:

• Subjects with prior diagnosis of comorbid major psychiatric disorders (ie, aside from ADHD), including major depression, bipolar disease, schizophrenia, pervasive development disorder, and intellectual disability.
• Subject is currently taking a prohibited medication and/or is unwilling to wean off current ADHD medication to participate in the study
• Subject has a history of any illness that in the opinion of the study investigator might confound the results of the study or poses an additional risk to the subject by his or her participation in the study.
• Subject has a known history or presence of syncope, cardiac conduction problems (eg, clinically significant heart block), exercise-related cardiac events including syncope and pre-syncope, or clinically significant bradycardia.
• Subject has a history of stroke, chronic seizures, or major neurological disorder which, in the opinion of the investigator, would interfere with the subject's ability to participate and/or be evaluated in the study.
