• Subject has a history of epilepsy, seizures (except childhood febrile seizures), unexplained syncope or other unexplained blackouts (except single incident), or head trauma with loss of consciousness lasting more than 5 minutes.
• Subject has a currently active medical condition (other than ADHD) that, in the opinion of the investigator, could interfere with the ability of the subject to participate in the study.
• Subject is currently taking an antidepressant medication (eg, bupropion, selective serotonin reuptake inhibitor [SSRI]/ serotonin norepinephrine reuptake inhibitor [SNRI], monoamine oxidase [MAO] blocker, tricyclic, etc) or St. John's Wort.
• Subject is currently taking or has taken within the previous 6 months an anticonvulsant medication (eg, phenytoin, carbamazepine, lamotrigine, valproic acid, etc); antipsychotic medication; or lithium (any lithium preparation or formulation).
• Subject is currently taking an alpha-2 adrenergic receptor agonist (including clonidine and guanfacine).
• Subject has a Body Mass Index (BMI) less than 18 or greater than 35 kg/m2 (refer to Appendix V)
• 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) on the C-SSRS assessment at screening (in the past month). Subjects who answer "yes" to this question must be referred to the Investigator for follow-up evaluation.
• Subject has attempted suicide within 2 years prior to the screening period.
• Subject has history of positive test for Hepatitis B surface antigen or Hepatitis C antibody. Note: Subjects with a history of a positive test for Hepatitis B surface antigen or Hepatitis C antibody may be enrolled in the study if they have liver function test results at screening within the normal range.

• Subject has a clinically significant abnormality on screening evaluation including physical examination, vital signs, ECG, or laboratory tests that the investigator in consultation with the medical monitor considers to be inappropriate to allow participation in the study.

• The subject's screening hematology results show an alanine aminotransferase (ALT) or aspartate aminotransferase (AST) value ≥ 2 times the upper limit of normal (ULN), or a blood urea nitrogen (BUN) value ≥ 1.5 times the ULN for the reference lab.
• Subject who is currently participating or has participated in a clinical trial within the last 180 days or who participated in more than 2 clinical trials within the past year. This includes studies using marketed compounds or devices.
