Subject and a parent/legal guardian must plan to be available for the entire study period.
11. Female subjects of childbearing potential (i.e., post-menarche) are required to have a negative result on urine pregnancy testing at screening (and will be given specific instructions for avoiding pregnancy during the study).

Exclusion Criteria:

1. History of, or current, medical condition or laboratory result which, in the opinion of the investigator, unfavorably alters the risk-benefit of study participation, may jeopardize subject safety, or may interfere with the satisfactory completion of the study and study-related procedures.
2. Serious structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, or other cardiac problems that may place the subject at increased vulnerability to the sympathomimetic effects of a stimulant drug.
3. History of seizure disorder (except febrile seizures prior to age 5 and at least 1 year prior to study participation), Tourette's disorder, or intellectual disability of minor severity or greater (DSM5 criteria).

Medications not covered in allowed medications or prohibited medications (Section 8.1.1) must be cleared by the medical monitor prior to enrolling the subject.
11. Participation in a clinical study with an investigational drug within the 30 days preceding study enrollment.
12. Previous treatment experience with HLD200.
13. Positive screening for illicit drug use or nicotine and/or current health conditions or use of medications that might confound the results of the study or increase risk to the subject.
14. In the opinion of the investigator, the subject may have problems complying with the protocol or the procedures of the protocol, or could face unnecessary safety risks from the study. This includes current health conditions or use of medications that might confound the results of the study or increase risk to the subject.
15. Subject's systolic or diastolic blood pressure measurement exceeds the 95th percentile for age, sex, and height at the Baseline visit.
16. Subject is significantly underweight based on Centers for Disease Control and Prevention body mass index (BMI)-for-age sex-specific values at the Screening Visit. Significantly underweight is defined as a BMI \<5th percentile.
17. Subject is significantly overweight based on Centers for Disease Control and Prevention BMI-for-age sex specific values at the Screening Visit. Significantly overweight is defined as a BMI \>95th percentile.
