• Female subjects of childbearing potential and male subjects with female partners of childbearing potential must agree to use an effective and medically acceptable form of birth control throughout the study period.

• Subject has a negative breath alcohol test and a negative urine drug screen (UDS) for any illicit drug at screening.

• Subject is judged by the investigator to be suitable for participation in a 12 month clinical trial involving open-label dasotraline treatment.

• Subject can read well enough to understand the informed consent form and other subject materials.

Exclusion Criteria:

• Subject has a psychiatric disorder other than ADHD that has been the primary focus of treatment at any time during the 12 months prior to screening.
