A Phase 2, Open-label, Multicenter, Exploratory Safety, Tolerability, Pharmacokinetic, and Efficacy Study of SPD489 in Preschool Children Aged 4-5 Years With Attention-deficit/Hyperactivity Disorder

The purpose of this study is to gain initial safety, tolerability, pharmacokinetic, and
efficacy information on SPD489 in preschool children 4-5 years old who are diagnosed with
ADHD. Generating such data will provide data on the use of SPD489 in the preschool ADHD
population.


Inclusion Criteria:

1. Subject is a male or female aged 4-5 years inclusive at the time of consent. Only

of ≥24.

6. Subject has a CGI-S score ≥4 at the Baseline Visit (Visit 0).

7. Subject has a Peabody Picture Vocabulary Test, Fourth Edition standard score of ≥70 at
the Screening Visit (Visit -1).

8. Subject has undergone an adequate course of non-pharmacological treatment based on
investigator judgment or the subject has a severe enough condition to consider
enrollment without undergoing prior non-pharmacological treatment based on
investigator judgment.

9. Subject has, in the opinion of the investigator, participated in a structured group
activity (e.g., preschool, sports, Sunday school) so as to assess symptoms and
impairment in a setting outside the home.

10. Subject has lived with the same parent/LAR for ≥6 months.

Exclusion Criteria:

tolerability.

4. Subject has a concurrent chronic or acute illness (such as severe allergic rhinitis or
an infectious process requiring antibiotics), disability, or other condition that
might confound the results of safety assessments conducted in the study or that might
increase risk to the subject. Similarly, the subject will be excluded if he or she has
any additional condition(s) that, in the investigator's opinion, would prohibit the
subject from completing the study or would not be in the best interest of the subject.
The additional conditions would include any significant illness or unstable medical
condition that could lead to difficulty complying with the protocol. Mild, stable
