Primary Outcome Measures:
  • Maintenance of Wakefulness Test (MWT) [ Time Frame: Over a period of 8 hours ] [ Designated as safety issue: No ]
    The MWT was conducted to determine the subjects' ability to stay awake. Subjects sat in a darkened room and were told to "stay awake as long as possible" during the 30 minute session. This is an indicator of how well you are able to function and remain alert in quiet times of inactivity. Higher times are better.


Secondary Outcome Measures:
  • Karolinska Sleepiness Scale (KSS) Scores [ Time Frame: Over a period of 15 hours ] [ Designated as safety issue: No ]
    The KSS is a 9-point scale on which the subject rates sleepiness from 1 (very alert) to 9 (very sleepy/fighting sleep). Lower score is better.

  • KSS Scores by Timepoint [ Time Frame: Over a period of 15 hours ] [ Designated as safety issue: No ]
    The KSS is a 9-point scale on which the subject rates sleepiness from 1 (very alert) to 9 (very sleepy/fighting sleep). Lower score is better.

  • Psychomotor Vigilance Task (PVT) Scores [ Time Frame: Over a period of 12 hours ] [ Designated as safety issue: No ]
    PVT assesses behavioral alertness. Subjects were required to respond to a visual stimulus by pressing a button on a mechanical device and the reaction time was measured. Higher scores indicate attention lapses.

  • PVT Scores by Timepoint [ Time Frame: Over a period of 12 hours ] [ Designated as safety issue: No ]
    PVT assesses behavioral alertness. Subjects were required to respond to a visual stimulus by pressing a button on a mechanical device and the reaction time was measured. Higher scores indicate attention lapses.

  Eligibility

Ages Eligible for Study:   18 Years to 40 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Male subjects between the ages of 18-40 years.
  • The subject is in good health and must have a satisfactory medical assessment with no clinically significant and relevant abnormalities (of medical history, physical examination, electrocardiogram (ECG), clinical laboratory evaluation (hematology, biochemistry, and urinalysis).
  • Subject has a history of regular sleep-wake habits, routinely spending 6.5-8 hours in bed nightly, and does not oversleep by more than 3 hours on weekends.
  • Subject has the ability to provide written, signed, and dated (personally) informed consent to participate in the study, in accordance with the International Conference on Harmonisation Good Clinical Practice Guideline E6 and applicable regulations, before completing any study-related procedures.

Exclusion Criteria:

  • Current or relevant previous history of serious, severe, or unstable (acute or progressive) physical or psychiatric illness, any medical disorder that may require treatment or make this subject unlikely to fully complete the study, or any condition that presents undue risk from SPD489 or armodafinil or procedures. Comorbid psychiatric diagnosis will be established by a psychiatric evaluation that includes the Mini International Neuropsychiatric Interview (MINI)-Plus.
  • Subject is currently considered a suicide risk, has previously made a suicide attempt, or has a prior history of, or is currently demonstrating suicidal ideation.
  • Subject has a known or suspected sleep disorder, or another disorder associated with excessive daytime sleepiness, or any other diagnosis that would interfere with assessing sleepiness in subjects with study related induced sleepiness or abnormal findings on the initial PSG conducted on Day -1 such as, but not limited to, Apnea-Hypopnea Index (AHI) or Periodic Limb Movement Arousal Index (PLMAI) >10.
