Assess the Safety and Pharmacokinetics of Ascending, Multiple Oral Doses of SPD489 in Adults With Schizophrenia

Blood pressure and pulse measurements were taken using an automated blood pressure monitoring device (ideally using the same device, the same arm and in the same position throughout the study). Measurements of vital signs were performed in triplicate (3 measurements) after the subject had been in a sitting position for at least 5 minutes. Each of the 3 triplicate readings were performed in succession, at least 1-2 minutes apart, with the cuff fully deflated between measurements. It was expected that the triplicate measurements be obtained within a 5-6 minute period.

BAS scale has objective, subjective, and global impression components of akathisia (motor restlessness that manifests itself with an inability to sit still or remain motionless). Objective and subjective components are rated on a scale from 0 (normal/absence) to 3 (severe) and are summed yielding a total score of 0 to 9. Global impression is rated on a scale from 0 (absent) to 5 (severe) with a total score ranging from 0 to 5. Lower scores indicate reduced restlessness.

This battery is a series of 4 computerized cognition tests (Groton Maze Learning Test, Detection Task, Identification Task, and One Card Learning Task) designed to measure reaction time, visual learning and reasoning, and problem solving. The entire battery takes approximately 12 minutes to complete. CogState scores are measured on a linear scale (no maximum score). The Groton Maze Learning Test measures total number of errors made in problem solving (lower score = better performance). The Detection Task is measured by speed of performance (lower score = better performance). The Identification Task is measured by speed of performance (lower score = better performance). One Card Learning Task measures the accuracy of performance (higher score = better performance).

The entire battery takes approximately 12 minutes to complete. CogState scores are measured on a linear scale (no maximum score). The Groton Maze Learning Test measures total number of errors made in problem solving (lower score = better performance). The Detection Task is measured by speed of performance (lower score = better performance). The Identification Task is measured by speed of performance (lower score = better performance). One Card Learning Task measures the accuracy of performance (higher score = better performance).
