Outcome Measures
Primary Outcomes (1)
Lean Squares Mean (± Standard Error) of Math Test Score Over All Post-dose Time Points (0.5, 1, 2, 4, 8, 10, 12, 13, and 14 Hours Post-dose) Assessed During the Administration of Serial Math Tests at Visit 5 (Week 5)
The Total Math Score is the sum of the number of math problems attempted plus the number of math problems answered correctly and it provides an objective measure of performance that is time-sensitive, ADHD medication-sensitive, and well documented as a measure to evaluate ADHD medication effectiveness throughout the day. The Total Math Score ranges from 0-800 with higher scores indicating better performance.
Pre-dose to 14 hour post-dose
