Arms Assigned Interventions
Active Comparator: A: SPD503 (4mg) Drug: SPD503
SPD503 extended-release 4mg orally administered tablets. There are 3 dosing periods in the study. Subjects will receive one dosing regimen (arm) as a single oral dose on the first day of each dosing period. The order in which the subjects receive each arm (regimen) is randomly assigned. There is a 7-day break between each dosing period in which no medication is taken.
Other Name: guanfacine hydrochloride
Active Comparator: B: VYVANSE (50mg) Drug: VYVANSE
VYVANSE 50mg orally administered capsules. There are 3 dosing periods in the study. Subjects will receive one dosing regimen (arm) as a single oral dose on the first day of each dosing period. The order in which the subjects receive each arm (regimen) is randomly assigned. There is a 7-day break between each dosing period in which no medication is taken.
Other Name: lisdexamfatamine dimesylate (LDX)
Active Comparator: C: SPD503 (4mg) + VYVANSE (50mg) Drug: SPD503 and VYVANSE
SPD503 4mg tablets + VYVANSE 50mg capsules orally administered together. There are 3 dosing periods in the study. Subjects will receive one dosing regimen (arm) as a single oral dose on the first day of each dosing period. The order in which the subjects receive each arm (regimen) is randomly assigned. There is a 7-day break between each dosing period in which no medication is taken.
