A higher TDQ score reflects better driving skill. A TDQ of 100 represents average driving and the standard deviation of normal distribution is 15. The normal range of driving (+/- 1.0 SD) is 85 to 115.

Each subject will be randomized to receive up to a 21-day course of PRC-063 followed by up to a 21 day course of LDX or vice versa. There will be no washout between treatments. On days 1 through 7, subjects will receive the lowest dose (45 mg of PRC-063 or 30 mg of LDX) of study medication. On days 8 through 14, subjects will receive the middle dose (70 mg of PRC-063 or 50 mg of LDX). On days 15 through 21, subjects will receive the highest dose (100 mg of PRC-063 or 70 mg of LDX). During Days 1 through 21, if a subject is responding satisfactorily to medication, he or she may remain on that daily dose. Driving laboratory testing will be conducted between Day 17 and Day 21. Following the laboratory testing, the subject will begin a second titration of the alternate treatment, starting on Day 22 through Day 28 at the lowest dose (45 mg of PRC-063 or 30 mg of LDX) of study medication, Day 29 through Day 35 on the middle dose (70 mg of PRC-063 or 50 mg of LDX) and Day 36 through Day 42 on the highest dose (100 mg of PRC-063 or 70 mg of LDX). During Days 22 through 42, if a subject is responding satisfactorily to medication, he or she may remain on that daily dose. Following titration with the second treatment, subjects will attend a second driving laboratory testing, conducted between Day 38 to Day 42. Subjects will subsequently attend a safety and study termination visit.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '35 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\nMale or non-pregnant, non-nursing female at least 18 years of age and less than or equal to 25 years of age with a valid driver's license and at least six months of driving experience with driving activity at least twice per week.\n\nADHD diagnosis, inattentive, hyperactive/impulsive or combined, as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) based on clinician assessment using the Structured Clinical Interview for DSM Disorders (SCID).\n\nDissatisfaction with his or her current pharmacological therapy for treatment of ADHD or not currently receiving pharmacological therapy for ADHD.
