Primaire uitkomstmaten

Maatregel Beschrijving
Tijdsspanne
Swanson, Kotin, Agler, M-Flynn, and Pelham Rating Scale (SKAMP)-Combined Scores-Average of All Post-Dose Time-Points
Tijdsspanne: 0.75 up to 13 hours post-dose
The SKAMP scale measured the manifestations of attention deficit hyperactivity disorder (ADHD) using an independent observer rating of the participant's impairment in classroom observed behaviors. SKAMP combined score comprised of 13 items (including subscales: attention with items 1-4, deportment with items 5-8, quality of work with items 9-11 and compliance with items 12-13). The SKAMP composite score was obtained by summing up each item score where each item was rated on a 7-point impairment scale (0=normal to 6=maximal impairment) for a total possible combined score of 0 to 78; where higher score signified worst impairment. Average of all post dose SKAMP-combined scores measured at 0.75, 2, 4, 8, 10, 12 and 13 hours post-dose was calculated.
0.75 up to 13 hours post-dose

Tijdsspanne
Onset and Duration of Clinical Effect
Tijdsspanne: 0.75, 2, 4, 8, 10, 12, 13 hours post-dose
Onset and duration of clinical effect was determined using SKAMP combined rating scale at each post-dose time point. Onset of effect was defined as first assessment time showing statistical significance (i.e. p was less than or equal to [=<] 0.05) between NWP09 and placebo and duration of effect was defined as the as last consecutive time-point at which difference was statistically significant between NWP09 and placebo. SKAMP scale measured the manifestations of ADHD using an independent observer rating of the participant's impairment in classroom observed behaviors. SKAMP combined score was comprised of 13 items [subscales: attention (1-4 items), deportment (5-8 items), quality of work (9-11 items) and compliance (12-13 items)]. SKAMP combined score was obtained by summing up each item score where each item was rated on a 7-point impairment scale (0=normal to 6=maximal impairment) for total possible combined score of 0 to 78; where higher score signified worst impairment.

Swanson, Kotin, Agler, M-Flynn, and Pelham Rating Scale (SKAMP) SKAMP Attention and Deportment Subscale Scores at Hour 0.75, 2, 4, 8, 10, 12 and 13 Post-Dose
Tijdsspanne: 0.75, 2, 4, 8, 10, 12, 13 hours post-dose
SKAMP scale measured the manifestations of ADHD using an independent observer rating of the participant's impairment in classroom observed behaviors. The SKAMP subscales were obtained by summing the individual items as follows: Attention (items 1-4) and Deportment (items 5-8), where each item was rated on a 7-point scale (0=normal to 6=maximal impairment). SKAMP attention subscale was reported which evaluates concentration in the classroom and comprises of 4 items, with a total possible score for of 0 to 24; higher score indicates worst impairment. SKAMP deportment subscale was reported which assesses behavior in the classroom and comprises of 4 items, with a total possible score for each sub-scale of 0 to 24; higher score indicates worst impairment.
0.75, 2, 4, 8, 10, 12, 13 hours post-dose
Permanent Product Measure of Performance (PERMP) Scores at Hour 0.75, 2, 4, 8, 10, 12 and 13 Post-Dose
Tijdsspanne: 0.75, 2, 4, 8, 10, 12 and 13 post-dose
The PERMP score measured the manifestations of attention deficit hyperactivity disorder. The PERMP is a 10-minute written test, on 80 math problems, performed as seatwork in the classroom. At the end of the 10- minute math test , the PERMP score of the number of math problems attempted plus the number of math problems answered correctly in a 10-minute session was used to measure participant's performance. The total score range from 0-160 with higher scores indicating better performance.
0.75, 2, 4, 8, 10, 12 and 13 post-dose

Tijdsspanne
Clinical Global Impression of Severity (CGI-S)
Tijdsspanne: Baseline, Day 8, 15, 22, 29, 36, 43
CGI-S scale was used to measure features associated with ADHD. The assessment was performed by the investigator of the study research team. The CGI-S classified the participant's current disease status as: 1 = normal, not at all ill, 2 = borderline ill, 3 = mildly ill, 4 = moderately ill, 5 = markedly ill, 6 = severely ill, and 7 = among the most extremely ill participants. This outcome measure was analyzed during open label phase in entire study population prior to randomization into two treatment groups.
Baseline, Day 8, 15, 22, 29, 36, 43
Clinical Global Impression-Improvement (CGI-I)
Tijdsspanne: Day 8, 15, 22, 29, 36, 43
The CGI-I measured the participant's disease improvement relative to baseline as followed: 1= very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6= much worse, and 7=very much worse. This outcome measure was analyzed during open label phase in entire study population prior to randomization into two treatment groups.
Day 8, 15, 22, 29, 36, 43
Conners Parent Rating Scale (CPRS) Scores
Tijdsspanne: Baseline, Day 8, 15, 22, 29, 36, 43
CPRS was used to measure features associated with ADHD and was used to compare scores during the dose optimization period i.e. 1-6 weeks. The assessment was performed by parent or guardian. CPRS consisted of 27 questions graded on a scale from 0 (not true at all) to 3 (very much true). Raw scores were converted to t-scores and t-scores have a mean of 50 ± 10 where higher scores are indicative of greater problems. The participant received normalized t-scores on the following scales: oppositional, cognitive problems/inattention, hyperactivity, anxious-shy, perfectionism, social problems, psychosomatic, ADHD index, restless-impulse, emotional liability, conner's global index, inattentive, hyperactive-impulsive and diagnostic and statistical manual of mental disorders IV (DSM-IV). This outcome measure was analyzed during open label phase in entire study population prior to randomization into two treatment groups.
