Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 12 years (Child)

Description

Inclusion Criteria:

  • Male or female from 6 to 12 years of age at the time of screening, inclusive.
  • Diagnosis of ADHD by a Psychiatrist, Psychologist, Developmental Pediatrician, or a Pediatrician meeting diagnostic criteria for ADHD (DSM-IV). A Schedule for Affective Disorders and Schizophrenia for School Age Children (K-SADS)16 was administered on all subjects to assist in diagnostic process.
  • A clinician-administered Clinical Global Impression of Severity (CGI-S) score of 3 or greater. An Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS) score at screening or baseline greater than or equal to the 90th percentile normative values for gender and age in at least one of the following categories: the hyperactive-impulsive subscale, inattentive subscale or the total score.
  • Subject must have been in need of pharmacological treatment for ADHD.
  • Subjects taking a medication to control ADHD at the time of screening must have been experiencing suboptimal efficacy, a safety or tolerability issue or in need of a long-acting liquid formulation.
  • For subjects taking any daily medication at screening aside from ADHD medication: parent or legal guardian agreed that there would be no elective changes in subject's medications during the study (10 weeks total).

Exclusion Criteria:

  • Excluded comorbid psychiatric diagnoses: DSM-IV Axis I diagnosis (active) other than ADHD, with the exception of Specific Phobias, Learning Disorders, Motor Skills Disorders, Communication Disorders, Oppositional Defiant Disorder, Elimination Disorders, Sleep Disorders, and Adjustment Disorders.
  • Clinically significant cognitive impairment as assessed in the clinical judgment of the Investigator. In cases where this was not clear, study staff were permitted to administer a Wechsler Abbreviated Scale of Intelligence (WASI)17 to estimate the intelligence quotient (IQ). Significant cognitive impairment for this protocol was defined as an estimated IQ below 80.
  • Subjects with chronic medical illnesses including seizure disorder (excluding a history of febrile seizures), severe hypertension, thyroid disease, structural cardiac disorders, serious cardiac conditions, serious arrhythmias, cardiomyopathy, glaucoma, Tourette's Disorder, family history of Tourette's Disorder or tics.
  • Use of monoamine oxidase inhibitors within 30 days of the screening visit.
  • Use of any psychotropic medication (except sedative hypnotics prescribed as a sleep aid at a stable dose for at least 30 days prior to screening, at bedtime only). Use of stimulant medication for control of ADHD at screening was permitted if inclusion criterion number 6 was met.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Swanson, Kotin, Agler, M-Flynn, and Pelham Rating Scale (SKAMP)-Combined Scores at Hour 4 Post-Dose
Time Frame: Hour 4 post-dose
The SKAMP scale measures 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 is 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 is 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.
Hour 4 post-dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Onset and Duration of Clinical Effect Based on SKAMP-Combined Scale
Time Frame: 0.75, 2, 8, 10, 12 hours post-dose
Onset and duration is determined using SKAMP combined rating scale at each post-dose time point. Onset of effect is defined as first assessment time showing statistical significance (i.e. p is less than or equal to [=<] 0.05) between NWP06 and placebo and duration of effect is defined as the as last consecutive time-point at which difference is still statistically significant between NWP06 and placebo. SKAMP scale measures the manifestations of ADHD using an independent observer rating of the participant's impairment in classroom observed behaviors. SKAMP combined score is 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 is obtained by summing up each item score where each item is 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.
0.75, 2, 8, 10, 12 hours post-dose
SKAMP Attention Subscale Score Over 12 Hours
Time Frame: 0.75, 2, 4, 8, 10, 12 hours post-dose

SKAMP combined score is obtained by summing up each item score where each item is 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. SKAMP attention subscale is 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.
0.75, 2, 4, 8, 10, 12 hours post-dose
SKAMP Deportment Subscale Score Over 12 Hours
Time Frame: 0.75, 2, 4, 8, 10, 12 hours post-dose

SKAMP combined score is 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 is obtained by summing up each item score where each item is 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. SKAMP deportment subscale is 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 hours post-dose
Permanent Product Measure of Performance (PERMP) Score Over 12 Hours
Time Frame: 0.75, 2, 4, 8, 10, 12 hours post-dose
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 a participant's performance. The total score range from 0-160 with higher scores indicating better performance.
0.75, 2, 4, 8, 10, 12 hours post-dose
SKAMP Combined Scores Over 12 Hours
Time Frame: 0.75, 2, 8, 10, 12 hours post-dose
