Brief Summary:
A study to evaluate the efficacy and safety of dasotraline in children 6 to 12 years of age with Attention-Deficit Hyperactivity Disorder (ADHD) in a simulated classroom setting.

Condition or disease Intervention/treatment Phase
Attention-Deficit Hyperactivity Disorder (ADHD) Drug: dasotraline Drug: Placebo Phase 3

Detailed Description:

This is a randomized, double-blind, placebo-controlled, parallel-group, efficacy and safety study in children with ADHD in a laboratory classroom setting. The study will be comprised of 3 periods: Screening (up to 35 days) including a 3 - 5 day ADHD medication washout prior to Day -1; Double-blind randomized treatment with either dasotraline (2 mg/day) or placebo for 14 days; and a final safety evaluation 7 days after last dose. Prior to the start of treatment (Day 1) and following the conclusion of the double-blind period (Day 15), subjects will undergo a full-day laboratory classroom evaluation in cohorts of up to 18 subjects. Each laboratory classroom day will include seven 30-minute simulated classroom sessions where trained observers will assess subjects using the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) Scale. In addition during each classroom session, a 10-minute math test (Permanent Product Measure of Performance [PERMP]) will be administered to evaluate sustained attention and effort. Seven (± 2) days after the last dose of study drug, subjects will return to the clinic and complete safety assessments.

This study is designed to test the superiority of dasotraline 2 mg/day against placebo based on Swanson, Kotkin, Agler, M-Flynn, and Pelham Scale (SKAMP)-Combined score in pediatric subjects aged 6-12 years with ADHD who weigh ≤ 30 kg

Primary Outcome Measures :
  1. Change From Baseline at Day 15 in , ADHD Symptoms as Measured by Mean Swanson,Kotkin,Agler,M-Flynn, Pelham Rating Scale(SKAMP)-Combined Score Obtained From an Average of the 7 Assessments Collected Across the 12-hour Classroom Day(12 to 24 Hours Postdose) [ Time Frame: Baseline to Day 15 ]
    The Swanson, Kotkin, Agler, M-Flynn, Pelham Rating Scale (SKAMP) scale is a 13-item independent observer rating of subject impairment of classroom observed behaviors. Each item is rated on a 7-point impairment scale (0 = normal to 6 = maximal impairment). The combined scores for the SKAMP are obtained by summing the values of all 13 items in the assessment. The range of SKAMP combined score is 0-78, with higher values represent a worse outcome.


Secondary Outcome Measures :
  1. Change From Baseline at Day 15 in Mean Swanson, Kotkin, Agler, M-Flynn, and Pelham Rating Scale (SKAMP)Attention Subscale Score Obtained From the 7 Assessments Collected Across the 12-hour Classroom Day (12 to 24 Hours Postdose) [ Time Frame: Baseline to Day 15 ]
    The Swanson, Kotkin, Agler, M-Flynn, Pelham Rating Scale (SKAMP) scale is a 13-item independent observer rating of subject impairment of classroom observed behaviors. Each item is rated on a 7-point impairment scale (0 = normal to 6 = maximal impairment). The Attention Subscale scores for the SKAMP are obtained by summing the values of Items 1-4 in the assessment. The range of SKAMP Attention Subscale score is 0-24, with higher values represent a worse outcome.

  2. Change From Baseline at Day 15 in Mean Swanson, Kotkin, Agler, M-Flynn, and Pelham Rating Scale (SKAMP)-Deportment Subscale Score Obtained From the 7 Assessments Collected Across the 12-hour Classroom Day (12 to 24 Hours Postdose) [ Time Frame: Baseline to Day 15 ]
    The Swanson, Kotkin, Agler, M-Flynn, Pelham Rating Scale (SKAMP) scale is a 13-item independent observer rating of subject impairment of classroom observed behaviors. Each item is rated on a 7-point impairment scale (0 = normal to 6 = maximal impairment). The Deportment Subscale scores for the SKAMP are obtained by summing the values of Items 5-8 in the assessment. The range of SKAMP Deportment Subscale score is 0-24, with higher values represent a worse outcome.

  3. Change From Baseline at Day 15 in Mean Permanent Product Measure of Performance (PERMP)-Attempted Problems Scores Obtained From the 7 Assessments Collected Over the 12-hour Classroom Day (12-24-hours Postdose) [ Time Frame: Baseline to Day 15 ]
    The Permanent Product Measure of Performance (PERMP) is a math test consisting of 400 problems. Both attempted problems and correct problems are assessed. Subjects are to complete as many problems as possible in 10 minutes. Performance is measured by the number of math problems attempted and the number of math problems correctly completed. The minimum possible score is 0. The highest possible score is 400, with higher scores mean higher performance and less severe ADHD symptoms.

  4. Change From Baseline at Day 15 in Mean Permanent Product Measure of Performance (PERMP)-Correct Problems Scores Obtained From the 7 Assessments Collected Over the 12-hour Classroom Day (12-24-hours Postdose) [ Time Frame: Baseline to Day 15 ]
    The Permanent Product Measure of Performance (PERMP) is a math test consisting of 400 problems. Both attempted problems and correct problems are assessed. Subjects are to complete as many problems as possible in 10 minutes. Performance is measured by the number of math problems attempted and the number of math problems correctly completed. The minimum possible score is 0. The highest possible score is 400, with higher scores mean higher performance and less severe ADHD symptoms.

For any subject receiving monotherapy stimulant treatment for ADHD, that treatment must be well tolerated and clinically effective based on clinical assessment and informant interview, as well as, review of available medical records. Note: The ADHD Rating Scale Version IV - Home Version (modified for investigator administration) (ADHD RS IV HV) will be administered at Screening by the investigator to inform clinical evaluation.

  24. Subject is currently undergoing ongoing or newly initiated Cognitive Behavioral Therapy (CBT) for the treatment of ADHD; behavioral therapies, including school based interventions that were initiated less than one month prior to screening; or, behavioral therapy that in the opinion of the investigator would interfere with the subject's ability to participate for the duration of the study. School based interventions that have been in place for more than one month prior to screening will be allowed. Note: Unavoidable changes in school-based interventions that occur during study participation will not be exclusionary, but should be documented by the investigator, to the extent possible. Subjects should not be enrolled who, in the judgment of the investigator, are expected to start substantially different or more intensive course of behavioral therapy over the duration of their participation in the study.
  25. Subject or subject's family anticipates a move outside the geographic range of investigative site during the study period, or plans extended travel inconsistent with the recommended visit interval during study duration.
