What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Efficacy and Safety of SPN-810 on the Frequency of Impulsive Aggression (IA) Measured by the Impulsive Aggression Diary

    The primary efficacy endpoint was percent change (PCHT) in the frequency (unweighted score) of IA behaviors per 7 days in the treatment (titration and maintenance) period relative to the Baseline period calculated over the number of days with non-missing IA diary data. PCHT was then calculated as 100 x (T - B)/B, where T and B are IA behavior frequencies per 7 days during the treatment period (from Day 2 through Visit 6, inclusive) and baseline period (Day ≤1), respectively. The IA behavior frequency per 7 days is defined as (SUM/DAY) x 7, where SUM is the total of the IA behaviors reported in the subject IA diary, and DAY is the number of days with a non-missing IA score in the subject IA diary during the specified study period.

    Measured: Daily measure from Visit 2 (Week -2) to Visit 6 (Week 5) for a total of 7 weeks

Secondary outcomes (7)
  1. Effect of SPN-810 on Impulsive Aggression Measured by Clinical Global Impression - Severity Scale (CGI-S)

    The Clinical Global Impression - Severity of Illness (CGI-S) is a single item clinician rating of clinician's assessment of the severity of IA behaviors CGI-S was evaluated by the Investigator at each visit on a 7- point scale with 1=Normal, 2=Borderline ill, 3=Mildly ill, 4=Moderately ill, 5=Markedly ill, 6=Severely ill, and 7=Extremely ill. Data represent the change between Baseline (Visit 3/Day 1) and three time points: Visit 4 (Week 1); Visit 5 (Week 2) and Visit 6 (Week 5).

    Measured: Baseline/Visit 3 (Day 1), Visit 4 (Week 1), Visit 5 (Week 2), and Visit 6 (Week 5). The total duration of the study was 5 weeks.

  2. Effect of SPN-810 on Impulsive Aggression Measured by Clinical Global Impression-Improvement (CGI-I) Scale Investigator Rated

    The Clinical Global Impression - Improvement Scale (CGI-I) is an assessment of how much the patient's illness has improved or worsened relative to a baseline state at the beginning of treatment.

    CGI-I was evaluated by the Investigator at each visit on a 7-point scale with 1=very much improved, 2= much improved, 3= minimally improved, 4= no change, 5= minimally worse, 6= much worse, 7= very much worse

    Measured: Visit 4 (Week 1), Visit 5 (Week 2) and Visit 6 (Week 5), a total of 4 weeks

  3. Effect of SPN-810 on Impulsive Aggression Measured by Child Health Questionnaire Parent Form 28-item (CHQ-PF28)

    The CHQ-PF28 is a short generic measure of health status and health-related quality of life. The 28 items have 4, 5, or 6 response options, divided over 8 multi-item scales (physical functioning, general behavior, mental health, self-esteem, general health perceptions, parental impact: emotional, parental impact: time, and family activities) and 5 single item concepts (role functioning: emotional/behavior, role functioning: physical, bodily pain, family cohesion, and change in health). In addition, the individual scale scores will be aggregated to derive 2 summary component scores: the physical functioning and psychosocial health summary scores. The range on subscales and the overall scale is 0-100 (0 = worst possible health state; 100 = best possible health state).

    Data represent the change from Baseline (Visit 3) to one time point, Visit 6 (Week 5).

    Measured: Baseline Visit 3 (Day 1) and Visit 6 (Week 5). Total duration of the study was 5 weeks.

  4. Effect of SPN-810 on Impulsive Aggression Measured by Parenting Stress Index, Fourth Edition, Short Form (PSI-4-SF)

    The PSI-4-SF is a 36-item self-report measure of parenting stress. Three subscales Parental Distress (PD), Parent-Child Dysfunctional Interaction (P-CDI), and Difficult Child (DC) consist of 12 items each. Parent chooses one of the 5 responses against each item. The 5 responses are: Strongly Agree (SA), Agree (A), Not Sure (NS), Disagree (D), and Strongly Disagree (SD) to indicate the degree to which they agree with each statement. The PD subscale raw score ranges from 12-60, P-CDI and DC each subscale raw score ranges from 16-56. The total stress raw score is the sum of the three subscales (PD+P-CDI+ DC) with a minimum score of 44 and a maximum score of 172. The total stress score is then converted into the percentile score. Parents with a 91st percentile or higher are experiencing clinically significant levels of stress. Data represents the mean change in percentile score from Baseline (Visit 3) and one time point, Visit 6 (Week 5).

    Measured: Baseline Visit 3 (Day 1) and Visit 6 (Week 5). Total duration of the study was 5 weeks.

  5. Effect of SPN-810 on Impulsive Aggression Measured by Clinical Global Impression-Improvement (CGI-I) Scale Caregiver Rated

    The CGI scale was developed to provide a brief, stand-alone assessment of the clinician's view of a subjects' global functioning prior to and after administration of a study medication. The scale was also rated by the Caregiver to assess the improvement of IA behaviors.

    . CGI-I was evaluated by the Caregiver at each visit on a 7-point scale with 1=very much improved, 2= much improved, 3= minimally improved, 4= no change, 5= minimally worse, 6= much worse, 7= very much worse

    Measured: Visit 4 (Week 1), Visit 5 (Week 2) and Visit 6 (Week 5), a total of 4 weeks

  6. Effect of SPN-810 on Impulsive Aggression Measured by the Swanson, Nolan, Pelham Rating Scale- Revised (SNAP-IV) Rating Scale

    The Swanson, Nolan, Pelham Rating Scale-Revised (SNAP-IV) includes 18 ADHD and 8 oppositional defiant disorder (ODD) symptoms. The symptoms are scored on a 4-point scale, not at all=0, just a little=1, Quite a bit= 2, very much=3. The ratings from the SNAP-IV scale are grouped into the following 4 subscales: ADHD Inattention (items #1-9), ADHD Hyperactivity/Impulsivity (items#10-18), ODD (items# 19-26), and ADHD-combined (first two scales combined, items #1-18). Each observed subscale score is the average rating of the items scores for the subscale where scores range from 0-3; the higher is the score, worsen is the outcome.

    Data represent the change of the observed scores between Baseline (Visit 3) and the end of the study, Visit 6 (Week 5).

    Measured: Baseline Visit 3 (Day 1) and Visit 6 (Week 5). Total duration of the study was 5 weeks.

  7. Effect of SPN-810 on Impulsive Aggression Measured by the Percentage of Responders

    A Responder was defined as a subject with at least a 30% or 50% reduction in the frequency of IA behaviors per 7 days in the Treatment (Titration and Maintenance) period relative to the Baseline period per the IA Diary.

    Data represent the percentage of subjects with 30% and 50% reduction in IA behaviors from Baseline to end of treatment period.

    Measured: Daily measure from Visit 2 (Week -2) to Visit 6 (Week 5) for a total of 7 weeks
