measure: Effect of SPN810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Total Score; description: R-MOAS scale gauges the severity of aggressive behavior: the frequency of the 16 behaviors is rated over the past week in 4 areas (VE, PH, PR, SE). For each open question in each area, the parent-rated the aggressive behaviors on a scale from 0 to 5 or more times. To each area corresponds a weighted category: Verbal Incidents (VE)=1, Incidents Toward Other (PH) =4, Incidents Involving Property (PR)=2 and Incidents Directed Toward Self (SE)=3. Therefore, the sum of each area yields a maximum weighted score of 20 (VE), 120 (PH), 60 (PR), and 90 (SE). The total score is the sum of the four area scores or 0-290; the higher the score, the more severe the aggressive behavior is. The data represent the total score change from baseline at each visit for the duration of the study, a total of 60 months. The baseline score represents the total score at the last visit of each double-blind study.; timeFrame: 17-time points: Months 3 (V5), 6 (V6), 9 (V7), 12 (V8), 15 (V9), 18 (V10), 21 (V11), 24 (V12), 27 (V13), 30 (V14), 33 (V15), 36 (V16), 39 (V17), 42 (V18), 45 (V19), 48 (V20) and month 60 (Visit 24).; measure: Effect of SPN810 on Impulsive Aggression (IA) Measured by Clinical Global Impression - Severity Scale (CGI-S); description: 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 from baseline to each visit during the study. The baseline score represents the total score at the last visit of each double-blind study.; timeFrame: 20-time points: Week 2 (V2), Week 4 (V3), Week 8 (V4), Months 3 (V5), 6 (V6), 9 (V7), 12 (V8), 15 (V9),18 (V10), 21 (V11), 24 (V12), 27 (V13), 30 (V14), 33 (V15), 36 (V16), 39 (V17), 42 (V18), 45 (V19), 48 (V20) and month 60 (Visit 24).; measure: Effect of SPN810 on Impulsive Aggression (IA) Measured by Clinical Global Impression - Improvement Scale (CGI-I); description: The Clinical Global Impression - Improvement Scale (CGI-I) is a clinician's assessment of how much the IA behaviors have 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. Data represent the score at each visit during the study.; timeFrame: 20-time points: Week 2 (V2), Week 4 (V3), Week 8 (V4), Months 3 (V5), 6 (V6), 9 (V7), 12 (V8), 15 (V9),18 (V10), 21 (V11), 24 (V12), 27 (V13), 30 (V14), 33 (V15), 36 (V16), 39 (V17), 42 (V18), 45 (V19), 48 (V20) and Month 60 (Visit 24).
