NCT02691182

Brief Summary

Children between the ages of 6-12 years who are diagnosed with impulsive aggression comorbid with ADHD and have participated in the 810P301 or 810P302 study were invited to participate in this study. This was a Phase 3 open-label extension (OLE) study to collect long-term safety data on the use of SPN-810 in treating impulsive aggression in pediatric subjects with ADHD when taken in conjunction with standard ADHD treatment. After confirmation of eligibility, all subjects were treated with SPN-810. Subjects were given a choice to extend participation in this study every 6 months for up to 36 months.

Outcome Measures

Primary Outcomes (3)

  • Effect of SPN810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Total Score

    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.

    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).

  • Effect of SPN810 on Impulsive Aggression (IA) 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 from baseline to each visit during the study. The baseline score represents the total score at the last visit of each double-blind study.

    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).

  • Effect of SPN810 on Impulsive Aggression (IA) Measured by Clinical Global Impression - Improvement Scale (CGI-I)

    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.

    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).

Study Arms (1)

Open-label treatment with SPN-810

EXPERIMENTAL

Subjects aged 6-17 years were treated with SPN-810 starting on day 1 with 18 mg/day. The clinician was able to adjust the dose of SPN-810 throughout the study based on subject's response and tolerability within the limits of 6 mg/day and 36 mg/day or, up to 54 mg/day for subjects with a body weight ≥ 30 kg. The subjects were given a choice of extending their participation in the study every 6-month period for up to 36 months

Drug: SPN-810

You may not qualify if:

  • Body Mass Index (BMI) in 99th percentile or above.
  • Clinically significant change in health status, safety concern or any other reason that, in the opinion of the Sponsor or the Investigator, would prevent the subject from participating in this study or successfully completing this study.
  • Pregnancy or refusal to practice contraception during the study (for female subjects of childbearing potential and sexually active males).
  • Current substance or alcohol use.
  • Suicidal thoughts or behaviors confirmed at Visit 7 for 810P301 or 810P302, Visit 8 for 810P503 or Visit 6 for 810P204 studies.
