Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Effect of SPN-810 Treatment on the Frequency of Impulsive Aggression (IA) Behaviors Measured by the Impulsive Aggression Diary | Daily measure from Visit 2 (Day -15) to Visit 7 (Day 36) for a total of 7 weeks | 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 7, 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. |
| Secondary | Effect of SPN-810 on Impulsive Aggression (IA) Measured by Clinical Global Impression - Severity Scale (CGI-S) | From Baseline/Visit 3 (Day 1) to Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29), Visit 7 (Day 36) | 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 four time points: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36). |
| Secondary | Effect of SPN810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Total Score | From Baseline/Visit 3 (Day 1) to Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36). | 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. Data represent the total score change between the Baseline (Visit 3/Day 1) and four time points: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29), and Visit 7 (Day 36). |
| Secondary | Effect of SPN-810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Remission Rate | Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36) | The treatment effect on the R-MOAS was assessed to capture the severity of the aggressive behaviors. The remission rate was defined as percentage of subjects with a R-MOAS total score ≤ 10. Data represent the percentage of subjects at four time points during the treatment period: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36). |
