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.
Safety Assessments include: Adverse Events, clinical lab tests, vital signs, physical examinations, ECGs, Simpson-Angus Scale, Barnes Akathisia Scale, Abnormal Involuntary Movement Scale (AIMS) and Columbia Suicise Severity Rating Scale (C-SSRS)
The Nisonger Child Behavior Rating Form (NCBRF) is an instrument designed to assess the behavior of children with intellectual or developmental disabilities. The NCBRF-TIQ is a 66-item behavior rating form designed to assess the behavior of children and adolescents with typical development. The NCBRF is made up of three sections: I, Where raters can identify unusual circumstances that may have affected the youth's behavior; II, where positive behaviors are rated, and III, a listing of problem behaviors. There are separate Teacher and Parent versions of the form, and the NCBRF takes about 15 minutes to complete. The NCBRF is designed to be used with children and adolescents ages 3 to 16 years. The lowest score is a "0" and the highest score is "198". A higher score of the Conduct Problem Subscale score means a worse outcome. A change or negative score means improvement. Data represent the change from baseline (Visit 1) and 11 time points (Visit 2 to Visit 12).
