Primary Outcome Measures:
  • Mean Change (Week 8 - Baseline) in the Autistic Behavior Checklist (ABC) Irritability Subscale Score [ Time Frame: Week 8 ]
    The ABC is a 58-item informant-based assessment of problem behaviors in children/adolescents with mental retardation. Items are rated on a 4-point scale (0=no problem, 3=severe problem), and resolve into 5 domain subscales. A decrease in score indicates improvement.


Secondary Outcome Measures:
  • Mean Clinical Global Impressions Improvement Scale (CGI-I) Score [ Time Frame: Week 8 ]
    The CGI scale is a clinician-rated global assessment of a patient's improvement over time. Baseline assessment rated a patient's condition on a 7-point scale (1=no symptoms, 7=very severe symptoms). Subsequent assessed improvement relative to baseline symptoms on a 7-point CGI-I item scale (1=very much improved, 7=very much worse).

  • Number of Participants With Response at Week 8 [ Time Frame: Week 8 ]
    Response defined as a ≥ 25% reduction from baseline to endpoint in the ABC Irritability Subscale score and a CGI-I score of 1 or 2 at endpoint

  • Mean Change (Week 8 - Baseline) in the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS; Compulsion Scale Only) [ Time Frame: Week 8 ]
    CY-BOCS=10-item assessment of obsessive-compulsive symptoms in patients <18 years. 5 items pertaining to compulsions rate symptoms (time spent, interference with functioning, distress, resistance, control) on a 5-point scale (0=no symptoms/minimum severity, 4=extreme symptoms/maximum severity). A decrease in value indicates improvement.

  • Mean Change (Week 8 - Baseline) in the Other ABC Subscale Scores [ Time Frame: Week 8 ]
    Mean change (Week 8 - baseline) in the other ABC subscale scores (lethargy/social withdrawal; stereotypic behavior; hyperactivity/ noncompliance; inappropriate speech). A decrease in value indicates improvement

  • Mean Change (Week 8 - Baseline) in CGI-Severity (CGI-S) [ Time Frame: Week 8 ]
    A CGI-S assessment (a 7-point scale to evaluate the severity of symptoms) was performed at baseline (1=no symptoms; 7=very severe symptoms). The patient's improvement relative to the symptoms at baseline on were assessed on a 7-point CGI-I (1=very much improved; 7=very much worse). A decrease in value indicates improvement.

  • Summary of Safety [ Time Frame: continuous throughout the study ]
    Deaths, Adverse Events (AEs), Serious AEs (SAEs), Treatment-Emergent AEs and AEs leading to discontinuation

  • Change From Baseline in Body Weight [ Time Frame: Week 8 ]
    Adjusted mean change (Week 8 - baseline) in body weight
