About this study

The purpose of this open label study in children and adolescents with autism spectrum disorders (ASD) is to examine the acute (12 week) and long-term (1 year) effects of aripiprazole on problem behaviors associated with ASD and development in three behavioral domains which appear particularly affected by ASD. We are also examining the safety and tolerability of aripiprazole in a range of children with autism. 20 children will be enrolled in the treatment part of the study. An additional 10 children, self selected by guardian desire not to pursue pharmacological treatment, will serve as a nonrandomized control group. This group will be provided with support but not any other treatments, come in for fewer visits and will be asked not to seek pharmacologic treatment outside the study. As of January 2010, we have completed enrollment in the treatment arm. Currently, we are only looking to enroll individuals in the control arm in which participants would not take any psychiatric medication.

Primary outcomes

  1. Change From Baseline in Aberrant Behavior Checklist-Irritability at 12 Weeks

    Time frame: Baseline to 12 weeks

    The Aberrant Behavior Checklist (ABC) is a caregiver rated questionnaire for assessing problem behaviors of children over the past week relative to typically developing children of the same age. Problem behaviors are rated on a categorical scale between 0 not at all a problem and 3 problem is severe in degree. Raters are instructed to consider both the severity and the frequency of the behavior in determining how severe a problem the behavior is. Thus, if a given behavior occurs more often than in other children of the same age and sex, scores greater than or equal to 1 are warranted. The total score can range from a minimum of 0 (no problem behaviors) to a maximum of 174, higher the number the worse the symptoms.The irritability subscale consists of 15 items with a minimal score of 0 - no irritability problems to 45 - all irritability items rated as severe. A rating of 18 or more on the irritability subscale is considered clinically significant.

Secondary outcomes

  1. Clinical Global Impressions Scale - Severity Score (CGI-S)

    Time frame: Baseline to 12 weeks

    One of the most widely used of clinician assessment tools in psychiatry, the CGI is an observer-rated scale that measures illness severity (CGI-S).

    The CGI is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (among the most severely ill patients).

  2. Change From Baseline in the Aberrant Behavior Checklist -Lethargy/Social Withdrawal Subscale at 12 Weeks

    Time frame: Baseline to 12 weeks

    The Aberrant Behavior Checklist lethargy/social withdrawal subscale (ABC-SW) is the sum of ratings from 0 - not a problem at all to 3 - problem is severe in degree on 16 items within the Aberrant Behavior checklist (also described in the primary outcome measure section above). Scores can range from 0 to 48, with higher scores indicating more severe problems. The period for the rating is one week and the reference group is typically developing children of the same age and gender as the participant. Both frequency of the behaviors and severity of the problems related to them are considered. High ratings on these items reflect lack of response and interaction with other people in the child's environment.
