Atomoxetine, Placebo and Parent Management Training in Autism

The study will evaluate the effectiveness of atomoxetine (Strattera) with and without Parent Management Training (PMT) in children with Autism, Asperger's Disorder, or Pervasive Developmental Disorder Not Otherwise Specified (PDDNOS) who have symptoms of Attention Deficit Hyperactivity Disorder (ADHD). This is a double-blind placebo, parallel study where the atomoxetine will have a dose titration over a 6 week period. All children will be seen weekly during this titration period, with additional visits at Week 8 and Week 10. Families assigned to the PMT arm will have an additional weekly meeting with a clinician for a total of 9 PMT visits. PMT involves teaching parents to implement behavioral interventions with their children. Subjects who are clinical responders (ADHD Responders and Compliance Responders) from the 10 week study period will be followed every 4 weeks in a 24-week extension study. Subjects who are clinical nonresponders will continue in PMT if they received PMT during the double-blind phase, and they will receive an open trial of atomoxetine if they were on placebo during the double-blind phase. All subjects (responders and nonresponders) will be invited to participate in follow-up assessments every 4 weeks for 24 weeks after the completion of the double-blind phase.

Primary outcomes

  1. Percentage of Participants Who Were Attention Deficit Hyperactivity Disorder (ADHD) Respondents

    Time frame: week 10

    Respondents were defined as having ≥30% decrease on the SNAP and CGI-I<=2). The Swanson, Nolan, and Pelham (SNAP)-IV Parent and Teacher Rating Scales were used to measure ADHD and oppositional symptoms at home and school. The SNAP-IV ADHD section contains items for each of the 18 Diagnostic and Statistical Manual of Mental Disorders-IV symptoms of ADHD rated from 0 (not at all) to 3 (very much). The Clinical Global Impressions Scale (CGI) includes subscales for severity of illness and global improvement. The Severity scale is scored from 1 (normal) to 7 (extremely ill), with a rating of ≥4 required for inclusion. The Improvement score ranged from 1 (very much improved) through 4 (no change) to 7 (very much worse). The CGI was completed by a blinded rater based on parent/child interview and review of completed parent and school behavior problem questionnaires at each study visit.

  2. Percentage of Participants Who Were Autism Spectrum Disorder Respondents

    Time frame: week 10

    Respondents were defined as having ≥30% decrease on the HSQ and CGI-I≤2). The 25-item HSQ was adapted by the Research Units on Pediatric Psychopharmacology Autism Network to evaluate behavioral noncompliance in children with autism spectrum disorder (ASD). The Home Situations Questionnaire - Pervasive Developmental Disorder (HSQ) is a 25-item parent rating scale assessing noncompliance. Parents are asked to indicate whether each item is a problem and, if so, its severity from 1 (mild) to 9 (severe). The School Situations Questionnaire (SSQ) is a 9-item teacher rating scale that assesses noncompliance. The SSQ is a companion instrument to the HSQ and uses the same rating scale.

    The Clinical Global Impressions Scale (CGI) includes subscales for severity of illness and global improvement. The Severity scale is scored from 1 (normal) to 7 (extremely ill),
