Brief Summary:
This study will determine the effectiveness of mirtazapine in reducing anxiety in children with autistic disorder, Asperger's disorder and Pervasive Developmental Disorder.

Condition or disease Intervention/treatment Phase
Autism Spectrum Disorders Drug: Placebo Drug: Mirtazapine Phase 3

Detailed Description:
One of the areas receiving very little attention in Pervasive Developmental Disorders (PDDs) is that of anxiety. Anxiety is common in PDD, but has not yet been fully characterized. The primary objective of this study is to conduct a preliminary placebo-controlled trial of mirtazapine for the treatment of anxiety associated with PDDs. We hypothesize that mirtazapine will be safe and well tolerated.

Primary Outcome Measures :
  1. Mean 10-Week Change in Pediatric Anxiety Rating Scale 5-Item Total Score, Double-blind Phase [ Time Frame: Weeks Baseline, 2, 4, 6, and 10 ]
    The Pediatric Anxiety Rating Scale (PARS) is a clinician-rated instrument that assesses anxiety symptoms that are commonly associated with social anxiety, separation anxiety, and generalized anxiety disorders. Scaled score ranges form 0-25 with higher scores indicating more severe anxiety symptoms. Means were estimated using a repeated measures linear regression model with treatment group, study week (in categories), and their interaction as covariates, and assuming a common mean between treatment groups at baseline. Confidence intervals reflect a Bonferroni multiple testing correction accounting for the selection of two primary outcomes.

  2. Proportion of Participants Who Responded to Treatment at 10 Weeks According to the Improvement Item of the Clinical Global Impression-Scale (Response Defined as CGI-I=1 or CGI-I=2) [ Time Frame: Screen (Visit 1) Baseline (Visit 2) and Endpoint (Week 10) ]
    The Clinical Global Impressions Global Improvement (CGI-I) is designed to take into account all factors to arrive at an assessment of response to treatment. The CGI-I scale ranges from 1 to 7 (1=very much improved; 2= much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse), with lower scores indicating improvement (1=very much improved and 2=much improved). In this study the CGI was focused on the target symptom of anxiety. Participants with a CGI-I score of 1 or 2 were classified as responders. The CGI-I was administered biweekly for 6 weeks and again at 10 weeks during the study. The participant who withdrew from the study before 10 weeks was not included in the calculations.
