Summary:

      The purpose of this study is to develop a better tolerated and more effective pharmacologic
      treatment with individuals with Pervasive Developmental Disorder. This is a double-blind,
      placebo-controlled study of aripiprazole in the management of the maladaptive behaviors of
      Pervasive Developmental Disorder. The investigators hypothesize that aripiprazole will be
      more effective than placebo for reducing aggression, tantrum and self-injurious behavior in
      children with Pervasive Developmental Disorder.

          -  Psychotropic medication-free for at least 2 days prior to screening laboratory tests
             and electrocardiogram (ECG).

          -  Significant irritability as determined by a Clinical Global Impression Severity score
             of greater or equal to 4 (Moderately ill) and a score of equal to or greater than 18
             on the Aberrant Behavior Checklist Irritability Subscale.

             Intelligence Scale for Children (WISC), 4th edition; the Leiter International Test of
             Intelligence-Revised will be used if a child is nonverbal but thought to have an IQ
             greater than or equal to 50.

        Exclusion Criteria:

          -  DSM-IV-TR diagnosis other than PDD NOS (autistic disorder, Asperger's disorder, Rett's
             disorder, or childhood disintegrative disorder), schizophrenia, bipolar disorder or
             substance abuse within the last 6 months.

          -  Comorbid disorder with possible association to autism (e.g., Fragile X Syndrome,
             Tuberous Sclerosis).

          -  A significant medical condition such as heart, liver, renal, or pulmonary disease, or
             a seizure disorder, as determined by history, physical examination, or laboratory
             testing.

          -  Subjects with an active seizure disorder (history of febrile seizures in early
             childhood will be considered.

          -  Evidence of a prior adequate trial of aripiprazole (defined as equal to or greater
             than 2 weeks at equal to or greater than 5 mg per day. When there is not evidence of a
             prior adequate trial, subjects must be medication-free for a least 2 weeks prior to
             baseline.

          -  History of neuroleptic malignant syndrome.

          -  Subjects who, in the opinion of the investigator, are unsuitable in any other way to
             participate in this study, including being unable to comply with the requirements of
             the study for any reason.
