Trial of Aripiprazole in the Treatment of CD in Adolescents
The proposed study will be a 6-week open label study evaluating aripiprazole in the treatment of 12 male post-pubertal adolescents (13-17 years, Tanner Stage 4) diagnosed with conduct disorder. The initial dose depending on the weight of the patient will be as follows: < 25 kg = 1 mg/d; 25-50 kg = 2 mg/d; 50-70 kg = 5 mg/d; > 70 kg = 10 mg/d (Data on File, 2003, Bristol-Myers Squibb). For the first two weeks of the study, the dose will be flexible based on response and tolerance and thereafter will remain fixed.
The use of atypical antipsychotics in children began in 1992 with several small case series with clozapine. Since that time, five other atypical agents, risperidone, olanzapine, quetiapine, ziprasidone and aripiprazole have been introduced into the US market. The newer atypical agents are not associated with agranulocytosis that has limited the usefulness of clozapine. Among the atypical antipsychotics, risperidone has remained the most extensively studied in children and adolescents, for a variety of problems, including Tourette's disorder, conduct disorder, schizophrenia, aggression, and pervasive development disorder. Risperidone has been shown to be an effective treatment in many of these disorders. However, weight gain, hyperprolactinemia, and extrapyramidal symptoms (EPS) are troublesome adverse effects more commonly associated with risperidone such that the drug's utility in this aged patient population is limited. We expect that the utility of aripiprazole in treating the pediatric population will not be limited by adverse effects like the other atypical antipsychotics.

Medical and Biotech [MESH] Definitions
A repetitive and persistent pattern of behavior in which the basic rights of others or major age-appropriate societal norms or rules are violated. These behaviors include aggressive conduct that causes or threatens physical harm to other people or animals, nonaggressive conduct that causes property loss or damage, deceitfulness or theft, and serious violations of rules. The onset is before age 18. (From DSM-IV, 1994)
A personality disorder whose essential feature is a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood. The individual must be at least age 18 and must have a history of some symptoms of CONDUCT DISORDER before age 15. (From DSM-IV, 1994)
An indole derivative effective in schizophrenia and other psychoses and possibly useful in the treatment of the aggressive type of undersocialized conduct disorder. Molindone has much lower affinity for D2 receptors than most antipsychotic agents and has a relatively low affinity for D1 receptors. It has only low to moderate affinity for cholinergic and alpha-adrenergic receptors. Some electrophysiologic data from animals indicate that molindone has certain characteristics that resemble those of CLOZAPINE. (From AMA Drug Evaluations Annual, 1994, p283)
A disorder whose predominant feature is a loss or alteration in physical functioning that suggests a physical disorder but that is actually a direct expression of a psychological conflict or need.
A disorder beginning in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual. (DSM-IV)
