Title: A Double-blind, Placebo-controlled Study, Followed by an Open-label Extension Study Evaluating the Efficacy and Safety of Risperidone (R064766) in Children and Adolescents With Irritability Associated With Autistic Disorder
Brief Summary: The purpose of this study is to evaluate the efficacy of risperidone compared with placebo in children and adolescents with irritability associated with autistic disorder.


Options:
A: Inclusion Criteria:

* medically healthy outpatients between 6 and 12 years of age (cut off: 12 years and 11 months)
* Intelligence Quotient (IQ) equal to or greater than 50 (Stanford-Binet)
* Social Responsiveness Scale (SRS) Total Score equal to or greater than 70
* ability to complete laboratory and cognitive testing
* diagnosis of Autism Spectrum Disorder (ASD) based on expert clinical opinion and confirmed on the Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule (ADOS)
* Clinical Global Impression (CGI) severity rating of 4 or higher
* care provider who can reliably bring participant to clinic visits, provide trustworthy ratings, and interact with the participant on a regular basis
* stable medications for at least 4 weeks
* no planned changes in psychosocial interventions during the trial
* no concurrent participation in any other clinical research trials
* willingness to provide blood samples and electrocardiogram

Exclusion Criteria:

* diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder, or psychotic disorder
* regular nasal obstruction or nosebleeds
* active and unstable medical problems (e.g., migraine; asthma; seizure disorder; anaphylaxis; epilepsy; diabetes; serious liver, renal, or cardiac pathology)
* clinically significant abnormal vital signs or ECG reading
* evidence of a genetic mutation know to cause ASD (e.g., Fragile X Syndrome) or metabolic disorder
* significant hearing or vision impairments
* drinks large volumes of water (e.g., habitual or psychogenic polydipsia)
* pregnant or sexually active females not using a reliable method of contraception (urine pregnancy test will be conducted)
* history of hypersensitivity to vasopressin, its analogs (e.g., Desmopressin), or compounding preservatives (e.g., chlorobutanol)
* current use of any medications known to interact with vasopressin including: 1) carbamazepine (i.e., Tegretol); chlorpropamide; clofibrate; urea; fludrocortisone; tricyclic antidepressants (all of which may potentiate the antidiuretic effect of vasopressin when used concurrently); 2) demeclocycline; norepinephrine; lithium; heparin; alcohol (all of which may decrease the antidiuretic effect of vasopressin when used concurrently); 3) ganglionic blocking agents including benzohexonium, chlorisondamine, pentamine (all of which may produce a marked increase in sensitivity to the pressor effects of vasopressin)
* prior or current use of vasopressin
* abnormal chemistry result
B: Inclusion Criteria:

* Diagnosis of PDD (PDD-NOS, Asperger's Disorder, Autistic Disorder)
* Hyperactivity
* Between ages 5 years 0 months and 13 years 11 months.
* Weight \>/= 15 kg (33 lb)
* A mental age of at least 18 months

Exclusion Criteria:

* Prior failed treatment with an adequate trial of guanfacine in the last 2 years
* Concurrent treatment with another psychoactive medication
C: Inclusion Criteria:

1. Males and females, Aged between 3 and 12 years.
2. Autistic disorder - DSM-IV criteria.
3. A score of at least moderately impaired on the CGI-Severity item.
4. Clinical judgment that medication treatment for autism is indicated.

Exclusion Criteria:

1. Rett's disorder, childhood disintegrative disorder, Asperger's disorder, and PDD, NOS.
2. Psychotic disorder (DSM-IV) (including schizophreniform disorder and schizophrenia).
3. Major depressive disorder (DSM-IV).
4. Bipolar disorder (DSM-IV).
5. History of psychoactive drug in the previous 2 weeks prior to phase 1.
6. A history of treatment with olanzapine for a cumulative period of greater than 2 weeks prior to entering phase 1.
7. Systemic diseases such as cardiac, renal, thyroid diseases, uncontrolled seizure disorder (seizure disorder that is not controlled by anti-epileptic medication - a child who is seizure free for a period of 6 months on a stable dose of antiepileptic drug would be considered controlled), or diabetes mellitus.
8. Children with a known medical cause for autistic disorder.
9. Abnormal fasting blood glucose or history of diabetes.
10. Baseline body mass index (BMI) greater than the 90th percentile for age and gender (CDC growth charts, Kuczmarski et al, 2000) (because of risk of weight gain).
11. Baseline QTc \>450 msec. Note: Historically, patients we evaluate do not have QTc values \>450.
12. Dyskinesias at baseline (per the criteria of Schooler and Kane, 1982).
D: Inclusion Criteria:

* Diagnostic for autistic disorder
* A Clinical Global Impression - Severity (CGI-S) score of =\>4 and an Aberrant Behavior Checklist - Japanese Version (ABC-J) Irritability Subscale score of =\>18
* Patients with mental age of \>18 months as measured by appropriate developmental or mental scales
* Patients who have an appropriate caregiver, eg, parent or study-site personnel, who is able to observe the patient's condition, provide information, and evaluate the patient's response appropriately

Exclusion Criteria:

* Patients with previous or current psychotic disorder (eg, schizophrenia, bipolar disorder, or other psychiatric disorders) or with pervasive developmental disorder not otherwise specified, Asperger's disorder, Rett's disorder, pediatric destructive behavior disorder, or substance dependence
* Patients with a clinically significant endocrine, metabolic, cardiac, hepatic, renal, or pulmonary disorder, or hypertension
* Weight of \<15 kg at the time of screening and baseline
* Patients with QTc\>450 msec in the standard 12-lead electrocardiogram (ECG) at the time of screening
* Patients with known hypersensitivity to risperidone or paliperidone
