Title: A Multicenter Double-Blind, Randomized, Placebo-Controlled, Flexible-Dosed, Parallel-Group Study of Aripiprazole Flexibly Dosed in the Treatment of Children and Adolescents With Autistic Disorder (AD)
Brief Summary: This study will compare the effectiveness (how well the drug works) of aripiprazole, flexibly dosed with a placebo, in reducing serious behavioral problems in children and adolescents with a diagnosis of autistic disorder (AD).


Options:
A: Inclusion Criteria:

* Age 4 to 12 years.
* Diagnosis of autistic disorder, Asperger's disorder, or PDD NOS.
* If taking concomitant psychotropic medications, the medication must be at a constant dose for 60 days with no dose changes planned for the duration of the trial.
* Able to swallow capsules.

Exclusion Criteria:

* Presence of any medical condition that significantly increases risk or hampers assessment (e.g., unstable hypertension or cardiac disease, unstable asthma, kidney disease, unstable seizure disorder, pregnancy or any other medical condition as determined by the investigator).
* Weight \< 15 kg.
* Subjects taking concomitant medications or supplements known for their glutamatergic effects (e.g., dextromethorphan, D-cycloserine, amantadine, memantine, lamotrigine, riluzole) or antioxidant properties (high dose vitamin supplements, DMG, TMG, many alternative treatments) within 30 days of the baseline visit with the exception of short term use of dextromethorphan as needed as a cough suppressant. The use of this medicine must be stopped at least 7 days prior to the baseline visit. Regular multivitamins will be allowed.
* Subjects taking daily acetaminophen or nonsteroidal anti-inflammatory drugs within 30 days of the baseline visit.
* Profound mental retardation as evidenced by a mental age below 18 months.
* Subjects taking concomitant medications with the potential for pharmacokinetic or pharmacodynamic drug-drug interactions (e.g., carbamazepine) within 30 days of the baseline visit.
* Subjects who are likely to experience significant changes in their ongoing psychosocial or medical treatments for autism over the course of the trial (e.g., initiation of new behavioral therapy, initiation of new medication or alternative treatment \[e.g., chelation\]). Minor changes in ongoing treatment (e.g., missed therapy sessions due to holiday/vacation; planned break in therapy due to school holidays) will not be considered significant.
* History of prior treatment with NAC.
* Evidence of hypersensitivity/allergy to NAC.
* Presence of certain neurodevelopmental disorders such as Fragile X Syndrome, Tuberous Sclerosis, or other neurological disorders known to be associated with autism or autistic features.
* Diagnosis of Rett's disorder, childhood disintegrative disorder, schizophrenia, bipolar disorder, another psychotic disorder, or substance abuse disorder.
B: Inclusion Criteria:

* Meets current Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition (DSM-IV) diagnostic criteria for AD and demonstrates serious behavioral problems. Diagnosis confirmed by Autism Diagnostic Interview- Revised (ADI-R)
* CGI score \> = 4 AND and Aberrant Behavior Checklist (ABC) Irritability/Agitation subscale score \> = 18 at screening and baseline (randomization)
* Mental age of at least 18 months
* Male or female 6 to 17 years of age, inclusive, at the time of randomization

Exclusion Criteria:

* Patients considered treatment resistant to neuroleptic medication based on lack of therapeutic response to 2 different neuroleptics after treatment of at least 3 weeks each.
* Patients previously treated and not responding to aripiprazole treatment
* The patient is currently diagnosed with another disorder on the autism spectrum, including PDD-NOS, Asperger's Disorder, Rett's Disorder, Fragile-X Syndrome or Childhood Disintegrative Disorder
* Current diagnosis of bipolar disorder, psychosis, or schizophrenia, or major depression
* A seizure in the past year
* History of severe head trauma or stroke
* Patients undergoing non-pharmacologic therapies (e.g., psychotherapy, behavioral modification) must have started at least 2 months prior to the initial screening visit and must remain in a consistent treatment program for the duration of the study.
C: Inclusion Criteria:

* Subject meets the DSM-5 criteria for ASD for an autism diagnosis and is confirmed using ADOS-2 criteria
* SRS-2, proxy version, total t-score \>=66 at screening
* A full scale IQ score \>=70 on the WASI®-II
* Subject has an appropriate study partner, in the opinion of the investigator
* For women of childbearing potential: agreement to remain abstinent or use a contraceptive method with a failure rate of \<1% per year during the treatment period and for at least 28 days after the last dose of study drug
* Treatment with permitted medications (at a stable dose for 12 weeks before screening) and behavioral therapy regimens (regimens stable for 6 weeks before screening), with the intent that such treatments remain stable throughout the study and with no expected changes before the Week 24 visit

Exclusion Criteria:

* Pregnancy or breastfeeding, or intention to become pregnant during the study
* Previous initiation of new or major change in psychosocial intervention within 6 weeks prior to screening
* Unstable or uncontrolled clinically significant affective or psychotic disorders and/or neurologic disorder that may interfere with the assessment of safety or efficacy endpoints
* Substance use disorders during the last 12 months
* Significant risk for suicidal behavior, in the opinion of the investigator
* Epilepsy or seizure disorder considered not well controlled within the past 6 months or changes in anticonvulsive therapy within the last 6 months
* Clinical diagnosis of peripheral neuropathy
* Within the last 2 years, unstable or clinically significant cardiovascular disease
* Uncontrolled hypertension
* Unexplained syncopal episode within the last 12 months
* Confirmed elevation above upper limit of normal of CK-MB, high sensitivity cardiac troponin T, cardiac troponin I, and/or N-terminal pro B-type natriuretic peptide
* Positive serology results for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody, or human immunodeficiency virus (HIV) 1 or 2
* History of coagulopathies, bleeding disorders, blood dyscrasias, hematological malignancies, myelosuppression (including iatrogenic), or current major bleeding event
* Concomitant disease or condition that could interfere with, or treatment of which might interfere with, the conduct of the study, or what would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study
* Confirmed clinically significant abnormality in parameters of hematology
* Confirmed clinically significant abnormality in parameters of clinical chemistry, coagulation, or urinalysis
* Medical history of malignancy, if not considered cured
D: Inclusion Criteria:

* The patient meets current DSM-IV-TR diagnostic criteria for Autistic Disorder (defined in DSM-IV-TR) and also demonstrates behaviors such as tantrums, aggression, self-injurious behavior, or a combination of these problems.
