Title: Safety and Efficacy of Aripiprazole in the Long-term Maintenance Treatment of Pediatric Patients With Irritability Associated With Autistic Disorder
Brief Summary: The purpose of this study is to determine whether pediatric participants with irritability associated with autistic disorder who have responded to aripiprazole treatment will experience a relapse significantly later when continuing therapy with aripiprazole than will participants who receive placebo


Options:
A: Inclusion Criteria:

1. Outpatients 5-17 years of age inclusive.
2. Meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). DSM-5 criteria will be established by a clinician with expertise with individuals with ASD. Diagnosis will be supported by the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2).
3. Complex language to qualify for ADOS-2 modules 3 or 4.
4. If already receiving stable concomitant medications affecting behaviour, have stable regimens with no changes during the preceding 6 weeks prior to Screening, and will not electively initiate new or modify ongoing medications for the duration of the study.
5. If already receiving stable non-pharmacological educational and behavioural interventions, have continuous participation during the preceding 3 months prior to Screening, and will not electively initiate new or modify ongoing interventions for the duration of the study.
6. Have normal physical examination and laboratory test results at Screening. If abnormal, the finding(s) must be deemed clinically insignificant by the Investigator.
7. Ability to obtain written informed consent from the participant, if developmentally appropriate. If a participant does not have the capacity to consent, ability to obtain assent (if developmentally appropriate), as well as written informed consent from their parent(s)/legal guardian(s).

Exclusion Criteria:

1. Pregnant females; sexually active females on inadequate birth control.

Have a serious medical condition that, based on Investigator judgment, might interfere with the conduct of the study, confound interpretation of the study results, or endanger their own well-being. Have evidence of any significant hematological, endocrine, cardiovascular (including uncorrected symptomatic congenital heart disease), respiratory, renal, hepatic, or gastrointestinal disease, not including mild common pediatric diseases in these areas that are stable (e.g. mild asthma, constipation, etc.).

11. Inability to speak and understand English sufficiently enough to allow for the completion of all study assessments (parent/legal guardian; participant).
B: Inclusion Criteria:

1. Male or female outpatients 18 to 60 years of age.
2. Meet Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. The diagnosis will be confirmed with Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule .
3. Have a Clinician's Global Impression-Severity score ≥ 4 (moderately ill) at Screening and Baseline.
4. If already receiving stable nonpharmacologic educational, behavioral, and/or dietary interventions, have continuous participation during the preceding 3 months prior to Screening and will not electively initiate new or modify ongoing interventions for the duration of the study.
5. Have normal physical examination and laboratory test results at Screening. If abnormal, the finding(s) must be deemed clinically insignificant by the Investigators.
6. The patient must be able to speak and understand English sufficiently to understand the nature of the study and to allow for the completion of all study assessments.
7. Have a normal Intelligence Quotient (\>70) supported by the Wechsler Abbreviated Scales of Intelligence.

Exclusion Criteria:

1. Patients born prior to 35 weeks gestational age.
2. Patients with any primary psychiatric diagnosis other than autism at Screening: a history of attention deficit hyperactivity disorder, bipolar disorder, psychosis, posttraumatic stress disorder, schizophrenia, or major depressive disorder.
3. Patients with a medical history of neurological disease, including, but not limited to, epilepsy/seizure disorder (except simple febrile seizures), movement disorder, tuberous sclerosis, fragile X, and any other known genetic syndromes, or known abnormal magnetic resonance imaging/structural lesion of the brain.
4. Pregnant female patients.
5. Patients with a medical condition that might interfere with the conduct of the study, confound interpretation of the study results, or endanger their own well-being. Patients with evidence or history of malignancy or any significant hematological, endocrine, cardiovascular (including any rhythm disorder), respiratory, renal, hepatic, or gastrointestinal disease.
6. Patients taking psychoactive medication(s) (e.g., stimulants, antidepressants, antipsychotics, antiepileptics, anxiolytics, clonidine).
7. Patients who plan to initiate or change nonpharmacologic interventions during the course of the study.
8. Patients unable to tolerate venipuncture procedures for blood sampling.
9. Patients who, in the Investigator's opinion, might not be suitable for the study.
