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

Primary Outcome Measures :
- Percentage of Patients Relapsing by Week 16 [ Time Frame: From end of Phase 1 (Date of randomization) to Week 16 of Phase 2 and end of treatment ]Time of relapse=date when patient meets relapse criteria. There are 4 definitions for relapse: 1. Patient meets the following criteria for 2 consecutive visits: (a) Aberrant Behavior Checklist Irritability score ≥25% than score at end of Phase 1 AND (b) Clinical Global Impression Improvement scale rating of 'Much Worse' or 'Very Much Worse' relative to rating at end of Phase 1. If relapse criteria met at 1 visit, 2nd visit should occur in about 1 week to reevaluate whether relapse criteria are still met. 2. Patient discontinues for "Lost to Follow-up" after a visit in which he or she met Definition 1 criteria (a&b). 3. Patient begins a prohibited drug (whether a study investigator or outside source prescribed) to treat worsening symptoms of irritability of autistic disorder after a visit where patient met Definition 1 criteria (a&b). 4. Patient discontinues due to hospitalization for worsening symptoms of irritability or due to lack of efficacy based on investigator's assessment.
Secondary Outcome Measures :
- Adjusted Mean Change From Baseline to Week 16 on the Aberrant Behavior Checklist Irritability (ABC-I) Subscale Score (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline (end of Phase 1) to Week 16 of Phase 2 ]ABC is an informant-based checklist used to assess and classify problem behaviors of children and adolescents with mental retardation. The 58 items are rated on a 4-point scale (0=not at all a problem to 3=the problem is severe in degree), and resolve into 5 subscales: 1) irritability, agitation; 2) lethargy, social withdrawal; 3) stereotypic behavior; 4) hyperactivity, noncompliance; and 5) inappropriate speech. The ABC can be completed by parents, special educators, psychologists, direct caregivers, nurses, and others knowing the participant. Psychometric assessment of the ABC indicates that its subscales have high internal consistency, adequate reliability, and established validity. The ABC-I Subscale Score ranges from 0 to 45, with a negative change in score signifying improvement. LOCF data set includes data recorded at a given visit or, if no observation was recorded at that visit, data carried forward from the prior visit. chg=change; BL=baseline; APR=aripiprazole; vs=versus.
- Change From Baseline in Mean Clinical Global Impression Improvement (CGI-I) Scale Score at Week 16 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline (end of Phase 1) to Week 16 of Phase 2 ]CG-I rating scale permits global evaluation of patient's improvement over time. At baseline (BL), CGI Severity of Illness assessment is performed, in which the clinician rates severity of patient's condition on a 7-point scale ranging from 1=no symptoms to 7=very severe symptoms. Higher total score=worse symptoms. At subsequent visits, clinician assesses patient's improvement relative to symptoms at baseline on CGI-I 7-point scale ranging from 1=very much improved to 7=very much worse. Since the drug targets irritability symptoms, the CGI focuses on severity of irritability secondary to autistic disorder. Lower score=more improved symptoms. LOCF data set includes data recorded at a given visit or, if nothing recorded, data areccarried forward from the prior visit. For secondary endpoints (endpt), hierarchical testing was used to keep overall experiment-wise type I error rate to <=0.05. diff=difference; IS=irritability scale; PA=primary analysis; signif=significance/significantly.
- Number of Participants With Death as Outcome, Serious Adverse Events (SAEs), and Adverse Events (AEs) Leading to Discontinuation During Phase 1 [ Time Frame: Weekly from Week 1 to Week 26 and continuously to end of treatment ]AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization.
Other Outcome Measures:
- Number of Participants With Death as Outcome, Serious Adverse Events (SAEs), Adverse Events (AEs) Leading to Discontinuation, and Treatment-related AEs During Phase 2 [ Time Frame: Weekly from Weeks 1 through 16 (end of treatment) of Phase 2 ]AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug.
