All observed or volunteered treatment-emergent AEs and SAEs regardless of treatment group or suspected causal relationship to the investigational product(s) were reported.

Safety Analysis Set = all subjects who took at least one dose of study medication. In this table, the number of subjects with AEs is based on a 0% AE threshold whereas the number of subjects with AEs reported in the AE section are based on a 5% AE threshold.

Tanner Adolescent Pubertal Staging Questionnaire: used to document the stage of development of secondary sexual characteristics. Female pubertal development staged by pubic hair development and breast size; males pubertal development staged by size of the genitalia and development of pubic hair. Rated in 5 stages: stage 1 (no development) to 5 (adult-like development in quantity and size).

Safety Analysis Set. N=number of subjects with analyzable data at baseline. Baseline data from Study A1281134 (NCT00257192) served as the baseline for A1281135.

CPBAQ: 19-item parent or legal guardian completed questionnaire to rate the child's verbal (such as yelling or cursing) and physical aggression (such a fighting with peers or being cruel to an animal) during the past week. Behavior was rated on a 4-point scale; range 0 (behavior did not occur or was not a problem) to 3 (behavior occurred a lot or was severe problem). Total score range 0 to 57; higher scores indicate a greater frequency and severity of aggression.

Safety Analysis Set. N=number of subjects with analyzable data at baseline; n=number of subjects with analyzable data at post-baseline observation.

CDRS-R: clinician-rated interview-based scale (with both child and parent or guardian) to assess 17 distinct symptom areas to derive an index of depression severity. Discrepancies between informants' responses were resolved by using most impaired rating given by valid informant. Rated on a 7-point scale; range from 1 (no impairment) to 7 (indicates greater impairment). Total score calculated as sum of the 17 items (range 1 to 119); higher score indicates greater impairment.

Safety Analysis Set. N=number of subjects with analyzable data at baseline; n=number of subjects with analyzable data at post-baseline observation. Baseline was the last available observation from Study A1281134 (NCT00257192). LOCF imputation used for Week 26 LOCF time point.

Computerized subject-administered test battery with subtests for verbal and visual memory, processing speed, nonverbal reasoning, executive functioning, working memory, sustained attention. Computerized 7- point sedation item (0 [not sleepy] to 10 [very sleepy]) was completed prior to test battery. Neurocognitive index score was derived from subtest scores per an algorithm. Index score and subtest scores assessed the subject's changes in cognition. Scores were rated as above average (score >109), average (90 to 109), below average (80 to 89), or well below average (70 to 79).

SARS: 10-item clinician rated instrument to assess parkinsonian symptoms (7 items) and related extrapyramidal side effects (3 items): gait, arm dropping, shoulder shaking, elbow rigidity, leg pendulousness, glabellar tap, tremor, and salivation. Head dropping (modified SARS item 7) substituted for head rotation. Anchored 5-point scale: range 0 (absence of condition, normal) to 4 (most extreme form of condition). Total score is sum of individual item scores (range 0 to 40); higher score indicates more affected.

BAS: clinician rated scale to assess akathisia to determine the degree of subjective restlessness and distress associated with restlessness. First 3 items (Objective, Subjective, and Distress related to restlessness) rated on a 4-point scale with range 0 (no symptoms) to 3 (increased severity of symptoms). Item 4 Global Clinical Assessment of Akathisia rated on a 6- point scale range 0 (no symptoms) to 5 (increased severity of symptoms); higher score indicates increased severity. All rating are anchored. Only the Global Clinical Assessment of Akathisia was to be analyzed.

AIMS: clinician rated 12-item scale to rate 7 body areas and global judgments on the severity of abnormal movements, incapacitation and subject's awareness of abnormal movements. Items 1 to 10 scored 0 (none) to 4 (severe) (total possible score 0 to 40; higher score indicates greater severity); items 11 to 14 are No or Yes response to dental status and sleep movements. Only the sum of the first 7 items to be analyzed (AIMS Movement Cluster score). Total score 0 to 28; higher score indicates greater severity.

BPRS-A: 18-item clinician rated scale to assess somatic concern, anxiety, emotional withdrawal, disorganization, hallucinatory behavior, guilt feelings, suspiciousness, disorientation, tension, mannerisms, posturing, grandiosity, depressive mood, hostility, motor retardation, uncooperativeness, unusual thought content, blunted affect, excitement. Ratings anchored to improve consistency for single rater over time or between raters. Items rated on 7-point scale 0 (not present) to 6 (extremely severe). Total score=sum of items (range 0 to 108); higher scores indicate increased pathology.

CGAS: clinician-rated global assessment item for children based on symptoms and social functioning in home, school, and community settings. Scores on this single item range from 1 to 100 (higher levels indicate greater health) with descriptive anchors for every 10-point interval. Scores above 70 on this scale are considered within the "normal" range; lower score indicates need for increased supervision.

School placement questionnaire: parent or legal guardian assessed questionnaire to determine whether the child is currently enrolled in school (or planned to be enrolled if on school holiday like summer break), whether attending regularly if enrolled, and how well the child is doing overall in school. Questions were modified from those used in the National Institute of Mental Health (NIMH) funded Treatment of Early Onset Schizophrenia Spectrum (TEOSS) study. Results determine whether subjects are currently attending school and qualitatively describe how well they are doing in school.
