De NovoAripiprazoleDe novo participants (those who did not participate in protocol (CN138-178 \[NCT00332241\] or CN138-179 \[NCT00337571\]) assigned to open-label aripiprazole (oral tablet), flexibly dosed (2 to 15 mg/day) taken once daily, started at 2 mg/day on Day 1. Target daily dose was 5 mg, 10 mg, or 15 mg; maximum dose, regardless of weight, was 15 mg. Dose increases were incremental (dose levels are 2 mg, 5 mg, 10 mg, and 15 mg), occurring no more often than every 4 days, and were based on assessment of efficacy and tolerability at the current dose. The dosage could be adjusted downward if the patient experienced intolerance at any time to the current dose.

QRS complex is a recording of a single heartbeat on ECG corresponding to the depolarization of the right and left ventricles. PR interval is measured from beginning of P wave to beginning of QRS complex. QT interval is a measure of time between start of Q wave and end of T wave in the heart's electrical cycle. ↑ = increase from baseline, ↓ = decrease from baseline, → = "to"

The Z-Score indicates how many standard deviations a person is from the population norm values. The body weight z-scores are designed to take into account the amount of weight gain that would be expected due to normal growth in children and adolescents. The body weight z-scores are by age and gender standardized values (corresponding to a normal distribution with mean 0 and a standard deviation of 1) of the actual weight measurements, based on the Growth Charts provided by the Centers for Disease Control (CDC; see Links section of this record).

Mean Change From Baseline in Total Simpson-Angus Scale (SAS) At Week 8, Week 26, and Week 52Baseline, Week 8, Week 26, Week 52

The SAS is a 10-item instrument used to evaluate the presence and severity of parkinsonian symptomatology. It is the most commonly used rating scale for Parkinsonism in clinical trials over the past 25 years. The ten items focus on rigidity rather than bradykinesia, and do not assess subjective rigidity or slowness. Items are rated for severity on a 0-4 scale, with definitions given for each anchor point. The total SAS Score has a possible range from 10 to 50. Negative change scores indicate improvement.

Mean Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) At Week 8, Week 26, and Week 52Baseline, Week 8, Week 26, Week 52

The AIMS is an assessment of movement dysfunctions. It is a 12-item instrument assessing abnormal involuntary movements associated with antipsychotic drugs and 'spontaneous' motor disturbance related to the illness itself. Scoring the AIMS consists of rating the severity of movement in 3 main anatomic areas (facial/oral, extremities, and trunk), based on a five-point scale (0=none, 4=severe). The AIMS Total Score has a possible range from 0 to 28. Negative change scores indicate improvement in movement dysfunction.

Number of Participants With Potentially Clinically Relevant Laboratory Chemistry AbnormalitiesAt screening (up to 42 days prior to treatment start), Week 8, Week 26, Week 52
