Primary Outcome Measures:
  • Number of Participants With Serious Adverse Events (SAEs), Treatment-Emergent Adverse Events (AEs), Deaths, AEs Leading to Discontinuation, Extra Pyramidal Syndrome (EPS)-Related AEs [ Time Frame: From Screening (up to 42 days prior to treatment start) through Week 52 (end of study) for SAEs; from Week 0 (Baseline) through Week 52 (End of Study) for AEs ] [ Designated as safety issue: Yes ]
    Participants with Adverse Events (AEs), Deaths, Serious AEs (SAEs), and AEs leading to study discontinuation. AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition. SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a cancer, is a congenital anomaly/birth defect, results in the development of drug dependency or drug abuse, is an important medical event.

  • Mean Change From Baseline in Total Simpson-Angus Scale (SAS) At Week 8, Week 26, and Week 52 [ Time Frame: Baseline, Week 8, Week 26, Week 52 ] [ Designated as safety issue: Yes ]
    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 52 [ Time Frame: Baseline, Week 8, Week 26, Week 52 ] [ Designated as safety issue: Yes ]
    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.

    The Barnes Akathisia Rating Scale is a 4-item scale to assess presence and severity of drug-induced akathisia, including both objective items and subjective items, together with a global clinical assessment of akathisia. Global assessment is made on a scale of 0 to 5 with comprehensive definitions provided for each anchor point on scale: 0=absent; 1=questionable; 2=mild akathisia; 3=moderate akathisia; 4=marked akathisia; 5=severe akathisia. Score has a possible range from 0 (absent) to 5 (severe akathisia). Negative change scores indicate improvement in akathisia.

    These abbreviations are used in the table of ECG measurements: supraventricular (SV), baseline (BL), 1 degree (1°), atrioventricular (A-V), intraventricular (IVT), symmetrical (SYM), corrected QT interval (QTc). 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).

    CY-BOCS is a 10-item, clinician-rated scale designed to measure the severity of obsessive-compulsive symptoms in patients below the age of 18. The scale contains 5 items pertaining to obsessions (which were not used in this trial) and 5 items pertaining to compulsions, which rated each symptom domain in terms of time spent, interference with functioning, distress, resistance, and control. Each item was rated on a 5-point scale, from 0 (no symptoms or minimum severity) to 4 (extreme symptoms or maximum severity). CY-BOCS Score is from 0 to 20. A negative change score signifies improvement.
