Change From Baseline in Clinician-Rated Children's Global Assessment Score (CGAS) Score

Change from Baseline in Clinician-Rated Children's Global Assessment Score (CGAS) Score for subjects continued from study D1050301 The Children's Global Assessment Scale (CGAS) is a numeric scale (1 through 100) used by mental health clinicians to rate the general functioning of children under the age of 18, where 1 represents the most impaired functioning and 100, superior functioning. Each decile (e.g., 1-10, 11-20) has a descriptive header (e.g., "Moderate impairment in functioning in most domains") and examples of behaviors and types of environmental accommodations that might be seen at that level of functioning. Scores above 70 on the CGAS indicate functioning within the range of typically developing children of the same age as the child being rated while scores below 60 indicate a definite clinical case

Change From Baseline in Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q) Percentage Maximum Possible Score

Change from Baseline in Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q) Percentage Maximum Possible Score for subjects continued from study D1050301 The Pediatric Q-LES-Q is a 15-item self-report measure of the degree of enjoyment and satisfaction in various areas of daily living, based on the content of the Short From of the Q-LES-Q. Each item is rated on a 5-point scale, ranging from 1 (very poor) to 5 (very good). The first 14 items are the same as the General Activities section of the regular Q-LES-Q form and are used to compute the raw score. The PQ-LES-Q-SF percentage maximum possible score is calculated as follows: % Max = 100 × (Raw Score - Minimum Score) / (Maximum Score - Minimum Score), where the Minimum Score equals 14 and the Maximum Score equals 70, and the % maximum possible score can range from 0% to 100%. Higher scores indicate better quality of life.

Change from Baseline in ABC Irritability Subscale Score for subjects continued from study D1050325 The Aberrant Behavior Checklist (ABC) contains 58 items resolve into five subscales: (1) irritability and agitation (15 items), (2) lethargy and social withdrawal (16 items), (3) stereotypic behavior (7 items), (4) hyperactivity and noncompliance (16 items), and (5) inappropriate speech (4 items). Each item is rated for severity on a 4-point Likert scale ranging from 0 (not at all a problem) to 3 (the problem is severe in degree).

In general, higher values of ABC subscale scores represent greater severity of illness. If one or more items are missing, no imputation was performed and the scores of the subscales that include these items was left missing

The ABC contains 58 items resolve into five subscales: (1) irritability and agitation (15 items), (2) lethargy and social withdrawal (16 items), (3) stereotypic behavior (7 items), (4) hyperactivity and noncompliance (16 items), and (5) inappropriate speech (4 items). Stereotypic behavior Subscale Score is calculated as summing of 6, 11, 17, 27, 35, 45, and 49 items . ABC Stereotypic behavior Subscale Score ranges from 0 to 21. Each item is rated for severity on a 4-point Likert scale ranging from 0 (not at all a problem) to 3 (the problem is severe in degree). To score the ABC, the individual items for each subscale are simply summed to their respective totals. It is inappropriate to compute a "total aberrant score", based on a summation of all 58 items, as the subscales are largely independent. In general, higher values of ABC subscale scores represent greater severity

Change From Baseline in Children's Yale-Brown Obsessive Compulsive Score (CY-BOCS)

Change from Baseline in CY-BOCS for subjects continued from study D1050325 CY-BOCS used in the study is a modification of the Yale-Brown Obsessive Compulsive Scale and contains total 7 items for compulsion. "Obsessions" section was removed as it is difficult to obtain valid information given typical language/cognitive delays in the population. Each item of the compulsive scale ranges from 0 to 4. At this time, item 1b ("compulsion-free interval") and item 6 ("peculiarity of the behavior") are not being used in the scoring. Item 7 is a rating for reliability, ranging from 0 (excellent) to 3 (poor). It reflects the interview's judgment regarding the confidence in the data collected hence it is not counted in the CY-BOCS total score. The CY-BOCS compulsion total score is the sums of item 1-5. As a result, the CY-BOCS compulsion total score may range from 0 to 20. In general, higher values of CY-BOCS scores represent greater severity of illness

Change From Baseline in Caregiver Strain Questionnaire (CGSQ) Global Strain Score

Change from Baseline in Caregiver Strain Questionnaire (CGSQ) Global Strain Score for subjects continued from study D1050325 The CGSQ is comprised of total 21 items. Each item is rated on a 5-point Likert-type scale (1 (not at all a problem) to 5 (very much a problem)) and is grouped into three subscales: objective strain, subjective externalized strain, and subjective internalized strain. The 3 subscale scores are calculated as the averages of the corresponding individual items, which range in severity from 1 to 5. Higher scores on each of these subscale scales indicate greater strain. A global strain score is calculated by summing the three subscales (i.e., objective strain, subjective externalized strain, and subjective internalized strain) to provide an indication of the total impact of the special demands on the family. Global strain scores range from 3 to 15. As with the individual subscales, higher scores indicate greater strain

Change from Baseline in CDRS-R Total Score for subjects continued from study D1050326 CDRS-R is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6 17 years. It contains 17 ordinally-scaled items that evaluate the presence and severity of symptoms commonly associated with depression in childhood. The CDRS-R is administered separately to the patient and to the caregiver; among 17 items, 14 items are based on separate interviews with child and parent, 3 items are based solely on the rater's observation of child (ie, no questions).The 14 items are rated on a 1 (no psychopathology) to 7 (most psychopathology) scale, where a rating of 3 represents mild psychopathology. The 3 items (sleep disturbance, appetite disturbance, listless speech) are rated on a 1 (no pathology) to 5 (most pathology) scale. The CDRS-R total score ranges from 17-113. In general, higher values of CDRS-R total score represent greater severity of illness

Change From Baseline in Pediatric Anxiety Rating Scale (PAR) Total Score

Change from Baseline in PAR Total Score for subjects continued from study D1050326 The PARS is a clinician-rated instrument for assessing over time the severity of anxiety symptoms associated with common DSM-IV anxiety disorders in children ages 6 17 years. The PARS is administered separately to the subject and to the caregiver. The instrument has 2 sections. The first section includes a 50-item symptom checklist, which the clinician rates as present or absent during the past week. The second section is comprised of 7 severity impairment items reflecting the severity/impairment of all symptoms endorsed in Section 1 of the PARS (during the past week). Each question is answered on a 0-5 Likert scale (0 for none, and 1-5 for minimal to extreme) with alternative responses of 8=Not Applicable and 9=Does Not Know. Scores of 8 or 9 are not counted in the summation as per the PARS instructions. The PARS total score over all 7 questions ranges in value from 0 to 35.A higher PARS total score

Change from Baseline in Attention-Deficity/Hyperactivity Disorder Rating Scale (ADHD-RS) Total Score for subjects continued from study D1050326 The ADHD-RS IV is a validated scale that measures the behaviors of children with ADHD. The ADHD-RS IV consists of 18 items reflecting current symptomatology of ADHD based on DSM-IV-TR criteria. Each item is scored from a range of 0 (no symptoms) to 3 (severe symptoms) with total scores ranging from 0 to 54. The 18 items may be grouped into two sub-scales: hyperactivity/impulsivity (even number items 2 through 18) and inattentiveness (odd number items 1 through 17), ranging from 0 to 27. A higher ADHD-RS total score and sub-scales scores are associated with greater illness severity
