Change From Baseline in Children Depression Rating Scale - Revised (CDRS-R) Total Score at Week 8 of Phase B |
The CDRS-R is a clinician-rated scale to measure the severity of depression in children and adolescents. The CDRS-R was rated by a clinician following interviews with the child and parent and consisted of 17 items out of which 3 items rated nonverbal observations (listless speech, hypoactivity, and depressed affect). Fourteen items were rated on a 7-point scale from 1 to 7, and 3 items (sleep disturbance, appetite disturbance, and listless speech) were scored on a 5-point scale from 1 to 5. A rating of 1 indicated normal functioning and a higher number indicated a greater degree of depression. The total score ranged from 17 (normal) to 113 (severe depression). Least square (LS) mean was estimated using a restricted maximum likelihood (REML)-based Mixed Model Repeated Measurements (MMRM) approach. |

Change From Baseline in CDRS-R Subscores (Mood, Somatic, Subjective, and Behaviour) at Weeks 2, 4, 6, and 8 of Phase B |
The CDRS-R was rated by a clinician following interviews with the child and parent and consisted of 17 items out of which 3 items rated nonverbal observations (listless speech, hypoactivity, and depressed affect). Fourteen items were rated on a 7-point scale from 1 to 7, and 3 items (sleep disturbance, appetite disturbance, and listless speech) were scored on a 5-point scale from 1 to 5. A rating of 1 indicated normal functioning and a higher number indicated a greater degree of depression. The total score ranged from 17 (normal) to 113 (severe depression). Four subscores were defined based on the CDRS-R: Mood: sum of items 8, 11, 14, 15; score range 4 to 28, Somatic: sum of items 4, 5, 6, 7, 16, 17; score range 6 to 36, Subjective: sum of items 9, 10, 12, 13; score range 4 to 28, and Behaviour: sum of items 1, 2, 3; score range 3 to 21. Higher scores indicated the most severe measure of depression. |

Change From Baseline in General Behaviour Inventory (GBI) Depression Subscale Score, Using the 10-Item Depression Subscale Assessed by Parent (PGBI-10D) and Child (CGBI-10D) at Weeks 2, 4, 6, and 8 of Phase B |
The GBI 10-item depression scale was developed to screen for depressive symptoms in children and adolescents. Two versions of the GBI 10-item depression scale were used, the child rated version (CGBI) and the parent rated version (PGBI). The 10 depression items were rated on a 4-point scale from 0 (never or hardly ever) to 3 (very often or almost constantly). The total score ranged from 0 to 30, with higher scores indicating greater pathology. |

The clinician uses his or her clinical experience of this participant population to rate the severity of the participant's current mental illness on a 7-point scale ranging from 1 (normal - not at all ill) to 7 (among the most extremely ill participants). |

The CGAS is a clinician-rated global scale to measure the lowest level of functioning for a child (4 to 16 years) during a specified time period. The CGAS contains behaviourally-oriented descriptors at each anchor point that depict behaviours and life situations applicable to a child. The score ranges from 1 (most functionally impaired child) to 100 (the healthiest). A score greater than 70 indicates normal function. |

Change From Baseline in Pediatric Quality of Life Inventory (PedsQL) Visual Analogue Scales (VAS): Afraid or Scared (Anxiety) Score at Weeks 4 and 8 of Phase B |
The PedsQL™ VAS is designed to measure at-that-moment functioning in children and adolescents. The PedsQL VAS consists of 6 domains: anxiety, sadness, anger, worry, fatigue and pain using visual analogue scales. The functionality for each domain is measured on a 10 cm line with a happy face at one end and a sad face at the other (0-10 points). The participants are asked to mark on the line how they feel. A lower value represents a better outcome. |
