Secondary	Number of Participants With Change in Pubertal Status From Baseline at Week 16	This outcome measure presents "pubertal status results" which is based on Tanner staging recorded at baseline (week 0), week 16. Tanner Stages is a scale that defines physical measurements of development based on external primary and secondary sex characteristics. It was used in this study to assess pubertal development with values ranging from Stage 1 (pre-pubertal characteristics) to Stage 5 (adult or mature characteristics). Results are presented for the following categories: 1) For female: breast development and pubic hair development, 2) For male: penis development and pubic hair development. Each category shows number of participants in stages 1 to 5, where stage 1 represents "early pubertal development" and stage 5 represents "pubertal development equivalent to that of an adult".	Week 0, week 16

These findings were categorised by the investigator. Results include examination of: general appearance; head, ears, eyes, nose, throat, neck; respiratory system; cardiovascular system (CVS); gastrointestinal (GI) system including mouth; musculoskeletal system; central nervous system (CNS) and peripheral nervous system (PNS); skin; thyroid gland and lymph node palpation.

Secondary	Part A: Number of Participants With Change in Columbia Suicidality Severity Rating Scale (C-SSRS) at Week 16	C-SSRS (mapped to Columbia Classification Algorithm of Suicide Assessment [C-CASA]) is an interview-based rating scale to systematically assess suicidality, suicidal behaviour, suicidal ideation. Suicidality: emergence of any suicidal ideation or suicidal behaviour. Suicidal behaviour: when response is "yes" for any of the questions- actual attempt to suicide, engaged in non-suicidal self-injurious behaviour, interrupted attempt, aborted attempt, preparatory acts. Suicidal ideation: when response is "yes" for any of the questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide. This outcome measure presents number of participants with "suicidal ideation or suicidal behaviour on C-SSRS" assessed at baseline (week 0), week 16. The questionnaire was not used in Part B due to the young age of the participants in Part B.	Week 0, week 16

Secondary	Part A: Change in Patient Reported Health Questionnaire-9 (PHQ-9) From Baseline at Week 16	Change in Patient Health Questionnaire 9 (PHQ-9) was evaluated from baseline (week 0) to weeks 16. The PHQ-9 questionnaire is a 9-item depression module included in the patient health questionnaire, a self-administered diagnostic tool used for assessment of mental disorders. The PHQ-9 total score ranges from 0-27; total scores of 1-4 represent no depression, total scores of 5-9 represent mild depression, total scores of 10-14 represent moderate depression, total scores of 15-19 represent moderately severe depression and total scores of 20-27 represent severe depression. The questionnaire was not used in Part B due to the young age of the participants in Part B.	Week 0, week 16
