Change from baseline in the CDRS total score were reported. The CDRS-R was a validated 17-item, clinician-rated instrument that measured the severity of a subject's depressive symptoms. The CDRS-R total score was the sum of the responses to 17 questions, ranged from 17 to 113. Each scale item was scored from 1 to 5 or 1 to 7. The highest possible score is 113 (the most severe measure of depression), and the lowest is 17 (not suffering from depression). Higher scores represent a more severe condition. Safety analysis set included all randomised subjects who took at least 1 dose of study intervention.

Each item scored from 0 (no symptoms or normal) to 6 (symptoms of maximum severity), & the sum of scores of individual question items at a given time point ranged from 0 to 60. Higher scores indicated more severe condition. Safety analysis set included all randomised subjects who took at least 1 dose of study intervention.

Change from Baseline in Clinical Global Impression- severity (CGI-S) Score Over Time | |||||||||||||||||||||
End point description |
Change from baseline in the CGI-S score were reported. The CGI-S provided an overall clinician-determined summary measure of the severity of the subject's illness. The CGI scale is an investigator-rated evaluation that assesses the severity of a subject's illness on a 7-point scale, ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill subjects). Considering total clinical experience with the depression population, a subject was assessed on severity of illness at the time of rating according to: 1=normal (not at all ill); 2=borderline ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill subjects. Higher scores indicated more severe condition. Safety analysis set included all randomised subjects who took at least 1 dose of study intervention.

Change from Baseline in Subjective Sleep Assessment (Patient Reported Outcome Measurement Information System-Pediatric-Sleep Disturbance [PROMIS-Pediatric-SD] | ||||||||||||
End point description |
The PROMIS-Pediatric-SD was a static 8 item questionnaire used to assess self-reported perceptions of sleep quality. Each item has 5 responses scored on a 5 level Likert-type scale. The 8-item short form were used, in which responses were scored 1 to 5 for each item. For the 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. Lower scores indicate less sleep disturbance The “direction” of the responses was not the same for all questions, i.e., sometimes a response of “always” indicated more sleep disturbance and sometimes a response of “always” indicated less sleep disturbance. Safety analysis set included all randomised subjects who took at least 1 dose of study intervention. Here "N" (Number of subjects analysed) signifies the number of subjects that were evaluable for this endpoint.

Full analysis set included all randomised subjects who took at least 1 dose of study intervention. Here "N" (Number of subjects analysed) signifies the number of subjects that were evaluable for this endpoint and "n"(number of subjects analysed) signifies number of subjects analysed at specified timepoints.

Change from Baseline on Objective Sleep Assessment Actigraphy: Wake After Sleep Onset | ||||||||||||||||||||||||||||||
End point description |
Change from baseline on objective sleep assessment actigraphy: Wake after sleep onset was reported. Objective sleep parameters were measured using actigraphy. Wake after sleep onset was the number of epochs of the given sleep interval scored as wake by the actigraphy software, in minutes. Full analysis set included all randomised subjects who took at least 1 dose of study intervention. Here "N" (Number of subjects analysed) signifies the number of subjects that were evaluable for this endpoint and "n"(number of subjects analysed) signifies number of subjects analysed at specified timepoints.

Change From Baseline in Subjective Sleep Related Impairment (PROMIS-Pediatric- Sleep-Related Impairment [SRI]) | ||||||||||||
End point description |
Change from baseline in PROMIS-Pediatric-SRI were reported. The PROMIS-SRI 8 items score was used to assess self-reported daytime perceptions of alertness, sleepiness, and tiredness during usual waking hours, and the perceived functional impairments during wakefulness associated with sleep problems or impaired alertness and assessed on a 5 level Likert-type scale. The 8-item short form used in this study, scored 1 to 5 for each item. For the 8-item form, the lowest possible raw score is 8; the highest possible raw score is 39. Total raw score for a short form with all questions answered equals sum of the values of response to each question. Higher overall score indicated more sleep disturbance. Safety analysis set included all randomised subjects who took at least 1 dose of study intervention. Here "N" (Number of subjects analysed) signifies the number of subjects that were evaluable for this endpoint.

| Notes [11] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period. Justification: Data for this endpoint was planned to be collected and analysed only for the arm "Seltorexant 10 mg and 20 mg. |

Date |
Amendment |

27 Mar 2023 |
The purpose of the protocol amendment dated 27-Mar-2023 was to align the protocol criteria more with current clinical practices and to increase feasibility of the study conduct. Due to subject feedback to sites regarding length and number of visits, adjustments were made to the visits as noted in the protocol amendment to allow for visit flexibility through remote assessment. |
