Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Double-Blind (DB) Induction Phase: Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Day 28	MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. Negative change in score indicates improvement.	Baseline (Day 1) up to Day 28 (DB phase) induction
Secondary	DB Induction Phase: Percentage of Participants With Response Based on MADRS Total Score	A participant is defined as responder (yes=1 and no=0) at a given time point if the percent improvement from baseline in MADRS is greater than or equal to (>=) 50 percent (%). MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Days 2, 8, 15, 22 and 28 (DB induction phase)
Secondary	DB Induction Phase: Percentage of Participants With Remission Based on MADRS Total Score	A participant was considered in remission at a given time point if the MADRS total score <=12. MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Days 2, 8, 15, 22 and 28 (DB induction phase)
Secondary	DB Induction Phase: Percentage of Participants Showing Onset of Clinical Response	A participant was defined as having a clinical response if there was at least 50% improvement from baseline in the MADRS total score with onset by Day 2 that was maintained to Day 28 in DB induction phase. Participants were allowed one excursion (non-response) on Days 8, 15 or 22, provided the score is at least 25% improvement. MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Day 2 up to Day 28 (DB induction phase)
Secondary	DB Induction Phase: Change From Baseline in Clinical Global Impression - Severity (CGI-S) Total Score up to Day 28	CGI-S provides measure of severity of participant's illness including participant's history, psychosocial circumstances, symptoms, behavior and impact of symptoms on ability to function. CGI-S evaluates severity of psychopathology on scale of 0 to 7. Considering total clinical experience, participant is assessed on severity of mental illness according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among most extremely ill patients. Values of 0 (not assessed) were excluded from analysis. CGI-S permits global evaluation of participant's condition at given time.	Baseline (Day 1) up to Day 28 (DB induction pahse)
Secondary	DB Induction Phase: Change From Baseline in Generalized Anxiety Disorder 7-Item Scale (GAD-7) up to Day 28	GAD-7 was a brief and validated 7-item self-report assessment of overall anxiety. Participants respond to each item using a 4-point scale with response categories of 0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day. Item responses are summed to yield a total score with a range of 0 to 21, where higher scores indicate more anxiety. The recall period is 2 weeks. The severity of the GAD-7 is categorized as follows: None (0-4), Mild (5-9), Moderate (10-14) and Severe (15 -21).	Baseline (Day 1) up to Day 28 (DB induction phase)
Secondary	DB Induction Phase: Change From Baseline in Sheehan Disability Scale (SDS) Total Score up to Day 28	SDS is a participant-reported outcome measure and 5 item questionnaire used for assessment of functional impairment and associated disability. First three items assess disruption of 1 work/school, 2 social life, 3 family life/home responsibilities using a 0(no impairment)-10 (most severe impairment). Score for first 3 items are summed to create total score of 0-30 where higher score indicates greater impairment and a negative change in score indicates improvement. It also has one item on days lost from school or work and one item on days when under productive.	Baseline (Day 1) to Day 28 (DB induction phase)
Secondary	Posttreatment Phase: Time to Relapse in Participants With Remission (MADRS Total Score <=12)	Time to relapse in participants with remission at the end of the double-blind phase was defined as the time between induction phase and the first documentation of a relapse event during the posttreatment phase. Relapse was defined as any of the following: 1) MADRS total score >= 22 for 2 consecutive assessments. The date of the second MADRS assessment was used for the date of relapse; 2) Hospitalization for worsening depression or any other clinically relevant event determined per clinical judgment to be suggestive of relapse of depressive illness like suicide attempt, completed suicide, or hospitalization for suicide prevention. If hospitalized for any of these events, start date of hospitalization was used as relapse date. If participant was not hospitalized, event date was used. 3) If both relapse criteria were met, earlier date was defined as date of relapse. Remission was defined as MADRS total score <=12.	From EndPoint (last post baseline assessment value during the DB induction phase [up to Day 28]) up to 24 weeks (posttreatment phase)
Secondary	Posttreatment Phase: Time to Relapse in Participants With Response (>=50% Reduction From Baseline in MADRS Total Score) But Who Are Not in Remission	Time to relapse in participants with response (>=50% reduction from baseline in MADRS total score) but who are not in remission was reported. Relapse is defined as any of the following: 1) MADRS total score >= 22 for 2 consecutive assessments. The date of the second MADRS assessment was used for the date of relapse. 2)Hospitalization for worsening depression or any other clinically relevant event determined per clinical judgment to be suggestive of relapse of depressive illness like suicide attempt, completed suicide, or hospitalization for suicide prevention. If hospitalized for any of these events, start date of hospitalization was used as relapse date. If participant was not hospitalized, event date was used. 3) If both relapse criteria were met, earlier date was defined as date of relapse. Remission was defined as MADRS total score <=12.	From EndPoint (last post baseline assessment value during the DB induction phase [up to Day 28]) up to 24 weeks (posttreatment phase)
Secondary	Posttreatment Phase: Change From Baseline in Sheehan Disability Scale (SDS) Total Score at Weeks 2, 4, 6, 8, 12, 16, 20 and 24	SDS is a participant-reported outcome measure and is a 5-item questionnaire which has been widely used and accepted for assessment of functional impairment and associated disability. The first three items assess disruption of (1) work/school, (2) social life, and (3) family life/home responsibilities using a 0-10 rating scale. The score for the first three items are summed to create a total score of 0-30, where a higher score indicates greater impairment. It also has one item on days lost from school or work and one item on days when under productive. FAS (responders): All randomized participants who received at least 1 dose of intranasal study medication during DB induction phase and who were responders at the end of DB induction phase and entered posttreatment phase	Baseline (DB induction phase), Weeks 2, 4, 6, 8, 12, 16, 20 and 24 (posttreatment phase)
Secondary	OL Induction Phase: Percentage of Participants With Remission Based on MADRS Total Score	A participant was considered in remission at a given time point if the MADRS total score <=12. MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Days 8, 15, 22 and 28 (OL induction phase)
Secondary	OL Induction Phase: Change From Baseline (Prior to the First Dose of OL Induction Phase) in MADRS Total Score up to Endpoint OL Induction Phase (Last Post Baseline Assessment Value During the OL Induction Phase [OL: up to Day 28])	MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition.	Baseline (Prior to first Dose of OL induction phase on Day 1) up to endpoint of OL induction phase (last post baseline assessment value during OL induction phase [OL: up to Day 28])
Secondary	OL Induction Phase: Percentage of Participants With Severity of Psychopathology on the CGI-S Scale	CGI-S provides measure of severity of participant's illness including participant's history, psychosocial circumstances, symptoms, behavior and impact of symptoms on ability to function. CGI-S evaluates severity of psychopathology on scale of 0 to 7. Considering total clinical experience, participant is assessed on severity of mental illness according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among most extremely ill patients.
