A Long-term Comparison of Esketamine Nasal Spray Versus Quetiapine Extended Release, Both in Combination With a Selective Serotonin Reuptake Inhibitor/Serotonin-Norepinephrine Reuptake Inhibitor, in Participants With Treatment Resistant Major Depressive Disorder

Study Overview
=================
Brief Summary
-----------------
The primary purpose of this study is to evaluate the efficacy of flexibly dosed esketamine nasal spray compared with quetiapine extended-release (XR), both in combination with a continuing selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI), in achieving remission in participants who have treatment-resistant major depressive disorder (MDD) with a current moderate to severe depressive episode.

Detailed Description
-----------------
A depressive state with classical symptoms such as low (depressive/sad) mood, markedly diminished interest in activities, significant weight loss/gain, insomnia or hypersomnia, psychomotor agitation/retardation, excessive fatigue, inappropriate guilt, diminished concentration, and recurrent thoughts of death, persisting for more than 2 weeks is classified as major depressive disorder (MDD). The mechanism of action of ketamine is distinct from conventional antidepressants (ADs), which target the monoamines (serotonin, norepinephrine, and/or dopamine). Esketamine, the S-enantiomer of ketamine, is approved and widely used for the induction and maintenance of anesthesia via intramuscular or intravenous (IV) administration. There is a significant unmet need to develop novel AD treatments based on the relevant psychophysiological pathways underlying MDD. The goal of any novel treatment would be the rapid and long-lasting relief of depressive symptoms, especially in participants with treatment-resistant depression (TRD), who lack a sufficient response to the currently available treatment strategies. The study consists of a Screening Phase (up to 14 days), an Acute Phase (8 Weeks), a Maintenance Phase (24 Weeks) and a Safety Follow-up Phase (2 Weeks). Safety assessment includes adverse event, serious adverse events, physical examination, vital signs, electrocardiogram, clinical safety laboratory assessments, suicidal risk monitoring. The total duration of the study is approximately 36 Weeks for all participants.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Remission as Assessed by the Montgomery-Asberg Depression Rating Scale (MADRS) Score at Week 8 | Percentage of participants with remission as assessed by the MADRS at Week 8 was reported. The MADRS is a clinician-rated scale designed to measure depression severity and to detect changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition. The MADRS evaluates apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts. A participant was defined as being in remission if the MADRS total score was less than or equal to (<=)10 and no treatment or study discontinuation before Week 8. | Week 8 | 

Secondary Outcome Measures

The WPAI-D questionnaire is a validated short instrument that assesses impairment in work and other regular activities over the past 7 days. The WPAI yields four types of scores: (a) Absenteeism (work time missed); (b) Presenteeism (impairment at work / reduced on-the-job effectiveness); (c) Work productivity loss (overall work impairment / absenteeism plus presenteeism); (d) Activity Impairment. The first three scores were derived only for respondents who were working (should be missing for non-working), but the last score was applicable for all respondents. Each score ranges from 0 to 100 with higher scores indicating greater impairment and less productivity. LOCF is defined as the participants who had a missing value or who stopped treatment at a specific time point had their last non-missing value carried forward. | Baseline, LOCF at Weeks 4, 8, 12, 16, 20, 24, 28, 32 | 
| Number of Participants With Treatment-emergent Adverse Events (TEAEs) | An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/ biological agent under study. TEAEs were those events if they started after administration of the first dose until 14 days after the last dose of study medication for other TEAEs except serious; and first dose until 30 days after the last dose of study medication for serious TEAEs. | Up to Week 35 | 
| Number of Participants With TEAEs of Special Interest | Number of participants with TEAEs of special interest were reported. It included significant TEAEs that were judged to be of special interest because of clinical importance, known or suspected class effects, or based on nonclinical signals. Events such as sedation, depersonalization/derealization disorder, depression suicidal, aggression, allergic cystitis, cholestasis and jaundice of hepatic origin, and many more were considered as TEAEs of special interest. | Up to Week 35 | 
| Number of Participants With Suicidal Ideation or Behavior as Assessed by Columbia-Suicide Severity Rating Scale (C-SSRS) Score | Number of participants with suicidal ideation or behavior as assessed by C-SSRS score was reported. The C-SSRS is an assessment tool that evaluates suicidal ideation and behavior. Suicidal ideation consists of 5 items: wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods (not plan) without intention to act, active suicidal ideation with some intent to act without specific plan, and active suicidal ideation with specific plan and intent. Suicidal behavior consists of 5 items: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt (non-fatal), and completed suicide. The maximum score (from the 10 categories) assigned for each participant was summarized into one of three broad categories: No suicidal ideation or behavior (0), Suicidal ideation (1 - 5), Suicidal behavior (6 - 10). Total score ranges from 1 to 10. Higher scores indicate more severe suicidal ideation and behavior. | Weeks 1, 2, 3, 4, 8, 12, 16, 20, 24, 28, 32 |
