Brief Summary
The purpose of this study is to compare the efficacy and safety of switching treatment-resistant depression (TRD) subjects from a prior antidepressant treatment (to which they have not responded) to either intranasal esketamine plus a new oral antidepressant or switching to a new oral antidepressant plus intranasal placebo.

Outcome Measures
Primary Outcomes (2)
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Day 28 in the Double-blind Induction Phase- Mixed-Effects Model Using Repeated Measures (MMRM) Analysis
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 up to Day 28 of Double-blind Induction Phase
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score up to Endpoint (Double-blind Induction Phase [Day 28])- Analysis of Covariance (ANCOVA) Analysis
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. The last post baseline observation during the phase was carried forward as "End Point" for that phase.

Study Arms (2)
Intranasal Esketamine plus oral antidepressant
EXPERIMENTALParticipants will self-administer esketamine intranasally twice per week for 4 weeks as a flexible dose regimen in the Double-Blind Induction Phase. All participants will start at a dose of 56 mg on Day 1. On Day 4, the dose may be increased to 84 mg or remain at 56 mg per investigator's discretion. On Days 8 and 11 the dose may be increased to 84 mg (from 56 mg), remain same, or be reduced to 56 mg (from 84 mg) per investigator's discretion. On Day 15, a dose reduction from 84 mg to 56 mg is permitted, if required for tolerability; no dose increase permitted. After Day 15, dose must remain stable (unchanged). In addition participants will simultaneously initiate a new, open-label oral antidepressant (duloxetine, escitalopram, sertraline, or venlafaxine extended release \[XR\]) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.
Placebo plus oral antidepressant
ACTIVE COMPARATORParticipants will self-administer matching placebo, intranasally, twice per week for 4 weeks as a flexible dose regimen in Double-Blind Induction Phase. In addition participants will simultaneously initiate a new, open-label oral antidepressant (ie, duloxetine, escitalopram, sertraline, or venlafaxine extended release \[XR\]) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.
Interventions
Participants will self-administer either 56 mg or 84 mg of esketamine, intranasally, twice per week as a flexible dose regimen in the Double-Blind Induction Phase.
Participants will self-administer matching placebo, intranasally, twice per week for 4 weeks as a flexible dose regimen in the Double-Blind Induction Phase.
Duloxetine could be selected as the oral antidepressant medication by the investigator based on review of Massachusetts General Hospital - Antidepressant Treatment Response Questionnaire (MGH-ATRQ) and relevant prior antidepressant medication information. The minimum therapeutic dose is 60 milligram per day (mg/day).
Escitalopram could be selected as the oral antidepressant medication by the investigator based on review of MGH-ATRQ and relevant prior antidepressant medication information. Escitalopram will be titrated upto a dose of 20 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 10 mg/day.
Sertraline could be selected as the oral antidepressant medication by the investigator based on review of MGH-ATRQ and relevant prior antidepressant medication information. Sertraline will be titrated upto a dose of 150 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 50 mg/day.
Venlafaxine Extended Release could be selected as the oral antidepressant medication by the investigator based on review of MGH-ATRQ and relevant prior antidepressant medication information. Venlafaxine Extended Release will be titrated upto a dose of 225 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 150 mg/day.

- Participant has received vagal nerve stimulation (VNS) or has received deep brain stimulation (DBS) in the current episode of depression
- Participant has a current or prior DSM-5 diagnosis of a psychotic disorder or MDD with psychosis, bipolar or related disorders (confirmed by the MINI), comorbid obsessive compulsive disorder, intellectual disability (DSM-5 diagnostic codes 317, 318.0, 318.1, 318.2, 315.8, and 319), borderline personality disorder, antisocial personality disorder, histrionic personality disorder, or narcissistic personality disorder
- Participant has homicidal ideation/intent, per the investigator's clinical judgment, or has suicidal ideation with some intent to act within 6 months prior to the start of the screening/prospective observational phase, per the investigator's clinical judgment or based on the Columbia Suicide Severity Rating Scale (C-SSRS)
