Study Arms:
- Intranasal Esketamine 84mg plus Oral Antidepressant (Type: EXPERIMENTAL): As part of an initial titration, participants will self-administer 56 milligrams (mg) of esketamine intranasally on Day 1, and then 84 mg from Day 4 onwards, twice per week for 4 weeks as a fixed dose regimen in Double-Blind Induction Phase. In addition participants will simultaneously initiate a new, open-label oral antidepressant (i.e, duloxetine, escitalopram, sertraline, or venlafaxine extended release \[XR\]) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.
- Esketamine 56 mg plus Oral Antidepressant (Type: EXPERIMENTAL): Starting from Day 1, participants will self-administer 56 mg of esketamine, intranasally, twice per week for 4 weeks as a fixed dose regimen in Double-Blind Induction Phase. In addition participants will simultaneously initiate a new, open-label oral antidepressant (i.e, duloxetine, escitalopram, sertraline, or venlafaxine XR) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.
- Placebo plus Oral Antidepressant (Type: ACTIVE_COMPARATOR): Participants will self-administer matching placebo, intranasally, twice per week for 4 weeks as a fixed dose regimen in Double-Blind Induction Phase. In addition participants will simultaneously initiate a new, open-label oral antidepressant (i.e, duloxetine, escitalopram, sertraline, or venlafaxine XR) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.
