Study Arms:
- Intranasal Esketamine plus Oral Antidepressant (Type: EXPERIMENTAL): Participants 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 with first dose (Day 1 as 28 milligram \[mg\]); second dose (Day 4) is either 28 or 56 mg. All subsequent doses may be 28, 56 or 84 mg. After the first dose, all dosing decisions are determined by the investigator based on efficacy and tolerability. 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 (Type: ACTIVE_COMPARATOR): Participants will self-administer matching placebo, intranasally, twice per week for 4 weeks as a flexible dose regimen in Double-Blind Induction Phase using the same titration as Esketamine. In addition participants will simultaneously initiate a new, open-label oral antidepressant (Duloxetine, Escitalopram, Sertraline, or Venlafaxine XR) on Day 1 that will be continued for the duration of Double-Blind Induction Phase.

Based on this trial design, predict the completion outcome and termination type (if applicable).
