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.

Conditions

  • Treatment-resistant Depression

Interventions

DRUG

Esketamine

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.

DRUG

Placebo

Participants will self-administer matching placebo, intranasally, twice per week for 4 weeks as a flexible dose regimen in the Double-Blind Induction Phase.

DRUG

Duloxetine (Oral Antidepressant)

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).

DRUG

Escitalopram (Oral antidepressant)

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.

DRUG

Sertraline (Oral Antidepressant)

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.

DRUG

Venlafaxine Extended Release (XR) (Oral Antidepressant)

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.
