Brief Summary:
The purpose of this study is to assess the efficacy and dose response of intranasal esketamine (Panel A: 28 mg, 56 mg, and 84 mg and Panel B: 14 mg and 56 mg) compared with placebo in improving depressive symptoms in participants with treatment-resistant depression (TRD).

Condition or disease Intervention/treatment Phase
Treatment Resistant Depressive Disorder Drug: Esketamine 14 mg Drug: Esketamine 28 mg Drug: Esketamine 56 mg Drug: Esketamine 84 mg Drug: Placebo Phase 2

Detailed Description:
This will be a 2-panel, randomized ( participants are assigned different treatments based on chance), double-blind (neither investigator nor participant knows which treatment the participant receives), placebo-controlled (placebo is an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial), multicenter study. Approximately 100 male and female adult participants diagnosed with TRD will participate in this study. For participants in both panels (Panel A and Panel B), there will be 4 study phases: a 4-week screening phase, a double-blind treatment phase (Day 1 to Day 15), an optional open-label treatment phase (Panel A: Day 15 to 74; Panel B: Day 15 to 25), and an 8-week post-treatment (follow-up) phase. Depending on the treatment Panel, patients will be assigned to intranasal placebo or intranasal esketamine 14 mg, 28 mg, 56 mg, or 84 mg. Safety assessments will be performed throughout the study. The maximum study duration for a participant will be 23 weeks for Panel A and 16 weeks for Panel B.

Primary Outcome Measures :
  1. Panel A and B: Change From Baseline (Day 1) in Montgomery Asberg Depression Rating Scale (MADRS) Total Score at Day 8- Analysis of Covariance (ANCOVA) Analysis [ Time Frame: Baseline (Day 1) and Endpoint (Day 8) of Period 1 ]
    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. A negative change in score indicates improvement.

Participants respond to each item using a 4-point scale with response categories of 0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day. Item responses are summed to yield a total score with a range of 0 to 21, where higher scores indicate more anxiety. The recall period is 2 weeks. The severity of the GAD-7 is categorized as follows: None (0-4), Mild (5-9), Moderate (10-14) and Severe (15 -21).

    PGI-S is a patient-rated scale that assesses the severity of their illness at the time of assessment, relative to participants past experience. It is a 4-point (1 to 4) scale in response to the question 'Considering all aspects of your depression right now would you say your depression is?' with scores as follows: 1: none; 2: mild; 3: moderate; 4: severe. A higher score implies a more severe condition.
