The purpose of this study is to assess the safety and tolerability of esketamine nasal spray in participants with treatment-resistant depression (TRD).
This is an open-label (the researchers and participants know the treatment the participant is receiving) long-term extension study. The study will consist of 2 open-label Phases: 4-week Induction phase (if applicable) and Open-Label Optimization/Maintenance phase (variable). Participants will enter the study Induction Phase from ESKETINTRD3001 (NCT02417064), ESKETINTRD3002 (NCT02418585), ESKETINTRD3003 (NCT02493868), ESKETINTRD3005 (NCT02422186) and ESKETINTRD3006 (US sites only). Participants will enter the study Open-Label Optimization/Maintenance phase from ESKETINTRD3001 (NCT02417064), ESKETINTRD3002 (NCT02418585), ESKETINTRD3003 (NCT02493868) (if appropriate at week 16) or ESKETINTRD3006 (US sites only). In the Open-Label Induction Phase, participants will self-administer flexibly-dosed esketamine nasal spray. During first 4 weeks in Optimization/Maintenance Phase responder participants from the induction phase of study 54135419TRD3008, will continue on the same dose of esketamine nasal spray from the induction phase and have a weekly intranasal treatment session frequency. Participants entering the optimization/maintenance phase from study ESKETINTRD3005 will also have a weekly intranasal treatment session frequency. However, as the ESKETINTRD3005 intranasal study medication is blinded at the time of entry into the current study, the dose of esketamine nasal spray will be administered as outlined in protocol. Participants entering the optimization/maintenance phase from study ESKETINTRD3003 (Direct Entry) or ESKETINTRD3004 who were ongoing in the Optimization, Maintenance, or Optimization/Maintenance phase, respectively, will have the option to have their current intranasal dosing frequency adjusted at the time of entry into 54135419TRD3008 study and should remain on the selected frequency from week 1 to week 4. A one-time dose change will be permitted at study entry. After 4 weeks, esketamine nasal spray treatment sessions will be individualized to either once weekly or once every other week at the fixed 2-week interval (based on clinical global impression - severity \[CGI-S\] performed at that visit), and every 4 weeks for participants dosed at the 4 week interval. Participants safety will be monitored throughout the study.

Change From Study Baseline in Hopkins Verbal Learning Test-Revised (HVLT-R) Score
The HVLT-R measures performance in verbal memory, learning, and long-term recall in which a list of words is read up to three times. Approximately 20-25 minutes later, a delayed recall trial and a recognition trial are completed. The delayed recall requires free recall of any words remembered. The recognition trial is composed of 24 words, including the 12 target words and 12 false-positives. When scoring the HVLT, the three learning trials are combined to calculate a total recall score (0-36); the delayed recall trial creates the delayed recall score (0-12); the total number of true-positive errors (0-12); and the range of recognition discrimination index is comprised by subtracting the total number of false positives from the total number of true positives. A higher total recall score indicated higher cognition. The range of the recognition discrimination index is -12 to 12. Higher score indicated better performance and higher change from baseline indicated better performance.

Change From Baseline in Participant-Reported Depressive Symptoms Using the Patient Health Questionnaire - 9 (PHQ-9) Total Score
Change from baseline in PHQ-9 total score were reported. The PHQ-9 was a 9-item, patient-reported outcome measure to assess depressive symptoms. The scale scores each of the 9 symptom domains of the Diagnostic and Statistical Manual of Mental Disorders. Each item was rated on a 4-point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses were summed to provide a total score (range of 0 to 27) with higher scores indicating greater severity of depressive symptoms.
Time frame: IND Phase: Baseline up to 4 weeks; OP/MA Phase: Baseline up to 78 months
Change From Baseline in Clinical Global Impression-severity (CGI-S) Score
Change from baseline in clinical global impression-severity (CGI-S) score were reported. The CGI-S provides an overall clinician-determined summary measure of the severity of the participant's illness that takes into account all available information, including knowledge of the participant's history, psychosocial circumstances, symptoms, behavior, and the impact of the symptoms on the participant's ability to function. The CGI-S evaluates the severity of psychopathology on a scale of 1 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 1 = normal (not at all ill); 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill participants. Negative change in score indicates improvement.
Time frame: IND Phase: Baseline up to 4 weeks; OP/MA Phase: Baseline up to 78 months

Change From Baseline in Participant-Reported Health-related Quality of Life as Assessed by EuroQol-5 Dimension-5 Level (EQ-5D-5L) Valuation Index Score (VAS)
Change from baseline in participant-reported health-related quality of life as assessed by EQ-5D-5L VAS was reported. The EQ-5D-5L is a standardized 2-part instrument for use as a measure of health outcome, primarily designed for self-completion by respondents. It essentially consists of the EQ-5D-5L descriptive system and the EQ-VAS. EQ-VAS self-rating records the respondent's own assessment of his/her overall health status at time of completion, on a scale of 0 (worst health you can imagine) to 100 (best health you can imagine). Positive change in score indicates improvement.
Time frame: IND Phase: Baseline up to 4 weeks; OP/MA Phase: Baseline up to 78 months
Change From Baseline as Assessed by EQ 5D-5L: Sum Score
EQ-5D-5L consists of EQ-5D-5L descriptive system and EQ visual analogue scale (EQ-VAS). EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "today". Sum score ranges from 0 to 100 where, sum score = (sum of the scores from the 5 dimensions minus 5) \*5. Higher score indicates worst health state.
Time frame: IND Phase: Baseline up to 4 weeks; OP/MA Phase: Baseline up to 78 months
Change From Baseline in Participant- Reported Health Related Quality of Life Using the Quality of Life in Depression Scale (QLDS)
Change from baseline in participant- reported health related quality of life using the QLDS. The QLDS is a disease-specific validated patient-reported outcome (PRO) measure which assesses the impact that depression has on a participant's quality of life. It is a 34-item self-rated questionnaire which consists of dichotomous response questions, with the response being either True/Not True. Each statement on the QLDS is given a score of "1" or "0". A score of "1" is indicative of adverse quality of life. All item scores are summed to give a total score that ranges from 0 (good quality of life) to 34 (very poor quality of life). A higher score indicates a more severe condition.
