Outcome Measures
Primary Outcomes (11)
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)
An adverse event is any untoward medical occurrence in a clinical study participants who administered a medicinal (investigational or non-investigational) product and does not necessarily have a causal relationship with the treatment. A TEAE defined as an event that was new in onset or increased in severity following treatment initiation.
Up to End of Follow up Phase (Week 56)
Percentage of Participants With Cystitis, Urinary Tract Infections, Renal and Urinary Tract Symptoms, Renal and Urinary Disorders
Percentage of participants with cystitis, urinary tract infections, renal and urinary tract symptoms, renal and urinary disorders were evaluated. Cystitis and urinary tract infections are selected MedDRA preferred terms, "renal and urinary tract symptoms" refers to any preferred term (PT) in the group of selected PTs; and "renal and urinary disorders" refers to a MedDRA System Organ Class (SOC).
Up to End of Follow up Phase (Week 56)
Change From Baseline in Cognitive Test Battery: Detection Test (DET) Score
This battery is a series of computerized cognition tests (detection, identification, one card learning, one back and groton maze learning) designed to measure reaction time, visual learning and memory, and executive function/sequencing. The DET is a measure of psychomotor function and uses a well-validated simple reaction time. In this outcome measure, speed of performance of participants (calculated as mean of the logarithmic base 10 transformed reaction times) for correct responses was reported. Total score ranges from 2 to 3.3 log 10 milliseconds (msec). Lower score indicates better performance. Higher change from baseline indicates better performance.
Baseline (IND) up to the Endpoint (last post-baseline assessment value during 52 weeks of Optimization/Maintenance [OP/MA] Phase)
Change From Baseline in Cognitive Test Battery: Identification Test (IDN) Score
This battery is a series of computerized cognition tests (detection, identification, one card learning, one back and groton maze learning) designed to measure reaction time, visual learning and memory, and executive function/sequencing. IDN test is a measure of visual attention (choice reaction time) and scored for speed of response (mean of the log10 transformed reaction times for correct responses). Total score ranges from 2 to 3.3 log 10 msec. Lower score indicates better performance. Higher change from baseline indicates better performance.
Baseline (IND) up to the Endpoint (last post-baseline assessment value during 52 weeks of OP/MA Phase)
Change From Baseline in Cognitive Test Battery: One Card Learning Test (OCL) Score
This battery is a series of computerized cognition tests (detection, identification, one card learning, one back and groton maze learning) designed to measure reaction time, visual learning and memory, and executive function/sequencing. OCL test is a measure of visual episodic memory and visual recall test scored using arcsine transformation of the percentage of correct responses (CR). The range for OCL is 0 to 100 percent (%) accuracy; presented as an arcsin transformation, the range is 0 to 1.57. Higher score indicates better performance. Higher change from baseline indicates better performance.
Baseline (IND) up to the Endpoint (last post-baseline assessment value during 52 weeks of OP/MA Phase)
Change From Baseline in Cognitive Test Battery: One Back Test (ONB) Score
The ONB is a measure of working memory and scored for speed of correct response (mean of the log10-transformed reaction times for correct responses). Total score ranges from 2 to 3.54 log10 msec. Lower score indicates better performance. Higher change from baseline indicates better performance.
Baseline (IND) up to the Endpoint (last post-baseline assessment value during 52 weeks of OP/MA Phase)
Change From Baseline in Cognitive Test Battery: Groton Maze Learning Test (GMLT) Score
This battery is a series of computerized cognition tests (detection, identification, one card learning, one back and groton maze learning) designed to measure reaction time, visual learning and memory, and executive function/sequencing. GMLT measures executive function; maze/sequencing test, scored for total number of errors. Total score ranges from 0 to 999 number of errors. Lower score indicates better performance. Higher change from baseline indicates better performance.
Baseline (IND) up to the Endpoint (last post-baseline assessment value during 52 weeks of OP/MA Phase)
Change From Baseline in Hopkins Verbal Learning Test-Revised (HVLT-R) Score: Total Recall
Hopkins Verbal Learning Test (HVLT) 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 retention (%) score (0-100%) is calculated by dividing the delayed recall trial by the higher of learning trial 2 or 3; and the recognition discrimination index is comprised by subtracting the total number of false positives from the total number of true positives. A higher score = higher cognition.

Intranasal Esketamine plus oral antidepressant
EXPERIMENTALOpen-Label Induction Phase: Participants will self-administer esketamine intranasally twice per week for 4 weeks as a flexible dose regimen (56 mg or 84 mg). Participants greater than or equal to (\>=) 65 will start at a dose of 28 mg on Day 1. Direct-entry participants will initiate a new, open-label oral antidepressant (duloxetine, escitalopram, sertraline, or venlafaxine extended release \[XR\]) on Day 1; transferred-entry participants will continue the same oral antidepressant from ESKETINTRD3005. Optimization/Maintenance Phase: Participants will self-administer esketamine (56mg or 84mg for those \< 65 years; 28 mg, 56 mg or 84 mg for those \>= 65 years) intranasally once per week for 4 weeks; transferred entry responder subjects from ESKETINTRD3005 will start at a dose of 28 mg in the first week. All participants will continue their same oral antidepressant during this phase.
Interventions
Open-Label Induction Phase: Participants will self-administer esketamine intranasally twice per week for 4 weeks as a flexible dose regimen (56 mg or 84 mg for those \< 65 years; 28 mg, 56 mg or 84 mg for those \>= 65 years). Participants \>= 65 years old will start at a dose of 28 mg on Day 1. Optimization/Maintenance Phase: Participants will self-administer esketamine intranasally (56 mg or 84 mg for those \< 65 years; 28 mg, 56 mg or 84 mg for those \>= 65 years) once weekly then individualized to either once weekly or once every other week based on the severity of depressive symptoms. Transferred-entry responder participants from ESKETINTRD3005 \>= 65 years old will start at a dose of 28 mg in Week 5.
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).
Escitalopram could be selected as the oral antidepressant medication by the investigator based on review of MGH-ATRQ and relevant prior antidepressant medication information. The minimum therapeutic dose is 10 mg/day. Participants \>= 65 years of age will be titrated up to 20 mg/day, but can lower the dose to 10 mg/day for tolerability.
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 up to a dose of 150 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 50 mg/day.
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 for participants \< 65 years of age up to a dose of 225 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 150 mg/day. For participants \>= 65, it can be titrated up to a dose of 150 mg/day, but if not tolerated the dose can be reduced to the minimum therapeutic dose of 75 mg/day.
