This is an interventional treatment trial for Depressive Disorder, Treatment-Resistant
Eligibility Criteria
Inclusion Criteria:

- At screening, participants must have had a documented nonresponse to at least 2 but not more than 6 oral antidepressants (AD) treatments taken at adequate dosage and for adequate duration within the current episode of depression evaluated retrospectively. Nonresponse documentation at screening must include the sequence of retrospectively failed antidepressants and combination and or augmentation for retrospectively failed antidepressants
- Must be medically stable based on physical examination, medical history, vital signs (including blood pressure). If there are any abnormalities that are not specified in the inclusion and exclusion criteria, their clinical significance must be determined by the investigator and recorded in the participant's source documents
- Must be comfortable with self-administration of nasal medication and be able to follow the nasal administration instructions provided
- A woman of childbearing potential must have a negative highly sensitive serum (Beta human chorionic gonadotropin [Beta hCG]) at screening and a negative urine pregnancy test prior to the first dose of study intervention on Day 1 of the induction phase prior to randomization
Exclusion Criteria:
- Depressive symptoms that have previously not responded to any of the following:
a Esketamine or ketamine in a major depressive episode per clinical judgment, or b All of the classes of oral ADs in the study or an adequate AD augmentation/combination therapy in the current major depressive episode, or c An adequate course of treatment with electroconvulsive therapy in the current major depressive episode, defined as at least 7 treatments with unilateral/bilateral electroconvulsive therapy
- Received vagal nerve stimulation (VNS) or has received deep brain stimulation (DBS) in the current episode of depression
- Has a current or prior DSM-5 diagnosis of a psychotic disorder or MDD with psychotic features, bipolar or related disorders (confirmed by the MINI), intellectual disability, autism spectrum disorder, borderline personality disorder, antisocial personality disorder
- Has homicidal ideation or intent, per the investigator's clinical judgment; or has suicidal ideation with some intent to act within 1 month prior to screening, per the investigator's clinical judgment; or based on the Columbia Suicide Severity Rating Scale (C-SSRS), corresponding to a response of "Yes" on Item 4 (active suicidal ideation with some intent to act, without specific plan) or Item 5 (active suicidal ideation with specific plan and intent) for suicidal ideation on the C SSRS, or a history of suicidal behavior within the past year prior to screening. Participants reporting suicidal ideation with intent to act or suicidal behavior prior to the start of the induction phase should also be excluded
- History of moderate or severe substance use disorder or severe alcohol use disorder according to DSM-5 criteria, except nicotine or caffeine, within 6 months before the start of the screening or current clinical signs
- Has other inflammatory diseases that might confound the evaluations of benefit of guselkumab therapy, including but not limited to Rheumatoid arthritis (RA), axial spondyloarthritis (this does not include a primary diagnosis of psoriatic spondylitis [PsA] with spondylitis), systemic lupus erythematosus, or Lyme disease

Active Comparator
Esketamine + Oral Antidepressants
Placebo + Oral Antidepressants
Participants will receive esketamine as nasal spray (28 milligram [mg] [initial dose for elderly participants 65-74 years of age] on Day 1 and then uptitrated to 56 mg on Day 4, 56 mg [initial dose for adult participants aged 18-64 years and may be used for all age groups throughout the study] or 84 mg [maximum uptitrated esketamine dose]) twice-weekly with a flexible dose regimen from Day 1 until Day 28 (Week 4), once weekly from Week 5 to Week 8 and once-weekly or once every other week from Week 9 to Week 32. The dose may be increased/decreased at any visit or may remain the same as determined by the investigator based on efficacy and tolerability. In addition, participants will initiate a new standard-of-care oral anti depressants (AD) (escitalopram, sertraline, duloxetine, agomelatine, mirtazapine, bupropion or trazodone prolonged release) on Day 1, taken daily for the duration of the study.
