Esketamine nasal spray (NS) is an established treatment for patients with treatment resistant depression (TRD). To further optimise real-world outcomes, consensus is needed regarding strategies to enhance patient outcomes and decision-making factors for pivotal timepoints in esketamine NS treatment. This modified Delphi panel (3 rounds) established expert consensus (≥80% agreement) from 30...

The INTEGRATE study aimed to provide information on the use, effectiveness, and safety of esketamine nasal spray (ESK-NS) for the treatment of treatment-resistant depression (TRD) in real-world practice in Spain. This was an observational, cross-sectional, retrospective study conducted in adults aged 18-74 years who met the criteria for TRD. The weekly impact of ESK-NS on depressive symptoms...

To assess the effect of esketamine nasal spray on patient-reported outcomes (PROs) in patients with major depressive disorder having active suicidal ideation with intent (MDSI). Patient-level data from two phase 3 studies (ASPIRE I; ASPIRE II) of esketamine + standard of care (SOC) in patients (aged 18-64 years) with MDSI, were pooled. PROs were evaluated from baseline through end of the...

Importance: Controlled studies have shown short-term efficacy of esketamine for treatment-resistant depression (TRD), but long-term effects remain to be established. Objective: To assess the efficacy of esketamine nasal spray plus an oral antidepressant compared with an oral antidepressant plus placebo nasal spray in delaying relapse of depressive symptoms in patients with TRD in stable...

OBJECTIVE: About one-third of patients with depression fail to achieve remission despite treatment with multiple antidepressants. This study compared the efficacy and safety of switching patients with treatment-resistant depression from an ineffective antidepressant to flexibly dosed esketamine nasal spray plus a newly initiated antidepressant or to a newly initiated antidepressant (active...

Ketamine and its enantiomer S-ketamine (esketamine) are promising candidates to produce a rapid-onset antidepressant effect in treatment-resistant depression. Ketamine causes continued blockade of the glutamate N-methyl-D-aspartate (NMDA) receptor, though this might not primarily mediate the antidepressant effect. Alternative hypotheses include selectivity for the NMDA receptor subtype...
