Introduction: ASPIRE-1 is one of two global phase-3 studies in the registration program to evaluate efficacy and safety of esketamine nasal spray (ESK) vs placebo, with comprehensive standard-of-care (SoC), in patients with major depressive disorder (MDD) at imminent risk for suicide.

Methods: In this double-blind (DB), placebo-controlled study (NCT03039192), patients (aged 18-64 years) with moderate to severe MDD (DSM-5 criteria) who had active suicidal ideation with intent, and required psychiatric hospitalization, were enrolled. Patients were randomized (1:1) to ESK 84-mg or placebo twice-weekly along with comprehensive SoC antidepressants for 4 weeks. Change from baseline to 24-hours post first dose in Montgomery-Ǻsberg Depression Rating Scale (MADRS) total score (primary endpoint) and Clinical Global Impression–Severity of Suicidality–Revised (CGI-SS-R) (key secondary endpoint) were evaluated. Safety assessments were performed.

Results: 225 of 226 randomized patients (mean age: 39.3 years) received placebo+SoC (n=112) or ESK+SoC (n=113); 195/226 (86%) completed DB-phase. At baseline, mean MADRS score was 41.1, and 89% were moderately to extremely suicidal (CGI-SS-R). Patients receiving ESK+SoC showed significant improvement in MADRS total score vs placebo+SoC (LS-mean [SE] difference: -3.8 [1.39]; p=0.006) at 24-hours after first dose. Although improvement in CGI-SS-R was observed in both treatment groups, the between group difference was not significant. Most common treatment-emergent adverse events observed in ESK+SoC were dizziness (35%), dissociation (29%), and nausea (20%).

Conclusion: ESK+SoC treatment was efficacious in rapidly reducing depressive symptoms in MDD patients at imminent risk for suicide. Safety findings were consistent with the established safety profile of ESK.
