Introduction: Efficacy and safety of esketamine (ESK) nasal spray were evaluated in ASPIRE-2 (NCT03097133), one of two phase-3 studies in the first global registration program in an understudied population of patients with major depressive disorder (MDD) at imminent risk for suicide.

Methods: In this double-blind (DB), multicenter study, patients (18-64 years) with MDD (DSM-5 criteria), active suicidal ideation with intent, and requiring psychiatric hospitalization were eligible. Patients were randomized (1:1) to ESK (84 mg) or placebo nasal spray twice-weekly along with comprehensive standard-of-care (SoC) for 4 weeks. Efficacy: change from baseline to 24-hours after 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). Safety was monitored.

Results: Of 230 randomized patients, 227 (mean age: 40.8 years) received either ESK+SoC (n=114) or placebo+SoC (n=113); 184/230 (80%) completed DB treatment. Baseline mean MADRS total score was 39.7 and 91% of patients were moderately-extremely suicidal (CGI-SS-R). Patients receiving ESK+SoC showed significant improvement in MADRS total score over placebo+SoC at 24-hours after first dose (LS-mean [SE] difference: −3.9 [1.39]; p=0.006). Although improvement in CGI-SS-R was observed in both treatment groups, between group difference was not significant. During the double-blind phase the most common adverse events in the ESK+SoC group were dizziness (41%), dissociation (39%), nausea (33%) and dysgeusia (25%).

Conclusions: ESK+SoC showed rapid reduction in depressive symptoms in vulnerable MDD patients who have active suicidal ideation with intent. Safety profile was consistent with earlier ESK studies.
