This post-hoc analysis evaluated the efficacy and safety of intranasal esketamine in the Asian subgroup from ASPIRE I. Patients with major depressive disorder and suicidal ideation with intent received intranasal esketamine (n = 26) or placebo (n = 27), plus standard of care for 25 days. The primary endpoint was the change in Montgomery-Åsberg Depression Rating Scale (MADRS) total score from baseline to Day 2. The MADRS score improved in favor of esketamine (least squares mean difference: −3.8). No unexpected safety concerns were noted. The Asian subgroup showed a similar efficacy and safety profile as the total ASPIRE I cohort.
