In treatment-resistant depression, esketamine nasal spray combined with an SSRI or SNRI led to remission in 27.1% of patients at week 8, compared to 17.6% for extended-release quetiapine plus an SSRI or SNRI. Over 32 weeks, 21.7% of patients on esketamine had no relapse after remission versus 14.1% on quetiapine. The open-label, single-blind, randomized trial included 676 patients. Adverse events matched known safety profiles. Esketamine was superior to quetiapine for achieving remission and preventing relapse.
