Key clinical point: Patients with depression who had achieved remission were significantly less likely to relapse when esketamine nasal spray was added to their oral antidepressant.
Major finding: Relapses occurred in 26.7% of patients in the esketamine and antidepressant group, compared with 45.3% of the placebo group.
Study details: The data come from the SUSTAIN-1 trial, a multicenter, double-blind, randomized withdrawal study of 297 adults with stable remission of depression.
Disclosures: Dr. Daly and several coauthors are employees of Janssen Research and Development, which funded the study.
