J&J Wins Monotherapy Use for Spravato
FDA has approved a Johnson & Johnson supplemental NDA for Spravato (esketamine) nasal spray for monotherapy use in treating adults with major depressive disorder who have had an inadequate response to at least two oral antidepressants. Previously, Spravato was approved for combination use with an oral antidepressant for treating adults with treatment-resistant depression and depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior.
Spravato is said to work by targeting glutamate, an “excitatory” neurotransmitter in the brain. J&J says that the “mechanism by which esketamine exerts its antidepressant effect is unknown.”
The current approval is based on data from a randomized, placebo-controlled study in which Spravato monotherapy “showed a rapid and superior improvement in Montgomery-Asberg Depression Rating Scale (MADRS) total score vs. placebo,” the company says. “In a post-hoc analysis, Spravato demonstrated numerical improvements across all 10 MADRS items at day 28. At week four, 7.6% of patients taking placebo and 22.5% of patients taking Spravato achieved remission…”
Spravato is dispensed under a Risk Evaluation and Mitigation Strategy program due to risks of “serious adverse outcomes resulting from sedation, dissociation, respiratory depression, abuse, and misuse,” J&J notes.
