How a New Depression Treatment Works in Real Life

This is an observational study that follows people with treatment-resistant depression—depression that hasn't improved with at least two other antidepressants—who are now being treated with esketamine nasal spray. The study tracks how well the medication works, who benefits most from it, and how it affects your daily life, relationships, and ability to work or do activities you care about.

Many people with depression find that standard antidepressants don't help them. This study exists to understand whether this medication can help people whose depression has been hard to treat, and to learn which patients are most likely to improve so doctors can better match treatments to individual patients.
