NCT ID NCT07227454

First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times

Summary

This study tests whether a nasal spray containing esketamine, given alongside standard care, can rapidly reduce symptoms of major depression and suicidal thoughts in adolescents. About 258 teens with acute suicidal ideation or behavior will receive either esketamine or a psychoactive placebo. The main goal is to see if depression scores improve within 24 hours and last through 25 days.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Esketamine (a nasal spray form of ketamine)
What this could lead to
If it works, this could provide a fast-acting option to ease severe depression and suicidal thoughts in teenagers, potentially saving lives during a crisis.
What could go wrong
This is a Phase 3 trial, but it's still experimental. Esketamine can cause side effects like dizziness, nausea, or dissociation. The placebo used is a psychoactive drug (midazolam), which may complicate results. Success is not guaranteed.
