NCT ID NCT03748446

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests whether inhaling a low dose of xenon gas can quickly improve depressive symptoms in 20 people with treatment-resistant major depression or bipolar depression. Participants receive either xenon or a placebo gas added to their usual treatment, and researchers measure changes in depression scores. The goal is to see if xenon can provide rapid relief, but the study is very small and preliminary.
