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

Summary

This study looks at whether mild whole-body hyperthermia (raising body temperature to about 101.3°F) can help treat major depression by affecting the immune system. Researchers will give some participants a drug that blocks IL-6 (tocilizumab) and others a placebo before the heating session to see if IL-6 is key to the antidepressant effect. The study involves 35 adults with moderate to severe depression and is currently on hold.
