Summary

This phase 2 trial tests whether suvorexant (Belsomra), a drug approved for insomnia, is safe and tolerable for veterans with major depression who are at high risk for suicide. Thirty veterans will take the drug nightly for four weeks, with in-person and remote check-ins. The study focuses on safety and feasibility, not yet on whether it actually reduces suicide risk.

What this could mean

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

Active substance
Suvorexant (Belsomra), a sleep medication that blocks orexin in the brain
What this could lead to
If it works, this could point toward a new way to reduce suicide risk by targeting brain chemistry linked to impulsivity and stress.
What could go wrong
This is a very early, small proof-of-concept study with only 30 veterans, so results may not apply to others. The drug is being tested for a new purpose, and side effects or lack of effect are possible.
