Summary

This study tests whether ketamine injections combined with psychotherapy can help people with treatment-resistant depression. Researchers will use brain scans to see if changes in brain activity link to improvements. About 25 adults will receive 1-2 doses of ketamine and several therapy sessions over two months.

What this could mean

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

Active substance
ketamine hydrochloride injection
What this could lead to
If it works, this could point toward a faster-acting treatment for depression that doesn't respond to standard antidepressants.
What could go wrong
This is a small, early-phase study with only 25 people, so results may not apply widely. Ketamine can cause dissociative side effects, and the benefit may not last.
