Summary

This study tests whether the anti-inflammatory drug celecoxib can help people with a specific type of depression linked to inflammation, called immuno-metabolic depression (IMD). Researchers will give 140 people with IMD either celecoxib or a placebo, in addition to their usual depression treatment, for 12 weeks. The goal is to see if targeting inflammation improves depressive symptoms more than usual care alone.

What this could mean

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

Active substance
Celecoxib (an anti-inflammatory drug, 400 mg daily)
What this could lead to
If it works, this could lead to a new, personalized treatment option for people with depression who have signs of inflammation.
What could go wrong
This is a phase 3 trial, but it's still relatively small (140 people) and only tests one type of anti-inflammatory. The drug may not work better than placebo, and long-term effects are unknown.
