Summary

This phase 2 trial tests whether disulfiram, a drug already approved for alcohol use disorder, can safely reduce joint inflammation in people with rheumatoid arthritis who are overweight. Twenty adults with active arthritis despite standard treatment will take either disulfiram or a placebo daily for 12 weeks. The study focuses on safety and early signs of effectiveness.

What this could mean

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

Active substance
Disulfiram
What this could lead to
If it works, this could point toward a new way to control inflammation in rheumatoid arthritis, especially for patients who are overweight.
What could go wrong
This is a small, early pilot trial with only 20 people, so results may not apply widely. Disulfiram can cause serious reactions if alcohol is consumed, and its benefit for arthritis is unproven.
