Can a diabetes drug fight gout? metformin takes on febuxostat
NCT ID NCT06995339
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers compare two drugs, metformin and febuxostat, for lowering uric acid in obese adults who have gout but not diabetes. Both drugs may reduce uric acid, the substance that forms painful crystals in joints. The trial measures changes in blood uric acid levels over time. About 60 people will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- metformin and febuxostat
- What this could lead to
- If metformin lowers uric acid as well as febuxostat, it could offer an additional or alternative option for managing gout in obese people without diabetes.
- What could go wrong
- This is a small Phase 2 trial with 60 participants, so results may not hold in larger groups. Metformin can cause stomach upset, and febuxostat carries risks including liver problems and heart issues.
