Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people clinically diagnosed with gout by ACR/EULAR criteria who do not have diabetes, hypertension, hyperlipidemia, cardiovascular or neurological disease, active infections, other inflammatory or autoimmune diseases, impaired liver or kidney function, current biologic therapy, or metformin hypersensitivity.
✕Probably not a fit
Patients with comorbid conditions listed as exclusions (such as diabetes, cardiovascular disease, impaired renal or liver function), those on biologics, or those allergic to metformin would be excluded and are unlikely to benefit from participation.

What this trial studies
This Phase 2 interventional trial compares metformin to a placebo in people diagnosed with gout to gather safety and efficacy data. Participants will receive either metformin or placebo and be monitored for gout-related outcomes and adverse events over the treatment period. Key exclusions include patients with cardiovascular disease, hypertension, hyperlipidemia, diabetes, active infections, other inflammatory or autoimmune diseases, those on biologic therapies, and anyone with impaired liver or kidney function or metformin hypersensitivity. The trial is being conducted at a single site at Tanta University.
Why it matters
Potential benefit: If successful, metformin could provide a low-cost, well-tolerated option to reduce gout flares and improve quality of life for people with gout.
How similar studies have gone: Metformin has shown anti-inflammatory and cardio-renal protective effects in observational and preclinical work, but its specific use to treat gout is largely untested in randomized clinical trials.
