Gout Clinical Trials

Gout is characterized by episodes of acute arthritis of the lower limbs due to intermittent activation of innate immunity in the joints where urate crystals have formed. These crystals occur when serum urate (SUA) levels have been above 70 mg/L for many years. They can be dissolved by lowering SUA levels to at least 60 mg/L (treat-to-target - T2T - strategy). Once the crystals are dissolved, patients are no longer symptomatic and are considered to be in remission (treat-to-dissolve - T2D - strategy). The presence of crystals and their dissolution during treatment can be monitored by repeated ultrasound (US) scans of the feet and knees. The time required for complete dissolution varies from patient to patient. ReViGore40 is a cohort designed to i) determine the time to complete dissolution of urate deposits in joints when SUA levels are maintained below 40 mg/L, ii) determine the factors (clinical, biological, genetic) associated with the time required for complete dissolution of urate deposits within joints.
