NCT07089888
The primary objective of this study is to evaluate the efficacy of dotinurad in lowering serum uric acid (sUA) at Week 24 compared with allopurinol in adult participants with tophaceous gout.
NCT07116746
This study will assess the effect of AR882 and XOI co-administration on sUA lowering as well as reducing tophus burden in the population that has failed uricase treatment (eg., pegloticase). Failed uricase treatment is defined as having an inherent intolerance, anaphylaxis, infusion reaction, antibody development, and/or at least one sUA level that rose to greater than 6 mg/dL while on therapy.
NCT03965676
The main objective is to evaluate the decrease in crystalline volume of the target tophus using Dual-Energy Computed Tomography (DECT), after 6 months +/- 1 month of urate-lowering therapy with target uricemia. Study hypothesis * The dynamics of tophus resolution with urate-lowering therapy is poorly understood. * It is variable according to the location of the tophus, peri articular / intratendinous, but also probably at the feet / hands, the initial overall volume of the tophus, the initial crystal charge of the tophus. Knowledge of prognostic factors for tophus resolution will help determine the best target for treatment follow-up for each patient. * Erosions are the consequence of tophus. Tophus resolution could be associated with repair of erosions and stabilization of joint destruction.
