简要总结
The study will establish efficacy and safety of rasburicase in chronic gouty arthritis
详细描述
The study hypothesis is that the proportion of patients who achieved the primary endpoint after 12 weeks of treatment with rasburicase combined with oral urate-lowering therapy is superior to 12 weeks of treatment with oral urate-lowering therapy.
