Safety and Efficacy Study of PEG-uricase in the Treatment of Hyperuricemic Patients With Symptomatic Gout

Summary

These are two replicate studies to evaluate the safety and efficacy of PEG (polyethylene glycol)-uricase in controlling the uric acid level in symptomatic gout patients with high uric acid levels who are unable to take standard gout therapies, or for whom those therapies have been unsuccessful in controlling their uric acid level.
