Safety of Urate Elevation in Parkinson's Disease

Summary

The purpose of this study is to determine the safety and tolerability of inosine and its ability to raise urate levels in blood and cerebral spinal fluid in individuals with early Parkinson disease. This will determine whether it is appropriate to proceed with a larger study of inosine's ability to modify the rate of disability progression in PD.
