A Randomized, Double-blind, Placebo-controlled, Dose-ranging Trial of Oral Inosine to Assess Safety and Ability to Elevate Urate in Early Parkinson's Disease
In Brief
A Phase 2 clinical trial evaluating Placebo and inosine for Parkinson Disease. Completed, enrolled 75 participants across 16 sites.
Detailed 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.

500 mg of inactive substance per capsule; 1 to 6 capsules per day (in up to 3 divided doses) for 2 years; dosing adjusted algorithmically to parallel that in the inosine arms
500 mg of active substance per capsule; 1 to 6 capsules per day (in up to 3 divided doses) for 2 years; dosing titrated to a mildly elevated serum urate range of 6.1 - 7.0 mg/dL
500 mg of active substance per capsule; 1 to 6 capsules per day (in up to 3 divided doses) for 2 years; dosing titrated to a moderately elevated serum urate range of 7.1 - 8.0 mg/dL
