Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This will be a double-blind, randomised, placebo-controlled parallel-arm phase II proof of concept in subjects with PD treated with a stable dose of levodopa who are experiencing both end-of-dose wearing off and Levodopa-Induced Dyskinesia (LID)
