EASE LID Study: Drug to Treat Levodopa Induced Dyskinesia

Clinical Trial Title: 
EASE LID study: ADS-5102 for the treatment of levodopa induced dyskinesia
Clinical Trial Protocol ID: 
Clinical Trial Investigator Name: 
Leo Verhagen Metman, MD, PhD
Clinical Trial Protocol Description: 

This is a multi-center, randomized, double-blind, placebo-controlled, study to evaluate the effectiveness and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, taken once nightly at bedtime for the treatment of levodopa induced dyskinesia (LID) in subjects with Parkinson's disease (PD). ADS-5102 is an extended release (ER) formulation of amantadine and is designed to be taken by mouth once nightly at bedtime, providing a slow release of amantadine into the bloodstream. It is hoped that the low amount of drug in the bloodstream in the evening and overnight may reduce some side effects, including difficulty sleeping and vivid dreams, which can occur with use of immediate-release amantadine. Up to 6 subjects are anticipated to be enrolled in this study at Rush with up to 90 subjects study-wide. Subject participation is anticipated to last up to 4 months with the opportunity to participate in an open-label extension study.
