Levodopa-Induced Dyskinesia in Parkinson Disease Treatment Study

Clinical Trial Title: 
Safety and efficacy study of an extended release treatment for levodopa-induced dyskinesia in Parkinson’s disease
Clinical Trial Protocol ID: 
11033103
Clinical Trial Investigator Name: 
Leo Verhagen, MD, PhD
Clinical Trial Protocol Description: 

This study will evaluate the safety, effectiveness and tolerability of three dose levels of an extended release treatment of levodopa-induced dyskineisa (LID). The three doses of the study drug are similar to doses of an already approved by the FDA for treatment of Parkinson’s disease (PD); however doses in this study are higher than those usually prescribed for PD. One of the goals of this clinical study is to understand what dose of study drug may work best for treatment of LID. It is anticipated that 80 subjects will participate in this study at about 25 centers (with up to four subjects at Rush). Subjects who agree to participate will be in the study for about three months, will need to come to Rush for eight study visits and will have one telephone visit.

Clinical Trial Eligibility Criteria: 

In order to participate you must meet the following criteria:

  • Have a diagnosis of Parkinson disease.
  • Are 30 to 80 years of age, inclusive.
  • Are ambulatory or ambulatory-aided (e.g., walker or cane) ability while ON, such that study assessment can be completed.
  • Have a knowledgeable and reliable caregiver/study partner who can accompany you to study visits and assist with the completion of study instruments, as needed and allowed.
  • Have followed a stable regime of antiparkinson medication for at least 30 days prior to screening.
