This study will evaluate the safety and effectiveness of a new drug being developed to treat people who suffer from uncontrollable movements (dyskinesias) caused by Parkinson’s disease treatment.

Summary Abstract:
It is common among people who have had Parkinsons disease (PD) for several years to develop uncontrollable movements (Dyskinesias) due to the drugs they take to control the symptoms of PD.
