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 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.
