2.Levodopa-responsive idiopathic Parkinson’s disease (PD) patients receiving carbidopa/levodopa (immediate release or sustained-release forms (or both), optimally managed with levodopa intake of no more than 600 mg/day.
-Evaluable patients will need to have levodopa-induced peak-effect dyskinesias.
- Female patients must not be of childbearing potential (e.g., surgically sterile or be at least one year post-menopausal).
- Patients must be willing and able to abide by the dietary requirements of the study
- Patients must be willing and able to abide by the restrictions on concomitant medication use that are outlined (restrictions to be determined-see section 9.6).
- Patients must be willing to cooperate with study procedures and to be confined within the clinical site’ designated facility overnight, including three consecutive nights.
