Study Summary
This study will test the effectiveness of an experimental drug called LY300164 on improving Parkinson's disease symptoms, such as movement impairments and tremor, as well as involuntary movements produced by long-term treatment with levodopa. Patients with relatively advanced (Stage II to IV) Parkinson's disease between 30 and 75 years of age may be eligible for this 8-week study. Participants will have a complete medical history and physical examination, including blood tests and an electrocardiogram, and possibly brain magnetic resonance imaging (MRI), CT scan, and chest X-ray. Patients will stop taking all anti-parkinsonism medications except levodopa (Sinemet) and the experimental drug during the study. For the first 1 to 3 days, patients will be in the hospital for a levodopa "dose-finding" procedure. For this study, levodopa is infused through a vein for up to 8 hours, with symptoms monitored frequently to determine the doses that will produce two results: 1) the dose that is less than what is needed to relieve symptoms, and 2) the dose that relieves symptoms, but may produce dyskinesias. When these dose rates are determined, patients will begin treatment in one of two groups. One will take LY300164 3 times a day, along with levodopa, for 3 weeks. The second group will take placebo tablets (a look-alike tablet with no active ingredient) and levodopa on the same schedule as the LY300164 group. A brief medical examination and routine blood and urine tests will be done weekly. The drug dose will be increased every 3 to 4 days until significant side effects occur or the maximal dose is reached. Patients will be closely monitored for 4 hours after every increase. At the end of the 3 weeks, or when the maximal dose is reached, patients will be readmitted to the hospital for 2 to 3 days for a second levodopa dose-finding study, while continuing on LY300164 or placebo. After this test, patients will resume taking levodopa and the experimental drug or placebo as bef
