Active clinical trials for "Parkinson Disease"

To establish the efficacy of 40 mg/day doses of istradefylline for the change in Unified Parkinson's Disease Rating Scale (UPDRS) part-III (Motor examination) score in patients with Parkinson's disease (PD).

The purpose of this study was to evaluate the differences in safety and efficacy between Parkinson's disease patients who either received transplantation of fetal porcine cells or placebo treatment.

The purpose of this study is to evaluate the safety and efficacy of the long-term treatment of entacapone in patients with Parkinson's disease with end-of-dose wearing-off. This study is not recruiting patients in the United States.

The objective of this study is to compare the pharmacokinetics and pharmacodynamics of IPX054, carbidopa-levodopa immediate-release tablets, and carbidopa-levodopa controlled-release tablets in subjects with idiopathic Parkinson's disease.

Study to look at the effectiveness, tolerability and safety of two doses of Rasagiline (0.5 mg and 1mg) in advanced Parkinson's Disease (PD) Patients who have been treated with Levodopa/Carbidopa therapy.

The objective of this study was to measure the continued efficacy of apomorphine after previous exposure of at least three months duration.

Study to measure the continued effectiveness of apomorphine after previous exposure of at least three months duration.

This is a 1-year, open-label, long-term safety extension for patients who have completed prior istradefylline studies 6002-EU-007, 6002-US-013 or 6002-US-018.

The primary purpose of this study is to evaluate the efficacy, safety, and tolerability of 40 mg per day of istradefylline (KW6002) as monotherapy in patients with Parkinson's disease.

The purpose of this study is to study different kinds of dyskinesias in advanced Parkinson's disease appearing at different levels of levodopa infusion dose. The hypothesis is that different dyskinesias (dystonia, chorea) correlate to different levels of levodopa concentrations, as detected in plasma.
