Active clinical trials for "Parkinson Disease"

The objectives of this trial conducted in early Parkinson's disease (PD) patients are: To assess if patients with early Parkinson's disease (PD) can be successfully switched (overnight switching) from Pramipexole (PPX) Immediate Release (IR) to Pramipexole Extended Release (ER). A successful switch at a specific visit is defined as no worsening of the Unified Parkinsons Disease Rating Scale (UPDRS) parts II+III score by more than 15% from baseline and no drug-related adverse events leading to withdrawal; To establish if this successful switch can be obtained with or without dose-adaptation; To provide information about the conversion ratio (mg:mg) from Pramipexole IR to Pramipexole ER.

Parkinson' disease is a neurodegenerative disorder characterised by bradykinesia, rigidity, rest tremor and postural instability. Dopaminergic therapy such as L-Dopa and dopamine agonists usually leads to a dramatic improvement of symptoms, but disease progression nevertheless remains inevitable. Bilateral Deep brain stimulation in subthalamic nucleus (STN) leads to a spectacular clinical improvement in patients with motor complications and is now considered as the gold standard surgical treatment. However, this surgery induces a post-operative body weight gain which may limit the benefits of this technique and induce critical metabolic disorders such as profound alterations in the central control of energy metabolism. Previous data seems to show that glucose metabolism is also altered. The aim of this prospective study was to identify if the STN stimulation could modify glucose metabolism regulation especially the endogen glucose production (by liver) Hypothalamus is able to detect glucose concentration variations and to control/adjust glucose levels by modulating the hepatic glucose production. As hypothamus and STN are anatomically closed, we hypothesise that the STN stimulation could modulate the hypothalamus function and consequently modify glucose production.

Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO-B, the major DA metabolising enzyme in man. Safinamide is an inhibitor of MAO-B. This is a phase III trial to evaluate the efficacy and safety of safinamide (50 and 100 mg p.o. q.a.m.) compared to placebo as add-on therapy to a stable dose to levodopa in subjects with advance idiopathic Parkinson's Disease. The principal efficacy measure is the increase in mean daily "on" time during the 18-hr diary recording period.

The general aim of this study is to obtain long-term safety and tolerability data on pramipexole ER, in daily doses from 0.375mg to 4.5mg once daily (q.d), in patients who have previously completed a pramipexole double-blind study in early PD (248.524(NCT00479401) or 248.636(NCT00558025) trial).

To evaluate the safety profile of ropinirole XL during long-term treatment in subjects with early and advanced Parkinson's disease

To determine the long-term safety and efficacy of a dose range of safinamide of 50-200 mg/day, p.o., compared to placebo, as add-on therapy in patients with early idiopathic Parkinson's disease who are currently receiving a stable dose of a single dopamine (DA) agonist.

This clinical trial is designed to evaluate the safety and potential efficacy of Xyrem for the treatment of excessive daytime sleepiness (EDS) and nocturnal sleep disturbance in patients with mild to moderate Parkinson's Disease (PD).

This study was designed to evaluate the symptomatic effects or potential disease progression slowing down effect of a kind of Herbal Medicinal Mixture in Parkinson's disease (PD) patients. The treatment phase includes 12 months period of Herbal Medicinal Mixture per day or placebo and 1 month wash-out period without herbal medicine and placebo.

The purpose of this study is to obtain information on the long-term safety, tolerability, and therapeutic benefit of extended release ropinirole XL, and to provide a mechanism for patients who participated in either Study 167 or Study 164 to continue receiving ropinirole XL if they chose to do so.

Patients with Parkinson's disease who completed the prior double-blind study 6002-009 are eligible to enter into this long-term study. The purpose of this study is to evaluate the safety and efficacy of KW-6002 administered long-term in patients with advanced Parkinson's disease treated with levodopa.
