Active clinical trials for "Parkinson Disease"

This is a study to evaluate peripheral vibrotactile coordinated reset stimulation for Parkinson's disease seeks to explore the safety and efficacy of an experimental non-invasive method to aid in the symptoms of Parkinson's disease. The purpose of the study is to verify the safety and tolerability of non-painful sensory (tactile) vibratory stimulation delivered to the fingertips of patients with Parkinson's disease.

Evaluate the clinical efficacy and safety of droxidopa versus placebo over a 17 week (maximum) treatment period in patients with symptomatic NOH.

The purpose of this study is to assess the safety and tolerability of a dose of 95μg sNN0031 after intracerebroventricular administration to patients with Parkinson's disease

The purpose of this multi-center, randomized, double-blind, parallel-group, 26 week study is to compare the efficacy and safety of two different dose levels of Amantadine Extended Release Tablets to placebo for the treatment of levodopa induced dyskinesia in patients with Parkinson's disease.

An experimental drug called L-DOPS increases production in the body of a messenger chemical called norepinephrine. Cells in the brain that make norepinephrine are often gone in Parkinson disease. The exact consequences of this loss are unknown, but they may be related to symptoms such as fatigue, depression, or decreased attention that occur commonly in Parkinson disease. This study will explore effects of L-DOPS in conjunction with carbidopa and entacapone, which are drugs used to treat Parkinson disease. We wish to find out what the effects are of increasing norepinephrine production in the brain and whether carbidopa and entacapone augment those effects. Volunteers for this study must be at least 18 years of age and able to give consent to participate in the study. To participate in the study, volunteers must discontinue use of alcohol, tobacco, and certain herbal medicines or dietary supplements, and must also taper or discontinue certain kinds of medications that might interfere with the results of the study. Candidates will be screened with a medical history and physical exam. Participants will be admitted to the National Institutes of Health Clinical Center for two weeks of testing. The study will have three testing phases in a randomly chosen order for each participant: Single dose of L-DOPS Single dose of L-DOPS in conjunction with carbidopa Single dose of L-DOPS in conjunction with entacapone Each phase will last two days, with a washout day between each phase in which no drugs will be given and no testing will be performed. In each phase, participants will undergo a series of tests and measurements, including blood pressure and electrocardiogram tests. Participants who are healthy volunteers will also have blood drawn and will undergo a lumbar puncture (also known as a spinal tap) to obtain spinal fluid for chemical tests.

Tolerability and Efficacy of Spheramine will be evaluated after operative implantation (Stereotactic Intrastriatal Implantation) in patients with advanced Parkinson's Disease

Randomised, double-blind, double dummy, parallel group design. Following the screening period patients will be randomised at the baseline visit, in a 1:1:1 manner, to one of three treatment arms; 4 mg E2007, 200 mg entacapone (with each dose of levodopa) or placebo. The first 4 weeks of the double blind phase will be used to titrate patients on the E2007 arm from 2 mg up to the maintenance dose of 4 mg. Patients randomised to entacapone or placebo will have dummy up titrations to maintain the blind. Following this titration phase, patients will remain on the maintenance dose for a further 14 weeks. Patients will have visits at 2, 4, 6, 10, 14 and 18 weeks after baseline. A follow up visit will be performed at Week 22. A home diary will be completed in which patients rate themselves as either: "OFF" "ON" without dyskinesias "ON" with non-troublesome dyskinesias "ON" with troublesome dyskinesias Asleep These entries will be completed every 30 minutes during the waking day and will be completed for three consecutive days immediately prior to visits at Baseline, Weeks 6, 10, 18 and 22. At Baseline (Day 0), week 10 and 18 the Unified Parkinson's Disease Rating Scale (UPDRS - Parts I, II , III and IV) will be performed. At the end of the treatment period (Week 18), patients will undergo final efficacy and safety assessments and will stop taking the study medication they were receiving. They will be seen 4 weeks later for a follow up visit.

The dopamine agonists, pramipexole (Mirapex) and ropinirole (Requip), are drugs that are used to treat symptoms of Parkinson's disease. However, these drugs can induce bothersome leg swelling or edema in about 20 percent of patients. The cause of this edema is unknown but may be secondary to stimulation of peripheral dopamine receptors in the kidney or blood vessels. We hypothesise that a peripherally acting dopamine receptor antagonist, will reduce edema in PD patients. This study will assess the effect of the peripheral acting dopamine D2 receptor antagonist, domperidone as a potential treatment for dopamine agonist-induced leg swelling.

The study will assess the relative benefit of cabergoline vs carbidopa/levodopa therapy in treating nighttime problems of Parkinson Disease.

The purpose of this study is to establish safety for CEP-1347 and to determine an efficacious dose in the treatment of Parkinson's disease.
