Active clinical trials for "Parkinson Disease"

The objectives of this study were to evaluate the efficacy, safety, and tolerability of pramipexole, as single-agent therapy or in combination with levodopa, in patients with Parkinson disease living in Hong Kong and Taiwan.

This is an extension study to evaluate the long-term safety and tolerability of ABT-SLV187 in subjects with advanced Parkinson's disease.

Sleep wake disturbance is a common problem in Parkinson's disease patients and so far the therapeutic possibilities for symptomatic relief are limited. Small, open-label studies indicate that the use of Xyrem (gamma-hydroxybutyrate) might be of benefit in this situation. This study is intended to show a beneficial effect of the study medication in a randomized cross-over trial, that fulfills strict scientific criteria.

A higher prevalence of Helicobacter pylori infection rate has been demonstrated among PD patients compared to controls. As H. pylori infection is known to interfere with levodopa absorption, we embarked on this is a study to understand the effects of Helicobacter pylori infection eradication among a selected Malaysian population with Parkinsons disease, in relation to levodopa effectiveness and motor improvements. The study hypotheses are: H. pylori eradication improves L-dopa 'onset' time and prolongs the L-dopa 'on-time' duration. PD patients with H. pylori infection show clinical improvement in motor disability and quality of life after eradication therapy of H. pylori, assessed using UPDRS-III / PDQ39 questionnaires.

The purpose of this study is to see if the study drug, Mirabegron, is safe and effective in treating symptoms of Overactive Bladder in people with Parkinson's Disease.

This is a single-center, unblinded trial without placebo control to evaluate the acute effects of caloric vestibular stimulation on UPDRS motor scores in Parkinson's Disease patients.

Excessive free radical formation and depletion of the brain's primary antioxidant, glutathione, are established components of Parkinson's disease (PD) pathophysiology. While there is rationale for the therapeutic use of reduced glutathione (GSH) in PD, and even some preliminary evidence to suggest the use of GSH can lead to symptomatic improvement, obstacles surrounding currently employed delivery methods have hindered the clinical utility of this therapy. Intranasal GSH, (in)GSH, is a novel method of glutathione augmentation. The aim of this study is to evaluate whether 200 mg of (in)GSH results in measurable changes in brain glutathione concentrations, as measured by magnetic resonance spectroscopy (MRS) in 15 individuals with PD.

The primary objective of this study is to evaluate the efficacy, tolerability and safety of single treatments of APL-130277 in 16 patients with Parkinson's Disease (PD)

Study to assess and compare the safety of long term oral treatment for Parkinson's Disease with pramipexole versus bromocriptine or other dopamine agonists, by measuring cross-sectional the incidence of ophthalmologic disturbances, especially signs of retinal degeneration, in a matched pair design

Several animal and human epidemiologic studies have provided evidence that exercise may be neuroprotective in Parkinson's disease (PD). Exercise may forestall diagnosis and, in the case of those who have already been diagnosed with PD, it may slow the observed neurodegeneration. Unfortunately, because this line of research is in early stages, there is little evidence to indicate what biological mechanisms underlie the neuroprotection that is conferred with exercise. Toward this end, it is possible that an interaction between endogenous antioxidant enzymes, inflammatory processes, and reactive oxygen species may be associated with exercise improvements in PD. One of the most common reasons for premature death in PD is falls. Several meta-analyses have concluded that exercise training programs focused on balance and/or strength training are effective at improving aspects of balance. Taken together, the current body of evidence suggests that exercise may be neuroprotective and balance/strength training may decrease the likelihood of a fall. The combination of these efficacious treatment modalities (exercise and balance/strength training) in a comprehensive treatment approach to improve PD symptoms and balance has been previously reported at relatively mild or moderate exercise intensities. Because recent research has suggested that patients with PD may benefit more from more physically intense programs, we are proposing a more aggressive approach with regard to exercise intensity and frequency in the present trial. The primary purpose of this study is to determine the feasibility and safety of a high intensity exercise approach to PD. A secondary purpose is to determine the trajectory of change in outcomes over the duration of the trial from a high intensity fall prevention program. It is hoped that a signal of efficacy will allow this trial to progress to a comparative effectiveness trial. An important innovative design element is collecting biological assays to better understand the mechanism underlying the anticipated clinical improvements. Aim 1 is to test the feasibility of a high-intensity exercise and fall prevention boot camp (HIBC) in patients with PD by analyzing adherence and whether they achieve minimum Centers for Disease Control exercise standards (150 min/wk moderate level aerobic exercise; strengthening at least two times per week) for the duration of the trial. Aim 2 is to determine if participation in an 8-week HIBC under the direction of a physical therapist is safe for individuals with PD. Secondary Aim 3 is to determine if participation in an 8-week HIBC will produce a signal of efficacy for several physical outcomes: falls per physical activity ratio, balance efficacy, motor activity, fatigue, muscle strength, bone health, cognition/mood, and quality of life. Secondary Aim 4 is to determine if participation in an 8-week HIBC will produce a signal of efficacy for biological outcomes, anti-inflammatory cytokines and anti-oxidant enzymes. An additional exploratory aim will be an analysis of BDNF val66val, val66met, met66met polymorphisms to determine if there is a differential response to exercise. This trial is innovative because it utilizes a high intensity comprehensive exercise treatment approach (aerobic exercise, strengthening, and balance training). To our knowledge, there have been no trials of individuals with PD who have participated in a trial of this intensity in a group "boot camp" setting. Another innovative design element is the use of three novel assessments: biological assays of pro- and anti-inflammatory cytokines, endogenous anti-oxidant enzymes and a novel assessment of falls (falls per physical activity ratio). Participants will be randomly assigned into either an 8-week HIBC group or an 8-week usual care control group (standard, low intensity group therapy class) under the direction of physical therapists. Each group will have 15 participants with a 1:5 patient-to-therapist ratio. The HIBC will be 1.5 hours daily, Monday through Friday. Participants will be required to attend 3 out of the 5 days. The protocol of the HIBC will include the following exercise components: A. 30 minutes of moderate-high intensity aerobic exercise; B. 15 minutes of strengthening the major muscle groups; C. 15 minutes of balance training; and, D. 15 minutes of interspersed rest and stretching. Participants will rotate through these four exercise components. Participants will have one baseline test and assessments at the 2-week, 4 week, 8-week, and 6-month points. Outcomes of the primary aims (Aim 1 and Aim 2) will be frequency counts of participation, adverse events, and compliance with exercise. The outcomes for the secondary aims will include measures of balance and falls, physical capacity, fatigue, exercise/physical activity behavior, and biological assays.
