Safety and Efficacy Study of SYN115 in Parkinson's Patients Using Levodopa to Treat End of Dose...
Parkinson's DiseaseThe purpose of this research study is to test the effect of SYN115 compared to placebo (a "sugar pill" that looks like SYN115 but does not include active drug) on movement during the "on" and "off" states as well as other symptoms that some patients with Parkinson's disease experience. This study will also look at whether or not patients with Parkinson's disease experience "side-effects" with SYN115.
ADX48621 for the Treatment of Levodopa Induced Dyskinesia in Patients With Parkinson's Disease
Parkinson's DiseaseThe primary objective of the study is to evaluate the safety and tolerability of ADX48621 in Parkinson's disease patients following four weeks of dosing. The secondary objectives of the study include the evaluation of the efficacy of ADX48621 compared with placebo in reducing levodopa induced dyskinesia in patients with Parkinson's; the evaluation of the effect of ADX48621 on symptoms of Parkinson's disease and patient ability to function, and the evaluation of the effect of coadministration of ADX48621 on L-dopa efficacy.
Intravenous N-acetylcysteine for the Treatment of Gaucher's Disease and Parkinson's Disease
Parkinson's DiseaseGaucher's DiseaseThe investigators are interested in determining if the investigators are able to detect changes in brain chemistry using Magnetic Resonance Spectroscopy (MRS) in individuals with Parkinson's disease (PD), those with Gaucher's disease (GD), and those without neurological disorders (healthy controls) when they are given the antioxidant N-acetylcysteine (NAC). This study will combine information from a medical history, a physical examination and disease rating scales with results obtained using MRS brain scans and pharmacokinetic studies from blood samples. This research will require 1 visit that will require about 4 to 5 hours of time. During this study, participants will provide their medical history, be examined and undergo a rating scale for about one hour; the brain scan and pharmacokinetic studies will require 1.5-2 hours of time; in total the study will take about 4-5 hours.
Behavioral Therapy to Treat Urinary Symptoms in Parkinson Disease
Urinary IncontinenceNocturiaParkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms of tremor, slowness of movement, and stiffness, leading to progressive disability and loss of independence. Lower urinary tract symptoms (LUTS), including urinary incontinence (UI), urgency, and/or nocturia, are common non-motor symptoms that further diminish the already compromised quality of life for adults living with PD. Behavioral interventions for UI - including pelvic floor muscle exercise (PFME) therapy - have proven efficacy in randomized controlled trials and are free of side effects. Exercise-based behavioral therapy for UI requires individuals to learn a motor skill (PFME) and implement an adaptive behavioral strategy that incorporates the PFME to suppress urinary urgency and prevent UI. We will conduct a two-site, randomized controlled trial to assess the efficacy of PFME-based behavioral therapy to treat urinary symptoms in adults with PD. After stratification by UI severity, PD severity, and gender, a group of 60 subjects (30 in each group) will be randomized to receive behavioral therapy or a behavioral control over 8 weeks in order to achieve a sample size of 50 individuals (25 in each group) who complete the study. A 6-month follow-up is planned in the treatment group. We hypothesize that: PD participants who are randomized to the exercise-based behavioral therapy group (Group A) will report a significant reduction in weekly frequency of UI episodes compared to PD participants in the behavioral control group (Group B). The primary outcome, frequency of UI, will be measured using a seven-day bladder diary. Compared to PD participants in Group B, the reduction in UI frequency in Group A will be clinically meaningful as measured by a corresponding improvement on questionnaires of satisfaction and quality of life as well as a decline in other urinary symptoms including urgency and nocturia.
An Open-label Safety Study of Pimavanserin in Parkinson's Disease Patients
Parkinson's Disease PsychosisThis is an open-label extension study to assess the long-term safety and tolerability of pimavanserin (ACP-103) in subjects with Parkinson's Disease Psychosis (PDP).
Exercise Interventions in Parkinson's Disease
Parkinson's DiseaseThis study sets out to determine the effect of exercise performed over a longer period of time (6 months), delivered using community facilities, on motor and non motor symptoms, health and well being in people with Parkinson's Disease.
Ropinirole PR Pharmacokinetics Study Among Chinese Healthy Subjects
Parkinson DiseaseThe purpose of this study is to investigate the pharmacokinetic profile of ropinirole PR after single and multiple doses of the PR-formulation. It will also investigate the safety and tolerability of ropinirole PR after single and multiple doses of PR-formulation.
Study of Safety, Tolerability, Pharmacokinetics, and Efficacy of ABT-SLV187 in Subjects With Advanced...
Advanced Parkinson's DiseaseTo explore the safety, tolerability, pharmacokinetics and efficacy of ABT-SLV187 in advanced Parkinson's disease (PD) patients with severe motor complications. The complications of medical devices for the naso-jejunum (NJ) infusion system of ABT-SLV187 will also be investigated.
Pramipexole Extended Release Versus Pramipexole Immediate Release for 18 Weeks in Chinese Parkinson's...
Parkinson DiseaseThe objective of this trial is to evaluate non-inferiority of pramipexole Extended release to Immediate release at 18 weeks on the primary efficacy endpoint (Unified Parkinson's Disease Rating Scale II+III) in Chinese PD patients who can be concomitantly treated with Levodopa .
Select Stim: Selective Stimulation of the Subthalamic Nucleus in Parkinson's Disease. "A Feasibility...
Parkinson DiseaseIn the advanced stages of Parkinson Disease deep brain stimulation of the subthalamic nucleus (STN DBS) is the next therapeutic option. Despite the beneficial motor effects there are important negative side-effects of STN DBS. Our hypothesis is that changes in cognition and behavior during STN DBS are related to stimulation of the non-motor parts of the STN. The primary objective is to avoid cognitive and affective side effects by selective stimulation of the STN motor part. The main objective of this feasibility study is to measure the patients burden and to test the technical feasibility. Intervention: The intervention is an expansion of the classical STN DBS procedure. The targeting using the multichannel registration system by stimulation of the motor cortex and registration of the subthalamic nucleus will be added to the procedure. For this procedure, it is necessary to place a subdural strip under the skull.
