38 Clinical Trials for Various Conditions
The investigators propose a Phase I single surgical-center, double-blinded randomized parallel clinical trial involving bilateral autologous peripheral nerve tissue (PNT) delivery into the NBM or the alternate target also affecting cognition in this population, the substantia nigra (SN), to address "repair cell" support of these areas. Twenty-four participants with idiopathic Parkinson's Disease (PD) who have selected, qualified and agreed to receive as standard of care deep brain stimulation (DBS) will be enrolled and randomly allocated to receive bilateral PNT deployment to either the NBM or SN at the time of DBS surgery. Participants will be allocated equally among both assignments over the course of three years (8 Year 1, 10 Year 2, 6 Year 3). Participants will be evaluated for neurocognitive, motoric function, activities of daily living, and quality of life at enrollment before surgery, two-weeks after surgery, and 6, 12, and 24 months after surgery.
Learning deficits are frequent in individuals with Parkinson's Disease. Clear feedback is integral because through feedback individuals know whether they should stick with an action that they have been doing (if the feedback is positive), or change their course of action (if the feedback is negative). Learning though immediate feedback has been shown to be depended on the brain chemical dopamine that is disrupted in individuals with Parkinson's Disease. During learning, feedback can also be presented after a delay. The investigators propose that learning through delayed feedback will lead to greater learning in individuals with Parkinson's Disease, since learning through delayed feedback does not rely on dopamine. During the proposed paradigm, participants with Parkinson's Disease complete a multiple-choice test. After making their selection on the multiple-choice test, they either see feedback immediately or are given feedback 25 minute later after reviewing their selection on the multiple-choice test. The investigators hypothesize that participants will learn better when they are provided with delayed feedback.
This is a randomized, single-blinded, triple crossover study focused on determining the feasibility of using transcranial magnetic stimulation (TMS) for treatment of Parkinson's disease related autonomic dysfunction and depression. Participants will undergo TMS to three brain regions: medial prefrontal cortex (mPFC) (experimental site), dorsolateral prefrontal cortex (DLPFC) (alternative experimental site), or primary sensory cortex (S1) (control site) in a triple crossover design. Participants will complete symptom questionnaires, neurologic examination and cognitive assessments, and orthostatic vital signs recording before and after each brain stimulation session.
The purpose of this study is to examine the effects of Nordic pole walking exercise on walking function, movement and non-movement Parkinson-related symptoms, and certain exercise-related chemical indicators (bio-markers) in people with Parkinson's disease. This study will examine both the immediate and long-term effects of Nordic walking (NW) exercise on walking function, PD symptoms and exercise bio-markers after a supervised and individually progressed 6-week NW exercise training period and after a 3-month independent NW exercise phase. NW, as a task- specific exercise with higher energy demands than regular walking, has good practicality for independent walking exercise once the training program is completed. Therefore, this study will also examine independent NW exercise engagement after a supervised training program to assess feasibility and sustainability of this mode of task-specific aerobic exercise.
This study evaluates the role of subthalamic nucleus (STN) stimulation location and frequency on a range of cognitive processes in Parkinson's patients who have undergone Deep Brain Stimulation (DBS).
The major purpose of this study is to assess the efficacy of CBD on motor symptoms of Parkinson's Disease (PD), and secondarily to study the safety and tolerability of CBD and other efficacy, particularly regarding tremor in PD. The study has been powered to detect a clinically significant reduction in Movement Disorder Society (MDS) Unified Parkinson's Disease Rating Scale (UPDRS) Part III motor scores. This is a 1:1 parallel, double-blind, randomized controlled trial (RCT) with 60 participants. The investigators will be recruiting up to 75 participants; the goal is to have 60 participants (30 in CBD group and 30 in placebo group) complete the study. The study drug is obtained from the National Institute on Drug Abuse (NIDA).
Disruption of sleep and alertness is one of the most disabling non-motor symptoms of Parkinson's disease (PD). Mechanisms leading to impaired sleep and alertness in PD are not well understood, and treatment options remain limited. The proposed research will examine markers of the circadian system, sleepiness and sleep quality in PD patients. Further, the project will examine effects of bright light exposure on circadin function, sleep and alertness in PD.
The primary objective of this study is to examine the effect of LCIG relative to that of OMT on NMS associated with PD.
This trial is being conducted to assess the effects of Rotigotine over Placebo on improvement of Apathy and motor symptoms in subjects with early-stage and advanced stage idiopathic Parkinson´s Disease.
The purpose of this study is to assess the safety and feasibility of switching subjects with advanced Parkinson's Disease (PD) from Pramipexole or Ropinirole to Rotigotine and to assess the effects of Rotigotine on motor and non-motor symptoms of Parkinson's Disease in subjects switched from previous treatment with either Pramipexole or Ropinirole.
This research plan is focused on neurochemical positron emission tomography (PET) studies of Parkinson disease (PD). PD is the most common neurodegenerative movement disorder, and considerable progress has been made in understanding and treating the "typical" movement abnormalities of resting tremor, bradykinesia and rigidity. These cardinal PD features are all initially responsive to dopamine replacement therapy, and have been investigated intensively with respect to their relationships to degeneration of the nigrostriatal dopamine projection. More recently, increased attention has focused on the "non-motor" clinical aspects of PD, including cognitive, mood, chronobiological and peripheral autonomic defects. These clinical features are less reliably affected by dopaminergic therapy, and are likely to be associated with other, non-dopaminergic neural degenerations. Indeed, detailed postmortem assessments of PD brain reveal substantial neuronal losses in a variety of chemically-defined neurons, including brainstem serotonin and norepinephrine neurons and basal forebrain cholinergic neurons. Projects in the proposal will focus on dementia, depression, sleep-apnea and dysautonomia in PD patients, employing PET measures of presynaptic dopaminergic, serotoninergic and cholinergic CNS neurons and of peripheral sympathetic neurons. Results of the investigations may identify associations of non-motor PD signs and symptoms with the non-dopaminergic neuronal losses. These findings will establish additional therapeutic targets for symptomatic, but also for potential neuroprotective PD therapies. In addition, a majority of patients will be characterized with all 3 CNS PET measures. The availability of multiple markers of distinct neuronal populations involved in PD neurodegeneration will permit exploratory analyses to assess whether the degenerations are correlated (possibly manifestations of a common pathophysiology) or apparently independent (possibly a manifestation of multiple PD subtypes or pathophysiologies). Ultimately, better understanding of these non-motor features will be essential to developing future treatments that address the entire PD patient.
The primary purpose is to demonstrate superiority of Rotigotine over Placebo on motor symptoms when used in subjects with symptoms of Gastrointestinal Dysfunction. Hypothesis: Rotigotine will decrease OFF time compared to Placebo.
The purpose of this study is to evaluate if the antibiotic Ampicillin is safe and tolerated in patients that have generalized dystonia caused by the DYT-1 gene mutation, as compared to patients treated with a placebo. A placebo is a pill that looks and tastes the same as the real drug, but without the active ingredient. The second objective of this study is to determine if dystonia symptoms improve while on the study drug.
The purpose of this study is to evaluate the utility of a portable motion sensor-based system designed to assist with deep brain stimulation (DBS) programming sessions for Parkinson's disease patients.
To evaluate the effects of Memantine on non-motor symptoms in patients with Parkinson's disease. Parkinson's disease (PD) affects about one million people in the United States. It is a common neurological condition that is clinically defined by rigidity (muscle stiffness), bradykinesia (slowness of movement) and tremor. Parkinson's Disease , however, reveals numerous non-motor symptoms that have been underemphasized. Problematic symptoms include varying degrees of dementia, psychosis, diminished assertiveness and confidence, general fatigue, excessive daytime sleepiness, problems with blood pressure, sweating, and bladder, and a common yet difficult to define sense of "not feeling well".
The purpose of this study is to test the effects of carbidopa/levodopa/entacapone compared to the effects of immediate-release carbidopa/levodopa on non-motor symptoms of end-of-dose wearing off in persons who have Parkinson's disease.
To determine if PT intervention will be improved while in the "on" motor state vs. the "end-of-dose-off" motor state during the PT Intervention Visit in subjects with PD.
This study is designed to assess the effect of APOKYN treatment in rapid and reliable improvement of motor symptoms in Parkinson's disease (PD) subjects suffering from delayed or unreliable onset of levodopa (L-dopa) action.
This study seeks to establish the safety and efficacy of extended twice daily treatments for treating symptoms associated with PD. Only participants who completed the STEM-PD RCT trial are eligible for the OLE.

This study is a single-site, double-blinded, placebo-controlled, randomized clinical trial designed to elucidate mechanism(s) of action for symptomatic benefits observed in Parkinson's disease (PD) patients treating twice daily time-varying caloric vestibular stimulation treatment using a solid-state device. Study participants will self-administer treatments in the home setting over a period of 12 weeks. Changes in cerebral blood flow perfusion, cerebrovascular reactivity and functional connectivity between the pre-treatment baseline and the end of the treatment period will be monitored and will be compared to changes in validated standardized clinical measures of motor and non-motor symptoms in PD. The durability of effects will be evaluated at a post-treatment assessment conducted five weeks after treatment cessation.
This is a Phase IV, prospective, observational, post-marketing study designed to obtain additional data on the effect of XADAGO on motor and non-motor symptoms in Parkinson's Disease patients newly prescribed XADAGO.
This is a Phase 1/2a study to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of an orally-administered medication to relieve symptoms of constipation associated with Parkinson's Disease. Ten patients will be enrolled in Phase 1, and will be studied over an 8-12 week period. Forty patients will be enrolled in Phase 2, and will be studied over an 8-10 week period. All subjects will receive the study drug during one of the observational periods of the study.
The major purpose of the Stage 1 is to study the safety and tolerability of the proposed dosage regimen of the study drug. The form of cannabidiol (CBD) used in this study is GWP42003, supplied by GW Pharmaceuticals. The dosage regime is based on their experience. This is an open label study in 10 subjects, during which the dose is gradually increased to the manufacturers recommended target dose, with tolerability being evaluated at each dose level. Based on the response of subjects in the Stage 1, a target dose is determined for the next stage. Standardized tools will be administered to study both tolerability and efficacy. Efficacy assessments are simply explorative, and are done to look for an effect that warrants specific or different evaluation in the next stage.
This study is a non-interventional post-marketing observational study (PMOS) of participants with advanced Parkinson's disease (PD) treated with Duodopa/Duopa in a routine clinical setting. Effectiveness of treatment will be collected with physician and participant/caregiver health outcomes beginning with PMOS enrollment (baseline visit), at the start of Duodopa/Duopa treatment via percutaneous endoscopic gastrostomy-with jejunal extension (PEG-J), at regularly scheduled visits closest to Months 3 and 6, and every 6 months thereafter up to 36 months. An additional cohort of participants will be enrolled who in addition will be evaluated with a wearable device.
Exercise is often noted as an important component in a comprehensive approach to the management of Parkinson disease (PD). Most studies of exercise have examined the effects of short-term interventions and have tested participants on their anti-Parkinson medications. As such, these studies have not been able to determine whether or not exercise may have a disease-modifying effect in people with PD. The investigators recent work has shown the potential benefits of dance as a form of exercise for individuals with PD, but, like previous work, has only examined short-term interventions. The investigators think that dance may be ideally suited for study over a longer period of time because dance incorporates many of the features recommended for inclusion in PD-specific exercise programs in a format that is known to be engaging and to enhance motivation to participate in healthful behaviors. As such, the investigators aim to determine both the short- and long-term effectiveness of a community-based dance program for individuals with Parkinson disease and to determine how physical function changes over time in individuals with PD who do not exercise as compared to those who exercise regularly. The investigators hypothesize that: A) participation in dance will result in improved physical function, cognitive function, mood and quality of life in people with PD within 3 months, B) additional improvements will be noted at 6 months as compared to 3 months, C) improvements will be maintained at one year with continued, regular participation in a dance class, D) those who do not exercise will show significant functional decline over a period of one year, a decline that will not be present in those who dance regularly.
