Active clinical trials for "Parkinson Disease"

This is a multicenter study to evaluate the safety and clinical outcomes of BRT-DA01 in subjects with PD who previously received BRT-DA01 in the Phase 1 Study MSK-DA01-101.No investigational therapy will be administered in this study.

The aim of this research is to verify the ability of counterfactual thinking about medical decisions in individuals affected by Parkinson's Disease when compared to healthy individuals.

The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Parkinson's disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and/or store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for Parkinson's disease.

This is a multicentre, prospective international observational study. Male patients in the UK, USA and France performing self-catheterisation will be asked to participate in this study. The subjects will be asked to use the GentleCath™ Intermittent Catheter with FeelClean™ Technology as per their normal routine. They will be asked to record when and where they catheterise. At the baseline, during and on completion of the study, the subjects will be asked to complete Difficulty in Catheterisation plus Intermittent Catheter related Quality of Life Questionnaires. Difficulty during catheterisation and quality of life will be assessed using the ICDQ and ISC-Q validated questionnaires during catheterisation at the start of the study before use of GentleCath™ Air has commenced (D0) and on day 1 (D1), day 15 (D15), day 30 (D30), day 45 (D45) and day 60 (D60) transcribed in a collecting record provided for this purpose. Compliance and catheter use will also be assessed. Patient confidence regarding reduced stickiness plus related risk of urethral injury and resultant bleeding or infection will also be recorded.

The investigators have recently discovered a metabolic biomarker which predicts Parkinson's disease (PD) at the early stages in patients and in animal models. The aim of BIOPARK is to investigate how the biomarker evolves in advanced PD stage, when diagnosis confirmation is higher, an in de novo PD patients who come from a different geographical area than those of the publication (since it is known that the metabolome is largely influenced by lifestyle). They will also evaluate if the biomarker is able to distinguish patients with a parkinsonian syndrome often confused with parkinson's disease, i.e. Multiple System Atrophy (MSA).

Background: A movement disorder is a condition that causes a person s body to move in ways that are not normal. There are different types. Some disorders cause movements people can t control, such as tics or shaking. Some cause reduced or slow movements. Movement disorders can cause disability in people. Sometimes members of the same family will have the same disorder. Researchers want to learn more about how people develop these disorders. This research could lead to better treatments. Objective: This natural history study will collect data on people with different types of movement disorders. It will also collect data on their family members. The data will support further research. Eligibility: Children and adults aged 2 years and older who have a movement disorder. Family members of people with movement disorders are also needed. Design: Participants will undergo screening. They will have a physical exam. Researchers will look at their existing medical images. Any photographs or videos of their movements will also be reviewed. Most participants will come to the NIH clinic for only 1 visit. They will answer questions about their condition. They will have normal tests used to diagnose their condition. They may have blood tests and different types of imaging scans. They may have tests to see how well their nerves function. The tests used will depend on the type of disorder they have. Family members will have some of the same tests as people with disorders. Participants will not receive any new treatments. Some participants may be asked to return for a follow-up visit. Up to 4000 people may participate.

The primary aim of this study is to compare maximum and functional exercise capacity and muscle oxygenation during exercise test in patients with Parkinson's disease. The secondary aim is to evaluate respiratory functions, respiratory muscle strength and endurance, peripheral muscle strength, physical activity level, shortness of breath and fatigue in Parkinson's patients and compare with healthy individuals.

In this study, the researchers aim to find a biomarker of PD. Using imaging scans called Positron Emission tomography (PET), Single Photon Emission Computed Tomography (SPECT), and Magnetic Resonance Imaging (MRI). The PET and SPECT scans use small amounts of radiation and specific compounds called tracers, to study chemical changes in the brain in a way not possible with any other procedure. The MRI uses magnetic fields to generate images of brain structure and function

The clinical management of Parkinson's disease (PD) is frequently challenged by the occurrence of motor disorders and complications, such as freezing of gait, fluctuations and the ON-OFF phenomenon, primarily manifesting at home. Therapeutic decisions are usually based on periodic neurological examinations and patients' anamnestic experience collected in an outpatient setting, thus limited by several issues, including "recall bias" and subjective, semi-quantitative and operator-dependent evaluations in non-ecological settings. In the last two decades, new wearable technologies, consisting of "wireless" sensors (e.g., inertial, electromyography), have been widely applied to quantitatively assess movements in physiological and pathological conditions, even for prolonged periods in free-living settings (i.e., long-term monitoring). The aim of this study is to evaluate motor symptoms in patients with PD, such as bradykinesia, tremor, gait disturbances and balance disorders, objectively and quantitatively through the application of wearable sensors in intra- and extra hospital settings, also during common activities of daily living, in order to obtain ecological data possibly useful in the therapeutic management of the disease.

REM sleep behavior disorder is a novel and distinct parasomnia characterized by recurrent dream enactment behaviors (DEBs) and polysomnographic features of REM sleep without atonia (RSWA), with typical onset age at early 60's. Idiopathic RBD (iRBD) has been suggested as a most specific precursor of α-synucleinopathy-related neurodegeneration (e.g. Parkinson's disease (PD)). There are increasing reports of positive familial cases in both iRBD and PD. In the past few years, the investigators have established the baseline data of a case-control family cohort of iRBD (208 first-degree relatives (FDR) of patients with iRBD and 204 FDRs of controls). Not only did the investigators confirm the familial aggregation of iRBD with neurodegeneration and iRBD cases, the investigator also found that the FDRs harbored a spectrum of isolated RBD features (including DEBs, REM- sleep behavioral events, and RSWA). Besides, when compared with control-FDRs, iRBD-FDRs patients showed more prodromal markers of neurodegeneration (including possible/probable RBD, excessive daytime sleepiness, constipation, and subthreshold parkinsonism) as suggested by the International Parkinson and Movement Disorder Society (MDS) research criteria. The promising baseline findings paved the way for the current proposed prospective study of this unique family cohort. In addition, around 85 unaffected FDRs from each group has repeated the assessments at a mean follow-up duration of about 4 years (early termination of the study supported by RGC- ECS Ref no. 24117018; reason for early termination - ECS PI applicant left the University at early 2020), the preliminary data indicated a persistent familial aggregation of RBD symptoms, loading of prodromal markers (e.g. possible RBD, subthreshold parkinsonism), and a seemingly faster progression into prodromal RBD among the FDRs of iRBD than that of control. This current proposed study is a prospective study with a mean of 7-year follow-up interval to monitor the progression of α- synucleinopathy neurodegeneration and related markers. With the rolling recruitment, the investigators now have 230 control-FDRs and 250 iRBD-FDRs, from which the investigators expect 200 FDRs of each group may respond to the follow-up study. A series of prodromal markers related to neurodegeneration including clinical and sleep assessment (e.g. autonomic symptoms, motor signs, neurocognitive function, sleepiness, vPSG and one-week actigraphy) that were measured at baseline will be reassessed. Specifically, home PSG with a body-movement monitoring system will be additionally implemented in the proposed study to empower the identification of RBD features, especially during the COVID pandemic period at which hospital accessibility is restricted. In addition, the development of clinical neurodegenerative diseases will be ascertained. This proposed study, by recruiting FDRs of iRBD patients (and controls) with prospective study design, will provide novel and important information on the progression of prodromal makers of α-synucleinopathy neurodegenerative diseases in a high-risk population and facilitate further genetic/omics and future neuroprotective intervention study of the familial iRBD.
