Active clinical trials for "Multiple System Atrophy"

This project aims to investigate whether an integrated model based on proactive and reactive telenursing monitoring coordinated by a parkinsonism nurse specialist (case manager) is able to improve care delivery and quality of life of patients with atypical parkinsonisms. This could reduce the risk (e.g. through health education counselling) and the severity of complications (e.g. falls). Main responsibilities of the Co-PI: project idea and supervision, coordination of the study, patient selection and recruitment, patient recruitment, participation in statistical analysis and drafting the manuscript. Co-PI is responsible of the rate of recruitment and drop-out

Talisman is global clinical study (20058N) in Multiple System Atrophy (MSA) patients. It will be conducted in two regions (China and the European Union [EU]). There will be common study objectives between China and EU regions (including prospective assessments for MSA disease progression during routine clinical visits for MSA), and this will allow for data (on common objectives) to be presented overall and stratified by region. There will also be study objectives specific to each region: 1) the clinical assessment for MSA (Unified MSA Rating Scale [UMSARS]) has not been validated using standardised methods in China, and so the psychometric properties of the Chinese version of the UMSARS will be examined in Chinese patients in this study; 2) there will be retrospective assessments and prospective protocol-mandated assessments (of Magnetic Resonance Imaging [MRI] and bloods biomarkers) and study visits for EU patients. Because some study objectives are the same for China and the EU (i.e., prospective assessments during routine clinical visits for MSA), and other objectives are specific to each region, there will be one regional protocol for China and one regional protocol for the EU; each describing the study assessments relevant to each region.

The study purpose is conducting follow-up surveillance for the incidence of adverse events and efficacy of subjects participated in phase 1 trial to evaluate the safety and tolerability of autologous bone marrow-derived mesenchymal stem cells (CS10BR05) in subjects with Multiple System Atrophy until 60 months from administering investigational product (IP).

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

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.

The study is a multi-center, observational study to evaluate the feasibility of α-synuclein-related biomarkers and imaging data in the disease diagnosis and prognosis evaluation in Synucleinopathies and healthy subjects.

The purpose of this study was to determine whether Rifampicin was effective in slowing or reversing the progression of multiple system atrophy (MSA). Research studies indicate that there is an abnormality in protein synthesis and structure in parts of the brain responsible for MSA (protein misfolding) and the drug Rifampicin could potentially prevent or reverse this protein alteration. The study was done on participants with early MSA. The study consisted of taking the drug 2 times a day for 12 months. Participants underwent an evaluation of symptoms and function and will underwent a neurologic examination at the beginning of the study, at 6 months and at 12 months. They were also be contacted at 3 and 9 months by telephone. Studies were done at 10 participating sites.

NNIPPS is a clinical trial of riluzole (a drug previously shown to slow down the rate of progression og amyotrophic lateral sclerosis-ALS; Lou Gehrig's disease) involving nearly 800 people diagnosed with the 'parkinson plus' syndromes of multiple system atrophy (MSA) and progressive supranuclear plasy (PSP). In addition to showing whether riluzole is helpful in MSA and PSP, NNIPPS will improve criteria for making an accurate and early diagnosis, for assessing the rate of progression, and will advance understanding of the biology of these disabling and progressive neurodegenerative diseases.

This will be an observational study looking at clinical and biomarker characteristics in patients with Parkinson's Disease (PD), Multiple System Atrophy (MSA), Rapid Eye Movement Sleep Behavior Disorder (RBD), Normal Pressure Hydrocephalus and matched controls. Saliva, plasma, serum, urine, and cerebrospinal fluid (CSF) samples will be collected from participants.

Pharmacologic approaches to increase levels or actions of the vasodilatory peptide angiotensin-(1-7) are currently in development for the treatment of hypertension based on findings from animal models. There are limited and contradictory clinical studies, however, and it is not clear if this peptide regulates blood pressure in humans. The purpose of this study is to better understand the cardiovascular effects angiotensin-(1-7) in human hypertension, and to examine interactions of this peptide with the autonomic nervous system. The investigators propose that the difficulties in showing angiotensin-(1-7) cardiovascular effects in previous clinical studies relates to the buffering capacity of the baroreceptor reflex to prevent changes in blood pressure. Autonomic failure provides the ideal patient population to test this hypothesis. These patients have loss of baroreflex buffering and have low levels of angiotensin-(1-7) in blood. The investigators will test if angiotensin-(1-7) infusion can lower blood pressure in patients with autonomic failure, and will determine the hemodynamic and hormonal mechanisms involved in this effect.
