Active clinical trials for "Multiple System Atrophy"

The researchers investigated the effectiveness and safety of BoNT/A injected into the detrusor muscle in patients with PD and MSA all of whom had detrusor muscle overactivity unresponsive to conventional medical therapy.

The aim of study is to investigate most effective site for control the motor coordination using transcranial direct current stimulation in multiple system atrophy with cerebellar feature

The prevalence of Multiple System Atrophy (MSA) is reported to be between 3.4 - 4.9 cases per 100,000 population. The estimated average incidence is 0.6 - 0.7 cases per 100,000 people per year. Many patients are not diagnosed properly during their lifetime because of the difficulty in differentiating MSA from other disorders. Approximately 29 - 33% of patients with isolated late onset cerebellar ataxia and 8 - 10% of patients with parkinsonism will develop MSA. There are currently no therapies that can cure or stop the progression of the disease. The current pharmacological therapy is only to relieve symptoms. Mesenchymal stem cells (MSC) are considered an efficient source of cells for therapy, because they can be safely harvested and transplanted to donors or patients, have low immunogenicity, and have broad therapeutic potential. Results from preliminary preclinical and clinical trials indicate the potential of MSC-based treatment in meeting several key aspects of neurodegeneration. Stem cell-based therapy for neurodegenerative diseases aims to stop clinical damage by regenerating and by providing local support for damaged tissue, in addition after transplantation, MSCs have been shown to be capable of penetrating the lesion area and thus have great potential use as a means of administering therapeutic agents. The subjects of this study were patients who experienced possible MSA based on the consensus clinical criteria for MSA. There will be three treatment groups with a total sample of 5 subjects each. Group 1 will receives MSC-Adipose Autologous with doses 2x50 million cells intratechally. Group 2 will receives MSC-Umbilical Cord Allogeneic with doses 2x 50 million cells intratechally. Group 3 will receives MSC-Umbilical Cord Allogeneic with doses 2x50 million cells intratechally and 2x10cc secretome MSC from Adipose Intravenously. Clinical improvement will be evaluated using the UMSARS scale, PET-Scans, MRI, DaTScan, IGF-1, BDNF, Sympathetic skin respons (SSR), EMG, Composite Autonomic Severity Score (CASS), High definition-Optical coherence tomography (HD-OCT), ERG, VEP, Log MAR chart, Ishihara test and side adverse effect on MSC. This study is divided into six timeframes : Before an implantation, First Month after second implantation, Third month after secondary implantation, Sixth month after second implantation, Ninth month after second implantation and Twelve month after second implantation. The differences between the test variables are then used as an indicator to assess clinical improvement within the subjects.

The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's disease.

The aim of this project is to develop an original biomarker for Parkinson's disease (PD) and other parkinsonian syndromes (multiple system atrophy and progressive supranuclear palsy) based upon the detection of pathological alpha-synuclein species in routine colonoscopic biopsies.

Parkinson's disease (PD) is the second most common neurodegenerative disease. Multiple system atrophy (MSA) is a relentlessly progressing rare neurodegenerative disease of unknown etiology. In early stages of the disease, PD and MSA symptoms are very similar, particularly MSA-P where Parkinsonism predominates. The differential diagnosis between MSA-P and PD can be very challenging in early disease stages, while early diagnostic certitude is important for the patient because of the diverging prognosis. Voice disorders are a common early symptom in both diseases and of different origin. The ambition and the originality of this project are to develop a digital voice-based tool for objective discrimination between PD and MSA-P.

In its simplest terms, obesity is the results of a positive balance between food intake and energy expenditure (EE). I.e., we take in more energy, in the form of food, than we expend, e.g., by exercise. In our sedentary society, resting EE accounts for most of total energy expenditure. The sympathetic nervous system (SNS, the one that produces adrenaline) is thought to contribute to resting EE. This conclusion is based on experiments where resting EE is decreased by beta-blockers, high blood pressure medicines that block only one aspect of the sympathetic nervous system. The investigators propose to use a different approach, by using a medication called trimethaphan that produces transient withdrawal of the autonomic nervous system. The investigators will then compare the measured resting EE before and after SNS withdraw and quantify the degree of contribution to the resting EE by the SNS and delineate differences between healthy normal, healthy obese, and patients with autonomic dysfunctions.

Based on previous promising results, the next step for the validation of a multimodal MRI method in diagnosis and follow up of patients reached by parkinsonian syndromes is (i) to test whether the multimodal neuroimaging is able to discriminate at the individual level, patients with multiple system atrophy parkinsonism (MSA) and patients with idiopathic Parkinson's disease (PD) (ii) to determine whether the method is sensitive to measure changes over time for the two diseases, according to imaging, neuropsychological and other clinical data. Patients will be compared with healthy controls.

The purpose of this study is to test the hypothesis that endothelin plays a role in the pathogenesis of supine hypertension in pure autonomic failure by increasing vascular resistance. To gauge its contribution to blood pressure regulation, pure autonomic failure and multiple system atrophy patients with supine hypertension will undergo a medication testing with the endothelin blocker, BQ123. We will compare the hemodynamic effects between PAF and MSA patients. Our primary endpoint will be the decrease in blood pressure during the administration of this compound.

This study seeks to establish the sensitivity and specificity of what appears to be a unique brainstem biomarker of Parkinson's Disease (PD) - an electrically induced olygosynaptic nasotrigeminal reflex response - in differentiating early stage PD from normal controls and from patients with various other neurodegenerative diseases. This study will additionally compare the biomarker to olfactory testing.
