Active clinical trials for "Multiple Sclerosis"

Approximately 65% of multiple sclerosis (MS) patients appear to have problems in their cognitive function. Long-term memory is one of the most frequently affected functions in MS patients. Many factors play a role in the deterioration of cognitive functions because of many symptoms of MS. The aim of this study is to investigate the relationship of cognitive function with physical factors such as balance, functional exercise capacity and personal factors such as fatigue level, mood, sleep quality in patients with MS.

Beyond white matter pathology, grey matter damage is considered as a key player in disability onset and progression in Multiple Sclerosis (MS). The underlying substratum of grey matter damage is complex and pluriform, ranging from cortical demyelinating lesions, synapse and dendrite disappearance to neuronal cell death. Current Magnetic Resonance Imaging MRI techniques fail to fully assess and quantify grey matter pathology in this disease. The development of a quantitative marker of neurodegeneration for MS patients would allow: (i) to better understand the pathophysiological mechanisms underlying the distinct forms of MS; (ii) to stratify patients according to their prognosis; and (iii) to evaluate new therapies aimed at promoting neuroprotection. would allow to better understand the mechanisms underlying the distinct forms of MS, to stratify patients according to their prognosis, and to evaluate new therapies aimed at promoting neuroprotection.

The methodology is a feasibility study to determine the feasibility of assessing people in the community with a neurological condition before proceeding towards a full powered community trial evaluating the influence of intrathecal baclofen.

This is a pilot study looking at the feasibility of a mobile application (app) to collect data from active tasks (questionnaires, 6Mapp™, COGapp™, VISapp™), clinical magnetic resonance imaging information and conduct genome-wide association studies in subjects with multiple sclerosis. Participants will be self-referred to this study from different sources; patient advocacy groups, social media tools, clinicaltrials.gov, and flyers.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) and is one of the most common neurological diseases, often leading to disability of the patients. The MS pathogenesis includes vascular and inflammatory components, however recently also the role of mitochondrial dysfunction being a hot topic in neurodegeneration.

Twenty subjects (10 patients and 10 age-matched control volunteers) will be recruited for this study. MRI scans will take place on a 3T MRI Scanner (Skyra or Prisma, Siemens Medical Solutions) located at The NYU Center for Biomedical Imaging. MRI scans will consist of a 1-hour brain scan for both patients and controls. In the first 6 months of the study, investigators will develop and test a uMT-based APT imaging for brain tissue pH measurement and use a hypercapnia paradigm to validate the tissue pH changes between breathing room air and 5% CO2 (by increasing tissue acidity) inhalation. With implementation of hypercapnia MRI, pH-weighted imaging will be validated for its robustness and reproducibility.

Using an automatic software tool, Pixyl.Neuro, to conduct a retrospective analysis (detection of lesions + segmentation of images + tracking over time) of cerebral MRI images acquired during a prospective study of patients presenting with clinically isolated syndrome, and comparing the results against manual analysis.

The objective of the study is to describe the current status of MS patients with urinary disorders in Lebanon, and to demonstrate whether invasive investigations improve the management of these patients compared to an optimal non-invasive approach.

Vaccines in MS patients have been controversial, in particular hepatitis B vaccine in the 90s and more recently human papillomavirus vaccine. There was an important flu incidence during the winter 2016-2017 that has revealed a low exposure to the flu vaccine in health professionals in France. Vaccine exposure of Multiple sclerosis (MS) patients has not been evaluated yet. Objectives The primary objective is to evaluate exposure to the flu vaccine in patients with MS during the 2016-17 campaign. Secondary objectives are to evaluate exposure to mandatory vaccines, non mandatory vaccines, in the context of immunoactive treatments; to identify potential limitations to vaccines in general in patients with MS. Methods Cross-sectional observational multicentric study, performed in Auvergne-Rhône-Alpes (France). Data will be collected through an auto-questionnaire administered during an out-patient visit or hospitalization, during a two-week period. Statistical analysis Description of the percentage of patients exposed to the flu vaccine, and to other vaccines. Stratification according to demographics (age, sex) and MS related criteria (disability level, relapse in the year before, disease-modifiying drug) Expected results Vaccine exposure of patients with MS will be put in perspective with the general population exposure. The study can provide information regarding potential reluctance of patients with MS towards vaccines. This could lead to develop specific communication tools for patients with MS and/or health professionals.

The main aim of the present study is to assess the prevalence, the topography and the clinical counterpart of cortical lesions in patient included early after the first clinical episode of multiple sclerosis. A second aim is to assess the direct contribution of cortical lesions - independent of WM injury - on the diffuse grey matter damage. Thirty MS patients will be included in the six months after the first clinical episode of multiple sclerosis for a monocentric transversal MRI study at 7T to assess cortical MS injury. Clinical (EDSS) and neuropsychological assessments will be performed in the population the same day of a multi-parametric MRI. MRI protocol is designed to increase the detection rate of CL using multiple contrasts at high isotropic resolution (600µm3) on a whole brain exploration. Thus, MRI acquisition will include MP2RAGE, T2*, FLAIR and DIR as previously published but also recent MRI technique like FLAWS, focusing on the grey matter by attenuating the white matter and CSF signal. Finally, QSM sequences will be performed. QSM measures tissue magnetic susceptibility mostly influenced by iron, myelin and calcium content in the brain. Due to physical properties of the technique (bipolarity), we suppose that high resolution QSM will be more sensitive that previous used sequences to depict cortical lesions. Using this multi-contrast approach with relevant MRI sequence and with a high resolution whole brain exploration might improve the detection of CL in early MS. Furthermore, MRI protocol allow us to estimate neuronal loss (T1 relaxation time), myelin and iron content (QSM and T2* relaxation time) within and outside cortical lesions in GM. The present study is an opportunity to assess cortical pathology in MS from the onset of the disease, allowing to a better understanding of its origins and its impact and disease severity. This study is a preliminary requirement to longitudinal studies to precisely depict the kinetic of cortical lesion accumulation and the links with disease aggravation.
