Active clinical trials for "Multiple Sclerosis"

The central hypothesis of this protocol is that it is possible, using First Degree Relatives (FDRs) of patients with Multiple Sclerosis (MS) and assessing a variety of both known and unknown risk factors for MS, to define a risk algorithm for earliest signs of development of MS. The plan will be to do an abbreviated brain Magnetic Resonance Imaging (MRI) scan in asymptomatic, young FDRs, analyze blood for a variety of immunological, genetic, neuroaxonal damage, metabolic, viral serology and other markers, and have FDRs fill out a detailed bioscreen questionnaire about lifestyle factors and perform a cognitive screening test. The investigators will then compare the results of the various blood/other studies in FDRs with and without an MRI showing signs signs concerning for MS, as well as age-and sex-matched NON-FDRs who will have blood drawn and fill out the questionnaire. With this preliminary cross-sectional study, the investigators hope to begin to identify a risk stratification model for those at highest risk of developing MS, ie FDRs, with a long-term goal of developing a longitudinal study to increase sensitivity and specificity of the risk model.

Although the orofacial pain is not typical symptom of multiple sclerosis, more than 50% of the patients experience some kind of pain. Acute pain usually in form of trigeminal neuralgia, that occurred in 2-3% of patients with multiple sclerosis. Chronic pain occurred in 40-50% of patients and most common forms are headache. Aim of this study is to investigate prevalence and evaluate the form of orofacial pain in patients with multiple sclerosis treated in General hospital Varaždin in period from 01.01. 2017. to 31.12.2022. Results of this investigation will determine better understanding orofacial pain , treatment and impact on everyday life.

The purpose of this study is to investigate the immune cell and other factor changes with Ocrevus in Multiple Sclerosis (MS) patients. Researchers will recruit 35 participants for this study. Patients will be enrolled from the Multiple Sclerosis Center at the University of Michigan Health System in Ann Arbor. The goal of the study is to understand the role of regulatory B cell, T cell and other factors in mediating the therapeutic effects of Ocrevus.

The purpose of this research study is to investigate the effectiveness of MS Disease modifying medications on cognitive fatigue in persons with relapsing remitting multiple sclerosis (RRMS). Cognitive fatigue is the kind of fatigue that occurs after intense mental concentration as after a session of problem solving.

To determine if biomarker-based CSF testing is reliably detecting differences between patients with Multiple Sclerosis (MS), different MS-subtypes, and other central nervous system (CNS) diseases. This study will also look to identify biomarkers that could be used for the prediction, at the time of diagnosis, of the future disease clinical course and response to therapy. The SOMAscan assay will be used for CSF samples analysis.

Progressive-onset multiple sclerosis (PPMS) occurs in about 15% of all people living with MS. PPMS remains understudied, and most disease-modifying treatments are ineffective for PPMS. To date, it is unknown why some people progress immediately from MS onset. The present study will assess the role of gray matter in PPMS by characterizing it with ultra-high field magnetic resonance imaging (MRI). While both white and gray matter are affected in relapsing MS, in PPMS tissue damage is primarily in the cortex. Cortical gray matter consists largely of neuronal cell bodies, which send electrical signals to create a functional response, such as arm or leg movement. While white matter damage slows the signal response, cortical damage inhibits the initial creation of electrical signals. There is a great need to research and develop scientific biomarkers to identify and monitor progression and repair in PPMS. In this project, 7 Tesla MRI is used to investigate the cortical gray matter in people with PPMS. 7 Tesla MRI is the safest and most detailed way to study the brain. Because the cortex is only a few millimeters thick, it has been traditionally difficult to investigate. At 7 Tesla, different layers and lesions within the cortex can be seen. In addition, this project will use myelin-sensitive MRI to determine the biological underpinnings of both cortical lesions and the 'normal appearing' cortical damage in PPMS. This will answer relevant questions about the brain's capacity for repair, the extent of demyelination and the occurrence of inherent cortical remyelination and provides an avenue for the development of novel clinical MR biomarkers tailored to PPMS.

Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) causing focal lesions of demyelination and diffuse neurodegeneration in the grey and white matter of the brain and spinal cord, leading to physical and cognitive disability. The scientific community and patients are in need for new and more reliable biomarkers, especially biomarkers of disease progression in order to adapt therapeutic approaches on an individual level. Digital biomarkers have the potential to fill this gap allowing for quasi-continuous measures that might be more informative than episodically collected conventional data concerning the impact of the disease on activities of daily living. Using app-based challenges, continuous monitoring and surveys the Investigators aim to obtain data that can be used as digital biomarkers (DB). These digital biomarkers will provide more granular and precise assessments, thus complementing traditional diagnostic measures and techniques. After a first feasibility study (ClinicalTrials.gov: NCT04413032) a number of digital biomarkers have been identified as reliable, reproducible and meaningful to PwMS and are therefore being validated in a bigger cohort of PwMS with a longer follow-up within this validation study 1. Those digital biomarkers will be compared to state-of-the-Art clinical, imaging and body fluid assessment.

Transcranial magnetic stimulation (TMS) studies reported consistent and substantial impairments in the central nervous system (CNS) in multiple sclerosis (MS). Studies of peripheral nervous system (PNS) function comprising electromyoneurography (EMNG) reported impairments of the PNS in MS that were less pronounced and inconsistent. Neurophysiological studies are generally small and cross-sectional and with the poor grouping of MS patients according to MS type. The objective of the study is to investigate clinical, neurophysiological, and immunological markers in relapsing-remitting MS patients, and in patients with relapsing-remitting MS treated with immunomodulation. The results of the study may contribute to a better understanding of the pathophysiology of multiple sclerosis and can provide guidance in the diagnosis and treatment of patients with relapsing-remitting MS.

The purpose of the study is to determine the effects of testosterone treatment on erectile function, fatigue, depression, cognitive function, quality of life, urinary incontinence, pain, and damage to neurons in male Multiple Sclerosis patients with low testosterone, using questionnaires, blood samples and a rectal exam in volunteers 55 years and older.

The purpose of the research study is to identify the genetic, environmental and immune profiles that may increase a person's risk of developing multiple sclerosis (MS). While MS is not a disease caused by a single variation in genetic material (DNA), a single environmental factor, or a single malfunction in immune cells, there are genetic alterations, environmental exposures and immunologic factors that make the development of MS more likely. Obtaining information about who is at risk for MS will be beneficial in the future if the investigators can identify effective ways to prevent or slow down the progression of this disease.
