Multiple Sclerosis, Relapsing-Remitting

The clinical trial is intended to assess for clinical evidence of Clemastine Fumarate as a myelin repair therapy in patients with chronic inflammatory injury-causing demyelination as measured by multi-parametric MRI assessments. No reparative therapies exist for the treatment of multiple sclerosis. Clemastine fumarate was identified along with a series of other antimuscarinic medications as a potential remyelinating agent using the micropillar screen (BIMA) developed at the University of California, San Francisco (UCSF). Following in vivo validation, an FDA IND exemption was granted to investigate clemastine for the treatment of multiple sclerosis in the context of chronic optic neuropathy. That pilot study was recently completed and is the first randomized control trial documenting efficacy for a putative remyelinating agent for the treatment of MS. The preselected primary efficacy endpoint (visual evoked potential) was met and a strong trend to benefit was seen for the principal secondary endpoint assessing function (low contrast visual acuity). That trial number was 13-11577. This study seeks to follow up on that study and examine clemastine fumarate's protective and reparative effects in the context of chronic demyelinating brain lesions as imaged by multi-parametric MRI assessments. The investigators will be assessing the effects of clemastine fumarate as a remyelinating therapy and assessing its effect on MRI metrics of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis. In addition to using conventional multi-parametric MRI assessments, this study will also evaluate a new MRI technique called Ultrashort Echo Time (UTE) MRI to assess the effects of clemastine fumarate as a remyelinating therapy of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis and compare it to the other assessments.

The primary purpose of this interventional study is to examine the overall motor learning capacity from exposure to repeated perturbations among ambulatory people with multiple sclerosis (MS). This project will advance our understanding of learning new motor skills from exposure to external perturbations. If it is proven that people with MS can learn motor skills from perturbation training, the findings from this study will pave a theoretical foundation for applying perturbation training as a promising fall prevention intervention for people with MS.

The purpose of this study is to evaluate the effectiveness, safety, tolerability, drug levels and drug effects of ozanimod compared to fingolimod in children and adolescents with relapsing remitting multiple sclerosis (RRMS).

This study aims to understand the mechanisms of a novel intervention involving breathing short durations of low levels of oxygen for persons with multiple sclerosis (MS). This intervention with low levels of oxygen is called Acute Intermittent Hypoxia (AIH), the levels of oxygen experienced are similar to breathing the air on a tall mountain, for less than 1 minute at a time. Previous studies have shown that AIH is a safe and effective way to increase strength in persons with MS. Here the investigators aim to look at brain activation and ankle strength before and after AIH to gain a better understanding of how the AIH may improve strength in those persons with MS.

This study seeks to explore changes in the neural pathways and arm function following a breathing intervention in the multiple sclerosis (MS) population. The breathing intervention, known as Acute Intermittent Hypoxia (AIH), involves breathing brief bouts of low levels of oxygen. Research has found AIH to be a safe and effective intervention resulting in increased ankle strength in people with MS. Here, the study examines arm and hand function before and after AIH. In order to better understand the brain and spinal cord response to AIH, the investigators will measure muscle response, and signals sent from the brain to the arm muscles before and after AIH.

The goal of this clinical trial is to learn if repetitive Transcranial Magnetic Stimulation (rTMS) of the left premotor cortex can lessen fatigue in patients with Multiple Sclerosis, and if this is a feasible intervention. It will also give further information on fatigue in Multiple Sclerosis. The main questions it aims to answer is: * Does premotor rTMS decrease fatigue symptoms in patients with Multiple Sclerosis? * Is the change in fatigue reflected in an altered balance between brain excitation and inhibition in the targeted premotor cortex? Researchers will compare real rTMS with sham rTMS (which does not stimulate with a magnetic field), to see if real rTMS works to alleviate fatigue. Participants will: * Receive real or sham rTMS for 30 minutes, 5 days in a row * Visit the clinic before and 6 days after for baseline and follow-up * Fill out on-line questionnaires 1 day and 4 weeks after the end of intervention * Undergo a total of 3 brain scans (Magnetic Resonance Imaging at ultra-high field), at baseline, end of intervention, and follow-up * Undergo lab neurophysiological measurements before and after the first intervention session * Keep a fatigue diary and wear an activity tracker in the period before and after the intervention

The Clinnova-Multiple Sclerosis (MS) study is part of the Clinnova program (NCT06526364; NCT06235684 and NCT05733702), which seeks to advance precision medicine and the digitalization of healthcare through high-quality, interoperable health data. This program focuses on people with multiple sclerosis (MS) and aims to identify objective surrogate markers derived from clinical, epidemiological, imaging, and omics data that can predict disease activity, such as progression or relapses. By combining data science and artificial intelligence, the project seeks to improve patient stratification, support personalized therapeutic decisions, and provide insights into the mechanisms underlying treatment response and disease progression. Although many therapies are available for MS, it remains challenging to determine the most appropriate strategy for each patient and to prevent long-term disability. Current treatments mainly target relapses and inflammation, with limited effects on chronic progression. Clinnova-MS will collect and analyze real-world and research data to better understand variability in disease activity and treatment outcomes, enabling more precise, evidence-based care within the standard of care. This study represents the first step toward the broader Clinnova objective: developing sustainable, personalized, and preventive healthcare for people living with MS.

This prospective cohort study is part of the Clinnova programme and aims to (i) identify clinical imaging and omics characteristics associated with early Multiple Sclerosis (MS) and with transitioning phases to progressive MS, as well as (ii) to investigate digital biomarkers allowing the continuous clinical monitoring of those patients.

The prevalence of sexual dysfunction is higher among women with multiple sclerosis (MS) than women in the general population. The presence of sexual dysfunction is associated with decreased well-being and quality of life. There is limited research supporting pharmacological and other therapeutic approaches for managing sexual dysfunction in MS. Physical activity has beneficial effects on many of the consequences of MS, and physical activity represents a promising non-pharmacological approach for managing symptoms of sexual dysfunction in MS. The proposed research examines the effect of an Internet-delivered lifestyle physical activity intervention for improving sexual dysfunction in women with MS. The research proposed, if successful, will provide evidence for the efficacy of physical activity as a translatable approach for managing sexual dysfunction among women with MS.

The purpose of this research is to support the clinical value of the Cionic Neural Sleeve for individuals diagnosed with multiple sclerosis (MS).

The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., presupplementary motor area) thought to aid in memory will improve verbal retrieval in multiple sclerosis patients. The primary outcome measures are neuropsychological assessments of verbal retrieval, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures. Additionally, the study will examine the degree to which baseline assessments of cognition and concussion history predict responses to treatment over time, both on assessments administered within the intervention period and at follow-up.

Centra nervous system (CNF) damage in multiple sclerosis (MS), are mainly attributed to myelin destruction, axonal abnormalities and subsequent degeneration, and are responsible for serious deficiencies. Current therapies are focused on the treatment of inflammation with several types of anti-inflammatory agents. However, there is an urgent need for innovative therapies promoting neuroregeneration and particularly myelin repair. It has been demonstrated that testosterone can act through neural androgen receptors to promote proliferation and differentiation of oligodendrocyte precursors into mature oligodendrocytes in a cuprizone-induced animal model of demyelination. The rare clinical trials on testosterone are mainly exploratory. Here, we sought to demonstrate an effect of testosterone supplementation in testosterone-deficient patients in a multicenter, randomized, parallel-group, double-blind, placebo-controlled phase 2 trial. The main objective will be to determine the neuroprotective and remyelinating effects of testosterone using tensor diffusion imaging techniques and thalamic atrophy analyzes. As secondary objectives, we would like to study the impact of testosterone supplementation on other conventional and unconventional MRI parameters and on clinical outcomes (cognition, fatigue, quality of life, impact on work / activity and anxiety / depression).

Multiple sclerosis (MS) affects approximately 2.3 million patients worldwide, with a global median prevalence of 33 per 100,000. MS is diagnosed at an average of 30 years and affects twice as many women as men. MS is traditionally diagnosed by the presentation of lesions of the central nervous system, disseminated in time and in space, proven by clinical examination and magnetic resonance imaging. Several anatomical parameters in the eye, both vascular and neural, have been found to be altered in MS patients. Because of its unique optical properties, the eye offers the possibility of the non-invasive assessment of both structural and functional alterations in neuronal tissue. As the neuro-retina is part of the brain, it does not come as a surprise that neuro-degenerative changes in the brain are accompanied by structural and possibly also functional changes in the neuro-retina and the ocular vasculature. The current study seeks to test the hypothesis that beside the known anatomical changes, also functional changes can be detected in the retina of patients with MS. For this purpose, flicker light induced hyperemia will be measured in the retina as a functional test to assess the coupling between neural activity and blood flow. Further, structural parameters such as retinal nerve fiber layer thickness and function parameters such as ocular blood flow and retinal oxygenation will be assessed and compared to age and sex matched controls.

Multiple sclerosis (MS) is an inflammatory and immune-mediated neurological disease with multifactorial etiology. The specific etiopathogenetic mechanisms of MS are still unknown but it is clear that it results from a combination of genetic and environmental factors. Several studies have reported the possible role of diet as a risk factor for MS and its progression. To date, many dietary patterns and their association with MS have been studied, but data is still limited and inconclusive. Mediterranean Diet (MedDiet) has been associated with a lower risk of developing MS, compared to a Western-style diet. In one of investigators' studies, higher MedDiet adherence was associated with a 6-fold greater likelihood of having lower disease severity than those with low adherence. A significant restriction of carbohydrates (up to ketogenesis) can have beneficial effects on various parameters (inflammatory markers, oxidative stress, altered glucose metabolism) which are altered in subjects with MS. Ketogenic diet therapies (KDTs) have been recommended mainly for children with drug-resistant epilepsy, but in recent years they have been applied to Multiple Sclerosis. Preclinical studies in animal models evaluating the efficacy of KDTs in experimental autoimmune encephalomyelitis (EAE) found a beneficial effect of diet in slowing of disease progression, improvement of motor disability, reduction of inflammatory cytokines and reactive oxygen species. In a randomized study, improvements in health-related quality of life (HRQL) scores and a slight decrease in EDSS scores were found. An open-label, single-arm study of 20 patients with RRMS also reported that, after 6 months of MAD, no subjects had new or enlarging FLAIR/T2 lesions, with a significant improvement in the EDSS score, the Modified Fatigue Impact Scale subscales and arm. A 3-arm parallel-arm randomized controlled pilot study was planned to determine the effectiveness of a modified Atkins diet (MAD) compared to a Mediterranean diet (MedDiet) on quality of life in a population with MS.

The aim of this monocentric randomized controlled intervention study is to improve visual function in persons with multiple sclerosis following optic neuritis (neuritis nervi optici) by means of a light stimulation. In the treatment arm, two 80-second light stimulations are to be administered daily for 12 days in 25 persons with multiple sclerosis following recent optic neuritis (1-3 months). For the standardized application of light stimulation in the sense of standardized training, the light stimulation is to be carried out by watching a generated flicker video on a mobile phone. In a sham-intervened control group (sample size 25), the spontaneous course after optic neuritis will be recorded in parallel. Intensive neuronal stimulation of the visual pathway will be used to stimulate regenerative processes, which will be recorded by means of changes in high-contrast visual acuity (primary endpoint). Secondary endpoints are changes in a colored-contrast test, in 2.5% low contrast visual acuity, the peak conduction latency of visual evoked potentials, and retinal layer thicknesses and vessel densities measured in optical coherence tomography and optical coherence tomorgraphic angiography. These physiological parameters should help to understand the underlying processes of a potentially altered visual performance.

The goal of this observational study is to study the long-term effects of autologous hematopoietic stem cell transplantation (aHSCT) in people with highly active relapsing-remitting multiple sclerosis. The study will evaluate the following items: 1. Disease activity 2. Safety and tolerability of aHSCT 3. Changes in the immune system Participants will be subjected to frequent visits for five years after treatment with aHSCT. During these visits, clinical testing, evaluation by questionnaires, MRI scans and blood sampling will be performed.

The purpose of this study is to develop a measurement of walking quality, called Gait Deviation Index (GDI) for people with Multiple Sclerosis (MS).

This study is being conducted to investigate risk factors for disability progression in Multiple Sclerosis and related disorders (MSRD). The primary goal is to assess whether combining information from visual assessment, blood markers, as well as historical and ongoing longitudinal MRIs of the brain, orbit (the part of the skull where eyes are located), and/or spinal cord can predict changes in quantitative disability measures related to MSRD and neurological disease.

The underlying disease mechanisms which occur in patients with immune mediation neurological diseases, such as Multiple Sclerosis (MS), are incompletely understood. For such patients, autologous haematopoietic stem cell transplantation (aHSCT) has been increasingly used as a highly successful one-off treatment for some patients. This treatment aims to delete the faulty immune system with a course of chemotherapy and then 'reboot' the immune system using a patients' own stem cells (a cell with the unique ability of being a building block to create many different cells in the body) to stop further damage. Over the last 20 years more than 1800 patients with MS have been treated in Europe with high levels of success. It may be more successful than disease modifying treatment but unfortunately, a small portion of people do not respond to this treatment optimally and continue to accumulate disability. There is a risk of side effects, restricted largely to the time of treatment, which necessitates the need to ensure appropriate patients are treated. Whilst aHSCT is a very effective therapy, it is still in its early phase of development, is not in widespread use, and there is incomplete knowledge regarding how it works and importantly, why it does not work in some patients, and how to monitor response to treatment. Unfortunately, there is no way of detecting which patients will, and will not, benefit from the different treatments available or a way of monitoring the immune system to ensure further treatment is provided before irreversible damage occurs. This study will investigate the immune system which is found in the fluid surrounding the brain and spinal cord, blood and stool of patients undergoing aHSCT and compare it to those receiving disease modifying treatment. This study will therefore further the understanding of biomarkers of aHSCT to develop an awareness of how it can be refined, may improve monitoring of patients following treatment and permit the development of markers which can predict potential treatment success or failure before patients are exposed to the risks.

This prospective study combining non conventional MRI techniques, neuropsychological screening tools, and a neurophysiological work-up using a sensitive and validated battery, will evaluate the predictive value of these measures and will explore the changes of the cognitive scores from baseline.

Rationale: Ocrelizumab is widely and effectively used to treat relapsing multiple sclerosis (RMS). Phase II studies and data from large patient cohorts indicate that rituximab, another anti-CD20 monoclonal antibody, is probably equally effective and safe as ocrelizumab in the treatment of RMS. An advantage of rituximab is a considerably lower price. Therefore we will start a study aimed at demonstrating non-inferiority of rituximab compared to ocrelizumab in RMS. If non-inferiority of rituximab can be shown, important reductions in the cost of treatment of RMS will be possible, without loss of efficacy. Objective: Evaluating the efficacy and safety of ritixumab compared to ocrelizumab in the treatmens of RMS. Study design: Randomized double blind multi-centre non-inferiority study of rituximab compared to ocrelizumab in 200 patients with RMS. The trial duration will be 30 months Study population: The study population consists of 200 adult RMS patiens with an indication to start anti-CD20 monoclonal antibody treatment. Intervention: Patients will be randomized 1:1 into the standard group (ocrelizumab treatment) or the experimental group (rituximab treatment). Main study parameters: To conclude non-inferiority of rituximab there will be one primary endpoint: the proportion of patients free of inflammatory disease activity (defined as: new or enlarged T2 lesions) between week 24 (M6) and week 96 (M24) of treatment in each arm. Secondary trial endpoints are presence and number of clinical relapses,T2 and contrast enhancing lesion volumes, brain volume and brain volume changes, disease progression (defined as clinically relevant change on any of the measures: EDSS, T25FW, 9HPT, SDMT), biochemical parameters such as lipidomics and neurofilament light (NfL), immunological parameters, safety as measured by the number of (serious) adverse events ((S)AE), quality of life (EQ-5D-L) and treatment satisfaction (TSQM) and patient reported measures of MS impact (MSIS-29) and well-being (questionnaire on physical complaints) Nature and extent of the burden and risk: Patients included in this study will be treated and monitored by MRI, clinical tests and laboratory tests according to existing protocols and will not be exposed to extra or unknown risks. They will have extra annual questionnaires and larger blood samples at some time points. There is extensive experience with both rituximab and ocrelizumab as efficacious and safe treatments of RMS.
