Active clinical trials for "Multiple Sclerosis, Relapsing-Remitting"

In this Phase 1b open-label prospective clinical trial, patients with relapsing-remitting MS will undergo FMT of FMP30 (donor stool) via colonoscopy and immunological efficacy endpoints will be assessed at various time points. The active phase of the study will continue for 12 weeks post-FMT with safety and biomarker (engraftment) follow-up for 48 weeks. A parallel observational control arm of MS patients who otherwise satisfy study inclusion criteria based on their MS phenotype, demographics, disease duration and prior use of allowable MS therapies, will be recruited as a comparison observational group to measure stability of stool and serum immunological measures. The study duration for the Observational Control Arm is 12 weeks.

B-cells have an important role in the pathogenesis of multiple sclerosis (MS). Ocrelizumab, a medication that targets B-cells have been found to be highly effective in stopping the disease activity in relapsing-remitting MS. The efficacy of ocrelizumab might be related to the specific pattern of B-cell tolerance defect in patients with MS and the potential of its normalization with treatment with ocrelizumab. By analyzing the reactivity of recombinant antibodies expressed from single B-cells, the investigators' collaborators have demonstrated that the pattern of B-cell tolerance defect is different in people with MS who only display an impaired removal of developing autoreactive B-cells in the periphery while central B-cell tolerance in the bone marrow is functional in most patients. In contrast, patients with rheumatoid arthritis (RA), type-1 diabetes (T1D) or Sjögren's syndrome (SS) show defective central and peripheral B-cell tolerance checkpoints. As a consequence, while anti-B-cell therapy does not correct defective early B-cell tolerance checkpoints in T1D and only temporarily slows down autoimmune processes before newly generated autoreactive B-cells likely induce patient relapse, the investigators postulate that the efficacy of ocrelizumab in MS may be linked to normal central B-cell tolerance and the production of a normal B-cell and T-cell compartment after ocrelizumab therapy. In an open-label study, 10 patients with relapsing MS will be treated with two courses of ocrelizumab and will be followed clinically and radiologically for at least two and a half years. Assessment of T and B-cell phenotypes and function at baseline and 18-24 months post-B-cell depletion will be the primary outcome of the study.

The aim of this protocol is to find out about the safety and effectiveness of M2951 in participants with relapsing multiple sclerosis. Participants were placed into 1 of 3 groups to receive M2951, placebo or tecfidera for 24 weeks. After 24 weeks, the participants on placebo were given M2951.

This is a phase IIa study in which GA Depot 80 or 40mg is administered as an IM injection to subjects with RRMS at 4 week intervals for 52 weeks of treatment. The purpose of the study is to assess safety, tolerability, and efficacy of a monthly long-acting IM injection of 80 or 40mg GA Depot in subjects with RRMS. The study will include subjects switching from daily or thrice weekly administration of 20 mg or 40mg respectively of glatiramer acetate (GA, i.e., Copaxone®) injection

Multiple sclerosis (MS) is a chronic, immune-mediated, demyelinating disease of the central nervous system. Typical brain lesions of the disease may be partially repaired by an endogenous remyelination process which is limited and tends to deplete over the course of the disease. Cladribine tablets are an approved treatment that promotes selective lymphocyte depletion, reducing the inflammatory activity of the disease. The present study is based on the hypothesis that improved inflammatory control through cladribine tablets provides a tissue microenvironment more favorable for remyelination of brain lesions in MS. This hypothesis will be evaluated by a single-arm, open-label, phase IV, single-center, proof-of-concept clinical trial in which 10 participants with relapsing-remitting, highly active MS, relatively early in the course of the disease, will receive conventional treatment with cladribine tablets and will be followed-up for 48 months. Neurological, neuropsychological and magnetic resonance imaging (MRI) parameters will be measured. Remyelination will be assessed by a novel MRI technique called the q-Space myelin map. Additionally, the peripheral blood lymphocyte and cytokine profiles will be evaluated in order to understand the immunological aspects that influence the remyelination capacity in patients treated with cladribine tablets. The study will be conducted in accordance with current regulations governing clinical research in Brazil.

A randomized trial of long-term dosage of rituximab in multiple sclerosis

The purpose of this research study is to investigate the effectiveness of Tysabri 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.

The investigators intend to examine the effects of ocrelizumab use in African American multiple sclerosis disease course compared to Caucasian disease course utilizing imaging measures with magnetic resonance imaging (MRI) and optical coherence tomography angiography (OCT-A)..

Multiple Sclerosis (MS) is the most common acquired neurological disease leading to disability, especially ambulatory, in young adults. To date, the correlation between the number or volume of white matter lesions seen on conventional MRI and the degree of disability of patients remains low to moderate. This phenomenon is known as the "clinical-radiological paradox". In this new project, we hypothesize that an evaluation of the corticospinal pathways including their thoracic medullary portion, as well as taking into account the severity of the lesions using quantitative MRI, will allow the investigators to refine the correlation with ambulatory disability in MS patients. We will complete the evaluation of motor pathways with those of the proprioceptive pathways also strongly involved in ambulation.

This study aims to develop and validate a sensitive and non-invasive eye-tracking software application. This study will obtain participant responses to brief cognitive tests designed to evaluate several key functions known to be affected by CIS and RRMS and non-invasive eye movement measurements in response to visually presented stimuli during specifically designed eye-tracking tests. The study data will be used to develop machine learning algorithms and validate a software application intended to identify which metrics-or combination thereof-can serve as reliable biomarker of CIS and RRMS disease progression and cognitive status.
