The purpose of this trial is to compare the treatment strategy of Autologous Hematopoietic Stem Cell Transplantation (AHSCT) to the treatment strategy of Best Available Therapy (BAT) for treatment-resistant relapsing multiple sclerosis (MS). Participants will be randomized at a 1 to 1 (1:1) ratio. All participants will be followed for 72 months after randomization (Day 0, Visit 0).

The purpose of this study is to compare the effectiveness and safety of ofatumumab given by injection every 4 weeks, compared to teriflunomide given orally once daily to patients who have relapsing type (returns and worsens unpredictably) multiple sclerosis.

The hallmark of MS is white matter lesion formation. However, there is increased evidence for gray matter (cortical) involvement and we hypothesize that these cortical lesions are present in patients even in early MS, and may directly determine the location of white matter lesion formation, as well as contribute to cognitive dysfunction in MS. Double inversion recovery (DIR) MRI sequences have been described in multiple adult multiple sclerosis studies to be sensitive for cortical lesions. These images can be obtained on 3 Tesla MRI scanners, using a non-invasive protocol that has been in place at Mayo Clinic. If such cortical ...

The study is designed to quantitate McArdle's sign, an increase in measurable weakness with neck flexion described in patients with multiple sclerosis, and to determine whether it is or is not specific for multiple sclerosis.

This is a Phase 3 extension, global, multicenter study to assess the long-term safety and tolerability of tolebrutinib in adult participants (aged ≥18 years) with RMS, PPMS, or NRSPMS who were previously enrolled in the Phase 2b LTS (LTS16004) or 1 of the 4 Phase 3 tolebrutinib pivotal trials (GEMINI 1 \[EFC16033\], GEMINI 2 \[EFC16034\], HERCULES \[EFC16645\], or PERSEUS \[EFC16035\]).

The purpose of this study is to gain an understanding of the progressive multiple sclerosis (MS) experience and the meaning patients bring to the experience. By learning about the specific care gaps, barriers, and overall scope of burden, we hope to assess how telemedicine may be effectively used to improve the patient experience and management of progressive MS. 

The primary aim of this project is to utilize commercial-grade wearable devices to develop the SMART (Self-Monitoring and Advanced Registry Technology) platform to enhance the monitoring and management of multiple sclerosis (MS) and neuroimmunological disorders.

This study aims to determine the efficacy of SAR442168 compared to placebo in delaying disability progression in NRSPMS and on clinical endpoints, MRI lesions, cognitive performance, physical function, and quality of life.

The purpose of this study is to determine clinical outcome following treatment for multiple sclerosis (MS) relapse, in patients who were seen at Mayo Clinic.

The purpose of this study is to evaluate, jointly and independently among patients deemed at higher risk vs. lower risk for disability accumulation, whether an "early aggressive" therapy approach, versus starting with a traditional, first-line therapy, influences the intermediate-term risk of disability, and to evaluate if, among patients deemed at lower risk for disability who start on first-line MS therapies but experience breakthrough disease, those who switch to a higher-efficacy versus a new first-line therapy have different intermediate-term risk of disability.FDA-approved multiple sclerosis (MS) disease-modifying therapies (DMTs) target the relapsing phase of MS but have minimal impact once the progressive phase has ...

The purpose of this study is to compare the effectiveness of 7T imaging to the current conventional imaging (3T) to improve MR sensitivity to the changes of multiple sclerosis.  Using FDA-cleared 7T imaging would have a substantial impact on patient management.

The purpose of this study is to determine the effectiveness and safety of ofatumumab and siponimod compared to fingolimod in pediatric patients with multiple sclerosis.

The purpose of this study is to determine whether an EHT approach to DMT, defined as use of one of five monoclonal antibodies (alemtuzumab, natalizumab, rituximab, ocrelizumab, ofatumumab) as first-line therapy, is more effective than an escalation of treatment approach in reducing normalized whole brain volume loss measured using MRI in PwRRMS from Baseline to Month 36.

Multi-center pragmatic comparative effectiveness randomized clinical trial with additional-parallel observational cohort.
The DELIVER-MS study seeks to answer the important question: Does early treatment with highly effective DMT improve the prognosis for people with MS? This is an area of significant controversy and no data ...

This open-label, rater-blinded extension study will enroll patients who have relapsing-remitting multiple sclerosis (RRMS) and who participated in one of three prior Genzyme-sponsored studies of alemtuzumab [CAMMS223 (NCT00050778), CAMMS323 (NCT00530348) also known as CARE-MS I, or CAMMS324 (NCT00548405) also known as CARE-MS II].

The purposes of this study are:

1. To examine the long term safety and efficacy of alemtuzumab treatment in patients who received alemtuzumab as their study treatment in one of the prior studies.

2. To examine the safety and efficacy of initial alemtuzumab treatment in this study for patients who received Rebif® (interferon beta-1a) ...

The purpose of this study is to develop quantitative approaches of analyzing multimodal MRI acquisitions with the goal to improve cortical lesion detection in all stages in MS, and to understand the interplay between cortical lesions, white matter lesions and functional connectivity network disruptions.

The purposes of this study are to explore the association between female sex, reproductive history and clinical phenotypic variability in multiple sclerosis (MS), to explore the association between female sex, reproductive history and radiologic phenotypic variability in MS, and to explore the association between female sex, genetic and environmental interactions in MS.

The purpose of this study is to evaluate the long-term safety, effectiveness, and patient reported quality of life outcomes of treatment with alemtuzumab for patients who have multiple sclerosis and participated in a previous study of alemtuzumab.

The purpose of this study is to better identify the long term benefit to risk profile of tecfidera in patients with multiple sclerosis who are prescribed tecfidera under routine clinical care.

The aims of this study are:

• To assess the prevalence of episodic hypothermia among multiple sclerosis (MS) patients evaluated at Mayo Clinic.

• To characterize clinical, radiographic, and laboratory features of patients with MS-related hypothermia.

The purpose of this research is to better understand brain white matter hyperintensities (WMH) in women with migraine. We will accomplish this by comparing brain imaging and clinical assessments of women with migraine, small vessel ischemic (SVI) disease, and multiple sclerosis (MS).

The purpose of this study is to establish a repository consisting of clinical information, radiological data, serum, peripheral blood lymphocytes, plasma, cerebrospinal fluid (CSF), urine, stool, DNA and tissue specimens collected from patients who have central nervous system (CNS)  inflammatory diseases. 

The aim is to establish a repository consisting of clinical information, radiological data, serum, peripheral blood lymphocytes, plasma, cerebrospinal fluid (CSF), and tissue specimens collected prospectively from patients with CNS diseases and controls.
