The study involves a two-arm, Phase 1, randomized controlled clinical trial designed to establish the feasibility and effects of a Functional Balance Intervention (FBI) on physical and cognitive function, as well as measures of daily living among persons with multiple sclerosis (PwMS). Combined Specific Aims: Aim 1: Examine the effect of the FBI (Intervention Group) on physical function in PwMS compared to a stretching program (Control Group). Hypothesis 1: After four months of training, the FBI group will show significantly greater improvements in physical function compared to the stretching group. Aim 2: Examine the effect of the multicomponent FBI on cognitive function in PwMS compared to the stretching program. Hypothesis 2: After four months of training, the FBI group will show significantly greater improvements in cognitive function compared to the stretching group. Aim 3: Examine the effects of the multicomponent FBI compared to the Control Group among PwMS on measures of daily living (dual-task performance, balance confidence, community mobility, and quality of life). Hypothesis 3: After four months of training, the FBI group will show significantly greater improvements in measures of daily living compared to the stretching group. All assessment sessions will be conducted virtually via Zoom. All measures collected during the initial screening, pre-training assessment, training progression, and mid- and post-training assessment sessions will be administered either via Zoom with a Helper Buddy present or through survey links sent to participants via the UIC REDCap system. The training sessions will be performed independently by the participants in the presence of a Helper Buddy. The investigators will recruit 75 people with multiple sclerosis (PwMS) for this study. Eligible participants will be randomized to either the FBI (Intervention) or stretching (Control) group, followed by an onboarding session with a designated Helper Buddy. Training will occur twice weekly for four months. Based on the anticipated attrition rate, the investigators aim for 40 PwMS to complete the post-training assessments and finish the study.

In this prospective, open-label, single-arm, single-institution trial, the investigators will accomplish the following two aims: 1. study the safety and tolerability of Ublituximab (Briumvi) twice annually in participants with early MS over a treatment observation period of \~12 months. 2. study the pre- and post-treatment change in plasma neurofilament light chain, tested at baseline pre-Ublituximab treatment, and q24 weeks for 96 weeks post Ublituximab treatment initiation.

The study is an investigator-run, study following participants for 2 years with twice-daily remibrutinib. MRI is the main endpoint. Safety, tolerability, and efficacy are secondary endpoints. Approximately 20 participants with relapsing or progressive forms of MS will be recruited.

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 goal of this clinical trial is to learn if drug CYB704, a proposed biosimilar to Ocrevus, works to treat multiple sclerosis in the same way as the reference product Ocrevus(R). The main questions it aims to answer are: * Is CYB704 distributed in the body in the same way as the reference product (demonstration of pharmacokinetic (PK) similarity)? * Does have CYB704 the same treatment effect and side effects as the reference product? Researchers will compare CYB704 to a Ocrevus (Ocrevus-US and Ocrevus-EU). Participants will: * Take drug CYB704 or Ocrevus (Ocrevus-US and Ocrevus-EU) * Visit the clinic for at least 15 treatment visits, checkups and tests * Will undergo regular magnetic resonance imaging (MRI) examinations

The purpose of this Phase 3b study is to assess the efficacy, safety and tolerability of remibrutinib after switching from ocrelizumab and compared to continuous ocrelizumab treatment, in patients living with relapsing multiple sclerosis (plwRMS).

The goal of this clinical trial is to learn if stimulating the vagus nerve in combination with a motor task in people with multiple sclerosis can improve motor function. The main questions it aims to answer are: * Is stimulating the vagus nerve safe and feasible after demyelinating episodes? * Does a paired motor task with vagus nerve stimulation improve motor function with someone who has multiple sclerosis? Researchers will compare active vagus nerve stimulation to a sham stimulation to see if the paired vagus nerve stimulation can improve motor control. Participants will: * Come in for study visits over a six month period. Study visits are three times weekly for the first month, then single follow up visits at two, three, and six months. * During study visits, participants will complete 30 minutes of the paired vagus nerve stimulation with a motor task, specifically the grooved peg test. * At various timepoints in the study, motor and disability tests will be administered to see if there are any changes in motor control for that participants. These tests include the timed 25 foot walk test, expanded disability scale, the upper extremity portion of the Fugl-Meyer Assessment, and the Multiple Sclerosis Impact Scale - 29.

The purpose of this study is to test if ublituximab changes walking functions and fall risk in people with relapsing multiple sclerosis (RMS). Twenty-five qualified people with RMS will undergo a 48-week ublituximab treatment. Before, 24 weeks into, and after the treatment, their ambulatory function, disability status, and cognition will be assessed. Additionally, they will experience large-scale slip perturbations on a treadmill under the protection of a safety harness at the last assessment. The outcome measures will be compared across the assessments to examine the effects of ublituximab on improving their walking function, disability status, cognition, and the responses to the unexpected slip perturbation.

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 \[EFC16035\]). SUBSTUDY: ToleDYNAMIC substudy

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.

The primary purpose of this phase 3b study is to assess the efficacy of a modified regimen of ublituximab as measured by T1 Gadolinium (Gd)-enhancing lesions and pharmacokinetics in participants with Relapsing Multiple Sclerosis (RMS). The study consists of 2 parts: Part A is single-armed and open-label and Part B is randomized, double-blind, placebo-controlled.

This trial compares two medications, remibrutinib and teriflunomide, for treating patients with relapsing multiple sclerosis. These patients have repeated episodes of symptoms and need effective treatments. The medications work by controlling the immune system to prevent it from causing damage to the nervous system. Teriflunomide is an approved medication for adults with relapsing multiple sclerosis.
