  1. Clinical Trial: Treatment Strategies to Prevent Disability

    A study based at Johns Hopkins University is comparing two treatment strategies in 900 people newly diagnosed, or with onset/diagnosis in the past who have received minimal or no treatment, with the relapsing-remitting form of MS. The study is recruiting at approximately 45 ce...
  2. Clinical Trial: Tai Chi and Mindfulness Training

    Investigators are recruiting people with all subtypes of MS (participants need to capable of standing and moving unaided for a minimum of 15 minutes at a time) to investigate the impact of mindfulness training on balance and wellbeing in individuals with MS. This is a communit...
  3. Clinical Trial: Gut bacteria and MS

    The Yale-Griffin Prevention Research Center, the Multiple Sclerosis Treatment Center at Griffin Hospital, and Yale University are teaming up to study whether changing the bacteria in the gut can affect the process that leads to the development of multiple sclerosis (MS). This ...
  4. Clinical Trial: Pathological Basis of MRI Signal Changes in Multiple Sclerosis

    Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about the stages of multiple sclerosis and follow...
  5. Research Study: Seeking first degree relatives of people with MS for study of risk factors

    The goal of this study is to learn more about the causes of and risk factors for MS by studying first-degree relatives of people with MS and comparing them to people who are not first-degree relatives of someone with MS. We will use the data collected to develop a risk algorit...
  6. Clinical Trial: Computerized Cognitive Training

    The purpose of this study is to evaluate two computerized brain training tools, which include light physical activity, to see if they can help improve cognitive functions, such as memory and attention, for people with MS. Participants would complete a set of tests (physical an...
  7. Clinical Trial: Ocrelizumab in Adults With Primary Progressive Multiple Sclerosis

    This study will evaluate the effectiveness and safety of ocrelizumab ( Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study focuses on upper limit disability progres...
  8. Research Study: International MS Microbiome Study

    This study aims to understand the role of gut bacteria in MS, and by extension allows us to look at the effects of diet and environment on the gut microbiome and MS disease susceptibility and progression. For this study, we are asking that participants donate blood and stool ...
  9. Research Study: cognitive testing for MS

    Researchers are currently enrolling participants in a study of cognitive testing for Multiple Sclerosis. This study compares computerized and in-person cognitive testing, to see how well the results match. Participants will complete assessments of sensory, motor, and cognitive...
  10. Clinical Trial: Cognitive Processing Speed Changes in Relapsing MS Treated With Ozanimod (RPC-1063)

    A study to determine if oral ozanimod can affect cognitive processing speed in people with relapsing MS. All subjects will receive orally administered ozanimod HCl 1 mg.  Please note: In response to the recent developments of the COVID-19 pandemic, sites are implementing me...
