Multiple SclerosisNeuromyelitis Optica Spectrum Disorder1 moreThis is an uncontrolled, prospective, observational cohort study to assess the function of meningeal lymphatic drainage and dynamics of immune cells in patients with relapsing multiple sclerosis (RMS) or Neuromyelitis optica spectrum disorder (NMOSD) after receiving ofatumumab treatment over an observational period of 12 months.
Gray Matter Demyelination in Primary Progressive MS at 7T
Primary Progressive Multiple SclerosisProgressive-onset multiple sclerosis (PPMS) occurs in about 15% of all people living with MS. PPMS remains understudied, and most disease-modifying treatments are ineffective for PPMS. To date, it is unknown why some people progress immediately from MS onset. The present study will assess the role of gray matter in PPMS by characterizing it with ultra-high field magnetic resonance imaging (MRI). While both white and gray matter are affected in relapsing MS, in PPMS tissue damage is primarily in the cortex. Cortical gray matter consists largely of neuronal cell bodies, which send electrical signals to create a functional response, such as arm or leg movement. While white matter damage slows the signal response, cortical damage inhibits the initial creation of electrical signals. There is a great need to research and develop scientific biomarkers to identify and monitor progression and repair in PPMS. In this project, 7 Tesla MRI is used to investigate the cortical gray matter in people with PPMS. 7 Tesla MRI is the safest and most detailed way to study the brain. Because the cortex is only a few millimeters thick, it has been traditionally difficult to investigate. At 7 Tesla, different layers and lesions within the cortex can be seen. In addition, this project will use myelin-sensitive MRI to determine the biological underpinnings of both cortical lesions and the 'normal appearing' cortical damage in PPMS. This will answer relevant questions about the brain's capacity for repair, the extent of demyelination and the occurrence of inherent cortical remyelination and provides an avenue for the development of novel clinical MR biomarkers tailored to PPMS.

Assessing Changes in Multi-parametric MRI in Patients With Acute Demyelinating Lesions Taking Clemastine...
Demyelinating DiseasesDemyelination; Corpus Callosum4 moreThe clinical trial is intended to assess for clinical evidence of Clemastine Fumarate as a myelin repair therapy in patients with acute inflammatory injury-causing demyelination as measured by multi-parametric MRI assessments. No reparative therapies exist for the treatment of acute demyelinating lesions. 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 acute 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 lesions found in patients with a confirmed diagnosis of acute inflammatory injury-causing demyelination. 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 acute lesions found in patients with a confirmed diagnosis of acute inflammatory injury-causing demyelination and compare it to the other assessments.
Acute Optic Neuritis Network: an International Study That Invesitages Subjects With a First-ever...
Demyelinating DiseasesMultiple Sclerosis3 moreThe goal of this observational study is to longitudinally investigating subjects with inaugural acute optic neuritis (ON). The main questions it aims to answer are: Does the time to corticosteroid treatment affect the visual outcome at 6 months in subjects with acute multiple sclerosis (MS)-, aquaporin 4-IgG positive (AQP4-IgG+) and myelin-oligodendrocyte-glycoprotein-IgG positive (MOG-IgG+) ON? How differ clinical, structural, and laboratory biomarkers in subjects with acute ON, including clinical isolated syndrome (CIS), MS-ON, AQP4-IgG+ON, MOG-IgG+ON and seronegative non-MS-ON? Participants will undergo clinical examination, including clinical history, neurovisual and neurological tests serum and cerebrospinal fluid examination optical coherence tomography (OCT) magnetic resonance imaging (MRI) assessment of depression, pain, quality of life through validated questionnaires Researchers will compare subjects with MS-ON, AQP4-IgG+ON, MOG-IgG+ON and other ON (CIS, seronegative non-MS-ON) to detect diagnostic and predictive markers for the disease course.
Validation of Cutaneous Nerve Demyelination in Diagnosis and Treatment of CIDP
CIDPThe goal of this observational study is to learn about chronic inflammatory demyelinating polyneuropathy. The main question the investigators would like to answer is 1) can skin biopsy identify demyelination better than nerve conduction studies (electrical tests of the nerves)? and 2) how do nerves improve after treatment in CIDP? Participants will be asked to undergo skin biopsy of the finger at baseline and at 3 months and 6 months after treatment with IVIG (which is the FDA approved treatment for CIDP).
Longitudinal Cortical Demyelination in Multiple Sclerosis and Related Disorders
Multiple SclerosisNeuromyelitis Optica2 moreIn this protocol, a combination of MRI, blood, and cerebrospinal fluid (CSF) analysis will be used to understand the natural history, underlying immunologic mechanisms, and clinical implications of central nervous system (CNS) lesions, in particular lesions in the cerebral cortex, in multiple sclerosis (MS) and other inflammatory and autoimmune disorders affecting the CNS. Patients with these disorders, as well as healthy controls, will undergo baseline clinical evaluation and testing, bloodwork, and MRI, with follow up clinical evaluation, bloodwork, and MRI at years 1, 3, and 6. Additional MRIs may be performed in patients with possible new lesion formation or to compare MRI techniques. Lumbar puncture will be performed on participants who are not currently being treated with disease modifying therapies and who are willing to undergo the procedure.
Modeling and Treating the Pathophysiology of Demyelination in Multiple Sclerosis
Multiple SclerosisThe investigators principal hypothesis is that INO and optic neuritis are objective, quantitative, and reproducible models for corroborating the hypothesis that changes in core body temperature are associated with the reversible and stereotypic decay in axonal conduction and that ACTHAR can serve to prevent such changes. The application of ocular motor and optic nerve measures appears to constitute a useful paradigm to detect and monitor responses to therapeutic strategies that stabilize nerve cell membranes in response to temperature induced decay in axonal conduction mechanisms, with implications on activities of daily life that are dependent upon vision (reading, driving, walking, work performance).
