A Study to Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Satralizumab in Participants With Myelin Oligodendrocyte Glycoprotein Antibody-associated Disease

The main objective of this study is to evaluate the efficacy of satralizumab compared with placebo based on time from randomization to the first occurrence of an adjudicated MOGAD relapse in the double-blind (DB) treatment period. Participants who experience an adjudicated relapse or complete the DB period can enter open-label extension (OLE) period. After the primary clinical cutoff date (CCOD), additional adolescent participants may be enrolled directly into the OLE period.

Integrating Metabolism, Connectivity, and Mesoscale Imaging at Ultra-high Field to Decipher Mechanisms of Resilience and Neurodegeneration in Neurological Diseases and Healthy Aging

The MESO7 study is a prospective observational research project designed to investigate the mechanisms of resilience and neurodegeneration in neurological diseases and healthy aging. It leverages advanced multiparametric brain and spinal cord imaging at high (3T) and ultra-high magnetic fields (7T) to assess structural, functional, metabolic, and mesoscale changes in the central nervous system (CNS). Particular emphasis is placed on sodium (23Na-MRI) and phosphorus (31P-MRI) imaging, along with layer-dependent brain connectivity analysis. The primary objective is to evaluate the impact of neuronal energy failure, measured via sodium concentration, on functional and structural reorganization in both healthy individuals and patients with various neurological conditions. Directed brain network models will be constructed from MRI data to quantify the connectivity strength (in- and out-degree) of cortical nodes. These connectivity metrics will be correlated with sodium concentrations to assess energy failure and its role in network reorganization. Longitudinal follow-up over two years is planned for subgroups with clinically progressive diseases. Secondary objectives include decoding metabolic, microstructural, and functional signatures of successful aging at the laminar level; characterizing disease-specific patterns of cortical and spinal microstructure associated with physical and cognitive dysfunction; describing longitudinal mesoscale and metabolic changes; and generating representative normative imaging datasets for the neuroscience community. The study plans to enroll a total of 540 patients across 9 neurological conditions:Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorders (NMOSD), MOG Antibody Disease (MOGAD), Alzheimer's disease, Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), temporal and non-temporal epilepsy, and mild traumatic brain injury (mTBI),in addition to 160 age- and sex-matched healthy controls, totaling 700 participants. Imaging and clinical assessments will be performed at the CEMEREM center at Timone University Hospital, AP-HM, Marseille, France. Each participant will undergo multiparametric brain and spinal cord MRI, including DTI, BOLD, MP2RAGE, SWI, quantitative sodium and phosphorus imaging, and functional assessments including neuropsychological testing, visual and motor function tests. Disease-specific assessments such as OCT, evoked potentials, and disability scores (e.g., EDSS for MS) will also be included when appropriate. The study is expected to improve understanding of CNS adaptation mechanisms and support the development of more accurate diagnostic and prognostic tools for neurodegenerative diseases

Swiss Pediatric Inflammatory Brain Disease Registry (Swiss-Ped-IBrainD)

The Swiss-Ped-IBrainD is a national patient registry that collects information on diagnosis, symptoms, treatment, and follow-up of pediatric patients with an inflammatory brain disease in Switzerland. It was first implemented in 2020 in the pediatric clinic of the university hospital in Bern. Further centers all over Switzerland opened for recruitment after that: Aarau, Basel, Bellinzona, Chur, Geneva, Lausanne, Lucerne, St. Gallen, Winterthur and Zurich. The center in Fribourg is expected open for recruitment in 2025. The registry provides data for national and international monitoring and research. It supports research on inflammatory brain diseases in Switzerland and the exchange of knowledge between clinicians, researchers, and therapists. The registry aims to improve the treatment of children with inflammatory brain diseases and optimizing their health care and quality of life.

Safety and Efficacy of CT103A Cells for Relapsed/Refractory Antibody-associated Inflammatory Diseases of the Nervous System

Antibody-mediated inflammatory diseases of the nervous system (also known as autoimmune diseases of the nervous system) are autoimmune diseases in which autoimmune cells and immune molecules attack the nervous system as the main pathogenic mechanism. In the immune response, pathogenic antibodies acting on autoantigens of the nervous system are collectively referred to as autoantibodies of the nervous system, and antibody-mediated inflammatory diseases of the nervous system can occur in the central nervous system, peripheral nervous system, and neuromuscular junctions, and muscles. In this study, we will recruit eight kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), idiopathic inflammatory myopathyand (IIM), multiple sclerosis (MS), autoimmune encephalitis (AE), Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD) and POEMS Syndrome. B-cell maturation antigen (BCMA) is expressed on the surface of plasma cells, thus making it an ideal target for targeted therapies. Chimeric antigen receptor (CAR) T cells against BCMA offers another potential therapeutic option to eliminate plasma cells in patients with neurological autoimmune diseases driven by abnormal antibody who still suffer recurrent attacks from conventional treatments. In the current study, the safety and efficacy of a novel CAR-T cell therapy using CT103A cells, are evaluated in patients with relapsed/refractory antibody-mediated idiopathic inflammatory diseases.
