NCT06620809
This is a single-center, randomized, open-label, placebo-controlled, dose-escalation trial. The objective of this research is to evaluate the safety, tolerability, and efficacy of intrathecal administration of human-induced neural stem cell-derived extracellular vesicles (NouvSoma001) for the treatment of neuromyelitis optica spectrum disorders.

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
NCT06413654
To evaluate the efficacy and safety of B001 injection in aquaporin-4 antibody positive patients with neuromyelitis optica spectrum disorder.
NCT06485232
This is an open label, single-site, dose-escalation study in up to 25 participants with refractory autoimmune diseases of nervous system. This study aims to evaluate the safety and efficacy of the treatment with universal BCMA and CD19 CART.
NCT05730699
The goal of this clinical trial is to study the efficacy and safety of BCD-132 (divozilimab) in subjects with neuromyelitis optica spectrum disorders (NMOSD).
NCT04670770
This is an open-label study, to evaluate the efficacy and safety of SHR1459 in participants with NMOSDs.
NCT02850705
Devic's neuromyelitis optica (NMO) is rare. Epidemiological and demographic data are poor, based mainly on monocentric cohorts. Moreover, NMO might be difficult to distinguish from multiple sclerosis and begin with atypical or incomplete clinical presentations. Therefore, NMO is still underdiagnosed. The constitution of a nationwide and prospective cohort, including not only NMO but also clinical syndromes suggestive of a first episode (DNMO-spectrum disorders (SDs)), should allow to gather a critical mass of cases and answer questions that could not have been addressed at the level of a single centre. Objectives: The main objective is to describe the clinical, radiological and biological features of NMO spectrum disorder (NMO, isolated longitudinally extensive transverse myelitis (LETM), relapsing or not; isolated atypical optic neuritis (ON)) and their evolution. The second aim is to create a biobank dedicated to NMO (serum, whole blood for RNA and DNA extraction, cerebrospinal fluid), to promote translational research in the field. Methods: NOMADMUS is a prospective, multicentre, observational study of patients NMOSD and related disorder in France. Prevalent cases are included retrospectively and then followed prospectively. Incident cases are included from disease onset and followed prospectively. A minimal set of data has been defined and synthesized on specific paper forms derived from the European database for multiple sclerosis (EDMUS) forms. Patients are systematically tested regarding their AQP4-IgG and MOG-IgG status. All the data are centralised in a EDMUS-derived database in Lyon, the EDEN software. All cases are validated and classified by an expert committee.
NCT02889965
OFSEP is an observational cohort of Multiple Sclerosis (MS) and related disorders set up in France. It aims to provide a major epidemiological tool on MS for the scientific community in France and abroad. This tool must help to answer a large number of questions concerning the causes and mechanisms of MS, the prognostic factors of disease progression, the effectiveness and safety of therapeutic drugs, the impact of the disease on patients and society, etc. In December 2015, it has already included more than 54.000 patients. To achieve this goal, OFSEP's objectives are * To maintain and develop the French cohort of patients suffering from MS or related diseases and syndromes. This means collecting standardized socio-demographic and clinical data as part of the routine medical follow-up of patients already in the cohort and recruitment of new patients. * To supplement the existing clinical data with standardized and quality biological samples and MRI scans. * To improve the previous data with medical/administrative data from the health insurance fund databases in particular, in order to get more information on comorbidity, treatment protocols and the medico-economic aspects of this disease. * To use OFSEP infrastructures to facilitate the implementation of specific studies requiring the collection of additional data or specific patient monitoring processes. * To ensure the availability of these data and samples to researchers, health care authorities and industrial players to enable analysis and thus provide answers to research questions or public health issues. This availability is only possible after scientific and regulatory evaluation of the request. * To provide regular descriptions of the patient population in the cohort to offer statistics, targets and up-to-date information on this disease and thus enable a better approach to the personal, professional and social impacts of the illness, the effects of basic treatments and the requirements related to the follow-up of this disease in France. * To conduct specific studies on the entire population of patients in the cohort (parent cohort) or on patient sub-groups with specific characteristics (nested cohorts). Four nested cohorts have been defined: patients with radiologically isolated syndromes, patients with clinically isolated syndromes, patients with primary progressive courses of the disease and patients with neuromyelitis optica (Devic's syndrome) spectrum disorders.
NCT02021825
The treatment protocol consisted of 12 mg/m2 MITO intravenous infusions every 3 months for 2 years. Dosage was adjusted according to side effects. Neurological assessment including the determination of the Expanded Disability Status Scale (EDSS) score and ophthalmologic evaluations were performed every 3 months and during relapses. Flow cytometric analysis, brain and spinal cord MRI was performed at baseline, 6, 12, 18, and 24 months.
