Active clinical trials for "Neuromyelitis Optica"

The goal of this clinical trial is to evaluate the safety and efficacy of nabiximols, a cannabinoid spray, for the treatment of moderate to severe spasticity in adult patients with AQP4-IgG positive and antibody-negative NMOSD. The main question it aims to answer is whether treatment with nabiximols improves patient-reported spasticity ratings compared to treatment with a placebo. This trial will also answer whether nabiximols impact pain, spasm frequency, mood, walking ability, and sleep. Participants will be mailed the treatments and placebo treatments, and will be asked to complete study visits and questionnaires remotely. There is also an optional sub-study that involves in-person visits with ultrasound imaging and in-person neurologic exams.

This study is being done to develop a database of pediatric patients in order to study the cause, early detection and best treatment for neuromyelitis optica spectrum disorder (NMOSD) in pediatric patients.

The 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.

This is a Prospective, observational research study for patients with NMOSD under the care of a licensed neurologist. Approximately 800 patients and 35 clinical sites in North America will be recruited to participate with no defined upper limit for either target.

In 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.

This study will examine the effectiveness of a neuromyelitis optics spectrum disorder (NMOSD) specific Acceptance and Commitment Therapy (ACT) intervention at reducing anxiety and depression in individuals with NMOSD and their caregivers/loved ones and improving overall health outcomes in individuals with NMOSD.

The objectives of this time-to-event study were to assess the efficacy and safety of eculizumab as compared with placebo in participants with neuromyelitis optica spectrum disorder (NMOSD) who were anti-aquaporin-4 (AQP4) antibody-positive.

Neuromyelitis Optica (NMO) is a demyelinating and degenerative disorder of the CNS affecting vision and spinal cord function. This disease is rare compared to Multiple Sclerosis (MS), but it is devastating and often leads to accumulating disability with a 5 year-mortality of approximately 30%. Survivors are typically left with severe morbidity secondary to blindness, quadriparesis and respiratory failure. No agent has been found to be highly effective in halting disease activity. Based on recent outcomes of stem cell transplant trials and reports in autoimmune diseases including MS, and based on the mechanisms of NMO, we anticipate that stem cell transplantation may provide lasting disease stability for NMO patients. The hypothesis of the present trial is that autologous hematopoetic stem cell transplantation in patients with NMO will provide lasting benefit in relapse prevention. Specifically, we anticipate a 50% reduction in the proportion of patients experiencing relapse over a three year period. We will be following patients for a total of five years after transplantation.

This multi-center randomized controlled trial evaluates if the addition of intravenous immunoglobulin to standard treatment of corticosteroids improves outcome in children and adults with first episode of Transverse Myelitis of Neuro-myelitis optica. Half of participants will receive corticosteroids alone, whilst the other half will receive corticosteroids plus intravenous immunoglobulin.

This study is aimed to observe the effectiveness and safety of inebilizumab in the acute phase of neuromyelitis optica spectrum disorders.
