Filter by:The purpose of this proof of concept study is to assess the acceptability and safety of MR-C-014 in persons with Neuromyelitis optica spectrum disorder (NMOSD) who have a gait deficit.
The primary objective of this study is to describe the frequency and characteristics of pregnancy outcomes and maternal complications among participants exposed to Ultomiris and to describe the frequency and characteristics of selected fetal/neonatal/infant outcomes in utero, at birth, and through 1 year of age after exposure in utero or via breastmilk.
The RECLAIM study aims to gather a centralized and harmonized dataset, enabling the secondary use of data for building AI-based models that will support diagnosis and prognosis of individual Multiple Sclerosis patient's disease course and treatment response in a real-world setting. Additionally, the data will be used to generate further insights on Multiple Sclerosis progression as well as to develop the tools to monitor this progression.
To assess the efficacy and safety of Inebilizumab in Chinese adult patients with neuromyelitis optica spectrum disorders.
This study aims to retrospective investigate the safety and effectiveness of Efgartigimod in the acute phase of neuromyelitis optica spectrum disorders (NMOSD) patients.
To compare the safety and efficacy of Inebilizumab and Rituximab in neuromyelitis optica spectrum disorders (NMOSD) patients.
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 aimed to observe the effectiveness and safety of inebilizumab in the acute phase of neuromyelitis optica spectrum disorders.
This is a multicenter, randomized, double-blind, placebo-controlled Phase Ⅱ study to evaluate the efficacy and safety of Mitoxantrone Hydrochloride Liposome Injection with different doses in participants with neuromyelitis optica spectrum disorder (NMOSD). Participants will be randomly enrolled into three groups: Mitoxantrone Hydrochloride Liposome Injection 8 mg/m^2 group, Mitoxantrone Hydrochloride Liposome Injection 12 mg/m^2 group, and Placebo group. The primary outcome measure is time to first protocol-defined relapse.
Neuromyelitis optica spectrum disorders (NMOSD) are severe inflammatory autoimmune conditions of the central nervous system (CNS) . The discovery of NMOSD-specific aquaporin 4 (AQP4) antibody has established that NMOSD is indeed a distinct entity . Approximately 80% of patients with NMOSD test positive for aquaporin-4 (AQP4) immunoglobulin G (IgG) antibodies .AQP4-IgG associated NMOSD appears to target astrocytes, not myelin, leading to elevated markers of astrocyte injury during attacks . Untill now there is limited research about understanding the biomarkers of astrocyte injury and the following reactive gliosis. Family with sequence similarity 19-memberA5 (FAM19A5) protein is postulated to regulate nervous and immune cells of the brain as a brain-specific chemokine, but its precise functional role is not well understood . A recent study suggested that FAM19A5 is secreted by reactive astrocytes following CNS damage and triggers reactive gliosis . In another recent study, serum FAM19A5 was higher in patients with NMOSD-AQP4 than in other CNS demyelinating diseases and healthy controls . So, we need to study the level of this novel biomarker among our Egyptian NMOSD patients and whether it shall be a new biomarker for NMOSD . Moreover just few studies conducted on cognitive dysfunctions in NMOSD patients and they demonstrate a significant decrease of cognitive abilities and the prevalence of CI in different samples varies between 30 and 70% .So further studies are needed to investigate the cognitive performance in NMOSD patients
