Filter by:This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD19 CAR-T therapy for patients with relapsed or refractory Neuromyelitis Optica, and to evaluate the pharmacokinetics of CD19 CAR-T in patients.
Neuromyelitis Optica Spectrum Disorders (NMOSD) is associated with a pathological humoral immune response against the aquaporin-4(AQP-4) water channel. Baricitinib is an oral Janus kinase (JAK)1/JAK2 inhibitor that blocks the upregulated JAK-STAT pathway in patients with neuroimmune disorders, which is important in bone marrow regulation of B cell proliferation and differentiation. Baricitinib may benefit some patients with NMOSD due to the important role of B cells in the pathogenesis of NMOSD. Clincial trials may be needed to observe its efficacy and safety.
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).
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.
Restless legs syndrome (RLS) is a neurological movement disorder characterized by uncomfortable and uncontrollable sensations, usually in the legs, that increase at rest, and an urge to move the legs or other affected extremities. The exact cause of RLS is unknown, but there are idiopathic and secondary forms of RLS associated with various medical conditions such as anemia, pregnancy, uremia, neuropathies, rheumatoid arthritis, parkinson's disease, spinocerebellar ataxia, and neurological disorders such as multiple sclerosis. Neuromyelitis optica (NMO) is a severe inflammatory disease of the central nervous system. NMO, once considered a variant of multiple sclerosis, is now recognized as a separate disease entity. In 2004, the water channel protein-specific antibody called aquaporin 4 (AQP4) was found to cause NMO, leading to the identification of NMO as a separate disease. When initially described, the disease was thought to show only necrotic and demyelinating lesions in the optic nerve and spinal cord. It was therefore thought that NMO would preferentially only attack the optic nerves and spinal cord, not the brain. However, over the years, evidence from various studies has proven that various parts of the brain are also affected during the course of the disease. In addition, some patients showing features of the disease were found to be seronegative for anti-AQP4 antibodies. These findings necessitated the need to introduce a new term "neuromyelitis optica spectrum disorders (NMOSD)" to describe all the features of the disease. Although the feeling of restlessness in the legs is frequently reported as a sensory symptom by people with NMOSD, there are limited publications to investigate the relationship between RLS and NMOSD. The primary aim of the study is to determine the frequency and severity of RLS in people with NMOSD. The second aim of the study is to compare the presence and severity of RLS, sleep quality, daytime sleepiness level, quality of life, fatigue and Magnetic Resonance Imaging (MRI) results in people with NMOSD. The third aim of the study is to compare the cognitive functions of people with RLS positive and negative NMOSD. People with NMOSD who came to Dokuz Eylul University Medical Faculty Hospital Neurology Department MS Polyclinic for their routine check-ups, who volunteered to participate, will be included in the study.
NMOSDCopilot is a digital tool developed for the self-assessment of Neuromyelitis Optica Spectrum Disorder symptoms that impact patients' functioning and quality of life. It has been co-designed with the help of patient advocacy groups, NMOSD patients and medical experts. It includes a smartphone-based application for patients, connected to a web portal developed for healthcare professionals (HCSPs). The patient application is composed of vision, walking, cognition, and dexterity e-active tests inspired by clinical standards, as well as e-questionnaires. The HCP web portal is a desktop-based software that allows HCPs to access the results generated via the patient application and facilitates remote monitoring of patients' symptoms. The objectives of this study are to validate the accuracy, reliability and reproducibility of the unsupervised at-home self-assessment of symptoms on the patient's smartphone versus the standard in-clinic testing, as well as to evaluate the safety of use of the tool, its usability, and satisfaction towards the patient application among NMOSD patients, and the HCP web dashboard among HCPs.
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.
A Phase 2, open-label, multicenter study to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and safety of inebilizumab in eligible pediatric participants 2 to < 18 years of age with recently active neuromyelitis optica spectrum disorder (NMOSD) who are seropositive for autoantibodies against aquaporin-4 (AQP4-immunoglobulin [Ig]G).
This is an open-label, single-arm, multicentre prospective pilot study to assess the efficacy and safety of ofatumumab in patients with AQP4-IgG seropositive neuromyelitis optica spectrum disorder (NMOSD) in China.
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
