NMOSD

Neuromyelitis Optica Spectrum Disorder (NMOSD) is a rare autoimmune condition that mainly affects the eyes and spinal cord, causing serious symptoms such as vision loss, paralysis, and severe pain. This trial compares the effectiveness and safety of five medications commonly used to prevent NMOSD relapses: rituximab, ravulizumab, inebilizumab, satralizumab, and eculizumab. In this study, 160 adults with NMOSD who test positive for a specific antibody (AQP4-IgG) will participate. They will be randomly assigned to receive either rituximab or one of the four other FDA-approved medications. The main goal is to find out which treatment best prevents relapses and has fewer serious side effects. The trial will also measure disability, patient satisfaction, quality of life, and biomarkers that help track disease activity. Participants will have regular assessments, including medical exams, surveys, and tests for vision, walking ability, and brain function. They will report any side effects or health issues experienced during the study. The trial will last from one to four years for each participant. This research aims to help patients and doctors make better-informed treatment decisions by providing clear evidence about the best available therapies for NMOSD.

The primary objective of this study is to confirm the efficacy, safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of ravulizumab in the treatment of Chinese adults with anti-aquaporin-4 (AQP4) antibody (Ab) + neuromyelitis optica spectrum disorder (NMOSD).

Long-term, multicenter, multinational, observational, registry of patients with AQP4+ NMOSD that is designed to collect data on clinical outcomes and safety in patients prescribed Alexion C5 inhibitor therapies (C5IT). The registry will also collect data on patient reported outcomes (PROs), quality of life (QoL), and targeted AQP4+ NMOSD therapies used to provide evidence on the real-world impact of ALXN-C5IT on patients with AQP4+ NMOSD.

This study will primarily evaluate the pharmacokinetics of satralizumab in pediatric patients aged 2-11 years with anti-aquaporin-4 (AQP4) antibody seropositive neuromyelitis optica spectrum disorder (NMOSD). Efficacy, safety, tolerability, and pharmacodynamics will be evaluated in a descriptive manner, given the small number of patients who will be enrolled in this study.

This is an open clinical pharmacological translational Research Study, aiming to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of RD06-05 in patients with active SLE, SSc, AAV, IIM, NMOSD, MS, MG

This study aims to characterize sex hormone alterations and their potential clinical significance in NMOSD patients from Southern China through comprehensive hormonal profiling.

This study aims to evaluate the efficacy and safety of different monoclonal antibody in the acute phase of neuromyelitis optica spectrum disorder (MAAP-NMO). It will also examine immune-related biomarkers and their relationship with treatment response to provide evidence for optimizing acute-phase therapeutic strategies.

This study aims to explore the imaging and electrophysiological characteristics of idiopathic inflammatory demyelinating diseases (IIDDs), and their correlation with clinical manifestations. It also evaluates the effectiveness of transcranial electrical stimulation in alleviating clinical symptoms of IIDDs patients, and analyzes the key factors affecting the treatment efficacy. By uncovering the overall and individual characteristics of IIDDs, this study seeks to enhance therapeutic outcomes through personalized neuromodulation programs. The findings will provide a basis for applying non-invasive brain stimulation (NIBS) in IIDDs treatment and offer new ideas for future personalized medicine approaches.

This is a nationwide observational study looking at how ravulizumab, a complement C5 inhibitor, affects blood biomarkers o sNfL and sGFAP in people with AQP4-antibody positive NMOSD. The study does not change your treatment-only regular blood samples are collected to monitor these markers

PRISMA, is a pregnancy registry study, focused on comprehensively collecting information about pregnancy in women with chronic neurological conditions from across the United States and internationally. Depending on their specific condition (MS, CIS, NMOSD, or other) and their specific treatment, participants will be asked to contribute to different aspects of the study. (1) The biosamples will be blood, breast milk, infant stool, maternal stool and vaginal swab samples, collected at specific time points. (2) The online surveys will be collected at specific time points. All study activities will be discussed with participants upon enrollment. By collecting this information, the investigators hope to gain deeper insights into the relationship between pregnancy, the neurological condition, and maternal and infant health. For example, one of the sub-studies focuses on breast milk collection for women planning postpartum treatment with Ocrevus, Rituxan, Briumvi or Kesimpta. This study is fully remote and all sample collection is optional, so participants can choose which types of samples they wish to provide. For blood draws, participants can schedule a home visit through ExamOne, making participation even more convenient. The investigators aim to enroll women with chronic neurological conditions who are planning pregnancy, currently pregnant, or within one year postpartum.
