The risk of neuromyelitis optica spectrum disorder (NMOSD) attacks following vaccination is low, and such attacks have not been found to be associated with any particular type of vaccine, according to a review study. Also, post-vaccine attacks tended to happen more frequently in men, patients negative for antibodies against…

A small subset of people with neuromyelitis optica spectrum disorder (NMOSD) do not accumulate significant functional disability in the 15 years following symptom onset, according to a recent study. Called benign NMOSD, these patients were more likely to be Caucasian, less likely to have spinal cord involvement at disease…

SPHERES, a real-world registry for neuromyelitis optica spectrum disorder (NMOSD), is now collecting biological samples from consenting participants. Launched by CorEvitas and the Guthy-Jackson Charitable Foundation (GJCF) in 2021, the registry had been collecting long-term clinical data, but not biological samples. “The launch of this biospecimen…

High-efficacy treatments for neuromyelitis optica spectrum disorder (NMOSD) are associated with significant reductions in hospitalizations, relapses, and MRI lesions relative to traditional therapies, according to a recent study. The findings, which were published in the Journal of Neurology, were discussed in an oral presentation at the American…

Up to 4.6 years of treatment with Enspryng (satralizumab) continues to safely reduce relapse rates and prevent disability progression for people with neuromyelitis optica spectrum disorder (NMOSD) who are positive for antibodies against aquaporin-4 (AQP4). That’s according to pooled data from the Phase 3 SAkuraSky (NCT02028884) and…

For one in three people with neuromyelitis optica spectrum disorder (NMOSD), bad days — marked by high levels of debilitating symptoms — are more common than good days. Patients who are more comfortable talking with their doctors about their symptoms reported fewer bad days and greater treatment…

Ad Scientiam is developing new digital biomarkers of neuromyelitis optica spectrum disorder (NMOSD) that may allow continuous and remote monitoring of patients’ symptoms over time. The Paris-based software company announced the program launch along with a similar one for people with generalized myasthenia gravis, another rare autoimmune…

Uplizna (inebilizumab) does not increase the risk of COVID-19 infection or reduce the levels of antibodies produced from prior childhood vaccines among people with neuromyelitis optica spectrum disorder (NMOSD). That’s according to two posterior analyses of data from the Phase 2/3 N-MOmentum clinical trial (NCT02200770) after the…

The onset of neuromyelitis optica spectrum disorder (NMOSD) at an older age is linked with a greater likelihood of spinal cord involvement at the first disease attack, fewer relapses, and greater disability, according to a study in China. “Age of disease onset correlates with clinical characteristics and prognostic outcomes…

The activation of two types of immune cells — called natural killer (NK) and natural killer T-cells (NKT) — may contribute to the abnormal immune attacks that drive neuromyelitis optica spectrum disorder (NMOSD), a study suggested. The profile of these cells in NMOSD patients differed notably from that observed…
