Therapies specifically approved by the U.S. Food and Drug Administration (FDA) for neuromyelitis optica spectrum disorder (NMOSD) are superior to rituximab and other off-label medications at preventing relapses and serious side effects, according to a real-world study in the U.S. The study also showed that among FDA-approved therapies, the…

Note: This column describes the author’s own experiences with Ultomiris (ravulizumab-cwvz). Not everyone will have the same response to treatment. Consult your doctor before starting or stopping a therapy. When Alexion Pharmaceuticals first approached me about being featured for Rare Disease Day on Feb. 28, I initially declined the offer.

Add-on hyperbaric oxygen therapy (HBOT), which involves breathing pure oxygen at high pressure, may help reduce inflammation in people with neuromyelitis optica spectrum disorder (NMOSD), especially those with more overactive immune systems, a small study suggests. “HBOT may help rebalance the immune system in NMOSD,” researchers wrote, noting that…

Soliris (eculizumab) is linked to a reduced relapse rate and stabilization of disability progression in people with neuromyelitis optica spectrum disorder (NMOSD) who test positive for anti-AQP4 antibodies, according to a real-world study in Turkey. “These results support [Soliris] as a valuable therapy for [AQP4-related] NMOSD, while stressing the…

A U.S.-based registry of adults with neuromyelitis optica spectrum disorder (NMOSD) shows that most patients are receiving biologic therapies, either approved or not approved for NMOSD, in real-world care, according to a study of its first 350 participants. The registry, called SPHERES, has enrolled about half of…

People with neuromyelitis optica spectrum disorder (NMOSD) who are negative for typical disease-driving antibodies show several differences in clinical features compared with antibody-positive NMOSD patients, but responses to conventional treatments seem largely comparable, according to a new study. “Our findings support the utility of conventional [immune-suppressing treatments] in this…

Enspryng (satralizumab) is superior to conventional immunosuppressive therapies in reducing the risk of relapses in people with neuromyelitis optica spectrum disorder (NMOSD) for up to three years, and with a comparable safety profile, according to a real-world study. Similar results were obtained when analyzing data only from NMOSD…

Newer, more potent therapies offer greater benefit than standard immunosuppressants in reducing relapse rates for people who develop neuromyelitis optica spectrum disorder (NMOSD) after the age of 50, according to a large, single-center study in China. While people with late-onset NMOSD experienced more severe symptoms at onset and during…

Double-filtration plasmapheresis (DFPP), an advanced blood-cleaning procedure, is equally effective as high-dose corticosteroids for treating acute attacks associated with neuromyelitis optica spectrum disorder (NMOSD), but comes with fewer side effects, according to a new study from China. DFPP selectively removes disease-driving self-reactive antibodies from the bloodstream while retaining…

People with neuromyelitis optica spectrum disorder (NMOSD) have abnormally high levels of S100A9, a protein that drives the inflammatory activity of certain immune cells, a study discovered. According to the researchers, higher S100A9 levels in the blood were significantly associated with more severe disability among patients. These findings thus…
