Self-reactive antibodies linked to other autoimmune diseases are more common in people with neuromyelitis optica spectrum disorder (NMOSD) than in those with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), a related condition. In fact, the frequency of any other autoimmune disease was nearly six times higher in adults with NMOSD…

SAB Biotherapeutics has developed therapeutic antibodies — without the need for human donors — that can neutralize self-reactive antibodies associated with autoimmune diseases, such as neuromyelitis optica spectrum disorder (NMOSD). Working in collaboration with CSL Behring, a partnership established in 2020, SAB used its DiversitAb…

SAB Biotherapeutics’ DiversitAb platform has generated specialized antibodies against multiple regions of an abnormal self-reactive antibody, or autoantibody, associated with neuromyelitis optica spectrum disorder (NMOSD). The new antibody-based therapy was found to effectively bind to the NMOSD-causing autoantibody and neutralize it in both in vitro (in lab dishes) and in vivo (inside a…

Treatment with Uplizna (inebilizumab-cdon) can reduce levels of antibodies that drive neuromyelitis optica spectrum disorder (NMOSD), new clinical trial data show. The data also show that, among patients who aren’t on Uplizna, NMOSD attacks are often preceded by a sharp rise in levels of disease-driving antibodies and/or antibody-producing…

Using a live cell-based assay to test for the presence of aquaporin-4 antibodies (AQP4-IgG) can accurately identify people who have neuromyelitis optica spectrum disorder (NMOSD), new research suggests. Scientists said the cell-based assay was “a highly specific diagnostic biomarker of NMOSD and did not yield false positive results.” These findings…
