FDA approves AstraZeneca's Ultomiris for treating adult NMOSD patients with AQP4 antibodies.

AstraZeneca's Ultomiris (ravulizumab-cwvz) has been approved by the FDA for treating adult patients with anti-aquaporin-4 (AQP4) antibody-positive neuromyelitis optica spectrum disorder (NMOSD). The approval was based on the CHAMPION-NMOSD Phase III trial, which showed a significant reduction in relapse risk compared to a placebo. Ultomiris is the first and only long-acting C5 complement inhibitor approved for this indication, and it is already approved for certain adults with NMOSD in Japan and the European Union.
