In neuromyelitis optica spectrum disorder (NMOSD), enhanced plasma cell activity contributes to antiaquaporin-4 autoantibody (AQP4-ab) production.1 Longitudinal data indicate that 25% to 66% of patients with NMOSD who are treated with azathioprine, rituximab, and other immune-modifying therapies still experience relapses.2 Here we assess the safety and efficacy of bortezomib, a selective inhibitor of the 26S proteasome subunit, among patients with highly relapsing NMOSD.
