Phase 3 Trial Data on Satralizumab Monotherapy in Neuromyelitis Optica Spectrum Disorder Published
Satralizumab as a monotherapy for the treatment of neuromyelitis optica spectrum disorder (NMOSD) reduced the rate of relapse compared with placebo, according to the results of a phase 3 trial. Full data from the trial were published in Lancet Neurology.
NMOSD is a rare disease characterized by optic neuritis or myelitis.
In this phase 3, double-blind, placebo-controlled, parallel-group trial, adult patients with aquaporin-4 antibody seropositive or seronegative NMOSD who had experienced ≥ 1 documented NMOSD attack or relapse in the previous 12 months and had a score of ≤ 6·5 on the Expanded Disability Status Scale, were included.
Of the 168 participants screened, 95 were randomly assigned to receive treatment with satralizumab (n = 63) or placebo (n = 32)
During the study period, 19 patients receiving satralizumab relapsed compared to 16 receiving placebo (hazard ratio 0·45, 95% CI 0·23–0·89; P = 0,018)
Serious adverse events and adverse events leading to withdrawal was similar between groups.
