Viela Bio reported updated safety, efficacy and long-term use results of UPLIZNA®(inebilizumab-cdon), including interim data from the open-label extension period (OLP) of the pivotal N-MOmentum trial in patients with neuromyelitis optica spectrum disorder (NMOSD). Data from four scientific abstracts were selected for presentations during the American Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) 2021 Forum, which is being held virtually from February 25-27, 2021. Among the highlights in patients treated with UPLIZNA® — the first and only FDA-approved B-cell depleter for the treatment of adult patients with anti-aquaporin-4 (AQP4) antibody positive NMOSD — a reduction of attacks was sustained for the duration of the four-year observation period (with two patients on therapy for more than four years). Consistent with previous clinical results, no new safety signals were observed, regardless of the patient’s prior exposure to off-label therapy.
