Divozilimab reduces the risk of exacerbations in patients with neuromyelitis optica spectrum disorders
https://doi.org/10.14412/2074-2711-2025-4-16-25
Abstract
Objective: the aim of the AQUARELLE trial was to evaluate the efficacy of divozilimab compared with a historical control (placebo) and to characterise its safety in patients with neuromyelitis optica spectrum disorder (NMOSD).
Material and methods. The AQUARELLE clinical trial population included patients aged 18 years and older with a diagnosis of NMOSD established in accordance with the international consensus diagnostic criteria for NMOSD (2015). The primary efficacy endpoint was the mean annual rate of confirmed exacerbations (MAR) over 6 months of treatment with divozilimab compared with a historical control, which was the placebo from the N-MOmentum study.
Results. A total of 105 patients received treatment with the investigational drug divozilimab. At the time of analysis, the proportion of patients without confirmed exacerbations was 94.3% (99/105); the ARR was 0.124 (95% CI 0.056–0.276). The ARR ratio for divozilimab /historical placebo was 0.172 (90% CI 0,083–0,359), indicating the superiority of divozilimab compared to historical placebo over 6 months of therapy. During divozilimab therapy, a therapy-related decrease in lymphocyte count was reported in 16 (15.2%) patients, and infusion reactions were reported in 6 (5.7%) patients. The overall incidence of therapy-related infectious events was 6 cases (5.7%).
Conclusion. Within patients with NMOSD, the use of divozilimab reduces the risk of exacerbations. The good tolerability of the drug allows divozilimab to be recommended as a new therapeutic option for patients with NMOSD.
