INTRODUCTION Neuromyelitis optica spectrum disorders (NMOSD) are rare but often devastating neuroinflammatory autoimmune diseases of the central nervous system. Acute treatment is critically important and it should be initiated early and aggressively, as relapses result in severe residual disability. Acute treatments are still based on clinical experience and observational studies. The most commonly used treatments are steroids and plasmapheresis. Several new treatments to improve management and recovery after relapses in NMOSD are currently under investigation. AREAS COVERED : This review discusses current and the most recent advances in active development of phase II/III clinical trials for acute treatment options and therapeutic strategies that can help management improvement of NMOSD during a relapse. These treatments include bevacizumab, ublituximab and HBM9161. EXPERT OPINION NMOSD relapses require prompt evaluation and timely treatment to restore function and mitigate disability. Timing is critical. Plasmapheresis showed better outcomes in terms of recovery when compared to high-dose intravenous methylprednisolone alone. Some groups suggest that plasmapheresis could be considered as an initial treatment approach in different clinical scenarios due to its higher effectiveness. Future research and/or real-world data will establish the advantages and disadvantages of these new treatments and define the appropriate patient profile.
