The primary treatment period will end when the last enrolled patient reaches week 50 unless a predefined number of patients have an adjudicated on-trial relapse by that time. The entire treatment period will last up to \~{}4.5 years.Conclusions ALXN1210-NMO-307 is an ongoing study evaluating the efficacy and safety of ravulizumab in patients with AQP4+ NMOSD. It is designed to be consistent with PREVENT, and robust statistical methods will address the potential impact of an external comparator.}, issn = {0028-3878}, URL = {//www.ez-admanager.com/content/99/23_Supplement_2/S4}, eprint = {//www.ez-admanager.com/content/99/23_Supplement_2/S4.full.pdf}, journal = {Neurology} }
