After screening, patients meeting all of the inclusion / non-inclusion criteria and vaccinated against meningococcal infections were divided into two subgroups according to the eculizumab treatment status (Soliris® naïve patients / patients who had received Soliris® at a maintenance dose prior to the trial inclusion). Each subgroup included an even number of patients to maintain recruitment balance. Then, patients of each subgroup were distributed into one of two treatment groups by the method of stratified block randomization at a 1:1 ratio into groups A and B, respectively. In the first group (Group A), patients received infusions of Elizaria (eculizumab, GENERIUM JSC), in the second one (Group B) - infusions of Soliris®.~The duration of participation of each patient in the study, including the screening period, was about 30 weeks.
It is a multicenter, open-label, randomized, parallel-group study of the efficacy and safety of Elizaria® (eculizumab, GENERIUM JSC, Russia) versus Soliris® (Alexion Pharma GmbH, Switzerland) in patients with paroxysmal nocturnal hemoglobinuria.
