EPYSQLI (SB12; Biosimilar to Reference Eculizumab) in Asian and Non-Asian Patients With Paroxysmal Nocturnal Hemoglobinuria: Subgroup Analysis of a Global Phase III Randomized Controlled Trial.

ABSTRACT:

Introduction

SB12 demonstrated equivalence to reference eculizumab (ECU) in complement inhibitor-naïve patients with paroxysmal nocturnal hemoglobinuria (PNH) in the previous randomized, double-blind, multi-national, crossover, Phase III study.

Methods

The scope of this post-hoc study was subgroup analysis by race to compare the efficacy and safety of SB12 and ECU in PNH patients in the Asian and Non-Asian subgroups of the Phase III study.

Results

Results including lactate dehydrogenase (LDH), number of units of packed red blood cells and safety as primary and secondary endpoints demonstrated comparable efficacy and safety of SB12 and ECU in Asian and Non-Asian PNH patients, in line with the study results in the overall population. In addition, transfusion avoidance (
