Biosimilar Erythropoietin in Anaemia Treatment (Maintenance Phase Study)

This study is aimed to comprehensively establish the bio-similarity/bioequivalence in EPIAO® and EPREX® in terms of 52-week comparisons in efficacy, safety and immunogenicity. The targeted population is anaemia patients with end-stage chronic renal disease who previously received epoetin treatment and on haemodialysis.

This is a prospective, randomized, double blind, parallel group two arm study to establish the therapeutic equivalence, safety and tolerability of EPIAO® as compared to EPREX® in the treatment of CKD related anaemia in subjects who are on haemodialysis. A total of 264 subjects will be randomized into two groups in a 1:1 ratio. Treatment arm A will receive EPIAO® 1-3 times a week, intravenously for period of 52 weeks and treatment arm B will receive EPREX, 1-3 times a week, intravenously for period of 52 weeks.
