Objective: To assess the therapeutic equivalence of epoetin zeta and epoetin alpha for correction of haemoglobin (Hb) concentration in patients with anaemia and chronic kidney disease (CKD) stage 5 maintained on haemodialysis.
Study Design: In total, 609 patients with CKD and anaemia (Hb < 9 g/dL) were randomly assigned to receive either epoetin zeta or epoetin alpha intravenously, one to three times per week for 24 weeks. Dosing was titrated individually to achieve a stable, target Hb concentration of 11-12 g/dL.
