Therapeutic equivalence of epoetin zeta and alfa, administered subcutaneously, for maintenance treatment of renal anemia

Introduction The primary objective of the trial was to prove the therapeutic equivalence of epoetin zeta to epoetin alfa when administered subcutaneously for maintaining target hemoglobin (Hb) in patients with renal anemia on chronic hemodialysis. Additional information was provided on the safety and tolerability of epoetin zeta with particular focus on the formation of anti-erythropoietin antibodies.
