Title: A Multicenter, Randomised, Double-Blind Study Comparing De Novo Once Monthly and Once Every 2 Week Darbepoetin Alfa Dosing for the Correction of Anemia in Subjects With Chronic Kidney Disease Not Receiving Dialysis
Brief Summary: The purpose of this study is to determine whether once monthly (QM) dosing of darbepoetin alfa is non-inferior to that of once every 2 week (Q2W) dosing of darbepoetin alfa for the correction of anemia in patients with Chronic Kidney Disease who are not receiving dialysis.

  5. Patients who had hypersensitivity to erythropoietin agents
  6. Patients who had known hypersensitivity to mammalian cell-derived products or additives
  7. Patients with history of severe cardiovascular diseases
  8. Patients whose anemia is not caused by chronic renal failure or may affect anemia correction including the following conditions:
