简要总结
This study is a phase III, randomized, open label, two arm, multi-center trial comparing the safety and efficacy of Darbepoetin alfa and Erythropoietin alfa in the treatment of anemia in chronic kidney disease in 236 predialysis and dialysis patients from India. Patients will be randomized in 1:1 ratio between treatment arms and based on previous erythropoietin status (treated or naïve) dose for Darbepoetin alfa and Erythropoietin alfa are administered by subcutaneous injection. The primary outcome will be to assess mean change in hemoglobin between baseline and first evaluation period between the two treatment arms. The secondary outcomes will be to assess the hemoglobin variability, proportion of patients achieving hemoglobin increase ≥1 g/dl from baseline and target of 10-12 g/dl at the end of first evaluation period and time to achieve hemoglobin target range. Pharmacokinetic and immunogenicity will also be evaluated in these patients. The total treatment duration may vary depending on the hemoglobin response and dose titrations.
