Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed study is designed to test a novel dosing paradigm that would facilitate the treatment of anemia in CKD patients not on dialysis. Anemic patients who have achieved and maintained target hemoglobin (Hb) on every 2 weeks (Q2W) dosing of darbepoetin alfa will have the dosing interval extended to once monthly (QM) dosing. Extending the dosing interval for darbepoetin alfa to QM represents a major potential benefit to both patients with CKD and their caregivers.

Inclusion Criteria

Inclusion Criteria: - Diagnosis of CKD and not expected to initiate dialysis for the duration of the study - Estimated glomerular filtration rate (eGFR): greater than or equal to 15 mL/min and less than or equal to 60 mL/min measured by the following modified Modification of Diet in Renal Disease (MDRD) equation 9, 10 : eGFR = 186 x \[serum creatinine\]-1.154 x \[Age\]-0.203 x \[0.742 if subject is female\] x \[1.212 if subject is black\] - Clinically stable, in the judgment of the investigator - Mean Hb greater than or equal to 11.0 g/dL to less than or equal to 13.0 g/dL (mean of 2 values drawn at least 3 days apart during the screening period) - Transferrin saturation (Tsat) greater than or equal to 15.0% - Serum vitamin B12 and folate levels above the lower limit of the normal range - Receiving stable Q2W subcutaneous (SC) doses of Aranesp® (darbepoetin alfa).

Exclusion Criteria
