The proposed study is designed to test a novel dosing paradigm that would facilitate the treatment of anemia in CKD patients on dialysis. Anemic patients on hemo and peritoneal dialysis who have achieved and maintained target hemoglobin (Hb) on every other week (Q2W) dosing of darbepoetin alfa will have the dosing interval extended to once monthly (QM) dosing.

Further study details as provided by Amgen:

Primary Outcome Measures:
  • The proportion of subjects on QM darbepoetin alfa dosing maintained with a mean Hb greater than or equal to 11.0 g/dL and less than or equal to 13.0 g/dL during the evaluation phase [ Time Frame: entire study ]

Secondary Outcome Measures:
  • Hb values over the duration of the study [ Time Frame: entire study ]
  • Darbepoetin alfa doses over the duration of the study [ Time Frame: entire study ]
  • Frequency and relationship to treatment for adverse events and changes in laboratory parameters and blood pressure [ Time Frame: entire study ]
