Secondary Outcome Measures:
  • Change from baseline Hb over time [ Time Frame: 29 weeks ]
  • Proportion of subjects maintaining mean Hb within target range during evaluation period [ Time Frame: 7 weeks ]
  • Average darbepoetin alfa dose over evaluation period [ Time Frame: 7 weeks ]
  • Change from baseline dose over time [ Time Frame: 29 weeks ]

Enrollment: 446

Study Completion Date: October 2006
Primary Completion Date: October 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Roller bottle Drug: Darbepoetin Alfa
Initial dose, frequency and route of administration of study drug will be the same as that administered for darbepoetin alfa prior to enrollment. Frequency either once a week or once every two weeks, frequency may not change for duration of study. Route of administration either subcutaneous or intravenous, route of administration may not change for duration of study. Study drug provided in pre-filled syringes at the following unit doses: 10, 15, 20, 30, 40, 50, 60, 80, 100 or 150 ug.
Experimental: Serum free Drug: Darbepoetin Alfa
Initial dose, frequency and route of administration of study drug will be the same as that administered for darbepoetin alfa prior to enrollment. Frequency either once a week or once every two weeks, frequency may not change for duration of study. Route of administration either subcutaneous or intravenous, route of administration may not change for duration of study. Study drug provided in pre-filled syringes at the following unit doses: 10, 15, 20, 30, 40, 50, 60, 80, 100 or 150 ug.
