Treatment for Subjects With Chronic Kidney Disease Receiving Haemodialysis

Phase 3

Completed

• Conditions: Kidney Disease

• Registration Number: NCT00116701
• Lead Sponsor: Amgen

Brief Summary

Treatment period 1:To demonstrate that switching HD subjects with a baseline haemoglobin (Hb) ≥ 10 g/dL and ≤ 13 g/dL from either subcutaneous (SC) or intravenous (IV) rHuEPO to IV darbepoetin alfa results in a mean Hb \> 11 g/dL.

Treatment Period 2:To demonstrate that switching subjects with a Hb \> 11 g/dL and ≤ 13 g/dL from once weekly IV darbepoetin alfa to once every 2 weeks (Q2W) maintains the mean Hb at \> 11 g/dL.
