Interventions

  • Drugdarbepoetin alfa SF

    Frequency of dosing depends on frequency at randomization: rHuEPO QW = darbepoetin alfa SF Q2W (dosing conversion table in protocol) rHuEPO biw or tiw = darbepoetin alfa SF QW (dosing conversion table in protocol) darbepoetin alfa RB = darbepoetin alfa SF at same dose and frequency PFS 10, 15, 20, 30, 40, 50, 60, 80, 100, 150, 200 or 300 mcg; Hb maintained between 11.0 - 13.0 g/dL
