NCT00111098

Brief Summary

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.
