|Chronic Kidney Disease Anemia||Drug: Epoetin Drug: Peginesatide||Phase 3|
Monthly Erythropoiesis-Stimulating Agents (ESA) dosing, compared with the longstanding practice of dosing three times per week, represents a significant change in anemia treatment for dialysis patients. Because of the differences in the processes needed to support monthly dosing versus thrice weekly dosing, there is a need to prospectively identify and evaluate factors in the dialysis environment during center-level transition of patients from one ESA to another.
AFX01-18 is a Phase 3b open-label, single-arm conversion study that was conducted at 5 hemodialysis sites in the United States, and enrolled Chronic Kidney Disease (CKD) patients receiving outpatient, in-center hemodialysis. The study treatment period was approximately 12 months in duration. Participants received peginesatide injection for approximately six months.

Experimental: peginesatide injection
In the first 6 months participants received standard of care treatment with epoetin (the Standard of Care Period [SCP]), followed by a 1-week erythropoiesis-stimulating agent (ESA)-Free Period, followed by peginesatide injection for 6 months (the Peginesatide Treatment Period [PTP]).
Commercially available epoetin alfa administered weekly, twice weekly, or thrice weekly at an initial starting dose, frequency of administration, and mode of administration (intravenous [IV] or subcutaneous [SC]) individually determined for each participant using the site's usual standard of care. Subsequent dose adjustments or dose holds may have been made in order to maintain a hemoglobin concentration of <11 g/dL.Drug: Peginesatide
Administered as a once monthly intravenous (IV) or subcutaneous (SC) injection. The initial dose of peginesatide injection was based on the final weekly dose of epoetin administered in the SCP; subsequent doses may have been adjusted in order to maintain hemoglobin concentrations at <11 g/dL.
