Primary Outcome Measures:
  • Proportion of subjects undergoing conversion to peginesatide injection [ Time Frame: 13 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

    Based on pre-specified dosing criteria

  • Hemoglobin levels [ Time Frame: 13 months ] [ Designated as safety issue: Yes ]
    Percentage of subjects with Hgb values within the Hgb range of 10-11 g/dl

  • Iron Utilization [ Time Frame: 13 months ] [ Designated as safety issue: Yes ]
    Total intravenous iron dose

  • Red Blood Cell Transfusion [ Time Frame: 13 months ] [ Designated as safety issue: Yes ]
    Percentage of subjects with red blood cell transfusions during the study

Arms Assigned Interventions
Experimental: peginesatide injection Drug: peginesatide injection
Intervention is a once monthly IV or subcutaneous dose of peginesatide injection.

Detailed Description:

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 will be conducted at 1-5 hemodialysis sites in the United States, and will enroll Chronic Kidney Disease (CKD) patients receiving outpatient, in-center hemodialysis. The study treatment period is intended to be approximately 12 months in duration. Subjects will receive peginesatide injection for approximately six months.
