Study to Evaluate Darbepoetin Alfa in Pediatric Subjects With Anemia Due to Chronic Kidney Disease

This study has been withdrawn prior to enrollment.
(Difficulty in recruitment. PDCO in the Day 30 summary report agrred to remove the PK study in children <1 year of age.)

The purpose of this study is to find out more about darbepoetin alfa in children less than 1 year of age with anemia (a decrease in red blood cells) due to kidney failure. This study will see if darbepoetin alfa is safe and well tolerated and whether it causes any side effects by taking blood samples and checking vital signs (heart rate, body temperature, and blood pressure tests) at specific times throughout the study. In addition, the study will evaluate the amount of darbepoetin alfa in the blood over time and look at special markers in the blood to evaluate how darbepoetin alfa works on anemia.

Darbepoetin alfa is approved by the United States Food and Drug Administration (FDA) and European Medicines Agency (EMA) for use in adults, but not for all ages of pediatric subjects. Therefore, studies need to be conducted in pediatric subjects (children) to determine the appropriate dose to use in younger children.

  • Area under the concentration curve (AUC) of darbepoetin alfa [ Time Frame: Assessed predose and at 6, 24, 48, 72, and 168 hours postdose ]
  • Terminal half-life (t½) of darbepoetin alfa [ Time Frame: Assessed predose and at 6, 24, 48, 72, and 168 hours postdose ]
  • Clearance (CL) of darbepoetin alfa [ Time Frame: Assessed predose and at 6, 24, 48, 72, and 168 hours postdose ]
  • Change in reticulocytes [ Time Frame: Assessed from baseline to day 8 ]
  • Change in reticulocytes [ Time Frame: Assessed from baseline to day 29 ]
  • Change in hemoglobin concentration [ Time Frame: Assessed from baseline to day 8 ]
