NCT01719146
First received: October 29, 2012
Last updated: November 30, 2015
Last verified: November 2015
  Purpose
The purpose of this study is to prospectively collect data on doses of Erythropoietic Stimulating Agents and Intravenous Iron, and the markers of erythropoietic activity and iron status. These data will be used to derive mathematical models which will subsequently guide dosing of both agents, such that a desired therapeutic outcome is achieved in every patient, while minimizing patient exposure to both agents.

Groups/Cohorts Assigned Interventions
UofL Subjects
Subjects undergoing Specimen Collection at University Kidney Center, University of Louisville, Louisville, KY
Other: Specimen collection
At the beginning of each midweek hemodialysis session, a blood specimen (4 mL) will be drawn from the study subject. Out of this specimen a 1 mL serum sample will be frozen and stored. A 3 mL blood sample will be shipped overnight to WNERTA for laboratory testing.
Duke Subjects
Subjects undergoing Specimen Collection at Duke University, Durham, NC
Other: Specimen collection
At the beginning of each midweek hemodialysis session, a blood specimen (4 mL) will be drawn from the study subject. Out of this specimen a 1 mL serum sample will be frozen and stored. A 3 mL blood sample will be shipped overnight to WNERTA for laboratory testing.
WNERTA Subjects
Subject undergoing Specimen Collection at Western New England Renal and Transplant Associates, Springfield, MA
Other: Specimen collection
At the beginning of each midweek hemodialysis session, a blood specimen (4 mL) will be drawn from the study subject. Out of this specimen a 1 mL serum sample will be frozen and stored. A 3 mL blood sample will be shipped overnight to WNERTA for laboratory testing.

Detailed Description:

Data will be collected from 120 subjects undergoing hemodialysis treatment at 3 clinical sites across United States (40 per site).5.5 mL blood specimen will be drawn during midweek treatment (Wed/Thu) to measure:

Hemoglobin Concentration Hematocrit Red Blood Cell Count Platelet Count Reticulocyte Percentage Reticulocyte Hemoglobin Mean Cellular Hemoglobin Mean Cellular Hemoglobin Concentration Mean Cell Volume Red Cell Volume Distribution Width Mean Platelet Volume Serum Iron Serum Ferritin Transferrin Saturation Hepcidin Soluble Transferrin Receptor

Weekly ESA and Iron dose delivered will also be recorded.

From these data:

  1. a mathematical model will be established to find biomarkers most descriptive with respect to erythropoiesis-iron synergy,
  2. a mathematical model will be established to correlate iron dose with iron markers.
