Iron Indices and Intravenous Ferumoxytol: Time to Steady State

Phase 4
Completed
Conditions
Iron Deficiency Anemia
Interventions
Registration Number
NCT01148745
Lead Sponsor
Dialysis Clinic, Inc.
Brief Summary

The purpose of this study is to evaluate the time point of transferrin saturation (TSAT) and ferritin stabilization after a thirteen-treatment period following a ferumoxytol load, as well as to determine the point at which serum ferritin and TSAT concentrations can be checked in iron deficiency anemia (IDA) hemodialysis patients.

Primary Outcome Measures
NameTimeMethod
Number of Weeks Until Transferrin Saturation (TSAT) and Ferritin Stabilizepre-dosing/baseline, and 7 (visit 5), 14 (visit 8), 21 (visit 11) and 28 (visit 14) days after drug administration

TSAT,ferritin,and TIBC measured before start of dialysis on dosing days, and on next 13 HD treatments. Continuous variables were summarized using median. Paired continuous data (e.g., TSAT, serum ferritin) were compared using the Wilcoxon signed rank test. Analyses evaluating stabilization of post drug iron indices was determined by comparing consecutive values at consecutive dialysis sessions and when there was no longer a difference between 2 consecutive time points, levels were considered stabilized. P-values \<0.05 were considered statistically significant.

Secondary Outcome Measures
NameTimeMethod
Transferrin Saturation (TSAT)7 (visit 5), 14 (visit 8), 21 (visit 11), and 28 (visit14) days.

Transferrin saturation (TSAT) measured as a percentage, is a medical laborastory test. It is the ratio of serum iron and total iron-binding capacity, multiplied by 100

Serum Ferritin7 (visit 5), 14 (visit 8), 21 (visit 11) and 28 days (visit 14)

Serum ferritin values were measured at all visits
