Trial Outcomes & Findings for A Trial Comparing Ferumoxytol to Iron Sucrose for the Treatment of Iron Deficiency Anemia in Adult Subjects With Chronic Kidney Disease (NCT NCT01052779)

NCT ID: NCT01052779

Last Updated: 2023-07-25

Results Overview

The change in hemoglobin from Baseline (Day 1) to Week 5 was calculated for each participant as: Hemoglobin Change = Hemoglobin (Week 5) - Hemoglobin (Baseline) The least squares mean, with standard error, is reported as g/deciliter (dL). Baseline hemoglobin for each participant was the Day 1 hemoglobin value (prior to injection of the study drug). The screening hemoglobin value was used for any participants with missing Baseline (Day 1) hemoglobin. Analysis used last observed carried forward (LOCF) imputation methods for missing values for the ITT population. Sensitivity analyses were performed without imputation for missing data and with the Markov chain Monte Carlo method.

Measure
Ferumoxytol
Participants received an intravenous (IV) injection of ferumoxytol (510 milligrams \[mg\], 17 milliliters \[mL\]) on Day 1 (Baseline). This was followed by a second injection of ferumoxytol (510 mg, 17 mL) 5±3 days later for a total cumulative dose of 1.02 grams (g).
Iron Sucrose
Participants received iron sucrose based on hemodialysis status. Participants on hemodialysis received either slow IV injection or IV drip infusion of 100 mg of iron sucrose on Day 1 (Baseline) and at the following 9 consecutive hemodialysis sessions for a total cumulative dose of 1.0 g. Participants not on dialysis received either slow IV injection or IV drip infusion of 200 mg of iron sucrose on Day 1 (Baseline) and at 4 subsequent visits on nonconsecutive days over a 14-day period for a total cumulative dose of 1.0 g.
