研究组 & 干预措施
Ferumoxytol
Participants received an 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).
干预措施: Ferumoxytol (Drug)
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.
干预措施: Iron Sucrose (Drug)
结局指标
主要结局
Mean Change In Hemoglobin From Baseline (Day 1) To Week 5
时间窗: Baseline (Day 1), Week 5
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.
Percentage Of Participants With An Increase In Hemoglobin ≥1.0 g/dL From Day 1 (Baseline) To Week 5
时间窗: Baseline (Day 1) and up to Week 5
The percentage of participants who achieved a ≥1.0 g/dL increase in hemoglobin at any time from Baseline (Day 1) up to Week 5 by treatment group is presented by study visit. Baseline hemoglobin for each participant was the Day 1 hemoglobin value (prior to injection of the study drug).
