简要总结
This is a Phase 3, randomized, open-label, multicenter, study in male and female pediatric subjects (2 years to <18 years of age) with IDA, or felt by their clinician to be at risk of developing IDA. This study allows for enrollment of subjects with IDA regardless of etiology, except for CKD subjects (pediatric CKD subjects are being studied in a separate ferumoxytol protocol).
详细描述
Subjects will be randomized to treatment in a 2:1 ratio (ferumoxytol: iron sucrose) and stratified by age group (2 to \<6 years; 6 to \<12 years; and 12 to \<18 years). Subjects will receive one of the following treatment regimens: • Ferumoxytol: 7 mg Fe/kg IV (maximum 510 mg/dose) x 2 doses, the first dose administered on Day 1 and the second 2 to 8 days later. OR • Iron sucrose (Venofer®): 4 mg Fe/kg IV (maximum 200 mg/dose) x 5 doses, the first dose on Day 1 and subsequent doses administered at least once per week and up to 3 times/week. All subjects will be monitored at the study site through at least 1 hour after the completion of each infusion of study drug. Assessment of blood Hgb concentrations, adverse events, and other safety assessments will be performed through study Week 5.

研究组 & 干预措施
Ferumoxytol
Each 20 mL single-use vial contains 17 mL of ferumoxytol that consists of iron at a concentration of 30 mg Fe/mL, coated with polyglucose sorbitol carboxymethylether and formulated with mannitol, at a concentration of 44 mg/mL, in a black to reddish brown sterile, aqueous, colloidal, isotonic solution.
干预措施: ferumoxytol
Iron sucrose
Each mL contains 20 mg of elemental iron as iron sucrose in water for injection. The 5 mL single-use vial contains 100 mg of iron per 5 mL. The drug product contains approximately 30% sucrose (300 mg/mL)
干预措施: Iron sucrose
