A Study to Evaluate Ferumoxytol for the Treatment of Iron Deficiency Anemia (IDA) in Pediatric Subjects

A Phase 3, Randomized, Open-Label, Multicenter Study to Evaluate the Safety, Efficacy and Pharmacokinetics of Ferumoxytol for the Treatment of Iron Deficiency Anemia (IDA) in Pediatric Subjects

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).

Study Overview

• Status: Recruiting
• Conditions: Iron Deficiency Anemia
• Intervention / Treatment: Drug: ferumoxytol; Drug: Iron sucrose

Detailed Description

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.

• Study Type: Interventional
• Enrollment (Estimated): 75
