Brief summary:
Study evaluating the efficacy and safety of intravenous (IV) ferumoxytol compared with oral iron for the treatment of pediatric participants with chronic kidney disease (CKD).

Detailed description:
Study AMAG-FER-CKD-251 was a study evaluating the efficacy and safety of IV ferumoxytol in pediatric participants with dialysis-dependent CKD. Study AMAG-FER-CKD-252 (NCT01155388) was a study evaluating the efficacy and safety of IV ferumoxytol in pediatric participants with nondialysis-dependent CKD. Due to significant challenges with enrollment for both studies, Study AMAG-FER-CKD-252 was combined with Study AMAG-FER-CKD-251 and enrollment continued under Study AMAG-FER-CKD-251. The enrollment number (n=14) includes the number of participants for both AMAG-FER-CKD-251 and AMAG-FER-CKD-252 studies, combined.

Participants were enrolled by age cohorts in a stepwise manner following a safety review by the Data Safety Monitoring Board of 1 age cohort prior to enrollment of a subsequent age cohort, with progression from oldest to youngest: Randomization was stratified by the following age cohorts: 12 to \<18 years, 6 to \<12 years, 2 to \<6 years, and 6 months to \<2 years.

Arms:
arm 1: Participants will receive 1 of the following 2 ferumoxytol dose regimens:

* Four IV injections of ferumoxytol 3.5 mg Fe/kg (maximum of 255 mg/dose) administered on nonconsecutive days within a 14-day period as follows: Day 1 (dose 1), Days 3\* through 10 (dose 2), Days 5 through 12 (dose 3), and Days 7 through 14 (dose 4). \*Participants participating in PK sampling received the second dose on Day 4 after the 72-hour PK sample was collected.
* Two IV injections of ferumoxytol 7.0 mg Fe/kg (maximum of 510 mg/dose), the first administered on Day 1 and the second on Days 3 through 9. arm 2: Participants will receive oral iron 2.5 mg Fe/kg twice daily (maximum of 100 mg/dose) on Days 1 through 35.

Interventions: intervention 1: Ferumoxytol intervention 2: Oral Iron
