Brief summary:
Study AMAG-FER-CKD-253 is an extension study of the combined AMAG-FER-CKD-251 (NCT01155375) and AMAG-FER-CKD-252 (NCT01155388) studies to evaluate the efficacy and safety of episodic treatment of iron deficiency anemia (IDA) with ferumoxytol.

Detailed description:
Study AMAG-FER-CKD-251 was a study evaluating the efficacy and safety of intravenous (IV) ferumoxytol in pediatric participants with dialysis-dependent chronic kidney disease (CKD). Study AMAG-FER-CKD-252 was a study evaluating the efficacy and safety of IV ferumoxytol in pediatric participants with nondialysis-dependent chronic kidney disease.

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.

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.

Participants who completed the combined AMAG-FER-CKD-251 and AMAG-FER-CKD-252 studies had the option of participating in this extension study.

Arms:
arm 1: When a participant has persistent or recurrent IDA (defined as hemoglobin \<12.0 grams \[g\]/deciliter \[dL\] and with either transferrin saturation \<40% or ferritin \<100 nanograms/milliliter), the participant will begin a 7-week treatment period. Participants will receive 2 IV injections of ferumoxytol 7.0 milligrams (mg) iron/kilogram (maximum of 510 mg/dose), the first dose administered on Day 1 and the second on Days 3 through 9 of the Treatment Period.

Interventions: intervention 1: Ferumoxytol
Intervention descriptions: intervention 1: IV Ferumoxytol
