Key Inclusion Criteria for this study include:
- Males or females 6 months to <18 years of age
- Nondialysis dependent CKD, including kidney transplant recipients
- Has iron deficiency anemia defined as: a) hemoglobin level <11.0 grams (g)/deciliter (dL) and b) transferrin saturation level <20%
- Female participants of childbearing potential who are sexually active must be on an effective method of birth control for at least 1 month prior to Screening and agree to remain on birth control until completion of participation in the study

Ferumoxytol
Oral Iron
Arm Description
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.
Participants will receive oral iron: 2.5 mg Fe/kg twice daily (maximum of 100 mg/dose) on Days 1 through 35.
Outcomes
Primary Outcome Measures
Mean Change In Hemoglobin From Baseline To Week 5
Mean changes in hemoglobin from Baseline to Week 5 were to be presented. Despite efforts to complete the studies as designed, several factors contributed to significant challenges in enrollment and led the sponsor to discontinue the combined AMAG FER-CKD-252 and AMAG FER-CKD-251 studies. Blood samples were collected, but not run through an analysis to obtain outcome measure data. As such, the data set for this primary outcome measure cannot be summarized nor can the statistical analysis, as described in the protocol, be provided in a way that will provide any significant data based upon the limited study datasets.
Secondary Outcome Measures
Pharmacokinetics: Area Under The Curve Of Ferumoxytol
Ferumoxytol concentrations were to be determined using a drug-specific nuclear magnetic resonance assay. Blood samples were to be collected at specified times predose and postdose at the time of the first dose from 6 participants in each age-dose group. Sampling for participants <6 years of age will be minimized to the fewest number of time points required for population PK analysis based on preliminary PK data from the first 2 age cohorts. Blood samples were collected, but not run through an analysis to obtain outcome measure data. As such, the data set for this secondary outcome measure cannot be summarized in a way that will provide any significant data based upon the limited study datasets.

5. Study Description
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-252 was a study evaluating the efficacy and safety of IV ferumoxytol in pediatric participants with nondialysis-dependent CKD. Study AMAG-FER-CKD-251 (NCT01155375) was a study evaluating the efficacy and safety of IV ferumoxytol in pediatric participants with dialysis-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.
