简要总结
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).
详细描述
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.

研究组 & 干预措施
Ferumoxytol
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.
干预措施: Ferumoxytol (Drug)
Oral Iron
Participants will receive oral iron: 2.5 mg Fe/kg twice daily (maximum of 100 mg/dose) on Days 1 through 35.
干预措施: Oral Iron (Drug)
结局指标
主要结局
Mean Change In Hemoglobin From Baseline To Week 5
时间窗: Baseline, 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.
次要结局
- Pharmacokinetics: Area Under The Curve Of Ferumoxytol(Baseline; 10, 30, 120, and 360 minutes postdose; 24, 48, and 72 hours postdose)
