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.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||14 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Randomized, Open-Label, Active-Controlled Study of the Safety, Efficacy, and Pharmacokinetics of Ferumoxytol Compared With Oral Iron for the Treatment of Iron Deficiency Anemia in Pediatric Subjects With Nondialysis-dependent Chronic Kidney Disease|
|Actual Study Start Date :||October 17, 2011|
|Primary Completion Date :||June 24, 2014|
|Study Completion Date :||June 24, 2014|
Participants will receive 1 of the following 2 ferumoxytol dose regimens:
Active Comparator: Oral Iron
Participants will receive oral iron: 2.5 mg Fe/kg twice daily (maximum of 100 mg/dose) on Days 1 through 35.
Drug: Oral Iron
Active Comparator: Oral iron
Other Name: Ferrous fumarate
- Mean Change In Hemoglobin From Baseline To Week 5 [ Time Frame: 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.
- Pharmacokinetics: Area Under The Curve Of Ferumoxytol [ Time Frame: Baseline; 10, 30, 120, and 360 minutes postdose; 24, 48, and 72 hours postdose ]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.
