E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety of ferumoxytol (7 mg Fe/kg [maximum 510 mg/dose] x 2 doses) in pediatric subjects with iron deficiency anemia (IDA). |
|
E.2.2 | Secondary objectives of the trial |
To determine the single-dose pharmacokinetics (PK) profile and describe the efficacy of ferumoxytol in pediatric subjects. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female 2 years to <18 years of age at time of consent 2. Has IDA at Screening defined as: a) Hemoglobin (Hgb) <11.0 g/dL AND b) Any one or more of the following: • Transferrin saturation (TSAT) <20% • ferritin <100 ng/mL 3. Documented history of unsatisfactory oral iron therapy or in whom oral iron cannot be tolerated, or for whom oral iron is considered medically inappropriate 4. If sexually active and of childbearing potential (for both male and female subjects), be on an effective method of birth control for at least 1 month prior to Day 1 and agree to remain on birth control until completion of the study 5. Subject and legal guardian is capable of understanding and complying with the protocol requirements and is available for the duration of the study 6. Subject and legal guardian has been informed of the investigational nature of this study; legal guardian has given voluntary written informed consent and, if appropriate, the subject has provided ‘assent’ in accordance with institutional, local, and national personal health data protection guidelines

E.4 | Principal exclusion criteria |
1. Known hypersensitivity reaction to any component of ferumoxytol or iron sucrose 2. History of allergy to intravenous (IV) iron 3. History of ≥2 clinically significant drug allergies 4. Subjects with CKD (defined as eGFR of <60 mL/min/1.73 m2 or a requirement for chronic hemodialysis or peritoneal dialysis during Screening) 5. Low systolic blood pressure (BP) (age 1 to 9 years <70 + [age in years x 2] mmHg, age 10 to 17 years <90 mmHg) 6. Hgb ≤7.0 g/dL 7. Serum ferritin level >600 ng/mL 8. Parenteral iron therapy or blood transfusion within 4 weeks prior to Screening or planned for administration during the study 9. ESA therapy within 4 weeks prior to Screening, or planned for administration during the study 10. Known causes of anemia other than iron deficiency (e.g. vitamin B12 or folate deficiency, hemolytic anemia, etc.) 11. Major surgery or invasive intervention within 4 weeks prior to Screening, or planned during the course of the study 12. Active malignancy within 2 years prior to Screening (except non-melanoma skin cancer or carcinoma in situ that has been excised) 13. Active clinically significant infection (e.g., systemic bacterial infection) or acute serious medical illness requiring treatment or intervention within 2 weeks prior to Screening 14. Received another investigational agent within 4 weeks prior to Screening, or planned receipt of an investigational agent not specified by this protocol during the study 15. Female subjects who are pregnant or intend to become pregnant, are breastfeeding, are within 3 months postpartum, or have a positive pregnancy test 16. Any other clinically significant condition or subject responsibility that, in the Investigator’s opinion, may interfere with a subject’s (and/or legal guardian’s) ability to adhere to the protocol, interfere with assessment of the investigational product, or serve as a contraindication to the subject’s participation in the study |

E.5.2.1 | Timepoint(s) of evaluation of this end point |
Efficacy endpoint: Week 5
PK endpoint: PK blood samples will be collected 10 minutes prior to administering the first dose; at 18 minutes (not before infusion ends and no later than 10 minutes after infusion ends), 1 hour (±15 minutes), 3 hours (±30 minutes), 5 hours (±30 minutes), 24 hours (±2 hours), and 48 hours (±4 hours) after the start of the infusion.
