A Study to Characterize the PK and PD Profile of IV FCM in Pediatric Subjects 1-17 Years Old With IDA

This is a Phase II, open-label, non-randomized, multi-center, single arm study to characterize the pharmacokinetic and pharmacodynamics (PK/PD) profile of Ferric Carboxymaltose dosing in pediatric subjects with IDA after receiving either a 7.5 mg/kg or 15 mg/kg dose of Ferric Carboxymaltose.

Inclusion criteria

• Male or female subjects 1 to 17 years of age with assent to participation and his/her parent or guardian is willing and able to sign the informed consent approved by the Independent Review Board / Ethics Committee.
• Screening TSAT < 20%
• Screening Hemoglobin < 11 g/dL
• For subjects who are receiving an erythropoietin stimulating agent (ESA): stable ESA therapy (+/- 20% of current dose) for > 8 weeks prior to the qualifying screening visit and no ESA dosing or product changes anticipated for the length of the trial

Exclusion criteria

• Known hypersensitivity reaction to any component of Ferric Carboxymaltose.
• Subject previously randomized and treated in this study or any other clinical study of Ferric Carboxymaltose (FCM or VIT-45).
• Body mass index (BMI) ≤ 5th percentile for age (see APPENDIX 2)
• Male or Female subject 1 year of age weighing < 12kg.
• History of acquired iron overload, hemochromatosis or other iron accumulation disorders.
• Chronic kidney disease subjects on hemodialysis.
• Screening Ferritin level > 300ng/mL
• Subjects with significant severe diseases of the liver, hemopoietic system, cardiovascular system, psychiatric disorder or other conditions which on the opinion of the investigator may place a subject at added risk.

• Intravenous iron and /or blood transfusion in the 4 weeks prior to screening.
• Immunosuppressive therapy that may lead to anemia (i.e. cyclophosphamide, azathioprine, mycophenolate mofetil). Note steroid therapy is permitted.
• Administration and / or use of an investigational product (drug or device) within 30 days of screening.
• Alcohol or drug abuse within the past six months.
