Intravenous Ferric Carboxymaltose vs IV Iron Sucrose or IV Iron Dextran in Treating Iron Deficiency Anemia in Women

This was a Phase 2a, open-label, multicenter, randomized study that compared the safety and oxidative stress potential of FCM vs. IV iron sucrose or IV iron dextran in female subjects with IDA. Subjects with a diagnosis of IDA who required iron supplementation met all inclusion and no exclusion criteria, and had given informed consent were randomized. The duration of the study for each subject was a maximum of 6 weeks. Eligible subjects were randomized in a 1:1 ratio to FCM (Group A) or IV iron sucrose or IV iron dextran (Group B). Group A subjects received a single undiluted dose of iron as FCM by a slow IV injection on Day 0. Cohort I received 500 mg and Cohort II received 750 mg. Group B subjects received a single dose of iron as IV iron sucrose or as IC iron dextran on Day 0. Cohort I receive 500 mg iron sucrose and Cohort II received 750 mg iron dextran. Iron dextran administration was preceded by a 25 mg test dose 1 hour prior to infusion. All subjects had laboratory assessments at Baseline, 2 hours post-infusion, 24 hours post-infusion, Day 7 (drawn at the same time of day \[within 4 hours\] as the 24-hour visit), and Day 30 (drawn at the same time of day \[within 4 hours\] as the the 24-hour visit). On Days 7 and 30, the safety evalutation for all subjects included treatment-emergent adverse event reporting, concomitant medication review, physical examination including vital signs, and laboratory assessments. Any subject who withdrew from the study received a follow-up phone call 30 days after they received study drug.
