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.

Inclusion Criteria:

- Female subjects 18-50 years of age and able to give informed consent.

- If post-partum, at least 10 days post delivery at Day 0.

- Screening Visit local laboratory Hgb < or = to 10 g/dL or < or = to 12 g/dL with
symptoms (dizziness and/or fatigue).

- Screening Visit ferritin < or = to 100 ng/mL or < or = to 300 when TSAT is < or = to
30%.

- Documented unsatisfactory response or intolerance to oral iron.

Exclusion Criteria:

- Previous participation in a ferric carboxymaltose (FCM) clinical trial.

- Known hypersensitivity reaction to any component of ferric carboxymaltose, Venofer, or
Dexferrum.

- History of drug allergy or any history of rheumatoid arthritis or other autoimmune
diseases.

- Current anemia not attributed to iron deficiency.

- During the 10 day period prior to screening has been treated with antibiotics.

- Significant cardiovascular disease, including but not limited to myocardial infarction
or unstable angina within 6 months prior to study inclusion or current history of NYHA
Class III or IV congestive heart failure.

- Any other laboratory abnormality, medical condition or psychiatric disorder which in
the opinion of the investigator puts the subject's disease management at risk or may
result in the subject being unable to comply with study requirements.

- Night shift workers.

- Breastfeeding planned on or after Day 0.

- Pregnant or sexually-active female subjects who are of childbearing potential and who
don't use an acceptable form of contraception.
