The primary objective of this study is to assess the safety of an investigational
intravenous iron (ferric carboxymaltose [FCM]) or an equal dose of iron dextran and explore
the mechanism of hypophosphatemia following administration of FCM or that of an equal dose
of iron dextran when treating women with iron deficiency anemia due to heavy uterine
bleeding (HUB).
Proportion of subjects achieving a hemoglobin increase > or = to 2 g/dL.Percent of subjects with treatment-emergent adverse events.
Occurrence of treatment-emergent serious adverse events.
Occurrence of treatment-emergent potentially clinically significant (PCS) values for routine clinical laboratory tests.
Occurrence of treatment-emergent PCS vital sign values.
Change from baseline to highest hemoglobin.
Change from baseline to highest ferritin.
Change from baseline to highest TSAT.
Minimum age: 18 Years.
Maximum age: N/A.
Gender(s): Female.
Inclusion Criteria:
- Female subjects > or = to 18 years of age
- History of Heavy Uterine Bleeding within the past 6 months
- Screening visit central laboratory Hgb < 12 g/dL
- Screening Visit ferritin < or = to 100 ng/mL or < or = to 300 when TSAT is < or = to
30%
- Demonstrate the ability to understand the requirements of the study, willingness to
abide by study restrictions and to return for the required assessments
Exclusion Criteria:

dextran

ml/min/1. 73m squared
- Previous kidney transplant
- History of primary hypophosphatemic disorder
- Hypophosphatemia < 2. 6 mg/dl
- No evidence of iron deficiency
- During the 10 day period prior to screening has been treated with intravenous iron
- During the 30 day period prior to screening or during the study period has or will be
treated with erythropoiesis stimulating agents (ESA) in a regimen that is off label
- During the 30 day period prior to screening or during the study period has or will be
treated with a red blood cell transfusion, radiotherapy and/or chemotherapy

require a surgical procedure that necessitates general anesthesia

determined by central labs, greater than 1. 5 times the upper limit of normal
- Known positive hepatitis with evidence of active disease
- Received an investigational drug within 30 days of screening
- Alcohol or drug abuse within the past 6 months
- Hemochromatosis or other iron storage disorders
- Malignancy history within the past 5 years other than basal or squamous cell skin
cancer
- Any other laboratory abnormality, medical condition or psychiatric disorders which in
the opinion of the investigator would put the subject's disease management at risk or
may result in the subject being unable to comply with study requirements

are not willing to use an acceptable form of contraception
- Untreated primary hyperparathyroidism
