Trial to Evaluate the Utility of Serum Hepcidin Levels to Predict Response to Oral or IV Iron and to Compare Safety, Effect on Quality of Life, and Resource Utilization of Injectafer vs. Intravenous Standard of Care for the Treatment of Iron Deficiency Anemia (IDA) in an Infusion Center Setting

The main objective of this study is to compare the safety, effect on quality of life, and
resource utilization of Injectafer vs. intravenous (IV) iron standard of care (SOC) for the
treatment of iron deficiency anemia (IDA) in an infusion center setting. The study will also
assess the ability of baseline serum hepcidin levels to predict if subjects will have a
clinically meaningful hemoglobin response to oral iron therapy for 28 days or to IV iron
therapy.

Inclusion Criteria:

- Male or female subjects ≥ 18 years of age and able to give informed consent.

- Iron deficiency is the primary etiology of anemia.

- If using erythropoiesis stimulating agent (ESA), the subject must be using a dose
consistent with package insert that has been stable for at least 30 days.

- Doses of potential myelosuppressive medications have been stable for at least 30
days.

- Females at risk of pregnancy must agree to use an acceptable form of birth control
and have a negative serum or urine pregnancy test on the first day of dosing.

Exclusion Criteria:

- Hypersensitivity reaction to any component of Injectafer.

- Requires dialysis for treatment of chronic kidney disease (CKD).

- 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 has been treated with a red red blood
cell transfusion.

- Any non-viral infection.

- 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.

- Estimated life expectancy of less than 6 months, or for cancer patients, an ECOG
Performance Status greater than 1.

- Pregnant or actively trying to become pregnant (a definitive negative result on a
serum or urine pregnancy test performed on the first day of dosing will be required
for study enrollment by any women of childbearing potential).

- 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.
