Randomized Placebo-controlled Trial of FCM as Treatment for Heart Failure With Iron Deficiency
The primary objective of this study is to determine the efficacy and safety of iron therapy using intravenous (IV) ferric carboxymaltose (FCM), relative to placebo, in the treatment of participants in heart failure with iron deficiency and with a reduced ejection fraction.

a. Left ventricular ejection fraction ≤ 40% obtained during the screening visit OR either of the following i. Historical value of ejection fraction ≤ 40% within 24 months of screening visit ii. Historical value of ejection fraction ≤ 30% within 36 months of screening visit
5. Hemoglobin >9.0 g/dL and < 13.5 g/dL (females) or <15.0 g/dL (males) within 28 days of randomization.
6. Serum ferritin <100 ng/mL or 100 to 300 ng/mL with TSAT <20%.Patients with screening ferritin <15 ng/mL must have documentation of an appropriate evaluation, as determined by the Principle Investigator, within 3 months of screening and prior to randomization.
7. Either documented hospitalization for heart failure within 12 months of enrollment or elavated N-terminal-pro-brain natriuretic peptide (NT-proBNP) within 90 days of randomization. a. For patients in normal sinus rhythm: N-terminal-pro-brain natriuretic peptide (NT- proBNP) > 600 pg/mL (or BNP >200 pg/mL) . b . For patients in atrial fibrillation: NT-proBNP >1000 pg/mL (or BNP >400 pg/mL) .

This is a double-blind, multicenter, prospective, randomized, placebo-controlled study to assess the effects of IV FCM compared to placebo on the 12-month rate of death, hospitalization for worsening heart failure, and the 6-month change in 6 minute walk test (6MWT) for patients in heart failure with iron deficiency.
After an initial screening period of up to 28 days, eligible participants will be stratified by region and randomized in a 1:1 ratio to FCM or placebo for treatment.
Study drug administration will occur on Day 0 and Day 7 (±2) as an undiluted slow IV push, with additional study visits planned at 3 month intervals, and additional dosing administered every 6 months as applicable. In a subset of sites, a sub-study will be conducted to characterize serum phosphate levels overtime in participants with heart failure and iron deficiency after dosing with FCM. For all participants, hematology, ferritin, and transferrin saturation (TSAT), with appropriate safety evaluations, to determine additional treatment, will occur at 6 month intervals.
