Brief summary
This is a open-label, uncontrolled, monocenter, phase IV study. The aim of this study is to detect AEs or SAEs with a relative frequency of at least 11.5% in LVAD patients with iron deficiency anemia treated with oral ferric maltol for 12 weeks.
Interventions
Feraccru® 30 mg hard capsules will be used. Each capsule contains 30 mg iron (as ferric maltol), 91.5 mg of lactose, 0.5 mg of Allura Red AC (E129) and 0.3 mg Sunset Yellow FCF (E110) as excipients with known effects
