Overview

Non-commercial, multicentre, randomised, double-blind, parallel group, placebo-controlled clinical trial. Eligible patients were randomly assigned (1:1) using a secure, central, interactive, web-based response system, to intervention FCM or placebo arm. Time of observation: minimum of 8 months up to a maximum of 36 months.

Primary Study Objective: Primary:

Evaluation of the effect of i.v. FCM treatment compared with placebo on the risk of death, the risk of heart failure events (HFE*) (number of events and time to first event), NTproBNP concentration and the change in quality of life (QoL) assessed using EQ-5D during the follow-up up to 36-months in patients with recent AMI and ID (with an implementation of a win ratio approach in a hierarchical descending order).

*HFE: unplanned hospitalization for HF (including unplanned visit at emergency department due to HF), ambulatory significant intensification of diuretic therapy (either starting i.v. loop diuretic or more than doubling oral loop diuretic dose or de novo initiation of oral loop diuretic therapy due to HF signs/symptoms).

Eligibility

Inclusion criteria:

1. Age ≥18 years;
2. Diagnosis of AMI (STEMI or NSTEMI) up to 4 weeks (28 days) before randomisation
3. Presence of iron deficiency (ID) defined as transferrin saturation TSAT<20% assessed within up to 4 weeks (28 days) before randomisation;
4. Presence of ≥3 factors (confirmed within up to 4 weeks before randomisation) (note: at least one of a-c must be present):
   1. LVEF ≤50%;
   2. NT-proBNP ≥400 pg/mL for subjects in sinus rhythm and NT-proBNP ≥800 pg/mL for subjects with atrial fibrillation;
   3. Clinical features of congestion/volume overload (including Killip class II or more) requiring i.v. loop diuretic use;
   4. Diagnosis of diabetes mellitus (also de novo diagnosis);
   5. Diagnosis of atrial fibrillation (any time in the past or de-novo diagnosis);
   6. Multivessel coronary disease (regardless of completeness of revascularisation during an index AMI);
   7. Not complete revascularisation or/and no reperfusion (during an index AMI);
   8. History of AMI (despite an index AMI);
   9. eGFR <60 mL/min/1.73m2; 1. Age ≥70 years.
5. Written informed consent

Exclusion criteria:

1. Subject temperature >38 ͦ C or any infection requiring antibiotic therapy within 48 hours prior to randomisation;
2. Severe, symptomatic valve disorder;

4. Body weight <50 kg;
5. Haemoglobin <8 g/dL or >15,5 g/dL;
6. Serum ferritin >400 ng/mL;
7. Active gastroenteral bleeding;
8. Known hypersensitivity to any of the administered preparations;
9. Treatment with erythropoiesis stimulating factors, i.v. iron therapy or blood transfusion within 6 months prior to randomisation;
10. Subject has known active malignancy of any organ system, i.e., clinical evidence of current malignancy or not in stable remission for at least 3 years since completion of last treatment with exception of non-invasive basal cell carcinoma, squamous cell carcinoma of the skin or cervical intra-epithelial neoplasia;
11. Documented liver diseases;
12. Participation in a device or drug trial within 3 months prior to randomisation or 5 half-lives, whichever period is longer, prior to the screening visit;
13. Pregnancy or lactation;
14. Any situation that may prevent the test from being performed in accordance with the protocol, or the consent of the investigator to be given in writing, including alcohol, drugs or any other substance overuse or addiction.
