Abstract
Ferric derisomaltose (FDI) is an intravenous (IV) high-dose iron formulation approved in the US for the treatment of iron deficiency anemia in adults who are intolerant of/have had an unsatisfactory response to oral iron, or who have non-dialysis-dependent chronic kidney disease (NDD-CKD). FERWON-NEPHRO was a randomized, open-label, multicenter clinical trial evaluating the safety and efficacy of a single infusion of FDI 1,000 mg versus up to 5 doses of iron sucrose (IS) 200 mg (recommended cumulative dose, 1,000 mg) over 8 weeks in patients with NDD-CKD and iron deficiency anemia. Of 1,525 patients included in the safety analysis, 244 (16%) had a history of heart failure (HF). Overall, the rate of serious or severe hypersensitivity reactions was low and did not differ between treatment groups. Cardiovascular adverse events (AEs) were reported for 9.4% of patients who had HF and 4.2% who did not. Time to first cardiovascular AE was longer following administration of FDI compared with IS (hazard ratio: 0.59 [95% CI: 0.37, 0.92]; p=0.0185), a difference that was similar in patients with or without HF (p=0.908 for interaction). Patients achieved a faster hematological response (assessed by changes in hemoglobin and ferritin concentrations, and increase in transferrin saturation) with FDI versus IS. In conclusion, in patients with NDD-CKD, a single infusion of FDI was safe, well tolerated, and was associated with fewer cardiovascular AEs and a faster hematological response, compared to multiple doses of IS. These effects were similar for patients with and without HF.

Abstract
AIMS: Patients with heart failure (HF) and iron deficiency experience poor health-related quality of life (HRQoL). We evaluated the impact of intravenous (IV) ferric carboxymaltose (FCM) vs. placebo on HRQoL for the AFFIRM-AHF population. METHODS AND RESULTS The baseline 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12), which was completed for 1058 (535 and 523) patients in the FCM and placebo groups, respectively, was administered prior to randomization and at Weeks 2, 4, 6, 12, 24, 36, and 52. The baseline KCCQ-12 overall summary score (OSS) mean ± standard error was 38.7 ± 0.9 (FCM group) and 37.1 ± 0.8 (placebo group); corresponding values for the clinical summary score (CSS) were 40.9 ± 0.9 and 40.1 ± 0.9. At Week 2, changes in OSS and CSS were similar for FCM and placebo. From Week 4 to Week 24, patients assigned to FCM had significantly greater improvements in OSS and CSS scores vs. placebo [adjusted mean difference (95% confidence interval, CI) at Week 4: 2.9 (0.5-5.3, P = 0.018) for OSS and 2.8 (0.3-5.3, P = 0.029) for CSS; adjusted mean difference (95% CI) at Week 24: 3.0 (0.3-5.6, P = 0.028) for OSS and 2.9 (0.2-5.6, P = 0.035) for CSS]. At Week 52, the treatment effect had attenuated but remained in favour of FCM. CONCLUSION In iron-deficient patients with HF and left ventricular ejection fraction ≤50% who had stabilized after an episode of acute HF, treatment with IV FCM, compared with placebo, results in clinically meaningful beneficial effects on HRQoL as early as 4 weeks after treatment initiation, lasting up to Week 24.

Abstract
AIM: The aim of this study was to evaluate the benefits and safety of long-term i.v. iron therapy in iron-deficient patients with heart failure (HF). METHODS AND RESULTS CONFIRM-HF was a multi-centre, double-blind, placebo-controlled trial that enrolled 304 ambulatory symptomatic HF patients with left ventricular ejection fraction <45%, elevated natriuretic peptides, and iron deficiency (ferritin <100 ng/mL or 100-300 ng/mL if transferrin saturation <20%). Patients were randomized 1 : 1 to treatment with i.v. iron, as ferric carboxymaltose (FCM, n = 152) or placebo (saline, n = 152) for 52 weeks. The primary end-point was the change in 6-min-walk-test (6MWT) distance from baseline to Week 24. Secondary end-points included changes in New York Heart Association (NYHA) class, Patient Global Assessment (PGA), 6MWT distance, health-related quality of life (QoL), Fatigue Score at Weeks 6, 12, 24, 36, and 52 and the effect of FCM on the rate of hospitalization for worsening HF. Treatment with FCM significantly prolonged 6MWT distance at Week 24 (difference FCM vs. placebo: 33 +/- 11 m, P = 0.002). The treatment effect of FCM was consistent in all subgroups and was sustained to Week 52 (difference FCM vs. placebo: 36 +/- 11 m, P < 0.001). Throughout the study, an improvement in NYHA class, PGA, QoL, and Fatigue Score in patients treated with FCM was detected with statistical significance observed from Week 24 onwards. Treatment with FCM was associated with a significant reduction in the risk of hospitalizations for worsening HF [hazard ratio (95% confidence interval): 0.39 (0.19-0.82), P = 0.009]. The number of deaths (FCM: 12, placebo: 14 deaths) and the incidence of adverse events were comparable between both groups. CONCLUSION Treatment of symptomatic, iron-deficient HF patients with FCM over a 1-year period resulted in sustainable improvement in functional capacity, symptoms, and QoL and may be associated with risk reduction of hospitalization for worsening HF (ClinicalTrials.gov number NCT01453608).Copyright The Author 2014.
