Multicentre randomized controlled trial comparing ferric(III)carboxymaltose infusion with oral iron supplementation in the treatment of preoperative anaemia in colorectal cancer patients.

ABSTRACT: BACKGROUND:At least a third of patients with a colorectal carcinoma who are candidate for surgery, are anaemic preoperatively. Preoperative anaemia is associated with increased morbidity and mortality. In general practice, little attention is paid to these anaemic patients. Some will have oral iron prescribed others not. The waiting period prior to elective colorectal surgery could be used to optimize a patients' physiological status. The aim of this study is to determine the efficacy of preoperative intravenous iron supplementation in comparison with the standard preoperative oral supplementation in anaemic patients with colorectal cancer. METHODS/DESIGN:In this multicentre randomized controlled trial, patients with an M0-staged colorectal carcinoma who are scheduled for curative resection and with a proven iron deficiency anaemia are eligible for inclusion. Main exclusion criteria are palliative surgery, metastatic disease, neoadjuvant chemoradiotherapy (5?×?5 Gy?=?no exclusion) and the use of Recombinant Human Erythropoietin within three months before inclusion or a blood transfusion within a month before inclusion. Primary endpoint is the percentage of patients that achieve normalisation of the haemoglobin level between the start of the treatment and the day of admission for surgery. This study is a superiority trial, hypothesizing a greater proportion of patients achieving the primary endpoint in favour of iron infusion compared to oral supplementation. A total of 198 patients will be randomized to either ferric(III)carboxymaltose infusion in the intervention arm or ferrofumarate in the control arm. This study will be performed in ten centres nationwide and one centre in Ireland. DISCUSSION:This is the first randomized controlled trial to determine the efficacy of preoperative iron supplementation in exclusively anaemic patients with a colorectal carcinoma. Our trial hypotheses a more profound haemoglobin increase with intravenous iron which may contribute to a superior optimisation of the patient's condition and possibly a decrease in postoperative morbidity.

Project description:BackgroundIron deficiency anaemia (IDA) is a major health issues and common type of nutritional deficiency worldwide. For IDA treatment, intravenous (IV) iron is a useful therapy.ObjectiveTo determine the efficacy and cost-effectiveness (CE) of intravenous (IV) Ferric Carboxymaltose (FCM) versus IV Iron Sucrose (IS) in treating IDA.Data sourcesElectronic medical record i.e. Cerner® system.Target populationAdults patients with iron deficiency anaemia.Time horizonA 12-month period (01/01/2018-31/12/2018).PerspectiveHamad Medical Corporation (HMC, a public hospital).InterventionIV Ferric Carboxymaltose versus IV Iron Sucrose.Outcome measuresWith regard to responses to treatment i.e., efficacy of treatment with FCM & IS in IDA patients, hemoglobin (Hgb), ferritin, and transferrin saturation (TSAT) levels were the primary outcomes. Additionally, the researchers also collected levels of iron, platelet, white blood cell (WBC), red blood cell (RBC), mean corpuscular hemoglobin (MCH), and mean corpuscular volume (MCV). The costs i.e. resources consumed (obtained from NCCCR-HMC) and the CE of FCM versus IS were the secondary outcomes.Results of base-case analysisThere was a significant improvement in Hgb, RBC and MCH levels in the IS group than the FCM group. The overall cost of IS therapy was significantly higher than FCM. The medication cost for FCM was approximately 6.5 times higher than IS, nonetheless, it is cheaper in terms of bed cost and nursing cost. The cost effectiveness (CE) ratio illustrated that FCM and IS were significantly different in terms of Hgb, ferritin and MCH levels. Further, Incremental Cost Effectiveness Ratio (ICER) indicated that further justifications and decisions need to be made for FCM when using Hgb, iron, TSAT, MCH and MCV levels as surrogate outcomes.Results of sensitivity analysisNot applicable.LimitationsThe study did not consider the clinical or humanistic outcome.ConclusionsThe higher cost of FCM versus IS can be offset by savings in healthcare personnel time and bed space. ICER indicated that further justifications and decisions need to be made for FCM when using Hgb, iron, TSAT, MCH and MCV levels as surrogate outcomes.

Project description:In this multi-centre, prospective, non-interventional study, the effectiveness and tolerance of ferric carboxymaltose (ferinject®; FCM) was tested through use in standard gynaecological practice. In total, data from 273 patients was evaluated. 193 of these patients displayed iron deficiency anaemia (IDA), and 68 had iron deficiency without anaemia (ID). The reasons for the ID/IDA were hypermenorrhoea (HyM) (n = 170), post-partum condition (PP) (n = 53) or another indication (n = 53). The average age of the patients was 40 years old, with 8 % of them being vegetarians. Half of the patients had already been treated for anaemia, primarily with oral iron products (94 %). The primary, serious accompanying symptoms of anaemia were fatigue (72 %), lack of concentration (42 %), pale mucous membranes (42 %), headache (26 %) and sleep disorders (21 %). Only one patient did not show serious symptoms at the start of the study. The most frequent indications for parenteral therapy were the need for rapid iron substitution to reduce symptoms (> 70 %), followed by the lower effectiveness or intolerance of oral products (42 % each) as well as patients not completing the course of treatment with oral products (12 %). Patient information was collected at both the beginning and the end of the observation period, which lasted 15 weeks on average. FCM was most frequently administered via infusion (92 %; average infusion duration 21 minutes). Seven percent of patients received bolus injections. The average total iron dosage per patient was 788.7 mg (median 550 mg; range: 50-3000 mg); the median individual dosage was 500 mg (range: 50-1000 mg). The total dosage was, in most cases, administered through a single application (range: 1-10). Symptoms, blood values (Hb), iron stores (serum-ferritin [S-ferritin]) and transport iron (transferrin saturation [TSAT]) normalised to a large extent. In all subgroups, 92 % of women displayed a marked improvement in all of their symptoms. The average increase in Hb-value in the group as a whole was statistically significant, increasing from 10.5 to 13.0 g/dl. In the group with anaemia, the value increased from 9.9 to 13.3 g/dl, with 80 % of women reaching normal Hb-values. The average S-ferritin value increased by a statistically significant > 70 µg/L from 17.2 to 88.8 µg/l and the value for the TSAT increased from 16.3 % to 22.8 %. Seven patients reported experiencing side effects. None of the results were severe. Overall, as part of this non-interventional study for everyday routine in a gynaecological practice, a rapid improvement in symptoms accompanied by the rectification of iron deficiency and anaemia was shown with low occurrences of mild undesirable events, and therefore the data obtained from controlled clinical studies on the effectiveness and tolerance of intravenous ferric carboxymaltose could be confirmed.

Project description:BackgroundAnaemia affects 46% of pregnancies in Africa; oral iron is recommended by WHO but uptake and adherence are suboptimal. We tested a single dose of a modern intravenous iron formulation, ferric carboxymaltose, for anaemia treatment in Malawian pregnant women.MethodsIn this open-label, individually randomised controlled trial, we enrolled women with a singleton pregnancy of 13-26 weeks' gestation in primary care and outpatient settings across two regions in southern Malawi. Women were eligible if they had capillary haemoglobin of less than 10·0 g/dL and negative malaria rapid diagnostic test. Participants were randomised by sealed envelope 1:1. Assessors for efficacy outcomes (laboratory parameters and birthweight) were masked to intervention; participants and study nurses were not masked. Participants were given ferric carboxymaltose up to 1000 mg (given once at enrolment in an outpatient primary care setting), or standard of care (60 mg elemental iron twice daily for 90 days), along with intermittent preventive malaria treatment. The primary maternal outcome was anaemia at 36 weeks' gestation. The primary neonatal outcome was birthweight. Analyses were performed in the intention-to-treat population for mothers and liveborn neonates, according to their randomisation group. Safety outcomes included incidence of adverse events during infusion and all adverse events from randomisation to 4 weeks' post partum. The trial is registered with ANZCTR, ACTRN12618001268235. The trial has completed follow-up.FindingsBetween Nov 12, 2018, and March 2, 2021, 21 258 women were screened, and 862 randomly assigned to ferric carboxymaltose (n=430) or standard of care (n=432). Ferric carboxymaltose did not reduce anaemia prevalence at 36 weeks' gestation compared with standard of care (179 [52%] of 341 in the ferric carboxymaltose group vs 189 [57%] of 333 in the standard of care group; prevalence ratio [PR] 0·92, 95% CI 0·81 to 1·06; p=0·27). Anaemia prevalence was numerically lower in mothers randomly assigned to ferric carboxymaltose compared with standard of care at all timepoints, although significance was only observed at 4 weeks' post-treatment (PR 0·91 [0·85 to 0·97]). Birthweight did not differ between groups (mean difference -3·1 g [-75·0 to 68·9, p=0·93). There were no infusion-related serious adverse events or differences in adverse events by any organ class (including malaria; ≥1 adverse event: ferric carboxymaltose 183 [43%] of 430 vs standard of care 170 [39%] of 432; risk ratio 1·08 [0·92 to 1·27]; p=0·34).InterpretationIn this malaria-endemic sub-Saharan African setting, treatment of anaemic pregnant women with ferric carboxymaltose was safe but did not reduce anaemia prevalence at 36 weeks' gestation or increase birthweight.FundingBill & Melinda Gates Foundation (INV-010612).
