Zhang F, Shen A, Ahmed W, Pollock RF. A Cost-Utility Analysis of Ferric Derisomaltose Versus Ferric Carboxymaltose in Patients with Iron Deficiency Anemia in China. Adv Ther 2024:10.1007/s12325-024-02987-7. [PMID: 39292421 DOI: 10.1007/s12325-024-02987-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2024] [Accepted: 08/30/2024] [Indexed: 09/19/2024]
Abstract
INTRODUCTION Intravenous (IV) iron is the recommended treatment for patients with iron deficiency anemia (IDA) unresponsive to oral iron treatment, in whom oral iron is contraindicated, or where rapid iron replenishment is required. Ferric derisomaltose (FDI) and ferric carboxymaltose (FCM) are high-dose, rapid-infusion, IV iron formulations that have recently been compared in three head-to-head randomized controlled trials (RCTs), which showed significantly higher incidence of hypophosphatemia after administration of FCM than FDI. The present study objective was to evaluate the cost-utility of FDI versus FCM in a population of patients with IDA in China. METHODS A previously-published patient-level simulation model was used to model the cost-utility of FDI versus FCM in China. The number of infusions of FDI and FCM was modeled based on the approved posology of the respective formulations using simplified tables of iron need in a population of patients with body weight and hemoglobin levels informed by a Chinese RCT of FCM. Data on the incidence of hypophosphatemia was obtained from the PHOSPHARE-IDA RCT, while data on disease-related quality of life were obtained from SF-36v2 data from the PHOSPHARE-IBD RCT. RESULTS Over the 5-year time horizon, patients received 3.98 courses of iron treatment on average, requiring 0.90 fewer infusions of FDI than FCM (7.69 vs. 6.79). This resulted in iron procurement and administration cost savings of renminbi (RMB) 206 with FDI (RMB 3,519 vs. RMB 3,312). Reduced incidence of hypophosphatemia-related fatigue resulted in an increase of 0.07 quality-adjusted life years and further cost savings of RMB 782 over 5 years, driven by reduced need for phosphate testing and replenishment. FDI was therefore the dominant intervention. CONCLUSIONS The results showed that FDI would improve patient quality of life and reduce direct healthcare expenditure versus FCM in patients with IDA in China.

Abstract
OBJECTIVE To analyse the clinical efficacy and adverse drug reactions (ADRs) of iron preparations. METHODS A total of 374 patients with iron deficiency anaemia admitted to our hospital between 1 January and 31 December 2020 were included in this study. They were divided into 2 groups based on their medication regimens: Group A (n = 187) took oral ferrous succinate tablets, and Group B (n = 187) received intravenous iron sucrose. The remission of major symptoms, laboratory test results, ADRs and other related data were collected after 4 weeks of treatment. RESULTS Compared with the pre-treatment baseline, haemoglobin (Hb), serum iron (SI), serum ferritin (SF) and the mean corpuscular volume (MCV) increased in both groups at 4 weeks of treatment (P < 0.05). After treatment, Group A had lower levels of Hb (108.41 ± 8.39 vs. 122.31 ± 6.04 g/L, t = 6.293, P < 0.001), SI (9.72 ± 4.24 vs. 15.62 ± 5.41 µmol/L, t = 5.482, P < 0.001) and SF (27.1 ± 10.82 vs. 39.82 ± 10.44 ug/L, t = 6.793, P < 0.001) compared with Group B. In contrast, there was no significant difference in the post-treatment level of MCV (P > 0.05). The overall response rate significantly differed between the 2 groups (78.61% vs. 90.91%, χ2 = 10.949, P < 0.001). The incidence of ADRs of both groups were similar, and the difference was not statistically significant (χ2 = 0.035, P = 0.851). CONCLUSION Iron sucrose demonstrates favourable efficacy and safety in treating iron deficiency anaemia.

Abstract
Intravenous iron has become an essential component for the treatment of iron deficiency and iron deficiency anemia. Individuals administering Intravenous iron should have knowledge in intravenous iron administration, including a pre-infusion assessment to evaluate infusion reaction risks, pre- and post-infusion monitoring, identification of and management of infusion reactions, accurate documentation of these reactions, laboratory monitoring and recognition and management of treatment-emergent hypophosphatemia. This comprehensive consensus provides step-by-step guidance and tools for practitioners to promote safe delivery of intravenous iron, recognition, and management of infusion reactions and treatment-emergent hypophosphatemia.

Abstract
Introduction Anemia remains a prevalent global health issue with varying severity. Intravenous iron supplementation, particularly with ferric carboxymaltose (FCM), has appeared as a possible therapeutic intervention for individuals with moderate to severe anemia. The study aimed to assess the efficacy and safety of ferric carboxymaltose (FCM) in reducing anemia. Methods We searched electronic databases, registries, websites, e-libraries, reference lists of reviews, citations, etc. We included randomized control trials (RCTs), non-RCTs, and single-arm studies, while observational studies, case series, and case studies were excluded. Two reviewers independently screened the studies and extracted the data. We included studies of moderate-to-severely anemic Indians and excluded Indians with other comorbidities. We assessed the risk of bias and the overall quality of evidence (QoE) using GRADE GDT. Result We identified 255 studies and included 14 studies (11 RCT, one non-RCT, and two single-arm studies) with 1,972 participants for qualitative analysis and 10 studies in the meta-analysis. All the included studies detailed the use of FCM for anemia. The primary outcomes assessed in the included studies were anemia, hemoglobin, and adverse events. The outcomes assessed ranged from 2 weeks to 12 weeks. The risk of bias varied across different studies with different outcomes. FCM is consistent with a fewer number of adverse events as compared to other interventions and provides "moderate" to "very low" QoE. Conclusion A slow single infusion of 1 gram of FCM is well-tolerated, safe, and effective in treating iron deficiency anemia (IDA) and surpasses other interventions (Iron Sucrose Complex (ISC), Iron sucrose, and ferrous ascorbate) in elevating hemoglobin levels and replenishing iron stores.

Syst Rev 2024; 13:9. [PMID: 38169415 PMCID: PMC10759729 DOI: 10.1186/s13643-023-02400-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 11/22/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Intravenous iron (IV-iron) is used as an alternative to, or alongside, red blood cell transfusion (RBC-T) to treat more severe postpartum anemia (PPA), although optimal treatment options remain unclear. No previous systematic reviews have examined IV-iron and RBC-T, including patient-reported outcomes and hematological responses. METHODS A systematic review and meta-analysis of randomized trials comparing IV-iron and RBC-T with each other, oral iron, no treatment, and placebo for the treatment of PPA. Key inclusion criteria were PPA (hemoglobin < 12 g/dL) and IV-iron or RBC-T as interventions. Key exclusion criteria were antenatal IV-iron or RBC-T. Fatigue was the primary outcome. Secondary outcomes included hemoglobin and ferritin concentrations, and adverse events. From 27th August 2020 to 26th September 2022, databases, registries, and hand searches identified studies. A fixed-effect meta-analysis was undertaken using RevMan (5.4) software. The quality of the studies and the evidence was assessed using the Cochrane Risk of Bias table, and Grading of Recommendations, Assessment, Development, and Evaluation. This review is registered with the Prospective Register of Systematic Reviews (CRD42020201115). RESULTS Twenty studies and 4196 participants were included: 1834 assigned IV-iron, 1771 assigned oral iron, 330 assigned RBC-T, and 261 assigned non-intervention. Six studies reported the primary outcome of fatigue (1251 participants). Only studies of IV-iron vs. oral iron (15 studies) were available for meta-analysis. Of these, three reported on fatigue using different scales; two were available for meta-analysis. There was a significant reduction in fatigue with IV-iron compared to oral iron (standardized mean difference - 0.40, 95% confidence interval (CI) - 0.62, - 0.18, I2 = 0%). The direction of effect also favored IV-iron for hemoglobin (mean difference (MD) 0.54 g/dL, 95% confidence interval (CI) 0.47, 0.61, I2 = 91%), ferritin, (MD 58.07 mcg/L, 95% CI 55.74, 60.41, I2 = 99%), and total adverse events (risk-ratio 0.63, 95% CI 0.52, 0.77, I2 = 84%). The overall quality of the evidence was low-moderate. DISCUSSION For all outcomes, the evidence for RBC-T, compared to IV-iron, non-intervention, or dose effects of RBC-T is very limited. Further research is needed to determine whether RBC-T or IV-iron for the treatment of PPA is superior for fatigue and hematological outcomes.

Cost-utility analysis of ferric derisomaltose versus ferric carboxymaltose in patients with inflammatory bowel disease and iron deficiency anemia in England. J Med Econ 2024; 27:392-403. [PMID: 38391240 DOI: 10.1080/13696998.2024.2313932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/31/2024] [Indexed: 02/24/2024]
Abstract
AIMS Anemia is the most common extraintestinal complication of inflammatory bowel disease (IBD), with approximately half of cases caused by iron deficiency (ID). Intravenous iron is the preferred ID anemia (IDA) treatment where oral iron is contraindicated, ineffective or not tolerated, or where ID correction is urgent. The objective was to evaluate the cost-utility of ferric derisomaltose (FDI) versus ferric carboxymaltose (FCM) in patients with IBD and IDA in England, in whom IV iron treatment is preferred. MATERIALS AND METHODS A patient-level simulation model was developed, capturing quality of life (QoL) differences based on SF-36v2 data from the PHOSPHARE-IBD randomized controlled trial, monitoring and incidence of post-infusion hypophosphatemia, and number of iron infusions required. Analyses were conducted over a five-year time horizon from the Department of Health and Social Care (DHSC) perspective, with healthcare provider and societal perspectives adopted in separate analyses. Future costs and effects were discounted at 3.5% per annum and one-way and probabilistic sensitivity analyses were performed. RESULTS FDI increased quality-adjusted life expectancy by 0.075 QALYs versus FCM from 2.57 QALYs to 2.65 QALYs per patient. Patients receiving FDI required 1.63 fewer iron infusions over the five-year time horizon, driving infusion-related cost savings of GBP 496 per patient (GBP 2,188 versus GBP 1,692) from the DHSC perspective. Costs of monitoring and treating hypophosphatemia after FCM were GBP 226, yielding total savings of GBP 722 per patient (GBP 2,414 versus GBP 1,692) over the five-year time horizon. FDI also led to reduced costs versus FCM in the societal and provider analyses and was therefore the dominant intervention across all three perspectives. LIMITATIONS The analysis did not capture patient adherence, hypophosphatemic osteomalacia, or fractures. CONCLUSIONS Results showed that FDI improved patient QoL and reduced direct healthcare expenditure versus FCM in patients with IBD and IDA in England.

Abstract
Background Anemia affects 40% of pregnant women globally, leading to maternal mortality, premature birth, low birth weight, and poor baby development. Iron deficiency causes over 40% of anemia cases in Africa. Oral iron supplementation is insufficient for Low-and-Middle-Income-Countries (LMICs) to meet current WHO targets. We hypothesized that a single intravenous dose of Ferric Carboxymaltose (FCM) may be more effective than oral iron treatment for anemia recovery, particularly in these settings where women present late for antenatal care. Methods This is a two-arm parallel open-label individual-randomized controlled trial in third trimester, in malaria Rapid Diagnostic Test-negative pregnant women with moderate or severe anemia - capillary hemoglobin <10 g/dL - who are randomized to receive either parenteral iron - with FCM - or standard-of-care oral iron for the remainder of pregnancy. This is the sister trial to the second-trimester REVAMP trial, funded by the Bill and Melinda Gates Foundation (trial registration ACTRN12618001268235, Gates Grant number INV-010612). In REVAMP-TT, recruitment and treatment are performed within primary health centers. The trial will recruit 590 women across Zomba district, Malawi. The primary outcome is the proportion of anemic women - venous hemoglobin <11 g/dL - at 36 weeks' gestation or delivery (whichever occurs first). Other pre-specified key secondary clinical and safety outcomes include maternal iron-status and hypophosphatemia, neonate birth weight, infant growth and infant iron and hematological parameters. Discussion This study will determine whether FCM, delivered within primary health centers, is effective, safe and feasible for treating moderate to severe anemia in third-trimester pregnant Malawian women. This intervention could have long-term benefits for maternal and child health, resulting in improved survival and child development.

Abstract
Background and Objectives: Total knee arthroplasty (TKA) involves blood loss, increasing the risk of postoperative anemia and delayed functional recovery. Intravenous (IV) iron supplementation limits postoperative anemia; however, the effectiveness of IV iron, administered one day before TKA, on postoperative anemia and functional recovery has scarcely been studied. Materials and Methods: We conducted a retrospective cohort study with propensity score matching using two consecutive groups of patients who underwent TKA using tranexamic acid: the iron group received 500 mg ferric derisomaltose intravenously one day before surgery (n = 46); the non-iron group did not (n = 46). Hemoglobin (Hb) level was determined at postoperative days (PODs) 2, 4, 6, 14, and 30. Ferritin, transferrin saturation (TSAT), and functional iron deficiency anemia (IDA) rate were measured at PODs 2, 4, 6, and 14. Length of hospital stay and transfusion rate were also evaluated. Results: The iron group had higher Hb levels at PODs 6, 14, and 30 and higher ferritin and TSAT at PODs 2, 4, 6, and 14. The functional IDA rate was significantly higher in the non-iron group at PODs 2, 4, 6, and 14. Length of hospital stay was significantly shorter in the iron group; however, the rate of transfusion did not differ between the two groups. Conclusions: IV iron administered one day before TKA was associated with postoperative anemia recovery and length of hospital stay; however, it did not lower the postoperative transfusion rate.

Abstract
CONTEXT Hypophosphatemia, osteomalacia, and fractures are complications of certain intravenous iron formulations. OBJECTIVE This study investigated risk factors for incident, severe, and persistent hypophosphatemia, and associated alterations in bone and mineral biomarkers following intravenous iron treatment. METHODS We analyzed data from the PHOSPHARE-IDA randomized clinical trials, comprising 245 patients aged 18 years or older with iron deficiency anemia at 30 outpatient clinics in the United States who received intravenous ferric carboxymaltose (FCM) or ferric derisomaltose (FDI). Outcome measures included serum phosphate, intact fibroblast growth factor-23 (iFGF23), 1,25-dihydroxyvitamin D (1,25(OH)2D), ionized calcium, parathyroid hormone (PTH), and alkaline phosphatase. RESULTS FCM was the only consistent risk factor for incident hypophosphatemia (< 2.0 mg/dL; odds ratio vs FDI: 38.37; 95% CI: 16.62, 88.56; P < 0.001). Only FCM-treated patients developed severe hypophosphatemia (< 1.0 mg/dL; 11.3%; 13/115) or persistent hypophosphatemia (< 2.0 mg/dL at study end; 40.0%; 46/115). More severe hypophosphatemia associated with significantly greater increases in iFGF23, PTH, and alkaline phosphatase, and more severe decreases in 1,25(OH)2D and ionized calcium (all P < 0.05). Patients with persistent vs resolved hypophosphatemia demonstrated significantly greater changes in iFGF23, PTH, 1,25(OH)2D, and N-terminal procollagen-1 peptide levels (all P < 0.01), but alkaline phosphatase increased similarly in both groups. CONCLUSION Treatment with FCM was the only consistent risk factor for hypophosphatemia. Patients who developed severe or persistent hypophosphatemia after FCM treatment manifested more severe derangements in bone and mineral metabolism. Changes in bone biomarkers continued beyond resolution of hypophosphatemia, suggesting ongoing effects on bone that may help explain the association of FCM with osteomalacia and fractures.

Obes Surg 2022; 32:810-818. [PMID: 35000068 PMCID: PMC8866325 DOI: 10.1007/s11695-021-05858-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 12/15/2021] [Accepted: 12/17/2021] [Indexed: 11/30/2022]
Abstract
Purpose Iron deficiency is common following bariatric surgery, and treatment with intravenous iron is often required. This post hoc analysis of data from two randomized, open-label, multicenter trials evaluated the efficacy and safety of ferric derisomaltose (FDI; formerly iron isomaltoside 1000) versus iron sucrose (IS) over 4 weeks in adults with iron deficiency anemia (IDA) resulting from prior bariatric surgery. Materials and methods Data were pooled for participants who received FDI or IS in the PROVIDE or FERWON-IDA trials for the treatment of IDA post bariatric surgery. Efficacy outcomes included changes in hemoglobin (Hb) and iron parameters; safety outcomes included the incidence of adverse drug reactions (ADRs), serious or severe hypersensitivity reactions (HSRs), and hypophosphatemia. Results The analysis included 159 patients. Mean (standard deviation) cumulative iron doses were 1199 (± 347) mg for FDI and 937 (± 209) mg for IS. Compared with IS, FDI resulted in a faster and more pronounced Hb response, and a higher proportion of responders (Hb level increase ≥ 2 g/dL from baseline) at all time points. The incidence of ADRs was similar with FDI and IS (15.1% and 18.2%, respectively), with no serious ADRs or serious or severe HSRs reported. The incidence of hypophosphatemia was low and similar in both treatment groups, with no cases of severe hypophosphatemia observed. Conclusions In patients with IDA resulting from bariatric surgery, FDI produced a faster and more pronounced Hb response than IS. Both FDI and IS were well tolerated. Graphical abstract ![]()

Abstract
OBJECTIVES Two intravenous (IV) iron formulations, ferric derisomaltose (FDI) and iron sucrose (IS), are currently available for the treatment of iron deficiency anemia (IDA) in China. Clinical studies have demonstrated that FDI has an improved efficacy and safety profile versus IS, while requiring fewer infusions to correct iron deficits. Based on these findings, the present study evaluated the costs and benefits of FDI and IS for the treatment of IDA, from a healthcare system and societal perspective in China. METHODS A patient-level model was developed to project time to hematological response and incidence of cardiovascular adverse events and hypersensitivity reactions (HSRs) associated with FDI and IS over 5 years. Costs included iron acquisition, administration, and adverse event/HSR treatment costs, based on published studies, fee schedules, and a physician survey. Health state utilities associated with adverse events, HSRs, and the number of infusions were obtained from the literature and a time trade-off survey. RESULTS From a healthcare system perspective, FDI was associated with incremental costs of RMB 1,934 (purchasing power parity USD 462) and incremental quality-adjusted life expectancy of 0.078 quality-adjusted life-years (QALYs) versus IS, yielding an incremental cost-utility ratio of RMB 24,901 (USD 5,949) in the base case scenario. From a societal perspective, FDI was associated with reduced total costs and therefore dominant versus IS. LIMITATIONS Limitations included the absence of clinical data specific to China and insufficient data to model persistence with treatment. CONCLUSIONS This was the first cost-utility analysis comparing FDI and IS for the treatment of IDA in China. Based on a patient-level model, FDI was found to improve quality of life and reduce administration and adverse events costs relative to IS. Using the 2020 Chinese gross domestic product per capita of RMB 72,447 (USD 17,307) as a cost-effectiveness threshold, FDI would be considered cost-effective in China.

Abstract
Heavy menstrual bleeding in the adolescent is a cause for concern whether occurring acutely or chronically. There are a number of important considerations during the initial presentation that will help guide the practitioner during workup, which ultimately guides management strategies. The cornerstone of management in the adolescent is that of medical therapy (hormonal and nonhormonal), with avoidance of invasive and irreversible measures, as maintenance of fertility is paramount. Ultimately, the majority of adolescents can be successfully managed in the acute setting and transitioned to maintenance therapy for long-term control of heavy menses. Here, we will review the modern approach to this condition as well as tips and tricks for the practitioner.

Abstract
Objectives: Intravenous iron is the recommended treatment for patients with iron deficiency anemia (IDA) where oral iron is ineffective or rapid iron replenishment is required. Two high-dose, rapid-administration intravenous iron formulations are currently available in the UK: iron isomaltoside 1000/ferric derisomaltose (IIM) and ferric carboxymaltose (FCM). An indirect treatment comparison (ITC) recently showed that improvement from baseline hemoglobin was significantly larger with IIM than FCM. The objective was to use the ITC findings to evaluate the cost-effectiveness of IIM versus FCM from the UK healthcare payer perspective.Methods: A patient-level simulation model was developed in R to evaluate the cost per patient experiencing hematological response with IIM versus FCM. The model generated a simulated cohort from parametric distributions of baseline hemoglobin and bodyweight. Changes in hemoglobin were modeled based on data from the ITC, covaried with baseline hemoglobin based on patient-level data from a randomized controlled trial. Posological models of the iron formulations were developed based on the summaries of product characteristics. UK-specific costs were based on healthcare resource groups.Results: The proportion of patients experiencing hematological response was 9.0% higher with IIM relative to FCM (79.0% versus 70.0%), based on modeling of clinically realistic, correlated distributions of baseline hemoglobin and change from baseline hemoglobin. The mean number of infusions needed to administer the required dose was 1.92 with FCM, versus 1.38 with IIM, resulting in costs of £637 and £457 per treated patient with FCM and IIM respectively, corresponding to respective costs of £910 and £579 per responder.Conclusions: The analysis showed that using IIM rather than FCM in patients with IDA was dominant and would reduce the number of iron infusions required to correct iron deficiency, thereby reducing the costs associated with IDA treatment and simultaneously increasing the proportion of patients with IDA experiencing a clinically meaningful hematological response.

Abstract
Introduction Intravenous (IV) iron is typically the preferred treatment for patients with iron deficiency anemia (IDA) who cannot tolerate or absorb oral iron, or who require fast replenishment of iron stores pre-operatively. Several IV iron formulations are available with different dosing characteristics affecting infusion speed and maximum dose. The aim was to develop a resource impact model to calculate the cost of establishing an IV iron clinic and model resource impact of different IV irons to inform clinicians and service providers implementing innovative pre-operative IV iron services in Ireland. Methods A resource impact tool was developed to model resource utilization and IDA treatment costs. Two fast-administration, high-dose formulations of IV iron are available in Ireland: iron isomaltoside 1000/ferric derisomaltose (IIM) and ferric carboxymaltose (FCM). The tool modeled clinic throughput based on their different dosing characteristics in a specific IDA population, capturing fixed overheads, variable costs, clinic income from private and publicly-funded patients, and savings associated with IV iron. Results Based on a 70:30 split between public and private patients in a new pre-operative service with capacity for 12 infusion slots weekly, IIM would facilitate correction of iron deficits in 474 patients annually, resulting in a net annual clinic balance of €42,736 on income of €159,887 and net costs of €117,151. FCM would facilitate treatment of 353 patients, resulting in a net annual clinic balance of €36,327 on income of €116,050 and costs of €79,722, a difference of €6408 and 121 patients treated in favor of using IIM over FCM. Conclusion Based on this provider-perspective analysis, IIM would maximize clinic throughput relative to other IV iron formulations, allowing clinicians in Ireland to optimize their current service provision and expenditure, and model the impact of introducing IV iron clinics for pre-operative patients with IDA.

Abstract
There is an increasing awareness of the prevalence of iron deficiency in patients with heart failure (HF), and its contributory role in the morbidity and mortality of HF. Iron is a trace element necessary for cells due to its capacity to transport oxygen and electrons. The prevalence of iron deficiency increases with the severity of HF. For a long time the influence of iron deficiency was underestimated, especially in terms of worsening of cardiovascular diseases and developing anaemia. In recent years, studies with intravenous iron agents in patients with iron deficiency and HF showed new insights into the improvement of iron therapy. Additionally, experimental studies supporting the understanding of iron metabolism and the resulting pathophysiological pathways of iron have been carried out. The aim of this mini review is to highlight why iron deficiency is recognised as an important comorbidity in HF.
