Abstract
Ferumoxytol, approved by the U.S. Food and Drug Administration in 2009, is one of the intravenous iron oxide nanoparticles authorized for the treatment of iron deficiency in chronic kidney disease and end-stage renal disease. With its exceptional magnetic properties, catalytic activity, and immune activity, as well as good biocompatibility and safety, ferumoxytol has gained significant recognition in various biomedical diagnoses and treatments. Unlike most existing reviews on this topic, this review primarily focuses on the recent clinical and preclinical advances of ferumoxytol in disease treatment, spanning anemia, cancer, infectious inflammatory diseases, regenerative medicine application, magnetic stimulation for neural modulation, etc. Additionally, the newly discovered mechanisms associated with the biological effects of ferumoxytol are discussed, including its magnetic, catalytic, and immunomodulatory properties. Finally, the summary and future prospects concerning the treatment and application of ferumoxytol-based nanotherapeutics are presented.

Abstract
Introduction The efficacy of iron isomaltoside ferumoxytol versus iron sucrose to treat iron deficiency anemia remains controversial. We conduct this meta-analysis to explore the influence of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia. Methods We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2021 for randomized controlled trials (RCTs) assessing the effect of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia. Meta-analysis was performed using the random-effect model. Results Four RCTs involving 3892 patients were included in the meta-analysis. Overall, compared with iron sucrose for iron deficiency anemia, iron isomaltoside showed similar change of Hb (SMD=0.14; 95% CI=-0.07 to 0.35; P=0.18), Hb responder (SMD=1.41; 95% CI=0.71 to 2.81; P=0.33), serum ferritin (SMD=15.13; 95% CI=-23.45 to 53.71; P=0.44), and transferrin saturation (SMD=1.20; 95% CI=-1.08 to 3.47; P=0.30). However, iron isomaltoside further improved serum-ferritin at week 2 than iron sucrose (SMD=204.79; 95% CI=38.23 to 371.35; P=0.02). Conclusions Iron isomaltoside ferumoxytol showed comparable efficacy to iron sucrose for the treatment of iron deficiency anemia.

Abstract
Background Iron deficiency anemia (IDA) is a common cause of fatigue and impaired quality of life. The present study aimed to evaluate the impact of intravenous iron supplementation with ferric carboxymaltose (FCM) on fatigue, physical function, and general health among patients with IDA attending routine clinical care. Methods This was a prospective, single arm, observational study of adult patients prescribed with intravenous FCM for the treatment of IDA during routine clinical care. We used Patient-Reported Outcomes Measurement Information System (PROMIS) instruments to evaluate fatigue (PROMIS Short Form v1.0 13a [FACIT-Fatigue]), general health status (PROMIS Scale v1.2), and physical function (PROMIS Short Form v2.0 4a) before and at 3 and 6 months after FCM treatment. Results A total of 152 patients were enrolled. Mean age was 47.4 ± 16.0 years and 82.2% were female. Mean serum hemoglobin was 10.2 ± 1.4 g/dL at baseline. All patients were treated with at least one FCM dose at baseline, with 77.6% receiving a two-dose treatment course. The mean baseline FACIT-Fatigue score was 61.0 ± 9.0, improving significantly to 50.2 ± 9.5 at 3 months after FCM treatment. A minimum 5-point improvement, pre-defined as clinically meaningful, was seen in the FACIT-Fatigue, PROMIS Global Physical Health, Global Mental Health and PROMIS Physical Function scores for 72.7%, 52.8%, 41.7% and 39.8% of patients at 3 months (p < 0.0001 for each change from baseline), with statistically significant improvement continuing at 6 months. Mean serum hemoglobin was significantly increased at both 3 and 6 months (12.8 g/dL [N = 44] and 12.4 g/dL [N = 54], respectively). Conclusion IDA patients attending routine clinical practice reported substantial levels of fatigue and impairments in physical function and global health prior to intravenous iron treatment. Patients experienced significant improvements in fatigue symptoms, physical function, and global health at 3 months after treatment with FCM, which were sustained at 6 months.

Abstract
INTRODUCTION Acute gastrointestinal bleeding (GIB) is a life-threatening emergency with a critical economic burden. As a result of bleeding, anaemia often requires intravenous or oral iron supplementation. Elderly patients are even more prone to untoward outcomes after hospital discharge if iron supplementation is inefficient. There is a gap in current guidelines on which supplementation route clinicians should choose. We aim to investigate the effect of one dose of intravenous iron therapy versus 3-month oral iron administration on anaemia in an elderly population. METHODS AND ANALYSIS The FIERCE study is an open-label, randomised controlled, two-armed trial. At least 48 hours after the acute non-variceal GIB treatment, patients will be recruited in participating centres. A random sequence generator will allocate the participants to group A (intravenous ferric carboxymaltose, 1000 mg) or group B (oral ferrous sulfate (FS), ca. 200 mg every day) with an allocation ratio of 1:1 on the day of the planned discharge from the hospital. Randomisation will be stratified for participating centres and the need for transfusion within the same hospitalisation before recruitment to the trial. Quality of life assessment, functional measurement and laboratory tests will be performed at baseline, 1 and 3 months±7 days after enrolment to the trial. The primary endpoint is a composite endpoint, including all-cause mortality, anaemia-associated unplanned emergency visit and anaemia-associated unplanned hospital admission within 3 months of enrolment in the trial. ETHICS AND DISSEMINATION The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (46395-5/2021/EÜIG). We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION The trial has been registered at ClinicalTrials.gov (NCT05060731).

Abstract
Iron deficiency anemia affects approximately 45% of patients with inflammatory bowel disease (IBD), negatively impacts the quality of life in this patient population, and significantly burdens our healthcare system. The pathogenesis of iron deficiency in IBD patients is multifactorial, including intestinal bleeding, malabsorption, and inadequate oral intake. Regular screening and diagnosis in these patients are imperative, and often patients have mixed iron deficiency anemia and anemia of chronic disease, especially in those with active inflammation. Iron may be replenished either orally or intravenously. While oral iron is safe, affordable, and easy to administer, patients often suffer from intolerable gastrointestinal side effects, and particularly in IBD patients, oral iron may increase inflammation and contribute to flares. Therefore, although it is substantially underused, intravenous (IV) iron is considered first-line treatment for patients with active disease, severe anemia, oral iron intolerance, and erythropoietin requirements. Several IV iron formulations are available, and iron sucrose and ferric carboxymaltose are the most frequently used and well studied in patients with IBD. However, iron isomaltoside could potentially become a popular choice among providers given its safety, efficacy, and convenience. Overall, screening, diagnosis, and treatment of iron deficiency anemia are important in patients with IBD. Individual patient characteristics, risks, and benefits, and advantages and disadvantages, should be considered when determining the best route and formulation for iron repletion.

Abstract
AIMS Novel oral iron supplements may be associated with a reduced incidence of adverse drug reactions compared to standard treatments of iron deficiency anaemia. The aim was to establish their value-based price under conditions of uncertainty surrounding their tolerability. METHODS A discrete-time Markov model was developed to assess the value-based price of oral iron preparations based on their incremental cost per quality-adjusted life year (QALY) gained from the perspective of the NHS in the UK. Primary and secondary care resource use and health state occupancy probabilities were estimated from routine electronic health records; and unit costs and health state utilities were derived from published sources. Patients were pre-menopausal women with iron deficiency anaemia who were prescribed oral iron supplementation between 2000 and 2014. RESULTS The model reflecting current use of iron salts yielded a mean total cost to the NHS of £779, and 0.84 QALYs over 12 months. If a new iron preparation were to reduce the risk of adverse drug reactions by 30-40%, then its value-based price, based on a threshold of £20 000 per QALY, would be in the region of £10-£13 per month, or about 7-9 times the average price of basic iron salts. CONCLUSIONS There are no adequate, direct comparisons of new oral iron supplements to ferrous iron salts, and therefore other approaches are needed to assess their value. Our modelling shows that they are potentially cost-effective at prices that are an order of magnitude higher than existing iron salts.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is an umbrella term used to describe a group of chronic, progressive inflammatory disorders of the digestive tract. Crohn's disease and ulcerative colitis are the two main types. Fatigue is a common, debilitating and burdensome symptom experienced by individuals with IBD. The subjective, complex nature of fatigue can often hamper its management. The efficacy and safety of pharmacological or non-pharmacological treatments for fatigue in IBD is not yet established through systematic review of studies. OBJECTIVES To assess the efficacy and safety of pharmacological and non-pharmacological interventions for managing fatigue in IBD compared to no treatment, placebo or active comparator. SEARCH METHODS A systematic search of the databases Embase, MEDLINE, Cochrane Library, CINAHL, PsycINFO was undertaken from inception to July 2018. A top-up search was run in October 2019. We also searched the Cochrane IBD Group Specialized Register, the Cochrane Central Register of Controlled Trials, ongoing trials and research registers, conference abstracts and reference lists for potentially eligible studies. SELECTION CRITERIA Randomised controlled trials of pharmacological and non-pharmacological interventions in children or adults with IBD, where fatigue was assessed as a primary or secondary outcome using a generic or disease-specific fatigue measure, a subscale of a larger quality of life scale or as a single-item measure, were included. DATA COLLECTION AND ANALYSIS Two authors independently screened search results and four authors extracted and assessed bias independently using the Cochrane 'Risk of bias' tool. The primary outcome was fatigue and the secondary outcomes included quality of life, adverse events (AEs), serious AEs and withdrawal due to AEs. Standard methodological procedures were used. MAIN RESULTS We included 14 studies (3741 participants): nine trials of pharmacological interventions and five trials of non-pharmacological interventions. Thirty ongoing studies were identified, and five studies are awaiting classification. Data on fatigue were available from nine trials (1344 participants). In only four trials was managing fatigue the primary intention of the intervention (electroacupuncture, physical activity advice, cognitive behavioural therapy and solution-focused therapy). Electroacupuncture Fatigue was measured with Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) (scores range from 0 to 52). The FACIT-F score at week eight was 8.00 points higher (better) in participants receiving electroacupuncture compared with no treatment (mean difference (MD) 8.00, 95% CI 6.45 to 9.55; 1 RCT; 27 participants; low-certainty evidence). Results at week 16 could not be calculated. FACIT-F scores were also higher with electroacupuncture compared to sham electroacupuncture at week eight (MD 5.10, 95% CI 3.49 to 6.71; 1 RCT; 30 participants; low-certainty evidence) but not at week 16 (MD 2.60, 95% CI 0.74 to 4.46; 1 RCT; 30 participants; low-certainty evidence). No adverse events were reported, except for one adverse event in the sham electroacupuncture group. Cognitive behavioural therapy (CBT) and solution-focused therapy Compared with a fatigue information leaflet, the effects of CBT on fatigue are very uncertain (Inflammatory Bowel Disease-Fatigue (IBD-F) section I: MD -2.16, 95% CI -6.13 to 1.81; IBD-F section II: MD -21.62, 95% CI -45.02 to 1.78; 1 RCT, 18 participants, very low-certainty evidence). The efficacy of solution-focused therapy on fatigue is also very uncertain, because standard summary data were not reported (1 RCT, 98 participants). Physical activity advice One 2 x 2 factorial trial (45 participants) found physical activity advice may reduce fatigue but the evidence is very uncertain. At week 12, compared to a control group receiving no physical activity advice plus omega 3 capsules, FACIT-F scores were higher (better) in the physical activity advice plus omega 3 group (FACIT-F MD 6.40, 95% CI -1.80 to 14.60, very low-certainty evidence) and the physical activity advice plus placebo group (FACIT-F MD 9.00, 95% CI 1.64 to 16.36, very low-certainty evidence). Adverse events were predominantly gastrointestinal and similar across physical activity groups, although more adverse events were reported in the no physical activity advice plus omega 3 group. Pharmacological interventions Compared with placebo, adalimumab 40 mg, administered every other week ('eow') (only for those known to respond to adalimumab induction therapy), may reduce fatigue in patients with moderately-to-severely active Crohn's disease, but the evidence is very uncertain (FACIT-F MD 4.30, 95% CI 1.75 to 6.85; very low-certainty evidence). The adalimumab 40 mg eow group was less likely to experience serious adverse events (OR 0.56, 95% CI 0.33 to 0.96; 521 participants; moderate-certainty evidence) and withdrawal due to adverse events (OR 0.48, 95%CI 0.26 to 0.87; 521 participants; moderate-certainty evidence). Ferric maltol may result in a slight increase in fatigue, with better SF-36 vitality scores reported in the placebo group compared to the treatment group following 12 weeks of treatment (MD -9.31, 95% CI -17.15 to -1.47; 118 participants; low-certainty evidence). There may be little or no difference in adverse events (OR 0.55, 95% CI 0.26 to 1.18; 120 participants; low-certainty evidence) AUTHORS' CONCLUSIONS: The effects of interventions for the management of fatigue in IBD are uncertain. No firm conclusions regarding the efficacy and safety of interventions can be drawn. Further high-quality studies, with a larger number of participants, are required to assess the potential benefits and harms of therapies. Future studies should assess interventions specifically designed for fatigue management, targeted at selected IBD populations, and measure fatigue as the primary outcome.

Introduction Hypersensitivity reactions (HSRs) are among the known adverse events of intravenous (i.v.) iron products. Of these, particularly severe HSRs such as anaphylaxis are of great clinical concern due to their life-threatening potential. Methods This was a retrospective pharmacoepidemiological study with a case-population design evaluating the number of reported severe HSRs following administration of the two i.v. iron products—ferric carboxymaltose and iron (III) isomaltoside 1000—in relation to exposure in European countries from January 2014 to December 2017. Exposure to both products was estimated using IQVIA MIDAS sales data in European countries. Information on spontaneously reported severe HSRs was obtained from and analysed separately for the two established safety surveillance databases EudraVigilance and VigiBase™ using the MedDRA® Preferred Terms anaphylactic reaction, anaphylactic shock, anaphylactoid reaction and anaphylactoid shock associated with administration of either product. Results Between 2014 and 2017, the reporting rate of severe HSRs per 100,000 defined daily doses (100 mg dose equivalents of iron) varied from 0.3 to 0.5 for ferric carboxymaltose and from 2.4 to 5.0 for iron (III) isomaltoside 1000. The reporting rate ratio for iron (III) isomaltoside 1000 versus ferric carboxymaltose was between 5.6 (95% CI 3.5–9.0) and 16.2 (95% CI 9.4–27.8). Conclusions Findings suggest that iron (III) isomaltoside 1000 is associated with a higher reporting rate of severe HSRs related to estimated exposure than ferric carboxymaltose in European countries. Future research investigating the occurrence of severe HSRs associated with i.v. ferric carboxymaltose and iron (III) isomaltoside 1000 is needed to broaden the evidence for benefit-risk assessment.

Abstract
INTRODUCTION This systematic review and meta-analysis aims to explore the influence of ferumoxytol versus placebo on iron deficiency anemia. METHODS We search for randomized controlled trials (RCTs) assessing the effect of ferumoxytol on iron deficiency anemia on PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases. This meta-analysis is performed using the random-effects model. RESULTS Four RCTs are included in the meta-analysis. Compared with the control group for iron deficiency anemia, intravenous ferumoxytol can significantly improve the proportion of patients with a ≥20 g/L hemoglobin (Hb) increase (RR = 18.43; 95% CI = 7.29-46.57; p < 0.00001), the proportion of patients with an Hb level ≥120 g/L (RR = 18.55; 95% CI = 8.66-39.72; p < 0.00001), transferrin saturation (mean difference = 11.08; 95% CI = 9.86-12.31; p < 0.00001) and FACIT-fatigue score (mean difference = 4.60; 95% CI = 3.21-6.00; p < 0.00001), but has no remarkable influence on adverse events (RR = 1.33; 95% CI = 0.84-2.10; p = 0.22), serious adverse events (RR = 1.22; 95% CI = 0.74-2.02; p = 0.44), and death (RR = 0.32; 95% CI = 0.05-1.95; p = 0.22). CONCLUSIONS Intravenous ferumoxytol can provide the important benefits for iron deficiency anemia.

Abstract
Anaemia is the most frequent, though often neglected, comorbidity of inflammatory bowel disease (IBD). Here we want to briefly present (1) the burden of anaemia in IBD, (2) its pathophysiology, which mostly arises from bleeding-associated iron deficiency, followed by (3) diagnostic evaluation of anaemia, (4) a balanced overview of the different modes of iron replacement therapy, (5) evidence for their therapeutic efficacy and subsequently, (6) an updated recommendation for the practical management of anaemia in IBD. Following the introduction of various intravenous iron preparations over the last decade, questions persist about when to use these preparations as opposed to traditional and other novel oral iron therapeutic agents. At present, oral iron therapy is generally preferred for patients with quiescent IBD and mild iron-deficiency anaemia. However, in patients with flaring IBD that hampers intestinal iron absorption and in those with inadequate responses to or side effects with oral preparations, intravenous iron supplementation is the therapy of choice, although information on the efficacy of intravenous iron in patients with active IBD and anaemia is scare. Importantly, anaemia in IBD is often multifactorial and a careful diagnostic workup is mandatory for optimized treatment. Nevertheless, limited information is available on optimal therapeutic start and end points for treatment of anaemia. Of note, neither oral nor intravenous therapies seem to exacerbate the clinical course of IBD. However, additional prospective studies are still warranted to determine the optimal therapy in complex conditions such as IBD.

Comparative safety of intravenous Ferumoxytol versus Ferric Carboxymaltose for the Treatment of Iron Deficiency Anemia: rationale and study design of a randomized double-blind study with a focus on acute hypersensitivity reactions.

Abstract
Background Intravenous (IV) iron is often used to treat iron deficiency anemia in patients who are unable to tolerate or are inadequately managed with oral iron. However, IV iron treatment has been associated with acute hypersensitivity reactions. The comparative risk of adverse events (AEs) with IV iron preparations has been assessed by a few randomized controlled trials, which are most often limited by small patient numbers, which lack statistical power to identify differences in low-frequency AE such as hypersensitivity reactions. Materials and methods Ferumoxytol versus Ferric Carboxymaltose for the Treatment of Iron Deficiency Anemia (FIRM) is a randomized, double-blind, international, multicenter, Phase III study designed to compare the safety of ferumoxytol and ferric carboxymaltose (FCM). The study includes adults with hemoglobin <12.0 g/dL (females) or <14.0 g/dL (males), transferrin saturation ≤20% or ferritin ≤100 ng/mL within 60 days of dosing, and a history of unsatisfactory or nontolerated oral iron therapy or in whom oral iron therapy is inappropriate. Patients are randomized (1:1) to ferumoxytol 510 mg or FCM 750 mg, each given intravenously on days 1 and 8. Primary end points are the incidence of moderate-to-severe hypersensitivity reactions, including anaphylaxis, and moderate-to-severe hypotension. All potential hypersensitivity and hypotensive reactions will be adjudicated by a blinded, independent Clinical Events Committee. A secondary safety end point is the composite frequency of moderate-to-severe hypersensitivity reactions, including anaphylaxis, serious cardiovascular events, and death. Secondary efficacy end points include mean change in hemoglobin and mean change in hemoglobin per milligram of iron administered from baseline to week 5. Urinary excretion of phosphorus and the occurrence of hypophosphatemia after IV iron administration will be examined as well as the mechanisms of such hypophosphatemia in a substudy. Conclusion FIRM will provide data on the comparative safety of ferumoxytol and FCM, two IV iron preparations with similar dosing schedules, focusing on moderate-to-severe hypersensitivity reactions, including anaphylaxis, and moderate-to-severe hypotension. The study plans to enroll 2000 patients and is expected to complete in 2017.
