Ferric maltol is an orally active complex of a single ferric ion (Fe3+). Ferric maltol has tha potential for iron deficiency anemia treatment in inflammatory bowel disease[1].
The administration of Ferric maltol can increase transferrin saturation and levels of serum iron, serum ferritin, reticulocyte hemoglobin, and blood hemoglobin[1].
Animal studies show that iron that is not absorbed from Ferric maltol can remain in its chelated form at least throughout the small intestine, minimizing the risk of intestinal mucosal damage from free iron and potentially reducing local toxicity[1].

Ferric maltol: A New Oral Iron Formulation for the Treatment of Iron Deficiency in Adults
Ann Pharmacother 2021 Feb;55(2):222-229.PMID:32633548DOI:10.1177/1060028020941014.
Objective: To review the pharmacology, efficacy, and safety of Ferric maltol (FM), an oral iron formulation, for iron deficiency anemia (IDA). Data sources: A MEDLINE/PubMed and EMBASE (January 1, 1985, to June 19, 2020) literature search was performed using the terms Ferric maltol, accrufer, feraccru, iron maltol, ferric trimaltol, iron deficiency, iron deficiency anemia, inflammatory bowel disease, and chronic kidney disease. Additional data sources included prescribing information, abstracts, and the National Institutes of Health Clinical Trials Registry. Study selection/data extraction: English language literature evaluating FM pharmacology, pharmacokinetics, efficacy, or safety in the treatment of IDA were reviewed. Data synthesis: FM is a ferric, non-salt-based oral iron formulation demonstrating improved tolerance in patients with previous intolerance to other iron formulations. Phase 3 trials demonstrated significant improvements in anemia and serum iron parameters in patients with inflammatory bowel disease (IBD) and chronic kidney disease (CKD). Common adverse effects were gastrointestinal intolerance. Relevance to patient care and clinical practice: FM is an effective and well-tolerated alternative to oral iron salts for patients with IBD or CKD and IDA. Emerging data suggest that FM is noninferior to intravenous (IV) ferric carboxymaltose in patients with IBD and IDA. Prior to selecting FM over IV iron products, consideration should be given to time to normalization of Hb, ease of administration, cost, and tolerability. Conclusion: FM is a relatively safe, effective oral iron therapy that may be better tolerated than other oral iron formulations. FM may be an effective alternative to IV iron in patients with IBD.
Long-Term Effectiveness of Oral Ferric maltol vs Intravenous Ferric Carboxymaltose for the Treatment of Iron-Deficiency Anemia in Patients With Inflammatory Bowel Disease: A Randomized Controlled Noninferiority Trial
Inflamm Bowel Dis 2022 Mar 2;28(3):373-384.PMID:33988236DOI:10.1093/ibd/izab073.
Background: Iron-deficiency anemia is common in inflammatory bowel disease, requiring oral or intravenous iron replacement therapy. Treatment with standard oral irons is limited by poor absorption and gastrointestinal toxicity. Ferric maltol is an oral iron designed for improved absorption and tolerability. Methods: In this open-label, phase 3b trial (EudraCT 2015-002496-26 and NCT02680756), adults with nonseverely active inflammatory bowel disease and iron-deficiency anemia (hemoglobin, 8.0-11.0/12.0 g/dL [women/men]; ferritin, <30 ng/mL/<100 ng/mL with transferrin saturation <20%) were randomized to oral Ferric maltol 30 mg twice daily or intravenous ferric carboxymaltose given according to each center's standard practice. The primary endpoint was a hemoglobin responder rate (≥2 g/dL increase or normalization) at week 12, with a 20% noninferiority limit in the intent-to-treat and per-protocol populations. Results: For the intent-to-treat (Ferric maltol, n = 125/ferric carboxymaltose, n = 125) and per-protocol (n = 78/88) analyses, week 12 responder rates were 67% and 68%, respectively, for Ferric maltol vs 84% and 85%, respectively, for ferric carboxymaltose. As the confidence intervals crossed the noninferiority margin, the primary endpoint was not met. Mean hemoglobin increases at weeks 12, 24, and 52 were 2.5 vs 3.0 g/dL, 2.9 vs 2.8 g/dL, and 2.7 vs 2.8 g/dL with Ferric maltol vs ferric carboxymaltose. Treatment-emergent adverse events occurred in 59% and 36% of patients, respectively, and resulted in treatment discontinuation in 10% and 3% of patients, respectively. Conclusions: Ferric maltol achieved clinically relevant increases in hemoglobin but did not show noninferiority vs ferric carboxymaltose at week 12. Both treatments had comparable long-term effectiveness for hemoglobin and ferritin over 52 weeks and were well tolerated.
Recent and Emerging Therapies for Iron Deficiency in Anemia of CKD: A Review
Am J Kidney Dis 2022 Jun;79(6):868-876.PMID:34758368DOI:10.1053/j.ajkd.2021.09.017.
Iron deficiency commonly contributes to the anemia affecting individuals with chronic kidney disease. This review describes diagnostic criteria for iron deficiency in chronic kidney disease, as well as mechanisms of functional and absolute iron deficiency and general treatment principles as delineated in the KDIGO (Kidney Disease: Improving Global Outcomes) guideline. Repletion of absolute iron deficits has progressed over time with the addition of better tolerated, more effective oral agents, including ferric citrate, Ferric maltol, and sucrosomial iron. This article examines the structural characteristics and trial data enabling regulatory approval of these novel oral agents. Newer intravenous iron therapies, including ferric carboxymaltose and ferric derisomaltose, allow for fewer infusions and decreased risk of serious hypersensitivity reactions. Concerns about adverse effects such as cardiovascular events and infections are discussed. The potential risk of 6H syndrome (high FGF-23, hypophosphatemia, hyperphosphaturia, hypovitaminosis D, hypocalcemia, and secondary hyperparathyroidism) due to these intravenous agents is emphasized. The proposed pathophysiology of 6H syndrome and hypophosphatemia is described. Ferric pyrophosphate citrate enables administration of iron for repletion through dialysate. Relative merits, costs, and risks of various iron agents such as hypersensitivity and 6H syndrome/hypophosphatemia are summarized.
Iron Replacement Therapy with Oral Ferric maltol: Review of the Evidence and Expert Opinion
J Clin Med 2021 Sep 28;10(19):4448.PMID:34640466DOI:10.3390/jcm10194448.
Iron deficiency is the most common cause of anemia globally and is frequently reported in patients with underlying inflammatory conditions, such as inflammatory bowel disease (IBD) and chronic kidney disease (CKD). Ferric maltol is a new oral iron replacement therapy designed to optimize iron absorption while reducing the gastrointestinal adverse events associated with unabsorbed free iron. Ferric maltol has been studied in clinical trials involving almost 750 adults and adolescents with iron-deficiency anemia associated with IBD, CKD, and other underlying conditions, and it has been widely used in clinical practice. It is approved for the treatment of adults with iron deficiency with or without anemia, independent of the underlying condition, and is commercially available in Europe and the United States. We review the published evidence for Ferric maltol, which demonstrates consistent and clinically meaningful improvements in hemoglobin and measures of iron availability (ferritin and transferrin saturation) and shows that it is well-tolerated over long-term treatment for up to 64 weeks-an important consideration in patients with chronic underlying conditions such as IBD and CKD. We believe that Ferric maltol is an effective, convenient, and well-tolerated treatment option for iron deficiency and iron-deficiency anemia, especially when long-term management of chronic iron deficiency is required.

Ferric maltol (ST10): a novel oral iron supplement for the treatment of iron deficiency anemia in inflammatory bowel disease
Expert Opin Pharmacother 2015;16(18):2859-67.PMID:26595432DOI:10.1517/14656566.2015.1096929.
Introduction: Iron deficiency anemia affects up to three quarters of patients with inflammatory bowel disease (IBD). It can significantly impact the quality of life and the ability to work by impairing physical, emotional, and cognitive functioning. The etiology of iron deficiency anemia is multifactorial and oral or intravenous iron replacement is necessary. However, oral iron supplements are often discontinued prematurely due to poor tolerability or insufficient efficacy. Moreover, intravenous supplementation is inconvenient, associated with potentially serious safety risks, and a burden on healthcare resources. Areas covered: Ferric maltol is a novel ferric iron compound with potential use as an oral therapy for iron deficiency anemia. This overview explains how the molecule's design impacts clinical outcomes and summarizes available clinical data (ranging from early comparisons with ferrous sulfate to randomized, placebo-controlled, Phase III data in patients with IBD known to be intolerant of oral ferrous products). Expert opinion: Ferric maltol offers the ability to treat iron deficiency anemia in mild-to-moderate IBD without resorting to intravenous therapy, even in those who are intolerant of oral ferrous products. This clinical benefit has the potential to change treatment pathways and increase choice, not only in IBD but also perhaps in many areas beyond gastroenterology.
