What is Accrufer?

From the FDA label:ACCRUFER (ferric maltol) capsules, an iron replacement product for oral administration, contain 30 mg iron and 201.5 mg maltol. Ferric maltol contains iron in a stable ferric state as a complex with a trimaltol ligand. Ferric maltol is 3-hydroxy-2-methyl-4H-pyrane-4-one iron (III) complex (3:1) and has the molecular formula (C 6 H 5 O 3 ) 3 Fe and a molecular mass of 431.2. Each red capsule, printed with “30”, contains colloidal anhydrous silica, crospovidone (Type A), lactose monohydrate, magnesium stearate and sodium lauryl sulfate as inactive ingredients. In addition, the capsule shell contains FD&C Blue No. 1, FD&C Red No. 40, FD&C Yellow No.6, hypromellose and titanium dioxide. The ink used for printing the marking contains Shellac, ammonium hydroxide, ethanol, iron oxide black and propylene glycol. Image 1

How to use

30 mg orally twice daily on an empty stomach 1 hour before or 2 hours after meals ( 2.1 ) Swallow capsules whole. Do not open, break, or chew capsules. ( 2.1 ) Continue as long as necessary to replenish body iron stores ( 2.1 ) 2.1 Recommended Dosage Adults and Children Aged 10 Years and Above ​ The recommended dosage of ACCRUFER is 30 mg orally twice daily, on an empty stomach 1 hour before or 2 hours after meals. Swallow capsules whole. Do not open, break, or chew capsules. Treatment duration will depend on the severity of iron deficiency but generally at least 12 weeks of treatment is required. The treatment should be continued as long as necessary until ferritin levels are within the normal range.

Side effects

The following clinically significant adverse reactions are described elsewhere in the labeling: Increased Risk of Inflammatory Bowel Disease Flare [see Warnings and Precautions ( 5.1 )] Iron Overload [see Warnings and Precautions ( 5.2 )] Most common adverse reactions (incidence > 1%) are flatulence, diarrhea, constipation, feces discolored, abdominal pain, nausea, vomiting and abdominal discomfort/distension. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Shield Therapeutics Inc at 1-888-963-6267 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to ACCRUFER in 175 adult patients in the placebo-controlled phase of three randomized studies conducted in patients with anemia and quiescent inflammatory bowel disease (IBD) (Studies AEGIS 1 & 2) or non-dialysis dependent chronic kidney disease (CKD) (AEGIS 3). The pooled patient population had a mean age of 58 years, 67.4% were female (n=118), and 81.7% (n=143) were Caucasian. Table 1 presents all adverse reactions occurring in the placebo-controlled period of the pooled randomized studies…

Warnings

Important safety information

IBD Flare: Avoid use in patients with IBD flare ( 5.1 ) Iron Overload: Do not administer to patients with iron overload or those receiving intravenous iron. ( 5.2 ) Risk of Overdosage in Children Due to Accidental Ingestion: Keep out of reach of children. ( 5.3 ) 5.1 Increased Risk of Inflammatory Bowel Disease (IBD) Flare Avoid use of ACCRUFER in patients with an active inflammatory bowel disease (IBD) flare, as there is potential risk of increased inflammation in the gastrointestinal tract. 5.2 Iron Overload Excessive therapy with iron products can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Do not administer ACCRUFER to patients with evidence of iron overload or patients receiving intravenous iron [see Contraindications ( 4 )] . Assess iron parameters prior to initiating ACCRUFER and monitor iron parameters while on therapy [see Overdosage ( 10 ) and Clinical Pharmacology ( 12.2 )] . 5.3 Risk of Overdosage in Children Due to Accidental Ingestion Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.

Who should not take Accrufer

ACCRUFER is contraindicated in patients with a history of: Hypersensitivity to the active substance or to any of the excipients [see Description ( 11 )] . Reactions could include shock, clinically significant hypotension, loss of consciousness, and/or collapse. Hemochromatosis and other iron overload syndromes [see Warnings and Precautions ( 5.1 )] . Use may result in iron overdose [see Overdosage ( 10 )]. Receiving repeated blood transfusions. Use may result in iron overload [see Warnings and Precautions ( 5.2 ) and Overdosage ( 10 )]. Hypersensitivity to the active substance or any excipient ( 4 ) Hemochromatosis and other iron overload syndromes ( 4 ) Patients receiving repeated blood transfusions ( 4 )

Overdose — what happens if you take too much

No data are available regarding overdose of ACCRUFER in patients. Acute iron ingestion of 20 mg/kg elemental iron is potentially toxic and 200- 250 mg/kg is potentially fatal. Early signs and symptoms of iron overdose may include nausea, vomiting, abdominal pain and diarrhea. In more serious cases there may be evidence of hypoperfusion, metabolic acidosis and systemic toxicity. Dosages of ACCRUFER in excess of iron needs may lead to accumulation of iron in storage sites leading to hemosiderosis. Periodic monitoring of iron parameters such as serum ferritin and transferrin saturation may assist in recognizing iron accumulation. Do not administer ACCRUFER to patients with iron overload [ see Contraindications ( 4 ) ] . Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

U.S. Poison Control: call or text 1-800-222-1222 (free, 24/7). In an emergency call 911. From the FDA label; not medical advice.

Interactions

Dimercaprol : Avoid concomitant use. ( 7.2 ) Oral Medications : Separate administration of ACCRUFER from certain oral medications. Monitor clinical responses as appropriate. ( 7.1 , 7.2 ) 7.1 Effect of Other Drugs on ACCRUFER Oral Medications There are no empirical data on avoiding drug interactions between ACCRUFER and concomitant oral medications. Concomitant use of some drugs may reduce the bioavailability of iron after administration of ACCRUFER. Separate the administration of ACCRUFER from these drugs. The duration of separation may depend on the absorption characteristics of the medication concomitantly administered, such as time to peak concentration or whether the drug is an immediate or extended release product. Monitor clinical response to ACCRUFER. 7.2 Effect of ACCRUFER on Other Drugs Dimercaprol Concomitant use of iron products with dimercaprol may increase the risk of nephrotoxicity. Avoid concomitant use of ACCRUFER with dimercaprol. Oral Medications Concomitant use of ACCRUFER may decrease the bioavailability of some drugs, including mycophenolate, ethinyl estradiol, ciprofloxacin and doxycycline [see Clinical Pharmacology ( 12.3 )] . For oral drugs where reductions in bioavailability may cause clinically significant effects on its safety or efficacy, separate the administration of ACCRUFER by at least 4 hours. Monitor clinical responses to concomitant drugs as appropriate.
