FERRIC DERISOMALTOSE: 1,023 Adverse Event Reports & Safety Profile

Monoferric is an iron replacement product containing ferric derisomaltose for intravenous infusion. Ferric derisomaltose is an iron carbohydrate complex with a matrix structure composed of interchanging layers of ferric hydroxide and the carbohydrate derisomaltose. Derisomaltose consists of linear, hydrogenated isomaltooligosaccharides with an average molecular weight of 1000 Da and a narrow molecular weight distribution that is almost devoid of mono- and disaccharides. Ferric derisomaltose has an average molecular weight of 155,000 Da and has the following empirical formula: {FeO (1-3X) (OH) (1+3X) (C 6 H 5 O 7 3- ) X }, (H 2 0) T , - (C 6 H 10 O 6 ) R (-C 6 H 10 O 5 -) Z (C 6 H 13 O 5 ) R , (NaCl) Y X = 0.0311; T = 0.25; R = 0.14; Z = 0.49; Y =

2.1 Recommended Dosage For patients weighing 50 kg or more: Administer 1,000 mg of Monoferric by intravenous infusion over at least 20 minutes as a single dose. Repeat dose if iron deficiency anemia reoccurs. For patients weighing less than 50 kg: Administer Monoferric as 20 mg/kg actual body weight by intravenous infusion over at least 20 minutes as a single dose. Repeat dose if iron deficiency anemia reoccurs. The dosage of Monoferric is expressed in mg of elemental iron. Each mL of Monoferric contains 100 mg of elemental iron. Only administer Monoferric when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions ( Warnings and Precautions (5.1) ) .

2.2 Preparation and Administration Inspect parenteral drug products visually for the absence of particulate matter and discoloration prior to administration. The product contains no preservatives. Each vial of Monoferric is single-dose only. Discard unused portion. Withdraw the appropriate volume of Monoferric and dilute in 100 mL to 500 mL of 0.9% Sodium Chloride Injection, USP. Final diluted concentration should be more than 1 mg iron/mL. Compatibility of Monoferric with other drugs has not been established. Monoferric should not be mixed with or physically added to solutions containing other drugs. Administer the prepared solution via intravenous infusion over at least 20 minutes. Following dilution with 0.9% Sodium Chloride Injection, USP, Monoferric solution may be stored at room temperature for up to 8 hours. Extravasation of Monoferric may cause brown discoloration at the extravasation site which may be long lasting. Monitor for extravasation. If extravasation occurs, discontinue the Monoferric administration at that site.

Monoferric is contraindicated in patients with a history of serious hypersensitivity to Monoferric or any of its components (see Warnings and Precautions (5.1) , Description (11) ) . Reactions have included shock, clinically significant hypotension, loss of consciousness, and/or collapse. Serious hypersensitivity to Monoferric or any of its components. ( 4 )

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in clinical practice. The safety of Monoferric was evaluated in 3008 patients with iron deficiency anemia enrolled in two randomized, actively-controlled trials.

Trial

1 enrolled adult patients with iron deficiency anemia with intolerance to oral iron or had an unsatisfactory response to oral iron with a clinical need for repletion of iron stores. Eligible subjects were required to have a baseline hemoglobin of ≤11g/dl, transferrin saturation (TSAT) of less than 20% and serum ferritin level of <100 ng/mL.

Trial

2 enrolled adult patients with non-dialysis dependent chronic kidney disease (CKD) with iron deficiency anemia ( see Clinical Studies (14) ). Eligible subjects also had to have serum ferritin ≤100 ng/mL or ≤300 ng/mL if TSAT ≤30%.

Trial

1 and Trial 2 In the two randomized, actively-controlled clinical trials, Trial 1 and Trial 2 (see Clinical Studies (14) ) , patients were randomized in a 2:1 ratio to intravenous Monoferric (n = 2008) or intravenous iron sucrose (n = 1000) respectively. Monoferric was administered as a single intravenous infusion of 1000 mg diluted in 100 mL 0.9 % sodium chloride and given over approximately 20 minutes (approximately 50 mg iron/min). Iron sucrose was administered as 200 mg undiluted intravenous injections over approximately 2-5 minutes and repeated according to standard practice or physician choice up to a maximum of five times (1000 mg) within the first two weeks starting at baseline. The data described below reflect exposure to Monoferric in 2008 patients exposed to a 1000 mg single intravenous dose of Monoferric. The mean cumulative intravenous Iron exposure was 984 mg.

Trial

1 included 1483 patients with iron deficiency anemia in the safety analysis that had intolerance to oral iron or have had unsatisfactory response to oral iron or with a clinical need for rapid repletion of iron stores.

Trial

2 included 1525 patients in the safety analysis who had non-dialysis dependent CKD. The mean (SD) age of the combined study population was 56.4 (18.3) years. The majority of patients were women (75.7%). Adverse reactions were reported in 8.6% (172/2008) of patients treated with Monoferric. Adverse reactions related to treatment and reported by ≥1% of the treated patients in the combined analysis of Trial 1 and 2 are listed in Table 1.

6.2 Post-marketing Experience Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reactions have been most commonly reported from the post-marketing spontaneous reports with Monoferric: Cardiac disorders: Tachycardia Gastrointestinal disorders: Abdominal pain, nausea and vomiting, constipation, diarrhea General disorders and administration site conditions: Fatigue, pyrexia, chest pain, chills, Fishbane reaction, extravasation, influenza like symptoms, injection site reactions, malaise, pain Immune System disorders: Anaphylactic/anaphylactoid reaction, hypersensitivity Investigations: Hepatic enzymes increased Musculoskeletal and connective tissue disorders: Back pain, muscle spasms, arthralgia, myalgia Nervous system disorders: Dizziness, headache, paresthesia, dysgeusia, seizure, loss of consciousness, syncope Psychiatric disorders: Anxiety Respiratory, thoracic and mediastinal disorders: Dyspnea, cough, bronchospasm Skin and subcutaneous tissue disorders: Erythema, urticaria, discoloration skin, rash, pruritus, skin exfoliation, angioedema, sweating Vascular disorders: Hypertension, hypotension, flushing, phlebitis Extravasation of Monoferric at the injection site that may lead to irritation of the skin and potentially long lasting brown discoloration at the site of injection has also been reported.

AND PRECAUTIONS Hypersensitivity Reactions: Monitor patients for signs and symptoms of hypersensitivity during and after Monoferric administration for at least 30 minutes and until clinically stable following completion of the infusion. ( 5.1 )

Iron

Overload: Do not administer Monoferric to patients with iron overload. ( 5.2 )

5.1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Monoferric. Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse. Monitor patients for signs and symptoms of hypersensitivity during and after Monoferric administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Monoferric when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Monoferric is contraindicated in patients with prior serious hypersensitivity reactions to Monoferric or any of its components ( see Contraindications (4) ). In clinical trials in patients with IDA and CKD, serious or severe hypersensitivity were reported in 0.3% (6/2008) of the Monoferric treated subjects. These included 3 events of hypersensitivity in 3 patients; 2 events of infusion-related reactions in 2 patients and 1 event of asthma in one patient.

5.2 Iron Overload Excessive therapy with parenteral iron can lead to excess iron storage and possibly iatrogenic hemosiderosis or hemochromatosis. Monitor the hematologic response (hemoglobin and hematocrit) and iron parameters (serum ferritin and transferrin saturation) during parenteral iron therapy. Do not administer Monoferric to patients with iron overload (see Overdosage (10) ) .
