Ferric Derisomaltose

Derisofer is an iron replacement product indicated for the treatment of iron deficiency anemia in adult patients:

who have intolerance to oral iron or have had unsatisfactory response to oral iron.

who have non-hemodialysis dependent chronic kidney disease.

This 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 is a complex of iron (III) hydroxide and derisomaltose, an iron carbohydrate oligosaccharide that releases iron. Iron binds to transferrin for transport to erythroid precursor cells to be incorporated into hemoglobin.

For patients weighing 50 kg or more : Administer 1,000 mg of Ferric Derisomaltose 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 Ferric Derisomaltose 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 Ferric Derisomaltose is expressed in mg of elemental iron. Each mL of Ferric Derisomaltose contains 100 mg of elemental iron. Only administer Ferric Derisomaltose when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions

Ferric Derisomaltose is contraindicated in patients with a history of serious hypersensitivity to Ferric Derisomaltose or any of its components. Reactions have included shock, clinically significant hypotension, loss of consciousness, and/or collapse.

Most commonly reported adverse reactions (incidence ≥1%) are rash and nausea.

There are no available data on Ferric Derisomaltose use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Published studies on the use of intravenous iron products in pregnant women have not reported an association with adverse developmental outcomes. However, these studies cannot establish or exclude the absence of any drug-related risk during pregnancy because the studies were not designed to assess for the risk of major birth defects. The available data on the use of Ferric Derisomaltose in lactating women demonstrate that iron is present in breast milk. However, the data do not inform the potential exposure of iron for the breastfed child or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Ferric Derisomaltose in addition to any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition.

Hypersensitivity Reactions : Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Derisofer. 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 Derisofer administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Derisofer when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Derisofer is contraindicated in patients with prior serious hypersensitivity reactions to Derisofer or any of its components. In clinical trials in patients with IDA and CKD, serious or severe hypersensitivity were reported in 0.3% (6/2008) of the Derisofer 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. 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 Derisofer to patients with iron overload

Excessive dosages of Derisofer may lead to the accumulation of iron in storage sites potentially leading to hemosiderosis and hemochromatosis. Avoid use of Derisofer in patients with iron overload.

Store at 20° to 25°C; excursions permitted to 15° to 30°C. Do not freeze.
