Mechanism of action of AURYXIA

Watch this video and see how AURYXIA, an oral iron tablet, works in adult patients.

Chronic kidney disease, CKD, is characterized by a gradual loss of kidney function, causing insufficient synthesis of erythropoietin, a hormone that stimulates red blood cell (RBC) production and a lack of which causes anemia.1 Iron deficiency also causes anemia in CKD patients.1

AURYXIA is a unique formulation of ferric citrate coordination complexes that treats iron deficiency anemia in adults with CKD not receiving dialysis.2-4

Upon swallowing AURYXIA, ferric iron is converted to ferrous iron by the enzyme ferric reductase in the gastrointestinal tract, where the molecules are absorbed in the same highly regulated physiological pathway as dietary iron.2,3,5,6 In the bloodstream, ferrous iron is oxidized back to ferric iron, which binds to transferrin, an iron transfer protein that transports iron to the bone marrow for incorporation into hemoglobin for RBC production.2,3,5-7

AURYXIA treats iron deficiency anemia in non-dialysis patients with CKD.2,3

How AURYXIA works to treat iron deficiency anemia

AURYXIA is a unique formulation of ferric citrate coordination complexes that treats iron deficiency anemia in adults with CKD not receiving dialysis.2-4

Ferric iron from the AURYXIA tablet is converted to ferrous iron by the enzyme ferric reductase in the gastrointestinal tract (GI tract)2,3,6
The ferrous iron molecules are absorbed by the GI tract the same way as dietary iron2,5
In the blood, the ferrous iron is oxidized back to ferric iron2,3,5,6
Transferrin binds to the ferric iron and transports it to the bone marrow for incorporation into hemoglobin for RBC production2,3,5-7

Indication

AURYXIA® (ferric citrate) is indicated for:

  • The treatment of iron deficiency anemia in adult patients with chronic kidney disease not on dialysis

Important Safety Information

Contraindication

AURYXIA® (ferric citrate) is contraindicated in patients with iron overload syndromes, e.g., hemochromatosis

Warnings and Precautions

  • Iron Overload: Increases in serum ferritin and transferrin saturation (TSAT) were observed in clinical trials with AURYXIA in patients with chronic kidney disease (CKD) on dialysis treated for hyperphosphatemia, which may lead to excessive elevations in iron stores. Assess iron parameters prior to initiating AURYXIA and monitor while on therapy. Patients receiving concomitant intravenous (IV) iron may require a reduction in dose or discontinuation of IV iron therapy
  • Risk of Overdosage in Children Due to Accidental Ingestion: Accidental ingestion and resulting overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Advise patients of the risks to children and to keep AURYXIA out of the reach of children

Adverse Reactions

The most common adverse reactions reported with AURYXIA in clinical trials were:

  • Iron Deficiency Anemia in CKD Not on Dialysis: Discolored feces (22%), diarrhea (21%), constipation (18%), nausea (10%), abdominal pain (5%) and hyperkalemia (5%)

Specific Populations

  • Pregnancy and Lactation: There are no available data on AURYXIA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. However, an overdose of iron in pregnant women may carry a risk for spontaneous abortion, gestational diabetes and fetal malformation. Data from rat studies have shown the transfer of iron into milk, hence, there is a possibility of infant exposure when AURYXIA is administered to a nursing woman
