About Ferric Citrate

Ferric Citrate was approved by the U.S. Food and Drug Administration on September 5, 2014 and is indicated in the U.S. for the control of serum phosphorus levels in patients with chronic kidney disease (CKD) on dialysis. Keryx plans to make Ferric Citrate available to U.S. dialysis patients in early December.

In January 2014, ferric citrate was approved for the treatment of patients with all stages of CKD in Japan, where it is being marketed as Riona® by Keryx's Japanese partner, Japan Tobacco Inc. and Torii Pharmaceutical Co. Ltd.

Keryx has filed a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA), seeking the approval of Ferric Citrate as a treatment of hyperphosphatemia in patients with CKD, including dialysis and non-dialysis dependent patients, and that application is currently under review.

Ferric Citrate is also being developed in the U.S. as a treatment for iron deficiency anemia in patients with Stage 3 to 5 non-dialysis dependent chronic kidney disease (CKD). The pivotal Phase 3 study in this indication commenced in September 2014.

Important Safety Information about Ferric Citrate

Contraindication: Patients with an accumulation of iron in their body, e.g. hemochromatosis, should not take Ferric Citrate.

Iron Overload: Iron absorption from Ferric Citrate may lead to increased iron in storage sites. Iron parameters should be monitored prior to and while on Ferric Citrate. Patients receiving IV iron may require a reduction in dose or discontinuation of IV iron therapy.

Accidental Overdose of Iron: Keep Ferric Citrate away from children as it contains iron. Accidental overdose of iron containing products is a leading cause of fatal poisoning in children under 6 years of age. Call a poison control center or your physician in case of an accidental overdose in a child.

Patients with Gastrointestinal Bleeding or Inflammation: Safety has not been established for these patients.

Adverse Events: The most common adverse events with Ferric Citrate were diarrhea (21%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%). Gastrointestinal adverse reactions were the most common reason for discontinuing Ferric Citrate (14%).

Ferric Citrate contains iron and may cause dark stools, which is considered normal with oral medications containing iron.

Drug Interactions: Doxycycline should be taken at least 1 hour before Ferric Citrate.
