BOSTON, June 24, 2015 (GLOBE NEWSWIRE) -- Keryx Biopharmaceuticals, Inc. (Nasdaq: KERX ), a biopharmaceutical company focused on bringing innovative therapies to market for people with renal disease, today announced that two national insurance providers have added Auryxia™ to their Medicare Part D formularies. Auryxia is the first and only absorbable, iron-based phosphate binder for the treatment of elevated serum phosphorus levels in people with chronic kidney disease on dialysis. Together, these new formularies will increase unrestricted access to Auryxia, across Medicare Part D and commercial insurance providers, to approximately 65 percent of people in the U.S. currently taking phosphate binders.
"The inclusion of Auryxia on these major insurance providers' Part D formularies, which we expect will start processing claims in the third quarter, significantly expands unrestricted access to Auryxia for people on dialysis and their caregivers," said Greg Madison, Chief Executive Officer of Keryx Biopharmaceuticals. "We are progressing nicely towards our goal of broad, unrestricted access to approximately 80 percent of phosphate binder prescriptions, across both Medicare Part D and commercial insurance providers, within 12 months post-approval. Looking ahead, we are focused on continuing to raise awareness of Auryxia's clinical profile among the prescribing community and ensuring that the vast majority of dialysis patients have access to this important medicine."
Auryxia is currently approved to treat elevated serum phosphorus levels in the estimated 450,000 people in the U.S. who have End Stage Renal Disease (ESRD) and require dialysis treatment. The majority of ESRD patients require chronic treatment with phosphate-binding medicines to lower and maintain serum phosphorus at acceptable levels. Medicare Part D and commercial insurance providers cover most of the healthcare costs for people with ESRD and account for approximately 90 percent of all prescriptions for phosphate binders, with Part D alone representing more than 60 percent of all phosphate binder prescriptions.
About Auryxia™ (ferric citrate)
Auryxia™ (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. The U.S. approval of Auryxia was based on data from the Company's Phase 3 registration program. In the Phase 3 clinical trials, Auryxia effectively reduced serum phosphorus levels to within the KDOQI guidelines range of 3.5 to 5.5 mg/dL.
Auryxia binds with dietary phosphate in the GI tract and precipitates as ferric phosphate. The unbound portion of Auryxia has been shown to increase serum iron parameters including ferritin and transferrin saturation (TSAT), whereas these parameters remained relatively constant in patients treated with active control (Renvela® and/or Phoslo®). Iron absorption from Auryxia may lead to excessive elevations in iron stores. Accordingly, physicians should assess and monitor iron parameters before starting and while on Auryxia, and may need to decrease or discontinue IV iron for these patients. The most common adverse events for Auryxia treated patients were gastrointestinal-related, including diarrhea, nausea, vomiting and constipation.

Auryxia™ (ferric citrate) Important Safety Information
Contraindication: Patients with iron overload syndrome, e.g. hemochromatosis, should not take Auryxia™ (ferric citrate).
Iron Overload: Iron absorption from Auryxia may lead to increased iron in storage sites. Iron parameters should be monitored prior to and while on Auryxia. Patients receiving IV iron may require a reduction in dose or discontinuation of IV iron therapy.
Accidental Overdose of Iron: Accidental overdose of iron containing products is a leading cause of fatal poisoning in children under 6 years of age. Keep Auryxia away from children as it contains iron. 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 Auryxia were diarrhea (21%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%). Gastrointestinal adverse reactions were the most common reason for discontinuing Auryxia (14%). Auryxia 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 Auryxia.
