Keryx Biopharmaceuticals Announces Second Quarter 2017 Financial Results and Increased 2017 U.S. Product Sales Guidance


BOSTON, July 27, 2017 (GLOBE NEWSWIRE) — Keryx Biopharmaceuticals, Inc. (Nasdaq:KERX), a biopharmaceutical company focused on bringing innovative medicines to people with renal disease, today announced its financial results for the quarter ended June 30, 2017. The company also reviewed its commercial progress with Auryxia and upcoming milestones.

“Our second quarter results reflect continued strong Auryxia prescription demand,” said Greg Madison, president and chief executive officer of Keryx. “This demand was largely driven by solid execution across our entire field team, which increased both breadth and depth of prescribing among physicians. With this momentum, we have increased our annual net Auryxia product sales guidance, reflecting improved confidence in our ability to bring this medicine to a greater number of people with chronic kidney disease (CKD) on dialysis this year.”

Mr. Madison continued, “We are equally excited about the opportunity to potentially add a second indication for Auryxia for the treatment of iron deficiency anemia in people with non-dialysis dependent chronic kidney disease. Iron deficiency anemia is a serious disease and, today, as many as three out of four people with CKD and iron deficiency anemia are not being optimally treated with existing iron supplements. Our team is working diligently to ensure that we are prepared, pending FDA approval in early November, for a successful launch in this indication. I believe the progress we are making in dialysis coupled with the large opportunity to treat iron deficiency anemia form a strong foundation from which to build a leading renal company.”

Second Quarter June 30, 2017 Financial Results
“The second quarter, highlighted by reported strong demand and sales of Auryxia, gives us the confidence to raise Auryxia’s 2017 net product sales guidance to $62 to $66 million,” said Scott Holmes, senior vice president and chief financial officer of Keryx Biopharmaceuticals. “Additionally, the capital raised via the ATM strengthens our balance sheet and provides us with the financial flexibility to continue to appropriately invest in our business to support our anticipated growth.”

Total revenues for the quarter ended June 30, 2017 were $15.1 million, compared with $9.3 million during the same period in 2016. Total revenues for the second quarter of 2017 include $14.1 million in net U.S. Auryxia product sales, compared to $8.3 million in the second quarter of 2016. Total revenues also include $1.0 million in license revenue during the second quarters of 2017 and 2016.

Cost of goods sold for the quarter ended June 30, 2017 were $4.4 million, compared with $5.1 million during the same period in 2016.

Selling, general and administrative expenses for the quarter ended June 30, 2017 were $25.0 million, as compared to $20.2 million during the same period in 2016. The increase was related to the continued commercialization of Auryxia, and preparations for Auryxia’s potential launch in iron deficiency anemia later this year.

Research and development expenses for the quarter ended June 30, 2017 were $9.0 million, as compared to $7.0 million during the same period in 2016. The increase was primarily related to manufacturing and clinical activities to support the long-term growth of Auryxia.

Net loss for the quarter ended June 30, 2017 was $86.5 million, or $0.77 per share, compared to a net loss of $44.7 million, or $0.42 per share, for the comparable period in 2016. The increase in net loss is attributable to the recognition of $63.0 million of non-cash debt discount amortization related to the company’s outstanding convertible debt. This amortization expense is not expected to recur in future periods. 

Cash and cash equivalents as of June 30, 2017 totaled $140.5 million compared to $111.8 million as of December 31, 2016.

The guidance is based on the company’s current understanding of Auryxia prescriptions trends in dialysis and other financial factors. Guidance excludes any sales from the potential approval in November 2017 of the second indication for ferric citrate in the U.S.

About Iron Deficiency Anemia, NDD-CKD
Iron deficiency anemia (IDA) is a common complication in patients with non-dialysis dependent chronic kidney disease (NDD-CKD), and the prevalence and severity of IDA increases as kidney disease progresses. Today, there are no FDA approved oral irons for the treatment of IDA in CKD patients and the efficacy and tolerability of current oral iron supplements are mixed. The company estimates that of the 1.7 million Americans with CKD under the care of a nephrologist, approximately 650,000 people are treated for IDA and another 250,000 – 400,000 people could have IDA but are not treated today.

About Auryxia
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 CKD on dialysis. The U.S. approval of Auryxia was based on data from the company’s Phase 3 registration program in dialysis patients. 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). 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. For more information about Auryxia and the U.S. full prescribing information, visit

Use of ferric citrate in patients with IDA, NDD-CKD, as highlighted above, is investigational and has not been determined to be safe or efficacious.

Contraindication: Patients with iron overload syndrome, e.g. hemochromatosis, should not take Auryxia®.

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. Ciprofloxacin should be taken at least 2 hours before or after Auryxia.

Forward-Looking Statements  
Some of the statements included in this press release, particularly those regarding the commercialization and ongoing clinical development of Auryxia, our updated 2017 financial guidance and the submission of an sNDA to the FDA to expand the label of ferric citrate to include the treatment of IDA in adults with stage 3-5 NDD-CKD and the potential approval in this indication and the impact thereof on Keryx, may be forward-looking statements that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
