"We continued to see significant growth year-over-year in the number of prescriptions written and the revenue generated by Auryxia," said Jodie Morrison, interim chief executive officer of Keryx Biopharmaceuticals. "We are continuing to make progress on consummating our merger with Akebia and have scheduled a stockholder meeting to approve the transaction for December 11, 2018.

Business Highlights
Net U.S. Auryxia product sales were $26.6 million in the third quarter of 2018, as compared to $13.6 million in the same quarter in 2017, representing growth of 96 percent.
Approximately 47,500 Auryxia prescriptions were reported in the third quarter of 2018, representing 9.4 million Auryxia tablets. This compares to approximately 25,200 prescriptions and 5.4 million Auryxia tablets in the third quarter of 2017.
Auryxia market share for the third quarter of 2018 was 6.4 percent, compared to 3.5 percent in the third quarter of 2017.
The breadth of physicians prescribing Auryxia continued to expand in the third quarter of 2018 compared to the same period in 2017, with approximately 6,500 prescribers in the 2018 quarter, nearly 2,000 more than the third quarter of 2017.
The depth of Auryxia prescribing also increased significantly in the third quarter of 2018, with a 28 percent increase in the average number of prescriptions per prescriber as compared to the third quarter of 2017.
As expected, there was a shift in channel mix for Auryxia during the third quarter of 2018, with 61 percent of prescriptions coming through IMS reporting channels and 39 percent coming through specialty pharmacies (including Fresenius Rx and Davita Rx); the shift in mix is due the closing of Davita’s specialty pharmacy business, which occurred in September 2018.
The gross-to-net adjustment for Auryxia for the third quarter of 2018 was 50 percent. This is consistent with year-to-date 2018 gross-to-net adjustment of 50 percent.
Akebia Merger Update
On June 28, 2018, Keryx announced that it had entered a definitive merger agreement with Akebia Therapeutics, Inc. that is expected to close by the end of 2018, subject to stockholder approvals and satisfaction of customary closing conditions.
If the merger is consummated, Keryx stockholders would continue to participate in the growth of Auryxia and gain access to an innovative Phase 3 product candidate with the potential to compete in a complementary multi-billion-dollar market, upon successful completion of its development program. The combined company would have substantial financial resources, an integrated platform for the development and launch of renal drugs and be led by a seasoned executive with decades of experience in the renal field.
The definitive proxy materials were filed with the Securities and Exchange Commission (SEC) on October 30, 2018 and the companies’ respective stockholder meetings are scheduled for December 11, 2018 for stockholders of record as of October 22, 2018.
The Keryx Board continues to unanimously support the merger and recommends that stockholders vote FOR the merger proposals at the upcoming stockholders’ meeting.
Given the pending merger with Akebia, Keryx will not be holding a conference call to discuss third quarter 2018 results.

IMPORTANT U.S. SAFETY INFORMATION FOR AURYXIA (ferric citrate)
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
Most common adverse reactions with AURYXIA were:
Hyperphosphatemia in CKD on Dialysis: Diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%)
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.
