--Company to Host Conference Call Today at 4:30 p.m. Eastern Time--

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Aug. 8, 2018-- Akebia Therapeutics, Inc. (Nasdaq: AKBA), a biopharmaceutical company focused on delivering innovative therapies to patients with kidney disease through the biology of hypoxia-inducible factor (HIF), today announced financial results for the second quarter ended June 30, 2018.

“In the second quarter, we continued to drive our Phase 3 vadadustat program while executing on our long-term growth strategy with the announcement of the pending merger with Keryx Biopharmaceuticals,” said John P. Butler, President and Chief Executive Officer of Akebia Therapeutics. “The combination is expected to create a fully-integrated company focused on the development and commercialization of therapeutics for patients with kidney disease. We are actively engaged in integration planning and continue to target the closing of the transaction by the end of 2018.”

Second Quarter 2018 and Recent Corporate Highlights

Merger Announcement:

• The definitive merger agreement with Keryx Biopharmaceuticals, Inc. (Nasdaq: KERX) was announced, offering potential operating and product portfolio synergies and the opportunity to create significant value and accelerate the growth potential beyond what either company would achieve separately;
• The combined company will have an expanded and highly complementary nephrology portfolio, with Auryxia^® (ferric citrate), a U.S. Food and Drug Administration (FDA)-approved product in two indications with significant growth opportunity, and vadadustat, an investigational late-stage hypoxia-inducible factor prolyl hydroxylase inhibitor, which has the potential to provide a new oral standard of care to patients with anemia due to chronic kidney disease (CKD);
• The combined company will have an established renal development, manufacturing and commercial organization, positioning it as a partner of choice for the renal community and for companies developing renal products; and
• The combined company plans to leverage its leadership’s extensive expertise in the commercial renal market with the goal of maximizing sales of Auryxia while driving launch momentum for vadadustat in the United States, subject to FDA approval.

Clinical Development:

• Completed U.S. enrollment of the Phase 3 INNO₂VATE Conversion study, targeting full enrollment of the INNO₂VATE program globally by the end of 2018. The company expects top-line results for the program in the fourth quarter of 2019 or the first quarter of 2020, subject to the accrual of major adverse cardiac events (MACE);
• Continued to enroll subjects in the Phase 3 PRO₂TECT program, with top-line results anticipated in mid-2020, subject to the accrual of MACE;
• Initiated the Phase 2 FO₂RWARD-2 study in dialysis dependent patients with anemia due to CKD, with top-line results expected in the first half of 2019. Results from this study are expected to provide additional characterization and differentiation of vadadustat and may further strengthen the company’s commercial position, subject to vadadustat’s regulatory approval; and
• Completed a type-C meeting with the FDA, in which Akebia and the agency aligned on the statistical analysis plan in advance of a planned NDA filing for vadadustat.

Financial Results

Akebia reported a net loss of $34.1 million, or ($0.60) per share, for the second quarter of 2018 as compared to a net loss for the second quarter of 2017 of $21.5 million or ($0.53) per share.

Collaboration revenue was $48.8 million for the second quarter of 2018 compared to $28.5 million for the second quarter of 2017. Collaboration revenue recognized in the second quarter of 2018 related to revenue recognized under both the collaboration agreement with Otsuka Pharmaceutical Co. Ltd., or Otsuka, related to the United States, or the Otsuka U.S. Agreement, and the collaboration agreement with Otsuka related to Europe, China and certain other regions, or the Otsuka International Agreement, as well as revenue recognized in connection with the collaboration agreement with Mitsubishi Tanabe Pharma Corporation. Collaboration revenue recognized in the second quarter of 2017 only related to the Otsuka U.S. Agreement and the Otsuka International Agreement, which were consummated in December 2016 and April 2017, respectively.

Research and development expenses were $71.9 million for the second quarter of 2018 compared to $43.8 million for the second quarter of 2017. The increase was primarily attributable to external costs related to the continued advancement of the global PRO₂TECT and INNO₂VATE Phase 3 programs, including enrollment; and the manufacture of drug substance and drug product in support of the global Phase 3 program. Research and development expenses were further increased by headcount and compensation-related costs.

General and administrative expenses were $12.5 million for the second quarter of 2018 compared to $6.9 million for the second quarter of 2017. The increase was primarily attributable to an increase in costs to support the company’s research and development programs, including headcount and compensation-related costs, and costs incurred related to the proposed merger with Keryx Biopharmaceuticals.

Akebia ended the second quarter of 2018 with cash, cash equivalents and available for sale securities of $402.1 million. The company also generally receives cost-share funding from its collaboration agreements with Otsuka on a prepaid quarterly basis. Akebia expects its existing cash resources, including the prepaid quarterly committed cost-share funding from its collaborators, to fund its current operating plan into the first quarter of 2020.
