• Vadadustat achieves primary efficacy and cardiovascular safety endpoints
• Company’s cash runway extends well into 2021
• Company to host conference call today at 8:30 a.m. ET to discuss top-line data and its first quarter results

CAMBRIDGE, Mass., May 5, 2020 /PRNewswire/ -- Akebia Therapeutics, Inc. (Nasdaq: AKBA), today announced positive top-line results from INNO₂VATE, its global Phase 3 cardiovascular outcomes program evaluating the efficacy and safety of vadadustat, its investigational oral hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), versus darbepoetin alfa for the treatment of anemia due to chronic kidney disease (CKD) in adult patients on dialysis. (Please refer to Akebia’s INNO₂VATE Data Announcement for the top-line data.) The Company also reported financial results for the first quarter ended March 31, 2020 and will host a conference call with slides today, Tuesday, May 5, 2020, at 8:30 a.m. Eastern Time to discuss INNO₂VATE top-line data, its first quarter financial results and recent business highlights.

“We are very excited about the positive top-line results from INNO₂VATE and expect to build on this momentum with many potentially transformational near-term milestones,” said John P. Butler, President and Chief Executive Officer of Akebia Therapeutics. “We believe we’ve developed an exciting path forward for vadadustat and although the COVID-19 environment remains unpredictable, we continue to execute and deliver solid progress against these initiatives. In collaboration with our partner, Mitsubishi Tanabe, we are advancing key pre-commercial activities in support of the first regulatory approval of vadadustat expected in Japan this year. We have also significantly advanced PRO₂TECT, our global Phase 3 studies evaluating the safety and efficacy of vadadustat in adult patients not on dialysis with anemia due to CKD, and expect to report top-line data from these studies mid-year, as planned. In addition, we reinforced our intellectual property position for vadadustat, confirming the path for Akebia and our collaboration partner, Otsuka, to launch vadadustat in the U.K. and potentially the rest of Europe, upon approval.”

“Akebia continues to provide and support our innovative therapies, which are critical to the care of adult patients with CKD, who are among the most at risk during this pandemic. To date, we have not experienced any significant adverse impact from COVID-19 and our fundamentals remain strong with a cash runway that extends well into 2021. However, these are unprecedented times and, due to COVID-19, we do not have clear visibility on how product demand and payer mix may be impacted. As a result, we continue to actively monitor and assess the potential impact of COVID-19 on our business and operations while continuing to support patients.” Butler concluded, “We believe we have tremendous value-enhancing opportunities ahead and we remain focused on supporting patients and executing on our plans to position Akebia for long term growth.”

Business Highlights

• Today, the Company announced positive top-line results from INNO₂VATE. Please refer to Akebia’s INNO₂VATE Data Announcement for the top-line data.
• In April, the Patents Court of the United Kingdom issued a judgment in favor of Akebia and Otsuka Pharmaceutical Co. Ltd., which found that five of FibroGen, Inc.'s six HIF-related patents were invalid, and a sixth patent would not be infringed.
• In April, the Company announced that Myles Wolf, M.D., M.M.Sc., joined Akebia’s Board of Directors. Dr. Wolf is a leading clinical nephrologist and physician-scientist in the fields of disordered mineral metabolism and cardiovascular disease in patients with CKD. Dr. Wolf serves as Chief of the Division of Nephrology and a Professor of Medicine at Duke University School of Medicine.
• In April, the Company settled Auryxia patent litigation with Teva Pharmaceuticals USA, Inc. (Teva) and its wholly owned, indirect subsidiary, Watson Laboratories, Inc. (Watson), resolving patent litigation brought in response to Abbreviated New Drug Application (ANDA) filings by Teva and Watson. Consistent with the Company’s prior ANDA settlement with Par Pharmaceutical, Inc., the settlement allows Teva and Watson to market its generic version of Auryxia in the United States beginning on March 20, 2025 (subject to U.S. FDA approval), or earlier under certain circumstances customary for settlement agreements of this nature.
• In April, the Company entered into a new supply agreement with STA Pharmaceutical Hong Kong Limited, a subsidiary of Wuxi AppTec (WuXi), under which WuXi will manufacture vadadustat drug substance for commercial use. The WuXi supply agreement is the third commercial supply agreement the Company has entered into for vadadustat. The Company entered into a commercial supply agreement for vadadustat drug substance with Esteve Química, S.A. in April 2019, and a commercial supply agreement for vadadustat drug product with Patheon Inc. in March 2020.
• In April, the United States District Court for the District of Delaware dismissed a putative securities class action brought against the Company’s wholly owned subsidiary, Keryx Biopharmaceuticals, Inc. (Keryx), and former members of Keryx’s board of directors, relating to the Company’s 2018 merger with Keryx in response to a motion to dismiss filed by Keryx and the former directors.
• In February, the Company entered into a letter agreement with Vifor (International) Ltd. (Vifor Pharma) relating to Vifor Pharma’s agreement with a third party to purchase a Priority Review Voucher (PRV) issued by the U.S. Food and Drug Administration (FDA), subject to satisfaction of customary closing conditions. Pursuant to the letter agreement, Akebia paid Vifor Pharma $10 million. Vifor Pharma is obligated to reserve the PRV for the vadadustat NDA for the treatment of anemia due to CKD in dialysis-dependent and non-dialysis dependent patients until Akebia and Vifor Pharma agree on the financial and other terms under which it will assign the PRV to Akebia or make a mutual decision to sell the PRV. A PRV entitles the holder to priority review of an NDA or a Biologics License Application for a new drug, which reduces the target FDA review time to six months after official acceptance of the submission and could lead to expedited approval.

First Quarter Financial Results

• Revenues: Total revenue increased 22 percent to $88.5 million for the first quarter of 2020 compared to $72.7 million for the first quarter of 2019.
  • Collaboration revenue was $59.3 million for the first quarter of 2020 compared to $49.6 million in the first quarter of 2019, an increase of 20 percent.
  • Net product revenue was $29.2 million for the first quarter of 2020 compared with $23.1 million in the first quarter of 2019, an increase of 26 percent.
• COGS: Cost of goods sold was $27.7 million for the first quarter of 2020, which includes non-cash charges, related to the application of purchase accounting as a result of the merger with Keryx, of $11.2 million for inventory step-up and $9.1 million for amortization of intangibles. Cost of goods sold was $31.3 million for the first quarter of 2019, and included non-cash merger-related charges of $14.6 million for inventory step-up and $9.1 million for amortization of intangibles.
• R&D Expenses: Research and development expenses were $81.2 million for the first quarter of 2020 compared to $82.4 million for the first quarter of 2019.
• SG&A Expenses: Selling, general and administrative expenses were $38.0 million for the first quarter of 2020 compared to $34.3 million for the first quarter of 2019.
• Net Loss: Net loss was $60.7 million for the first quarter of 2020 compared to $72.4 million for the first quarter of 2019.
• Cash Position: Cash, cash equivalents and available-for-sale securities as of March 31, 2020 were $115.4 million. The Company’s cash runway extends well into 2021. The Company’s cash runway, consistent with previous commentary, includes the receipt of a $15.0 million regulatory milestone from Mitsubishi Tanabe Pharma Corporation, Akebia’s development and commercialization collaboration partner in Japan for vadadustat, assuming approval of vadadustat in Japan.

“Consistent with our prior first quarter periods, the decrease in the Company’s cash, cash equivalents and available-for-sale securities from year-end 2019 was due to the timing of cash payments from our collaboration partner, Otsuka, for which $49.5 million was received in the current quarter rather than the first quarter of 2020. In addition, during the first quarter, we paid $10 million to Vifor Pharma in connection with Vifor Pharma’s purchase of the PRV,” stated Jason A. Amello, Chief Financial Officer of Akebia.

About Vadadustat
Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor currently in global Phase 3 development for the treatment of anemia due to CKD. Vadadustat is designed to mimic the physiologic effect of altitude on oxygen availability. At higher altitudes, the body responds to lower oxygen availability with stabilization of hypoxia-inducible factor, which can lead to increased red blood cell production and improved oxygen delivery to tissues. Vadadustat is an investigational therapy and is not approved by the U.S. Food and Drug Administration (FDA) or any regulatory authority.

About Anemia due to Chronic Kidney Disease (CKD)
Anemia is a condition in which a person lacks enough healthy red blood cells to carry adequate oxygen to the body’s tissues. It commonly occurs in people with CKD because their kidneys do not produce enough erythropoietin (EPO), a hormone that helps regulate production of red blood cells. Anemia due to CKD can have a profound impact on a person’s quality of life as it can cause fatigue, dizziness, shortness of breath and cognitive dysfunction. Left untreated, anemia leads to deterioration in health and is associated with increased morbidity and mortality in people with CKD.
