CAMBRIDGE,Mass.--May 9, 2019— Akebia Therapeutics, Inc. (Nasdaq: AKBA), a biopharmaceutical company focused on the development and commercialization of therapeutics for patients with kidney disease, today reported financial results for the first quarter ended March 31, 2019. The company also announced full enrollment of its global Phase 3 INNO₂VATE studies for vadadustat, that it has bolstered its commercial capabilities with the addition of Dell Faulkingham as Senior Vice President, Chief Commercial Officer, and appointed Steven K. Burke, M.D., as Senior Vice President, Chief Medical Officer.

“The first quarter marked the achievement of another important milestone for Akebia with the announcement of positivetop-line results from two Phase 3, active-controlled, pivotal studies evaluating vadadustat in Japanese patients with anemia due to chronic kidney disease (CKD),” stated John P. Butler, President and Chief Executive Officer of Akebia Therapeutics. “We are excited by these results as they increase our level of confidence in the hypoxia inducible factor (HIF) pathway and more specifically, the direction of our clinical program for vadadustat. These results are expected to serve as the basis for a New Drug Application in Japan (JNDA) by our collaboration partner, Mitsubishi Tanabe Pharma Corporation (MTPC), in 2019.”

Butler continued, “We are also pleased to announce the completion of enrollment in our global Phase 3 INNO₂VATE studies evaluating vadadustat for the treatment of anemia due to CKD in dialysis-dependent CKD subjects. With the addition of Dell Faulkingham to our executive team, we have strengthened our commercial capabilities and believe we are well positioned to execute on our revenue growth strategies for Auryxia. Lastly, we look forward to welcoming Dr. Steven Burke as our new Chief Medical Officer as we continue to execute on the multiple catalysts expected with vadadustat’s Phase 3 program over the next 12 to 18 months.”

Auryxia Highlights

• Auryxia net product revenue for the first quarter of 2019 was $23.1 million, representing 12.1 percent growth over the first quarter of 2018.

• Total Auryxia prescriptions were 40,080, representing 22.5 percent growth over the first quarter of 2018.

Vadadustat Highlights

• Announced positivetop-line results from two Phase 3, active-controlled, pivotal studies evaluating vadadustat in Japanese subjects with anemia due to CKD in March 2019. Data from these two pivotal studies as well as from two additionalsingle-arm studies in peritoneal dialysis and hemodialysis subjects, also recently announced, are expected to serve as the basis for a JNDA submission by MTPC in 2019.

• Expanded license agreement with Vifor Pharma announced in April 2019 creates opportunity for accelerated introduction of vadadustat, if approved by the U.S. Food and Drug Administration (FDA), in up to 60 percent of U.S. dialysis patients.

• Enrollment in the global Phase 3 INNO₂VATE studies evaluating the safety and efficacy of vadadustat in dialysis-dependent CKD subjects with anemia due to CKD, has been completed. Enrollment in the smaller of the two INNO₂VATE studies (the “Correction Study”), was completed in April 2019, with a total of 369 subjects enrolled. Enrollment in the larger INNO₂VATE study (the “Conversion Study”) was completed in February 2019, with a total of 3,554 subjects enrolled. The company continues to expect to reporttop-line data from both INNO₂VATE studies in the second quarter of 2020, subject to the accrual of major adverse cardiovascular events (MACE).

• The company expects enrollment in the global Phase 3 PRO₂TECT studies evaluating the safety and efficacy of vadadustat innon-dialysis dependent CKD subjects with anemia due to CKD, to be completed in 2019, with up to approximately 3,700 subjects expected to be enrolled. The company continues to expect to reporttop-line results inmid-2020, subject to the accrual of MACE.

Financial Results

Total revenue for the first quarter of 2019 was $72.7 million, compared to $45.9 million in the first quarter of 2018.

Auryxia net product revenue for the first quarter of 2019 was $23.1 million, compared to $20.6 million, as reported by Keryx Biopharmaceuticals, Inc. (“Keryx”) prior to its merger with the company, during the same period in 2018. This represents a 12.1 percent increase in net product revenue from the first quarter of 2018. Auryxia is the company’s FDA approved oral iron tablet to treatnon-dialysis dependent adult CKD patients for iron deficiency anemia (IDA) and dialysis-dependent adult CKD patients for hyperphosphatemia.

“As we previously discussed, the Centers for Medicare & Medicaid Services’ (CMS) new prior authorization requirement for Auryxia caused delays in approvals of prescriptions and negatively impacted Auryxia product revenue for the first quarter. We believe our efforts to help patients and prescribers navigate this process are working and we’re encouraged with the growth in weekly prescriptions that we are now seeing. In fact, the prescription demand we’ve seen in the first four weeks of the second quarter exceeded the first four weeks of any quarter since Auryxia was launched,” stated Butler. “Looking ahead, we believe continued execution on our growth strategy and underlying market demand, will drive increased revenue for Auryxia in the second quarter and across the year.”

Collaboration revenue for the first quarter of 2019 was $49.6 million, compared with $45.9 million in the first quarter of 2018. The increase was primarily due to increased collaboration revenue in the first quarter of 2019 from the company’s cost sharing arrangement under its Otsuka collaboration agreements. The company expects Otsuka to begin funding 80 percent of its development costs for vadadustat in the second quarter of 2019.

Cost of goods sold was $31.3 million for the first quarter of 2019, consisting of $7.6 million of costs associated with the manufacture of Auryxia and $23.7 million related to the application of purchase accounting as a result of the merger with Keryx, including $14.6 million of inventorystep-up and $9.1 million of amortization of intangibles.

Research and development expenses were $82.4 million for the first quarter of 2019 compared to $61.4 million for the first quarter of 2018. The increase was primarily attributable to an increase in external costs related to the continued advancement of the PRO₂TECT and INNO₂VATE Phase 3 studies.

Selling, general and administrative expenses were $34.3 million for the first quarter of 2019 compared to $9.0 million for the first quarter of 2018. The increase in selling, general and administrative expenses was primarily attributable to commercialization costs associated with Auryxia, as there were no comparable commercialization costs in the first quarter of 2018.

The company reported a net loss for the first quarter of 2019 of $72.4 million, or ($0.62) per share, as compared to a net loss of $23.4 million, or ($0.48) per share, for the first quarter of 2018. The company’s net loss for the first quarter of 2019 includes the impact of merger-related accounting charges totaling $23.7 million, offset by a $2.8 million deferred tax benefit.

The company ended the quarter with cash, cash equivalents andavailable-for-sale securities of $168.0 million. The decrease from the fourth quarter of 2018 was primarily related to the timing of cash flows between quarters, including reimbursement amounts from the company’s collaboration partners and payments related to its Phase 3 program for vadadustat, including $13.0 million of advanced purchases of comparator drug inventory in anticipation of Brexit. Additionally, cash was impacted byone-time payments of certain previously accrued, merger-related liabilities totaling $30.0 million. The company continues to expect its cash resources, including the prepaid quarterly committed cost-share funding from its collaboration partners, to fund its current operating plan into the third quarter of 2020.

About Vadadustat

Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor currently in global Phase 3 development for the treatment of anemia due to CKD. Vadadustat’s proposed mechanism of action is designed to mimic the physiologic effect of altitude on oxygen availability. At higher altitudes, the body responds to lower oxygen availability with increased production of hypoxia-inducible factor, which coordinates the interdependent processes of iron mobilization and erythropoietin production to increase red blood cell production and, ultimately, improve oxygen delivery. Vadadustat is an investigational therapy and is not approved by the U.S. Food and Drug Administration (FDA) or any regulatory authority.

About Auryxia^® (ferric citrate) Tablets

Auryxia (ferric citrate) was approved by the FDA on September 5, 2014 for the control of serum phosphorus levels in adult patients with CKD on dialysis and approved by the FDA on November 6, 2017 for the treatment of iron deficiency anemia in adult patients with CKD not on dialysis. For more information about Auryxia and the U.S. full prescribing information, please visit www.auryxia.com.

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.

To report suspected adverse reactions, contact AkebiaTherapeutics at 1-844-445-3799.
