Akebia Therapeutics Reports Third Quarter 2023 Financial Results
and Recent Business Highlights

Akebia to host conference call at 8:00 a.m. ET

Vadadustat NDA assigned a PDUFA date of March 27, 2024
Vadadustat approved in 36 countries, including Australia and Taiwan
Akebia strengthens cash position modifying Pharmakon loan
Auryxia® (ferric citrate) quarterly net product revenue of $40.1 million

CAMBRIDGE, Mass.—November 8, 2023—Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today reported financial results for the third quarter ended September 30, 2023 and reviewed recent business highlights.

In September, Akebia completed its resubmission to its New Drug Application for vadadustat to the U.S. Food and Drug Administration (FDA) as a treatment for anemia due to chronic kidney disease (CKD) in adult patients on dialysis. FDA subsequently accepted the resubmission and assigned a user fee goal date ("PDUFA date") of March 27, 2024. The resubmission includes post-marketing safety data from tens of thousands of patients in Japan where vadadustat is approved and has been in the market for more than three years.

“Akebia is extremely well-positioned following the acceptance of our vadadustat NDA resubmission, with a March 27, 2024 PDUFA date,” said John P. Butler, Chief Executive Officer of Akebia. "We are preparing for a commercial launch if vadadustat is approved and stand ready with a commercial team in place and product supply on the shelf. We also added Australia and Taiwan to the list of countries where vadadustat is approved for CKD patients on dialysis. Additionally, we have strengthened our financial position by deferring our Pharmakon principal payments until October 2024.”

Auryxia® (ferric citrate) net product revenue for the third quarter was $40.1 million and management reaffirms previously issued 2023 net product revenue guidance of $170.0 - $175.0 million for Auryxia.

Third Quarter 2023 and Recent Business Highlights

Australia’s Therapeutic Goods Administration granted approval for Vafseo® (vadadustat) for the treatment of anemia associated with CKD in adults on chronic maintenance dialysis. Vadadustat was also authorized for use in Taiwan during this time, marking approval in 36 countries.
Akebia supported five posters presented at the American Society of Nephrology Kidney Week 2023, which took place on November 2-5, 2023. Notably, one poster presented data on a potential alternative dosing regimen for vadadustat.
Akebia modified the terms of its loan agreement with Pharmakon Advisors, LP to extend the maturity of the loan from November 2024 until March 2025, and to defer its principal payments until October 31, 2024.

Exhibit 99.1

Third Quarter Financial Results

Total Revenues: Total revenues were $42.0 million for the third quarter of 2023, compared to $48.7 million for the third quarter of 2022. The decrease is primarily due to a decrease in license, collaboration and other revenue.

Net Product Revenues: Net product revenues were $40.1 million for the third quarter of 2023, compared to $42.0 million for the third quarter of 2022. The decrease was primarily due to a reduction in volume and the impact of shifting payor mix, partially caused by contracting dynamics and a decline in the phosphate binder market. The decline was partially offset by price increases in January 2023 and July 2023.

License, Collaboration and Other Revenues: License, collaboration and other revenues were $1.9 million for the third quarter of 2023, compared to $6.7 million for the third quarter of 2022. The decrease is primarily due to the transfer and assignment of a supply agreement to Akebia's collaboration partner.

Cost of Goods Sold (COGS): COGS was $18.0 million for the third quarter of 2023, compared to $38.3 million for the third quarter of 2022. COGS reflects the costs of Auryxia, including non-cash intangible amortization charge of $9.0 million per quarter through the fourth quarter of 2024 and third-party royalties. The decrease was primarily due to a reduction in a non-cash charge related to the prior liability for excess purchase commitments, a decrease in inventory write-downs and lower volume of sales resulting in reduced product costs.

Research and Development (R&D) Expenses: R&D expenses were $13.3 million for the third quarter of 2023, compared to $28.0 million for the third quarter of 2022. The decrease was primarily due to a reduction in spending for vadadustat development, including clinical trial costs, and curtailment of outsourced contract services.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses were $22.7 million for the third quarter of 2023, compared to $31.9 million for the third quarter of 2022. The decrease was primarily due to a reduction in headcount related costs, the benefits realized from the assignment of the Boston lease in May 2023 and a targeted cutback in Auryxia marketing and promotional expense which were offset by some one-time non-recurring expenses.

Net Loss: Net loss was $14.5 million for the third quarter of 2023, compared to net loss of $54.1 million for the third quarter of 2022.

Cash Position: Cash, cash equivalents and restricted cash as of September 30, 2023, totaled $48.2 million. Akebia expects its existing cash resources and cash from operations will be sufficient to fund its current operating plan for at least the next twelve months.

About Vadadustat
Vadadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor 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 not approved by the U.S. Food and Drug Administration. Vadadustat is approved in Europe, Australia and Taiwan for the treatment of symptomatic anemia due to CKD in adult patients on chronic maintenance dialysis. In Japan, vadadustat is approved as a treatment for anemia due to CKD in both dialysis-dependent and non-dialysis dependent adult patients.

For safety information, view the European Summary of Product Characteristics (SPC/SmPC) for Vafseo® (vadadustat) at https://ec.europa.eu/health/documents/community-register/2023/20230424158854/anx_158854_en.pdf, https://products.mhra.gov.uk/ and https://www.swissmedic.ch/swissmedic/en/home/humanarzneimittel/authorisations/swisspar.html and will be available via the Australian Therapeutic Goods Administration website here.

AURYXIA (ferric citrate) is contraindicated in patients with iron overload syndromes, e.g., hemochromatosis.


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.

Exhibit 99.1


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%).


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 Akebia Therapeutics at 1-844-445-3799.
