Akebia to host Conference Call at 8:00 a.m. ET on Monday, November 10, 2025

CAMBRIDGE, Mass., Nov. 10, 2025 (GLOBE NEWSWIRE) -- 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, 2025 and recent business highlights.

"Through the quarter we've continued to make progress against our goal to make Vafseo standard of care for the treatment of anemia for patients on dialysis and capitalize on nephrologists' strong desire to prescribe Vafseo," said John P. Butler, Chief Executive Officer of Akebia. "These efforts include generating incremental data, like the data Dr. Glenn Chertow presented last week at ASN Kidney Week, further informing physicians about potential additional benefits of the product, and enabling increased patient access to Vafseo. To that end, we expect to close the year with four times the prescribing access to Vafseo as compared to the end of Q3, which we believe will accelerate broader uptake and growth in 2026."

Driving Vafseo Toward Our Goal to Become Standard of Care for Patients on Dialysis

• Vafseo^® (vadadustat) net product revenue in Q3 2025 totaled $14.3 million. The vast majority of Vafseo revenues were derived from US Renal Care (USRC) and since launch more than 85% of all USRC physicians have written a prescription. Total number of prescribers in Q3 was approximately 725 and the average number of prescriptions written per prescriber was approximately 12.7. More than 85% of prescriptions in Q3 were refill prescriptions. The average dose of refills increased by 5% over Q2.
• On August 18, DaVita, Inc. initiated an operational pilot at over 100 dialysis clinics. Akebia expects the pilot to complete in November at which point Vafseo is expected to be widely available to DaVita patients.
• In mid-August, Innovative Renal Care implemented a standardized treatment protocol for Vafseo across its approximately 230 dialysis centers. Seven additional independent and small dialysis providers also operationalized protocols in September, increasing total prescribing access across our customer base by the end of Q3 to 60,000 patients. We continue to expect this number to grow to 275,000 patients by the end of the year.
• At the recent American Society of Nephrology (ASN) Kidney Week 2025, Dr. Glenn M. Chertow presented a post-hoc analysis of data from the INNO2VATE trials comparing dialysis patients taking vadadustat or darbepoetin alfa for CKD-related anemia. The data demonstrated statistically significant more favorable outcomes in the composite of all-cause mortality and hospitalization in patients treated with vadadustat compared to patients in the ESA control group.
• At ASN Kidney Week, Akebia and partners presented posters on trial design for VOICE and VOCAL, clinical trials studying Vafseo three times weekly dosing, being conducted by USRC and by Akebia at DaVita, respectively. The VOICE trial is fully enrolled, and VOCAL enrollment is progressing well.
  
  

Regulatory Update

As previously announced, Akebia recently completed a Type C meeting with the U.S. Food and Drug Administration (FDA) and did not achieve alignment on Akebia's proposed path forward for a Phase 3 clinical trial in non-dialysis patients. Akebia does not plan to initiate the VALOR clinical trial and therefore does not expect to pursue a broad label for Vafseo for CKD non-dialysis dependent patients.

Financial Results

• Revenues: Total revenues increased to $58.8 million in the third quarter of 2025 compared to $37.4 million in the third quarter of 2024, driven by sales of Vafseo, which was launched in the U.S. in January 2025, and an increase in Auryxia® sales.
  • Vafseo net product revenues were $14.3 million in the third quarter of 2025.
  • Auryxia net product revenues were $42.5 million in the third quarter of 2025 as compared to $35.6 million in the third quarter of 2024. Though loss of exclusivity occurred on March 20, 2025, to date no Abbreviated New Drug Application has been approved for Auryxia, and there is only one authorized generic for Auryxia sold by Akebia's distributor.
  • License, collaboration and other revenues were $2.0 million in the third quarter of 2025 as compared to $1.8 million in the third quarter of 2024.
• Cost of Goods Sold: Cost of goods sold was $9.4 million in the third quarter of 2025 as compared to $14.2 million in the third quarter of 2024. Akebia carried a non-cash intangible amortization charge of $9.0 million per quarter through the fourth quarter of 2024. Of note, Vafseo-related cost of goods sold in the quarter was derived from pre-launch inventory, which does not include the full cost of manufacturing as a portion of those inventory-related expenses were recorded as research and development expenses in the period incurred prior to Vafseo's approval in the U.S.
• Research & Development Expenses: Research and development expenses were $14.9 million in the third quarter of 2025 as compared to $8.5 million in the third quarter of 2024. The increase was primarily driven by increased clinical trial activities related to Vafseo and higher headcount related costs.
• Selling, General & Administrative Expenses: Selling, general and administrative expenses were $29.1 million in the third quarter of 2025 as compared to $26.5 million in the third quarter of 2024. The increase was largely due to higher marketing costs in connection with the Vafseo U.S. launch and increased headcount-related costs.
• Net Income (Loss): Net income was $0.5 million in the third quarter of 2025 compared to a net loss of $20.0 million in the third quarter of 2024. The increase in net income was driven by the increase in net product revenues, which was partially offset by higher operating expenses.

• Cash Position: Cash and cash equivalents as of September 30, 2025 were approximately $166.4 million. Akebia believes it is financed to achieve profitability based on its current operating plan, which includes advancing its existing programs.

About Vafseo^® (vadadustat) tablets

Vafseo^® (vadadustat) tablets is a once-daily oral hypoxia-inducible factor prolyl hydroxylase inhibitor that activates the physiologic response to hypoxia to stimulate endogenous production of erythropoietin, increasing hemoglobin and red blood cell production to manage anemia. Vafseo is approved for use in 37 countries.

INDICATION

VAFSEO is indicated for the treatment of anemia due to chronic kidney disease (CKD) in adults who have been receiving dialysis for at least three months.

Limitations of Use

• VAFSEO has not been shown to improve quality of life, fatigue, or patient well-being.
• VAFSEO is not indicated for use:
  • As a substitute for red blood cell transfusions in patients who require immediate correction of anemia.
  • In patients with anemia due to CKD not on dialysis.

IMPORTANT SAFETY INFORMATION about VAFSEO (vadadustat) tablets

WARNING: INCREASED RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, and THROMBOSIS OF VASCULAR ACCESS.

VAFSEO increases the risk of thrombotic vascular events, including major adverse cardiovascular events (MACE).

Targeting a hemoglobin level greater than 11 g/dL is expected to further increase the risk of death and arterial and venous thrombotic events, as occurs with erythropoietin stimulating agents (ESAs), which also increase erythropoietin levels.

No trial has identified a hemoglobin target level, dose of VAFSEO, or dosing strategy that does not increase these risks.

Use the lowest dose of VAFSEO sufficient to reduce the need for red blood cell transfusions.

CONTRAINDICATIONS

• Known hypersensitivity to VAFSEO or any of its components
• Uncontrolled hypertension

WARNINGS AND PRECAUTIONS

• Increased Risk of Death, Myocardial Infarction (MI), Stroke, Venous Thromboembolism, and Thrombosis of Vascular Access
  
  A rise in hemoglobin (Hb) levels greater than 1 g/dL over 2 weeks can increase these risks. Avoid in patients with a history of MI, cerebrovascular event, or acute coronary syndrome within the 3 months prior to starting VAFSEO. Targeting a Hb level of greater than 11 g/dL is expected to further increase the risk of death and arterial and venous thrombotic events. Use the lowest effective dose to reduce the need for red blood cell (RBC) transfusions. Adhere to dosing and Hb monitoring recommendations to avoid excessive erythropoiesis.

• Hepatotoxicity
  
  Hepatocellular injury attributed to VAFSEO was reported in less than 1% of patients, including one severe case with jaundice. Elevated serum ALT, AST, and bilirubin levels were observed in 1.8%, 1.8%, and 0.3% of CKD patients treated with VAFSEO, respectively. Measure ALT, AST, and bilirubin before treatment and monthly for the first 6 months, then as clinically indicated. Discontinue VAFSEO if ALT or AST is persistently elevated or accompanied by elevated bilirubin. Not recommended in patients with cirrhosis or active, acute liver disease.

• Hypertension
  
  Worsening of hypertension was reported in 14% of VAFSEO and 17% of darbepoetin alfa patients. Serious worsening of hypertension was reported in 2.7% of VAFSEO and 3% of darbepoetin alfa patients. Cases of hypertensive crisis, including hypertensive encephalopathy  and seizures, have also been reported in patients receiving VAFSEO. Monitor blood pressure. Adjust anti-hypertensive therapy as needed.

• Seizures
  
  Seizures occurred in 1.6% of VAFSEO and 1.6% of darbepoetin alfa patients. Monitor for new-onset seizures, premonitory symptoms, or change in seizure frequency.

• Gastrointestinal (GI) Erosion
  
  Gastric or esophageal erosions occurred in 6.4% of VAFSEO and 5.3% of darbepoetin alfa patients. Serious GI erosions, including GI bleeding and the need for RBC transfusions, were reported in 3.4% of VAFSEO and 3.3% of darbepoetin alfa patients. Consider this risk in patients at increased risk of GI erosion. Advise patients about signs of erosions and GI bleeding and urge them to seek prompt medical care if present.

• Serious Adverse Reactions in Patients with Anemia Due to CKD and Not on Dialysis
  
  The safety of VAFSEO has not been established for the treatment of anemia due to CKD in adults not on dialysis and its use is not recommended in this setting. In large clinical trials in adults with anemia of CKD who were not on dialysis, an increased risk of mortality, stroke, MI, serious acute kidney injury, serious hepatic injury, and serious GI erosions was observed in patients treated with VAFSEO compared to darbepoetin alfa.

• Malignancy
  
  VAFSEO has not been studied and is not recommended in patients with active malignancies. Malignancies were observed in 2.2% of VAFSEO and 3.0% of darbepoetin alfa patients. No evidence of increased carcinogenicity was observed in animal studies.

ADVERSE REACTIONS

• The most common adverse reactions (occurring at ≥ 10%) were hypertension and diarrhea.
  
  

DRUG INTERACTIONS

• Iron supplements and iron-containing phosphate binders: Administer VAFSEO at least 1 hour before products containing iron.
• Non-iron-containing phosphate binders: Administer VAFSEO at least 1 hour before or 2 hours after non-iron-containing phosphate binders.
• BCRP substrates: Monitor for signs of substrate adverse reactions and consider dose reduction.
• Statins: Monitor for statin-related adverse reactions. Limit the daily dose of simvastatin to 20 mg and rosuvastatin to 5 mg.

USE IN SPECIFIC POPULATIONS

• Pregnancy: May cause fetal harm.
• Lactation: Breastfeeding not recommended until two days after the final dose.
• Hepatic Impairment: Not recommended in patients with cirrhosis or active, acute liver disease.
