New Commercial Supply Contracts for Vafseo® (vadadustat) secured, bringing availability and dialysis organization coverage to nearly 100% of patients on dialysis in U.S. 

Vafseo tablets now shipping in the U.S. 

Plan to start Phase 3 trial in mid-2025 to potentially expand Vafseo label to include treatment of late-stage non-dialysis CKD patients

Company to discuss business updates at 43^rd Annual J.P. Morgan Healthcare Conference

CAMBRIDGE, Mass., Jan. 13, 2025 /PRNewswire/ -- Akebia Therapeutics^®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today announced multiple positive business updates. As of January, Vafseo® (vadadustat) tablets are available in the U.S. for adult patients with anemia due to chronic kidney disease (CKD) on dialysis for at least three months, and shipment of product to dialysis centers has commenced. In addition, Akebia recently signed a Vafseo commercial supply agreement with a leading dialysis organization. Akebia now has contracts in place with dialysis organizations caring for nearly 100% of dialysis patients in the U.S. As previously announced, Vafseo qualifies for the Transitional Drug Add-On Payment Adjustment (TDAPA) reimbursement as directed by the Centers for Medicare & Medicaid Services (CMS), and CMS has published billing guidance and reimbursement rates.

Akebia also announced its plans to begin a Phase 3 trial for the use of vadadustat in treating anemia in late-stage CKD patients who are not on dialysis. Akebia received feedback from the U.S. Food and Drug Administration (FDA) on its protocol submission for a label expansion study and is incorporating feedback as appropriate. Akebia expects to begin the trial in mid-2025.

"We believe Akebia is entering a transformational year with the U.S. market availability of Vafseo, which we believe could become a new standard of care for patients with CKD," said John P. Butler, Chief Executive Officer of Akebia. "During 2025 our commercial organization will remain focused on executing the U.S. launch of Vafseo, while our development team pursues label expansion of Vafseo into the non-dialysis population, which represents a potential multiple billion-dollar market opportunity in the U.S. We believe our commercial products and pipeline have the potential to generate significant shareholder value as Akebia strengthens its leadership position in the treatment of kidney disease and the hypoxia-inducible factor (HIF) space."

Vafseo Commercial Update:

• Vafseo began shipping to dialysis centers and authorized distributors on January 9, 2025.
• Akebia has secured broad access for Vafseo as the company has now entered into commercial supply agreements with dialysis organizations treating nearly 100% of patients on dialysis in the U.S., including recently signing agreements with a leading dialysis organization and a mid-size dialysis provider.
• Akebia market research suggests 99% of nephrologists would consider prescribing Vafseo to certain eligible patients, with 75% intending to do so by 6 months after product availability.
• In December 2024, Akebia announced that U.S. Renal Care enrolled the first patients in the VOICE collaborative clinical trial of Vafseo. U.S. Renal Care has now enrolled more than 650 patients in the trial.

Planned Phase 3 Trial of Vadadustat in U.S. Non-Dialysis CKD Patients:

• In March 2024, the FDA approved Vafseo for the treatment of anemia due to chronic kidney disease in adults who have been receiving dialysis for at least three months.
• The FDA acknowledged an unmet need for safer and orally available therapies to treat anemia due to CKD in certain non-dialysis patients.
• Akebia has since engaged with the FDA on potentially expanding vadadustat treatment to this patient population and has received feedback on a protocol submitted for a Phase 3 cardiovascular outcome study of approximately 1,500 U.S. subjects with late-stage CKD anemia not on dialysis, which is expected to begin in mid-2025.
• Akebia plans to request a Type C meeting with the FDA to continue to discuss the statistical analysis plan and regulatory path.
• Akebia expects its existing cash resources and cash from operations will be sufficient to fund its current operating plan, including the U.S. Vafseo launch and planned pipeline advancement, for at least two years.

Presentation at 43^rd J.P. Morgan Healthcare Conference
John Butler, Chief Executive Officer, will present on Thursday, January 16^th, 2025 at 7:30 a.m. PST. A webcast of the presentation can be accessed through the "Investors" section of Akebia's website for 30 days following the conference.

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

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.
