CMS Grants TDAPA Reimbursement for Vafseo® (vadadustat) beginning January 1, 2025

Designed to help dialysis organizations incorporate new treatments into their practices, TDAPA provides two years of reimbursement in addition to the ESRD bundled rate

A HCPCS code has also been assigned to Vafseo to facilitate reimbursement at dialysis organizations

CAMBRIDGE, Mass., Oct. 10, 2024 /PRNewswire/ -- Akebia Therapeutics^®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today announced that the Center for Medicare & Medicaid Services (CMS) has determined that Vafseo^® (vadadustat) meets the criteria for the Transitional Drug Add-On Payment Adjustment (TDAPA) in the anemia management end-stage renal disease (ESRD) prospective payment system functional category, beginning on January 1, 2025. In March 2024, Vafseo was approved by the U.S. Food and Drug Administration for the treatment of anemia due to chronic kidney disease in adults who have been receiving dialysis for at least three months, and the product is expected to be available in the market in January 2025. The TDAPA program provides two years of reimbursement for Vafseo in addition to the ESRD bundled rate to dialysis organizations.

Additionally, Akebia received a Level II Healthcare Common Procedure Coding System (HCPCS) code for Vafseo which will be used for billing for the product by dialysis organizations for Medicare enrollees. Within the next several weeks, CMS is expected to issue a Medicare Claims Processing Change Request that will give further billing guidance to dialysis organizations to obtain the separate TDAPA payment for the next two years under Medicare.

"We recognize the important benefit of TDAPA to support dialysis organizations' efforts to bring innovation to patients and incorporate new treatments into their practices," said Nicholas Grund, Chief Commercial Officer of Akebia. "The TDAPA status granted by CMS and issuance of a billing code are the latest milestones marking progress in the Vafseo commercial launch. We continue to actively engage dialysis organizations on the contracting process to facilitate access to Vafseo and look forward to further interacting with nephrologists and healthcare providers at the upcoming American Society of Nephrology conference, as we continue to build interest in Vafseo with a goal to drive usage and demand."

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.
