Vafseo is approved for the TDAPA effective January 1, 2025

The Centers for Medicare & Medicaid Services (CMS) approved Vafseo for the Transitional Drug Add-on Payment Adjustment (TDAPA) under the End-Stage Renal Disease (ESRD) Prospective Payment System (PPS).

About the TDAPA

  • Under the TDAPA, CMS adjusts the bundled payment to providers for dialysis services by adding an amount for the cost of certain new renal dialysis drugs and biological products used in dialysis services
  • The TDAPA adjustment applies for patients covered under the Medicare ESRD PPS and continues for 2 years until December 31, 2026
  • The TDAPA helps dialysis organizations integrate innovative therapies into their treatment protocols to allow adoption of these products

Post-TDAPA, Akebia is committed to competitive pricing to ensure access to Vafseo for patients in need.

Frequently asked questions

Get the answers you need to support your patients’ journey

What is Vafseo?

Vafseo is a hypoxia-inducible factor prolyl hydroxylase inhibitor, also known as a HIF-PHI, given once-daily by mouth, for adults with anemia due to CKD who have been receiving dialysis for at least 3 months.1

What is the mechanism of action (MOA) of Vafseo? OR How does Vafseo work?

Vafseo is a hypoxia-inducible factor prolyl hydroxylase inhibitor, also known as a HIF-PHI, that works with the body’s natural response to hypoxia to increase endogenous erythropoietin (EPO) production.1-4

Are there any contraindications for Vafseo?

Vafseo is contraindicated in patients with known hypersensitivity to Vafseo or any of its components, and in patients with uncontrolled hypertension.1

What is the boxed warning for Vafseo?

Vafseo has a boxed warning for increased risk of death, myocardial infarction (MI), venous thromboembolism, and thrombosis of vascular access.1

How often should Hemoglobin (Hb) be monitored with Vafseo?

Hemoglobin should be monitored every 2 weeks upon initiation of Vafseo and after each dose adjustment until stable, then at least monthly.1

Can I use Vafseo in my patients who are also taking statins?

Vafseo increases the exposure of certain statins, such as simvastatin and rosuvastatin, when co-administered. If Vafseo is prescribed for a patient who is currently taking a statin: The starting dose of simvastatin should be 5 mg/day and the maximum daily dose should not exceed 20 mg/day. The maximum daily dose of rosuvastatin is not recommended to exceed 5 mg.1

It looks like Hb drops in the initial weeks when transitioning patients on ESAs to Vafseo. Why does this happen?

In the Prevalent Dialysis Trial, the data show an initial transient decrease in mean Hb in the Vafseo arm during the correction/conversion phase. All patients were started on a standardized dose of 300 mg once daily, regardless of prior ESA dosage. In the trial, investigators could only titrate up every 4 weeks and in increments of 150 mg.1,5,6

Approximately 35% of patients experienced a decrease in Hb levels of 0.5 g/dL or more at week 4 in the Prevalent Dialysis Trial* - especially in those previously maintained on high doses of ESAs (≥300 U/kg/week of IV epoetin equivalent unit).5,6,†

The mean Hb for the study population began to rise by week 8.4,

By week 12, more than half of patients were taking 450 mg or 600 mg.6,,‡

It’s important to anticipate a potential dip, which may serve as an opportunity to review dosing and titration, consistent with the Vafseo Prescribing Information.

How do I know if Vafseo is covered for my patients?

Vafseo has been approved for the TDAPA January 1, 2025.


Akebia Therapeutics Inc. does not guarantee payment or coverage for any product or service. ​The provider should contact patients’ payers directly for any revised or additional requirements, information, or guidance.

Can I use Vafseo with erythropoietin stimulating agents (ESAs)?

Vafseo is not approved for use in combination with ESAs. No clinical trials have investigated the efficacy or safety of combining Vafseo with ESAs.1,4
