CAMBRIDGE, MA, USA I April 25, 2023 I Akebia Therapeutics®, Inc. (Nasdaq: AKBA) today announced that the European Commission (EC) has granted marketing authorisation for Vafseo™ (vadadustat), an oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor for the treatment of symptomatic anaemia associated with chronic kidney disease (CKD) in adults on chronic maintenance dialysis. The approval is applicable to all 27 European Union member states plus Iceland, Norway and Liechtenstein. Vadadustat is now approved in 32 countries.

“We’re extremely pleased the EC has approved Vafseo, an important milestone for Akebia but even more impactful for the hundreds of thousands of Europeans diagnosed with anaemia associated with CKD on dialysis,” said John P. Butler, Chief Executive Officer of Akebia. “We believe patients receiving chronic maintenance dialysis would benefit from additional therapeutic options. With approval, we’re eager to select a European partner who can quickly bring Vafseo to those patients.”

Anemia associated with CKD, common in patients on dialysis, is a debilitating condition which may be associated with many adverse clinical outcomes. Vafseo, approved in 150 mg, 300 mg and 450 mg film-coated tablets, provides a once-daily oral treatment option for dialysis dependent patients with symptomatic anaemia associated with CKD. Throughout Europe, more than 200,000 dialysis patients are currently treated for anemia associated with CKD.

The approval follows the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) positive opinion issued in February 2023 recommending the EC approve Vafseo. The approval is based on data from a comprehensive development program that included over 7,500 patients, including the global Phase 3 clinical program of vadadustat for the treatment of anemia due to CKD in adult patients on dialysis (INNO2VATE).

In the study of adult patients on dialysis, vadadustat achieved the primary and key secondary efficacy endpoint in each of the two INNO2VATE studies, demonstrating non-inferiority to darbepoetin alfa as measured by a mean change in hemoglobin (Hb) between baseline and the primary evaluation period (weeks 24 to 36) and secondary evaluation period (weeks 40 to 52). Vadadustat also achieved the primary safety endpoint of the INNO2VATE program, defined as non-inferiority of vadadustat versus darbepoetin alfa in time to first occurrence of major adverse cardiovascular events, which is the composite of all-cause mortality, non-fatal myocardial infarction, or non-fatal stroke across both INNO2VATE studies.

John Butler added, “We are grateful for the patients, physicians, investigators, and site coordinators who participated in our clinical trials that led to this important approval. I want to also express my deep appreciation for our team at Akebia as the approval is a culmination of years of work and a demonstration of their commitment to bettering the lives of people impacted by kidney disease.”

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. In April 2023, the European Commission granted marketing authorization for vadadustat for the treatment of symptomatic anaemia associated with chronic kidney disease in adults 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.
