FDA Approves Vadadustat for Treatment of Anemia due to CKD in Patients on Dialysis


The FDA approved the oral medication to treat anemia in adult patients with chronic kidney disease on dialysis for at least 3 months.

Akebia Therapeutics announced that vadadustat (Vafseo) received FDA approval for adult patients with chronic kidney disease (CKD) experiencing anemia after at least 3 months of dialysis treatment. The approval follows launches of the drug in more than 30 other countries. This announcement makes the US the 37th country to approve vadadustat.

Anemia is experienced by an estimated 500 000 adult patients in the US who have been treated with dialysis. The deficit of red blood cells reduces tissue oxygenation. Anemia is also commonly seen among individuals with CKD as renal production of erythropoietin is reduced.

Fatigue, dizziness, shortness of breath, and cognitive dysfunction are common symptoms of anemia. These outcomes, in conjunction with CKD, can decrease a patient’s quality of life. Without appropriate treatment for anemia associated with CKD, health decline can be rapid and mortality rate increases.

Patients with CKD often struggle with managing uncontrollable anemia, which can incur health care costs and overall negative impacts on their daily life. Prior to vadadustat, treatment for anemia was the injection of erythropoiesis-stimulating agents, mainly administered at dialysis centers.

John P. Butler, CEO of Akebia, described vadadustat in a 2020 interview with The American Journal of Managed Care® as “a HIF-PHI, which is a hypoxia-inducible [factor] prolyl hydroxylase inhibitor and basically, its mechanism of action is the same as increasing altitude.”2 Vadadustat, an oral medication prescribed to patients once a day, enables a physiologic response to hypoxia for the stimulation of endogenous production of erythropoietin to manage anemia.

Butler continued to explain, “Vadadustat basically works by inhibiting the inhibitor, inhibiting the pro hydroxylase which allows HIF to stabilize, which allows the body to make red blood cells.”2

The approval was based on efficacy and safety data from the INNO2VATE program, published in the New England Journal of Medicine in 2021.3 Two phase 3 trials found that vadadustat was not inferior to darbapoetin alfa with respect to correction and maintenance of hemoglobin concentrations, as well as cardiovascular safety. The approval also took into account postmarketing safety data from Japan after the drug's launch there.1

Akebia plans to partner with CSL Vifor, a pharmaceutical company with therapies in the dialysis field, to commercialize vadadustat throughout the US and potentially become a new oral standard of care for adult patients undergoing dialysis.1

"Patients receiving maintenance dialysis would benefit from additional therapeutic options that can effectively increase and maintain hemoglobin concentrations within guideline-recommended target ranges," Glenn M. Chertow, MD, MPH, professor of medicine in the Division of Nephrology at Stanford University and cochair of the independent Executive Steering Committee for the PRO2TECT and INNO2VATE clinical trial programs, said in Akebia’s news release.1
