CAMBRIDGE, Mass., Sept. 28, 2023 /PRNewswire/ -- Akebia Therapeutics®, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, today announced it has resubmitted its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for vadadustat, Akebia's investigational oral hypoxia-inducible factor prolyl hydroxylase inhibitor, for the treatment of anemia due to chronic kidney disease (CKD) in adult patients on dialysis. Vadadustat is currently approved for use in 35 countries.

"We are pleased to have resubmitted the NDA for vadadustat following multiple discussions with the FDA and clear direction from the agency, a significant milestone that reflects our team's commitment to patients and conviction in the benefit we believe vadadustat can deliver to patients on dialysis," said John P. Butler, Chief Executive Officer of Akebia. "Our team assembled a comprehensive resubmission, which now includes post-marketing safety data from tens of thousands of patients in Japan where vadadustat is approved and has been in market for more than three years. We look forward to working with the FDA during the review process and are eager to offer a new oral therapeutic to patients if approved."

Based on standard NDA resubmission review timelines, a letter from the FDA acknowledging that the resubmission is complete, classifying the resubmission, and setting the PDUFA date is expected in 30 days. Akebia expects the FDA to set a PDUFA date of six months from the date of submission.

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. Vadadustat is approved in 35 countries, including Europe and Australia for the treatment of symptomatic anemia due to CKD in adult patients on chronic maintenance dialysis and Japan as a treatment for anemia due to CKD in both dialysis-dependent and non-dialysis dependent adult patients.
