Akebia Therapeutics Receives Complete Response Letter from the FDA for Vadadustat for the Treatment of Anemia due to Chronic Kidney Disease in Adult Patients

Company to host conference call on Wednesday, March 30, 2022 at 6:00 p.m. ET

CAMBRIDGE, Mass., March 30, 2022 /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 U.S. Food and Drug Administration (FDA) has issued a complete response letter (CRL) to Akebia's New Drug Application (NDA) for vadadustat, an investigational oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor under review for the treatment of anemia due to chronic kidney disease (CKD). The FDA issues a CRL to indicate that the review cycle for an application is complete and that the application is not ready for approval in its present form.

The FDA concluded that the data in the NDA do not support a favorable benefit-risk assessment of vadadustat for dialysis and non-dialysis patients. The FDA expressed safety concerns noting failure to meet non-inferiority in MACE in the non-dialysis patient population, the increased risk of thromboembolic events, driven by vascular access thrombosis in dialysis patients, and the risk of drug-induced liver injury. The CRL stated that Akebia could explore ways to potentially demonstrate a favorable benefit-risk assessment through new clinical trials. Akebia will discuss the details of the CRL with its collaboration partners and request a meeting with the FDA.

"We are extremely disappointed to receive a CRL for vadadustat, a therapy that has the potential to help patients with anemia due to CKD. We continue to believe the data are supportive of a positive benefit-risk assessment of vadadustat for patients with anemia due to CKD, particularly in dialysis patients," said John P. Butler, Chief Executive Officer of Akebia. "Despite this setback, we continue to work toward our purpose to better the lives of people impacted by kidney disease." 

In October 2021, Akebia's collaboration partner, Otsuka Pharmaceutical Co., Ltd. (Otsuka), submitted an initial marketing authorization application (MAA) for vadadustat to the European Medicines Agency for vadadustat, for the treatment of anemia due to CKD in adults; the review is ongoing. In Japan, vadadustat is approved as a treatment for anemia due to CKD in both dialysis-dependent and non-dialysis dependent adult patients.

About Anemia due to Chronic Kidney Disease (CKD) 
Anemia is a condition in which a person lacks enough healthy red blood cells to carry adequate oxygen to the body's tissues. It commonly occurs in people with CKD because their kidneys do not produce enough erythropoietin (EPO), a hormone that helps regulate production of red blood cells. Anemia due to CKD can have a profound impact on a person's quality of life as it can cause fatigue, dizziness, shortness of breath and cognitive dysfunction. Left untreated, anemia leads to deterioration in health and is associated with increased morbidity and mortality in people with CKD.

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 an investigational new drug and is not approved by the U.S. Food and Drug Administration (FDA).  On March 29, 2022, the FDA issued a complete response letter to Akebia's New Drug Application for vadadustat for the treatment of anemia due to chronic kidney disease (CKD). Vadadustat is currently under review by the European Medicines Agency for the treatment of anemia due to CKD in adults.  In Japan, vadadustat is approved as a treatment for anemia due to CKD in both dialysis-dependent and non-dialysis dependent adult patients.
