Akebia Therapeutics Names Rita Jain, M.D. as Chief Medical Officer

CAMBRIDGE, Mass. May 25, 2017 Akebia Therapeutics, Inc. (NASDAQ:AKBA), a biopharmaceutical company focused on

delivering innovative therapies to patients with kidney disease through the biology of hypoxia-inducible factor (HIF), today announced the appointment of Rita Jain, M.D. as Senior Vice President and Chief Medical Officer. Dr. Jain will be

responsible for leading the clinical development of the Company s HIF pipeline, including the global Phase 3 development program for vadadustat, an oral HIF stabilizer in development for the treatment of anemia related to chronic kidney

disease. Dr. Jain succeeds Brad Maroni, M.D. who will remain at Akebia as a medical advisor.

Rita has more than 20 years of drug development

experience, and having directed multiple registration trials as well as a large cardiovascular patient outcomes-driven trial, her expertise will be particularly relevant to her role at Akebia, said John P. Butler, President and Chief Executive

Officer of Akebia. Her experience working with key opinion leaders and collaborators will be important as we complete clinical development of vadadustat, prepare for regulatory submissions and set the stage for commercialization. I d like

to thank Brad for his many contributions to the development of vadadustat and our pipeline, and we are pleased that he will be an advisor to Akebia.

Dr. Jain joins Akebia from AbbVie where she most recently was the Vice President of Men s and Women s Health and Metabolic Development. During

her time at AbbVie and Abbott she oversaw the development of more than 15 new chemical entities and marketed products. She has also held leadership roles at Pharmacia Corp., as well as a faculty position at the North Shore University Hospital where

she was the Director of the Program in Novel Therapeutics. Dr. Jain earned her M.D. at the State University of New York at Stony Brook School of Medicine and her B.S. from LIU/C.W. Post.

I am excited to join Akebia at a pivotal time in the global Phase 3 development program for vadadustat, said Dr. Jain. The strong

foundation of clinical data from 15 trials of vadadustat gives me great confidence in our Phase 3 program, and underscores the potential of vadadustat to help patients living with anemia related to chronic kidney disease. I look forward to working

with my colleagues at Akebia, investigators and the regulatory authorities to bring this innovative treatment to patients.

Anemia results from the body s inability to coordinate red blood cell production in response to lower oxygen levels due to

the progressive loss of kidney function with inadequate erythropoietin production. Left untreated, anemia significantly accelerates patients overall deterioration of health with increased morbidity and mortality. Anemia is currently treated

with injectable recombinant erythropoiesis stimulating agents, which are associated with inconsistent hemoglobin responses and well-documented safety risks. The prevalence of anemia increases with the severity of CKD and is higher in people

with CKD who are over age 60.
