Akebia Announces Third Quarter 2014 Financial Results

-Advancing Toward Global Phase 3 Registration Studies in 2015 Following Positive Top-Line Results from Phase 2b Study of AKB-6548-

CAMBRIDGE, Mass.—(BUSINESS WIRE)— 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 financial results for the third quarter ended September 30, 2014.

“In recent months, we have made substantial progress with our development program for AKB-6548 in renal anemia, most significantly, reporting positive top-line data from our Phase 2b study in non-dialysis patients with chronic kidney disease, or CKD.  This result provides a clear path forward into Phase 3 registration studies next year,” stated John P. Butler, President and Chief Executive Officer of Akebia. “The findings from that study confirmed that our once-daily, oral therapy can safely and predictably increase and maintain hemoglobin levels in this very ill patient population, and reinforce our confidence in the candidate’s best-in-class potential.  We are in a strong financial position to advance our ongoing Phase 2 study for AKB-6548 in CKD patients undergoing dialysis and to launch our global registration program.  We look forward to discussing the Phase 2b study results with U.S. and European regulatory agencies in preparation for launching Phase 3 registration studies.”

Third Quarter and Recent Corporate Highlights

Third Quarter 2014 Financial Results

Akebia reported a net loss and a net loss applicable to common stockholders of $9.3 million, or ($0.47) per share, for the third quarter of 2014. Net loss applicable to common stockholders for the third quarter of 2013, which includes accretion on preferred stock of $2.7 million, was $6.5 million or ($11.92) per share. In connection with the closing of the Company’s initial public offering on March 25, 2014, all of the Company’s outstanding shares of preferred stock were converted into shares of common stock.

Research and development expenses were $6.6 million for the third quarter of 2014 compared to $3.2 million for the third quarter of 2013. The increase of $3.4 million in research and development expenses is primarily attributable to costs related to AKB-6548 including, costs related to Phase 2 clinical development of AKB-6548 and the manufacture of drug

substance and drug product.  Research and development costs were further increased by stock-based compensation, wage and personnel-related costs due to increased headcount and drug development costs for AKB-6899.  

General and administrative expenses were $2.9 million for the third quarter of 2014 compared to $0.8 million for the third quarter of 2013. The increase of $2.1 million in general and administrative expenses is primarily related to an increase in wage and personnel related costs due to increased headcount, increased professional fees and commercial planning costs as well as increased stock-based compensation expense of $0.5 million.

The increased stock-based compensation expense in both research and development expenses and general and administrative expenses is primarily a result of an increase in the value of the Company’s common stock due to the Company’s initial public offering.

The Company’s cash used in operations during the third quarter of 2014 was $5.6 million, an increase of $2.7 million from $2.9 million for the same period of 2013. The Company ended the third quarter of 2014 with cash, cash equivalents and short-term investments of $118.3 million and expects its existing cash resources to support operations through the first half of 2016.
