Akebia Announces Positive Top-Line Results from its Phase 2b Study of
AKB-6548 in Non-Dialysis Patients with Anemia Related to
Chronic Kidney Disease
Study Meets Primary Endpoint
Company Plans to Initiate Global Phase 3 Registration Studies in 2015
Conference Call at 8:30 AM Eastern Time Today
Cambridge, Mass. Oct. 27, 2014 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 positive top-line results from its Phase 2b placebo-controlled trial of AKB-6548 in non-dialysis patients with anemia related to chronic kidney disease (CKD). The study achieved its primary endpoint and AKB-6548 was generally well tolerated, confirming that the once-daily, oral therapy can successfully increase and maintain hemoglobin (HGB) levels.
The 20-week study enrolled 209 patients, who were randomized 2:1 to active treatment or placebo. The results showed that 54.9 percent of patients who received AKB-6548 met the primary endpoint versus 10.3 percent in the placebo group (p<0.0001). The primary endpoint was defined as achieving or maintaining a mean HGB ³ 11.0 g/dL or increasing HGB by ³ 1.2 g/dL above the pre-treatment value as measured by the mean HGB value at weeks 19 and 20.
The study also was designed to evaluate the ability of the dose titration algorithm to minimize HGB excursions ³ 13.0 g/dL. Only six patients (4.4 percent) treated with AKB-6548 experienced an excursion above this threshold. This result supports the adaptive dosing approach used in the study, which enabled robust HGB increases while minimizing excursions.
These Phase 2b results are impressive, demonstrating a sustained effect on hemoglobin throughout the twenty weeks of treatment, said Brad Maroni, M.D., Senior Vice President and Chief Medical Officer at Akebia. The challenges associated with current treatment options are well documented. The data underscore the potential of AKB-6548 to effectively raise and maintain hemoglobin levels in a safe, predictable and controlled manner.
AKB-6548 was generally well tolerated. Treatment-emergent adverse events (TEAEs) with AKB-6548 were consistent with those reported in past studies and were well balanced overall between the active and placebo treatment groups (74.6 percent and 73.6 percent, respectively). There was a higher incidence of serious adverse events (SAEs) reported in the active treatment group versus the placebo group (23.9 percent and 15.3 percent, respectively), the most common being renal-related. Of the 49 SAEs reported in the active treatment group, one was considered probably related to active treatment and two were considered possibly related, including one death. There were two additional deaths in the treatment group, neither of which was considered drug-related.
Patients at this advanced stage of CKD have many associated comorbidities and are progressing toward end stage renal disease and dialysis. The overall profile of study participants was consistent with that seen in the general population in the later stages of CKD.
There is a clear need for new treatment options for patients with renal anemia, said Steve Fishbane, M.D., Chief of Nephrology and Vice President of North Shore-Long Island Jewish Health System, Inc. These exciting results illustrate the therapeutic potential of AKB-6548 to address this unmet need, and I look forward to Akebias initiation of Phase 3 studies.
We are extremely pleased with the results of our Phase 2b study. This marks a very important milestone for Akebia and sets a clear path forward for a global Phase 3 program in renal anemia, said John P. Butler, President and Chief Executive Officer of Akebia. The strength of these data reinforces the best-in-class potential of AKB-6548 in anemia related to CKD and brings us a significant step closer to achieving our goal of bringing innovative therapies to renal patients who are in need of new treatment options. We look forward to discussing these data with U.S. and European regulatory agencies in preparation for launching Phase 3 registration studies next year.
Complete efficacy and safety data from this Phase 2b study will be presented at an upcoming medical meeting. Akebia is also evaluating AKB-6548 in a Phase 2 clinical study for the treatment of dialysis patients with anemia related to CKD. Results from that study are expected in the third quarter of 2015.
About AKB-6548 Phase 2b Study Design
The randomized, double-blind, placebo-controlled study evaluated the HGB response to orally administered AKB-6548, compared to baseline and to placebo treated subjects, in non-dialysis subjects with CKD stages 3, 4 and 5 dosed for 20 weeks. Secondary objectives were to evaluate the hematologic pharmacodynamic response, safety, and tolerability of orally administered AKB-6548. The study enrolled 209 non-dialysis patients with CKD stages 3, 4 and 5, who were randomized 2:1 to receive AKB-6548 or placebo. Patients initiated treatment with either 450 mg of AKB-6548 or placebo, administered once daily for 20 weeks. The dose was adjusted in accordance with the patients hemoglobin response based on the AKB-6548 dose titration algorithm. Patients were assigned to one of three study groups: recombinant erythropoietin stimulating agents (rESAs) treatment naïve, rESAs previously treated or rESAs actively treated.

AKB-6548 is a once-daily, oral therapy currently in development for the treatment of anemia related to CKD. AKB-6548 is designed to stabilize HIF, a transcription factor that regulates the expression of genes involved with red blood cell (RBC) production in response to changes in oxygen levels, by inhibiting the hypoxia-inducible factor prolyl hydroxylase (HIF-PH) enzyme. AKB-6548 exploits the same mechanism of action used by the body to naturally adapt to lower oxygen availability associated with a moderate increase in altitude. At higher altitudes, the body responds to lower oxygen availability with increased production of HIF, which coordinates the interdependent processes of iron mobilization and erythropoietin (EPO) production to increase RBC production and, ultimately, improve oxygen delivery.
As a HIF stabilizer with best-in-class potential, AKB-6548 may raise hemoglobin levels and RBC count predictably and sustainably, with a positive safety profile and a dosing regimen that allows for a gradual and controlled titration. Furthermore, AKB-6548 may improve iron mobilization, potentially eliminating intravenous iron administration and reducing the overall need for iron supplementation.
About Anemia Related to CKD
Approximately 30 million people in the United States have CKD, with an estimated 1.8 million of these patients suffering from anemia. Anemia results from the bodys inability to coordinate RBC production in response to lower oxygen levels due to the progressive loss of kidney function, which occurs in patients with CKD. Left untreated, anemia significantly accelerates patients overall deterioration of health with increased morbidity and mortality. Renal anemia is currently treated with injectable rESAs, which are associated with inconsistent hemoglobin responses and well-documented safety risks.
