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 the publication of positive results from a Phase 2a study of vadadustat, a once-daily oral HIF stabilizer in development for the treatment of anemia related to chronic kidney disease (CKD). The study demonstrated that vadadustat increased hemoglobin levels in a dose-dependent manner and improved iron mobilization in non-dialysis CKD patients when compared to placebo. The peer-reviewed paper, titled “Clinical Trial of Vadadustat in Patients with Anemia Secondary to Stage 3 or 4 Chronic Kidney Disease,” was published online by the American Journal of Nephrology. Vadadustat is currently being evaluated in a global Phase 3 clinical program in non-dialysis and dialysis patients with anemia related to CKD.
This multicenter, six-week, randomized, double-blind, placebo-controlled, dose-ranging Phase 2a trial evaluated the pharmacodynamic response, safety and tolerability of once-daily oral dose of vadadustat in non-dialysis patients with anemia related to CKD Stage 3 or 4. Ninety-three patients were randomized to one of five dose groups: 240, 370, 500, or 630 mg of once daily oral vadadustat or matching placebo for six weeks of treatment.
Findings from the study included:
- Vadadustat increased hemoglobin levels in patients across all treatment groups compared to placebo;
- Vadadustat improved iron mobilization compared to the placebo group, as measured by decreases in ferritin and hepcidin and increases in total iron binding capacity; and
- Safety findings were consistent with results of other studies of vadadustat and the proportion of patients with at least one treatment-emergent adverse event was similar between the vadadustat and placebo-treated groups, with no apparent dose-related effect.
“This Phase 2a publication further demonstrates the potential of vadadustat to set a new standard of care in renal anemia and provides a strong basis for our global Phase 3 program, which continues to enroll CKD patients in both the non-dialysis and dialysis dependent setting,” said Brad Maroni, M.D., Chief Medical Officer at Akebia.
About Vadadustat
Vadadustat is an oral hypoxia-inducible factor (HIF) stabilizer currently in Phase 3 development for the treatment of anemia related to chronic kidney disease. Vadadustat exploits the same mechanism of action used by the body to adapt naturally 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 production to increase red blood cell production and, ultimately, improve oxygen delivery.
About Anemia Associated with CKD
Approximately 30 million people in the U.S. have chronic kidney disease (CKD), with an estimated 1.8 million of these patients suffering from anemia. 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.
