CAMBRIDGE, Mass., Oct. 23, 2020 /PRNewswire/ — Akebia Therapeutics Inc. (Nasdaq: AKBA), at present introduced the presentation of scientific knowledge from its PRO2TECT international Section Three program that evaluated the efficacy and security of vadadustat, Akebia’s investigational oral hypoxia-inducible issue prolyl hydroxylase inhibitor (HIF-PHI), versus darbepoetin alfa for the remedy of anemia on account of persistent kidney illness (CKD) in grownup sufferers not on dialysis, at American Society of Nephrology Kidney Week 2020 Reimagined (ASN Kidney Week). As beforehand introduced, vadadustat achieved the first and key secondary efficacy endpoints in every of the 2 research in this system, however didn’t meet the first security endpoint. Newly introduced pre-specified regional analyses of the PRO2TECT program present vadadustat demonstrated no clinically significant improve in cardiovascular threat in comparison with darbepoetin alfa in analyses of MACE, expanded MACE and all-cause mortality in U.S. sufferers handled to a goal hemoglobin (Hb) vary of 10 to 11 g/dL, per U.S. remedy pointers.
“The PRO2TECT outcomes present that orally administered vadadustat achieved each main and secondary efficacy endpoints in sufferers not on dialysis with anemia related to CKD. The newly introduced analyses confirmed that there have been regional variations with respect to MACE, expanded MACE and all-cause mortality, per well-known, differing regional hemoglobin remedy goal pointers,” stated Glenn Chertow, M.D., M.P.H., Professor of Medication, Chief, Division of Nephrology at Stanford College, and Co-Chair of the unbiased Government Steering Committee for PRO2TECT and INNO2VATE. “The analyses additionally affirm there was no elevated cardiovascular threat related to vadadustat throughout the U.S. sufferers handled to a goal hemoglobin vary of 10 to 11 g/dL.”
The PRO2TECT knowledge are being introduced at present throughout a late-breaking oral presentation, titled “World Section Three Medical Trials of Vadadustat vs Darbepoetin Alfa for Remedy of Anemia in Sufferers with Non-Dialysis-Dependent Power Kidney Illness” (Summary FR-OR54) at ASN Kidney Week.

Outcomes from this program have been introduced at ASN Kidney Week in an oral presentation on October 22, 2020.
Highlights of the PRO2TECT ASN Kidney Week Presentation:
- As beforehand reported, vadadustat achieved the first and key secondary efficacy endpoints in every of the 2 PRO2TECT research, which demonstrated non-inferiority of vadadustat to darbepoetin alfa as measured by a imply change in Hb between baseline and the first analysis interval (weeks 24 to 36) and secondary analysis interval (weeks 40 to 52). Non-inferiority was achieved because the decrease certain of the 95% confidence interval for the between-group distinction of the imply Hb change didn’t fall beneath the pre-specified non-inferiority margin (-0.75 g/dL).
- As beforehand reported, vadadustat didn’t meet the first security endpoint of the PRO2TECT program outlined as non-inferiority of vadadustat versus darbepoetin alfa in time to first prevalence of main opposed cardiovascular occasions (MACE), which is the composite of all-cause mortality, non-fatal myocardial infarction (MI), or non-fatal stroke throughout each PRO2TECT research.
- The evaluation of the first security endpoint used a Cox regression mannequin that was pre-specified to be adjusted for sure variables, together with age dichotomized >65 and ≤65 years.
- So as to optimize the Cox mannequin used to investigate the first security endpoint and improve its statistical energy in regional subsets, age was rescaled from dichotomous to a steady variable.
- Within the optimized Cox mannequin, the hazard ratios (HR) have been attenuated and the boldness intervals (CI) have been narrowed.
- The PRO2TECT examine evaluation plan was prospectively designed to investigate the impact of regional variations, most notably, well-known variations in Hb remedy targets. Inside the examine, U.S. sufferers have been handled to a goal Hb vary of 10 to 11 g/dL and non-U.S. sufferers have been handled to a goal Hb vary of 10 to 12 g/dL.
- In a pre-specified regional evaluation utilizing age as a dichotomous variable, vadadustat was not related to a clinically significant improve in cardiovascular threat in comparison with darbepoetin alfa in U.S. sufferers handled to a goal Hb vary of 10 to 11 g/dL, with a MACE HR of 1.06 (0.87, 1.29). This was confirmed utilizing age as a steady variable as proven beneath.
- The incidence of remedy emergent opposed occasions throughout the ESA-untreated sufferers (Correction) examine within the vadadustat-treated sufferers was 90.9%, and 91.6% in darbepoetin alfa-treated sufferers. Throughout the examine, the commonest remedy emergent opposed occasions reported in vadadustat/darbepoetin alfa-treated sufferers have been end-stage renal illness (34.7%/ 35.2%), hypertension (17.7%/ 22.1.%), hyperkalemia (12.3.%/ 15.6%), urinary tract an infection (12.9%/ 12.0%), diarrhea (13.9%/ 10.0%), peripheral oedema (12.5%/ 10.5%), fall (9.6%/ 10%) and nausea (10%/ 8.2%). Critical remedy emergent opposed occasions have been 65.3% for vadadustat-treated sufferers and 64.5% for darbepoetin alfa-treated sufferers. The incidence of remedy emergent opposed occasions throughout the ESA-treated sufferers (Conversion) examine in vadadustat handled sufferers was 89.1% and 87.7% in darbepoetin alfa-treated sufferers. Throughout the examine, the commonest remedy emergent opposed occasions reported in vadadustat/darbepoetin alfa-treated sufferers have been end-stage renal illness (27.5%/ 28.4%), hypertension (14.4%/ 14.8%), urinary tract an infection (12.2%/ 14.5%), diarrhea (13.8.%/ 8.8.%), peripheral oedema (9.9%/ 10.1%) and pneumonia (10.0%/ 9.7%). Critical remedy emergent opposed occasions have been 58.5% for vadadustat-treated sufferers and 56.6% for darbepoetin alfa-treated sufferers.
“The newly introduced pre-specified analyses of PRO2TECT confirmed that vadadustat had no clinically significant improve in cardiovascular threat in U.S. sufferers not on dialysis handled to a goal hemoglobin vary of 10 to 11 g/dL, per U.S. remedy pointers. Upon submission of our NDA for vadadustat, we count on that the potential approval of vadadustat as a remedy for sufferers not on dialysis might be a assessment subject for the FDA, and we proceed to consider that these essential analyses, along with the totality of knowledge from our Section Three program, will inform that assessment,” stated John P. Butler, President and CEO of Akebia Therapeutics. “We stay assured that vadadustat has a simple path to potential approval for the remedy of sufferers on dialysis, globally.”

Each PRO2TECT research have been international, multicenter, open label (sponsor blind), active-controlled (darbepoetin alfa – an injectable erythropoiesis stimulating agent (ESA)), non-inferiority research. In each research, sufferers have been randomized 1:1 to obtain both vadadustat or darbepoetin alfa. Efficacy and security outcomes have been measured towards non-inferiority margins agreed upon with the FDA and the EMA.
About Anemia on account of Power Kidney Illness (CKD)
Anemia is a situation by which an individual lacks sufficient wholesome purple blood cells to hold enough oxygen to the physique’s tissues. It generally happens in individuals with CKD as a result of their kidneys don’t produce sufficient erythropoietin (EPO), a hormone that helps regulate manufacturing of purple blood cells. Anemia on account of CKD can have a profound affect on an individual’s high quality of life as it will possibly trigger fatigue, dizziness, shortness of breath and cognitive dysfunction. Left untreated, anemia results in deterioration in well being and is related to elevated morbidity and mortality in individuals with CKD.
Vadadustat is an oral hypoxia-inducible issue prolyl hydroxylase (HIF-PH) inhibitor designed to imitate the physiologic impact of altitude on oxygen availability. At increased altitudes, the physique responds to decrease oxygen availability with stabilization of hypoxia-inducible issue, which might result in elevated purple blood cell manufacturing and improved oxygen supply to tissues. Vadadustat is in international Section Three growth for the remedy of anemia on account of CKD and isn’t permitted by the U.S. Meals and Drug Administration (FDA) or any regulatory authority except for Japan’s Ministry of Well being, Labour and Welfare (MHLW). In Japan, vadadustat is permitted as a remedy for anemia on account of CKD in each dialysis-dependent and non-dialysis dependent grownup sufferers.
