Plain-language summary
This study is being conducted to demonstrate the effect of Auryxia, when used as the primary phosphate lowering therapy, on the overall cumulative use of erythropoiesis-stimulating agent and intravenous iron as well as on the laboratory parameters indicative of phosphate and anemia management.

Inclusion criteria
. Adult participants greater or equal to 18 years old.
. Diagnosis of end-stage kidney disease and receiving maintenance dialysis (in-center, home hemodialysis or peritoneal dialysis) for greater or equal to 12 weeks prior to randomization.
. Most recent transferrin saturation less than or equal to 50 percent
. Most recent serum phosphate is greater or equal to 3.0 milligrams per deciliter
. Receiving treatment for greater or equal to 8 weeks prior to screening with non-Auryxia phosphate lowering therapy. No requirement for stable dosing within this time frame.
. Receiving treatment for greater or equal to 8 weeks prior to screening with erythropoiesis-stimulating agent (any dose, any type). No requirement for stable dosing within this time frame.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Difference in mean dose of erythropoiesis-stimulating agent (standardized Units per month) between Auryxia and standard of care treatment groups
Timeframe: Baseline period (Month -3 to Day 1) to months 4to 6 (efficacy evaluation period)
2
Difference in mean dose of intravenous iron (milligram per month) between Auryxia and standard of care treatment groups.
Timeframe: Baseline period (Month -3 to Day 1) to months 4 to6 (efficacy evaluation period)
. Understands the procedures and requirements of the study and provides written informed consent and authorization for protected health information disclosure.
Exclusion criteria
. A known allergy or intolerance to Auryxia or any of its constituents.
. Hypersensitivity reaction to previous oral iron therapy.
. History of hemochromatosis or other iron overload syndrome.
. Active malignancy requiring current treatment except for non-melanoma skin cancer regardless of treatment.
. Active drug or alcohol dependence or abuse (excluding tobacco use or medicinal or recreational marijuana) within the 12 months prior to Screening or evidence of such abuse (in the opinion of the Investigator).
. Limited life expectancy (less than 6 months), (in the opinion of the Investigator).
. Scheduled organ transplant and participants on the kidney transplant wait-list who are expected to receive a transplant within 6 months of screening. Being active on transplant list is not an exclusion. Previous kidney transplant is not an exclusion.
. Unable to comply with study requirements or in the opinion of the Investigator not clinically stable to participate in the study.
