Effect of Sodium Zirconium Cyclosilicate on Arrythmia-related Cardiovascular Outcomes in Participants on Chronic Hemodialysis With Recurrent Hyperkalemia (DIALIZE-Outcomes)
Stopped: The event rate observed in the study continued to be below primary assumptions, so that the completion of the study within a reasonable timeframe was deemed very unlikely.

Inclusion criteria
. Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol
. Provision of signed and dated, written ICF prior to any mandatory study specific procedures, sampling, and analyses
. Must be ≥ 18 years of age, at the time of signing the ICF.
. Receiving hemodialysis (or hemodiafiltration) 3 times a week for treatment of ESRD for ≥ 4 months before enrollment
. Must have hemodialysis access consisting of an arteriovenous fistula, arteriovenous graft, or tunneled (permanent) catheter which is expected to remain in place for the entire duration of the study
. At least 2 out of 3 pre-dialysis S K ≥ 5.5 mmol/L after the LIDI during screening
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
Incidence of the Composite of Cardiac Event Outcomes
Timeframe: From Randomization (Visit 4) up to week 129 (Randomized Study Intervention Phase)
. Negative pregnancy test for female participants of childbearing potential
. Female participants must be 1 year postmenopausal, surgically sterile, or using one highly effective form of birth control (defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly). They should have been stable on their chosen method of birth control for a minimum of 3 months before entering the study and willing to remain on the birth control until 12 weeks after the last dose
Exclusion criteria
. Pseudohyperkalemia secondary to hemolyzed blood specimen (this situation is not considered screening failure, sampling or full screening can be postponed to a later time as applicable)
. Presence of cardiac arrhythmias or conduction defects that require immediate treatment
. Participants who have a pacemaker or implantable cardiac defibrillator
. Any medical condition, including active, clinically significant infection or liver disease, that in the opinion of the investigator or sponsor may pose a safety risk to a participant in this study, confound safety or efficacy assessment and jeopardize the quality of the data, or interfere with study participation, or any other restrictions or contraindications in the local prescribing information for SZC
. History of QT prolongation associated with other medications that required discontinuation of that medication
. Congenital long QT syndrome
. QTcF \> 550 msec
. Atrial fibrillation requiring immediate/urgent intervention at screening or randomizations
