An Open-Label, Randomised, Phase 4 Study of Continuing Sodium Zirconium Cyclosilicate (SZC) After Discharge in Participants With Chronic Kidney Disease Treated for Hyperkalaemia

AstraZeneca·interventional·Posted Apr 26, 2022·Updated Nov 28, 2025

In Brief

A Phase 4 clinical trial evaluating Sodium Zirconium Cyclosilicate (SZC) and Local standard of care for Hyperkalaemia and Chronic Kidney Disease. Completed, enrolled 186 participants across 28 sites in 6 countries.

Detailed Summary

This is an open-label, randomised study in participants with chronic kidney disease (CKD) treated for hyperkalaemia (HK) whilst in hospital. The study will compare SZC to standard of care (SoC) with the goal of determining: * If continued use of SZC maintains normokalaemia (NK) better than SoC after participant discharge from the hospital. * If continued use of SZC after discharge will reduce HK related healthcare resource utilisation compared to SoC.
