Study of SZC and Enhanced Nutrition Advice Compared to SoC in Dialysis Patients With Hyperkalaemia

This is a Phase IV, randomised, controlled, open-label, parallel-group, multicentre, prospective study to evaluate the effect of the combination of SZC and enhanced nutritional advice to consume fruit and vegetables as compared to SoC in reducing S-K+ levels in participants with hyperkalaemia on haemodialysis. Following 7-day screening, all participants who are enrolled will begin an up to 1-month HK Treatment Phase with SZC as per local label. Participants will receive dietary advice consistent with SoC at that site, including K+ restriction. A 4-month Diet Comparison Phase will begin next with participants being randomised to either continue taking SZC, which can be titrated as needed to maintain target S-K+ , and receive enhanced nutritional advice to consume fruit and vegetables (SZC arm), or SZC will be withdrawn and participants will receive SoC, including dietary K+ restriction (SoC arm).
