An Open-label Study to Assess Safety and Efficacy of SZC in Paediatric Patients With Hyperkalaemia

Sodium zirconium cyclosilicate has been shown to be effective and safe in adults for the treatment of hyperkalaemia, and therefore it is expected to be beneficial in children. This study will evaluate the efficacy, safety and tolerability of sodium zirconium cyclosilicate for the treatment of hyperkalaemia in children \<18 years of age. Approximately 140 participants will enter CP at approximately 46 sites in locations including but not limited to Europe and North America for this study. Treatment will include 3 phases: the CP, MP, and LTMP. Enrolment will start in 2 cohorts, ages 6 to \< 12 years and 12 to \< 18 years. After review of accumulated data, the independent Data Monitoring Committee (iDMC) will recommend whether to open enrolment in the ages 2 to \< 6 years cohort and later in the ages 0 to \< 2 years cohort. All eligible participants with hyperkalaemia will enter an open-label Correction Phase (CP) receiving a fixed dose of SZC three times daily (TID) for up to 3 days until normokalaemia is achieved. Within each age cohorts 2 to \< 18 years, initial participants will be allocated to the dose level (DL) based on body weight equivalent to an adult 5 g TID. After recommendation of higher DLs by the iDMC, subsequent participants may be allocated in the CP to on body weight equivalent to an adult 10 g TID and then potentially on body weight equivalent to an adult 15 g TID. All participants in the ages 0 to \< 2 years cohort will be assigned to the same DL which will b…
