Efficacy and Safety of Sodium Zirconium Cyclosilicate for Treatment of Hyperkalemia: An 11-Month Open-Label Extension of HARMONIZE.

ABSTRACT:

Background

Sodium zirconium cyclosilicate (SZC; formerly ZS-9) is a selective potassium (K+) binder for treatment of hyperkalemia. An open-label extension (OLE) of the -HARMONIZE study evaluated efficacy and safety of SZC for ≤11 months.

Methods

Patients from HARMONIZE with point-of-care device i-STAT K+ 3.5-6.2 mmol/L received once-daily SZC 5-10 g for ≤337 days. End points included achievement of mean serum K+ ≤5.1 mmol/L (primary) or ≤5.5 mmol/L (secondary).

Results

Of 123 patients who entered the extension (mean serum K+ 4.8 mmol/L), 79 (64.2%) completed the study. The median daily dose of SZC was 10 g (range 2.5-15 g). The primary end point was achieved by 88.3% of patients, and 100% achieved the secondary end point. SZC was well tolerated with no new safety conc
