Safety & Efficacy of Zirconium Silicate Dosed for 28 Days in Hyperkalemia.

Summary

It is hypothesized that ZS is more effective than placebo control (alternative hypothesis) in maintaining mean double-blind randomized maintenance phase (DBRMP) Day 8-29 serum potassium levels (3.5 - 5.0 mmol/l, inclusive) among hyperkalemic subjects in whom normokalemia was established during the open-label acute phase versus no difference between each ZS dose (highest to lowest) versus placebo control (null hypothesis).
