Hyperkalemia
Conditions
Brief summary
The purpose of this study is to evaluate the superiority of ZG-801 to placebo in Japanese hyperkalemia patients whose serum potassium value becomes normal in the Run-in period by comparing the change in the value at the Double-blind period week 4, and to further evaluate the efficacy and safety of ZG-801 in Japanese hyperkalemia patients administrated ZG-801 for maximum 9 weeks.
Interventions
ZG-801 is powder for suspension. In Run-in period, ZG-801 is taken once a day for 4 or 5 weeks. In Double-blind period, ZG-801 is taken once a day for 4 weeks.
Placebo is powder for suspension. In Double-blind period, Placebo is taken once a day for 4 weeks.
