A Comparative Study of ZG-801 and Placebo in Patients With Hyperkalemia
Study Details
Study Description
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.

Drug: Placebo
Placebo is powder for suspension. In Double-blind period, Placebo is taken once a day for 4 weeks.

Outcome Measures
Primary Outcome Measures
- Change in serum potassium value at Double-blind period week4 [Double-blind period baseline to Double-blind period week4]
Secondary Outcome Measures
- Maintenance of serum potassium value within 3.5 mEq/L to < 5.1 mEq/L or within 3.5 mEq/L to <5.5 mEq/L in Double-blind Period [Double-blind period baseline to Double-blind period week4]
- Time to First Non-maintenance of Serum Potassium Value in Double-blind Period [Double-blind period baseline to Double-blind period week4]
- RAASi dose sustaining proportion [Double-blind period baseline to Double-blind period week4]
- Change in Serum Potassium Value [Run-in period baseline to Run-in period week 5]
