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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: ZG-801

Drug: Calcium, hydrolysed divinylbenzene-Me 2-fluoro-2-propenoate-1, 7-octadiene polymer sorbitol complexes
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 Comparator: Placebo

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

  1. Change in serum potassium value at Double-blind period week4 [Double-blind period baseline to Double-blind period week4]

Secondary Outcome Measures

  1. 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]

  2. Time to First Non-maintenance of Serum Potassium Value in Double-blind Period [Double-blind period baseline to Double-blind period week4]

  3. RAASi dose sustaining proportion [Double-blind period baseline to Double-blind period week4]

  4. Change in Serum Potassium Value [Run-in period baseline to Run-in period week 5]
