Conditions

Hyperkalemia

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

DRUGCalcium, 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.

DRUGPlacebo

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

Inclusion criteria

* Patients whose serum potassium value (local) at the Run-in period baseline is ≥5.5mEq/L, \< 6.5 mEq/L * Age 20 - 80 years old at informed consent * Patients who understand an overview of the study and voluntarily consented to participate in the study by documents. Main

Exclusion criteria

* Patients determined to require emergency treatment for hyperkalemia at the Run-in period baseline * Patients with poorly controlled blood pressure * Patients with heart failure in New York Heart Association Class IV * Patients who have experienced heart transplant, liver transplant or kidney transplant or who are predicted that the need for them will occur during the study * Patients who have taken any of the following medication within 7 days prior to the Run-in period baseline or currently administrated. 1. Sodium polystyrene sulfonate 2. Calcium polystyrene sulfonate 3. Sodium zirconium cyclosilicate hydrate 4. Potassium supplement * Patients with or who have experienced a severe swallowing disorder, moderate to severe gastroparesis, severe constipation, bowel obstruction, incarceration, abnormal post-operative bowel motility disorders or severe gastrointestinal disorders. In addition, patients who have experienced bariatric surgery or major gastrointestinal surgery (e.g., bowel resection). * Patients suspected to be with transient high potassium value.(ex. caused by dietary effects only)
