Exploratory Study of ZG-801 for the Treatment of Hyperkalemia

Phase 2
Completed
Conditions
Hyperkalemia
Interventions
Drug: placebo
Registration Number
NCT03799926
Lead Sponsor
Zeria Pharmaceutical
Brief Summary

To investigate the efficacy of each ZG-801 starting dose and the titration algorithm of ZG-801 for the treatment of hyperkalemia in Japanese patients.

To evaluate the safety of ZG-801 for the chronic use (total over 52 weeks). In addition, to confirm the safety after the discontinuation of ZG-801 treatment on 1 week follow-up.
