NCT02679508

Brief Summary

The purpose of this study is exploratorily evaluate the effect on gastric mucosal tissue and the safety of long-term administration (260 weeks: 5 years) of vonoprazan 10 mg or 20 mg in patients receiving maintenance treatment after healed erosive esophagitis (EE), and the curative effect of vonoprazan 20 mg versus lansoprazole in patients with EE.
