A Study to Evaluate the Efficacy and Safety of Bismuth-Containing Quadruple Therapy With Oral Vonoprazan (TAK-438) 20 mg Compared to Esomeprazole 20 mg Twice Daily in Paticipants With Helicobacter Pylori Infection

Helicobacter Pylori Clinical Trial

Official title:
A Randomized Double-Blind, Phase 3 Study to Evaluate the Efficacy and Safety of Bismuth-Containing Quadruple Therapy With Oral TAK-438 20 mg Compared to Esomeprazole 20 mg Twice Daily in Subjects With Helicobacter Pylori Infection

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy of helicobacter pylori (HP) eradication with bismuth-containing quadruple therapy with vonoprazan versus esomeprazole in all HP-positive participants.

Clinical Trial Description

The drug being tested in this study is called vonoprazan (TAK-438). Vonoprazan is being tested to treat people who have helicobacter pylori infection. The study is planned to enroll 425 patients at the beginning and will enroll a maximum of approximately 510 patients based on the interim analysis results. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need): Vonoprazan 20 mg Esomeprazole 20 mg All participants will be asked to take one tablet in combination with bismuth containing quadruple therapy (amoxicillin, clarithromycin and bismuth potassium citrate) twice at the same time each day throughout the study.
