Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

This multi-center trial will be conducted in China. The overall time to participate in this study is 10 weeks. Participants will make multiple visits to the clinic, and 28 days after last dose of study drug for a follow-up assessment.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1\. Helicobacter pylori (HP)-positive participants as determined by \^13C-urea breath test (\^13C-UBT) at the start of the study (Visit 1 \[screening\]) and who require HP eradication in Physician judgment.

Exclusion Criteria

1. Participant had any of the following conditions at the start of the study (Visit 1, screening): acute upper gastrointestinal bleeding, active gastric ulcer (GU) or duodenal ulcer (DU) characterized by defective mucos with white coating (with or without adherent blood clots) 3 mm or more in size, acute gastric mucosal lesion (AGML), or acute duodenal mucosal lesion (ADML). However, participants with gastritis, gastric or duodenal erosion are permitted to participate.
2. Participants with Zollinger-Ellison syndrome or gastric acid hypersecretion or those with a history of gastric acid hypersecretion.
3. Participant has a history of malignancy or was treated for malignancy within 5 years before the start of the screening visit (the participant may be included in the study if he/she has cured cutaneous basal cell carcinoma or cervical carcinoma in situ).
4. Participant has a known acquired immunodeficiency syndrome or hepatitis infection, including hepatitis virus carriers (hepatitis B surface antigen \[HBsAg\] or hepatitis C virus \[HCV\]- antibody-positive).
