Brief Summary

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

The study aims to test the efficacy of 7 days vs. 14 days of Vonoprazan-triple therapy in the eradication of Helicobacter Pylori infection in adolescents and young children.

Detailed Description

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

After being informed about the study details, all eligible participants (or their legal guardians) will give informed written consent to be involved. After a one week screening, eligible participants will be randomized to Vonoprazan plus Amoxicillin plus Clarithromycin triple therapy for either 14 days (group 1), or 7 days (group 2) at a 1:1 ratio. After the end of therapy, H. Pylori eradication will be evaluated after 4 weeks.
