Clinical Trial Summary

This study aims to compare the efficacy of the current standard first-line anti-helicobacter pylori regimen, extended proton pump inhibitor-based sequential therapy, with that of vonoprazan-based triple therapy, through a randomized controlled trial.

Description:

Helicobacter pylori infection is a well-established risk factor for peptic ulcer disease and gastric cancer. It's now a consensus of experts that H.pylori infection should be treated once it is recognized. Extended proton pump inhibitor (PPI)-based sequential therapy as one of the most commonly used first-line regimens provides a satisfactory eradication rate of 90.7% (95% CI, 87.4% - 94.0%). Nevertheless, its complexity of the "sequential" usage is sometimes confusing to the patients and may lead to treatment failure. The emerging new regimen - vonoprazan-based triple therapy, on the other hand, is another appealing choice with simplicity, short treatment duration, and low pill burden. However, there's still no evidence regarding the use of vonoprazan-based triple therapy with high-dose amoxicillin (1000mg twice daily) as the first-line regimen. This study aimed to compare the efficacy of the current standard first-line regimen, sequential therapy, with that of vonoprazan-based triple therapy with high-dose Amoxicillin.
