Overview
- Compare the efficacies and safety of 14-day bismuth-amoxicillin-vonoprazan tiple therapy, 14-day vonoprazan dual therapy and 14-day rabeprazole triple therapy in the first-line treatment of H. pylori infection.
- To investigate the impacts of antibiotic resistance of H. pylori as well as CYP3A4, CYP2C19 and IL-1B -511 genotypes of host on the eradication efficacies of anti-H. pylori treatments.
Description
For this multi-center, randomized, open-label, superiority trial, we will recruit 780 adult patients with H. pylori infection from ten medical centers or regional hospitals in Taiwan. Using a computer generated randomized sequence, we randomly allocate patients (1:1:1; block size of six) to either 14-day bismuth-amoxicillin-vonoprazan triple therapy, 14-day vonoprazan dual therapy, or 14-day rabeprazole-triple therapy. Patients are asked to return at the second week to assess drug adherence and adverse events. Post-treatment H. pylori status is assessed by 13C-urea breath test at week 6. Participants with failure of H. pylori eradication will randomly receive either 14-day vonoprazan-based or 14-day esomeprazole-based bismuth quadruple therapy. Finally, the rates of eradication and adverse events will be compared between groups by chi-square test. Additionally, the effects of antibiotic resistances of H. pylori as well as CYP3A4, CYP2C19 and IL-1B -511 genotypes of host on the eradication efficacies of above first-line and second-line anti-H. pylori treatments are assessed by multivariate analysis.
