Helicobacter Pylori Infection Clinical Trial
Official title:
Susceptibility-Guided Sequential Therapy Versus Empirical Therapy for Helicobacter Pylori Infection: a Randomised Controlled Trial
The main objective of this trial is to assess whether a sequential therapy strategy based on molecular antibiotic susceptibility testing (including clarithromycin and fluoroquinolone) for H. pylori infection will improve the eradication rate compared to an empirical therapy.
This trial is designed as a prospective, randomised, open-label, active-controlled and single-centre study. For empirical therapy group(control group), Bismuth quadruple therapy will be an empirical first-line therapy, and high dose dual (proton-pump inhibitor + amoxicillin) treatment will be for rescue therapy if the first-line empirical treat failure. For the susceptibility-guided sequential therapy group, regimens were selected based on H. pylori susceptibility to clarithromycin and levofloxacin. The primary outcome is the first-line eradication rate in both groups, and the overall (including first- and rescue therapies) H. pylori eradication rates in both groups is one of the secondary outcomes. The eradication rates of H. pylori will be analysed by intention-to-treat analysis, modified intention-to-treat analysis and per-protocol analysis. ;
