NCT05549115

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • the first-line H. pylori eradication rate

    the proportion of participants with successful H. pylori eradication, as determined by 13C-Urea breath test(UBT), at least 4 weeks after the end of the first-line treatment period between Susceptibility-guided therapy(SGT) and empirical therapy(ET) group.

    4-8 weeks after the end of treatment.

Secondary Outcomes (4)

  • the rescue H. pylori eradication rate

    4-8 weeks after the second treatment

  • the overall H.pylori eradication rate

    4-8 weeks after the second treatment

  • high-dose dual therapy eradication rate

    4-8 weeks after the second treatment

  • Adverse events and compliance

    3 days after the end of treatment.

Study Arms (6)

clarithromycin-sensitive(first-line)

EXPERIMENTAL

If H. pylori is sensitive to clarithromycin, we will administer clarithromycin triple therapy-esomeprazole (20 mg, twice daily), clarithromycin (500 mg, twice daily), and amoxicillin (1.0 g, twice daily)-for 14 days

Drug: clarithromycin-sensitive(first-line)

clarithromycin-resistant(first-line)

EXPERIMENTAL

If H. pylori is clarithromycin resistance, we selected the High-dose dual therapy (HDDT) regimen as first-line treatment. HDDT-esomeprazole (20 mg, four times daily) and amoxicillin (750 mg, four times daily)-will be used for 14 days.

Drug: clarithromycin-resistant(first-line)

empirical therapy group first-line

ACTIVE COMPARATOR

The empirical therapy group will receive Bismuth-containing quadruple therapy(BQT) as first-line treatment, The BQT regime is comprising of esomeprazole (20 mg, twice daily), colloidal bismuth pectin (150 mg, four times daily), clarithromycin (500 mg, twice daily), and amoxicillin (1.0 g, twice daily) for 14 days.

Drug: empirical therapy group first-line

levofloxacin-sensitive(rescue treatment)

EXPERIMENTAL

If H. pylori was levofloxacin-sensitive, we will use the levofloxacin quadruple regimen as rescue treatment-esomeprazole (20 mg, twice daily), levofloxacin (500 mg, once daily), amoxicillin (1.0 g, twice daily), and colloidal bismuth pectin (150 mg, four times daily)-for 14 days.

Drug: levofloxacin-sensitive(rescue treatment)

levofloxacin-resistant(rescue treatment)

EXPERIMENTAL

If H. pylori was levofloxacin-resistant, we will use furazolidone quadruple regimen as rescue treatment-esomeprazole (20 mg, twice daily), furazolidone (100 mg, twice daily), amoxicillin (1.0 g, twice daily), and colloidal bismuth pectin (150 mg, four times daily)-for 14 days.

Drug: levofloxacin-resistant(rescue treatment)

empirical therapy group rescue treatment

ACTIVE COMPARATOR

If BQT fails, HDDT-esomeprazole (20 mg, four times daily) and amoxicillin (750 mg, four times daily)-will be used as a rescue treatment for 14 days.

Drug: empirical therapy group rescue treatment
