Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 20 and older with H. pylori-positive chronic gastritis and a history of treatment failure.

Probably not a fit

Patients who are pregnant, nursing, or have serious concomitant illnesses or a history of hypersensitivity to the test drugs may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of susceptibility-guided tailored therapy (SG-TT) versus guidelines-recommended empiric therapy (GR-ET) for patients with Helicobacter pylori infection who have previously failed treatment. It will involve a multicenter, randomized approach where patients will be assigned to one of the two treatment groups based on a randomization process. The study will also assess patient adherence, adverse effects, and factors influencing treatment success. Participants will be monitored throughout the treatment period to gather data on symptoms and medication use.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for patients suffering from Helicobacter pylori infections, particularly those who have not responded to previous therapies.

How similar studies have gone: Other studies have shown promising results with susceptibility-guided therapy approaches, indicating potential for success in this area.
