New triple therapy aims to wipe out stomach bug h. pylori
NCT ID NCT07875933
First seen Oct 15, 2026 · Last updated Oct 16, 2026 · Updated 1 time
Summary
Researchers are testing a triple therapy built around JP-1366, combined with clarithromycin and amoxicillin, to see whether it clears Helicobacter pylori infection in adults. The trial enrolls about 414 people aged 19 to 75 with confirmed H. pylori. Participants receive either the JP-1366 regimen or a standard lansoprazole-based triple therapy, and researchers compare how well each clears the infection at least four weeks after treatment ends.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JP-1366 plus clarithromycin and amoxicillin
- What this could lead to
- If it works, this could offer another triple-therapy option for clearing H. pylori, a common stomach infection linked to ulcers and stomach cancer.
- What could go wrong
- The trial may show JP-1366 is less effective than standard lansoprazole, or that side effects or resistance limit its usefulness. Results in this adult group may not apply to other populations.
