What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a 14-day triple therapy—combining bismuth, tetracycline, and rabeprazole—can eradicate Helicobacter pylori as effectively as the standard bismuth quadruple therapy, which adds a fourth drug. About 300 adults with an H. pylori infection will be randomly assigned to one of the two treatments. The study compares eradication rates and side effects, aiming to see if the simpler regimen can become a new first-line option with fewer adverse reactions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A 14-day course of bismuth, tetracycline, and rabeprazole (triple therapy) compared with a standard bismuth quadruple therapy that also includes metronidazole.
What this could lead to
If successful, this simpler triple therapy could become a new first-line standard for eradicating H. pylori, with fewer side effects and better adherence than current quadruple regimens.
What could go wrong
This is a single-center trial, and the simpler regimen may prove less effective or still cause side effects. Results may not apply broadly to other populations or regions.
