A Phase 4 study testing Modified bismuth-containing eradication treatment in people with Helicobacter Pylori Gastritis and Helicobacter Eradication, run by Athens Medical Center.
Trial summary
The goal of this clinical trial is to learn if a modified bismuth-containing therapy for the treatment of helicobacter pylori infection works to treat chronic helicobacter pylori related gastritis in adults treated either for first time or after a previous failure of another helicbacter erdication therapy.

About this study
Official title: Clinical Evaluation of a 14day Modified Bismuth Quadruple Therapy for the Eradication of H. Pylori in a High Clarithromycin and Metronidazole Resistance Area
The goal of this clinical trial is to learn if a modified bismuth-containing therapy for the treatment of helicobacter pylori infection works to treat chronic helicobacter pylori related gastritis in adults treated either for first time or after a previous failure of another helicbacter erdication therapy. It will also learn about the safety and compliance of the modified bismuth containing therapy for helicobacter pylori.
The main questions it aims to answer are:
Read more
Does the modified bismuth-containing therapy for helicobacter pylori maintains a high eradication profile? What medical problems do participants have when taking the bismuth containing therapy? Researchers will present the eradication percentage of the modified bismuth containing therapy for helicobacter pylori in a difficult to treat population with a high profile of resistance to antibiotics for the treatment of helicobacter pylori separately for first time treated patients or patients with previous failures of other therapies.
Participants will:
Take the modified bismuth containing therapy which consists of four different medications (esomeprazole, amoxicillin, metronidazole, bismuth subcitrate) taken for 14 days in selected timepoints.
Visit the clinic at the end of therapy for checkups and at 6 to 8 weeks after the end of therapy for final evaluation of completed eradication.
Keep a diary of their symptoms and the number of medications taken.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Modified bismuth-containing eradication treatmentDrug
After the confirmation of Helicobacter pylori infection, eligible patients whether first line or rescue therapy will be assigned to receive:
- A modified and optimized bismuth quadruple therapy that comprises: 40 mg of esomeprazole bid, amoxicillin 1g tds, metronidazole 500mg tds and bismuth subcitrate 240mg bid, all medications taken for 14 days.
Esomeprazole will be given at least 30 minutes before meals every 12 hours. Antibiotics will be given after meals every 8 hours and bismuth subcitrate at least 2 hours far from meals every 12 hours.
| Study group | Role | What they receive |
|---|---|---|
| Helicobacter pylori infected | Active comparator | This arm will include patients who have to receive eradication therapy for the first time as first line or experienced patients who have to receive eradication as rescue therapy for third or further line, respectively. Receives: Drug: Modified bismuth-containing eradication treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Effectiveness to eradicate helicobacter pylori with modified bismuth-containing treatment
Participants achieved helicobacter pylori eradication if they perform negative at 13C-urea breath test (13C-UBT) 6-8 weeks after completion of modified bismuth-containing treatment
Measured: From enrollment to the end of treatment and assessment of eradication results at 8-10 weeks
Secondary outcomes (1)
Secondary outcomes are to assess patient's compliance and adverse events
Side effects of treatment will be assessed on a structured clinical interview with a specific questionnaire completed immediately after the end of eradication therapy and at the final re-evaluation at 8 weeks. During the interview, patients will be asked to grade the severity of each adverse event experienced as "mild" (transient and well tolerated), "moderate" (causing discomfort and partially interfering with common everyday activities), or "severe" (causing considerable interference with patients' daily activities). Incapacitating or life-threatening complications will be classified as serious and will be reported to regulatory agency (National Organization of Medicines). Adherence to treatment will be assessed by providing all patients with a pre-structured printed table with all dosages illustrated, asking to tick each time a pill was consumed and bring it back along with any tablet not consumed, for pill counting.
Measured: From enrollment to the end of evaluation at 8 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Modified bismuth-containing eradication treatment in people with Helicobacter Pylori Gastritis and Helicobacter Eradication, run by Athens Medical Center.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 28 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effectiveness to eradicate helicobacter pylori with modified bismuth-containing treatment (time frame: From enrollment to the end of treatment and assessment of eradication results at 8-10 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07146594, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2025.
