A Phase 4 study testing Tetracyclin in people with Helicobacter Pylori Infection, run by Shandong University at 1 site in China.
Trial summary
The researchers collect H.pylori-positive patients who need rescue therapy from the outpatient clinic. The subjects were randomized to receive a dose and frequency of tetracycline 500mg tid or qid of bismuth quadruple eradication therapy. 6-8 weeks after treatment, the subjects will re-take the 13C-urea breath test.

About this study
Official title: Bismuth Quadruple Therapy for Helicobacter Pylori Rescue Therapy: A Multicenter Randomized Non-Inferiority Trial of Different Tetracycline Doses and Frequencies.
The researchers collect H.pylori-positive patients who need rescue therapy from the outpatient clinic. The subjects were randomized to receive a dose and frequency of tetracycline 500mg tid or qid of bismuth quadruple eradication therapy. 6-8 weeks after treatment, the subjects will re-take the 13C-urea breath test. Calculate the eradication rates, adverse reaction rates and patient compliance of each group.
Read the detailed description
The researchers collect H.pylori-positive patients who need rescue therapy from the outpatient clinic. If the subject meets the selection criteria but not the exclusion criteria, and signs an informed consent form, the researchers randomized the subjects in groups: subjects received a dose and frequency of tetracycline 500mg tid or qid of bismuth quadruple eradication therapy. The medication of groups are as follows. 6-8 weeks after the eradication treatment, the subjects will review the 13C-urea breath test, and the researcher records the results.
After all subjects were tested, the eradication rates, adverse reaction rates and patient compliance of each group were calculated.
According to the dose and frequency of tetracycline, it is randomized into a tid treatment group and a qid treatment group. The two groups of bismuth quadruple regimens are the same, as follows:
Tid group: Amoxicillin 1000mg bid+ Tetracycline 500mg tid+ Bismuth + Esomeprazole 40mg bid Qid group: Amoxicillin 1000mg bid+ Tetracycline 500mg qid+ Bismuth + Esomeprazole 40mg bid

What is being measured
The primary outcome is the main question the study is designed to answer.
Eradication rate
Both intention to treat (ITT) and per-protocol (PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infections in two groups. The ITT analysis includes all randomly assigned patients who take at least one dose of the study medications. The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.
Measured: Immediately after follow-up check
Secondary outcomes (2)
Rate of adverse reactions
Rate of adverse reactions

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Tetracyclin in people with Helicobacter Pylori Infection, run by Shandong University at 1 site in China.
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 3 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 31 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yanqing Li, Ph.D (18560089751, liyanqing@sdu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Eradication rate (time frame: Immediately after follow-up check). 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 NCT05432115, which also lists 8 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 31 Jan 2023; AzTrials last refreshed its copy on 8 Nov 2026.
