About this study
Official title: Efficacy of 7-day Versus 14-day Bismuth Quadruple Therapy for the Eradication of Helicobacter Pylori : A Multicenter Randomized Non-Inferiority Trial
Helicobacter pylori (H. pylori) infection is a common global infectious disease of the gastrointestinal tract. Helicobacter pylori eradication can effectively prevent the development of gastric cancer.The researchers collect H.pylori-positive patients who need native therapy. The subjects were randomized to receive7 days and 14 days 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
Related studies have shown that 7-day bismuth quadruple therapy is not inferior to 14-day bismuth quadruple therapy in the eradication of clarithromycin-resistant H. pylori.The results of the current study conducted by our team on the eradication of H. pylori in 10-day versus 14-day courses of bismuth quadruple therapy showed that the 10-days (92.09%) was not inferior to the 14-days(92.38%), but the incidence of adverse effects was significantly lower in the 10-day courses than in the 14-days(30.62%). If it can be demonstrated that the eradication rate of the 7-day course of bismuth quadruplex is close to that of the 14-days, then the 7-day course may be chosen.
The researchers collect H.pylori-positive patients who need native therapy. 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 7days or 14days 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 therapy, it is randomized into a 7days treatment group and a 14 days treatment group. The two groups of bismuth quadruple regimens are the same, as follows:
7days group: Amoxicillin 1000mg bid+ Tetracycline 500mg qid+ Bismuth + Tegoprazan 50mg bid 14days group: Amoxicillin 1000mg bid+ Tetracycline 500mg qid+ Bismuth + Tegoprazan 50mg bid
- Conditions
- Helicobacter Pylori Infection
- Being tested
- 7days bismuth quadruple, 14 days bismuth quadruple

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
Measured: Immediately after follow-up check
Patient compliance
Good compliance is defined as the actual dosage is within the range of 90%-100% of the dosage that should be taken.
Measured: Immediately after follow-up check

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Helicobacter pylori (H. pylori) infection is a common global infectious disease of the gastrointestinal tract. Helicobacter pylori eradication can effectively prevent the development of gastric cancer.The researchers collect H.pylori-positive patients who need native therapy. The subjects were randomized to receive7 days and 14 days 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.
Detailed description

According to therapy, it is randomized into a 7days treatment group and a 14 days treatment group. The two groups of bismuth quadruple regimens are the same, as follows:
7days group: Amoxicillin 1000mg bid+ Tetracycline 500mg qid+ Bismuth + Tegoprazan 50mg bid 14days group: Amoxicillin 1000mg bid+ Tetracycline 500mg qid+ Bismuth + Tegoprazan 50mg bid
