Study summary

Helicobacter pylori (H. pylori) infection is a common global infectious disease of the gastrointestinal tract. Helicobacter pylori eradication can effectively prevent the development of stomach cancer. Progressive application of dual therapy for the eradication of Helicobacter pylori. Tegoprazan, a Potassium-Competitive Acid Blockers. The efficacy of P-CAB agents represented by vonoprazan in H. pylori eradication therapy has been widely verified.

Read the detailed description

In 1989, it was suggested that amoxicillin combined with PPI could eradicate Hp infection, and in 2015, a prospective, multicenter, randomized controlled study in Taiwan with a large sample showed that the eradication rate of Hp could reach 96.6% with dual therapy for primary treatment of Hp infection, and the results of intention-to-treat analysis were as high as 95.3%. 95.3%. In 2020, a meta-analysis showed that high-dose dual therapy had the same efficacy and fewer side effects than other recommended regimens in first-line treatment. In terms of dosing days, multiple randomized controlled studies and meta-analyses from 2020-2021 have shown that 14 days of high-dose dual therapy is more effective in eradicating H. pylori.

Tegoprazan, a Potassium-Competitive Acid Blockers (P-CAB), is a new type of acid-suppressing drug that compensates for the short half-life of acid-activated traditional acid-suppressing PPI and the low mucosal healing rate due to insufficient acid suppression. The efficacy of P-CAB agents represented by vonoprazan in H. pylori eradication therapy has been widely verified. 2022, tegoprazan was approved by the State Drug Administration for the new indication of eradication of H. pylori infection in adults in combination with appropriate antimicrobial therapy, and its efficacy in clinical application has not yet been verified.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Helicobacter pylori infection (either positive for histopathological test, rapid urease test, or C13/C14 urea breath test).
  • Patients who have not previously received helicobacter pylori eradication therapy.

Exclusion criteria

Exclusion Criteria:

  • Serious underlying diseases, such as liver insufficiency, renal insufficiency, , malignant tumor, coronary heart disease (angina pectoris or coronary artery stenosis ≥ 75%).
  • Those who are not willing to take measures during pregnancy, lactation or the trial.
  • Active gastrointestinal bleeding.
  • History of drug allergy.
  • History of upper gastrointestinal surgery.
  • Medication history of bismuth, antibiotics and PPI within 4 weeks.
  • Other behaviors that may increase the risk, such as alcohol and drug abuse.
  • Unable or unwilling to provide .
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. 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 80% of the study medications and complete follow-up.

    Time frame: Immediately after follow-up check

Secondary outcomes

  1. Rate of adverse reactions

    Rate of adverse reactions

    Time frame: Immediately after follow-up check

  2. Patient compliance

    good compliance is defined as the actual dosage is within the range of 80%-100% of the dosage that should be taken

    Time frame: Immediately after follow-up check

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 11, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
