Gastric cancer study for people with high-risk H. pylori
This study follows people who carry a high-risk type of Helicobacter pylori (a stomach bacteria) to see if they develop gastric cancer. It aims to understand who is most at risk and how to monitor them over time.
TonglingAges 40 years+ - NCT06579365Recruiting
Registry on H. pylori Infection Management in Argentina
This registry study tracks how H. pylori infection is managed in Argentina. It aims to collect real-world data to improve treatment for this common stomach infection.
Ciudad de Buenos AiresAges 18 years+ - NCT02047994RecruitingPhase 4
Testing and treatment for H. pylori to prevent stomach cancer death
This trial studies whether testing for an infection called H. pylori and using simple blood/screening tests (pepsinogen testing) can help prevent stomach cancer and reduce stomach-cancer-related deaths. You would be followed for health outcomes to see if the approach works better than standard care.
RigaAges 40–64 - NCT07574879RecruitingPhase 1
H. pylori Treatment Effects on COPD Symptoms
This study tests whether treating a stomach bacteria infection (H. pylori) can improve breathing and lung function in people with COPD. Researchers want to see if eliminating this bacteria helps reduce COPD symptoms.
Zagazig, ElsharkiaAges 40 years+ - NCT05276557RecruitingPhase 3
Kids study of a breath test to check H. pylori
This Phase 3 study tests whether a urea breath test (a safe breath test) works well and is safe for children ages 3–17. It may help doctors find and manage an H. pylori infection without using repeated samples.
Doral, FloridaAges 3–17 - NCT06660342Recruiting
Safety of vonoprazan in pregnant women study
This study looks at the safety of vonoprazan (a medicine for acid reflux) when taken during pregnancy. It follows pregnant women who took the drug and those who didn't, to see how it affects mothers and their babies.
Wilmington, North CarolinaAges 15–50 - NCT07010744Enrolling by invitation
Comparing 3 vs 4 drugs for H. pylori infection
This study compares two treatment plans for H. pylori infection (a stomach bacteria). It looks at whether a 3-drug combination works as well as a 4-drug combination to clear the infection.
DhakaAges 18 years+ - NCT06929962RecruitingPhase 4
VA dual sequential therapy for H. pylori gastritis
This trial tests a new two-step antibiotic treatment for adults with chronic gastritis caused by H. pylori bacteria. If you have not been treated for H. pylori before and are between 18 and 70, you may be able to join.
Nanjing, JiangsuAges 18–70 - NCT07232095RecruitingPhase 4
7-Day treatment for H. pylori with new acid blocker and antibiotics
This trial tests a 7-day combination of vonoprazan, high-dose amoxicillin, and bismuth to treat Helicobacter pylori infection in people who have never been treated for it before. The goal is to see if this short course is effective and safe for curing the infection.
Nanjing, JiangsuAges 18–70 - NCT05681689RecruitingPhase 3
Check how well a urea breath test works after H. pylori treatment
This Phase 3 study tests whether a urea breath test can confirm that H. pylori infection has been cleared after recent treatment. If the test works well, it may help doctors confirm cure without needing invasive procedures.
Doral, FloridaAges 18 years+ - NCT07358130Recruiting
Comparing two treatments for H. pylori infection
This trial tests two different ways to treat Helicobacter pylori (H. pylori), a bacteria that can cause stomach ulcers. One treatment combines three medicines (bismuth, amoxicillin, and vonoprazan), and the other uses four medicines (bismuth quadruple therapy). The goal is to see which works better.

Study of stomach precancer conditions during endoscopy

- How do I know if I qualify for a helicobacter pylori trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a helicobacter pylori trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
