Recruiting studies
- NCT07770126Recruiting
Stomach bacteria study for gastric conditions and precancer
This study looks for certain stomach bacteria (other than the common H. pylori) that might be linked to stomach diseases or early signs of cancer. If you have a stomach condition, your participation could help doctors understand these bacteria better.
EdegemAges 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+ - 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+ - NCT06421324Recruiting
AI-guided health advice for stomach conditions
This trial tests whether a personalized AI program can give you better health advice based on your stomach condition. It is for people who have gastric intestinal metaplasia (GIM) or have had H. pylori infection and are already scheduled for a gastroscopy.
ValenciaAges 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.
Kaohsiung CityAges 18 years+ - 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 - 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 - NCT04728516RecruitingPhase 4
Eradication treatment versus acid pills to prevent GI bleeding
This trial compares a “dual eradication therapy” (to get rid of H. pylori in the stomach) versus usual acid-reducing pills (PPIs) to lower the risk of gastrointestinal bleeding in people with recent heart artery disease treated with a stent. It may help by reducing stomach infection-related bleeding while you continue needed heart medicines.
Bozhou, AnhuiAges 18 years+ - NCT04191551Recruiting
Study of stomach precancer conditions during endoscopy
This study looks at people with certain stomach symptoms or precancer risk factors when they get a camera test of the upper digestive tract (endoscopy). The goal is to learn how to better detect and evaluate stomach precancer conditions early, which may help guide treatment or follow-up.
Stanford, CaliforniaAges 35–84 - NCT07344506RecruitingPhase 4
Cure H. pylori: New combination therapy for stomach infection
This trial tests a new combination of medications to treat H. pylori, a common stomach infection that can cause ulcers. It aims to find a more effective treatment with fewer side effects.
KarachiAges 18 years+ - NCT05053945Recruiting
Track stomach changes after H. pylori infection
This study follows adults with past or current H. pylori infection to better understand stomach lining changes such as atrophic gastritis and intestinal metaplasia, and to monitor for possible progression. It may help by improving how doctors track risk over time and use stored tissue samples to learn more.
Hong KongAges 18 years+ - 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 - NCT06349486Recruiting
Comparing new treatments for H. pylori infection
This trial compares three different medication combinations to see which works best for treating H. pylori infection. If you have H. pylori and haven't been treated yet, you may be able to join.
Kaohsiung CityAges 18 years+ - NCT04521764RecruitingPhase 1
Vaccine for Metastatic Breast Cancer
This trial tests a vaccine (MV-s-NAP) that is injected directly into a tumor to stimulate your immune system against breast cancer. It is for people with metastatic breast cancer that has spread despite prior treatments.
