High-dose dual therapy vs minocycline quadruple therapy for H. pylori
This trial compares two treatments for H. pylori infection: a high-dose two-drug regimen and a four-drug regimen containing minocycline. It aims to find which is more effective and better tolerated.
Hebi, HenanAges 18–70 - NCT06529159Recruiting
Treating H. pylori with argon plasma during endoscopy
This trial tests a new way to treat H. pylori infection using argon plasma (a kind of energy) during an upper endoscopy. It may help people who haven't yet taken antibiotics for H. pylori and are already having an endoscopy.
Boston, MassachusettsAges 18 years+ - NCT05329636RecruitingPhase 1/Phase 2
Fecal microbiome transplant after H. pylori antibiotic treatment
This trial tests whether transplanting healthy gut bacteria (from fecal material) can help your recovery and gut health after you take antibiotics to clear H. pylori (a stomach germ). If you qualify, you would start with confirmed H. pylori and then follow the study steps for the transplant.
Tel AvivAges 18–70 - NCT07704255RecruitingPhase 4
Fecal transplant for stubborn H. pylori infection
This study tries a fecal microbiota transplant (placing healthy donor stool into your gut) to get rid of stubborn H. pylori infection that hasn't been cured by standard treatments. It's for people who have failed several rounds of therapy and have a stomach condition that makes eradication important.
Chengdu, SichuanAges 18–80 - NCT07346521Recruiting
Stomach cancer screening during routine colonoscopy
This study looks for early signs of stomach cancer and Barrett's esophagus (a precancerous condition) in people who are already getting a routine colonoscopy. By adding a quick upper endoscopy during the same visit, doctors can check for H. pylori infection and abnormal tissue changes without extra hassle.
ViennaAges 30 years+ - NCT07724496Recruiting
H. pylori and stomach growth features study
This study looks at whether having H. pylori infection (a common stomach bacteria) and certain features of stomach growth can predict how early stomach cancer or pre-cancerous changes will behave and what your long-term outlook might be. You may be eligible if you are being treated with a camera-based removal procedure called endoscopic submucosal dissection (ESD).
Beijing, Beijing MunicipalityAges 18–80 - NCT04949737Recruiting
Study stomach bacteria and stomach cancer in Martinique adults
This study looks at how common Helicobacter pylori (a common stomach germ) is in adults with stomach cancer in Martinique, and how it relates to stomach cancer. It mainly involves answering questionnaires and allowing study details to be collected to better understand risk and patterns.
Fort-de-FranceAges 18 years+ - NCT05561504Recruiting
Study of stomach bacteria resistance in adults
This study looks at how common a stomach bacteria infection is and which antibiotics still work. You may help researchers by providing consent for related study participation and sample tracking.
MunichAges 18 years+ - NCT07068607RecruitingPhase 4
Comparing two treatments for H. pylori infection
This study tests whether a new stomach acid medicine called vonoprazan, combined with different antibiotics, works better than standard treatments to clear an H. pylori infection. It is for people who have never been treated for H. pylori and want to try a shorter, simpler treatment course.
Xi'an, ShaanxiAges 18–70 - NCT07083804Recruiting
Testing for H. pylori using stool samples in children
This study checks if a stool test can find H. pylori bacteria in children, instead of using a stomach biopsy during an endoscopy. It may help diagnose stomach issues with less discomfort.
PoitiersAges Up to 16 years - NCT07139366RecruitingPhase 4
Probiotic plus bismuth combo for stubborn H. pylori
This study tests a combination of a probiotic (Saccharomyces boulardii) plus a standard bismuth-based four-drug treatment for people whose H. pylori infection has not been cured by previous treatments. It aims to see if adding the probiotic helps the treatment work better and cause fewer side effects.
Xi'an, ShaanxiAges 18–75 - NCT07179237RecruitingPhase 2

This trial tests a new medicine called carminal for people with stomach inflammation caused by H. pylori bacteria. It aims to see if the drug can help improve symptoms like indigestion and get rid of the infection.
Belgrade, Central SerbiaAges 18 years+ - NCT07260006Recruiting
Bismuth therapy for H. pylori ulcers in children
This trial tests whether adding bismuth to standard treatment works better for children with stomach ulcers caused by H. pylori infection. If your child has been diagnosed with an H. pylori ulcer, this study could help find the best medicine.
Can ThoAges 5–15 - NCT07293910RecruitingPhase 2
Comparing treatments for H. pylori infection
