Recruiting studies
- NCT05874570RecruitingPhase 4

Bangkok Noi, BangkokAges 18 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 - NCT05061732RecruitingPhase 4

It aims to see if adding the probiotic helps the treatment work better and cause fewer side effects.
Xi'an, ShaanxiAges 18–75 - 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 - NCT05762991Recruiting
AI test to help diagnose stomach bacteria and early stomach changes
This trial checks whether an artificial intelligence (computer) system can help diagnose Helicobacter pylori (a common stomach bacteria) and early stomach “premalignant” changes using endoscopy results. It may help doctors spot problems more accurately when you have a scheduled scope.
TaipeiAges 20–80 - NCT06168214RecruitingPhase 4
Comparing treatments for H. pylori infection
This study compares several different 2-week treatment plans to see which works best for wiping out H. pylori, a bacteria that can cause stomach ulcers and other digestive problems. If you have H. pylori, you may be able to join and receive one of the treatments.
Xi'an, ShaanxiAges 18–70 - NCT06558578Recruiting
Helicobacter pylori infection and migraine in children
This study looks at whether a stomach infection (Helicobacter pylori) is linked to migraine headaches in children. If your child has migraines, this trial could help find a possible connection.
SohagAges 6–16 - NCT06509139Enrolling by invitationPhase 4
Finding the best treatment length for H. pylori infection
This study tests how long (10 or 14 days) a combination of four medicines (bismuth quadruple therapy) should be taken to best treat H. pylori infection, and whether the best duration differs between women and men. It aims to find the shortest effective treatment to reduce side effects.
TainanAges 18–100 - NCT06382493Recruiting
Tegoprazan sequential therapy for H. pylori infection
This study tests a new treatment plan using a medicine called tegoprazan for people with H. pylori, a bacteria that can cause stomach ulcers. The goal is to see if this sequential treatment works better at clearing the infection.
Seongnam-si, Gyeonggi-doAges 18 years+ - NCT07306988RecruitingPhase 4
Treating H. pylori to improve metabolic syndrome
This trial tests whether treating H. pylori infection can help improve metabolic syndrome (a group of conditions like high blood sugar, abnormal cholesterol, and high blood pressure). It aims to understand how treatment changes your gut bacteria and overall health.
Nanjing, JiangsuAges 18–65 - NCT05926804Recruiting
Screening and treatment for Helicobacter pylori in teens
This trial checks teenagers for a long-lasting H. pylori stomach infection and then treats those who need it. It may help prevent ongoing stomach problems from the infection and compare outcomes between treated and non-treated groups.
CoyhaiqueAges 14–18 - NCT07179159Recruiting
14-day stomach infection treatment study
This study compares two treatments for an H. pylori stomach infection: taking two medicines (vonoprazan and amoxicillin) versus taking four medicines. Both treatments are given for 14 days.
Jinan, ShandongAges 18–70 - 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+ - 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+ - 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 - NCT07165444Recruiting
Comparing two acid-blocking drugs for H. pylori treatment
This trial tests if a newer acid-blocking medicine works better than a standard one when given with antibiotics and bismuth for treating H. pylori infection, a bacteria that can cause stomach ulcers. It is for adults who have not had treatment for H. pylori before.
Tanta, El-GharbiaAges 18 years+ - 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+ - NCT07516262Recruiting
How Stomach Acid Medication Affects H. Pylori Detection
This study looks at whether a common stomach acid medication (PPIs) affects the accuracy of a stool test for detecting H. pylori, a bacteria that can cause ulcers and stomach inflammation. Understanding this helps doctors know when the stool test works best.
