Keverprazan-Minocycline Dual Therapy vs Bismuth Quadruple Therapy for H. pylori Eradication
This trial tests whether a keverprazan-minocycline dual therapy can eradicate Helicobacter pylori as well as or better than a bismuth-based quadruple therapy in adults who haven’t had eradication treatment before.
-
Prevalence and possible role of non-H. pylori Helicobacter species in gastric conditions and cancers
Researchers will test stomach tissue from people with functional dyspeasia, various gastritis conditions, gastric cancer, and bariatric patients to see if non-H. pylori Helicobacter species are present.
-
Vonoprazan versus a proton pump inhibitor with vitamin D or probiotics added to triple antibiotics for H. pylori eradication
This trial tests whether replacing a PPI with vonoprazan and adding vitamin D or a probiotic to standard clarithromycin–amoxicillin therapy helps adults with H. pylori infection clear the bacteria.
-
Gastric cancer risk in carriers of high-risk Helicobacter pylori variants
This study will see if people carrying high‑risk genetic subtypes of H. pylori develop gastric cancer or precancerous lesions more often than people without those subtypes.
-
7-day tailored treatment to eradicate H. pylori infection
This will test whether a 7-day treatment chosen using H. pylori culture and antibiotic susceptibility works better than the usual 10-day sequential regimen for adults with H. pylori infection.
